SU1814906A1 - Probe for intubating intestines - Google Patents

Description

The invention relates to medical equipment, namely to nasogastrointestinal probes intended for removal of toxic intestinal contents during surgical treatment of acute intestinal obstruction, peritonitis, as well as for feeding patients in the early postoperative period in the intensive care and surgical departments.

The aim of the invention is to reduce trauma to the intestine.

Figure 1 shows a probe for intubation of the intestine, General view: figure 2 - conductor for the probe; in Fig.3 - a probe with a conductor connected by a connector to a flexible tube, conducted through the 12 duodenum.

The probe for intubation of the intestine contains a flexible tube 1 with side openings 2 and a plug 3 and a conductor 4 with rigid spherical elements 5 with axial openings. The conductor is equipped with a tube 6 with a threaded fitting 7 with union coupling nuts 8, designed for detachable connection of the conductor 4 with a flexible tube 1, and a centering fitting 9 with a recess 10. chamfer 11 and gasket 12, and is also equipped with a thread 13 with its tension mechanism, located in the axial holes of the spherical elements 5 and rigidly connected to the spherical element located on the working end of the conductor 4 and having a larger diameter. The mechanism of tension of the thread 13 is made in the form of a swivel 14 rigidly connected to the thread 13 with a disk 15 mounted therein for rotation, a screw 16 installed in the threaded fitting 7, and a spring 17 rigidly connected to the disk 15 and the screw 16.

The probe is used as follows.

Before the operation, the flexible tube 1 is mounted on the proximal end of the two-way threaded fitting 7, the conductor

1814906 A1 and additionally strengthened with a union sleeve-nut 8. During the operation, the anesthesiologist conducts a probe through the right or left nasal passage into the nasopharynx, esophagus, stomach. The surgeon pushes the probe through the walls of the stomach into the duodenum and through the duodenojejunal inflection into the small intestine. When conducting the probe in the lower horizontal part of the duodenum, it is pushed with fingers through the intestinal wall behind the sleeve 8 of the conductor 4. The end sphere of the flexible flexible conductor 4 easily deviates towards the intestinal lumen, even from a slight obstacle, and after overcoming the sphere, the initial straight position is returned to / 15. The state of springy flexibility facilitates overcoming the obstacle even with pronounced bends in the area of the duodenojejunal transition, and the large terminal sphere of the conductor 4 is reliably held by the fingers of the surgeon, which accelerates the conduct of the probe from the 12 duodenum into the small intestine. Further carrying out the probe by sweat to the loops of the small intestine does not cause any special difficulties, due to the successive interception of the conduit 8 and the coupling nuts 8, which are contoured under the fingers, During the period of intestinal paresis, decompression of the liquid and gaseous toxic is carried out through the holes in the side wall of the flexible 30 • tube 1 contents of the small intestine. To adsorb and restore intestinal microflora, drugs are introduced into the probe, such as enterodesis, bactisubtil, etc. 3-5 days after the appearance of active intestinal motility and gas discharge, the probe is removed. Then the conductor 4 is disconnected from the flexible tube, washed in running water with a brush and soap, and sterilized in the first-moor solution for 30 minutes at room temperature.

A probe for intubation of the intestine makes it possible:

-t reduce injury to the intestines and surrounding tissues;

- expand indications for its intubation, both with the aim of aspiration of toxic intestinal contents, and nutrition of patients in the early postoperative period;

-accelerate and simplify the process of intestinal intubation;

. - make the probe economical and universal in the manufacture and use of a set of conductors.

Claims (1)

Claim A probe for intubation of the intestine, containing a flexible tube with side openings and a conductor with spherical. 'elements, characterized by that. that, in order to reduce trauma to the intestine, the conductor is equipped with a tube with a detachable connection fitting with a flexible tube and a thread with a mechanism for its tension, spherical. The elements are made rigid with axial holes to accommodate the thread, and the spherical element located on the working end, 35 has a larger diameter and is rigidly connected to the thread. Figure 2
