Description

The present invention is an invention relating to an excrement photographing apparatus attached to a flush toilet and taking an image of excrement.

As a conventional excrement photographing device, in order to compare with the clinically general Bristol scale, a device that captures and manages an excrement image when excreted with a toilet bowl is known. (See, for example, Patent Document 1.).
In addition, when multiple patients use one toilet bowl as in a hospital, we have acquired personal authentication data to identify the excretor so that we can manage which patient the captured image data belongs to. It is also known that the personal authentication data and the excrement image data are output (see, for example, Patent Document 2).

However, in the conventional excrement photographing device, it is necessary to install a device for photographing and collecting image data of excrement integrally with the toilet bowl or another toilet seat device, and it is necessary to install the toilet bowl or the toilet seat. In some cases, the toilet bowl and toilet seat device had to be replaced according to the excrement imaging device, which has a shorter life than the device.

The area of the sealed water is photographed to generate digitized image data. Also, next to the photographing means 6,
The excrement detecting means 8 is fixed in the bowl portion 102 so as to face each other. This excrement detecting means 8
Is an ultrasonic sensor, which detects excrement that has fallen into the sealing water by detecting a change in the water level of the sealing water at the bottom of the bowl portion 102 by an ultrasonic reflection time change.

Further, a personal identification means 10 is provided on the wall surface of the toilet room. In the present embodiment, an inpatient in a hospital is assumed as a user, and therefore, the personal identification means 10 is configured by a barcode reader. The personal identification means 10 is a personal magazine identification data (I) for identifying an individual patient printed on a wristband or the like held by an inpatient.
The barcode including the D number) is read, and the read data can be wirelessly transmitted to the function box unit 4.

Next, the function of the excrement photographing apparatus 1 according to the present embodiment will be described with reference to FIG.

As shown in FIG. 2, the function box unit 4 houses a control means 12 for controlling the operation of the photographing means 6 and the excrement detecting means 8. The detailed control operation by the control means 12 will be described later.

Further, the function box unit 4 houses a receiving means 14 for receiving a signal including personal identification data wirelessly transmitted from the personal identification means 10. The control means 12 integrates the personal identification data received by the receiving means 14 with the image data of the excrement photographed by the photographing means 6, and outputs the personal identification data as one set of output data to the transmitting means 16. The transmission means 16 wirelessly transmits the output data of the set to the router 50 installed in the toilet room.
This router 50 is a relay terminal in wireless communication, and it is possible to install a commercially available device in the toilet room (see FIG. 3) and use it.

The output data transmitted to the router 50 is sent to the server 54 installed at a predetermined location in the hospital through the LAN 52 installed in the hospital and stored. This server 5
The output data stored in 4 can be used by an information terminal 56 such as a personal computer or a portable information terminal. In the information terminal 56, by designating the personal identification data (ID number) of a specific patient by the program (application software) built therein, the data of the patient can be read from the server 54 and confirmed, or the server. It is possible to narrow down the data to be read from the server 54 by specifying the period stored in 54.

Next, the usage state of the excrement photographing apparatus 1 will be described.
FIG. 3 is a perspective view in which a sanitary cleaning device is attached to the excrement photographing device according to the embodiment of the present invention. As shown in FIG. 3, a local cleaning device 200 as a toilet seat device is attached to the upper surface of the plate portion 2 in the excrement photographing device 1. The local cleaning device 200 has a built-in local cleaning function unit that discharges cleaning water toward the user's local area in the casing 202. A toilet seat 204 is rotatably supported on the casing 202. On the wall surface of the toilet room, a local cleaning remote controller 206 for operating the local cleaning device 200 is installed along with a barcode reader as the personal identification means 10.

As described above, since the plate portion 2 has a flat plate shape, the local cleaning device 2 is placed on the upper surface of the plate portion 2.
Even if 00 is placed, the mounting height of the local cleaning device 200 is almost unchanged. Therefore, the excrement photographing device 1 is used for the toilet room in which the local cleaning device 200 is installed in the flush toilet bowl 100. Can be retrofitted. Further, the excrement photographing device 1 is a local cleaning device 20.
Since it is attached to the flush toilet 100 independently of 0, when the photographing means 6 deteriorates over time and reaches the end of its life, only the excretion photographing device 1 is replaced without replacing the local cleaning device 200. be able to. The photographing means 6 fixed to the plate portion 2 is hidden by the casing 202 of the local cleaning device 200, and the presence of the photographing means 6 can be made inconspicuous to the user.

A cabinet 210 is provided behind the flush toilet 100 so as to cover the flush water tank 104. On the front surface of the cabinet 210, a backrest portion 21 having a cushioning property
2 is provided. A router 50 is provided on the cabinet 210. The router 50 is a relay terminal for transmitting the output data output from the excrement photographing device 1 to the LAN in the hospital.

The cabinet 210 contains a urine volume measuring device 300 that measures biological information such as the amount of urine excreted by the user (subject) and the urine flow rate (the amount of urine excreted per unit time). The urine volume measuring device 300 is a water level measuring pipeline (not shown) that communicates with the sealing water of the flush toilet bowl 100.
It is possible to measure the urine volume and urine flow rate by changing the water level in the water level measurement pipe during urination. On the wall surface of the toilet room, a urine volume measuring remote controller 302 is provided above the local cleaning remote controller 206. The urine volume measurement remote control 302 is provided with a measurement start switch for instructing the start of urine volume measurement, a urine volume measurement end switch for instructing the end of urination, and the like.

Next, the operation of the excrement detecting means 8 in the present embodiment will be described. FIG. 4 is a water level change graph showing an example of excrement detection of the present invention. In FIG. 4, the rate of change in the water level of the sealed water formed at the bottom of the bowl portion 102 is shown graphically for each of stool and urine (urine) over time. Since a large volume of stool is submerged in a short time, the rate of change in the water level of the sealed water is large, and the time is generally short. On the other hand, since urine is excreted through the long urethra, the rate of change in the water level of the sealed water is suppressed, and on the contrary, the rate of change in the water level generally continues for a long time. The excrement detecting means 8 detects a change in the water level of the sealed water by a change in the reflection time of ultrasonic waves, and based on this change in the water level, excrement is excreted in either case of stool or urine. It is possible to detect the timing.

Next, the operation of the excrement photographing apparatus 1 will be described. FIG. 5 is a flowchart showing the operation of the excrement photographing apparatus according to the embodiment of the present invention, and specifically shows the control flow by the control means 12 of the excrement photographing apparatus 1.
When the power of the excrement photographing apparatus 1 is turned on and the control means 12 is energized, the control sequence is started (S100). In this state, the control means 12 is in the standby state, and the photographing means 6
And the excrement detecting means 8 is not energized, and the receiving means 14 is energized and the receiving means 1 is energized.
It is in a state of waiting for a signal from 4.

In this standby state, it is determined whether or not the signal from the personal identification means 10 has been received by the receiving means 14 (S101). Specifically, the user (patient) holds a wristband on which a barcode containing personal identification data wrapped around the wrist is printed over the barcode reader of the personal identification means 10, and receives the barcode information. It is determined whether or not 14 has been received. When the receiving means 14 does not receive the barcode information (S101N), the control means 12
Repeats the process of S101. When the receiving means 14 receives the barcode information (S1)
01Y), the control means 12 starts energization to activate the photographing means 6 and the excrement detecting means 8 (S102).

Subsequently, in S103, it is determined whether or not excretion has been performed by the excrement detecting means 8.
When the excrement detection means 8 does not detect the excretion of either stool or urine (S103N)
), The control means 12 repeats the process of S103. When the excrement detecting means 8 detects the excretion of either stool or urine (S103Y), the photographing means 6 starts photographing in S104. The method of detecting the start of excretion is the time when the water level of the sealed water changes due to the excrement of either stool or urine shown in FIG.

Subsequently, the process of S105 is executed, and in the process of S106 after the process of S105, the control means 12 determines whether or not the excretion is completed. Specifically, the control means 12 monitors the water level change signal from the excrement detecting means 8, and determines the end of excretion when the state where there is no water level change continues for a predetermined time.
While the excretion continues (S106N), the control means 12 returns to the process of S105 and continues imaging, and the processes of S105 and S106 are repeatedly executed until the excretion is completed.
It should be noted that the shooting by the shooting means 6 does not have to be a moving image, and it is preferable to shoot a still image at intervals of several seconds in consideration of reducing the capacity of the image data and checking the excrement.
When it is determined that the excretion is completed (S106Y), the imaging by the imaging means 6 is terminated, and the image data captured after the start of imaging (S104) and the identification transmitted from the personal identification means 10 to identify the user (patient) are identified. The output data in which the barcode signal (see S101) including the signal is integrated is transmitted from the transmission means 16 to the router 50. Subsequently, in S108, the energization of the photographing means 6 and the excrement detecting means 8 is stopped, the state shifts to the standby state, and the process returns to the processing of S101.

In the excretion photographing apparatus 1 of this embodiment, since the photographing is started immediately after the excretion detection (S103Y), it is possible to capture an image of the excrement without obstacles such as toilet paper immediately after the excretion. Further, since the photographing period is limited to the period from the start of excretion to the end of excretion, the excrement can be reliably photographed and the data capacity of the image data can be suppressed from being unnecessarily increased. Also, because the captured image data is transmitted and output to the outside,
By accessing the server 54 in which the image data is stored, the medical staff can view the excrement image data in a timely manner without going to the toilet room and directly accessing the excrement photographing device 1 installed there. It can be done and workability can be improved. Healthcare workers are not disrupted in their work just to see the excrement, and above all, the patient is not under the mental pressure of showing the excrement directly.

The embodiments of the present invention have been described above. However, the present invention is not limited to these descriptions. With respect to the above-described embodiments, those skilled in the art with appropriate design changes are also included in the scope of the present invention as long as they have the features of the present invention.
For example, the excrement detecting means 8 can be in various modes instead of the above-mentioned one that detects the change in the water level of the sealed water by the reflection time of ultrasonic waves. For example, the gas generated by the excrement may be detected. Carbon dioxide, hydrogen, methyl mercaptan, trimethylamine, etc. are recommended for stool, and ketone bodies such as acetoacetic acid, 3-hydroxybutyric acid, and acetone are recommended for urine in an abnormal state.
Further, as another mode of the excrement detecting means 8, the excrement may be detected by paying attention to the temperature of the excrement itself or by changing the temperature of the inside of the bowl portion 102 or the sealing water.

Further, the imaging period of the photographing means 6 may be set to a predetermined fixed time from the excretion start determination instead of photographing from the excretion start determination to the excretion end determination by the excrement detecting means 8. Further, the user may input the start of shooting and the end of shooting.
Further, instead of wirelessly transmitting the output data from the transmitting means 16 as the output means to the router 50, a storage means for storing the output data is provided inside the function box unit 4 to engage in medical treatment. An output port for a person to access the storage means and output output data may be provided as an output means, or by setting the storage means itself as a card-type memory, this card-type memory can be used as an output means. It may be possible to take out from the output slot as.

Further, instead of installing the personal identification means 10 on the wall surface of the toilet room, the functional box portion 4
It may be built in. Further, the personal identification means 10 does not have to be a barcode reader, and the user may input an ID number for identifying an individual.
Further, the photographing means 6 is provided with an electric shutter that opens and closes the lens portion of the camera. It may be possible to prevent the lens from being contaminated by splashed water during local cleaning by the local cleaning device 200 or when cleaning the flush toilet 100 after the shooting is completed.
Further, a cleaning means for wiping the lens surface when the shutter is opened and closed may be provided, and a function of automatically cleaning the photographing means 6 to which excrement droplets are likely to adhere may be provided.
