Description

Patient chair for thoracentesis

technical field

The utility model relates to a medical device, in particular to a patient chair for thoracentesis.

Background technique

Thoracentesis is a common clinical operation at present, and it is mainly used for the puncture and drainage of pleural effusion and the puncture biopsy close to the chest mass. Thoracentesis can not only test and examine the puncture specimens to confirm the diagnosis of the disease, but also treat it, reduce the volume of fluid in the pleural cavity, and promote its recovery. Considering the impact of liquid and gas on body position changes, thoracentesis generally requires the patient to sit, and the puncture needle is inserted from the back, side, or front. As the most common clinical operation, there is currently no patient operating chair specially used for puncture.

In most cases, the patient is asked to sit on a common stool for operation. However, due to lack of support or complications during the operation (such as pleural reactions), some patients cannot persist until the operation is completed. Some weak patients may rely on the shoulders or tables of relatives, but this brings a great test to the aseptic requirements of the operation. And because there is no comfortable position, some chronic patients have a certain resistance to thoracentesis.

Therefore, it is necessary to improve the prior art.
