Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medical devices, and particularly relates to a rotary cover type inhaler. BACKGROUND

[0002] At present, a powder inhaler for capsule type powder aerosol used in clinical application comprises a shell, a suction nozzle, a capsule chamber and a piercing needle capable of being inserted into the capsule chamber and piercing the capsule. When a patient uses the inhaler, the patient needs to place a medicine-containing capsule in the capsule chamber, then adjust a cover body covering the capsule chamber to a closed position, so that the capsule chamber is only in communication with an air inlet channel and the suction nozzle, and then press a button connected to the shell to drive the piercing needle to pierce into the capsule, and then make the piercing needle exit the capsule through a reset structure, the piercing needle pierces a hole on the capsule shell, and the medicine in the capsule can leave the capsule shell through the hole on the capsule, and then the patient can inhale the medicine through the suction nozzle.

[0003] When the patient uses the inhaler, the patient needs to place the capsule in the capsule chamber, close the capsule chamber, and then drive the piercing needle to pierce the capsule through the button, and the patient needs to perform multiple actions to inhale the medicine, which is inconvenient in use. SUMMARY

[0004] In order to simplify the steps of the patient using the dry powder inhaler, the application provides a rotary cover type inhaler.

[0005] The rotary cover type inhaler comprises a piercing needle, a box body provided with a capsule chamber, a cover body pivotally connected to the box body and a working piece, the piercing needle is slidably connected to the box body, and a matching part of the piercing needle is connected to the working piece; the working piece is elliptical, a straight line perpendicular to the working piece and passing through a center point of the working piece is a working axis, the cover body is connected to the working piece through a transmission mechanism, when the cover body rotates relative to the box body, the working piece is driven to rotate around the working axis, so that long axis end points and short axis end points of the working piece pass through the matching part in sequence, the piercing needle generates linear motion parallel to a rotating end surface of the working piece, the piercing needle is switched between a waiting position and a piercing position, and when the cover body is switched between an open position and a closed position, the piercing needle is switched from the waiting position to the piercing position and returns to the waiting position.

[0006] When the cover body rotates relative to the box body, the cover body can drive the elliptical working piece to rotate around the working axis, so that the piercing needle can be switched between the waiting position and the piercing position, after the piercing needle pierces a capsule shell in the capsule chamber, the piercing needle exits the capsule, the medicine in the capsule can leave the capsule through a hole on the capsule, and then the patient can inhale the medicine through the suction nozzle.

[0007] Because the working part is elliptical, it has two major axis endpoints and two minor axis endpoints. When the working part rotates 360° around the working axis in one direction, the two major axis endpoints and the two minor axis endpoints can connect with the mating part once each. The needle can move from the waiting position to the puncture position, then return to the waiting position, then move to the puncture position again, and finally return to the waiting position. When the working part rotates one revolution in one direction, the needle can reach the puncture position twice, ensuring the puncture effect of the needle on the capsule.

[0008] In one embodiment of this application, the rotary inhaler is provided with two opposing needles, and the mating parts of the two needles are respectively connected to the working part.

[0009] Since the two needles are positioned opposite each other about the capsule chamber and the working piece is elliptical, when the working piece rotates, the two needles can simultaneously move closer to or further away from the capsule chamber. With one working piece and two needles, the two needles can simultaneously pierce the capsule or exit from the capsule.

[0010] In one embodiment of this application, the working part is annular, and the needle is connected to the box body through an elastic element. Under the action of the elastic element, the mating part abuts against the inner wall of the working part.

[0011] In one embodiment of this application, the working part is annular, and the needle is connected to the box body through an elastic element. Under the action of the elastic element, the mating part abuts against the outer wall of the working part.

[0012] In one embodiment of this application, the workpiece is provided with a guide portion along its extension direction, and the mating portion is slidably connected to the guide portion, and the mating portion is capable of moving along the extension direction of the workpiece.

[0013] In one embodiment of this application, the movement path of the tip of the needle is parallel to the rotating end face of the workpiece.

[0014] When the movement path of the needle tip is not parallel to the rotating end face of the workpiece, the needle tip relies on a component of the force exerted on it by the workpiece to move along its movement path. However, when the movement path of the needle tip is parallel to the rotating end face of the workpiece, the workpiece can directly exert a force on the needle that is collinear with the movement path of the needle tip, thus making the movement of the needle tip smoother.

[0015] In one embodiment of this application, the rotating end face of the cover is parallel to the rotating end face of the working part.

[0016] Since the rotating end surface of the cover body is parallel to the rotating end surface of the working piece, the transmission mechanism does not need to be provided with a reversing mechanism to realize the transmission between the cover body and the working piece, thereby simplifying the transmission structure.

[0017] In an embodiment of the present application, the transmission mechanism is a gear set, the cover body, the working piece and the gears in the gear set are engaged, and the rotating end surface of the working piece is parallel to the rotating end surface of the gears in the gear set.

[0018] In an embodiment of the present application, the length direction of the capsule bin is parallel to the rotating end surface of the working piece.

[0019] In an embodiment of the present application, the length direction of the capsule bin is perpendicular to the rotating end surface of the working piece.

[0020] The present application has at least the following beneficial effects:

[0021] 1. When the cover body rotates relative to the box body, the cover body can drive the oval-shaped working piece to rotate around the working axis, so that the lancet can switch between the waiting position and the puncture position. After the lancet punctures the capsule shell in the capsule bin, the capsule is withdrawn, the medicine in the capsule can exit the capsule through the hole on the capsule, and then the patient can inhale the medicine through the suction nozzle.

[0022] 2. Because the working piece is oval-shaped, the working piece has two long axis end points and two short axis end points. When the working piece rotates 360° around the working axis in one direction, the two long axis end points and the two short axis end points of the working piece can be connected to the matching part once, respectively. The lancet can reach the puncture position from the waiting position, and then return to the waiting position, and then reach the puncture position again, and finally return to the waiting position. The working piece rotates one circle in one direction, and the lancet can reach the puncture position twice to ensure the puncture effect of the lancet on the capsule.

[0023] 3. Since the rotating end surface of the cover body is parallel to the rotating end surface of the working piece, the transmission mechanism does not need to be provided with a reversing mechanism to realize the transmission between the cover body and the working piece, thereby simplifying the transmission structure.

[0045] In order to have a clearer understanding of the technical features, objectives and effects of the present application, the specific embodiments of the present application will be described with reference to the drawings, in which the same reference numerals represent the same or similar parts having the same function.

[0046] In this document, "schematic" means "serving as an example, illustration or explanation", and any illustration, embodiment described as "schematic" in this document should not be interpreted as a more preferred or more advantageous technical solution.

[0047] In order to make the drawings simple, only the parts related to the present application are schematically shown in the drawings, which do not represent the actual structure of the product. In addition, in order to make the drawings simple and easy to understand, in some drawings, only one of the parts having the same structure or function is schematically shown, or only one of them is marked.

[0048] Please refer to Figures 1 to 17 to understand the present application.

[0049] Please refer to Figure 1 , a rotating cover inhaler, which comprises a lancet 205, a box body 301 provided with a capsule holder 302, a cover 101 and a working member 201 pivotally connected with the box body 301, the cover 101 can move relative to the box body 301 between an open position and a closed position, and the working member 201 is elliptical.

[0050] The lancet 205 is slidingly connected with the box body 301, the capsule holder 302 is provided with a hole for the lancet 205 to enter and exit, the lancet 205 can move linearly in a direction to enter the capsule holder 302 to pierce the capsule shell in the capsule holder 302, and then the lancet 205 exits the capsule holder 302, so that the medicine in the capsule enters the capsule holder 302 through the hole in the capsule shell, external air can enter the capsule holder 302 through the air inlet 303, and the user can suck the medicine through the mouthpiece 102.

[0051] The straight line perpendicular to the working piece 201 and passing through the center point of the working piece 201 is the working axis, the working piece 201 is pivotally connected with the box body 301, the working piece 201 can rotate around the working axis, and the cover body 101 is connected with the working piece 201 through a transmission mechanism.

[0052] Referring to Figures 1 to 3 , the cover body 101 is connected with the working piece 201 through a gear set, the cover body 101 is fixedly connected with the first transmission shaft 104, the first transmission shaft 104 is coaxially and fixedly connected with the first gear 103, the first gear 103 is engaged with the second gear 204, and the second gear 204 is fixedly connected with the working piece 201, when the cover body 101 rotates relative to the box body 301, the cover body 101 drives the working piece 201 to rotate around the working axis through the gear set.

[0053] Since the working piece 201 is in an elliptical shape, the working piece 201 has a major axis and a minor axis, the length of the minor axis is less than the length of the major axis, and thus the distance from the minor axis end point 203 to the center point of the working piece 201 is less than the distance from the major axis end point 202 to the center point of the working piece 201.

[0054] The fitting part 206 of the lancet 205 is connected with the working piece 201, in an embodiment of the present application, the working piece 201 is annular, the lancet 205 is further connected with the box body 301 through an elastic member 207, the elastic member 207 can be a spring, rubber or other elastic structure, under the action of the elastic member 207, the fitting part 206 abuts against the inner wall of the working piece 201.

[0055] Hereinafter, an example when the cover body 101 moves from the open position to the closed position is described.

[0056] Referring to Figure 2 , Figure 4 , the projection of the capsule bin 302 on the rotating end face of the working piece is located within the range of the rotating path of the working piece 201, when the cover body 101 is in the open position, the capsule bin 302 is exposed to the outside, at this time, the major axis end point 202 of the working piece 201 is located at the fitting part 206 and abuts against the inner wall of the working piece 201, the lancet 205 is in the standby position, and the user can put the capsule into the capsule bin 302.

[0057] Subsequently, the user adjusts the cover body 101 from the open position to the closed position, referring to Figure 4 , Figure 5, the cover 101 drives the working member 201 to rotate around the working axis, so that the short axis end point 203 of the working member 201 moves towards the matching part 206, because the distance between the short axis end point 203 and the capsule chamber 302 is smaller than the distance between the long axis end point 202 and the capsule chamber 302, the matching part 206 abuts against the inner wall of the working member 201, and the length of the needle 205 is constant, when the short axis end point 203 rotates towards the matching part 206, the distance between the inner wall of the working member 201 and the capsule chamber 302 on the movement path of the needle tip decreases, the elastic member 207 elastically deforms, the needle 205 generates linear movement parallel to the rotating end face of the working member, so that the working member 201 drives the matching part 206 of the needle 205 to move towards the capsule chamber 302, the needle tip moves into the capsule chamber 302, until the short axis end point 203 reaches the matching part 206, the distance between the inner wall of the working member 201 and the capsule chamber 302 on the movement path of the needle tip is the shortest, see Figures 6 to 8 , the needle 205 reaches the puncture position, and the needle tip pierces into the capsule; then, the user continues to adjust the cover 101 towards the closed position, the short axis end point 203 moves away from the matching part 206, see Figure 9 , the other long axis end point 202 approaches the matching part 206, the distance between the inner wall of the working member 201 and the capsule chamber 302 on the movement path of the needle tip increases, the matching part 206 abuts against the inner wall of the working member 201 under the elastic force of the elastic member 207, the matching part 206 generates movement away from the capsule chamber 302, the needle tip gradually exits the capsule, until the long axis end point 202 reaches the matching part 206, see Figures 10 to 12 , the needle tip exits the capsule, the needle 205 returns to the waiting position, the cover 101 reaches the closed position, and the drug can enter the capsule chamber 302 through the hole on the capsule shell, and the user can use the suction nozzle 102 to smoke the drug.

[0058] When the cover 101 moves from the closed position to the open position, the movement process of the working member 201 and the needle 205 is similar to the process described above, which will not be repeated here.

[0059] Therefore, when the cover 101 switches between the open position and the closed position, the needle 205 can reach the puncture position from the waiting position and return to the waiting position.

[0060] Those skilled in the art to which the present application pertains can understand that the needle 205 in the present application is not limited to being in the waiting position only when the long axis end point 202 reaches the matching part 206, but when the matching part 206 switches from being in contact with the short axis end point 203 to being in contact with a certain section between the long axis end point 202 and the short axis end point 203, the needle 205 can move away from the capsule chamber 302, in short, the matching part 206 can also be in the waiting position when it is connected with a certain section between the long axis end point 202 and the short axis end point 203, so that the tip of the needle 205 can exit the capsule.

[0061] Those skilled in the art of the present application can understand that the connection relationship between the fitting part 206 and the working piece 201 is not limited to the mode that the fitting part 206 abuts against the inner wall of the working piece 201 under the action of the elastic piece 207, but can also have other modes. For example, in an embodiment of the present application, the working piece 201 is annular, the lancet 205 is also connected with the box body 301 through the elastic piece 207, and under the action of the elastic piece 207, the fitting part 206 abuts against the outer wall of the working piece 201. Referring to Figure 13 , the projection of the capsule container 302 on the rotating end surface of the working piece is located within the range of the rotating path of the working piece 201, when the long axis end point 202 moves to the fitting part 206, the fitting part 206 is driven away from the capsule container 302 by the working piece 201 against the force of the elastic piece 207, and is in the waiting position; when the short axis end point 203 moves to the fitting part 206, the fitting part 206 is close to the capsule container 302 under the action of the elastic piece 207, reaches the puncture position, and can puncture the capsule in the capsule container 302.

[0062] Alternatively, referring to Figure 14 , Figure 15 , the projection of the capsule container 302 on the rotating end surface of the working piece is located within the range of the rotating path of the working piece 201, in an embodiment of the present application, the working piece 201 is provided with a guide part along the extension direction thereof, the fitting part 206 is slidingly connected with the guide part, and when the working piece 201 rotates relative to the fitting part 206 around the working axis, the contact position of the fitting part 206 with the working piece 201 changes, so that due to the elliptical shape of the working piece 201, the position of the working axis relative to the capsule container 302 does not change, and under the guiding action of the working piece 201, the working piece 201 drives the fitting part 206 to approach or move away from the capsule container 302, so that the lancet 205 switches between the waiting position and the puncture position. There are various modes to realize the sliding connection between the guide part and the fitting part 206, for example, referring to Figure 14 , Figure 15 , the fitting part 206 is two spaced apart cylinders, the working piece 201 can enter between the two cylinders, and the working piece 201 can rotate relative to the two cylinders, so that the working piece 201 can drive the lancet 205 to move linearly when the working piece 201 rotates; alternatively, the fitting part 206 is a cylinder, and the guide part is a guide groove, the fitting part 206 is inserted into the guide part, which will not be described here.

[0063] In one embodiment of the present application, the movement path of the tip of the lancet 205 is parallel to the rotating end surface of the workpiece 201, the lancet 205 is inclined relative to the rotating end surface of the workpiece 201, and when the movement path of the tip of the lancet 205 is not parallel to the rotating end surface of the workpiece 201, the tip of the lancet moves along its movement path depending on the component force of the force exerted on the tip of the lancet by the workpiece 201, and through the way that the movement path of the tip of the lancet is parallel to the rotating end surface of the workpiece 201, the workpiece 201 can directly exert the force on the lancet 205 that is collinear with the movement path of the tip of the lancet, so that the movement of the tip of the lancet is smoother, and preferably, the movement path of the tip of the lancet is arranged on the rotating end surface of the workpiece 201.

[0064] Of course, the movement path of the tip of the lancet can be inclined relative to the rotating end surface of the workpiece 201, and the movement of the lancet 205 can be decomposed, and the tip of the lancet can generate a straight line movement that is parallel to the rotating end surface and can approach or move away from the capsule bin 302.

[0065] Referring to Figure 1 , Figure 3 , Figure 5 In one embodiment of the present application, the rotating end surface of the cover 101 is parallel to the rotating end surface of the workpiece 201.

[0066] Since the rotating end surface of the cover 101 is parallel to the rotating end surface of the workpiece 201, relative to the rotating end surface of the cover 101 that is not parallel to the rotating end surface of the workpiece 201, such as the way that the rotating end surface of the cover 101 is perpendicular to the rotating end surface of the workpiece 201, the transmission mechanism does not need to be provided with a reversing mechanism to realize the transmission between the cover 101 and the workpiece 201, thereby simplifying the transmission structure and reducing the occupied space of the transmission mechanism.

[0067] Of course, the rotating end surface of the cover 101 can also be perpendicular to the rotating end surface of the workpiece 201, but a reversing mechanism such as a worm gear mechanism is needed to realize the rotation of the workpiece 201 driven by the cover 101, which will not be described here.

[0068] Further, in one embodiment of the present application, the rotating end surface of the cover 101 is parallel to the rotating end surface of the workpiece 201, and the transmission mechanism is a gear set, the cover 101 and the workpiece 201 are engaged with the gears in the gear set, the rotating end surface of the workpiece 201 is parallel to the rotating end surface of the gears in the gear set, the structure of the transmission mechanism is simple, and the occupied space of the transmission mechanism is reduced.

[0069] Those skilled in the art to which the present application pertains can understand that the transmission mechanism in the present application is not limited to the way of the gear set, but can also be a connecting rod mechanism cooperating with a gear, or the cover 101 drives the workpiece 201 to move through a belt transmission, which will not be described here.

[0070] Referring to Figures 1 to 6 In an embodiment of the present application, the length direction of the capsule compartment 302 is parallel to the rotating end surface of the working member 201, and when the capsule is placed in the capsule compartment 302, the length direction of the capsule is parallel to the length direction of the capsule compartment 302, so that the capsule can be placed parallel to the rotating end surface of the working member 201. The position and orientation of the piercing needle 205 are set so that the movement path of the tip of the piercing needle 205 is parallel to or perpendicular to the length direction of the capsule compartment, and the tip of the piercing needle 205 can pierce the end or side wall of the capsule to meet different use requirements.

[0071] Of course, the capsule compartment can also be set in other ways, referring to Figure 16 In an embodiment of the present application, the length direction of the capsule compartment 302 can also be perpendicular to the rotating end surface of the working member 201, and when the piercing needle 205 moves parallel to the rotating end surface of the working member, it can pierce the capsule to meet different use requirements.

[0072] Referring to Figures 1 to 6 In an embodiment of the present application, the turn cap inhaler is provided with two oppositely arranged piercing needles 205, and the fitting parts 206 of the two piercing needles 205 are respectively connected with the working member 201. The projection of the capsule compartment 302 on the rotating end surface of the working member is located within the range of the rotating path of the working member 201 and between the two piercing needles 205. Since the oval-shaped working member 201 has symmetry, when the working member 201 rotates, the two piercing needles 205 can simultaneously approach or move away from the capsule compartment 302. Through the mode of one working member 201 and two piercing needles 205, the two piercing needles 205 can simultaneously pierce the capsule or withdraw from the capsule, ensuring the stability of the capsule when it is subjected to the force of the piercing needle 205 and ensuring the successful achievement of the purpose of piercing the capsule.

[0073] The arrangement mode of the two piercing needles 205 is not limited to the opposite arrangement mode, but can also be that the projection of the two piercing needles 205 on the rotating end surface of the working member and the line connecting the center point of the working member 201 are arranged at an angle. For example, the line connecting one piercing needle 205 and the center point of the working member 201 is a first straight line, the line connecting the other piercing needle 205 and the center point of the working member 201 is a second straight line, and the included angle between the first straight line and the second straight line is 90°, so that the two piercing needles 205 can have different states to achieve different medication purposes.

[0074] Those skilled in the art to which the present application belongs can understand that the position of the capsule compartment 302 in the present application is not limited to the mode in which the projection of the capsule compartment 302 on the rotating end surface of the working member is located within the range of the rotating path of the working member 201, but can also be that the projection of the capsule compartment 302 on the rotating end surface of the working member is located outside the range of the rotating path of the working member 201, referring to Figure 17When the long axis end point 202 moves towards the matching part 206, the distance between the inner wall of the working piece 201 and the capsule container 302 on the movement path of the needle tip decreases, the needle 205 approaches the capsule container 302, and reaches the puncture position; when the short axis end point 203 moves towards the matching part 206, the distance between the inner wall of the working piece 201 and the capsule container 302 on the movement path of the needle tip increases, the needle 205 moves away from the capsule container 302, and reaches the waiting position, so that when the long axis end point 202 reaches the matching part 206, the needle 205 is in the puncture position, and when the short axis end point 203 reaches the matching part 206, the needle 205 is in the waiting position. Different from the situation that the projection of the capsule container 302 on the rotating end surface of the working piece is located within the rotating path of the working piece 201, the details are not repeated here.

[0075] Referring to Figure 17 When the rotating cap inhaler is provided with two oppositely arranged needles 205, the matching parts 206 of the two needles 205 are respectively connected with the working piece 201, the capsule container 302 is provided with two, and the two capsule containers 302 are oppositely arranged, the projection of the capsule container 302 on the rotating end surface of the working piece is located outside the rotating path of the working piece 201, when the long axis end point 202 moves towards the matching part 206, the two needles 205 can simultaneously puncture the capsules in the two capsule containers 302, and the drugs in the two capsules can be different, so that when the two capsules are simultaneously punctured, different medication purposes can be achieved.

[0076] The parameters of the transmission mechanism can be set so that the rotating angle of the cover body 101 is the same as or different from the rotating angle of the working piece 201. For example, when the cover body 101 needs to be switched from the open position to the closed position by rotating 180°, the working piece 201 can also rotate 180°, the needle 205 can reach the puncture position from the waiting position and return to the waiting position, or the cover body rotates 180° and the working piece 201 rotates 360°. Since the working piece 201 is elliptical, the working piece 201 has two long axis end points 202 and two short axis end points 203. When the working piece 201 rotates one circle around the working axis in one direction, the two end points of the working piece 201 can be connected with the matching part 206 once, respectively, the needle 205 can reach the puncture position from the waiting position, and then return to the waiting position, and then reach the puncture position again, and finally return to the waiting position. When the working piece 201 rotates one circle in one direction, the needle 205 can reach the puncture position twice, which ensures the puncture effect of the needle 205 on the capsule.
