Vertical anti-backflow mesh atomization device

Abstract

The invention relates to a vertical anti-backflow sieve atomization device, comprising an upper joint, an upper connecting pipe, a one-way valve, a middle joint, a lower joint, an arc-shaped connecting pipe, an atomization chamber, a liquid inlet device, a lower end cover, an air inlet Connector, intake pipe and counterweight. The upper connector is a T-shaped three-way connector, including two horizontally connected ports and one vertical port. The two horizontally connected ports of the upper connector are respectively connected to the ventilator and the artificial airway. The vertical port of the joint is connected to the upper connecting pipe, the upper end of the upper connecting pipe is connected to the vertical port of the upper joint, the lower end of the upper connecting pipe is connected to the middle joint, and a one-way valve is arranged in the upper connecting pipe, which can prevent backflow in the pipeline , can effectively reduce the chance of infection, the upper end of the nebulizer is equipped with a rotating connection structure, and the lower end of the nebulizer is equipped with a counterweight to ensure that the nebulizer is always in a vertical state when the patient's position changes, and the atomized medicine is always in the atomization state The lowest position of the device reduces the residue of liquid medicine and ensures the effect of atomization.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a vertical anti-backflow sieve-hole atomization device used for the atomization treatment of patients assisted by a ventilator. Background technique [0002] At present, in clinical practice, especially in intensive care units, there are more and more occasions where ventilators are used to help patients breathe. In addition to assisting breathing, ventilators can also be used for nebulization of medicines. In addition to intravenous medication, many special pulmonary infections must also be treated with local atomized inhalation, because local atomized inhalation has a better effect of eliminating phlegm and expectoration. [0003] At present, when performing nebulization therapy on ventilator patients clinically, a T-shaped three-way connector is usually provided. One of the two horizontally connected connectors of the T-shaped three-way connecto...

AI Technical Summary

Problems solved by technology

[0005] (1) Condensed water generated in the pipeline during the nebulization period, cough secretions of the patient's airway, etc. are easily poured into the nebulizer, causing drug pollution and wasting drugs. At the same time, if the substances poured into the nebulizer cannot be cleaned up in time , it will form a bacterial culture medium, which is easy to breed bacteria and increase the risk of infection. The bred bacteria will enter the patient's respiratory tract with the next atomization, causing ventilator-associated pneumonia (VAP) in severe cases, increasing the length of hospital stay and increasing the patient's financial difficulties , increased mortality

[0006] (2) Patients generally use a semi-sitting position when nebulizing, but mechanically ventilated patients often adopt lying positions, 30-degree sitting positions, side lying positions, etc. due to their critical condition and cannot meet the requirements. When changing, it is easy to cause the inclination of the atomizer, and the pressure gas used in the atomization of the existing atomizer usually enters from the lower end of the atomizer. Once the atomizer is tilted, the liquid level in the atomizer will decrease. Tilting occurs, causing the part of the liquid medicine to not be fully atomized, and part of the medicine liquid remains in the atomizer, which cannot be fully utilized, resulting in waste of medicine liquid and affecting the therapeutic effect at the same time

[0007] (3) In the existing atomizer, the pressure gas pipeline is connected to the lower end of the atomizer, and the pressure gas enters from the lower end of the atomizer, which may easily cause the extrusion of the pressure gas pipeline, which will affect the pressure and pressure of the gas entering the atomizer. flow, resulting in poor atomization effect

[0008] (4) In order to improve the effect of nebulization, several medicines should be combined with nebulization in order to improve the nebulization effect on patients. reactions, adverse reactions

With the existing nebulizer, it is necessary to disassemble the medicine cup of the nebulizer every time the medicine is added, which is cumbersome, time-consuming and labor-intensive, and increases the probability of contamination of the medicine and the nebulizer

[0009] (5) At present, nebulizers are commonly used in clinical practice. After atomization, the drug particles are large, and most of the atomized drug particles sink in the nose and throat, and do not enter the lungs of patients. Therefore, the atomization effect is poor and the therapeutic effect cannot be achieved.
