    摘要： A neuro-muscular electrical stimulation system provides a series of electrical pulses to instigate muscle twitch to aid in preventing the occurrence of deep vein thrombosis. The duration and duty cycle of the electrical pulses provided to a patient's muscle tissue is controlled to instigate muscle twitch without causing tetanic muscle contractions. The system preferably includes a single electrode that is placed upon each calve of a patient. The electrical stimulator device includes a unique housing and circuit board arrangement that facilitates easy assembly without requiring any soldering connections between the circuit board, a power source and electrical leads that are utilized to provide signals to the electrodes that are placed on the patient. The circuit board preferably is made from a slightly resilient plastic material that is flexed from a disconnected position into an electrically connected position upon assembly of the stimulator device.

    摘要： A powered medical instrument includes a manually operable foot switch coupled to a motor control unit which in turn is coupled to an autoclavable handpiece containing a brushless sensorless electric motor driving a tool. The motor control arrangement includes a control panel through which a user can select a maximum torque value for the motor, and includes a torque limit circuit which limits the motor torque to the torque limit value selected by the user. The control panel also provides a digital display of actual motor speed and allows the user to digitally specify a maximum motor speed. The output of the foot switch is adjusted by a transfer function and then used to control motor speed, and the transfer function is adjusted as necessary to precisely conform the actual motor speed and thus the displayed speed to the selected maximum speed. The feedback path for the actual motor speed is entirely digital, so that a highly accurate value of actual speed is available for display and for adjustment of the transfer function.
