The specific embodiment
Below in conjunction with accompanying drawing emission-control equipment of the present invention is described in further detail.
As shown in Figure 1, emission-control equipment of the present invention comprises: emission-control equipment of the present invention comprises: shell 1; Waste gas container 2, waste gas container 2 are arranged in the shell 1, are provided with container waste gas of anesthesia import 3 and container waste gas of anesthesia outlet 4 in the bottom of waste gas container 2; Pressure modular converter, pressure modular converter are arranged in the shell 1, and the pressure modular converter be connected 4 by container waste gas of anesthesia import 3 and is connected with appearance waste gas container 2 with the container waste gas of anesthesia; Effusion meter module, effusion meter module are arranged in the shell 1, and the effusion meter module is connected with the pressure modular converter.
The pressure modular converter comprises module base 5, module air chamber 6, module loam cake 7, positive pressuring film plate 8, negative pressure diaphragm 9, malleation valve gap 10 and the negative pressure valve gap 11 that mutually connects successively.Positive pressuring film plate 8 and negative pressure diaphragm 9 are column type, and positive pressuring film plate 8 materials are copper, and negative pressure film sheet material is aluminum.The effusion meter module comprises effusion meter main body 12 and flow control valve 13.Module base 5 is divided into the side that the first air chamber 17, the second air chamber 18 and the 3rd air chamber 19, the first air chambers 17 are arranged on module base 5; The second air chamber 18 and the 3rd air chamber 19 are set in parallel in an other side of module base 5; The first air chamber 17, the second air chamber 18 and the 3rd air chamber 19 are interconnected by pore.The outside of module base 5 also comprises: the module waste gas of anesthesia advance 14 and the module waste gas of anesthesia go out 15, the module waste gas of anesthesia advance 14 and module waste gas of anesthesia outlet 15 be communicated with negative pressure system; Interface 16, effusion meter main body 12 and flow control valve 13 are connected in series with module base 5 by interface 16.
During work, waste gas of anesthesia enters exhaust device by module waste gas of anesthesia import 14, enters the pressure modular converter, and in the air chamber that module waste gas of anesthesia import 14 is communicated with the malleation relief valve is installed, and the diaphragm controlled pressure of malleation relief valve is 10cmH
2O, waste gas enters in the container by the rear port of this air chamber again, enter the waste gas process buffering in the container, under the effect of negative pressure system, by the outlet of the container waste gas of anesthesia in the container 4 out, enter the pressure modular converter, the pressure modular converter is divided into three parts again: module base 5 right sides are divided into two parts, the air chamber on module air chamber 6 right sides.This three parts air chamber communicates by the hole, waste gas by the time negative pressure diaphragm formed certain back pressure.Module base 5 right side two parts respectively have interface 16, and for being connected in series effusion meter in gas circuit, effusion meter is divided into two parts: effusion meter main body 12 and flow control valve 13, discharge by module waste gas of anesthesia outlet 15 at last, and enter negative pressure system and concentrate purification.
As shown in Figure 2, be the duty of emission-control equipment when negative pressure system extraction flow is excessive.Because it is excessive to extract flow, when waste gas of anesthesia entered into the pressure conversion module from the waste gas container, the back pressure on the negative pressure diaphragm was less than-0.3cmH
2O, negative pressure valve is opened, and air enters rapidly the negative pressure of eliminating in the gas circuit.Guarantee the anesthetic machine normal operation.
Duty when as shown in Figure 3, to be emission-control equipment have plugging fault in negative pressure system extracts the too small or pipeline of flow.Because it is too small to extract flow, the pressure rise in the exhaust device gas circuit, waste gas of anesthesia enters the pressure conversion module by module waste gas of anesthesia import 14, when pressure reaches 10cmH
2During O, the positive valve diaphragm is opened, and waste gas enters atmosphere by the hole on the malleation valve gap 10.Excess pressure in the cancellation element is guaranteed the normal operation of anesthetic machine.
The waste gas that anesthetic machine is discharged is collected and cushioned to emission-control equipment of the present invention, and the operating pressure of anesthetic machine is not affected, and purified the working environment of operating room, guaranteed the safety of medical personnel's working environments.
Below the preferred embodiment of the invention is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the invention spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
