Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and specifically relates to an inhaler. Background Art

[0002] At present, the capsule-type powder inhaler used in clinical applications includes a shell, a nozzle, a capsule compartment and a puncture needle that can be inserted into the capsule compartment to puncture the capsule. When using, the patient needs to put the drug-containing capsule in the capsule compartment, and then adjust the cover covering the capsule compartment to a closed position so that the capsule compartment is only connected to the air inlet and the nozzle, and then press the button connected to the shell to drive the puncture needle to puncture the capsule, and then the reset structure allows the puncture needle to withdraw from the capsule, and the puncture needle punctures a hole in the capsule shell, and the drug in the capsule can leave the capsule shell through the hole on the capsule, and then the patient can inhale the drug through the nozzle.

[0003] When a patient uses the inhaler, he needs to put the capsule into the capsule chamber, close the capsule chamber, and then use a button to drive the puncture needle to pierce the capsule. The patient needs to perform multiple actions before inhaling the medicine, which is inconvenient to use. Summary of the invention

[0004] In order to achieve the capsule insertion and piercing of the capsule in one action, the present application provides an inhaler.

[0005] An inhaler comprises a shell provided with a suction nozzle, a receiving part provided with a capsule compartment and a puncture needle slidably connected to the receiving part, the puncture needle is also connected to the receiving part via an elastic part, and the puncture needle has a matching part and a puncturing end; a working part is provided inside the shell, the receiving part can enter and exit the shell along a first direction, the working part and / or the matching part are provided with a working surface, the working surface comprises a first sub-surface, and the first sub-surface gradually approaches a movement path of the capsule compartment along a direction of entering the shell in the first direction; when the receiving part enters the shell and the matching part passes through the working part, the matching part first abuts against the working part through the first sub-surface, and generates a displacement close to the capsule compartment under the guiding action of the first sub-surface, the puncturing end performs a puncturing action, and the elastic part undergoes elastic deformation; when the matching part leaves the working part, the matching part can generate a displacement away from the movement path of the capsule compartment under the elastic force of the elastic part, and the puncturing end performs a resetting action.

[0006] In the process of placing the containing member into the shell along the first direction, under the guiding action of the first sub-surface, the matching part is squeezed by the working part, thereby moving toward the capsule bin, so that the piercing end of the puncture needle pierces the capsule in the capsule bin, and then the containing member continues to move. In the process of the matching part leaving the working part, the matching part can be displaced away from the capsule bin under the elastic force of the elastic member, and the piercing end performs a resetting action, so that the puncture needle leaves the capsule, and the puncture needle leaves a hole in the capsule shell, and the medicine in the capsule leaves the capsule shell through the hole, and finally the containing member reaches the inhalation position, the suction nozzle is connected with the capsule bin, and the patient can inhale the medicine through the suction nozzle.

[0007] In one embodiment of the present application, the containing member is provided with at least two capsule compartments in the first direction, the shell is provided with a working part, each capsule compartment is respectively provided with a needle and an elastic member, and during the process of the containing member entering the shell, the mating parts of each needle pass through the working part in sequence.

[0008] When each capsule compartment enters the shell along the first direction, the matching parts of the puncture needles corresponding to each capsule compartment can pass through the working part in sequence, so that the capsules entering each capsule compartment are punctured in sequence according to the order of entering the shell, so as to achieve different medication purposes.

[0010] The first puncture needle and the second puncture needle can puncture the capsules in the first capsule chamber and the second capsule chamber at the same time, thereby preventing the capsules in the capsule chamber from being punctured prematurely and the drugs in the capsules from being released to the outside. On the other hand, the capsules in the two capsule chambers can be punctured and the drugs can be released at the same time, thereby meeting the needs of some patients to inhale mixed drug products at the same time.

[0011] In one embodiment of the present application, when the working surface is provided on the working part, along the direction of entering the shell along the first direction, the working surface of the working part has an extension direction of first gradually approaching the movement path of the capsule compartment and then gradually moving away from the movement path of the capsule compartment; when the working surface is provided on the matching part, along the direction of entering the shell along the first direction, the working surface of the matching part has an extension direction of first gradually moving away from the movement path of the capsule compartment and then gradually approaching the movement path of the capsule compartment.

[0012] When the working surface has an extension direction close to the capsule bin when entering the shell along the first direction, the containing member can smoothly enter the shell along the first direction; when the containing member leaves the shell along the first direction and moves in the opposite direction, there is a situation that the working part gets stuck with the needle; when the working surface is provided at the working part, the working surface has an extension direction first approaching the capsule bin and then away from the capsule bin when entering the shell along the first direction; when the working surface is provided at the matching part, the working surface has an extension direction first away from the capsule bin and then close to the capsule bin when entering the shell along the first direction, and the containing member can smoothly leave the shell along the first direction.

[0016] The nozzle branch can cover capsule compartments at different positions respectively, so that the medicine in the capsule compartment can reach the affected area as much as possible through the nozzle branch and the nozzle, avoiding the situation where the medicine is retained in the capsule compartment due to the patient's suction force, resulting in drug waste.

[0017] In one embodiment of the present application, a filter is provided in the nozzle branch.

[0018] In one embodiment of the present application, the containing member is provided with at least two capsule bins in a first direction, each of which is connected to an air inlet, and the capsule bin is connected to the outside through the air inlet.

In the process of placing the containing member into the shell along the first direction, under the guiding action of the first sub-surface, the matching part is squeezed by the working part, thereby moving into the capsule compartment, so that the piercing end of the puncture needle pierces the capsule in the capsule compartment, and then the containing member continues to move. In the process of the matching part leaving the working part, the matching part can be displaced away from the capsule compartment under the elastic force of the elastic member, and the piercing end performs a reset action, so that the puncture needle leaves the capsule, and the puncture needle leaves a hole in the capsule shell, and the medicine in the capsule leaves the capsule shell through the hole, and finally the containing member reaches the inhalation position, the suction nozzle is connected with the capsule compartment, and the patient can inhale the medicine through the suction nozzle.

[0044] See also Figure 1 , an inhaler, comprising a shell 101 provided with a nozzle 102, a containing part 201 provided with a capsule compartment 202 and a puncture needle 301 slidably connected to the containing part 201, the puncture needle 301 is also connected to the containing part 201 through an elastic part 304, the puncture needle 301 can enter and exit the capsule compartment 202 through a hole provided in the capsule compartment 202, and the puncture needle 301 has a matching portion 302 and a puncturing end 303.

[0045] The housing 101 is provided with a working portion 105, see Figures 1 to 3 , the containing member 201 can enter and exit the housing 101 along the first direction, Figure 1 The direction indicated by the arrow in is the direction when the containing member 201 enters the shell 101, the working part 105 and / or the matching part 302 are provided with a working surface 108, the working surface 108 includes a first sub-surface 109, and in the direction of entering the shell 101 along the first direction, the first sub-surface 109 gradually approaches the movement path of the capsule bin. In one embodiment of the present application, the working part 105 and the matching part 302 are both provided with a working surface 108, and the working part 105 and the matching part 302 are both provided with a first sub-surface 109, and the working surface 108 of the working part 105 is provided, and in the direction of entering the shell 101 along the first direction, the working surface 108 of the working part 105 has an extension direction of first gradually approaching the movement path of the capsule bin and then gradually moving away from the movement path of the capsule bin; the working surface 108 of the matching part 302 is provided, and in the direction of entering the shell 101 along the first direction, the working surface 108 of the matching part 302 has an extension direction of first gradually moving away from the movement path of the capsule bin and then gradually approaching the movement path of the capsule bin.

[0046] See also Figures 3 to 5 , containing part 201 along Figure 4The holding member 201 moves in the direction indicated by the middle arrow, and the holding member 201 begins to enter the shell 101 along the first direction. Due to the direction of entering the shell 101 along the first direction, the working surface 108 has an extension direction that gradually approaches the movement path of the capsule compartment, the working surface 108 of the working portion 105 has an extension direction that first gradually approaches the movement path of the capsule compartment, and the working surface 108 of the matching portion 302 has an extension direction that first gradually moves away from the movement path of the capsule compartment. Along the direction of entering the shell 101 in the first direction, the lateral distance between the first sub-surface 109 of the working portion 105 and the movement path of the capsule compartment gradually decreases. The "lateral" in the "lateral distance" described herein refers to the direction perpendicular to the first direction, and as the matching portion 302 moves, the lateral distance between the first sub-surface 109 of the working portion 105 and the movement path of the capsule compartment gradually decreases. The engaging portion 302 enters the shell 101 along the first direction, and the lateral distance between the first sub-surface 109 of the matching portion 302 abutting against the working portion 105 and the piercing end 303 gradually increases, while the working portion 105 is fixedly connected to the shell 101. When the matching portion 302 passes through the working portion 105 and slides relatively with the working portion 105, the matching portion 302 abuts against the working portion 105 through the first sub-surface 109, and the matching portion 302 is squeezed by the working portion 105 toward the motion path of the capsule compartment 202, resulting in a displacement close to the capsule compartment 202, so that the piercing end 303 of the puncture needle 301 pierces the capsule 204 in the capsule compartment 202 to perform the piercing action, and at the same time, the elastic member 304 undergoes elastic deformation, see Figure 5 The elastic member 304 can be a spring, elastic rubber, etc.

[0047] See also Figure 5 In the process that the containing member 201 continues to enter the shell 101 along the first direction, since the working surface 108 of the working portion 105 has an extension direction that first gradually approaches the movement path of the capsule compartment and then gradually moves away from the movement path of the capsule compartment; the working surface 108 of the matching portion 302 has an extension direction that first gradually moves away from the movement path of the capsule compartment and then gradually approaches the movement path of the capsule compartment, in the process that the matching portion 302 leaves the working portion 105, the working surface 108 of the working portion 105 and the capsule compartment The lateral distance of the movement path gradually increases, and the lateral distance between the working surface 108 of the matching part 302 abutting against the working part 105 and the piercing end 303 decreases. The matching part 302 can be displaced away from the movement path of the capsule compartment under the elastic force of the elastic member 304, and the piercing end 303 performs a reset action, so that the piercing end 303 of the puncture needle 301 can leave the capsule 204, and the puncture needle 301 leaves a hole in the shell of the capsule 204. The medicine in the capsule 204 can leave the capsule 204 through the hole in the capsule shell, and the containing member 201 reaches the inhalation position (see Figure 6 ), the suction nozzle 102 can be connected to the capsule compartment 202, and the air inlet 203 of the capsule compartment 202 is connected to the outside, see Figure 7The patient can inhale the medicine through the suction nozzle 102, so that the filling and puncturing process of the capsule 204 can be achieved by a movement of the containing member 201 entering the shell 101.

[0048] See also Figure 6 Due to the shape of the working surface 108 of the working part 105 and the working surface 108 of the matching part 302, the containing member 201 can move in the reverse direction. Similarly, when the containing member 201 moves in the first direction away from the shell 101, the piercing end 303 of the puncture needle 301 performs the piercing action and the reset action again, so that when the containing member 201 reciprocates in the first direction, the puncture needle 301 can repeatedly puncture the capsule 204, expand the hole on the capsule 204, and facilitate the medicine in the capsule 204 to enter the outside; of course, the containing member 201 can also leave the shell 101 in the first direction, see Figure 6 In the direction of the arrow in the figure, the capsule compartment 202 can be cleaned and filled.

[0049] See also Figure 2 In order to pierce the two ends of the capsule 204 along the length direction of the capsule compartment 202, the present application has two independent puncture needles 301 and two independent elastic members 304 on both sides of the capsule compartment movement path, respectively. The working portion 105 is two protrusions arranged on the shell 101. The movement path of the puncturing end 303 is parallel to the length direction of the capsule compartment 202. When the capsule is placed in the capsule compartment 202, the axial direction of the capsule is parallel to the length direction of the capsule compartment 202. See Figure 7 The puncture needle 301 can move along the axial direction of the capsule 204 to puncture the end of the capsule 204; the setting mode and setting position of the puncture needle 301 can also be an integrated puncture needle 301, the puncture needle 301 has two puncture ends 303 and a matching portion 302, the length direction of the capsule compartment 202 is perpendicular to the movement path of the puncture ends 303, the puncture ends 303 can move along the radial direction of the capsule 204, the two puncture ends 303 can puncture the side wall of the capsule 204, and the matching portion 302 is arranged above or above the containing member 201. The working part 105 can also be arranged as a protrusion above or below the shell 101, and the setting position of the working part 105 can be adaptively adjusted. Of course, there are other ways to set the position and setting method of the needle 301 and the working part 105. The length direction of the capsule chamber 202 can be perpendicular to the movement plane of the containing part, and can also be parallel to the movement plane of the containing part. The positional relationship between the length direction of the capsule chamber 202 and the movement path of the puncturing end 303 is adjusted according to the use requirements, which will not be repeated here.

[0050] Those skilled in the art to which the present application belongs can understand that the arrangement of the working surface 108 in the present application is not limited to the direction of entering the shell 101 along the first direction. The working surface 108 of the working portion 105 has an extension direction of gradually approaching the capsule compartment movement path and then gradually moving away from the capsule compartment movement path; the working surface 108 provided on the matching portion 302 has a direction of gradually moving away from the capsule compartment movement path and then gradually approaching the extension direction of the capsule compartment movement path. There are also other ways to enter the shell 101 along the first direction, see Figure 8 The working surface 108 of the matching portion 302 and the working surface 108 of the working portion 105 only have an extension direction gradually approaching the movement path of the capsule compartment, and both the matching portion 302 and the working portion 105 are provided with a first sub-surface 109; see Fig. 9 The working surface 108 is only provided on the working part 105, and the working surface 108 of the working part 105 has an extension direction gradually approaching the movement path of the capsule compartment, and the first sub-surface 109 is only provided on the working part 105; see Fig.10 , the working surface 108 is only arranged on the matching part 302, the working surface 108 of the matching part 302 has an extension direction gradually approaching the movement path of the capsule compartment, and the first sub-surface 109 is only arranged on the matching part 302; at the same time, due to the influence of the setting position of the working surface 108, the containing member 201 can only move along the first direction toward the direction of entering the shell, and the containing member 201 can pass through the shell 101, but cannot reciprocate along the first direction, see Fig. 9 , Fig.10 However, in the process of passing through the shell 101, the piercing end 303 can still perform the piercing action when the matching portion 302 passes through the working portion 105, and perform the resetting action under the action of the elastic member 304 after the matching portion 302 leaves the working portion 105.

[0051] Technicians in the technical field to which the present application belongs can understand that the friction force between the working part 105 and the matching part 302 in the present application is not limited to sliding friction, but can also be rolling friction, such as arranging a roller on the working part 105 and / or the matching part 302 so that when the matching part 302 moves relative to the working part 105, the roller located between the two can rotate. The specific implementation method will not be described here.

[0052] See also Figure 4In one embodiment of the present application, when the container 201 moves into the housing 101 along the first direction, a container movement plane is formed; the projection of the working surface in the container movement plane has an arc shape, so that the matching portion 302 can smoothly pass through the working portion 105, so that the puncturing end 303 can smoothly perform the puncturing action and the resetting action. The setting mode of the working surface 108 is not limited to the mode in which the projection of the working surface 108 in the container movement plane is an arc, and it can also be the direction of entering the housing 101 along the first direction, and the projection of the working surface 108 in the container movement plane is first a straight line, then an arc, and then a straight line, that is, the working surface 108 is composed of two planes and a curved surface; of course, the projection of the working surface 108 in the container movement plane can also not have an arc shape, and the working surface 108 can also be composed of two planes, and the projection on the container movement plane is two straight lines. The extension direction of the working surface 108 in the first direction will not be repeated here. Of course, the working surface 108 also has other implementation modes, which will not be repeated here.

[0053] See also Figure 1 , Figure 2 In one embodiment of the present application, a containing member 201 is provided with at least two capsule bins 202 in a first direction, and a shell 101 is provided with a working portion 105, wherein a working portion 105 here refers to two protrusions provided on the shell 101, and each capsule bin 202 is respectively provided with a puncture needle 301 and an elastic member 304. During the process of the containing member 201 entering the shell 101, the matching portion 302 of each puncture needle 301 passes through the working portion 105 in sequence. When each capsule bin 202 enters the shell 101 along the first direction, the matching portion 302 of the puncture needle 301 corresponding to each capsule bin 202 can pass through the working portion 105 in sequence, so that the capsules 204 entering each capsule bin 202 are punctured in sequence according to the order of entering the shell 101, so as to achieve different medication purposes.

[0054] Technicians in the technical field to which the present application belongs can understand that the number of capsule compartments 202 provided in the containing member 201 in the present application is not limited to one or two, but can also be three or even more, and during the process of the capsule compartment 202 entering the shell 101, the piercing end 303 can perform the piercing action and the resetting action.

[0055] Those skilled in the art of the present application can understand that the number of the working parts 105 in the present application is not limited to one, but can also be multiple, as illustrated below.

[0056] See also Fig.11In one embodiment of the present application, the capsule bin 202 includes a first capsule bin 202 and a second capsule bin 202, and the first capsule bin 202 and the second capsule bin 202 are arranged on the containing member 201 along the first direction; the thorn needle 301 includes a first thorn needle 307 and a second thorn needle 308, and the first thorn needle 307 and the second thorn needle 308 are slidably connected to the containing member 201, and the first thorn needle 307 and the second thorn needle 308 are also connected to the containing member 201 through an elastic member 304, respectively, and the first capsule bin 202 is correspondingly provided with a first thorn needle 307, and the second capsule bin 202 is correspondingly provided with a second thorn needle 308; the working part 105 includes a first working part 106 and a second working part 107, and the first working part 106 and the second working part 107 are two protrusions, and the first working part 106 and the second working part 107 are arranged on the shell 101 along the first direction; and the first working part 106 and the second working part 107 are arranged on the shell 101 along the first direction. The direction perpendicular to the second direction is the second direction, and the projection of the second needle 308 in the second direction is spaced from the projection of the first working part 106 in the second direction, so that in the process of the containing member 201 entering the shell 101, when the second needle 308 passes through the first working part 106, the matching portion 302 of the second needle 308 does not abut against the first working part 106, and the matching portion 302 of the second needle 308 does not generate a displacement close to the movement path of the second capsule bin, and the piercing end 303 of the second needle 308 does not perform the piercing action until the matching portion 302 of the second needle 308 contacts the second working part 107, and at the same time, the matching portion 302 of the first needle 307 contacts the first working part 106, and the piercing end 303 of the first needle 307 and the piercing end 303 of the second needle 308 can simultaneously perform the piercing action under the action of the working surface 108.

[0057] Ways to achieve the spacing between the projection of the second needle 308 in the second direction and the projection of the first working part 106 in the second direction include: the first capsule chamber 202 and the second capsule chamber 202 are spaced apart along the first direction and are located on the same straight line parallel to the first direction; when the matching portion 302 of the second needle 308 is in a natural state, the distance between the matching portion 302 of the second needle 308 and the movement path of the second capsule chamber is smaller than the distance between the first working part 106 and the movement path of the second capsule chamber, thereby achieving the spacing between the projection of the second needle 308 in the second direction and the projection of the first working part 106 in the second direction; ways to achieve the contact between the matching portion 302 of the second needle 308 and the second working part 107 and the contact between the matching portion 302 of the first needle 307 and the first working part 106 include: the first needle 307 and the second needle 308 are parallel to the second direction, and the distance between the first needle 307 and the second needle 308 in the first direction is equal to the distance between the first working part 106 and the second working part 107 in the first direction.
