BG30Y1 - Intubation guide (11) 31 - Google Patents

Abstract

The driver is designed to help intubation tube intrusion into the trachea patient in surgery, resuscitation and intensive care. It illuminates the larynx and simultaneously thereby intriguingly introduces the intubation tube under various anatomical features of the larynx and trachea. The guide includes a pipe (1) mounted on a handle (2) in which it is located a current source provided with a key (3) and connected by a conductor (4) arranged in the pipe (1), with a luminaire located at the distal end of the tube. The latter consists of two parts - rigid arcuate proximal and rigidly connected flexible spacer (6) part. At the front end of the distal portion (6) the end of a cable (8) is connected and the end is located the luminaire (7). The rear end of the cable (8) is connected to a slider (9) mounted in a guide a groove formed in the handle. Preferably, the tube diameter (1) is reduced by the point of attachment with the handle (2) to the distal end.

Description

Technical field

The utility model relates to the production of medical equipment and technical aids and will find application in anesthesiology, resuscitation and intensive care for the introduction of an intubation tube into the patient's trachea.

BACKGROUND OF THE INVENTION Intubation consists of introducing the trachea and / or bronchi of an intubation tube to ensure airway patency. The intubation tube is a rigid, curved arcuate plastic or silicone tube. Pipes of different sizes are produced, taking into account the anatomical features of the airways of different height and age groups of people.

Laryngoscopes are usually used to insert an intubation tube. A number of laryngoscope designs and other surgical assistive instruments are also known, specifically designed to assist atraumatic and reliable intubation.

An intubation laryngoscope (1) is known, which consists of a handle connected to a perpendicularly spaced blade which has a longitudinal opening through which a guide of steel wire, curved at right angles and attached to the blade is rotatable in its plane. at its lower end through the opening in the scapula. One end of the driver is connected to a ring and the other end to the working one has a semicircular shape. Through this semicircle, the end of the intubation tube is forced through and with a change in the position of the driver its direction is changed, it is adjusted against the larynx and the endtracheal tube is introduced. This tool does not provide visual and atraumatic due to the rigidity of the elements, requires precision in use and is complex to manufacture.

A device for navigating the body cavities (2) is known, consisting of an inner element and an outer element comprising concentrically and freely the inner element. The inner element is of a predetermined shape, which only appears when the inner element is outside the space bounded by the outer element, and when it is in that space, it is upright. The shape can be adjusted. It provides orientation of the entire set according to the branches and curves of the body cavities. The disadvantage of this construction is that it cannot be used on its own, since it does not provide visualization on its own and the closing arc cannot be changed during intubation.

A medical body cavity examination tool (3) is known which provides illumination of the object under study with the aid of a special device included therein. The tool consists of a hollow handle, a pipe connected to it and a working nozzle. The illuminating device consists of a command-source current source placed in the handle, a conductor placed in the tube, and a luminaire located at the end of the tube. This instrument cannot act simultaneously as an illuminating and penetrating tool and a guide to the intubation tube because of the tube's bent shape and the location of the lamp.

The technical nature of the utility model The problems associated with the need for visualization of the respiratory tract and the provision of atraumatic intubation are solved by a utility model - an intubation guide comprising a tube mounted to a handle in which a power source is provided with a key and connected by means of a conductor located in the tube to a luminaire located at the distal end of the tube. The tube consists of two parts - a solid arcuate proximal part and a flexible distal part fixed to it. At the anterior end of the distal portion, the luminaire is frontally mounted and the end of a strand extending along the tube is connected. The back end of the cable is connected to a slider mounted in a guide groove shaped into the handle.

Preferably, the diameter of the tube is reduced from the point of attachment of the handle to the distal end.

The advantages of the proposed intubation guide are the ability to modify the arch depending on the anatomical features of the patient at work without interrupting the intubation; the airways in the larynx are directly illuminated, the driver is easily detached from the intubation tube, is autonomous and can be used under the conditions of any operating and reanimation room and in an emergency in field conditions, the risk of injury to the trachea is minimized, it is easy to handle and its production is not complicated.

Description of the attached figure

Figure 1 is a longitudinal sectional view of the intubation guide.

Exemplary embodiment

The intubation guide shown in FIG. 1 consists of a tube 1 mounted to the handle 2, which houses a current source provided with a switch 3 and connected via a conductor 4 mounted in the tube 1 with a lighting fixture 5 located at the distal end of the tube. the pipe. The tube 1 consists of two parts - a solid arcuate proximal part and a flexible distal portion 6 attached to it. The luminaire 7 is fixed at the front end of the distal end and the end of the core 8, located along the tube 1, is connected. the end of the strand 8 is connected to a slider 9 mounted in a guide groove formed in the handle 2 not shown in the drawing. In a preferred embodiment, the diameter of the tube 1 is reduced from the point of attachment to the handle 2 to the distal end to facilitate removal of the driver from the endotracheal intubation tube after its placement in the trachea.

How to use the intubation guide. Before starting work on the intubation guide, the endotracheal tube is hoped. The driver and the intubation tube reach the vocal cords. The lighting is on. Depending on the anatomical location of the vocal cords, the curvature of the flexible distal portion 6 of the tube 1 is dosed with the help of the slider 9 so that its anterior end can be inserted into the trachea. The guide is then withdrawn and the intubation tube remains in the trachea. All actions are carried out without interruption of the process.
