Medical anti-pollution thoracentesis device

Abstract

The invention discloses a medical anti-pollution thoracentesis device. The device comprises an outer cannula (1) and an inner puncture needle (2), and the outer cannula (1) is a hollow tube with two closed ends; a needle tip puncture end of the inner puncture needle (2) is a front end, the rear end of the inner puncture needle (2) penetrates through the rear end surface of the outer cannula (1) and is arranged out of the outer cannula (1), and the front end of the inner puncture needle (2) is arranged in the outer cannula (1) and is in sliding contact with the outer cannula (1); the outer cannula (1) is internally provided with an empty cavity (3) and a disinfection solution cavity (4), the empty cavity (3) is close to the inner front end of the outer cannula (1), the disinfection solutioncavity (4) is close to the inner rear end of the outer cannula (1), and a middle clapboard (5) is arranged between the empty cavity (3) and the disinfection solution cavity (4). According to the technical scheme, the blood is blocked by a blood blocking stent, and therefore a clear surgical field is obtained; the structure is simple, and the blocking effect is good.

Description

technical field [0001] The invention relates to a medical anti-pollution thoracentesis device, which belongs to the field of medical instruments. Background technique [0002] Pericardial effusion and pleural effusion are common medical diseases. Pleural effusion is the excessive leakage or exudation of interstitial fluid on the surface of the pleura and accumulation in the pleural cavity, commonly known as pleural effusion. Pleural effusion is not a disease but a consequence of systemic or pleural disease. Its symptoms include pleuritic chest pain and shortness of breath; therefore, the extraction of pleural effusion can reduce the pressure of liquid on the lung tissue, re-expand the lung tissue, and relieve the patient's dyspnea and other symptoms. In the case of field first aid, if the patient’s body is inconvenient to move, it is necessary to extract pleural effusion in a complex environment in the field. Before extracting pleural effusion, it is generally necessary to...

AI Technical Summary

Problems solved by technology

In the case of field first aid, if the patient's body is inconvenient to move, it is necessary to extract pleural effusion in a complex environment in the field. Before extracting pleural effusion, it is generally necessary to disinfect the pleural epidermis, but sometimes The wind and sand are relatively large, and the disinfected epidermis is easily polluted

Moreover, after the thoracentesis needle is taken out, the puncture needle will be exposed to the air in the field for a long time, causing pollution of the puncture needle, and because the field environment is relatively complicated, pollutants are likely to self-puncture the needle hole during the puncture process. Into the patient's internal tissue, easy to cause puncture infection
