[0018] Detailed Description of the Invention

[0019] Referring to Figure 1 , the infusion system 1 includes an infusion server 100, at least one identification information reader 200, at least one infusion pump 300, and at least one user terminal 400 (e.g., a mobile device, a laptop computer, a desktop computer, etc.). The infusion server 100 includes a first communication unit 110, a storage unit 120, a second communication unit 130, and a server processing unit 140. The first communication unit 110 is used to receive a medical order (DO), which records the patient's medical order infusion parameters (POD). The storage unit 120 is used to store the medical order (DO). The server processing unit 140 is electrically connected to the first communication unit 110, the storage unit 120, and the second communication unit 130. The server processing unit 140 is configured to: (1) obtain a medical order infusion parameter POD of the medical order OD; (2) transmit the medical order infusion parameter POD to the infusion pump 300 via the second communication unit 130; (3) receive a pump infusion parameter PP transmitted by the infusion pump 300 via the second communication unit 130; (4) respond to a pump infusion parameter adjustment signal SP transmitted by the infusion pump 300 and compare the adjusted pump infusion parameter PP of the infusion pump 300 with the medical order infusion parameter POD; (5) when the adjusted pump infusion parameter PP is inconsistent with the medical order infusion parameter POD, issue an alarm signal SW to at least one user terminal 400; and (6) respond to a confirmation signal SC transmitted by the user terminal 400 to release the alarm signal SW. In this way, when the infusion pump 300 is adjusted, the user can receive a real-time notification without having to frequently confirm the status of the infusion pump 300.

[0020] Examples of communication units herein include Bluetooth, fifth-generation mobile communication technology (5G), and Wi-Fi communication technology. Examples of processing units herein include physical circuits (e.g., chips, packages, etc.) formed using semiconductor processes, specifically processors, controllers, etc. Examples of storage units herein include memory.

[0021] In addition to the infusion order parameters POD, the medical order OD may also include the patient's infusion pump identification information R1, patient identification information R2, infusion drug identification information R3, user (medical staff, such as doctors, nurses, and nursing assistants) identification information R4, and bed number. The infusion order parameters POD include the infusion rate SPOD and the target output volume MLT of the drug solution ML for the patient. The infusion rate SPOD is, for example, a single value or a range of values.

[0022] The identification information reader 200 can read an identification information, and the server processing unit 140 can search for a medical order OD that matches the read identification information from multiple medical order ODs. For example, the identification information reader 200 can obtain infusion pump identification information R1, patient identification information R2, infusion drug identification information R3, and / or user identification information R4. The server processing unit 140 is also configured to: receive identification information R1-R4 transmitted by the identification information reader 200; and search for a medical order OD that matches identification information R1-R4 from multiple medical order ODs. In addition, the hospital information system 10 can store multiple medical order ODs. The server processing unit 140 can download the medical order ODs from the hospital information system 10 and store them in the storage unit 120. In this way, the server processing unit 140 can select a medical order OD that matches the identification information from the multiple medical order ODs in the storage unit 120. Compared to the server processing unit 140 searching for a medical order OD matching the identification information R1-R4 from the multiple medical order ODs stored in the hospital information system 10, searching for a medical order OD matching the identification information R1-R4 from the multiple medical order ODs stored in the storage unit 120 is faster and more efficient. Furthermore, the server processing unit 140 can periodically download the latest medical order OD from the hospital information system 10. Alternatively, upon receiving the identification information transmitted by the identification information reader 200, the server processing unit 140 downloads the latest medical order OD from the hospital information system 10 and then selects a medical order OD matching the identification information from the latest multiple medical order ODs.

[0023] The identification information reader 200 is, for example, a barcode reader that can scan a barcode and obtain the identification information therein (e.g., including numbers, text, symbols, or a combination thereof). In another embodiment, the identification information reader 200 may include a camera and a processor. The camera captures an image of the barcode, and the processor analyzes the image to obtain the barcode's identification information. In one embodiment, the identification information reader 200 may be configured on a user terminal 400, and the user terminal 400 reads the identification information. Step S230: Utilize an object detection algorithm to obtain a plurality of second contours and a plurality of second center coordinates of the reference pattern in the second image.

[0024] In addition, the pump infusion parameter PP is, for example, the current pump infusion speed SPCP and the current total output volume ML1 of the infusion pump 300. The infusion pump 300 can periodically transmit the pump infusion parameter PP to the infusion server 100. The infusion pump 300 is connected to a drug 20, which contains a liquid medicine ML. The infusion pump 300 can output the liquid medicine ML to the patient. The infusion pump 300 includes a pump communication unit 310, a pump processing unit 320 and a motor 330. The pump communication unit 310 can use wireless communication technology to transmit information of the infusion pump 300 (for example, the pump infusion parameter PP) to the server processing unit 140 of the infusion server 100. The type of the pump communication unit 310 is the same as the aforementioned second communication unit 130.

[0025] The pump processing unit 320 is electrically coupled to the pump communication unit 310 and the motor 330 and is configured to control the motor 330 to operate at a certain speed based on the physician's order infusion parameter POD. The pump processing unit 320 obtains the total output volume ML1 of the liquid medicine ML in the drug 20 based on the operating time and speed of the motor 330. The pump processing unit 320 can obtain the remaining output volume ML2 (i.e., ML2 = MLT - ML1) that has not yet been delivered to the patient based on the difference between the target output volume MLT and the total output volume ML1.

[0026] Please refer to Figure 2, which shows that when the pump infusion parameter PP (e.g., pump infusion rate SPCP) of the infusion pump 300 is adjusted, the infusion pump 300 can notify the infusion server 100. For example, in response to the user's pump infusion parameter adjustment instruction T3 to the infusion pump 300, the infusion pump 300 generates a pump infusion parameter adjustment signal SP and transmits it to the infusion server 100 to notify the infusion server 100 that the pump infusion parameter PP of the infusion pump 300 has been adjusted. The infusion server 100 then issues an alarm signal SW to the user terminal 400. Based on the alarm signal SW, the user interface U1 of the user terminal 400 displays (pops up) a confirmation button, which the user can trigger. In response to the user's trigger instruction, the user terminal 400 transmits a confirmation signal SC to the infusion server 100, which in turn releases the alarm signal SW. If the user does not trigger the confirmation button, the infusion server 100 continues to issue the alarm signal SW. In addition, the aforementioned method of adjusting the pump infusion parameter PP of the infusion pump 300 is, for example, achieved by the user operating the user interface on the infusion pump 300 or the user interface U1 of the user terminal 400 .

[0027] Please refer to Figure 3, which shows a functional block diagram of the infusion system 1 after the medical order OD has been modified. A user can modify the medical order OD (referred to as medical order OD' after modification) via the user terminal 400. After the medical order OD is modified, the user terminal 400 can send a medical order infusion parameter modification signal SD to the infusion server 100. The server processing unit 140 is further configured to: respond to the medical order infusion parameter modification signal SD for modifying a medical order infusion parameter POD (referred to as medical order infusion parameter P'OD after modification), compare the modified medical order infusion parameter P'OD with the pump infusion parameter PP; and, if the modified medical order infusion parameter P'OD is inconsistent with the pump infusion parameter PP, issue an alarm signal SW to the user terminal 400. In one embodiment, a user can modify the medical order OD via one user terminal 400 (e.g., a doctor's user terminal), and the alarm signal SW can be sent to another user terminal 400 (e.g., a nurse's user terminal). Based on the alarm signal SW, the user interface U1 of the user terminal 400 (e.g., a nurse's user terminal) displays (pops up) a confirmation button. When the user activates the confirmation button, the user terminal 400 transmits a confirmation signal SC to the infusion server 100, thereby resetting the alarm signal SW. If the user does not activate the confirmation button, the infusion server 100 continues to emit the alarm signal SW.

[0028] Furthermore, when a user modifies the medical order OD stored in the storage unit 120, the modified medical order OD' can be overwritten with the same medical order OD stored in the hospital information system 10. In other embodiments, the infusion server 100 can also directly modify the medical order OD stored in the hospital information system 10. Furthermore, before modifying the medical order OD, the infusion server 100 can first perform identity verification, and only after successful identity verification can the user be allowed to modify the medical order OD.

[0029] 4 , when the infusion pump 300 stops infusion (e.g., a patient needs to stop infusion for an examination), the infusion pump 300 can record the remaining output volume ML2 and the pump infusion speed SPCP of the infusion pump 300 when the infusion stops, and notify the infusion server 100. Specifically, the infusion pump 300 responds to a stop infusion instruction T1, records the remaining output volume ML2 and the pump infusion speed SPCP of the infusion pump 300 when the infusion stops, and transmits the information of the remaining output volume ML2 and the pump infusion speed SPCP to the infusion server 100. In one embodiment, the operation of the infusion pump 300 is stopped by the user operating the user interface on the infusion pump 300 or the user interface U1 of the user terminal 400. The aforementioned stop infusion instruction T1 can be generated through the user interface (based on the user's operation). After the stop infusion instruction T1 is generated, it can be transmitted to the infusion server 100.

[0030] In addition, after the infusion pump 300 stops infusion, the user can continue the infusion through the infusion pump 300 or the user terminal 400. Further, when the infusion pump 300 stops infusion, the infusion server 100 responds to the stop infusion instruction T1 and transmits the resume infusion signal SM to the user terminal 400. The user interface U1 of the user terminal 400 displays (or pops up) a resume infusion button based on the resume infusion signal SM, waiting for the user to trigger it to continue the infusion. The user can trigger the resume infusion button (resume infusion instruction T2), and the user interface U1 transmits this resume infusion instruction T2 to the infusion server 100. The infusion server 100 responds to the resume infusion instruction T2 transmitted by the user terminal 400 and controls the infusion pump 300 to continue the infusion. In one embodiment, the infusion pump 300 continues the infusion at the recorded current pump infusion speed SPCP. In this way, the infusion pump 300 or the infusion server 100 does not need to additionally query the doctor's order OD.

[0031] In summary, when the physician order infusion parameter POD of the physician order OD is modified and / or the pump infusion parameter PP of the infusion pump 300 is adjusted, the infusion server 100 notifies the user terminal 400 accordingly. The user receives the aforementioned physician order modification or pump parameter adjustment information through the user terminal 400 and optionally deactivates the alarm signal SW through the user terminal 400. Alternatively, the user may reconfirm whether the physician order infusion parameter POD and / or pump infusion parameter PP are correct before deciding whether to deactivate the alarm signal SW. In one embodiment, the infusion server 100 may control the infusion pump 300 to pause the infusion while notifying the user terminal 400. After the alarm signal SW is deactivated, the infusion pump 300 may be controlled to resume the infusion.

[0032] Please refer to Figure 5, which shows a schematic diagram of an infusion system 2 of another embodiment. The infusion system 2 includes the same or similar technical features as the infusion system 1, except that the infusion system 2 also includes a physiological information sensor 500. The physiological information sensor 500 can be worn on the patient normally, or worn on the patient when sensing is required. The physiological information sensor 500 can sense the patient's physiological information DR2 (for example, blood pressure, blood oxygen, electrocardiogram, heart rate, etc.). The server processing unit 140 is also used to: (1) respond to the patient's physiological information DR2 transmitted by the physiological information sensor 500, and obtain the medical order infusion parameter POD corresponding to the physiological information DR2 from the medical order OD; and (2) control the infusion pump 300 to perform infusion with the obtained medical order infusion parameter POD.

[0033] The infusion server 10 includes a correspondence between the doctor's order infusion parameter and the physiological information (for example, a table, a curve, or an equation, etc.). The server processing unit 140 can obtain the doctor's order infusion parameter POD corresponding to the physiological information DR2 from this correspondence. The aforementioned correspondence can be stored in the storage unit 120 or recorded in the doctor's order OD. When the doctor's order infusion parameter POD corresponding to the physiological information DR2 does not match the pump infusion parameter PP of the infusion pump 300, the server processing unit 140 can automatically adjust the pump infusion parameter PP of the infusion pump 300 so that the adjusted pump infusion parameter PP meets the correspondence. In this way, the server processing unit 140 can automatically adjust the pump infusion parameter PP in real time based on the current physiological information DR2, which can reduce the burden on the user.

[0034] Furthermore, when the physician-ordered infusion parameter POD corresponding to the physiological information DR2 does not match the pump infusion parameter PP of the infusion pump 300, the server processing unit 140 may issue an alarm signal SW to the user terminal 400 to notify the user terminal 400. In other embodiments, the physiological information sensor 500 may periodically sense the patient's physiological information DR2 and transmit the current (latest) physiological information DR2 to the server processing unit 140.

[0035] Please refer to FIG. 6 , which shows a flow chart of an infusion method according to an embodiment of the present invention, and also refer to FIG. 1 and FIG. 2 .

[0036] In step S110, the server processing unit 140 receives the identification information transmitted by the identification information reader 200; in step S112, the server processing unit 140 selects a medical order OD that meets the identification information from a number of medical order ODs; in step S114, the server processing unit 140 of the infusion server 100 receives the medical order OD through the first communication unit 110, wherein the medical order OD records the patient's medical order infusion parameter POD; in step S116, the storage unit 120 stores the medical order OD; in step S118, the server processing unit 140 obtains the medical order infusion parameter POD of the medical order OD; in step S120, the server processing unit 140 transmits the medical order infusion parameter POD to the infusion pump 300 through the second communication unit 130; in step S122, the server processing unit 140 receives the pump infusion parameter PP transmitted by the infusion pump 300 through the second communication unit 130.

[0037] In step S124, the server processing unit 140 compares the adjusted pump infusion parameter PP of the infusion pump 300 with the physician-ordered infusion parameter POD in response to the pump infusion parameter adjustment signal SP transmitted by the infusion pump 300. When the pump infusion parameter PP of the infusion pump 300 is adjusted, the infusion pump 300 may transmit the pump infusion parameter adjustment signal SP to the infusion server 100, and the server processing unit 140 compares the adjusted pump infusion parameter PP with the physician-ordered infusion parameter POD.

[0038] In step S126, the server processing unit 140 determines whether the adjusted pump infusion parameter PP is consistent with the physician-ordered infusion parameter POD. If the adjusted pump infusion parameter PP is consistent with the physician-ordered infusion parameter POD, the process proceeds to step S128. If the adjusted pump infusion parameter PP is inconsistent with the physician-ordered infusion parameter POD, the process proceeds to step S130.

[0039] In step S128 , the server processing unit 140 does not send an alarm signal SW. In step S130 , the server processing unit 140 sends an alarm signal SW to the user terminal 400 . In step S132 , the alarm signal SW is released in response to the confirmation signal SC sent by the user terminal 400 .

[0040] In another embodiment, when the medical order OD is modified, the infusion server 100 may also send an alarm signal SW, which is illustrated below with reference to FIG. 7 and FIG. 3 .

[0041] In step S210, the server processing unit 140 responds to the medical order infusion parameter modification signal SD and compares the modified medical order infusion parameter POD with the pump infusion parameter PP; in step S212, the server processing unit 140 determines whether the modified medical order infusion parameter POD is consistent with the pump infusion parameter PP. If the modified medical order infusion parameter POD is consistent with the pump infusion parameter PP, the process enters step S214; if the modified medical order infusion parameter POD is inconsistent with the pump infusion parameter PP, the process enters step S216; in step S214, the server processing unit 140 does not issue an alarm signal SW; in step S216, based on the inconsistency between the modified medical order infusion parameter POD and the pump infusion parameter PP, the server processing unit 140 issues an alarm signal SW to the user terminal 400; in step S218, in response to the confirmation signal SC transmitted by the user terminal 400, the server processing unit 140 releases the alarm signal SW.

[0042] In another embodiment, when the infusion pump 300 stops infusing, the infusion server 100 may also send an alarm signal SW, which is illustrated below with reference to FIG. 8 and FIG. 4 .

[0043] In step S310, when a patient needs to pause their infusion for a medical examination, the user can stop the infusion pump 300. In response to this stop infusion instruction T1, the infusion pump 300 records the remaining output volume ML2 of the liquid ML in the medication 20 and the pump infusion speed SPCP at the time the infusion pump 300 stopped infusion. In step S312, the infusion pump 300 transmits the remaining output volume ML2 and the pump infusion speed SPCP to the infusion server 100. In step S314, the server processing unit 140 transmits a resume infusion signal SM to the user terminal 400. In step S316, in response to the resume infusion instruction T2 transmitted by the user terminal 400, the server processing unit 140 controls the infusion pump 300 to resume the infusion. In one embodiment, the infusion pump 300 resumes the infusion at the recorded pump infusion speed SPCP. This eliminates the need for the infusion pump 300 or the infusion server 100 to query the doctor's order (OD).

[0044] In summary, embodiments of the present invention provide an infusion system. When a medical order is modified, the parameters of an infusion pump are adjusted, and / or the infusion pump stops operating, the infusion server can notify medical staff in real time, eliminating the need to frequently confirm the status of the infusion pump. In another embodiment, medical staff can remotely modify medical orders, adjust infusion pump parameters, and / or stop the infusion pump without requiring on-site operation, thereby reducing their burden.
