Sensor de oximetría.Oximetry sensor
El objeto de la presente invención tal y como se expresa en el enunciado de esta memoria descriptiva consiste en un "Sensor de oximetría", empleado para realizar una medida no invasiva de la saturación de oxígeno de la sangre.The object of the present invention as it is expressed in the statement of this specification consists of a "Oximetry sensor", used to perform a measurement not Invasive blood oxygen saturation.
Un sensor de oximetría se constituye comúnmente de un elemento emisor (comúnmente un LED) y un elemento receptor (comúnmente un fotodiodo) generalmente integrados en una carcasa, de la que surge un cable de conexión que transmite las señales hacia un oxímetro, o estación lectora.An oximetry sensor is commonly constituted of a sending element (commonly an LED) and a receiving element (commonly a photodiode) generally integrated into a housing, from which arises a connection cable that transmits the signals towards an oximeter, or reading station.
En base a esta descripción general es posible encontrar en el mercado un gran número de sensores de oximetría englobables en dos tipologías básicas, los denominados comúnmente sensores de oximetría reutilizables, y los sensores de oximetría desechables.Based on this general description it is possible find a large number of oximetry sensors on the market encompassed in two basic typologies, commonly called reusable oximetry sensors, and oximetry sensors disposable
Los sensores reutilizables son aquellos que se pueden emplear sucesivas veces en más de un paciente. Este tipo de sensores presentan el inconveniente de su elevado coste dado que al no poder separarse en sus elementos constituyentes, deben fabricarse con materiales capaces de soportar desinfecciones después de cada uso. Esta misma condición de solidez determina que cuando uno de los elementos constituyentes se estropea, deba enviarse el sensor en su totalidad para su reparación, disminuyendo sensiblemente el número de unidades disponibles en stock del hospital durante un número variable de días hasta que se devuelva reparado. Este hecho repercute directamente en la calidad de servicio que pueda proporcionar el hospital a sus pacientes, quienes por su parte expresan cierto rechazo hacia este tipo de sensores, pues debido a su carácter reutilizable, y al hecho de que establecen un contacto directo con su piel, muestran sus reservas con respecto a la higienización a la que se haya sometido el sensor.Reusable sensors are those that are they can use successive times in more than one patient. This type of sensors have the disadvantage of their high cost since not being able to separate into its constituent elements, they must manufactured with materials capable of withstanding disinfection after each use This same condition of strength determines that when one of the constituent elements breaks down, you must send the sensor in its entirety for repair, decreasing noticeably the number of units available in stock of the hospital for a variable number of days until it is returned repaired This fact has a direct impact on the quality of service that the hospital can provide to its patients, who in turn express a certain rejection towards this type of sensors, because of its reusable nature, and the fact that establish direct contact with your skin, show your reservations with respect to the sanitation to which the sensor.
Para eliminar este rechazo por parte de los pacientes surgieron los sensores de oximetría desechables, cuyo coste de fabricación menor al de los reutilizables permitía realizar un uso individualizado, de tal forma que cuando ya no se necesitara realizar más mediciones con el paciente que correspondiera, se desechaba aunque el sensor mantenía su funcionalidad. Por tanto, este tipo de sensor de oximetría surge más por la necesidad de que el paciente perciba que el servicio es de calidad, que por introducir mejoras técnicas al sensor.To eliminate this rejection by the patients emerged disposable oximetry sensors, whose manufacturing cost less than reusable allowed make an individualized use, so that when it is no longer you will need to perform more measurements with the patient than corresponded, discarded even though the sensor maintained its functionality Therefore, this type of oximetry sensor arises more because of the need for the patient to perceive that the service is of quality, that by introducing technical improvements to the sensor.
Este hecho evidencia el despilfarro en el que incurren los hospitales al tirar material útil y de importante valor económico aunque evita infecciones cruzadas entre pacientes por ser el material desechable.This fact evidences the waste in which hospitals incur when throwing useful and important material economic value although avoiding cross infections among patients for being the disposable material.
En este sentido, el nuevo sensor de oximetría presenta una configuración en la que parte del conjunto se desecha tras el uso, y parte se reutiliza maximizando el plazo de amortización y aumentando el grado de satisfacción que perciben los pacientes por el servicio recibido, ya que el sensor propiamente dicho no entra en contacto con la epidermis del paciente.In this sense, the new oximetry sensor presents a configuration in which part of the set is discarded after use, and part is reused maximizing the term of amortization and increasing the degree of satisfaction that the patients for the service received, since the sensor itself said does not come into contact with the patient's epidermis.
Concretamente, la parte reutilizable cuya función es la de captar la señal y transmitirla al oxímetro para obtener su lectura, consta de un sistema de captación de señal y otro de transmisión de dicha señal. El primero de ellos está constituido por un emisor encapsulado, un receptor encapsulado y un soporte. Mientras que el segundo está constituido por unos cables de conexión hacia el captador de señal, una caja de circuitería, y un conector capacitado para acoplarse al oxímetro.Specifically, the reusable part whose function is to capture the signal and transmit it to the oximeter to obtain its reading, consists of a signal pickup system and another of transmission of said signal. The first one is constituted by an encapsulated transmitter, an encapsulated receiver and a support. While the second is constituted by connection cables towards the signal collector, a circuit board, and a connector able to attach to the oximeter.
La parte desechable, cuya función principal es aislar al paciente de la parte reutilizable para evitar una posible contaminación por contacto, está constituida por un elemento aislante de material apropiado capaz de fijarse por una de sus caras a la parte reutilizable del sensor, y por otra entrar en contacto con la epidermis del paciente.The disposable part, whose main function is isolate the patient from the reusable part to avoid a possible contact contamination, is constituted by an element insulation of appropriate material capable of being fixed by one of its faces to the reusable part of the sensor, and then enter contact with the patient's epidermis.
Tanto el emisor como el receptor se hallan encapsulados independientemente en un cuerpo cuyas caras exteriores son opacas con excepción de una zona a modo de ventanilla a través de la cual el emisor emite luz, y el receptor la capta.Both the sender and the receiver are independently encapsulated in a body whose outer faces they are opaque with the exception of a window-like zone from which the emitter emits light, and the receiver picks it up.
Los elementos encapsulados se insertan en un soporte fijándose en éste mediante asientos removibles, de manera que puedan ser retirados si fuera necesario. Dicho soporte puede contener a los dos cuerpos encapsulados, o existir un soporte independiente para cada uno de ellos.The encapsulated elements are inserted into a support fixed on it by removable seats, so that can be removed if necessary. Such support can contain the two encapsulated bodies, or exist a support independent for each of them.
El soporte presenta una estructura que permite la comunicación luminosa entre el emisor y el receptor encapsulados de forma que sus zonas transparentes o ventanillas queden enfrentadas, para lo cual está realizado en un material flexible y elástico.The support has a structure that allows light communication between the encapsulated transmitter and receiver of so that your transparent areas or windows are facing each other, for which it is made of a flexible and elastic material.
Por otro lado, a dicho soporte se fija el elemento aislante constitutivo de la parte desechable del nuevo sensor de oximetría, mediante un sistema removible tal como puede ser un adhesivo, o cualquier otro sistema convencional que garantice la estanqueidad a la luz de dicha unión.On the other hand, to said support the insulating element constituting the disposable part of the new oximetry sensor, using a removable system as it can be an adhesive, or any other conventional system that guarantees the tightness in the light of said union.
El elemento aislante está realizado en un material flexible, y su configuración permite que la comunicación luminosa entre el emisor y el receptor encapsulados no se vea interrumpida.The insulating element is made in a flexible material, and its configuration allows communication light between the encapsulated transmitter and receiver is not visible interrupted
Una función secundaria del elemento aislante sería la de fijar el sensor de oximetría a la epidermis del paciente, para lo cual contaría con medios de fijación adecuados tales como una capa adhesiva.A secondary function of the insulating element would be to fix the oximetry sensor to the epidermis of the patient, for which he would have adequate fixing means such as an adhesive layer.
El emisor y el receptor encapsulados se hallan conectados, respectivamente, a un cable que por su otro extremo se conecta a un conector, que es el que se insertará en el oxímetro para el ingreso de datos. En un punto óptimo situado a lo largo de dicho cable se inserta una caja de circuitería, en la cual pueden incluirse circuitos electrónicos para blindar el sistema contra interferencias, circuitería analógica o digital para almacenar datos del paciente, optimizar datos, etc.The encapsulated sender and receiver are connected, respectively, to a cable that at its other end is connects to a connector, which is the one that will be inserted into the oximeter for data entry At an optimal point located along said cable is inserted a circuit box, in which they can electronic circuits included to shield the system against interference, analog or digital circuitry to store patient data, optimize data, etc.
Dicha caja se sitúa preferentemente lo más cerca del paciente al haberse comprobado que la proximidad hace más efectivo el filtraje de señal. Otras ubicaciones alternativas consistirían en integrarla en el sistema de captación de señal, en el conector, o finalmente incorporándola como elemento independiente mediante un cableado adicional.Said box is preferably located as close as possible. of the patient having found that proximity does more Effective signal filtering. Other alternative locations they would consist of integrating it into the signal collection system, in the connector, or finally incorporating it as an element independent by additional wiring.
Se ha comprobado empíricamente que la distancia más adecuada entre el emisor y receptor, cuando están colocados en el paciente, varía en función de la edad de éste. Así para neonatos la distancia recomendada es de 22 mm, en bebés de 19 mm, en niños pequeños de 19,5 mm, y en adultos de 23 mm.It has been empirically proven that the distance most suitable between the sender and receiver, when placed in The patient varies depending on the age of the patient. So for neonates the recommended distance is 22 mm, in 19 mm babies, in children small 19.5 mm, and in adults 23 mm.
