SU1694147A1 - Device for performing esophageal intubation - Google Patents

Abstract

The invention relates to medicine, namely to devices for the prolonged intubation of the esophagus after its burn and perforation. The aim of the invention is to prevent airway compression. This is achieved due to the fact that the longitudinal section of the tube wall is flattened and, accordingly, there is a conical cut-out in the expanded part, opening with a base in the end portion of the tube, the cut-out base being equal to the tube diameter and flattening having a width of one third of the diameter. 1 hp ff, 3 ill.

Description

The invention relates to medical technology, namely to devices for long-term intubation of the esophagus after its burn, scarring and perforation.

The purpose of the invention is to prevent airway pressure.

Figure 1 shows a device for long-term esophageal intubation, a general view; figure 2 - section aa in figure 1; on fig.Z - section bb in fig, 1.

The device is made in the form of a tube 1 of a porous material (polyurethane foam), has a bell 2. The longitudinal section 3 of the wall of the tube 1 along the entire length is made flat and has a width of one third of the diameter. The bell 2 is made with a cone-shaped notch 4 with a base equal to the diameter of the tube and opening into the end portion.

The device is used as follows.

Patients after a sub-narcotic examination of the esophagus with an esophagoscope and an revealed pathology (esophageal perforation,

cicatricial stenosis, tracheoesophageal fistula, etc.) a tube is inserted into the esophagus. In this case, the notch and flattening 2 should be positioned strictly vertically on top (the position of the patient on the back). The position of the tube in the esophagus is monitored by esophagoscopic examination of the oropharynx and the upper esophagus.

The device should be located along the entire length of the esophagus, the proximal part (with the socket) of the tube is directly under the pharyngeal pulp, and the distal part is in the crust. With such a position of the tube, the possibility of compression of the respiratory tract is eliminated, it fits snugly to the mucosa along the entire length of the esophagus, and due to the socket is lowered. The tube is in the esophagus from 2 to 12 months, depending on the purpose. The tube is removed endoscopically by grasping the socket with a forceps and outward traction.

The device has the following advantages.

Ј VI

The use of the tube in patients with pathology of the esophagus does not lead to compression of the respiratory tract, which allows it to maximize its diameter. This, in turn, leads to the impossibility of saliva and food getting on the damaged wall of the esophagus. Tube design Allows treatment directly under the pharyngeal ring. When using a tube, there is no need to use frequent buddings or to apply therapeutic gastrostomy. The device is easy to operate, well tolerated by patients.

Claims (1)

1. A device for intubating the esophagus, containing a hollow tube with a socket, characterized in that, in order to prevent compression of the respiratory tract, the tube is flattened along its length, and the socket is made with a cone-shaped notch, the larger base of which is directed towards the open end of the socket, flattening and notch are in the same plane. 2, The device according to claim 1, wherein the flattening width is 1/3 of the diameter of the tube, and the larger base of the notch is equal to the diameter of the socket. l h /. / L ll Fe / g.2
