Description

Patient heart rate/respiration measurement device of dental chair using radar {APPARATUS FOR MEASURING PATIENT HEARTBEAT/RESPIRATION OF DENTAL CHAIR USING RADAR}

The present invention relates to an apparatus for measuring patient heart rate/breathing of a dental chair using a radar, and more particularly, a heart rate and/or through displacement of a patient's chest present in a dental chair in a non-contact manner using a radar at a short distance. It relates to a device for measuring respiration.

In general, a biological signal such as respiration rate is one of the most convenient factors for diagnosing a human body's health status and abnormalities. Mainly in critically ill patients, emergency patients, patients during surgery, patients after surgery/treatment/test/recovery, or the elderly who are vulnerable to health maintenance, a biosignal meter (e.g., a respirator) is attached to continuously check vital signs.

For example, an oxygen mask is attached to a patient undergoing surgery to continuously check the patient's breathing status during surgery.The oxygen mask can give the patient a sense of fear, and a large number of connecting wires connecting the breathing status monitoring device together with the oxygen mask As a result, there was an inconvenience in the procedure or operation due to restrictions on the movement of medical staff such as doctors.

In addition, it is often necessary to check the breathing status of not only patients who are hospitalized or undergoing surgery, but also those who live outside the hospital. For example, it is necessary to measure the breathing patterns of the elderly with unstable breathing patterns or of infants living in a different space from their parents or during sleep.

In particular, in recent years, it is necessary to measure the actual respiration rate or respiration volume and use it to diagnose a person's health condition, in addition to the degree of diagnosis of sleep apnea, which is a disease that temporarily does not breathe during sleep.

However, in the related art, it has been difficult to obtain data by accurately measuring a user's respiration rate and respiration volume without a respiration measuring device such as that provided in a hospital, and to accurately transfer the acquired data to a doctor in a hospital.

In particular, the conventional method of measuring the respiration rate by attaching a simple sensor to the body and using the primary signal obtained from the sensor is much insufficient in accuracy compared to the method of measuring the respiration rate through hospital equipment. .

In order to solve this problem, in Korean Patent Registration No. 10-1654914 (a breathing measuring device and a breathing measuring method using the same), a pad attachable to the user's body, installed on the pad, and the user's breathing Three or more sensors for measuring signals generated according to the user's body movement, and a determination unit for measuring the user's respiration rate using signals measured by at least two or more of the three or more sensors, The sensor includes a first sensor and a second sensor, and the determination unit compares the first signal measured by the first sensor and the second signal measured by the second sensor, and within a time difference of a preset range. By counting the number of times the peak values of the first signal and the second signal appear and counting the number of respirations, a respiration measurement device capable of accurately and simply measuring the user's respiration rate is disclosed.

In this prior art, it is possible to remotely check the user's health status in real time by transmitting the user's breathing data during daily life outside the hospital to a system such as a hospital, and the user's respiratory rate without attaching equipment such as an oxygen mask to the user. By measuring, there is an advantage of being able to monitor the patient's breathing state in real time in parallel with surgery and various treatments.

However, in the conventional respiration measuring device and respiration measuring method, as a contact type device attached to the user's body, it has a limitation that it cannot measure respiration unless the user wears it.
