#### 2.5 Device Description:
The Arm-type Fully Automatic Digital Blood Pressure Monitor (BPM) series is automatic, non-invasive, blood pressure measurement system for over-the-counter (OTC) use at home and clinical environment . The systolic and diastolic pressures are determined using the oscillometric method, where the cuff is inflated with an integral controllable piezoelectric pump and deflates via an electric automatic rapid deflation valve. During inflation measurements, an electric pump within the main unit slowly inflates the arm cuff, generating cuff pressure which is monitored and from which pulse waveform data is extracted. This waveform data is analyzed by software algorithms within the microprocessor to determine systolic pressure, and diastolic pressure. The cuff can measure pressure range from 0 to 299mmHg.
Meanwhile, some models whith bluetooth function can be used as a stand-alone unit to finish the blood pressure measurement or in conjunction with the APP through embed a 2.4GHz BLE module that allow users to connect with nearby BT receiving terminal. Once measurement is over, the LCD of the device displays results. And the device will start to transmit data to the pair-up terminal automatically. This app is only intended to display measurement results from the blood pressure monitor device, which does not provide any diagnostic or measurement functions, and does not interpret or analyze the data for medical decision making. Unlimited readings can be stored in the app for archiving and review by the user.
There are total 7 arm-type blood pressure monitor models we submitted: DBP-62D0L, DBP-62D0B, DBP-61D0, DBP-61D0L, DBP-6293L, DBP-6193 and they are both bodyworn medical devices.

## 2.10. Discussion of Clinical Tests Performed:
Clinical Validation:
- ISO81060-2:2018+AMD2020 Non-invasive sphygmomanometers —Part 2: Clinical investigation of intermittent automated measurement type.
Model DBP-6279B was selected as representative for testing. It was conducted according to ISO 81060-2 Non-Invasive Sphygmomanometers - Part2: Clinical Investigation Of Automated Measurement Type. The subject demographics include total of 90 subjects meeting the inclusion criteria, all 90 include subjects are all older than 12 years.
Same arm sequential method was adopted during the clinical testing. The manual Mercury Sphygmomanometer was used as a reference device. All the subjects were volunteer to take part in the clinical study, all the subjects completed the clinical study without any AE or side-effect. The results showed the accuracy of the blood pressure monitor is within acceptable scope specified in ISO 81060-2:2018+AMD2020.
The applicable part of subject devices in this submission and previous arm-type blood pressure monitor models submitted by JOYTECH are both upper-arm. The only difference is that current subject devices are body-worn but previous submitted are portable. All new design elements have been successfully validated and the results fully demonstrate that the device has good safety and effectiveness.
Meanwhile, through the verification of internal simulation tests, it prove that even if the appearance is different, but in the case of the same algorithm, the performance of the DBP-6279B and the current submitted models are the same. There is no need to carry out clinical research on the new design, and the clinical results of DBP-6279B can cover the current submitted models.
# 2.11. Conclusions:
The subject device and predicate devices have same Measuring principle, measuring method, are designed for the measurement of blood pressure in adult population for home use. The minor difference between the subject devices and the predicate devices have been evaluated and determined to not raise any new issues of safety or effectiveness.
