Design Requirements for the Device for Differentiating Pathological States of Biological Tissues

Abstract

The appearance of the device for mini-gamma-quantum differentiation of biological tissues, the arrangement of units (research unit and control unit), units (cassette holder, electronic units, etc.) and individual parts (cassette, etc.), as well as control panels (front and rear) have ergonomic indicators that ensure convenience use (preparation for operation – ease of installation of the device on the table, connection to the electrical network and grounding, loading/unloading of biological tissue samples into/from the cassette, etc.); ease of use (ease of working with the control panel and the cassette with the cassette holder); the convenience of preventive maintenance work (cassette disinfection, etc.). The control unit and the research unit are located in different housings of the device: a) control unit – in a high-strength plastic case; b) research unit – in a stainless steel metal case. A measuring device in the form of a scintillation detector is located in the metal case of the research unit, consisting of: a case, a scintillator (crystal, plastic, liquid), a photoelectric multiplier, a power cell, a source of ionizing low-energy gamma radiation in a special protective case that ensures compliance with sanitary requirements and radiation safety standards, and a cassette for biological tissue to be examined (a sample of biological tissue is placed in the biopsies section of the cassette), which is installed in the cassette holder. The design of the cassette holder includes a knife for cutting excess biopsies. The cassette holder is firmly fixed in the housing of the device's research unit. The control unit houses power elements, a microprocessor controller for processing information and maintaining a database, providing communication with peripheral electronic devices. The front panel of the device houses the information monitor and control points. On the back panel there is a device on/off switch, a fuse and places for connecting additional devices. The device has the possibility of applying protective grounding.
