When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0058] Regarding urine data, since it is completely measured manually by oneself, there are not only problems such as misrecording, missing recording, over-recording, and duplicate recording, but the most important thing is that it requires a lot of energy from medical staff, resulting in a large labor intensity for medical staff.

[0059] The present invention provides a urine storage device.

[0060] Please refer to Figure 1 , in an embodiment of the present invention, the urine storage device 100 includes: a container 1, a capacitance sensor 2, a control device, a display screen 3, and a signal transmitting device; the container 1 has a cavity 11 with an open end for storing urine; the capacitance sensor 2 is arranged on the periphery of the container 1 for measuring the volume of the stored urine; the control device is electrically connected to the capacitance sensor 2, and the control device includes a timing module; the display screen 3 is electrically connected to the control device and has a measurement urine volume display column, an actual urine volume display column, and a detection duration display column; the signal transmitting device is electrically connected to the control device for sending a prompt signal.

[0061] In the technical solution of the present invention, the urine storage device 100 includes a container 1 for containing the urine of a patient during a detection period. A capacitance sensor 2 is arranged on the periphery of the container 1. Since the amount of urine inside the container 1 is different, the capacitance sensor 2 has different corresponding medium parameters, and thus the electrical signals (capacitance values) are also different. Therefore, the medium parameters can be calculated based on the electrical signals, and then the urine volume can be deduced. In addition, the time of each urine injection and the time interval can be obtained by a timing device. The urine storage device 100 further includes a display screen 3. The display screen 3 has a measured urine volume display column, an actual urine volume display column, and a detection duration display column. The measured urine volume display column is used to display the amount of urine inside the container 1. Since a nurse may take out a small amount of urine from the container 1 for testing, the urine volume inside the container 1 may not be equal to the volume of urine excreted by the patient. The actual urine volume display column is for displaying the volume of urine excreted by the patient. The detection duration display column is used to display the duration since the start of detection, or to display the countdown of the detection period at the start of detection. After the detection period duration ends, the signal transmitting device can send a prompt signal to prompt the medical staff that the detection period has ended, and can send the urine data of the patient during the detection period to the hospital's medical system for subsequent reference and management by the medical staff. This urine storage device 100 omits the work steps of medical staff for measuring, recording, and transmitting urine information, so as to reduce the work intensity of medical staff.

[0062] When the urine specimen cannot be sent for inspection in time, formaldehyde can be dropped into the urine for anti-corrosion fixation to ensure the stability of urine components. For some special inspection items that require detecting organic components or cell morphology in urine, such as urine sediment examination, urine protein quantification, etc., formaldehyde fixation can improve the accuracy of the inspection results. Therefore, the urine storage device 100 further includes: a cover body 4 and a first opening and closing member 5. The cover body 4 is installed at the opening position of the cavity 11. The cover body 4 is provided with a urine inlet 41, a storage cavity 42, and a dropper opening 43. The urine inlet 41 is used for injecting urine into the cavity 11. The storage cavity 42 is used for storing formaldehyde solution. The dropper opening 43 is used to connect the storage cavity 42 and the cavity 11. The first opening and closing member 5 is installed at the dropper opening 43 and is electrically connected to the control device. When it is first detected that urine is injected into the container 1, the first opening and closing member 5 is controlled to open, so that the formaldehyde solution in the storage cavity 42 drips into the cavity 11, thereby achieving an anti-corrosion effect. In addition, the amount of formaldehyde solution added is relatively small and can be ignored, without affecting the measurement of the overall urine volume.

[0063] To facilitate the nurse in sampling from container 1, the urine storage device 100 further includes: a sampling tube 6 and a second opening / closing member 7. The sampling tube 6 communicates with the cavity 11 of the container 1. The second opening / closing member 7 is installed on the sampling tube 6. When the medical staff opens the second opening / closing member 7, urine can be collected from one end of the sampling tube 6 for testing. There is no need to open the cover 4 to pour out some urine to avoid urine spillage. In addition, the second opening / closing member 7 is electrically connected to the control device so that when the second opening / closing member 7 is opened, it sends an opening signal to the control device. So that the controller can obtain the urine volume data before the opening signal and the urine volume data after the opening signal, and calculate the volume of urine taken out each time according to the difference in urine volume before and after.

[0064] In addition, to prevent the urine storage device 100 from shutting down due to insufficient power during the detection period, resulting in data loss. Therefore, in one embodiment, the urine storage device 100 further includes: a battery and a detection device. The battery is electrically connected to the control device. The battery power can be detected by the detection device, and the power information is transmitted to the control device through a power signal. When the power is low, the control device can send a low-power information through the signal transmitting device to prompt the user to charge in time.

[0065] The present invention also proposes a method for controlling a urine storage device. Based on the above urine storage device 100, the control device is provided with a detection period;

[0066] Referring to Figure 2 , Figure 2 is a schematic flowchart of the first embodiment of a method for controlling a urine storage device according to the present invention. The method for controlling a urine storage device includes:

[0067] Step S1: Control the display device to clear the data in the measured urine volume display column, the actual urine volume display column, and the detection duration display column;

[0068] Step S2: Control the display to display the time data measured by the timer in the detection duration display column;

[0069] Step S3: According to the last urine volume data measured by the capacitance sensor 2, use the last urine volume data as the measured urine data, and control the display to display the measured urine data in the measured urine volume display column;

[0070] Step S4: Calculate the actual urine volume data according to the urine volume data, and control the display to display the actual urine volume data in the actual urine volume display column;

[0071] Step S5: When the time data measured by the timer is greater than or equal to the detection period, control the signal transmitting device to emit a first prompt signal;

[0072] The urine storage device 100 is provided with a reset button. Press the reset button to clear the data in the urine volume display bar, the actual urine volume display bar, and the detection duration display bar of the display device, so as to prevent the problem of subsequent display not matching the actual situation. Each detection period starts to collect data and time only after the user manually presses the start button. After manual startup, the detection duration display bar displays relevant time information. Since the detection period is set manually, relevant time information can be known according to the detection duration display bar, that is, how much detection duration has been carried out and how much detection duration remains. Because the urine is injected into the container 1 in multiple times, the data in the urine volume display bar needs to be updated in time. Therefore, the last urine volume data measured by the capacitance sensor 2 (i.e., the latest measured urine volume data) is used as the measured urine data, and the control display device displays the measured urine data in the urine volume display bar to ensure the accuracy of the data. Since sampling detection is involved during the detection period, the urine volume in the container 1 is not equal to the actual urine volume excreted by the patient. And medical staff need to know the actual urine volume excreted by the patient to judge whether the patient's kidney function is normal. Therefore, it is necessary to calculate the actual urine volume data and then display the actual urine volume data in the actual urine volume display bar, so as to facilitate medical staff to directly read. The specific method steps for calculating the actual urine volume data will be explained later. When the detection time exceeds the detection period, control the signal transmitting device to emit a first prompt signal. The first prompt signal may include, but is not limited to, the following content: a detection period end signal, which can be displayed through a sound or light alarm device, or sent to the nurse's mobile phone in the form of a text message. In addition, the actual urine volume data and the time information of each urine injection during this detection period can be uploaded to the medical system through the network.

[0073] Specifically calculating the actual urine volume data needs to be calculated differently according to whether there is a sampling behavior (i.e., whether an opening signal is received) before this.

[0074] Refer to Figure 3 , Figure 3 is a schematic flowchart of the second embodiment of a urine storage device control method of the present invention. Step S4 includes:

[0075] Step S41: When the control device does not receive the opening signal, control the display device to display the measured urine data in the actual urine volume display bar;

[0076] Step S42: When the control device has received the opening signal, calculate the actual urine volume data according to the difference between the urine volume data measured before and after each reception of the opening signal, and control the display to display the actual urine volume data in the actual urine volume display column.

[0077] When the control device has not received the opening signal, that is, there is no sampling behavior, then the urine volume in container 1 can be equal to the actual urine volume excreted by the patient. Therefore, the measured urine data can be directly displayed in the actual urine volume display column. When the control device has received the opening signal, then there is a sampling behavior, and the urine volume in container 1 is not equal to the actual urine volume excreted by the patient. It is necessary to obtain the urine volumes measured before and after each reception of the opening signal, so as to calculate the volume of the sampled urine, and then calculate the actual urine volume data. The actual urine volume data is displayed in the actual urine volume display column.

[0078] When there is a sampling behavior, the specific calculation method of the actual urine volume data is as follows:

[0079] Refer to Figure 4 , Figure 4 which is a schematic flowchart of the third embodiment of a urine storage device control method of the present invention. Step S42 includes:

[0080] Step S421: Obtain the urine volume data before and after each reception of the opening signal;

[0081] Step S422: Calculate the single-sampling urine volume data: The single-sampling urine volume data = the urine volume data measured before receiving the opening signal - the urine volume data measured after receiving the opening signal, where the opening signal is the same opening signal;

[0082] Step S423: Calculate the total sampled urine volume data: The total sampled urine volume data = the sum of multiple single-sampling urine volume data;

[0083] Step S424: Calculate the actual urine volume data: The actual urine volume data = the total sampled urine volume data + the measured urine data;

[0084] Step S425: Control the display to display the actual urine volume data in the actual urine volume display column.

[0085] Since the sampling behavior may occur multiple times, it is necessary to obtain the urine volume data before and after receiving the start signal each time. For the same start signal, the urine volume data before sampling minus the urine volume data after sampling equals the single-sampling urine volume data. For different start signals, calculate the single-sampling urine volume data corresponding to each start signal, and then sum up the multiple single-sampling urine volume data to obtain the total sampled urine volume data. Adding the total sampled urine volume to the urine volume in container 1 gives the volume of urine excreted by the patient, thereby calculating the actual urine volume data, which is then displayed in the actual urine volume display column.

[0086] To understand whether the patient's kidney function or urinary system is normal, it can be judged based on the patient's urine output. The control device is set with a preset discharge range. The preset discharge range is the urine volume range of normal people.

[0087] Refer to Figure 5 , Figure 5 This is a schematic flowchart of the fourth embodiment of a urine storage control method of the present invention. After step S4, it further includes;

[0088] Step S6: Obtain the last actual urine volume data within the detection period as the total discharge data. When the total discharge data exceeds the preset discharge range, control the signal transmitting device to send a second prompt signal.

[0089] The last actual urine volume data within the detection period is the total amount of urine excreted by the patient during the detection period. If the total discharge data is within the preset discharge range, the patient's physical function is normal; otherwise, there is a problem. The second prompt signal includes, but is not limited to, the total discharge data, the time information of each urine injection, and the corresponding actual urine volume data. It can be sent to the nurse's mobile phone via text message or uploaded to the medical system via the network.

[0090] Since the urine in container 1 is the medium corresponding to the capacitance sensor 2, when the urine in container 1 has not stabilized, since the shape of the urine is constantly changing, the corresponding dielectric constant will also change, so the measured urine volume data will also keep changing. If the last urine volume data is used as the measured urine data and displayed in the measured urine volume display column at this time, it will lead to inaccurate readings. Therefore, it is necessary to take readings when the urine in container 1 is stable or the oscillation amplitude is small. The control device is set with a preset fluctuation amplitude and a preset detection duration range. The last urine volume data is one of the urine volume data measured by the capacitance sensor 2 within the preset detection duration range. When the urine volume data within the preset detection duration range fluctuates less than the preset fluctuation amplitude, it indicates that the urine state in container 1 is relatively stable, and readings can be taken at this time.

[0091] Reference Figure 6 , Figure 6 This is a flow chart of a fifth embodiment of a urine storage device control method of the present invention. Step S3 includes:

[0092] Step S31: obtaining the maximum urine volume data, the minimum urine volume data and the last urine volume data measured by the capacitance sensor 2 within the preset detection time interval;

[0093] Step S32: when the maximum urine volume data minus the minimum urine volume data < the preset fluctuation amplitude, the last urine volume data is used as the measured urine data, and the display is controlled to display the measured urine data in the measured urine volume display column;

[0094] Step S33: When the maximum urine volume data - the minimum urine volume data ≥ the preset fluctuation amplitude, return to the step of "obtaining the maximum urine volume data, the minimum urine volume data and the last urine volume data measured by the capacitive sensor 2 within the preset detection time interval".

[0095] During the process of urine stabilizing in the area after shaking, the urine state corresponding to the last urine volume data (i.e. the latest urine volume data) is the most stable. The maximum urine volume data and the minimum urine volume data measured within the preset detection time interval are obtained. When the difference between the maximum urine volume data and the minimum urine volume data is less than the preset fluctuation amplitude, it means that the urine state in container 1 is relatively stable and the reading can be taken at this time. The last urine volume data is used as the measured urine data, and the control display displays the measured urine data in the measured urine volume display column; when the difference between the maximum urine volume data and the minimum urine volume data is greater than or equal to the preset fluctuation amplitude, it means that the urine is still in a strong agitation state and needs to be left to stand; the latest last urine volume data is obtained again, as well as the new maximum urine volume data and the new minimum urine volume data within the preset detection time interval.

[0096] When urine is injected into the container 1, formaldehyde solution needs to be added immediately for preservation. In order to prevent the formaldehyde solution from being added artificially in time, the formaldehyde is added automatically.

[0097] Reference Figure 7 , Figure 7 This is a flow chart of a sixth embodiment of a urine storage device control method of the present invention. After step S1, it also includes:

[0098] Step S7: When the urine volume data measured by the capacitance sensor 2 is received for the first time and is greater than 0, the first opening and closing member 5 is controlled to open, and then closed after being kept open for a preset time.

[0099] When the urine volume data is detected to be greater than 0, it indicates that urine has been injected into the container 1. At this time, the first opening and closing member 5 is opened to allow the formaldehyde solution to drip into the cavity 11. The first opening and closing member 5 is closed after being kept open for a preset time to control the volume of the dripping formaldehyde solution.
