Abstract
Description
Dispositif et procédé de photothérapie. Phototherapy device and method.
La présente invention se rapporte à un dispositif de photothérapie destiné à l'émission d'énergie lumineuse en direction de la peau d'un patient, en vue par exemple du traitement photothérapeutique ou photochimiothérapeutique des dermatoses. The present invention relates to a phototherapy device intended for the emission of light energy in the direction of the skin of a patient, with a view for example to phototherapeutic or photochemotherapeutic treatment of dermatoses.
D'une manière connue, les traitements de ce genre sont effectués en utilisant un espace pouvant avoir la forme #'une cabine à l'intérieur de laquelle se place le patient, les parois de la cabine comportant des tubes émetteurs verticaux répartissant l'énergie tout autour et sur toute la hauteur du patient. La conduite d'un traitement, pour une affection donnée, est caractérisée par une succession de séances dont l'espacement est déterminé, la quantité d'énergie reçue par le patient lors de chaque séance devant être dosée avec précision.A l'heure actuelle, les cabines comportent un seul et même type de tubes émetteurs d'un rayonnement d'un type défini :UVA, UVB,..., le traitement consistant, à chaque séance, à soumettre le patient soit à un seul type déterminé de rayonnement, pendant un temps prédéfini, soit à des séquences de plusieurs radiations, soit enfin à des séances comportant plusieurs radiations. In a known manner, the treatments of this kind are carried out using a space which can have the form # 'a cabin inside which the patient is placed, the walls of the cabin comprising vertical emitting tubes distributing the energy all around and over the entire height of the patient. The conduct of treatment for a given condition is characterized by a succession of sessions, the spacing of which is determined, the amount of energy received by the patient during each session having to be precisely measured. , the cabins have one and the same type of radiation emitting tubes of a defined type: UVA, UVB, ..., the treatment consisting, at each session, in subjecting the patient either to a single determined type of radiation , for a predefined time, either at sequences of several radiations, or finally at sessions comprising several radiations.
Le dispositif de photothérapie de l'invention a pour objet de permettre la mise en oeuvre d'une thérapeutique à photothérapie qui est entièrement nouvelle, combinant, à l'aide d'une seule "cabine" et au cours d'une seule et même séance, plusieurs types de rayonnements différents appliqués successivement ou simultanément. Il est caractérisé en ce qu'il comporte plusieurs lampes, tubes ou groupes de lampes ou tubes d'émission de rayonnements de types différents (UVA,UVB, rayons actiniques...), et en ce qu'il est équipé de moyens de programmation permettant de déterminer avec précision l'instant de départ et de la durée d'émission de chaque tube ou lampe, ou groupe de tubes ou lampes, au cours d'une même séance de photothérapie. The object of the phototherapy device of the invention is to allow the implementation of a phototherapy therapy which is entirely new, combining, using a single "cabin" and in the course of a single and same session, several different types of radiation applied successively or simultaneously. It is characterized in that it comprises several lamps, tubes or groups of lamps or radiation emission tubes of different types (UVA, UVB, actinic rays, etc.), and in that it is equipped with means for programming allowing precise determination of the start time and duration of emission of each tube or lamp, or group of tubes or lamps, during the same phototherapy session.
Grâce à la programmation qui permet de moduler les émissions des différentes longueurs d'onde, il est ainsi possible d'obtenir le résultat thérapeutique optimal, en supprimant ou au moins en diminuant le risque carcinogène des ultraviolets, tout en dispensant un minimum d'énergie. A cet effet, l'invention se rapporte aussi à un procédé de photothérapie, caractérisé en ce qu'il consiste à moduler l'énergie émise, et son temps d'émission pendant une séance, en fonction du temps total programmé pour cette séance. Thanks to the programming which makes it possible to modulate the emissions of the different wavelengths, it is thus possible to obtain the optimal therapeutic result, by eliminating or at least reducing the carcinogenic risk of ultraviolet rays, while dispensing a minimum of energy. . To this end, the invention also relates to a phototherapy process, characterized in that it consists in modulating the energy emitted, and its emission time during a session, as a function of the total time programmed for this session.
L'invention sera mieux comprise à l'aide de la description suivante d'un exemple de réalisation, en référence à la figure unique annexée, qui est une représentation très schématique d'un dispositif selon l'invention. The invention will be better understood with the aid of the following description of an exemplary embodiment, with reference to the appended single figure, which is a very schematic representation of a device according to the invention.
Sur la figure, on a désigné par la référence I la cabine, ou autre espace émissif, à l'intérieur de laquelle prendra place le patient. Comme toutes les cabines de ce type, elle comporte sur ses parois des tubes verticaux d'émission de rayons pour photothérapie, mais, conformément à un aspect de l'invention, ces tubes ne sont pas tous identiques, mais comportent successivement répartis sur le pourtour de la cabine
- un groupe 2 de deux tubes de rayonnement UVA alimentés en parallèle en 3,
- un groupe 4 de deux tubes à rayonnement UVB alimentés en parallèle en 5,
- un groupe 6 de deux tubes à rayons actiniques alimentés en parallèle en 7,
- à nouveau un groupe de deux tubes 8 à rayons UVA alimentés en parallèle en 9, et ainsi de suite sur tout le pourtour de la cabine 1.In the figure, the reference I has designated the cabin, or other emissive space, inside which the patient will sit. Like all cabins of this type, it has on its walls vertical radiation tubes for phototherapy, but, according to one aspect of the invention, these tubes are not all identical, but have successively distributed around the periphery from the cabin
- a group 2 of two UVA radiation tubes supplied in parallel at 3,
- a group 4 of two UVB radiation tubes supplied in parallel at 5,
- a group 6 of two actinic ray tubes supplied in parallel at 7,
- again a group of two tubes 8 with UVA rays supplied in parallel at 9, and so on all around the cabin 1.
Par ailleurs, un micro-ordinateur 10, ou un calculateur à microprocesseur, ou analogue, relié à une interface 11 comportant en particulier des amplificateurs et au moins un relais par groupe 2,4,6,8..., de tubes permet la mise en route, au cours d'une même séance, d'un ou plusieurs groupes de tubes d'émission d'un premier type de rayonnement, par exemple
UVA, pendant un premier temps prédéterminé, par exemple dix minutes, puis la mise en route d'un ou plusieurs groupes de tubes d'émission d'un deuxième type de rayonnement, par exemple UVB, pendant un deuxième temps prédéterminé, par exemple quatre minutes, puis la mise en route d'un ou plusieurs groupes de tubes d'émission d'un troisième type de rayons, par exemple des rayons actiniques, pendant un troisième temps prédéterminé, par exemple six minutes, et ainsi de suite éventuellement jusqu'à la fin de la séance, cellewi étant entièrement guidée par le micro-ordinateur 10 en fonction du programme préenregistré et sélectionné par ltopérateur à l'aide de son clavier 12.Furthermore, a microcomputer 10, or a microprocessor-based computer, or the like, connected to an interface 11 comprising in particular amplifiers and at least one relay per group 2,4,6,8 ..., of tubes allows the starting, during the same session, one or more groups of emission tubes of a first type of radiation, for example
UVA, for a first predetermined time, for example ten minutes, then starting one or more groups of emission tubes of a second type of radiation, for example UVB, for a second predetermined time, for example four minutes, then switching on one or more groups of emission tubes of a third type of ray, for example actinic rays, for a third predetermined time, for example six minutes, and so on, possibly up to at the end of the session, the session being entirely guided by the microcomputer 10 as a function of the pre-recorded program and selected by the operator using his keyboard 12.
Un certain nombre de programmes de séance ainsi panachées en rayons et en temps et puissances de rayonnement, définissant un nombre égal de types de traitement, ayant été introduits dans la mémoire du micro-ordinateur 10, l'auxiliaire médical n'a plus, en fonction de l'ordon nance du médecin spécialiste définissant le type de programme à appliquer pour la séance considérée, qu'à taper le code du programme indiqué sur le clavier 12 du micro-ordinateur 10. A certain number of session programs thus variegated in rays and in time and radiation powers, defining an equal number of types of treatment, having been introduced into the memory of the microcomputer 10, the medical assistant no longer has, in function of the order of the specialist doctor defining the type of program to be applied for the session in question, than by typing the code of the program indicated on the keyboard 12 of the microcomputer 10.
Le micro-ordinateur 10 est donc un organe de calcul et de commande dont l'usage est supérieur au simple calcul de l'énergie, celui-ci servant au pilotage de chaque séance et adaptant l'énergie émise et le temps d'émission de cette énergie à la longueur de ladite séance. The microcomputer 10 is therefore a calculating and controlling member, the use of which is greater than the simple calculation of the energy, the latter being used for controlling each session and adapting the energy emitted and the emission time of this energy the length of the session.
A l'instar de tubes, l'espace émissif peut également être doté de lampes produisant tous les ultra-violets. La sélection des différentes longueurs d'ondes se fait, dans ce cas, grâce à des filtres (permettant l'application des UVA, UVB et rayons actiniques qui sont pilotés par le micro-ordinateur suivant le programme prévu ci-dessus. Like tubes, the emissive space can also be fitted with lamps producing all ultraviolet light. The selection of the different wavelengths is done, in this case, thanks to filters (allowing the application of UVA, UVB and actinic rays which are controlled by the microcomputer according to the program provided above.
Un intérêt important de l'invention réside dans la possibilité d'économiser la dépense d'énergie, en modulant l'énergie émise pendant une séance en fonction du temps total programmé de cette séance. Par exemple, une énergie de 5 joules UVA qui pourrait être dispensée par la cabine normalement en environ 5 minutes, sera remplacée par une énergie de 3 joules dispensée en 9 minutes, le résultat thérapeutique étant équivalent, mais le danger pour le malade diminuant d'autant. An important advantage of the invention lies in the possibility of saving energy expenditure, by modulating the energy emitted during a session as a function of the total programmed time of this session. For example, an energy of 5 joules UVA which could be dispensed by the cabin normally in about 5 minutes, will be replaced by an energy of 3 joules dispensed in 9 minutes, the therapeutic result being equivalent, but the danger for the patient decreasing as much.
