[0001] CONTINUOUS CAPSUUE INHAEATION DEVICE

[0002] Cross Reference to Related Applications

[0003] This application claims priority to CN Application No. 202411573450.X, filed November 6, 2024, the disclosure of which is incorporated herein by reference in its entirety.

[0004] Technical Field

[0005] The present invention relates to the field of medical device technologies, and in particular to a continuous capsule inhalation device.

[0006] Background

[0007] Oral inhalation preparations have unique advantages in treatment of respiratory diseases such as asthma and chronic obstructive pulmonary disease, for example, rapid onset of action, good targeting, low dosage, few side effects, no hepatic first-pass effect, high bioavailability, and good compliance.

[0008] Oral inhalation preparations are mainly classified into three categories: nebulizer solutions (Nebulizers), metered-dose inhalers (MDIs), and dry powder inhalers (DPIs, also known as powder inhalers). The DPI is a new dosage form developed on the basis of MDI, and requires the use of a special inhalation device pre-loaded with a micronized drug or a drug mixed with a carrier. Upon patient inhalation, the drug is entrained in the airflow and passes through specially designed airflow channels within the device. These channels facilitate dispersion of the drug into fine particles with aerodynamic diameters of 1 to 5 micrometers, enabling deposition in the lower respiratory tract to exert localized or systemic therapeutic effects. The DPI has effectively overcome shortcomings of the nebulizer such as poor portability, imprecise dosage, high hand-mouth coordination requirement, and inhalation irritation.

[0009] The mainstream DPIs on the market can be classified into capsule type, reservoir type, and blister type according to the form of micronized drug containment. The capsule type is more complicated to use and requires carrying extra capsules. Not only is the hygiene during the capsule transfer process into the device uncontrollable, but the subsequent disposal of used capsules also presents an inconvenience. Summary of the Invention

[0031] Detailed Description

[0032] The technical solutions in the present invention will be described clearly and completely through the accompanying drawings. Apparently, the described embodiments are a part of embodiments of the present invention, instead of all embodiments. Based on the embodiments of the present invention, all other embodiments derived by those of ordinary skill in the art without any creative effort shall fall within the protection scope of the present invention.

[0033] The present invention will be further described with reference to the accompanying drawings. As shown in FIG. 1 to FIG. 8, a continuous capsule inhalation device provided in this embodiment includes: a main frame 1, where a bottom end of the main frame 1 is provided with an accommodating chamber 12 for accommodating a capsule driving wheel 11, and the capsule driving wheel 11 is formed with a plurality of capsule accommodating slots 13; a mouthpiece 2, where the mouthpiece 2 is located at a top end of the main frame 1 and is in communication with the accommodating chamber 12; and a button-type piercing assembly 3 and a rotating assembly 4, where the button-type piercing assembly 3 and the rotating assembly 4 are mounted at the bottom end of the main frame 1, and the accommodating chamber 12 is located between the button-type piercing assembly 3 and the rotating assembly 4, the rotating assembly 4 drives the capsule driving wheel 11 in the accommodating chamber 12 to rotate at equal angles, thereby transporting a capsule in each capsule accommodating slot 13 to a first position close to the mouthpiece 2, and the button-type piercing assembly 3 pierces a shell of the capsule located at the first position.

[0034] The above technical solution has the following working principle and beneficial effects:

[0035] In the continuous capsule inhalation device provided in the present invention, each capsule accommodating slot 13 formed on the capsule driving wheel 11 is loaded with a capsule. During use, a user applies a force to press the button-type piercing assembly 3, and the button-type piercing assembly 3 pierces the shell of the capsule located in the first position. After the force is released from pressing the button-type piercing assembly 3, in a process that the button-type piercing assembly 3 is reset, a knob assembly 4 drives the accommodating capsule driving wheel 11 in the accommodating chamber 12 to rotate, and the capsule driving wheel 11 transports the pierced capsule to a position below the mouthpiece 2, while a non-pierced capsule continues to be sent to the first position and waits for use, at which time the user can inhale through the mouthpiece. The continuous capsule inhalation device disclosed in the present invention is easy to carry and can achieve storage and sequential inhalation of a plurality of capsules in a single operation, without carrying capsules additionally. Each press of the button-type piercing assembly 3 pierces an individual capsule for inhalation, thus eliminating the need for reloading after each use.

[0036] In one embodiment, the capsule driving wheel 11 is rotatably mounted in the accommodating chamber 12, and eight capsule accommodating slots 13 are formed on the capsule driving wheel 11.

[0037] The above technical solution has the following working principle and beneficial effects:

[0038] The eight capsule accommodating slots 13 are formed on the capsule driving wheel 11, so that eight capsules can be stored at a time. Each time the button-type piercing assembly 3 is pressed, the piercing and inhalation of one capsule can be completed. After the eight capsules have been inhaled, they can be replaced with eight new ones.

[0039] In one embodiment, the button-type piercing assembly 3 includes: a main shell 31, where the main shell 31 is mounted on the bottom end of the main frame 1, and the accommodating chamber 12 is located in the main shell 31; a button body 32, where the button body 32 is mounted on a side end of the main shell 31 ; a first spring 33, where the first spring 33 abuts against the button body 32 and the accommodating chamber 12 respectively; and a main pin 34, where the main pin 34 is mounted on the button body 32, and a side opening 35 is reserved on the accommodating chamber 12 for the main pin 34 to pierce the first position.

[0040] The above technical solution has the following working principle and beneficial effects:

[0041] During use, the user applies a force to press the button body 32, and the button body 32 moves in a contraction direction of the first spring 33. The main pin 34 mounted on the button body 32 penetrates into the first position from the side opening 35, thereby completing the piercing of the shell of the capsule located at the first position. After the force applied to the button-type piercing assembly 3 is released, the button body 32 is reset as the first spring 33 resets.

[0042] In one embodiment, the rotating assembly 4 includes: a side cover 41, where the side cover 41 is mounted on the bottom end of the main frame 1 and clamped on the main shell 31 at an end away from the button body 32, and an end of the accommodating chamber 12 near the side cover 41 is open; a pressing plate 42, where the pressing plate 42 is located in the side cover 41 and abuts against the capsule driving wheel 11, two side cover pins 43 penetrating the pressing plate 42 are mounted on an inner wall of the side cover 41, and one of the side cover pins 43 is arranged opposite to the main pin 34 and used to pierce the shell of the capsule; a second spring 44, where the second spring 44 abuts against the inner wall of the side cover 41 and the pressing plate 42 respectively; and a rotator 45, where a center end of the capsule driving wheel 11 is provided with an inner channel for facilitating passage of the rotor 45, and a surface of the rotor 45 is provided with a plurality of outer ribs 46 for being clamped on an inner wall of the inner channel, one end of the rotor 45 abuts against the button body 32, and the other end of the rotor 45 is provided with eight teeth 47 distributed in a circular array, one end of the pressing plate 42 close to the capsule driving wheel 11 is provided with an inner groove for accommodating the other end of the rotor 45, four wedge clamp blocks 48 adapted to the teeth 47 are distributed in a circular array at a groove bottom end of the inner groove, and eight wedge clamp rods 49 adapted to the wedge clamp blocks 48 are distributed in a circular array at an end of the capsule driving wheel 11 close to the pressing plate 42.

[0043] The teeth 47 each have a double bevel, and both the wedge clamp blocks 48 and the wedge clamp rods 49 each have a single bevel.

[0044] The above technical solution has the following working principle and beneficial effects:

[0045] After opening the side cover 41, the user fills eight capsules into the eight capsule accommodating slots 13 of the capsule driving wheel 11 and covers the side cover 41. After the eight capsules are used up, the capsule shells are ejected, and eight new capsules are reloaded.

[0046] During use, the user applies a force to press the button body 32, and the button body 32 moves in the contraction direction of the first spring 33. The main pin 34 mounted on the button body 32 penetrates into the first position from the side opening 35 and presses against the shell of the capsule. The capsule presses against the pressing plate 42 in the capsule accommodating slot 13, and then the button body 32 presses against the rotor 45, thereby sending the rotor 45 into the inner groove. Bevel ends of four of the eight teeth 47 press against bevel ends of the wedge clamp blocks 48. Because non-bevel ends of four of the eight wedge clamp rods 49 and non-bevel ends of the wedge clamp blocks 48 are restrained by each other (as shown in the state of FIG. 7), the rotor 45 cannot drive the capsule driving wheel 11 to rotate. The rotor 45 presses the pressing plate 42 to move along the side cover pin 43 in a contraction direction of the second spring 44. The side cover pin 43 protrudes from the pressing plate 42, thereby cooperating with the main pin 34 to pierce both ends of the shell of the capsule located in the capsule accommodating slot 13. After the non- bevel ends of the wedge clamp rods 49 disengage from the non-bevel ends of the wedge clamp blocks 48, the two lose the tendency to restrain each other. As the rotor 45 further presses the pressing plate 42, the bevel ends of the teeth 47 further press against the bevel ends of the wedge clamp blocks 48. The pressing plate 42 cannot rotate under the limitation of the two side cover pins 43. The teeth 47 can only drive the rotor 45 and the capsule driving wheel 11 connected to the rotor 45 to rotate at a small angle. The capsule driving wheel 11 drives the capsule in a pierced state to displace slightly. The side cover pin 43 and the main pin 34 form a pull on the shell of the capsule to further destroy the shell of the capsule. Moreover, due to the small-angle rotation of the capsule driving wheel 11, the non-bevel ends of the wedge clamp rods 49 connected to the rotor 45 pass over the non-bevel ends of the wedge clamp blocks 48, thereby completing the destruction of the shell of the capsule.

[0047] Then, the force applied to press the button body 32 is released. As the first spring 33 resets, the button body 32 is reset, and the main pin 34 is withdrawn from the first position from the side opening 35. After the rotor 45 loses the pressure of the button body 32, as the second spring 44 resets, the pressing plate 42 presses against the rotor 45 and retreats into the inner channel, and the side cover pin 43 returns to its original position. Because the non-bevel ends of the wedge clamp rods 49 connected to the rotor 45 pass over the non-bevel ends of the wedge clamp blocks 48 at this time, during the reset of the pressing plate 42, the bevel ends of the wedge clamp blocks 48 press against the bevel ends of the wedge clamp rods 49, thereby causing the capsule driving wheel 11 connected to the wedge clamp rods 49 to rotate again, and the capsule driving wheel 11 transports the pierced capsule to the position below the mouthpiece 2. After the pressing plate 42 presses against the capsule driving wheel 11 again, the non-bevel ends of the wedge clamp rods and the non-bevel ends of the wedge clamp blocks 48 resume the state of mutual restraint. Then, the user performs inhalation, and the capsule rises and rotates under the flow channel 5 under the influence of the airflow (this principle is a mature technology and is not the focus of the patent application), releasing the drug powder. After the user completes the inhalation, the capsule falls back into the capsule accommodating slot 13 under the influence of gravity. At this time, a capsule that has not been pierced continues to be sent to the first position and waits for use.

[0048] Specifically, when the user presses the button body 32 to advance to a first depth, the main pin 34 extends from the side opening 35 to the first position and presses against the capsule shell, while the capsule presses against the pressing plate 42 inside the capsule accommodating slot 13. When the user continues pressing the button body 32 to advance to a second depth, the button body 32 presses against the rotor 45, and the rotor 45 is sent into the inner groove. The bevel ends of four out of the eight teeth 47 then press against the bevel ends of the wedge clamp blocks 48, and the rotor 45 presses the pressing plate 42 to move along the side cover pin 43 in the contraction direction of the second spring 44. The side cover pin 43 extends out of the pressing plate 42, thereby cooperating with the main pin 34 to pierce both ends of the shell of the capsule located in the capsule accommodating slot 13. When the user further presses the button body 32 to advance to a third depth, the non-bevel ends of the wedge clamp rods 49 are detached from the non-bevel ends of the wedge clamp blocks 48, releasing their mutual restraint. The capsule driving wheel 11 is rotated by a small angle, the non-bevel ends of the wedge clamp rods 49 pass over the non-bevel ends of the wedge clamp blocks 48, and the side cover pin 43 and the main pin 34 form a pull on the shell of the capsule to further destroy the shell of the capsule. After the user releases the pressure on the button body 32, the main pin 34 and the side cover pin 43 are withdrawn from the shell of the capsule under the reset actions of the first spring 33 and the second spring 44. The bevel ends of the wedge clamp blocks 48 press against the bevel ends of the wedge clamp rods 49, causing the capsule driving wheel 11 connected to the wedge clamp rods 49 to rotate again. The capsule driving wheel 11 then conveys the pierced capsule to the position below the mouthpiece 2, allowing the user to inhale.

[0049] In one embodiment, an end of the rotor 45 close to the button body 32 is configured to be hemispherical shaped, an end of the rotator close to the pressing plate 42 is provided with a cavity for accommodating a central column 40, and the four wedge clamp blocks 48 are arranged in a circular array with the central column 40 as a center.

[0050] The above technical solution has the following working principle and beneficial effects:

[0051] The rotor 45 is sent into the inner groove, and the central column 40 is inserted into the cavity, so that the precise movement of the rotor 45 is achieved.

[0052] In one embodiment, a flow channel 5 with a filter is arranged in the mouthpiece 2, and an upper cover 6 for protecting the mouthpiece 2 is mounted on the main frame 1.

[0053] The working principle of the above technical solution is:

[0054] The user performs inhalation, and the capsule rises and rotates under the flow channel 5 under the influence of the airflow (this principle is a mature technology and is not the focus of the patent application), releasing the drug powder. The user then completes the inhalation.

[0055] As shown in FIG. 9, in one embodiment, the side cover pin 43 arranged opposite to the main pin 34 includes: a pin shaft 51 , where the pin shaft 51 is mounted on the side cover 41 , and a position-limiting sleeve 50 sleeved on the pin shaft 51 is mounted on the pressing plate 42; a pin head 52, where the pin head 52 is mounted on the pin shaft 51; an action chamber, where the action chamber is located in the pin shaft 51 and arranged close to the pin head 52, and a miniature screw 53 is rotatably mounted in the action chamber and connected to the pin head 52; a screw sleeve 54, where the screw sleeve 54 is sleeved on the miniature screw 53, and a miniature spring 55 is sleeved on the miniature screw 53 and abuts against an inner wall of the action chamber and the screw sleeve 54 respectively; and an outer thrust ring 56, where the outer thrust ring 56 is sleeved on the pin shaft 51, the outer thrust ring 56 is adapted to the position-limiting sleeve 50, a plurality of guide grooves 57 are circumferentially opened at a side end of the pin shaft 51, and guide blocks are slidably connected in the guide grooves 57 and connected to an inner ring of the outer thrust ring 56 and the screw sleeve 54.

[0056] The above technical solution has the following working principle and beneficial effects:

[0057] When the user presses the button body 32 to advance to a first depth, the main pin 34 extends from the side opening 35 to the first position and presses against the capsule shell, while the capsule presses against the pressing plate 42 inside the capsule accommodating slot 13. When the user continues pressing the button body 32 to advance to a second depth, the button body 32 presses against the rotor 45, and the rotor 45 is sent into the inner groove. The bevel ends of four out of the eight teeth 47 then press against the bevel ends of the wedge clamp blocks 48, and the rotor 45 presses the pressing plate 42 to move along the side cover pin 43 in the contraction direction of the second spring 44. The pin head 52 extends from the position-limiting sleeve 50, and the pin head 52 pierces the shell of the capsule. As the piercing depth of the pin head 52 increases, the positionlimiting sleeve 50 drives the outer thrust ring 56, a guide block connected to the outer thrust ring 56, and the screw sleeve 54 connected to the guide block to slide along the guide grooves 57. The screw sleeve 54 moves in the contraction direction of the miniature spring 55, and then drives the miniature screw 53 therein to rotate. The miniature screw 53 drives the pin head 52 to rotate, so as to improve the piercing efficiency.

[0058] In one embodiment, an outer wall of the outer thrust ring 56 is tapered inward towards the position-limiting sleeve 50, and a smaller-end of the outer thrust ring 56 is fitted into an inner ring of the position-limiting sleeve 50. In one embodiment, a rib 58 is provided on a side end of the pin head 52 near the miniature screw 53, and the rib 58 is fixedly mounted on the side end of the pin head 52 spirally.

[0059] The above technical solution has the following working principle and beneficial effects:

[0060] When rotating, the pin head 52 drives the rib 58 located thereon to rotate. The rib can expand a hole, so as to facilitate the pin head 52 to be withdrawn from the shell of the capsule.

[0061] Obviously, the above embodiments are merely examples for clear description and are not intended to limit the implementation. For those of ordinary skill in the art, changes or modifications in other different forms can be made based on the above description. It is unnecessary and impossible to list all implementations exhaustively here. Obvious changes or variations derived therefrom are still within the scope of protection of the present invention.
