Description

  The present invention is an aspirating dispenser in which a patient himself can destroy the capsule and suck the powder of the broken capsule, and the drug can be efficiently used until the patient sucks the drug. The present invention relates to a technique for making fine particles.

In the conventional suction-type prescription device, for example, a plurality of discharge paths are branched from the capsule storage chamber, and these discharge paths are connected to diffusion chambers arranged on the downstream side to diffuse the drug powder. There is a technique in which a swirl flow is generated in the diffusion chamber to further diffuse the powder supplied to the diffusion chamber to achieve atomization (see, for example, Patent Document 1).
Japanese Patent No. 3530004 (3rd page [0028])

  However, as a result of the test and research, the inventor of the present application has found that the conventional suction-type dosing device enters the patient's mouth in the swirling flow while taking the patient's constitution and physical condition into consideration. There are cases where it is better to suppress the swirling flow as much as possible, and the necessity has been recognized.

  In contrast, the inventor of the present application has come to recognize that the atomization of the drug powder is not achieved only by diffusion due to the swirl flow, but is also achieved by contact with the discharge path. That is, the inventor of the present application has found that the powder can be atomized more efficiently by using the discharge path provided in the prescription device.

  Therefore, the present inventor considered that the powder can be more efficiently atomized by extending the discharge path provided in the prescription device as much as possible, but such a suction-type prescription device can be used at any time. Since portability is important in this way, it is difficult to increase the size due to the extension of the discharge path.

The problem to be solved by the present invention is that when attempting to atomize by extending the discharge path, the portability is impaired due to the enlargement of the prescription device,
An object of the present invention is to provide an aspirating dosing device capable of efficiently finely pulverizing medicinal powder by contact with a discharge path without causing an increase in size of the medicating device.

The present invention includes a block body having a storage chamber for storing a capsule filled with medicinal powder, a body having a cylindrical portion loaded with the block body and provided with a breaking means for breaking the capsule in the storage chamber, A suction-type prescription device equipped with a mouthpiece for sucking capsule medicine powder that is fixed at the tip of the cylindrical portion of the body and broken in the storage chamber, and discharges the medicine powder to the outer peripheral surface of the block body And a plurality of straight grooves that form a straight path extending in the direction of the central axis of the cylindrical portion, and for discharging the drug powder inside the block body The main path for taking out the powder from the storage chamber, the branch part for branching the main path into a plurality of parts, and the powder from the branch part to each linear groove A plurality of branch channels, and the block body is A part of the discharge path for discharging the drug powder in the tip side part connected to the spice, which bypasses the drug powder passing through the straight groove with respect to the direction perpendicular to the central axis direction of the cylindrical part The detour has a first folding surface that collides with the powder from the straight groove and folds it back to the block body, and the powder that has been folded at the first folding surface collides with the detour. And a second folded surface that is folded back to the mouthpiece side and guided toward the suction port, and is configured as a space formed around the entire circumference of the block body inside the block body. it is characterized in that.

  In this case, it is preferable that the branch portion is a space having a larger inner diameter than the main channel and the branch channel.

According to the present invention, the medicine is good by providing a plurality of straight grooves that form a straight path that is a part of the discharge path for discharging the drug powder and extends in the central axis direction of the cylindrical portion. Diffusion is possible. That is, since the said linear groove is provided in the outer peripheral surface of a block body, compared with the case where it provides in the inside of a block body, it can ensure long time for a chemical | medical powder to contact with a discharge channel. That is, the chemical powder can be atomized efficiently by bringing the chemical powder into contact with the discharge path for an excessively long time.

  Furthermore, by providing the linear groove on the outer peripheral surface of the block body, the discharge path can be efficiently extended without changing the size of the block body. That is, even if the discharge path is extended by providing the linear groove on the outer peripheral surface of the block body, the suction-type dispenser does not increase in size.

  Therefore, according to the suction type dispensing device of the present invention, even if the discharge path length is extended, the powder can be efficiently pulverized without increasing the size of the dispensing device.

Further, in the present invention , a plurality of linear grooves are arranged around the block body at intervals, and the block body is a part of a discharge path for discharging the drug powder, from the storage chamber. a main passage for taking out the medicine powder, a branching unit for branching the main path to a plurality, by forming a plurality of shunt path for guiding the medicine powder to each of the linear groove from the branching portion, the shunt As the path becomes a part of the discharge path and the flow of the powder from the main path changes at the branch part, the atomization can be realized more efficiently by the contact of the powder at the branch part. it can.

  In this case, if the branching portion has a larger inner diameter than the main channel and the branch channel, dispersion at the branching portion is possible, and thus atomization can be realized more efficiently.

Furthermore, according to the present invention, inside the distal end side portion of the block body connected to the mouthpiece, a part of the discharge path for discharging the drug powder, the drug powder passing through the straight groove is transferred to the cylindrical portion. By forming a detour that guides the detour with respect to the direction orthogonal to the central axis direction, it is possible to secure a longer time for the powder to contact the discharge path by this detour. That is, the chemical powder can be atomized more efficiently by bringing the powder into contact with the discharge path for an extra portion of the detour.

  In addition, in this case, the detour makes the mouse collide with the first folded surface that collides with the powder from the straight groove and folds back toward the block body, and the powder that is folded back at the first folded surface. By having the second folded surface that is folded toward the side of the piece and led toward the suction port, there is no increase in size due to the extension of the discharge path. That is, even if the discharge path is extended by providing a new detour on the tip side portion of the block body, the suction-type dispensing device does not increase in size.

  Therefore, according to such a configuration, even if a detour is formed inside the tip side portion of the block body, the powder is more efficiently pulverized by contact with the discharge path without causing an increase in the size of the prescription device. Can be made.

Further, according to the present invention, the bypass passage, by configuring as internal all around space formed over around its axis of the block body, that are dispersed medicine powder, to promote atomization it can. Therefore, according to this configuration, the powder can be further dispersed and atomized.

  Inside the middle part 113, an opening 3 a is formed on the outer peripheral surface of the middle part 113, and two branch passages 3 are formed to guide the drug powder from the branch part 2 to the opening 3 a. Further, in this embodiment, as shown in the figure, the branch portion 2 is a branch chamber having a larger inner diameter than the main path 1 and the branch path 3.

  The middle part 113 further passes through the opening 3a formed on the outer peripheral surface of the middle part 113 and is a part of a discharge path for discharging the powder, and extends in the central axis direction of the cylindrical portion 121. Two straight grooves 113a for forming the existing straight path 4 are provided. The straight grooves 113a may be configured with the same diameter, and a structure that expands toward the mouthpiece side, a structure that contracts the diameter, or the like may be employed. Further, the straight path 4 can be configured as an internal passage of the middle part.

  The fourth part is a lower part indicated by reference numeral 114. As shown in FIG. 1, the lower part 114 is a part that connects the middle part 113 and the mouthpiece 130.

  The lower part 114 has an outer cylinder part 114a for fitting the front end side part of the middle part 113 therein, and the outer cylinder part 114a is connected to the middle part 113 by connecting with the middle part 113 so that a straight path is formed between the lower part 114a and the middle part 113. 4 is formed.

  Further, the lower part 114 is a part of the discharge path for discharging the powder between the middle part 113 and the shortest part of the powder passing through the straight groove 113a toward the suction port 131 of the mouthpiece 130. A detour 5 is formed that leads to a detour, i.e., a direction perpendicular to the axis O, i.e., a detour along a radial direction.

  The detour 5 forms the back surface of the lower part 114, forms a first folded surface 5a that collides with the powder from the straight groove 131a and folds it toward the block body 1, and a front end surface of the middle part 113. The first folded surface 5a has a second folded surface 5b that collides with the powder powder folded on the first folded surface 5a to be folded toward the mouthpiece 130 and led toward the suction port 131.

  Further, the first folded surface 5a of the present embodiment is formed of an annular recess formed on the back side of the lower part 114, and the ridge 114c surrounded by the folded surface 5a is sucked into the suction port 131 of the mouthpiece 130. A mouth introduction hole (hereinafter referred to as “introduction hole”) 6 is formed. The introduction hole 6 constitutes an inclined surface 6a whose diameter increases toward the upstream side.

  Further, the second folded surface 5b of the present embodiment is formed of an annular concave portion formed on the front end surface side of the middle part 113, and the raised portion 113b surrounded by the folded surface 5b is an inclined surface 6a of the introduction hole 6. It enters and serves as a guide to the introduction hole 6.

  That is, the detour 5 of the present embodiment is configured as a space formed around the entire circumference of the block body 1. According to such a configuration, it functions as a dispersion chamber for further atomizing the drug powder to further atomize, so that atomization can be promoted.

  The destruction means D according to the present embodiment is a punching means (hereinafter referred to as “perforation means D”) for making a hole in the capsule C disposed in the storage chamber Rc of the block body 1.

  The perforating means D is constructed integrally or separately from the body 120, and is supported by a cylindrical part D1 having an opening at the upper end thereof and an elastic member such as a spring S inside the cylindrical part D1 so as to be slidable. The push button D3 that is exposed through the cap D2 so as not to be pulled out from the opening at the upper end, and is fitted and held inside the upper portion of the push button D3, and the through-hole formed in the body 120 by pressing the push button D3 It consists of a pin D4 for perforating the capsule C by introducing the tip into the storage chamber Rc through 121a and the through hole n formed in the core part 111.

  The medication device 100 enables medication to a patient through the following operations.

  First, in order to arrange the capsule C in the storage chamber Rc, as shown in FIG. 3, it is only necessary to open the storage chamber Rc by rotating the lid 111a about the pivot P, thereby storing the capsule C. The chamber Rc can be easily loaded.

  Next, in order to suck the powder in the capsule C arranged in the storage chamber Rc with the prescription device 100, first, the push button D3 is pushed. Then, the pin D4 connected to the push button D3 is introduced into the storage chamber Rc against the elastic force of the spring S, and a hole is formed in the capsule C at the tip portion.

  Thereafter, when the hand is released from the push button D3, the pin D4 is returned to the position before being pushed in together with the push button D3 by the elastic force of the spring S. Then, the opening in the capsule C allows the powder in the capsule C to be introduced into the powder accumulation chamber R1 through the storage chamber Rc and the through hole n.

  After that, when the mouthpiece 130 is swallowed and inhaled, the outside air flows into the storage chamber Rc and the powder accumulation chamber R1 through the check valve 111b, and is mixed with the powder in the capsule C. It rises along the main road 1 toward the branch portion 2. Thus, if the main path 1 is formed so as to incline toward the branch portion 2, the powder can be efficiently atomized by contact with the main path 1.

  Next, in the branch part 2, the powder from the main path 1 is diverted from the branch part 2, so that the flow of the powder from the main path 1 changes in the branch part 2. By the contact with, the powder can be efficiently atomized.

  The medicinal powder divided from the branch part 2 ascends or descends along the respective diversion paths 3 toward the straight path 4. Thus, if the main path 1 is formed so as to incline toward the branch portion 2, the drug powder can be efficiently atomized even in contact with the branch path 3.

  Further, since the powder passing through the straight path 4 extends along the path along the axis O, the swirling flow of the powder can be suppressed. In addition, since the linear groove 131a is provided on the outer peripheral surface of the block body 1, it takes a longer time to contact the discharge path than when it is provided inside the block body 1. That is, the chemical powder can be atomized more efficiently by bringing the powder powder into contact with the discharge path for a longer time by the amount of the straight path 4 provided on the outer peripheral surface.

  In addition, the medicinal powder passing through the detour 5 extends so that the detour 5 detours with respect to the path along the radial direction, so that the time of contact with the discharge path becomes longer by the detour length. . That is, the chemical powder can be atomized more efficiently by bringing the chemical powder into contact with the discharge path for an extra length by the amount detoured by the detour 5.

  Thus, the mouthpiece 130 sucks the powder that has been atomized into the patient's mouth through the discharge path that takes the main path 1, the branch portion 2, the branch path 3, the straight path 4, the detour path 5, and the introduction hole 6 as a path. Inhaled through mouth 131.

  According to this embodiment, a straight groove 113a that is a part of the discharge path for discharging the powder and that forms the straight path 4 along the path along the axis O is provided on the outer peripheral surface of the block body 1. Therefore, compared with the case where it is provided inside the block body 1, it is possible to ensure a longer time for the medicinal powder to contact the discharge path. That is, the chemical powder can be efficiently atomized by bringing the powder powder into contact with the discharge path for an extra length corresponding to the amount of the linear groove 113a provided on the outer peripheral surface.

  Furthermore, by providing the linear groove 131a on the outer peripheral surface of the block body 110, the discharge path can be efficiently extended without changing the size of the block body 110. That is, even if the discharge path is extended by providing the linear groove 113a on the outer peripheral surface of the block body 110, the suction type prescription device does not increase in size.

  Therefore, according to the suction-type dispenser 100, the powder can be efficiently pulverized by contact with the discharge path without causing an increase in the size of the dispenser.

  Further, in this embodiment, a plurality of linear grooves 113a are arranged around the block body 110 at intervals, and inside the block body 110, a part of the discharge path for discharging the powder, A main path 1 for taking out the powder from the storage chamber Rc, a branch part 2 for branching the main path 1 into a plurality of branches, and a plurality of branch channels for guiding the powder from the branch part 2 to each linear groove 113a 3, the flow path 3 becomes a part of the discharge path, and the flow of the medicinal powder from the main path 1 changes in the bifurcated section 2. By contact, atomization can be realized more efficiently.

  Moreover, since the branch part 2 of this embodiment is a branch chamber that forms a space having a larger inner diameter than the main path 1 and the branch path 3, it is possible to disperse in the branch part 2, thereby further reducing atomization. Can be realized.

  Furthermore, according to the present embodiment, the inside of the tip side portion of the block body 110 connected to the mouthpiece 130 is part of the discharge path for discharging the powder, and the diameter of the powder that has passed through the straight groove 113a is reduced. By forming the detour circuit 5 that guides the detour with respect to the direction, it is possible to secure a longer time for the drug powder to contact the discharge path by this detour. That is, the chemical powder can be atomized more efficiently by bringing the powder into contact with the discharge path for an extra length corresponding to the detour in the detour 5.

  In addition, in this case, the detour 5 includes a first folded surface 5a that collides with the powder from the straight groove 113a and folds back toward the block body 110, and a powder that is folded back on the first folded surface 5a. And having the second folded surface 5b led to the suction port 131 and collapsing toward the mouthpiece 130, there is no increase in size due to the extension of the discharge path. That is, the prescription device 100 does not increase in size even if the discharge path is extended by providing the new detour 5 at the distal end portion of the block body 110.

  Therefore, according to such a configuration, even if the bypass 5 is formed inside the distal end portion of the block body 110, the drug powder can be more efficiently brought into contact with the discharge path without causing an increase in the size of the prescription device. Can be micronized.

  In addition, according to the present embodiment, the detour 5 is configured as a dispersion chamber that is a space formed around the entire circumference of the block body 1 around the axis O, thereby dispersing the drug powder, Atomization can be promoted. Therefore, according to this configuration, the powder can be further dispersed and atomized.

These are exploded views of the same form. In addition, the same part as another form has the same code | symbol, and abbreviate | omits the description.

  Also in this embodiment, the block body 110 is composed of four parts, but the core part 111 has a storage chamber Rc in which the capsule C can be stored in a vertically oriented state, and a drilling pin D4 is also included. It shall be a single one.

  That is, this embodiment is different from the other embodiments in that the punching means D is opened and closed by rotating the punching means D with respect to the core part 111 with the pivot P as a base point.

  For this reason, according to this invention, it can apply also to the prescription device from which the loading method of such a capsule differs.

  The above is a preferred embodiment of the present invention, but various modifications can be made within the scope of the claims. For example, the structures employed in each form can be used in appropriate combination.

  Any medication device can be used for various medication devices as long as portability is given to the portability in which the powder filled in the capsule is taken out by destruction and the patient performs suction.
