[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0044] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties.

[0045] For the condition monitoring of medical devices such as infusion pumps and injection pumps, it is possible to determine whether the medical devices are malfunctioning. This application aims to provide a method for condition monitoring of medical devices.

[0046] Example 1

[0047] like Figure 1 As shown, some embodiments of this application provide a detection method applied to a medical device. The medical device includes a driver, a driver control component, and a controller, wherein the controller controls the driver control component to drive the driver to operate. The method specifically includes the following steps:

[0048] S101. Obtain the operating status parameters of the driving component.

[0049] Among them, the operating state parameters of the driving component are used to characterize the operating state of the driving component.

[0050] In some embodiments, the operating status parameters include at least one of the following: voltage value, current value, torque, and rotational speed.

[0051] S102. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0052] The preset judgment rule is a pre-determined judgment rule used to determine the status information of the medical device. By inputting the operating status parameters of the driver into the preset judgment rule, the judgment result output by the preset judgment rule is determined, thus determining the status information of the medical device.

[0053] In some embodiments, the preset judgment rule includes at least one judgment range. If the operating state parameters of the driver are within a certain preset judgment range, the medical device is determined to be in the corresponding state.

[0054] In some embodiments, the preset judgment rule includes a judgment formula and at least one judgment range. The operating state parameters of the driving component are substituted into the judgment formula to calculate an intermediate result. When the intermediate result falls within a preset judgment range, the medical device is determined to be in the corresponding state.

[0055] In some embodiments, the preset judgment rule includes a preset application scenario and at least one judgment range. Since the judgment ranges for the operating status parameters of the driver may overlap or intersect in different application scenarios, the medical device may be unable to distinguish the corresponding status information. Therefore, the user can pre-determine the application scenario in the medical device. Based on this application scenario, when the operating status parameters of the driver fall within a certain judgment range, the corresponding working state of the medical device in this application scenario is determined. By adding the condition of the preset application scenario, the accuracy of the medical device in judging the status information of the driver is improved.

[0056] In the above technical solution, the operating status parameters of the driving component are obtained to detect the operating status of the driving component. Then, based on the operating status parameters of the driving component and the preset judgment rules, the status information of the medical device is determined. In this way, the status information of the medical device can be determined, the status monitoring of the medical device can be realized, and the reliability of the medical device during use can be guaranteed.

[0057] Example 2

[0058] Some embodiments of this application provide a detection method applied to a medical device, the method specifically including the following steps:

[0059] S201. Obtain the operating status parameters of the driving component.

[0060] Among them, the operating status parameters are related to the load driven by the driver. That is, when the operating status parameters of the driver characterize the operating status of the driver, they are used to characterize the operating status related to the load when the driver drives the load.

[0061] S202. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0062] Since the operating status parameters of the driving component are related to the load driven by the driving component, the judgment result output by the preset judgment rule is also related to the judgment result when the driving component is driving the load, thus determining the status information of the medical device when driving the load.

[0063] In the above technical solution, by acquiring the load-related operating status parameters in the driving component, the operating status of the driving component when driving the load is detected. Then, based on the operating status parameters of the driving component and the preset judgment rules, the status information of the medical device when driving the load is determined, thereby realizing the status monitoring of the medical device when driving the load. This can ensure the reliability of the medical device during use.

[0064] Example 3

[0065] Some embodiments of this application provide a detection method applied to a medical device, the method specifically including the following steps:

[0066] S301. Obtain the operating status parameters of the driving component.

[0067] The operating status parameters include the operating current of the drive unit. A current sensor can be used to detect the operating current of the drive unit and output a voltage value. This voltage value can then be converted to output the operating current of the drive unit. Alternatively, a current sensor can be used to detect the operating current of the drive unit and output the operating current of the drive unit.

[0068] S302. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0069] The preset judgment rules include a preset current range. When the operating current of the drive component is within the preset current range, the drive component is in a normal operating state. When the operating current of the drive component is outside the preset current range, the drive component is in an abnormal operating state.

[0070] The operating current of the drive unit can characterize the load condition connected to the drive unit. When the connected load is normal, the operating current of the drive unit is within the preset current range. When the connected load is abnormal, the operating current of the drive unit is outside the preset current range.

[0071] More specifically, when the operating current of the drive unit exceeds the upper limit of the preset current range, it indicates that the drive unit outputs a relatively large driving force, which may indicate that there is additional resistance hindering the drive unit. When the operating current of the drive unit is less than the lower limit of the preset current range, it indicates that the drive unit outputs a relatively small driving force, which may indicate that the load is not properly connected to the load terminal of the drive unit.

[0072] The preset current range is also related to the load type and the rotational speed of the drive component. Different load types correspond to different preset current ranges.

[0073] When the load type remains unchanged, the higher the rotation speed, the greater the operating current when driving the load normally, and the greater the lower and upper limits of the preset current range.

[0074] For example, when the speed of the drive component is 60 rpm, the corresponding operating current is 100mA to 110mA. When the speed of the drive component is 70 rpm, the corresponding operating current is 120mA to 130mA.

[0075] In the above technical solution, by detecting the operating current of the driving component and determining the status information of the medical device when driving a load based on the operating current of the driving component and a preset current range, the operating status of the medical device when carrying a load can be judged, thus ensuring the reliability of the medical device during use. Furthermore, the detection of the operating status of the medical device when carrying a load can be achieved without additional mechanical sensors, greatly simplifying the complexity of the mechanical structure design.

[0076] Example 4

[0077] Some embodiments of this application provide a detection method applied to a medical device, the method specifically including the following steps:

[0078] S401. Obtain the operating status parameters of the drive unit.

[0079] Among them, the operating status parameters include torque values.

[0080] Medical devices also include force sensors, which are placed at the load end connected to the drive component. The force sensors are used to detect the torque at the load end connected to the drive component.

[0081] More specifically, the operating status parameters of the drive components are obtained, including:

[0082] The torque measurement voltage is obtained from the force sensor, and the torque value of the drive component is obtained based on the torque measurement voltage and the preset torque conversion coefficient. Thus, the torque value of the drive component is obtained through the force sensor.

[0083] The preset torque conversion coefficient is determined based on the internal structure of the force sensor and can be determined by querying the working parameters of the force sensor.

[0084] In some embodiments, obtaining the torque value of the drive component based on the torque measurement voltage and a preset torque conversion coefficient includes:

[0085] The product of the torque measurement voltage and the preset torque conversion coefficient is determined as the torque value of the driving component.

[0086] In some embodiments, a current sensor can be used to detect the operating current of the drive device and output a voltage value. This voltage value is then converted to output the operating current of the drive device. The torque value of the drive device is then calculated based on the operating current and a preset current-torque conversion coefficient. For example, the current-torque conversion coefficient can be 0.9.

[0087] S402. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0088] The preset judgment rules include a preset torque range. When the torque value of the driving component is within the preset torque range, the driving component is in a normal operating state. When the torque value of the driving component is outside the preset torque range, the driving component is in an abnormal operating state.

[0089] More specifically, if the torque value of the drive component exceeds the upper limit of the preset torque range, there may be additional resistance hindering the drive component. If the torque value of the drive component is less than the lower limit of the preset torque range, the load may not be properly connected to the load end of the drive component.

[0090] The preset torque range is also related to the load type. Different load types correspond to different preset torque ranges. By setting the appropriate preset torque range according to the load type, it can adapt to the detection of working conditions when equipped with different types of loads, thus improving the accuracy of the detection results.

[0091] In the above technical solution, by detecting the torque value of the driving component and determining the status information of the medical device when driving the load based on the torque value of the driving component and the preset torque range, the working status of the medical device when carrying the load can be judged, thus ensuring the reliability of the medical device during use.

[0092] Example 5

[0093] Some embodiments of this application provide a detection method applied to a medical device, the method specifically including the following steps:

[0094] S501. Obtain the operating status parameters of the drive component.

[0095] Among them, the operating status parameters include voltage values. A current sensor can be used to detect the operating current of the drive unit and convert the current value into a voltage value.

[0096] S502. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0097] The preset judgment rules include a preset voltage range. When the voltage value of the driving component is within the preset voltage range, the driving component is in a normal operating state. When the voltage value of the driving component is outside the preset voltage range, the driving component is in an abnormal operating state.

[0098] The operating voltage of the drive unit can characterize the load condition connected to the drive unit. When the connected load is normal, the operating voltage of the drive unit is within the preset voltage range. When the connected load is abnormal, the operating voltage of the drive unit is outside the preset voltage range.

[0099] More specifically, when the operating voltage of the drive unit is greater than the upper limit of the preset voltage range, it indicates that the drive unit outputs a relatively large driving force, which may indicate that there is additional resistance hindering the drive unit. When the operating voltage of the drive unit is less than the lower limit of the preset voltage range, it indicates that the drive unit outputs a relatively small driving force, which may indicate that the load is not properly connected to the load terminal of the drive unit.

[0100] In the above technical solution, by detecting the voltage value of the driving component and determining the state information of the medical device when driving a load based on the voltage value of the driving component and a preset voltage range, the working state of the medical device when carrying a load can be determined, thus ensuring the reliability of the medical device during use. Dynamic load detection can be achieved without additional mechanical sensors, greatly simplifying the complexity of mechanical structure design.

[0101] Figure 2 The diagram below illustrates the circuit schematic of a drive control unit 200 provided in some embodiments of this application. The drive control unit 200 includes a drive circuit 202 and a control circuit 201. The output terminal of the drive circuit 202 is electrically connected to the drive unit 300, and the input terminal of the drive circuit 202 is connected to the output terminal of the control circuit 201. The control circuit 201 outputs a control signal, which controls the drive circuit 202 to output a drive current, which drives the drive unit 300 to operate.

[0102] The controller 100 is connected to the control circuit 201. The controller 100 outputs control commands, and the control circuit 201 is used to convert the control commands into control signals for output.

[0103] In some embodiments, continue to refer to Figure 2 When the driving component 300 is a motor, the driving circuit 202 is a three-phase bridge arm circuit, and the control circuit 201 is used to output PWM signals.

[0104] In some embodiments, continue to refer to Figure 2 The medical device also includes a data acquisition circuit 700, which is used to acquire the operating current of the driving component 300, so that the medical device can determine the operating status of the medical device based on the operating current of the driving component and preset judgment rules.

[0105] In some embodiments, continue to refer to Figure 2 When the drive circuit 202 is a three-phase bridge arm circuit, the acquisition circuit 700 includes three bridge arm amplifiers 701 and three bridge arm reference resistors Rref. The input terminal of each bridge arm amplifier 701 is connected to the corresponding bridge arm to amplify the bridge arm current and output it. The first terminal of each bridge arm reference resistor Rref is connected to the output terminal of the corresponding bridge arm amplifier 701, and the second terminal of the bridge arm reference resistor Rref is connected to the reference voltage Vref. By reading the output voltage of the bridge arm amplifier 701, the voltage value is obtained, and the voltage value is used to characterize the working state of the motor.

[0106] In some embodiments, the acquisition circuit 700 further includes a conversion module (not shown), which is used to receive the voltage on the bridge arm reference resistor Rref and convert the voltage on the bridge arm reference resistor Rref into the operating current of the motor.

[0107] The operating current of the motor can be calculated using the following formula:

[0108]

[0109] I represents the motor current value, V out This represents the output voltage of the bridge arm amplifier 701, V. ref Represents the reference voltage, G represents the amplification gain of the bridge arm amplifier 701, and R... ref This indicates the bridge arm reference resistance.

[0110] Among them, V out It can be the output voltage Vout1 of the first bridge arm amplifier, the output voltage Vout2 of the second bridge arm amplifier, the output voltage Vout3 of the third bridge arm amplifier, the average of the output voltages of any two of the three bridge arm amplifiers, or the average of the output voltages of the three bridge arm amplifiers.

[0111] In some embodiments, the acquisition circuit 700 further includes a filtering circuit (not shown in the figure). The filtering circuit is connected to the input terminal of the bridge arm amplifier 701. The bridge arm current is filtered by the filtering circuit and then output to the bridge arm amplifier 701. In this way, noise signals in the bridge arm current are filtered out, the bridge arm current can be accurately acquired, and the bridge arm current is amplified and output. The amplified current is then sampled to obtain the sampled voltage value as the operating status parameter of the driving device, thereby improving accuracy.

[0112] In some embodiments, the acquisition circuit 700 further includes a filtering circuit (not shown in the figure). The filtering circuit is connected to the input terminal of the bridge arm amplifier 701. The filtering circuit is used to filter the current output by the bridge arm amplifier 701, thereby filtering out the noise of the output current of the bridge arm amplifier 701. The filtered current is then sampled to obtain the sampled voltage value as the operating status parameter of the driving device, thereby improving accuracy.

[0113] Example 6

[0114] like Figure 3 As shown, some embodiments of this application provide a detection method applied to medical devices, which specifically includes the following steps:

[0115] S601. Obtain the operating status parameters of the driving component.

[0116] Among them, the operating status parameters of the driving component are used to characterize the operating status of the driving component, and the operating status parameters are related to the load driven by the driving component.

[0117] S602. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0118] In some embodiments, the preset judgment rule includes at least one judgment range. If the operating state parameters of the driver are within a certain preset judgment range, the medical device is determined to be in the corresponding state.

[0119] In some embodiments, the preset judgment rule includes a judgment formula and at least one judgment range. The operating state parameters of the driving component are substituted into the judgment formula to calculate an intermediate result. When the intermediate result falls within a preset judgment range, the medical device is determined to be in the corresponding state.

[0120] In some embodiments, different types of loads require different driving forces, so multiple judgment ranges can be predetermined, each corresponding to a type of load. Thus, the type of load mounted on the medical device is determined based on the operating state parameters of the driving component.

[0121] In some embodiments, different states of the load require different driving forces, so multiple judgment ranges can be predetermined, each corresponding to a state of the load. Thus, the state of the load mounted on the medical device is determined based on the operating state parameters of the driving component.

[0122] S603, Output status information.

[0123] Specifically, after determining the status information of the medical device, the status information is output.

[0124] In some embodiments, the medical device is provided with a display screen that displays status information.

[0125] In some embodiments, the medical device is equipped with a speaker to output status information via voice broadcast.

[0126] In some embodiments, the output status information may include load status information, such as abnormal load status or normal load status.

[0127] In some embodiments, the output status information may include the type of load being carried.

[0128] In some embodiments, when the type of load being loaded is detected, if the type of load is not the required type, a load type error message can be output. If the type of load is the required type, a load type normal message can be output.

[0129] In the above technical solution, by acquiring the load-related operating status parameters in the driving component, the operating status of the driving component when driving the load is detected. Then, based on the operating status parameters of the driving component and the preset judgment rules, the status information of the medical device when driving the load is determined, thereby realizing the status monitoring of the medical device when driving the load and outputting the corresponding status information, thus realizing the detection of multiple states.

[0130] In some embodiments, the medical device is a nutrient solution infusion device. Figure 4 This is a schematic diagram of a nutrient solution infusion device. Figure 5 This is a schematic diagram showing consumable 601 mounted on consumable support plate 603. Figure 6 This is a schematic diagram showing consumable 601 fixed to the nutrient solution infusion device via consumable support plate 603. The nutrient solution infusion device also includes a reducer (not shown) and a roller structure 500. The drive component is connected to the reducer, and the reducer is connected to the roller structure 500.

[0131] The roller structure 500 is configured to rotate under the drive of the drive component 300, thereby driving the fluid flow in the consumable 601. The roller structure 500 is detachably connected to the reducer via a quick-release connector.

[0132] Consumable 601 is mounted on roller structure 500, so that roller structure 500 can drive the fluid flow in consumable 601 when it rotates. The rotational speed of roller structure 500 is related to the fluid flow rate, for example: the fluid flow rate is the product of the rotational speed of roller structure 500 and the rotational speed-flow rate conversion coefficient.

[0133] Consumable 601 can be a silicone tube. After the silicone tube is installed on the roller structure 500, it is fixed to the body of the nutrient solution infusion device by the consumable support plate 603.

[0134] Example 7

[0135] Some embodiments of this application provide a detection method applied to a nutrient solution infusion device, the method specifically including the following steps:

[0136] S701, Obtain the operating status parameters of the drive component.

[0137] The operating status parameters of the drive unit include its operating current. The operating current of the drive unit is obtained when the medical device is running under load.

[0138] For example: the operating current of the drive components of a nutrient solution infusion device when it is running with a roller structure installed and consumables installed in the roller structure.

[0139] S702. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0140] The preset judgment rules include the current range of consumables in place and / or the current range of consumables falling off.

[0141] When the consumables are located within the roller structure, the nutrient solution infusion device is tested multiple times at a certain test flow rate to obtain multiple consumable in-situ currents. The range of consumable in-situ currents is then obtained through statistical analysis of these multiple consumable in-situ currents.

[0142] By conducting multiple tests on the nutrient solution infusion equipment when the consumables were not located in the roller structure, multiple consumable detachment currents were obtained, and statistical analysis was performed on the multiple consumable detachment currents to obtain the range of consumable detachment currents.

[0143] For example: Install standard consumables on the roller structure, and test the nutrient solution infusion device at a flow rate of 700 mL / h to obtain the test current of multiple motors. Calculate the average value of the test current of multiple motors as 125 mA, and set the current range of the consumables in place as (125 mA, 125 mA + 12.5 mA).

[0144] For example: Install standard consumables on the roller structure, test the nutrient solution infusion device at a flow rate of 1200mL / h, obtain the test current of multiple motors, calculate the average value of the test current of multiple motors as 200mA, and set the current range of consumables in place as (200mA, 220mA).

[0145] In some embodiments, during the usage period of the consumable, the operating current of the drive unit is compared with the consumable in-situ current range of the drive unit. When the operating current of the drive unit is not within the consumable in-situ current range, a consumable detachment alarm is output. When the operating current of the drive unit is within the consumable in-situ current range, consumable in-situ information is output.

[0146] In some embodiments, when the operating current of the drive is less than the lower limit of the current range of the consumable in place, an alarm message for the consumable being dislodged is output.

[0147] In some embodiments, during the usage period of the consumable, the operating current of the drive unit is compared with the consumable detachment current range of the drive unit. When the operating current of the drive unit is within the consumable detachment current range, a consumable detachment alarm message is output. When the operating current of the drive unit is not within the consumable detachment current range, consumable presence information is output.

[0148] In some embodiments, during the usage period of the consumable, the operating current of the drive unit is compared with the consumable in-situ current range. When the operating current of the drive unit is within the consumable in-situ current range, consumable in-situ information is output. When the operating current of the drive unit is not within the consumable in-situ current range, the operating current of the drive unit is compared with the consumable detachment current range of the drive unit. When the operating current of the drive unit is within the consumable detachment current range, consumable detachment alarm information is output.

[0149] In the above technical solution, considering that the current of the drive component when the nutrient solution infusion pump is running under load is very different from that when it is running under no load, by obtaining the working current of the drive component and comparing the working current of the drive component with the current range of the consumable in place, it is determined whether the consumable is located within the roller structure. In this way, the status detection of whether the consumable in the nutrient solution infusion equipment is located within the roller structure can be realized without adding an additional mechanical structure, thus simplifying the structure of the nutrient solution infusion pump.

[0150] Example 8

[0151] Some embodiments of this application provide a detection method applied to a medical device, the method specifically including the following steps:

[0152] S801, Obtain the operating status parameters of the driving component.

[0153] The operating status parameters of the drive unit include its operating current. The operating current of the drive unit is obtained when the medical device is running under load.

[0154] For example: the operating current of the drive components of a nutrient solution infusion device when it is running with a roller structure installed and consumables installed in the roller structure.

[0155] S802. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0156] Among them, the preset judgment rules include the consumable in-situ current range. By conducting multiple tests on the nutrient solution infusion equipment when the consumable is located in the roller structure, multiple consumable in-situ currents are obtained, and the consumable in-situ current range is obtained by statistical analysis of multiple consumable in-situ currents.

[0157] The medical device also includes an in-situ detection element, which is positioned opposite the roller structure and is used to detect whether the roller structure is mounted on the drive unit.

[0158] In some embodiments, the status information of the medical device is determined based on the operating status parameters of the driver and preset judgment rules, specifically including the following steps:

[0159] Step a1: Compare the operating current of the drive unit with the in-situ current range of the drive unit's consumables.

[0160] Step b1: When the operating current of the drive unit is not within the range of the consumable in-situ current, continue to acquire the detection results of the in-situ detection unit.

[0161] Step c1: When the in-place detection component detects that the roller structure is in place, it outputs an alarm message for the detachment of consumables.

[0162] Step d1: When the in-place detection component detects that the roller structure is not in place, it outputs roller structure in-place abnormality information.

[0163] Step e1: When the operating current of the drive unit is within the consumable in-situ current range, output consumable in-situ information.

[0164] In some embodiments, the status information of the medical device is determined based on the operating status parameters of the driver and preset judgment rules, specifically including the following steps:

[0165] Step a2: Compare the operating current of the drive unit with the consumable shedding current range of the drive unit.

[0166] Step b2: When the operating current of the drive unit is within the range of the consumable detachment current, continue to obtain the detection results of the detachment detection unit.

[0167] Step c2: When the detachment detection component detects that the roller structure is in place, it outputs a consumable detachment alarm message.

[0168] Step d2: When the detachment detection component detects that the roller structure is not in place, it outputs roller structure detachment abnormality information.

[0169] Step e2: When the operating current of the drive unit is not within the range of the consumable detachment current, output consumable presence information.

[0170] In some embodiments, the in-situ detection element includes a Hall sensor 401 and a plurality of magnets 402. The Hall sensor 401 is located inside the nutrient solution infusion device and is disposed close to the roller structure. A plurality of magnets 402 are disposed on the roller structure and arranged circumferentially along the roller structure.

[0171] When the drive mechanism of the nutrient solution infusion device rotates the roller structure, each magnet 402 sequentially approaches the Hall sensor 401 and then moves away from it. When the Hall sensor 401 approaches the magnet 402, its output signal strength increases; when it moves away, its output signal strength decreases, thus causing the Hall sensor 401 to output a pulse signal. The number of pulse signals output by the Hall sensor 401 during one rotation of the roller structure is related to the number of magnets 402.

[0172] When no roller structure is installed on the drive unit, the output signal of the Hall sensor 401 will not change as the magnet 402 approaches or moves away from the magnet 402 because there is no magnet 402.

[0173] By acquiring the output signal of Hall sensor 401, it can be determined whether Hall sensor 401 outputs a pulse signal. If a pulse signal is output, it indicates that the roller structure is mounted on the driving component. If a high or low level is output, it indicates that the roller structure is not mounted on the driving component.

[0174] The process of determining the status information of the medical device based on the operating status parameters of the driving components and preset judgment rules includes the following steps:

[0175] Step a2: Compare the operating current of the drive unit with the in-situ current range of the drive unit's consumables.

[0176] Step b2: When the operating current of the drive unit is not within the range of the consumable in-situ current, continue to acquire the detection result of the Hall sensor 401.

[0177] Step c2: When Hall sensor 401 outputs a pulse signal, it outputs an alarm message for the detachment of consumables.

[0178] Step d2: When Hall sensor 401 outputs a high or low level, it outputs an abnormal information about the roller structure being in place.

[0179] Step e2: When the operating current of the drive unit is within the consumable in-situ current range, output consumable in-situ information.

[0180] By setting a Hall sensor 401 on the nutrient solution infusion device and a magnet 402 on the roller structure, the roller structure will rotate under the drive of the drive component when it is mounted on the drive component, causing the Hall sensor 401 to output a pulse signal, thus realizing the in-situ detection of the roller structure.

[0181] In the above technical solution, considering that the roller structure not being installed on the drive component and the consumables detaching from the roller structure will both cause the drive component to rotate under no-load, resulting in the drive component's operating current being outside the consumables' in-situ current range, to improve the accuracy of the detection results, the drive component's operating current is compared with the consumables' in-situ current range. When the drive component's operating current is outside the consumables' in-situ current range, it is further determined whether the roller structure is installed on the drive component. When the roller structure is installed on the drive component, it is determined that the consumables in the medical device are not located within the roller structure. Since no additional mechanical structure is needed, the structure of the nutrient solution infusion pump is simplified.

[0182] Example 9

[0183] Some embodiments of this application provide a detection method applied to a nutrient solution infusion device, the method specifically including the following steps:

[0184] S901, Obtain the operating status parameters of the driving component.

[0185] The operating status parameters of the drive components include their torque values. The torque values ​​of the drive components are obtained when the medical device is running under load.

[0186] For example: obtaining the torque value of the driving component when the nutrient solution infusion equipment is running with a roller structure installed and consumables installed in the roller structure.

[0187] S902. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0188] Among them, the preset judgment rules include the range of consumable torque values. When the consumable is located in the roller structure, multiple tests are conducted on the nutrient solution infusion device at a certain test flow rate to obtain multiple consumable torque values. The range of consumable torque values ​​is obtained by statistical analysis of the multiple consumable torque values.

[0189] For example: Install standard consumables on the roller structure, and test the nutrient solution infusion device at a flow rate of 700 mL / h to obtain the test torque values ​​of multiple motors. Calculate the average value of the test torque values ​​of multiple motors as 112.5 mN.m, and set the range of in-situ torque values ​​of consumables as (112.5 mN.m, 112.5 × 1.1 mN.m).

[0190] For example: Install standard consumables on the roller structure, and test the nutrient solution infusion device at a flow rate of 1200mL / h to obtain the test torque values ​​of multiple motors. Calculate the average value of the test torque values ​​of multiple motors as 180mN.m, and set the range of in-situ torque values ​​of consumables as (180mN.m, 180mN.m + 18mN.m).

[0191] During the usage period of the consumable, the torque value of the drive component is compared with the consumable in-place torque value range of the drive component. When the torque value of the drive component is not within the consumable in-place torque value range, a consumable detachment alarm message is output. When the torque value of the drive component is within the consumable in-place torque value range, consumable in-place information is output.

[0192] In some embodiments, when the torque value of the driving component is less than the lower limit of the consumable positioning torque value range, an alarm message for consumable falling off is output.

[0193] In the above technical solution, considering that the torque value of the drive component when the nutrient solution infusion pump is running under load and the torque value of the drive component when running under no load will be very different, by obtaining the torque value of the drive component, comparing the torque value of the drive component with the torque value range of the consumable in place, it is determined whether the consumable is located within the roller structure. In this way, the status detection of whether the consumable in the nutrient solution infusion equipment is located within the roller structure is realized.

[0194] Example 10

[0195] Some embodiments of this application provide a detection method applied to a medical device, the method specifically including the following steps:

[0196] S1001. Obtain the operating status parameters of the driving component.

[0197] The operating status parameters of the drive unit include its operating current. The operating current of the drive unit is obtained when the medical device is running under load.

[0198] For example: the operating current of the drive components of a nutrient solution infusion device when it is running with a roller structure installed and consumables installed in the roller structure.

[0199] S1002. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0200] The preset judgment rules include a consumable replacement current threshold. This threshold is used to indicate when to replace consumables. If consumables are used for too long, their tension will decrease, which will reduce the accuracy of the infusion.

[0201] In some embodiments, unused consumables are installed in a roller structure. Multiple consumable replacement currents are obtained by performing multiple tests on the nutrient solution infusion device at a certain test flow rate. The consumable replacement current threshold is obtained by statistical analysis of the multiple consumable replacement currents.

[0202] For example: Install standard consumables on the roller structure, and test the nutrient solution infusion device at a flow rate of 700mL / h to obtain the test current of multiple motors. Calculate the average value of the test current of multiple motors as 125mA, and set the consumable replacement current threshold as 125mA + 125 × 0.02mA.

[0203] In some embodiments, consumables are installed in a roller structure. By testing the consumables throughout their entire lifecycle, the operating current of the drive component in the nutrient solution infusion device at different stages, as well as the infusion accuracy of the nutrient solution infusion device at different stages, are obtained. The operating current of the drive component corresponding to when the infusion accuracy of the nutrient solution infusion device falls below a preset threshold is used as the consumable replacement current threshold.

[0204] Based on the operating status parameters of the driving components and preset judgment rules, the status information of the medical device is determined, specifically including:

[0205] The operating current of the drive unit is compared with the consumable replacement current threshold. When the operating current of the drive unit is less than the consumable replacement current threshold, a consumable replacement reminder message is output.

[0206] In the above technical solution, considering that the working current of the drive component will also decrease when the tension of the consumable decreases, the working current of the drive component is detected and compared with the consumable replacement current threshold. If it is less than the consumable replacement current threshold, it is determined that the tension of the consumable has decreased, thereby reminding the user to replace the infusion consumable.

[0207] Example 11

[0208] Some embodiments of this application provide a detection method applied to a medical device, the method specifically including the following steps:

[0209] S1101. Obtain the operating status parameters of the driving component.

[0210] The operating status parameters of the drive components include their torque values. The torque values ​​of the drive components are obtained when the medical device is running under load.

[0213] The preset judgment rules include a consumable replacement torque threshold. This threshold indicates when consumables should be replaced. If consumables are used for too long, their tension will decrease, which will reduce the accuracy of the infusion.

[0214] In some embodiments, unused consumables are installed in a roller structure. Multiple consumable replacement torque values ​​are obtained by performing multiple tests on the nutrient solution infusion device at a certain test flow rate. Statistical analysis is then performed on the multiple consumable replacement torque values ​​to obtain a consumable replacement torque value threshold.

[0215] For example: Install standard consumables on the roller structure, and test the nutrient solution infusion device at a flow rate of 700 mL / h to obtain the test torque values ​​of multiple motors. Calculate the average value of the test torque values ​​of multiple motors as 112.5 mN.m, and set the consumable replacement torque threshold as 112.5 mN.m + 112.5 × 0.02 mN.m.

[0216] In some embodiments, consumables are installed in a roller structure. By testing the consumables throughout their entire lifecycle, the torque values ​​of the drive components in the nutrient solution infusion device at different stages, as well as the infusion accuracy of the nutrient solution infusion device at different stages, are obtained. The torque value of the drive components corresponding to when the infusion accuracy of the nutrient solution infusion device falls below a preset threshold is used as the consumable replacement torque threshold.

[0217] Based on the operating status parameters of the driving components and preset judgment rules, the status information of the medical device is determined, specifically including:

[0218] The torque value of the drive component is compared with the consumable replacement torque value threshold. When the torque value of the drive component is less than the consumable replacement torque value threshold, a consumable replacement reminder message is output.

[0219] In the above technical solution, considering that the torque value of the driving component will also decrease when the tension of the consumable decreases, the torque value of the working component is detected and compared with the torque value threshold of the consumable replacement torque value. If it is less than the torque value threshold of the consumable replacement torque value, it is determined that the tension of the consumable has decreased, thereby reminding the user to replace the infusion consumable.

[0221] Some embodiments of this application provide a detection method applied to a medical device, the method specifically including the following steps:

[0222] S1201. Obtain the operating status parameters of the driving component.

[0223] The operating status parameters of the drive unit include its operating current. The operating current of the drive unit is obtained when the medical device is running under load.

[0224] For example: the operating current of the drive components of a nutrient solution infusion device when it is running with a roller structure installed and consumables installed in the roller structure.

[0225] S1202. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0226] The preset judgment rules include the standard current range for multiple consumable types. The tension of consumables of different types will vary, and the operating current of the corresponding driving components will also be different.

[0227] For each type of consumable, the standard current range for various types of consumables was obtained by conducting multiple tests on the nutrient solution infusion device when the consumable was located within the roller structure.

[0228] For example, for type A consumables, when the type A consumable is located inside the roller structure, multiple tests are conducted on the nutrient solution infusion device at a flow rate of 700 mL / h to obtain multiple test currents under type A consumables. The average value of the test currents is calculated to obtain a current of 130 mA. Then the standard current range under type A consumables is (130 × 95% mA, 130 × 105% mA).

[0229] For example, for type B consumables, when the type B consumable is located inside the roller structure, multiple tests are conducted on the nutrient solution infusion device at a flow rate of 700 mL / h to obtain multiple test currents under type B consumables. The average value of the test currents is calculated to obtain a current of 140 mA. Therefore, the standard current range under type B consumables is (140 × 95% mA, 140 × 105% mA).

[0230] In some embodiments, the status information of the medical device is determined based on the operating status parameters of the driver and preset judgment rules, specifically including:

[0231] The operating current of the drive is compared with the standard current range of each consumable type. When the operating current of the drive is within the standard current range of a certain consumable type, the consumable type is output.

[0232] In some embodiments, the status information of the medical device is determined based on the operating status parameters of the driver and preset judgment rules, specifically including:

[0233] The operating current of the drive is compared with the standard current range of the target consumable type. When the operating current of the drive is not within the standard current range of the target consumable type, information about consumable type abnormality is output.

[0234] The target consumable type can be entered by the user when using the nutrient solution infusion device, or it can be automatically set when the nutrient solution infusion device enters a certain mode.

[0235] In the above technical solution, the tension of consumables of different types will be different, and the working current of the corresponding driving component will also be different. By detecting the working current of the working component and comparing the working current of the working component with the standard current range of a certain consumable type, it can be identified whether the consumable type is incorrect or whether the consumable type is being used incorrectly.

[0241] S1302. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0242] The preset judgment rules include standard torque value ranges for multiple consumable types. The tension of consumables of different types will vary, and the torque values ​​of the corresponding driving components will also be different.

[0243] For each type of consumable, when the consumable is located within the roller structure, the standard torque value range for each type of consumable is obtained by conducting multiple tests on the nutrient solution infusion device at a certain test flow rate.

[0244] For example, for type A consumables, when the type A consumable is located within the roller structure, multiple tests are conducted on the nutrient solution infusion device at a flow rate of 700 mL / h to obtain multiple test torque values ​​for type A consumables. The average value of the test torque values ​​is calculated to obtain a torque value of 117 mN.m. Therefore, the standard torque value range for type A consumables is (117 × 95% mN.m, 117 × 105% mN.m).

[0245] For example, for type B consumables, when the type B consumable is located within the roller structure, multiple tests are conducted on the nutrient solution infusion device at a flow rate of 700 mL / h to obtain multiple test torque values ​​for type B consumables. The average value of the test torque values ​​is calculated to obtain a torque value of 126 mN.m. Therefore, the standard torque value range for type B consumables is (126 × 95% mN.m, 126 × 105% mN.m).

[0246] In some embodiments, the status information of the medical device is determined based on the operating status parameters of the driver and preset judgment rules, specifically including:

[0247] The torque value of the drive component is compared with the standard torque value range for each consumable type. When the torque value of the drive component is within the standard torque value range for a certain consumable type, the consumable type is output.

[0253] Some embodiments of this application provide a detection method applied to a medical device, the method specifically including the following steps:

[0254] S1401. Obtain the operating status parameters of the driving component.

[0255] The operating status parameters of the drive unit include its operating current. The operating current of the drive unit is obtained when the medical device is running under load.

[0258] Among them, the preset judgment rules include the current range for consumable consistency evaluation, the length of consumables will affect the accuracy of medical equipment, and different lengths of consumables correspond to different operating currents of the drive components.

[0259] By installing standard-length consumables on a roller structure and conducting multiple tests on the medical device to obtain multiple currents, and then performing statistical analysis on these multiple currents to obtain the current range for consumable consistency assessment.

[0260] For example: Install standard consumables on the roller structure, and test the nutrient solution infusion device at a flow rate of 700 mL / h. Obtain the test current of multiple motors, calculate the average value of the test current of multiple motors as 125 mA, and set the consumable consistency evaluation current range as (125 mA - 125 × 0.02 mA, 125 mA + 125 × 0.02 mA).

[0261] The operating current of the drive unit is compared with the consumable consistency assessment current range. When the operating current of the drive unit is not within the consumable consistency assessment current range, the consumable length anomaly information is output.

[0262] In the above technical solution, the operating current of the drive component is different for different consumable lengths. By detecting the operating current of the drive component and comparing it with the current range of the consumable consistency assessment, it can be identified whether the length of the consumable is abnormal.

[0269] Among them, the preset judgment rules include the range of torque values ​​for consumable consistency assessment. The length of consumables affects the accuracy of medical equipment, and different consumable lengths correspond to different torque values ​​for the drive components.

[0270] By installing standard-length consumables on a roller structure and conducting multiple tests on the medical device to obtain multiple torque values, and by statistically analyzing these multiple torque values, the range of torque values ​​for consumable consistency assessment is obtained.

[0271] For example: Install standard consumables on the roller structure, and test the nutrient solution infusion device at a flow rate of 700 mL / h to obtain the test torque values ​​of multiple motors. Calculate the average value of the test torque values ​​of multiple motors as 112.5 mN.m, and set the range of consumable consistency evaluation torque values ​​as (112.5 mN.m - 112.5 × 0.02 mN.m, 112.5 mN.m + 112.5 × 0.02 mN.m).

[0272] The torque value of the drive component is compared with the range of consumable consistency assessment torque values. When the torque value of the drive component is not within the range of consumable consistency assessment torque values, consumable length anomaly information is output.

[0273] In the above technical solution, different consumable lengths correspond to different torque values ​​of the driving component. By detecting the torque value of the working component and comparing it with the range of torque values ​​for consumable consistency assessment, it can be identified whether the length of the consumable is abnormal.

[0275] Some embodiments of this application provide a detection method applied to a medical device, the method specifically including the following steps:

[0276] S1601. Obtain the operating status parameters of the driving component.

[0277] The operating status parameters of the drive unit include its operating current. The operating current of the drive unit is obtained when the medical device is running under no-load conditions.

[0278] For example: obtaining the operating current of the drive components of a nutrient solution infusion device when it is running without the roller structure.

[0279] S1602. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0280] The preset judgment rules include an open-circuit current threshold. The open-circuit current threshold is used to detect whether the medical device is working properly when running under no-load conditions.

[0281] For example, the nutrient solution infusion device is run at a flow rate of 700 mL / h and a corresponding rotation speed under no-load conditions. After multiple tests, the test currents of multiple motors are obtained, and the average value of the test currents of multiple motors is calculated to be 80 mA. The no-load current threshold is set to (80 mA + 80 × 0.02 mA).

[0282] If the operating current of the drive component is less than the no-load current threshold, it indicates that the equipment is operating normally under no-load conditions, and the system outputs a message indicating normal no-load operation. If the operating current is greater than or equal to the no-load current threshold, it indicates that the equipment is operating abnormally under no-load conditions, and the system outputs a message indicating abnormal no-load operation.

[0283] In the above technical solution, by detecting the working current of the working component and comparing the working current of the working component with the no-load current threshold, it is possible to identify whether the medical device is abnormal when running under no-load conditions.

[0285] Some embodiments of this application provide a detection method applied to a medical device, the method specifically including the following steps:

[0286] S1701. Obtain the operating status parameters of the drive component.

[0287] The operating status parameters of the drive components include their torque values. The torque values ​​of the drive components are obtained when the medical device is running under no-load conditions.

[0288] For example: obtaining the torque value of the drive component when the nutrient solution infusion equipment is running without the roller structure installed.

[0289] S1702. Determine the status information of the medical device based on the operating status parameters of the driving components and the preset judgment rules.

[0290] The preset judgment rules include a no-load torque value threshold. The no-load torque value threshold is used to detect whether the medical equipment is working properly when running under no-load conditions.

[0291] For example, the nutrient solution infusion device was run unloaded at a flow rate of 700 mL / h and a corresponding rotational speed. After multiple tests, the test torque values ​​of multiple motors were obtained. The average value of the test torque values ​​of multiple motors was calculated to be 72 mN.m, and the threshold value of the unloaded torque value was set to 72 × 1.05 mN.m. The flow rate and rotational speed satisfy the formula Q = 0.25 × n, where Q is the flow rate and n is the rotational speed.

[0292] Determine if the torque value of the drive component is within the no-load torque threshold. If it is less than the no-load torque threshold, it indicates that the equipment is operating normally under no-load, and outputs a message indicating normal no-load operation. If it is greater than or equal to the no-load torque threshold, it indicates that the equipment is operating abnormally under no-load, and outputs a message indicating abnormal no-load operation.

[0293] In the above technical solution, by detecting the torque value of the working part and comparing the torque value of the working part with the no-load torque value threshold, it is possible to identify whether the medical equipment is abnormal when running under no-load conditions.

[0294] It should be noted that the solutions involved in the above embodiments can be explained in combination with each other.
