Description

Technical Field

[0001] This invention relates to the field of power control equipment technology, and in particular to an infusion pump system and its power management method and apparatus. Background Technology

[0002] With the development of the medical field, infusion pumps are being used in clinical infusions. Infusion pumps are becoming increasingly intelligent, capable of automatically controlling the infusion rate and volume, and have functions such as pipeline blockage alarm and air bubble alarm, which can greatly reduce the workload of medical staff.

[0003] In medical applications, infusion pumps have high requirements for quality and size, while also needing to meet certain endurance requirements. Infusion pumps typically consume a lot of energy, and their compact size and endurance performance are contradictory. Therefore, the power management requirements for infusion pumps are quite high.

[0004] Therefore, improvements can be made to save energy consumption of the infusion pump and extend its operating range. Summary of the Invention

[0005] This invention provides an infusion pump system and its power management method and apparatus, which can save energy consumption of the infusion pump and extend its operating range.

[0006] To achieve the above objectives, the present invention provides an infusion pump system, comprising:

[0007] Infusion pump body;

[0008] The memory is used to record the working modes of each component under different operating instructions;

[0009] The detection unit includes a variety of detection elements;

[0010] The processor, the detection unit being connected to the processor, the processor being configured to receive operation commands and control the operating modes of each of the detection elements and change the operating state of the infusion pump;

[0011] A power supply unit is connected to the processor. The power supply unit is used to selectively supply power to each of the detection elements of the detection unit according to the electrical signal issued by the processor, so that the corresponding detection element can collect detection data.

[0012] The present invention provides an infusion pump system in which the power supply unit selectively supplies power to each detection element of the detection unit according to the electrical signal issued by the processor, so that the corresponding detection element can collect detection data. Therefore, during the infusion interval, it is possible to choose not to supply power to some detection elements to achieve the effect of saving power and extending the endurance of the infusion pump.

[0013] In one possible implementation, the infusion pump system further includes:

[0014] An infusion unit is connected to the processor and is used to drive an infusion motor to rotate for infusion according to an electrical signal issued by the processor.

[0015] An interaction unit, connected to the processor, is used to receive operation instructions;

[0016] An alarm unit is connected to the processor and is used to issue warning information based on an electrical signal emitted by the processor.

[0017] In one possible implementation, the plurality of said detection elements includes at least:

[0018] A pressure detection device is used to detect whether the infusion tubing of the infusion unit is unobstructed;

[0019] A bubble detector is used to detect whether there are bubbles in the infusion tubing of the infusion unit.

[0020] In one possible implementation, the power supply unit includes a first power source, to which both the pressure detection element and the bubble detection element are electrically connected, the first power source being used to supply power to the pressure detection element and the bubble detection element.

[0021] The present invention also provides a power management method for an infusion pump, used in the aforementioned infusion pump system, the power management method for the infusion pump comprising:

[0022] Obtain the operating status of the infusion pump;

[0023] After determining that the working state of the infusion pump is the running state, it is determined whether the infusion pump is in the infusion interval state;

[0024] If the infusion pump is in an infusion gap state, the bubble detection device of the infusion pump is controlled to not work, and the pressure detection device of the infusion pump is controlled to collect pressure detection data at a first preset time interval.

[0025] The present invention also provides a power management method for an infusion pump. If the infusion pump determines that it is in an infusion gap state, the bubble detection device of the infusion pump is controlled to not work. Since the infusion pump does not deliver fluid to the patient during the infusion gap state, there is no need to detect whether there are bubbles in the infusion line. By controlling the bubble detection device of the infusion pump to not work during the infusion gap state, the energy consumption of the bubble detection device can be saved, thus saving electricity.

[0026] In one possible implementation, after determining that the infusion pump is in an operating state, and after determining whether the infusion pump is in an infusion gap state, the method further includes:

[0027] If it is determined that the infusion pump is not in the infusion gap state, then it is determined that the infusion pump is in the infusion state;

[0028] When the infusion pump is in the infusion state, the bubble detector is controlled to collect bubble detection data at a second preset time interval, and the pressure detector is controlled to collect pressure detection data at a third preset time interval, wherein the third preset time interval is less than or equal to the first preset time interval.

[0029] In one possible implementation, the power management method for the infusion pump further includes: determining whether the bubble detection data and / or the pressure detection data are abnormal, and if so, activating the alarm unit of the infusion pump.

[0030] In one possible implementation, after determining that the infusion pump is in an operating state, the step further includes:

[0031] The interaction unit controlling the infusion pump is not working;

[0032] The power supply unit of the infusion pump controls the infusion motor of the infusion pump to start the infusion motor, and controls the speed detection device of the infusion pump to collect the rotation speed data of the infusion motor, and controls the position detection device of the infusion pump to detect the rotation angle data of the output shaft of the infusion motor relative to a reference position.

[0033] If the rotation speed data or rotation angle data is abnormal, the alarm unit of the infusion pump is activated.

[0034] In one possible implementation, after determining that the infusion pump is in an operating state, the step further includes:

[0035] The power supply unit controlling the infusion pump supplies power to the drug cartridge detection device and the lock status detection device of the infusion pump, so that the drug cartridge detection device detects whether the drug cartridge is in a preset position, and the lock status detection device detects whether the drug cartridge is in a locked state.

[0036] If the drug box detection device detects that the drug box is not in the preset position, or the lock status detection device detects that the drug box is not in the locked state, then the alarm unit of the infusion pump is activated.

[0037] In one possible implementation, after obtaining the operating status of the infusion pump, the method further includes:

[0038] If the operating state of the infusion pump is determined to be interactive, then the power supply unit of the infusion pump is controlled to supply power to the interactive unit of the infusion pump so that the interactive unit can receive operation commands.

[0039] In one possible implementation, after obtaining the operating status of the infusion pump, the method further includes:

[0040] If the working state of the infusion pump is determined to be a dormant state or a powered-off state, then the interaction unit controlling the infusion pump, the pressure detection device, the bubble detection device, the speed detection device, and the position detection device will all be deactivated.

[0041] In one possible implementation, after the alarm unit that activates the infusion pump is activated, the system further includes:

[0042] The infusion pump motor is stopped rotating, and the interactive unit of the infusion pump is activated until the conditions for activating the alarm unit are eliminated or the interactive unit receives an operation command, at which point the alarm unit stops issuing warning information.

[0043] In one possible implementation, obtaining the operating status of the infusion pump specifically includes:

[0044] The operating state of the infusion pump is switched according to the operation command received by the interaction unit of the infusion pump.

[0045] The present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the above-described power management method for an infusion pump.

[0046] This invention determines that the infusion pump is in an infusion gap state by controlling the bubble detection device of the infusion pump to not work. This not only does not affect the normal infusion operation, but also saves energy consumption of the bubble detection device, saves electricity, and improves the battery life.

[0047] This invention facilitates the miniaturization of infusion pumps, reducing their size and weight, and improving portability.

[0092] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0093] Infusion pumps can be used to alleviate pain symptoms during surgery, postoperatively, postpartum, and after radiotherapy and chemotherapy, reduce clinical complications, promote patient recovery, and improve surgical success rates. They can also be used for continuous infusion of micro-volume medications. However, infusion pumps consume a significant amount of power, and to ensure sufficient battery life, large-capacity batteries are typically used. This inevitably increases the size and weight of the infusion pump, affecting its portability. To save energy and improve the battery life of infusion pumps, this application improves the infusion pump system and its power management method and device while meeting actual clinical needs.

[0094] Figure 1 This is an example line graph showing the relationship between the infusion motor angle (120°) and the infusion volume when the infusion pump is in operation. (Reference) Figure 1 As shown, the horizontal axis represents the rotation angle of the infusion motor 120 of the infusion pump, and the vertical axis represents the infusion volume. In this example, the infusion motor 120 rotates 360°. When the rotation angle of the infusion motor 120 is between 0° and 120°, the infusion volume is 0, indicating no actual medication output. When the rotation angle of the infusion motor 120 is between 120° and 240°, the infusion volume increases from 0 to 0.05 ml, indicating actual infusion; this state is defined as the infusion state. When the rotation angle of the infusion motor 120 is between 240° and 360°, the infusion volume remains at 0.05 ml without increasing, indicating no actual medication output. This state of no actual medication output is defined as the infusion interval state.

[0095] Of course, in other examples, the rotation angle of the infusion motor 120 during the 360° rotation of the infusion motor 120 while the infusion pump is in the infusion state can also be other angle ranges.

[0096] Therefore, the infusion pump system and its power management method and device provided in this application, based on the infusion principle, do not require all detection elements to collect data during the entire operation of the infusion motor 120. Thus, during the period when the infusion motor 120 is running but there is no actual infusion, i.e., when the infusion pump is in the infusion interval state, power can be withheld from the detection elements to achieve energy saving and extend the infusion pump's endurance.

[0097] The following description, with reference to the accompanying drawings, describes an infusion pump system and its power management method and apparatus provided in embodiments of the present invention.

[0098] refer to Figure 2 As shown, the present invention provides an infusion pump system, comprising:

[0099] Infusion pump body 100;

[0100] The memory 200 is used to record the working mode of each component under different operating instructions.

[0101] The detection unit 300 includes various detection elements;

[0102] The processor 400 and the detection unit 300 are connected to the processor 400. The processor 400 is configured to receive operation commands and control the working mode of each detection element and change the working state of the infusion pump.

[0103] The power supply unit 500 is connected to the processor 400. The power supply unit 500 is used to selectively supply power to each detection element of the detection unit 300 according to the electrical signal sent by the processor 400, so that the corresponding detection element can collect detection data.

[0104] The present invention provides an infusion pump system in which the power supply unit 500 selectively supplies power to each detection element of the detection unit 300 according to the electrical signal issued by the processor 400, so that the corresponding detection element can collect detection data. Therefore, during the infusion interval, it is possible to choose not to supply power to some detection elements to achieve the effect of saving power and extending the endurance of the infusion pump.

[0105] In one possible implementation, the infusion pump has an infusion pump system, see reference. Figure 3 , Figure 4 and Figure 5 As shown, the infusion pump body 100 includes a housing 110, referenced Figure 5 and Figure 6As shown, the housing 110 contains an infusion motor 120, a transmission assembly 130, an output assembly 140, a rebound device 150, and a stop-fluid pump assembly 160. The transmission assembly 130 includes a first gear 131, a second gear 132, a first rotating shaft 133, and a second transmission shaft 134. (Refer to...) Figure 6 and Figure 7 As shown, the first rotating shaft 133 and the second transmission shaft 134 are both rotatably disposed within the housing 110. The first rotating shaft 133 is connected to the output shaft end of the infusion motor 120. The first gear 131 is sleeved on the first rotating shaft 133, and the second gear 132 is connected to the second transmission shaft 134. The first gear 131 and the second gear 132 mesh with each other.

[0106] refer to Figure 7 and Figure 8 As shown, the output component 140 includes a first cam 141, a second cam 142, and a pump plate 143. Both the first cam 141 and the second cam 142 are connected to the second drive shaft 134. The first cam 141 abuts against the liquid-stopping pump plate assembly 160, and the second cam 142 abuts against the pump plate 143, so that when the cam portion of the second cam 142 abuts against the pump plate 143, the medicine in the medicine box is pumped out. When the arc portion of the second cam 142 abuts against the pump plate 143, no medicine is pumped out. The rebound device 150 is used to ensure that the pump plate 143, which abuts against the second cam 142, can be restored in time after deformation.

[0107] In one possible implementation, there may be two first cams 141, with the two first cams 141 distributed on both sides of the second cam 142 along the axial direction of the second drive shaft 134.

[0108] In one possible implementation method, refer to Figure 2 As shown, the memory 200 includes, but is not limited to, magnetic storage media, flash memory, etc. It can also retain data for a long time when power is off. The memory 200 records the working mode of each component under the working state corresponding to different operation instructions.

[0109] The memory 200 records the operating modes of each component under different operating commands. Specifically, the memory 200 records user-input commands corresponding to the operating states of the infusion pump. Each operating state of the infusion pump corresponds to the operating mode of each component. Operating states include, but are not limited to, power-off state, interactive state, running state, and sleep state. Running states include infusion interval state and infusion state. Each component includes a power supply unit 500 and various detection elements.

[0110] In one possible implementation, the processor 400 serves as the control center for the infusion pump and may be a microcontroller unit (MCU). The operation instructions received by the processor 400 may be user-inputted.

[0111] In one possible implementation, when the infusion pump is used for analgesia, the processor 400 can be a patient-controlled analgesia (PCA) controller.

[0112] In one possible implementation, the infusion pump system further includes: an infusion unit 600, an interaction unit 700, and an alarm unit 800. The infusion unit 600 is connected to the processor 400 and is used to drive the infusion motor 120 to rotate for infusion according to the electrical signal sent by the processor 400. The interaction unit 700 is connected to the processor 400 and is used to receive operation commands. The alarm unit 800 is connected to the processor 400 and is used to issue warning information according to the electrical signal sent by the processor 400.

[0113] In one possible implementation, the alarm unit 800 includes a warning light and / or a sounder, such as a buzzer or horn, and the warning information can be a flashing light emitted by the warning light and / or a warning sound emitted by the sounder, so as to achieve the effect of timely reminder to the user.

[0114] In one possible implementation method, refer to Figure 9 and Figure 10 As shown, the interaction unit 700 includes a display screen 710 and operation buttons. The display screen 710 may be a touch display screen 710, and the operation buttons include, but are not limited to, physical buttons or virtual buttons on the display screen 710. The interaction unit 700 enables information exchange between the user and the memory 200.

[0115] In one possible implementation method, refer to Figure 2 As shown, the various detection elements include at least a pressure detection element 310 and a bubble detection element 320. The pressure detection element 310 is used to detect whether the infusion tubing of the infusion unit 600 is unobstructed; the bubble detection element 320 is used to detect whether there are air bubbles in the infusion tubing of the infusion unit 600. The pressure detection element 310 and the bubble detection element 320 ensure the safe use of the infusion pump. The pressure detection element 310 can be a pressure sensor, and the bubble detection element 320 can be a bubble detection sensor.

[0116] In one possible implementation, the power supply unit 500 includes a first power source, and the pressure detection element 310 and the bubble detection element 320 are both electrically connected to the first power source. The first power source is used to provide the electrical energy required for the operation of the pressure detection element 310 and the bubble detection element 320. The power supply method of the first power source includes, but is not limited to, one or more of lithium battery power supply, dry cell battery power supply, DC regulated power supply, and wireless power supply.

[0117] To improve the accuracy of the test, there are at least two pressure testing elements 310, which are used to test the continuity of the upper and lower sections of the infusion line, respectively.

[0118] Setting both the pressure detection element 310 and the bubble detection element 320 to be connected to the same power source helps to reduce the complexity of the infusion pump system.

[0119] In one possible implementation, the multiple detection elements also include:

[0120] Speed ​​detection element 330 is used to detect the output shaft speed of infusion motor 120;

[0121] Position detection element 340 is used to detect the rotation angle of the output shaft of the infusion motor 120 relative to a reference position;

[0122] The drug box detection component 350 is used to detect whether the drug box is in a preset position; the preset position is the position where the drug box is fixed in the infusion pump, and the detection can be carried out at intervals, such as once every 3 seconds.

[0123] Lock status detection device 360 ​​is used to detect whether the medicine box is in a locked state.

[0124] In one possible implementation, the speed detection element 330 is disposed on a printed circuit board assembly (PCBA) in the side-view circuit for current or voltage. The speed detection element 330 can be a speed sensor, and the position detection element 340 can be an angle sensor or a position sensor.

[0125] In one possible implementation, the medication cartridge detector 350 and the lock status detector 360 are powered by the same power source. The medication cartridge detector 350 can be a position sensor, and the lock status detector 360 can be a lock status sensor.

[0126] In one possible implementation, the speed detection element 330 and the position detection element 340 are powered by the same power source.

[0127] In one possible implementation, the power supply unit 500 further includes a power manager that, based on control signals (i.e., on or off signals) issued by the processor 400, controls the circuit connection between the first power supply and the pressure detector 310 and / or the bubble detector 320, the circuit connection between the first power supply and the control drug cartridge detector 350 and the lock status detector 360, and the circuit connection between the first power supply and the speed detector 330 and the position detector 340. The power manager also provides charging protection for the first power supply.

[0128] refer to Figure 2 and Figure 11 As shown, the present invention also provides a power management method for an infusion pump, used in the above-mentioned infusion pump system. The power management method for the infusion pump includes:

[0129] S10. Obtain the operating status of the infusion pump;

[0130] S20. After determining that the working state of the infusion pump is the running state, determine whether the infusion pump is in the infusion gap state.

[0131] S30. If the infusion pump is in the infusion gap state, the bubble detection device controlling the infusion pump will not work, and the pressure detection device controlling the infusion pump will collect pressure detection data at a first preset time interval.

[0132] The present invention also provides a power management method for an infusion pump. If the infusion pump determines that it is in an infusion gap state, the bubble detection element 320 of the infusion pump is controlled to not work. Since the infusion pump does not deliver fluid to the patient during the infusion gap state, there is no need to detect whether there are bubbles in the infusion line. By controlling the bubble detection element 320 of the infusion pump to not work during the infusion gap state, the energy consumption of the bubble detection element 320 can be saved, thus saving electricity.

[0133] During infusion intervals, pressure detection data is collected at first preset time intervals to ensure the smooth flow of the infusion tubing, prevent accidental dislodgement of the infusion tubing, and ensure the operation of the infusion pump.

[0134] In one possible implementation method, refer to Figure 2 and Figure 12 As shown, after determining that the infusion pump is in the running state, and after judging whether the infusion pump is in the infusion gap state, the process also includes:

[0135] S40. If it is determined that the infusion pump is not in the infusion gap state, then it is judged that the infusion pump is in the infusion state.

[0136] S50. When the infusion pump is in the infusion state, the bubble detection device is controlled to collect bubble detection data at a second preset time interval, and the pressure detection device is controlled to collect pressure detection data at a third preset time interval, wherein the third preset time is less than or equal to the first preset time.

[0137] It is easy to understand that the third preset time is less than or equal to the first preset time because when the infusion pump is in the infusion state, it is necessary to ensure the unobstructed flow of the infusion tubing. If an accident such as the infusion tubing coming loose occurs, the medication will leak out, affecting the infusion operation. Therefore, pressure detection data is collected every third preset time interval when the infusion pump is in the infusion state. However, when the infusion pump is in the infusion interval state, in order to save power, pressure detection data can be collected at longer intervals. This can effectively detect the unobstructed flow of the infusion tubing and also achieve the effect of saving power.

[0138] In one possible implementation, the power management method for the infusion pump also includes:

[0139] S60. Determine if there are any abnormalities in the bubble detection data and / or pressure detection data; if so, proceed to step S61. Activate the alarm unit of the infusion pump to promptly notify the user to handle the abnormality.

[0140] In one possible implementation, the power management method for the infusion pump also includes:

[0141] Determine if there are any abnormalities in the bubble detection data and / or pressure detection data. If not, continue collecting bubble detection data and pressure detection data.

[0142] In one possible implementation method, refer to Figure 2 and Figure 13 As shown, after determining that the infusion pump is in the running state, the following steps are also included:

[0143] S11. The power supply unit of the infusion pump controls the infusion motor of the infusion pump to start the infusion motor, and controls the speed detection device of the infusion pump to collect the rotation speed data of the infusion motor, and controls the position detection device of the infusion pump to detect the rotation angle data of the output shaft of the infusion motor relative to the reference position.

[0144] S12. Determine if there are any abnormalities in the rotation speed data or rotation angle data. If so, activate the alarm unit of the infusion pump.

[0145] The infusion pump operates in the running state, meaning that during the operation of the infusion motor 120, the speed detection element 330 and the position detection element 340 start working to perform relevant detections. Specifically, the speed detection element 330 collects the rotational speed data of the infusion motor 120, which helps to promptly detect speed control issues and improve operational safety. The position detection element 340 detects the rotation angle data of the output shaft of the infusion motor 120 relative to a reference position, thereby determining whether the infusion pump is in an intermittent infusion state or in the infusion state.

[0146] The bubble detection element 320 of the infusion pump can be deactivated by cutting off the circuit connection between the power supply unit 500 and the bubble detection element 320; the interaction unit 700 of the infusion pump can also be deactivated by cutting off the circuit connection between the power supply unit 500 and the interaction unit 700, thereby turning off the display screen 710, achieving energy saving and extending the battery life of the infusion pump.

[0147] In one possible implementation method, refer to Figure 2 and Figure 14 As shown, after determining that the infusion pump is in the running state, the following steps are also included:

[0148] S13. The power supply unit of the infusion pump controls the infusion pump to supply power to the drug box detection device and the lock status detection device of the infusion pump, so that the drug box detection device detects whether the drug box is in a preset position, and the lock status detection device detects whether the drug box is in a locked state.

[0149] S14. If the drug box detection device detects that the drug box is not in the preset position, or the lock status detection device detects that the drug box is not in the locked state, the alarm unit of the infusion pump will be activated.

[0150] In one possible implementation, if the drug box detector detects that the drug box is in a preset position and the lock state detector detects that the drug box is in a locked state, then the operation continues.

[0151] The drug box detection unit 350 detects whether the drug box storing the medicine is in the preset position. If it is not in the preset position, the alarm unit 800 is activated to notify the user in time and suspend the infusion.

[0152] Considering that controlled medications such as analgesics also require infusion pumps, and that analgesics, being nationally controlled drugs, have certain side effects such as respiratory depression and addiction, a medication box lock will be installed. To enhance medication management and prevent unauthorized removal of the medication box, a lock status detection device 360 ​​will detect whether the medication box is locked, preventing unauthorized personnel from disassembling the box and improving medication management effectiveness. If the lock status detection device 360 ​​detects that the medication box is not locked, it will activate the infusion pump's alarm unit 800 to promptly notify the user.

[0153] In one possible implementation, after determining that the infusion pump is in operation, the method further includes: controlling the interaction unit 700 of the infusion pump to be inactive, thereby achieving energy saving. The inactivity of the interaction unit 700 can be achieved by disconnecting the circuit between the power supply unit 500 and the interaction unit 700, and by turning off the display screen 710 of the interaction unit 700.

[0154] In one possible implementation, after obtaining the operating status of the infusion pump, the process further includes:

[0155] If the infusion pump is determined to be in an interactive state, the power supply unit 500 of the infusion pump supplies power to the interactive unit 700, enabling the interactive unit 700 to receive operation commands. In the interactive state, the user can input some operating parameters of the infusion pump, such as setting the infusion rate to 1 ml / h, which means 20 infusions per hour with a 3-minute interval between each infusion. Therefore, in the interactive state, the power supply unit 500 needs to supply power to the interactive unit 700 so that the interactive unit 700 can receive operation commands and transmit the received operation commands to the processor 400.

[0156] In one possible implementation, after obtaining the operating status of the infusion pump, the process further includes:

[0157] If the working state of the infusion pump is determined to be a dormant state or a shutdown state, then the interaction unit 700 controlling the infusion pump, the pressure detection element 310, the bubble detection element 320, the speed detection element 330, and the position detection element 340 will all be inactive.

[0158] The working states of an infusion pump are: off state, interactive state, running state, and sleep state. The running state includes infusion interval state and infusion state.

[0159] To reduce power consumption when the infusion pump is in sleep or off state, the interaction unit 700, pressure detection device 310, air bubble detection device 320, speed detection device 330, and position detection device 340 of the infusion pump are all inactive, and the display screen 710 of the interaction unit 700 is off, saving power consumption. This achieves the effect of saving energy. Until the interaction unit 700 receives a receiving operation command, the working state of the infusion pump switches to the interaction state, the display screen 710 is lit up, and relevant settings can be made to achieve faster startup.

[0160] In one possible implementation, after activating the alarm unit of the infusion pump, the following is also included:

[0161] S15. Control the infusion pump motor to stop rotating and start the infusion pump's interactive unit until the conditions for starting the alarm unit are eliminated or the interactive unit receives an operation command, at which point the alarm unit stops issuing warning information.

[0162] After the alarm unit 800 of the infusion pump is activated, the alarm unit 800 issues a warning message to notify the user that an abnormal situation has occurred and the infusion needs to be stopped to avoid a safety accident. The type of abnormal situation can be notified to the user through the interaction unit 700.

[0163] There are two types of abnormal situations. One type is an abnormal situation that can be resolved on its own, such as when the infusion tubing is blocked, the pressure detection device 310 detects abnormal pressure data, and then the infusion tubing clears itself, and the pressure detection device 310 no longer detects abnormal pressure data, indicating that the abnormal situation has been resolved on its own, and the alarm unit 800 can stop issuing warning messages. The other type is an abnormal situation that cannot be resolved on its own, such as when the pressure detection device 310 detects an abnormality, such as when the infusion tubing becomes detached. This type of abnormality cannot recover on its own and requires user intervention. Therefore, the alarm unit 800 will stop issuing warning messages once the user has resolved the abnormality and inputs an operation command through the interaction unit 700.

[0164] This invention ensures the safety of intravenous infusion without affecting normal infusion procedures, while also achieving energy savings and extending battery life, making it highly practical. Furthermore, it boasts advantages such as small size and high portability.

[0165] In one possible implementation, obtaining the operating status of the infusion pump specifically includes:

[0166] The operating state of the infusion pump is switched according to the operation command received by the interaction unit 700 of the infusion pump.

[0167] In one possible implementation, the operating state of the infusion pump is switched according to the operation command received by the interaction unit 700. Specifically, this includes: the user can switch the operating state of the infusion pump from interactive state, running state, or sleep state to the off state using the on / off button on the operation button of the interaction unit 700; the user can also switch the operating state of the infusion pump from the off state to the interactive state using the operation button of the interaction unit 700. Alternatively, the user can switch the operating state of the infusion pump from the running state or sleep state to the interactive state by inputting the corresponding operation command as needed, thus putting the infusion pump into the desired operating state.
