Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of transfusion device that has blood back flowing device.
Background technology
When the patient is infused, whether penetrating blood vessel accurately for syringe needle at present, all is that the experience by medical personnel is judged, and the result that neither one can come direct representation to come out to penetrate by device.
The utility model content
In view of this, main purpose of the present utility model be to provide a kind of simple in structure, can show the situation that syringe needle penetrates blood vessel very intuitively, to remedy the deficiencies in the prior art.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of transfusion device that has blood back flowing device, comprise syringe needle, drain pipe, described drain pipe is connected with syringe needle, also include blood back flowing device, described blood back flowing device is by the blood back cavity, inlet, liquid outlet and rubber gallbladder constitute, described blood back cavity is made by transparent material, described inlet and liquid outlet are arranged on the blood back cavity, described rubber gallbladder is arranged in the blood back cavity, rubber gallbladder opening and blood back cavity are tightly connected, and rubber gallbladder inside is connected with blood back cavity is external by rubber gallbladder opening, and described drain pipe is connected with liquid outlet.
Described blood back cavity is a column type, and described rubber gallbladder opening is fixed on the upper surface or lower surface of blood back cavity.
When the patient is infused, the medicinal liquid of importing links to each other with inlet through feed tube, arrive syringe needle by the blood back cavity, when veins beneath the skin is carried out acupuncture, tie feed tube, in the blood back cavity during without any reaction, illustrate that medical personnel do not sting medium vessels, need carry out acupuncture work again, in the time of in acupuncture is pricked, blood pressure in the human vas is higher than the intravital pressure of blood back cavity, rubber gallbladder pressed volume is dwindled, and people can see very clearly that blood is back in the blood back cavity, illustrate that acupuncture penetrates in the blood vessel, open feed tube this moment, finishes the acupuncture work of transfusion.
Beneficial effect after the employing technique scheme is: this utility model has the transfusion device of blood back flowing device, by the technical program, can see the result of transfusion operation very intuitively, make transfusion work simple, intuitive more, improve the safety of work greatly, reduced operation easier.
