Description

Technical Field

[0001] The utility model relates to the technical field of equipment for thoracocentesis, in particular to a special chair for thoracocentesis. Background Art

[0002] Thoracentesis is an operation in which a sterilized needle is used to puncture the skin, intercostal tissue, or parietal pleura into the pleural cavity. In clinical work in pulmonary medicine, thoracentesis is a relatively common, convenient, and simple diagnostic and treatment method. Thoracentesis can extract fluid or gas in the chest cavity and relieve its compression on the lungs, heart, and large blood vessels. At the same time, relevant examinations of the extracted fluid or gas can help clarify the cause of pleural effusion or gas accumulation.

[0003] At present, various hospitals use different chairs for thoracentesis for patients. There are training chairs, wooden chairs, plastic chairs and other chairs used in daily life. These chairs are used in the patient's thoracentesis treatment operation, so that the patient has an uncomfortable sitting posture during the operation and has to adjust the body position according to the doctor's requirements, which is very strenuous and unsafe. At the same time, due to the inappropriateness of the chair, the doctor's operation is also subject to certain restrictions. In order to solve the problem of patients' uncomfortable sitting posture during the puncture process and the inconvenience caused by the chair during the doctor's operation.
