A single use, self-contained, self-powered disposable oximeter, in the form of a patch or a bandage strip, has mounted thereto a light emitter and a light sensor that together measure at least the SpO2 of the patient. Mounted to an electronics layer of the patch is an application specific integrated circuit (ASIC) that has electronics integrated thereto that controls the operation of the light emitter and light sensor, and the algorithm for calculating from the data collected by the sensor at least the SpO2 of the patient. Optionally, a display and an alarm may also be mounted or embedded onto the patch for respectively displaying at least the SpO2, and for informing the caregiver/patient that at least the SpO2 is not within an acceptable range, if such is the case. Also provided in the patch is a battery that powers the operation of the ASIC circuit and the emitter, as well as the display and alarm if such optional components are provided on the patch. An attachment mechanism is also provided on the patch. Such mechanism may be in the form of an adhesive layer that can removably attach the patch to the patient in either a transmissive mode or a reflective mode. The patch oximeter may also be equipped with a transceiver, and the appropriate electronics, for wirelessly transceiving information to/from a remote device or another wireless patch oximeter. In place of a self-contained power source, the power for operating a wireless patch oximeter may be retrieved from a remote power source, provided that the patch oximeter is within a given distance from such remote power source.본 발명은 패치 또는 붕대 스트립의 형태인 일회용의 자기완비형이고 자기전원형인 옥시미터에 관한 것으로, 이에 환자의 적어도 SpO2를 측정하기 위한 발광체와 광검출기가 배치된다.패치의 전자회로층에는 발광체와 광검출기의 작동을 제어하는 전자회로가 일체로 구성되어 있으며 광검출기에 의하여 수집된 데이터로부터 환자의 SpO2를 계산하기 위한 알고리즘을 갖는 주문형반도체(ASIC)가 배치된다. 선택적으로, 적어도 SpO2를 표시하고 적어도 SpO2가 허용범위내에 있지 않는 경우이를 간병인/환자에게 알리기 위한 디스플레이와 알람이 패치에 배치되거나 매입된다.
