- An example of the present subject matter includes an inexpensive wireless apparatus that can be fitted to a patient and discarded after use. The apparatus can include a wireless communication module that allows communication with a remote device. The remote device can include a monitor, a display, a storage device, or other module. The apparatus can include an oximeter measuring device having a sensor module that generates data corresponding to pulse oximetry or regional oximetry. The apparatus includes a flexible structure that can be conformed to provide a close fit on a patient and wirelessly provide medical data to a remote device. After collecting oximeter data or other data while fitted to a patient, the apparatus can be discarded.
- One example of the apparatus includes an oximeter module having hardware and software, a sensing element, a power management unit, a power supply, a power control module, and a communication module.
- The sensing element can include one or more optical emitters and one or more optical detectors. The optical emitters and optical detectors are held in position by a carrier structure at a spacing that provides light energy to the tissue with a specific alignment. The light can be transmitted through the tissue or directed to reflect from the tissue. For example, one embodiment includes light directed to pass from a first side of the tissue to a second side of a tissue. Modulation of the detected light by traversing the optical path can provide oximetry data.
