Mist storage tank facilitating breathing and dosing

Abstract

The invention provides a mist storage tank facilitating breathing and dosing. The tank comprises a mask, a connecting device, a one-way breathing assembly, a front top cover and a mist storage tank body, the mask is installed at one end of the connecting device, one end of the connecting device is fixed to the front top cover, and the one-way breathing assembly is fixed into the other end of the connecting device; the front top cover is installed at the front end of the storage tank body, the rear end cover is installed at the rear end of the fog storage tank body, a dosing one-way valve, an adjusting assembly and a dispersing assembly are sequentially arranged in the mist storage tank body between the front top cover and the rear end cover, and an air inlet assembly is arranged on the side wall of the mist storage tank body between the dosing one-way valve and the adjusting assembly. The interior and exterior of the mist storage tank body are communicated through the air inlet assembly, and a medicine storage assembly is installed on the rear end cover. When a patient inhales medicine mist in the mist storage tank body, the medicine mist in the mist storage tank body cannot be polluted, the patient can breathe more smoothly, and the situation that the quality of the medicine mist in the mist storage tank body is changed due to breathing is prevented.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a spacer for easy breathing and drug administration. Background technique [0002] The spacer is an auxiliary tool for quantitative aerosol inhalation therapy. It is used to store aerosol. curative effect, and reduce its side effects, when the drug mist passes through the spacer, the drug particles and the air in the tank are fully mixed, which solves the problem of asynchronous spraying and inhalation, and can be inhaled several times, inhaling more drug mist, The amount of medicine inhaled into the airway and lung tissue is increased compared with quantitative aerosol alone, and the amount of medicine staying in the oropharynx is significantly reduced, while most of Freon evaporates in the tank, so the curative effect is significantly increased, and the stimulating effect on the oropharynx is greatly reduced. [0003] The structure of the existing spray spacer is re...

AI Technical Summary

Problems solved by technology

[0003] The structure of the existing spray spacer is relatively simple. The publication number is CN203829437U, which provides a high-efficiency inhalation spacer for smoother breathing. By setting a one-way diaphragm, the patient can breathe freely, but the device still has the following problems: Disadvantages: 1. There is only one one-way diaphragm. When the patient inhales the medicine mist and breathes, it is easy to blow the exhaled gas back into the storage tank, which will pollute the medicine mist and increase the internal air pressure. The internal medicinal liquid flows out directly from the vent; 2. When the patient is breathing, the air pressure inside the spacer flows into the vent to ensure the balance of pressure. Since the vent has no filter device, the external gas is easy to pollute the internal medicine mist. Reduce the effect after use; 3. The drug mist is directly sprayed by the quantitative aerosol. Due to the problem of the diffusion rate, the distribution of the drug mist in the spacer is uneven, and the existing spacer cannot be inhaled according to the patient's inhalation. Adjust the cross-sectional area, when the medicine mist is distributed in the spacer, it is easy to cause the patient's medicine dose to be inconsistent every time
