Description

DISPOSITIVO PARA LA MONITORIZACIÓN DE LAS ALOPECIAS  DEVICE FOR MONITORING OF ALOPECIES
CAMPO DE LA INVENCIÓN FIELD OF THE INVENTION
La presente invención se refiere al campo técnico de la dermatología, y más concretamente a las técnicas y dispositivos para la monitorización y el estudio de la evolución de la alopecia o caída del cabello. The present invention relates to the technical field of dermatology, and more specifically to the techniques and devices for monitoring and studying the evolution of alopecia or hair loss.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Dentro del campo médico de la dermatología, la medida objetiva del curso de las alopecias sigue siendo, aún en la actualidad, una tarea sujeta a un grado considerable de imprecisión, dado que la mayoría de ocasiones no se realiza un seguimiento objetivo mediante sistemas de medida o, en los casos de seguimiento fotográfico o mediante escalas de gravedad de la alopecia, la exactitud de la medida depende de la habilidad o experiencia del médico en la realización de dicha medida. Within the medical field of dermatology, the objective measurement of the course of alopecia remains, even today, a task subject to a considerable degree of inaccuracy, given that in most cases an objective follow-up is not carried out through measurement systems or, in cases of photographic follow-up or by means of severity scales of alopecia, the accuracy of the measure depends on the skill or experience of the physician in performing said measurement.
Cuando los pacientes van perdiendo el cabello gradualmente, y la línea de implantación del pelo retrocede a lo largo de los años, el mejor método para efectuar el seguimiento de la evolución de la alopecia es realizar una medida desde dicha línea de implantación del pelo hasta el entrecejo o hasta la cola de la ceja. Esta medida se realiza también con el objetivo de estudiar la respuesta del paciente ante tratamientos anti-caída. Dada la falta de dispositivos diseñados a tal efecto, lo habitual es que no se realice un seguimiento preciso de la evolución de las alopecias. En los casos en los que se realiza, se suele emplear una regla milimetrada aplicada al paciente de forma manual, y donde la exactitud de la medida puede variar en función del punto de partida de la medida y de la pericia del profesional. When patients gradually lose their hair, and the hair implantation line recedes over the years, the best method to monitor the evolution of alopecia is to measure from the hair implantation line to the hair eyebrows or up to the tail of the eyebrow. This measure is also carried out with the objective of studying the patient's response to anti-fall treatments. Given the lack of devices designed for this purpose, it is usual not to accurately track the evolution of alopecia. In the cases in which it is performed, a millimeter ruler applied to the patient is usually used manually, and where the accuracy of the measurement may vary depending on the starting point of the measurement and the professional's expertise.
No obstante, dadas las variaciones morfológicas naturales que presenta cada paciente en la posición de sus cejas, junto con la poca flexibilidad de las reglas empleadas, posibles movimientos de la regla con la consiguiente pérdida de precisión, o por la ausencia de fijación del cabello y de la regla para realización de las medidas, existe, en la práctica, una necesidad dentro de este campo, de desarrollar nuevos procedimientos o dispositivos de medida que mejoren las propuestas del estado de la técnica. La presente invención está orientada a resolver dicha necesidad. DESCRIPCIÓN BREVE DE LA INVENCIÓN However, given the natural morphological variations that each patient presents in the position of their eyebrows, together with the little flexibility of the rules used, possible movements of the rule with the consequent loss of precision, or the absence of hair fixation of the rule for carrying out the measures, there is, in practice, a need within this field, to develop new procedures or measuring devices that improve the proposals of the prior art. The present invention is aimed at solving said need. BRIEF DESCRIPTION OF THE INVENTION

En una realización preferente de la invención, el medio de soporte del dispositivo comprende una diadema, más preferentemente adaptada al arco bitragial de la cabeza. Se consigue con ello permitir el desplazamiento del cabello (en los casos en que el/la paciente tenga el cabello largo) hacia detrás, de tal forma que no impide la correcta valoración de la medida a registrar, ni impida la correcta visualización de esta medida, por ejemplo al tomar fotografías. La diadema resulta, además, cómoda para su colocación en la cabeza del paciente, siendo menos incómoda que, por ejemplo, un sistema basado en un casco cubriendo la totalidad de la cabeza. In a preferred embodiment of the invention, the support means of the device comprises a headband, more preferably adapted to the bitragial arch of the head. This is achieved by allowing the hair to move (in cases where the patient has long hair) backwards, in such a way that it does not prevent the correct assessment of the measure to be recorded, nor does it impede the correct display of this measure. , for example when taking pictures.

In another preferred embodiment of the invention, the alopecia measuring means of the device are located on one or more sides of the adaptable support means and, more preferably, said measuring means are configured to be arranged on the sagittal arch of the head. This achieves a suitable reference line for measuring the evolution of alopecia, which conforms to the methodologies commonly used in the state of the art, but avoiding the disadvantages that they present (inaccuracy and subjectivity, lack of subjection to the head, etc.) In a preferred embodiment of the invention, the measuring means comprise one or more rectangular millimeter rulers, and more preferably said means are configured to adapt to the shape of the head along a part or all of the region comprised from the hair implantation line to the tail of the eyebrow or frown. This achieves an easily usable device, which also has the advantage of being used to measure the evolution of alopecia over various reference points in the patient's head.
En una realización preferente de la invención, los medios de acoplamiento del dispositivo comprenden un sistema de clipaje o uno o más medios adhesivos y, más preferentemente, dichos medios de acoplamiento son medios de acoplamiento regulables, configurados para permitir posiciones variables de los medios de medición en su punto de conexión con el medio de soporte. Se consigue con ello un dispositivo de gran adaptabilidad a las diversas formas y tamaños de la cabeza de los pacientes. In a preferred embodiment of the invention, the coupling means of the device comprise a clipping system or one or more adhesive means and, more preferably, said coupling means are adjustable coupling means, configured to allow variable positions of the measuring means. at its point of connection with the support medium. This achieves a device that is highly adaptable to the various shapes and sizes of patients' heads.
En otra realización preferente de la invención, el material del medio de soporte y/o de los medios de medición del dispositivo es un material transparente. Se consigue con ello un dispositivo fácilmente utilizable en combinación con técnicas de medición fotográfica o videográfica de la alopecia, permitiendo la captura de imágenes también de las zonas de la cabeza sobre las que se dispone el dispositivo. In another preferred embodiment of the invention, the material of the support means and / or the measuring means of the device is a transparent material. This achieves an easily usable device in combination with photographic or videographic measurement techniques of alopecia, allowing images to be captured also from the head areas on which the device is arranged.
