Abstract

The utility model provides an outer connection reverse-flow-prevention device for a medical drainage pipe. A one-way double movable valve is connected with the inner wall of a medical silicon rubber pipe on one end of the outer connection reverse-flow-prevention device for a medical drainage pipe which is connected with a plastic pipe joint. Anti-slide ripples are arranged on the outer surface of the plastic pipe joint. The utility model has the advantages of simple structure, convenient use, etc.

Description

A kind of medical drainage tube is taken over control recirculation device outward
This utility model relates to medical apparatus and instruments, and the drainage tube that uses in especially a kind of and the clinical position is connected prevents the device that drain liquid backflows.
Drainage is a kind ofly in the clinical position to treat measure timely and effectively, be widely used in each patient's of section such as inside and outside, woman, youngster treatment, drainage tube generally places in body cavity (as breast, intraperitoneal drainage) and hollow organ (as gastrointestinal decompression tube, catheter etc.) and various vomica, the haematoma cavity.Conventional drainage tube stands up in clinical care, during removing patient, easily cause drain liquid to backflow, and causes retrograde infection.In order to make drain unobstructed, prevent to backflow, adopt depression drainage device usually, its weak point is that the excessive drainage lumens wall that forms of negative pressure stops up pore, causes temporary inadequate drainage, and can cause the drainage lumens internal hemorrhage; When negative pressure disappeared, the drain liquid in drainage tube and the drainage bag backflowed rapidly into drainage lumens; In addition, many drains do not allow to use negative pressure, as ventricular drainage etc.In recent years, the relevant expert has done a lot of effort, and unidirectional flap valve backstop or check valve are set on existing drainage system, and its weak point is that range of application is little as the ingredient of concrete drainage system, and complex structure uses inconvenience.
The purpose of this utility model provides a kind of simple in structure, device that drain liquid backflows that prevents of being suitable for each clinical use of section of hospital.
The purpose of this utility model can realize by following measure: the medical grade silicon rubber inside pipe wall that at one end connects joint for plastic tube is connected with unidirectional dual-active lobe.
The purpose of this utility model also can realize by following measure: be provided with anti-skidding ripple at the joint for plastic tube outer surface.
This utility model has designed anti-backflow device according to the unidirectional principle of closing of venous valve, is bivalve shape, and the lobe leaf is borrowed attachment margin and medical grade silicon rubber inside pipe wall shape pouch gap, and the bivalve intersection is the center in the medical grade silicon rubber pipe.When drain liquid forward flowed, two lobes were attached at the medical grade silicon rubber inside pipe wall, and tube chamber is unobstructed.When drain liquid adverse current, two lobe leaves open, and free edge meets in the tube chamber center line, form closed state, stop drain liquid adverse current.Should prevent that recirculation device was simple in structure, can use after pegging graft with other each drainage systems that the character of drain was not had specific (special) requirements, can be applicable to various drains, safe and reliable.
Fig. 1 is that this utility model is worked as the sketch map of drain liquid when forward flowing;
Fig. 2 is this utility model figure between showing when working as the reverse flow of drain liquid;
The 1-joint for plastic tube, 2-medical grade silicon rubber pipe, the unidirectional dual-active lobe of 3-.

Claims (2)

1, a kind of medical drainage tube is taken over control recirculation device outward, it is characterized in that medical grade silicon rubber pipe (2) inwall of end connection joint for plastic tube (1) is connected with unidirectional dual-active lobe (3).
2, a kind of medical drainage tube according to claim 1 is taken over control recirculation device outward, it is characterized in that joint for plastic tube (1) outer surface is provided with anti-skidding ripple.
