Abstract
The utility model relates to a medical treatment equipment technology field, in particular to a transfusion device preventing blood returning developed on the basis of existing transfusion device technique, which comprises a puncture head, a transfusion hose, a dripping liquid observe window, a filter, and a pinhead. Top of puncture head is connected with the transfusion bottle, bottom of which in parallel is connected with a gas return hose and a transfusion hose. Back of puncture head is connected in line to a observe window, a crimpling switch and transfusion needles. A floating ball valve is serially connected on the top of transfusion pipe. When liquid in the bottle used up, floating ball valve is able to shut off transfusion hose to prevent the high level of liquid remaining in the transfusion hose from falling down continually and that prevent blood returning back to make sure transfusion more safety.
Description
Technical field:
This utility model relates to technical field of medical instruments, a kind of specifically disposable transfusion device.
Background technology:
Existing disposable transfusion device mostly is plastic material, generally comprise puncturing head, transfusion catheter, the dropping liquid observation window, filter, syringe needle, puncturing head upper end connection infusion bottle, the rear end parallel connection goes out muffler, transfusion catheter, the puncturing head rear end is by the transfusion catheter observation window of connecting successively, tighten switch, infusion needle, use easily, health, the problem that exists is the function that does not prevent blood back, during transfusion, does not note as patient or entourage, liquid in the bottle all is totally lost, tighten switch and in time do not change dressings or close, just may cause blood back, as the blood back overlong time, just need to change transfusion device, again acupuncture treatment is dangerous.
Summary of the invention:
The purpose of this utility model is the defective that overcomes the said goods, provides a kind of and improvedly on existing disposable transfusion device basis has a disposable transfusion device that prevents the blood back function automatically.。
This utility model is achieved in that improved Dispensable blood return-preventing transfusion device on existing disposable transfusion device basis, comprise puncturing head, transfusion catheter, dropping liquid observation window, filter, syringe needle, puncturing head upper end connection infusion bottle, the rear end parallel connection goes out muffler, transfusion catheter, the puncturing head rear end by transfusion catheter connect successively the dropping liquid observation window, tighten switch, infusion needle, the ball-cock assembly of also connecting on the top of transfusion catheter.
Consider manufacturing cost, above-mentioned ball-cock assembly can be used the dropping liquid observation window of existing transfusion device and realize, promptly the inner chamber of observation window insert in advance a proportion than the little slightly larger in diameter of water in the ball float of transfusion catheter internal diameter.
During use, observation window need keep a liquid level, so that the observation dropping liquid, ball float just in time floats over does not influence transfusion on the liquid level, and loses when not had liquid level when transfusion, ball float can be along with decline, up to the observation window lower end being exported to sealing, because vacuum action, transfusion stops automatically, so just stoped the further decline of liquid level in the tube for transfusion, the pressure of the generation of the residual liquid in the tube for transfusion at this moment is enough to stop blood to reflux.Added new drug in the infusion bottle when continuing transfusion, if when ball-cock assembly is attracted to the transfusion catheter mouth of observation window lower end, only with hand gently bullet once observation window ball float is floated.
Consider visual effect, observe easily, ball float can be made chromatic, as redness.
The beneficial effect that this utility model produces is: possessing on the function basis of common disposable transfusion device, have the function that prevents the transfusion device blood back, make transfusion safer.
Description of drawings:
Fig. 1 is the structural representation of this utility model embodiment 1
Among the figure, 1. puncturing head, 2. muffler, 3. observation window, 4. ball float, 5. transfusion catheter 6. tightens switch, 7. filter, 8. syringe needle.
The specific embodiment:
Embodiment 1: improved Dispensable blood return-preventing transfusion device on existing disposable transfusion device basis, comprise puncturing head (1), transfusion catheter (5), dropping liquid observation window (3), filter (7), syringe needle (8), puncturing head (1) upper end connection infusion bottle, the rear end parallel connection goes out muffler (2), transfusion catheter (5), puncturing head (1) rear end by transfusion catheter (5) connect observation window (3) successively, tighten switch (6), infusion needle (8), the ball float (4) of a proportion less than slightly larger in diameter warp in transfusion catheter of water arranged in the observation window inner chamber.
Claims (2)
1. blood return prevention disposable transfusion device, comprise puncturing head, transfusion catheter, dropping liquid observation window, filter, syringe needle, puncturing head upper end connection infusion bottle, the rear end parallel connection goes out muffler, transfusion catheter, the puncturing head rear end by transfusion catheter connect observation window successively, tighten switch, infusion needle, it is characterized in that at ball-cock assembly of the top of transfusion catheter series connection.
2. blood return prevention disposable transfusion device as claimed in claim 1 is characterized in that described floating ball valve structure is: insert a slightly larger in diameter in the ball float of transfusion catheter internal diameter in the dropping liquid observation window, this ball float proportion is less than the proportion of water.
