Transdermal analyte sensing device
First Claim
1. A transdermal analyte sensor device comprising:
- a sensor cartridge comprising;
a membrane permeable to a target analyte transdermally received from a subject,a reservoir containing a fluid to receive the target analyte through the membrane and an enzyme to react with the target analyte to form a byproduct,a working electrode to generate an electrical current based on a concentration of a byproduct, anda cartridge electrical contact disposed on a flange to transmit the electrical current from the working electrode; and
a device body comprising;
a device electrical contact to receive the electrical current from the cartridge electrical contact,a transmitter to transmit a signal based on the electrical current to a monitoring device, anda cartridge receptacle configured to slidably receive the sensor cartridge and position the membrane to contact skin of the subject, wherein when the sensor cartridge is slidably received in the cartridge receptacle, the flange is received in a recess of the cartridge receptacle such that the cartridge electrical contact is electrically coupled to the device electrical contact.
