The present invention relates to a measuring device and a measuring system.
In hospitals and the like, urine bags are used for patients having difficulty in urinating by themselves after surgery with general anesthesia, or the like. A urine bag stores urine discharged from a patient. A measuring device measuring a urinary output stored in this urine bag is known (for example, refer to Patent Literature 1). In the measuring device, a urinary output is measured, and a display unit displays the measured urinary output.
In measuring devices in the related art, a urinary output is displayed in a display unit. For this reason, a staff member of a hospital, such as a nurse, regularly visits a hospital room, checks a urinary output displayed in the display unit, discharges urine from a urine bag to a graduated cylinder, and weighs the urine, thereby recording the amount of urine in a management sheet or the like. Accordingly, for example, the physical condition or the like of a patient after surgery is managed, or timings of taking urine from a urine bag are adjusted or the like. There is a need for a staff member to regularly visit a hospital room to perform work of checking a urine bag, and a burden may be placed on a staff member. Particularly, during work of checking at night having fewer staff members and being work performed in the darkness, a burden on a staff member increases.
A measuring device is normally attached to a bed. For example, when a patient temporarily moves from a bed, a measuring device needs to move in accordance with movement of the patient. In this case, work of securing a power source outlet at a destination and attaching a power source adapter or the like for supplying power to the measuring device occurs.
An object of an aspect of the present invention is to provide a measuring device and a measuring system capable of achieving reduction of a burden.
According to an aspect of the present invention, there is provided a measuring device acquiring information related to urine stored in a urine bag. The measuring device includes a weighing unit configured to measure a mass value of the urine bag; a calculation unit configured to calculate at least one of a voided volume and a urinary output per unit time on the basis of the mass value weighed by the weighing unit; a transmission unit configured to transmit urinary output information related to at least one of the voided volume and the urinary output per unit time calculated by the calculation unit; and a first battery configured to supply power to the weighing unit, the calculation unit, and the transmission unit.
In the measuring device according to the aspect of the present invention, at least one of the voided volume and the urinary output per unit time is calculated, and urinary output information is transmitted. Accordingly, for example, a different terminal can acquire urinary output information by receiving the urinary output information. In this manner, in the measuring device, even if a staff member does not visit a hospital room, the voided volume or the like can be checked on the basis of urinary output information in the different terminal. Therefore, there is no need for a staff member to perform work of visual checking. For this reason, in the measuring device, reduction of a burden on a staff member can be achieved. In addition, it is possible to reduce a burden on a staff member performing checking at night, that is, performing work in the darkness with less manpower.
The measuring device includes the first battery supplying power to the weighing unit, the calculation unit, and the transmission unit. For this reason, in the measuring device, for example, when a patient temporarily moves, each unit can be driven even if a power source outlet is not secured. Therefore, a burden on a staff member can be reduced. In addition, in the measuring device, power can be supplied to each unit while the measuring device is moving or the like. Therefore, in the measuring device, urinary output information can be transmitted even while the measuring device is moving or the like.
According to the embodiment, the measuring device may further include a display unit configured to be able to display the urinary output information, a control unit configured to control contents of display of the display unit, and an acquisition unit configured to acquire a state of the first battery. The control unit may cause the display unit to display the state of the first battery acquired by the acquisition unit. In this configuration, the state (residual quantity or the like) of the first battery can be checked in the display unit.
According to the embodiment, the control unit may cause the display unit to display that a residual quantity of the first battery has decreased when the residual quantity becomes equal to or smaller than a threshold. In this configuration, when the residual quantity of the first battery has decreased, it is possible to notify that the first battery needs to be charged.
According to the embodiment, the measuring device may further include a determination unit configured to determine anuria, oliguria, and polyuria on the basis of the urinary output information and a threshold set in advance. The transmission unit may transmit notification information when the determination unit determines anuria, oliguria, or polyuria. In this configuration, a staff member can be notified of anuria, oliguria, or polyuria. In addition, since the measuring device includes a battery, notification information can be transmitted even while the measuring device is moving or the like.
According to the embodiment, the measuring device may further include a second battery configured to supply at least power for memory back-up when power is not supplied from the first battery. In this configuration, even when power is not supplied from a power source unit and the first battery, setting and the like in the measuring device, such as setting of a timepiece, measurement results, and measurement history can be maintained by the second battery.
According to another aspect of the present invention, there is provided a measuring system including the measuring device described above, and a management device configured to acquire information related to urine acquired by the measuring device.
In the measuring system according to the aspect of the present invention, the measuring device calculates at least one of the voided volume and the urinary output per unit time and transmits urinary output information. Accordingly, the management device can acquire urinary output information by receiving the urinary output information. In this manner, in the measuring system, even if a staff member does not visit a hospital room, the voided volume or the like can be checked on the basis of urinary output information in the management device. Therefore, there is no need for a staff member to perform work of visual checking. For this reason, in the measuring system, reduction of a burden on a staff member can be achieved. In addition, it is possible to reduce a burden on a staff member performing checking at night, that is, performing work in the darkness with less manpower.
The measuring device includes a battery supplying power to the weighing unit, the calculation unit, and the transmission unit when power is not supplied from the power source unit. For this reason, in the measuring device, for example, when a patient temporarily moves, each unit can be driven even if a power source outlet is not secured. Therefore, a burden on a staff member can be reduced. In addition, in the measuring device, power can be supplied to each unit while the measuring device is moving or the like. Therefore, in the measuring system, even while the measuring device is moving or the like, urinary output information can be transmitted and urinary output information can be acquired in the management device.
According to the aspects of the present invention, reduction of a burden can be achieved.

In the setting screen, communication according to any of the standards of IEEE802.11b/g/n/a (2.4 GHz/5 GHz) can be set.
The control unit 14 inputs patient information output from the barcode reader BR and registers the patient information. When a predetermined operation is performed by an operator for the item “patient/user registration” in the setting screen D2, the control unit 14 causes the barcode reader BR to start reading. When patient information output from the barcode reader BR is received, the control unit 14 manages the patient information and urinary output information (which will be described below) in association with each other.
The control unit 14 calculates a voided volume and a urinary output per unit time on the basis of the mass value weighed by the weighing unit 12. The control unit 14 calculates a weight from weighing data output from the converter 26 and calculates the weight (voided volume) [g] of urine by subtracting a tare weight (a weight including the urine bag 100 and the like) from the weight. A control unit 54 stores urinary output information indicating the calculated weight of urine in the HDD or the like. The control unit 14 calculates a urinary output [g] per unit time on the basis of the calculated weight of urine. The control unit 14 calculates a urinary output per unit time (1 hour or 1 day) in accordance with contents of setting. The control unit 14 stores the calculated urinary output per unit time in the HDD or the like.
The control unit 14 causes the touch panel display 16 to display the voided volume and the urinary output per unit time. As illustrated in

The control unit 14 determines anuria, oliguria, or polyuria on the basis of a urinary output per unit time. The control unit 14 determines anuria, oliguria, or polyuria on the basis of parameters set regarding anuria, oliguria, and polyuria set in advance. When the control unit 14 determines anuria, oliguria, or polyuria, the control unit 14 outputs notification information for causing the touch panel display 16 to display anuria, oliguria, or polyuria to the touch panel display 16. As illustrated in
The control unit 14 acquires the state of the first battery 22. The control unit 14 acquires the residual quantity of the first battery 22. The control unit 14 controls display of the residual quantity icon A1 displayed in the touch panel display 16 in accordance with the residual quantity of the first battery 22. When the residual quantity of the first battery 22 becomes equal to or smaller than the threshold, the control unit 14 causes the touch panel display 16 to display that the residual quantity has decreased. As illustrated in
The control unit 14 outputs urinary output information to the communication unit 18. A timing when the control unit 14 outputs urinary output information to the communication unit 18 may be a timing when urinary output information is calculated or may be a predetermined time interval. The control unit 14 causes the communication unit 18 to transmit urinary output information.
The touch panel display 16 can display texts, images, or the like and receives an input of an operator. In the present embodiment, the touch panel display 16 can perform display in colors (256 or more colors). Contents of display in the touch panel display 16 can be controlled by the control unit 14.
The communication unit 18 is a wireless LAN module for wirelessly transmitting urinary output information. When urinary output information is output from the control unit 14, the communication unit 18 wirelessly transmits urinary output information in association with a unique identification code of the measuring device 3. Regarding a communication method of the communication unit 18, various kinds of known wireless communication methods (IEEE802.11b/g/n/a) can be utilized. When notification information is output from the control unit 14, the communication unit 18 transmits notification information to the management device 5.
The power source unit 20 supplies power to each unit of the measuring device 3. Specifically, the power source unit 20 supplies power to the weighing unit 12, the control unit 14, the touch panel display 16, and the first battery 22. The power source unit 20 receives supply of power from the power source outlet PO via the power source cord PC.
When power is not supplied from the power source unit 20, the first battery 22 supplies power to the weighing unit 12, the control unit 14, and the touch panel display 16. For example, the first battery 22 is a lithium-ion battery. The first battery 22 is charged upon reception of supply of power from the power source unit 20. The first battery 22 is charged by a charging device (not illustrated) connected to the power source unit 20. When power is no longer supplied from the power source unit 20, the first battery 22 starts supply of power. The first battery 22 may be attachable/detachable with respect to the housing 10. In this case, the first battery 22 can be charged by a charger provided in a nurse station or the like.
The second battery 23 supplies power for memory back-up. For example, the second battery 23 is a lithium-ion battery. The second battery 23 may have a smaller capacity than the first battery 22. When power is not supplied from the power source unit 20 and the first battery 22 is detached from the housing 10 or when the residual quantity of the first battery 22 has decreased, the second battery 23 supplies power to at least the control unit 14. The second battery 23 is charged upon reception of supply of power from the power source unit 20.
The management device 5 functions as a host device integrally managing the measuring device 3. The management device 5 manages data measured by the measuring device 3.

The communication unit 50 is a wireless LAN module for wirelessly receiving urinary output information. The communication unit 50 outputs received urinary output information and an identification code to the storage unit 52.
The storage unit 52 is configured to have a ROM, a RAM, an HDD, and the like. The storage unit 52 stores urinary output information received by the communication unit 50 in association with patient information.
The control unit 54 is configured to have a CPU and the like. For example, the control unit 54 controls display of the display unit 56 in accordance with an operation of an operation unit (not illustrated) such as a keyboard. For example, the display unit 56 is a display of a computer. For example, when an operation of requiring display of urinary output patient information is received, the control unit 54 acquires urinary output information from the storage unit 52 and causes the display unit 56 to display the acquired urinary output information.
As illustrated in
The control unit 54 may receive an input of patient information and may transmit patient information to the measuring device 3. In this configuration, the measuring device 3 may receive patient information transmitted from the management device 5 using the communication unit 18 and may register the patient information. In addition, when patient information read by the barcode reader BR coincides with patient information transmitted from the management device 5, the measuring device 3 may register the patient information.
Subsequently, a method of utilizing the measuring system 1 will be described. In order to use the measuring device 3, first, the urine bag 100 is set to the measuring device 3. Subsequently, a power source button (not illustrated) of the measuring device 3 is pressed. Accordingly, the power source of the measuring device 3 is turned on. When the measurement button B is pressed, the measuring device 3 starts measurement. When the measurement button B is pressed, the measuring device 3 performs zero-point calibration. At this time, when equal to or more than a predetermined amount of urine is stored in the urine bag 100, that is, when urine of an amount equal to or more than “zero-point range” is stored in the urine bag 100, the measuring device 3 does not perform zero-point calibration. The measuring device 3 starts to measure a urinary output after zero-point calibration. When measurement of a urinary output starts, the measuring device 3 transmits urinary output information to the management device 5. When the urinary output information is received, the management device 5 inputs a value based on the urinary output information in electronic medical records.
As described above, in the measuring system 1 according to the present embodiment, the measuring device 3 calculates the voided volume and the urinary output per unit time and transmits urinary output information to the management device 5. Accordingly, the management device 5 can acquire urinary output information by receiving the urinary output information. In this manner, in the measuring system 1, even if a staff member does not visit a hospital room, the voided volume or the like can be checked on the basis of urinary output information in the management device 5. Therefore, there is no need for a staff member to perform work of visual checking. For this reason, in the measuring system 1 including the measuring device 3, reduction of a burden on a staff member can be achieved. In addition, it is possible to reduce a burden on a staff member performing checking at night, that is, performing work in the darkness with less manpower.
The measuring device 3 includes the first battery 22 supplying power to the weighing unit 12, the control unit 14, and the communication unit 18 when power is not supplied from the power source unit 20. For this reason, in the measuring device 3, for example, when a patient temporarily moves, each unit can be driven even if the power source outlet PO is not secured. Therefore, a burden on a staff member can be reduced. In addition, in the measuring device 3, power can be supplied to each of the units (the weighing unit 12, the control unit 14, and the communication unit 18) while the measuring device 3 is moving or the like. Therefore, in the measuring device 3, urinary output information can be transmitted to the management device 5 even while the measuring device is moving or the like.
In the measuring system 1 according to the present embodiment, the measuring device 3 includes the touch panel display 16 capable of displaying urinary output information. The control unit 14 acquires the state of the first battery 22 and causes the touch panel display 16 to display the acquired state of the first battery 22. In this configuration, the state (residual quantity or the like) of the first battery 22 can be checked in the touch panel display 16.
In the measuring system 1 according to the present embodiment, the control unit 14 of the measuring device 3 causes the touch panel display 16 to display that the residual quantity has decreased when the residual quantity of the first battery 22 becomes equal to or smaller than the threshold. In this configuration, when the residual quantity of the first battery 22 has decreased, it is possible to notify that the first battery 22 needs to be charged.
In the measuring system 1 according to the present embodiment, the control unit 14 of the measuring device 3 determines anuria, oliguria, and polyuria on the basis of urinary output information and a threshold set in advance and outputs notification information when it determines anuria, oliguria, or polyuria. In this configuration, a staff member can be notified of anuria, oliguria, or polyuria.
In the measuring system 1 according to the present embodiment, the measuring device 3 includes the second battery 23 supplying at least power for memory back-up when power is not supplied from the power source unit 20 and the first battery 22. In this configuration, even when power is not supplied from the power source unit 20 and the first battery 22, setting and the like in the measuring device 3, such as setting of a timepiece, measurement results, and measurement history can be maintained by the second battery 23.
