Abstract

The utility model relates to a disposable V-shaped transfusion device, which is designed according to the principles of air pressure difference and a communicating vessel. Two physic liquor bottles form definite height difference and are connected through a communicating pipe; the transfusion pipes of two bottles of physic liquor form a V-shaped structure, and the transfusion of the other bottle of physic liquor can be automatically started after one bottle of physic liquor is completed. The transfusion of the structure can complete the transfusion of two bottles of physic liquor in one time. Compared with time separating transfusion, the utility model has the advantages of convenient operation and simple structure, improves work efficiency, and reduces pollution opportunity.

Description

Once-used V-shape transfusion system

This utility model belongs to a kind of medical apparatus and instruments, is specifically related to a kind of disposable transfusion device.

In patient's medical treatment and nursing process, often need to import two or more medicinal liquid, and usually these several medicinal liquids can not mix input, or mix back medicinal liquid curative effect and reduce, in this case, in the prior art, generally adopt the gradation transfusion, promptly be totally lost one bottle earlier, then operate another bottle again again, this method is troublesome poeration not only, inefficiency, and increased the chance that the patient pollutes.

The purpose of this utility model provides a kind of new disposable V-arrangement transfusion device, in view of the above two bottle liquid medicines can be on demand before and after disposable being totally lost, be specially adapted to two kinds can not admixing medical solutions the transfusion of transfusion.

This utility model mainly is to utilize the principle of pressure differential and linker to realize.

Below in conjunction with accompanying drawing this utility model is done a detailed explanation.

First bottle (1), second bottle (4) are for being equipped with the infusion bottle of different medicinal liquids, and first bottle (1) is higher than the long above distance of (4) bottles of second bottle, because the existence of difference in height makes both have certain pressure difference: P _First＞P _SecondFirst bottle (1) inserts an air inlet pipe (2), makes it to communicate with atmosphere, and first bottle (1) communicates by a connecting pipe (5) with second bottle (4), and the tube for transfusion (3) of first bottle (1) forms a v-shaped structure with the tube for transfusion (6) of second bottle (4).

During transfusion, enter the ventilation of bobbin head with one earlier, the interior pressure of two medicinal liquid bottles is equated with outside pressure, again air inlet pipe (2) is inserted first bottle (1), and be two of V-arrangement pipe tube for transfusion (3) and tube for transfusion (6) inserts first bottle (1), second bottle (4) respectively, open and control valve (7), export with certain speed at atmospheric pressure effect Carapax et Plastrum Testudinis bottle (1) herb liquid, first bottle (1) is carried when finishing, because the effect of communicating pipe (2), bottle (4) is under the atmospheric pressure effect, and medicinal liquid finishes up to transfusion by the transfusion of second bottle of tube for transfusion (6) beginning.

For making the easier enforcement of this utility model, first bottle (1) can be provided with plastics respectively with second bottle (4) and hang the bottle cover, and both connect together by an elasticity rope yarn.

The bobbin head that enters described in the utility model adopts 7-9 number, No. 12, communicating pipe (2) syringe needle employing.

This utility model compared with prior art has following a few advantage:

(1) two bottle liquid medicine can be on demand before and after input, both be applicable to two bottles of mutual admixing medical solutions of energy, also be applicable to two bottles can not admixing medical solutions transfusion.

(2) because the disposable conveying of finishing two bottle liquid medicines can be saved the labour force, increase work efficiency.

(3) reduce opportunities for contamination, be beneficial to patient health.

(4) avoid in the gradation infusion process, unknownly thereby first bottle of liquid is not totally lost fully or has been totally lost make air admission, improved the drug use rate, reduced unnecessary trouble.

(5) utilize atmospheric pressure and law of connected vessels, simple in structure, easy to operate, and also economical and practical.

Accompanying drawing is this real new structure sketch map.

Embodiment: penicillin and V _B6Liquid is two kinds of medicinal liquids that can not mix use, can make according to disposable V-arrangement transfusion device described in the utility model that two bottle liquid medicines are disposable is totally lost, and is respond well, working stability.

Claims (3)

1, a kind of disposable V-arrangement transfusion device, comprise infusion bottle and tube for transfusion, it is characterized in that: form a difference in height on medicinal liquid first bottle (1) and medicinal liquid second bottle (4) position, and by linking to each other the tube for transfusion (3) of first bottle (1) and the tube for transfusion (6) of second bottle (4) formation one v-shaped structure communicating pipe (5).

2, disposable V-arrangement transfusion device according to claim 1 is characterized in that: first bottle (1) is more than the bottle distance with the difference in height of second bottle (4).

3, disposable V-arrangement transfusion device according to claim 1 and 2 is characterized in that: described first bottle (1), second bottle (4) can be fixing by the plastic bottle cover, and linked to each other by an elasticity rope yarn.
