Description
Technical field
This utility model relates to a kind of transfusion device, specifically a kind of intravenous transfusion device with precision transfusion regulator.
Background technology
Transfusion device is conventional medical apparatus and instruments, there is following defect in current transfusion device: when the medicinal liquid in infusion bottle enters liquid-transport pipe-line by the feed liquor pin mouth of transfusion device, because the feed liquor pin hole position of existing transfusion device is higher, be positioned at the tip of pin stalk, when the fluid level of bottleneck is lower than feed liquor pin hole position, medicinal liquid just can not enter needle tubing completely and input in body, and clinical nurse finds that often every bottle of liquid medicine all can waste 3-5 milliliter, cause liquid waste, dosage is inaccurate; After patient completes transfusion, transfusion needle is often directly put into sharp weapon box or is temporarily fixed on the rubber stopper of infusion bottle by injection needle by medical personnel, and infusion needle is exposed to outside and easily causes stabbing of medical personnel, and easily the danger of infection occurs; In infusion process, fail to change in time if liquid drips off, large quantity of air is then likely caused to enter in blood circulation of human body system, thus bring out gas embolization and cause patient uncomfortable, even be in peril of one's life, changing medicinal liquid is at present all generally that nurse manually changes, once change not in time, then may pass into air in tube for transfusion and enter human body, extremely dangerous; During transfusion, some medicine needs strict control transfusion speed, and preventing can not load and cause discomfort because infusing the too fast patient body that causes, but is all the experience regulating transfusion device with nurse at present usually, and speed regulation process is slow, error is large, can not meet user demand.For above problem, need to improve existing transfusion device.
Utility model content
The purpose of this utility model be to provide a kind of can make full use of medicinal liquid, can fine adjustment infusion rate, can prevent air in infusion process from entering the intravenous transfusion device with precision transfusion regulator of blood, use safety, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of intravenous transfusion device with precision transfusion regulator, comprise tube for transfusion, one end of described tube for transfusion is provided with puncture needle, the inlet of puncture needle is near the hub portion of puncture needle, the junction of puncture needle and tube for transfusion is provided with exhaustor, described tube for transfusion is provided with successively along transfusion direction and drips kettle, precision transfusion regulator and liquid medicine filter, the other end of tube for transfusion is provided with transfusion needle, and the needle stand of transfusion needle is provided with needle handle; Sleeve pipe is provided with outside described tube for transfusion between kettle and puncture needle, described sleeve pipe is for placing transfusion needle and needle handle, one end sealing of sleeve pipe, other end opening, the side, side of sleeve pipe is provided with the joint-cutting, the first card seam and the second card seam that vertically arrange, the lower end of described joint-cutting extends to the opening of sleeve pipe, and the first card seam that upper end and the level of joint-cutting are offered communicates, and the lower end and second of the first card seam is blocked to stitch and communicated and form one is established needle handle draw-in groove for card; Described kettle bottom angled is inwardly arranged, drip in kettle and be provided with floating plug, floating plug top perimeter is provided with leakproof thin film circle, truncated cone-shaped is set to bottom described floating plug, floating plug base diameter is less than tube for transfusion internal diameter, bottom floating plug, centre position is fixedly connected with and leads stopper rod, leads stopper rod diameter and reduces successively from top to bottom, leads stopper rod lower end and is arranged in tube for transfusion; Described precision transfusion regulator comprises base, pad and adjusting knob, described base central authorities are provided with groove, recess sidewall is provided with female thread, adjusting knob is provided with the external screw thread with female thread adaptation, described base outer wall is provided with scale, base is provided with the through hole passed for tube for transfusion, and through hole is communicated with groove, and described pad is arranged on the connectivity part of through hole and groove.
As further program of the utility model: the sealed end of described sleeve pipe is provided with medical cotton pad, the upper surface of described first card seam is provided with for coordinating with the second card seam with the elastic projection clamping needle handle, and the bottom of elastic projection is arc.
As this utility model further scheme: the density of described floating plug is less than the liquid-tight degree of infusing medicine, described leakproof thin film circle is medical plastic, described in lead stopper rod length be 5cm.
As this utility model further scheme: described base adopts one-shot forming plastics to make.
Compared with prior art, the beneficial effects of the utility model are: the inlet of this utility model puncture needle, near needle stand position, reduces feed liquor liquid level, when making transfusion, can make full use of the medicine in infusion bottle, not cause waste; Tube for transfusion is provided with the sleeve pipe depositing transfusion needle and needle handle, and after transfusion terminates, medical personnel only need hand-held needle handle, transfusion needle is clamped in the draw-in groove of sleeve pipe, can play a protective role to syringe needle, can prevent again to stab accident, avoid medicine simultaneously and to outflow the pollution caused; Drip in kettle the floating plug arranged effectively to stop air in transfusion device and enter phenomenon in blood of human body, because floating plug density is lower than transfusion liquid density, when there is liquid in a kettle, floating plug floats over liquid upper, and transfusion can smooth and easyly be carried out, when in a kettle, liquid gradually lacks, floating plug sinks with liquid level, and final arrival is dripped bottom kettle, blocks and drips kettle outlet at bottom, leakproof thin film circle prevents air from entering in tube for transfusion further downwards, improves the safety of patient in infusion process; The base of precision transfusion regulator is provided with scale, and by rotation of adjustment knob, extruding tube for transfusion thus reach the effect of regulating transfusion speed, medical personnel are according to scale rotation of adjustment knob, and flow-control is more accurate, safe and reliable.
