Abstract

The utility model provides a disposable safety infusion device with precision automatic liquid stopping function, which is used for venous transfusion in the field of medicine clinics. The infusion device comprises an insertion needle, a hose, a safety dropper (proposed by the applicant), a flow controller, a medicinal solution filter and an intravenous infusion needle, wherein a semi-spherical funnel is arranged at the bottom of the safety dropper (see the attached figure), a smooth medicinal solution passage is arranged at the lower part of the funnel, and a latex ball float is placed inside the safety dropper. The ball float moves up and down inside the safety dropper, so that the ball float is embedded with the semi-spherical funnel before the medicinal solution flows in, and floats upwards by means of buoyancy of the medicinal solution after the medicinal solution flows in. After the infusion is completed, the ball float moves to seal the bottom opening of the funnel along with the drop of the medicinal liquid level, so as to seal the medicinal liquid passage, thereby preventing the air from entering the lower part of the dropper and ensuring safe infusion.

Description

Disposable precision is ended the liquid safe transfusion system automatically
Affiliated technical field
This utility model is the accurate liquid safe transfusion system that ends automatically of disposable use, and this transfusion device is applicable to the venous transfusion in the clinical medicine field.
Background technology
At present, intravenous transfusion device commonly used in the clinical medicine field is by needle for inserting bottle, flexible pipe, and Murphy type burette, flow regulator, liquid medicine filter, venoclysis needle is formed.In infusion process, need the person of accompanying and attending to pay close attention to the liquid level of medicinal liquid, otherwise, reduce to the Murphy type burette lower end when the liquid level of medicinal liquid, gas enters the lower end, splashes into blood vessel as gas and easily causes air embolism, threat to life safety.
Summary of the invention
In order to reach safe infusion, alleviate nursing staff's operating pressure, this utility model provides a kind of disposable use the accurate liquid safe transfusion system that ends automatically.
The technical scheme that its technical problem that solves this utility model adopts is; Novel precise ends the liquid safe transfusion system automatically by needle for inserting bottle, flexible pipe, the Zhu Shi safety pipet, flow regulator, liquid medicine filter, venoclysis needle is formed, wherein Zhu Shi safety pipet bottom design is a hemispheroid funnel, and the dropping funnel lower curtate has a bright and clean medicine liquid channel, has put into a latex ball float in the safety pipet, ball float can move up and down in safety pipet, comes preceding ball float of medicine and hemispheroid funnel to inlay.In use, ball float floats by means of medicinal liquid, and medicinal liquid then can be input to the fluid dropper, and when medicinal liquid dripped off, ball float dropped to spherical hopper Di Kou position with the medicinal liquid liquid level and seals, and the sealing infusion channel is advanced less than the dropper bottom air and realized safe infusion.
The beneficial effects of the utility model are, drip off at medicinal liquid and need change bottle or when finishing, ball float drops to mouth at the bottom of the spherical hopper with the medicinal liquid liquid level, ball float and hemispheroid funnel are inlayed once more, infusion channel is closed, the dropper bottom is owing to the effect of negative pressure keeps liquid level, and air can not enter, thereby has realized safe infusion.

The specific embodiment
In Fig. 1, novel precise ends the liquid safe transfusion system automatically by needle for inserting bottle, flexible pipe, and the Zhu Shi safety pipet, flow regulator, liquid medicine filter, venoclysis needle is formed.
In Fig. 2, Zhu Shi safety pipet bottom design is a hemispheroid funnel, and the dropping funnel lower curtate has a bright and clean medicine liquid channel, has put into a latex ball float in the safety pipet, and ball float can move up and down in safety pipet, comes preceding ball float of medicine and hemispheroid funnel to inlay.
In the embodiment shown in fig. 3, in the use, ball float floats by means of medicinal liquid, and dropping funnel lower curtate medicine liquid channel is open, and medicinal liquid is input in the fluid dropper, is input to human body through venoclysis needle.When medicinal liquid dripped off, ball float dropped to spherical hopper Di Kou position with the medicinal liquid liquid level infusion channel is sealed, and has realized safe infusion thereby air is advanced less than the dropper bottom.

Claims (2)
