Abstract
The invention relates to a reflex hammer, which is a very useful medical instrument for evaluating neurological structures. For patellar and Achilles reflexes, a physician observes the reflex response range when the tendon is struck. Even though the reflex response range is a function of the force with which the stimulus is applied, there is currently no simple, rapid feedback that allows a health professional to evaluate whether the stimulus was applied correctly or not. There are also other relevant characteristics of the reflex such as latency, making it important to know when the stimulus was applied. The present invention enables a practitioner to receive immediate, reliable feedback on how the stimulus was applied, while providing additional information for further applications. The novel reflex hammer incorporates sensors and electronics that implement information extraction algorithms without said inlaid components significantly changing the weight or shape of the hammer in any way. The novel hammer immediately informs a practitioner whether the hammer experienced free fall before percussion, and provides information about the force of the impact and the moment of impact. The information can be displayed for the practitioner, recorded in the memory or transferred to a computer for record-keeping. A wireless or wired transmitter inlaid in the hammer sends the data to an independent external receiver.

La invención pertenece al campo de la instrumentación electrónica aplicada a la medición de parámetros fisiológicos del ser humano y al diagnóstico médico. The invention belongs to the field of electronic instrumentation applied to the measurement of physiological parameters of the human being and to the medical diagnosis.
Técnica anterior Prior art
El martillo de reflejos es un instrumento de gran uso en la práctica médica para evaluar las estructuras neurológicas. The reflex hammer is an instrument widely used in medical practice to evaluate neurological structures.
Es descrito como un "martillo con la cabeza de percusión de goma, de distintas formas, utilizado en la exploración neurológica para obtener los reflejos osteotendinosos o clinicomusculares mediante la percusión sobre el tendón." (Clínica de la Universidad de Navarra, España). It is described as a "hammer with a rubber percussion head, in different ways, used in neurological examination to obtain osteotendinous or clinomuscular reflexes by percussion on the tendon." (Clinic of the University of Navarra, Spain).
Hoy en día se utilizan principalmente dos tipos de martillos de reflejos. El martillo simple o de Taylor, que tiene una cabeza triangular de caucho y un mango de acero. Este martillo fue inventado por John Madison Taylor, médico norteamericano que vivió entre 1855 y 1931. Su diseño no ha tenido mayores modificaciones hasta la actualidad. Today, two types of reflex hammers are mainly used. The simple or Taylor hammer, which has a triangular rubber head and a steel handle. This hammer was invented by John Madison Taylor, an American doctor who lived between 1855 and 1931. Its design has not had major modifications until today.
El segundo tipo es el conocido como "martillo neurológico" que incorpora otras funciones tales como una aguja o un pincel que sirven para evaluar la sensibilidad. The second type is known as the "neurological hammer" that incorporates other functions such as a needle or a brush that are used to assess sensitivity.
La búsqueda de antecedentes previos indica la existencia de varias patentes de diseño en Estados Unidos, que reivindican distintas maneras de construir el martillo. Estos diseños no incorporan elementos sensores ni transmisores en los nuevos martillos. A modo de ejemplo se pueden citar los diseños "Reflex Hammer" US D535,025 S jan 9, 2007 y "Reflex Hammer" US D517,211 S mar 14, 2006. Existen pocos antecedentes de martillos de reflejos que hayan incorporado instrumentación. Una patente otorgada en Estados Unidos "Method and Apparatus for determining the density and structural integrity of biological tissues, medical implants and structural parts", Patent Number 5,836,891 , nov 17, 1998, se refiere a un martillo de reflejos que incorpora sensores con el objetivo de calcular la relación entre la fuerza del impacto y la fuerza del rebote para determinar la
densidad de tejidos. Tanto la utilidad que ofrece como las variables de interés que se obtienen con ese martillo son completamente diferentes a la presente invención. The search of previous antecedents indicates the existence of several design patents in the United States, which claim different ways of building the hammer. These designs do not incorporate sensor or transmitter elements in the new hammers. As an example, the "Reflex Hammer" designs US D535,025 S jan 9, 2007 and "Reflex Hammer" US D517,211 S Mar 14, 2006 can be cited. There is little history of reflex hammers that have incorporated instrumentation. A patent granted in the United States "Method and Apparatus for determining the density and structural integrity of biological tissues, medical implants and structural parts", Patent Number 5,836,891, Nov 17, 1998, refers to a reflex hammer that incorporates sensors with the objective of calculating the relationship between impact force and rebound force to determine the tissue density Both the utility offered and the variables of interest that are obtained with that hammer are completely different from the present invention.
Otra patente otorgada en Estados Unidos, "Electric reflex hammer" Patent Number 5,657,763 del 19 de agosto de 1997 contiene un interruptor al interior de la cabeza del martillo para generar una señal en el momento en que el martillo impacta en la rodilla del paciente. Este martillo solamente incorpora elementos pasivos, la señal que entrega se transmite por un cable y no tiene los componentes ni la funcionalidad para calcular parámetros dinámicos. Another patent granted in the United States, "Electric reflex hammer" Patent Number 5,657,763 of August 19, 1997, contains a switch inside the head of the hammer to generate a signal at the moment when the hammer hits the patient's knee. This hammer only incorporates passive elements, the signal it delivers is transmitted by a cable and does not have the components or functionality to calculate dynamic parameters.
En el plano industrial, existen martillos, distintos a los usados en medicina, que incorporan sensores para medir la fuerza del golpe. Por ejemplo, el denominado "Impulse Hammer" de la empresa PCB Piezotronics. Consisten en martillos conectados por cables a un dispositivo de registro y visualización. Registran los datos para que sean analizados posteriormente. On the industrial level, there are hammers, other than those used in medicine, that incorporate sensors to measure the force of the blow. For example, the so-called "Impulse Hammer" of the company Piezotronics PCB. They consist of hammers connected by cables to a recording and display device. They record the data to be analyzed later.

Problema técnico que resuelve. El martillo de reflejos es un instrumento de gran uso en la práctica médica para evaluar la indemnidad de las estructuras neurológicas. Technical problem that solves. The reflex hammer is an instrument of great use in medical practice to assess the indemnity of neurological structures.
En el caso del reflejo patelar y del reflejo aquiliano el médico observa la amplitud de la respuesta refleja que resulta de golpear el tendón con el martillo de reflejos. Sin embargo, la amplitud de la respuesta refleja es función de la fuerza con que se aplica el estímulo. Es por ello que en la práctica médica se ha definido un procedimiento de uso para normalizar lo mejor posible la fuerza del golpe. Este procedimiento define que el mango del martillo se toma entre los dedos pulgar e índice de la mano dominante del examinador y mediante un giro de muñeca, el martillo debe describir un arco amplio y debe caer por la fuerza de gravedad sobre la superficie a explorar en forma firme y directa. Una vez que el martillo impacte la superficie, debe retirarse rápidamente. In the case of the patellar reflex and the Aquilian reflex, the doctor observes the amplitude of the reflex response that results from hitting the tendon with the reflex hammer. However, the amplitude of the reflex response is a function of the force with which the stimulus is applied. That is why in medical practice a procedure of use has been defined to normalize the force of the blow as much as possible. This procedure defines that the hammer handle is taken between the thumb and index fingers of the examiner's dominant hand and by a wrist turn, the hammer must describe a wide arc and must fall by the force of gravity on the surface to be explored in firm and direct way. Once the hammer hits the surface, it must be removed quickly.
Sin embargo, no existe una retro alimentación sencilla y rápida para que el profesional evalúe si aplicó de manera correcta o no el estímulo. However, there is no simple and fast retro feeding for the professional to evaluate whether or not he applied the stimulus correctly or not.
Por otra parte, para el profesional resulta de interés conocer otras características del reflejo tales como la latencia, es decir el tiempo que transcurre entre la aplicación del estímulo y el comienzo del movimiento reflejo. Disponer de una
señal fiable y en tiempo real del momento en que se aplica el estímulo resulta de interés para complementar otros dispositivos que sirven para evaluar la amplitud del' reflejo. On the other hand, it is interesting for the professional to know other characteristics of the reflex such as latency, that is, the time that elapses between the application of the stimulus and the beginning of the reflex movement. Have a Reliable and real-time signal of the moment in which the stimulus is applied is of interest to complement other devices that serve to assess the amplitude of the 'reflex.
La presente invención permite retroalimentar al profesional en forma inmediata y confiable respecto de la manera en que fue aplicado el estímulo, a la vez que entrega información adicional para aplicaciones complementarias. The present invention allows feedback to the professional immediately and reliably with respect to the manner in which the stimulus was applied, while providing additional information for complementary applications.

The present invention incorporates sensors, microcontrollers, cable or wireless transmission devices and batteries in the same reflex hammer, without this embedding significantly changing its weight or shape.
La invención tiene como componentes una electrónica de adquisición de datos de aceleraciones, la implementación de algoritmos de extracción de la información a partir de dichos datos y los elementos para entregar al profesional la información relevante mediante componentes visuales o auditivos. The invention has as components an electronic acceleration data acquisition, the implementation of algorithms for extracting information from said data and the elements for delivering the relevant information to the professional through visual or auditory components.

La figura número 1 muestra el martillo que en la parte superior del mango contiene un sensor (1) conectado mediante cables que van internamente por la parte medía del mango (2). Un led (3) se usa para indicar que el martillo cayó por la fuerza de gravedad y un arreglo de luces (4) indica la intensidad del golpe.

Figure number 1 shows the hammer that contains a sensor (1) in the upper part of the handle connected by cables that go internally through the middle part of the handle (2).

Mejores maneras de realizar la invención Better ways to realize the invention
Al interior de la cabeza de un martillo estándar se coloca un acelerómetro MEMS que cuenta con una salida análoga o numérica. El acelerómetro es conectado a su vez a un microcontrolador que tiene integrado un conversor análogo digital o bien una interfaz de comunicaciones de datos para comunicarse con el acelerómetro MEMS. Los datos del acelerómetro son procesados por el microcontrolador con un algoritmo de análisis de señales. Inside the head of a standard hammer is placed a MEMS accelerometer that has an analog or numerical output. The accelerometer is in turn connected to a microcontroller that has integrated a digital analog converter or a data communications interface to communicate with the MEMS accelerometer. The accelerometer data is processed by the microcontroller with a signal analysis algorithm.
El algoritmo de análisis de señales que ejecuta el microcontrolador esta programado para detectar dos tipos de eventos. El primer evento es la caída libre del martillo cuyo elemento distintivo es la medida de valores de aceleración cercanos a cero. El segundo evento es el golpe cuya señal es una brusca desaceleración. En este último evento el microcontrolador registra el valor máximo de la desaceleración. The signal analysis algorithm that the microcontroller executes is programmed to detect two types of events. The first event is the free fall of the hammer whose distinctive element is the measurement of acceleration values close to zero. The second event is the blow whose signal is a sharp deceleration. In this last event, the microcontroller records the maximum deceleration value.
Cuando se detecta caída libre, un LED que está fijado en el mango del martillo se enciende. When free fall is detected, an LED that is fixed on the hammer handle lights up.
Cuando se detecta un golpe, el microcontrolador comanda el encendido de un arreglo de LED que representa la escala de intensidad del golpe. Por ejemplo, enciende el LED superior del arreglo cuando el golpe es superior al máximo predeterminado, el LED inferior si el golpe ha sido de baja intensidad, un LED intermedio cuando el golpe es de una intensidad que ha sido definida como normal. When a blow is detected, the microcontroller commands the lighting of an LED array that represents the intensity scale of the blow. For example, it turns on the upper LED of the array when the stroke is greater than the predetermined maximum, the lower LED if the stroke has been of low intensity, an intermediate LED when the stroke is of an intensity that has been defined as normal.
Paralelamente al encendido de los LED, una interfaz serial o un transmisor inalámbrico que está incrustado en el martillo, envía una cadena de datos que puede ser capturada por un receptor externo independiente. Parallel to the lighting of the LEDs, a serial interface or a wireless transmitter that is embedded in the hammer, it sends a data string that can be captured by an independent external receiver.
Aplicación industrial Industrial application
La manera en que se propone que la invención sea utilizada, es principalmente por parte de los médicos para que la evaluación de las estructuras neurológicas
periféricas con la integración medular central mediante los reflejos patelar y aquiliano sea estandarizada, al permitir este martillo estandarizar la fuerza con la cual se golpea el tendón. Este martillo puede también conectarse a un dispositivo electrónico para medir de manera objetiva el reflejo patelar, enviando una señal para que dicho dispositivo, objeto de la solicitud de patente en Chile n° 707-2010, esté sincronizado con el golpe. The way in which it is proposed that the invention be used, is mainly by doctors for the evaluation of neurological structures peripheral with the central spinal integration through the patellar and aquilian reflexes to be standardized, by allowing this hammer to standardize the force with which the tendon is struck. This hammer can also be connected to an electronic device to objectively measure the patellar reflex, sending a signal so that said device, object of the patent application in Chile No. 707-2010, is synchronized with the blow.
Originalidad de la invención Originality of the invention.
La originalidad de la invención consiste en que, a la vez que se mantiene sin mayores alteraciones la geometría y el peso del martillo de reflejos, se obtiene una retroalimentación instantánea, sencilla y precisa para que el profesional aumente la fiabilidad de la evaluación de la respuesta refleja. The originality of the invention is that, while maintaining the geometry and weight of the reflex hammer without major alterations, instant, simple and precise feedback is obtained so that the professional increases the reliability of the response evaluation reflects.
De esta manera se diferencia de martillos médicos que incorporan algún tipo de instrumentación pero que no ofrecen información procesada al profesional. Se diferencia también de los martillos industriales que incorporan acelerómetros pero que no están diseñados para uso médico y/o que entregan datos en forma de gráficos para su posterior interpretación pero no lo hacen de manera instantánea y simple.
In this way, it differs from medical hammers that incorporate some type of instrumentation but do not offer processed information to the professional. It also differs from industrial hammers that incorporate accelerometers but are not designed for medical use and / or that provide data in the form of graphs for later interpretation but do not do so instantly and simply.
