Abstract

A movement system for use with an overhead patient lift system includes a motor. A drum is operatively coupled to the motor. The drum is configured to be selectively driven by the motor to rotate in one of a clockwise direction and a counter-clockwise direction. A lifting strap is coupled to the drum. The lifting strap is extendable and retractable with respect to a carriage of the overhead patient lifting system as the drum rotates. A manual release operatively coupled to the drum is actuatable to selectively disengage the drum from the motor to allow the lifting strap to be manually extended. Also disclosed is an overhead patient lift system including the movement system and a method for manually extending a lifting strap of an overhead patient lift system.

First claim

What is claimed is:

1. A method of monitoring operation of one or more components of an overhead patient lift system, said method comprising:
transmitting electronic data signals, corresponding to the operation of a component of the overhead patient lift system, to a computer in communication with the overhead patient lift system;
receiving the electronic data signals corresponding to operation of the component of the overhead patient lift system in a processor of the computer;
processing the electronic signals by the processor of the computer to generate electronic operation data of the component of the overhead patient lift system;
determining whether maintenance is advised based on the electronic operation data;
storing the processed electronic operation data of the component of the overhead patient lift system in a non-transient computer readable storage medium in communication with the computer;
displaying the electronic operation data of the component of the overhead patient lift system on a display device in communication with one or more of the computer and the storage medium; and
automatically displaying a visual alert on the display device when, based on the electronic operation data, it is determined that maintenance is advised, upon wake-up of the display device.

2. The method of claim 1 , wherein the component of the overhead patient lift system is one or more of a lift motor, a motor system, a movement system, and a brake system.

3. The method of claim 1 , wherein the transmitting is performed by one or more sensors operatively connected to the component of the overhead patient lift system.

4. The method of claim 1 , wherein the electronic operation data generated by the processor includes at least one of lift operation detection data, lift motor usage data, a total usage data of the overhead patient lift system, a cumulative number of lifts made by the overhead patient lift system, a cumulative number of lifts made by the overhead patient lift system that were over a predetermined threshold weight, a cumulative number of lifts made over a specified period of time, lift motor overload occurrence information, service information, and electric power consumption information.

5. The method of claim 1 , wherein displaying the electronic operation data of the component of the overhead patient lift system on a display device includes displaying pictographic indicators that are representative of the electronic operation data generated by the processor and provide a visual alert regarding the operation of the overhead patient lift system.

6. The method of claim 1 , wherein the display device is one of a display device of the overhead patient lift system and a display device of a remote computer connected to the overhead patient lift system by a computer network.

7. The method of claim 1 , wherein the display device of one of a lift unit or a controller of the lift unit of the overhead patient lift system.
