Abstract

The invention relates to a medical infusion apparatus. Compared with the conventional infusion apparatus which adopts the pressure of the liquid for performing infusion operation, and the pressure of the gas is adopted by the mobile infusion apparatus for infusion. A patient can move freely (indoors and outdoors) while an infusion bottle is not hung and body posture of the patient is not restricted, suitable pressure is obtained through holding mode to a leather bag by hands via the manual work, the mobile infusion apparatus is conveniently used in hospitals, field, in the disaster areas and other places for rescue.

Description

Moved transfusion system

Technical field

This invention relates to a kind of medical Transfusion device.

Background technology

Infusing when Medical being treated patient and become requisite mode, is also main drug injection mode.The utensil used in infusion process mainly contains, drip stand, infusion bottle, tube for transfusion etc., uses this kind of compound mode transfusion patient cannot be movable freely, or movable according to the practical situation of patient.Especially when infusing, because a large amount of liquid infusions enters human body, patient just can produce a large amount of urine, so, patient is just by the needs of going to toilet, drip stand fixing in this case uses just inconvenient, and many times patient can only go to toilet under other people help, if patient and caretaker's different sexes are just difficult to when going to toilet carry out; If do not have other people to help, most patient can only suppress urine, and this is just difficult to be subject to; Also have when there is seasonal influenza, the quantity of sufferer will sharply increase, bring huge pressure, in addition, when occurring the condition of a disaster at short notice limited medical resource, fixing drip stand cannot be delivered to substantially timely, also cannot using simultaneously, also having the existing drip stand when there is field rescue cannot use, based on above all inconvenience, spy makes this invention, in the hope of solving existing inconvenience to a greater extent.

Summary of the invention

This invention relate to this transfusion device of a kind of medical Transfusion device by frame, be linked with, be linked with bolt, transfusion bottle (bag), check valve, airstrainer, pressurization leather bag, tube for transfusion, the institute such as Bidirectional stop inverse valve of floating form (referring to Figure of description), this invention does not need patient to be limited to same position in use, patient can be freely movable according to own situation, not necessarily berth will be taken, especially the patient that the state of an illness is lighter, can more effectively utilize limited medical resource like this, for more people benefits.

Mainly tube for transfusion is described at this, this tube for transfusion is made up of objects such as high-pressure pipe and two-way floating check (non-return) valves, high-pressure pipe mainly provides air pressure to enter human body to make medicinal liquid, and two-way floating check (non-return) valve, prevent blood backflow and gases at high pressure from entering human body, this valve only agrees liquid to enter human body, does not agree gas to enter, so ensure that the order of infusion process, stationarity, safety and mobility.

。

Claims

1. this invention relate to this transfusion device of a kind of medical Transfusion device by frame, be linked with, be linked with bolt, transfusion bottle (bag), check valve, airstrainer, pressurization leather bag, tube for transfusion, the institute such as Bidirectional stop inverse valve of floating form (referring to Figure of description), this invention does not need patient to be limited to same position in use, patient can be freely movable according to own situation, not necessarily berth will be taken, especially the patient that the state of an illness is lighter, can more effectively utilize limited medical resource like this, for more people benefits.

2. tube for transfusion, this tube for transfusion is made up of objects such as high-pressure pipe and two-way floating check (non-return) valves, high-pressure pipe mainly provides air pressure to enter human body to make medicinal liquid, and two-way floating check (non-return) valve, prevent blood backflow and gases at high pressure from entering human body, this valve only agrees liquid to enter human body, does not agree gas to enter, so ensure that the order of infusion process, stationarity, safety and mobility.

3. when medicinal liquid is about to be totally lost, lower end medicine liquid outlet blocked by check ball, enters human body to prevent gases at high pressure; And the blood of human body backflow when the blood pressure of human body is greater than the pressure of gases at high pressure, medicinal liquid face raises reverse stopping ball and together raises with liquid level, blocks upper end medicinal liquid entrance, and limit blood outflows, to reach the object of Bidirectional stop inverse flowing.

4. two-way floating check (non-return) valve controls liquid and enters human body, and restriction gas enters human body, with the blood backflow of limit human body.

5. the operation principle of two-way floating check (non-return) valve is as figure below: check (non-return) valve needs to place in vertical in use, with ensure reverse stopping ball can with liquid level move up and down and float, when exporting under liquid level decline is about to arrival, reverse stopping ball has most of volume submerged before this, and more than liquid level have air pressure now reverse stopping ball block lower outlet, the effect now infusion-completed play current limliting, damming; When the air pressure in infusion-completed transfusion bottle may be less than human blood-pressure, blood backflow also rises with liquid level to check (non-return) valve during upper inlet together when blood backflow, the effect that upper inlet plays reverse flow limiting, dams blocked by check (non-return) valve, thus realizes the function of the non-return flowing of two-way floating.

6. the signal of two-way floating check valve structure is as shown in Figure of description 2.

7. reverse stopping ball specific density (weight is divided by volume) ρ=m ÷ v (m is weight, the volume of v included by reverse stopping ball surface area), the span of ρ is: 0.7(grams per milliliter)≤ρ < 1 (grams per milliliter).
