K011291 - TEMPORALSCANNER THERMOMETER, SENSORTOUCH; EXERGEN CORP.

#### Indications for Use:

The Accutorr 7/VS-900/VS-900c Vital Signs Monitor is intended for monitoring physiologic parameters, including Pulse Oximetry (SpO2), Pulse Rate (PR), Non Invasive Blood Pressure (NIBP), Temperature (TEMP) and Carbon Dioxide (CO2) on adult, pediatric, and neonatal patients in professional healthcare facilities by clinical physicians or appropriate medical staff under the direction of physicians.

- The monitor also provides a Modified Early Warning Score (MEWS) for clinical assessment in adult patients.

{5}------------------------------------------------

#### Device Description:

The Accutorr 7/VS-900/VS-900c Vital Signs Monitors are composed of the main unit and parameter modules. The main unit has the following functions:

- Provides operation interface, such as keys, touchscreen, and display screen. ●
- Communicates with the parameter modules. ●
- Delivers the setup commands of parameters to the parameter modules. ●
- Obtains the parameter measurements. ●
- Displays and stores the parameter numeric measurements and waveforms, and sends the data to Mindray's central monitoring system or Mindray's eGateway.

The parameter measurement modules include Pulse Oximetry (SpO2), Pulse Rate (PR), Non Invasive Blood Pressure (NIBP), Temperature (TEMP) and Carbon Dioxide (CO2). Their measurement principles are as follows:

Pulse Oxygen Saturation (SpO2) monitoring is a non-invasive technique used to determine the amount of oxygenated hemoglobin and pulse rate by measuring the absorption of selected wavelengths of light. The light generated in the emitter side of the probe is partly absorbed when it passes through the monitored tissue. The amount of transmitted light is detector side of the probe. When the pulse active part of the light signal is examined, the amount of light absorbed by the hemoglobin is measured and the pulse oxygen saturation can be calculated. The SpO2 module processes the electrical signal and displays a waveform and numeric values for SpO2 and pulse rate.

The monitor uses the oscillometric method for measuring the non-invasive blood pressure (NIBP). NIBP measurement is based on the principle that pulsatile blood flow through an artery creates oscillations of the arterial wall. The oscillometric device uses a blood pressure cuff to sense these oscillations, which appear as tiny pulsations in cuff pressure. The Oscillometric devices measure the amplitude of pressure changes in the occluding cuff as the cuff deflates from above systolic pressure. The amplitude suddenly increases as the pulse breaks through the occlusion in the artery. As the cuff pressure decreases further, the pulsations increase in amplitude, reach a maximum (which approximates to the mean pressure), and then diminish. The oscillometric method measures the mean pressure and determines the systolic and diastolic pressures.

CO2 monitoring is based on measuring the absorption of infrared (IR) light of specific wavelengths. CO2 has its own absorption characteristic and the amount of light passing to the gas probe depends on the concentration of the measured CO2. When a specific band of IR light passes through respiratory gas samples, some of the IR light will be absorbed by the CO2 molecules. The amount of IR light transmitted after it has been passed through the respiratory gas sample is measured with a photodetector. From the amount of IR light measured, the concentration of CO2 is calculated.

The monitor supports two kinds of TEMP module: Mindray TEMP and Exergen TEMP. Different TEMP modules cannot be used at same time. The customers need to choose one kind of TEMP module before they buy the monitor.

{6}------------------------------------------------

- Mindray TEMP Module has two measuring modes, Monitor mode and Predictive mode. ● In the Monitor mode, the thermal resistance in the probe reflects the subject's temperature by sensing the temperature change of the subject according to the thermal equilibrium principle. In the Predictive mode, the subject's temperature is predicted by the temperature rise curve (which is obtained by collecting multiple temperature measurements) at the time of initial thermal conduction.
- The Exergen Temperature Module is an infrared thermometer designed for accurate and completely non-invasive temperature assessment by scanning the temporal artery (TA). Temperature is measured by gently swiping the Temporal Scanner across the forehead, and includes a momentary touch of the probe to the neck area behind the ear lobe to account for any cooling of the forehead as a result of diaphoresis. The patented arterial heat balance technology (AHB™) automatically measures the temperature of the skin surface over the artery and the ambient temperature. It samples these readings approximately 1000 times a second, ultimately recording the highest temperature measured (peak) during the course of the measurement. The Temporal Scanner emits nothing - it only senses the natural thermal radiation emitted from the skin.

#### Non-clinical testing:

EMC and Electrical Safety - To establish the substantial equivalence of the subject Accutorr 7/VS-900/VS-900c Vital Signs Monitor to the previously cleared Accutorr 7/VS-900 Vital Signs Monitor (K170712), Mindray conducted Electromagnetic Compatibility and Electrical Safety testing level testing on the subject device. The testing provides an evaluation of the EMC and electrical safety of the subject devices relevant to each of the modifications since clearance of the predicate Accutorr 7/VS-900 Vital Signs Monitor. The Electromagnetic Compatibility and Electrical Safety testing shows that the subject device continues to meet the specifications and the performance of the subject device is equivalent to the predicate device.

#### Substantial Equivalence Conclusion:

Based on the detailed comparison of specifications for each of the modifications to the primary predicate device (Accutorr 7/VS-900) (K170712) and the secondary predicate device (Exergen Temporal Scanner Thermometer )(K011291), and the performance testing and conformance with applicable standards, the subject device (Accutorr 7/VS-900/VS-900c) can be found substantially equivalent to the primary predicate device.
