Drainage instrument for thoracic surgery

Abstract

The invention discloses a drainage instrument for the thoracic surgery department, and relates to the technical field of drainage devices.The instrument comprises a supporting plate and a negative pressure drainage device assembly, wherein the negative pressure drainage device assembly is fixedly connected to the top of the supporting plate; a drainage tube is installed on the top of the negative pressure drainage device assembly, and one end of the drainage tube is fixedly connected with a fixing tube in a sleeved mode. A threaded pipe is fixedly connected to the fixed pipe in a sleeving mode, a rotating cylinder is connected to the threaded pipe in a threaded mode, a first pressing ring is arranged at the bottom of the rotating cylinder, and a plurality of first spring rods which are evenly distributed are fixedly connected to the bottom of the first pressing ring. According to the device, the drainage tube is inserted into a surgical wound, the main fixing base is buckled on the body of a patient, and the joint of the wound and the drainage tube is shielded; then a rotating cylinder is rotated to drive a second pressing ring to press a main fixing seat, so that a first adhesive ring is adhered to the body of the patient, and the drainage tube is fixed; meanwhile, the wound is sealed, and air leakage is prevented.

Description

technical field [0001] The invention relates to the technical field of drainage devices, in particular to a drainage device for thoracic surgery. Background technique [0002] Closed pleural drainage is one of the most important treatment methods in clinical thoracic surgery. The purpose of closed pleural drainage is to drain the gas and fluid in the pleural cavity to the outside, restore the airtightness of the pleural cavity and restore the normal negative pressure of the pleural cavity. To stabilize the mediastinum and promote lung recruitment, for this reason, chest drainage must be a closed drainage system, and the entire drainage device and drainage catheter must be a closed drainage system that cannot communicate with the outside world to prevent air leakage from causing danger. Some chest drainage devices can be divided into three types: single bottle, double bottle and three bottle combined type from the structural composition. [0003] The existing drainage device...

AI Technical Summary

Problems solved by technology

[0003] The existing drainage device for thoracic surgery is simple in structure, and the connection between the suction tube and the patient's thoracic surgery wound is not stable enough. Since most treatment methods require drainage for a long time and multiple times, the drainage device will always be attached to the surrounding area for a period of time. On the patient's body, when the patient needs to turn over, get out of bed or cough violently, the suction tube that is not connected stably will deviate, and even cause air leakage, leading to medical accidents
