Description
Technical field
This utility model relates to technical field of medical instruments, is a kind of blood return prevention automatic liquid-stopping safe transfusion system specifically.
Background technology
Transfusion device be a kind of be mainly used in venous transfusion through aseptic process, the common disposable medical treatment consumptive materials of setting up passage between vein and medicinal liquid, often see in clinical, but transfusion device common at present closes to an end in transfusion, medicinal liquid can not be found when will be totally lost at once timely, often cause blood backflow, so-called blood backflow extracts venipuncture needle after having infused exactly not in time, blood in human body can be back in infusion tube through venipuncture needle, both cause misery to patient, also result in the waste of medicinal liquid; And common transfusion device is in patient infusion process, if client need goes to toilet etc. during big-movement demand, because current venipuncture needle section and tube for transfusion are grafting, are easy to cause venipuncture needle section and tube for transfusion to disconnect, thus cause the generation of unsafe condition.
Summary of the invention
Goal of the invention of the present utility model is to overcome after transfusion that current existing transfusion device exists terminates and is not easy to discover, cause blood backflow, in infusion process, big-movement causes the defect that venipuncture needle end and tube for transfusion disconnect, thus realize automatic liquid-stopping when a kind of transfusion closes to an end and report to the police, the blood return prevention automatic liquid-stopping safe transfusion system that venipuncture needle section and tube for transfusion can not disconnect.
For achieving the above object, the technical solution of the utility model is: a kind of blood return prevention automatic liquid-stopping safe transfusion system, comprise the tube for transfusion of transparent material, described tube for transfusion is from first to last disposed with bottle plug puncture unit, infusion unit titrimeter, liquid medicine filter, flow regulator and venipuncture needle, the syringe needle that described infusion unit titrimeter periphery is provided with elastic material overlaps temporarily admittedly, and syringe needle puts the observation window of liquid level having strip temporarily admittedly; Bottom, described infusion unit titrimeter medial wall is provided with liquid-level probe, and described liquid medicine filter bottom is provided with automatic liquid-stopping alarm mechanism, when liquid level in infusion unit titrimeter is lower than liquid-level probe, and the action of automatic liquid-stopping alarm mechanism, tube for transfusion is stuck and send alarm sound; The puncture needle dismounting knot be threaded is provided with between flow regulator and venipuncture needle.
Described automatic liquid-stopping alarm mechanism comprises only liquid valve block and alarm, and described only liquid valve block is sleeved on tube for transfusion periphery, and alarm is fixedly installed on only liquid valve block side, described alarm is provided with infusion monitoring switch.
Described syringe needle temporarily solid cover is aseptic sponge or aseptic rubber, penetrates temporarily, avoid stabbing medical worker and patient for venipuncture needle.
The operation principle of blood return prevention automatic liquid-stopping safe transfusion system of the present utility model: open infusion monitoring switch, start transfusion, when transfusion closes to an end, medicinal liquid in medicine bottle flows to end, medicinal liquid only in remaining infusion unit titrimeter, medicinal liquid liquid level in infusion unit titrimeter also declines gradually, when the medicinal liquid liquid level in infusion unit titrimeter drops to below liquid-level probe, liquid-level probe is to automatic liquid-stopping alarm mechanism signal, only the action of liquid valve block is stuck by tube for transfusion, alarm sends alarm sound, after tube for transfusion is stuck, medicinal liquid stops both continuing transfusion at once, also blood backflow can not be caused, alarm sound makes medical worker learn, and transfusion terminates, carry out at once pulling out pin, terminate infusion process.
The beneficial effect of blood return prevention automatic liquid-stopping safe transfusion system of the present utility model:
1. at blood return prevention automatic liquid-stopping safe transfusion system of the present utility model, when transfusion closes to an end, liquid-level probe is to automatic liquid-stopping alarm mechanism signal, and only the action of liquid valve block is stuck by tube for transfusion, and alarm sends alarm sound, after tube for transfusion is stuck, medicinal liquid stops both continuing transfusion at once, also can not cause blood backflow, thus avoid the misery because blood backflow causes to patient, save medicinal liquid simultaneously, can not liquid waste have been caused.
2. at blood return prevention automatic liquid-stopping safe transfusion system of the present utility model, the puncture needle dismounting knot be threaded is provided with between flow regulator and venipuncture needle, in infusion process, even if patient has big-movement activity, also venipuncture needle section and tube for transfusion can not be caused to disconnect, ensure that the safety of infusion process.
