Abstract
The utility model discloses a kind of automatic blocking-up type blood return prevention Murphy pipe, comprise Murphy tube body, partition is provided with in the tube chamber of Murphy tube body, partition is provided with through hole, elastic rubber pipe is provided with above through hole, one end of elastic rubber pipe is fixed on partition, and the other end is provided with ball float, and the tube wall of elastic rubber pipe is provided with otch.This utility model can prevent blood back by automatic stop liquid, decreases the burden of patient and medical personnel, has and be skillfully constructed, and structure is simple, easy to use, the features such as cost of manufacture is low.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of automatic blocking-up type blood return prevention Murphy pipe.
Background technology
Tradition Murphy pipe can observe the speed of drop, but infusion bottle is once drip off, liquid level will decline, and once drop to below Murphy pipe very lower position, negative pressure is formed and causes needle tubing blood back, there are the problems such as blood contamination, blood coagulation, therefore need patient or nursing staff often to observe infusion bottle clinically, once transfusion is close to complete, nurse needs to carry out in time changing dressings or pulling out pin, in case return blood, thus add the burden of patient and medical personnel.
Some blood return prevention Murphy pipe improved, be film material, have during liquid and can permeate, no liquid produces sealing function makes transfusion stop, this kind of film material construction is higher, complex structure, and a lot of macromole liquid, compound ion liquid can be produced uncertain chemical affect, thus be restricted on Clinical practice.
Summary of the invention
The purpose of this utility model is to provide one can block transfusion automatically, the Murphy pipe of anti-return blood.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of automatic blocking-up type blood return prevention Murphy pipe, comprise Murphy tube body, partition is provided with in the tube chamber of Murphy tube body, the tube chamber of Murphy tube body is separated into upper and lower two parts by described partition, described partition is provided with through hole, and be provided with elastic rubber pipe above described through hole, one end of described elastic rubber pipe is fixed on partition, the other end is provided with ball float, and the tube wall of described elastic rubber pipe is provided with otch.
Described plastic sheet is positioned at below the tube chamber of Murphy tube body.
Described otch is thread-shaped.
Described ball float is hollow plastic ball.
During normal infusion, there is more medicinal liquid in tube chamber, elastic rubber pipe, at the effect float downward of medicinal liquid buoyancy, upwards lifts by ball float, and the otch on tube wall opens, through inside and outside rubber tube, and transfusion is carried out smoothly; Along with medicine bottle liquid drips off, during Murphy pipe upper half-space no liquid, elastic rubber pipe is not lifted by ball float, cut closure on tube wall, not through inside and outside rubber tube, block transfusion and carry out, it is no longer descending that liquid level is parked in the Murphy pipe lower half-space, form malleation and prevent blood back, air column can not be formed.This utility model can prevent blood back by automatic stop liquid, decreases the burden of patient and medical personnel, has and be skillfully constructed, and structure is simple, easy to use, the features such as cost of manufacture is low.
