Abstract

The utility model provides a plurality of check valves of establishing ties on the dropping funnel, each check valve set up two feed liquor ends and a play liquid end, and feed liquor end on the check valve links to each other with the burette, and another feed liquor end goes out the liquid end with last one -level check valve establishes ties that disposable continuous transfusion system of multichannel, it is at known disposable transfusion system. Each way infusion bottle from high to low hangs, and the check valve that links to each other with each infusion bottle burette is then establish ties according to order from low to high. The check valve of lowest order, its liquid end links to each other with the dropping funnel. Hang and export the liquid medicine through the check valve of lowest order to the dropping funnel at first at the infusion bottle of highest order, when the output liquid level is the same with time high -order infusion bottle liquid level in the burette, the infusion bottle beginning automatically output liquid medicine of an inferior high position to this analogizes, liquid medicine in all infusion bottles of can continuous output hanging. Medical personnel once only insert multichannel or overall infusion bottle, can improve work efficiency, reduce medical malpractice and take place.

Description

Disposable multiway continuous transfusion system

Art

This utility model relates to a kind of disposable multiway continuous transfusion system, and specifically one does not need midway to change infusion bottle, the transfusion device of energy continuous transfusion.

Background technology

At present, known transfusion device is connected to form by intravenous needle, infusion tube, liquid medicine filter, flow regulator, dropping funnel, dropper, bottle plug puncture unit, air inlet pipe air filter.In infusion process, when a bottle liquid medicine is soon totally lost, needs to change infusion bottle in time and continue transfusion, because replacing infusion bottle is skilled work, must have been come by medical personnel, numerous patients needs to change infusion bottle at any time, and this is concerning hospital, add the workload of medical personnel on the one hand, increase doctors and patients' cost, on the other hand, owing to frequently changing infusion bottle, also increase input air and even input medicinal liquid by mistake, cause the danger of malpractice.And transfusion is also made troubles to patient and family members for a long time.

Summary of the invention

The workload that infusion bottle increases to medical personnel is frequently changed in order to reduce existing transfusion device, eliminate consequent malpractice hidden danger, this utility model provides a kind of disposable multiway continuous transfusion system, medical personnel are when giving patient fluid infusion, can disposable access multichannel even all infusion bottles, the medicinal liquid of each infusion bottle exports in order continuously, does not need midway to change infusion bottle.This utility model solves the technical scheme that its technical problem adopts: at dropping funnel and the check-valves of connecting between dropper of known disposable transfusion device, defeated several bottles of liquid are needed just to connect several check-valves, each check-valves arranges two liquid feeding ends and a liquid outlet, a liquid feeding end of check-valves is connected with dropper, and another liquid feeding end is connected with upper level check-valves liquid outlet.Each road infusion bottle hangs from high to low, and the check-valves be communicated with it is then by sequential series from low to high.The check-valves of lowest order, its liquid outlet is connected with dropping funnel.The infusion bottle being suspended on highest order exports medicinal liquid by the check-valves of lowest order to dropping funnel at first, when exporting liquid level in dropper and being identical with time high-order infusion bottle liquid level, the infusion bottle of a secondary high position starts automatically to export medicinal liquid, by that analogy, can export the medicinal liquid in all infusion bottles of suspension continuously.The beneficial effects of the utility model are, medical personnel can disposable access multichannel or whole infusion bottles, and the medicinal liquid in each infusion bottle can export by Automatic continuous, reduces medical personnel's working strength, decreases malpractice hidden danger.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, this utility model is further illustrated.

Fig. 1 is utility model check-valves vertical section structural map.

In Fig. 11, first order check-valves, 2, second level check-valves, 3, third level check-valves, 4, liquid feeding end a, 5, liquid feeding end b, 6, liquid outlet, 7, valve block, 8, one road dropper, 9, two road droppers, 10, three road droppers

Detailed description of the invention

In FIG, first order check-valves (1) is provided with liquid feeding end a (4), liquid feeding end b (5), liquid outlet (6) and valve block (7).Check-valves at different levels on the dropper of each road are cascaded, the liquid feeding end b of every one-level check-valves connects with the liquid outlet of upper level check-valves, and the valve block (7) in check-valves is buoyancy material, and shape can be lamellar, also can be spherical, prevent medicinal liquid from being flow backwards by liquid feeding end b.The liquid feeding end a (4) of first order check-valves (1) is connected with a road dropper (8) of transfusion device, the liquid feeding end a of second level check-valves (2) is connected with two road droppers (9) of transfusion device, the liquid feeding end a of third level check-valves (3) is connected with three road droppers (10) of transfusion device, by that analogy.The liquid outlet (6) of the first order check-valves of lowest order is connected with infusion unit titrimeter.The infusion bottle be connected with a road dropper (8) is suspended on highest order, and the infusion bottle be communicated with two road droppers (9) is suspended on a time high position, and by that analogy, each infusion bottle position of suspension can not be overlapping.In order to ensure that the position of each infusion bottle does not hang mistake, on check-valves, the length of dropper must be the length of low level, and high-order is short,

And reference numerals is answered on the bottle plug puncture unit of each road dropper, even distinguished with different colors.During transfusion, the infusion bottle hanging on highest point connects by the bottle plug puncture unit that first Yong Yu mono-road dropper (8) is connected, medicinal liquid is injected first order check-valves (1), again the medicinal liquid in secondary high-order infusion bottle is injected second level check-valves (2), by that analogy, the medicinal liquid that the check-valves at different levels of series connection inject each infusion bottle by order from low to high can be infused.

Claims (1)

1. a disposable multiway continuous transfusion system, comprise intravenous needle, infusion tube, liquid medicine filter, flow regulator, dropping funnel, dropper, bottle plug puncture unit, air inlet pipe air filter connects to form, it is characterized in that between dropping funnel with dropper, be provided with multiple check-valves of connecting, each check-valves arranges two liquid feeding ends and a liquid outlet, one of them liquid feeding end is connected with dropper, another liquid feeding end is connected with upper level check-valves liquid outlet, each road dropper connects a check-valves, the check-valves of lowest order, its liquid outlet is connected with dropping funnel, infusion bottle on the dropper of each road hangs from high to low, coupled check-valves is then by sequential series from low to high.
