about eating

The probe 1 is connected to the casing unit A.

The conductor consists of an elastic sheath 5, elastic mountain-shaped cylinders 6 and 7, the side walls of which are thicker than the outer. The olive 8 of the conductor includes a chamber 9, in which four corrugated sections 10, 11, 12, 13 are placed, abutting against the front 14 and rear 15 walls of the chamber 9. In the center of the chamber 9, between the corrugated sections 10, 11, 12, 13 is placed spring 16, the ends of which also abut against the front 14 and rear 15 walls of the chamber 9, Ducts 17, 18, 19, 20, which are connected in pairs with cannulas 21 and 22, extend from each corrugated section 10,11,12,13 bodies of a conductor, consisting of two devices for the right P and left L of the doctor’s hand, including two cylinders 23 and 24 with pistons 25 and 26, connected by a rod 27, on which the trigger 28 is attached and a return spring 29 placed on the handle 30.

The olive 8 is located in front of the toroidal balloon 6, is located in the recess of the washer-shaped partition 21 and is connected to the duct 32, the other end of which is connected to the compressor III. A corrugated section 33 is adjacent to the washer-shaped partition 31, the opposite end of which abuts against the washer-shaped partition 34. Inside the corrugated section 33, air ducts 17, 18, 19, 20 and 32 are freely and excessively placed. An air duct 35 which is connected from the corrugated section 33 to compressor II. The exit points of the ducts 17, 18, 19, 20 and 32 in the wall of the corrugated section 33 are sealed. In the washer-shaped partition 34, a recess is selected in which a toroidal balloon 7 is placed, the side surfaces of which are thicker than the outer part. A duct 36 is connected to it, starting from compressor I.

Compressors K consist of an electric motor D, to the axis of which a crankshaft 37 is connected, the pitch of which is regulated by an H-shaped bar 38 connected to the rod 39. The rod 39 is connected to a piston 40 located in the cylinder 41. to which air ducts are connected, and each compressor I, II, III has a corresponding duct 36, 35, 32. The wheel of the chopper 42 with a tooth is attached to the axis of the electric motor D, 43, which alternately contacts either the upper limit switch VKV or the lower limit switch VKN .

The electrical circuit of the automatic current distributor includes starters for magnetic compressors (PM1, PM2, PMZ)., Upper limit switches (VKV1,

VKV2, VKVZ), lower limit switches (VKN1, VKN2, VKNZ), a control circuit switch (B1), a switch for moving the pistons of all compressors up (B2), turning on the pistons of all compressors down (ВЗ).

The device operates as follows. The end of the device is inserted through the natural opening of the digestive tract (through the mouth or rectum) or through an artificially created fistula to the maximum depth. When the passive advancement of the device is impossible, take the guides of the conductor in the right and left hands, while the index fingers are laid on

0 triggers 28, knowing at the same time that the right guide of the conductor raises and lowers

olive 8, $ left guide guide

shifts it horizontally

. right or left. Next, the compressor system K is connected. Before starting the compressors, the circuit breaker B2, BZ is turned off and the circuit breaker B1 is turned on. In this case, the pistons of all three compressors will occupy the lower position. After that alternately

0 the circuit breaker B3 and B2 are turned on. Subsequently, the electrical circuit operates automatically according to the program.

The compressor operation program is as follows. I, the compressor starts operation, makes half a turn of the wheel-chopper 2, this corresponds to the movement of the piston 40 from the lower to the upper position, which will lead to the inflation of the toroidal cylinder 7, into which the air from

0 of the compressor enters through duct 30. The outer wall of the toroidal balloon abuts against the wall of a hollow organ, such as the gut, and fixes the conductor at this point. Automatically I compressor

5 turns off, II turns on automatically and does a similar job - it distills the air through duct 35 into corrugated. section 33, which is thereby pulled forward and the compressor shuts down. A III compressor is turned on, which distills the air through duct 32 into a toroidal one. the balloon 6, inflates it, as a result of which the outer wall of the balloon abuts against the wall of the hollow organ, and fixes the conductor in the lumen of the organ, the compressor turns off and on; I the compressor performs half a revolution with the switch wheel 42, in connection with which the piston 40 moves from the upper position to the lower one and draws air from the toroidal balloon 7, the conductor in this section loses its fixation with the wall of the hollow organ, the compressor turns off and the II compressor turns on. performs a similar job and removes air and corrugated section 33, which will lead to its reduction and the movement of the probe 1 forward. After turning off the II compressor, the III k turns on, the compressor turns off the air from the toroidal cylinder 6. After turning off the III compressor, I turns on and the cycle of work is repeated again. During the operation of the conductor, the pulling probe 1 with the help of the conductor guides moves the olive 8 up or down, to the right or left - they seek out the lumen of the hollow organ. To do this, the trigger 28 on the right or left guide of the conductor is pressed or released with the index finger. Aspirator A connected to probe 1. aspirates the contents from the hollow organ. Through the cannula 44, antifriction fluid or drug solutions are introduced into the lumen of the probe, which exit through the openings 2 into the lumen of the hollow organ.

The conductor may remain in the lumen of the hollow organ or be removed if it extends beyond the hollow organ, for example through the rectum or fistula created on the organ. The disconnection of the conductor from the probe 1 is done manually. For this fitting, the conductor is disconnected from the ducts, and the probe 1 is pulled so that the end reaches a certain level.

Detachment of the conductor can also be carried out in the lumen of a hollow organ. For this purpose, a groove 45 is selected at the end of the probe T having uneven walls and into which a balloon 46 is inserted, the base of which is attached to the end of the washer-like partition 34 and connected to the duct 47, equipped with a pressure gauge 48 and a device for pumping air 49 equipped with valve 40. In the inflated state, the cylinder 46 is held in groove 45 and connects the conductor to the probe 1. After releasing air using valve 50, the conductor is disconnected from the probe 1. After turning on the compressors K, the conductor moving or exits through the EU ety hole or through an existing fistula.
