Abstract

Diagnostic devices can be used for diagnosing lymphedema. The diagnostic devices may include an array of sensors, which can at least include a durometer, temperature sensor, and dielectric sensor, to measure parameters of tissue. The measurements may be used to generate a tissue health score to diagnose lymphedema and monitor tissue heath.

Claims (13)

1 . A diagnostic device for measuring a hardness and a bioimpedance of a tissue, the diagnostic device comprising:

a bioimpedance sensor, the bioimpedance sensor comprising a conductive probe, wherein the bioimpedance sensor is configured to measure the bioimpedance of the tissue;

an electrical ground surrounding at least a portion of the conductive probe, wherein the conductive probe is stationary with respect to the diagnostic device; and

a durometer sensor, the durometer sensor comprising a durometer probe disposed radially inward of the conductive probe and extending past a tip of the conductive probe, the durometer probe moveable with respect to the conductive probe, wherein the durometer sensor is configured to measure the hardness of the tissue.

2 . The diagnostic device of claim 1 , wherein the bioimpedance and hardness measurements are used to generate a tissue health score for the tissue.

3 . The diagnostic device of claim 1 , further comprising a temperature sensor configured to measure a temperature of the tissue.

4 . The diagnostic device of claim 3 , wherein the bioimpedance, hardness, and temperature measurements are used to generate a tissue health score for the tissue.

5 . The diagnostic device of claim 1 , further comprising an insulator disposed between the conductive probe and the electrical ground.

6 . The diagnostic device of claim 5 , wherein the insulator is offset from a leading edge of the electrical ground such that an air gap is disposed between the conductive probe and the electrical ground.

7 . The diagnostic device of claim 1 , further comprising a force transducer body, a force transducer tip, and a spring disposed between the force transducer body and the force transducer tip, and wherein the durometer probe is configured to be pushed by the tissue to translate the force transducer tip toward the force transducer body to measure the hardness of the tissue.

8 . The diagnostic device of claim 1 , wherein the diagnostic device is configured to measure the hardness of the tissue and the bioimpedance of the tissue simultaneously.

9 . The diagnostic device of claim 1 , wherein the diagnostic device prompts a user to take measurements at a location on a body of the user.

10 . The diagnostic device of claim 1 , wherein a computing device in communication with the diagnostic device prompts a user to take measurements at a location on a body of the user.
