Description

Infusion device by pressing an air-pocket

This utility model belongs to medical apparatus and instruments, the air bag pressurizing transfusion device that uses in infusing fast, transfuse blood and rescue, perform the operation in particular for patient.

At present, the infusion set that in medical transfusion, uses, normally form by infusion bottle, hour hand head and tube for transfusion anastomosing, speed regulator, Murphy's burette, syringe needle, breather with it, in order to improve transfusion, transfusion speed, the method for raising speed commonly used has three kinds of electronic infusion pump method, 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, in addition the bolt of syringe repeatedly by both hands pull out, the continuous keying of propelling and 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.

This utility model improves at the problem that prior art exists, provide a kind of simple in structure, easy to use, cost is low, prevent to pollute, and can improve the air bag pressurizing transfusion device of transfusion, transfusion speed effectively.

This utility model is achieved by following manner: a kind of air bag pressurizing transfusion device, comprise infusion bottle and bottle stopper thereof and intravenous transfusion device, wherein intravenous transfusion device by insert the hour hand head I in the infusion bottle and the tube for transfusion of lower end thereof and the speed regulator that on tube for transfusion, sets gradually, Murphy's burette, syringe needle is formed, this utility model is that air bag prelum and pressure display unit are set on this basis, promptly at the infusion bottle place air bag prelum and pressure display unit is set.They are respectively by minute hand head and hour hand head II and infusion bottle connection.

Said air bag prelum be by air bag and on the breather cheek valve I and by the trachea II and be arranged on air purifier on the breather II, breather cheek valve II and three way cock's I, the breather cheek valve III of threaded three way cock's II and lower port thereof, the minute hand head, atmospheric pressure compensating breather cheek valve and breather I thereof are formed, wherein three way cock's I is dead with cap seal, the lower port of threaded three way cock's II is connected with the breather of being drawn by air purifier, its upper port and minute hand head join, and the minute hand head inserts in the infusion bottle, and its right output port and atmospheric pressure compensating breather cheek valve and breather I thereof are connected.

Said pressure display unit can be made up of housing and interior spring, buoy, isolated film, base thereof, and inserts in the infusion bottle by the hour hand head II of breather and front end thereof, so it can directly show the pressure value size in the infusion bottle.

Said atmospheric pressure compensating breather cheek valve can by valve body and on through hole, spool form, also can adopt existing various check valve.

Said breather cheek valve II and breather cheek valve III can and go up the otch that is provided with and form by cylindrical (or the conical) valve body of top closure, also can by untight cylindrical (or taper shape) valve body in top and on end cap form.These two kinds of breather cheek valve II, III also can adopt the structure of atmospheric pressure compensating breather cheek valve in addition.

Its work process is: extruding gasbag at first, at this moment the breather cheek valve I on it is closed, gas enters the breather cheek valve II by the breather II, enter air purifier then, gas enters breather cheek valve III and threaded three way cock's II after filtration, enter in the infusion bottle by the minute hand head at last, make the increased pressure in the infusion bottle, force liquid to enter in the person by intravenous transfusion device fast, when unclamping air bag, the breather cheek valve I on it is opened, air is entered in the air bag by the external world, this moment, breather cheek valve II and breather cheek valve III were closed, and the liquids and gases in air purifier and the infusion bottle can not backflow like this, have reduced pollution.Because the air purifier upper port connects three way cock's I, its right output port is dead with cap seal, can open and inject in air purifier sterile liquid during use, and the clean-up effect when liquid level exceeds 1～2 centimetre on breather cheek valve II top usually is best.Insert the liquid level in the infusion bottle that minute hand head in the infusion bottle should exceed reversal of the natural order of things in addition, like this tip waste time approximately suddenly slap  guanidine standing grain a surname admire ッ whore   hire  waste time the happy legendary venomous insect  of elegant Yin chaste tree  flag lush Lu benzene chant  cut off the feet guess 5 of the great ilium rimes of an ancient pot the Huangshui River urinate  protect the stewing Zhuang brocade ⑷ Yun order palm of    ふ set out branch benzene chant the great health of  moon bright the Huangshui River hit dredge the  Japan of wasting time and search the happy few  grasshopper Herba Marsileae Quadrifoliae of the angry myna   of  drought and carry on a shoulder pole ㄈ blood).The atmospheric pressure compensating breather cheek valve can be communicated with (also can directly insert in the infusion bottle with syringe needle) by the breather I with the right output port of threaded three way cock's II, its effect is, when extruding gasbag, when perhaps the infusion bottle internal pressure is higher than atmospheric pressure, the atmospheric pressure compensating breather cheek valve is closed all the time, can prevent liquid leakage; When stopping extruding gasbag, pressure in the infusion bottle descends, when being lower than atmospheric pressure, the atmospheric pressure compensating breather cheek valve is opened automatically, in the extraneous air admission infusion bottle, make the pressure in the infusion bottle be not less than atmospheric pressure all the time, can make like this to enter intravenous transfusion device in the infusion bottle liquid continuously, thereby prevent the backflow of human vas inner blood and solidify and block syringe needle.Pressure display unit is marked with scale, therefore can observe directly the pressure size in the infusion bottle.

This utility model is compared with prior art, have rational in infrastructure, easy to use, cost is low, prevent to pollute, can improve characteristics such as transfusion or transfusion speed.
