First normal pressure, the second normal pressure and the 3rd normal pressure can also enter according to the practical situation of specific works
Row setting, can be typically safe pressure threshold value by the 3rd normal pressure, the first normal pressure is the 80% of the second normal pressure,
Second normal pressure is the 80% of the 3rd normal pressure, so setting not only applicable routine operation, and is easy to use personnel
3rd normal pressure only need to be set to the safe pressure threshold value of reality, need not arrange the first normal pressure again by setting
With the second normal pressure.
When exceeding safe pressure threshold value in organ of performing the operation, drawn water, and then reduced intraorganic pressure of performing the operation, worked as handss
When in art organ, pressure rises, this patent pass through to predict next second or under the pressure condition of several seconds, according to the pressure condition of prediction,
The control carrying out into water and drawing water, and then reach the purpose of anticipation, prevent the operation intrinsic pressure power of organ too high, reduce in operation organ
Pressure reaches the probability of safe pressure threshold value;When the intrinsic pressure power of organ of performing the operation does not rise, according to the real-time pressure situation recording, enter
Traveling water and the control drawn water, prevent from closing water inlet because of anticipation and then affecting cleaning performance.This patent reduces because of surgical device
Hypertonia in official and the operation risk that causes and postoperative risk, improve the safety of operation.
According to actual use needs, in this patent, endoscope's water filling input pipe 8 also can be by endoscope's gas injection input pipe generation
Replace, endoscope's backwater outlet tube 9 also can be replaced by endoscope's return-air outlet tube.
The foregoing is only the specific embodiment of the present invention, but the technical characteristic of the present invention is not limited thereto, Ren Heben
The technical staff in field in the field of the invention, all cover among the scope of the claims of the present invention by the change made or modification.
