Clinical closed drainage device for general thoracic surgery

Abstract

The invention relates to the field of medical instruments, in particular to a clinical closed drainage device for general thoracic surgery. The clinical closed drainage device comprises a wearing frame and a drainage bottle arranged in the wearing frame, a conical arc cover is clamped to the top of the wearing frame, the rear portion of the conical arc cover is hinged to the edge of the top of thewearing frame in a matched mode, the inner side wall of the conical arc cover is in contact fit with the side wall of the top of the drainage bottle, plastic ear hook pieces are evenly arranged on the outer side wall of the circumference of the wearing frame, the bottoms of the plastic ear hook pieces are not in contact with the outer side wall of the circumference of the wearing frame, fixing bands are fixedly connected to the outer sides of every two adjacent plastic ear hook pieces, and a cover body is in threaded connection with the top of the drainage bottle. The clinical closed drainagedevice is simple in structure and convenient to carry and use, the section, located at the top of the cover body, of a drainage tube is tightly pressed in a rectangular groove, so that the middle ofthe drainage tube is closed, external gas cannot enter the thoracic cavity of a patient from the bottom end of the drainage tube, and meanwhile the long drainage tube can be conveniently stored between the plastic ear hook pieces and the wearing frame, and the long drainage tube is prevented from hindering the normal movement of the patient.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a clinical closed drainage device for general thoracic surgery. Background technique [0002] After thoracotomy, due to the huge cavity remaining in the thoracic cavity after organ resection, the pressure in the thoracic cavity increases. Negative pressure, restore the preoperative negative pressure state in the thoracic cavity, and promote the expansion of the remaining lung. Clinically, patients with pleural hemorrhage, effusion, and pneumatosis need to use closed chest drainage bottles to drain blood, fluid, and air, so as to achieve the purpose of eliminating dead space, reducing tension and exhausting, and relieving pain. [0003] At present, closed thoracic drainage is to put one end of the drainage tube into the chest cavity, and the other end is connected to a water-sealed bottle (ie, drainage bottle) lower than its position, so as to discharge gas or collect fluid in the ...
