Problems solved by technology

However, in actual use, because the blood vessels are non-linear and often curved, the catheter is prone to discount and blockage, which will have a certain impact on the treatment of patients and even endanger the safety of patients.

Embodiment Construction

[0014] refer to figure 1 , figure 2 , figure 1 , figure 2 It is a structural schematic diagram of a specific embodiment of the present invention. As shown in the figure, the anti-bending central venous catheter includes a catheter body, and the catheter body includes a main catheter 10, a branch catheter 92, and a junction between the main catheter 10 and the branch catheter 92. The catheter connection seat 90, the end of the branch catheter 92 is provided with a connector connected to the syringe, and the number of the branch catheter 92 is determined by the type of simultaneous infusion, generally 1 to 3.

[0015] The catheter body 1 is made of a plastic material with shape memory such as medical silicone material, the winding sleeve 3 is formed by stacked spiral winding wires, and the core wire 2 is made of a shape memory material such as nickel-titanium alloy, so that the core wire 2 can still maintain a better original state after multiple bendings, reduce the resist...

Abstract

The invention discloses a folding-preventing central venous catheter which comprises a catheter body. The catheter body comprises a main catheter, at least one branch catheter and a catheter connecting seat located between the main catheter and the branch catheters. The main catheter comprises a body and a guide wire in the body, wherein the guide wire includes a core wire and a winding sleeve, the body is made of plastic materials with shape memory, the winding sleeve is formed by stacked spiral winding wires, and the core wire is made of shape memory materials. By the arrangement, the core wire can keep good original state after being bent for several times, the catheter can keep communicated under folding conditions by the spiral winding sleeve, and medical accidents are prevented.

Description

technical field [0001] The invention relates to an anti-bending central venous catheter used in clinical medicine. Background technique [0002] A central venous catheter (CVC) is a type of endovascular tube placed in a large vein. Its main purpose: to measure central venous pressure (CVP), to assess circulatory physiological parameters, and to estimate the amount of body fluid. Because of the purpose of measuring CVP, CVP is often used as a false name for CVC in Taiwanese hospitals; large and rapid intravenous infusions often appear in operations with a large amount of blood loss, or to maintain blood pressure during emergency treatment; long-term parenteral nutrition, long-term Antibiotic injections and long-term painkiller injections should be administered; for drugs that are more irritating to peripheral veins (small veins), they should be injected through a central venous catheter instead. For example: Amiodarone, etc.; pipeline for hemodialysis, such as plasma excha...
