The present invention relates to an inhalation device capable of administering a powdered drug of the present invention to a patient by mouth or nose.

It is already well known that powdered medication is administered to the patient's bronchi by means of an inhalation device having a mouthpiece capable of inhaling the medication through the patient's mouth. The medicament is infused into a gelatin capshoe, the capshoe is inserted into the inhalation device, punched out, and the powdered drug released from the capshoel upon inhalation is administered to the patient through the mouthpiece.

Capshule infiltrated with powdered medicine is generally made of gelatin, which is in the form of elongated torpedo, and consists of two parts, one part (called capshoe body) and the other part (called capshoe cap). Some are sutured.

The contact portion of these two capshoe portions is often formed by the ribs and the demands that the two capshoels are locking together. An inhalation device using such a capshoe usually has a capshoe receiving chamber arranged to receive a capshoe in which the medicament is infiltrated.

An air inlet, or several holes, are laid in the cap-shoulder chamber and the air from the chamber can be sucked through a nozzle that forms part of the chamber.

The air inlet is arranged to release the contents of the perforated capshoe in the receiving chamber and to inhale through the nozzle upon inhalation.

It is an object of the present invention to provide a new suction device which operates more simply than the conventional device.

According to the present invention, there is provided an inhalation device for use in administering a medicament by a capshoe body of a type consisting of a capshoe body and a capshoe cap partially overlapping the capshoe body, and the inhalation device includes: A hollow body consisting of communicating air inlets, a nozzle that allows the patient to inhale air from the capshoe accommodating chamber, and an inlet opening on the outside of the accommodating chamber so that the capshoe can be inserted. Capshoe inserts arranged to weaken the joints between the capshoe body and the capshoe cap by compressing and deforming the overlapping joints of the capshoe body and capshoe cap while retaining the capshoe inserted by a portion of the body Capshoe opening means located inside the seal and guard nets to prevent the separated capshoe body from passing through the nozzle Here, the opening means and the insert can be moved relative to each other, and this relative movement between them causes the protruding fuselage portion of the cap shoal and the opening means to collide with each other to separate the cap shoe cap from the cap shoal fuselage. Is arranged to.

In one embodiment, the hollow body is a cylinder whose one end is open and whose other end is closed, the sealing sleeve being rotatably pushed in the open end of the body.

The hermetic sleeve is formed of a nozzle, a capshoe insert and opening means, and the capshoe insert and the opening means are fitted with the opening means of the projection of the capshoe in which the rotation of the sleeve with respect to the body is inserted into the insert. The capshoe body is positioned in the capshoe receptacle to impinge and separate the capshoe body from the capshoe cap. The capshoe opening means may be an abutment extending into the storage chamber, and the insert is a tub that has an inlet at the end of the sealed sleeve and the projection of the capshoe inserted into the tubus when the sleeve is rotated with respect to the body. Is extended so that it extends to the bell in the chamber in a position against the side of the capshoe rib.

In another embodiment, the fuselage has a nozzle at one end and the sealing sleeve can act on the other end of the fuselage and the insert is a tub, extending through the capwool inlet longitudinally formed in the fuselage to the capshoe receiving chamber and outside the sleeve. Air inlets, the capshoe opening means is a transversely extending bar inside the capshoe receiving chamber.

The capshoe insert may be a tube that is square in cross section and has rounded corners.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1 and FIG. 2, the suction device is usually made of a cylindrical body 1 made of transparent plastics material. The inner side of the cylindrical body is constituted by the cap shoe accommodation chamber 2. One end 3 of the body is sealed.

The other open end of the fuselage is pushed in with a fuselage sealing sleeve 4 which can be rotated on the fuselage. This hermetic sleeve 4 is formed with a nozzle 5 in the form of a mouthpiece for inhalation by mouth, and for convenience of the technique, the nozzle 5 here will be considered to protrude over the front end of the fuselage. .

The patient inhales through the nozzle to withdraw the powdered drug from the capshoot chamber 2 when the capshoot C is separated into two parts as will be described later.

The guard net 6 is installed at the rear end of the nozzle and allows the powdered medicine to be sucked through the nozzle when the patient is inhaled, but the separated capshoe portion is not sucked. The sealing sleeve 4 is axially movable relative to the fuselage 1 and is a peg or plug (after which it is screwed into a threaded slot 8 in the fuselage 1). Called a stopper). The air inlet does not need to extend over the entire length of the chamber but extends over about two thirds of the length of the periphery of the fuselage. Typically two to four air inlets are formed in the body. The air inlet 9 communicates with the cap shoul storage chamber 2 and forms an angle with respect to the diagonal angle of the cap shoul storage chamber. Therefore, when air is sucked through the nozzle, the air flows through the capshoe container chamber while vibrating and rotating all parts of the capshoe separated and introduced into the capshoe container chamber as described later. This allows the powdered drug remaining in the capsule to be released and dispersed into the turbulent air stream and also to disperse the drug in the receiving chamber. In the end, the dispensing agent is administered to the patient through the nozzle.

The opening at the front end of the rotatable hermetic sleeve and its adjacent nozzle is a capshoe insert in the form of a tub or sleeve 10 into which the capshoe can be inserted. The insertion opening 10 is formed to have a length such that the cap shoe body CB protrudes into the storage chamber 2 when the cap shoe is inserted.

The insert 10 may be a separate member that is tightly inserted into the seal sleeve 4 but may be integrally formed with the seal sleeve in such a way that the seal sleeve and the insert are made in a single mold.

As shown in FIGS. 4 and 5, at least one portion of the insert (part 10a) has a square cross section and rounded corners, and the remaining portion 10b of the insert is used for the cap shoal. It has a larger diameter than that for providing an inlet. The size and shape of the portion 10a of the insert 10 is formed to at least press or deform the overlapping joint of the capshoe body CB and the capshoe cap CC.

The capshoe separating or opening means in the form of a rod, rib or other circumferential wall 11 is located at a short distance with respect to the back end of the body 1. This means typically consists of triangles or wedges in cross section. This means is positioned so that the protrusion of the cap shoal is engaged with the side of the means when the cap shoe protrudes from the insert 10 and the sealing sleeve 4 is rotated relative to the fuselage.

This action separates the two capshoe parts.

In use, the capshoe body CB is inserted into the opening of the capshoe insert to position a portion of the capshoe body adjacent to the opening means 11 in the storage chamber. The sealing sleeve 4 of the fuselage is then rotated on the fuselage and the projection of the cap shoal hits the side of the cap shoe opening means. This action deviates the capshoe body from the capshoe cap.

The overlap between the capshoe cap and the capshoe fuselage inserts the capshoe fuselage into the insert, which is already weakened or broken. Since the periphery of the overlapping portion of the capshoe body and the cap is pushed into the insert 10, the capshoe body is deformed enough to weaken or destroy the coupling part, and the protrusion of the capshoe body is separated from the opening or the opening means. As it strikes, it separates from the capshoe cap. Pre-crushing the joints allows the portions of the capshoe to be separated without the risk of permanent deformation to a degree that does not prevent release of the drug from the separated capshoe portions. The separating or opening ribs or rods 11 also help to empty the powdered medicament from the separated capshoe fuselage, which repeatedly impinges on the openings when the capshoe fuselage vibrates the capshoe with air intake through the nozzle. Because it becomes. Vibration and rotation caused by these collisions help to empty the medicament in the cap shoal. If desired, additional rods or ribs (not shown) may be installed as additional impact bars to aid in the operation of emptying the medication from the capshoe.

When using a capshoe, the capshoe cap remains in the insert even after removal of the capshoe. When the next capshoe is inserted into this insert, the previous capshoe cap is pushed into the storage chamber, which remains in the storage chamber until the fuselage of the next capshoe is removed from the storage chamber.

After inhalation, the sealing sleeve 4 is deviated from the fuselage 1 so that the consumed capshoot body part CB can be removed, and the capshoot capshoe cap CC is inserted into the capshoot prepared for the next dose. Is separated from the insertion port (10).

If necessary, the closed end of the fuselage 1 can be made to be deviated or the front closure sleeve 4 of the fuselage can be made to be deviated. If desired, the fuselage may extend beyond the end wall 3 to provide a storage compartment 22 for the capsule the patient wishes to take daily.

In the example of FIG. 6, the suction device typically consists of a cylindrical body made of transparent plastic material.

The inner side of the cylindrical body is composed of a cylindrical capshoe accommodating chamber 13. At the end of the body 12, a nozzle 14 in the form of a mouthpiece for suction by mouth is pushed or integrally formed.

For convenience of description, the nozzles herein will be described as being in front of the body 12. The patient inhales the powdered medicament from the capshoe receiving chamber 13 through the nozzle when the capshoe is separated into two parts as will be described later. The guard net 15 is mounted on the rear surface of the nozzle 14 so that the separated portion of the cap shoul, not the powdered medicine, is not sucked through the nozzle when the patient is inhaled.

The body 12 has several air inlets 16 extending into the length of the capshoe receiving chamber 13. As shown in FIGS. 1 through 3, the air inlet 16 does not extend over the entire length of the receiving chamber, but may extend over about two thirds of the length of the periphery of the fuselage. Typically, two to four air inlets are laid.

The air inlet communicates with the receiving chamber and forms an angle to the diagonal angle of the receiving chamber. Thus, when the air is sucked through the nozzle, the air passes through the chamber while vibrating and oscillating all parts of the separated capshoe in the chamber.

This allows the powdered drug in the capshoe part to be released and dispersed in the turbulent air stream, and also to disperse the powdered drug in the receiving chamber. In the end, the dispensing agent is administered to the patient through the nozzle.

The periphery of the fuselage is also provided with another slot 17 called the capshoe entry slot which spans a portion of the fuselage 12. The capshoe separating or opening means 18 extends across the interior of the capshoe receiving chamber adjacent to the capshoe inlet 17.

The actuating sleeve 13 and the sealing sleeve 19 can slide on the rear end of the body 12. The sleeve 19 is of an inner shape and size that is complementary to the fuselage outer shape and size and is sealed to the rear end wall.

An insertion opening 20, which is made of an opening so that the cap shoul can be inserted and retained, is formed in the wall of the working sleeve 19 in the same structure as the example in FIGS. Insertion opening 20 is sleeve 19 so that opening of insertion opening 20 coincides with cap shoal inlet 17 in fuselage 12 when sleeve 19 is fully inserted into fuselage 12. Is located in.

This insert has a square cross section and a flat edge.

In the modified form in FIG. 7, the suction device is provided with a collision rod 21 in which the separated part of the cap shoul collides when air is drawn through the mouthpiece 14 to assist in emptying the medicament of the cap shoul. have.

In use, the sleeve 19 completely encloses the fuselage, and the fuselage's fuselage is inserted into the opening of the insert 20 to pass through the capeule inlet 17 so that a portion of the capeule fuselage CB is inserted into the receiving chamber. It is located in front of the opening means 18 in the suction direction on the storage chamber 13 side. The sleeve 19 then slides away from the nozzle 14 on the fuselage 12 such that the capshoot protrusion CB abuts the capshoot opening means 18 in the storage chamber. This action deviates from the capshoe body (CB) from the capshoe cap (CC) so that the drug is dispersed into the receiving chamber.

The coupling between the capshoe body and the capshoe cap inserts the capshoe body into the insert so it is already weakened or broken. Pushing the capshoe cap and fuselage into the insert makes the capshoe fuselage sufficiently deformed to weaken or break the joint as desired and the protrusion of the capshoe fuselage hits the opening means and is completely separated. In use, the capshoe cap remains in the insert even after removal of the capshoe. The next capshoe cap is inserted into the insert so that the previous capshoe cap is pushed into the storage compartment.

The intake, sleeve or mouthpiece may deviate from the fuselage to remove the spent capshoe from the fuselage and the capshoe cap may also be disengaged from the insert as it inserts the prepared capshoe for the next dose.
