Description

 The invention relates to medicine, namely to surgery.

 The closest analogue of this device can be considered a Muller-Abbot probe, which consists of two paired tubes: polyvinyl chloride with a diameter of 2.5 mm and a rubber diameter of 0.5 mm. At the end of the polyvinyl chloride tube, an olive is fastened from a conventional duodenal probe, over which a can of thin rubber 5.0 cm long is tied. The rubber tube ends before reaching a can of 1.5 cm (Linevsky Yu.V., Pavlova I.S. Artificial hypotension in the X-ray diagnosis of intestinal diseases, Kiev, 11976, S. 26-28).

 The main disadvantage of this probe is the inability to evenly distribute liquid dosage forms along the length of the intestine.

 The aim of the invention is to develop a probe that provides a uniform distribution of the injected drug solution along the length of the intestine.

 This goal is achieved by the fact that the device is made in the form of two polyvinyl chloride tubes: a guide with a diameter of 0.9 cm, having on the inner surface every 30 cm an electrically conductive sealing ring connected to a monopolar electrode, both ends of the tube are closed with foam rubber circular couplings, and the distal the end has an evacuation tube for connecting to a vacuum suction and a working tube with a diameter of 0.5 cm and marks every 10 cm, located inside the guide, having two restriction valves ezinovye lining the outer wall of the working tube, between which the conductive restriction valve (rubber sleeve with a lamp connected to the electrode). Between two different valves are located in one gap - a hole for supplying a medical solution, and secondly - evacuation holes. A locking device is provided for connecting the ends of the working tube.

 A structural diagram of the device shown in the drawing.

 The device consists of a guide PVC tube 1, which along the entire length has perforation holes 2 and an inner channel with a diameter of 0.9 cm. On the inner surface of the tube 1 there are sealing rings 3 every 30 cm. Each sealing ring 3 is made electrically conductive. The sealing rings 3 are connected by monopolar electrodes 4. The distal end of the guide tube 1 is equipped with an evacuation tube 5, which is designed to be connected to a vacuum suction. In the proximal and distal sections of the guide tube 1, foam rubber circular couplings are placed 6. In the channel of the guide tube 1 is a working tube 7 with a diameter of 0.5 cm. The working tube 7 has two restriction valves 8, which are rubber pads on the outer wall of the working tube 7. Between them is an electrically conductive restriction valve 9, which is a rubber cuff connected to the electrode 10 containing a test lamp. The distance between the restriction valves 8 and 9 is 30 cm. In the first gap between the valves 8 and 9 of the working tube 7 there is an opening for supplying the medical solution 11. In the second gap between the valves 9 and 8 of the working tube 7 there are evacuation openings 12. The working tube 7 can advance along the channel of the guide tube 1 circularly. For this, it is provided that the proximal and distal sections of the working tube 7 are connected using the locking device 13. On the surface of the working tube 7, marks 14 are applied every 10 cm.

 Work with the device as follows. Intubation of the intestine with the indicated probe can be performed in the presence of enterostomy. In this case, one of the ends of the probe is discharged through the enterostomy, and the other is expediently carried out through a previously imposed gastrostomy. However, both the nasogastric and transanal routes of excretion of one of the ends of the probe can be used. Initially, the guide tube 1 is carried out. After that, the working tube 7 is introduced into the guide tube 1. It should be noted that if the introduction of the guide tube 1 is carried out directly during surgery, the introduction of the working tube 7 can be carried out at any time after the operation. With the aim of introducing the drug solution into the intestine and distributing it evenly, the proximal and distal ends of the working tube 7 are connected using the locking device 13. In accordance with the distance marks 14, the first intestinal fragment 30 cm long is delimited by means of restriction valves 8 and 9. the working tube 7 through the evacuation holes 12, the lumen of the guide tube 1 is further cleared of intestinal contents. Through hole 11, a drug solution is introduced into the intestinal lumen. After that, the working tube 7 is moved to the next fragment of the intestine. To introduce the solution, the ends of the probe are disconnected and the solution is introduced into its proximal end. Using the control lamp of valve 9, you can visually determine the location of the intestinal fragment into which the solution is injected, as well as more accurately control the correct installation of the valves, since the control lamp illuminates as a result of the contact of the valve 9 electrode with the electrode connected to the restriction ring 3. When the probe moves, the outflow the intestinal contents from the ends of the guide tube 1 are blocked by the couplings 6. In addition, according to the indications, intestinal intra-intestinal electrical stimulation can be performed, for which purpose nnye ends of the electrodes 10 and 4 are connected to a pulse current source.

 The use of this probe allows circular intubation of both the small and large intestines, the evacuation of intestinal contents, the fragmentary administration of drug solutions with a uniform distribution along the length of the intestine, and the performance of intraintestinal electrical stimulation.
