RU2290213C1 - Naso-esophago-gastroscopic probe - Google Patents

Abstract

FIELD: medical facilities; surgical tools.

SUBSTANCE: probe is used for draining space of esophagus and for providing enteral feeding of patient having perforations of lower third of esophagus thorax. Naso-esophago-gastroscopic probe has silicone tube with side openings. Two tubes are glued to side surfaces of probe. Tubes are disposed in such a way that their distal ends are disposed at 20-25 cm aside from distal end of first tube. There are openings at distal ends of mentioned tubes at their free side surface. Adequate drainage and sanation of space of lower third of esophagus thorax can be complete when esophagus is damaged. Patient can be also fed through the probe.

EFFECT: improved efficiency of treatment.

Description

The invention relates to medical equipment, in particular to surgical instruments, and is intended for drainage of the lumen of the esophagus and simultaneous enteral nutrition of the patient with perforations of the lower third of the thoracic esophagus.

The closest technical solution adopted for the prototype is a silicone nasogastric tube (see Lesions of the esophagus; Komarov B.D., Kanshin N.N., Abakumov M.M .: Medicine, 1981, p. 91).

The disadvantages of the prototype are: the inability to provide adequate drainage and simultaneous sanitation of the lumen of the lower third of the thoracic esophagus with purulent mediastinitis.

The objective of the invention is adequate drainage and sanitation of the lumen of the lower third of the thoracic esophagus when it is damaged, as well as providing the enteral nutrition of the patient.

The task is achieved in that the naso-esophago-gastric probe, consisting of a silicone tube with side openings, is additionally equipped with two tubes glued to the side surfaces of the probe, located so that their distal ends are 20-25 cm from the distal end of the first tube.

The proposed probe is presented in the drawings:

figure 1 - General view of the probe;

figure 2 is a transverse section of the probe, where

A is the nasogastric part

B - aspiration part

C is the inspiration part.

The proposed naso-esophago-gastric probe consists of three silicone tubes glued together. The first tube (A) is the nasogastric part of the probe and provides the patient with enteral nutrition. The aspiration part (tube B) is designed for active suction of the contents of the esophagus. The tube (C) is the inspiratory part that provides for the irrigation of antiseptic fluid into the lumen of the esophagus.

This probe must be used only after applying a purse string suture to the mucous membrane of the esophagus using absorbable suture material that is tied around the probe, which prevents gastroesophageal reflux and provides prevention of suture failure during perforation of the lower third of the esophagus.

Example.

The developed probe: the diameter of the first tube (A) is 10 Fr on the Charrier scale, the second tube (B) with a diameter of 4 Fr, the third (C) with a diameter of 1 Fr. The tubes are connected so that the distal ends of the second and third tubes are 22 cm from the distal end of the first tube. At the distal end (A) there are 10 holes around the entire circumference of the tube, this section should be in the stomach. At the distal ends of the tubes (B) and (C) there are 8-10 holes on the free side surface, the other side surface (B) and (C) is connected to the tube (A). The distal ends (B) and (C) should be located in the lower third of the thoracic esophagus, the tube (B) for active suction of the contents of the esophagus, and the tube (C) is designed to inspire the antiseptic solution into the lumen of the esophagus.

Total length = 80 cm.

The length of the distal end of the nasogastric part (stump) = 22 cm.

The length of the suction part = 70 cm.

Inspection length = 70 cm.

The diameter of the nasogastric tube (A) is 10 Fr on the Charrier scale.

The diameter of the suction tube (B) is 4 Fr on the Charrier scale.

Diameter of the inspiratory tube (C) 1 Fr no. Charrier scale.

Thus, the present invention allows for adequate drainage and sanitation of the lumen of the lower third of the thoracic esophagus when it is damaged, and also provides enteral nutrition of the patient.

Claims (1)

A naso-esophagogastric probe, consisting of a silicone tube with side openings, characterized in that it is additionally equipped with two tubes glued to the side surfaces of the probe and arranged so that their distal ends are 20-25 cm from the distal end of the first tube, the distal ends of these tubes have openings on the free lateral surface.
