No
The description focuses on basic signal processing, data display, storage, and transmission, with no mention of AI, ML, or advanced analytical techniques.
No
The device is described as an external pulse oximeter designed for "spot checking of the pulse oxygen saturation and pulse rate." Its functions are to measure, display, and record these physiological parameters, without any indication of delivering therapy or treatment.
No
Explanation: The device is designed for monitoring pulse oxygen saturation and pulse rate, which are physiological measurements. While these measurements can be used by a healthcare professional to inform a diagnosis, the device itself gathers data and displays it rather than interpreting the data or making a diagnosis.
No
The device description clearly states that the device includes hardware components such as an SpO2 probe, SpO2 module, and either a 30-pin port or a USB plug, in addition to the software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
- Device Function: The MD50i and MD50p external pulse oximeters measure pulse oxygen saturation (SpO2) and pulse rate (PR) directly from the patient's finger using a probe. This is a non-invasive measurement taken in vivo (within the living body), not in vitro (in glass, i.e., outside the body).
- Intended Use: The intended use is for "spot checking of the pulse oxygen saturation and pulse rate for adult at hospital." This aligns with the function of a pulse oximeter, which measures physiological parameters directly from the patient.
- Device Description: The description details the components involved in collecting and processing signals from the patient's finger, not from a biological specimen.
Therefore, the MD50i and MD50p external pulse oximeters are considered medical devices, but they do not fit the definition of an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The external pulse oximeter (MD50i and MD50p) is designed for spot checking of the pulse oxygen saturation and pulse rate for adult at hospital. This medical device can be reused. Not for continuous monitoring.
