Abstract

The utility model relates to a controllable pressurizer for quick transfusion, which is a pressurizing device which can transfuse quickly for patients. The controllable pressurizer for quick transfusion is mainly composed of an air bag, an air inlet pipe, a pressure gauge, a three-way device, a three-way control switch, a connecting pipe, etc., wherein, the air bag is respectively connected with the air inlet pipe and the pressure gauge through a three-way pipe and the connecting pipe; the three-way control switch is also arranged on the three-way pipe; the upper end head of the air inlet pipe forms an oblique opening shape. The trouble of pressurizing by a large injector when quick transfusion is needed is overcome by the controllable pressurizer for quick transfusion. Compared with a transfusion pump, the controllable pressurizer for quick transfusion also has the advantages of simple structure and easy preparing. The controllable pressurizer for quick transfusion can be widely suitable for situations which need quick transfusion, such as patient salvage, etc.

Description

The controlled supercharger of quick transfusion

This utility model provide a kind of can in infusion bottle, produce that size elevated pressures, pressure can be controlled, can be patient's controlled supercharger of quick transfusion of transfusion fast.

At present, the transfusion device that uses in the hospital is all realized transfusion under normal pressure, although a speed of transfusion can be regulated, range of accommodation is too little.When giving emergency treatment to a patient or doing certain special treatment and need pressurize fast transfusion, above-mentioned general infusion set then can't be suitable for.In order to address the above problem, the method that adopts infusion pump usually or in infusion bottle, inject supercharging air with big syringe.Infusion pump costs an arm and a leg, is difficult to popularize; With big injector to inject air, operate loaded down with trivial details, liquid and leak outside easily.

The purpose of this utility model is: on the basis of existing general infusion set and infusion pump, improve, design a kind of simple in structure, easy to use, can be in infusion bottle the controlled supercharger of quick transfusion that can control of increase pressure and size.

This utility model be achieved in that this fast the controlled supercharger of transfusion form by air bag, Pressure gauge, air inlet pipe, tee T, connection tube each several part.Three connectors at tee T are connected with air bag, Pressure gauge, air inlet pipe respectively, control its connected state by the threeway gauge tap.Air inlet pipe inserts in the space on infusion bottle top, and tube for transfusion inserts in the liquid of infusion bottle bottom.When the needs pressurization is infused fast, the threeway gauge tap is placed air bag, Pressure gauge, the state that air inlet pipe communicates, hold air bag and pressurize continuously, the pressure of infusion bottle upper space is increased, simultaneously, Pressure gauge demonstrates pressure value, like this, can infuse fast to patient by tube for transfusion.When pressure reached predetermined value, with the state that the threeway gauge tap places air inlet pipe to communicate with Pressure gauge, institute's plus-pressure can be kept the quick transfusion of a period of time.When pressure is reduced to predetermined value, holds air bag and continue pressurization.

Advantage of the present utility model is: simple in structure, with low cost; Swift to operate, easy to use.

Concrete structure of the present utility model is provided by following drawings and Examples:

Accompanying drawing has provided this sketch map of being connected with tube for transfusion of controlled supercharger of transfusion and infusion bottle fast.

In the accompanying drawings, [1] is infusion bottle, and [2] are tube for transfusion, and [3] are air inlet pipe, and [4] are Pressure gauge, and [5] are air bag, and [6] are connection tube, and [7] are tee T, and [8] are the threeway gauge tap.

The controlled supercharger of transfusion is made up of air bag [5], Pressure gauge [4], air inlet pipe [3], tee T [7], connection tube [6] and threeway gauge tap [8] fast, and medicinal liquid transfers to patient through tube for transfusion [2].Air bag [5] is connected with air inlet pipe [3] and Pressure gauge [4] respectively by tee T [7] and connection tube [6].On tee T [7], also be provided with threeway gauge tap [8].Threeway gauge tap [8] has two positions, and one of them position all communicates air bag [5], Pressure gauge [4] and air inlet pipe [3] three, and another position only makes Pressure gauge [4] and air inlet pipe [3], and the two communicates.When needs are infused fast, threeway gauge tap [8] is placed previous position, holding air bag [5] pressurizes to infusion bottle [1], Pressure gauge [4] demonstrates pressure value simultaneously, rises when reaching predetermined pressure, and threeway gauge tap [8] is placed a back position, Pressure gauge [4] demonstrates pressure value simultaneously, descend when reaching predetermined pressure, threeway gauge tap [8] is placed previous position, hold air bag [5] and continue pressurization.Like this, promptly can be patient by tube for transfusion [2] infuses fast.For the ease of puncturing to the infusion bottle bottle stopper, the upper end of air inlet pipe [3] is the angle shape.

Claims

1, a kind of controlled supercharger of quick transfusion that is used to patient infusion, medicinal liquid transfers to patient through tube for transfusion [2], it is characterized in that: air bag [5] is connected with air inlet pipe [3] and Pressure gauge [4] respectively by tee T [7] and connection tube [6].

2, the controlled supercharger of quick transfusion as claimed in claim 1 is characterized in that: also be provided with threeway gauge tap [8] on tee T [7].

3, the controlled supercharger of quick transfusion as claimed in claim 1, it is characterized in that: the upper end of air inlet pipe [3] is the angle shape.
