Problems solved by technology

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 from the external drainage tube, the patient can get out of bed early, which is conducive to postoperative recovery. At that time, the current pigtail Catheters are all straight-through tubes without anti-backflow function, so patients are required not to lie down to prevent urine from backflowing to the kidneys, which may cause kidney poisoning or infection, which has a high risk

Embodiment Construction

[0014] 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-backflow pigtail catheter includes a catheter body 1. In this embodiment, the catheter body 1 is a double-J type pigtail catheter. The double-J type Both ends of the pigtail catheter are provided with J-shaped coils.

[0015] In the present invention, the conduit body 1 is provided with an anti-backflow device. Preferably, the anti-backflow device is a disc type check valve 12, which includes a valve body and a valve disc, wherein the valve disc can be a flexible The valve disc or rigid valve disc, in this embodiment, preferably adopts a flexible valve disc to ensure smooth opening and closing. When the fluid flows from the kidney to the bladder, the valve disc opens due to the pressure of the fluid. When the fluid flows from the bladder to the kidney, the valve disc opens. The valve disc is closed due to the pressure of...

Abstract

The invention discloses a backflow prevention pigtail catheter. A catheter body can be a double J type pigtail catheter or a single J type pigtail catheter; a backflow prevention device is arranged in the catheter body; the backflow prevention device is a valve clack type check valve. According to the backflow prevention pigtail catheter, the valve clack type check valve is used for preventing the urine from flowing back to the kidney effectively, a patient can walk uprightly or lay down for rest, the postoperative recovery of the patient is facilitated, the safety is high, and the popularization value is high.

Description

technical field [0001] The invention relates to an anti-reflux 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 from the external drainage tube, the patient can get out of bed early, which is conducive to postoperative recovery. At that time, the current pigtail Catheters are all straight-through tubes without anti-backflow function, so patients are required not to lie down to prevent urine from backflowing to the kidneys, which may cause kidney poisoning or infection, which has a high ris...
