Abstract

PURPOSE: A Doppler vital signal measurement instrument is provided to easily inspect and search for the signal by using a bio-signal remotely measured . CONSTITUTION: A mainboard(M2) supplies power to a transceiver module(M1). The module irradiates a 10 GHz frequency signal to a chest part of a patient. The irradiation is formed through a horn antenna(A1). Respiration and pulsation measurement values of a patient are transmitted to a remote server. The measurement values are formed through the horn antenna and Doppler effect.

Description

Vital Signal Measuring Instrument with Doppler effect

The present invention relates to a vital signal (biosignal) measuring device. Specifically, a 10-GHz band Doppler radar using a horn antenna and a main board equipped with a signal measuring algorithm, and a communication module for transmitting the same to the server are unbounded and unbounded. The present invention relates to a vital signal measuring device capable of measuring biosignals such as breathing and pulse signals of a patient in an invasive form.

Conventional patient bio-signal acquisition has a Patient Monitoring System that acquires sensors by attaching them to the chest, fingers, etc. of the patient. This limits the movement of patients and cannot be used in the u-Health field to prevent the death of the elderly living alone. In addition, only one patient per device is difficult to measure signals, which makes it difficult to diversify the use of biological signals (eg anti-terrorism prevention systems such as airports and government offices).

Non-invasive, non-binding benefits to patients and non-contact bio-signal measuring device is necessary to enhance the multi-purpose application using bio-signals.

An object of the present invention is to provide a vital signal measuring device for measuring a signal in a non-contact, non-invasive, non-binding form in the acquisition of a bio-signal, so that it can be used in the medical service field and other industries using bio-signals.

In order to measure respiration / pulse of the biological signals, the present invention focuses the RF of the 10 GHz band using a horn antenna and detects a signal using a Doppler effect, which is solved by detecting respiratory rate and pulse rate on the main board. It was. In addition, it is possible to remotely transmit the bio-signal through the IEEE 802.11 b / g type of wireless LAN to provide additional services.

According to the present invention, in the field of medical services, it is possible to acquire the biosignals necessary for medical staff while providing the advantages of non-compliance, non-invasive, and non-contact to the patient, thereby contributing to the profit creation of medical institutions through the promotion of medical services.

It can also be used to detect suspected terrorist areas or suspected terrorist threats, such as airport checkpoints and government office entrances, using biometric signals measured remotely. In the case of human beings, there is an example of utilizing the fact that breathing / pulse changes when a check / search is performed.

In addition, physically providing external I / O ports to expand additional sensors (e.g. infrared sensors) enables the measurement of animals' biological signals in hazardous areas.

1 is a general schematic diagram of the Doppler vital signal meter and shows the concept of Doppler effect and system configuration.
2 shows a hardware block diagram of a Doppler vital signal meter.

The present invention has been devised to overcome the disadvantages of the existing form of the patient bio-signal measuring device, which is the main equipment of the medical service, and to improve the utility of various fields using the bio-signal.

In the present invention, to measure the respiration / pulse of the biological signal, the radio frequency of 10GHz band is irradiated to the chest of the patient as shown in Figure 1, the difference of the signal reflected by the movement of the patient (heart beat or chest movement due to breathing) Is a concept that detects through Doppler effect and extracts breath / pulse rate from mainboard and transmits itself to remote server.

As shown in FIG. 2, the hardware of the measuring instrument is mainly composed of horn antennas A1 and A2, a transceiver module M1 of a 10 GHz band, a main board M2, and a wireless LAN antenna M7. The main board (M2) consists of the main CPU module (M3), the wireless LAN module (M4) in charge of communication, the display module (M5) to show the breathing / pulse rate, and the external I / O port (M6) for expansion. do.

When power is supplied to the meter, the main board M2 supplies power to the transceiver module M1. The transceiver M1 radiates a frequency of the 10 GHz band to the chest of the patient through the horn antenna A1 for Tx. The horn antenna A2 for Rx reaches the chest and receives the reflected signal. At this time, the horn antennas A1 and A2 mechanically focus on the chest of the patient. The transceiver module M1 filters the received signal of the 10 GHz band and transmits the signal to the main CPU module M3 of the main board M2. The main CPU module (M3) is equipped with a respiration / pulse measurement algorithm. Through this algorithm, the respiratory / pulse rate of the patient is calculated and transmitted to the display module (M5) for its own output, and the wireless LAN module (M4) for server transmission. Send to.

The wireless LAN module M4 transmits to a remote server through the wireless LAN antenna M7, and the display module M5 performs a function of expressing the respiratory rate and the pulse rate through the LED and the LCD.

The I / O port (M6) for expansion has GPIO, USB, etc. and includes a control chip for use in connection with an external sensor or device.
