Live display appartus for setting extenson and flexion limits in continuous passive motion (CPM) system
First Claim
1. A live display apparatus for selectively setting limits of movement in a continuous passive motion (CPM) system, including:
- CPM carriage means for supporting a patient'"'"'s limb through a range of reciprocal angular movement;
drive means for driving the carriage means through the range of reciprocal angular movement;
carriage state sensor means for providing a signal representative of a state of the carriage means within the range of reciprocal angular movement;
first limit memory means for storing data;
first limit select switch means having OFF and first ON positions; and
control means coupled to the carriage state sensor means, first limit memory means and the first limit select switch means, for controlling the drive means, wherein the control means causes the carriage means to be operated in a first limit select mode and driven through its range of movement in a first direction to a first selected limit of movement while the first limit select switch means is in its first ON position, causes data representative of the state of the carriage at the first selected limit of movement to be stored in the first limit memory means when the first limit select switch means is switched from the first ON position to the OFF position, and causes the carriage means to be operated in a normal operating mode and driven as a function of the signal provided by the carriage state sensor means and the data stored in the first limit memory means when the first limit select switch means is in its OFF position.

Abstract
A live display apparatus for setting extension and flexion limits in a continuous passive motion (CPM) system. The CPM system includes a carriage for supporting a patient'"'"'s limb through a range of reciprocal angular movement, a drive motor for driving the carriage, a carriage state sensor for providing a signal representative of carriage state and a control unit responsive to the carriage state sensor for controlling the drive motor. The live display apparatus includes an operator controlled extension limit select switch which is operatively coupled to the control unit. The select switch causes the carriage to be driven through its range of movement to a desired extension limit when actuated during an extension limit select mode. Data representative of the selected extension limit is stored in extension memory. An extension limit display is responsive to the control unit and provides a visual display indicative of the extension limit selected. An operator controlled flexion limit select switch is operatively coupled to the control unit, and causes the carriage to be driven through its range of movement to a desired flexion limit when actuated during a flexion limit select mode. Data representative of the selected flexion limit is stored in flexion memory. A flexion limit display provides a visual display indicative of the selected flexion limit.
