Description

Respirator switching device

The invention belongs to a respirator auxiliary accessory, especially a three-way tube structure, which enables medical staff to cut off the passage between the patient and the respirator when replacing the respirator, and change to a passage with an air filter for breathing , In order to prevent the virus from infecting the respirator switching device of the medical staff from the respirator department.

According to this, patients with lung disease must use respirators to maintain their respiratory system when necessary. Among them, patients with severe special infectious pneumonia (Severe Pneumonia with Novel Pathogens) or acute respiratory distress syndrome (Acute Respiratory) Distress Syndrome) patients are even more dependent on respirators.

However, after a period of use, the respirator must be cleaned and maintained, and the connection between the patient and the respirator must be temporarily cut off. However, when the connection between the patient and the respirator is cut off, infectious sputum and droplets may be spread from the patient’s pharynx through the respirator tube into the air, causing the medical staff to be exposed to the victim. At risk of infection.

In view of the above problems, the Taiwan Thoracic and Intensive Care Medicine Association currently recommends that when cutting off the connection between the patient and the respirator, hemostatic forceps should be used to clamp the respirator tube in the patient’s pharynx at the same time, or the respirator tube should be clamped. Fold back, or cover the mouth of the respirator tube with your fingers, to block the contact between the respirator tube and the outside world, and reduce the possibility of sputum and droplets being spread into the air through the respirator tube.

However, the above-mentioned prior art still has medical risks. For example, the patient may develop a pneumothorax, or cough and cause the virus aerosol to spread, or cause the patient’s endotracheal tube (Endotracheal Tube) to rupture. Under the premise of causing pneumothorax, coughing, or damage to the endotracheal tube, providing a respirator accessory that reduces the infection of medical staff is still an urgent problem to be solved.
