1. A medical sensor system (10, 10′
- ) for detecting a characteristic (12) of a human and/or animal body, the sensor system (10, 10′
) including;
a. a characteristic carrier receptor (18) configured to bind to a second characteristic carrier (20) of interest for sensing;
b. a first characteristic carrier (16);
(1) different from the second characteristic carrier (20), and(2) configured to bind to the characteristic carrier receptor (18) in competition with the second characteristic carrier (20);
c. a sensor (14) configured to generate a signal dependent on the binding of at least one of the first characteristic carrier (16) and the second characteristic carrier (20) to the characteristic carrier receptor (18);
d. a reservoir (38) wherein the sensor (14) is situated, ande. an organic membrane (36, 36a) closing the reservoir (38), wherein the organic membrane (36, 36a);
(1) always retains the first characteristic carrier (16) within the reservoir (38), and(2) is controllable to selectively allow and deny entry of the second characteristic carrier (20) into the reservoir (38).

Abstract
A medical sensor system (10, 10′) for detecting at least one characteristic (12) of an human and/or animal body has a sensor (14), a first characteristic carrier (16), and a characteristic carrier receptor (18). The first characteristic carrier (16) differs, in terms of at least one characteristic parameter, from a second characteristic carrier (20) which is present at least at the time of detection. The sensor (14) is preferably located in vivo at the time of detection of the at least one characteristic.

18. A medical sensor system for detecting a characteristic of a human and/or animal body, the sensor system including:
-
a. a reservoir; b. a first characteristic carrier within the reservoir; c. a sensor within the reservoir, the sensor being configured to generate a signal dependent on the relative amounts of; (1) the first characteristic carrier adjacent the sensor, and (2) a second characteristic carrier adjacent the sensor, d. a membrane closing the reservoir, the membrane having a pore therein, the pore having a pore size which is controllable to selectively; (1) allow passage of the second characteristic carrier into the reservoir, and (2) prevent passage of the second characteristic carrier into the reservoir. - View Dependent Claims (19)
