Definitions
- the present invention relates to an apparatus for monitoring the environment of
- a prosthetic socket and in particular to an apparatus for monitoring various parameters
- the prosthetic limb when one of these parameters exceeds a pre-set range.
- both stance and swing phases using the vacuum-assisted socket reduce the fluid forced out and increase the amount of fluid drawn into the limb, thereby preventing volume loss. Ibid.
- Ambulation causes the shape of the residual limb, the temperature within the prosthetic socket, and pressures within the socket to change. There is a need for a
- the apparatus can include at least one of a
- apparatus can include at least one sensor for sensing at least one of pressure, force,
- the at least one sensor can be configured with
- the apparatus can also include an alarm when a value sensed by the at least one sensor is beyond a value limit.
- This method can include sensing at least one of pressure, force, temperature, and moisture with respect to at least one the socket, the artificial limb, and a space
- It can also include setting sensor value limits, and indicating when a sensed value is beyond at least one of the sensor value limits.
- Fig. 1 is a graph showing sensor calibration.
- Fig. 2 is a graph showing sensor calibration.
- Fig. 3 is a schematic side elevational view of an artificial limb with a
- Fig. 4 is a schematic elevational view of a readout device for displaying various
- the present invention may be used to measure the following pressures: negative pressure between the socket and the liner; negative pressure between the liner and the
- Cloth tape was placed on the back of the sensor tail to create an air wick from the sensor vent hole to the tubing that contains the wires at the solder tabs.
- curvilinear output of the sensors means that the precision decreases as the pressure
- the amputee first donned a urethane liner with a nylon sheath
- the flexible sensors had a
- the sensor placement avoided bony prominences and areas of soft tissue were targeted.
- the most proximal sensor was placed on the gastrocnemius below the posterior trim lines of the socket.
- proximal and distal sensors formed a pentagon on the posterior side of the residual limb.
- a sixth sensor capable of documenting negative air pressures using a full bridge
- the force sensing resistors were part of a voltage dividing circuit
- the senor was powered with 5 vdc and an
- the air pressure sensor was excited with 10 vdc and run through an
- Vaseline was placed around the flat wire as it exited the liner to minimize the
- a subject's walking velocity was controlled at 4 km/hr by having the subject follow a
- the pressure curves are generally double-peaked during the stance phase and single peaked during the swing phase of ambulation. Peak pressures in stance and swing phases were obtained using a 0.1 second averaging period. Average pressures during stance and swing phase were found using heelstrike and toe-off as the indicators of the beginning and end of the phases. An impulse value was also obtained for stance
- Temperature may be measured by appropriate sensors embedded in the socket
- Moisture may be measured by an instrument such as a hygrometer.
- the fitter proceeds to set limits (e.g., upper and lower) for the display or alarm, e.g., audible alarm.
- the display and alarm device preferably uses a digital readout and/or an audible alarm. A schematic of such a device is shown in Fig. 2.
- the limits may be set at the device itself or by means of a computer.
- computer may be connected to the device by a cable or other means such as an infrared signal.
- the patient would then walk for several minutes to establish a baseline and the fitter would then set upper and lower limits based on the information gained. Once the limits are set, the computer can be disconnected and the device would
- the device would monitor temperature (preferably in a range (i.e., within the
- moisture preferably in a range from
