Integrated thoracic close drainage device

Abstract

The invention relates to an integrated thoracic close drainage device which comprises a drainage pipe, a drainage bag connected with one end of the drainage pipe and a cleaning pipe with one end communicated with the other end of the drainage pipe. The other end of the cleaning pipe is connected with a cleaning connector and a protecting cap. The integrated thoracic close drainage device is characterized in that a spiral spring support is arranged between the inner wall and the outer wall of the other end portion of the drainage pipe, a scale mark is arranged on the outer wall of the other end of the drainage pipe, so that an operator is prompted to control the drainage pipe to be inserted at a proper depth. According to the integrated thoracic close drainage device, drainage is smooth when the drainage pipe is squeezed by the intercostal space and the drainage pipe is not blocked are guaranteed, and the drainage pipe is fixed reliably, the integrated thoracic close drainage device is good in sealing performance, and does not fall off when a patient moves are guaranteed. The drainage pipe and the drainage bag are connected into a whole, a sealed space with pressure smaller than the internal pressure of the pleural cavity is formed, the gas and fluid in the pleural cavity can be discharged, and the gas and the fluid are prevented from flowing backwards.

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 fiel...

Problems solved by technology

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
