Abstract

The invention relates to a micro-sensor glove meant to evaluate the stage of medical recovery at the level of the upper limb. According to the invention, the glove comprises a piezoelectric micro-senor (1) attached by means of an adhesive on the dermal papillae region on the fingers of a medical glove (3), each micro-sensor including a piezoelectric plate (6) and a metal disk (5) and being protected by means of some supports (2) made of silicone rubber, where the micro-sensors (1), by means of some connections (4), are coupled with a data acquisition system or an oscilloscope, in case of tests or laboratory experiments.

Description

Invenția se referă la o mănușă cu microsenzori utilizată în evaluările pacienților după procedurile specifice de recuperare medicală pentru membrul superior.The invention relates to a microsensor glove used in evaluating patients following specific medical recovery procedures for the upper limb.

Sunt cunoscute modurile de evaluare ale stării unui pacient după perioadele în care acesta este supus unor proceduri specifice de recuperare medicală în care evaluarea este stabilită de medic după o analiză în care pacientul este supus unor mișcări de pensă (alternativ cu contacte succesive între degete sau după cum țin un obiect între degete etc.).The methods of evaluating the condition of a patient are known after the periods when he is subjected to specific medical recovery procedures in which the evaluation is established by the doctor after an analysis in which the patient is subjected to movements of the forceps (alternatively with successive contacts between the fingers or after how to hold an object between your fingers, etc.).

Dezavantajele unor astfel de evaluări, constau în;The disadvantages of such evaluations are:

Evaluarea se face de către un medic cu specialitatea de recuperare medicală, prin observarea mișcării de contact între degete (pensă), sau din diferite mișcări care trebuie efectuate conform unor proceduri, dar care sînt apreciate numai vizual.The evaluation is done by a doctor with the specialty of medical recovery, by observing the movement of contact between the fingers (forceps), or from different movements that must be performed according to some procedures, but which are appreciated only visually.

Problema pe care o rezolvă invenția este aceea că mișcările de contact între degete cît si alte proceduri specifice sînt monitorizate la nivelul forțelor de contact dintre degete sau al forțelor care apar la mînuirea unor obiecte. Astfel aceste forte pot fi puse in evidentă, evaluând procedura de recuperare medicală la modul cantitativ, evidențiindu-se valoarea forțelor, timpii de răspuns, modul de corelare al mișcărilor degetelor mult mai exact, in concluzie cu o precizie ridicată si cu o tehnologie simplă.The problem solved by the invention is that the contact movements between the fingers and other specific procedures are monitored at the level of the contact forces between the fingers or the forces that appear when handling objects. Thus, these forces can be highlighted, evaluating the medical recovery procedure quantitatively, highlighting the value of the forces, the response times, the way of correlating the movements of the fingers more precisely, in conclusion with a high precision and with a simple technology.

Mănușa cu microsenzori conform inveniei înlătură dezavantajele de mai sus prin aceea că în scopul evaluării stadiului de recuperare medicală la nivelul membrului superior, cuprinde câte un microsenzor piezoelectric, fiecare microsenzor este protejat de efectele distructive ale unor solicitări mecanice accidentale prin intermediul unor suporți din cauciuc siliconic care acoperă microsenzorii, microsenzorii fiind fixați cu ajutorul unor adezivi pe papilele degetelor unei mănuși medicale si de la fiecare senzor existînd cîte două conexiuni; o structură a microsenzorului piezoelectric include discul suport metalic, pastila piezoelectrică cu un diametru între 5-10 mm, si grosime 0,10,3mm, pe partea superioară a pastilei existînd un electrod realizat prin depunere metalică (de preferat argintul), cu o grosime nu mai mare de 0,05-0,1 mm, conexiunile mergând la sistemul de achiziție de date sau la osciloscop în cazul unor investigații sau experimente de laborator.The microsensor glove according to the invention removes the above disadvantages by the fact that in order to evaluate the medical recovery stage at the upper limb, it comprises a piezoelectric microsensor, each microsensor is protected from the destructive effects of accidental mechanical stresses by means of silicone rubber supports. which covers the microsensors, the microsensors being fixed with the help of adhesives on the finger papillae of a medical glove and from each sensor having two connections; a structure of the piezoelectric microsensor includes the metal support disc, the piezoelectric pillar with a diameter between 5-10 mm, and a thickness of 0.10,3mm, on the upper part of the pillar there is an electrode made by metal deposition (preferably silver), with a thickness not more than 0,05-0,1 mm, the connections going to the data acquisition system or to the oscilloscope in case of investigations or laboratory experiments.

Mănușa cu microsenzori conform invenției prezintă următoarele avantaje:The microsensor glove according to the invention has the following advantages:

- Evaluarea după procedurile de recuperare medicală a membrului superior este mult mai precisă,- The evaluation according to the medical recovery procedures of the upper limb is more accurate,

- Reprezintă o soluție simplă,- It is a simple solution,

- Se poate adapta ușor la orice procedură de evaluare in vederea identificării stagiului de recuperare al membrelor superioare.- It can be easily adapted to any evaluation procedure in order to identify the recovery stage of the upper limbs.
