Abstract:

Today´s problem is quarantine. During quarantine measures for elderly patients and patients with high fever, access to the clinic is limited. Therefore, the interaction with the family doctor requires as many physiological indicators as possible for a correct diagnosis. But to provide all patients with Holter monitoring devices is quite expensive for the state, so it is necessary to develop a low-cost device. The purpose of the study is to develop a pulse wave monitoring device. To achieve this goal it is necessary to solve the following tasks: 1. Conduct a literature analysis of heart rate monitoring methods; 2. Develop a schematic diagram of a heart rate monitor based on the ATmega328P controller. 3. Simulate the device in the ISIS Proteus software. 4. Calculate the accuracy and reliability of the results. The choice of ATmega328P controller is explained by the following considerations Literature analysis has shown that it must be simple to design a device that can be used by the elderly. This is a MegaD-328 device. The word "mega" has a double meaning. On the one hand, this indicates the wide capabilities of the device, on the other hand, indicates the microprocessor used in the module Atmega328. The MegaD-328 module is a device that can operate in both decentralized and centralized circuits. The user uses the Web interface to configure the device so that when you press the button, turn on certain connected devices. At the same time there is a possibility of remote control of the connected loadings and change of logic of work by means of the Web-interface built in MegaD-328. the user can work through his iPhone, HTC or Samsung with a beautiful Web-interface of the server, and the server in turn will transmit commands to MegaD-328 devices over Ethernet. Low sensitivity to interference, built-in anti-collision mechanism. To analyze the signal conversion, use the program Labview.
