[0048] Figure 1 Shown is a block diagram of an infusion monitoring system capable of automatic calibration according to an embodiment. The infusion monitoring system 100 includes: a weighing device 102, a storage element 104, an alarm element 106, a processing element 108, and a communication element 110. The processing element 108 is electrically coupled to the weighing device 102, the storage element 104, the alarm element 106, and the communication element 110. In one embodiment, the infusion monitoring system 100 can be connected to the Internet through the communication element 110 and connected to a remote medical platform or a handheld device of medical staff to transmit the real-time monitoring values of the infusion monitoring system 100 to the remote medical platform or the handheld device of medical staff, where the handheld device of medical staff can be a small portable electronic device such as a tablet computer, a smart phone, a personal digital assistant, etc. The processing element 108 can be a central processing unit (CPU) or other programmable microprocessor, etc. In one embodiment, the processing element 108, the weighing device 102, the storage element 104, the alarm element 106, and the communication element 110 of the present case can be jointly arranged in a box to form the infusion monitoring system 100 of the present case.
[0049] Among them, the weighing device 102 is configured to measure the weight of the object to be measured, and the object to be measured can be, but is not limited to, an infusion bag or an infusion bottle. The processing element 108 can perform subsequent processing based on the weight measured by the weighing device 102. The storage element 104 can include various types of storage units, such as, but not limited to, registers, flash memories, or combinations thereof, and is configured to store data. In one embodiment, the storage element 104 is configured to store the application program 130. The processing element 108 accesses the storage element 104 to execute the application program 130 to perform application processing on the weight measured by the weighing device 102. The alarm element 106 can include, for example, but not limited to, a buzzer, a light-emitting element, or a combination thereof, to generate alarm information in the form of sound, flash, or a combination thereof under the control of the processing element 108, or notify medical staff to handle through the communication element 110.
[0050] In one embodiment, the weighing device 102 further includes a gravity sensor 1021 for sensing the motion data of the weighing device 102. In one embodiment, to avoid the weighing device 102 performing calibration under abnormal conditions. For example, the weighing device 102 is in a skewed or lying flat state, or the weighing device 102 is in a moving or shaking state, resulting in inaccurate calibration weight at the moment and causing calibration weight failure. Therefore, in this case, when performing the calibration of the weighing device 102, the motion data of the weighing device 102 will be first judged by the gravity sensor 1021 to be within the set calibration orientation before calibration. In one embodiment, this calibration orientation is the orientation in which the hook of the weighing device 102 for hanging the drip bag or drip bottle is perpendicular to the ground. Accordingly, when the weighing device 102 is performing calibration, the processing element 108 will first read the value of the motion data detected by the gravity sensor 1021 and judge whether this motion data value is within this calibration orientation. If it is within this calibration orientation, the processing element 108 performs zero calibration on the weighing device 102. On the contrary, if it is not within this calibration orientation, that is, the hook is not perpendicular to the ground, the processing element 108 prohibits the weighing device 102 from performing zero calibration and notifies relevant personnel for handling. The gravity sensor 1021 can be an accelerometer (G-Sensor), a magnetometer (M-Sensor), a gyroscope (Gyroscope), a gravity sensor (GV-Sensor), a linear acceleration sensor (LA-Sensor), a rotation vector sensor (RV-Sensor), an inclination sensor (Tilt-Sensor), or an assembly of the above devices. Among them, the gravity sensor 1021 directly provides three-axis sensing signals, namely the X-axis acceleration (velocity) parameter, the Y-axis acceleration (velocity) parameter, and the Z-axis acceleration (velocity) parameter. In this embodiment, a three-axis inertial sensor is used for detection. In another preferred embodiment, a six-axis inertial sensor can be used for detection, where the three-axis acceleration is used for detection, and the other three-axis angular acceleration is used for verification to increase the reliability of the detection result. However, this case does not exclude the use of, for example, only nine-axis, nine-axis or more, or other similar means to detect the motion data.
[0051] In another embodiment, the patient during infusion does not interrupt the infusion, so when moving, the patient will move together with the drip monitoring system 100 hanging with the drip bag or drip bottle. To detect the moving position of the patient in the medical institution, the weighing device 102 of this case further includes a positioning element 1022 for positioning through the positioning element 1022. Figure 2Shown is a positioning system diagram according to an embodiment of this case, used to position the drip monitoring system 100 in a medical institution. In one embodiment, this positioning element 1022 can be a Wi-Fi, Bluetooth, Ultra-wideband (UWB), or ZigBee signal transmission element. And in a preferred embodiment, if the positioning element 1022 used is a Bluetooth signal transmission element, for positioning, multiple signal receivers 200, such as Bluetooth signal receivers, will be set at different positions in the medical institution. Each positioning element 1022 of each drip monitoring system 100 has its own identification code. The positioning element 1022 can periodically broadcast its identification code as a signal, such as a Bluetooth signal, so that the signal receivers 200 within its communication range can detect the presence of the positioning element 1022. The signal receiver 200 can detect and receive signals from the positioning element 1022, such as Bluetooth signals, within its effective communication range. When the signal receiver 200 detects the Bluetooth signal of the positioning element 1022 and receives the identification code in the Bluetooth signal, it will report the identification code to the cloud server 210. When the cloud server 210 receives the reported information, it can determine which positioning element 1022 of the drip monitoring system 100 sent it based on the identification code, and locate the position of this drip monitoring system 100 in this medical institution based on the position of the signal receiver 200 that reported the identification code to the cloud server 210. It should be noted that the above positioning method is only one embodiment and is not used to limit the implementation of this case. Other existing well-known positioning methods can also be used in this case to position the drip monitoring system 100. In one embodiment, the cloud server 210 can be the medical care platform of the medical institution.
[0052] In yet another embodiment, since the weighing device 102 of this case further includes a gravity sensor 1021, the positioning element 1022 can not only broadcast its identification code via a Bluetooth signal, but also broadcast the real-time motion data detected by the gravity sensor 1021 via a Bluetooth signal simultaneously. Among them, the gravity sensor 1021 can sense motion data such as the acceleration, angular acceleration, direction, and movement amount of the carrier, that is, the drip bag or drip bottle. The real-time usage status of the drip bag or drip bottle is identified through the above-mentioned motion data, and whether the patient's posture is likely to fall is indirectly judged. In one embodiment, since the drip bag or drip bottle is used to infuse the patient in a manner perpendicular to the ground, when there is an abnormal pulling condition or an incorrect infusion angle during the infusion process of the patient, there may be a danger in the drip administration. Therefore, in this case, the positioning element 1022 further broadcasts the real-time motion data detected by the gravity sensor 1021. When a signal receiver, such as the signal receiver 200, detects the Bluetooth signal of the positioning element 1022, in addition to reporting the identification code to the cloud server 210, it also reports the motion data to the cloud server 210. The cloud server 210 can then determine whether the drip bag or drip bottle in the corresponding drip monitoring system 100 is in an abnormal usage state based on this identification code and the motion data. In one embodiment, when the patient moves while carrying the drip bag or drip bottle, a falling event of the drip bag or drip bottle may occur once the patient falls. Therefore, when the real-time motion data detected by the gravity sensor 1021 shows that a falling event of the drip bag or drip bottle is occurring, it can be indirectly inferred whether a falling event has occurred in the patient's posture state, and the medical staff can be notified to go and handle it. In one embodiment, it is possible to determine whether the drip bag or drip bottle is in an abnormal usage state based on the change condition of the motion data sensed by the gravity sensor 1021 within a short time interval, such as a time interval of 2 - 3 seconds. It should be noted that other determination methods can also be used in this case.
[0053] Figure 3 The following shows a drip monitoring method capable of automatic calibration according to an embodiment of this case. Please also refer to Figure 1 and Figure 3 . The drip monitoring method 300 capable of automatic calibration can be applied to Figure 1 the drip monitoring system 100, and is executed after the processing element 108 extracts the application program 130 in the storage element 104. The drip monitoring method 300 includes the following steps (it should be understood that the steps mentioned in this embodiment, unless specifically stated for their order, can be adjusted in their front and back order according to actual needs, and can even be executed simultaneously or partially simultaneously).
[0054] In step 301, a start monitoring signal is received. In one embodiment, the start monitoring signal can be generated by a user touching a physical or virtual button included in the operation interface of the drip monitoring system 100 to control the processing element 108 to start the monitoring process.
[0055] In step 302, the current load weight and the motion data value are measured. In one embodiment, the processing element 108 controls the weighing device 102 to measure the current load weight and the motion data. For example, when a drip bag or a drip bottle containing drip liquid is hung on the weighing device 102, the weight of the hung drip bag or drip bottle is measured, and the motion data of the current weighing device is measured to judge the current condition of the drip bag or the drip bottle based on this motion data.
[0056] In step 303, it is judged whether the load weight is less than the warning weight. In one embodiment, the processing element 108 judges whether the weight of the hung drip bag or drip bottle is less than the warning weight according to the load weight measured by the weighing device 102. In one embodiment, when the drip liquid in the drip bag or the drip bottle continuously outputs, the load weight measured by the weighing device 102 will continuously decrease. Therefore, a warning weight is set to judge whether the drip liquid in the drip bag or the drip bottle has reached the lower limit. In one embodiment, the warning weight is the weight of the drip bag or the drip bottle plus the empty drip tube and the drip liquid at the lower limit. The value of the warning weight can be stored in the storage element 104 for the processing element 108 to extract and make the above judgment. When the load weight is not less than the warning weight, step 304 is executed to continue the monitoring state, and in step 305, after waiting for an interval time, the processing element 108 monitors again whether the current load weight measured by the weighing device 102 is less than the warning weight.
[0057] On the contrary, when the load weight is less than the warning weight, step 306 is executed to judge whether the load weight is less than the empty weight. In one embodiment, the empty weight is the weight when no drip bag or drip bottle is hung on the weighing device 102. Since the weighing device 102 may measure a non-zero load weight due to the deformation caused by hanging the drip bag or drip bottle for a long time when no drip bag or drip bottle is hung. Therefore, in this case, the empty weight is set according to the possible deformation, and usually the set empty weight is greater than zero. Accordingly, when the load weight is less than the empty weight, the processing element 108 will still judge that it is in the empty state. The value of the empty weight can be stored in the storage element 104 for the processing element 108 to extract and make the above judgment.
[0058] In step 306, when the current load weight is not less than the empty weight, the processing element 108 will determine that it is not in the empty state at this time. That is, there is still a drip bag or drip bottle hanging on the weighing device 102. And because the load weight at this time is less than the warning weight but greater than the empty weight. Therefore, in step 307, an alarm signal is issued. In one embodiment, the processing element 108 will control the alarm element 106 to issue an alarm signal to notify the medical staff to replace the drip bottle or drip bag.
[0059] In step 306, when the current load weight is less than the empty weight, that is, there is no drip bag or drip bottle hanging on the weighing device 102. Therefore, in step 308, the processing element 108 will determine that it is in the empty state at this time. Enter the zero calibration program of the weighing device 102.
[0060] To avoid the weighing device 102 performing the calibration program in an abnormal state. Therefore, before executing the zero calibration program of the weighing device 102, in step 309, it is judged whether the weighing device 102 can perform calibration, that is, whether the motion data of the weighing device is within the set calibration orientation. In one embodiment, the set calibration orientation is the orientation in which the hook of the weighing device 102 is perpendicular to the ground. In one embodiment, the gravity sensor 1021 in the weighing device 102 senses the motion data of the weighing device 102, and the processing element 108 reads the motion data value detected by the gravity sensor 1021 to judge whether this motion data value is within this calibration orientation. If it is within this calibration orientation, in step 310, the processing element 108 performs zero calibration on the weighing device 102. On the contrary, if it is not within this calibration orientation, that is, the hook is not perpendicular to the ground, the processing element 108 prohibits the weighing device 102 from performing zero calibration, notifies the relevant personnel, and in step 305, after waiting for the interval time, the processing element 108 monitors again whether the currently measured load weight of the weighing device 102 is less than the warning weight.
[0061] Figure 4 The following shows the manual calibration flowchart according to an embodiment of this case. Please also refer to Figure 1 and Figure 4Manual calibration process 400. At step 401, a calibration execution signal is received. In one embodiment, the calibration execution signal is generated by a user touching a physical or virtual button included in the operation interface of the drip monitoring system 100 to control the processing element 108 to start the calibration process. To avoid the weighing device 102 performing the calibration program in an abnormal state. Therefore, before executing the zero calibration program of the weighing device 102, at step 402, it is determined whether the weighing device 102 can execute the calibration program. In one embodiment, the calibration orientation is the orientation in which the hook of the weighing device 102 is perpendicular to the ground. The processing element 108 reads the motion data value detected by the gravity sensor 1021 in the weighing device 102 to determine whether the hook of the weighing device 102 is perpendicular to the ground. If so, at step 403, the processing element 108 performs zero calibration on the weighing device 102. On the contrary, if it is not within this calibration orientation, that is, the hook is not perpendicular to the ground, at step 404, the processing element 108 prohibits the weighing device 102 from performing zero calibration, and at step 405, a calibration not executed prompt is displayed. In one embodiment, it can be displayed through the display interface of the drip monitoring system 100.
[0062] Figure 5 The following is a flowchart of a method for positioning and monitoring the real-time status of a drip bottle or drip bag according to an embodiment of the present case. Please also refer to Figure 1 and Figure 5 . It should be noted that in this case, before the weighing device 102 performs zero calibration, the real-time status of the drip bottle or drip bag is continuously monitored.
[0063] Positioning and monitoring the real-time status of a drip bottle or drip bag 500. First, at step 501, the current load weight and motion data value are measured. In one embodiment, the processing element 108 controls the weighing device 102 to measure the current load weight and the motion data value of the weighing device 102. For example, when a drip bag or drip bottle filled with drip liquid is mounted on the weighing device 102, the weight of the mounted drip bag or drip bottle is measured, and the current motion data of the weighing device is measured to judge the real-time status of the drip bag or drip bottle based on this motion data. At step 502, it is judged whether the load weight is greater than the empty weight. When the current load weight is less than the empty weight, that is, there is no drip bag or drip bottle mounted on the weighing device 102. The processing element 108 will judge that the weighing device 102 is in an empty state at this time. Therefore, at step 503, the zero calibration program of the weighing device 102 is entered.
[0064] Next, in step 505, it is calculated whether the motion data is normal. In one embodiment, the processing element 108 reads the motion data detected by the gravity sensor 1021 in the weighing device 102, and broadcasts its identification code and the motion data value as a Bluetooth signal through the positioning element 1022, so that the signal receiver 200 within its communication range can receive the Bluetooth signal of the positioning element 1022 to read the identification code and the motion data value therein to determine the position. In one embodiment, the present case further calculates the acceleration changes of the motion data sensed by the gravity sensor 1021 in the X-axis, Y-axis, and Z-axis within a short time interval to determine the immediate usage status of the drip bottle or drip bag.
[0065] In step 505, if the calculated motion data is abnormal. Then in step 506, a warning message is generated. In one embodiment, a warning message for the abnormal condition of the drip bottle or drip bag is generated. In one embodiment, when the drip bottle or drip bag drops, it will cause instantaneous changes in the motion data such as the acceleration of the X-axis, Y-axis, and Z-axis, so that the change exceeds the set threshold value, and a warning message for the abnormal condition of the drip bottle or drip bag is generated in step 506. On the contrary, in step 505, if the calculated motion data is normal. For example, if the change does not exceed the set threshold value, it is determined that the drip bottle or drip bag is in a normal usage condition. Then in step 507, the rotation angle orientation in the motion data is read, and in step 508, it is transmitted to the cloud server. In one embodiment, the cloud server 210 can indirectly judge the traveling orientation and position of the patient or the device according to the rotation angle orientation.
[0066] And in step 509, it returns to the monitoring state. In step 510, after an interval of time, the processing element reads the bearing weight measured by the weighing device again.
[0067] In summary, in the present case, by setting a gravity sensor on the weighing device to sense the motion data of the weighing device, the current orientation of the weighing device is judged by this motion data, and whether to execute the zero calibration process is determined according to this orientation, thereby eliminating the disadvantage of performing zero calibration on the weighing device in an abnormal orientation. Furthermore, positioning can be performed according to the real-time motion data and its change amount, and whether an accident occurs can be judged.
[0068] Although the present case is disclosed as above with embodiments, it is not intended to limit the present case. Any person skilled in this art can make various modifications and refinements without departing from the spirit and scope of the present case. Therefore, the protection scope of the present case shall be subject to that defined by the scope of the patent application.
