Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a continuous capsule inhalation device. Background Art

[0002] Oral inhalation preparations have unique advantages in the treatment of respiratory diseases such as asthma and chronic obstructive pulmonary disease, such as rapid onset of action, good targeting, small dosage, few side effects, no first-pass effect in the liver, high bioavailability, and good compliance.

[0003] Oral inhalation preparations mainly include nebulizer inhalation solutions (Nebulizer), aerosols (MDI) and dry powder inhalation preparations (DPI, also known as powder inhalers). Dry powder inhalation preparations are new dosage forms developed on the basis of aerosols. They require the use of a special inhalation device, which contains micronized or carrier-mixed drugs. The drugs are inhaled along with the patient's airflow, and pass through the specially designed airflow channel inside the device and disperse the drugs as much as possible into microparticles with an aerodynamic particle size of 1-5 microns into the lower respiratory tract of the human body, thereby exerting a local or systemic effect. Dry powder inhalation preparations have overcome the shortcomings of nebulizer inhalation solutions, such as poor portability, inaccurate dosage, high hand-mouth coordination requirements for aerosol inhalation, and inhalation irritation.

[0004] The mainstream dry powder inhalation preparations on the market can be divided into capsule type, reservoir type and blister type according to the form of micronized drug loading. Among them, the capsule type is more complicated to use and requires extra capsules to be carried. Not only is the sanitary condition of the process of transferring the capsule to the inside of the device uncontrollable, but the subsequent disposal of the capsule is also a problem.

DETAILED DESCRIPTION

[0042] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] like Figures 1 to 8 As shown, this embodiment provides a continuous capsule inhalation device, comprising:

[0045] A main frame 1, wherein the bottom end of the main frame 1 has a receiving chamber 12 for receiving a capsule driving wheel 11, and a plurality of capsule receiving grooves 13 are formed on the capsule driving wheel 11;

[0046] A suction nozzle 2, which is located at the top of the main frame 1 and communicates with the receiving chamber 12;

[0047] A button-type puncture assembly 3 and a rotating assembly 4 are installed at the bottom end of the main frame 1, and the accommodating chamber 12 is located between the button-type puncture 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 the capsule in each capsule accommodating groove 13 to the first position close to the suction nozzle 2, and the button-type puncture assembly 3 punctures the shell of the capsule located at the first position.

[0048] The working principle and beneficial effects of the above technical solution are:

[0049] The present invention provides a continuous capsule inhalation device, wherein each capsule receiving groove 13 formed on the capsule driving wheel 11 is filled with a capsule, and when the patient uses the device, after applying force to press the button-type puncture assembly 3, the button-type puncture assembly 3 punctures the shell of the capsule located at the first position, and after the force is released to press the button-type puncture assembly 3, during the process of resetting the button-type puncture assembly 3, the rotating assembly 4 drives the capsule receiving driving wheel 11 in the receiving chamber 12 to rotate, and the capsule driving wheel 11 transports the punctured capsule to the bottom of the suction nozzle 2, while the unpunctured capsule continues to be sent to the first position to wait, and the user can inhale it through the suction nozzle at this time. The continuous capsule inhalation device disclosed by the present invention is easy to carry, and can complete the storage and inhalation of multiple capsules at one time, without the need to carry additional capsules, and after pressing the button-type puncture assembly 3 each time, each capsule is punctured and then inhaled, and there is no need to apply medicine every time.

[0050] In one embodiment, the capsule driving wheel 11 is rotatably installed in the accommodating chamber 12 , and eight capsule accommodating grooves 13 are formed on the capsule driving wheel 11 .

[0051] The working principle and beneficial effects of the above technical solution are:

[0052] The capsule driving wheel 11 is formed with eight capsule accommodating grooves 13, so that eight capsules can be stored at one time. Each time the button-type puncture assembly 3 is pressed, the puncture and suction of each capsule can be completed. After eight capsules are sucked, eight new capsules can be replaced.

[0053] In one embodiment, the button-type puncture assembly 3 comprises:

[0054] The main body shell 31 is installed at the bottom end of the main body bracket 1, and the receiving chamber 12 is located in the main body shell 31;

[0055] A button body 32, which is mounted on a side end of the main housing 31;

[0056] A spring 1 33, the spring 1 33 is disposed between the button body 32 and the receiving chamber 12;

[0057] The main body needle 34 is installed on the button body 32, and a side opening 35 is reserved on the accommodating chamber 12 for the main body needle 34 to penetrate into the first position.

[0058] The working principle and beneficial effects of the above technical solution are:

[0059] When the patient uses the medicine, he applies force to press the button body 32, and the button body 32 moves in the contraction direction of the spring 1 33. The main needle 34 installed on the button body 32 penetrates into the first position from the side opening 35, thereby completing the puncture of the shell of the capsule located at the first position. After the force of pressing the button-type puncture assembly 3 is released, the button body 32 is reset under the reset of the spring 1 33.

[0060] In one embodiment, the rotating assembly 4 comprises:

[0061] The side cover 41 is mounted on the bottom end of the main frame 1 and is clamped on the end of the main shell 31 away from the button body 32. The accommodating chamber 12 is open near the end of the side cover 41.

[0062] A pressing plate 42, the pressing plate 42 is located inside the side cover 41 and is disposed against the capsule driving wheel 11. Two side cover needles 43 are installed on the inner wall of the side cover 41 and penetrate the pressing plate 42. One of the side cover needles 43 is disposed opposite to the main body needle 34 and is used to puncture the capsule shell;

[0063] A second spring 44, the second spring 44 is disposed between the inner wall of the side cover 41 and the pressure plate 42;

[0064] The rotor 45 and the capsule driving wheel 11 are provided with an inner channel at the center end thereof for the rotor 45 to pass through. The surface of the rotor 45 is provided with a plurality of outer ribs 46 for being clamped on the inner wall of the inner channel. One end of the rotor 45 is abutted against the button body 32. The other end of the rotor 45 is provided with eight teeth 47 in a circular array. The end of the pressing plate 42 near the capsule driving wheel 11 is provided with an inner groove for accommodating the other end of the rotor 45. The bottom end of the inner groove is provided with four wedge-shaped clamping blocks 48 adapted to the teeth 47 in a circular array. The end of the capsule driving wheel 11 near the pressing plate 42 is provided with eight wedge-shaped clamping rods 49 adapted to the wedge-shaped clamping blocks 48 in a circular array.

[0065] The teeth 47 are double-beveled surfaces, and the wedge-shaped clamping block 48 and the wedge-shaped clamping rod 49 are both single-beveled surfaces.

[0066] The working principle and beneficial effects of the above technical solution are:

[0067] After the patient opens the side cover 41, he fills eight capsules into the eight capsule receiving slots 13 of the capsule driving wheel 11, and then covers the side cover 41 again. After the eight capsules are used up, the capsule housing is returned and eight capsules are filled again.

[0068] When the patient uses the medicine, he applies force to press the button body 32, and the button body 32 moves in the contraction direction of the spring 1 33. The main needle 34 installed 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 receiving groove 13. Then the button body 32 presses against the rotor 45, so that the rotor 45 is sent into the inner groove. The inclined ends of four of the eight teeth 47 press against the inclined ends of the wedge-shaped clamping block 48, and because the non-inclined ends of four of the eight wedge-shaped clamping rods 49 and the non-inclined ends of the wedge-shaped clamping block 48 are mutually restrained (such as Figure 7 In the state shown in the figure, the rotor 45 cannot drive the capsule driving wheel 11 to rotate, and the rotor 45 presses the pressing plate 42 to move along the side cover needle 43 in the contraction direction of the spring 2 44, and the side cover needle 43 protrudes out of the pressing plate 42, thereby completing the puncture of the two ends of the shell of the capsule located in the capsule receiving groove 13 with the main body needle 34. After the non-bevel end of the wedge-shaped clamping rod 49 is separated from the non-bevel end of the wedge-shaped clamping block 48, the two lose the tendency to hinder each other. As the rotor 45 further presses the pressing plate 42, the bevel end of the tooth 47 further abuts against the bevel end of the wedge-shaped clamping block 48. The pressing plate 42 cannot rotate under the limitation of the two side cover needles 43, and the teeth 47 can only drive the rotor 45 and the capsule driving wheel 11 connected to the rotor 45 to rotate at a micro-angle. The capsule driving wheel 11 drives the capsule in the puncture state to move slightly, and the side cover needles 43 and the main body needles 34 form a pull on the capsule shell to further damage the capsule shell. Because of the micro-angle rotation of the capsule driving wheel 11, the non-bevel end of the wedge-shaped clamping rod 49 connected to the rotor 45 passes over the non-bevel end of the wedge-shaped clamping block 48, thereby completing the destruction of the capsule shell.

[0069] Then, the force applied to press the button body 32 is released, and the button body 32 is reset under the reset of the spring 1 33, and the main body needle 34 is withdrawn from the first position from the side opening 35. After the rotor 45 loses the pressure of the button body 32, the pressing plate 42 presses against the rotor 45 and retreats into the inner channel under the reset of the spring 2 44, and the side cover needle 43 returns to its position. Because the non-beveled end of the wedge-shaped clamping rod 49 connected to the rotor 45 passes over the non-beveled end of the wedge-shaped clamping block 48 at this time, during the resetting process of the pressing plate 42, the beveled end of the wedge-shaped clamping block 48 presses against the beveled end of the wedge-shaped clamping rod 49, thereby causing the capsule driving wheel 11 connected to the wedge-shaped clamping rod 49 to rotate for the second time, and the capsule driving wheel 11 transports the punctured capsule to the bottom of the suction nozzle 2. After the pressing plate 42 presses against the capsule driving wheel 11 again, the non-beveled end of the wedge-shaped clamping rod and the non-beveled end of the wedge-shaped clamping block 48 resume the state of mutual restraint. Then the patient inhales, and the capsule rises and rotates under the flow channel 5 under the influence of the airflow (this principle is a mature technology, not the focus of the patent application), releasing the medicine powder. After the patient completes the inhalation, the capsule falls back into the capsule receiving groove 13 under the influence of gravity. At this time, the capsule that has not been punctured continues to be sent to the first position to wait.

[0070] Specifically, when the drug user presses the button body 32 to advance to the first depth, the main body needle 34 penetrates into the first position from the side opening 35 and presses against the shell of the capsule, and the capsule presses against the pressing plate 42 in the capsule receiving groove 13; when the drug user continues to press the button body 32 to advance to the second depth, the button body 32 presses against the rotor 45, and the rotor 45 is sent into the inner groove. The inclined ends of four of the eight teeth 47 press against the inclined ends of the wedge-shaped block 48, and the rotor 45 presses the pressing plate 42 to move along the side cover needle 43 in the contraction direction of the spring 2 44, and the side cover needle 43 penetrates out of the pressing plate 42, thereby completing the puncture of the two ends of the shell of the capsule located in the capsule receiving groove 13 with the main body needle 34; when the drug user continues to press the button body 32 to advance to the third depth, the wedge-shaped block 48 is pressed against the pressing plate 42. The non-beveled end of the rod 49 is separated from the non-beveled end of the wedge block 48, and the two lose the tendency to restrain each other. The capsule driving wheel 11 rotates at a slight angle, and the non-beveled end of the wedge rod 49 passes over the non-beveled end of the wedge block 48. The side cover needle 43 and the main body needle 34 form a pull on the capsule shell to further damage the capsule shell. After the drug user releases the force pressing the button body 32, under the reset of spring 1 33 and spring 2 44, the main body needle 34 and the side cover needle 43 are pulled out of the capsule shell, and the beveled end of the wedge block 48 abuts against the beveled end of the wedge rod 49, thereby causing the capsule driving wheel 11 connected to the wedge rod 49 to rotate for the second time, and the capsule driving wheel 11 transports the punctured capsule to the bottom of the suction nozzle 2, and the drug user can inhale it.

[0071] In one embodiment, the rotor 45 is hemispherical near the button body 32 , and a cavity for accommodating the center column 40 is provided at the rotor near the pressure plate 42 . Four wedge-shaped blocks 48 are arranged in an array with the center column 40 as the center circle.

[0072] The working principle and beneficial effects of the above technical solution are:

[0073] The rotor 45 is fed into the inner groove, and the center column 40 is inserted into the cavity, so that the precise movement of the rotor 45 is achieved.

[0074] In one embodiment, a flow channel 5 with a filter is disposed in the suction nozzle 2 , and an upper cover 6 for protecting the suction nozzle 2 is installed on the main frame 1 .

[0075] The working principle of the above technical solution is:

[0076] When the user inhales, the capsule will rise and rotate under the flow channel 5 under the influence of the airflow (this principle is a mature technology and is not the focus of patent application), releasing the powdered medicine, and the user completes the inhalation.

[0077] like Fig. 9 As shown, in one embodiment, the side cover needle 43 arranged opposite to the main body needle 34 includes:

[0078] The needle rod 51 is mounted on the side cover 41, and a limiting sleeve 50 is mounted on the pressing plate 42 and sleeved on the needle rod 51;

[0079] A needle 52, the needle 52 is mounted on the needle rod 51;

[0080] The action chamber is located in the needle rod 51 and is arranged close to the needle head 52. The micro screw 53 is rotatably installed in the action chamber and is connected to the needle head 52.

[0081] The screw sleeve 54 is sleeved on the micro screw 53. The micro spring 55 is sleeved on the micro screw 53 and is disposed between the inner wall of the action chamber and the screw sleeve 54.

[0082] The outer top ring 56 is sleeved on the needle rod 51, and the outer top ring 56 is adapted to the limit sleeve 50. A plurality of guide grooves 57 are circumferentially opened at the side end of the needle rod 51. The guide block is slidably connected in the guide groove 57 and is connected to the inner ring of the outer top ring 56 and the screw sleeve 54.

[0083] The working principle and beneficial effects of the above technical solution are:

[0084] When the patient presses the button body 32 to advance to the first depth, the main body needle 34 penetrates into the first position from the side opening 35 and abuts against the shell of the capsule, and the capsule abuts against the pressing plate 42 in the capsule receiving groove 13; when the patient continues to press the button body 32 to advance to the second depth, the button body 32 abuts against the rotor 45, and the rotor 45 is sent into the inner groove, and the inclined ends of four of the eight teeth 47 abut against the inclined ends of the wedge-shaped block 48, and the rotor 45 presses the pressing plate 42 along the side cover needle 43 to the spring The micro spring 55 moves in the contraction direction, and the needle 52 extends from the limiting sleeve 50, and the needle 52 punctures the shell of the capsule. As the penetration depth of the needle 52 increases, the limiting sleeve 50 drives the outer top ring 56, the guide block connected to the outer top ring 56, and the screw sleeve 54 connected to the guide block to slide along the guide groove 57, and the screw sleeve 54 moves in the contraction direction of the micro spring 55, thereby driving the micro screw 53 therein to rotate, and the micro screw 53 drives the needle 52 to rotate, so as to improve the puncture efficiency.

[0085] In one embodiment, the outer wall of the outer top ring 56 is closed in a direction close to the limiting sleeve 50 , and the small end of the outer top ring 56 is clamped in the inner ring of the limiting sleeve 50 .

[0086] In one embodiment, a rib 58 is provided at the side end of the needle 52 near the micro screw 53 , and the rib 58 is fixedly installed at the side end of the needle 52 in a spiral shape.

[0087] The working principle and beneficial effects of the above technical solution are:

[0088] When the needle 52 rotates, the rib 58 located thereon is driven to rotate, and the rib can play a role of expanding the hole to facilitate the needle 52 to be pulled out of the capsule shell.

[0089] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
