Abstract

Pressure sensitive devices, systems and methods for alerting a user of movements potentially adverse to health or surgical recovery are disclosed. The pressure sensitive device may include a force sensor placed along the anterior aspect of a hand; and a vibration motor in communication with the force sensor in close proximity to the user, e.g., along the posterior aspect of the wrist. The vibration motor is configured to vibrate upon the measured force exceeding a predetermined threshold. This threshold can be adjusted according to clinical application and/or user need. The pressure sensitive device may further include a memory chip or wireless transmitter for recording and relaying data associated with a patient profile, and is enabled to interface with a Wi-Fi sensing technology. Logged data may be used for patient rehabilitation.

Claims

6. The pressure sensitive device of claim 1, wherein the control circuit is changeably programmable for input of the predefined threshold.

7. The pressure sensitive device of claim 1, further comprising a memory device coupled with the control circuit for recording pressure values.

8. The pressure sensitive device of claim 1, further comprising a wireless module for wirelessly transmitting and receiving data.

9. The pressure sensitive device of claim 8, wherein the wireless module includes Bluetooth technology.

10. The pressure sensitive device of claim 1, wherein the indicator component includes a vibration motor.

11. The pressure sensitive device of claim 1, wherein the alert includes at least one of an audible alert, a visual alert or a tactile alert.

12. The pressure sensitive device of claim 1, further comprising an accelerometer configured to activate the indicator component upon exceeding a second predefined threshold.

13. The pressure sensitive device of claim 1 wherein the wearable housing includes a self-adhesive material.

14. A pressure sensitive device for detecting movement adverse to surgical recovery, comprising:

a wearable housing including a hand portion having a plurality of compartments adapted to receive at least one finger of a human hand, and a wrist portion having a proximate end and a distal end, the proximate end defining an opening and the distal end forming a continuous part of the hand portion;

a sensor positioned along the anterior aspect of the wrist portion; and

an indicator component electronically coupled with the sensor,

wherein the indicator component generates an alert when the pressure value exceeds a predefined threshold.
