Abstract
The utility model relates to a disposable vein infusion device, which is characterized in that the utility model is composed of a liquid feeding part, a Murphy's dropper, an infusion pipe, a regulator, and an infusion needle head. The liquid feeding part is an open plastic infusion bottle; the regulator is provided an upper regulating pulley wheel and a lower regulating pulley wheel. The utility model can promote blood return flow in puncture, enhances success rate, reduce labor intensity, and can effectively solve the problems of little quantity and more groupings in children infusion.
Description
This utility model relates to medical apparatus and instruments, particularly a kind of disposable transfusion device that is used for venous transfusion.
Existing disposable transfusion device is a closed, is made up of bottle stopper puncture needle, exhaust needle, tube for transfusion, Mao Feishi dropper, actuator, infusion needle.Such situation often appears when carrying out venipuncture with this closed disposable transfusion device, be that infusion needle retreats to puncture failure when subcutaneous, or the nurse think infusion needle intravasation but always lose blood back, just push the following partly tube for transfusion of Mao Feishi dropper and promote blood back, so that patient's hypohydrops or vein blood vessel front end are broken.In addition, to infant and slow for overcoming blood back when carrying out venipuncture because of dehydration, the bad patient of shock blood circulation, need earlier to extract 10% glucose or normal saline number milliliter with 5 milliliters of syringes, joint sword-shaped needle one people draws back blood one people's venipuncture.Again scalp acupuncture is received on the transfusion device after puncturing successfully.This not only can increase patient's infection chance but also strengthen nurse's workload.
This reality has novel purpose to provide a kind of improved disposable transfusion device, to remedy the existing slow defective of disposable transfusion device blood back, improves puncture success rate.And can verify at any time that in infusion process infusion needle is whether in blood vessel.
Task of the present utility model is finished like this, designed a kind of disposable intravenous infusion set of forming by feed flow part, Mao Feishi dropper, tube for transfusion, actuator and infusion needle, its feed flow partly is the open plastic infusion bottle that the bottleneck of hanging bottle ring and band bottle cap is arranged, and its actuator has upper and lower two to regulate pulley.After the small amount of liquid that falls earlier during transfusion washes open infusion bottle and tube for transfusion, syringe needle, pour medicinal liquid into and drain air in the tube for transfusion, emit small amount of liquid again and close the following adjusting pulley of actuator, the limit flanging upwards pushes away the adjusted pulley of actuator then, the liquid in two tube for transfusions of regulating between the pulley is clamp-oned the Mao Feishi dropper make it to form one section vacuum.Unclamp after infusion needle thrusts skin and regulate pulley down, the negative pressure that vacuum causes can impel blood to reflux, and proves and punctures successfully.Unclamp the adjusted pulley this moment again, regulates flow, and liquid level can be infused.So transfusion, convenient, reliable, it is few also can to solve the infantile infusion amount effectively, the problem that grouping is many.
In actual use, also can open infusion bottle, still use bottle stopper puncture needle and exhaust needle to carry out closed transfusion.
As a kind of embodiment of the present utility model, its actuator also can be formed by upper and lower two dull joint pulley actuator serial connections.
Embodiment describes this utility model below in conjunction with accompanying drawing.
Fig. 1 is the open short blood back disposable intravenous infusion set sketch map of this utility model embodiment.
As shown in Figure 1, have the open plastic infusion bottle of the bottleneck 3 of hanging bottle ring 2 and band bottle cap 4 to connect Mao Feishi dropper 51 time, tube for transfusion 6 passes actuator 8, adjusted pulley 7 is arranged on the actuator 8 and regulate pulley 9 down, and tube for transfusion 6 is termination infusion needle 10 not.
Claims (2)
1, a kind of disposable intravenous infusion set, form by feed flow part, Mao Feishi dropper, tube for transfusion, actuator and infusion needle, it is characterized in that said feed flow partly is the open plastic infusion bottle that the bottleneck of hanging bottle ring and band bottle cap is arranged, said actuator has upper and lower two to regulate pulley.
2, disposable intravenous infusion set according to claim 1 is characterized in that said actuator is to be formed by upper and lower two dull joint pulley actuator serial connections.
