Abstract

The utility model provides a negative pressure suction type anesthetic tail gas discharge device, which takes the shape of a cuboid. An interface is arranged on one lateral surface of the cuboid, the outer part of the cuboid is used for connecting with a tail gas discharge pipe and is provided with a soft rubber opening sleeve; and two interfaces are arranged on the upper surface of the cuboid, wherein one interface is connected with a central negative pressure suction interface, and the other interface serves as an air inlet. The utility model adopts the technical scheme that the tail gas discharge pipe of the anesthesia machine is connected with the negative pressure suction type anesthetic tail gas discharge device; anesthetic tail gas is completely sucked out through negative pressure suction interface; air for compensation enters through the air inlet of the negative pressure suction type anesthetic tail gas discharge device, so that stronger negative pressure can not be formed in the negative pressure suction type anesthetic tail gas discharge device.

Description

Negative pressure attraction type anesthesia exhaust emissions device

One, affiliated technical field

This utility model relates to a kind of anesthesia gas emission device, especially the tail gas of gas anesthesia agent can be discharged fully, and 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

[summary of the invention: should comprise utility model technical problem to be solved, solve technical scheme and beneficial effect thereof that its technical problem adopts.]

The technical problems to be solved in the utility model 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 this utility model technical solution problem is adopted is: a kind of negative pressure attraction type anesthesia exhaust emissions device, profile is a cuboid, there is an interface side, the outside is used to connect the anesthetic machine tail gas discharging pipe, have 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 beneficial effects of the utility model are, can directly discharge anesthesia tail gas in whole anesthesia process, do not pollute the environment, and simple in structure, environmental protection does not increase operating cost and patient's financial burden.

Four, description of drawings

Below in conjunction with drawings and Examples this utility model is further specified.

Fig. 1 is an exhaust emissions schematic diagram of the present utility model.

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. a negative pressure attraction type is anaesthetized the exhaust emissions device, and profile is a cuboid, and there is an interface side, the outside is used to connect the anesthetic machine tail gas discharging pipe, has a soft rubber opening sleeve, and there are two interfaces the top, the interface in top is to connect central negative pressure to attract, and another opening of top is an air inlet.
