Description

Patients Monitoring System {Patients Monitoring System}

The present invention relates to a patient monitoring system, and more particularly, to a patient monitoring system capable of promptly notifying by monitoring the presence of abnormalities or accidents such as bedsores, fever, and falls of the patient in real time.

In general, for hospitalized patients, regular visits by a doctor in charge (once a day) and visits for treatment purposes by a nurse (eg, fluid, body temperature measurement, blood pressure check, etc.) are made. Therefore, for other times, only the patient and the guardian remain, and in particular, when the guardian is away or absent, the patient is alone.

Depending on the patient's condition, it is necessary to continuously measure the body temperature to closely monitor the presence of fever, and in some cases, immediate action is required if fever occurs. However, in reality, it is difficult for a nurse to stand by while measuring only body temperature.

In addition, in the case of a long-term hospitalized patient or an elderly patient, bedsores tend to occur on the back, buttocks, arms, etc. because they live in bed. To prevent this, the patient must change his or her posture little by little or lie down. Even in this case, it is difficult for the nurse to continue to change the patient's posture while standing by the side. In addition, in the case of a dedicated caregiver who is a non-professional, pressure sores may occur due to irregular posture change cycles.

On the other hand, falls accidents frequently occur due to various factors, such as when a patient turns while sleeping, causes seizures, or feels dizziness while causing upper body (eg, orthostatic hypertension). In particular, fall patients are not immediately detected, but are found late, further exacerbating the condition or leading to death in severe cases.

That is, there is a need for a system that monitors the patient in real time near the patient to prevent fever, bedsores, and falls. However, the CCTV installed in the hospital room only photographs the apparent state of the patient, so it cannot cope with bedsores or fever. In addition, since there are dozens to hundreds of patients, it is even more impossible for an administrator to determine the patient's condition individually while viewing all images.

Example of Configuration

Hereinafter, a configuration of a preferred embodiment will be described in detail with reference to the accompanying drawings.

1 is a front view showing a state of use of a patient monitoring system according to an embodiment of the present invention, FIG. 2 is a schematic block diagram of the monitoring system shown in FIG. 1, and FIG. 3 is a diagram of the monitoring system shown in FIG. It is a side view.

1 to 3, the bed 20 maintains a predetermined height from the floor 10 and is movable with wheels. The patient 50 can lie on the bed 20, and foldable armrests 30 are installed on both sides to prevent falls.

The plate 40 is installed on the foot of the patient 50, and can be used as the plate 40 by rotating with respect to the bed 20 or can be tilted.

The medical console 100 is installed on the wall of the upper part of the patient's head. The camera 150 is preferably an infrared camera capable of photographing from the center of the console 100 to the bottom. The photographing area 170 of the camera 150 employs a wide-angle lens so that the entire body of the patient can be photographed. In particular, since the captured image is a distorted image, it can be corrected like an image taken from the ceiling through a separate image correction.

The medical console 100 is equipped with a power supply 110, an upper light 120, and a lower light 130, and in addition, oxygen supply, suction, a medical equipment holder, a microphone, and an emergency button are installed.

In FIG. 3, the control unit 200 may be a CPU or a microcomputer of a computer. A program is installed in the control unit 200 to determine and notify whether an event to be described later has occurred.

The bedsore event program installed in the control unit 200 warns of the occurrence of bedsores when there is no movement of the patient 50 in the image for a predetermined time (eg, 30 minutes to 1 hour). To this end, the bedsore event program extracts the contour line 260 from the image, and may warn when the contour line 260 moves finely or does not move within a narrow range.

The heating event program installed in the control unit 200 warns of occurrence of heat when the maximum temperature in the image is higher than a predetermined temperature (eg 38 degrees). To this end, the heating event program detects the temperature of a predetermined area (eg, head, hand) or the highest heating area from the infrared image. In the present embodiment, three temperatures were measured, but the location or number of measuring temperatures may be changed.

The fall event program installed in the controller 200 warns of the occurrence of a fall when the position of the patient 50 in the image is out of a predetermined range. That is, a normal image as shown in FIG. 6A is used as a reference image, and a fall is determined by comparing the image as shown in FIG. 6B with FIG. 6A. Here, the predetermined range is the bed 20. To this end, the contours of the patient 50 and the bed 20 can be derived and used.

The communication unit 240 may transmit an image of the camera 150 and a determination result of the control unit 200 to the outside, and may receive data from the outside. To this end, the communication unit 240 includes wired communication (eg, Internet modem) and/or wireless communication (Wi-Fi, 3G, 4G, 5G public communication network, telephone network, wireless Internet, Bluetooth, Zigbee, beacon module, etc.).

The patient information unit 250 is a database including information on a patient's name, sex, social security number, age, ID, hospital subject, condition, doctor, hospitalization date, precautions, contact information, and the like. When an event occurs, the patient information unit 250 provides information of a corresponding patient to the control unit 200 so that it can be displayed on the display 230.

The camera 150 is an infrared camera or a visible ray camera, installed for each patient, and transmits an image to the center. Therefore, the camera 150 may be installed as many as the number of patients or the number of beds.

The storage unit 210 is a component for storing an image of the camera 210 and an event occurrence record. The storage unit 210 may be implemented as a hard disk, SSD, flash memory, or the like.

The alarm unit 220 serves to promptly notify an administrator or a medical professional when an event occurs. To this end, the alarm unit 220 focuses attention with a buzzer, a speaker, a warning light, or displays a warning character or a flashing character on the display 230.

The display 230 may be a TV or a monitor. 4 is an image when a bedsore event occurs among images monitored according to an embodiment of the present invention. On the top of the display 230, the ID of the camera 150 and the body temperature of the patient 50 measured at three locations are displayed. The body temperature of the patient 50 may be measured by determining a point from the thermal image of the infrared camera 150. The three places where body temperature is measured can be changed to exposed areas such as the head and hands, and clothing such as patient clothing or other parts.

The alarm unit 220 is displayed in the middle area of the display 230, but is not displayed when it is normal, and the event contents are displayed in red only when an event occurs.

An image captured by the camera 150 is replayed in real time from the middle to the bottom of the display 230. In FIG. 4, the image of the patient 50 lying on the bed 20 is displayed as an infrared thermal image.

Example of action

Hereinafter, the operation of the preferred embodiment will be described in detail with reference to the accompanying drawings. 7 is a flowchart showing a patient monitoring method according to an embodiment of the present invention. As shown in FIG. 7, first, the infrared camera 150 photographs the patient 50 lying on the bed 20 and outputs a thermal image to the controller 200 (S100). At this time, the storage unit 210 records the thermal image in real time.

Then, the controller 200 determines whether there is motion in the image for a predetermined time (eg, 30 minutes to 1 hour) (S120). If there is no movement, the alarm unit 220 outputs a bedsore event as shown in FIG. 4 (S130). At this time, as shown in FIG. 4, even an alarm “a bed sore event has occurred” is also recorded in the storage unit 210. Optionally, a beep sound can be output from a buzzer or speaker.

When there is no bedsore event, the controller 200 determines whether the temperature in the image is equal to or higher than a predetermined temperature (eg, 38 degrees) (S140). If the measured temperature is equal to or higher than the predetermined temperature, the alarm unit 220 outputs a heating event as shown in FIG. 5 (S150). At this time, as shown in FIG. 5, even the alarm “heating event occurs” is also recorded in the storage unit 210. Optionally, a beep sound can be output from a buzzer or speaker.

When there is no fever event, the controller 200 determines whether the position of the patient 55 in the image is out of a predetermined range (eg, a bed). If it is out of the predetermined range, the alarm unit 220 outputs a fall event as shown in FIG. 6B (S180). At this time, as shown in FIG. 6B, even the alarm “fall event occurs” is also recorded in the storage unit 210. Optionally, a beep sound can be output from a buzzer or speaker.

Accordingly, the administrator or medical personnel can quickly take follow-up measures by looking at the alarm unit 220 exposed on the display 230. Therefore, there is an advantage of being able to monitor tens to hundreds of patients in real time with only a minimum number of personnel.

transform Example of action

As a modified embodiment of the above-described preferred embodiment, it is possible to sequentially monitor a fall event and a fever event after a bedsore event.

Optionally, after determining the fever event, the bedsore event and the fall event may be sequentially determined, or the fall event and the bedsore event may be sequentially determined.

In addition, after determining the fall event, a bed sore event and a fever event may be sequentially determined, or a fever event and a bed sore event may be sequentially determined.

Also, optionally, at least two or more of a fall event, a pressure sore event, and a fever event may be determined almost simultaneously.
