Description

Nursing system, nursing device, nursing method and computer program product

Technical Field

The present invention relates to a nursing system, and more particularly, to a nursing system, a nursing device, a nursing method, and a nursing program, which are less susceptible to personal differences and the like, and which enable a nursing person to easily grasp the tendency of the body temperature of a nursing target to change.

Background

In a place where infants or preschool children (hereinafter, referred to as preschool children) in a nursery garden or a nursery school live collectively, since the immunity of infants is on the way of being constructed, fever such as cold frequently occurs, and (collective) infection such as influenza or viral gastroenteritis is likely to occur. Therefore, in order to detect a change in physical condition of a preschool child or the like at an early stage, the care giver needs to perform body temperature measurement at any time when necessary, while observing the state of the preschool child or the like in addition to regular body temperature measurement several times a day during the care.

In order to prevent sudden death (SIDS) caused by sleeping on her stomach, the state of a 0-year-old infant is confirmed at least every 5 minutes during the afternoon nap in accordance with the guidelines of the national or local government. This job is usually entered into a sheet record table, and the record has an obligation stored therein.

Due to the recent increase in the need for nursing care and the shortage of nursing care providers, there is a problem that the rate of monitoring the physical condition of a preschool child or the like and the state of afternoon nap during the work of the nursing care providers increases, and the burden increases.

In view of the above, there is disclosed a technique of identifying a child (infant) by performing image processing on imaging data of the child captured by a camera, measuring biological information such as respiration, pulse, body movement, and body temperature of the identified child, and notifying the child when abnormality of the biological information is detected (see patent document 1).

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Hereinafter, an embodiment of a nursing system embodying the present invention will be described.

Embodiments of the present invention will be described with reference to the drawings. A nursing system 10 according to an embodiment of the present invention shown in fig. 1 is configured by a sensor unit 20 (detection unit) attached to clothes 13 or the like of a nursing subject a, a tablet terminal 30 (nursing device) carried by a caregiver B, and a server 40.

In the present embodiment, the care system 10 is applied to an care garden, and the care subjects a are preschool children, and the caregivers B are care givers. For convenience of explanation, fig. 1 shows only one person as a care subject a and a care subject B, but the following description will be made as to a case where a plurality of care subjects a and a plurality of care subjects B, which are not shown, are present.

The sensor unit 20 is worn on the garment 13 worn by the subject a, and has a function of detecting information related to the health state of the subject a.

The sensor unit 20 has a rectangular parallelepiped shape with a small thickness, and a surface on the front side of the body becomes a rear surface when worn on the care subject a. The sensor unit 20 includes a power status indicator lamp, a communication status indicator lamp, and a charging status indicator lamp on the front surface, a power button, a power status indicator lamp, and a snap fastener on the back surface, and an input/output terminal on one side surface. The sensor unit 20 includes a battery therein. The sensor unit 20 is of such a size and weight that the clothing 13 worn on the care subject a does not interfere with or bear the care subject a.

The clothing 13 is also provided with snap fasteners corresponding to the snap fasteners of the sensor unit 20. That is, the snap of the sensor unit 20 and the snap of the clothing 13 can be engaged by having a convex portion on one side and a concave portion on the other side. These snap fasteners preferably have high electrical and thermal conductivity and are made of, for example, metal. This allows the temperature sensor 21 and the heart rate measuring sensor 23 to be measurement terminals, which will be described later.

As shown in fig. 2, the sensor unit 20 includes a temperature sensor 21, and is capable of detecting information on the body surface temperature of the care target a. The sensor unit 20 includes an acceleration sensor 22 and a heart rate measurement sensor 23, and can detect information on the posture and heart rate of the body of the care subject a. Note that the acceleration sensor 22 may be replaced with a gyro sensor.

The sensor unit 20 includes a communication unit 24, and has a function of transmitting and receiving detection information from various sensors of the sensor unit 20, status information of the sensor unit 20 itself, and the like to and from the tablet terminal 30 via wireless communication such as Bluetooth (registered trademark) or Wi-Fi. Specifically, the sensor unit 20 transmits data to the tablet terminal 30 at predetermined intervals of approximately 1 second to several seconds. As described above, the sensor unit 20 may be provided with an input/output terminal to which a USB cable or the like is connected to perform wired communication or battery charging.

The sensor unit 20 is given a unique identifier for each subject a, and associates one subject a with another. The association of the care subject a with the sensor unit 20 can be edited by the tablet terminal 30. The information on the body surface temperature, the information on the posture, and the information on the heart rate of the care subject a detected by the sensor unit 20 are transmitted to the tablet terminal 30 as data including the identifier. Thus, the tablet terminal 30 or the server 40 can manage or control information for each care recipient a.

The sensor unit 20 includes a storage unit 25. Accordingly, even when the communication between the sensor unit 20 and the tablet terminal 30 is interrupted or interrupted due to a deterioration in the communication state, or when data collision occurs and information detected by the sensor unit 20 cannot be transmitted to the tablet terminal 30, the detected information can be stored in the internal storage unit 25 in advance, and the information can be retransmitted from the time of recovery from the communication state, and the lack of information and the like can be avoided.

The garment 13 on which the sensor unit 20 is worn is a underwear for the subject a or a garment worn on the underwear. Specifically, a holder portion having a snap fastener and capable of accommodating the sensor unit 20 is formed on the garment 13, and the snap fastener of the sensor unit 20 is engaged with the snap fastener, whereby the sensor unit 20 is attached to the garment 13. By using conductive fibers for the cloth on the body surface side of the support portion of the garment 13, even if the sensor unit 20 does not directly contact the body surface of the care target a, the potential of the body surface can be detected, and the body surface temperature of the care target a can be detected via the conductive fibers.

Next, referring to fig. 2, the tablet terminal 30 will be explained.

The tablet terminal 30 is used for storing the state of the care subject a grasped by the caregiver B or for performing a required examination, and may be a generally commercially available configuration. The size and weight of the caregiver B are preferable, and the size is preferably a size of a notebook for visibility and operability, but may be a smaller size such as a smartphone or may be a large size and non-portable structure such as a Personal Computer (PC).

Specifically, the tablet terminal 30 of the present embodiment includes a storage unit 31 that stores information acquired from the sensor unit 20 or the server 40, an arithmetic processing unit 32 that performs arithmetic processing on the information, a display unit 33 that can display various information, an audio input/output unit 36 that generates or acquires audio information, an input unit 34 that accepts input operations, and a communication unit 35 that communicates with external devices such as the sensor unit 20, the server 40, and the printer 60. The display unit 33 and the input unit 34 may be integrated as a so-called touch panel. The functions of a part of the nursing system 10 of the present embodiment are installed in the tablet terminal 30 as a program (application) and executed by the arithmetic processing unit 32.

The storage unit 31 of the tablet terminal 30 is mounted by a memory or the like built in the tablet terminal 30, and has a function of storing information detected by the temperature sensor 21, the acceleration sensor 22, and the heartbeat count measuring sensor 23 of the sensor unit 20.

The arithmetic processing unit 32 of the tablet terminal 30 is mounted on a CPU or the like incorporated in the tablet terminal 30, and calculates the body surface temperature of the care subject a based on information on the body surface temperature of the care subject a and the like.

More specifically, the arithmetic processing unit 32 sets a reference time immediately after the clothing 13 worn by the care subject a in a state where the sensor unit 20 is powered on, and sets a body surface temperature at the reference time as the reference value Ts. More specifically, the body surface temperature of the care target a is detected after the power is turned on, and the body surface temperature in the equilibrium state becomes the reference value Ts with the reference time point being the time point when the body surface temperature becomes the equilibrium state for a certain time. The reference time is not limited to this time, and for example, the body surface temperature in the equilibrium state may be modified to the reference value Ts by setting a time when the body surface temperature is in the equilibrium state again for a certain period of time as the reference time by performing a reset operation of the reference value Ts using the tablet terminal 30.

The arithmetic processing unit 32 of the tablet terminal 30 causes the display unit 33 to display the state of the care subject a based on the reference value Ts and the body surface temperature Tn detected at any time after the reference time. Specifically, the content displayed in the following procedure is determined.

First, the difference Δ T between the reference value Ts and the latest body surface temperature Tn is calculated and obtained by the following expression 1.

Δ T-Tn-Ts … formula 1

Next, a comparison of the difference Δ T with a predetermined threshold value is performed. In the present embodiment, the first threshold T1 (e.g., 0.2 ℃), the second threshold T2 (e.g., -0.2 ℃), and the third threshold T3 (e.g., 1.0 ℃) are set as the thresholds, and the thresholds are in a relationship of T2 (negative value) < T1 (positive value) < T3 (positive value).

Specifically, when the difference Δ T is larger than the first threshold value T1, that is, T1< Δ T, the tendency of the body surface temperature is determined to be "increased" with respect to the reference value Ts, and an upward arrow "×" is displayed in the items of the body surface temperature on the display unit 33 of the tablet terminal 30.

When the difference Δ T is equal to or greater than the second threshold value T2 and equal to or less than the first threshold value T1, that is, when T2 ≦ Δ T ≦ T1, the tendency of the body surface temperature is determined to be "maintained" compared to the reference value Ts, and a rightward arrow "→" is displayed on the display unit 33.

When the difference Δ T is smaller than the second threshold value T2, that is, Δ T < T2, the tendency of the body surface temperature is determined to be "lower" than the reference value Ts, and a downward arrow "↓" is displayed on the display unit 33.

When the difference Δ T is greater than the first threshold value T1 and is greater than the third threshold value T3, that is, when T3< Δ T, it is determined that there is an abnormal temperature rise, and an alarm display for notifying that there is an abnormality in the physical condition of the care subject a is displayed on the display unit 33 of the tablet terminal 30. The notification of the abnormality may be not only the display of the abnormality on the display unit 33 but also the notification by the voice of the voice input/output unit 36.

The arithmetic processing unit 32 calculates the posture and the heart rate of the care subject a based on the information detected by the sensor unit 20 (the acceleration sensor 22 and the heart rate measurement sensor 23) and displays the posture and the heart rate on the display unit 33. The arithmetic processing unit 32 can calculate the state of tension using the information of the body surface temperature, the posture, and the heart rate, and display the state of tension on the display unit 33. The state of the care subject a is determined based on at least one of these, and when the determination result is out of the normal range, a display indicating an abnormality can be displayed on the display unit 33 of the tablet terminal 30.

Specifically, the arithmetic processing unit 32 draws attention of the care giver B by displaying an alarm when it is determined that the care giver a is lying on the front and sleepy in the posture monitoring. When the care recipient B changes the posture of the care recipient a from the posture in which the care recipient a sleeps on the front side to the normal posture and detects that the posture is changed by the acceleration sensor 22, the alarm display is released and the posture correction display (symbol or the like) of the posture change is automatically displayed on the display unit 33. The arithmetic processing unit 32 stores, in the storage unit 31, a display history concerning the posture of the care subject a within a predetermined time period before and after the posture correction display time, in order to keep a record of lying on the back.

The arithmetic processing unit 32 calculates a standard model of an individual person by performing statistical analysis for each of the care subjects a based on the heart rate detected by the heart rate measuring sensor 23 in relation to the monitoring of the heart rate, and displays an alarm when the result of monitoring the transition from the abnormal value of the standard model exceeds a predetermined threshold. The standard model of the individual based on this statistical analysis may use, for example, the mean of heart beat number, standard deviation, heart beat related LF and HF values, etc.

The arithmetic processing unit 32 may manage information such as the body surface temperature, the posture, and the heart rate for each care-target a using the identifier of the sensor unit 20. Further, the identifier associated with the care subject a may be assigned to a predetermined group defined by, for example, a group name to which the identifier belongs, the caregiver B, or the like, and the identifier may be managed or displayed on the display unit 33 on a group-by-group basis.

The arithmetic processing unit 32 has a plurality of modes with respect to the activity status indicating the activity state of the care subject a, and can switch the display items and the display contents on the display unit 33 according to each mode. Specifically, the activity state of the care subject a is classified into modes such as nap, changing clothes, swimming, going out for play, monitoring, and leaving school. For example, the arithmetic processing unit 32 may perform management such that the posture is not displayed when the activity status of the care subject a is in the monitoring mode, and the posture information is displayed when the activity status of the care subject a is in the nap mode.

The arithmetic processing unit 32 may have a function of notifying that an item to be stored, such as a body temperature or a state during a nap, is not input even when a predetermined time has elapsed. Note that the measurement of the body temperature different from the body surface temperature by the sensor unit 20 is periodically checked, and the body temperature measurement is performed by a thermometer, and a specific numerical value is input by the tablet terminal 30.

The arithmetic processing unit 32 may output information stored in the storage unit 31 of the tablet terminal 30 or information stored in the server 40 to the printer 60 of fig. 1 in a predetermined format.

The display unit 33 of the tablet terminal 30 has a function of displaying the state of the care subject a based on the body surface temperature of the care subject a by using symbols such as arrow display, characters, patterns, animation, colors, and the like.

Next, the server 40 shown in fig. 2 is explained.

The server 40 includes a database 41, an arithmetic processing unit 42, and a communication unit 43, and has a function of acquiring information on the body surface temperature, posture information, and information on the heart rate of the care subject a detected by the sensor unit 20 of the care system 10 via the tablet terminal 30, and performing a unified management, statistical processing, highly complicated analysis and calculation, and the like. The server 40 may be provided in the same facility that can communicate with the sensor unit 20 or the tablet terminal 30, or may be provided outside the facility or in the cloud to communicate via the internet or the like.

The server 40 also stores personal information such as the name, address, protector name, protector contact method, and home care garden name of the care recipient a in the database 41. The arithmetic processing unit 42 of the server 40 may also transmit data such as the body surface temperature, posture information, heart rate of the care subject a stored in the database 41 to an information terminal held by a caregiver of the care subject a via the communication unit 43. In the case of distributing the data to the guardian, information to be registered is arbitrarily input for each caregiver a and for each class, such as a contact item from the care center to which the caregiver a belongs to the guardian, and the like, is also distributed at the same time.

Fig. 3 shows a flowchart showing a routine for monitoring the body surface temperature of the care subject a executed by the tablet terminal 30, and the following description will be made based on this flowchart. The routine is started in a state where the sensor unit 20 is worn on the care subject a, the power supply is turned on, and the communication connection with the tablet terminal 30 is established.

First, in step S1, the arithmetic processing unit 32 of the tablet terminal 30 acquires information on the body surface temperature of the care subject a detected by the sensor unit 20, calculates the body surface temperature (detection information acquisition step), and determines whether or not the body surface temperature is in an equilibrium state. If the determination result is true (YES), the process proceeds to step S2. On the other hand, if the determination result is false (NO), step S1 is repeated.

In step S2, the arithmetic processing unit 32 of the tablet terminal 30 sets the body surface temperature of the care subject a when the determination of true (Yes) is made in step S1 as the reference value Ts (reference value setting step).

In step S3, the arithmetic processing unit 32 of the tablet terminal 30 determines whether or not the difference Δ T obtained by subtracting the reference value Ts from the latest body surface temperature Tn detected by the sensor unit 20 (difference calculation step) is greater than the first threshold value T1 (temperature increase determination). If the determination result is false (NO), that is, if the difference Δ T is equal to or greater than the first threshold value T1, the routine proceeds to step S4.

In step S4, the arithmetic processing unit 32 determines whether the difference Δ T is smaller than the second threshold T2 (temperature decrease determination). If the determination result is true (YES), that is, if the difference Δ T is smaller than the second threshold value T2, the routine proceeds to step S5.

In step S5, the arithmetic processing unit 32 assumes that the state of the body surface temperature of the corresponding care target a tends to be maintained, displays a rightward arrow (→) on the display unit 33 (display step), and proceeds to step S11.

On the other hand, if the determination result at step S4 is false (No), that is, if the difference Δ T is smaller than the second threshold value T2, the process proceeds to step S6.

In step S6, the arithmetic processing unit 32 displays the downward arrow (↓) on the display unit 33 assuming that the state of the body surface temperature of the corresponding care target a is in the descending tendency (display step), and the process proceeds to step S11.

If the determination result at step S3 is true (Yes), that is, if the difference Δ T is smaller than the first threshold value T1, the routine proceeds to step S7.

In step S7, the arithmetic processing unit 32 displays the upward arrow (×) on the display unit 33 assuming that the state of the body surface temperature of the corresponding care subject a is in the upward tendency with respect to the tablet terminal 30 (display step), and the process proceeds to step S8.

In step S8, the arithmetic processing unit 32 determines whether or not the difference Δ T is greater than a third threshold value T3 (abnormal temperature determination). If the determination result is true (YES), that is, if the difference Δ T is greater than the third threshold value T3, the routine proceeds to step S9. On the other hand, if the determination result is false (NO), the process proceeds to step S11.

In step S10, the arithmetic processing unit 32 causes the display unit 33 to display an alarm, and the process advances to step S10.

In step S10, the arithmetic processing unit 32 determines whether or not an operation to reset the alarm display has been accepted at the input unit 34. If the determination result is true (YES), that is, if an operation to reset the alarm is received from the caregiver B, the routine proceeds to step S11. On the other hand, if the determination result is false (NO), that is, if there is NO operation to reset the alarm, step S10 is repeated.

Next, in step S11, the arithmetic processing unit 32 determines whether or not a monitoring end condition of the care target a based on the body surface temperature is satisfied. As the monitoring end condition, there are, for example, power-off of the sensor unit 20 or the tablet terminal 30, a reset operation to the reference value Ts of the tablet terminal 30, and the like. If the determination result is false (No), that is, if the monitoring end condition is not satisfied, the process returns to step S3 to repeat the determination of the change in the body surface temperature.

On the other hand, if the determination result is true (Yes), that is, if the power supply of the sensor unit 20 or the tablet terminal 30 is turned off or a reset operation to the reference value Ts of the tablet terminal 30 is performed, the routine is ended.

Such a body surface temperature monitoring routine is executed for each care subject a, and the body surface temperature trend of each care subject a is displayed on the display unit 33 of the tablet terminal 30 as needed.

Fig. 4 shows an example of display of the display unit 33 of the tablet terminal 30 at the time of monitoring a subject, and fig. 5 shows an example of display of the display unit 33 of the tablet terminal 30 at the time of alarm.

When the power supply is turned on, the sensor unit 20 starts transmission of state information of the sensor unit 20 itself, such as detection information from various built-in sensors and remaining battery level information. At this time, the tablet terminal 30 receives information from the sensor unit 20 and confirms the connection with the sensor unit 20. Since the sensor unit 20 is uniquely associated with the care subjects a, the states of the care subjects a are listed as shown in fig. 4.

Specifically, in fig. 4, a kindergarten child information column 51, a kindergarten child status column 52, and an examination body temperature information column 53 are displayed in a horizontal array for 5 subjects a.

In the child information column 51, information on the photographs of the faces of the nursing subjects a1 to a5, the classes to which the nursing subjects belong, the names, the identification numbers, the battery states of the sensor units 20, and the current activity states are displayed.

The child status column 52 displays the current status of the care subjects a1 to a5 calculated by the arithmetic processing unit 32 based on the detection information from the sensor unit 20, and displays the posture status column 52a, the tension status column 52b, the heart rate column 52c, and the body surface temperature gradient column 52d from the left side. Specifically, the posture state column 52a displays the postures (lying on the back and lying on the front) of the care subjects a2 and a4 during the nap. In the tension column 52b, "attention" is displayed to the care subject a5 with a high tension. The heart rate rows 52c display the heart rate of the care subjects a1 to a 5. In the body surface temperature gradient column 52d, the body surface temperature trends of the subjects a1 to a5 are displayed as arrows in accordance with the body surface temperature monitoring routine of fig. 3.

The examination body temperature information column 53 displays the examination body temperature time and the body temperature as a result of the examination body temperature.

Further, an alarm bar 54 is displayed on the upper part of the screen of the display unit 33. The alarm column 54 displays information on the care subjects a who are in the abnormal state in the child status in kindergarten column 52.

In particular, when the body surface temperature is determined to be an abnormal temperature (YES in step S8), an alarm indicating that the body surface temperature has abnormally increased is displayed in a pop-up manner as shown in fig. 5. In this case, "note input" enabling text input, "alarm pause" button temporarily stopping the alarm, "security confirmation" button enabling the security of the alarm object to be confirmed and the alarm to be reset, and "emergency contact" button enabling contact to the emergency contact method are displayed on the lower part of the screen.

Similarly to the monitoring of the body surface temperature, the arithmetic processing unit 32 can display an alarm based on a pop-up when a sleeping state on the front is detected by the monitoring of the posture or an abnormal heartbeat is detected by the monitoring of the heartbeat.

The tablet terminal 30 communicates with the server 40 at predetermined time intervals, and information acquired from the sensor unit 20, the calculation result of the calculation processing unit 32 of the tablet terminal 30, a communication log, an alarm log, and the like are stored in the database 41 of the server 40 in advance.

As described above, in the nursing system 10, the sensor unit 20 detects information on the body surface temperature of the object a to be cared, the tablet terminal 30 sets the body surface temperature at the reference time point to the reference value Ts, calculates the difference Δ T from the body surface temperature Tn detected after the reference time point, and displays a display corresponding to the difference Δ T on the display unit 33 as the state of the object a to be cared.

Separately from the body temperature examination using the thermometer necessary for the operation of the caregiver B, the body surface temperature is detected at any time from the sensor unit 20 that can be worn on the clothing 13 of the care subject a, and the temperature change from the reference value is displayed, whereby the caregiver a can easily grasp the change in the temperature state of the care subject a without taking much labor and time.

In particular, the reference value Ts of the body surface temperature is set to the body surface temperature at the time when the sensor unit 20 is worn close to the body surface of the care subject a and is in a balanced state, whereby the monitoring of the body surface temperature of the care subject a can be started without taking the labor and time set by the care person B. Further, by monitoring the change with reference to the time when the sensor unit 20 is worn close to the body surface of the care target a, it is less likely to be affected by personal differences, seasonal variations, environmental variations, periodic variations due to the biological clock of one day, and the like, and unnecessary attention to the caregiver B can be reduced.

Further, by switching the display corresponding to the difference Δ T between the reference value Ts and the body surface temperature Tn based on a predetermined range constituted by the first threshold value T1 and the second threshold value T2, the temperature tendency of the body surface temperature can be easily expressed. As shown in fig. 4, by representing the display corresponding to the difference Δ T by an arrow, the caregiver B can easily visually recognize the display at a glance and can intuitively grasp the change in the body surface temperature of the care target a.

When the difference Δ T between the reference value Ts and the body surface temperature Tn exceeds the third threshold T3 higher than the first threshold T1, the abnormality of the care subject a can be appropriately notified to the care giver B by displaying an alarm on the display unit 33 as shown in fig. 5.

In addition to the body surface temperature, the posture or the heart rate of the care target a is detected by the sensor unit 20, and the posture or the heart rate is displayed as the state of the care target a (the kindergarten child state) as shown in fig. 4, whereby the caregiver B can grasp the state of the care target a in more detail and easily.

Further, the alarm display is displayed on the display unit 33 when the posture of the care subject a is changed to the lying-on sleeping state, and when the posture is changed from the lying-on sleeping state to the normal posture, the alarm display is released, and the posture correction display indicating that the posture is changed is displayed on the display unit 33, whereby the caregiver B can relieve the lying-on sleeping of the care subject a in advance without requiring the operation of the tablet terminal 30, and sudden death (SIDS) due to the lying-on sleeping or the like can be prevented.

When the heart rate state of the care subject a is in an abnormal state, the alarm display is displayed on the display unit 33, whereby the caregiver B can recognize that the heart rate of the care subject a is abnormal.

Further, information (body surface temperature, posture, heart rate) detected by the sensor unit 20 may be distributed to an information terminal held by a caregiver or the like who cares the subject a, and thus, not only the caregiver B but also the caregiver or the related person who cares the subject a can easily share information on the subject a.

Thus, according to the nursing system 10 of the present embodiment, it is difficult for the caregiver B to grasp the change in the state of the care target a due to the influence of personal differences or the like.

The description of the embodiments of the present invention is completed as described above, but the embodiments of the present invention are not limited to the embodiments.

For example, although the care system 10 is applied to an care garden in the above embodiment, the application target of the present invention is not limited to a care garden for preschool children. For example, the subject to be cared for may be an infant, a student, or the like, and the applicable organization may be applied to other facilities such as a nursery garden, a school, and a hospital.
