Abstract
A negative pressure suction type anesthetic exhaust gas discharger is in a cuboid shape; the side of the discharger is provided with a connecting pipe; an outer opening is used to connect the exhaust gas discharge pipe of an anesthesia machine; an inner opening is provided with a soft rubber open bush; and two connectors are arranged above the open bush, wherein one connector is connected with a central negative pressure extractor and the other connector is an air inlet. The exhaust gas discharge pipe of the anesthesia machine is connected into the negative pressure suction type anesthetic exhaust gas discharger, the anesthetic exhaust gas is completely sucked out through negative pressure suction; and air is added from the air inlet of the negative pressure suction type anesthetic exhaust gas discharger, thus the inside of the anesthetic exhaust gas discharger does not have larger negative pressure.
Description
One, affiliated technical field
The present invention relates to a kind of anesthesia gas emission device, especially the tail gas of gas anesthesia agent can be discharged fully, the contaminated operation room environmental is not reduced expenses, and the non-once sex aids help environmental protection.
Two, background technology
At present, the discharge of gas anesthesia agent mainly contains three kinds of modes, and the one, directly drain into operating room, no laminar flow in the operating room, the gas anesthesia agent is accumulated in the operating room; The 2nd, directly be emitted in the streamlined operating room, can take away anesthesia tail gas by laminar flow; The 3rd, with special adsorbent anesthesia tail gas is adsorbed to fall.First kind of mode can make anesthetis accumulate in a large number in the operating room, and contaminated environment has harm such as the interior medical worker's headache of the operating room of making, teratogenesis, has greatly hindered to suck narcotic application; Second way operating cost is big, and can not guarantee not have anesthesia tail gas in the operating room environment certainly, and effect is also imprecise; The third mode makes cost of anesthesia increase hundreds of units, and anesthesia tail gas adsorbent equipment is disposable use, increases the weight of environmental pressure.Negative pressure attraction type anesthesia exhaust emissions device then has makes tail gas discharge and don't cause advantages such as patient's financial burden, environmental protection fully.
Three, summary of the invention
The technical problem to be solved in the present invention is: discharge fully in order to make anesthesia tail gas, do not increase patient's financial burden again, the use of product non-once does not increase environmental pressure, therefore we invent directly the anesthesia exhaust emissions is gone in the fixed container, again by continuous negative pressure suction, all anesthesia tail gas are discharged, can not pollute fully operating room environment.
The technical scheme that technical solution problem of the present invention is adopted is: a kind of negative pressure attraction type anesthesia exhaust emissions device, profile is a cuboid, there is an adapter side, collar extension is used to connect the anesthetic machine tail gas discharging pipe, internal orifice has a soft rubber opening sleeve, it is to connect central negative pressure to attract that there are two interfaces, the interface in top in the top, and another opening of top is an air inlet.The anesthetic machine tail gas discharging pipe is inserted in the fixed container, end at delivery pipe connects a soft rubber opening sleeve, closes substantially at ordinary times, when the anesthesia exhaust emissions, light pressure in the pipeline can strut soft rubber automatically, guarantees anesthesia tail gas one-way flow.Open one big (diameter is 3cm), two holes of one little (connecing vacuum extractor) above container, aperture connects central negative pressure and attracts, and macropore is used to into air.When not having the anesthesia exhaust emissions, be lower negative pressure substantially in the container, the rubber opening sleeve is closed automatically, can not damage anesthetic machine.When exhaust emissions, when forming air pressure slightly in the exhaust pipe, will open the air inlet in the exhaust emissions device of rubber opening sleeve automatically, be sucked away continuously subsequently.During anesthesia since oxygen flow below 10 liters/minute, the speed that continues central vacuum suction can reach the 20-50 liter/minute, therefore the tail gas that can guarantee to enter negative pressure attraction type anesthesia exhaust emissions device can not make in the exhaust emissions device and malleation occur, the unidirectional all the time opening of air inlet does not have anesthesia tail gas and enters in the operating room and pollute.
The invention has the beneficial effects as follows, can in whole anesthesia process, directly discharge anesthesia tail gas that do not pollute the environment, simple in structure, environmental protection does not increase operating cost and patient's financial burden.
Four, description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is an exhaust emissions schematic diagram of the present invention.
1. air inlets among the figure, 2. central negative pressure attracts interface, 3. anesthetic machine exhaust emissions interface tube, 4. soft rubber opening sleeve.
Five, the specific embodiment
In Fig. 1, anaesthetize preceding 4 rubber opening sleeves and close, after anesthetic machine is opened, the speed of anesthesia exhaust emissions equals oxygen flow, tail gas is discharged in 3 tail gas discharging pipes, and pressure can be opened 4 rubber opening sleeves automatically slightly, enters in the negative pressure attraction type anesthesia exhaust emissions device.2 central negative pressures attract sustainable the making in the negative pressure attraction type anesthesia exhaust emissions device of seam continuous negative pressure suction to be lower negative pressure, and 1 air inlet goes out air to be continued to enter, and remedies the amount of anesthesia tail gas, forms the throughput of vacuum suction jointly.The throughput of vacuum suction is fixed, and anesthetic machine exhaust emissions amount equals the oxygen flow of anesthetic machine, and the amount of air inlet then can along with how many adjustment automatically of tail gas amount.Not during last person's gas, the vacuum suction sucking-off be air fully, when the exhaust emissions amount was big, air was just less slightly.
Claims (1)
1. a negative pressure attraction type is anaesthetized the exhaust emissions device, profile is a cuboid, there is an adapter side, collar extension is used to connect the anesthetic machine tail gas discharging pipe, internal orifice has a soft rubber opening sleeve, it is to connect central negative pressure to attract that there are two interfaces, the interface in top in the top, and another opening of top is an air inlet.
