Abstract
The utility model relates to medical instruments, in particular to a safe infusion device. The safe infusion device is characterized in that a drop-shaped floating ball is arranged in a Murphy dropper, a guide rod is arranged at the lower end of the drop-shaped floating ball, the lower end of the guide rod is inserted in an infusion tube at the lower end of the Murphy dropper, and a liquid medicine pressurizer is connected between an infusion control valve and a venous infusion syringe needle in series. In the infusion process of a patient, when liquid medicine in a liquid medicine bottle or a liquid medicine bag is used up, along with reduction of the liquid medicine in the Murphy dropper, under the action of the guide rod, the floating ball gradually moves downwards until the floating ball accurately falls on and blocks an outlet of the Murphy dropper, at the moment, the liquid medicine in the infusion tube will not enter the blood vessel of the patient any more, and it is avoided that the blood flows back or air enters the blood vessel; when infusion can not be performed due to blood coagulation, the liquid medicine pressurizer is squeezed, so that pressure is generated by the liquid medicine in the liquid medicine pressurizer and the infusion tube in front of the liquid medicine pressurizer, and the liquid medicine with the pressure is injected by the syringe needle to burst through the coagulated blood so that infusion can continue. The safe infusion device has the advantages of being easy to operate and safe to use.
Description
Technical field
This utility model relates to medical apparatus technical field, specifically a kind of safe transfusion device that uses safety, can alleviate nursing intensity.
Background technology
As everyone knows, venous transfusion is owing to having instant effect, advantages such as expense is low and being used widely, that to treat at present various diseases patient important, common hands section, existing transfusion device comprises intravenous infusion syringe, Murphy's burette, transfusion control valve, air filter, threeway infusion plug, tube for transfusion and airway, intravenous infusion syringe, Murphy's burette is contacted through tube for transfusion mutually with threeway infusion plug, air filter is connected with threeway infusion plug through airway, when patient infuses, all need accompanying and attending to of relatives or medical personnel, the effect of accompanying and attending to is to look after patient on the one hand, be on the other hand when patient infuses, entourage will observe the situation of transfusion, when the medicinal liquid in infusion bottle is about to be totally lost, change in time or notify medical personnel to dispose, otherwise, can cause blood backflow or air intravasation phenomenon, if blood backflow, may make to infuse unsuccessfully, need again to patient, have an acupuncture treatment, if enter air in blood vessel, threatening patient's life, in addition, movement due to patient in infusion process makes syringe needle produce displacement, cause bulging pin and blood coagulation and stop the phenomenon of transfusion, as processed not in time, must again puncture or bury syringe needle underground.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of safe transfusion device simple to operate is provided.
This utility model can reach by following measure:
A kind of safe transfusion device, comprise intravenous infusion syringe, Murphy's burette, transfusion control valve, medicinal liquid prelum, air filter, threeway infusion plug, tube for transfusion and airway, intravenous infusion syringe, Murphy's burette is contacted through tube for transfusion mutually with threeway infusion plug, air filter is connected with threeway infusion plug through airway, tube for transfusion between intravenous infusion syringe and Murphy's burette is provided with transfusion control valve, it is characterized in that being provided with in Murphy's burette drops ball float, the lower end of drops ball float is provided with guide post, the lower end of guide post is inserted in the tube for transfusion of Murphy's burette lower end, the medicinal liquid prelum of connecting between transfusion control valve and intravenous infusion syringe.
Medicinal liquid prelum described in the utility model can adopt elasticity liquid storage ball, also can adopt one section of corrugated tube, and one end of elasticity liquid storage ball or corrugated tube is provided with inlet, and the other end is provided with liquid outlet, and inlet place can be provided with check valve, with handled easily.
When this utility model is infused for patient, ball float in Murphy's burette is floated by medicinal liquid, medicinal liquid enters Murphy's burette by medicinal liquid bottle or bag through tube for transfusion, by Murphy's burette, exported again, in tube for transfusion and intravenous infusion syringe input patient vessel, by transfusion control valve, control transfusion speed, when medicinal liquid bottle or bag are when be totally lost, along with the medicinal liquid in Murphy's burette reduces, ball float gradually moves down under the effect of guide post, until accurately drop to the outlet of Murphy's burette it is clogging, now the medicinal liquid in tube for transfusion can not enter in patient's blood vessel again, blood backflow or air intravasation phenomenon have been avoided, when occurring that phenomenon is not infused in blood coagulation, close transfusion control valve prerequisite under push medicinal liquid prelum, make the medicinal liquid in the tube for transfusion before medicinal liquid prelum and medicinal liquid prelum produce pressure, medicinal liquid with pressure is sprayed by syringe needle, blood coagulation is washed open and is continued transfusion, have advantages of simple to operate, use safe.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail:
As shown in the figure, a kind of safe transfusion device, comprise intravenous infusion syringe 1, Murphy's burette 2, transfusion control valve 3, air filter 4, threeway infusion plug 5, tube for transfusion 6 and airway 7, intravenous infusion syringe 1, Murphy's burette 2 and threeway infusion plug 5 are contacted mutually through tube for transfusion 6, air filter 4 is connected with threeway infusion plug 5 through airway 7, the tube for transfusion 6 that intravenous infusion syringe 1 and Murphy's burette are 2 is provided with transfusion control valve 3, the structure of above-mentioned each ingredient and the interconnected relationship between them are same as the prior art, and this does not repeat.Feature of the present utility model is in Murphy's burette 2, to be provided with drops ball float 8, the lower end of drops ball float 8 is provided with guide post 9, the lower end of guide post 9 is inserted in the tube for transfusion 6 of Murphy's burette 2 lower ends, the medicinal liquid prelum 10 of connecting between transfusion control valve 3 and intravenous infusion syringe 1.
