The processing element 120 is electrically connected to the weight sensor 110, and is used to receive the weight of the urine collection bag measured by the weight sensor 110, and send a warning when the urine in the urine collection bag is about to be full The information is sent to the alarm component 140 to notify relevant personnel to proceed to process. The warning element 140 is used for receiving warning information and emitting a warning sound or light. The communication element 130 is used to transmit the weight of the urine collection bag measured by the weight sensor 110 to the remote medical care platform 200 or the handheld device 300 of the medical staff through the Internet 210 for real-time monitoring. And receive the setting information sent by the remote medical care platform 200 or the handheld device 300 of the medical personnel. The color detection element 150 is used to detect the color of the urine in the urine collection bag, and the processing element 120 is used to receive the color of the urine detected by the color detection element 150, and when the color of the urine is abnormal, send a warning message to the alarm element 140 for notification Relevant personnel went to deal with it. The communication element 130 is used to transmit the urine color detected by the color detection element 150 to the database storage of the remote medical care platform 200 or the handheld device 300 of the medical staff through the Internet 210 for real-time monitoring or subsequent data extraction Use, for example, to detect changes in urine color. In one embodiment, the color detection element 150 is installed near the urine collection bag at a position where the color of the urine can be detected, and the color of the detected urine is transmitted to the processing element 120 in a wired or wireless manner, and uploaded to the remote The database of the terminal medical and nursing platform 200 saves the work of nursing staff to record the color of urine.

The remote medical care platform 200 or the hand-held device 300 of the medical staff is used to receive the weight of the urine collection bag transmitted by the communication element 130 for storage, and compare the weight of the urine collection bag with the alarm weight to determine when the urine bag is about to be full. Notify the relevant personnel to deal with it. Among them, the alarm weight is the critical value of urine that can be stored in the urine collection bag. When the urine stored in the urine collection bag is greater than the critical value, that is, the alarm weight, it means that the urine collection bag is about to be full, that is, when the monitoring set When the weight of the urine bag is greater than or equal to the alarm weight, the processing component 120 triggers the alarm component 140 to send a warning message to inform relevant personnel to go to process.

In another embodiment, according to the weight of the urine collection bag measured by the weight sensor 110 , the urine output per unit time of the care receiver can be calculated to determine whether the urine output of the care receiver is normal. As shown in FIG. 2 , it is a schematic diagram of output urine output data of a care recipient, wherein the horizontal axis is time, and the vertical axis is the weight of the urine collection bag monitored by the real-time urine monitoring system 100 . In one embodiment, the corresponding weight at time t1 is the weight of the urine collection bag after the urine collection bag has been emptied, that is, the empty bag weight of the urine collection bag, for example, G1 grams. Because the care recipient will continue to urinate, therefore, after time t1, the weight of the urine collection bag monitored by the urine real-time monitoring system 100 will continue to increase until time t2 when the urine collection bag is emptied again, for example, the weight measured at time t2 The weight is G2 grams. According to this, the processing unit 120 can subtract the previous minimum value from the highest weight value before the urine is poured out, that is, the weight of the urine collection bag at time t2, that is, the urine collection time at time t1, according to the weight monitored by the weight sensor 110 The weight of the urine collection bag after the bag is emptied, the weight of the empty bag of the urine collection bag, and the total urine volume output by the care recipient within this time interval, from t1 to t2, is calculated. Total urine output = G2-G1.

It is worth noting that the above calculation is the total urine volume output by the care recipient within the time interval, from t1 to t2. However, it can also be set according to the user's needs to evaluate the total urination of the care recipient within a unit time, such as every 1 hour, 4 hours, 8 hours, 12 hours or 24 hours. In another embodiment, the remote medical care platform 200 can also calculate the weight of the urine volume of the care recipient in each 1 hour, 4 hours, 8 hours, 12 hours or 24 hours time interval according to the weight of the urine output in the time interval monitored by the weight sensor 110. Always urinate. In this embodiment, the total urine output calculated by the remote medical care platform 200 can also be sent back to the real-time urine monitoring system 100 for display on the display device 160 of the real-time urine monitoring system 100, or can be sent back to the medical staff. The handheld device 300 displays on the screen of the handheld device 300, so that the clinical nurse or physician can instantly confirm whether the urine output of the care recipient is normal when making rounds.

The operation of the real-time urine monitoring system 100 will be described in detail below with reference to FIG. 1 and FIG. 3 . Please refer to Figure 1 and Figure 3. FIG. 3 is a flowchart of a real-time urine monitoring method 30 according to some embodiments of the present application. The real-time urine monitoring method 30 can be applied to the real-time urine monitoring system 100 in FIG. 1 . The urine real-time monitoring method 30 includes the following steps (it should be understood that the steps mentioned in this embodiment, except those whose order is specifically stated, can be adjusted according to actual needs, and can even be simultaneously or partly simultaneously implement).

In step S310 , the processing unit 120 receives the setting information sent by the remote medical care platform 200 . In one embodiment, the remote medical care platform 200 can access the setting information of different urine collection bags, and the setting information includes the empty weight of the urine collection bag and the alarm weight of the urine collection bag that generates warning information. Therefore, when the user wants to install the urine collection bag on the real-time urine monitoring system 100, the processing unit 120 can be used to download the setting information of the corresponding urine collection bag on the remote medical care platform 200 through the network, and then transmit it to the weight sensor 110 .

In step S320, the weight of the urine collection bag is sensed by the weight sensor 110 and sent to the processing unit 120, so that the weight of the urine collection bag is calculated by the processing unit 120 in step S330. In one embodiment, when the urine collection bag is installed with the real-time urine monitoring system 100, the weight sensor 110 will start to sense the weight of the urine collection bag, and transmit the sensed weight value of the urine collection bag to The processing component 120 continuously calculates the weight value of the urine collection bag sensed by the weight sensor 110 .

In step S340, the processing unit 120 determines whether the weight of the urine collection bag is greater than the alarm weight of the urine collection bag. In one embodiment, the processing element 120 judges whether the weight of the urine collection bag is greater than the alarm weight of the urine collection bag according to the weight value of the urine collection bag received from the weight sensor 110, and if not greater than the alarm weight of the urine collection bag, then perform the steps S320, continue to sense the weight of the urine collection bag through the weight sensor 110 . If it is greater than the alarm weight of the urine collection bag, then step S350 is executed to trigger the alarm component 140 to send a warning message to inform relevant personnel to go for processing.

In one embodiment, in step S320, the weight of the urine collection bag is sensed by the weight sensor 110 and sent to the processing unit 120, and the communication unit 130 is used to transmit the weight of the urine collection bag measured by the weight sensor 110. The weight is transmitted to the database storage of the remote medical care platform 200 or the handheld device 300 of the medical staff through the Internet 210. In addition to real-time monitoring, the stored historical weight data can also be used to judge the change of the urine volume of the care recipient . In another embodiment, in step S320, the processing unit 120 can further calculate and display the total urine output of the care receiver within a time interval according to the weight monitored by the weight sensor 110. The technique is as follows: The foregoing will not be repeated here.

On the other hand, the real-time urine monitoring system 100 of this case further includes a color detection element 150 for detecting the color of the urine in the urine collection bag. Therefore, step S320 of this case may further include detecting the color of the urine through the color detection element 150 and Send it to the processing unit 120 to receive the urine color detected by the color detection unit 150 through the processing unit 120 in step S340, and when the urine color is abnormal, send a warning message to the alarm unit 140 to inform relevant personnel to go to deal with it. The communication component 130 is used to transmit the urine color detected by the color detection component 150 to the remote medical care platform 200 or the handheld device 300 of the medical staff through the Internet 210 for real-time monitoring and recording of the urine color.

In another embodiment, the weight sensor 110 can be automatically reset to zero. In one embodiment, in order to prevent the weight sensor 110 from performing calibration in an abnormal state, for example, the weight sensor 110 is in a tilted or lying state, or the weight sensor 110 is in a moving or shaking state , causing the current calibration weight to be inaccurate, resulting in calibration weight failure. Therefore, the weight sensor 110 in this case further includes a gravity sensor 1101 for sensing motion data of the weight sensor 110 . When the processing unit 120 executes the automatic zero calibration of the weight sensor 110 , the gravity sensor 1101 will first determine whether the motion data of the weight sensor 110 is in the set calibration orientation before performing calibration. In one embodiment, the calibration orientation is the orientation where the hook used by the weight sensor 110 to hang the urine collection bag is perpendicular to the ground. Accordingly, when the weight sensor 110 is performing calibration, the processing element 120 will first read the motion data value detected by the gravity sensor 1101, and determine whether the motion data value is within the calibration orientation, and if so In the calibration orientation, the processing component 120 performs auto-zero calibration on the weight sensor 110 . On the contrary, if it is not within the calibration orientation, that is, the hook is not perpendicular to the ground, the processing component 120 prohibits the weight sensor 110 from performing zero calibration, and notifies relevant personnel for processing. The gravity sensor 1101 can be an accelerometer (G-Sensor), a magnetometer (M-Sensor), a gyroscope (Gyroscope), a gravity sensor (GV-Sensor), a linear acceleration sensor (LA-Sensor), Rotation vector sensor (RV-Sensor), tilt angle sensor (Tilt-Sensor) or the assembly of the above devices. Wherein, the gravity sensor 1101 directly provides three-axis sensing signals, which are X-axis acceleration (velocity) parameters, Y-axis acceleration (velocity) parameters, and Z-axis acceleration (velocity) parameters.

In another embodiment, the above-mentioned zero-return calibration in this case can be determined by the processing unit 120 when the weight sensor 110 is in an empty state, and directly controls the weight sensor 110 to automatically perform zero-return calibration, or manually controlled by the operator. The weight sensor 110 performs zero calibration. Wherein the empty state is that no urine bag is mounted on the weight sensor 110 . In one embodiment, an empty weight value can be set. When the processing element 120 receives the weight sensed by the weight sensor 110 and judges that the weight value at this time is less than the empty weight value, the processing element 120 determines that the weight sensor 110 is In an empty state, the direct control weight sensor 110 automatically performs zeroing calibration.

In one embodiment, the weight sensor 110 of this case is a strain gauge weight sensor, so before leaving the factory, the weight sensor 110 of this case will manually perform a 0-gram emptying calibration and a 1000-gram calibration by the operator, so as to Calculate the basis of the calculation weight formula of the weight sensor 110 . When the weight sensor 110 needs to be maintained after leaving the factory in the future, the operator can periodically manually perform a 0-gram emptying calibration and a 1000-gram calibration to ensure that the weight calculated by the weight sensor 110 is accurate. Therefore, in this embodiment, before any manual calibration is performed, the gravity sensor 1101 can be used to determine whether the motion data of the weight sensor 110 is in the set calibration orientation, and the weight calibration can only be performed in the calibration orientation and store, otherwise no correction and store will be performed. In other embodiments, other weight calculation functions with different gram numbers can be used, for example, the operator manually performs a 0-gram emptying correction and a 500-gram correction, and the basis for calculating the weight formula of the weight sensor 110 can also be calculated.

In another embodiment, the care recipient moves together with the urine real-time monitoring system 100 on which the urine collection bag is suspended. Therefore, the weight sensor 110 of this application further includes a positioning element 1102 for positioning by the positioning element 1102 . Fig. 4 shows a positioning system diagram according to an embodiment of the present case. In a preferred embodiment, if the positioning component 1102 used is a Bluetooth signal transmission component, in order to perform positioning, a plurality of signal receivers 400, such as Bluetooth signal receivers, will be set at different positions in a medical institution , wherein each positioning element 1102 of the real-time urine monitoring system 100 has an identification code. When one of the signal receivers 400 detects the bluetooth signal of the positioning element 1102 and receives the identification code in the bluetooth signal, it will report the identification code to the remote medical care platform 200, so as to determine which urine is based on the identification code. Real-time urine monitoring system 100, and according to the location of the signal receiver 400 that reports the identification code to the remote medical care platform 200, locates the location of the real-time urine monitoring system 100 in the medical institution. It should be noted that the above-mentioned positioning method is only an example and is not intended to limit the implementation of this case. Other known positioning methods can also be used in this case to position the real-time urine monitoring system 100 .

In another embodiment, the weight sensor 110 includes a gravity sensor 1101 and a positioning element 1102 . The gravity sensor 1101 can sense motion data such as acceleration, angular acceleration, direction, and movement amount of the urine collection bag. Use the above motion data to identify the real-time use status of the urine bag, and indirectly judge whether the care recipient's posture may fall or the urine bag may be dumped. Wherein, the positioning component 1102 can simultaneously broadcast its own identification code and the real-time motion data detected by the gravity sensor 1101 as a bluetooth signal. The remote medical care platform 200 can judge the position of the care recipient in the medical institution and whether its posture is abnormal based on the identification code and motion data, and then dispatch caregivers to take care of it in real time to avoid danger.

As can be seen from the implementation of the above case, it is mainly to improve the previous process of monitoring the urine collection bag by using manual monitoring, using a weight sensor to sense the weight of the urine collection bag in real time, when the weight of the urine collection bag is greater than or equal to the critical value When the urine color is abnormal, an alarm will sound to remind the caregiver that the urine collection bag needs to be tested. At the same time, this case also includes a color detection device to detect the color of the urine in time, and when the color of the urine is abnormal, the alarm will sound to notify the relevant personnel to deal with it. In order to achieve real-time monitoring of the efficacy of the urine collection bag. Furthermore, in this case, a gravity sensor and a positioning element can be further arranged on the weight sensor. The motion data is sensed by the gravity sensor to determine whether to perform automatic zero calibration or manual calibration process, eliminating the disadvantage of automatic zero calibration or manual calibration performed by the weight sensor in an abnormal orientation. Furthermore, it is possible to judge whether an accident has occurred to the care recipient according to the real-time motion data, and send caregivers to take care of it according to the real-time positioning of the positioning element, so as to avoid danger.

Additionally, the above illustrations contain sequential exemplary steps, but the steps do not have to be performed in the order presented. It is within the contemplation of the present disclosure to perform the steps in a different order. These steps may be added, substituted, changed in order and/or omitted as appropriate within the spirit and scope of embodiments of the present disclosure.

Although this case has been disclosed as above by means of implementation, it is not used to limit this case. Anyone who is familiar with this technology can make various changes and modifications without departing from the spirit and scope of this case. Therefore, the scope of protection of this case should be regarded as an afterthought. The one defined in the scope of the attached patent application shall prevail.
