Abstract
The utility model discloses a medical device, particularly discloses an air charging device of a deposable transfusion system. The air charging device of a deposable transfusion system comprises an air charging pipe and an air inlet positioned at the top end of the tail end thereof, and is characterized in that the tail end of the air charging pipe is connected with a blocking valve through a connecting pipe, and the blocking valve is matched with the air inlet. Because the blocking valve is added on the air charging pipe, when the pressure in a liquid bottle is increased, and liquid medicine flows out, the blocking valve is closed; when the liquid in the bottle causes negative pressure not to flow smoothly, the blocking valve is opened, air enters the bottle, so the operation is convenient, and the liquid medicine can not be polluted. The utility model solves the problem of medication safety of a transfusion system and has the advantages of convenient operation, safety and sanitation.
Description
(1) technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of Disposable air-intake installation of infusion device.
(2) background technology
The shortcoming that the transfusion device that we use now exists: because in infusion process, behind patient's dosing obtaining liq, liquid internal pressure power increases, in time gas is not extracted out, when causing transfusion, liquid flows out from air inlet, promptly waste medicinal liquid, polluted the drug safety that incompatibility is present again easily.
(3) summary of the invention
This utility model provides a kind of easy to operate, free of contamination Disposable air-intake installation of infusion device in order to remedy the deficiencies in the prior art.
This utility model is achieved by the following technical solution:
A kind of Disposable air-intake installation of infusion device comprises air inlet pipe and is positioned at the vertical air inlet of its afterbody that its special character is: the end of described air inlet pipe is connected with the obstruction valve that matches with air inlet by connecting band.
This utility model adds one and stops up valve on air inlet pipe, when the increase of liquid bottles internal pressure, when medicinal liquid flows out, close the obstruction valve, liquid causes negative pressure in bottle, when circulation is not smooth, to stop up valve open, and make in the air admission medicine bottle, be that handled easily does not pollute again like this.
This utility model has solved transfusion device drug safety problem, has advantages easy to operate, safety and sanitation.
(4) description of drawings
Below in conjunction with accompanying drawing this utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1 air inlet pipe, 2 air inlets, 3 connecting bands, 4 stop up valve.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises air inlet pipe 1 and is positioned at the vertical air inlet 2 of its afterbody that the end of air inlet pipe 1 is connected with the obstruction valve 4 that matches with air inlet 2 by connecting band 3.This product adds one and stops up valve 4 on air inlet pipe 1, when the increase of liquid bottles internal pressure, when medicinal liquid flows out, close and stop up valve 4, liquid causes negative pressure in bottle, when circulation is not smooth, to stop up valve 4 and open, and make in the air admission medicine bottle, be that handled easily does not pollute again like this.
Claims (1)
1. a Disposable air-intake installation of infusion device comprises air inlet pipe (1) and is positioned at the vertical air inlet of its afterbody (2), it is characterized in that: the end of described air inlet pipe (1) is connected with the obstruction valve (4) that matches with air inlet (2) by connecting band (3).
