Method for operating an orthopedic device and corresponding orthopedic device
The invention relates to a method for operating an orthopedic device which supports or replaces a first body part of a wearer and has at least one controllable actuator, wherein the method includes a) determining a chronological profile of at least one parameter, which allows for a conclusion to be made regarding a movement status of the wearer, from measurement values of at least one sensor; b) detecting the movement status from the at least one determined chronological profile; and c) controlling the at least one controllable actuator depending on the identified movement status, wherein at least the chronological profile of at least one parameter of a second body part of the wearer is also used to identify the movement status.
1 . A method for operating an orthopedic device which
supports or replaces a first body part of a wearer, and
comprises at least one controllable actuator,
wherein the method comprises:
a) determining a chronological profile of at least one parameter, which allows for a conclusion to be drawn about a movement status of the wearer, from measurement values of at least one sensor,
b) detecting the movement status of the wearer from the at least one determined chronological profile, and
c) controlling the at least one controllable actuator depending on the detected movement status of the wearer,
wherein at least the chronological profile of at least one parameter of a second body part of the wearer is also used to detect the movement status of the wearer.
2 . The method according to claim 1 , wherein the second body part does not directly abut the first body part.
3 . The method according to claim 1 , wherein the at least one parameter is a relative position, relative movement, relative speed, relative acceleration and/or relative angle of the second body part to the first body part and/or of a first part of the second body part to a second part of the second body part.
4 . The method according to claim 1 , wherein the at least one sensor is configured to detect an absolute angle, a relative angle, a speed, an acceleration, a force, a pressure, a pressure wave, a moment, an electrical field and/or a magnetic field.
5 . The method according to claim 1 , wherein the first body part is an ipsilateral limb or a part thereof, particularly a foot, an ankle and/or a knee, and the second body part is another limb, preferably a contralateral limb or a part thereof, preferably a foot, an ankle and/or a knee.
6 . The method according to claim 1 , wherein the at least one sensor is arranged on a component of the orthopedic device or on the first body part and at least also detects measurement values from which the at least one parameter of the second body part is determined.
7 . The method according to claim 1 , wherein the at least one sensor comprises at least one transmission device and at least one reception device, wherein the transmission device emits measuring radiation, preferably ultrasonic waves and/or electromagnetic measuring radiation, especially preferably radar radiation and/or visible light and/or infrared radiation, and the reception device is configured to receive measuring radiation.
8 . The method according to claim 7 , wherein the reception device receives measuring radiation reflected or re-emitted by the second body part, and the measurement values and the at least one parameter are determined from a transit time, a phase shift, a frequency shift and/or interference with the emitted measuring radiation.
9 . The method according to claim 8 , wherein at least one transponder and/or a tag and/or a reflector for the emitted measuring radiation is arranged on the second body part.
10 . The method according to claim 1 , wherein data of the orthopedic device and/or the wearer is used to determine the at least one parameter, especially to determine the at least one parameter of the second body part.
11 . The method according to claim 1 , wherein at least one control variable of the at least one controllable actuator is controlled to a set point or a set point profile, which is dependent on the detected movement status and the at least one parameter of the functional body part, preferably the contralateral limb.
12 . An orthopedic device for supporting a first body part of a wearer, the orthopedic device comprising:
at least one sensor; and
an electric control unit configured to:
determine a chronological profile of at least one parameter, which allows for a conclusion to be drawn about a movement status of the wearer from measurement values from the at least one sensor;
detect the movement status of the wearer from the at least one determined chronological profile; and
control the at least one controllable actuator depending on the detected movement status of the wearer; wherein
at least the chronological profile of at least one parameter of a second body part of the wearer is also used to detect the movement status of the wearer.
13 . The orthopedic device of claim 12 , wherein the second body part does not directly abut the first body part.
14 . The orthopedic device of claim 12 , wherein the at least one parameter is a relative position, relative movement, relative speed, relative acceleration and/or relative angle of the second body part to the first body part and/or of a first part of the second body part to a second part of the second body part.
15 . The orthopedic device of claim 12 , wherein the at least one sensor is configured to detect an absolute angle, a relative angle, a speed, an acceleration, a force, a pressure, a pressure wave, a moment, an electrical field and/or a magnetic field.
16 . The orthopedic device of claim 12 , wherein the first body part is an ipsilateral limb or a part thereof, particularly a foot, an ankle and/or a knee, and the second body part is another limb, preferably a contralateral limb or a part thereof, preferably a foot, an ankle and/or a knee.
17 . The orthopedic device of claim 12 , wherein the at least one sensor is arranged on a component of the orthopedic device or on the first body part and at least also detects measurement values from which the at least one parameter of the second body part is determined.
18 . The orthopedic device of claim 12 , wherein the at least one sensor comprises at least one transmission device and at least one reception device, wherein the transmission device emits measuring radiation, preferably ultrasonic waves and/or electromagnetic measuring radiation, especially preferably radar radiation and/or visible light and/or infrared radiation, and the reception device is configured to receive measuring radiation.
19 . The orthopedic device of claim 18 , wherein the reception device receives measuring radiation reflected or re-emitted by the second body part, and the measurement values and the at least one parameter are determined from a transit time, a phase shift, a frequency shift and/or interference with the emitted measuring radiation.
20 . A method for operating an orthopedic device which supports or replaces a first body part of a wearer, and comprises at least one controllable actuator, wherein the method comprises:
a) determining at least one chronological profile of at least one parameter, allowing for a conclusion to be drawn about a movement status of the wearer from measurement values of at least one sensor;
b) detecting the movement status of the wearer from the at least one determined chronological profile; and
c) controlling the at least one controllable actuator depending on the detected movement status of the wearer;
wherein at least the chronological profile of at least one parameter of a second body part of the wearer is also used to detect the movement status of the wearer, the second body part not directly abutting the first body part; and
