Description

Improvements introduced in the prolonged tracheal cannulation procedures.

The present invention aims at improvements introduced in the current systems medical-surgical and acting in medicine of urgency to proceed with tracheal cannulation of character prolonged in the neck area, in patients who are essential or necessary the prevention of granulomas in this type of performance, improvements that will be described with everything detail below.

State of the art

The procedures currently used in the tracheal cannulation polongada in the neck area, do not offer the full guarantee of protection of the interior walls of the area the trachea where the intervention is carried out, as it does not have the auxiliary or complementary elements necessary to avoid that the perforated silver cannula, of classical use, enters contact with the delicate tissues of that tracheal area.

Description of the invention

The cannulation procedure system Prolonged invention is based on the adoption of a set of three elements, to be used by the doctor who must carry out the intervention, which are described below:

A cannula of permanent implantation silicone through the tracheostoma, the which has, as a characteristic and differential element, a suprastomal extension that ensures duct permeability laryngotracheal with the rest of the trachea.

A setter and rectifier of the aforementioned cannula that allows to align it in the moment of its introduction through the tracheostoma until contact with the back of the trachea, allowing said positioner, when removed that the top of the cannula is introduced and positioned favorably in the supraostial zone of That place of the trachea.

A cannula Classic perforated, made of silver, or biocompatible material of polyvinyl chloride, which, introduced through the interior of the permanent cannula indicated in the previous paragraphs, properly placed without damaging or traumatizing the stoma, since in that introductory action is protected by the repeatedly mentioned permanent implant cannula.

Detailed description of the invention

The improvements of the invention are based in the use of a permanent implant cannula (1), made of silicone, provided in its part front-exterior of a plate (2) for clamping, and which presents an angular bend, at whose vertex, located in the area lower, has an opening (3), while the inner end it has a suprastomal extension located in position substantially vertical (4), ending in an opening (5) with a bevel cut This vertical extension (4) of the inner end, ensures the permeability of the laryngotracheal duct with the rest of the trachea.

The setter (6) consists of a shape bolt cylindrical and rounded inner end (6a) while its other end, also rounded, has an annular shoulder (7) of similarly rounded edges.

This setter (6) is inserted inside of the permanent cannula (1) to align it and obtain the position of optimal introduction of the cannula into the trachea (8), as draw in figure 4, the annular shoulder (7) being the one that limits the excessive insertion of the inserter (6) inside the cannula permanent (1). This cannula (1) is aligned in position longitudinal, including its vertical inner end (4), favoring in this way the introduction of the set cannula-placement inside the trachea (8). to through the opening or tracheostoma (9) until it makes contact with the back of the trachea.

When removing the setter (6) and follow it time, introducing the permanent cannula (1) inwards, as shown in fig. 5, the vertical inner end (4) of the same and due to the flexibility of the material it bends spontaneously up to enter the portion supraostial (10) of the trachea (8). The bevel cut (5) of that extreme part (4) of the permanent cannula (1) prevents injury from contact with the posterior face of said supraostal portion (10) of the trachea (8), area where the larynx and the cords meet vowels.

The perforated cannula (11), made of silver or of biocompatible polyvinyl chloride material and form and Classic features, presents a curved shape, with a front plate (12) for proper support and holes (13) at the elbow of its curvature.

Said perforated cannula (11) is introduced by the inside the permanent cannula (1), with the usual arrangement curvature inwards and downwards, in the direction of lungs, through the opening (3) that said permanent cannula (1) it has in its central lower part, being thus located so that the insufflated air from outside is directed towards the lungs to through the lower part of the trachea (8) while, through from the holes (13) the exhaled air passes to the larynx to through the vertical inner end (4) of the permanent cannula (one). This allows phonation by the patient by allowing and ensure the transmission of exhaled air to the larynx.

The manipulation of this perforated cannula (11) a through the inside of the permanent cannula (1) does not traumatize the tracheostoma (9), as it is protected by the mentioned cannula permanent (1).

Thus placed together the cannulas permanent (1) and perforated (11) can be fixed, so conventional, around the patient's neck.

Describe sufficiently the essentiality of refinements object of the present invention should be indicated that it will not be altered by design variations or types of material used in the practical realization of the three components described, summarizing this essentiality in the claims that follow.

Claims (3)

1. Improvements introduced in the procedures of prolonged tracheal cannulation, characterized by the fact that it consists in the use and implantation through the tracheostoma (9) of a permanent implant cannula (1), endowed with a suprastomal extension ( 4), substantially vertical and ending in a bevel cut opening (5), and an opening (3), located at the apex of its lower zone, also having a fitting (6), in the form of a cylindrical end bolt rounded (6) and an annular shoulder (7) limiting the introduction inside the permanent cannula (1), whose setter (6) is arranged inside the permanent cannula (1) aligning it and keeping it in that longitudinal position to facilitate the introduction of it into the trachea (8) through the tracheostoma (9), once the aforementioned permanent cannula (1) is removed. 2. Improvements introduced in the procedures of prolonged tracheal cannulation, according to the preceding claim, characterized in that the inner end (4) of the permanent cannula (1), of flexible material, is positioned spontaneously, bending upwards, to the Remove the inserter (6), entering the supraostial area (10) of the trachea (8), avoiding any injury thanks to a bevel cut of the extreme opening (5), thus permanently placing the implant cannula ( 1) for the introduction of a perforated cannula (11). 3. Improvements introduced in the procedures of prolonged tracheal cannulation where a permanent implant cannula (1) is previously arranged in the opening or tracheostoma (1), through which the perforated cannula (11) is placed, characterized in that said cannula perforated (11), preferably made of silver or biocompatible polyvinyl chloride material and in a conventional curved shape, is placed through the permanent cannula (1) with its curvature down in the direction of the lungs, through the opening (3) of the lower part of the permanent cannula (1), which allows, once said perforated cannula (11) is positioned, the passage of insufflated air into the lungs while through holes (13), which has at the bend of its curvature, the transmission of exhaled air to the larynx is possible, through the vertical inner end (4) of the permanent cannula (1), allowing phonation.
