Description
Technical field
The present invention relates to a kind of medical gas sampling purifier, particularly a kind of waste gas of anesthesia is collected and purifier.
Background technology
Along with gas anesthesia is widely used in all kinds of operations as a kind of effective anesthesia means, waste gas of anesthesia is handled problems and more and more is subjected to people's attention, a large amount of zooperies, epidemiology survey and clinical observation show that all more non-operation room work personnel of the incidence of disease such as operation room work personnel's miscarriage, bone marrow suppression and malignant tumour are high; Anesthesia is polluted and is meant the pollution of volatile anesthetic to operating room air.Generally implementing to suck in the general anesthesia process, adopt open or anesthesia,semiopen method, anesthetic gases directly and room air mix, cause operating room air to pollute, even select semi-closed formula or closing type Anesthesia machine for use, anesthetic gases still can be discharged the contaminated operation environment from face shield, exhaust pition, screwed pipe etc.Obvious different anesthetic and anesthesias, its pollution level has nothing in common with each other, and in same operating room, the degree that anesthesia is polluted is also different everywhere.The highest near near concentration Anesthesia machine and the patient respiration road, so the anesthesia personnel is bigger than operative doctor, the contaminated influence of nurse.Reported literature is arranged, compared the concentration of anesthesia personnel and surgeon's nasal cavity local anesthesia medicine, the two has notable difference, and the high 5-70 of the former the concentration ratio latter doubly.It is only accidental once that patient accepts inhalation anesthetic, and the narcot officer worked in the environment midium or long term of polluting, frequent contact anesthesia gas, thereby, even the anesthesia pollution concentration is low, still can influence healthy.Have the interior recovery room of report operating room, corridor, office, doctors and nurses's rest etc. all can record anesthetic gases again, visible anesthesia is polluted and has been related generally near many places.
Anesthesia is polluted and can be worked the mischief to human body by following approach, (1) the arcotic molecule is to the direct detrimental effect of body cell, arcotic enters and suppresses organism immune response in the human body, and phagocytotic leucocyte and lymphocyte transformation activity are suppressed, and weakens Abwehrkraft des Koepers; (2) in the GENERAL ANESTHETICS suction body, its metabolite directly or indirectly damages body cell.Many data think that the anesthesia pollution can cause operation room work personnel spontaneous current productive rate, sterility and monster incidence to raise, and comparing with control group can be up to 1.3-2.0 doubly.Agnogenic sterility incidence is 12% among the Anesthetist, and control group then is 6%.At the report of the relevant investigation Anesthetist cause of death, lymphatic system is died from discovery and reticuloendothelial system malignant tumour person is higher than control group, and is higher with the leukemic death rate among the women Anesthetist.Many investigation results are thought the morbidity of operation room work personnel cancerous swelling except that outside the Pass having with factors such as work strain, fatigues, may suppress cell with arcotic grows relevant, cell division is slowed down and produce abnormal cleavage substance, influence the synthetic of DNA (DNA) and restrain immunity function in the body.
The existing means of handling above-mentioned waste gas mainly are to utilize the absorption principle of activated carbon, and the adsorption structure that activated carbon is housed on the exhaust outlet of Anesthesia machine carries out collection and purification; The use activated carbon is along with the prolongation of time, and adsorption effect can descend, and can only disposablely use; In addition, owing to utilize the normal pressure of Anesthesia machine steam vent to carry out filtering emission, the delivery pipe internal pressure can increase, and influences the normal operation of Anesthesia machine to a certain extent.
Summary of the invention
The purpose of this invention is to provide a kind of novel waste gas of anesthesia that can effectively overcome the problems referred to above generation collects and purifier automatically, it can remain under the normal pressure and collect, can not influence the operate as normal of Anesthesia machine, collection and purification cost are low, the efficient height almost can be with the waste gas of anesthesia and the patient expired gas sampling purified treatment of the Anesthesia machine waste gas exhaust pipe interior 100% of flowing through.
The object of the present invention is achieved like this: it comprises inlet, outlet and is connected between the two pressure buffer unit, filtration, purification unit and vacuum solenoid, the pressure buffer unit is parallel to the pipeline of air inlet one end, the filtration, purification units in series is on pipeline, and vacuum solenoid is installed in pipeline gas outlet one end; The pressure buffer unit is provided with the construction of switch of control vacuum electromagnetic opening of valves; Pipeline between air inlet and the pressure buffer unit is provided with malleation safety valve and negative pressure relief valve;
In the said structure, the pressure buffer unit adopts the folded airbag cavity configuration, and folded airbag is in a cavity, and cavity wall is provided with and detects the optoelectronic switch that the folded airbag stroke is used for controlling the vacuum electromagnetic opening of valves;
In the said structure, the pressure buffer unit adopts the swelling gasbag cavity configuration, it comprises swelling gasbag, swelling gasbag one side is provided with plate washer, opposite side is provided with the removable cover that the upper end is rotationally connected and can swings in vertical direction, the long-armed opposite side that slides on removable cover of contact switch of control vacuum electromagnetic opening of valves;
In the said structure, the filtration, purification unit adopts the liquid cleaner structure, and it is the cavity of a sealing, is loaded with anesthetic gases dissolving liquid, and the air inlet of pipeline stretches into liquid level, on the liquid level of position, gas outlet.
Use when of the present invention, air inlet is linked to each other with the Anesthesia machine outlet port, the gas outlet is connected with the negative pressure of vacuum source; When waste gas of anesthesia produces for a long time, pressure buffer arrangement works (folded airbag elongation or swelling gasbag become big), the construction of switch closure makes the vacuum solenoid unlatching that powers on it on, waste gas of anesthesia just can be by direct sucking-off under the negative pressure of vacuum source acts on; After waste gas of anesthesia is by a large amount of the discharge, loine pressure diminishes, pressure buffer arrangement works (folded airbag shorten or swelling gasbag diminish), and construction of switch is opened vacuum solenoid and is cut off the power supply and close it on, the negative pressure of vacuum source is cut off, to guarantee the relatively stable of pipeline air pressure; In the collection process, waste gas of anesthesia is through the filtration, purification unit time, and the anesthetic gases composition is fully absorbed, thereby reaches the purification requirement of environmental protection, can not produce harmful effect to environment and health; The positive negative pressure relief valve that is installed in the air inlet end can make gas circuit and atmosphere conducting when the vacuum solenoid operational failure, thereby avoids stopping to collect and too collecting the generation of phenomenon, guarantees the personal safety in the medical procedure.
