Embodiment Construction

[0011] As shown in the figure, a closed chest drainage three-way connection tube includes a three-way tube and a screw-in single-way tube 1. The three-way tube includes a drainage tube 2 and a valve tube 3 that are perpendicular to each other. The two ends of the drainage tube 2 The chest cavity and the breast bottle are respectively connected, and the valve tube 3 is provided with a screw-in one-way tube 1 through threaded connection. The screw-in one-way tube 1 can be screwed in or out in the valve tube 3, and the screw-in one-way tube The shape of the bottom end of 1 cooperates with the inner wall of the drainage tube 2. When the screw-in single-way tube 1 is screwed in to the top of the inner wall of the drainage tube 2, the drainage tube can be completely blocked. One end of the protruding valve tube 3 of the screw-in single-way tube 1 is provided with a positive pressure injection cap 4, and the positive pressure injection cap 4 is provided with a drug injection port, and...

Abstract

The invention relates to a thoracic closed drainage three-way connecting tube, which comprises a three-way tube and a screw-in one-way tube, wherein the three-way tube comprises a drainage tube and a valve tube which are perpendicular to each other; two ends of the drainage tube are respectively connected with a thoracic cavity and a chest bottle; the screw-in one-way tube is in threaded connection in the valve tube; one end of the screw-in one-way tube extending out of the valve tube is provided with a positive pressure injection cap; and a medicine guide tube is arranged in the screw-in one-way tube and is communicated with a medicine injection port of the positive pressure injection cap and a medicine outlet on the side wall of the bottom of the screw-in one-way tube. The thoracic closed drainage three-way connecting tube is simple in structure, can conveniently and quickly control the drainage of a thoracic cavity drainage tube and thoracic infusion treatment, eliminates potential safety hazards to the patient and avoids unnecessary injury.

Description

technical field [0001] The invention relates to a medical device, in particular to a three-way connection tube for chest closed drainage. Background technique [0002] Clinically, for patients after thoracotomy, closed chest drainage tubes are routinely indwelled after surgery, especially for patients with lung tumors and pleural tumors, often complicated by pleural effusion in the late stage, and closed chest drainage tubes need to be indwelled for special needs after surgery, such as : Pneumonectomy patients need to open or close the chest tube according to the condition, and patients with advanced pleural cavity perfusion chemotherapy need to clamp the chest drainage or infuse drugs multiple times. Repeated folding of the chest tube or thoracentesis may leave potential safety hazards. or cause injury to the patient. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems and provide a closed chest drai...
