Intended Use

Caremed Disposable SpO2 Sensors are indicated for continuous non-invasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR) for adult, pediatric and infant patient populations.

Device Story

Disposable SpO2 sensors function as accessories to patient monitors (e.g., Nihon Kohden BSM-5135A) for continuous non-invasive monitoring of arterial oxygen saturation and pulse rate. The sensor probe, applied to a patient's finger, contains two LEDs (red 660-666nm, infrared 880-950nm) and a photodiode. The device operates via 2-wavelength relative optical absorption; the photodiode detects light intensity changes caused by pulsatile blood flow. These electrical signals are transmitted to the host oximeter, which amplifies the signal and applies an algorithm to calculate SpO2 based on the ratio of oxygenated to total hemoglobin and pulse wave crest/trough absorbance. Used in clinical settings, the output provides real-time oxygenation and heart rate data to healthcare providers to assist in patient monitoring and clinical decision-making.

Clinical Evidence

Clinical accuracy was validated in human adult volunteers under controlled hypoxia conditions per ISO 80601-2-61:2017. Accuracy was compared against arterial oxygen saturation (SaO2) measured by co-oximetry. Results support the claimed SpO2 accuracy of ±3% and PR accuracy of ±3 bpm within the specified ranges.

Technological Characteristics

Disposable sensor with non-woven patient-contacting material. Sensing via 2-wavelength optical absorption (Red 660-666nm, IR 880-950nm) using a photodiode. Connects to host monitor via DB9M connector and adapter cable. Complies with IEC 60601-1 (electrical safety), IEC 60601-1-2 (EMC), and ISO 80601-2-61 (pulse oximeter performance). Biocompatibility per ISO 10993-5 (cytotoxicity) and ISO 10993-10 (irritation/sensitization).

Indications for Use

Indicated for continuous non-invasive monitoring of SpO2 and pulse rate in adult (>40 kg), pediatric (10-40 kg), and infant (3-15 kg) patients.

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.

It is comparable to the following legally marketed system: - 1. UNIMED MEDICAL SUPPLIES INC. Unimed Disposable and Reusable SpO2Sensors under K142832. #### 5. Device Description The proposed device, Disposable SpO2 Sensors are accessories to the patient monitors, which are intended for continuous non-invasive monitoring of functional arterial oxygen saturation and pulse rate. The compatible patient monitor is Nihon Kohden BSM-5135A. {4}------------------------------------------------ The sensor shall be connected to its corresponding monitor through Caremed adapter cable model SZ30-36. Oxygenation of blood is measured by detecting the infrared and red-light absorption characteristics of deoxygenated hemoglobin and oxygenated hemoglobin, which consists of a probe attached to the patient's finger. The sensor is connected to a data acquisition system which is used to calculate and display oxygen saturation levels and heart rate conditions. Each sensor has two LEDs, emitting both red and infrared light, and a photodiode. Red and infrared light lit alternately according to certain sequence, when the fingertips of capillary repeatedly with the heart pumps blood congestion, light emitting diode after blood vessels and projected onto a photodiode, photodiode can be induced to change with pulse light intensity, the electrical signals in the form of change. Then the received signal is forwarded to the corresponding oximeter that amplifies the signal and an algorithm that calculates the ratio. By measuring the wave crest of the pulse wave and the absorbance of the trough, SpO2 is calculated to obtain the correct oxygen saturation value. The saturation value is determined by the percentage ratio of the oxygenated hemoglobin (HbO2) to the total amount of hemoglobin (Hb). | Model | Measurement site | Intended population | |---------|------------------|------------------------------------| | C503-16 | Fingers | Adult (>40 kg) | | C523-16 | Fingers | Pediatric (10 kg < weight < 40 kg) | | C533-16 | Fingers | Infant (3 kg < weight < 15 kg) | | C543-16 | Finger | Adult (> 40 kg) | #### 6.
