Embodiment 1

[0029] See figure 2 The present invention discloses a metered spray inhaler, which comprises: a spray mechanism 1, a housing 2, and a sounding mechanism 3.

[0030] The housing 2 is provided with a main cavity 21, a suction cavity 22, and a sounding cavity 23. The suction cavity 22 communicates with the sounding cavity 23; in this embodiment, the suction cavity 22 and the sounding cavity 23 are respectively arranged in the housing 2 On both sides, the suction cavity 22 and the sounding cavity 23 are oppositely arranged.

[0031] The housing 1 is provided with a partition 24 which separates the main cavity 21 from the suction cavity 22 and the sound cavity 23. A part or all of the spray mechanism 1 is arranged in the main cavity 21, the sound mechanism 3 is arranged in the sound cavity 23, and the patient's mouth is aligned with the suction cavity 22.

[0032] The spray mechanism 1 is provided with a spray port 12; the partition 24 has a small hole, and the spray port 12 can pass th...

Embodiment 2

[0036] See image 3 The difference between this embodiment and the first embodiment is that, in this embodiment, the spray inhaler further includes a storage tank 4, which is connected to the inhalation cavity 22, and the patient’s mouth / nose is aligned with the storage tank The inhalation point of 4 (such as image 3 In the far right).

[0037] In summary, the metered-dose inhaler and its casing provided by the present invention are provided with a sounding cavity and sounding mechanism on the casing, and the sound of the sounding mechanism is used to determine the patient's drug inhalation status, thereby knowing whether the patient has successfully administered the drug Inhale.

Abstract

The invention discloses a quantifying aerohaler and a casing thereof. The aerohaler comprises an atomizing mechanism, the casing and a sound generation mechanism, the casing is provided with a main cavity, a suction cavity and a sound generation cavity, the suction cavity is communicated with the sound generation cavity, and a separation layer is arranged in the casing to separate the main cavity from the suction cavity and the sound generation cavity. Partial or all atomizing mechanism is arranged in the main cavity, the sound generation mechanism is arranged in the sound generation cavity, the atomizing mechanism is provided with an atomizing port, a small hole is left on the separation layer, and the atomizing port can right penetrate through the small hole to be communicated with the suction cavity. After the atomizing mechanism is arranged in the main cavity, the suction cavity is not communicated with the main cavity, and the suction cavity enables air to flow through the sound generation cavity. When a user inhales, the sound generation mechanism in the sound generation cavity can make a noise. By means of the quantifying aerohaler and the casing, the sound generation cavity and the sound generation mechanism are arranged on the casing, medicament suction situation of a patient can be judged through sound of the sound generation mechanism, and whether the patient successfully sucks medicaments or not can be further obtained.

Description

Technical field [0001] The invention belongs to the technical field of medical equipment, and relates to a spray inhaler, in particular to a metered-dose spray inhaler; meanwhile, the invention also relates to a housing of the metered-dose spray inhaler. Background technique [0002] The metered-dose inhaler is a tool for metered aerosol (MDI) inhalation therapy. The use of aerosol inhalation therapy has the advantages of small dose, fast action, few side effects, and good effects. At present, the commonly used inhalation devices include manual controlled quantitative aerosol, dry powder inhaler, atomizer powered by oxygen or compressed air, ultrasonic atomizer, etc. Regardless of the spray type, the spray particles must be between 2-5 microns in diameter and can directly enter the bronchioles to achieve corresponding effects. [0003] The structure of the existing metered-dose inhaler is figure 1 As shown, it mainly includes a spray mechanism 1 and a housing 2. The housing 2 incl...
