Inhalation anesthetic in use inevitably will be revealed in atmosphere, for the healthy generation harm of the exposed population group in environment, is the staff who makes us problem, the especially operating room of care, can occur hypomnesis, headache, the symptoms such as dizziness.According to U.S. anesthesiology doctor, learn investigation, the risk that is exposed to Natural Abortion, tumor, hepatic disease and the kidney disease of high concentration waste gas of anesthesia raises, its offspring's increased risk in congenital malformation.The male doctor's hepatic disease increased risk that is exposed to high concentration waste gas of anesthesia, the risk of its children's congenital malformation also increases.External some national regulation waste gas of anesthesia safe level, China is not at present about the relevant regulations standard of waste gas of anesthesia.For operation room work personnel's health, the discharge of waste gas of anesthesia has been studied to a lot of methods, but the whole bag of tricks cuts both ways, what have is expensive, and some waste gas is discharged not exclusively, and to medical worker and patient, all there is great risk in what have.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned problems of the prior art, and a kind of open gas cells buffer-type anaesthesia exhaust gas cleaning device is provided.
This utility model is achieved by the following technical solution:
A kind of open gas cells buffer-type anaesthesia exhaust gas cleaning device, comprise shell and be fixed on the inner shell in shell, shell forms (i.e. a closed box) by top board, base plate, front side board, back side panel, left plate and right plate, and inner shell is comprised of the second top board, the second left plate and the second right plate, the front-end and back-end of the second top board of inner shell are individually fixed on the front side board and back side panel of shell, the front end of the second left plate of inner shell, rear end and bottom are individually fixed in the front side board of shell, on back side panel and base plate, the left end of the top of the second left plate of inner shell and the second top board of inner shell is fixed, the front end of the second right plate of inner shell, rear end and bottom are individually fixed in the front side board of shell, on back side panel and base plate, the right-hand member of the top of the second right plate of inner shell and the second top board of inner shell is fixed, between shell shell wall and inner shell shell wall, formed the n shape cavity (that is: the interlayer between shell shell wall and inner shell shell wall is the cavity of a n shape) of sealing, between shell shell wall and inner shell shell wall, be fixed with n shape dividing plate, n shape dividing plate is divided into front n shape cavity and rear n shape cavity by n shape cavity, and (n shape dividing plate just in time connects and fixes in n shape cavity, each limit of n shape dividing plate respectively with top board, left plate, the right plate of shell, the second top board of inner shell, the second left plate, the second right plate are fixed), between the He You bottom, left bottom of n shape dividing plate and the base plate of shell, all leave gap (being communicated with between front n shape cavity and rear n shape cavity bottom realized in this gap), the top board of shell is provided with exhaust gas entrance pipeline, the horizontal chamber, top of front n shape cavity is passed, extend the inside (n shape cavity is divided into the perpendicular chamber on the horizontal chamber at top, the perpendicular chamber in left side and right side) of inner shell after the second top board of inner shell in the bottom of exhaust gas entrance pipeline, the position that is positioned at the horizontal intracavity in front n shape cavity top on exhaust gas entrance pipeline offers gas outlet, on the bottom port of exhaust gas entrance pipeline, be connected with buffer air bag, buffer air bag is placed in inner shell inside, the position that is positioned at discarded inlet duct left side on the top board of shell offers communicate with the horizontal chamber, top of front n shape cavity uncovered, and the horizontal intracavity in top of front n shape cavity exhaust gas entrance pipeline and uncovered between position be provided with baffle plate and cut off, the right plate of shell is provided with the vacuum suction pipeline communicating with the perpendicular chamber, right side of front n shape cavity, on vacuum suction pipeline, valve is installed.
During use, the waste gas outlet of anesthetic machine is connected on the exhaust gas entrance pipeline of this utility model device, the vacuum suction pipeline on this utility model is connect to vacuum suction instrument.Operation is when carry out, and the waste gas of discharging from anesthetic machine is entered by exhaust gas entrance pipeline, and discharge waste gas gas outlet from exhaust gas entrance pipeline under vacuum suction, and attracted in vacuum suction pipeline and discharge.If the exhausted air quantity of discharging from anesthetic machine is excessive, this utility model has twice buffer area: wherein a part of waste gas enters into air bag and cushions, and the elastical retraction by air bag progressively attracts to discharge from gas outlet by vacuum suction pipeline again; The buffering route of a part of waste gas is in addition: the perpendicular chamber → uncovered discharge (being that forward and backward n shape cavity is just equivalent to a buffer channel) in left side of the perpendicular chamber → gap → front n shape cavity in left side of horizontal chamber, the top → rear n shape cavity of the perpendicular chamber → rear n shape cavity in right side of the perpendicular chamber → gap → rear n shape cavity in right side of the horizontal chamber, top of exhaust gas entrance pipeline → gas outlet → front n shape cavity → front n shape cavity, through this road buffering, final almost nil from the waste gas of uncovered discharge.
In addition, through test of many times, show, when negative pressure is 0.04-during 0.07mpa, the waste gas of anesthesia discharge rate of this utility model device can reach 100%.
Further, the gas outlet on exhaust gas entrance pipeline is over against the right plate of shell
offer(negative pressure opening), the vacuum suction pipeline on shell right plate arranges over against the gas outlet on exhaust gas entrance pipeline.The discharge that is arranged so that like this waste gas is more direct, and expulsion efficiency is higher.
On vacuum suction pipeline, by-pass valve control is installed, is easy to control the aperture size of vacuum suction pipeline.
The beneficial effects of the utility model are as follows:
1) safe and effective, design ingeniously, rational in infrastructure, make easily, easy to maintenance;
2) be provided with air bag buffer area and forward and backward n shape cavity buffer channel, to a large amount of aerofluxuss of moment, can play the effect of buffering, reduced the excessive of waste gas, make the discharge of waste gas more thorough, greatly improved the discharge rate of waste gas;
3) symptoms such as the waste air effect of this utility model device is splendid, substantially leaks without waste gas, and staff often had a headache originally, dizzy and sleepy, are used after this device no one again that above symptom occurs;
4) this utility model device is open (being provided with uncovered), safe, can not cause causing because vacuum suction is excessive the problem that anesthetic machine pressure limiting valve is malfunctioning.In addition, even if negative pressure is not opened, can not cause damage to patient, yet.
