Abstract

A wearable health management system includes a flexible member configured to be worn on an affected area by a patient. At least one actuator is operably coupled to the flexible member. The at least one actuator is configured to be adjusted between a deployed state and a non-deployed state. At least one of a photoplethysmogram sensor and a bioimpedance sensor is coupled to the flexible member to obtain one or more health metrics from the patient. A controller is in communication with the at least one actuator. The controller is configured to adjust the at least one actuator to the deployed state to provide a selected pressure to the affected area.

First claim

What is claimed is:

1. A wearable health management system, comprising:
a flexible member configured to be worn on an affected area by a patient;
at least one actuator operably coupled to the flexible member, the at least one actuator configured to be adjusted between a deployed state and a non-deployed state;
a vacuum pump, wherein the at least one actuator is a soft robotics assembly and includes a plurality of segments disposed adjacent to one another within a cavity defined by a membrane, and wherein the vacuum pump is configured to remove fluid from the cavity, and consequently, adjust the at least one actuator to the deployed state,
wherein the plurality of segments are disposed in a linear configuration within the membrane, and
wherein the soft robotics assembly is configured to bend to the deployed state;
at least one of a photoplethysmogram sensor and a bioimpedance sensor coupled to the flexible member to obtain one or more health metrics from the patient; and
a controller in communication with the at least one actuator, wherein the controller is configured to adjust the at least one actuator to the deployed state to provide a selected pressure to the affected area.

2. The wearable health management system of claim 1 , wherein the at least one actuator includes a plurality of actuators arranged along the flexible member, and wherein the controller is configured to adjust the plurality of actuators to provide the selected pressure in a directional pattern.

3. The wearable health management system of claim 1 , wherein the controller is configured to communicate with a remote device to receive an input to control the at least one actuator.

4. The wearable health management system of claim 1 , wherein each of the photoplethysmogram sensor and the bioimpedance sensor is coupled to the flexible member, and wherein the photoplethysmogram sensor includes an emitter having a first light source configured to emit visible light and a second light source configured to emit infrared light and a detector configured to receive the visible light and the infrared light of the emitter, and further wherein the bioimpedance sensor includes drive electrodes and sense electrodes.

5. The wearable health management system of claim 1 , wherein the at least one actuator includes multiple actuators configured as soft robotics assemblies, and wherein the controller is configured to independently activate each soft robotics assembly to provide pressure in a directional pattern.

6. The wearable health management system of claim 1 , wherein a space is defined between side surfaces of adjacent segments of the plurality of segments, and wherein the side surfaces are in an abutting relationship with one another when the at least one actuator is in the deployed state.

7. The wearable health management system of claim 1 , wherein the membrane is configured to contract around the plurality of segments to cause the at least one actuator to bend at joints between adjacent segments of the plurality of segments in response to the vacuum pump removing the fluid from the cavity.

8. The wearable health management system of claim 1 , wherein the fluid is directed into the cavity of the membrane to adjust the at least one actuator to the non-deployed state.

9. The wearable health management system of claim 1 , wherein fluid communication between the vacuum pump and the cavity is disrupted to adjust the at least one actuator to the non-deployed state.

10. The wearable health management system of claim 5 , wherein the flexible member includes pockets for receiving the soft robotics assemblies.

11. A garment for providing treatment, comprising:
a first layer;
a second layer coupled to the first layer, wherein the first layer and the second layer are configured to be worn over an affected area;
an actuator disposed between the first layer and the second layer, wherein the actuator is operable between a deployed state and a non-deployed state, and wherein the actuator is a soft robotics assembly including:
a membrane defining a cavity;
segments disposed within the cavity; and
a vacuum pump in fluid communication with the cavity via a vacuum port, wherein the vacuum pump is configured to vacuum fluid from the cavity and, consequently, contract the membrane around the segments and adjust the segments to the deployed state,
wherein the segments are disposed in a linear configuration within the membrane, and wherein the soft robotics assembly is configured to bend to the deployed state; and

a controller communicatively coupled to the actuator and configured to adjust the actuator between the deployed state and the non-deployed state.

12. The garment of claim 11 , further comprising:
a photoplethysmogram sensor coupled to at least one of the first layer and the second layer to obtain photoplethysmogram data; and
a bioimpedance sensor coupled to at least one of the first layer and the second layer to obtain impedance data.

13. The garment of claim 11 , wherein each segment has an outer surface, an inner surface, and angled side surfaces extending between the outer surface and the inner surface, and wherein a length of the outer surface is greater than a length of the inner surface, and further wherein a joint is defined at each interface between adjacent segments, each joint defining a space between the angled side surfaces of the adjacent segments.

14. The garment of claim 13 , wherein the space between the angled side surface of one of the segments and the angled side surface of an adjacent one of the segments is smaller when the soft robotics assembly is in the deployed state.

15. The garment of claim 13 , wherein the angled side surface of one of the segments abuts the angled side surface of an adjacent one of segments when the soft robotics assembly is in the deployed state.

16. The garment of claim 11 , further comprising:
a bioimpedance sensor coupled to at least one of the first layer and the second layer, wherein the bioimpedance sensor includes a drive sensor for applying an electric current and a sense electrode.

17. The garment of claim 11 , further comprising:
a photoplethysmogram sensor coupled to at least one of the first layer and the second layer to obtain photoplethysmogram data.

18. The garment of claim 17 , wherein the photoplethysmogram sensor includes an emitter having a first light source configured to emit visible light and a second light source configured to emit infrared light and a detector configured to receive the visible light and the infrared light of the emitter.

19. The garment of claim 11 , wherein the segments are constructed of silicone.
