Изобретение относитс к технической физике, а именно к области техники, предназначенной дл измерени слабых свечений биологических объектов, и может быть использовано в биологии и медицине дл оценки т жести патологи- , ческого. состо ни организма.The invention relates to technical physics, in particular to the field of technology intended to measure the faint luminescence of biological objects, and can be used in biology and medicine to assess the severity of pathological. state of the organism.
Один из известных способов измерени свечени биологических объектов осуществл етс путем измерени светового потока по системе сигнал плюс фон с, последующим вычитанием ,Q фона (1.One of the known methods for measuring the luminescence of biological objects is carried out by measuring the luminous flux through the system signal plus background c, followed by subtraction, Q background (1.
Наиболее близким техническим решением к изобретению вл етс способ измерени свечени биологических объектов в холодильнике с релейной системой термостабилизашш путем ,5 периодического измерени светового потока, испускаемого биологическим объек1ом, внутри холодильника 2.The closest technical solution to the invention is a method for measuring the luminescence of biological objects in a refrigerator with a thermostabilized relay system by, 5 periodically measuring the light flux emitted by the biological object inside the refrigerator 2.
В известном способе измерени световых ПОТОКОВ фои и сигнал плюс фон постуттают 20 непосредственно со .светоприемника Ш1 аппаратуру регистрации дискретно в фиксированные моменты времени, длительность которых задаетс реле времени. При этом в процессе регистрации происходит изменение фона и сигнала плюс фон из-за нестабильности температуры элементов светоприемника, св занное с изменением цикла работы холодильной машины, вследствие чего происходит иесинфазна регистраци величины фона и сигнала плюс фон, что приводит к ошибке измерени световых величин .In the well-known method of measuring light FLOWS, the foi and the signal plus the background are switched 20 directly from the light receiver Ш1 to the recording equipment discretely at fixed points in time, the duration of which is set by the time relay. In this case, the background and signal plus the temperature of the elements of the light-receiving device change due to the change in the operation cycle of the refrigerating machine, resulting in ineffective phase recording of the background and signal plus the background, which leads to measurement error of the light values.
Цель изобретени - повышение точности.The purpose of the invention is to improve accuracy.
Дл достижени указанной цели измерени светового потока осуществл ют в моменты включени системы термостабилизации холодильника .To achieve this goal, the measurement of the luminous flux is carried out at the moments of switching on the thermal stabilization system of the refrigerator.
На чертеже представлена структурна схема устройства, реализ)тощего предлагаемый способ.The drawing shows a block diagram of the device, implemented the lean method proposed.
Устройство содержит светозащитную камеру 1 с термоизол цией 2, внутрь камеры вставлен медный спиральный змеевик 3 между хладопроводом 4 и чувствительным элементом 5 термореле 6, которое соединено одновременно с пускозащитным реле 7 и электронным ключем 8 утфавлени аппаратуры 9 регистрации светового излучени , св занным электрически со светоприемником 10. Змеевик с помощьюThe device contains a light-shielding chamber 1 with thermal insulation 2, and a copper spiral coil 3 is inserted into the chamber between the cold pipeline 4 and the sensitive element 5 of the thermal relay 6, which is simultaneously connected to the start-up relay 7 and the electronic switch 8 of the optical radiation detection equipment 9 connected electrically to the light receiver 10.
