MICROTOME AND METHOD FOR CONTROLLING PROTECTIVE DEVICE OF MICROTOME Russian patent published in 2017 - IPC G01N1/06 B26D7/22 

FIELD: physics.

SUBSTANCE: microtome contains an object-holder knife for the object, a protective device for the knife. The object-holder is movable against the said knife. The protective device is movable between, at least, partly the knife closing protective position and the knife opening position. The protective device is connected to the drive device, by which it is adapted to move, at least, from the knife opening position into its protecting position. The microtome state parameters may be recorded by, at least, one sensor and processed in the control device. The drive device is adapted to control the control device according to, at least, one parameter of the microtome state. The sensor is dapted to register the relative motion between the object-holder and the knife and/or the object-holder position. The method for controlling the microtome protective device is that the microtome state parameters are registered by means of the sensor and processed in the control unit. Moreover it is controlled, whether there occurs a relative movement at the specified period of time between the knife and the object-holder and/or whether the object-holder is located at the predetermined position for the object replacement. The protective device is moved depending on the state parameters by the drive unit in, at least, partially knife closing protective position.

EFFECT: reduction of the user injury.
