The specific embodiment
Embodiment one
The capacity buffer-type anesthetic machine of present embodiment/respirator waste scavenging system is equipped with vacuum suction cabin 3, pressure adjusting cabin 9 and attracts pneumatic filter 10 as shown in Figure 1 on the base 1.The top in vacuum suction cabin 3 is equipped with the top cover of periphery with the soft rubber sealing, top cover is provided with three interfaces, connect in one of them and can play the guiding and the waste gas stream guiding tube 4 of check valve dual function, outwards by connecing waste gas mozzle 6 on the T connector 5, connecing waste gas buffer air bag 2 down.Two interfaces connect the import that attracts pneumatic filter 10 by the attraction connection tube respectively in addition, and connect pressure adjusting 9 upper ends, cabin by regulating cabin connection tube 7.Vacuum suction cabin 3, pressure are regulated in the cabin 9 with the soft plastic film bag that is sealed with the top cover inner ring or are claimed to overlap capsule in the plastic sheeting, thereby cabin and outer cabin in by interior cover capsule the cabin body being divided into are separated waste gas and cabin body.The bottom in vacuum suction cabin 3 is regulated 9 bottoms, cabin, is attracted pneumatic filter 10 imports to be communicated with by internal negative pressure connection tube 13 and pressure, so after producing negative pressure, interior cover capsule will launch and be attached at two cabin inwalls.
The top cover that pressure is regulated cabin 9 is provided with the elbow bend that connects the vacuum suction cabin, and the interface of pneumatic filter 8 is overflowed in tipping.The port of export that overflows pneumatic filter 8 communicates with atmosphere, and therefore inner antibacterial filter membrane and the active carbon that is applicable to respirator and anesthetic machine that be equipped with respectively can be applied to different machines.
Attract the practice midwifery HC attraction system of living negative pressure of the outlet of pneumatic filter.Because respirator/anesthetic machine is discharged medical waste gas according to the intermittent discharging of respiratory rhythm, and the negative pressure that central suction produced is continuously.Therefore, when respirator/anesthetic machine not when discharging waste gas or discharge amount of exhaust gas lower (being in expiratory phase), the waste gas impact bag subsides and plays cushioning effect, attracts this moment to absorb in the cabin in the self-regulation cabin through the filtering room air of filter.And connecting pipe and adjusting volume of compartment amount are enough, and the inspiratory phase pressure of the respirator/anesthetic machine operate as normal that therefore can not exert an influence changes.When respirator/anesthetic machine discharging waste gas (being in expiration phase), abrupt release go out near or be less than the gas flow of tidal volume, directly be discharged in the waste gas impact bag by connecting pipe, under its cushioning effect, the exhaust resistance and the end expiratory positive pressure of the respirator/anesthetic machine operate as normal that also can not exert an influence.Respirator/anesthetic machine institute exhaust gas discharged was absorbed through attraction pipeline by the attraction cabin continuously in the toxic emission intermission.
Experimental results show that, the capacity buffer-type anesthetic machine of present embodiment/respirator waste scavenging system can constant negative pressure continue the waste gas that anesthesia machine system is discharged is attracted, automatically adjust internal pressure and captivation through self mechanical system, when removing medical waste gas, do not increase SR, do not influence machine intimate pressure, not limited by the influence of absorbability, no working time, and can be applicable to the treatment respirator.Overflow pollution to environment once more for what thoroughly prevent the part residual gas, the air ports place of this system is provided with defecator (being applied to anesthetic machine) that contains active carbon and the defecator (being applied to respirator) that contains the antibacterial filter membrane respectively.Waste gas is discharged outdoor via the central suction system, thereby has protected the depuration quality of operating room and intensive care unit(ICU) internal medium better, and the various waste gas of having avoided overflowing are to medical worker and other patient's health affected.
