Embodiment Construction

[0013] refer to figure 1 , figure 1 It is a structural schematic diagram of a specific embodiment of the present invention. As shown in the figure, the anti-pressure pigtail catheter includes a catheter body 1, and is characterized in that: a spring-like support ring 3 is arranged on the inner wall of the catheter body 1, and the The spring-like support ring 3 is made of a rigid material. Preferably, in this embodiment, the spring-like support ring 3 is wound from a medical steel material to improve the strength of its support structure. The catheter tube The body 1 is made of plastic material with shape memory. Preferably, in this embodiment, the catheter body 1 is made of medical silicone material to improve its flexibility and reduce the impact on human blood vessels, ureters, etc. injury, the present invention can provide a certain support force for the tube wall of the catheter body 1 through the spring-like support ring 3, and can still keep the catheter body in a condu...

Abstract

The invention discloses a compressive resistant pigtail conduit. The compressive resistant pigtail conduit comprises a conduit tube body; the internal wall of the conduit tube body is provided with a spring-shaped supporting ring; the spring-shaped supporting ring is made of rigid materials; the conduit tube body is made of shape memory plastic materials. The spring-shaped supporting ring can provide certain supporting force for the tube wall of the conduit tube body, then the conduit tube body can keep a communication state under lateral press, the conduit is effectively prevented from being squeezed to be narrowed down and blocked, and the safety of the conduit is improved.

Description

technical field [0001] The invention relates to an anti-stress pigtail catheter used in clinical medicine. Background technique [0002] Pigtail catheter, named for its curled ends, each end resembling a pig's tail. Due to its stent and internal drainage function, it can relieve temporary obstruction caused by ureteral inflammation and edema, and prevent postoperative wound leakage and ureteral stricture. At the same time, the collection system is not directly connected to the outside world, which can avoid bleeding and infection caused by nephrostomy; because there is no restriction and discomfort of the external drainage tube, the patient can get out of bed early, which is beneficial to postoperative recovery. , as the patient sits down. Actions such as lying down will squeeze the catheter laterally, causing the catheter to be squeezed and narrowed or blocked, which is very dangerous, especially when the patient is sleeping or unconscious, and it is very easy to cause me...
