Abstract
Изобретение относитс к криогенному медицинскому оборудованию, в котором биологическа ткань разрушаетс за счет охлаждени путем подвода к ней криогенной жидкости через теплоизолированный зонд. Цель изобретени - повышение безопасности в эксплуатации и ускорение процесса замораживани . Криохирургический инструмент содержит теплообменник - ожижитель 1, который размещен внутри емкости 2 дл криоагента. Газ-хладоноситель поступает в теплообменник-ожижитель 1 через фильтр-вымораживатель 3 дл удалени высококип щих примесей. Предусмотрено два варианта подачи хладоносител в теплообменник: под избыточным давлением до штуцера 4 и под действием разрежени , создаваемого за штуцером отвода паров хладоносител . Криоагент жидкий, (азот) кипит в емкости 2 под атмосферным давлением, а в линии подачи хладоносител давление может быть повышено до 3,0 МПа, что позвол ет использовать дл подачи хладоносител трубы малого диаметра (0,2-0,8 мм). 3 ил.The invention relates to cryogenic medical equipment, in which biological tissue is destroyed due to cooling by supplying a cryogenic liquid to it through a heat-insulated probe. The purpose of the invention is to increase operational safety and speed up the freezing process. The cryosurgical instrument contains a heat exchanger - liquefier 1, which is placed inside the tank 2 for the cryoagent. The coolant gas enters the liquefaction heat exchanger 1 through filter-freezer 3 to remove high-boiling impurities. There are two options for supplying the coolant to the heat exchanger: under pressure to fitting 4 and under the action of a vacuum created behind the fitting of the coolant vapor. The liquid cryogenic agent (nitrogen) boils in the tank 2 at atmospheric pressure, and the pressure in the coolant supply line can be increased to 3.0 MPa, which allows the use of small diameter pipes (0.2-0.8 mm) for supplying the coolant. 3 il.
