Abstract
The invention discloses a medical device, especially discloses the air inlet device of a disposable infusion device. The air inlet device of the disposable infusion device includes an air inlet pipe and an air inlet hole which is arranged on the top end of the tail part of the air inlet pipe, and is characterized in that the tail end of the air inlet pipe is connected with a blocking valve which is matched with the air inlet hole by a connecting band. The invention adds the blocking valve on the air inlet pipe. When the pressure in a liquid bottle increases and the medical solution flows out, the blocking valve is enclosed. When negative pressure is made by the liquid in the bottle and the circulation is weak, the blocking valve is opened and air enters into the medical bottle. Therefore, the operation is convenient and no pollution is made. The medical device solves the medical safety problem of the infusion device and has the advantages of convenient operation, safety and health.
Description
(1) technical field
The present invention 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
The present invention 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.
The present invention is achieved through the following technical solutions:
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.
The present invention 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.
The invention solves transfusion device drug safety problem, have advantages easy to operate, safety and sanitation.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present invention.
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 invention.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).
