A drainage device for pleural effusion and exhaust

Abstract

The invention discloses a drainage device for pleural effusion and exhaust, which mainly includes a puncture needle body, a puncture fixing device, a puncture positioning device, a drainage device, an infusion device, and a propeller. The puncture position is adjusted to improve the positioning accuracy, the puncture needle body is fixed by the fixing device, the three-way valve and the speed control valve are adjusted during drainage, and the exchange of pleural effusion or exhaust process is realized, and the pusher is used during puncture The device drives the rebound device composed of fixed plate 1, fixed plate 2 and springs, which can quickly puncture and pull out the needle core. The infusion device can clean and administer the chest cavity, and realize the seamless exchange process of effusion and exhaust. stitching. In a word, the present invention is reasonable in design, accurate in positioning, safe and reliable, less irritating to patients, and convenient in operation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a drainage device for pleural effusion and exhaust. Background technique [0002] There is 3-15ml of fluid in the pleural cavity of normal people, which acts as a lubricant during breathing movements, but the amount of fluid in the pleural cavity is not constant. Even for normal people, 500-1000ml of liquid is formed and absorbed every 24 hours. The fluid in the pleural cavity is absorbed from the venous end of the capillaries, and the rest of the fluid is recycled to the blood by the lymphatic system. Filtration and absorption are in a dynamic balance. If the dynamic balance is destroyed due to systemic or local diseases, the fluid in the pleural cavity will form If the absorption is too fast or too slow, pleural effusion will be produced clinically, which will compress the lungs or the pleural effusion will take a long time. When the patient has defects in the chest w...

Problems solved by technology

In clinical work, thoracentesis is a relatively common, convenient and simple method of diagnosis and treatment. When puncture drainage of pleural effusion or pneumothorax is performed, continuous drainage of pleural effusion or gas and expansion of lung tissue may cause The needle tip damages the alveoli and triggers iatrogenic pneumothorax. Clinically, for fear of the needle tip damaging the heart or lung tissue, the relevant drainage can only be terminated early

In the prior art, the effusion or gas in the pleural cavity is only drained separately, and the whole process is highly infectious. After the drainage, when the extraction site needs to be cleaned or drug treatment is required, it must be punctured again, which cannot be timely Effective drug treatment on the extraction site will aggravate the patient's condition and prolong the patient's healing time, which is not conducive to physical recovery
