Description
Předmětem vynálezu je zařízeni pro fotostimulaci v oboru medicíny.The present invention provides photostimulation devices in the medical field.
Dosavadní fotostimulátory používají jako zdroje světla laser, jehož světelný výstup je veden ohebným světlovodem k místu aplikace.Previous photostimulators use a laser as a light source, the light output of which is led through a flexible light guide to the application site.
Nevýhodou tohoto řeěení jsou vysoké náklady a značné rozměry zařízeni, značná spotřeba energie, takže při provozu nezávislém na síti by bylo nutno použit výkonné elektrochemi-kó zdroje a dalěi nevýhodou je obtížná modulace výstupního světelného toku.The disadvantage of this solution is the high cost and the large dimensions of the equipment, the considerable power consumption, so that in network-independent operation it would be necessary to use powerful electrochemical sources and further disadvantage is the difficult modulation of the output luminous flux.
Výhodou zařízeni podle vynálezu jsou malé rozměry a nízké náklady.The advantage of the device according to the invention is its small size and low cost.
Podstata Zařízeni pro fotostimulaci v oboru medicíny spočívá v tom, že zdrojem světla je světelná dioda připojená k budícímu obvodu pro generováni impulsů konstantního proudu. K tomuto budícímu obvodu může být připojen indikátor poklesu napěti zdroje pro napájeni budicího obvodu.The principle of a photostimulation device in the medical field is that the light source is a light emitting diode connected to a driving circuit for generating constant current pulses. To this excitation circuit, a voltage drop indicator for the excitation circuit power supply may be connected.
Příklad provedeni zařízeni podle vynálezu je znázorněn na výkresepředstavujícím blokové schéma.An exemplary embodiment of the device according to the invention is shown in the drawing, which is a block diagram.
Světelná dioda 1 je přes budicí obvod 2 pro generováni impulsů konstantního proudu připojena ke zdroji 3 pro napájeni budicího obvodu 2. Ke zdroji 3 je rovněž připojen indikátor 4 poklesu napětí zdroje 3.The light-emitting diode 1 is connected to the power supply 3 for supplying the driving circuit 2 via a constant current pulse generating circuit 2. The voltage drop indicator 4 of the power supply 3 is also connected to the power supply 3.
Světelná dioda 4 dává dostatečný světelný výkon* který lze snadno modulovat. Při požadovaném světelném výkonu 1 až 2 mW lze sestrojit zařízeni s celkovým příkonem pod 1 W, takže'zařízeni lze provozovat z běžných baterii. Pro zajiětěni terapeutické účinnosti je nutno proud diody stabilizovat a přeruěovat, k čemuž slouží budicí obvod 2 pro generování impulsů konstantního budicího proudu. Indikátor 4 poklesu napěti zdroje 3 indikuje, zda napětí zdroje 3 pokleslo pod úroveň nutnou ke spolehlivé činnosti.LED 4 provides sufficient light output * which can be easily modulated. At the required light output of 1 to 2 mW, a device with a total power consumption of less than 1 W can be constructed so that the device can be operated from conventional batteries. In order to provide therapeutic efficacy, it is necessary to stabilize and interrupt the diode current, which is used by the drive circuit 2 to generate pulses of a constant drive current. The voltage drop indicator 4 of the power supply 3 indicates whether the voltage of the power supply 3 has dropped below the level necessary for reliable operation.
Vynález je možno s výhodou použít zejména pro terapii,aplikovanou ambulantně i případné doma.The invention can be advantageously used, in particular, for therapy applied both on an outpatient basis and possibly at home.
