Abstract

The utility model discloses an improved liquid infusion apparatus for various closed type liquid infusion. The liquid infusion apparatus is provided with a Monfy dripping pipe and the Monfy dripping pipe is composed of a liquid infusion pipe and an air charging needle. The apparatus through the speed of generating air bubbles in a medicine bottle or purification bottle observes the liquid infusion speed. The utility model has the advantages of convenient operation, simple manufacturing process, low cost and high safety.

Description

Closed infuser

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of improved transfusion device.

Before the utility model proposes, transfusion device of the prior art all is made up of luxuriant Fei Shi dropper, tube for transfusion, air inlet needle etc., wherein luxuriant Fei Shi dropper is its most important part, the speed of transfusion is to observe from the speed of this pipe generation drop, so domestic and international any type of transfusion device all possesses luxuriant Fei Shi dropper at present, but the transfusion device with this dropper must be got rid of in use from dropper and enters gas the tube for transfusion, operates work cumbersome even that influence gives emergency treatment to a patient.In addition, owing to the reasons such as complex manufacturing of luxuriant Fei Shi dropper make the cost of transfusion device higher, impel people to reuse and often to cause infusion reaction and cross infection with the transfusion device of abandoning.

Task of the present utility model provide a kind of easy to operate, technology is simple, the cheap transfusion device that helps promoting disposable.

Realize that task of the present utility model is by following approach: in enclosed infusion process, medicinal liquid output makes the interior negative-pressure gas that produces of medicine bottle just go into medicine bottle through air inlet needle, the volume of controlling each bubble is equivalent to the volume of each drop in the luxuriant Fei Shi dropper, the speed that then produces bubble in medicine bottle or the purification bottle is consistent with the speed of generation drop in the luxuriant Fei Shi dropper, this transfusion device that has omitted luxuriant Fei Shi dropper can not produce bubble in tube for transfusion, the comparable existing transfusion device of easy to operate, simple in structure, price is cheap more than 60 percent.

Accompanying drawing is two examples of the present utility model.

Accompanying drawing 1 is the sketch map of this utility model in infusion set.(1) is tube for transfusion among the figure, and (2) are transfusion needle, and (3) penetrate needle stand for the anti-multiple abscess of medium that prevents in the tee T, and (4) are entry needle (or scalp acupuncture), and (5) are intermediate plate, and (6) are air inlet needle, and (7) are medicine bottle.

One end of tube for transfusion (1) and transfusion needle (2) join, and the other end matches with entry needle (or scalp acupuncture) (4) by tee T, are equipped with to prevent that the anti-multiple abscess of medium from penetrating needle stand (3) on tee T.

Accompanying drawing 2 is that this utility model cooperates the sketch map of gas purification bottle in transfusion.(8) are the gas purification bottle among the figure.(9) be the progress air tube.

With Fig. 1 is example, and medicinal liquid behind the transfusion needle insertion medicine bottle is flowed out through entry needle rapidly, and be injectable this moment.According to the needs of transfusion speed, utilize intermediate plate to regulate a speed (every milliliter of medicinal liquid is equivalent to 15～18 bubbles) that produces bubble in medicine bottle or the purification bottle.

With Fig. 2 is example, if medicinal liquid opaque (as blood transfusion), then the device of map interlinking 2 will be equipped with the elongated air inlet needle of air cleaning bottle graft of 75% ethanol, observes the speed that produces bubble from purify bottle.

The utility model has the following advantages than the infusion set that uses at present: (1) is easy to operate, Without exhaust; (2) self-closed after the medicine feeding hole dosing; (3) simple, the economical with materials of technology, fall Low cost is conducive to promote the disposable transfusion device to reduce infusion reaction and cross-infection.

The Open system method has been closed the formula transfusion and has replaced, and the utility model is applicable to all Closed transfusion.

Claims

A kind of transfusion device mainly is made up of tube for transfusion (1) and air inlet needle (6), it is characterized in that transfusion device does not adopt luxuriant Fei Shi dropper.One end of tube for transfusion is connected with transfusion needle (2); The tee T of the other end combines with entry needle (4); Dosing hole in the tee T is one and prevents that the anti-multiple abscess of medium from penetrating needle stand.
