Description

DESCRIPTION

ENDOTRACHEAL TUBE FIXER

OBJECT OF THE INVENTION

The present invention relates to a harness-type endotracheal tube fixator with anti-decubitus hydrogel pads.

Critical patient management is a care process generally associated with the connection of an Invasive Mechanical Ventilation system through an endotracheal tube (ETT) or a tracheostomy, the main objective being to facilitate gas exchange at the alveolar level, as well as the decrease or replacement of respiratory work allowing the correct oxygenation of the body organs thus avoiding their degeneration and deterioration, a process that can be irreversible.

The fixation device object of the present invention is designed for the fixation of the endotracheal tube (ETT) after proceeding to the connection of a critical patient to Invasive Mechanical Ventilation after a successful intubation with the aim of performing a correct immobilization of this for minimize any risk derived from the mobilization of the patient when carrying out any task that involves handling the patient, such as accidental extubation.

The endotracheal tube fixator is divided into a main body, in which the fixation of this device to the endotracheal tube is produced, and a harness system, for the immobilization of both to the patient's skull.

The industrial application of this invention is within the sector of support devices and accessories and patient-machine interface, and more specifically, endotracheal tube fixators.

BACKGROUND OF THE INVENTION

Although no invention identical to the one described has been found, we present below the documents found that reflect the state of the art related to it.

Thus, document EP1061984A1 refers to a tracheal breathing device, especially a tracheal tube or tracheal cannula which, for the artificial respiration of a patient, closes the trachea as tightly as possible, comprising a balloon that blocks the trachea below the glottis and through which a breathing cannula of soft laminar material is introduced, where the balloon in a full state without limitation and freely deployed, is greater than that placed in a full state in the trachea, where the balloon it is adjustable with formation of folds to the trachea. It is, therefore, a tracheal breathing device as such, and not a system for fixing the endotracheal tube to the head, as proposed by the requested invention.

ES1134930U proposes a fixator for endotracheal tube comprising a tape configured to surround the neck of a patient that is provided with an essentially circular hole configured to receive said endotracheal tube, characterized in that the hole also comprises elastic teeth oriented towards the inside of said hole and which are configured to immobilize the endotracheal tube. Said utility model proposes a fixer for an endotracheal tube, whose fixation comprises a strap that surrounds the neck, and not, as described in the applied invention, by means of a harness that surrounds the head.

MX2015000696A describes an endotracheal tube support for pediatric patients characterized by comprising a support face bow and a slider that is mounted on the support face bow; the facebow support comprises a concave geometry and the slider comprises two sections: a clamp and an upper section that fits together with said support, said support supports an endotracheal tube. As in the previous document, it is a fixation different from the one proposed by the requested invention.

WO2014144656A1 claims a device for attaching an endotracheal tube to a patient and comprising: a track configured to fit next to a lip on the patient's face, which has a side in contact with the face, an exposed side opposite the side in contact with the face, and a pair of opposite ends; a tube support coupled and slidable along the track between the opposite ends; a releasably lockable positioning mechanism to allow selective lateral repositioning of the tube holder and an endotracheal tube thereby held along the track; a bite block carried by the tube holder and slidable with it along the track; and an accessory line channel positioned between the inner wall surface and an endotracheal tube extending through the central opening. Once again, it is a device for holding an endotracheal tube different from the one proposed by the requested invention, since it does not have the head restraint harness, object of said invention.

Conclusions: As can be deduced from the investigation carried out, none of the documents found solves the problems raised as the proposed invention does.

DESCRIPTION OF THE INVENTION

The endotracheal tube fixator object of the present invention is constituted from a cranial harness and the endotracheal tube fixator itself.

The harness surrounds the head from the back, passing to the face along two lines, one in the area of the cheekbones and the other behind the ear and mandibular arch until reaching four fixator insertion points.

The fixator, for its part, comprises the four holes for the aforementioned insertion points, as well as a gate for the entry of the endotracheal tube and elements to secure and fix the tube using buttons.

DESCRIPTION OF A PREFERRED EMBODIMENT

A preferred embodiment of the endotracheal tube fixator object of the present invention, with reference to the numerical references, can be based on a device to be placed on the patient's head/face, which consists of two pieces: a cranial harness (1) and a endotracheal tube fixator (2).

The harness (1) is made up of a network of bands (3), made of elastic and resistant hypoallergenic material, which surrounds the head from the back, passing to the face through two lines, one upper, through the area of the cheekbones, and another line, behind the ear and mandibular arch until reaching four holes (4) of the endotracheal tube fixator (2), located in its four corners, which comprises a butterfly wing shape.

These bands (3) must be arranged following a horizontal H in which the vertical band is holding the upper band from a point slightly above the posterior fontanel following a straight path until it meets the lower one in a place close to the foramen magnum, leaving the ends of the arms of said H as points of attachment to the body.

These bands must have an elasticity that allows adequate adaptation to the different cranial morphology that the patient may present, and in turn, present padding on the face that is in direct contact with the skin, since this minimizes the risk of ulcerations. derived from pressure, friction and even humidity generated in the area in patients whose nutritional intake, ventilatory and/or circulatory system are compromised.

As for the endotracheal tube fixator (2), made of hypoallergenic and antibacterial medical silicone, it comprises, in addition to the four attached to the corresponding four holes (3) mentioned, a central hole (5) with a lower opening (6) through from which the device will slide, surrounding the already implanted tube.

This lower opening (6) will be regulated by a closing mechanism (7) which includes a lower gate (8) whose initial position is the closing of the opening lower gate (6), and said lower gate (8) will be attached to a spring located inside the device which, through a pivot placed in the lower gate (8) will allow it to be manually slid inside the device, clearing the opening to slide the device leaving the ETT in a central position. Once there, the pressure exerted on the lower gate (8) will be released, which will close automatically.

On the other hand, in the upper medial part of the endotracheal tube fixator (2) there are immobilizing means (9) to fix the ETT to the device, which are provided with sliding buttons (10) through a flange system formed by a sliding part and a fixed part, where these will have the shape of a waning/crescent moon facing each other, inside which there will be a contact surface with the ETT that presents roughness that reaffirms the subjection.

In the endotracheal tube fixator (2) itself, it is essential to choose a material that has a degree of rigidity that allows it to withstand the traction force that the fixation tapes will exert on it, as well as the implementation of a system of opening to place it once the ETT has been implanted and the ETT's own fixation system.
