Abstract
A vacuum suspension system includes a prosthetic socket adapted to receive a residual limb. A pump system includes a pump mechanism in fluid communication with the prosthetic socket, and at least one sensor associated with the prosthetic socket and/or the pump mechanism. A control system is operably connected to the pump mechanism and the least one sensor. The control system is arranged to receive and process data from the at least one sensor and to actuate the pump mechanism based on the received data from the at least one sensor.
Claims11
A vacuum suspension system comprising:
- a prosthetic socket adapted for receiving a residual limb;
- a pump system including a pump mechanism in fluid communication with the prosthetic socket, and a plurality of sensors associated with at least one of the prosthetic socket and the pump mechanism, the sensors measuring at least volume fluctuation of the residual limb, pressure changes inside the prosthetic socket, and relative movement between the residual limb and the prosthetic socket;
- and
- a control system operably connected to the pump mechanism and the sensors, the control system arranged to receive data from the sensors representative of the pressure changes inside the prosthetic socket, the relative movement between the residual limb and the prosthetic socket, and the volume fluctuation of the residual limb over a period of time, and generate vacuum performance information representative of an effectiveness of the pump mechanism by comparing the pressure change inside the prosthetic socket and relative movement between the residual limb and the prosthetic socket when the volume of the residual limb fluctuates.
