Изобретение относитс  к медицине.This invention relates to medicine.

Известные приснособлени  дл  сн ти  гистологических срезов с ножа микротома выполнены в виде ленточного транспортера, лента которого приводитс  ъ движение синхронно с движением препарата или «ожа.The known devices for removing histological sections from the microtome knife are made in the form of a belt conveyor, the tape of which is driven in a movement synchronously with the movement of the preparation or "skin.

С целью устранени  деформации среза в предлагаемом приспособлении установлен вращающийс  полый перфорированный барабан , .который соединен с источником отрицательного давлени , а внутри барабана расположен пневмосбрасыватель, соединенный с источником положительного давлени .In order to eliminate the deformation of the cut, in the proposed device a rotating hollow perforated drum is installed, which is connected to a source of negative pressure, and a pneumatic spreader is located inside the drum, connected to a source of positive pressure.

На чертеже схематически показано предлагаемое приспособление.The drawing schematically shows the proposed device.

Приспособление содержит предметный столик 1, на котором укреплен гистологический блок 2 и режущий пож 3. Вращающийс  барабан 4 представл ет собой полый перфорированный цилиндр, укрепленный относительно режущего ножа так, что его бокова  поверхность расположена параллельно режущей кромки ножа и отстоит от нее На рассто нии, обеспечивающем зазор, больший толщ-ины среза.The fixture contains a stage 1, on which the histological unit 2 and the cutting ax 3. are fixed. The rotating drum 4 is a hollow perforated cylinder, reinforced relative to the cutting knife so that its lateral surface is parallel to the cutting edge of the knife and is separated from it. providing a gap, a larger thickness of the cut.

Под барабаном расположен транспортер 5. Внутри барабана имеетс  пневмосбрасыватель 6, соединенный с источником 7 положительного и отрицательного давлени , оасположенным на части поверхности барабана, наход щейс  над транспортером.A conveyor 5 is located under the drum. Inside the drum there is a pneumatic spreader 6 connected to a source 7 of positive and negative pressure located on the part of the drum surface located above the conveyor.

При движении предметного столика с гистологическим блоком к режущему ножу барабан и транспортер поворачиваютс  с той же Поступательной скоростью, что и предметный столик. Это достигаетс  с помощью жесткого механического согласовани  поворота барабана и неремещени  предметного столика. Срезаемый ножом гистологический срез прилипает к поверхности барабана за счет того,When the stage with the histological unit moves to the cutting knife, the drum and the conveyor rotate at the same Progressive speed as the stage. This is achieved by hard mechanical matching of the rotation of the drum and non-displacement of the stage. The histological slice cut by a knife sticks to the surface of the drum due to the fact

что от источника отрицательного давлени  через регул тор 8 давлени  внутри барабана создаетс  отрицательное давление. При движении среза над транспортером пневмообразователь создает на поверхности этой частиthat a negative pressure is created from the negative pressure source through the pressure regulator 8 inside the drum. When the slice moves over the conveyor, the air former creates on the surface of this part

барабана положительное давление и срез сбрасываетс  на транспортер. После полного срезани  и некоторого холостого хода весь срез оказываетс  сброшенным на транспортер .The drum has a positive pressure and the cut is dropped to the conveyor. After a complete cut and some idling, the whole cut is dropped onto the conveyor.

Предмет изобретени Subject invention

Прис1 особление дл  сн ти  гистологических срезов с ножа микротома, содерл ащее .ленточный транспортер, отличающеес  тем, что, с целью устранени  деформации среза, в нем установлен вращающийс  полый перфорированный барабан, который соединен с источником отрицательного давлени , а внутри барабана расноложеп пневмосбрасыватель , соединенный с источником ноложителыюго давлени An attachment for removing histological sections from a microtome knife, containing a tape conveyor, characterized in that, in order to eliminate deformation of the section, a rotating hollow perforated drum is installed in it, which is connected to a source of negative pressure, and inside the drum, with pressure source
