RU194891U1 - Endotracheal tube introducer - Google Patents

Abstract

The utility model relates to medicine, to the specialty anesthesiology-resuscitation, and is used to carry out planned and emergency tracheal intubation in difficult direct laryngoscopy. The purpose of creating a utility model is to facilitate tracheal intubation in unforeseen, planned and emergency difficult conditions, thereby ensuring patient safety. This goal is achieved by the fact that the introducer for the endotracheal tube having a distal and proximal ends and including a polyvinyl chloride tube with a diameter of 4.5 mm and a length of 700 mm, characterized in that at the distal end there is a video camera and an LED installed to enable the introduction of the introducer with a worn an endotracheal tube to the glottis under the control of the camera, and a channel for oxygen supply / aspiration of the contents, while at the proximal end there is a connector for connecting oxygen a hose and / or aspirator via a hose and a mini USB plug for connecting the camcorder to a mobile device. 3 ill.

Description

The utility model relates to medicine, to the specialty anesthesiology-resuscitation, and is used for tracheal intubation in difficult direct laryngoscopy. Direct laryngoscopy with subsequent tracheal intubation is the main manipulation in the arsenal of the anesthesiologist-resuscitator. Carrying out this manipulation depends both on the experience of the anesthetist-resuscitator, the presence of a certain type of laryngoscope, the patient’s placement, and on the availability of additional devices that facilitate the implementation of this manipulation. In most cases, a specialist can predict difficult intubation of the trachea (difficult intubation means a clinical situation in which an anesthetist-resuscitator experienced certain difficulties during 2-3 attempts of intubation and pulmonary ventilation, which took a total of 5 to 10 minutes) and prepare pre-necessary devices: different types of laryngoscopes, endotracheal tubes of different diameters, introducers for endotracheal tubes, endoscopic equipment. But there are cases of unforeseen difficult intubation of the trachea in planned and emergency anesthesiology and resuscitation.

Known introducer for endotracheal tube with a curved end. This device is taken as a prototype.

The purpose of creating a utility model is to facilitate tracheal intubation in unforeseen difficult conditions, thereby ensuring patient safety.

This goal is achieved by the fact that the introducer for the endotracheal tube is brought to the glottis, and then into the trachea under the control of the camera, and not blindly.

Comparison of the proposed device with others known in the field of medicine, shows its compliance with the criteria of a utility model.

The utility model is illustrated by graphic material.

In Fig. 1 shows the distal end of the device

It consists of a video camera (1), an LED (2) and a channel for oxygen supply / aspiration of contents (3).

In Fig. 2 shows the proximal end of the device

Consists of a connector (4), a mini-USB plug (5)

In Fig. 3 shows a general diagram of the device

Consists of a distal end (6) and a proximal end (7)

The introducer for the endotracheal tube is used as follows. If there is no visualization of the entrance to the larynx (and only the epiglottis is visible) during direct laryngoscopy, the introducer sheath for the endotracheal tube with the endotracheal tube put on in advance is inserted into the trachea under the control of the camera, thereby minimizing the risk of hypoxia during tracheal intubation. Right before use, the device connects to a mobile device that has a color screen via the mini-USB port. During the entire manipulation, it is possible to supply oxygen by connecting an oxygen hose to the connector, and / or to aspirate the contents, if necessary, connecting the aspirator to the connector via the hose.

Using the proposed device will allow:

1. To accelerate and secure the conduct of tracheal intubation with unforeseen difficult intubation,

Claims (1)

An introducer for an endotracheal tube having a distal and proximal ends and including a polyvinyl chloride tube with a diameter of 4.5 mm and a length of 700 mm, characterized in that a video camera and an LED are installed at the distal end, which are installed so that the introducer can be brought in with the endotracheal tube put on to the glottis under monitoring the camera, and a channel for supplying oxygen / aspirating the contents, while at the proximal end there is a connector for connecting an oxygen hose and / or aspirator dstvom hose and a mini-USB plug to connect the camcorder to a mobile device.
