Abstract
The utility model relates to a medical appliance, in particular to a closed infusion apparatus, namely a closed infusion apparatus. The closed infusion device consists of plug, liquid pipe, ventilating pipe interface, air valve, air tank and needle. The technical scheme of the utility model is that: the medical sterile gas is filled into a sealed container, namely a gas tank (consisting of a gas valve and a gas tank body). The upper part of the air tank is provided with an air valve, the mouth part of the air valve is connected with a vent pipe of the infusion apparatus, and the air in the air pipe can be controlled to enter the infusion bottle by adjusting the air valve, so that the sterile air in the air tank replaces the air in the atmosphere.
Description
Affiliated technical field
This utility model relates to a kind of medical apparatus, especially a kind of case type transfusion device.
Background technology
At present, transfusion is a kind of Therapeutic Method commonly used, in order to guard against cross infection etc., at present adopts " disposable transfusion devices " to carry out more.Transfusing container port is inserted with two hollow pipes, and one by all means as the passage of liquid from the container to the human body; Another then is a breather by all means, and its other end is an open state, directly communicates with outside air, thereby import air in infusion vessel, to finish transfusion.Although through sterilization, still exist various types of pathogenic bacterias in the air, very likely bring harmful effect to treatment.
Summary of the invention
In order to overcome the deficiency of existing infusion model, the purpose of this utility model just provides a cover solution: a kind of safe, inexpensive, aseptic transfusion apparatus---enclosed type transfusion device.
To achieve these goals, this utility model solves the technical scheme that its technical problem adopts and is: medical aseptic gas is charged into a sealed container---gas tank (forming) by the gentle tank body of air valve.Gas tank can be an arbitrary shape, cylindrical, sphere etc., but must seal, air valve is equipped with on gas tank top, the air valve mouth is connected with the breather of transfusion device, by regulating air valve, can control the gas tank gas inside and enter infusion bottle, thereby the aseptic gas in the gas tank replaces the air in the atmosphere.
The beneficial effects of the utility model are, when adopting this utility model apparatus to infuse, fully and isolate from outer air, have stopped entering and injuring of pathogenic bacteria in the air.In addition, can select to charge into the gas in the gas tank, as oxygen etc., the liquid in the infusion bottle can dissolve more oxygen to be brought in the body, is beneficial to the treatment of the state of an illness more.

The specific embodiment
In Fig. 1, by plug (1), fluid-through tube (2), breather (3), breather interface (4), air valve (5), gas tank body (6), syringe needle (7) are formed jointly " enclosed type transfusion device ".
Plug (1) bottom is connected with fluid-through tube (2), breather (3), and fluid-through tube (2) bottom is connected with syringe needle (7), and breather interface (4) is connected with air valve (5), and air valve (5) is connected with gas tank body (6).
During use, " enclosed type transfusion device " connection is complete, plug (1) head is inserted in the rubber lid of transfusion, transfusion bottle, regulate air valve (5) then, gas enters in transfusion, the transfusion bottle by breather (3), thereby finishes aseptic medical gas substituting air.
In Fig. 2, breather interface (8) is connected threadably with the air valve (9) of gas tank.It is the same with aforementioned process when using.
In Fig. 3, breather interface (10) diameter directly inserts air valve less than mouth (11) the blank pipe diameter of gas tank air valve, finishes connection.It is the same with aforementioned process when using.
In Fig. 4, breather interface (12) diameter is greater than mouth (13) diameter of gas tank air valve, and the mouth of air valve (13) directly inserts breather interface (12), finishes connection.It is the same with aforementioned process when using.
In Fig. 5, breather interface (14) is connected with elastic tube (16) with the mouth (15) of gas tank air valve.It is the same with aforementioned process when using.
Claims (7)
