Abstract
Description
Išradimas skirtas medicinos ir sporto technikos sričiai, t.y. žmogaus kūno šildymas, šaldymas gydymo tikslu, taip pat sportininkų raumenų šildymui arba šaldymui, siekiant paruošti raumenį fiziniam darbui, atstatyti darbingumų po didelių fizinių krūvių.The invention relates to the field of medical and sports equipment, i.e. heating of the human body, refrigeration for therapeutic purposes, as well as the heating or refrigeration of athletes' muscles to prepare them for physical exercise, to restore their fitness after heavy physical exertion.
Žinomas prietaisas, susidedantis iš keleto termoelektrinių modulių (TEM), sujungtų į bendrą visumą ir vienodai veikiantis visą raumens plotą (žiūr. patentą SU 1674834 Al, publikuotą 1991.09.07 ). Tokio prietaiso trūkumas - nėra galimybės atskirai veikti gretimas raumenų grupes.Known device consisting of several thermoelectric modules (TEMs) connected in a single whole and operating uniformly over the whole muscle area (see patent SU 1674834 Al, published 07.09.1991). The disadvantage of such a device is that it is not possible to separately operate adjacent muscle groups.
Artimiausias iš analogų yra prietaisas, susidedantis iš dviejų TEM, su įmontuotu temperatūros davikliu ir valdomas temperatūros reguliatoriumi (žiūr. patentą RU 2033776, publikuotą 1995.04.30). Prietaiso trūkumas - TEM valdomi vienu bendru temperatūros reguliatoriumi, remiantis vieno temperatūros daviklio duomenimis, dėl ko nėra galimybės atskirai veikti gretimas raumenų grupes.The closest of the analogs is a device consisting of two TEMs with a built-in temperature sensor and controlled by a temperature controller (see patent RU 2033776, published April 30, 1995). The drawback of the device is that the TEMs are controlled by a single temperature controller based on the data from a single temperature sensor, which makes it impossible to operate adjacent muscle groups individually.
Išradimo tikslas-funkcinių galimybių išplėtimas.The object of the invention is the extension of functional possibilities.
Žmogaus raumens šildymo-šaldymo įrenginys, susidedantis iš kelių TEM, bei temperatūros daviklio ir temperatūros reguliatoriaus. Nauja yra tai, kad kiekvienas TEM turi po du temperatūros daviklius su prie kiekvieno iš jų prijungtu temperatūros matavimo bloku, keitikliu “analogas-kodas” ir sujungtas su personalinio kompiuterio duomenų įvedimo-išvedimo jungtimi (LPT), kuris per tą pačią jungtį sujungtas su keitikliu “kodas-analogas”, impulso pločio moduliatoriumi ir TEM, be to tarp abiejų temperatūros davikių įmontuotas šilumos izoliatorius, kuris naudojamas šilumos srauto į raumenį matavimui.Human muscle heating and cooling device consisting of several TEMs, as well as a temperature sensor and a temperature controller. What's new is that each TEM has two temperature sensors with a temperature measuring unit connected to each of them, an analog-to-code converter and connected to a PCT data input-output connector (LPT) which is connected to the converter via the same connector A "code-to-analog" pulse-width modulator and TEM, and a thermal insulator between both temperature sensors, which is used to measure heat flow to the muscle.
Fig.l pavaizduota šildymo-šaldymo įrenginio blokinė schema, fig.2- konstrukcija šilumos srauto matavimui.Fig. 1 is a block diagram of a heating and cooling unit, Fig. 2 is a design for measuring heat flow.
Šildymo-šaldymo įrenginio blokinė schema - personalinis kompiuteris 1, keitiklis “kodas-analogas” 2, impulso pločio moduliatorius 3, galios stiprinimo laipsnis 4, keitiklis analogas-kodas 5, pirmas temperatūros matavimo blokas 6, TEM 7, pirmas temperatūros daviklis 8, antras temperatūros matavimo blokas 9, antras temperatūros daviklis 10. Konstrukcija šilumos srauto matavimui -TEM 7, pirmas temperatūros daviklis 8, antras temperatūros daviklis 10, šilumos izoliatorius 11.Block diagram of heating and cooling unit - PC 1, code-to-analog converter 2, pulse-width modulator 3, power amplification degree 4, analog-to-code converter 5, first temperature measuring unit 6, TEM 7, first temperature sensor 8, second temperature measuring unit 9, second temperature sensor 10. Construction of heat flow measurement -TEM 7, first temperature sensor 8, second temperature sensor 10, heat insulator 11.
Temperatūros davikliais 8 ir 10, temperatūros matavimo blokais 6 ir 9 pamatuota temperatūra per keitiklį “analogas-kodas” 5 įvedama į personalinį kompiuterį 1. Kompiuterio programa, įvertinusi pamatuotą temperatūrą, nustatytą temperatūrą ir eilę kitų faktorių, išduoda signalą TEM valdymui.Šis skaitmeninis signalas keitiklyje “kodas-analogas” 2 verčiamas į analoginį signalą. Analoginis signalas valdo impulso pločio moduliatorių 3, toliau patenka į galios stiprinimo laipsnį 4 ir TEM 7. Panaudotas impulsinės moduliacijos principas padidina TEM valdymo naudingumo koeficientą. Konstruktyviai, prie apatinės TEM 7 dalies betarpiškai montuojamas temperatūros daviklis 8. Po juo eina šilumos izoliatorius 11 su žinomu šiluminio laidumo koeficientu. Po izoliatoriumi yra įmontuotas antras temperatūros daviklis 10. Pirmasis daviklis matuoja šildymo arba šaldymo temperatūrą, antrasis - odos temperatūrą poveikio zonoje. Izoliatorius 11 naudojamas energijos srauto matavimui. Kadangi šis elementas yra įjungtas nuosekliai visam energijos srautui, tai, žinant jo parametrus ir pasinaudojant Furje formule, galima paskaičiuoti šilumos srautą per minėtą izoliatorių į raumenį (arba raumens energijos sugėrimo spartą):Temperature sensors 8 and 10, temperature units 6 and 9 measure the temperature via the converter "analog-code" 5 into a personal computer 1. The computer program, after evaluating the measured temperature, set temperature and a number of other factors, provides a signal for TEM control. in the code-to-analog converter 2 it is converted to an analog signal. The analog signal controls the pulse width modulator 3, then goes to power gain level 4 and TEM 7. The applied pulse modulation principle increases the efficiency of the TEM control. Constructively, a temperature sensor 8 is mounted directly on the lower part of the TEM 7. Below it is a thermal insulator 11 with a known thermal conductivity. Underneath the insulator is a second temperature sensor 10. The first sensor measures the heating or cooling temperature, the second one measures the skin temperature in the affected area. The insulator 11 is used to measure the energy flow. Since this element is switched on sequentially for the entire energy flow, knowing its parameters and using the Fourier formula, it is possible to calculate the heat flux through said insulator to the muscle (or muscle energy absorption rate):
D = kxA*AT/Ax, čia: D -šilumos srautas [J/s], k - šiluminio laidumo koeficientas [J/s/m°C], A - plotas, per kurį registruojamas šilumos srautas [m2], ΔΤ - temperatūrų skirtumas tarp šalto ir šilto paviršiaus[°C], Δχ - dielektriko storis [m].D = kxA * AT / Ax, where: D is the heat flux [J / s], k is the thermal conductivity [J / s / m ° C], A is the area over which the heat flux is recorded [m 2 ], ΔΤ - temperature difference between cold and warm surface [° C], Δχ - dielectric thickness [m].
