  • DISPOSABLE LIGHT THERAPY HAND PROBES
    Publication number: 20260027381
    Abstract: A handheld therapy device includes a handle having a fiber optic cable and a diffusing light assembly. The handheld therapy device further includes a beam transmission tube attached to the handle. The beam transmission tube is configured to receive diffused light from the diffusing light assembly and allow the diffused light to pass through the beam transmission tube in an axial direction. The handheld therapy device further includes a beam reflective end configured to receive the diffused light passed through the beam transmission tube and to reflect the diffused light in a non-axial direction. The handheld therapy device further includes a transparent tube removably attached to the handle and at least partially enveloping the beam transmission tube. The transparent tube is at least partially transparent to allow the diffused light reflected in the non-axial direction off of the beam reflective end to pass therethrough.
