Problems solved by technology

Therefore, the conventional drug ejection device involves unsolved problems, because when the patient inhales the drug, the inner wall of the air flow path in the device is contaminated, and the parts including the air flow path themselves have to be removed and cleaned or replaced with new parts

Embodiment 1

[0039] like figure 1 As shown, the inhalation device in this embodiment has a device main body 1, a flow path member 3 supported on the device main body 1, a mouth member 2, and an inner wall surface component 5, and the inner wall surface component 5 is detachably fitted in the flow channel. in road component 3.

[0040] The inner wall surface constituting member 5 is formed detachably from the flow path member 3 and the mouthpiece 2 , and the mouthpiece 2 is formed so as to be detachable from the device main body 1 . Since at least a part of the inner wall surface constituting member 5 is made of a flexible material, the member can be easily attached to or detached from the flow path member 3 and the port member 2 .

[0041] It is worth noting here that, in this specification, the "inner wall surface component" can be any component that can prevent the drug from directly adhering to the inner wall of the flow path component, especially one that is detachable from the flow p...

Embodiment 2

[0052] A perspective view of an inhalation device in a second embodiment of the invention as Figure 4 as shown, Figure 5 show Figure 4 Cross-section of the inhalation device shown.

[0053] In this embodiment, the inner wall surface constituting member 5 in Embodiment 1 is replaced by a thin film 12 . The film 12 as an inner wall surface constituent member is in close contact with the inner wall surface of the airflow path constituting a part of the surface of the flow path member 3, and thus hardly affects the shape of the airflow path. Therefore, regardless of whether the air flow path is provided with the membrane 12, the air flow caused by inhalation does not change, and a similar inhalation state can be realized. After the inhalation is finished, when the user peels off the film 12 with the drug attached, the drug attached can be removed from the airflow path, and a new inner wall of the airflow path is formed after the film is peeled off.

[0054] It is preferred ...

Embodiment 3

[0063] The perspective view of the inhalation device in the third embodiment of the present invention is as Figure 7 shown. Figure 8 show Figure 7 A cross-section of the inhalation device shown in .

[0064] The arrangement in this example does not include peeling off the film 12 in Example 2, but turns back the sheet 15 as an inner wall surface constituent member in the airflow path after inhalation. A plastic sheet having a degree of softness that allows easy manual folding is used as the sheet 15 . The sheet 15 is in close contact with the inner wall surface of the airflow path, and hardly affects the shape of the airflow path. Therefore, regardless of whether the air flow path is provided with the sheet 15 or not, the air flow caused by the suction does not change, and the same suction state can be realized. After the inhalation is finished, when the user lifts the sheet grip 16, the sheet 15 is folded along the cut portion 17, and the surface constituting the inner...

Abstract

In a medicine ejection device for administering a medicine to the throat, bronchi or lungs, the air flow path to which the medicine has stuck is to be kept in clean state in a simple configuration. The medicine ejection device which ejects a medicine to be inhaled by a user via a suction port, including a flow path member linked to the suction port and capable of forming an air flow path in which the medicine is guided by the inhalation by the user to the suction port, and an internal wall face constituting member which is intended for formation of the internal wall of the air flow path and allows detachable fitting in the flow path member.

Description

technical field [0001] The present invention relates to a medicine ejection device which ejects medicine inhaled by a user. Background technique [0002] The medicine ejection devices disclosed in International Publication Nos. WO95 / 01137 and WO02 / 04043 have been used to achieve user therapy in combination with information databases including electronic medical records. Such a medicine ejection device has a storage unit for storing personal information of users including their medical records and prescriptions. These medicine ejection devices are also portable terminals that also serve as inhalation devices with medicines inhaled by the user. Such a medicine ejection device also has an ejection control unit that controls the inhalation device and ejects medicine according to each user's inhalation profile to allow the user to inhale the medicine according to prescription information. [0003] In such a drug ejection device, there is generally a passage through which the sp...
