Description

Drainage tube connector fixing device

technical field

The utility model relates to the technical field of medical devices, in particular to a drainage pipe joint fixing device.

Background technique

Drainage tube is a medical device used for clinical surgical drainage to guide pus, blood, and liquid accumulated between human tissues or body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used clinically, some are used for catheterization, some are used for wounds, and they are used in the chest cavity, brain cavity, gastrointestinal tract, and biliary tract. The purpose of surgical drainage is to guide the pus, blood, and fluid accumulated between human tissues or body cavities to the outside of the body, so as to prevent postoperative infection and affect wound healing.

The drainage tube is generally made of materials such as silicone rubber or polyurethane. When in use, one end of the catheter is inserted into the body or the drainage site of the wound, and the other end can be connected to other external devices such as drainage tubes outside the body, and the catheter can be drained outside the body through pressure such as internal pressure, gravity, or negative pressure suction.

For urology patients, an external catheter is generally placed after surgery, that is, the first end of the catheter is inserted into the bladder, and the end of the catheter is inserted into the drainage bag. After a period of treatment, urology patients can go to the ground in the early stage of recovery For self-walking exercises, there will often be leakage at the junction of the end of the catheter and the drainage bag during the walking exercise, and more seriously, the end of the catheter will be separated from the drainage bag. , resulting in pulling and swinging between the end of the catheter and the drainage bag, making it impossible to seal tightly. In the prior art, in view of the above situation, medical staff generally use sticky cloth to fix and seal the joint between the two, although it plays a certain role. Effect But when changing the urine bag for the patient, it is necessary to tear off the sticky cloth and then replace it. However, during the replacement process, a certain amount of glue will adhere to the joint of the drainage tube and the drainage bag, which increases some inconvenience. At the same time, using this method Repeated replacement is also relatively troublesome, which indirectly increases the workload of medical staff.

Detailed ways

Referring to the accompanying drawings, the drainage pipe joint fixing device includes a first clamping assembly 1, a second clamping assembly 2, an inner connecting pipe 3 and a nitrile end face sealing ring 4;

A nitrile end face sealing ring 4 is installed between the first clamping assembly 1 and the second clamping assembly 2, and the connection between the first clamping assembly 1 and the second clamping assembly 2 is threaded, and the inner connecting pipe 3 is arranged on the first clamping assembly. Inside the tight assembly 1 and the second clamp assembly 2;

The first clamping assembly 1 includes a first main body 10, a rotary pressing member 11, a conical sealing head 12, a flexible sealing ring 13, a sealing pad 14 and an extrusion ring 15;

The outer wall of the first main body 10 is provided with a threaded area 102, and the rotating pressing part 11 is connected to the threaded area 102. The side of the rotating pressing part 11 away from the first main body 10 is provided with an annular claw 110, and the inside of the first main body 10 is provided with a Insert the first drainage tube 5 into the jack, and the outside of the jack is provided with an extrusion cavity 100, and the extrusion cavity 100 is sequentially provided with a gasket block 14, a flexible sealing ring 13 and an extrusion ring 15 from the inside to the outside. The ring 15 is provided with a tapered extrusion groove 150 on the side away from the flexible sealing ring 13, and the outer wall of the conical sealing head 12 is provided with a limit card slot 120. The circumferential movement of 110 can drive the conical sealing head 12 to move axially. The head end of the conical sealing head 12 is provided with multiple sets of deformation grooves 121, and the conical sealing head 12 can extend to the inside of the conical extrusion groove 150 to displace the first Constrained by the drainage tube 5; the end of the first drainage tube 5 extends into the socket between the inner wall of the first main body 10 and the outer wall of the inner connection tube 3;
