GR1010177B - Articulated tube introducer (bougie) for intubation - Google Patents

Abstract

Novelty: an articulated elastic intubation bougie (tube introducer) the final end of which is vertically bending through the lifting of the syringe plunger (fig.2) is disclosed. Constitution: said articulated elastic bougie (fig. 1) consists of: a syringe (1), the connection (2), an elastic bougie (3), an inelastic thread connecting the syringe plunger to the flexible lower end (4), and a flexible lower end (5). Advantages: 1) potential vertical bending of the end by lifting the syringe plunger, which is very important in cases of difficult intubation; 2) easy and cheap construction from low-cost materials; 3) easy utilisation since the only difference from a simple tube introducer (bougie) is that pulling the plunger of the syringe the curvature of the final end changes; 4) it is disposable. Embodiment: the invention can be used in all cases of difficult intubation.

Description

Articulated intubation wax

DESCRIPTION

This invention relates to a standard hinged candle for endotracheal intubation, is disposable and offers the possibility, by pulling the plunger of a syringe, to bend its terminal end vertically.

Before proceeding with the description of the invention, it would be useful to refer to some terms that will help in understanding it.

1. Intubation is the process of inserting a tube, the endotracheal tube, through the mouth into the trachea.

This procedure is done so that, by creating a passage through which oxygen passes through the respiratory mechanism, the patient's breathing can be helped.

2. Difficult airway is the clinical condition in which a conventionally trained anesthesiologist experiences difficulty in face mask ventilation or endotracheal intubation or both._The incidence of unanticipated difficult airway using a laryngoscope ranges from 0.5-13%

3. Difficult laryngoscopy is the inability to directly visualize, using a conventional laryngoscope, any part of the vocal cords after many attempts.

4. Difficult endotracheal intubation is the inability to properly place the endotracheal tube after at least three attempts at direct

laryngoscopy, where the latter (2+1) is performed by a more experienced anesthesiologist and/or with the use of auxiliary means.

5. Candle for endotracheal intubation The candle for endotracheal intubation (tracheal tube introducer or

gum — elastic bougie) is a flexible rod with a blunt end 60-70 cm long, ending in a curved end. The convexity of the tip allows the wax to be guided blindly forward under the base of the epiglottis and through poorly visible and/or invisible vocal folds. Then with the laryngoscope in place the ETS is guided over the candle which is then withdrawn. ·

Airway management is critical to safety during anesthesia because the most serious problems associated with anesthesia involve or involve the airway.

The main indications for tracheal intubation are:

• the support of ventilation and oxygenation

• the protection of the airway

• the definitive securing of the airway

• administering anesthesia and performing surgery

· the ability to care for the airway.

With the use of the already existing conventional disposable candles, there is no possibility of checking and changing the convexity angle of only the lower end during the laryngoscopy.

This results in the anesthetist not being able to use them when the angle formed by the pharynx with the laryngeal axis is greater than 30°

There are, of course, candles with a movable lower end for single or multiple use. These, however, do not use the syringe to lift the lower limb, while they have complex mechanisms making their construction much more expensive. And multi-use candles use materials resistant to sterilization, naturally increasing their cost, while there is always the risk of contamination.

The advantages of this invention are that:

• It is a hinged candle that offers the possibility of vertical bending of its final end by lifting the plunger of the syringe, which is located at its proximal end (DRAW No 2). Thus, we can change the angle of the tip of the candle, something very important in cases of difficult intubation.

• The mechanism is therefore simple, and very cheap to manufacture from low-cost materials.

• Easy to learn to use, since the only thing that differs from a simple candle is that by pulling the plunger of the syringe, the convexity of the end tip changes.

• It is disposable.

This hinged candle with movable lower end as shown in DRAWING No. 1 consists of :

1. A syringe

2. The connection

3. A rubber candle

4. An inelastic thread connecting the syringe plunger to the flexible lower end

5. A flexible lower end (rubber tube)

This hinged candle with a movable lower end is not inferior to the simple candle.

However, it has an additional flexible lower end that enables it to change the angle of its final end and to be able to direct more easily and quickly to the entrance of the trachea, without the need for traumatic manipulations and straightening of the pharynx with the laryngeal axis.

This invention is useful:

• in cases of difficult intubation where it is difficult to straighten the angle formed by the pharynx with the laryngeal axis

• in intubation with a video laryngoscope where we can see the glottis but cannot direct the endotracheal tube

• and for installing a double lumen pipe
