Abstract

The utility model discloses a disposable safe infusion apparatus, which includes a hopper, a dropper and a drain pipe; the disposable safe infusion apparatus is characterized by including a gear shape plastic floating plug and a flexible latex annular cap; the gear shape plastic (or other material) floating plug is arranged in the hopper; and the flexible latex annular cap is arranged in the opening of the drain pipe. The disposable safe infusion apparatus is characterized in that the gear shape plastic (or other material) floating plug is arranged in the hopper of the disposable safe infusion apparatus; the flexible latex annular cap is embedded into the gear shape plastic (or other material) floating plug; when the infusion is almost completed, the floating plug descends with the liquid surface; under the atmosphere pressure and dead-weight pressure of the floating plug, the opening of a drain pipe is plugged by the flexible latex annular cap to stop air to enter a infusion pipeline, thereby preventing the bad influences possibly occurred to patients caused by that the air enters the vein of human bodies, and achieving the goal of safe infusion. Meanwhile, an auto-closing system after the completion of infusion can release the patients and nursing personnel from tensely paying attention to whether the infusion is completed or not and paying attention to pull out the needle in time, and ease the working pressure of the nursing personnel.

Description

Disposable transfusion device safe in utilization

Technical field

This utility model relates to medicine and hygiene fields, is for clinical when the patient is carried out venous transfusion, and when transfusion was nearly finished, shutoff dropping funnel liquid outlet made infusion pipeline liquid stop to flow automatically, prevents the intravital disposable full liquid device safe in utilization of air admission patient.

Background technology

At present at medicine and hygiene fields, be extensive use of disposable infusion set the patient carried out venous transfusion, have intravenously administrable easy to operate, improve curative effect, disposable use, prevent the positive role of cross infection.Yet common disposable infusion set is not owing to possess automatic closing organ, and when failing in time to pull out pin in case transfusion finishes, air just enters into patient's intravenous in the pipeline, can cause the blood coagulation thromboembolism, threat to life when serious.Owing to this kind reason, whether patient and medical personnel must pay close attention to transfusion constantly and finish simultaneously, so that in time pull out pin, bring nervous pressure for patient and medical personnel.

Summary of the invention

In order to prevent the appearance of above situation, the purpose of this utility model provides a kind of disposable transfusion device safe in utilization, on the basis of common disposable infusion set, its dropping funnel built-in a kind of can be at transfusion automatic shutoff infusion unit titrimeter liquid outlet when nearly finishing, make the medicinal liquid in the infusion pipeline of liquid outlet lower end stop to flow, thereby end is infused automatically, reaches to prevent the intravital safe infusion utensil of air admission patient.

The technical solution of the utility model is: disposable transfusion device safe in utilization, it comprises dropping funnel, dropper and drain pipe, it is characterized in that: it also comprises gear-like plastics (or other material) floating plug and flexible latex ring medicated cap, gear-like plastics floating plug is positioned at dropping funnel, and flexible latex ring medicated cap is placed on the mouth of pipe of drain pipe.

Aforesaid disposable transfusion device safe in utilization is characterized in that: be provided with in the dropping funnel and only rise bank, gear-like plastics floating plug is only rising between the mouth of pipe of bank and drain pipe.

Specific practice is, on the basis of common disposable infusion set, places a gear-like plastics floating plug in its dropping funnel, and floating plug seals with liquid outlet and sentences the sealing ring medicated cap that a flexible medical latex is made.During transfusion, liquid flows into dropping funnel from the space of gear-like floating plug, and floating plug rises under the buoyancy of liquid effect, automatically open liquid outlet, realize infusion process, when infusing approaching finishing, floating plug is along with liquid level descends, when floating plug sealing ring medicated cap contacts with liquid outlet, under atmospheric pressure and floating plug gravity pressure, flexible latex sealing ring medicated cap just tightly blocks liquid outlet, makes air not enter into transfusion catheter under the liquid outlet, thereby prevent the air admission human body, realized safe infusion.

The specific embodiment

The explanation of labelling among Fig. 1: dropping funnel 1, dropper 2, only rise bank 3, gear-like plastics floating plug 4, flexible latex ring medicated cap 5, drain pipe 6.

Below in conjunction with drawings and Examples this utility model is further specified.

As shown in Figure 1, the dropping funnel safety of disposable transfusion device safe in utilization comprises from closed system: dropping funnel 1, dropper 2, only rise bank 3, gear-like plastics floating plug 4, flexible latex ring medicated cap 5, drain pipe 6.

Disposable transfusion device safe in utilization of the present utility model, it comprises dropping funnel 1, dropper 2 and drain pipe 6, it is characterized in that: it also comprises gear-like plastics (or other material) floating plug 4 and flexible latex ring medicated cap 5, gear-like plastics floating plug 4 is positioned at dropping funnel 1, and flexible latex ring medicated cap 5 is placed on the mouth of pipe of drain pipe 6.

The transfusion device disposable safe in utilization of present embodiment is characterized in that: be provided with in the dropping funnel 1 and only rise bank 3, gear-like plastics floating plug 4 is between the mouth of pipe that only rises bank 3 and drain pipe 6.

When carrying out the clinical vein transfusion, transfusion device is communicated with medicinal liquid, medicinal liquid splashes in the dropping funnel 1 by dropper 2 through dropping funnel upper end conduit, injection along with medicinal liquid, liquid level in the dropping funnel 1 rises, then gear-like plastics floating plug 4 is because the density of its plastic material that adopts is light than medicinal liquid, then it can be along with liquid level rises, under buoyancy function, float, automatically opened the liquid outlet of drain pipe 6, medicinal liquid will flow in the infusion pipeline by drain pipe and go, thereby realizes the infusion process of normal operating state.When transfusion is nearly finished, the medicinal liquid liquid level descends in dropping funnel, gear-like plastics floating plug 4 descends and descends along with liquid level, cover the liquid outlet of drain pipe 6 until its embedded flexible latex ring medicated cap 4, this moment, dropping funnel internal tooth colyliform plastics floating plug 4 upper ends did not have medicinal liquid, gear-like plastics floating plug 4 is just on the pressure of atmospheric pressure and deadweight, extruding flexible latex ring medicated cap 5, block liquid outlet firmly, make air not enter into the infusion pipeline of liquid outlet lower end, thereby prevented that air admission from patient's body, preventing the generation of fortuitous event.

In addition, too high in order to prevent the position that gear-like plastics floating plug 4 has liquid level to rise, have influence on the situation of observing the dropper drop and take place, this utility model establishes in dropping funnel 1 that a restriction floating plug rises only rises bank 3, makes floating plug be in suitable position all the time.

Fig. 2 is the view of gear-like plastics floating plug, its six teeth keep its center in dropping funnel, and formation space, medicinal liquid is flowed downward by floating plug, floating plug has certain thickness, prevents that floating plug from stirring in the dropping funnel again, and floating plug is more smaller than dropping funnel intracavity diameter, it can be moved up and down in dropping funnel, play float, fall, the effect of shutoff.
