An air valve 10 is connected between the compressor 6 and the water tank 7. The pneumatic switch 4 is, for example, in the form of a tube with a hole in communication with the atmosphere. The water and air supply mechanism has a pressure relief device. The air from the water tank 7 is made in the form of an additional air line 15 connected to the water tank 7 and the pneumatic switch 4. The water line 8 is connected to the water tank 7, and the line for air 9 - with a distribution air valve 10. As starters 3 and 5, for example, microswitches type MP10 USO.360.074 TU can be used. As a distribution air valve 10, for example, an electro-pneumatic converter of the type ШПР.5 ТУ 25-02-380497-8IE can be used. The actuator 3 of the water and air supply mechanism is electrically connected 16 to the air distribution valve 10, and the aspirator actuator 5 is electrically connected 17 to the aspiration valve 11.

The pneumatic switch 4 can be made in the form of a tube with a shank (Fig. 4A). A diagram of the suction valve 11 is shown in FIG. Sound It is made on the principle of clamping rubber tubes. In the initial position, the tube communicating with the suction line 4 is clamped by a pusher using springs.

The design of the endoscope may have a slightly different implementation, as provided for in paragraph 2 of the formula, i.e. the endoscope (Fig. 2) contains a housing 1, a water and air supply control system 2, including a starter 3, a pneumatic switch 4, a suction mechanism starter 5. A water, air supply mechanism, including a compressor 6, a water tank 7, water supply lines 8 and air 9, an air distribution valve 10, an aspiration mechanism including an aspiration valve 11, a reservoir for collecting biological fluid 12, a vacuum pump 13, an aspiration line 14. An air distribution valve 10 is connected between the compressor 6 and the dc water tank 7. Pneumatic The static switch 4 (FIG. 3A) is made, for example, in the form of a tee, one opening of which communicates with the atmosphere, an air line is connected to the other through a non-return valve, and an air line is connected to the third, which is connected to the air distribution valve 10. Water line 8 is connected with a capacity for water 7, and the highway

for air 9, with a pneumatic converter 4. The latter is connected by an air line 15 to the air distribution valve 10. The actuator 3 of the water and air supply mechanism is connected by electrical connection 16 to the air distribution valve 10, and the starter 5 of the aspiration mechanism is connected to by electrical communication 17 with an aspiration valve 11.

The water and air supply mechanism in this embodiment has an air pressure relief device from a water tank 7 made in the form of an additional air valve 18 connected by an additional air line 19 to the air line 20 coming from the air distribution valve 10 to the water tank 7, and atmosphere. Additional air valve 18 is connected by electrical connection 21 to starter 3.

As starters 3 and 5, for example, microswitches of the MPYU USO.360.074 TU type can be used. As 5

10 and an additional air valve 18 can be used, for example, an electro-pneumatic converter of the type P1PR.5 TU 25-02-380497-81E.

The endoscope (Fig. 1) works as follows.

When the compressor 6 is turned on, air enters through the air distribution valve 10 into the water tank 7 and through the air line 15 leaves the pneumatic converter 4 to the atmosphere, therefore, water from the water tank 7 will not be forced out and will not enter the water line 8; when the finger blocks the outlet of the pneumatic converter 4, the air entering the water tank 7 from the air distribution valve 10 will not exit the water tank 7 and will put pressure on the water, which will go under pressure through the water line 8. When removing the finger from the outlet of the pneumatic converter 4, the air pressure in the water tank 7 will immediately decrease to atmospheric and the water will immediately stop flowing along the water line 8, since at that moment the water tank 7 will communicate with the atmosphere through the additional air line 15 and the holes of the pneumatic converter 4. When the actuator 3 is pressed, the air distribution valve 10 will be turned on, while the air from the compressor 6 will be supplied through the air distribution valve 10 through

 In the case of a constructive solution in accordance with paragraph 2 of the formula, the endoscope (Fig. 2) works as follows: when the compressor 6 is turned on, air enters the control valve 10 and then along Line 15 to the pneumatic switch 4 from which it exits into the atmosphere through an outlet (not shown), when this hole is closed with a finger, the air enters the air supply line 9, when the starter 3 is pressed with a finger, the air distribution valve 10 and an additional air valve 18, when this pressure air from the compressor 6 enters the tank of water 7 and removes water from it, which is supplied through the {water line 8.
