Thoracic tumor hydrops drainage device

Abstract

The invention relates to the field of medical auxiliary instruments, and aims to provide a thoracic tumor hydrops drainage device which is convenient to use and facilitates direction adjustment of a drainage tube. The device comprises an insertion tube inserted into the thoracic cavity, an adjusting head arranged at the upper end of the insertion tube and the drainage tube connected with the adjusting head; the adjusting head comprises a base plate and a hollow rotating block arranged above the base plate, an extending cylinder extending downwards is arranged in the center of the bottom surface of the rotating block, and a connecting tube communicating with the interior of the rotating block is arranged on the side wall of the rotating block and connected with the drainage tube through the connecting tube; and a center hole matched with the extending cylinder is formed in the center of the base plate, and the extending cylinder of the rotating block is inserted into the center hole and rotatably matched with the base plate. The device can effectively shield a wound surface, the access direction of the drainage tube is conveniently changed, and the probability that the drainage tube is pulled can be greatly reduced.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a chest tumor drainage device. 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 remaining fluid is recycled to the blood by the lymphatic system, and the filtration and absorption are in a dynamic balance. If the dynamic balance is disrupted by chest neoplastic lesions, the fluid in the pleural cavity is formed too fast or absorbed too slowly, and when pleural effusion occurs clinically, it is necessary to drain the pleural fluid through a drainage device. [0003] Drainage tubes are always used for drainage of pleural effusions, which...

Problems solved by technology

In actual use, due to the need for the layout of the drainage tube, it is usually necessary to expose the wound near the operation hole and cannot be covered, which will affect the normal heat preservation

At the same time, since the drainage tube needs to be connected with the subsequent closed drainage bottle, negative pressure suction device, etc., the direction of the drainage tube is mainly adapted to the subsequent equipment at present, but this method is less flexible and is likely to cause drag
