Chapter 4 Structural Features and Working Principle 4.1. Overall structure framework chart Figure 4.1 Overall structure framework chart 4.2 Principle of blood pressure measurement The product is designed to calculate the blood pressure I terms of conduction time of pulse and wave parameters of pulse. This method is proposed based on interdependent characteristics between conduction time of the pulse wave along the arterial as well as characteristic parameters of the pulse wave and arterial pressure. Through the determination of the PPG signal, conduction time of the pulse wave along thee arterial and other correlation variables would be obtained and accordingly the systolic and diastolic pressures of the body are gotten by fitting operation. The pulse rate can be obtained by calculating the pulse wave signal.Button operation OLED display Network communication Central processing unit (CPU) Storage Blood pressure circuit template Battery Functional accessories Pulse wave probe Charger

Note: UT refers to AC network voltage before test voltage is applied. The guidance and manufacture’s statement–electromagnetic immunity Users or buyers of the equipment should make sure that it is used in such following electromagnetic environment: Immunity test IEC 60601 test level Accord with level Electromagnetic immunity–guidance RF conduction GB/T 17625.6 3 Vrms 150 kHz to 80 MHz 3 V/m 80 MHz to 3 Vrms 3 V/m Portable and mobile RF communications devices shall not be used closer to any part of the equipment (including the cable) than the recommended isolation distance. The distance shall be calculated by the formula corresponding to the transmitter frequency. Recommended isolation distance d = P2.1 d = P2.1 80 MHz to 800 MHz d = P3.2 800 MHz to 2,5 GHz Among them, P refers to the maximum output power rating of the transmitter, which is provided by its manufactures. Watt (W) is a unit, D is recommended isolation distance, and meters (m)is a unit.
RF radiation GB/T 17626.3 2,5 GHz The field strength of the fixed RF transmitter is determined by the electromagnetic field survey a, and in each frequency range the B should be lower than the level required. Interference may occur near the equipment that marks the following symbols. Note 1：On the 80MHz and 800MHz, formulas of higher frequency bands are employed. Note 2：The guidance may not apply to all the situations because electromagnetic transmission is influenced by the absorption and reflection of buildings, objects, and the human body. a The field strength of the fixed transmitter, such as wireless (cellular / cordless) telephone, the base station of ground mobile radio, amateur radio, AM as well as FM radio and television broadcasting, cannot be theoretically predicted. In order to evaluate the electromagnetic environment of a fixed RF transmitter, the investigation of electromagnetic field should be conducted. If the field strength of the device is higher than the RF level of the above-mentioned application, the equipment shall be observed to verify its normal operation. If abnormal performance is observed, supplementary measures may be necessary, including reorientation or repositioning of the equipment. b In the whole frequency range of 150 kHz to 80 MHz, the field strength should be less than 3 V/m. Recommended isolation distance between portable and mobile RF communications devices and Discovery 1 The device is expected to be used in a controlled electromagnetic environment where radiated RF is disturbed. On the basis of the maximum output power of communication equipment, purchasers or users of Discovery 1 can maintain the minimum distance between Discovery 1 and portable and mobile RF communication equipment (transmitter) and accordingly prevent electromagnetic interference. Rated maximum output power of transmitter /W Isolation distance corresponding to different frequencies of transmitter 150 kHz ～ 80 MHz d = P2.1 80 MHz ～ 800 MHz d =P2.1 800 MHz～ 2,5 GHz d = P3.2 0.01 0.12 0.12 0.23 0.1 0.38 0.38 0.73 1 1.2 1.2 2.3 10 3.8 3.8 7.3 100 12 12 23
Rated maximum output power of transmitter can be defined by related formulas of transmitter frequency bar. Recommended isolation distance could be represented by d and the unit is meter. P represents Rated maximum output power of transmitter, which is provided by its manufactures. Watt (W) is a unit. Note 1: on a frequency range of 80 MHz and 800 MHz, a formula with a higher frequency range is adopted Note 2：The guidance may not apply to all the situations because electromagnetic transmission is influenced by the absorption and reflection of buildings, objects, and the human body.
