The subject device Pulse Oximeter is a battery powered device, which can mainly detect and display the measured oxyhemoglobin saturation (SpO2) and pulse rate (PR) value. Place one fingertip into the photoelectric sensor for diagnosis and the pulse rate and oxygen saturation will appear on the display. The device is normally applied to infants, children, adolescents and adult in hospitals, hospital-type facilities and homecare. The subject device is composed of following components to achieve the above detection process: power supply module, detector and emitter LED, signal collection and process module (MCU), OLED/LED display screen, user interface and button control circuit.

WS20A is a pulse oximeter indicated for use in measuring, displaying, storing and transmitting functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate for patients(≥10 years old, ≥30kg). It is designed for finger circumference more than 33mm. It is intended for spot-check, continuous data collection, recording and transmitting, not continuous monitoring. It can be used in sleep labs, long-term care, hospitals and home.

Pulse Oximeter WS20A is an internally powered pulse oximeter. The main functions of the devices include hemoglobin oxygen saturation (SpO2), pulse rate (PR) measurements and Pulse amplitude index (PAI), data storage and transmission. Place one fingertip into the sensor and the oxygen saturation (SpO2), pulse rate (PR) measurements and pulse amplitude index (PAI) will appear on the display. The device is intended to be applied to adult and pediatric patients in sleep labs, long-term care, hospital and home care environment. The subject device is composed of the following components to achieve the above detection process: power supply module, detector and emitter, signal collection and process module (MCU), TFT display screen and Bluetooth module.

The pulse oximeter is indicated for continuous or spot check monitoring of functional arterial oxygen saturation (SpO2) and pulse rate of adult patients in hospitals and clinics.

The HS10A is a handheld, battery powered pulse oximeter used for monitoring of pulse rate and functional arterial oxygen saturation in arterial blood. The HS10A include the addition of audible alarms, addition of keys and display icons in the user interface board to access the alarm settings. The device also has menu features to allow the user to set the time, date and measurement alarm limits.

The Pulse Oximeter FS10A and FS20A are portable, non-invasive devices intended for spot check monitoring of arterial hemoglobin oxygen saturation (SpO2) and pulse rate of adult patients (weighing ≥ 30 kg) in hospitals.

The proposed devices of Pulse Oximeter FS10A, FS20A are fingertip devices, which can display SpO2 and pulse rate value. The proposed devices consist of detector and emitter LED, CPU, display unit and power unit. 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 wavelength of one light source is 660 nm, which is red light; the other is 906nm, which is infrared light. Skin, bone, tissue, and venous vessels normally absorb a constant amount of light overtime. 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 is translated into an oxygen saturation measurement. This measurement is referred to as SpO2. The power sources of the proposed devices are 2 AAA alkaline batteries. All of the proposed devices have low battery voltage indicator function and all of the proposed devices will automatically power off when there is no signal for longer than 8 seconds. The proposed devices are not for life-supporting or life-sustaining, not for implant. The devices or transducers are not sterile and the transducers are reusable and do not need sterilization. The devices are for prescription. The devices do not contain drug or biological products. The Pulse Oximeters FS10A,FS20A share the same measurement principle and oximeter sensor and oxygen saturation module and power supply. The indented target population and use environment of the Pulse Oximeters FS10A, FS20A are the same. The devices are software-driven and the software validation is provided in Section of Software.
