Abstract
A system for applying external compression to a limb of a user via a system of actuated barrels with compression elements. The system may include a motor, a brake configured to selectively restrict the rotation of different barrels, and a controller configured to operate the brake and motor at different periods of time during use. Sensors may be included, which are coupled to a controller, which, based on sensor data, dictates the timing and degree of compression by controlling the braking system and applied motor current.
Claims24
A system, comprising:
- an actuation module having a motor, a motor barrel couple to the motor and is rotatable about a longitudinal axis, a secondary barrel that is rotatable about the longitudinal axis, and a brake coupled to the motor barrel and the secondary barrel;
- a first compression element coupled to the motor barrel and configured to apply compression to a limb when placed around the limb when the motor barrel is rotating;
- a second compression element coupled to the secondary barrel and configured to apply compression to a limb when placed around the limb when the second barrel is rotating;
- and
- a controller operably coupled to the motor and the brake, the controller configured to, in response to one or more inputs, in a first operating condition, cause the motor to rotate the motor barrel and the secondary barrel, and in a second operating condition, cause the brake to inhibit rotation of the secondary barrel while permitting the motor barrel to rotate independently of the secondary barrel.
A system, comprising:
- a) an actuation module having:
- a motor;
- a shaft that extends along a longitudinal axis and is coupled to the motor, the shaft configured to rotate about the longitudinal axis in response to operation of the motor;
- a motor barrel coupled to the shaft such that the motor barrel is rotatable about the longitudinal axis;
- a secondary barrel coupled to the shaft such that the secondary barrel is rotatable about the longitudinal axis;
- a brake coupled to the motor barrel and the secondary barrel;
- b) a first compression element coupled to the motor barrel and configured to apply compression to a limb when placed around the limb;
- c) a second compression element coupled to the secondary barrel and configured to apply compression to a limb when placed around the limb;
- and
- d) a controller operably coupled to the motor and the brake, the controller configured to, in response to one or more inputs, in a first operating condition, cause the motor to rotate the motor barrel and the secondary barrel, and in a second operating condition, cause the brake to inhibit rotation of the secondary barrel while permitting the motor barrel to rotate independently of the secondary barrel.
A system, comprising:
- an actuation module;
- a first compression element coupled to the actuation module and configured to apply compression to a limb when placed around the limb;
- a second compression element coupled to the actuation module and configured to apply compression to the limb when placed around the limb;
- at least one sensor configured to measure pressure applied by the first and second compression elements to the limb;
- and
- a controller operably coupled to the at least one sensor and the actuation module, the controller configured to, in response to data obtained by the at least one sensor, automatically cause the first and second compression elements to apply compression to the limb up to a predetermined threshold of pressure.
