Anti-deformation medical tube capable of self-adapting to internal pressure environment of human body

Abstract

The invention discloses an anti-deformation medical tube capable of self-adapting to the internal pressure environment of a human body. The anti-deformation medical tube comprises a heart and a catheter, wherein a femoral artery interface is formed in the femoral artery part of the heart, an aortic valve is arranged on the inner cavity wall of the femoral artery interface, the catheter is inserted in the middle of the aortic valve, a second tube wall sliding head is connected to the outer wall of the catheter in a sliding mode, a middle tube is fixedly connected to the bottom end of the second tube wall sliding head, and a first tube wall sliding head is fixedly connected to the bottom end of the middle tube. According to the anti-deformation medical tube capable of self-adapting to the internal pressure environment of the human body, the catheter is inflated, part of gas is guided into an inner cavity of a cavity rubber tube through a through hole formed in the catheter, the cavity rubber tube in the inner cavity of the cavity rubber tube is pushed to push an expansion frame to move outwards, and the expansion frame is controlled to push a nickel-titanium alloy body to be attached to the inner cavity opening wall of the femoral artery interface.

Description

technical field [0001] The invention relates to the field of medical tubing, in particular to a medical tubing that can adapt to the internal pressure environment of a human body and prevent deformation. Background technique [0002] Medical hose can be divided into two types: external use and internal use. The former is used for various gas and liquid transportation, such as stethoscope hose, infusion hose, etc.; the latter is commonly known as medical rubber catheter, and can be divided into single-lumen tube and multi-lumen tube according to the structure. Single-lumen catheters have only one lumen, and multi-lumen catheters are used for medical and surgical operations. A latex air sac acts as a seal or compress. The rubber catheter is a rubber tube inserted into the body's cavity and blood vessel, and is used to inject medicine or extract body fluid and determine the opening degree of the lumen. Medical hoses require smooth surfaces, non-toxic, odorless, and disinfect...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional medical tubing on the market that can adapt to the pressure environment inside the human body and prevent deformation is applied to improve the valve treatment and replacement technology in the prior art. The existing replacement technology is partly local surgery, and partly artificial The tube body is implanted in the heart at the junction of the tympanic femoral artery and the heart. The valve at the connection site has been in a fluctuating state, resulting in deformation of the implanted medical catheter after being squeezed for a long time, affecting the operation of the heart. The structure is not optimized enough and the design is not reasonable enough
