Abstract

Information can now be transferred more easily and rapidly than in the past because of technological developments. The network or Ethernet platform is one of the safest and fastest methods for receiving and transmitting data across long distances. Vital body signs, such as heart rate (HR) and blood pressure (BP), are examples of important information that may be transmitted via the network between the patient and the medical staff, allowing the medical team to monitor the patient’s health status remotely. In this study, a system was designed that records the Electrocardiogram (ECG) and BP, then sends the data through a network connection via a serial to Ethernet converter (WIZNET). An atmega32 microcontroller was used to receive and process data from both analog channels, and the microcontroller also sent digital data to the Ethernet converter via a serial port. In LabVIEW software, an interface was created to display signals. In this way, the ECG and BP are presented online and at regular intervals, respectively. This system’s performance was evaluated on 15 healthy persons for 45 minutes. This system may effectively handle the demand for medical staff to remotely access patients’ vital signs in hospitals or medical centers. As a result, promoting such systems can effectively reduce treatment time and costs, therefore increasing the treatment process’s efficiency.

Introduction

In situations when there is limited space for the patient to be hospitalized or the patient is placed far away from the physician,
telemedicine technology can deliver all vital signs to the medical team at the same time. In the case of a pandemic, the technology
will be able to send vital patient information to a patient monitoring center in a hospital or clinic through the internet.
Thus, disruptions in treatment procedures caused by patient congestion will be avoided. In this article, a system has been
devised and developed in which the patient’s heart ECG and blood pressure signals are recorded, transmitted on the Ethernet
network, and displayed on a computer or computers situated anywhere in the hospital.

The block diagram of the proposed system

RESULT

The LabVIEW interface was executed by pressing the RUN key in the front panel. If properly connected to the serial to
Ethernet converter, the real-time ECG was displayed at the intended location and the blood pressure signal was updated and
displayed every 15 minutes. Also, according to the description in the method section, the output of heart rate per minute block diagram was displayed in the specified section. Finally, if the medical staff required it, the ECG and blood pressure data were
saved to the computer memory in txt format by pressing the data save key on the front panel. Figure 5 shows an example of a front panel related to ECG and blood pressure display in the LabVIEW software for one of the research tests.
