Description
Technical field
The present invention relates to field of medical device, and in particular to a kind of Medical anesthetic waste gas reception device.
Background technology
The invention of Inhalation Anesthetic indicates the birth of modern anaesthesia, it greatly promoted modern medicine progress and
The raising of civilization of human society degree.Inhalation anesthetic is used except anesthesia, how always whether has harm or its degree to human body
It is to make us concern, continuous renewal is experienced for this inhalation anesthesia.
But inhalation anesthesia gas is inevitably ultimately discharged into air in anaesthesia process.Inevitable property is embodied in
Metabolism amount of these gases in human body is seldom, and patient is regained one's consciousness after being anaesthetized to depend finally on and all breathed out with original shape by breathing,
Arrange to air.In addition, in inhalation anesthesia implementation process, more or less always there is part anesthetic gases leakage, in existing technology
Under the conditions of, this leakage can not be prevented, at present, the most important source of anesthetic gases is the waste gas of Anesthesia machine discharge in operating room.
Because anesthetic gases has mutagenesis type, carcinogenicity and organ toxicity, reproductive function can also be had an impact, so useless to anaesthetizing
The absorption of gas is particularly subject to anesthetist, theatre sister, numb recovery room and the concern of ICU medical personnel, at present there is an urgent need to
A kind of device received to waste gas of anesthesia.
The content of the invention
(1) technical problem solved
In view of the shortcomings of the prior art, the invention provides a kind of Medical anesthetic waste gas reception device, having can be to fiber crops
The advantages of liquor-saturated waste gas is safely and effectively received.
(2) technical scheme
To realize object above, the present invention is achieved by the following technical programs：
A kind of Medical anesthetic waste gas reception device, including central negative pressure device, air inlet pipe and air bag, the air inlet pipe lower end
It is connected with connecting tube, the connecting tube left end is connected with left branch pipe upper end, the left branch pipe lower end and the central negative pressure
Device is connected, and the connecting tube right-hand member is connected with the right branch pipe, and the right branch pipe is provided with going out gas branch pipe, the right branch
Pipe lower end is provided with circular piece, and the circular piece is provided with stomata, flap valve, pipeline and the air bag phase are provided with above the circular piece
Connection, the lower end of duct are located in detector, and the lower end of duct is provided with plug, and sliding shoe is provided with the pipeline, described
Plug is connected with the sliding shoe by spring, and the pipeline right-hand member is provided with gas outlet.
Further, the right branch pipe runs through the air bag, and the right branch pipe lower end is communicated with the outside.
Further, the going out gas branch pipe is located in the air bag.
Further, the flap valve is circle.
Further, the radius of the flap valve is more than the radius of the stomata and less than the radius of the right branch pipe.
Further, the gas outlet is identical with the slip tile height.
Further, the plug is fixedly connected with the pipeline, and the plug shuts the lower end of duct.
(3) beneficial effect
The invention provides a kind of Medical anesthetic waste gas reception device, waste gas can pass through laboratory caused by general Anesthesia machine
In central negative pressure device take away, but because the central negative pressure device in laboratory often also needs to external other instruments, when
When other instruments are vented to center negative pressure device, waste gas of anesthesia, which cannot discharge, to be leaked into operating room, and of the invention
In run into such case waste gas of anesthesia can enter air bag in, when the waste gas of anesthesia stored in air bag is excessive, air pressure can squeeze downwards
Pressing spring, sliding shoe slide downward, expose gas outlet, waste gas of anesthesia overflows into detector, and medical personnel can pass through detection
Device has learnt anesthetic gases leakage, in addition when center negative pressure device negative pressure is excessive, each circuit pressure of Anesthesia machine can be balanced and produced
It is raw to influence, Anesthesia machine can be caused to alarm when serious, if central negative pressure device negative pressure is excessive in the present invention, air bag shrinks, internal
Air pressure reduces, and the flap valve in right branch pipe is heaved by ambient pressure, and air enters from stomata, ensures that each circuit pressure of Anesthesia machine is put down
Weighing apparatus, so the present invention has the advantages of can safely and effectively being received to waste gas of anesthesia.
