[0025] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application. Without conflict, the following embodiments and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0026] Embodiment 1

[0027] Referring to the attached Figure 1-2 , this embodiment provides a disposable multi-channel analgesia pump, which includes: a multi-channel analgesia pump main body, a microfluidic liquid delivery system, a disposable multi-channel liquid injection system, a wireless communication module, and a remote control terminal.

[0028] According to an embodiment of the present application, an integrated control logic circuit is provided in the multi-channel analgesia pump main body, and the control logic circuit includes: a microprocessor unit, a logic judgment module, a power drive module, and a status detection and feedback module; an integrated microfluidic chip is integrated in the microfluidic liquid delivery system to ensure the precise quantitative infusion of the liquid in the multi-channel liquid injection system; the control logic circuit and the microfluidic liquid delivery system are respectively connected to the remote control terminal through a wireless communication module for network connection.

[0029] According to an embodiment of the present application, the microprocessor unit is used to process control instructions sent from a remote control terminal, physiological parameter data collected by a physiological parameter monitoring module, and output signals sent from an integrated microfluidic chip, and generate output instructions for dynamically controlling each channel liquid medicine injection unit; the logic judgment module is used to implement dynamic control of each channel liquid medicine injection unit through preset priority judgment conditions; the power supply driving module is used to respond to the output instructions sent by the microprocessor unit, perform power distribution on each channel liquid medicine injection unit, so as to ensure that only one channel liquid medicine injection unit is turned on at any moment; the status detection and feedback module is used to monitor the working status, current, voltage and fault information of each channel liquid medicine injection unit, obtain the monitoring results of each channel liquid medicine injection unit, and send the monitoring results to the remote control terminal to achieve closed-loop control and automatic alarm.

[0030] Further, the microprocessor unit, as the core of the entire control logic circuit, is responsible for receiving and processing various data information from the remote control terminal, physiological parameter monitoring module and integrated microfluidic chip; when the wireless communication module receives a remote instruction from the remote control terminal, such as start, adjust dose, pause operation, etc., the microprocessor unit parses it, and combines it with the real-time collected physiological parameter data for comprehensive judgment. Based on the preset analgesia strategy and logic judgment result, the microprocessor unit generates control information and transmits it to the power supply driving module to adjust the working status of each channel. At the same time, the processed data, operation status and abnormal conditions are fed back to the status detection and feedback module in real time, and reported to the remote control terminal through the wireless communication module to achieve remote monitoring and data recording.

[0031] Further, in combination with the current status information of each channel provided by the microprocessor unit, such as current, voltage, working status, the logic judgment module first confirms the channel that is currently in the working state and monitors it. When it is necessary to switch channels, for example, from patient self-control to remote control, or adjust the dose according to physiological data, this module automatically judges and generates a switching scheme according to the preset priority judgment conditions, such as the self-control channel and the remote control channel work alternately, and sends the judgment result as an instruction to the power supply driving module to ensure that the principle of "one-channel power supply" is strictly followed during the execution process, preventing multiple channels from being powered at the same time, thereby avoiding the risks of liquid medicine mixing and misoperation.

[0032] Furthermore, the power drive module internally integrates high-speed electronic switches such as relays to quickly switch the circuit state according to control instructions. During the power distribution process, it monitors the changes in current and voltage in real time. If abnormalities such as excessive current or instantaneous voltage fluctuations are detected, it immediately cuts off the power to avoid circuit overload and equipment damage. The module is designed with a low-delay circuit to ensure that the power supply can be switched within milliseconds when a channel state change is detected, meeting the time requirement for drug release in clinical emergencies.

[0033] Furthermore, the state detection and feedback module is built-in with multiple sensors such as current sensors, voltage sensors, and temperature sensors to collect the working parameters of each channel in real time. When the monitored parameters exceed the preset safety range, the module automatically generates a fault signal and triggers a safety power-off procedure. At the same time, it sends an alarm message to the remote control terminal through the wireless communication module. All detection data and alarm records are saved to the local memory in real time and uploaded to the remote control terminal regularly for post-event data analysis and equipment maintenance.

[0034] According to an embodiment of the present application, the disposable multi-channel drug injection system involved in the present application is provided with at least three channel drug injection units, namely the first channel drug injection unit, the second channel drug injection unit, and the third channel drug injection unit. Among them, the first channel drug injection unit is a patient-controlled analgesia channel with a personalized analgesic dose preset. The second channel drug injection unit is a remotely controlled analgesia channel for releasing rapid analgesic drugs by a physician sending control instructions through the central control system when the patient has acute pain. The third channel drug injection unit is used to infuse adjuvant drugs, and the infused adjuvant drugs are antiemetics or adjuvant analgesics.

[0035] According to an embodiment of the present application, the integrated microfluidic chip includes: a multi-channel microfluidic structure connected to the first channel drug injection unit, the second channel drug injection unit, or the third channel drug injection unit to achieve precise delivery of the drug solution in each channel drug injection unit; an embedded micro-valve device for precisely controlling the opening and closing states of each channel drug injection unit; and a micro-sensor for real-time monitoring of the flow rate and concentration of the drug solution and feedback sending the flow rate and concentration of the drug solution to the remote control terminal to achieve closed-loop regulation.

[0036] Furthermore, before production or leaving the factory, the system pre-sets the personalized analgesic dose of the first channel drug injection unit according to the patient's condition and the physician's plan. The dosing parameters of the second channel drug injection unit and the third channel drug injection unit are also pre-configured with the corresponding drug solution concentration and release rate. After the device is powered on, each channel in the microfluidic chip is in a closed state, and the embedded micro-valve is in an initial closed state to ensure that each drug solution does not flow before being triggered.

[0037] When the patient feels pain, the first-channel liquid medicine injection unit is started by triggering a button or gesture operation. The wireless communication module inside the system receives the patient's operation signal and transmits the signal to the remote control terminal. The remote control terminal instructs the power drive module to supply power to the first-channel liquid medicine injection unit, and at the same time the control logic starts the corresponding microfluidic chip channel. The embedded microvalve quickly opens according to the preset parameters, so that the liquid medicine is transported to the injection site in a precise quantitative manner in the preset flow channel. The micro sensor monitors the flow rate and concentration of the liquid medicine in real time and feeds the data back to the remote control terminal to ensure that the actual released dose is consistent with the preset dose and realize closed-loop regulation;

[0038] When the patient's acute pain condition is serious, the remote physician issues a start instruction through the mobile phone APP. The wireless communication module receives and transmits the instruction to the remote control terminal. According to the principle of "power supply for one channel and power off for other channels", the logic judgment module first confirms the current state of the first-channel liquid medicine injection unit, and then switches to the second-channel liquid medicine injection unit according to the priority instruction. The power drive module disconnects the power supply of the first-channel liquid medicine injection unit and allocates power to the second-channel liquid medicine injection unit; the embedded microvalve of the second-channel liquid medicine injection unit in the microfluidic chip immediately opens and delivers the analgesic drug according to the set high-concentration and rapid-release parameters; during this period, the micro sensor monitors the flow rate and concentration, and the remote control terminal makes real-time correction to ensure the accurate implementation of the remote physician's instruction. The real-time data during the whole process, including the power state, the liquid medicine release situation and the sensor feedback, is reported to the remote control terminal through the wireless communication module for the physician to remotely monitor;

[0039] In some cases, such as when the patient has nausea, vomiting or needs to enhance the analgesic effect, the system automatically or upon the physician's instruction starts the third-channel liquid medicine injection unit. The power drive module supplies power to the third-channel liquid medicine injection unit according to the instruction of the remote control terminal. At the same time, the auxiliary channel in the corresponding microfluidic chip is started, and the embedded microvalve opens precisely according to the preset scheme, and the auxiliary drug, such as the antiemetic drug, starts to be infused; the micro sensor continuously monitors the flow rate and concentration of the liquid medicine in this channel and feeds the information back to the remote control terminal. If there is a deviation between the monitored data and the expected parameters, the system will make automatic adjustment or send out an alarm signal.

[0040] According to an embodiment of the present application, the logic judgment module adopts an embedded algorithm to judge the working state of each channel liquid medicine injection unit according to the physiological parameter data, and based on the preset priority judgment conditions, generates an output instruction for precisely controlling the power drive module and sends it to the microprocessor unit to generate an output instruction for dynamically controlling each channel liquid medicine injection unit.

[0041] Furthermore, the logic judgment module adopts an embedded algorithm to judge the working states of each channel according to the real-time detection data, and through a preset priority track, such as preferentially ensuring the alternating work between the automatic control channel and the remote control channel, to achieve precise control of the power drive module and avoid the mixing of liquid medicines or accidental release caused by simultaneous power supply to multiple channels.

[0042] According to an embodiment of the present application, the status detection and feedback module further includes an overcurrent protection, undervoltage detection, and short-circuit detection circuit. When an abnormal electrical state of the liquid medicine injection unit of each channel is detected, a safety power-off mechanism is automatically triggered, and an alarm message is sent to the remote control terminal through the wireless communication module to ensure the safety of patients in case of a failure.

[0043] Furthermore, sensors are built into each channel to collect the current working state data in real time and transmit it to the microprocessor unit. The data includes whether each channel is currently in a powered state, the liquid medicine release flow rate, and electrical parameters; the embedded algorithm runs in the microprocessor to analyze the real-time collected data. The algorithm first compares the electrical states, liquid medicine release amounts, and historical working records of each channel to judge whether the current working channel is stable or needs to be switched. According to the preset priority track, the alternating work between the automatic control channel and the remote control channel is preferentially ensured; for example, after the automatic control channel is started, if the patient continuously uses it up to the set time or dose limit, the system automatically judges to switch to the remote control channel; or under a remote control instruction, when the system detects that the automatic control channel is in an inactive state, the remote control channel is started; if it is detected that the working state of a certain channel is unstable, such as large current fluctuations or large deviations in the liquid medicine release amount, the embedded algorithm immediately judges whether it is necessary to switch to another channel to ensure continuity and accuracy; based on the algorithm judgment result, a control signal is output to the power drive module to ensure that only one channel is powered, avoiding the mixing of liquid medicines or accidental release caused by the simultaneous activation of multiple channels.

[0044] After receiving the control instruction from the embedded algorithm, the power drive module responds quickly and executes according to the principle of "one channel is powered and other channels are powered off". When a switch is needed, the power supply of the current working channel is disconnected through a relay, and power is quickly allocated to the next priority channel. After the switch, the circuit state is detected again by the built-in sensor, and the embedded algorithm compares whether the new state is consistent with the preset parameters to ensure a successful and stable switch.

[0045] Integrated overcurrent detection circuit, which monitors the current values of each channel in real time. When the current exceeds the preset threshold, it is immediately judged as an overcurrent state. The voltage of each channel is monitored. If the voltage is lower than the set safety value, it is judged as an undervoltage state. Whether there is a low-impedance path, that is, a short-circuit phenomenon, in the detection circuit is detected, and whether there is a short-circuit risk is judged in real time; when any of the above detection circuits detects an abnormal electrical state such as overcurrent, undervoltage or short circuit, the state detection module immediately generates an abnormal signal. The abnormal signal is transmitted to the microprocessor unit, and the embedded algorithm immediately judges the severity of the abnormality and instructs the power drive module to quickly cut off the power of the current channel to prevent the accident from expanding. At the same time, the state detection module sends detailed alarm information, including the type of abnormality, the channel where it occurs and the timestamp, etc., to the remote control terminal such as the doctor's mobile phone APP or the cloud platform through the wireless communication module. The entire abnormal detection, power-off and alarm process is recorded and stored in the local log and regularly uploaded to the cloud platform for post-event analysis and maintenance.

[0046] According to an embodiment of the present application, the wireless communication module adopts end-to-end encryption technology to build a two-way data transmission channel to prevent the control logic circuit, the microfluidic liquid medicine delivery system and the remote control terminal from being stolen or tampered with during the data transmission process.

[0047] According to an embodiment of the present application, the physiological parameter monitoring module is used to collect the physiological parameter data of the patient. The physiological parameter data includes blood pressure data, heart rate data and oxygen saturation data, and sends the physiological parameter data to the remote control terminal and the microprocessor unit; the remote control terminal is one or more of a mobile phone APP, a computer software processing system, and a cloud platform, and is used to support functions such as remote monitoring, remote control, data interaction, early warning prompt and user operation log recording, and establishes a system follow-up channel through two-dimensional code technology to realize instant feedback and doctor's remote intervention.

[0048] Furthermore, after the analgesia pump is powered on, the wireless communication module is immediately started, automatically searches for and connects to the preset secure network. This module uses end-to-end encryption technology to establish a two-way data transmission channel between the mobile phone APP and the cloud platform to ensure that all transmitted data is encrypted, thus effectively preventing the data from being stolen or tampered with. After establishing the connection, the system completes the mutual identity confirmation through the handshake protocol to ensure the stability and security of the communication link; the built-in physiological parameter monitoring module collects the vital sign data of the patient such as blood pressure, heart rate, and oxygen saturation in real time through sensors. After preliminary analog processing, these data are transmitted to the wireless communication module in real time through encrypted communication. After receiving the data, the wireless communication module uploads it to the cloud platform through a pre-encrypted channel and sends a real-time data stream to the remote control terminal at the same time, facilitating medical staff to monitor the patient's state and intervene in a timely manner.

[0049] The mobile phone APP is built with a remote monitoring module that can display the physiological data and device status information uploaded from the analgesia pump in real time. Physicians or nursing staff can visually view the dynamic changes in the patient's blood pressure, heart rate, and oxygen saturation, and set warning parameters. When the data exceeds the safe range, the APP will automatically pop up a warning message; in addition to data monitoring, the APP also provides a remote control function. Physicians can send instructions through the APP, such as adjusting the analgesia dose, switching the working channel, or initiating an emergency drug administration procedure. These instructions are encrypted and transmitted through the wireless communication module to the control logic system inside the analgesia pump; at the same time, the APP records all user operation logs, including the instruction issuance time, specific operation content, and feedback information, ensuring that the entire operation process is traceable; for the convenience of patients and their families, the system supports quick access through QR codes. Patients only need to scan the QR code printed on the device with their mobile phones to automatically download and install the dedicated APP or directly enter the remote monitoring interface to achieve instant feedback and remote intervention.

[0050] According to an embodiment of the present application, it further includes a user identity authentication module and an edge computing unit; wherein, the user identity authentication module uses RFID and biometric technologies to perform dual identity verification on patients and physicians to ensure the legality and security of operation permissions; the edge computing unit is used to preprocess the physiological parameter data collected by the physiological parameter monitoring module and upload the preprocessed data to the cloud platform. The cloud platform receives and analyzes the preprocessed data using artificial intelligence algorithms to generate a personalized analgesia dose regulation strategy for physicians' reference and adjustment.

[0051] Furthermore, before the analgesia pump is started, the patient or physician needs to perform identity verification through the built-in RFID reader; the RFID tag is bound to the information pre-registered by the user. When the user brings the identity card close to the device, the RFID module reads the tag information and sends it to the control logic circuit for comparison. Only after the comparison is successful can the system allow the next operation, ensuring that only authorized users can access the device; in addition to RFID, the system also integrates a biometric module that can use fingerprint recognition, face recognition, or iris recognition technologies. The user needs to complete a biometric scan on the device or APP terminal. The scan result is encrypted and sent to the identity authentication module for matching with the template stored in the system. After successful matching, the identity authentication module feeds back the verification result to the control logic circuit to allow the user to perform subsequent operations; only when both RFID recognition and biometric recognition are successfully verified will the system consider the user's identity legal and activate subsequent operation permissions. In addition, the system will record the verification log during each operation and upload the log to the cloud platform to ensure that the operation history can be traced in subsequent security audits; if any identity verification link fails, the system will reject the user's operation, send a warning message to the remote control terminal through the wireless communication module, and trigger a local locking mechanism to prevent security risks caused by illegal multiple attempts.

[0052] According to an embodiment of the present application, it further includes a disposable encapsulation housing and a safety disposal module. The disposable multi-channel liquid medicine injection system, the control logic circuit, the microfluidic liquid medicine delivery system, and the wireless communication module are integrally encapsulated inside the multi-channel analgesic pump main body through the disposable encapsulation housing.

[0053] Furthermore, when the preset analgesic cycle is completed or when a system abnormality occurs, the control logic circuit triggers the automatic closing program of the safety disposal module. The disposable encapsulation housing and the internal control logic circuit, wireless communication module, and microfluidic liquid medicine delivery system form an integrated structure, which can completely enclose all internal modules to prevent secondary use. After being enclosed, the device enters the safety disposal state, and the internal liquid medicine and circuit are completely isolated to prevent leakage and accidental startup. At the same time, the device will automatically generate a sealing report and upload it to the cloud platform through the wireless communication module, providing necessary data information and tracking records for medical waste disposal. The disposable encapsulation material used in the design meets the environmental protection requirements for medical waste, ensuring that the sealed device can be safely sent to a dedicated disposal facility to meet the national medical waste management requirements.

[0054] Furthermore, the working principle of the disposable multi-channel analgesic pump provided by the present application is as follows: The physiological parameter monitoring module continuously collects data such as the patient's blood pressure, heart rate, and oxygen saturation, and securely and stably transmits them to the mobile phone APP, cloud platform, and remote control terminal through the end-to-end encrypted wireless communication module. The multi-channel analgesic pump main body integrates an integrated control logic circuit and a disposable microfluidic liquid medicine delivery system. The control logic circuit uses an embedded algorithm to judge the working state of each channel through a preset priority trajectory, dynamically controls the power drive module, and only allows one channel to be powered at any moment. The microfluidic chip is provided with multiple microchannels, embedded microvalves, and micro sensors to achieve precise quantitative infusion of the liquid medicine, and perform closed-loop monitoring and real-time feedback during the infusion process to ensure accurate and stable drug delivery. The edge computing unit preprocesses the collected physiological data and uploads it to the cloud platform in real time. The cloud platform generates a personalized analgesic dose regulation strategy with the help of artificial intelligence algorithms, providing a scientific decision-making basis for remote physicians. At the same time, the device is designed with a disposable encapsulation housing and a safety disposal module, which can completely enclose the internal system to prevent secondary use when the analgesic cycle is completed or an abnormal situation occurs, and meet the environmental protection disposal standards for medical waste.

[0057] According to an embodiment of the present application, it further includes a packaging shell, through which the control logic circuit, the microfluidic liquid medicine delivery system, and the wireless communication module are integrally packaged inside the multi-channel analgesic pump main body. At the same time, the non-disposable multi-channel liquid medicine injection system includes three liquid medicine storage bags and infusion tubes respectively connected thereto. The three liquid medicine storage bags are respectively connected to the multi-channel microchannel structure through pipelines, and are used to input the liquid medicine in the liquid medicine storage bags into the patient's body through the infusion tubes. It should be noted that the liquid medicine storage bags are arranged outside the packaging shell, and the two are independent structural designs.
