Abstract: Изобретение относится к медицине и может быть использовано для оценки уровня кровотока у пациентов с диабетом. Для этого проводят флуоресцентную ангиографию в области интереса в конечности пациента. При этом внутривенно вводят раствор индоцианина зеленого в дозе 5 мг/кг. Затем выполняют процедуру ангиографии. При этом для возбуждения флуоресценции раствора индоцианина зеленого используют источник лазерного излучения с длиной волны в диапазоне 780-790 нм. Уровень кровотока оценивают по карте распределения времени наступления максимума интенсивности флуоресценции индоцианина зеленого. На указанной карте распределения желтому цвету соответствует наиболее раннее наступление максимума флуоресценции, при котором делают вывод об оптимальном уровне кровотока. Темно-фиолетовому цвету на указанной карте соответствует наиболее позднее наступление максимума флуоресценции, при котором делают вывод о низком уровне кровотока и риске развития необратимых изменений в конечности. Изобретение позволяет повысить диагностическую эффективность флуоресцентной ангиографии за счет оценки параметров кровотока у пациента. 7 ил., 2 пр.

Abstract: FIELD: cutting tools. 
     SUBSTANCE: group of inventions relates to cutting apparatuses for detachment of structural units interconnected by a mechanical connection. The cutting apparatus (20) comprises at least one breech piece (1), at least one locking element (2), at least one spring (6), at least one striker (7), a percussion cap (9), a charge (13), a cutting element (14), a stop (15) and a shear pin (17). At least one locking element (2) is made in form of a ball and provides a connection between the breech piece (1) and the striker (7). The locking element (2) is configured to unlock to detach the breech piece (1) from the striker (7) during use. The spring (6) is tightened. After the breech piece (1) has passed the preset path, the locking element (2) is unlocked. The unlocking leads to the unloading of the spring (6) resulting in the striker (7) accelerating and in the end striking the percussion cap (9). As a result of the strike of the striker (7) on the percussion cap (9), the pyrotechnic charge contained therein is ignited. Due to initiation of the pyrotechnic charge in the percussion cat, a retarder (11) ignites, if present. The retarder therein adjusts the delay time. The next charge is then ignited (13). The resulting volume of gas puts a pressure on the cutting element (14). Upon reaching a certain pressure, the shear pin (17) is cut off resulting in the cutting element (14) accelerating in the axial direction. The cutting element (14) strikes at a high speed resulting from the acceleration on the stop (15) and thereby penetrates the stop. The connection subject to cutting passed through the hole in front of the stop is therein detached. 
     EFFECT: invention allows to ensure reliable detachment of at least two structural groups.

Abstract: Изобретение относится к стоматологии и может быть использовано для изоляции межзубного пространства и слизистой ротовой полости в адгезивных технологиях, эндодонтических операциях и при отбеливании зубов. Измеряют длину участка десны с отбеливаемыми зубами. Из одностороннего самоклеящегося материала вырезают полоску защитной пленки шириной от 5 до 10 мм и длиной, равной измеренному участку десны. Полоску прижимают гидрофильной стороной к вестибулярной поверхности слизистой вдоль отбеливаемых зубов и приклеивают. Убедившись в правильном расположении полоски, врач приступает к изготовлению защитного барьера из жидкой слепочной смеси, содержащей как минимум один корригируемый компонент на основе силикона и активатор. Жидкую слепочную смесь до однородности смешивают из корригируемого компонента, активатора и лечебно-профилактического геля, состоящего из гиалуроната натрия, трилона-Б, клуцела, дистилированной воды и хлорбензилового спирта.
