Abstract
The utility model discloses a self-closing transfusion system, which is provided with a catheter (1) and a liquid storing pipe (2), wherein a floating ball (3) having a diameter which is larger than that of the catheter (1) is arranged in the liquid storing pipe (2). The catheter can be closed automatically after physic liquor is transfused, the phenomenon of back blood flow or air admission in veins can be efficiently prevented, patients' worry is eliminated, and the working strength of nursing staff is reduced. The utility model having the advantages of simple structure, low cost, etc. can be widely used for clinical treatment.
Description
Technical field:
This utility model relates to a kind of intravenous transfusion device that is applied to medical field, especially a kind of self-closing transfusion device.
Background technology:
At present, the intravenous transfusion device that is applied to medical field is made of liquid storage pipe, speed regulator and the venoclysis needle of inserting bottle (bag) pin, a conduit, be connected between the conduit.This kind intravenous transfusion device does not have safety protection function; must notify medical personnel immediately after medicinal liquid is totally lost, in time pull out syringe needle, otherwise accidents such as blood back or air admission vein will occur; this just needs patient or nursing staff to keep a close eye on the transfusion situation, makes patient or nursing staff feel more nervous.In order to address this problem, there is Crinis Carbonisatus to understand infusion alarm, promptly after medicinal liquid was totally lost, alarm was reported to the police automatically, with the prompting medical personnel.But, because infusion alarm structure more complicated, the maloperation phenomenon is arranged in addition, thus up to the present, infusion alarm can't extensive use clinically.
Summary of the invention:
This utility model is that accidents such as blood back or air admission vein, patient appear in existing in prior technology easily or nursing staff's burden heavily waits technical problem in order to solve, provide a kind of simple in structure, can be at the medicinal liquid back self-closing transfusion device of closes ducts automatically of being totally lost.
Technical solution of the present utility model is: a kind of self-closing transfusion device, conduit 1 and liquid storage pipe 2 are arranged, and described liquid storage pipe 2 is built-in with the ball float 3 greater than conduit 1 diameter.
This utility model is automatic closes ducts after medicinal liquid is totally lost, and can prevent effectively that blood back or air admission venous phenomenon from taking place, and has removed patient's worry, has reduced nursing staff's working strength.Have simple in structure, low cost and other advantages, but extensive use clinically.
