Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a cap assembly and an inhalation device. Background Technology

[0002] Treating patients with medications contained in aerosols is well-known, for example, in the treatment of respiratory diseases. It is also known that medications for such treatment are contained in aerosols and administered to the patient via an inhalation device comprising a mouthpiece and a housing containing an aerosol canister. Such inhalation devices are commonly referred to as metered-dose inhalers (MDIs). The aerosol canister used in such inhalation devices is designed to deliver a predetermined dose of medication each time it is actuated by means of an outlet valve member (e.g., a metering slide valve) at one end, which can be opened by pressing down the valve member while the canister is stationary or by pressing down the canister while the valve member is stationary. When using such a device, the aerosol canister is placed in the housing, and the outlet valve member of the canister communicates with the mouthpiece. When used to dispense medication (e.g., in bronchodilator therapy), the patient holds the housing generally in an upright position and places the mouthpiece of the inhalation device in the patient's mouth, then actuates the aerosol canister to dispense a dose of medication from the canister, which is then inhaled by the patient.

[0003] To prevent bacteria, dust, and other impurities from entering the mouthpiece of an inhaler, the known method is to use a cap to seal it, thus preventing dust and dirt from entering. Currently, most caps are separate from the inhaler body, which makes it very easy for the cap to be lost during carrying or use, affecting subsequent use. Utility Model Content

[0022] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0023] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0024] See Figures 1 to 3 As shown, this utility model provides a cover assembly, which is disposed on the inhaler body 1, for selectively isolating the mouthpiece 2 from the external environment to prevent moisture and dust from entering.

[0025] Specifically, the cover assembly 7 includes a strap 71 and a dust cover 72. The strap 71 is constructed as a multi-segment, bendable structure, with its two ends connected to the inhaler body 1 and the dust cover 72, respectively. The dust cover 72 is adapted to the shape of the mouthpiece 2 and can be locked in place with the inhaler body 1 when the inhalation device is in storage configuration. This cover assembly 7, by using the strap 71 to connect the dust cover 72 to the inhaler body 1 as a single unit, effectively solves the problem of the cover being easily lost after the inhalation device is opened, making it convenient to carry and use.

[0026] In some embodiments, the belt 71 is provided with at least two grooves 711 spaced apart along its length to facilitate segmented bending of the belt 71, thereby making it easier to adjust the position of the dust cover 72.

[0027] Furthermore, the cross-section of the groove 711 is trapezoidal or arc-shaped, and its depth is 1 / 3 to 1 / 2 of the thickness of the band 71, so as to ensure sufficient connection strength while meeting the bending conditions.

[0028] In some embodiments, one end of the band 71 is integrally formed with the inhaler body 1, and a flipping part 712 is provided at the connection between the two to facilitate the flipping of the end of the band 71.

[0029] Furthermore, the cross-section of the flipping part 712 is a "human" shaped structure, and its thickness is 1 / 3 to 1 / 2 of the thickness of the band 71, so as to ensure sufficient connection strength while meeting the flipping requirements.

[0030] In some embodiments, the other end of the strap 71 is provided with a second buckle hole 713, and one side of the dust cover 72 is provided with a second locking block 721. The strap 71 and the dust cover 72 are connected and fixed through the second buckle hole 713 and the second locking block 721, so that the dust cover 72 is integrated with the inhaler body 1.

[0031] In addition, a detachment groove 722 is provided at the connection between the belt 71 and the dust cover 72. The detachment groove 722 overlaps with part of the belt 71, and its distance from the second locking block 721 is less than the thickness of the belt 71. Once the dust cover 72 and the belt 71 are engaged, the detachment groove 722 will restrict the belt 71 from detaching from the second locking block 721, thereby ensuring the reliability of the connection.

[0032] In some embodiments, a plurality of interference ribs 723 are provided on both sides of the inner wall of the dust cover 72. The interference ribs 723 are used to contact and fix with the nozzle 2, thereby enhancing the tightness of the connection between the dust cover 72 and the nozzle 2.

[0033] In some embodiments, the dust cover 72 has an extension cover 724 on the side away from the strap 71, and the extension cover 724 is configured to snap into and secure the inhaler body 1 when it is fitted onto the mouthpiece 2.

[0034] Specifically, the inhaler body 1 is provided with an arc-shaped groove 12, and the extension cover 724 is provided with an arc-shaped protrusion 725 that corresponds to the arc-shaped groove 12. After the dust cover 72 is put on the mouthpiece 2, the extension cover 724 can be locked on the inhaler body 1 by the arc-shaped protrusion 725 cooperating with the arc-shaped groove 12, thereby improving the fixing effect of the dust cover 72.

[0035] In addition, a counting module 5 is provided on the top of the inhaler body 1. The counting module 5 includes a downwardly extending decorative plate 514. When the dust cover 72 is fitted on the mouthpiece 2, the decorative plate 514 abuts against the dust cover 72 to prevent the counting module 5 from being triggered, thus preventing accidental activation caused by accidental contact or collision, thereby causing the counting module 5 to perform dose counting or the inhalation device to deliver drug formulation.

[0036] In addition, this utility model also discloses an inhalation device, including the aforementioned cover assembly 7.
