Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a rapid puncture inhaler. Background Technology

[0002] The conventional working principle of an inhaler is as follows: the user presses a button that drives the needle, causing the needle tip to pierce the capsule or other medication carrier. Simultaneously, pressing the button causes the inhaler's spring to deform elastically. When the user releases the button, the needle tip returns to its original position under the spring's force and withdraws from the medication carrier. The needle then retracts, creating a hole in the outer shell of the medication carrier. When the user inhales the medication, outside air enters the medication chamber, impacting the medication carrier inside and causing it to vibrate and / or rotate. The medication inside the carrier can then enter the outside world through the hole created by the needle tip. During the process of puncturing the drug carrier, the user presses the button to allow the needle tip to pierce the carrier. This requires overcoming not only the resistance of the carrier's outer shell to the needle tip but also the resistance from the spring inside the inhaler. For users with weaker hand strength, if they cannot forcefully pierce the carrier with the needle tip but instead drive it slowly, the carrier's outer shell may deform significantly. This can cause the outer shell to cave in within the drug compartment, potentially preventing the needle tip from piercing it and releasing the drug. Even if the needle tip does pierce the outer shell, the caved-in shape can affect the airflow and movement of the carrier during inhalation, hindering the expulsion of the drug from the outer shell. This can result in excessive drug residue within the carrier, impacting the therapeutic effect. This is especially problematic for high-value drug carriers, potentially causing significant financial losses for the user. Summary of the Invention

[0003] In order to ensure that the needle tip can quickly and smoothly pierce the outer shell of the drug carrier, reduce the degree of deformation of the outer shell of the drug carrier, ensure that the shape of the outer shell of the drug carrier remains as close as possible to the factory shape, and allow the drug carrier to shake and / or rotate smoothly under the impact of airflow so that the drug can smoothly enter the drug chamber and be inhaled by the user, this application provides a rapid piercing inhaler.

[0004] A rapid-puncture inhaler includes: a main body having a drug chamber for holding a drug carrier, the drug chamber having a connecting hole; a needle having a needle tip and being axially movable on the main body along the needle tip, the needle tip being able to enter and exit the drug chamber through the connecting hole along its axial direction, the needle performing a puncture action and a needle retraction action; an active member movably disposed on the main body along a first direction, having a blocking part; and a needle insertion unit including a working part one connected to the needle and a working part two connected to the active member or the main body, the working part two being elastically coupled or magnetically coupled to the working part one, the working part one having a tendency to move towards the drug chamber along the axial direction of the needle tip under the action of magnetic force or elastic force; when the active member is in the initial position, the blocking part is connected to the working part one, restricting the working part one from driving the needle to perform the puncture action; when the active member moves from the initial position to the release position along the first direction, the blocking part is disconnected from the working part one, and the working part one drives the needle to perform the puncture action.

[0005] During manufacturing, an interaction force is pre-set between working part 2 and working part 1. Working part 1 can drive the needle to move along the needle tip axis by the interaction force between it and working part 2 to perform the piercing action. When not in use, the active component restricts working part 1 from driving the needle to perform the piercing action until the user drives the active component in the first direction, thereby releasing working part 1. Working part 1 drives the needle tip to pierce the drug carrier at a preset speed. Subsequently, the needle performs the needle retraction action, and a hole is formed on the outer shell of the drug carrier for the drug to leave. During this process, when the operator performs the piercing action, their role is only to release working part one, causing it to drive the needle tip. The force and speed with which the operator drives the active component do not affect the needle tip and have no impact on its speed. The piercing speed of the needle tip depends on the pre-set force between working part one and working part two during manufacturing. Therefore, the manufacturer can adjust the force between working part one and working part two by considering factors such as the manufacturing material and thickness of the drug carrier shell, thereby adjusting the pre-set insertion force on the needle tip to ensure that the needle tip can pierce the drug carrier shell at an appropriate speed and force. Working part two and working part one are elastically coupled through springs, rubber blocks, or other elastic components, or through magnetic attraction between magnets, or through magnetic coupling between magnets and magnetic components that can attract each other. This ensures that working part one and working part two have a pre-set force during manufacturing, resulting in a simple, reliable, and easy-to-produce structure.

[0006] In one embodiment of this application, a working part one is disposed between a working part two and a drug chamber; the needle insertion unit includes a needle insertion elastic member, the working part one is provided with one end of the needle insertion elastic member, the working part two is provided with the other end of the needle insertion elastic member, when the active member is in the initial position, the needle insertion elastic member is in a state of compression and elastic deformation, and in the axial direction of the needle tip, the working part one tends to move away from the working part two and tends to move closer to the drug chamber along the axial direction of the needle tip.

[0007] In one embodiment of this application, the second working part is located between the first working part and the drug chamber; the needle insertion unit includes a needle insertion elastic member, the first working part is provided with one end of the needle insertion elastic member, the second working part is provided with the other end of the needle insertion elastic member, when the active member is in the initial position, the needle insertion elastic member is in a state of being stretched and undergoing elastic deformation, and in the axial direction of the needle tip, the first working part tends to move closer to the second working part, and tends to move closer to the drug chamber along the axial direction of the needle tip.

[0008] In one embodiment of this application, a working part one is disposed between a working part two and a drug reservoir along the axial direction of the needle tip; the needle insertion unit includes two magnets, which have a repulsive force between like poles; the working part one is provided with one magnet, and the working part two is provided with the other magnet; the working part two has a magnetic repulsive force on the working part one along the axial direction of the needle tip towards the drug reservoir, so that the working part one tends to move towards the drug reservoir along the axial direction of the needle tip.

[0009] By using magnetic repulsion to drive the needle to perform the puncture action, the distance between working part one and working part two can be reduced, thus saving space in the inhaler while obtaining a larger magnetic repulsion force to drive the needle movement and ensuring the puncture effect.

[0010] In one embodiment of this application, the rapid puncture inhaler further includes a third working part, which is equipped with a magnet. A first working part is fixed to the needle, a second working part is fixed to the active member, and a third working part is fixed to the main body. The third working part, the first working part, and the second working part are arranged sequentially along the axial direction away from the drug reservoir at the needle tip. The first working part and the second and third working parts have a repulsive force of like charges. When the active member moves along the first direction to the release position, the magnetic repulsion force of the second working part on the first working part is greater than that of the third working part on the first working part. The second working part drives the needle to perform a puncture action through the first working part, reducing the magnetic repulsion force of the second working part on the first working part and increasing the magnetic repulsion force of the third working part on the first working part. When the active member moves along the first direction from the release position to the needle retraction position, the magnetic repulsion force of the second working part on the first working part is less than that of the third working part on the first working part. The third working part drives the needle to perform a needle retraction action through the first working part.

[0011] In one embodiment of this application, the second working part is connected to the needle and is movably disposed relative to the needle tip in the axial direction, and fixedly disposed relative to the needle in the straight line direction of the first direction. The second working part is detachably connected to the active member, and the active member is movably disposed relative to the second working part in the first direction. The rapid puncture inhaler also includes a third working part fixedly disposed on the main body, and a magnet is provided at the third working part. The third working part, the first working part, and the second working part are arranged sequentially along the axial direction of the needle tip away from the drug tank, and the first working part is homogeneous with the second and third working parts. Repulsive action; when the driving member moves to the release position along the first direction, the magnetic repulsion force of the second working part on the first working part is greater than that of the third working part on the first working part. The second working part drives the needle to perform the puncture action through the first working part. The magnetic repulsion force of the second working part on the first working part decreases, and the magnetic repulsion force of the third working part on the first working part increases. When the driving member moves from the release position to the retraction position along the first direction, the second working part separates from the driving member. The driving member no longer provides the second working part with a force along the axial direction of the needle tip towards the drug chamber. The third working part drives the needle to perform the retraction action through the first working part.

[0012] By using magnetic repulsion to drive the needle to perform the puncture action and withdraw the needle, space can be saved in the inhaler while obtaining a large magnetic repulsion force to drive the needle movement, ensuring the puncture effect.

[0013] In one embodiment of this application, the second working part is connected to the needle and is movably disposed relative to the needle tip in the axial direction, and fixedly disposed relative to the needle in the straight line direction of the first direction. The second working part is detachably connected to the active member, and the active member is movably disposed relative to the second working part in the first direction. The rapid puncture inhaler also includes a needle retraction magnetic member fixedly disposed on the main body. The first working part, the second working part, and the needle retraction magnetic member are arranged sequentially in the direction away from the drug chamber along the axial direction of the needle tip. The first working part and the second working part have a like-pole repulsion effect, and the needle retraction magnetic member has a magnetic attraction effect on the second working part. The part of the needle located between the second working part and the needle retraction magnetic member is also provided with a driving part. When the active member is in the initial position, the driving part is spaced apart from the second working part. When the active member moves to the release position in the first direction, the second working part drives the needle to perform the puncture action through the first working part. When the active component moves from the release position to the needle retraction position along the first direction, the working part 2 separates from the active component. The active component no longer provides the working part 2 with a force that moves towards the drug chamber along the axial direction of the needle tip. The needle retraction magnetic component pulls the working part 2 closer by magnetic attraction, and the working part 2 drives the needle to perform the needle retraction action by the driving part.

[0014] In one embodiment of this application, the rapid-puncture inhaler further includes a needle-retracting magnetic attractor fixedly disposed with the main body and capable of magnetically attracting the first working part; the second working part is fixedly connected to the active member and is disposed between the first working part and the needle-retracting magnetic attractor; the needle-retracting magnetic attractor has a magnetic attraction force on the first working part along the axial direction of the needle tip away from the drug reservoir; when the active member moves to the release position along the first direction, the magnetic repulsion force of the second working part on the first working part is greater than the magnetic attraction force of the needle-retracting magnetic attractor on the first working part, and the second working part drives the needle to perform a puncture action through the first working part. When the active member moves from the release position to the needle-retracting position along the first direction, the magnetic repulsion force of the second working part on the first working part is less than the magnetic attraction force of the needle-retracting magnetic attractor on the first working part, and the needle-retracting magnetic attractor drives the needle to perform a needle-retracting action through the first working part.

[0015] In one embodiment of this application, working part two is located between working part one and drug reservoir in the axial direction of the needle tip; the needle insertion unit includes a magnet and a needle insertion magnetic suction member that can magnetically attract the needle insertion magnet. One of working part one and working part two is provided with a magnet, and the other is provided with a needle insertion magnetic suction member. Working part two has a magnetic attraction force on working part one that moves towards the drug reservoir in the axial direction of the needle tip, so that working part one tends to move towards the drug reservoir in the axial direction of the needle tip.

[0016] By using magnetic attraction to drive the needle to perform the puncture action, the distance between working part one and working part two can be reduced, saving space in the inhaler while obtaining a larger magnetic attraction to drive the needle movement, thus ensuring the puncture effect.

[0017] In one embodiment of this application, the rapid-puncture inhaler further includes a needle-retracting magnetic chuck. Working section two, working section one, and the needle-retracting magnetic chuck are sequentially arranged along the axial direction of the needle tip away from the drug reservoir. Working section one and the needle-retracting magnetic chuck have a magnetic attraction. Working section one is fixedly connected to the needle, working section two is fixedly connected to the driving member, and the needle-retracting magnetic chuck is fixedly connected to the main body. When the driving member moves along the first direction to the release position, the magnetic attraction of working section two on working section one is greater than the magnetic attraction of the needle-retracting magnetic chuck on working section one. Working section two drives the needle to perform a puncture action through working section one. When the driving member moves along the first direction from the release position to the needle-retracting position, the magnetic attraction of working section two on working section one is less than the magnetic attraction of the needle-retracting magnetic chuck on working section one. The needle-retracting magnetic chuck drives the needle to perform a needle-retracting action through working section one.

[0018] In one embodiment of this application, the rapid-piercing inhaler further includes a needle-retracting magnetic suction component. Working part two, working part one, and the needle-retracting magnetic suction component are sequentially arranged along the axial direction of the needle tip away from the drug reservoir. Working part one and the needle-retracting magnetic suction component have magnetic attraction. Working part one is fixedly connected to the needle, and the needle-retracting magnetic suction component is fixedly connected to the main body. Working part two is connected to the needle and is movable relative to the needle tip axially, and fixedly arranged relative to the needle in the straight line direction of the first direction. Working part two is detachably connected to the active component, and the active component... The working part is moved relative to the second working part in the first direction. When the active member moves to the release position in the first direction, the magnetic attraction force of the second working part on the first working part is greater than the magnetic attraction force of the needle retraction magnetic member on the first working part. The second working part drives the needle to perform the puncture action through the first working part. When the active member moves from the release position to the needle retraction position in the first direction, the second working part separates from the active member. The active member no longer provides the second working part with a force that moves towards the drug chamber along the needle tip axial direction. The needle retraction magnetic member pulls the first working part closer by magnetic attraction, so that the needle performs the needle retraction action.

[0019] By using magnetic attraction to drive the needle to perform the puncture and retraction actions, a large magnetic attraction force can be obtained to drive the needle movement while saving space in the inhaler, thus ensuring the puncture effect.

Furthermore, the active component is moved relative to the working part 2 in the first direction; when the active component moves to the release position in the first direction, the working part 2 attracts the working part 1 closer by magnetic attraction, and the working part 1 drives the needle to perform the puncture action; when the active component moves from the release position to the retraction position in the first direction, the working part 2 separates from the active component, and the active component no longer provides the working part 2 with a force along the needle tip axis towards the drug chamber, and the working part 3 pushes the working part 2 along the needle in the direction away from the drug chamber in the needle tip axis by magnetic repulsion, and the working part 2 drives the needle to perform the retraction action.

When the driving member moves from the release position to the needle retraction position in the first direction, the working part two separates from the driving member, and the driving member no longer provides the working part two with a force along the axial direction of the needle tip towards the drug reservoir. The needle retracts under the action of gravity.

[0037] The movement setting of one component relative to another component in this application refers to the relative sliding between the two components according to a preset path, or, according to a preset path, one component moves relative to another component by means of the rolling of a rolling element.

[0038] Please see Figures 1 to 25 Learn more about this application.

[0039] See Figure 1 The rapid puncture inhaler includes a needle 201 and a body 101.

[0040] The main body 101 is provided with a drug compartment 102 for holding a drug carrier and a suction nozzle 401 communicating with the drug compartment 102. The drug carrier can be a capsule or vesicle containing a vaccine or other drug, or other forms of carrier.

[0041] The medication in the medication carrier can enter the medication chamber 102 through a hole pierced in the medication carrier by the needle 201. The user can inhale the medication that enters the medication chamber 102 from the medication carrier through the mouthpiece 401. The inhaler is equipped with an air intake duct 108 connecting the medication chamber 102 to the outside. The mouthpiece 401 is connected to the medication chamber 102. When the user inhales the medication in the medication chamber 102 through the mouthpiece 401, a negative pressure is generated at the mouthpiece 401. Outside air enters the medication chamber 102 through the air intake duct 108. Under the impact of the high-speed airflow, the powder in the medication carrier enters the medication chamber 102. The airflow carries the medication in the medication chamber 102 to the mouthpiece 401, where the medication enters the user's body along with the airflow.

[0042] The needle 201 has a needle tip 202 for piercing the drug carrier. The needle 201 is slidably or rollably connected to the body 101, and the needle 201 is axially disposed on the body 101 along the needle tip 202. See also Figure 1The needle 201 has a needle tip 202, and the medicine chamber 102 has a connecting hole 103 parallel to the axial direction of the needle tip 202. The inner diameter of the connecting hole 103 is not less than the outer diameter of the needle tip 202. The two needle tips 202 are respectively inserted into the two connecting holes 103 and are slidably connected with the connecting holes 103. Of course, a rotatable rolling body can also be provided between the side wall of the connecting hole 103 and the needle tip 202 to reduce the friction between the needle tip 202 and the side wall of the connecting hole 103. For example, a linear bearing can be provided between the side wall of the connecting hole 103 and the needle tip 202. The needle tip 202 can pass through the linear bearing and move relative to the connecting hole 103 in the axial direction of the needle tip 202, thereby realizing the movement of the needle 201 relative to the main body 101 in the axial direction of the needle tip 202. During this process, the sidewall of the connecting hole 103 guides the movement of the needle tip 202. Of course, those skilled in the art to which this application pertains will understand that other connection methods can be used to realize the movement of the needle 201 relative to the main body 101 in the axial direction of the needle tip 202. For example, the needle 201 is provided with a needle tip 202 and a needle rod 204. The needle tip 202 is located at one end of the needle rod 204, and the other end of the needle rod 204 is inserted into the guide hole of the main body 101 and slidably connected with the guide hole. The needle rod 204 can reciprocate along the axis of the guide hole in the axial direction of the needle tip 202 so that the needle 201 has the stroke to perform the piercing action and the needle withdrawal action. Of course, those skilled in the art to which this application pertains will understand that the embodiment in which the needle 201 is axially movable on the main body 101 along the needle tip 202 can also have other forms, such as a slider on the side wall of the needle rod 204, and a groove in the main body 101 that cooperates with the slider along the axial direction of the needle tip 202. The needle 201 is connected to the main body 101 through a slider-groove guide rail structure composed of the slider and the groove. Through the above-described connecting hole 103, guide hole, and groove structure on the main body 101, the needle 201 performing the piercing action or the needle retraction action can be guided so that the needle 201 moves in a preset direction and path. Of course, there are other implementation methods to connect the needle 201 and the main body 101. The needle 201 moves axially relative to the main body 101 at the needle tip 202 to perform piercing and retraction actions. These will not be elaborated here. The needle 201 can move axially relative to the main body 101 along the needle tip 202, and the needle tip 202 of the needle 201 can perform piercing and retraction actions.

[0043] Those skilled in the art to which this application pertains will understand that the number of needle tips 202 provided on a single needle 201 in this application can be set as follows: Figure 1As shown, the main body 101 has two connecting holes 103 corresponding to the two needle tips 202, so that the two needle tips 202 can enter the medicine container 102 through the two connecting holes 103 respectively. Through the piercing action and the retraction action of the needle 201, two holes are formed on the medicine carrier for the medicine to leave the medicine carrier. Of course, the number of needle tips 202 is not limited to two, but can also be one, three or other numbers, which can be set according to the actual use requirements. The main body 101 has connecting holes 103 that match the number of needle tips 202 and are connected to the medicine container 102.

[0044] The needle tip 202 of the needle 201 can move along the axial direction of the needle tip 202 toward the drug chamber 102. The needle tip 202 enters the drug chamber 102 through the connecting hole 103, pierces the drug carrier in the drug chamber 102, and performs a piercing action. Then, the needle tip 202 moves along its axial direction away from the drug chamber 102, the needle 201 performs a needle withdrawal action, the needle tip 202 exits the drug carrier, and a hole is formed on the outer shell of the drug carrier for the drug to leave the drug carrier.

[0045] Preferably, when the inhaler is not in use, the needle tip 202 is completely not inserted into the medication compartment 102. This prevents the medication carrier from being prematurely punctured and leaking or becoming unusable due to bumps or other factors during transport. Of course, when the user inhales the medication powder, the needle tip 202 should also be completely withdrawn from the medication compartment 102 through the connecting hole 103 during the needle withdrawal action. This prevents motion interference between the needle tip 202 and the medication carrier, which is vibrating due to airflow, thus avoiding excessive medication powder remaining on the carrier.

[0046] To reduce the impact of human factors on the puncture effect and ensure the puncture effect, the needle tip 202 is pre-set at the speed and force when puncturing the drug carrier shell during manufacturing, based on factors such as the material and thickness of the drug carrier shell, to ensure that the needle tip 202 can successfully puncture the drug carrier shell.

[0047] See Figure 1 , Figure 2 The rapid puncture inhaler also includes a needle insertion unit and an active element 301 that is movable along a first direction and disposed on the main body 101.

[0048] The needle insertion unit includes a working part 501 connected to the needle 201 and a working part 502 connected to the main body 101 or the active component 301. The working part 502 is elastically coupled or magnetically coupled to the working part 501. The working part 502 and the working part 501 are elastically coupled through elastic components such as springs and rubber blocks, or through magnetic attraction between magnets, or through a magnet and a magnetic component that can magnetically attract the magnet. When the inhaler leaves the factory, the working part 501 and the working part 502 are pre-set with elasticity or magnetic force. Under the action of elasticity or magnetic force, the working part 501 has a tendency to move towards the drug chamber 102 along the axial direction of the needle tip 202. The working part 501 can drive the needle 201 to move in the direction of moving towards the drug chamber 102 along the axial direction of the needle tip 202, thereby causing the needle 201 to perform a piercing action.

[0049] If the needle tip 202 pierces the outer shell of the drug carrier too slowly, it will increase the squeezing effect of the needle tip 202 on the outer shell of the drug carrier, causing the outer shell of the drug carrier to undergo large deformation. If the outer shell of the drug carrier deforms too much during the piercing process of the needle tip 202, when the airflow drives the drug carrier to move and release the drug, the shape of the outer shell of the drug carrier will no longer match the internal shape of the drug chamber 102, affecting the rotation effect of the drug carrier. Furthermore, the change in the shape of the outer shell of the drug carrier will also change its aerodynamic effect, affecting the movement of the drug carrier within the drug chamber 102, and thus affecting the release of the drug. Manufacturers can adjust the force between working part 1 501 and working part 2 502 by adjusting parameters such as the manufacturing material and thickness of the drug carrier shell. This allows them to adjust the piercing force and speed when working part 1 501 drives the needle tip 202 to pierce the drug carrier shell, ensuring that the needle tip 202 can pierce the drug carrier shell at an appropriate speed and force. It also reduces the degree of deformation of the drug carrier shell caused by the needle tip 202 piercing the drug carrier, ensuring that the needle tip 202 can successfully pierce the drug carrier shell while reducing the degree of deformation of the drug carrier shell, thus ensuring the smooth release of the drug and reducing drug residue in the drug carrier.

[0050] In order for the working part 501 to drive the needle 201 to move only when the user uses the inhaler, this application provides an active member 301 on the main body 101 that can move along a first direction. When the active member 301 is in the initial position, the blocking part 302 provided on the active member 301 is connected to the working part 501, preventing the working part 501 from approaching the drug tank 102 along the axial direction of the needle tip 202, thus limiting the working part 501 from driving the needle 201 to perform the puncture action. When the active member 301 moves from the initial position to the release position along the first direction, the blocking part 302 is disconnected from the working part 501, and the blocking part 302 of the active member 301 stops limiting the movement of the working part 501 towards the drug tank 102 along the axial direction of the needle tip 202. The working part 501 will then drive the needle 201 to perform the puncture action. The first direction can be a straight line perpendicular to the axial direction of the needle tip 202, or it can be the direction in which the rotating component rotates around a rotation axis, with the rotation axis of the first direction being parallel to the axial direction of the needle tip 202.

[0051] During the process of the needle tip 202 piercing the outer shell of the drug carrier, the user does not need to resist the resistance given to the needle 201 by the drug carrier when the needle 201 pierces the drug carrier, nor does the user need to resist the resistance given by the spring or other elastic components when the button is pressed. The user only needs to release the working part 501 through the active part 301 to achieve the piercing of the capsule, which is more labor-saving and convenient for users with weak strength.

[0052] When the needle 201 performs the puncture action, a limiting structure can be set along the movement path of the needle 201 to prevent the needle 201 from excessively entering the medicine tank 102. For example, see Figure 1 There is a solid structure between the two connecting holes 103. When the needle 201 approaches the medicine chamber 102 under the action of the working part 501, and the needle 201 performs the piercing action, the limiting structure gets stuck between the two needle tips 202, preventing the working part 501 from continuing to drive the needle tips 202 into the medicine chamber 102, thus limiting the movement of the needle tips 202. Of course, other limiting structures can also be used to prevent the needle tips 202 from excessively piercing the medicine carrier. For example, a first limiting part 203 that cannot pass through the connecting hole 103 can be used as a limiting structure to prevent the needle tips 202 from excessively extending into the medicine chamber. Of course, there are other methods, which will not be described in detail here.

[0053] The following section details the process of the puncture and withdrawal of the needle 201.

[0054] First, an embodiment in which the working part 1 501 and the working part 2 502 are elastically coupled in a straight line direction perpendicular to the axial direction of the needle tip 202, so that the working part 1 501 tends to move closer to the medicine tank 102 along the axial direction of the needle tip 202, will be described.

[0055] See Figure 1 The needle insertion unit includes a first working part 501 and a second working part 502, and a needle insertion elastic element disposed between the first working part 501 and the second working part 502. The needle insertion unit includes the needle insertion elastic element; one end of the needle insertion elastic element is located in the first working part 501, and the other end is located in the second working part 502. The needle insertion elastic element is a compression-type elastic element 610. Figure 1 The compression elastic element 610 shown is the needle insertion spring 601. Of course, spring sheets, rubber blocks, or other compression elastic elements 610 can also be used instead of the needle insertion spring 601 as the needle insertion elastic element, which will not be elaborated here. The following describes the structure of the inhaler when the needle insertion elastic element is a compression elastic element 610, taking it as an example.

[0056] See Figure 1 , Figure 2 The needle 201 has a needle rod 204 and a needle tip 202, with the axial direction of the needle rod 204 parallel to the axial direction of the needle tip 202. The driving member 301 has a driving mounting part 303, on which a guide channel 305 is provided along the straight direction of the first direction. The needle rod 204 passes through the guide channel 305 and can move axially relative to the guide channel 305 in the needle tip direction. When the needle 201 performs a piercing or retraction action, the needle rod 204 moves axially relative to the driving mounting part 303 in the needle tip direction. Since the needle 201 only moves axially relative to the main body 101 in the needle tip direction, while the driving member 301 needs to move in the first direction perpendicular to the needle tip direction, the driving member 301 will move relative to the needle rod 204 in the first direction. (See [reference]). Figure 1 The guide channel 305 extends along the straight line direction of the first direction. When the active member 301 moves along the first direction, the guide channel 305 can move relative to the needle 201 in the first direction. Setting the guide channel 305 can avoid motion interference between the active member 301 and the needle 201 caused by the physical structure.

[0057] See Figure 2The inner diameter of the needle spring 601 is not less than the outer diameter of the needle rod 204, and the needle spring 601 is sleeved on the needle rod 204. One end of the needle spring 601 can be regarded as working part one 501, and the other end as working part two 502. Working part two 502 abuts against the active mounting part 303 of the active member 301. The needle spring 601 is located between the first limiting part 203 and the active mounting part 303, and working part one 501 abuts against the first limiting part 203 provided on the needle rod 204. The distance between the first limiting part 203 and the active mounting part 303 in the axial direction of the needle tip is less than the length of the needle spring 601 in its natural state, so the needle spring 601 is in a compressed state and undergoes elastic deformation. Under the elastic action of the needle spring 601, working part one 501 and working part two 502 tend to move away from each other in the axial direction of the needle tip. The active component 301 can only move relative to the main body 101 in the first direction and cannot move in the axial direction of the needle tip. The position of the second working part 502, which abuts against the active mounting part 303, cannot change in the axial direction of the needle tip; only the first working part 501 changes in the axial direction of the needle tip, moving away from the second working part 502. The first working part 501 is located between the medicine tank 102 and the second working part 502, thus the first working part 501 tends to move closer to the medicine tank 102 along the axial direction of the needle tip. The first working part 501 abuts against the first limiting part 203 provided on the needle 201, thus the first working part 501 tends to drive the needle 201 to perform a piercing action. See also... Figure 2 When the active member 301 is in the initial position, the needle insertion elastic member is compressed and undergoes elastic deformation. In the axial direction of the needle tip 202, the first working part 501 tends to move away from the second working part 502 and towards the drug reservoir 102 along the axial direction of the needle tip 202. The first working part 501 applies a thrust via the first limiting part 203 in the direction of approaching the drug reservoir 102 along the axial direction of the needle tip, causing the needle 201 to tend to perform a puncture action.

[0058] To ensure that the needle tip 202 only performs the puncture action when the user is using the inhaler, see [reference needed]. Figure 2 The active component 301, which can only move in the straight line direction of the first direction, is also provided with a blocking part 302. The blocking part 302 and the working part 501 respectively abut against the first limiting part 203 on both sides along the axial direction of the needle tip. The blocking part 302 is located between the first limiting part 203 and the drug chamber 102, and is indirectly connected to the working part 501 through the first limiting part 203. The blocking part 302 prevents the working part 501 from approaching the drug chamber and prevents the needle 201 from approaching the drug chamber 102 along the axial direction of the needle tip, thereby preventing the needle 201 from performing a piercing action. As a result, the needle spring 601 is in a compressed state before the inhaler is used, storing a certain amount of elastic potential energy.

[0059] See Figure 3 , Figure 4 When the needle 201 needs to perform a piercing action, the driving member 301 moves in the first direction, and the blocking part 302 moves in the first direction relative to the first limiting part 203. When the driving member 301 reaches the release position, the blocking part 302 leaves the first limiting part 203. The blocking part 302 no longer abuts against the side of the first limiting part 203 near the medicine tank 102. The blocking part 302 no longer restricts the working part 501 from approaching the medicine tank 102 along the needle tip axis through the first limiting part 203. Thus, the needle 201 performs a piercing action under the drive of the working part 501. During this process, since the working part 2 502 is fitted onto the needle rod 204 of the needle 201 and connected to the active mounting part 303 of the active member 301, when the working part 1 501 drives the needle 201 to perform the piercing action, even if the active member 301 moves along the first direction and the needle 201 moves along the needle tip axial direction, the position of the working part 2 502 relative to the drug tank is fixed, which will be explained below.

[0060] See Figure 3Since the needle insertion spring 601 is sleeved on the needle rod 204, the needle 201 and the working part 2 502 are fixedly arranged in the straight line direction of the first direction. The needle rod 204 can slide relative to the needle insertion spring 601 in the axial direction of the needle tip 202. The needle 201 is moved relative to the working part 2 502 in the axial direction of the needle tip, and can perform puncture and needle withdrawal actions. As the active member 301 moves relative to the main body 101 along the first direction, from the initial position to the release position, since the needle insertion spring 601 is sleeved on the needle rod 204, when the active member 301 moves relative to the main body 101 and the needle 201 along the first direction, the active member 301 will also move relative to the working part 502 sleeved on the needle rod 204 along the first direction. The working part 502, which abuts against the active mounting part 303, slides relative to the active mounting part 303. Therefore, the active member 301 with the active mounting part 303 moves relative to the working part 502 in the straight line direction of the first direction. When the working part 2 502 is connected to the active mounting part 303, and the working part 1 501 drives the needle 201 to perform the piercing action, the active mounting part 303 provides a force to the working part 2 502 along the axial direction of the needle tip, moving it closer to the medicine tank 102. The active mounting part 303 acts as a fulcrum for the working part 2 502, preventing it from moving away from the medicine tank 102 along the axial direction of the needle tip, thus keeping the distance between the working part 2 502 and the medicine tank 102 in the axial direction of the needle tip constant. The active mounting part 303 supports the needle insertion spring 601 through the working part 2 502, while the working part... When the needle 201 moves along the needle tip axial direction toward the drug chamber 102, the active mounting part 303 supports the needle 201 through the working part 2 502, the needle insertion spring 601, and the working part 1 501. The working part 2 502 applies a reaction force to the active mounting part 303 along the needle tip axial direction away from the drug chamber 102, so that the working part 2 502 abuts against the active mounting part 303, thereby connecting the working part 2 502 and the active mounting part 303. When the needle 201 performs the piercing action, the position of the working part 2 502 relative to the active mounting part 303 is fixed in the needle tip axial direction.The working part 502 and the active mounting part 303 can slide relative to each other. The needle insertion spring 601 is sleeved on the needle rod 204, and the needle rod 204 limits the needle insertion spring 601, so that the needle 201 and the needle insertion spring 601 are relatively fixed in the first direction and will not move relative to each other. Thus, the working part 502 is fixed relative to the needle 201 in the first direction and does not move with the active member 301 in the first direction. The needle insertion spring 601 is always sleeved on the needle rod 204. 01. Working part 1 501 and working part 2 502 will not move relative to the needle 201 in the first direction. Therefore, during the puncture action of the needle 201, the active mounting part 303 always acts as a fulcrum. Through the elastic deformation of the needle insertion spring 601, working part 2 502 can apply a force to working part 1 501 along the needle tip axial direction and close to the drug chamber 102. The needle rod 204 guides the length change of the needle insertion spring 601, so that the needle insertion spring 601 can only change length in the needle tip axial direction. For example, when the axial direction of the needle tip 202 is parallel to the vertical direction and the first direction is parallel to the horizontal direction, and the needle insertion spring 601 is sleeved on the needle rod 204 of the needle 201, when the working part 1 501 moves upward and drives the needle 201 to perform the piercing action, the needle 201 moves axially relative to the working part 2 502 in the needle tip 202 direction, so that the needle 201 is moved relative to the working part 2 502 in the needle tip axial direction and is fixed relative to the working part 2 502 in the first direction. The active mounting part 303 provides a fulcrum to the working part 2 502, preventing the needle spring 601 from falling due to its own weight and the weight of the needle 201. This allows the working part 1 501 to move stably upward through the elastic action of the needle spring 601, driving the needle tip 202 to perform the piercing action upward. At the same time, the needle spring 601 sleeved on the needle rod 204 will not move with the movement of the active mounting part 303 of the active member 301. The active mounting part 303 slides relative to the working part 2 502 in the first direction. The active mounting part 303 is moved relative to the working part 2 502 in the straight line direction of the first direction.

[0061] Those skilled in the art will understand that the connection between the working part 501 and the needle 201 in this application is not limited to the method described above where the working part 501 abuts against the first limiting part 203. It can also be that the working part 501 is fixedly connected to other positions of the needle rod 204, not located at the first limiting part 203. Alternatively, the working part 501 can be a collar sleeved on the needle rod 204 and capable of sliding along it. When the driving member 301 is in its initial position, the working part 501 and the first limiting part 203 are spaced apart. The blocking part 302 is located between the working part 501 and the medicine chamber 102, and directly abuts against the side of the working part 501 closest to the medicine chamber 102. 2. Directly abutting against the working part 501, the blocking part 302 prevents the working part 501 from moving away from the working part 502; when the driving member 301 moves from the initial position to the release position, the blocking part 302 slides relative to the working part 501 until the blocking part 302 disconnects from the abutting connection with the working part 501, stopping the restriction on the movement of the working part 501. The working part 501 moves along the needle tip axis towards the drug chamber 102. After moving a certain distance, the working part 501 reaches the first limiting part 203. Then the working part 501 abuts against the first limiting part 203 and pushes the needle 201 by pushing the first limiting part 203, so that the needle tip 202 of the needle 201 performs the piercing action.

[0062] When the working part one drives the needle to perform the puncture action, the position of the second working part relative to the drug reservoir is fixed, so that the force line of the second working part on the first working part is parallel to the axial direction of the needle tip, thereby enabling the first working part to better drive the needle to perform the puncture action. Preferably, the force exerted by the second working part on the first working part is coaxial with the axis of the needle rod.

[0063] Those skilled in the art will understand that the connection between the blocking part 302 and the working part 501 in this application can be either as described above (the blocking part 302 is indirectly connected to the working part 501 through the first limiting part 203), or as described above (the blocking part 302 is directly and detachably connected to the working part 501). When the active member 301 is in the initial position, the blocking part 302 can directly or indirectly prevent the working part 501 from approaching the drug chamber.

[0064] The method by which the blocking part 302 can be detachably connected to the first limiting part 203 or the working part 501 to restrict the movement of the working part 501 is not limited to the method described above where the blocking part 302 abuts against the first limiting part 203 or the working part 501. It can also be, for example, where the first limiting part 203 or the working part 501 and the blocking part 302 are inserted into each other. The first limiting part 203 or the working part 501 has an insertion hole along a first direction, and the blocking part 302 has an insertion rod along the first direction. When the driving member 301 is in the initial position, the insertion... When the rod is inserted into the insertion hole, the active member 301 restricts the movement of the needle 201. When the active member 301 is in the release position, the rod is completely removed from the insertion hole, and the active member 301 no longer restricts the working part 501. The working part 501 can drive the needle 201 to perform the piercing action. Of course, the separable connection between the blocking part 302 and the first limiting part 203 or the working part 501 can also be achieved in other ways, which will not be elaborated here. As long as the blocking part 302 can prevent or release the working part 501 from moving along the needle tip axis toward the medicine tank 102.

[0065] This application can achieve the retraction of the needle 201 through various forces, as detailed below.

[0066] See Figure 3 The needle 201 can retract under the influence of gravity. The drug chamber 102, needle 201, and actuator 301 are arranged vertically, with the needle 201 located below the drug chamber 102. When the inhaler is in use, the actuator 301 is horizontally positioned, the needle tip 202 is vertically positioned axially, and horizontally positioned in the first direction. The needle insertion spring 601 is sleeved on the needle rod 204 and is located between the drug chamber 102 and the actuator 301. The first working part 501 has a distance from the second working part 502 and applies an upward insertion force to the needle 201, causing the needle 201 to tend to perform a piercing action. When the second working part 502 abuts against the active mounting part 303 on the actuator 301, the active mounting part 303 of the actuator 301 acts as a fulcrum for the second working part 502, providing support for the needle insertion spring 601. When the active component 301 moves relative to the main body 101 in the first direction to the release position, the working part 1 501 moves away from the working part 2 502 along the axial direction of the needle tip, and the working part 1 501 drives the needle 201 to perform the piercing action. After the needle 201 performs the piercing action, see [link to previous section]. Figure 1 The end of the guide channel 305 provided in the active mounting part 303 of the active component 301 is connected to the outside, and the needle rod 204 can leave the guide channel 305 through this opening. See also Figure 1 , Figure 4As the active member 301 moves along the first direction, the needle rod 204 gradually moves towards the end of the guide channel 305 until the active member 301 moves from the release position to the retraction position. The needle rod 204 then leaves the guide channel 305 through the end opening, separating from the active member 301. Simultaneously, the needle insertion spring 601, sleeved on the needle rod 204, no longer abuts against the active mounting part 303 of the active member 301 due to the change in the position of the active member 301. The working part 2 502 separates from the active mounting part 303, and the active mounting part 303 no longer provides upward support to the needle insertion spring 601 through the working part 2 502 (the active member 301 no longer provides a force along the needle tip 202 axially towards the drug reservoir 102 to the working part 2 502). The active mounting part 301's active mounting... The device 303 no longer provides support to the needle 201 through the working part 2 502, the needle insertion spring 601, and the working part 1 501. Therefore, under the action of its own weight, the needle 201 can move downward, the needle tip 202 exits the drug carrier, the needle 201 performs the needle withdrawal action, and a hole is formed on the outer shell of the drug carrier in the drug chamber 102. The drug can leave the drug carrier through the hole and enter the drug chamber 102. The drug is then carried into the human body by the high-speed airflow of the drug chamber 102.

[0067] Of course, it can also be in the straight line direction of the first direction. The guide channel 305 of the active member 301 includes a narrow section and a wide section. When the active member 301 is in the initial position and the release position, the working part 502 abuts against the narrow section of the guide channel 305, and the working part 502 cannot fall down through the guide channel 305. Until the active member 301 moves to the needle retraction position along the first direction, the wide section of the guide channel 305 moves to the working part 502. At this time, the width of the guide channel 305 is greater than the diameter of the working part 502 and the needle insertion spring 601, and the working part 502 can fall down through the guide channel 305. The active mounting part 303 can no longer support the working part 502, and the active mounting part 303 stops providing support to the needle insertion spring 601 and the needle 201. The needle insertion spring 601 and the needle 201 separate from the active member 301, and the needle 201 falls under the action of gravity, and the needle 201 performs the needle retraction action.

[0068] Preferably, the working part 501 is fixedly connected to the needle rod 204. When the needle rod 204 leaves the guide channel 305 of the driving member 301, and the working part 502 no longer abuts against the driving mounting part 303, the needle insertion spring 601 will exert a downward force on the needle 201 due to its own gravity. Combined with the downward gravity of the needle 201, this ensures that the needle tip 202 can move downward smoothly and perform the needle retraction action. Of course, a weight can also be fixedly connected to the needle rod 204 to increase the downward force applied to the needle 201 and ensure the normal operation of the needle retraction action.

[0069] Those skilled in the art to which this application pertains will understand that when the inhaler is in use, the active member 301 has not yet reached the needle retraction position along the first direction. The active member 301 has a limiting effect on the working part 2 502 in the axial direction of the needle tip. When the active member 301 provides support to the needle 201 through the working part 2 502, the needle insertion spring 601, and the working part 1 501, the upward elastic force of the needle insertion spring 601 needs to be greater than the downward force on the needle 201 to ensure that the working part 1 501 can drive the needle 201 to move upward and the needle 201 performs the puncture action.

[0070] See Figures 1 to 4In the above text, the compressed needle spring 601 is sleeved on the needle rod 204, with its two ends abutting against the first limiting part 203 and the active mounting part 303, respectively. When the active member 301 is in the released position, the second working part 502, which abuts against the active mounting part 303 of the active member 301, serves as the fulcrum for the extension of the needle spring 601, causing the needle spring 601 to extend. The first working part 501 moves closer to the drug reservoir 102 along the needle tip axial direction relative to the second working part 502. When the working part 501 drives the needle 201 to perform the piercing action, the needle rod 204 and the working part 502 sleeved on the needle rod 204 slide relative to each other. The working part 502 sleeved on the needle rod 204 and the needle 201 move relative to each other in the axial direction of the needle tip, and the working part 502 bears a force along the axial direction of the needle tip away from the drug tank 102, so that the working part 502 abuts against the active mounting part 303. Since the needle insertion spring 601 is sleeved on the needle rod 204, the needle insertion spring 601 cannot move relative to the needle rod 204 in the axial direction of the needle tip. The working part 502 is fixedly provided with one end of the needle insertion spring 601, so the working part 502 and the needle 201 are fixedly arranged relative to each other in the straight line direction of the first direction. When the driving member 301 moves from the initial position to the release position, the needle insertion spring 601 is in a compressed state. Both ends of the needle insertion spring 601 abut against the first limiting part 203 and the active mounting part 303 of the driving member 301, respectively. The working part 502 abuts against the active mounting part 303 under the elastic force of the needle insertion spring 601. Due to the movement of the driving member 301 along the first direction, the working part 502 experiences sliding friction with the active mounting part 303. The working part 502 and the active mounting part 303 of the driving member 301 move relative to each other in the linear direction of the first direction until the driving member 301 moves to the needle retraction position. The end of the active mounting part 303 passes through the working part 502, and the working part 502 disengages from the active mounting part 303, thus separating the working part 502 from the driving member 301. Those skilled in the art to which this application pertains will understand that the working part 2 502 may also be provided with a rolling element, and the working part 2 502 directly abuts against the active mounting part 303 through the rolling element, and can generate rolling friction with the active mounting part 303.

[0071] In this application, the second working part 502 is connected to the needle 201 and is movably disposed relative to the needle 201 in the axial direction of the needle tip 202, and is fixedly disposed relative to the needle 201 in the linear direction of the first direction. The second working part 502 is detachably connected to the driving member 301, and the driving member 301 is movably disposed relative to the second working part 502 in the first direction. Thus, when the needle 201 performs a piercing action, the way in which the position of the second working part 502 is fixed relative to the drug reservoir is not limited to the above-described method where the second working part 502 is sleeved on the needle rod 204, abuts against the driving mounting part 303, and can move relative to the driving mounting part 303 in the linear direction of the first direction; it can also be achieved in other ways. For example, see [link to relevant documentation]. Figure 5The first working part 501 is fixedly connected to the needle 201. The second working part 502 forms a guide rail slider system with the active mounting part 303 via the active slider 304. The second working part 502 is fixedly connected to the active slider 304, which has an opening through which the needle 201 passes along the axial direction of the needle tip. The active slider 304 is sleeved on the needle rod 204 of the needle 201. In this way, the second working part 502 is indirectly connected to the needle 201 through the active slider 304, and the needle 201 can move relative to the active slider 304 and the second working part 502 along the axial direction of the needle tip. The first working part 501 can drive the needle 201 to move relative to the second working part 502 along the axial direction of the needle tip relative to the connecting hole 103, performing the piercing action and the needle retraction action, thereby realizing the movement of the second working part 502 relative to the needle 201 in the axial direction of the needle tip. Since the working part 502 is fixedly connected to the active slider 304, and the active slider 304 is sleeved on the needle 201, the working part 502 cannot move relative to the needle 201 in the first direction. When the active member 301 moves in the first direction, the active slider 304 will not move with the active mounting part 303 in the first direction, but will remain at the needle 201, thus the working part 502 is fixedly set relative to the needle 201 in the straight line direction of the first direction. The active slider 304 is slidably connected to the active mounting part 303 or is rolledly connected to the active mounting part 303 by means of rolling elements, thus the active slider 304 and the active mounting part 303 form a guide rail slider system. The active slider 304 can only move along the active mounting part 303 and cannot move axially relative to the active mounting part 303 at the needle tip. The second working part 502 is fixedly connected to the active slider 304, thereby fixing the second working part 502, the active mounting part 303, and the active component 301 in the axial direction of the needle tip. The second working part 502, the active mounting part 303, and the active component 301 are movable relative to each other in the linear direction of the first direction. This continues until the active slider 304 disengages from the active mounting part 303 at its end, separating from it. At this point, the active mounting part 303 no longer restricts the movement of the second working part 502 through the active slider 304, and the active mounting part 303 no longer provides the second working part 502 with a force along the axial direction of the needle tip towards the drug tank 102 through the active slider 304. This allows the working part 502 and the needle 201 to be moved relative to each other in the axial direction of the needle tip, and to be fixed relative to each other in the straight line direction of the first direction. The working part 502 and the active mounting part 303 can be moved relative to each other in the straight line direction of the first direction, and to be fixed relative to each other in the axial direction of the needle tip. The working part 502 and the active mounting part 303 of the active member 301 can be detachably connected, so that when the working part 502 is simultaneously connected to the needle rod 204 and the active mounting part 303 of the active member 301, the position of the working part 502 relative to the drug tank 102 is fixed.

[0072] That is, by moving the active member 301 along the first direction, the needle rod 204 moves relative to the guide channel 305 within the guide channel 305, and the needle rod 204 has a limiting effect on the working part 2 502 in the axial direction perpendicular to the needle tip. The working part 2 502 is sleeved on the needle rod 204 and directly abuts against the active mounting part 303 on the side near the drug chamber along the needle tip axial direction. The interaction force between the working part 1 501 and the working part 2 502 causes the working part 2 502 to abut against the active mounting part 303 on the side near the drug chamber, thus limiting the working part 2 502 in the axial direction of the needle tip. Alternatively, the working part 2 502 is fixedly connected to the active slider 304, which forms a guide rail slider system with the active mounting part 303. The active mounting part 303 directly limits the working part 2 502 through the active slider 304, so that the working part 2 502 is limited in the axial direction perpendicular to the active mounting part 303. When connected, the second working part 502 can only move relative to the active mounting part 303 in the direction of the first direction, so that the second working part 502 and the needle 201 can be moved relative to each other in the axial direction of the needle tip and fixed relative to each other in the straight line direction of the first direction; the second working part 502 and the active member 301 can be moved relative to each other in the straight line direction of the first direction and fixed relative to each other in the axial direction of the needle tip; the second working part 502 and the active mounting part 303 of the active member 301 can be detachably connected, so that when the second working part 502 is simultaneously connected to the needle rod 204 and the active mounting part 303 of the active member 301, the position of the second working part 502 relative to the drug tank 102 is fixed.

[0073] In one embodiment of the active slider 304 and the active mounting part 303, see [link to relevant documentation]. Figure 1 , Figure 5The active slider 304 is movably positioned at the guide channel 305. When the active slider 304 is connected to the active mounting part 303, the active mounting part 303 limits the position of the active slider 304 in the axial direction of the needle tip, so that the distance between the active slider 304, the working part 2 502 and the medicine tank 102 in the axial direction of the needle tip is fixed until the active member 301 moves to the needle retraction position. The active slider 304 disengages from the active mounting part 303 through the end opening of the guide channel 305, thereby separating the active slider 304 from the active member 301. The active mounting part 303 of the active member 301 no longer limits the active slider 304 in the axial direction of the needle tip, and the distance between the active slider 304 and the medicine tank 102 in the axial direction of the needle tip can change. The needle 201 can perform the needle retraction action under the action of gravity. Of course, the active slider 304 may also be provided with a T-shaped guide groove that is slidably or rollingly connected to the active mounting part 303, and the active mounting part 303 may be provided with a T-shaped guide bar that cooperates with the T-shaped guide groove. The active slider 304 is connected to the active mounting part 303 through the T-shaped guide groove and the T-shaped guide bar. The active slider 304 can only move along the active mounting part 303 in the first direction and cannot move relative to the active mounting part 303 in the axial direction of the needle tip. This will not be elaborated further here.

[0074] The second working part 502 is movable relative to the needle 201 in the axial direction of the needle tip, and is fixed relative to it in the straight line direction of the first direction. The second working part 502 is movable relative to the active mounting part 303 in the straight line direction of the first direction, and is fixed relative to it in the axial direction of the needle tip. The second working part 502 is detachably connected to the active mounting part 303 of the active member 301. When the second working part 502 is simultaneously connected to the needle rod 204 and the active mounting part 303 of the active member 301, the position of the second working part 502 relative to the drug tank 102 is fixed, so as to stably apply a force along the axial direction of the needle tip towards the drug tank to the first working part 501, so that the first working part 501 stably drives the needle 201 to perform the piercing action. Preferably, the force applied by the second working part 502 to the first working part 501 along the axial direction of the needle tip towards the drug tank is coaxial with the needle 201, so as to better drive the needle 201 to perform the piercing action.

[0075] Those skilled in the art to which this application pertains will understand that the working part 502 in this application is fixedly disposed relative to the needle 201 in the first direction and moves relative to the needle 201 in the axial direction of the needle tip. This is not limited to the working part 502 being sleeved on the needle 201. Alternatively, the working part 502 can be fixedly connected to the active slider 304, with the active slider 304 sleeved on the needle 201. The working part 502 is not sleeved on the needle 201 but is disposed parallel to the needle 201. Multiple needle insertion springs or needle insertion tension springs are provided around the needle axis to achieve elastic or magnetic coupling between the working part 501 and the working part 502. This also allows the working part 502 to be fixedly disposed relative to the needle 201 in the first direction and move relative to the needle 201 in the axial direction of the needle tip.

[0076] Those skilled in the art to which this application pertains will understand that the separable connection between the working part 502 and the active member 301 can be achieved by, as described above, when the active member 301 has not yet moved to the needle retraction position along the first direction, the working part 502 (one end of the needle insertion spring 601) directly abuts against the active mounting part 303 and is connected to the active mounting part 303, thereby achieving a separable connection between the working part 502 and the active member 301. Alternatively, the working part 502 can be located on the active slider 304, and the working part 502 can be indirectly connected to the active mounting part 303 through the active slider 304. When the active member 301 has not moved to the needle retraction position along the first direction, the working part 502 is connected to the active mounting part 303 through the active slider 304, and the active mounting part 303 supports the working part 502 at the needle tip. The active component 301 moves in the first direction, and the active mounting part 303 moves relative to the active slider 304 in the first direction. The active mounting part 303 also moves relative to the working part 502 in the first direction, thereby realizing the movement of the working part 502 relative to the active component 301 in the first direction. During this period, the active component 301 does not move relative to the working part 502 in the needle tip axial direction, so the working part 502 and the active component 301 are relatively fixed in the needle tip axial direction until the active component 301 moves to the needle retraction position. The active slider 304 leaves the active mounting part 303 through the end of the active mounting part 303, and the active mounting part 303 disconnects from the active slider 304. Thus, the working part 502, which is directly connected to the active slider 304, disconnects from the active mounting part 303, and the active mounting part 303 no longer has the function of limiting and supporting the working part in the needle tip axial direction.

[0077] The retraction action of the needle tip 202 in this application is not limited to relying on gravity as described above, but can also be achieved by elastic coupling or magnetic coupling between the needle 201 and the main body 101, as detailed below.

[0078] See Figure 6 , Figure 7 The needle insertion spring 601, located between working section two 502 and working section one 501, can apply a thrust to the needle 201 near the medication chamber 102 via working section one 501. The rapid-puncture inhaler also includes a needle withdrawal unit. Figure 6 , 7 The needle retraction unit shown includes a needle retraction elastic element, which can be a tension elastic element. Figure 6 , 7 The needle retraction elastic element shown is a needle retraction spring 607. Of course, the needle retraction elastic element can also be a tension-type elastic element such as a rubber block that can undergo elastic deformation after being stretched. The following is an example illustrating the case where the needle retraction elastic element is a needle retraction spring 607.

[0079] See Figure 6 , Figure 7 The needle insertion spring 601 is located between the active mounting portion 303 of the active member 301 and the drug reservoir 102. One end of the needle retraction spring 607 is fixedly connected to the needle rod 204, and the other end is fixedly connected to the main body 101. The needle retraction spring 607 can apply a pulling force to the needle 201 along the needle tip axial direction away from the drug reservoir 102. When the active member 301 is in the released position, the needle retraction spring 607 can be in a natural state, without elastic deformation, or in a stretched state with elastic deformation. However, the pushing force of the needle insertion spring 601 on the needle 201 needs to be greater than the pulling force of the needle retraction spring 607 on the needle 201, so that the needle 201 tends to move closer to the drug reservoir under the action of the needle insertion spring 601. See also... Figure 6 When the active member 301 is in the initial position, the needle insertion spring 601 is compressed, and the active mounting part 303 of the active member 301 provides support to the working part 502. The active member 301 supports the assembly consisting of the needle insertion spring 601 and the needle 201. The compressed needle insertion spring 601 applies a force along the needle tip axial direction towards the drug reservoir 102 to the needle 201 through the working part 501. The thrust of the needle insertion spring 601 on the needle 201 is greater than that of the needle retraction spring 607. The tension on the needle 201 causes the needle tip 202 to tend to perform a piercing action, preventing the needle 201 from being pulled by the retraction spring 607. When the driving member 301 moves to the release position, the needle 201 performs a piercing action under the elastic action of the insertion spring 601. At the same time, the insertion spring 601 stretches the retraction spring 607 through the needle 201, causing further elastic deformation of the retraction spring 607. This increases the tension (retraction force) exerted by the retraction spring 607 on the needle 201. See also... Figure 7 When the active member 301 moves to the needle retraction position along the first direction, the working part 2 502 separates from the active member 301. The active mounting part 303 of the active member 301 stops applying support force to the working part 2 502. The active mounting part 303 no longer supports the needle 201 through the needle insertion spring 601. The active member 301 stops supporting the needle insertion spring 601 and the needle 201. The needle 201, which has lost the support of the active mounting part 303, is pulled away from the drug chamber by the needle retraction spring 607, which undergoes elastic deformation. The needle 201 moves away from the drug chamber 102 along the needle tip axis. The needle 201 performs the needle retraction action.

[0080] The stretchable elastic element can be connected to the needle 201 and the main body 101 at any position. Those skilled in the art to which this application pertains are able to make adaptive adjustments to the connection position so that the needle 201 can perform a piercing action. The stretchable elastic element can be stretched and undergo elastic deformation to generate an elastic force as a needle retraction force, which can pull the needle 201 away from the drug chamber.

[0081] The implementation of the needle retraction elastic element in this application is not limited to the implementation of the needle retraction spring 607 described above. Another implementation of the needle retraction elastic element is also provided. The needle retraction unit may also include a compression elastic element 610. See [link to relevant documentation]. Figure 8 The compression elastic element 610 includes a needle retraction spring 606. One end of the needle retraction spring 606 abuts against the main body 101, and the other end abuts against the side of the first limiting part 203 near the drug reservoir 102, or is fixedly connected to the needle 201. When the active element 301 is in the initial position, the needle retraction spring 606 is not compressed or has a small degree of elastic deformation, so the thrust (needle retraction force) exerted by the needle retraction spring 606 on the needle 201 along the needle tip axial direction away from the drug reservoir 102 is small. Therefore, the force (needle insertion force) exerted by the elastically deformed needle insertion spring 601 on the needle 201 along the needle tip axial direction towards the drug reservoir 102 is small. The force exerted on the needle 201 by the needle retraction spring 606 is greater than the retraction force. When the driving member 301 moves to the release position, the needle insertion force drives the needle 201 to overcome the retraction force and move along the needle tip axis towards the medicine chamber 102. The needle 201 performs a piercing action and moves towards the medicine chamber 102, which increases the compression of the needle retraction spring 606, thereby increasing the retraction force. When the driving member 301 moves to the retraction position, the working part 2 502, the needle 201 and the driving member 301 are separated. After the driving member 301 no longer supports the needle 201 through the needle insertion spring 601, the needle 201 performs a retraction action under the action of the retraction force.

[0082] Those skilled in the art to which this application pertains will understand that a compressible elastic element 610, such as a rubber block, can be used instead of the needle retraction spring 606. When the needle 201 performs the piercing action, the length of the compressible elastic element 610 is compressed, causing elastic deformation and generating an elastic force as the needle retraction force.

[0083] The compression elastic element 610 can be connected to the needle 201 and the main body 101 at any position. Those skilled in the art to which this application pertains are able to make adaptive adjustments to the connection position so that the needle 201 can perform a piercing action. The compression elastic element 610 can be stretched and undergo elastic deformation to generate an elastic force as a needle retraction force, which can pull the needle 201 away from the drug chamber.

[0084] The retractable needle elastic element in this application can also be other structures, see Figure 9 As shown in Figure (a), the compression elastic element 610 (needle retraction elastic element) is a thin-walled, elastic structure. The compression elastic element 610 is fixedly connected to the main body 101. The first limiting part 203 has a contact surface 611 on the side near the medicine tank 102. When the active member 301 is in the initial position, the compression elastic element 610 and the contact surface 611 are spaced apart axially upwards at the needle tip 202. When the needle 201 performs the piercing action, the contact surface 611 approaches the compression elastic element 610 and moves with the needle. When the puncture action is performed, the compression elastic element 610 begins to abut against the abutment surface 611. The compression elastic element 610 undergoes elastic deformation, and through the abutment surface 611, it generates a pushing force (needle retraction force) on the needle 201 away from the drug chamber 102. When the driving element 301 moves to the needle retraction position, the working part 2 502, the needle 201, and the driving element 301 separate. After the driving element 301 no longer supports the needle 201 through the needle insertion spring 601, the needle 201 performs the needle retraction action under the action of the needle retraction force. Of course, the compression elastic element 610 can also be fixedly mounted on the needle 201, and the abutment surface 611 can be fixedly mounted on the main body 101. The needle retraction elastic element can also be implemented in other ways. For example, the compression elastic element 610 is a rubber ring. The rubber ring is sleeved on the needle 201. The rubber ring is not fixed to the needle 201. The rubber ring is located on the side of the first limiting part 203 near the medicine chamber 102. The main body 101 is provided with abutment surface 611. When the needle 201 performs the piercing action, the rubber ring located between the first limiting part 203 and the main body 101 is squeezed and undergoes elastic deformation. The rubber ring applies a needle retraction force to the needle tip 202 through the first limiting part 203.

[0085] See Figure 9As shown in Figure (b), the needle retraction elastic element includes two independent compression elastic elements 610. The compression elastic element 610 can be a rubber ring, a rubber block, or an elastic thin-walled structure. When compressed, the compression elastic element 610 can undergo elastic deformation. One of the two compression elastic elements 610 is fixedly connected to the needle 201, and the other is fixedly connected to the main body 101. When the active element 301 is in the initial position, the two compression elastic elements 610 are spaced apart axially at the needle tip 202. When the needle 201 performs the piercing action, the distance between the two compression elastic elements 610 axially at the needle tip decreases. As the piercing action proceeds, the two compression elastic elements 610 begin to abut against each other and compress each other, resulting in elastic deformation. The main body 101 applies a force along the needle tip axially away from the drug chamber 102 to the needle tip 202 through the two elastically deformed compression elastic elements 610. The needle retraction unit has a needle retraction force on the needle tip 202.

[0086] Those skilled in the art to which this application pertains will understand that, of course, the specific structure of the needle retraction elastic element, as well as the connection method and connection position between the needle retraction elastic element and the needle 201 or the main body 101, may have other forms. When the needle 201 performs a piercing action, the needle retraction elastic element can undergo elastic deformation. The needle retraction elastic element can apply a needle retraction force to the needle. When the active member 301 is in the initial position and the release position, the needle retraction force of the needle retraction elastic element on the needle 201 should be less than the needle insertion force of the needle insertion unit on the needle 201. After the needle 201 overcomes the needle retraction force with the needle insertion force, it can approach the drug chamber 102 along the axial direction of the needle tip 202, so that the needle 201 performs a piercing action until the working part 2 502 and the needle 201 are separated from the active member 301. The active member 301 no longer applies a force to the needle 201 along the axial direction of the needle tip to approach the drug chamber. The needle 201 performs a needle retraction action under the action of the elastic force generated by the needle retraction elastic element that has undergone elastic deformation.

[0087] In this application, the method of generating the needle retraction force by the needle retraction unit is not limited to the method of using the elastic force generated by the needle retraction elastic element as described above. It can also be the method of using magnetic force as the needle retraction force, which will be described in detail below.

[0088] Those skilled in the art to which this application pertains will understand that the repulsive force between like poles of magnets described below creates a magnetic repulsion between two magnets. This can be achieved by arranging the like poles of the two magnets opposite each other, such as arranging the N poles of the two magnets opposite each other, or arranging the S poles of the two magnets opposite each other. Thus, there is a magnetic repulsion between the two magnets. The magnitude of the magnetic repulsion depends on the strength of the magnetic field generated by the magnets. The stronger the magnetic field, the stronger the magnetic repulsion, and the weaker the magnetic field, the weaker the magnetic repulsion. It also depends on the distance between the two magnets. The smaller the distance, the stronger the magnetic repulsion, and the larger the distance, the weaker the magnetic repulsion. Those skilled in the art can adjust the magnitude of the magnetic repulsion between the two magnets by adjusting these two parameters.

[0089] The magnetic attractor described below can be a magnet or a solid structure containing iron, cobalt, or nickel that attracts a magnet. There is a magnetic attraction between the magnet and the magnetic attractor. When the magnetic attractor is a magnet, the magnet and the magnetic attractor can achieve this magnetic attraction by aligning their opposite magnetic poles. For example, the N pole of the magnetic attractor can be aligned with the S pole of the magnet, or vice versa. The opposite magnetic poles of the magnetic attractor and the magnet are aligned positively within the effective working distance, thus creating a magnetic attraction between them. The magnitude of the magnetic attraction depends on the strength of the magnet's magnetic field; a stronger magnetic field results in a stronger attraction, and a weaker magnetic field results in a weaker attraction. It also depends on the distance between the magnet and the magnetic attractor; a smaller distance results in a stronger attraction, and a larger distance results in a weaker attraction. Technicians can adjust the magnitude of the magnetic attraction between the magnet and the magnetic attractor by adjusting these two parameters.

[0090] See Figure 10In Figure (a), the needle retraction unit includes two needle retraction magnets 608. One needle retraction magnet 608 is fixedly connected to the main body 101, and the other needle retraction magnet 608 is fixedly connected to the needle 201. The needle retraction magnet 608 connected to the main body 101 is located between the needle retraction magnet 608 connected to the first limiting part 203 and the medicine container 102. The two needle retraction magnets 608 have a repulsive force between like poles. The needle retraction magnet 608 connected to the main body 101 has a magnetic repulsive force on the needle retraction magnet 608 fixedly connected to the needle 201 along the axial direction of the needle tip 202, thereby forming a needle retraction force on the needle 201. When the active member 301 is in the released position, the insertion force on the needle 201 is greater than the retraction force applied to the needle 201 due to the magnetic coupling between the two retraction magnets 608. As a result, the working part 1 501 can drive the needle 201 to perform the piercing action. As the needle 201 performs the piercing action, the distance between the two retraction magnets 608 decreases, the magnetic repulsion increases, and the retraction force continuously increases. When the active member 301 moves to the retraction position and the working part 2 502 separates from the active mounting part 303, the active mounting part 303 no longer supports the needle 201 through the insertion spring 601. As a result, the needle 201 performs the retraction action due to the magnetic repulsion (retraction force) between the two retraction magnets 608.

[0091] Those skilled in the art to which this application pertains will understand that when the needle 201 performs the needle retraction action through the magnetic repulsion between the two needle retraction magnets 608, the two needle retraction magnets 608 do not need to be fixedly connected to the body 101 and the needle 201. See [reference needed]. Figure 10 In Figure (a), two needle-retracting magnets 608 are located between the first limiting part 203 and the medicine chamber 102, and are both sleeved on the needle 201. When the active member 301 is in the initial position, under the action of the magnetic repulsion between the two needle-retracting magnets 608, the two needle-retracting magnets 608 respectively abut against the first limiting part 203 and the main body 101, and are limited in movement by the physical structure of the first limiting part 203 and the main body 101, so that the two needle-retracting magnets 608 are kept in a fixed position to a certain extent.

[0092] The needle retraction unit applies retraction force to the needle 201 not only through magnetic coupling between two retraction magnets 608 with like poles repelling each other, but also through magnetic coupling with opposite poles attracting each other. See [link to relevant documentation]. Figure 10In Figure (b), the needle retraction unit includes a needle retraction magnet 608 and a needle retraction magnetic chuck 609 that can magnetically attract the needle retraction magnet 608. There is a magnetic attraction between the needle retraction magnet 608 and the needle retraction magnetic chuck 609. The needle retraction magnet 608 is fixedly connected to the needle 201, and the needle retraction magnetic chuck 609 is fixedly connected to the main body 101. The needle retraction magnetic chuck 609 is located on the side of the needle retraction magnet 608 away from the drug chamber 102 in the axial direction of the needle tip. The needle retraction magnetic chuck 609 has a magnetic attraction force on the needle retraction magnet 608 in the axial direction of the needle tip away from the drug chamber 102. The needle retraction magnetic chuck 609 applies a needle retraction force to the needle 201 through the magnetic attraction between it and the needle retraction magnet 608. When the active member 301 is in the release position, the pushing force (insertion force) applied to the needle 201 by the needle insertion spring 601 through the working part 501 is greater than the needle retraction force applied to the needle 201 by the needle retraction magnetic member 609. As a result, the needle 201 performs a piercing action under the action of the needle insertion spring 601. When the active member 301 moves to the needle retraction position and the working part 502 separates from the active mounting part 303, the active mounting part 303 no longer supports the needle 201 through the needle insertion spring 601. The needle retraction magnetic member 609 attracts the needle retraction magnet 608 to approach through magnetic attraction, and the needle 201 performs a needle retraction action under the action of the needle retraction force.

[0093] Of course, the needle retraction magnet 608 can also be fixedly connected to the main body 101, and the needle retraction magnetic suction component 609 can be fixedly connected to the needle 201. The needle retraction magnetic suction component 609 is located on the side of the needle retraction magnet 608 away from the medicine chamber 102 in the axial direction of the needle tip. The needle retraction magnet 608 applies a needle retraction force to the needle 201 through the needle retraction magnetic suction component 609. This will not be elaborated further here.

[0094] Those skilled in the art to which this application pertains will understand that the method by which the driving working part 501 moves relative to the working part 502 to enable the piercing needle 201 to perform the piercing action is not limited to the method of the needle insertion spring 601 described above. It can also be implemented using a needle insertion tension spring 602 that undergoes elastic deformation after being stretched. See [link to relevant documentation]. Figure 11 In the axial direction of the needle tip, working part one 501 is located on the side of working part two 502 away from the drug reservoir 102. Working part two 502 is located between working part one 501 and drug reservoir 102, and working part two 502 is connected to active mounting part 303 via active slider 304. When the active member 301 moves to the needle retraction position, the active slider 304 can disengage from the end of active mounting part 303. See also Figure 11When the active component 301 is in the initial position, the needle insertion spring 602 is stretched and undergoes elastic deformation. Since the active mounting part 303 provides support to the active slider 304 along the needle tip axial direction towards the drug reservoir 102, and the working part 2 502 is fixedly connected to the active slider 304, the position of the working part 2 502 relative to the drug reservoir does not change when the active component 301 is in the initial position. The working part 2 502 applies a force along the needle tip axial direction towards the drug reservoir 102 to the working part 1 501 through the elastically deformed needle insertion spring 602. A working part 501 is fixedly connected to the needle 201, thereby elastically deforming the insertion spring 602, which applies a pulling force (insertion force) to the needle 201 along the needle tip axial direction towards the drug reservoir 102, causing the needle 201 to tend to perform a piercing action. When the driving member 301 moves to the release position, the driving member 301 no longer prevents the needle 201 from approaching the drug reservoir 102 through the limiting part and the first limiting part 203. The needle 201 moves relative to the driving slider 304 and the working part 502 along the needle tip axial direction towards the drug reservoir 102, and the needle 201 performs the piercing action. Those skilled in the art will understand that when the driving member 301 is in the release position, the insertion force should be greater than the retraction force in the form of gravity, elasticity, and magnetic force that enables the needle 201 to retract, as described above, to ensure that the needle 201 can smoothly perform the piercing action.

[0095] Those skilled in the art to which this application pertains will understand that elastic elements such as metal springs or rubber bands can also be used to replace the needle insertion spring 602. An elastic element that undergoes stretching and elastic deformation is used. One end of the elastic element is provided in the working part 1 501, and the other end of the elastic element is provided in the working part 2 502. The working part 2 502 is located between the working part 1 501 and the medicine tank 102 in the axial direction of the needle tip 202, so as to provide the needle insertion force to the needle 201. This will not be described in detail here.

[0096] The needle insertion unit in this application is not limited to using the elastic coupling between working part 1 501 and working part 2 502 to provide the needle insertion force for the needle 201, but can also use the magnetic coupling between working part 1 501 and working part 2 502 to provide the needle insertion force for the needle 201, as detailed below.

[0097] See Figure 12In Figure (a), the working part 1 501 is fixedly connected to the needle 201, the working part 2 502 is movably disposed relative to the needle 201 in the axial direction of the needle tip, and is fixedly disposed relative to each other in the straight line direction of the first direction, the working part 2 502 is movably disposed relative to the active mounting part 303 in the straight line direction of the first direction, and is fixedly disposed relative to each other in the axial direction of the needle tip, the working part 2 502 is detachably connected to the active mounting part 303 of the active member 301, so that when the working part 2 502 is simultaneously connected to the needle rod 204 and the active mounting part 303 of the active member 301, the position of the working part 2 502 relative to the drug tank 102 is fixed.

[0098] When the active component 301 is in the initial position, the first working part 501 is located between the second working part 502 and the medicine tank 102. The first working part 501 and the second working part 502 are each provided with a needle insertion magnet 604. The same magnetic poles of the two needle insertion magnets 604 are arranged opposite each other in the axial direction of the needle tip, so that the first working part 501 and the second working part 502 have a like-pole repulsion effect. The second working part 502 has a magnetic repulsive force on the first working part 501 in the direction of the needle tip 202 axial direction close to the medicine tank 102. When the active member 301 is in the initial position, the blocking part 302 prevents the needle 201 from performing a piercing action through the first limiting part 203. The working part 1 501 tends to move towards the medicine tank 102 along the axial direction of the needle tip 202. When the active member 301 moves from the initial position to the release position along the first direction, the blocking part 302 disconnects from the first limiting part 203. The working part 2 502 drives the working part 1 501 to move towards the medicine tank 102 along the axial direction of the needle tip through magnetic repulsion. The working part 1 501 is connected to the needle 201. Thus, the working part 2 502 drives the needle 201 to move towards the medicine tank 102 relative to the working part 2 501 along the axial direction of the needle tip through magnetic repulsion with the working part 1 501. The needle 201 then performs a piercing action.

[0099] The magnetic coupling between working part 1 501 and working part 2 502 can also be achieved in other ways. The needle insertion unit includes a needle insertion magnet 604 and a needle insertion magnetic attractor 605 that can magnetically attract the needle insertion magnet 604. See [link to documentation]. Figure 12In Figure (b), working part two 502 is located between working part one 501 and the medicine tank 102 along the axial direction of the needle tip. Needle insertion magnet 604 is located in working part one 501, and needle insertion magnetic suction component 605 is located in working part two 502. Working part two 502 is fixedly connected to the active slider 304. Working part two 502 has a magnetic attraction force on working part one 501 along the axial direction of the needle tip 202 towards the medicine tank 102, causing working part one 501 to have a magnetic attraction force along the axial direction of the needle tip 202 towards the medicine tank 102. The needle tip 202 tends to move axially toward the medicine container 102. Alternatively, the needle insertion magnet 604 can be located in the second working part 502, and the needle insertion magnetic attractor 605 can be located in the first working part 501. The second working part 502 has a magnetic attraction force on the first working part 501 along the axial direction of the needle tip. When the active member 301 is in the release position, the magnetic attraction force of the second working part 502 on the first working part 501 can be used as the needle insertion force to drive the needle 201 to perform the piercing action.

[0100] Those skilled in the art to which this application pertains will understand that the second working part 502 is coupled to the first working part 501 via elastic coupling or magnetic coupling. Through the elastic or magnetic force between the first working part 501 and the second working part 502, the first working part 501 applies an insertion force to the needle 201 to perform the piercing action. When the active member 301 is in the release position, the insertion force should be greater than the retraction force in the form of gravity, elasticity, or magnetic force that enables the needle 201 to retract, as described above, to ensure that the needle 201 can smoothly perform the piercing action until the active member 301 moves to the retraction position along the first direction. The second working part 502 is then separated from the active mounting part 303 directly or indirectly through the active slider 304. After the active mounting part 303 no longer supports the needle 201 through the interaction between the second working part 502 and the first working part 501, the needle 201 performs the retraction action under the action of the retraction force, causing the needle tip 202 to exit the drug carrier. A hole can be formed on the drug carrier for the drug to leave the drug carrier.

[0101] When the needle insertion unit acts as a component for applying needle insertion force to the needle 201 via magnetically coupled working part 1 501 and working part 2 502, it also has other embodiments for applying needle retraction force to the needle 201, which are described in detail below.

[0102] First, the piercing action of the needle 201 is achieved by the magnetic repulsion between the working part 1 501 and the working part 2 502. That is, the working part 1 501 is located between the working part 2 502 and the medicine tank 102. The working part 2 502 has a magnetic repulsion force on the working part 1 501 in the direction of approaching the medicine tank 102 along the axial direction of the needle tip 202, so that the working part 1 501 tends to approach the medicine tank 102 in the direction of approaching the medicine tank 102 along the axial direction of the needle tip 202. The needle insertion method is described when the magnetic repulsion force of the working part 2 502 on the working part 1 501 is used as the needle insertion force to drive the needle 201 to perform the piercing action. The method of driving the needle 201 to perform the piercing action and the needle withdrawal action is explained.

[0103] In one embodiment of this application, see Figure 13 In Figure (a), the working part 502 and the needle 201 are axially movable relative to each other in the needle tip direction and are fixed relative to each other in the straight line direction of the first direction. The working part 502 and the active mounting part 303 are axially movable relative to each other in the straight line direction of the first direction and are fixed relative to each other in the needle tip direction. The working part 502 and the active mounting part 303 of the active member 301 are detachably connected so that when the working part 502 is simultaneously connected to the needle rod 204 and the active mounting part 303 of the active member 301, the position of the working part 502 relative to the drug tank 102 is fixed.

[0104] The rapid puncture inhaler also includes a working part 3 503 fixedly installed on the main body 101. Both working part 1 501 and working part 2 502 are provided with needle insertion magnets 604, and working part 3 503 is provided with needle retraction magnets 608. Working part 3 503, working part 1 501 and working part 2 502 are arranged in sequence along the direction away from the drug chamber 102 along the axial direction of the needle tip 202. Working part 3 503 is provided with space to avoid the needle 201, so that the needle 201 can move normally along the axial direction of the needle tip. Working part 1 501 has a repulsive force with working parts 2 502 and 3 503. The magnetic repulsion force of working part 2 502 on working part 1 501 is in the direction of the needle tip axial direction towards the drug chamber 102. Working part 2 502 applies an insertion force to the needle 201 through working part 1 501. The repulsion force of working part 3 503 on working part 1 501 is in the direction of the needle tip axial direction away from the drug chamber 102. Working part 3 503 applies a retraction force to the needle 201 through working part 1 501. When the driving member 301 moves to the release position in the first direction, the magnetic repulsion force of working part 2 502 on working part 1 501 is greater than the magnetic repulsion force of working part 3 503 on working part 1 501. Therefore, the insertion force is greater than the retraction force. Working part 2 502 drives the needle 201 through working part 1 501 to overcome the retraction force and perform the puncture action. During this process, the position of working part 1 501 relative to working part 2 502 and working part 3 503 in the axial direction changes. The distance between working part 2 502 and working part 1 501 in the axial direction at the needle tip increases, and the magnetic repulsion force of working part 2 502 on working part 1 501 decreases. The distance between working part 3 503 and working part 1 501 in the axial direction at the needle tip decreases, and the magnetic repulsion force of working part 3 503 on working part 1 501 increases. When the driving member 301 moves from the release position to the needle retraction position along the first direction, working part 2 501 is connected to the working part 502 501 502 503 ... The active slider 304 of 02 separates from the active member 301. The active member 301 no longer provides the working part 2 502 with a force that moves towards the drug chamber 102 along the axial direction of the needle tip 202. The active member 301 stops providing support to the needle 201 through the working part 2 502 and the working part 1 501. Under the action of the working part 3 503 applying a needle retraction force to the needle 201 through the repulsive force of the working part 1 501, the needle 201 moves away from the drug chamber 102 along the axial direction of the needle tip, thereby the needle 201 performs the needle retraction action.

[0105] In another embodiment of this application, see [link to application]. Figure 13In Figure (b), working part 1 501 is fixedly mounted on the needle 201, working part 2 502 is fixedly mounted on the active component 301, and working part 3 503 is fixedly mounted on the main body 101. Working part 3 503, working part 1 501, and working part 2 502 are arranged sequentially along the axial direction away from the drug chamber 102 of the needle tip 202. Working part 1 501 has a repulsive force with the like poles of working part 2 502 and working part 3 503. The magnetic repulsive force of working part 2 502 on working part 1 501 is in the direction along the axial direction of the needle tip towards the drug chamber 102. Working part 2 502 applies a needle insertion force to the needle 201 through working part 1 501. The magnetic repulsive force of working part 3 503 on working part 1 501 is in the direction along the axial direction of the needle tip away from the drug chamber 102. Working part 3 503 applies a needle retraction force to the needle 201 through working part 1 501. When the driving member 301 moves along the first direction to the release position, the insertion force is greater than the retraction force. The second working part 502, through the first working part 501, drives the needle 201 to perform a piercing action. The magnetic repulsion force of the second working part 502 on the first working part 501 decreases, while the magnetic repulsion force of the third working part 503 on the first working part 501 increases. When the driving member 301 moves along the first direction from the release position to the retraction position, the second working part 502 leaves the effective range of action of the first working part 501. Figure 13 As illustrated in Figure (b), the working part 2 502 is located below the working part 1 501 and is spaced apart from the working part 1 501 in the straight line direction of the first direction. This makes the magnetic repulsion force of the working part 2 502 on the working part 1 501 less than the magnetic repulsion force of the working part 3 503 on the working part 1 501. The insertion force of the working part 2 502 on the needle 201 is less than the retraction force of the working part 3 503 on the needle 201. The working part 3 503, which is fixedly connected to the main body 101, pushes the needle 201 to move away from the drug chamber 102 along the needle tip axis through the magnetic repulsion force of the working part 1 501. The needle 201 performs the retraction action.

[0106] In another embodiment of this application, see [link to application]. Figure 14The first working part 501 is fixedly connected to the needle 201, and the second working part 502 is fixedly connected to the active mounting part 303. The rapid puncture inhaler also includes a needle retraction magnetic member 609 fixedly mounted to the main body 101 and capable of magnetic attraction with the first working part 501. The second working part 502 is located between the first working part 501 and the needle retraction magnetic member 609 along the axial direction of the needle tip. The second working part 502 has a repulsive force on the first working part 501, and applies an insertion force to the needle 201 through the first working part 501, which is fixedly connected to the needle 201. The needle retraction magnetic member 609 has a magnetic attraction force on the first working part 501 along the axial direction of the needle tip 202 away from the drug reservoir 102, and applies a needle retraction force to the needle 201 through the first working part 501. When the active component 301 moves to the release position along the first direction, the magnetic repulsion force of the second working part 502 on the first working part 501 is greater than the magnetic attraction force of the needle retraction magnetic component 609 on the first working part 501, and the needle insertion force is greater than the needle retraction force. The second working part 502 drives the needle 201 through the first working part 501 to perform the piercing action. When the active component 301 moves from the release position to the needle retraction position along the first direction, as the active component 301 moves along the first direction, the second working part 502, which is fixedly connected to the active component 301, leaves the effective range of action of the first working part 501. Figure 14 To illustrate the direction, the second working part 502 is located below the first working part 501 and is spaced apart from the first working part 501 in the straight line direction of the first direction. The magnetic attraction force of the second working part 502 on the first working part 501 is less than the magnetic attraction force of the third working part 503 on the first working part 501. The needle retraction magnetic member 609, which is fixedly connected to the main body 101, attracts the first working part 501 to move closer. The first working part 501 drives the needle 201 to perform the needle retraction action.

[0107] In another embodiment of this application, see [link to application]. Figure 15In Figure (a), the second working part 502 is sleeved on the needle rod 204. The second working part 502 is fixedly connected to the active slider 304. The second working part 502 is connected to the active mounting part 303 of the active member 301 through the active slider 304. Alternatively, the second working part 502 can be sleeved on the needle rod 204. The second working part 502 is located on the side of the active mounting part 303 along the needle tip axis close to the drug chamber 102. Through the like-particle repulsion between the second working part 502 and the first working part 501, when the active member 301 is in the initial position, the second working part 502 abuts against the active mounting part 303. A similar description has been given above. Alternatively, both the active slider 304 and the second working part 502 can be sleeved on the needle rod 204, which will not be repeated here. The working part 502 and the needle 201 are movably arranged relative to each other in the axial direction of the needle tip and are fixedly arranged relative to each other in the straight line direction of the first direction. The working part 502 and the active mounting part 303 are movably arranged relative to each other in the straight line direction of the first direction and are fixedly arranged relative to each other in the axial direction of the needle tip. The working part 502 and the active mounting part 303 of the active member 301 are detachably connected so that when the working part 502 is simultaneously connected to the needle rod 204 and the active mounting part 303 of the active member 301, the position of the working part 502 relative to the drug tank 102 is fixed.

[0108] The rapid-piercing inhaler also includes a needle-retracting magnetic suction component 609 fixedly mounted on the main body 101. Along the axial direction of the needle tip 202 away from the drug chamber 102, the working part 1 501, the working part 2 502, and the needle-retracting magnetic suction component 609 are arranged sequentially. The working part 1 501 and the working part 2 502 have a repulsive force between like poles, and the needle-retracting magnetic suction component 609 has a magnetic attraction effect on the working part 2 502. Although the needle-retracting magnetic suction component 609 has a magnetic attraction force on the working part 2 502 along the axial direction of the needle tip away from the drug chamber 102, when the active slider 304 is connected to the active mounting part 303, the active component 301 provides support and limitation for the working part 2 502 through the active slider 304. Therefore, when the active slider 304 is connected to the active mounting part 303, the working part 2 502 will not move along the axial direction of the needle tip.

[0109] See Figure 15 In Figure (a), the portion of the puncture needle 201 located between the second working part 502 and the needle retraction magnetic member 609 also has a driving part 504, the diameter of which is larger than the diameter of the second working part 502. When the driving member 301 is in the initial position, the driving part 504 and the second working part 502 are spaced apart; when the driving member 301 moves along the first direction to the release position, the second working part 502 applies a magnetic repulsive force to the first working part 501, and the second working part 502 applies a needle insertion force to the puncture needle 201 through the first working part 501, and the second working part 502 drives the puncture needle 201 to perform the puncture action; when the driving member 301 moves along the first direction from the release position to the needle retraction position, the driving slider 304 separates from the working guide rail, see [reference]. Figure 15 In Figure (b), the working part 2 502, which is fixedly connected to the active slider 304, is separated from the active member 301. The active member 301 no longer provides the working part 2 502 with a force that moves towards the drug chamber 102 along the axial direction of the needle tip 202. The needle retraction magnetic member 609 pulls the working part 2 502 closer along the axial direction of the needle tip through magnetic attraction. When the working part 2 502 moves closer to the needle retraction magnetic member 609, it will abut against the driving part 504. At this time, the needle retraction magnetic member 609 can apply a needle retraction force to the needle 201 through the working part 2 502 and the driving part 504, so that the needle 201 performs a needle retraction action.

[0110] When the piercing action of the needle 201 is achieved by using the magnetic attraction between the working part 1 501 and the working part 2 502, that is, in the axial direction of the needle tip 202, the working part 2 502 is located between the working part 1 501 and the medicine tank 102; one of the working part 1 501 and the working part 2 502 is provided with a needle insertion magnet 604, and the other is provided with a needle insertion magnetic attracting member 605. The working part 2 502 has a magnetic attraction force on the working part 1 501 along the axial direction of the needle tip 202 towards the medicine tank 102, so that the working part 1 501 tends to move towards the medicine tank 102 along the axial direction of the needle tip 202. The needle insertion method is described when the magnetic attraction force of the working part 2 502 on the working part 1 501 is used as the needle insertion force to drive the needle 201 to perform the piercing action. The method of driving the needle 201 to perform the piercing action and the needle withdrawal action is explained.

[0111] See Figure 16 The rapid-puncture inhaler also includes a needle retraction magnetic attachment 609, a working part 501 fixedly connected to the needle 201, a working part 502 fixedly connected to the active component 301, and a needle retraction magnetic attachment 609 fixedly connected to the main body 101. The working part 502, working part 501, and needle retraction magnetic attachment 609 are arranged sequentially along the axial direction of the needle tip 202 away from the drug reservoir 102. The working part 502 has a magnetic attraction to the working part 501, and the working part 501 is fixedly connected to the needle 201. Therefore, the working part 502 can apply an insertion force along the axial direction of the needle tip towards the drug reservoir 102 to the needle 201 through the working part 501. There is a magnetic attraction between the working part 501 and the needle withdrawal magnetic 609. The needle withdrawal magnetic 609 can apply a magnetic attraction force to the working part 501, thereby the needle withdrawal magnetic 609 applies a needle withdrawal force to the needle 201 along the needle tip axis away from the drug chamber 102 through the working part 501.

[0112] When the driving element 301 moves to the release position along the first direction, the magnetic attraction force of the second working part 502 on the first working part 501 is greater than the magnetic attraction force of the needle retraction magnetic element 609 on the first working part 501. The second working part 502 drives the needle 201 to perform the piercing action through the first working part 501. When the driving element 301 moves from the release position to the needle retraction position along the first direction, since the second working part 502 is fixedly connected to the driving element 301, the second working part 502 moves along the first direction with the driving element 301. The second working part 502 gradually moves away from the range of mutual magnetic interaction with the first working part 501. Figure 16 To illustrate with an example, the working part 2 502 is positioned above the working part 1 501, and is spaced apart from the working part 1 501 in the straight line direction of the first direction. At this time, the magnetic attraction force of the working part 2 502 on the working part 1 501 is less than the magnetic attraction force of the needle withdrawal magnetic 609 on the working part 1 501, that is, the needle insertion force is less than the needle withdrawal force. The needle withdrawal magnetic 609 attracts the working part 1 501, which is fixedly connected to the needle 201, to move closer along the needle tip axial direction. The needle withdrawal magnetic 609 drives the needle 201 to perform the needle withdrawal action through the working part 1 501.

[0113] In another embodiment of this application, see [link to application]. Figure 17 In Figure (a), the working part 502 and the needle 201 are axially movable relative to each other in the needle tip direction and are fixed relative to each other in the straight line direction of the first direction. The working part 502 and the active mounting part 303 are axially movable relative to each other in the straight line direction of the first direction and are fixed relative to each other in the needle tip direction. The working part 502 and the active mounting part 303 of the active member 301 are detachably connected so that when the working part 502 is simultaneously connected to the needle rod 204 and the active mounting part 303 of the active member 301, the position of the working part 502 relative to the drug tank 102 is fixed.

[0114] The rapid-piercing inhaler also includes a needle retraction magnetic 609. Along the axial direction of the needle tip 202 away from the medication chamber 102, the working part 2 502, the working part 1 501, and the needle retraction magnetic 609 are arranged sequentially. There is a magnetic attraction between the working part 1 501 and the needle retraction magnetic 609. The working part 1 501 is fixedly connected to the needle 201, and the needle retraction magnetic 609 is fixedly connected to the main body 101. When the active member 301 moves from the initial position to the release position... At this time, the second working part 502 has a magnetic attraction force on the first working part 501 along the axial direction of the needle tip towards the medicine tank 102. The first working part 501 and the needle 201 are fixedly connected. The second working part 502 applies an insertion force to the needle 201 through the first working part 501. The retraction magnetic member 609 has a magnetic attraction force on the first working part 501 along the axial direction of the needle tip away from the medicine tank 102. The retraction magnetic member 609 applies a retraction force to the needle 201 through the first working part 501. When the driving member 301 moves from the initial position to the release position along the first direction, the magnetic attraction force of the second working part 502 on the first working part 501 is greater than the magnetic attraction force of the retraction magnetic member 609 on the first working part 501. The insertion force is greater than the retraction force. The second working part 502 drives the needle 201 to perform a puncture action through the first working part 501. When the active member 301 moves from the release position to the needle retraction position along the first direction, the working part 2 502 separates from the active member 301. The active member 301 no longer provides the working part 2 502 with a force that moves towards the drug chamber 102 along the axial direction of the needle tip 202. The active member 301 no longer applies a supporting effect to the needle 201 along the axial direction of the needle tip 102 through the working part 2 502 and the working part 1 501. The active mounting part 303 stops providing support to the working part 2 502 and the needle 201. The needle retraction magnetic member 609 can pull the working part 1 501 closer by magnetic attraction, so that the needle 201 performs the needle retraction action.

[0115] Those skilled in the art to which this application pertains will understand that when work part 501 is... Figure 17 When the magnet shown in Figure (a) is used, the working part 2 502 and the needle retraction magnetic attractor 609 can be magnets or solid structures containing iron, cobalt, or nickel materials. When the working part 1 501 is... Figure 17 When the magnetic accumulator containing iron, cobalt and nickel materials is shown in Figure (b), both the working part 502 and the needle retraction magnetic accumulator 609 are magnets. Preferably, there is a magnetic attraction between the working part 502 and the needle retraction magnetic accumulator 609. Thus, after the working part 502 is separated from the active mounting part 303, the magnetic attraction between the working part 502 and the needle retraction magnetic accumulator 609 can assist the working part 501 to be attracted by the needle retraction magnetic accumulator 609.

[0116] In another embodiment of this application, see [link to application]. Figure 18The device includes a first working part 501 equipped with a needle insertion magnet 604, and a second working part 502 equipped with a needle insertion magnetic attractor 605 capable of magnetic attraction with the first working part 501. The rapid puncture-type inhaler also includes a third working part 503 equipped with a magnet, which can repel the first working part 501. Working parts 503, 502, and 501 are arranged sequentially along the axial direction of the needle tip 202 away from the drug chamber 102. The third working part 503 is fixedly connected to the main body 101, the second working part 502 is fixedly connected to the driving member 301, and the first working part 501 is fixedly connected to the needle 201. The third working part 503 has space to avoid the needle 201, allowing the needle 201 to move normally along the axial direction of the needle tip.

[0117] Working part 2 502 has a magnetic attraction force on working part 1 501 along the axial direction of the needle tip towards the drug chamber 102. Working part 1 501 and needle 201 are fixedly connected. Working part 2 502 applies a needle insertion force to needle 201 through working part 1 501. Working part 3 503 has a magnetic repulsion force on working part 1 501 along the axial direction of the needle tip away from the drug chamber 102. Working part 3 503 applies a needle retraction force to needle 201 through working part 1 501. When the driving member 301 moves from the initial position to the release position along the first direction, the magnetic attraction force of the second working part 502 on the first working part 501 is greater than the magnetic repulsion force of the third working part 503 on the first working part 501, and the needle insertion force is greater than the needle withdrawal force. The second working part 502 drives the needle 201 to perform the piercing action through the first working part 501. When the driving member 301 moves from the release position to the needle withdrawal position along the first direction, the second working part 502 moves away from the first working part 501 along the first direction with the driving member 301. The second working part 502 leaves the effective range of action of the first working part 501. The magnetic attraction force of the second working part 502 on the first working part 501 is less than the magnetic repulsion force of the third working part 503 on the first working part 501. The third working part 503 drives the needle 201 to perform the needle withdrawal action through the first working part 501.

[0118] In another embodiment of this application, see [link to application]. Figure 19The device includes a first working part 501 equipped with a needle-advancing magnetic 605, a second working part 502 equipped with a needle-advancing magnet 604, and a third working part 503 equipped with a needle-retracting magnet 608. The third working part 503 and the second working part 502 are mutually repelled by each other. The third working part 503, the second working part 502, and the first working part 501 are arranged sequentially along the axial direction away from the drug reservoir 102 at the needle tip 202. The third working part 503 is fixedly connected to the main body 101. The first working part 501 is fixedly connected to the needle 201. The second working part 502 is movable relative to the needle 201 in the axial direction of the needle tip, and is fixed relative to it in the linear direction of the first direction. The second working part 502 is movable relative to the active mounting part 303 in the linear direction of the first direction, and is fixed relative to it in the axial direction of the needle tip. The detachable connection between the second working part 502 and the active mounting part 303 of the active component 301 ensures that the position of the second working part 502 relative to the drug reservoir 102 is fixed when the second working part 502 is simultaneously connected to both the needle rod 204 and the active mounting part 303 of the active component 301. The second working part 502 exerts a magnetic attraction force on the first working part 501 along the needle tip axial direction towards the drug reservoir 102. The first working part 501 and the needle 201 are fixedly connected, and the second working part 502 applies a needle insertion force to the needle 201 through the first working part 501. The third working part 503 applies a magnetic repulsive force to the second working part 502 along the needle tip axial direction away from the drug reservoir 102. However, the active mounting part 303 provides a limiting and supporting function for the second working part 502, ensuring that the distance between the second working part 502 and the drug reservoir 102 in the needle tip axial direction does not change when the second working part 502 is connected to the active mounting part 303.

[0119] When the driving member 301 moves from the initial position to the release position along the first direction, the second working part 502 attracts the first working part 501 closer by magnetic attraction, and the first working part 501 drives the needle 201 to perform a piercing action; when the driving member 301 moves from the release position to the retraction position along the first direction, the second working part 502 disengages from the active mounting part 303, and the second working part 502 separates from the driving member 301. The driving member 301 no longer provides the second working part 502 with a force along the axial direction of the needle tip 202 towards the drug chamber 102, and the active mounting part 303 of the driving member 301 no longer restricts the position of the second working part 502 in the axial direction of the needle tip. Thus, the third working part 503 pushes the second working part 502 along the axial direction of the needle tip 202 away from the drug chamber 102 by magnetic repulsion. The third part 503 pushes the first part 501 away from the drug chamber through the second part 502, so that the needle 201 performs a piercing action. Preferably, when the needle 201 performs the piercing action, the first part 501 moves a certain distance along the needle tip axis towards the drug chamber 102, and then can be magnetically attracted to the second part 502. The first part 501 and the second part 502 form a combination. When the second part 502 is separated from the active mounting part 303, when the third part 503 pushes the second part 502 to move through the magnetic repulsion, it can push the combination of the first part 501 and the second part 502 to move along the needle tip axis away from the drug chamber 102. The first part 501 is fixedly connected to the needle 201, so that the needle 201 performs a needle retraction action under the action of the third part 503. Alternatively, the needle rod 204 may have a limiting structure between the working part 1 501 and the working part 2 502. When the active member 301 is in the initial position, the limiting structure and the working part 2 502 are spaced apart in the axial direction of the needle tip, so that the needle 201 can have a stroke to perform the piercing action. After the piercing action is completed, the working part 2 502 separates from the active mounting part 303. When the working part 3 503 pushes the working part 2 502 away from the drug chamber 102 along the axial direction of the needle tip by magnetic repulsion, the working part 2 502 abuts against the limiting structure. The working part 2 502 drives the needle 201 to move away from the drug chamber 102 along the axial direction of the needle tip through the limiting structure, and the needle 201 performs the needle retraction action.

[0120] Those skilled in the art to which this application pertains will understand that when the needle 201 moves axially along the needle tip using elasticity or magnetism, the elastic or magnetic components such as the needle insertion spring 601, needle insertion tension spring 602, needle insertion magnet 604, needle insertion magnetic suction component 605, needle withdrawal spring 606, needle withdrawal tension spring 607, needle withdrawal magnet 608, and needle withdrawal magnetic suction component 609 should be provided with space to allow the needle 201 to move, so as to avoid affecting the movement of the needle 201 along the needle tip axially.

[0121] The above describes a technical solution where the working part 2 502 and the active mounting part 303 of the active member 301 are fixedly connected or relatively movable, and can be detachably connected. Through elastic or magnetic coupling between the working part 1 501 and the working part 2 502, the needle 201 performs a piercing action, and gravity, elasticity, or magnetism causes the needle 201 to perform a retraction action. To reduce the risk of biocontamination, in one embodiment of this application, the main body 101 is provided with a first space 104, where the working part 1 501, the working part 2 502, and the active member 301 are located; the working part 2 502 is located on the active member 301; when the active member 301 moves from the release position to the retraction position along the first direction, the active member 301 no longer constrains the axial position of the needle tip 202 through the working part 2 502 and the working part 1 501, and the needle 201 performing the retraction action can enter the first space 104 through the connecting hole 103 from the drug chamber 102.

[0122] See Figure 1 , Figure 2 , Figure 7 The main body 101 has a first space 104 communicating with the medicine chamber 102 through a connecting hole 103. Working part one 501, working part two 502, active member 301, and needle retraction spring 607 are disposed in the first space 104. When the active member 301 moves from the release position to the needle retraction position along the first direction, working part two 502 separates from the active mounting part 303, and the needle tip 202 performing the needle retraction action can be pulled into the first space 104 through the connecting hole 103 by the needle retraction spring 607. (See also...) Figure 1 , Figure 2 , Figure 8The main body 101 is provided with a first space 104 that communicates with the medicine tank 102 through a connecting hole 103. Working part one 501, working part two 502, active member 301, and needle retraction spring 606 are disposed in the first space 104. When the active member 301 moves from the release position to the needle retraction position along the first direction, the active member 301 no longer constrains the axial position of the needle tip 202 through working part two 502 and working part one 501, and the needle tip 202 performing the needle retraction action can be pushed into the first space 104 by the needle retraction spring 606. Furthermore, one end of the needle retraction spring 606 abuts against the main body 101 and / or the needle retraction spring 606... The other end of the needle 6 abuts against the first limiting part 203 or other position of the needle 201, so that after the needle tip 202 enters the first space 104 in the direction away from the drug chamber 102 along the needle tip axis, the needle retraction spring 606 can separate from the main body 101 and / or the needle 201, disconnecting the connection. As a result, the main body 101 cannot prevent the needle 201 from moving away from the drug chamber 102 along the needle tip axis by the needle retraction spring 606. The needle 201 disconnects from the main body 101, enters the first space 104, and is stored in the first space 104, realizing the self-destruction of the inhaler and further preventing the needle 201 from being reused. Similarly, by using the abutment surface 611 and the compression elastic element 610 or two compression elastic elements 610, or by using magnetic coupling to make the needle 201 perform a retraction action, the working part 2 502 moves along the first direction with the active element 301, or the working part 2 502 can detach from the active mounting part 303, there is no force structure between the main body 101 and the needle 201 that restricts the needle 201 from moving away from the drug tank 102 along the needle tip axial direction. Thus, the needle 201 performing the retraction action can enter the first space 104, and the needle 201 is stored in the first space 104 to prevent the needle 201 from being reused and causing biological contamination.

[0123] See Figure 1 , Figure 2The first space 104 extends along a first direction. The active component 301 is inserted into and can move along the first space 104. The first space 104 guides the movement of the active component 301 along the first direction, ensuring the stability of the movement. Before the active component 301 reaches the needle retraction position, the first space 104 stores the working part 501, the working part 502, and the needle 201. When the active component 301 reaches the needle retraction position, it gradually moves away from the first space 104 along the first direction, thereby increasing the space that the needle 201 can occupy within the first space 104. This allows the needle 201 to move freely within the first space 104, further preventing the reuse of the needle 201 after use. The first space 104 serves to guide the movement of the active component 301 and to collect used needles 201. Of course, the active component 301 can also be moved along the first direction and mounted on the main body 101 via a guide rail structure or other means.

[0124] By using elastic coupling to enable the needle 201 to perform the puncture action, the cost of the needle insertion unit can be reduced.

[0125] The method of using magnetic coupling to make the needle 201 perform the puncture action can obtain a larger needle insertion force by adjusting the distance between the working part 1 501 and the working part 2 502, thereby ensuring the puncture speed and puncture effect. This method has lower space requirements. Similarly, the method of using magnetic coupling to make the needle 201 perform the needle withdrawal action has lower space requirements for the inhaler. More components can be placed in a smaller space, which is beneficial to improving the space utilization of the inhaler.

[0126] By using the above-described method where the puncture action is performed by the needle 201 through magnetic force and / or elastic force, and the needle withdrawal action is performed by at least one of gravity, magnetic force, and elastic force, the user only needs to provide a force perpendicular to the needle insertion force and the needle withdrawal force to drive the active member 301 to move along the first direction. The force needs to counteract the needle insertion force and the needle withdrawal force. The user's hand strength will not affect the puncture action, ensuring the smooth progress of the puncture action. The operation is simple, and the structure is simple and easy to assemble.

[0127] The method of needle withdrawal in this application is not limited to the method described above, which uses gravity, elasticity, or magnetism to perform the needle withdrawal action. There are other methods as well, see [link to relevant documentation]. Figure 20 This will be discussed in detail below.

[0128] See Figure 20The active member 301 is also provided with a needle retraction protrusion 506; along a direction opposite to the first direction, the needle retraction protrusion 506 has a direction that gradually moves away from the drug reservoir 102 in the axial direction of the needle tip 202. The needle 201 is provided with a mating part 505 that is coupled to the needle retraction protrusion 506. The mating part 505 is provided on the side of the needle retraction protrusion 506 that is away from the drug reservoir 102 in the axial direction of the needle tip 202, and when the active member 301 is in the initial position, the mating part 505 is spaced apart from the needle retraction protrusion 506 in the axial direction of the needle tip 202. When the active component 301 moves from the initial position to the release position, the working part 501 drives the needle 201 to approach the medicine chamber 102 along the axial direction of the needle tip 202. The needle 201 performs a piercing action. The mating part 505 provided on the needle 201 moves along the axial direction of the needle tip 202 towards the medicine chamber 102. Finally, the mating part 505 reaches the needle retraction protrusion 506 and abuts against and connects with the needle retraction protrusion 506. Since the needle retraction protrusion 506 moves away from the drug reservoir 102 in the axial direction of the needle tip 202 in the opposite direction to the first direction, as the active member 301 continues to move in the first direction, the distance between the needle retraction protrusion 506 and the drug reservoir 102 in the axial direction of the needle tip 202 at the mating part 505 gradually increases. The mating part 505 is pushed away from the drug reservoir 102 by the needle retraction protrusion 506. Therefore, the needle retraction protrusion 506 causes the needle 201 with the mating part 505 to move away from the drug reservoir 102 in the axial direction of the needle tip 202, thereby reducing the distance between the working part 1 501 and the working part 2 502 in the axial direction of the needle tip. Under the guidance of the needle retraction protrusion 506, the needle 201 performs a needle retraction action, so that the needle tip 202 can be withdrawn from the drug carrier, so that the drug carrier forms a hole for the drug to leave, and the user can inhale the drug.

[0129] The working part 2 502 can also be fixedly connected to the main body 101 or the driving member 301. The needle retraction action of the needle 201 can also be realized by using the needle retraction protrusion 506 and the mating part 505. See Figure 21In the figure, the needle insertion spring 602 is fixedly connected to the needle 201 and the main body 101 respectively. When the active member 301 is in the initial position, the needle insertion spring 602 is stretched and undergoes elastic deformation, thus exerting elastic force. This shows the structure when the working part 2 502 is fixedly connected to the main body 101. When the active member 301 reaches the release position along the first direction, the blocking part 302 is disconnected from the first limiting part 203. Under the action of the working part 1 501 and the working part 2 502, the distance in the axial direction of the needle tip is... As the distance increases, the needle 201 performs a piercing action. The mating part 505 reaches the needle withdrawal protrusion 506 and abuts against it. As the driving member 301 continues to move in the first direction, the distance between the needle withdrawal protrusion 506 and the medicine tank 102 at the mating part 505 gradually increases axially from the needle tip 202. The mating part 505 is pushed away from the medicine tank 102 by the needle withdrawal protrusion 506, causing the needle 201 to overcome the tension of the needle insertion spring 602 and perform a needle withdrawal action. The needle withdrawal action of the needle 201 can be achieved by using the needle withdrawal protrusion 506 and the mating part 505 in both the working part one 501 and the working part two 502 to perform the piercing action through elastic coupling and magnetic coupling.

[0130] Those skilled in the art to which this application pertains will understand that the first direction described above is not limited to a straight line direction perpendicular to the axial direction of the needle tip 202, but can also be the direction in which the rotating member rotates around a rotation axis, the rotation axis of the first direction being parallel to the axial direction of the needle tip 202, and the rotation plane formed by the active member 301 rotating along the first direction being perpendicular to the axial direction of the needle tip.

[0131] See Figure 22 , Figure 23 The active component 301 is pivotally connected to the main body 101 via a pivot 306, see [reference]. Figure 22In Figure (a), the first direction is the direction in which the rotating member rotates around a rotation axis, and the rotation axis of the first direction is parallel to the axial direction of the needle tip. The axial direction of the rotating shaft 306 is parallel to the axial direction of the needle tip, and the first direction is the circumferential direction around the axis of the rotating shaft 306. The active mounting part 303 of the active member 301 extends along the first direction, and the active member 301 can move around the axis of the rotating shaft 306 in the first direction. Those skilled in the art to which this application pertains will understand that there are various ways to realize the pivotal connection between the active member 301 and the main body 101 via the pivot 306. For example, the pivot 306 may be fixedly connected to the active member 301, or rotatably connected to the main body 101. The pivot 306 may be able to rotate around its own axis, and the active member 301 may rotate around the axis of the pivot 306 in a first direction. Alternatively, the pivot 306 may be fixedly connected to the main body 101, and the active member 301 may be rotatably connected to the pivot 306. The active member 301 may be able to rotate relative to the pivot 306 in a first direction around the axis of the pivot 306, changing the position of the active member 301 relative to the needle 201 in the first direction. Of course, there are other ways to realize the rotation of the active member 301 around the axis of the pivot, which will not be described in detail here.

[0132] The first direction is the circumferential direction. When the active mounting part 303 rotates along the first direction, it passes through the release position and the needle retraction position in sequence along the first direction, so that the needle 201 performs the piercing action and the needle retraction action. The working principle of the needle 201 performing the piercing action and the needle retraction action is the same as the working principle when the first direction is the linear direction. The following is a brief description of the implementation method when the working part 1 501 and the working part 2 502 are elastically coupled through the needle insertion spring 601, so that the needle 201 performs the piercing action.

[0133] See Figure 22The needle spring 601 is sleeved on the needle rod 204 and is in a compressed state. The needle spring 601 is located between the active mounting part 303 of the active member 301 and the first limiting part 203 of the needle 201. One end of the needle spring 601 is regarded as the working part 2 502 and abuts against the active mounting part 303, and the other end is regarded as the working part 1 501 and abuts against the first limiting part 203. Since the active mounting part 303 can only rotate around the axis of the rotating shaft 306 in the first direction, the working part 2 502 can use the active mounting part 303 as a fulcrum and apply a force close to the medicine tank 102 to the working part 1 501 through the needle spring 601 which undergoes elastic deformation. When the active member 301 is in the initial position, the blocking part 302 of the active member 301 is connected to the first limiting part 203, preventing the first limiting part 203 from approaching the medicine chamber 102 under the action of the needle insertion spring 601, and preventing the working part 501 from driving the needle 201 to perform the piercing action; when the active mounting part 303 rotates in the first direction, the blocking part 302 of the active member 301 gradually disconnects from the first limiting part 203 of the needle 201, until the active member 301 reaches the release position, the blocking part 302 no longer restricts the needle 201 from approaching the medicine chamber 102 along the needle tip axial direction, so that the working part 501 pushes the needle 201 to perform the piercing action, and then the active member 301 reaches the needle retraction position, the needle 201 can be retracted by gravity, elasticity, magnetic force, or the pushing force applied by the needle retraction protrusion 506, so that the needle 201 performs the needle retraction action, which will not be described in detail here. Of course, when the first direction is the circumferential direction, the working part 1 501 and the working part 2 502 can also use other elastic coupling methods, or use magnetic coupling methods to apply the insertion force to the needle 201, so that the needle 201 performs the insertion action.

[0134] Those skilled in the art will understand that when this application uses elastic coupling, magnetic coupling, or the needle retraction protrusion 506 as a needle retraction structure to apply a needle retraction force to the needle 201, two needles can be provided in this application: needle 201, working part one 501, working part two 502, active mounting part 303, and needle retraction structure (needle retraction spring, needle retraction pressure spring, needle retraction magnetic attractor, needle retraction magnet). For example, see [link to relevant documentation]. Figure 24 In Figures (a) and (b), the two active mounting parts 303 are mounted on the same active component 301. Figure 24In Figure (b), two needles 201 are positioned opposite each other about the medicine container 102. Each needle 201 is connected to an insertion spring 601 and a retraction spring 607. Thus, when the active member 301 moves along the first direction, the two needles 201 can perform a piercing action through elastic coupling, and also perform a retraction action through elastic coupling. Alternatively, the two needles 201 can also perform a piercing action and a retraction action through magnetic coupling. When retracting the needle using gravity, the needle 201 needs to be vertically positioned and located below the medication chamber 102. When the drive member 301 moves to the retraction position and the working part 2 502, the needle 201, and the drive member 301 separate, a retraction force in the form of elasticity or magnetism is applied to the needle 201 to perform the retraction action. When using the inhaler, the needle 201 cannot be vertically positioned; the needle 201 can be vertically positioned above the medication chamber 102, or it can be horizontally positioned. The needle tip 202 can smoothly perform the retraction action under the action of a retraction force in the form of magnetism and / or elasticity.

[0135] In one embodiment of this application, see Figure 2 The main body 101 includes a storage cylinder 105 and a suction nozzle 401; the storage cylinder 105 contains a medicine compartment 102; the internal channel of the suction nozzle 401 contains a filter element 402. The filter element 402 can be a screen made of medical plastic or stainless steel. The filter element 402 is fixedly connected to the suction nozzle 401 by means of snap-fit ​​or heat fusion connection. The filter element 402 divides the internal channel of the suction nozzle 401 into a suction section 403 and a connecting section 404. The connecting section 404 is inserted into the storage cylinder 105. See [reference needed]. Figure 25 In Figures (a) and (b), the inner diameter of the connecting section 404 is equal to the outer diameter of the storage cylinder 105. The suction nozzle 401 can be fitted onto the storage cylinder 105 through the connecting section 404, and then the connecting section 404 and the storage cylinder 105 are fixedly connected by means of heat fusion, bonding, snap-fit, etc. During factory assembly, the drug carrier can be placed into the drug chamber 102 provided in the storage cylinder 105 first. Then, the storage cylinder 105 enters the connecting section 404. The filter element 402 partially seals the connection between the drug chamber 102 and the outside world. The drug carrier in the drug chamber 102 cannot enter the outside world through the filter holes of the filter element 402 and the suction nozzle 401, nor can it enter the main body 101 through the connecting hole 103. Therefore, the drug carrier is stored in the drug chamber 102 in a preset manner.

[0136] Furthermore, a first air passage 106 is provided through the side wall of the storage cylinder 105, connecting the outside to the drug compartment 102; a second air passage 405 is provided through the side wall of the connecting section 404; the connecting section 404 and the storage cylinder 105 are coaxially arranged and plugged into each other, and the first air passage 106 and the second air passage 405 are connected to form an air inlet 108 connecting the drug compartment 102 to the outside. The air inlet 108 is angled relative to the radial direction of the storage cylinder 105 within its cross-section. Airflow from the outside enters the drug compartment 102 through the air inlet 108, and under the guidance of the air inlet 108, it enters the drug compartment 102 in an offset manner, enhancing the driving effect of the airflow on the drug carrier. This will be described in detail below with reference to the accompanying drawings.

[0137] See Figure 25 In Figures (b) and (c), the first airway 106 and the second airway 405 are connected to form the air intake 108. See also... Figure 25 In Figure (c), when the drug carrier is placed in the drug chamber 102, the center of the drug carrier is located on the axis of the drug chamber 102 and the storage cylinder 105. Since the air inlet 108 is not parallel to the radial direction of the storage cylinder 105, but is set at an angle to it, the extension direction of the air inlet 108 does not pass through the center of the drug carrier, but is offset towards it. The airflow entering the drug chamber 102 from the outside through the air inlet 108 exerts a rotational force on the drug carrier, causing it to rotate within the drug chamber 102. This increases the degree of movement of the drug carrier, allowing the drug to leave the drug carrier as much as possible and enter the drug chamber 102, reducing drug residue within the drug carrier. See [reference needed]. Figure 25 In Figures (a) and (b), when the drug carrier is a capsule, the long axis of the capsule is coaxial with the storage cylinder 105 and the connecting section 404. The air inlet 108 is perpendicular to the long axis of the capsule and is set at an angle to the short axis of the capsule. When the user inhales through the mouthpiece 401, the outside air is biased and blown around the capsule under the guidance of the air inlet 108, so that the capsule rotates around the long axis, thereby allowing the drug to leave as much as possible.

[0138] Furthermore, the air intake duct 108 extends in a straight line at an angle to the radial direction of the storage cylinder 105 in the cross-section of the storage cylinder 105, ensuring that external airflow can quickly enter the drug chamber 102 and drive the drug carrier inside the drug chamber 102 to move.

[0139] To ensure accurate connection between the first air passage 106 and the second air passage 405, forming the air intake 108, see [reference needed]. Figure 25In Figure (a), when the connecting section 404 and the storage cylinder 105 are inserted and fitted, the length of the connecting section 404 is equal to that of the storage cylinder 105, thereby achieving axial limiting between the connecting section 404 and the storage cylinder 105 and ensuring that the projections of the first air passage 106 and the second air passage 405 on the axis of the storage cylinder 105 are at the same position. When the connecting section 404 is inserted into the storage cylinder 105, the outer diameter of the connecting section 404 is equal to the inner diameter of the storage cylinder 105, and when the storage cylinder 105 is inserted into the connecting section 404, the outer diameter of the storage cylinder 105 is equal to the inner diameter of the connecting section 404, thereby achieving radial limiting between the connecting section 404 and the storage cylinder 105, so that the first air passage 106 and the second air passage 405 can be tightly connected and communicated.

[0140] See Figure 25 In Figures (b) and (c), the inner wall of the connecting segment 404 is provided with a slot 406, which extends axially along the connecting segment 404 and communicates with the lower end of the connecting segment 404 (to...). Figure 25 (The direction in Figure (b) is illustrated schematically). The outer wall of the storage cylinder 105 is provided with an insert 107. The insert 107 extends axially along the storage cylinder 105. When the storage cylinder 105 is inserted into the connecting section 404, the lower end of the connecting section 404 is sleeved on the upper end of the storage cylinder 105. The insert 107 enters the slot 406 through the communication between the slot 406 and the lower end of the connecting section 404. The circumferential positional relationship between the storage cylinder 105 and the connecting section 404 is restricted by the slot 406 and the insert 107, thereby realizing the circumferential restriction between the storage cylinder 105 and the connecting section 404.

[0141] Through the axial, radial, and circumferential limiting of the connecting section 404 and the storage cylinder 105, the first air passage 106 and the second air passage 405 can be accurately aligned and connected to form the air intake passage 108, which facilitates assembly.
