Abstract
The present invention discloses an aseptic inflation bag which is a new medical utensil. Especially in a transfusion course, the aseptic inflation bag can cause the gas pressure in a transfusion bottle to be kept balanced to form a self-regulation phenomenon. The aseptic inflation bag is composed of an exhaust opening, a needle body, a handle, an opening valve, a gas bag, etc. The product of the present invention is suitable for various occasions and has the characteristics of safety, reliability, convenient use, easy operation, no need of special management, etc.
Description
Technical field
The present invention relates to a kind of medical apparatus, particularly a kind of aseptic inflation bag that in infusion process, uses.
Background technology
Transfusion is hospital's a kind of therapy for the treatment of disease commonly used, infects for the air pollution and the crossings on different level that reduce in the transfusion, and some places have adopted bacteria-free oxygenator to infuse.
But, using bacteria-free oxygenator to carry out in the infusion process, often because air pressure is excessive in the bottle, makes often to can not get effective control in the exhaust process, thereby cause the anxious phenomenon of wearing of liquid.
Publication number is that the Chinese invention patent application of CN1391958A discloses a kind of sterile pure net air infusion techn that utilizes, its employed equipment comprises drip stand, medicinal liquid bottle, mesh bag, transfusion device and airbag, treated sterile pure net air is housed in the airbag, one flow control valve is arranged on the escape pipe of airbag, during use, the mouth of pipe of giving vent to anger is connected on the air inlet of the transfusion device mouth of pipe, also has a prelum on the airbag, act on the airbag wall.The technical scheme that proposes in the disclosure file is, carries purified air by an airbag in infusion bottle, thereby avoids that air inlet on the infusion bottle is directly air-breathing from environment to be entered infusion bottle and cause the problem of cross infection.But also there are following defectives in this technical scheme:
1, the danger of complex structure and existence pollution
In this technical scheme, the escape pipe of airbag is provided with flow control valve, this control valve contacts with external environment, the valve body air inlet of control valve and air vent and airbag escape pipe have two junction points, formed a junction point movingly again between the valve rod that valve body and control valve open and close, above-mentioned junction point structurally needs very high-air-tightness, and its structure must be very meticulous, thus, also will make this technical scheme become complicated.If above-mentioned each junction point is no matter that is poorly sealed, the gas in the airbag will leak, and makes this equipment failure.In addition, the accessory of control valve is more, and making and assembly precision are had relatively high expectations, and sterilization all compares difficulty, like this, though there is contaminated probability in the gas in the airbag through being treated to aseptic gas when gas is flowed through control valve.
2, the syndeton with infusion bottle is unreasonable
In this technical scheme, the escape pipe of airbag is received on the air inlet of transfusion device bottleneck, sees the escape pipe of airbag and medicine liquid outlet pipe and together from accompanying drawing.Under normal conditions, the air inlet of transfusion device bottleneck and medicine liquid outlet are not a mouth, but, in this technical scheme,, do not provide other explanatory note except accompanying drawing, therefore, according to the structural analysis of accompanying drawing, such airbag escape pipe structure, entering of the discharge of medicinal liquid and air is that a mouth by on the bottle cap of infusion bottle is finished.So, the medicinal liquid of discharge may flow in the airbag escape pipe, and the medicinal liquid and the gas in the airbag is rushed to summit may enter in the discharging tube.If this occurs, the gas-entrained danger that enters human body that will occur infusing.Therefore, the unreasonable structure of this technical equipment.
3, complicated operation causes maloperation easily
When this equipment of operation, control valve need be opened, can also press from both sides by adjusting control valve and on airbag and establish clip, the constantly artificial gas atmosphere that in infusion bottle, provides that increases.In operation is exactly cumbersome, also accident may occur simultaneously, and normally air feed just makes medicinal liquid can inject human vein in infusion bottle, when the bottle herb liquid is totally lost, pressure in the transfusion device is less than venous pressure, if in time do not extract entry needle, only blood back can occur.If but adopt artificial intensified pressure, make pressure in the infusion set always greater than the pressure of human vein, be totally lost at medicinal liquid, if in time do not find, just occur gas and enter the big problem that vein forms aeroembolism, serious may crisis life.
Summary of the invention
The objective of the invention is to improve deficiency of the prior art, a kind of simple in structure, safe in utilization, easy and healthy aseptic inflation bag that is used with transfusion device is provided.
The object of the present invention is achieved like this:
A kind of aseptic inflation bag provided by the invention, it is a kind of medical apparatus that can regulate the air pressure air-flow in the medical transfusion process automatically, it is characterized in that, it is made up of air vent, needle body, handle, open valve and airbag five parts, the described needle body of sealing grafting on the described handle upper port, described air vent is arranged on the described needle body, and described handle, at its lower end and described airbag are tightly connected; Described handle, at its lower end is positioned at the airbag gas outlet and has an educible described open valve.During use, described open valve is inferred that gas will be by airbag by discharging the described air vent of handle from needle body.
Aseptic inflation bag provided by the invention is applicable to medical transfusion, medical treatment oxygen therapy.It has safe, reliable, easy to use, cost is low, easy to operate, need not characteristics such as special management, also can be used for the control of other gas.Structure is also fairly simple simultaneously.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of aseptic inflation bag provided by the invention.
The specific embodiment
As shown in Figure 1, a kind of aseptic inflation bag provided by the invention, it is a kind of medical apparatus that can regulate the air pressure air-flow in the medical transfusion process automatically, it is made up of air vent 1, needle body 2, handle 3, open valve 4 and airbag 5 five parts.
During use, in the plug that is needled into infusion bottle on this aseptic inflation bag, open valve 4 is inferred that at this moment, gas will be discharged by outlet 1 by handle 3 by airbag 5, enters in the infusion bottle.What are discharged for gas and to discharge size relevant with the pressure in the infusion bottle, and pressure is little in the bottle, and the aseptic inflation bag expellant gas is just many, the gas pressure in the bottle, all the time with aseptic inflation bag in gas pressure keep balance, form a kind of self regulation phenomenon.
