Abstract
The utility model relates to a transfusion system, in particular to a medical safe transfusion system. The medical safe transfusion system comprises a Murphy's dropper, a transfusion regulator, a filter and a transfusion tube, wherein the Murphy's dropper is positioned on the upper part of the transfusion system, the filter is positioned on the lower part of the transfusion system, the transfusion regulator is positioned between the Murphy's dropper and the filter and can be vertically adjusted, a ball valve is arranged in the Murphy's dropper, and the ball valve floats in the liquid medicine of the Murphy's dropper. The utility model can prevent the blood from flowing into the tube due to negative pressure after the dripping of the liquid medicine, has simple structure, convenient operation, safe utilization and the like, and can be widely used for vein transfusion and vein injection.
Description
One, technical field:
This utility model relates to a kind of transfusion device, particularly relates to a kind of medical safe transfusion device.
Two, background technology:
At present; medicine in the medical treatment in the infusion bottle is by the intravenous injection to human body of disposable transfusion device, syringe needle; its therapeutic effect is rapid; but the problem of its existence is: after the medicine of infusion bottle drips off; because nursing staff and patient forget the observation infusion bottle through regular meeting; cause blood back, cause patient's pain even cause danger.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and transfusion is provided when providing a kind of medicinal liquid to drip off automatically, prevents the medical safe transfusion device of blood back.
Its technical scheme is: comprise Murphy's dropper, infusion regulator, filter and tube for transfusion, Murphy's dropper is positioned at the top of transfusion device, filter bits is in the bottom of transfusion device, infusion regulator is between Murphy's dropper and filter and can up-down adjustment, be provided with ball valve in the described Murphy's dropper, ball valve floats in the interior medicinal liquid of Murphy's dropper.
The beneficial effects of the utility model are: because the blood back that negative pressure causes has advantages such as simple in structure, easy to operate, safe in utilization, can be widely used in intravenous drip and intravenous injection when having avoided medicinal liquid to drip off.
Four, description of drawings:
Structural representation when accompanying drawing 1 is a normal dropping liquid of the present utility model;
Accompanying drawing 2 is the structural representations after dropping liquid of the present utility model finishes.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1 and 2, the utility model will be further described, its technical scheme is: comprise Murphy's dropper 1, infusion regulator 2, filter 3 and tube for transfusion 4, Murphy's dropper 1 is positioned at the top of transfusion device, filter 3 is positioned at the bottom of transfusion device, infusion regulator 2 is provided with rubber or ball valve made of plastic 5 between Murphy's dropper 1 and filter 3 and can up-down adjustment in the described Murphy's dropper 1, ball valve 5 floats in the medicinal liquid of inner chamber of Murphy's dropper 1.
During normal infusion, ball valve swims on the medicinal liquid in the Murphy's dropper 1, does not influence dropping liquid; When the nursing staff did not find that medicinal liquid is about to drip off, ball valve can fall to being stuck in the lower end outlet of Murphy's dropper automatically, and it is descending along tube for transfusion to avoid medicinal liquid to continue, and has prevented because the blood back that negative pressure causes has been avoided medical danger.
