The specific embodiment
Below in conjunction with accompanying drawing this utility model waste anesthesia gas treater is described in further detail.
Such as Fig. 1, shown in Figure 4, this utility model waste anesthesia gas treater comprises: this utility model waste anesthesia gas treater 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 is connected 4 by container waste gas of anesthesia import 3 and is connected with 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.The effusion meter module comprises effusion meter main body 12 and flow control valve 13.Module base 5 comprises: module waste gas of anesthesia import 14 and module waste gas of anesthesia outlet 15, module waste gas of anesthesia import 14 and the outlet of module waste gas of anesthesia 15 are 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 shell 1 by the rear port of this air chamber again, enter the waste gas of shell 1 through buffering, under the effect of negative pressure system, container waste gas of anesthesia by shell 1 exports 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-0.3cmH2O, and 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 this utility model waste anesthesia gas treater, 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.
The preferred embodiment of below this utility model having been created specifies, but this utility model is created and 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 this utility model creative spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
