摘要：
The utility model refers to the field of medical technology, in particular, to devices for collecting and treating wound blood of a patient during an operation to return it to the bloodstream of the patient and reduce the need for donor blood.The technical task is to create a device protected from external interference, which allows timely detection of air bubbles in liquid lines.The technical result is to improve the reliability of the collection device and to monitor the state of the treated blood.The technical result is achieved due to the fact that the blood collection device comprising a vacuum pump, a separator, a control unit, a compressor and a line located in the housing is provided with an adapter tube and an air bubble sensor. The air bubble sensor is made in a single housing with a groove to accommodate the adapter tube and a protrusion protecting the adapter tube from external background radiation, an infrared LED, a photodiode and a microprocessor are installed inside the sensor housing. The tube-adapter is installed in the groove in the sensor housing and is designed to interact with lines of different sizes. The infrared LED is connected to the microprocessor and is configured to operate in intermittent mode. The photodiode is connected to the microprocessor and is configured to fix the presence or absence of an air bubble in the treated liquid based on the presence or absence of an infrared light signal from the infrared LED. The microprocessor is made in the form of a complex-component electronic board with an integrated voltage regulator and is connected by its input to the output of the photodiode, and the output is connected to the input of an infrared LED.Полезная модель относится к области медицинской техники, в частности к устройствам для сбора и обработки раневой крови пациента во время операции с целью ее возвращения в кровеносное русло пациента и снижения потребности в донорской крови.Техническая задача заключается в создании защищенного о
