Medical treatment is with anti-pollution thorax puncture device
Technical Field
The invention relates to an anti-pollution thoracentesis device for medical treatment, and belongs to the field of medical instruments.
Background
Pericardial effusion and pleural effusion are common medical clinical diseases. Pleural effusion is fluid that leaks or seeps out of the interstitial fluid on the pleural surface and accumulates in the pleural cavity, commonly known as pleural fluid. Pleural effusion is not a disease but a consequence of a systemic disease or pleural disease. Symptoms include pleural chest pain and shortness of breath; therefore, the extraction of the pleural effusion can relieve the oppression of the liquid to the lung tissue, lead the lung tissue to be refolded and relieve the symptoms of dyspnea of the patient and the like. Under the condition of open-air first aid, if the inconvenient removal of patient's health needs to carry out the extraction of pleural effusion under the complicated environment in the field, before the extraction pleural effusion, generally will disinfect the thorax epidermis to operate, but open-air environment is wind sand great sometimes, and the epidermis after the disinfection receives the pollution very easily. And after the thoracic cavity puncture needle is taken out, the puncture needle can be exposed to the air in the field for a long time, so that the pollution of the puncture needle is caused, and the pollution is easy to enter the tissues in the body of a patient from the puncture needle hole in the puncture process due to the complex field environment, so that the puncture infection is easy to cause.
