Indications for Use

The Fingertip Pulse Oximeter MD300CL37 is a portable, non-invasive device intended for spot checking of oxygen saturation of arterial hemoglobin (SpO2) and pulse rate of adult, adolescent, child and infant patients in hospitals, hospital-type facilities, and home environments.

Device Story

Battery-powered fingertip pulse oximeter; detects and displays SpO2 and pulse rate. Uses dual-wavelength LED (660nm red, 940nm infrared) and photodetector to measure light absorption in pulsating arteriolar vascular bed. Device automatically powers on when finger is inserted; powers off after 8 seconds of no signal. Used by clinicians or patients for spot-checking in hospitals, clinics, or home. Output displayed on OLED screen. Provides non-invasive physiological monitoring to assist in assessing oxygenation status.

Clinical Evidence

Prospective clinical study with 12 healthy adult volunteers (ages 21-33). Subjects underwent induced hypoxia (70-100% SaO2) under steady-state conditions. Accuracy compared against reference CO-Oximetry. Results demonstrated SpO2 accuracy within ±3% over the 70-100% range. No adverse events reported.

Technological Characteristics

Battery-powered (2 AAA) fingertip device. Materials: ABS plastic enclosure, laser-etched medical silicone gel cushion. Sensing: Dual-wavelength (660nm/940nm) LED and photodetector. Connectivity: Standalone. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, ISO 80601-2-61, ISO 10993.

Indications for Use

Regulatory Classification

Identification

An oximeter is a device used to transmit radiation at a known wavelength(s) through blood and to measure the blood oxygen saturation based on the amount of reflected or scattered radiation. It may be used alone or in conjunction with a fiberoptic oximeter catheter.

### 3.4Device Description

The proposed device of Fingertip Pulse Oximeter MD300CL37 is a battery powered fingertip device, which can detect, display the measured %SpO2 and pulse rate value. The device is normally applied to adult, adolescent, child and infant patient in hospitals, hospital-type facilities, and home environments.

The proposed device consists of power supply module, detector and emitter LED, signal collection and process module, display module and user interface.

The Pulse Oximeter works by applying a sensor to a pulsating arteriolar vascular bed. The sensor contains a dual light source and photo detector. The one wavelength of light source is 660nm, which is red light; the other is 940nm, which is ultra red light. Skin, bone, tissue, and venous vessels normally absorb a constant amount of light over time. The photodetector in finger sensor collects and converts the light into electronic signal which is proportional to the light intensity. The arteriolar bed normally pulsates and absorbs variable amounts of light during systole and diastole, as blood volume increases and decreases. The ratio of light absorbed at systole and diastole is translated into an oxygen saturation measurement. This measurement is referred to as SpO2.

The power sources of the proposed device are 2 AAA alkaline batteries. The proposed device have low battery voltage indicator function and the proposed device will automatically power off when there is no signal for longer than 8 seconds. When the finger is placed into the device, the device will be powered on automatically.

The proposed device is not for life-supporting or life-sustaining, not for implant. The device or transducers are not sterile and the transducer is reusable and does not need sterilization or re-sterilization. The device is for prescription. The device does not contain drug or biological products.

The device is software-driven and the software validation is provided in Section of Software.
