Three-way catheter joint for preventing backflow

Abstract

The invention discloses a three-way catheter joint for preventing backflow, and relates to a medical appliance, which includes a T-shaped joint body, and the joint body is respectively provided with a catheter interface, a urine bag connection interface and a sampling interface. ; The catheter interface gradually becomes larger along the flow direction, and the catheter interface is provided with a fixed ring and a ball, and the ball is located at the entrance side of the catheter interface, and a ball is provided between the ball and the fixed ring Compression spring; the outer surface of the catheter interface is provided with hemp lines; the joint body is also provided with a movable plug-in, and the end of the plug-in is located in the sampling interface, and the beginning of the plug-in passes through the joint body to the outside; A through hole connecting the interface of the urinary catheter and the interface of the urine bag is opened on the plug-in; an inclined notch is arranged at the end of the plug-in, and the notch is located on the side of the interface of the urinary catheter. The invention has the advantages of simple structure, convenient sampling, good sealing performance and effective prevention of leakage and backflow of urine.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a three-way anti-reflux catheter joint. Background technique [0002] At present, when nursing patients in the Department of Nephrology after surgery, due to the inconvenient movement of the patient, the urine in the patient's body needs to be discharged through a catheter, but the doctor will sample the patient's urine every day during the entire treatment process. Therefore doctors generally directly sample from the urine bag, and this sampling method has the following disadvantages; Therefore, it will affect the test results; 2. When taking a urine sample with a test tube, the urine will be in contact with the air for a long time, so it will be polluted by the germs in the air, thereby affecting the test results. Dropping on the ground pollutes the environment in the ward, and the second is that the urine is easy to splash during the inspection process; 3. When the patient is not paying...

Dropping on the ground pollutes the environment in the ward, and the second is that the urine is easy to splash during the inspection process; 3. When the patient is not paying attention, the urine in the urine bag is easy to flow back into the catheter, causing the patient's secondary infection
