When you connect them, you could hear "Kaka". As shown in Figure 2.3, the finger of the person to be measured (using the index finger of the left hand) is extended into the probe. Figure 2.3 the finger position of wearing the clip pulse wave probe Safety attentions for pulse wave measurement Before the use, please check the pulse wave probe and if there is worn cable or abnormality, please immediately stop using the equipment. Do not place the pulse wave probe on the limb with an artery or venous infusion tube because such circumstance will affect the accuracy of measuring results. Do not look directly at the pulse wave probe when using it in order to avoid the damage to eyes. Please stop using the probe if you find out its temperature is obviously increasing. Please do not use the pulse wave probe for a long time when the ambient temperature is above 40 degrees in order to avoid burns. Normally, at least once every 3 hours, change the wearing position. Inspect the worn area every 1 to 2 hours to ensure good skin condition is aligned with the correct light. If local skin condition changes, please change the position of the pulse wave probe in time. Constant use of the pulse wave probe can cause discomfort or tenderness, especially in patients with microcirculatory disturbances, so preferably change the wearing position once every 2 hours. As for some special patients, the measuring part of the pulse wave probe should be checked carefully and do not place the sensor in a edematous or fragile tissue!

Those who are measured should not have long fingernails and apply nail polish, etc. If those who are measured have thick callus of fingers, the finger with less callus is preferred. Do not bend, twist cable. The blood pressure cuff and pulse wave sensor that need to be pressurized cannot be used on the same limb because measuring the blood pressure on the same limb will affect the monitor of pulse wav. Do not use the broken pulse wave probe. Do not completely put the probe into the water, solution or cleaning agent because the probe is lack of waterproof function. Please hold the forepart of the plug to pull the plug. The pulse wave probe can be used repeatedly. Before that, the probe needs cleaning. The specific methods are described in a chapter related to maintenance. In order to ensure the safety and effectiveness, its necessary to use the pulse wave probe provided by our company and stop the interface of the pulse wave probe from being connected to other things.

Overall structure framework chart Button operation OLED display Network communication Central processing unit (CPU) Storage Blood pressure circuit template Battery Functional accessories Pulse wave probe Charger 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. Chapter 5 Technical Characteristics 5.1 Blood pressure 1.

Watt (W) is a unit, D is recommended isolation distance, and meters (m)is a unit. P2.1P2.1P3.2 RF 2,5 GHz The field strength of the fixed RF transmitter is radiatio n GB/T 17626.3 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 1On the 80MHz and 800MHz, formulas of higher frequency bands are employed. Note 2The 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.

Warranty card Users information Name of the equipment Type of the equipment Number of the equipment Purchase date Users name Telephone Warranty record Warranty date Failure and processing method Repairer /date FCC Caution This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

-Reorient or relocate the receiving antenna.

-Increase the separation between the equipment and receiver.

-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

-Consult the dealer or an experienced radio/TV technician for help. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled Environment and can be use without any restrictions.
