Closed thoracic drainage device and drainage bag

Abstract

The invention discloses a closed thoracic drainage device and a drainage bag thereof. The closed thoracic drainage device comprises a drainage tube and a guide needle, wherein a main tube cavity is formed in the middle of the drainage tube, and the guide needle is used for assisting the drainage tube in entering the thoracic cavity; a first branch tube and a second branch tube are arranged at oneend, far away from an inlet end, of a main tube of the drainage tube; a first screw socket is arranged at a leading-out end of the main tube; a second screw socket is arranged at one end of the firstbranch tube; a liquid injection soft valve is arranged at one end of the second branch tube; a ball release bag and a limit clamp are arranged on the outer curved surface of the tube wall of the maintube; and a first medicine cavity and a first liquid injection cavity are formed in the tube wall of the main tube. The closed thoracic drainage device is scientific and reasonable in design and simple and convenient to operate, the drainage tube is bluntly separated into a human body by the guide needle, wounds can be decreased, surgical incisions are small, postoperative scars are not obvious, the wounds are small, minimally invasive effects are achieved, falling or sliding displacement of the drainage tube can be avoided by the aid of the ball release bag and the limit clamp, and risks canbe further reduced.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a closed chest drainage device and a drainage bag thereof. Background technique [0002] Closed thoracic drainage is a technique widely used in thoracic surgery and an effective method for treating spontaneous pneumothorax, pleural effusion, empyema, and traumatic pneumothorax. Based on the principle of differential pressure drainage, it is an important measure to drain gas and fluid in the pleural cavity, reconstruct after thoracotomy, maintain negative pressure in the pleural cavity, and promote lung expansion. Its purpose is to better improve the negative pressure of the chest cavity, discharge air, blood, and fluid from the pleural cavity, prevent its reflux, promote lung recruitment, and close the pleural cavity; it can also balance pressure, prevent mediastinal displacement and Compression of the lungs. [0003] The operation steps of the traditional closed thora...

AI Technical Summary

Problems solved by technology

[0003] The operation steps of the traditional closed thoracic drainage operation are relatively cumbersome. During the operation, the drainage tube is placed in the chest cavity, and then connected to the drainage bag / water-sealed bottle, which causes relatively large trauma to the patient, and subcutaneous emphysema often occurs after the operation; If it is too large, it will cause significant wound pain; postoperative scars and other complications

Moreover, the existing drainage device may fall off or slide and shift during use, which will increase the risk of drainage infection
