Description

Apparatus for quickly blood transfusion and infusion

This utility model relates to infusion device, particularly a kind of quick blood transfusion and infusion device.

At present, the infusion device that in medical treatment, uses, normally infusion bottle, hour hand head and tube for transfusion anastomosing with it, speed regulator, Murphy's burette, syringe needle, breather are formed, and in order to improve transfusion, transfusion speed, method commonly used has electronic infusion pump method.Three kinds of threeway syringe push injection and extruding tube for transfusion accelerated process etc.First kind is to adopt electric principle, promptly after the energising, the infusion pump rotation is injected into the liquid in the tube for transfusion that connects on the pump in the blood vessel of human body, this method complex structure, operation strict, cost an arm and a leg (every price is more than thousands of units) therefore are unfavorable for applying.Second method is to connect a threeway on tube for transfusion, promptly connect a threeway on the tube for transfusion that between Murphy's burette and syringe needle, is connected, come the opening and closing tube for transfusion by the switch in the threeway, liquid is at first entered in the syringe, and then inject in the blood vessel of human body by threeway with syringe.Though this method processing ease, but need the people constantly to inject, therefore use inconvenience, the bolt of syringe is pulled out by both hands repeatedly in addition, advance and the continuous keying of three-way cock, pollute easily, particularly when syringe or threeway folding are tight, easily cause leaked liquid, even cause gas to inject endovascular serious consequence.The third method is with the hands alternately to push tube for transfusion, operation inconvenience, and effect is relatively poor, as lack of skill, does not have the purpose of quickening transfusion sometimes, the destruction of also causing blood cell when transfusing blood in addition easily.Except that above-mentioned three kinds of methods, also having a kind of method is exactly with syringe pressure in the injected gas increase infusion bottle in infusion bottle, and need thrust and extract syringe needle repeatedly, the sealing property of infusion bottle plug is reduced, liquid leakage when serious, the contaminated chance of liquid increases simultaneously, and operation is also extremely inconvenient.Chinese patent CN89206762.4 discloses a kind of air bag pressurizing transfusion device again in the recent period, this technology is that air bag prelum and pressure display unit are set on the basis of the above, though can improve the speed of blood transfusion or transfusion, can directly read the size of pressure value again, but this technology is owing to be to adopt the interior pressure structure of directly carrying out air pressurized in infusion bottle, airborne so harmful virus just directly contacts with medicine or blood plasma with pathogenic bacteria, pollutes easily, and is also inconvenient to the transfusion bags use in addition.

This utility model improves at the problem that prior art exists, and provides a kind of simple in structure, easy to use, can the antipollution outer a kind of quick blood transfusion and infusion device that pressurizes.

This utility model is achieved by following manner: a kind of quick blood transfusion and infusion device, comprise blood transfusion and infusion part and quick pressures partially, wherein the blood transfusion and infusion part is by the blood transfusion and infusion bag, blood transfusion and infusion pipe and the Murphy's burette that upward is provided with thereof, flow rate regulating valve and syringe needle are formed, feature of the present utility model is: outer pressure structure is adopted in said quick pressures partially design, be that it has a shell and places the expansible air bag of inflatable volume in it, the air pressurized pipe that is communicated with air bag and the tee T and the breather cheek valve that upward are provided with, and the pressurization skin of air pressurized tube end setting is asked, wherein said enclosure designs be by hinge connect can by zip and snap close sealed and a symmetric left side, both sides, right shell body, they are on the left side, the lower end is respectively equipped with hook and outlet, constitute the left side of shell simultaneously, right shell body is designed to right-angled trapezium, a wherein long limit should be in plumbness (also may tilt a little sometimes) when the operating position, here said right-angled trapezium can certainly be other shape, as trapezoidal or triangle.

This utility model uses and work process is: at first with the left side of shell, right shell body is opened, put into the air bag of blood transfusion and infusion bag (alleged transfusion bags or transfusion bag usually) and inflatable, the left side of closing then, right shell body is also sealed with zip and snap close, hang on the blood transfusion and infusion frame by hook, draw blood transfusion and infusion pipe and the disposable common blood transfusion and infusion pipe of air pressurized Guan Bingke plug-in mounting respectively in the shell body outlet, after this, each several part can be regulated and syringe needle is inserted sick blood vessel of going into, situation according to concrete patient, with holding tight and unclamping the pressurization ball, so just inflation pressurization in the air bag of the inflatable in placing shell, the air bag volume is increased to expand, the exterior circumferential of extruding blood transfusion and infusion bag, quicken to improve the speed of blood transfusion and infusion, the control of blood transfusion and infusion speed can be controlled by the pressurization ball, can push the pressurization ball when improving as need fast the air bag volume is increased fast, when reducing, can open lid outside aerofluxus the reducing air bag volume in the threeway as need.

This utility model is compared with prior art, has simple in structurely, and blood transfusion and infusion speed is fast, and is easy to use, and most importantly control prevented pollution easily, has easy processing and manufacturing simultaneously, and cost is low, and is easy to utilize.
