- 1) ISO 81060-2: 2018 Non-invasive sphygmomanometers Part 2: Clinical investigation of intermittent automated measurement type
- 2) ISO 80601-2-56: 2017+AMD1: 2018 Medical electrical equipment Part 2-56: Particular requirements for basic safety and essential performance of clinical thermometers for body temperature measurement.

The Multi-parameter detector integrates an FDA market cleared devices, All-in-One Health Monitor (K170047) for measurement of oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR). The SpO2 and PR cleared under K170047 were originally cleared under K063641, which is in compliance with ISO 9919: 2005.

The pulse oximeter accuracy was tested in ten healthy subjects, aged 22-40, with skin tones varying from Fitzpatrick 2-6. 3 subjects had dark skin with Fitzpatrick 5 or 6. The Arms of 70%-100% is 1.49, it meets the accuracy claims of ±3%.

Therefore, there is no test of these two parts (SpO2 and PR) in this clinical test.

Clinical testing has been performed under an approved protocol with subject informed consent. Clinical test results support device accuracy claims for the specified measurement range.

The Clinical studies was a single-center, randomized, self-controlled clinical trial for accuracy validation. Compared with registered mercury thermometer and desktop sphygmomanometer, the accuracy of body temperature and blood pressure measurement was used as the main effectiveness observation indications, and easy for use and device stability were used as the main safety observation indications to evaluate the safety and effectiveness of the Multi-parameter detector (body temperature and blood pressure) produced by Zhongshan Jinli Electronic Weighing Equipment Co., Ltd.

In the evaluation of the accuracy of temperature measurement, 105 subjects did not exceed the maximum allowable error of ±0.2℃ in the temperature display range of 35.0 ℃~ 42.0 ℃, and the clinical repeatability did not exceed the range of ±0.3 ℃, which met the temperature measurement standards.

In the evaluation of the accuracy of Blood Pressure Measurement, a total of 119 subjects completed the experiment. The average value of the difference between the blood pressure value (systolic or diastolic blood pressure) measured by the test device and the reference blood pressure measurement value is within the range of ±5.0mmHg, and the standard deviation is not greater than 8.0mmHg, which meets the standard requirements.

{12}------------------------------------------------

Zhongshan Jinli Electronic Weighing Equipment Co., Ltd.

The interface friendliness of the device and the satisfaction rate of the operation response time were both 100.00%. The satisfaction rate of the whole device function and stability evaluation index was 100.00%. There were no adverse events and serious adverse events in the clinical trial, and the incidence rate was 0.00%, and the device has good safety.
