Abstract

The invention relates to a cannula for tracheotomized patients. The inventive cannula comprises an inner tubular portion (5) and an outer truncated-cone-shaped portion (15) which is equipped with a peripheral flange. The inner tubular portion is provided with a projection (8) for fixing inside the trachea of the tracheotomized patient. The invention is suitable for the production of tracheotomy cannulas.

Description

Cannula for tracheotomy.

The present invention consists in a cannula for insertion into the

tracheotomy stoma individuals who have a fastening means

It can be worn with greater comfort than existing cannulas to date.

Cannulas for tracheotomy are devices that allow or

facilitate breathing through a stoma or perforation made directly from

the trachea to the outside, so that are introduced into the airway avoiding

accidental or annoying closures occur, and hindering the introduction of

particles, sweat, etc. generating great inconvenience to the tracheotomy.

Fixing cannulas has been carried out by means of

tethers cannula neck and / or chest of the wearer of the cannula.

This implies discomfort as any movement of the neck produces a

it unwanted friction and chafing, irritation and sores. In addition, in the cannulas

It occurs moisture condensation object of breathing, and existing mucosal

in the airway itself.

It is desirable, therefore, a cannula having a fastener

Outside or shield that prevents the cannula from moving inwards, and means

fij interioi ation, while the cannula is single piece, simplifying replacement. Thus in US 4315505, of Shilleylnc, a cannula is disclosed for

tracheo tomy with a disposable inner tube, in which an inner fixing occurs

given by an inflatable balloon interior, which is being swollen by

small pump that is actuated by oppression fingers outside. fixing

outside it is done by fixing a bonded tapes arranged grooves

on the sides of the shield of the cannula.

EP 0642803 discloses a cannula in which a plate is disposed or

shield provided with a plurality of perforations that facilitate breathability,

in addition to have grooves having as obj eto the outer fij ation of the cannula

means of fastening tapes.

EP 0691136 relates to a tracheotomy cannula in which

outer shield is fixed to an outer ring, which may be fixed tapes

fij corresponding inflation, so that the skin contact is performed only said

ring and not the entire plate. We see that here too fixated defined

efficient and to solve the problems described above.

EP 0920881 also discloses a cannula with an outer tube provided

an inflatable balloon as a means of internal fixation, by means of a device

external inflation, while the outer portion has one fij ation by a

small shield support. EP 0768096 also presents a cannula provided with an inner tube and an outer, but in which no means of attachment inside or outside defined.

US 5460176 also discloses a double cannula device, one

indoor and outdoor, which also means external and internal fixation are defined.

US 6053167 also presents a cannula shield and outer fastening articulated inner inflatable balloon on an outer cannula, an ar susceptible clo interior.

The invention that we propose, relates to a cannula which is provided with a means of external fixation and an average inner fastening means being external fixation annular flange, and the mean inner fastening projection protruding from the tube cannula, said inflation means fij susceptible to being used in simple cannulas or provided outside of cannulas

inner and outer ducts.

In order to illustrate the explanation which will follow, attached to the present specification three sheets of drawings, in which six figures represent the essence of the present invention is shown and wherein:

Figure 1 shows a view of the cannula from the outside, according to position of use,

Figure 2 shows a front view of the same cannula from the part

interior, also according to the position of use,

Figure 3 shows a side view of the cannula,

Figure 4 shows a section of the cannula according to the vertical plane A-

A 'of Figure 5,

5 shows a top view of the cannula, and

6 shows a schematic view of the trachea provided with the

cannula in use position.

Since the cannula is inserted into the patient's trachea with

tubular portion inwardly, and said inner curve side down,

We denominate inside of the tubular portion, the widening outside that

the cannula has at one end, and top and bottom views the

corresponding to the use position being upright patient.

In these figures we note 1 that the said cánuJapropiamerjle

It has two portions, a first outer 15, to be located outside the tracheotomy, and a second inner 5 consisting of a tubular portion arcuately, being located at the bottom end of the arch, in the use position, being the outside connected with the inside through a duct 3.

The outer portion preferably has frustoconical shape, by

be the shape that best fits the stoma 12, so that the closure is optimal, but may also have any other shape that is satisfactory for the object

alleged.

The outer portion has an inner surface 7 which will rest on the stoma, and an outer 6 will allow the addition of additional features such as a phonic device, filters or other elements.

The contour of the outer portion is preferably provided with a peripheral flange 2 supports on the skin and prevents li said outer portion 15 is key to the stoma, or in extreme cases to penetrate to the trachea 13.

It is foreseen the incorporation of grooves 4 for attaching fastening tapes, although this feature is complementary to the described invention, since the fixing is performed cannula itself.

The tubular portion which determines the portion of the cannula located inside the tracheotomy, arranged at a distance from the outer portion an emerging projection 8 sideways 10 and top 9, always in position

use. We see that this projection assumes emerging from a top view

crescent shaped, thus adapting to the tubular shape of the trachea. Fixing the

resulting in a stoma both inner and outer mounting, allowing without producing

discomfort neck movements, since this fixing device is produced

always a self-adaptation of fixation and self-positioning, with no possibility

accidental exit of the cannula from its position of use.

All edges are represented in this device are

rounded, with appropriate curvatures for a perfect ACCOMMODATIONS not

it produces discomfort or adversely affecting the user.

Not defined any limitation on the materials used, resulting

advisable for realization elastics, such as natural latex, or

combination of materials depending on the need.

This cannula may also be used as outer cannula

housing an inner conduit.

It is applicable to the manufacture of cannulas for tracheotomy.
