Intelligent Home Care Bed System Performing Patient Care Functions According to Schedules And Using Method for the Same}

The present invention relates to an intelligent home care bed system that executes and manages a patient care function according to a schedule and a method of using the same, and more particularly, an intelligent home care bed system that executes and manages a patient care function according to a schedule, which automatically executes posture change and massage according to a set schedule to reduce the physical and mental burden of caregivers taking care of home care recipients using an intelligent home care bed and reduces the time burden devoted to care, and provides a function to monitor the status of home care recipients from outside even when going out and methods of use thereof.

As the number of long-term care insurance grade holders increased rapidly due to rapid population aging, the number of users of electric beds increased by 1,100% in 2014 compared to 2008 (Korea Institute for Health and Social Affairs, 2017).

Community integrated care (community care) is a policy to improve housing, medical care, nursing care, and care services so that the elderly can spend a healthy old age in the place where they lived in order to relieve widespread care anxiety and improve the quality of life of the people in the face of a super-aged society.

There are four main reasons for promoting community integrated care services. First, the demand for care for the elderly is rapidly increasing due to the rapid aging of the population. Second, there are many cases of social hospitalization where people want to stay at home rather than hospitals or large facilities, but are forced to be hospitalized due to hospitals and facilities-oriented medical and welfare services. Third, the lack of services to care for the elderly at home is causing a great burden on families. Fourth, housing, health and medical care, welfare, and care services are supplied individually centering on supply institutions, and satisfaction is declining.

On the contrary to the expansion of home care, caregivers are complaining of problems related to care. Currently, the time for long-term care insurance visits is limited to a maximum of 4 hours per day according to the domestic elderly-related policy. 84% of guardians of severely ill patients felt that their daily lives had changed as they took care of them for an average of 5.6 hours/day, and 59% of the guardians of mild patients felt that their daily lives had changed (Korea Guardians' Perceptions Survey, 2020).

The daily life activities provided by the guardian for the subject of home care include waking up, washing face, eating, toilet management, changing clothes, and bathing, and providing posture change and massage to manage the subject's health. In order to manage bedsores that may occur in home care recipients, various posture changes such as side positioning and counter-sitting should be provided at least six times, including bedtime.

Although the average amount of time spent by caregivers for home care recipients is 5.6 hours per day, in practice, caregivers cannot leave the home care recipients for risk response and periodic health care.

Caregivers are complaining of problems due to difficulties in continuously providing Activity of Daily Living (ADL) such as toilet treatment, recovery, and health care to those subject to home care.

Referring to FIG. 1 , an intelligent home care bed system for executing and managing patient care functions according to a schedule of the present invention may include an intelligent home care bed 100, a system server 200, and a mobile device 300.

In the intelligent home comfort bed 100 of the present invention, the backrest angle, legboard angle, and height of a lying patient are adjusted, tilting and vibration massage functions are provided, and bio-signals and images of the patient are provided in real time. 2 is a schematic diagram of an intelligent home care bed 100 according to an embodiment of the present invention. Referring to FIG. 2, the intelligent home comfort bed 100 of the present invention includes a backrest angle adjusting unit 111, a legboard angle adjusting unit 112, a height adjusting unit 113, a tilting adjusting unit 114, a vibration massage unit 115, a function control unit 110, a pressure sensor 121, a call button 122, a sensor unit 120, an imaging device 131, and a biosignal sensor 132 , Additional devices may be configured to include a communication unit 130, a communication unit 140, a memory unit 150 and a power supply unit 160.

In the present invention, the backrest angle adjusting unit 111 can raise and lower the backrest angle of the intelligent home comfort bed 100 to a specified angle. The intelligent home care bed 100 of the present invention is a bed used by home care subjects with reduced mobility, and takes a flat position when patients lying down for a long time are in a sleeping position, and a chair position when the patient takes a sitting position. When the patient takes a chair position or needs to raise the backrest, the backrest angle adjuster 111 can raise the backrest up to 90 degrees. The climbing angle adjuster 110 may include a first driving motor (not shown) to adjust the climbing angle by the driving force of the first driving motor.

The legboard angle adjusting unit 112 of the present invention can raise and lower the legboard angle of the intelligent home comfort bed 100 to a designated angle. When it is necessary to raise or lower the patient's lower body or leg, the angle of the leg plate can be adjusted through the leg plate angle adjusting unit 110 . In addition, the leg board angle adjusting unit 112 may move in conjunction with the backrest angle adjusting unit 111 when the patient takes a chair position. The leg plate angle adjuster 110 includes a second driving motor (not shown), and the leg plate angle can be adjusted by the driving force of the second driving motor.

The tilting control unit 114 of the present invention can raise and lower the side angle of the intelligent home care bed 100 to a designated angle. Since home care recipients spend a long time lying in bed, they need to turn over or change their posture to prevent pressure sores. The tilting control unit 114 includes a fourth driving motor (not shown) and can adjust the side angle by the driving force of the fourth driving motor. Pressure sores refer to skin damage caused by deterioration of the skin, subcutaneous fat, and muscles due to a lack of oxygen and nutrient supply due to a blood circulation disorder in a body part that is constantly under pressure. Bedsores are caused by people who lie down for a long time and do not move. They occur when the skin dies and rots due to lack of oxygen due to poor blood circulation in the area where the bone protrudes. In order to prevent and treat pressure sores, the pressure applied to the affected area must be relieved. To this end, it is necessary to frequently change the posture of the patient. The tilting control unit 114 of the present invention can change the posture of the patient by operating according to the time and period set by the schedule management unit 250 or the mobile schedule management unit. In the present invention, it is possible to change the sitting position through the function of adjusting the angle of the backrest, the angle of the leg board, and the height, and it is possible to change the position of the person to be cared for by changing the tilt to the side of the bed through the tilting function.

The vibration massage unit 115 of the present invention can generate vibrations in the mattress of the intelligent home comfort bed 100 to massage the surface where the patient's body contacts the mattress. For those subject to home care, their muscles may deteriorate because they spend a long time lying in bed, so they need to strengthen their muscles. Therefore, it is necessary to apply vibration to the surface on which the patient is lying to stimulate the patient's skin to help blood circulation. Massage through vibration may be concentrated on the back, waist, buttocks, etc. of home-care subjects who are particularly likely to develop pressure ulcers. The vibration massage unit 115 of the present invention may operate according to the time and period determined by the schedule management unit 250 or the mobile schedule management unit 340 to provide vibration massage to the patient. The vibration massage unit 115 may include a fifth driving motor (not shown) to generate vibration by the driving force of the fifth driving motor or to generate vibration using a 20 Hz to 50 Hz sound wave vibration generating speaker to perform massage.

Hereinafter, a method of using the intelligent home care bed system that executes and manages the patient care function according to a schedule according to the present invention will be described with reference to the accompanying drawings. 6 is a flowchart of a method of using an intelligent home care bed system that executes and manages a patient care function according to a schedule according to an embodiment of the present invention. Referring to FIG. 6 , the method of using the intelligent home care bed system that executes and manages patient care functions according to a schedule according to the present invention may include the following 7 steps.

Step 1 (S10): Step of logging in from the mobile device 300

Step 2 (S20): Setting an execution schedule for functions of the intelligent home care bed (100)

Third Step (S30): Storing the schedule information set in the second step (S20) in the data storage unit 220 of the system server 200.

Fourth Step (S40): Transmitting the schedule information stored in the third step (S30) to the intelligent home care bed (100)

Fifth step (S50): Executing the functions of the intelligent home care bed 100 according to the stored schedule

6th Step (S60): Transmitting information on the function executed in the 5th step (S50) to the system server 200

Step 7 (S70): Inquiring function execution information of the intelligent home care bed 100 in the system server 200 or the mobile device 300

Here, the login in the mobile device of the first step (S10) is performed by installing a dedicated app in the Android or IOS environment and logging in by running the installed app, and in the PC environment of the Windows OS environment such as a desktop or laptop, login means logging in by connecting the url for system use in a web browser.

The second step (S20) is to set the execution schedule for the functions of the intelligent home care bed. For each function of the backrest angle, legboard angle, tilting, and vibration massage, execution reservations can be made for each time slot, and each function must be individually scheduled without duplication. In addition, in the case of tilting, it is necessary to perform the positioning and posture conversion function to prevent pressure sores at least 6 times a day at intervals of 2 hours, and it is recommended to register a schedule for vibration massage to be performed once a day.

The third step (S30) is a step of storing the schedule information set in the second step (S20) in the data storage unit 220 of the system server 200, and the execution schedule information for each function set in the second step (S20) is transmitted to the system server 200, and then the set content can be inquired and modified at any time.

In the fourth step (S40), the stored schedule information is transmitted to the intelligent home care bed 100, and the schedule information is stored in the memory unit 150 of the intelligent home care bed 100. In addition, the guardian can receive the schedule information stored in the intelligent home care bed 100 and compare it with the information stored in the system server 200.

The fifth step (S50) executes the function of the intelligent home care bed 100 according to the stored schedule. At this time, the intelligent home care bed 100 executes the function of the scheduled schedule and transmits function execution information to the system server 200 if there is a person to be cared for in the intelligent home care bed 100 as a result of sensing by the pressure sensor 121 prior to executing the function according to the schedule. However, when the data of the pressure sensor 121 is checked and the pressure data value is low, it is determined that there is no person to be cared for in the intelligent home care bed 100, and function execution is suspended and an alarm is transmitted to the system server 200. The system server 200 records all information and transmits an alarm to the mobile device 200 of the guardian. After confirming the alarm, the guardian can cancel or restart the schedule function after appropriate confirmation and action. The guardian can set the function not to be executed when there is a schedule in a specific time zone apart from the schedule setting when a situation in which the patient needs to get out of bed occurs according to a specific situation.

The sixth step (S60) transmits information on the executed function to the system server 200. When the function of the intelligent home care bed 100 is completed according to the schedule, the completed information is transmitted to the system server 200.

The seventh step (S70) is to inquire function execution information from the system server 200 or the mobile device 300, and the inquiry can be performed by using the mobile device 300 or a computer under an Internet-enabled environment. Information on the schedule and function execution results according to the schedule can be inquired.

Here, the call button 122 is pressed as needed by the patient regardless of the schedule to send an alarm to the guardian, and the biosignal sensor 132 regularly transmits sensing information to the system server 200 without manipulation by anyone.

The present invention is not limited to the above embodiments, but can be manufactured in a variety of different forms, and those skilled in the art to which the present invention pertains do not change the technical spirit or essential features of the present invention. It will be understood that it can be implemented in other specific forms. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting.
