Description

Technical Field [0001] The present invention relates to a disposable powder inhaler,

The present invention relates to a method of manufacturing a disposable powder inhaler for storing and providing powder.

Agents for the treatment or prevention of asthma or chronic obstructive pulmonary disease are generally provided in powder form and can be fed directly into the lungs or lungs through the inhalation of the powder. A powder inhaler for supplying the medicament is disclosed in Patent Publication No. 10-1996-0706361 (publication number). Replaceable cartridges can be used to deliver the right amount of powder each time you use it, and you can prevent the supply of deteriorated medicines by supplying new medicines every time.

In addition, in Patent Publication No. 10-2005-0042138 (publication number), it is noted that patients suffering from diseases such as severe asthma have difficulty in inhaling the powder, and in order to facilitate pulmonary infiltration of the powder, A powder inhaler that implements pulverization is disclosed.

However, the powder inhalers disclosed in the above-mentioned patents may provide an appropriate amount of powder or aid in the improvement of the suction, but may be configured to discharge other powder except for the cartridge or container containing the powder to the outside Mouth piece, weighing member, sliding protecting member) are all provided through a complicated assembling process, and it is difficult to avoid an increase in the process time for production and an increase in the production unit price.

Especially, since the medicine for treating or alleviating the lung disease is small in size and the contents are powder, the airtight condition is very important because it can easily change when in contact with air. However, the powder inhaler disclosed in the above-mentioned patents has a problem that the powder is inevitably recycled each time and the powder remains in the inhaler, and the risk of deterioration of the remaining medicine remains.

The present invention provides a manufacturing method capable of safely protecting powders vulnerable to deterioration due to external exposure and capable of providing a disposable powder inhaler capable of lowering the production cost by eliminating complicated structures for improving the powder or discharging a fixed amount .

In addition, in the conventional powder inhaler, there is a problem that the powder having high adsorbability remains on the inner wall of the component of the inhaler, and there is always a risk of inhaling the weakened drug by recycling it every time. The present invention provides a method of manufacturing a disposable powder inhaler capable of improving the above problems.

According to one exemplary embodiment of the present invention, a method of manufacturing a disposable powder inhaler includes the steps of: stacking a first sheet and a second sheet of flexible synthetic resin; Blowing between the first sheet and the second sheet; The first and second sheets are fused to form an air inlet and outlet space communicating with the powder accommodation space and the powder accommodation space, and an air inlet and an air outlet for communicating the air inlet and outlet space with the outside are formed, Providing a powder receiving body through which external air is discharged through the air inlet discharge space and the powder receiving space together with the powder through an air volute; And injecting the powder into the powder receiving space.

Two sheets of plastic sheets are superimposed and the two sheets are pressed up and down in a state in which air is blown between the sheets in order to maintain the spaced apart state for the powder accommodation space or the air inflow and discharge space. A powder accommodation space or an air inflow / discharge space is formed inside the fused portion, and an air inlet and an air volley are provided through the unfused portion.

It is possible to provide a disposable powder inhaler simply by providing a powder receiving body for receiving the powder through the compression of two plastic films and by injecting the powder into the inside of the powder receiving body.

In addition, the conventional powder inhaler has components for discharging powder in addition to the cartridge for storing the powder, and by manufacturing the powder through a complicated assembly process, a high production cost may be a problem, and a fine powder powder The disposable powder inhaler according to the present invention has a structure for sucking or discharging powder into the powder-receiving body, and a structure for sucking or discharging the powder-receiving body is provided in the powder- It is provided as a disposable container in which the use itself is excluded and the risk of residual powder can be solved.

On the other hand, the first and second sheets can be fused to provide a partitioned partition wall inside the powder receiving body, which can divide the air inlet and discharge space with the air inlet and the air balloon interposed therebetween.

The moving direction of the air flowing into the powder inlet space by the partition wall may be changed into the powder receiving space. That is, the air entering the air inlet is not directly discharged to the air volute, but moves toward the powder provided in the powder receiving body, thereby facilitating the discharge of the powder.

In addition, the partition wall may be formed to extend from the powder receiving space to the powder receiving space and the communication portion of the air inflow / discharge space. When the moving direction of the air flowing through the air inlet into the powder receiving space passes through the end of the partition wall A vortex can be formed in the powder receiving space by vertically changing the powder receiving space, and the powder provided in the powder receiving body is effectively discharged by the vortex, thereby minimizing the amount of the residual powder.

The partition walls may be formed together by pressing the first and second sheets to form the powder accommodation space and the air inlet / exhaust space, but they may be formed separately. Further, the partition wall can be formed before or after the powder is injected into the powder accommodation space.

The injection of the powder may be carried out through the non-fused portion left for injecting the powder in the step of fusing the first and second sheets, and the nozzle for powder scanning may be inserted into the non-fused portion. Therefore, the inlet for inserting the nozzle may be sealed by fusion or another cover paper.

In addition, in the step of fusing the first and second sheets, the air inlet and the first and second sheets adjacent to the air ball are fused together to form the air inlet and the cut-off inducing body for temporarily blocking the air ball .

Although the air inlet and the air volleyball can be shut off by using a separate cover, it is possible to cut off the air inlet and the air volleyball simply by welding, and the cut-off induction body which can be easily removed from the powder receiving body through the fusion process The preparation for powder inhalation can be minimized. Preferably, the cut-out induction body is formed by flattening it so that it can be twisted off by hand.

The cut-off induction body is connected to the fused portion around the air inlet and the air volleyball by fusion, so that the air inlet and the air volleyball can be opened naturally when they are twisted out.

Meanwhile, in the process of injecting the powder into the powder receiving body, an unfused region provided for inserting and withdrawing the nozzle for powder scanning in the process of fusing the first and second sheets can be used. After the powder is injected, And the opening which is opened for removal can be sealed by fusing or separate covering.

According to another exemplary embodiment of the present invention, the disposable powder inhaler includes an air inflow / discharge space communicating with the powder accommodation space and the powder accommodation space through fusion of the first and second sheets, And external air introduced into the air inlet can be discharged through the air inlet and outlet space and the powder receiving space together with the powder through the air volleyball.

Conventional powder inhalers have a component for discharging powder in addition to a cartridge for storing powders, and they are manufactured through a complicated assembly process, so that a high production cost may be a problem. However, the disposable powder inhaler according to the manufacturing method of the present invention can provide the disposable powder inhaler in an integrated form through the compression of two plastic films. That is, it is possible to omit a complicated process of preparing various components and assembling them as in the prior art, so that it is possible to reduce the production time and production cost, and also to reduce the defective rate that occurs during assembly. In addition, since a plurality of powder inhalers can be produced at once through fusion, it is advantageous in cost reduction through mass production.

In addition, the conventional powder inhaler is provided with fine powder powders by reusing components for discharging powder other than the cartridge for storing powders, so that the possibility of inhaling the deteriorating agent due to reuse due to the nature of the drug having a high internal adsorption ratio remains . However, the powder inhaler of the present invention, which can be produced at low cost by squeezing a plastic sheet and excludes reusing itself, can be provided as a disposable container to solve the risk of residual powder.

In addition, the powder inhaler of the present invention forms a vortex at a place where the powder is stored through a partition wall that changes the moving direction of the air flowing into the powder accommodation space through the air inlet to the powder accommodation space, And the amount of residual powder can be minimized.

In addition, the powder inhaler of the present invention can be easily peeled off before use by forming a cutout inducing body for opening and closing an air inlet and an air volute through fusion, thereby enhancing ease of use.
