Integrated closed chest drainage device

Abstract

The invention relates to an integrated thoracic closed drainage device, comprising a drainage tube, a drainage bag connected to one end of the drainage tube, a cleaning tube with one end connected to the side wall of the other end of the drainage tube, and the other end of the cleaning tube is connected to a cleaning tube. The joint and the protective cap are characterized in that: a coil spring bracket is provided between the inner wall and the outer wall of the other end of the drainage tube, and a scale mark is provided on the outer wall of the other end of the drainage tube, which can prompt the operator Control the proper depth of drainage tube insertion. The invention can ensure that the drainage tube will not be blocked when it is squeezed by the intercostals, and the drainage is smooth; it can also ensure that the drainage tube is fixed reliably, has good airtightness, and will not fall off when the patient moves; the drainage tube and the drainage bag are connected as one, forming a A closed space with a pressure lower than the pressure in the pleural cavity that allows air and fluid to escape and prevents their reflux.

Description

technical field [0001] The invention relates to a medical device, in particular to an integrated closed chest drainage device. Background technique [0002] All kinds of pneumothorax and hemothorax caused by chest trauma require urgent life-saving closed chest drainage. So far, the operation of closed chest drainage is to insert the drainage tube into the pleural cavity and then connect it to the drainage bag or drainage bottle. The drainage tube needs to be fixed with needles and sutures. The main problems are: (1) The wounded must be evacuated to a qualified hospital for surgery; (2) The surgical instruments and necessary equipment are not matched, and they are all temporary combinations; (3) The operation requires the cooperation of multiple people, and does not include preparation work , It takes about 15 minutes for those who are skilled in the operation. [0003] In order to adapt to the rapid first aid of chest wounds in peacetime and wartime, especially in field co...

So far, the operation of closed chest drainage is to insert the drainage tube into the pleural cavity and then connect it to the drainage bag or drainage bottle. The drainage tube needs to be fixed with needles and sutures. The main problems are: (1) The wounded must be evacuated to a qualified hospital for surgery; (2) The surgical instruments and necessary equipment are not matched, and they are all temporary combinations; (3) The operation requires the cooperation of multiple people, and does not include preparation work , It takes about 15 minutes for those who are skilled in the operation.

The above-mentioned closed chest drainage devices have their own characteristics, but there are still deficiencies in ensuring the reliability, patency and airtightness of the drainage tube, and a breakthrough improvement in structure is needed
