When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

[0045] The status detection of medical equipment such as infusion pumps and injection pumps can determine whether the medical equipment is abnormal. The present application aims to provide a method for detecting the status of medical equipment.

[0046] Embodiment 1

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

[0048] S101, obtaining operating status parameters of a driving component.

[0049] The operating state parameter of the driving component is used to characterize the operating state of the driving component.

[0050] In some embodiments, the operating status parameter includes at least one of the following: voltage value, current value, torque, and rotation speed.

[0051] S102: Determine status information of the medical device according to the operating status parameters of the driving component and preset judgment rules.

[0052] The preset judgment rule is a pre-determined judgment rule used to judge the status information of the medical device. The status information of the medical device is determined by inputting the running status parameter of the driving member into the preset judgment rule and determining the judgment result output by the preset judgment rule.

[0053] In some embodiments, the preset judgment rule includes at least one judgment range. If the operating state parameter of the driving member is within a preset judgment range, it is determined that the medical device is in a corresponding state.

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

[0055] In some embodiments, the preset judgment rule includes a preset application scenario and at least one judgment range. Since the operating status parameters of the driver may overlap and intersect in the judgment range in different application scenarios, it is easy to cause the medical device to be unable to distinguish the corresponding status information. Therefore, the user can pre-determine the application scenario in the medical device, and based on this application scenario, when the operating status parameter of the driver is within a certain judgment range, the corresponding working state of the medical device in this application scenario is determined. By adding the conditions of the preset application scenario, the accuracy of the medical device in judging the driver status information 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, and then the status information of the medical device is determined based on the operating status parameters of the driving component and preset judgment rules. In this way, the status information of the medical device can be determined and the status monitoring of the medical device can be realized, thereby ensuring the reliability of the medical device during use.

[0057] Embodiment 2

[0058] Some embodiments of the present application provide a detection method, which is applied to medical equipment and specifically includes the following steps:

[0059] S201, obtaining operating status parameters of a driving component.

[0060] The operating state parameter is related to the load driven by the driver, that is, when characterizing the operating state of the driver, the operating state parameter of the driver is used to characterize the operating state related to the load when the driver drives the load.

[0061] S202: Determine status information of the medical device according to the operating status parameters of the driving component and preset judgment rules.

[0062] Among them, since the operating state parameters of the driver are related to the load driven by the driver, the judgment result output by the preset judgment rule is also a judgment result related to the driver when driving the load, thereby determining the state information of the medical device when driving the load.

[0063] In the above technical scheme, the operating status parameters related to the load in the driving component are obtained to detect the operating status of the driving component when driving the load. Then, based on the operating status parameters of the driving component and 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, thereby ensuring the reliability of the medical device during use.

[0064] Embodiment 3

[0065] Some embodiments of the present application provide a detection method, which is applied to medical equipment and specifically includes the following steps:

[0066] S301, obtaining operating status parameters of a driving component.

[0067] The operating state parameter includes the working current of the driver, and a current sensor can be used to detect the working current of the driver and then output a voltage value, and the voltage value can be converted to output the working current of the driver. A current sensor can also be used to detect the working current of the driver and then output the working current of the driver.

[0068] S302: Determine the status information of the medical device according to the operating status parameters of the driving component and preset judgment rules.

[0069] The preset judgment rule includes a preset current range. When the working current of the driving component is within the preset current range, the operating state of the driving component is in a normal state. When the working current of the driving component is outside the preset current range, the operating state of the driving component is in an abnormal state.

[0070] The operating current of the driver can represent the load condition to which the driver is connected. When the connected load is normal, the operating current of the driver is within the preset current range. When the connected load is abnormal, the operating current of the driver is outside the preset current range.

[0071] More specifically, when the operating current of the driver is greater than the upper limit of the preset current range, it means that the output driving force of the driver is relatively large, and there may be additional resistance hindering the driver. When the operating current of the driver is less than the lower limit of the preset current range, it means that the output driving force of the driver is relatively small, and the load may not be properly connected to the load end of the driver.

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

[0073] When the load type does not change, the greater the rotation speed, the greater the working current corresponding to normal load driving, and the greater the lower limit value and upper limit value of the corresponding preset current range.

[0074] For example: when the speed of the driving part is 60 rpm, the corresponding working current is 100mA~110mA. When the speed of the driving part is 70 rpm, the corresponding working current is 120mA~130mA.

[0075] In the above technical solution, by detecting the working current of the driving component and determining the state information of the medical device when driving the load based on the working current of the driving component and the preset current range, the working state of the medical device when carrying the load can be determined, so as to ensure the reliability of the medical device during use. In addition, the working state detection of the medical device when carrying the load can be realized without additional mechanical sensors, which greatly simplifies the complexity of mechanical structure design.

[0076] Embodiment 4

[0077] Some embodiments of the present application provide a detection method, which is applied to medical equipment and specifically includes the following steps:

[0078] S401, obtaining operating status parameters of a driving component.

[0079] Among them, the operating state parameters include torque value.

[0080] The medical device also includes a force sensor, which is placed at the load end connected to the driving member, and is used to detect the torque of the load end connected to the driving member.

[0081] More specifically, the operating state parameters of the driving member are obtained, including:

[0082] The torque measurement voltage is obtained from the force sensor, and the torque value of the driving member is obtained according to the torque measurement voltage and the preset torque conversion coefficient. In this way, the torque value of the driving member 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 driving member according to the torque measurement voltage and the 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 member.

[0086] In some embodiments, a current sensor can be used to detect the working current of the driver and output a voltage value, and the voltage value can be converted to output the working current of the driver, and then the torque value of the driver can be calculated based on the working current of the driver 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 according to the operating status parameters of the driving component and preset judgment rules.

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

[0089] More specifically, when the torque value of the driving member is greater than the upper limit of the preset torque range, there may be additional resistance hindering the driving member. When the torque value of the driving member is less than the lower limit of the preset torque range, the load may not be properly connected to the load end of the driving member.

[0090] The preset torque range is also related to the load type. Different load types correspond to different preset torque ranges. The corresponding preset torque range can be set according to the load type, so that it can adapt to the working state detection when carrying different types of loads and improve the accuracy of the detection results.

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

[0092] Embodiment 5

[0093] Some embodiments of the present application provide a detection method, which is applied to medical equipment and specifically includes the following steps:

[0094] S501, obtaining operating status parameters of a driving component.

[0095] The operating state parameter includes a voltage value, and a current sensor can be used to detect the operating current of the driving component and convert the current value into a voltage value.

[0096] S502: Determine the status information of the medical device according to the operating status parameters of the driving component and preset judgment rules.

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

[0098] The operating voltage of the driver can represent the load condition to which the driver is connected. When the connected load is normal, the operating voltage of the driver is within the preset voltage range. When the connected load is abnormal, the operating voltage of the driver is outside the preset voltage range.

[0099] More specifically, when the operating voltage of the driver is greater than the upper limit of the preset voltage range, it means that the output driving force of the driver is relatively large, and there may be additional resistance hindering the driver. When the operating voltage of the driver is less than the lower limit of the preset voltage range, it means that the output driving force of the driver is relatively small, and the load may not be properly connected to the load end of the driver.

[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 the load based on the voltage value of the driving component and the preset voltage range, the working state of the medical device when carrying the load can be determined, so that the reliability of the medical device during use can be ensured. Dynamic detection of the load can be achieved without additional mechanical sensors, greatly simplifying the complexity of mechanical structure design.

The first end of each bridge arm reference resistor Rref is connected to the output end of the corresponding bridge arm amplifier 701, and the second end of the bridge arm reference resistor Rref is connected to the reference voltage Vref. By reading the output end 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 a working current of the motor.

The bridge arm current is filtered by the filtering circuit and output to the bridge arm amplifier 701. In this way, the noise signal in the bridge arm current is filtered out, the bridge arm current can be accurately obtained, and the bridge arm current is amplified and output, and then the amplified current is sampled to obtain the sampled voltage value as the operating state parameter of the driving component, thereby improving accuracy.

[0118] In some embodiments, the preset judgment rule includes at least one judgment range. If the operating state parameter of the driving member is within a preset judgment range, it is determined that the medical device is in a corresponding state.

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

[0120] In some embodiments, different types of loads require different driving forces, so multiple judgment ranges can be determined in advance, each judgment range corresponding to a type of load. In this way, the type of load carried 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 determined in advance, each judgment range corresponding to a state of the load.

[0134] Embodiment 7

[0135] Some embodiments of the present application provide a detection method, which is applied to a nutrient solution infusion device. The method specifically comprises the following steps:

[0136] S701, obtaining operating status parameters of a driving component.

[0137] The operating state parameter of the driving component includes the operating current of the driving component. The operating current of the driving component when the medical device is running under load is obtained.

[0138] For example: obtaining the working current of the driving component of the nutrient solution infusion device when the roller structure is installed and the consumables are installed in the roller structure.

[0139] S702: Determine the status information of the medical device according to the operating status parameters of the driving component and preset judgment rules.

[0140] The preset judgment rules include a current range when the consumables are in place and / or a current range when the consumables are dropped.

[0141] When the consumables are in the roller structure, multiple consumable in-place currents are obtained by performing multiple tests on the nutrient solution infusion device at a certain test flow rate, and the multiple consumable in-place currents are statistically analyzed to obtain the consumable in-place current range.

[0142] By performing multiple tests on the nutrient solution infusion device when the consumables are not located in the roller structure, multiple consumable shedding currents are obtained, and statistical analysis is performed on the multiple consumable shedding currents to obtain the consumable shedding current range.

[0143] For example: install the standard consumables on the roller structure, let the nutrient solution infusion equipment perform the infusion liquid test at a flow rate of 700mL / h, obtain the test current of multiple motors, calculate the average value of the test current of multiple motors to be 125mA, and set the in-place current range of the consumables to (125mA, 125mA+12.5mA).

[0144] For example: install the standard consumables on the roller structure, let the nutrient solution infusion equipment perform the infusion liquid test 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 to be 200mA, and set the in-place current range of the consumables to (200mA, 220mA).

[0145] In some embodiments, during the use period of the consumables, the operating current of the driving member is compared with the consumables in-place current range of the driving member, and when the operating current of the driving member is not within the consumables in-place current range, the consumables falling alarm information is output. When the operating current of the driving member is within the consumables in-place current range, the consumables in-place information is output.

[0146] In some embodiments, when the operating current of the driving component is less than the lower limit of the current range of the consumable, a consumable falling alarm message is output.

[0147] In some embodiments, during the use period of the consumables, the operating current of the driving member is compared with the consumables shedding current range of the driving member, and when the operating current of the driving member is within the consumables shedding current range, the consumables shedding alarm information is output. When the operating current of the driving member is not within the consumables shedding current range, the consumables in place information is output.

[0148] In some embodiments, during the use period of the consumables, the operating current of the driving member is compared with the current range of the consumables in place, and when the operating current of the driving member is within the current range of the consumables in place, the consumables in place information is output. When the operating current of the driving member is not within the current range of the consumables in place, the operating current of the driving member is compared with the current range of the consumables falling off of the driving member, and when the operating current of the driving member is within the current range of the consumables falling off, the consumables falling off alarm information is output.

[0149] In the above technical scheme, taking into account that there will be a big difference between the current of the driving component when the nutrient solution infusion pump is running with load and the current of the driving component when running without load, the working current of the driving component is obtained, and the working current of the driving component is compared with the current range of the consumables in place to determine whether the consumables are located in the roller structure. In this way, the status detection of whether the consumables in the nutrient solution infusion device are located in the roller structure is realized, without adding additional mechanical structure, simplifying the structure of the nutrient solution infusion pump.

[0151] Some embodiments of the present application provide a detection method, which is applied to medical equipment and specifically includes the following steps:

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

[0153] The operating state parameter of the driving component includes the operating current of the driving component. The operating current of the driving component when the medical device is running under load is obtained.

[0154] For example: obtaining the working current of the driving component of the nutrient solution infusion device when the roller structure is installed and the consumables are installed in the roller structure.

[0155] S802: Determine the status information of the medical device according to the operating status parameters of the driving component and preset judgment rules.

[0156] Among them, the preset judgment rules include the current range of the consumables in place. By performing multiple tests on the nutrient solution infusion equipment when the consumables are located in the roller structure, multiple consumables in place currents are obtained, and statistical analysis is performed on the multiple consumables in place currents to obtain the consumables in place current range.

[0157] The medical device also includes an in-situ detection component, which is arranged opposite to the roller structure and is used to detect whether the roller structure is installed on the driving component.

[0158] In some embodiments, determining the status information of the medical device according to the operating status parameters of the driving component and the preset judgment rules specifically includes the following steps:

[0159] Step a1: compare the working current of the driving component with the current range of the consumables of the driving component.

[0160] Step b1: when the working current of the driving component is not within the current range of the consumable in-place component, continue to obtain the detection result of the in-place detection component.

[0161] Step c1: When the in-situ detection component detects that the roller structure is in place, it outputs a consumables falling alarm message.

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

[0163] Step e1: when the operating current of the driving component is within the consumables in-place current range, output consumables in-place information.

[0164] In some embodiments, determining the status information of the medical device according to the operating status parameters of the driving component and the preset judgment rules specifically includes the following steps:

[0165] Step a2: comparing the operating current of the driving component with the consumables shedding current range of the driving component.

[0166] Step b2: when the working current of the driving component is within the consumables shedding current range, continue to obtain the detection result of the shedding detection component.

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

[0168] Step d2: When the fall-off detection component detects that the roller structure is not in place, it outputs abnormal fall-off information of the roller structure.

[0169] Step e2: when the operating current of the driving component is not within the consumables shedding current range, output consumables in place 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 arranged close to the roller structure. The roller structure is provided with a plurality of magnets 402 arranged along the circumference of the roller structure.

[0171] When the driving part of the nutrient solution infusion device drives the roller structure to rotate, each magnet 402 approaches the Hall sensor 401 in turn, and then moves away from the Hall sensor 401. When the Hall sensor 401 approaches the magnet 402, the intensity of the signal output by the Hall sensor 401 increases, and when the Hall sensor 401 moves away from the magnet 402, the intensity of the signal output by the Hall sensor 401 decreases, so that the Hall sensor 401 outputs a pulse signal. The number of pulse signals output by the Hall sensor 401 when the roller structure rotates one circle is related to the number of magnets 402.

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

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

[0174] The process of determining the status information of the medical device according to the operating status parameters of the driving component and the preset judgment rules specifically includes the following steps:

[0175] Step a2: compare the operating current of the driving component with the current range of the consumables of the driving component.

[0176] Step b2: when the operating current of the driving component is not within the current range of the consumable in-place component, continue to obtain the detection result of the Hall sensor 401.

[0177] Step c2: When the Hall sensor 401 outputs a pulse signal, it outputs the consumables falling alarm information.

[0178] Step d2: When the Hall sensor 401 outputs a high level or a low level, the roller structure in-position abnormality information is output.

[0179] Step e2: when the operating current of the driving component is within the consumables in-place current range, output consumables in-place 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 when installed on the driving member, causing the Hall sensor 401 to output a pulse signal, thereby realizing in-situ detection of the roller structure.

[0181] In the above technical solution, it is considered that if the roller structure is not installed on the driving part and the consumables fall off the roller structure, the driving part will rotate without load, so that the working current of the driving part is not within the current range of the consumables in place. In order to improve the accuracy of the detection result, the working current of the driving part is compared with the current range of the consumables in place. When the working current of the driving part is not within the current range of the consumables in place, it is further determined whether the roller structure is installed on the driving part. When the roller structure is installed on the driving part, it is determined that the consumables in the medical device are not located in the roller structure. Since there is no need to add additional mechanical structures, the structure of the nutrient solution infusion pump is simplified.

[0183] Some embodiments of the present application provide a detection method, which is applied to a nutrient solution infusion device. The method specifically comprises the following steps:

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

[0185] The operating state parameter of the driving component includes the torque value of the driving component. The torque value of the driving component when the medical device is running under load is obtained.

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

[0187] S902: Determine the status information of the medical device according to the operating status parameters of the driving component and preset judgment rules.

[0188] Among them, the preset judgment rules include the range of consumable in-place torque values. When the consumable is in the roller structure, multiple consumable in-place torque values ​​are obtained by allowing the nutrient solution infusion equipment to perform multiple tests at a certain test flow rate, and the multiple consumable in-place torque values ​​are statistically analyzed to obtain the range of consumable in-place torque values.

[0189] For example: install the standard consumables on the roller structure, let the nutrient solution infusion equipment perform liquid infusion test at a flow rate of 700mL / h, obtain the test torque values ​​of multiple motors, calculate the average value of the test torque values ​​of multiple motors to be 112.5mN.m, and set the in-place torque value range of the consumables to (112.5mN.m, 112.5×1.1mN.m).

[0190] For example: install the standard consumables on the roller structure, let the nutrient solution infusion equipment perform liquid infusion test at a flow rate of 1200mL / h, obtain the test torque values ​​of multiple motors, calculate the average value of the test torque values ​​of multiple motors to be 180mN.m, and set the in-place torque value range of the consumables to (180mN.m, 180mN.m+18mN.m).

[0191] During the use period of the consumables, the torque value of the driving member is compared with the consumables in-position torque value range of the driving member. When the torque value of the driving member is not within the consumables in-position torque value range, the consumables falling alarm information is output. When the torque value of the driving member is within the consumables in-position torque value range, the consumables in-position information is output.

[0192] In some embodiments, when the torque value of the driving member is less than the lower limit of the torque value range of the consumable, a consumable falling alarm message is output.

[0193] In the above technical scheme, considering that there will be a big difference between the torque value of the driving component when the nutrient solution infusion pump is running with load and the torque value of the driving component when it is running without load, by obtaining the torque value of the driving component, the torque value of the driving component is compared with the torque value range of the consumable in place to determine whether the consumable is located in the roller structure, thereby realizing the state detection of whether the consumable in the nutrient solution infusion device is located in the roller structure.

[0195] Some embodiments of the present application provide a detection method, which is applied to medical equipment and specifically includes the following steps:

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

[0197] The operating state parameter of the driving component includes the operating current of the driving component. The operating current of the driving component when the medical device is running under load is obtained.

[0198] For example: obtaining the working current of the driving component of the nutrient solution infusion device when the roller structure is installed and the consumables are installed in the roller structure.

[0199] S1002. Determine the status information of the medical device according to the operating status parameters of the driving component and preset judgment rules.

[0200] The preset judgment rule includes a consumable replacement current threshold. The consumable replacement current threshold is used to indicate the timing of replacing consumables. If the consumables are used for too long, the tension of the consumables will decay, and the decay of the tension of the consumables will reduce the accuracy of the infusion.

[0201] In some embodiments, unused consumables are installed in the roller structure, and multiple consumable replacement currents are obtained by performing multiple tests on the nutrient solution infusion device at a certain test flow rate, and the multiple consumable replacement currents are statistically analyzed to obtain the consumable replacement current threshold.

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

[0203] In some embodiments, the consumables are installed in the roller structure, and the working current of the driving member in the nutrient solution infusion device at different times and the infusion accuracy of the nutrient solution infusion device at different times are obtained by testing the whole life cycle of the consumables. The working current of the driving member corresponding to the infusion accuracy of the nutrient solution infusion device being lower than a preset threshold is used as the consumable replacement current threshold.

[0204] According to the operating status parameters of the driving component and the preset judgment rules, the status information of the medical device is determined, including:

[0205] The operating current of the driving component is compared with the consumable replacement current threshold, and when the operating current of the driving component is less than the consumable replacement current threshold, the consumable replacement reminder information is output.

[0206] In the above technical solution, considering the attenuation of the tensioning force of the consumables, the working current of the driving part will also decrease. By detecting the working current of the working part and comparing it with the consumable replacement current threshold, if it is less than the consumable replacement current threshold, it is determined that the tensioning force of the consumables has attenuated, thereby reminding the user to replace the infusion consumables.

[0216] In some embodiments, the consumables are installed in the roller structure, and the torque values ​​of the driving parts in the nutrient solution infusion device at different periods and the infusion accuracy of the nutrient solution infusion device at different periods are obtained by testing the consumables throughout their life cycle. The torque value of the driving part corresponding to the infusion accuracy of the nutrient solution infusion device being lower than a preset threshold is used as the torque value threshold for replacing the consumables.

[0217] According to the operating status parameters of the driving component and the preset judgment rules, the status information of the medical device is determined, including:

[0218] The torque value of the driving component is compared with the consumable replacement torque value threshold, and when the torque value of the driving component is less than the consumable replacement torque value threshold, consumable replacement reminder information is output.

[0225] S1202: Determine the status information of the medical device according to the operating status parameters of the driving component and preset judgment rules.

[0226] Among them, the preset judgment rules include standard current ranges of multiple consumable types. The consumable tensioning forces of different consumable types will be different, and the working currents of the corresponding driving parts will also be different.

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