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.

Abstract

The invention relates to a vertical anti-backflow sieve pore-type novel atomizing device. The vertical anti-backflow sieve pore-type novel atomizing device comprises an upper connector, an upper connecting pipe, a check valve, a middle connector, a lower connector, arc-shaped connecting pipes, an atomizing chamber, a liquid inlet device, a lower end cover, an air inlet connector, an air inlet pipe and a counterweight, wherein the upper connector is a T-shaped three-way connector and comprises two horizontally communicated interfaces and a vertical interface; the two horizontally communicated interfaces of the upper connector are connected with a respirator and an artificial airway respectively; the vertical interface of the upper connector is communicated with the upper connecting pipe; the upper end of the upper connecting pipe is connected with the vertical interface of the upper connector; the lower end of the upper connecting pipe is connected with the middle connector; the check valve is arranged inside the upper connecting pipe; the check valve can prevent backflow in a pipeline and can effectively reduce the occurrence probability of infection; a rotary connecting structure is arranged at the upper end of an atomizer, and the counterweight is arranged at the lower end of the atomizer. When the body position of a patient changes, the atomizer is guaranteed to be always in a vertical state and atomized medicinal liquid is guaranteed to be always at the lowest position of the atomizer, so that the residual of the medicinal liquid is reduced and the atomizing effect is guaranteed.

Description

Technical field: [0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a novel 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 ...
