Description

  The present invention relates to a drug inhalation device. Specifically, the inhalation device of the present invention is for orally administering, for example, a powdered medicine to a patient. The patient can inhale the medicament through the inhalation device of the present invention.

  2. Description of the Related Art Conventionally, there are known devices for causing a patient to inhale, for example, a drug that suppresses inflammation of the airways or promotes bronchial dilatation (Patent Document 1, Patent Document 2, etc.) Such an inhalation device uses a patient's own inspiratory force to administer a powdered drug directly to the respiratory tract or lungs, which are affected by inflammation. It has the advantage that it can be applied automatically, the side effects can be suppressed, and the effect can be expressed quickly.

  As shown in Patent Document 1 and Patent Document 2, in one of the typical inhalation devices, a band-shaped pharmaceutical carrier enclosing a medicine is stored in a spiral shape. A band-shaped pharmaceutical carrier is constructed by laminating the inner surfaces of a long base sheet and a lid sheet, and a plurality of blisters forming a space for encapsulating a drug are formed on the base sheet at intervals in the longitudinal direction. Has been. The base sheet is provided with blisters corresponding to the required number of times of drug administration, and each blister is loaded with a desired drug in an amount suitable for one administration. At the time of drug administration, the lid sheet is peeled off from the base sheet so that an appropriate amount of drug is exposed.

  One of the typical inhalation devices includes a spool for winding up the base sheet and a spool for winding up the cover sheet. By rotating these spools in conjunction with each other, Apply tension to the lid sheet. When tensions in opposite directions are applied to the base sheet and the lid sheet, these sheets are peeled off at the separation point to expose the drug enclosed in the blister. The inhalation device is provided with an inhalation port for inhaling a drug in the vicinity of the separation point of both sheets. This allows patients to inhale medication through the device's inlet.

Special table 2004-512147 gazette JP-T-2005-506164

  As described above, a pharmaceutical carrier is provided with blisters for the number of administrations of a drug necessary for treatment of a disease. Each blister contains an appropriate amount of medicine to be taken at once. For this reason, the patient can take an appropriate amount of the drug without excess or deficiency by inhaling the drug in each blister at an appropriate time and dividing it into an appropriate number of times. However, in the general inhalation device described above, the patient manually rotates the spool that winds up the base sheet or the lid sheet, opens the blister, and inhales the medicine in the blister. For this reason, for example, when the patient excessively rotates the spool too much, there is a risk that two or more blisters may be opened at a time. In this case, there has been a problem that the patient inhales an amount of the drug that exceeds the appropriate amount to be taken at one time, and the patient cannot take the drug in the necessary number of times. On the other hand, if the patient's force to rotate the spool is weak, the blister may not be completely opened, but may be partially opened. In such a case, even if the patient inhales, the drug may remain in the blister, causing a problem that an appropriate amount of drug cannot be taken.

  Therefore, at present, there is a need for an inhalation device that allows a patient to open blisters one by one and easily inhales an appropriate amount of medicine in appropriate numbers.

  In addition, many conventional inhalation devices are disposable, and there are devices that need to be disposed of after the use of one pharmaceutical carrier. Even if the medicine carrier can be replaced, after opening all the blisters contained in one medicine carrier, the housing of the inhalation device is disassembled and the It was necessary to take out the medicinal carrier and wind it up again with a new medicinal carrier. As described above, in the conventional inhalation device, even if the medicine carrier can be exchanged, the work for exchanging it has been complicated.

  For this reason, there is now a need for an inhalation device that can easily replace a used pharmaceutical carrier.

Therefore, as a result of intensive studies on the means for solving the problems of the conventional invention, the inventor of the present invention forms perforations on a blister card having a plurality of blisters encapsulating a drug, and this perforation proceeds. In conjunction with this, we found that it is easier for the user to open the blisters one by one by driving a stop mechanism (stop lever) that stops the progress of the blister card. The inventor has conceived that the problems of the prior art can be solved based on the above knowledge, and has completed the present invention.
More specifically, the present invention has the following configuration.

The first aspect of the present invention relates to an inhalation device.
The inhalation device 200 of the present invention is an apparatus that arranges a medicine sealed in a blister card 100 at a position where a patient can inhale.
In one embodiment of the inhalation device 200 of the present invention, the blister card 100 includes a base sheet 110, a lid sheet 120, and a card base 130.
The base sheet 110 has a plurality of blisters 111 loaded with a medicine.
The lid sheet 120 is bonded to the surface of the base sheet 110 where the blister 111 is opened, and encloses the medicine in the blister 111.
The card base 130 is overlaid on the surface of the base sheet 110 on which the blister 111 is projected. The card base 130 has a plurality of openings 131 and perforations 132. Each of the plurality of blisters 111 is fitted into the plurality of openings 131 when the card base 130 and the base sheet 110 overlap. The perforation 132 is formed by a plurality of holes regularly arranged along the longitudinal direction of the card base 130.
The inhalation device 200 of the present invention includes a transport lane 210, a pinch mechanism 220, an air piece 230, and a stop lever 240.
The transport lane 210 forms a transport path for the blister card 100.
The pinch mechanism 220 peels the lid sheet 120 from the base sheet 110 of the blister card 100 on the conveyance path to expose the medicine in the blister 111.
The air piece 230 is arranged in the transport path and has an inlet 231 through which the medicine in the blister 111 passes.
The stop lever 240 stops the transfer of the blister card 100 when the blister 111 of the blister card 100 is at a position facing the suction port 231 of the air piece 230. Here, the stop lever 240 has a locking claw 241 inserted into a hole forming the perforation 132 of the blister card 100.

  As described above, the inhalation device 200 of the present invention includes the stop lever 240 that stops the transfer of the blister card 100, and the stop lever 240 is inserted into the perforation 132 formed in the blister card 100. have. As described above, since the latching claw 241 of the stop lever 240 is inserted into the perforation 132 of the blister card 100, the stop lever 240 is interlocked with the progress of the blister card 100, and an appropriate It is possible to stop the progress of the blister card 100 at the position. Here, “appropriate position” for stopping the progression of the blister card 100 means that only one blister 111 is opened, and one opened blister 111 faces the inlet 231 of the air piece 230. Position. Thus, by stopping the blister card 100 in conjunction with the progress of the blister card 100, the patient can surely open the blisters one by one.

In the suction device 200 of the present invention, the pinch mechanism 220 preferably includes a drive pinch roller 221, a driven pinch roller 222, and a drive gear 223 fitted on the rotation shaft of the drive pinch roller 221. . In this case, the pinch mechanism 220 is configured such that the driving pinch roller 221 rotates while sandwiching the lid sheet 120 of the blister card 100 between the driven pinch roller 222 and peeling the lid sheet 120 from the base sheet 110. The card 100 is advanced along the transport path.
In the inhalation device 200 of the present invention, it is preferable that the stop lever 240 further includes a gear stop pawl 242 inserted into the drive gear 223 or the gear teeth interlocking therewith. In this case, when the blister card 100 moves along the transport path while the locking claw 241 is inserted into the perforation 132 of the blister card 100, the entire stop lever 240 slides, The stop pawl 242 is inserted into the winding gear 250 or the gear teeth interlocked therewith, thereby stopping the rotation of the drive gear 223 or the gear interlocked therewith.

  As described above, in the present invention, the blister card 100 has the perforation 132, and the stop lever 240 of the inhalation device 200 has the locking claw 241 inserted into the perforation 132. Accordingly, the stop lever 240 slides. When the stop lever 240 is slid, the gear stop pawl 242 provided on the stop lever 240 is engaged with a gear for driving the pinch mechanism 220 that advances the blister card 100. Thus, when the gear stop pawl 242 is engaged with the gear that drives the pinch mechanism 220, the rotation of the gear is stopped, and as a result, the blister card 100 is also stopped. In this manner, the stop lever 240 stops driving the pinch mechanism 220 in conjunction with the progress of the blister card 100, so that the patient can easily open the blisters one by one. Further, in the present invention, the substantially straight blister card 100 can be used by being inserted into the inhalation device 200, and the used blister card 100 is directly discharged from the discharge port of the inhalation device 200. The replenishment and replacement of the blister card 100 can be performed very easily.

  The inhalation device 200 of the present invention preferably further includes a winding gear 250 and an interlocking gear 251 that shares the rotation axis with the winding gear 250 and meshes with the driving gear 223 to interlock. In this case, the gear stop pawl 242 of the stop lever 240 is preferably inserted into the teeth of the winding gear 250.

  As described above, the winding gear 250 and the interlocking gear 251 are provided separately from the driving gear 223 attached to the driving pinch roller 221, and the gear stopping claw 242 is engaged with the winding gear 250, thereby The degree of freedom in designing the entire device 200 is increased.

  The inhalation device of the present invention preferably further includes a winding lever 260 having a linear rack gear 261 that meshes with the winding gear 250.

  As described above, the winding device 260 is provided on the suction device 200, and the rack gear 261 that meshes with the winding gear 250 is formed on the winding lever 260, so that the blister card 100 can be advanced only by sliding the winding lever 260. This makes it easier for the patient to open the blister.

In the inhalation device 200 of the present invention, the transport lane 210 is preferably linear.
In this case, the transport lane 210 forms a transport lane 211 on the introduction side that forms a transport path upstream of the suction port 231 of the air piece 230 and a transport path that is downstream of the suction port 231 of the air piece 230 in the transport direction. And a discharge-side transport lane 212.

  As the above configuration, the blister card 100 can be opened one by one more reliably because the transfer lane 210 of the blister card 100 is linear. That is, in the conventional inhalation device, the belt-shaped drug carrier is wound and stored in a spiral shape, and the conveyance path of the drug carrier has an arc shape. Therefore, it is difficult to control the opening operation of the blisters, and a plurality of blisters are opened simultaneously. It may be difficult to open the blister completely. In this regard, in the present invention, the structure of the inhalation device is renewed, and a linear transport lane 210 is provided so that the blister card 100 travels along a linear transport path. As a result, in the inhalation device of the present invention, the blister card 100 is conveyed in a linearly extending state in the vicinity of the opening and closing points of the blister, so that the blisters of the blister card 100 can be reliably opened one by one. ing.

  In another embodiment of the inhalation device of the present invention, the blister card 100 includes a base sheet 110 having a plurality of blisters 111 loaded with a medicine, and a lid sheet 120 that is bonded to the base sheet 110 and encloses the medicine in the blister 111. The base sheet 110 and / or the cover sheet 120 have perforations 132 formed by a plurality of holes regularly arranged along the longitudinal direction thereof.

  As described above, in the inhalation device of the present invention, the card base 130 described above can be omitted, and instead, the base sheet 110 and / or the cover sheet 120 in which the perforations 132 are formed can be handled. .

The second aspect of the present invention relates to a blister card having a blister containing a medicine.
The blister card 100 of the present invention includes a base sheet 110 having a plurality of blisters 111 loaded with a medicine, and a lid sheet 120 that is bonded to the base sheet 110 and encloses the medicine in the blister 111. Here, both or any one of the base sheet 110 and the lid sheet 120 has a perforation 132 formed by a plurality of holes regularly arranged along the longitudinal direction thereof.

  The blister card 100 having the above configuration can easily open the blisters one by one if the inhalation device according to the first aspect of the present invention is used.

  According to the present invention, it is possible to provide an inhalation device and a blister card in which a patient can surely open blisters one by one and can easily inhale an appropriate amount of medicine divided into appropriate times. it can.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments described below, but includes those appropriately modified by those skilled in the art from the following embodiments.

(1. Blister card: first embodiment)
FIG. 1 is a view for explaining the structure of a blister card used in the present invention. FIG. 1 shows a first embodiment of a blister card. 1A is an exploded perspective view of the blister card, FIG. 1B is a perspective view of the assembled blister card as viewed from the back side, and FIG. 1C shows the assembled blister card. It is the perspective view seen from the front side. As shown in FIG. 1A, in the present embodiment, the blister card 100 includes a base sheet 110, a lid sheet 120, and a card base 130.

  The base sheet 110 is a long sheet member formed in a belt shape. The base sheet 110 has a plurality of blisters 111 regularly arranged along the longitudinal direction. The blister 111 is formed by a recess provided in the base sheet 110. For this reason, the surface side of the base sheet 110 is a surface where the blister 111 is opened, and the back surface side of the base sheet 110 is a surface where the blister 111 protrudes. The number of blisters 111 can be adjusted as appropriate. For example, the number of blisters 111 may be 3 to 30, 7 to 21, or 10 to 14. Each of the plurality of blisters 111 is basically loaded with the medicine 112.

  The drug loaded in the blister 111 of the base sheet 110 is preferably in the form of powder. However, the blister 111 can contain a liquid medicine, a solid tablet or the like. In particular, the inhalation device of the present invention can be suitably used for orally administering a drug for treating respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), bronchitis, or chest infection to a patient. A known drug may be used. For example, drugs loaded into blister 111 include analgesics such as codeine, dihydromorphine, ergotamine, fentanyl or morphine; angina drugs such as diltiazem, anti-allergic drugs such as cromoglycic acid compounds and ketotifen or nedocromil; cephalosporin Or anti-infectives such as penicillins; antihistamines such as metapyrylene; anti-inflammatory agents such as beclomethasone, fluticasone, or flunisolide; antitussives such as noscapine; One type or a plurality of types can be selected.

  The lid sheet 120 is a long sheet member formed in a band shape that is bonded to the surface of the base sheet 110 where the blister 111 is opened. The base sheet 110 and the lid sheet 120 are joined in a manner that can be peeled from each other. Thus, the blister 111 of the base sheet 110 is sealed by bonding the base sheet 110 and the lid sheet 120 together. As shown in FIG. 1A and the like, the lid sheet 120 is longer than the base sheet 110, and the distal end portion 121 on one side in the longitudinal direction preferably extends from the base sheet 110. Thus, by extending the front end portion 121 of the lid sheet 120 from the base sheet 110, the lid sheet 120 can be easily peeled off from the base sheet 110. It is preferable that the front-end | tip part 121 of the lid | cover sheet 120 is extended about 5 mm-20 mm, for example. In the blister card 100, the side where the cover sheet 120 extends from the base sheet 110 is the leading side when introduced into the inhalation device 200. The base sheet 110 and the lid sheet 120 are each preferably formed of a plastic material, an aluminum material, or a laminate thereof. For joining the base sheet 110 and the lid sheet 120, a known adhesive or a joining method such as heat sealing can be employed.

  The card base 130 is a long plate-like member that serves as a base for supporting the base sheet 110 and the lid sheet 120. The card base 130 is preferably formed of, for example, hard plastic or metal. The card base 130 is preferably formed thicker than the combined thickness of the base sheet 110 and the lid sheet 120. For example, the thickness of the card base 130 is about 0.5 mm to 5 mm, or about 1 mm to 3 mm. Is preferred. As shown in FIG. 1A and the like, the card base 130 has a plurality of openings 131 formed at regular intervals along the longitudinal direction at the center in the width direction. As shown in FIG. 1B, the opening 131 of the card base 130 is fitted with a protrusion formed by the blister 111 of the base sheet 110. That is, the shape and arrangement of each opening 131 of the card base 130 correspond to the arrangement and shape of the blister 111. In this way, the card base 130 is overlaid on the surface of the base sheet 110 on which the blister 111 protrudes.

  Further, the card base 130 is provided with a plurality of hole portions at regular intervals along the longitudinal direction at positions closer to the outer side in the width direction than the row of the opening portions 131, thereby forming perforations 132. Each hole forming the perforation 132 has a smaller opening area than the opening 131. The intervals at which the plurality of holes forming the perforation 132 are provided may be, for example, those corresponding to the intervals between the plurality of openings 131. The intervals between the plurality of holes and the intervals between the plurality of openings 131 are preferably the same or an integer multiple. The perforation 132 may be provided on one side of the card base 130, but may be provided on both sides of the card base 130.

  Further, the card base 130 has a notch 133 formed on one side (leading side) in the longitudinal direction. Since the notch 133 is formed at the tip of the card base 130 as described above, when the base sheet 110, the cover sheet 120, and the card base 130 are overlapped as shown in FIG. The leading end portion 121 of the sheet 120 protrudes at the notch 133 of the card base 130. Thus, it is preferable that the front end portion 121 of the lid sheet 120 protrudes from the notch 133 of the card base 130.

(2. Inhalation device)
FIG. 2 is a perspective view showing the basic structure of the inhalation device of the present invention. In FIG. 2, the internal mechanism of the housing of the inhalation device 200 is schematically shown. Although the illustration of the case of the inhalation device 200 is omitted, the shape of the case may be any shape that can accommodate the internal mechanism shown in FIG. For example, the shape of the housing may be a substantially rectangular shape.

As shown in FIG. 2, the inhalation device 200 basically includes a conveyance lane 210, a pinch mechanism 220, an air piece 230, a stop lever 240, a winding gear 250, a winding lever 260, and a lid sheet folding. And a piece 270. The transport lane 210 is used to place the blister card 100 and forms a transport path for the blister card 100. The pinch mechanism 220 pulls the cover sheet 120 of the blister card 100 to separate the cover sheet 120 from the base sheet 110 and to move the blister card 100 along the transport path of the transport lane 210. The air piece 230 has an inlet through which the medicine sealed in the blister 111 of the blister card 100 passes, and the patient can inhale the medicine through the air piece 230. The stop lever 240 stops the driving of the pinch mechanism 220 according to the progress of the blister card 100, and as a result, stops the progress of the blister card 100. The winding gear 250 interlocks the pinch mechanism 220 and the winding lever 260. The winding lever 260 is interlocked with the pinch mechanism 220, and the pinch mechanism 220 is driven by pushing the winding lever 260. The lid sheet bent piece 270 bends the leading end portion of the lid sheet 120 and introduces the leading end portion into the pinch mechanism 220.
Hereinafter, the structure of each part will be described in detail along with the operation of the inhalation device 200.

  FIG. 3 shows an initial state in which the blister card 100 is set in the inhalation device 200. As shown in FIG. 3, the blister card 100 is placed on the transport lane 210 of the inhalation device 200. For example, if a lateral hole for inserting the blister card 100 is provided in the housing (not shown) of the inhalation device 200, the blister card 100 inserted into the lateral hole is set on the transport lane 210. Good. In the present embodiment, the inhalation device 200 is designed on the assumption that the lid sheet 120 of the blister card 100 is placed in contact with the transport lane 210. For this reason, the base sheet 110 and the lid sheet 120, which are sheet-like members, are sandwiched between the transport lane 210 and the card base 130. Further, as shown in FIG. 3, the blister card 100 has the card base 130 on the side where the notch 133 is formed, that is, the side where the front end portion 121 of the lid sheet 120 extends from the base sheet 110, It is set on the transport lane 210.

  Further, as shown in FIG. 3, in the present embodiment, the transportation lane 210 forms a linear transportation path. For this reason, the blister card 100 travels linearly along the transport lane 210. The conveyance lane 210 includes an introduction-side conveyance lane 211 that forms a conveyance path upstream of the air piece 230 in the conveyance direction, and a discharge-side conveyance lane 211 that forms a conveyance path downstream of the air piece 230 in the conveyance direction. It is divided into a transport lane 212. Both the introduction-side conveyance lane 211 and the discharge-side conveyance lane 212 form a linear conveyance path, and the blister card 100 travels from the introduction-side conveyance lane 211 toward the discharge-side conveyance lane 212. . Thus, since the conveyance lane 210 is formed in a flat linear shape, the blister card 100 is also conveyed in a state of extending flat. Therefore, even if the base sheet 110 and the cover sheet 120 forming the blister card 100 are relatively soft sheet-like members, the base sheet 110 and the cover sheet 120 are straightly extended by being placed on the transport lane 210. It becomes easy to take out the medicine in the blister 111 by peeling off 120. In addition, both the introduction side 211 and the discharge side 212 of the transfer lane 210 are linear, and the base sheet 110 and the cover sheet 120 forming the blister card 100 are continued from the introduction to the suction device 200 until the discharge. In other words, it is sandwiched between the rigid transport lane 210 and the card base 130 and is in a flat state. For this reason, the inhalation device 200 of the present invention has a structure that can be easily peeled off from the base sheet 110 by pulling the lid sheet 120.

  FIG. 4A shows a state in which the blister card 100 is pushed further into the back from the state shown in FIG. FIG. 4B is an enlarged side view of the inhalation device 200 shown in FIG. As shown in FIGS. 4A and 4B, when the blister card 100 is pushed in, the leading end portion of the blister card 100 reaches the portion where the pinch mechanism 220 for peeling the lid sheet 120 from the base sheet 110 is located. . More specifically, a central opening 213 is formed near the center of the transport lane 210, and the pinch mechanism 220 and the air piece 230 are disposed in the central opening 213. The pinch mechanism 220 is located below the conveyance path of the blister card 100, that is, on the side facing the lid sheet 120, and has a configuration for pulling the lid sheet 120 downward.

  4A and 4B, a lid sheet bent piece 270 is provided above the conveyance path of the pinch mechanism 220 and the blister card 100. The lid sheet bent piece 270 has a support shaft 272 on one side of the piece main body 271 and a bent claw 273 protruding downward on the other side of the piece main body 271. The support shaft 272 is rotatably fixed to a fixing member (not shown) such as a housing, and the lid sheet bent piece 270 is rotated about the support shaft 272 as a rotation shaft. Further, the lid sheet bent piece 270 is biased downward by a spring member or the like (not shown). For this reason, when the blister card 100 is pushed in and the leading portion thereof reaches below the folding claw 273 of the lid sheet folding piece 270, the leading end portion of the lid sheet 120 located at the notch 133 of the card base 130 121 is pushed and bent downward by the bent claws 273. That is, as described above, since the blister card 100 has the tip portion 121 of the lid sheet 120 extending beyond the base sheet 110, only the tip portion 121 of the extended lid sheet 120 is lowered by the bent claws 273. It can be bent toward Thus, the front end portion 121 of the lid sheet 120 is introduced into the pinch mechanism 220 by being bent downward.

  FIG. 5 is a schematic diagram in which the pinch mechanism 220 and a mechanism interlocked therewith are extracted and drawn. As shown in FIG. 5, the pinch mechanism 220 includes a drive pinch roller 221, a driven pinch roller 222, and a drive gear 223. A drive gear 223 is fitted on the rotation shaft 221a of the drive pinch roller 221, and when the drive gear 223 rotates, the drive pinch roller 221 also rotates. The driven pinch roller 222 pulls the lid sheet 120 of the blister card 100 with the drive pinch roller 221. In the present embodiment, the driven pinch rollers 222 are provided one by one on the left and right side walls of the air piece 230. For this reason, in this embodiment, the pinch mechanism 220 and the air piece 230 are arrange | positioned in the adjacent position.

  In the present embodiment, a winding gear 250 and a winding lever 260 are provided as a mechanism for rotating the drive gear 223. An interlocking gear 251 is fitted on the rotating shaft 250 a of the winding gear 250, and the interlocking gear 251 meshes with a driving gear 223 for rotating the driving pinch roller 221. The winding lever 260 has a plate-shaped or rod-shaped lever main body 261 formed with a linear rack gear 262, and the rack gear 262 meshes with the winding gear 250. More specifically, the rotation shaft 250a of the winding gear 250 and the interlocking gear 251 and the rotation shaft 221a of the drive pinch roller 221 and the drive gear 223 are attached to the support block 224. That is, the rotation shaft 250 a of the winding gear 250 and the rotation shaft 221 a of the drive pinch roller 221 are connected by the support block 224.

  Next, the operation of the pinch mechanism 220 will be described. The pinch mechanism 220 transitions from the state shown in FIG. 5A to the state shown in FIG. That is, as shown in FIGS. 5A and 5B, when the winding lever 260 is pushed in the direction of the arrow shown in FIG. 5B, the winding gear meshed with the rack gear 262 of the winding lever 260. 250 rotates. When the winding gear 250 rotates, the support block 224 to which the rotating shaft 255a of the winding gear 250 is attached is rotated by the rotational torque. As the support block 224 rotates, the rotation shaft 221a of the drive pinch roller 221 is lifted. Then, the outer peripheral surface of the drive pinch roller 221 comes into contact with the outer peripheral surface of the driven pinch roller 222 attached to the air piece 230. Although not shown in FIG. 5, when the drive pinch roller 221 and the driven pinch roller 222 come into contact with each other, the lid sheet 120 of the blister card 100 is sandwiched between these rollers. Then, the winding lever 260 is further pushed in with the cover sheet 120 being sandwiched between the drive pinch roller 221 and the driven pinch roller 222. When the winding lever 260 is pushed, the winding gear 250 rotates and the interlocking gear 251 that shares the rotating shaft 250a with the winding gear 250 also rotates. Further, when the interlocking gear 251 rotates, the driving gear 223 rotates and the driving pinch roller 221 that shares the driving gear 223 and the rotating shaft 221a rotates. Thus, when the drive pinch roller 221 rotates, the cover sheet 120 sandwiched between the drive pinch roller 221 and the driven pinch roller 222 is pulled downward. Further, when the lid sheet 120 is pulled by the pinch mechanism 220, the lid sheet 120 is peeled from the base sheet 110. When the lid sheet 120 is peeled from the base sheet 110, the medicine in the blister 111 is exposed. Further, when the lid sheet 120 is pulled by the pinch mechanism 220, the entire blister card 100 advances along the transport path.

  Further, a suction port 231 of the air piece 230 is provided at a position where the medicine in the blister 111 is exposed. The suction port 231 of the air piece 230 is a through-hole and communicates with the outside of the housing of the suction device 200. For this reason, the patient can inhale the medicine through the inlet 231 of the air piece 230 by holding the air piece 230 and inhaling.

  FIG. 6A shows a state in which the blister card 100 has further advanced from the state shown in FIG. FIG. 6B shows an extracted gear mechanism. As shown in FIGS. 6A and 6B, when the blister card 100 is advanced, the base sheet 110 and the card base 130 are transported from the introduction-side transport lane 211 to the discharge-side transport along a straight transport path. Proceed to lane 212. On the other hand, the lid sheet 120 is pulled downward by the pinch mechanism 220 as the blister card 100 advances.

  Next, a mechanism for stopping the progress of the blister card 100 at an appropriate position will be described with reference to FIG. As shown in FIG. 7, the inhalation device 200 of the present invention includes a stop lever 240 as a mechanism for stopping the progress of the blister card 100 at an appropriate position. The stop lever 240 is located above the transport path of the blister card 100. The stop lever 240 transitions from the state shown in FIG. 7A to the state shown in FIG. 7C through the state shown in FIG. 7B, and stops the blister card 100 from proceeding.

As shown in FIGS. 7 and 2, the stop lever 240 includes a lever main body 243, a locking claw 241 formed on a part of the lever main body 243, and a gear stop claw formed on a part of the lever main body 243. 242 and a slide opening 244.
The locking claw 241 of the stop lever 240 protrudes downward, and the tip of the locking claw 241 can be inserted into the hole of the perforation 132 of the blister card 100. As shown in FIG. 7A, in the initial state where the blister card 100 is set in the inhalation device 200, the locking claw 241 of the stop lever 240 is not inserted into the perforation 132 of the blister card 100. In other words, it is in a state of running over the blister card 100. Thereafter, as shown in FIG. 7B, when the blister card 100 is pushed in and the hole of the perforation 132 reaches the lower side of the locking claw 241, the locking claw 241 falls and the perforation 132 is inserted into the hole.

  When the locking claw 241 is inserted into the perforation 132 of the blister card 100, the stop lever 240 slides with the blister card 100 so as to follow the progress of the blister card 100. That is, as shown in FIGS. 7 and 2, the stop lever 240 is formed with a slide opening 244 in the lever body 243. Further, a protrusion 214 provided on the transport lane 210 is inserted into the slide opening 244 of the stop lever 240 (see FIG. 2). The slide opening 244 of the stop lever 240 is provided with a certain amount of play (space) so that the stop lever 240 can slide back and forth, and a protrusion 214 is inserted therein. Thus, the stop lever 240 is attached to the transport lane 210 with play that can move back and forth. As shown in FIG. 2, a stopper 215 for restricting the sliding movement of the stop lever 240 may be provided on the side surface of the transport lane 210 or the like.

  Since the stop lever 240 has the above-described configuration, the blister card 100 follows the progress of the blister card 100 when the blister card 100 advances while the locking claw 241 is inserted into the perforation 132 of the blister card 100. Slide with 100. When the stop lever 240 slides in the same direction as the blister card 100, the gear stop pawl 242 provided on the lever main body 243 of the stop lever 240 is placed on the side surface of the winding gear 250, as shown in FIG. Inserted into the formed tooth. The winding gear 250 does not rotate when the gear stop pawl 242 is inserted into the gear teeth. Further, as described above, the winding gear 250 is interlocked with the drive gear 223 that rotates the drive pinch roller 221 of the pinch mechanism 220. Further, the pinch mechanism 220 is a mechanism for causing the blister card 100 to advance. For this reason, when the rotation of the winding gear 250 stops, the pinch mechanism 220 also stops, and as a result, the progress of the blister card 100 stops. FIG. 7C shows a state in which the gear stop claw 242 of the stop lever 240 is engaged with the winding gear 250 and the rotation of the winding gear 250 is stopped.

  In this embodiment, the gear stop pawl 242 of the stop lever 240 is inserted into the winding gear 250, and this gear stop pawl 242 is attached to the rotating shaft 221a of the drive pinch roller 221. It may be inserted into the drive gear 223 or other gears that are linked to the drive gear 223.

  As shown in FIG. 7 (c), the stop lever 240 is designed to stop the movement of the blister card 100 at an appropriate position. The “appropriate position” for stopping the progress of the blister card 100 here means that the lid sheet 120 is peeled off from the base sheet 110, only one blister 111 is opened, and the one blister opened. Reference numeral 111 denotes a position facing the suction port 231 of the air piece 230. Thus, by stopping the blister card 100 in conjunction with the progress of the blister card 100, the patient can surely open the blisters 111 one by one. When the blister 111 faces the suction port 231 of the air piece 230 and the progress of the blister card 100 stops, the patient can hold the air piece 230 and inhale the medicine in the blister 111 through the suction port 231.

  When the inhalation of the medicine is completed, the locking claw 241 of the stop lever 240 is released from the hole of the perforation 132 inserted at the present time. Thereafter, the locking claw 241 of the stop lever 240 is inserted into the next hole of the perforation 132. In this way, as the blister card 100 advances, the blister card 100 stops moving whenever the blister 111 reaches a position facing the suction port 231 of the air piece 230. The configuration for releasing the locking claw 241 of the stop lever 240 from the hole of the perforation 132 is not shown. The mechanism for releasing the locking claw 241 of the stop lever 240 can be realized by a simple mechanism that lifts the stop lever 240 slightly upward. For example, a configuration in which the stop lever 240 is lifted upward when the medicine inhalation is completed may be provided. For example, although not shown in the drawings, the casing of the inhalation device 200 can be provided with an openable / closable cover for covering the air piece 230. When inhaling a medicine, the patient opens the cover of the casing and holds the air piece 230. In addition, the patient closes the housing cover when the inhalation of the medicine is completed. For this reason, when the cover of the housing is closed, a mechanism for lifting the stop lever 240 upward is provided in conjunction with the cover opening / closing mechanism, so that the locking claw 241 of the stop lever 240 can be easily released. Is possible. For example, a protrusion or the like is provided on the lever main body 243 of the stop lever 240, and a protrusion bar is provided on the cover of the housing. When the housing cover is closed, the protrusion bar provided on the housing becomes the stop lever. What is necessary is just to provide the mechanism which cancels | releases the latching claw 241 of the stop lever 240 from the hole of the perforation 132 by contacting the protrusion part 240 and lifting the stop lever 240 upward.

  FIG. 8 shows a state after all blisters 111 included in the blister card 100 have been opened. As shown in FIG. 8, when all blisters 111 are opened, the blister card 100 is positioned in the transport lane 212 on the discharge side. The used blister card 100 has its leading portion protruding from the discharge-side transport lane 212. For this reason, the used blister card 100 can be pulled out by picking the top portion with a finger. Of the used blister card 100, the base sheet 110 and the lid sheet 120 may be discarded. On the other hand, the card base 130 of the blister card 100 can be reused.

It is the perspective view which looked at the card | curd from the front side. As shown in FIG. 9A, in the second embodiment, the blister card 100 includes a base sheet 110 and a lid sheet 120. Unlike the first embodiment, the card base 130 is omitted in the second embodiment. Instead, in the second embodiment, the base sheet 110 and the lid sheet 120 are responsible for the function of the card base 130.

  As shown in FIG. 9A, in this embodiment, perforations 132 are formed on each of the base sheet 110 having a plurality of blisters 111 and the lid sheet 120 bonded to the base sheet 110. Thus, by forming the perforation 132 on the base sheet 110 and the lid sheet 120, the blister card 100 can be set and used in the inhalation device 200 of the present invention. In this case, the base sheet 110 is preferably a thicker sheet than the lid sheet 120. For example, the base sheet 110 is preferably made of hard plastic or the like and has a thickness of about 0.1 mm to 5 mm, or about 1 mm to 3 mm. In this way, by providing the base sheet 110 with a thickness, the locking claw 241 of the stop lever 240 in the inhalation device 200 can be easily inserted into the hole that forms the perforation 132. Also in this embodiment, it is preferable that the front end portion 121 of the lid sheet 120 extends in the longitudinal direction from the base sheet 110.

  In other embodiments, the perforation 132 can be formed only on the base sheet 110, or can be formed only on the lid sheet 120.
