1. Apparatus for sensing skin contact probe dislodgement, comprising:
- (a) housing means defining a skin contact surface for said probe;
(b) photoreceptive means located on said skin contact surface of said housing means;
(c) alarm means energized by reception by said photoreceptive means of light, said light having an intensity exceeding a predetermined level, said alarm means being placed a distance away from said housing means; and
(d) photo transmitting means extending out from said housing means for connecting said photoreceptive means and said distant light receptive alarm means.

Abstract
A probe having a contact surface adapted to be placed on a body surface to monitor or control a body function. When the probe is dislodged from the body, an increased radiation level impinging on the contact surface is sensed and an indication of probe dislodgement is provided.

6. Apparatus for sensing probe dislodgement comprising:
-
a probe housing having a contact surface adapted for contact with a body and also having means for carrying a probe; transducer means having a radiation receiving portion located in said contact surface for (1) sensing an increased radiation level impinging upon said contact surface when said probe housing is dislodged from said body and said contact surface is exposed to said increased radiation level, and (2) developing a radiation signal representative of the radiation level impinging upon said contact surface;
means for supplying a threshold signal representative of a predetermined radiation level less than said increased radiation level impinging upon said contact surface when said probe housing is dislodged from said body; andalarm means responsive to said radiation signal and said threshold signal for developing an indication when said radiation level impinging upon said contact surface exceeds said predetermined radiation level. - View Dependent Claims (7, 8, 9, 10, 11)

15. Apparatus for indicating the dislodgement of an article from a body surface, said apparatus comprising:
-
an article having a contact surface adapted for contact with a body surface and a second surface removed from said contact surface; first transducer means having a radiation receiving portion located in said contact surface for (1) sensing an increased radiation level impinging upon said contact surface when said article is dislodged from said body surface and said contact surface is exposed to said increased radiation level, and (2) developing a first radiation signal representative of the radiation level impinging upon said contact surface; second transducer means having a radiation receiving portion located in said second surface for (1) sensing a decreased radiation level impinging upon said second surface when said article is covered and said second surface is exposed to said decreased radiation level, and (2) developing a second radiation signal representative of the radiation level impinging upon said second surface; means for supplying a first threshold signal representative of a first predetermined radiation level less than said increased radiation level impinging upon said contact surface when said article is dislodged from said body; means for supplying a second threshold signal representative of a second predetermined radiation level greater than said decreased radiation level impinging upon said second surface when said article is covered; and alarm means responsive to said first and second radiation signals and said first and second threshold signals for developing an indication where said radiation level impinging upon said contact surface exceeds said predetermined first radiation level or said radiation level impinging upon said second surface falls below said predetermined second radiation level. - View Dependent Claims (16, 17, 18, 19, 20)
