Specific implementation mode
The utility model is described in further details with reference to embodiment:
Embodiment one:
As shown in Figure 1, a kind of Medical pressurizer of the laparoscope cleaner of carbon dioxide driving, including carbon dioxide gas supply
Pipeline 1,1 rear end of carbon dioxide supply air line are connect with the import of conveyance conduit 2 and pneumoperitoneum apparatus 11 respectively by threeway.Delivery pipe
On road 2 normally closed solenoid valve 3, pressure reducing valve 4, surge chamber 5, pressure sensor 6, check valve are disposed with along gas motion direction
9 and pipeline valve 7, check valve 9 allows gas to pass through along from pressure sensor 6 to the direction of pipeline valve 7, avoids flushing liquor
Damage of the reflux to electronic equipment.The high pressure gas that supply air line 1 is supplied is depressured by pressure reducing valve 4, the gas after decompression
It is stored in surge chamber 5, while pressure sensor 6 is connect with controller 8, it is normally closed that controller 8 connect control with normally closed solenoid valve 3
