AI Technical Summary
Traditional catheters are prone to thrombosis when not in a therapeutic state, and blood residue at the catheter tip can form a blood clot, increasing the risk of infection. In addition, blood can easily accumulate at the catheter opening, forming a thrombus.
A thrombosis-preventing central venous catheter was designed, comprising a plug and a side hole. The plug is at an angle of 4% to 8%, and the side hole is 4mm to 8mm in length. It prevents thrombosis and drug residue. It is made of silicone to improve lubrication and has X-ray imaging capability.
It effectively prevents thrombosis, reduces the risk of infection, and avoids drug residue through the design of the plug and side holes, thus improving the safety of catheter use.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to medical catheter technical field, concretely is a kind of antithrombotic central venous catheter. BACKGROUND
[0002] Blood access is the "lifeline" of maintenance hemodialysis patients, with the extension of dialysis time, blood vessel depletion, patients cannot establish autologous arteriovenous fistula and transplant vascular fistula, the use of central venous catheter is inevitable.
[0003] Disadvantages of prior art:
[0004] At present, the traditional catheter in non-treatment state, catheter long-term retention is prone to thrombosis to cause blood flow to drop, and blood also remains in catheter head thread place and forms scab, increases catheter infection probability, existing catheter is directly open type, without plug, blood is easy to accumulate in open place and form thrombus. UTILITY MODEL CONTENT
[0005] The utility model aims at providing a kind of antithrombotic central venous catheter to solve the problems raised in the above background.
[0006] To achieve the above object, the utility model provides the following technical scheme: an antithrombotic central venous catheter, including pipe body, the pipe body is provided with antithrombotic assembly, and the antithrombotic assembly includes:
[0007] Plug, the plug is set to one end of the pipe body, and the plug is 4%~8% angle;
[0008] Side hole, the side hole is set to the pipe body close to the plug.
[0009] Preferably, the pipe body is selected as silica gel material.
[0010] Preferably, the length of the side hole is set to 4mm~8mm.
[0011] Compared with prior art, the utility model has the beneficial effects that:
[0012] The antithrombotic central venous catheter is provided with antithrombotic assembly, antithrombotic assembly includes plug and side hole, plug is installed in one end of pipe body, angle is set to 4%~8%, plug has taper and can be conveniently pushed during catheterization, compared with plug, it is not easy to form thrombus, side hole is set on pipe body close to plug, side hole will not form dead angle at the connection of pipe body and plug, can effectively avoid drug liquid residue and thrombus formation, reduce infection probability.
