RU122572U1 - DEVICE FOR THE SELECTIVE TREATMENT OF EROSIVE AND ULCERAL BENEFITAL DISEASES OF THE ESOPHAGUS, STOMACH AND DUODENAL - Google Patents

Abstract

A device for the treatment of erosive and ulcerative lesions of the esophagus, stomach and duodenum, including a gastric tube with perforations on its distal and middle parts at an equidistant distance from each other, inside which a flexible tube with a plug is inserted, at the distal end of which holes are made, located circularly at the same level or in a spiral, while elastic cuffs are mounted on the tube on both sides of the holes with the possibility of sealing the space between the outer walls of the tube and the probe.

Description

The present utility model relates to medicine, namely to gastroenterology and surgery.

A known method of treating erosive and ulcerative lesions of the esophagus, stomach and duodenum by local exposure to the ulcerated mucosa by various drugs: liquid, oil, glue, gaseous, as well as low-energy laser radiation. In this case, the drug or laser light guide is supplied to the affected surface through a standard endoscopic needle or catheter, which is passed through the working channel of the fibroesophagogastroduodenoscope. The procedure is performed up to three to seven times a day until the mucosal defect is completely healed (N.E. Chernekhovskaya "Modern Technologies in Endoscopy", Moscow, Russian Medical Academy of Postgraduate Education, 2004-136 pp .; N.E. Chernekhovskaya, V. G. Andreev, D.P. Cherepyantsev, A.V. Povalyaev. - M: MEDpress-inform, 2009, - 135-138 p.).

The disadvantage of these methods is the need for repeated esophagogastroduodenoscopy, which is negatively perceived by patients, increases the risk of damage to the esophagus, negatively affects the condition of patients who are often in serious condition, and is also associated with significant material and technical costs.

The closest analogue of the utility model is a device consisting of a double-lumen nasojunal probe of the Dobhoff type from Covidien company, catalog number 8884752513 intended for decompression of the stomach and nasojunal nutrition (Covidien catalog on opraflex.ru/NDA_Catalogue_2011.pdf.dfdf 2011, pp. 139-140).

The disadvantages of the analog device are the impossibility of selective drug delivery directly to the zone of erosive-ulcerative lesions of the mucous membrane of the esophagus and stomach, as well as the impossibility of dosed exposure in the case of using gaseous drugs.

The objective of the utility model is to increase the effectiveness of treatment of patients with this pathology, especially those in critical condition.

The technical result of the utility model is to reduce negative features, reduce the morbidity and complexity of the procedure; reduction of procedure time; single introduction of the device; the possibility of introducing a device for treatment through the nasal passages; the possibility of prolonged and repeated use; selectivity of impact, reduction of material and technical costs.

Figure 1 shows a General view of the device, figure 2 - probe 1, figure 3 - flexible tube 3.

A device for the selective treatment of erosive and ulcerative benign diseases of the esophagus, stomach and duodenum (Figs. 1 and 2) contains a gastric tube 1 with perforations 2 at its distal and middle parts at an equidistant distance from each other. A flexible tube 3 with a plug has been inserted inside the probe 1. At the distal end of the tube 3 (Figs. 1 and 3), holes 4 are made, arranged in a spiral at a limited length or circularly at the same level. At the same time, elastic cuffs 5 are installed on the tube 3 (Figs. 1 and 3) on both sides of the holes 4 to ensure sealing of the space between the outer walls of the tube 3 and the inner walls of the probe 1. Marks can be made on the outer surface of the tube 3 to determine the depth of insertion at a known equidistant distance from each other.

The operation of the device is as follows.

The probe 1 is inserted into the stomach by the usual method, preferably through one of the nasal passages and fixed to the outer part of the nose and face skin with adhesive plaster. If necessary, the distal part of the probe is installed in the duodenum. A tube 3 is inserted into the probe 1 to a length sufficient to reach the area of erosive-ulcerative lesion. Moreover, the length of the introduced tube 3 is determined in advance when performing primary esophagogastroduodenoscopy. The introduction of drugs, as well as the laser fiber is carried out through the proximal end of the tube 3. Installed elastic cuffs 5 on the tube 3 on both sides of the holes 4 are sealing the space between the outer walls of the tube 3 and the inner walls of the probe 1, and thus provide selective drug delivery to the area to the area of erosion or ulceration of the mucosa. In the presence of several foci of lesions of the mucosa, the tube 3 is moved to the length necessary for selective exposure.

Moreover, when using gaseous medicinal substances, for example, exogenous nitric oxide, the excess of the gaseous substance can spontaneously be removed outside through probe 1, preventing overstretching of the stomach and providing a dose-dependent therapeutic effect

After the procedure, the tube 3 can be removed from the probe 1. The probe 1 can be in the stomach for a long time and used to introduce nutrient mixtures, and also play the role of a “control” gastric probe in case of bleeding.
