Abstract: An oximetry device includes an inductive detector. When the oximetry device is sealed in a sheath and a latch of the sheath is in a latched position, the inductive detector inductively detects that latch. The oximeter device uses first information received from the detector for the latch being in the latched position to allow the device to take oximetry measurements. The oximeter device uses second information received from the detector for the latch not being in the latched position to allow the device to display a message on a display of the device that the sheath is not sealed. The displayed message indicates to a user that the sheath lid needs to be closed. The closed lid prevents contaminants in the sheath from reaching patient tissue during use of the device and sheath.
