Abstract

The utility model provides a self-closing safety infusion device for intravenous drip infusion and belongs to the field of medical devices. The utility model aims to provide a self-closing safety infusion device for intravenous drip infusion, which has a low manufacturing cost and can automatically close an infusion pipe after the drip infusion is completed. According to the self-closing safety infusion device, the upper end of a dropper is connected with a solution feed pipe, a solution guide pipe is mounted to a solution outlet pipe which is arranged at the lower end of the dropper in a sealing manner, a T-shaped rod is inserted into the solution outlet pipe, a floator is mounted to the end of the T-shaped rod inserted into the dropper, a cross bar is arranged at the lower end of the T-shaped rod, and the cross bar is clamped at the mouth of the solution outlet pipe. The self-closing safety infusion device has a simple structure, and the floator declines with the flow of an injection solution. When the injection solution runs out, the floator automatically seals the upper end of the solution outlet pipe to prevent the air from entering the solution outlet pipe.

Description

The safe fixed point infusion set of self-closing

Technical field

This utility model belongs to medical instruments field.

Background technology

Medical institutions often will carry out fluid infusion for patient when the treatment disease, when carrying out drop, need personnel to monitor, prevent after medicinal liquid is totally lost to patient's cause danger, for this reason, some designer installs electronic alarm at tube for transfusion, but its cost is higher, for present disposable transfusion device, cause very large waste.

Summary of the invention

It is low that the purpose of this utility model provides a kind of cost, behind infusion-completed, with the safe fixed point infusion set of the self-closing of tube for transfusion autoshutdown.

Dropping funnel of the present utility model upper end connects feed tube, drain pipe in the dropping funnel lower end is sealed and installed with the flow liquid conduit, is inserted with T shape bar in drain pipe inside, and it is cursory that the end that T shape bar is deep into dropping funnel inside is equipped with, T shape bar lower end is cross bar, and cross bar is stuck in the mouth place of drain pipe.

This utility model is simple in structure, cursoryly descends along with flowing of medicinal liquid, after medicinal liquid is finished using, cursoryly automatically the drain pipe upper end is sealed, and has prevented entering of air.

Description of drawings

Fig. 1 is this utility model structural representation;

Fig. 2 is that this utility model Figure 1A is to the Local map view.

The specific embodiment

Dropping funnel of the present utility model 2 upper ends connect feed tube 1, drain pipe 4 in dropping funnel 2 lower ends is sealed and installed with flow liquid conduit 6, is inserted with T shape bar 7 in drain pipe 4 inside, and the end that T shape bar 7 is deep into dropping funnel 2 inside is equipped with cursory 3, T shape bar 7 lower ends are cross bars 5, and cross bar 5 is stuck in the mouth place of drain pipe 4.

This utility model is because large pipe box tubule has the cross section in bassoon, so on the horizontal tangent plane that is stuck in tubule of the cross bar below cursory, make the cursory come-up that is unlikely to enter dropping funnel inside, plays and stablizes cursory effect.

Because transfusion face descends, cursoryly descend thereupon, cursoryly be lower than transfusion face, so at transfusion face during near the fluid mouth of pipe, cursoryly just drain pipe is blocked, prevented entering of air, can not bring hidden danger to the patient like this, thereby play a protective role.

Claims

1. safe fixed point infusion set of self-closing, dropping funnel (2) upper end connects feed tube (1), it is characterized in that: the drain pipe (4) in dropping funnel (2) lower end is sealed and installed with flow liquid conduit (6), be inserted with T shape bar (7) in drain pipe (4) inside, T shape bar (7) is deep into the inner end of dropping funnel (2) cursory (3) is installed, T shape bar (7) lower end is cross bar (5), and cross bar (5) is stuck in the mouth place of drain pipe (4).
