Technical Field
[0001] This invention relates to the field of electronic circuit technology, and in particular to a consumable management system, control method, and vascular calcification treatment device. Background Technology
[0002] Vascular calcification is common in the elderly, especially those with chronic diseases such as hypertension and diabetes. These patients often require long-term medication and lifestyle interventions to control their condition. Through comprehensive treatment, most patients can experience effective symptom relief and control. However, because vascular calcification is an irreversible pathological process, it cannot be completely cured. The main goals of treatment are to slow disease progression, reduce complications, and improve patients' quality of life. With continuous advancements in medical technology and the development and promotion of innovative medical devices, the field of vascular calcification treatment will see more options and possibilities. In the future, more safe and effective treatment methods will emerge, providing patients with a better treatment experience and recovery outcomes.
[0003] In recent years, significant technological advancements have been made in the treatment of vascular calcification, with intravascular shockwave therapy being the most representative. This technique uses a pressure pump to pressurize a balloon and tightly adhere it to the vessel wall. After low-pressure expansion, the balloon delivers unfocused, 360° circumferential, pulsed mechanical energy to the calcified area. The acoustic pressure waves penetrate the coronary artery tissue, impacting and destroying the calcified lesion, leading to rupture of the intima and media. This technique is currently the only one effective for treating superficial, intermediate, and deep calcifications, and it only fragments the calcified lesion without damaging soft tissue, effectively reducing complications such as vascular dissection, perforation, and distal embolism that are common in traditional procedures. With continuous technological advancements and wider clinical application, the efficacy and safety of vascular calcification treatment have significantly improved. However, due to the complexity and diversity of vascular calcification lesions, personalized treatment plans still need to be developed based on the specific circumstances of each patient.
[0004] Shockwave catheters used for the treatment of vascular calcification are disposable consumables. Therefore, their use must be strictly controlled, and used consumables must be marked as expired to prevent the reuse of these consumables and the resulting significant safety risks to patients. On the one hand, as the number of treatments increases, the consumables also experience wear and tear, leading to a decline in their performance. On the other hand, the consumables can also become contaminated, and reuse would pose a threat to human health.
[0005] Currently, a common solution for active consumables is to use fuse blowing. This solution involves placing multiple fuses within the conduit and using a well-designed control circuit to read the status of each fuse, thereby determining the conduit's condition. At the start of use, a specific fuse-blowing circuit is triggered to blow a particular fuse, marking the conduit's condition as new or old. After use, another fuse-blowing circuit is triggered to blow a failed fuse, marking it as faulty. When the conduit is reconnected, the device can read the fuse status to determine the conduit's usage status, thus preventing the reuse of already used consumables. Some manufacturers also use a chip-based method for conduit validity marking. Data is written to a storage chip within the conduit and read back to determine its status. This method requires a storage chip, a driver circuit, and software for data read / write operations.
[0006] Currently, active consumables generally use fuses to determine their status, while some use memory chips. Using fuses requires a well-designed reading and fusing circuit to read and trigger the status of each fuse. When a conduit is connected, the device reads the status of each fuse and identifies and processes the conduit's status accordingly. When the conduit begins use, the device triggers the first fuse's fusing circuit to blow it. When the conduit is no longer in use, the device triggers the other fuse's fusing circuit to blow it. After a fuse blows, the conduit is marked as faulty. If the conduit is reconnected to the device, the device will detect the blown fuse and prevent further use of the conduit. This method avoids the reuse of active consumables, but it requires the use of low-current fuses and specific fusing circuits. The fusing process differs for each fuse, necessitating a unique circuit design for each. To ensure effective fuse fusing, a large current margin is required in the design, leading to complex hardware implementation and high costs. Furthermore, the fusing current of fuses requiring fusing is relatively low, around tens or hundreds of milliamps, and these low-current, low-power fuses are relatively expensive. Therefore, the overall cost of consumable identification and fusing processing is quite high, and the fusing status cannot be directly observed, requiring equipment for visualization. Using chips for consumable status management also presents relatively expensive storage chips and requires protective circuitry to prevent discharge interference. Summary of the Invention In view of this, the purpose of the present invention is to provide a consumable management system, control method and vascular calcification treatment device, which can realize the management of consumables and solve the problems of complex circuits and high costs in the prior art.

[0013] Secondly, embodiments of the present invention also disclose a control method for a consumable management system. The control method is applied to the aforementioned consumable management system. The control method includes: when detecting consumables, the control circuit provides a positive detection power supply voltage and a negative detection power supply voltage to the external terminal respectively; determining the consumable status based on the detection output signal generated by the control circuit, or determining the consumable status based on the light emission status of the first light-emitting diode and the second light-emitting diode; when the consumable status is determined to be that the consumable terminal is connected and is a new consumable, if the consumable terminal is subjected to failure processing, the control circuit further provides a positive failure power supply voltage and a negative failure power supply voltage to the external terminal respectively for failure processing of the first light-emitting diode and the second light-emitting diode.
[0014] In one embodiment, the determination of the consumable status based on the detection output signal generated by the control circuit, or the determination of the consumable status based on the luminous states of the first and second light-emitting diodes, further includes: determining whether the first light-emitting diode is in a non-failure state based on the detection output signal generated when the control circuit provides a positive detection power supply voltage or the luminous state of the first light-emitting diode; if the first light-emitting diode is determined to be in a non-failure state, then the consumable status is determined to be that the consumable terminal is connected; if the consumable status is determined to be that the consumable terminal is connected, determining whether the second light-emitting diode is in a non-failure state based on the detection output signal generated when the control circuit provides a negative detection power supply voltage or the luminous state of the second light-emitting diode; if the second light-emitting diode is determined to be in a non-failure state, then the consumable status is determined to be a new consumable.

The main power module is connected to the boost circuit and is connected to the processing module, the first power module, and the second power module via the buck circuit to provide power. The processing module is connected to the boost circuit and controls the boost circuit to output a pulse signal. The boost circuit is connected to the consumable electrode to form a high-voltage discharge circuit to release the pulse signal.
[0017] As described above, this invention discloses a consumable management system, control method, and vascular calcification treatment device. It uses light-emitting diodes (LEDs) to replace the fuses used for consumables, thus solving the problem of cumbersome and complex design of consumable fuse reading and processing circuits. Furthermore, the use of LEDs significantly reduces the cost of the consumable identification and processing section, and the fuse status is visually indicated by the light emission status. During consumable detection, the control circuit provides positive and negative detection power supply voltages to the external terminals. The consumable status is determined based on the detection output signal generated by the control circuit, or based on the light emission status of the first and second LEDs. When the consumable status is determined to be new, if the consumable is to fail, the control circuit also provides positive and negative failure power supply voltages to the external terminals for failure processing of the first and second LEDs. This method enables the management of disposable consumables at low cost and is easy to implement. Attached Figure Description

Based on the description of the present invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0025] The terms “first,” “second,” “third,” etc., are used merely to distinguish numerical values or elements with similar properties, rather than to indicate or imply relative importance or a specific order.
[0026] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.
[0027] Please see Figure 1 , Figure 1 This is a schematic diagram of a consumable management system according to an embodiment of the present invention. The consumable management system of this embodiment includes a consumable circuit 100 and a control circuit 200. The consumable circuit 100 is disposed at the consumable end, and the control circuit 200 is disposed at the device end. The consumable circuit 100 includes a first light-emitting diode (LED1) and a second light-emitting diode (LED2). The positive terminal of the first LED1 is connected to the negative terminal of the second LED2, and is also connected to an external terminal LED_COM. The negative terminal of the first LED1 is connected to the positive terminal of the second LED2 and grounded. The control circuit 200 provides a positive detection power supply voltage and a negative detection power supply voltage to the external terminal LED_COM, respectively. The control circuit 200 determines the consumable status based on the detection output signal generated by the control circuit 200, or based on the light emission status of the first LED1 and the second LED2. The control circuit 200 also provides a positive failure power supply voltage and a negative failure power supply voltage to the external terminal LED_COM, respectively, for failure handling of the first LED1 and the second LED2.
[0028] In one embodiment, such as Figure 1 As shown, the consumable circuit 100 also includes a buffer capacitor. The first end of the buffer capacitor is connected to the positive terminal of the first light-emitting diode LED1, and the second end of the buffer capacitor is connected to the negative terminal of the first light-emitting diode LED1. This buffer capacitor can be used to buffer the voltage in the circuit, providing a stable power supply voltage. When the power supply voltage changes suddenly, the buffer capacitor can quickly release or absorb charge to maintain voltage stability.
[0029] In one embodiment, the first light-emitting diode LED1 and the second light-emitting diode LED2 emit different colors. Therefore, the first light-emitting diode LED1 and the second light-emitting diode LED2 can be easily distinguished by their emission colors.
[0030] Specifically, the characteristics of a light-emitting diode are as follows: The light-emitting mechanism of a light-emitting diode (LED) is based on the electron-hole recombination process in semiconductor materials. Electrons in a semiconductor material jump from the conduction band to the valence band and recombine with holes, releasing energy as photons, thus emitting light. This process is called electroluminescence. The core of an LED is a semiconductor material, primarily composed of two types: P-type and N-type semiconductors. P-type semiconductors contain an excess of holes (positive charge carriers), while N-type semiconductors contain an excess of electrons (negative charge carriers). These two materials combine to form a PN junction. Current flows through the PN junction region. Electrons move from the conduction band of the N-type semiconductor to the valence band of the P-type semiconductor, recombinating with holes in the process. This recombination process releases photons, i.e., light emission. Under normal operating conditions, the current and voltage of an LED have a non-linear relationship. As the current increases, the luminous intensity of the LED increases, but the increase in current also leads to an increase in the forward voltage. If the current of the LED exceeds its rated value, it enters the overcurrent region. At this point, the temperature of the LED rises sharply, potentially leading to reduced light output, shortened lifespan, or even damage. Light-emitting diodes (LEDs) can withstand a certain range of reverse voltage. Under normal operating conditions, the reverse current should be very small, almost zero. When the reverse voltage applied to an LED exceeds its maximum withstand voltage, the PN junction of the LED breaks down, resulting in a large reverse current flowing through the LED.
[0031] Based on the characteristics of light-emitting diodes (LEDs), when the control circuit 200 provides different power supply voltages, such as positive detection power supply voltage, negative detection power supply voltage, positive failure power supply voltage, and negative failure power supply voltage, the first LED1 and the second LED2 operate in corresponding modes. The control circuit 200 also receives corresponding detection output signals, which can be used to determine the status of consumables and to handle the failure of new consumables. Its working process is as follows: First, when the control circuit 200 provides a positive detection power supply voltage to the external terminal LED_COM, this positive detection power supply voltage can be configured to enable the first light-emitting diode LED1 to light up, and the generated current does not exceed the rated value, ensuring that the first light-emitting diode LED1 lights up and will not be damaged by overcurrent. Moreover, the positive detection power supply voltage is configured to be a reverse voltage within a certain range that the second light-emitting diode LED2 can withstand. Then, the second light-emitting diode LED2 will not light up when receiving the positive detection power supply voltage and will not be damaged by breakdown. When the first light-emitting diode LED1 is in an undamaged state, part of the circuit in the control circuit 200 is grounded through the first light-emitting diode LED1 and is close to zero volts, which can be used by the control circuit 200 to generate a voltage signal, such as a low-level signal, to detect the output signal of the corresponding state. When detecting consumables, the control circuit 200 can provide a positive detection power supply voltage. The detection output signal generated by the control circuit 200 is a voltage signal corresponding to the corresponding state, such as a low-level signal, or the first light-emitting diode LED1 is lit. This can be used to determine the state of the consumables. That is, if the first light-emitting diode LED1 is determined to be in a non-failed state, the consumables are determined to be connected. Conversely, if the detection output signal generated by the control circuit 200 is another voltage signal corresponding to the corresponding state, such as a high-level signal, or the first light-emitting diode LED1 is not lit, this can be used to determine the state of the consumables. That is, if the first light-emitting diode LED1 is determined to be in a failed state, the consumables are determined to be not connected.
[0032] Then, when the control circuit 200 provides a negative detection power supply voltage to the external terminal LED_COM, this negative detection power supply voltage can be configured to enable the second light-emitting diode LED2 to light up, and the generated current does not exceed the rated value, ensuring that the second light-emitting diode LED2 lights up and will not be damaged by overcurrent. Moreover, the negative detection power supply voltage is configured to be a certain range of reverse voltage that the first light-emitting diode LED1 can withstand. Then, the first light-emitting diode LED1 will not light up when receiving the negative detection power supply voltage and will not be damaged by breakdown. When the second light-emitting diode LED2 is in an undamaged state, part of the circuit in the control circuit 200 is grounded through the second light-emitting diode LED2 and is close to zero volts, which can be used by the control circuit 200 to generate a voltage signal, such as a low-level signal, to detect the output signal of the corresponding state. When detecting consumables, the control circuit 200 can provide a negative detection power supply voltage. The detection output signal generated by the control circuit 200 is a voltage signal corresponding to the corresponding state, such as a low-level signal, or the second light-emitting diode LED2 is lit. This can be used to determine the state of the consumables. That is, if the second light-emitting diode LED2 is determined to be in a non-failed state, the consumables are determined to be new. Conversely, if the detection output signal generated by the control circuit 200 is another voltage signal corresponding to the corresponding state, such as a high-level signal, or the second light-emitting diode LED2 is not lit, this can be used to determine the state of the consumables. That is, if the second light-emitting diode LED2 is determined to be in a failed state, the consumables are determined to be old.
[0033] Next, when the control circuit 200 provides a negative failure power supply voltage to the external terminal LED_COM, this negative failure power supply voltage can be configured to make the second light-emitting diode LED2 light up, and the generated current exceeds the rated value, ensuring that the second light-emitting diode LED2 lights up and will eventually be damaged by overcurrent. Moreover, this negative failure power supply voltage is configured to be a certain range of reverse voltage that the first light-emitting diode LED1 can withstand. Then, the first light-emitting diode LED1 will not light up when receiving the negative failure power supply voltage and will not break down. Therefore, during the failure handling of new consumables, the control circuit 200 can provide a negative failure power supply voltage, the second light-emitting diode LED2 lights up and will eventually be damaged by overcurrent, realizing the failure handling of the second light-emitting diode LED2, while the first light-emitting diode LED1 is in an undamaged state of not lighting up.
[0034] Finally, when the control circuit 200 provides a positive failure power supply voltage to the external terminal LED_COM, this positive failure power supply voltage can be configured to make the first light-emitting diode LED1 light up, and the generated current exceeds the rated value, ensuring that the first light-emitting diode LED1 lights up and will eventually be damaged by overcurrent. Therefore, when the new consumable is used up and failure processing is performed, the control circuit 200 can provide a positive failure power supply voltage, the first light-emitting diode LED1 lights up and will eventually be damaged by overcurrent, thus achieving the failure processing of the first light-emitting diode LED1.
[0035] It should be noted that the present invention is not limited to the above. When determining the status of consumables, it is possible to first determine whether the consumable end is connected based on whether the first light-emitting diode LED1 is in a failed state, and then determine whether it is a new consumable based on whether the second light-emitting diode LED2 is in a failed state. Alternatively, it is possible to first determine whether the consumable end is connected based on whether the second light-emitting diode LED2 is in a failed state, and then determine whether it is a new consumable based on whether the first light-emitting diode LED1 is in a failed state. All of these are within the scope of protection of the present invention.
[0036] It should be noted that the present invention is not limited to the above-mentioned methods. When handling the failure of new consumables, the second light-emitting diode LED2 is first handled for failure, and then the first light-emitting diode LED1 is handled for failure when the new consumables are used up. Alternatively, the first light-emitting diode LED1 can be handled for failure first, and then the second light-emitting diode LED2 can be handled for failure when the new consumables are used up. All of these methods are within the scope of protection of the present invention.
[0037] In one embodiment, the control circuit 200 alternately provides positive and negative detection power supply voltages to the external terminal LED_COM at a time interval, and determines the consumable status based on the illumination state of the first LED (LED1) and the second LED (LED2). If the time interval is short and the first LED (LED1) and the second LED (LED2) are undamaged, they will be visible lit simultaneously, indicating that the consumable has been visually detected as new. This can also be used for continuous detection of the LEDs after the consumable status identification is completed. Furthermore, if the first LED (LED1) and the second LED (LED2) are set to display different colors, it is easier to distinguish between them, facilitating visual detection.
[0038] This embodiment of the consumable management system uses light-emitting diodes (LEDs) instead of fuses for consumables, thus solving the problem of cumbersome and complex design of consumable fuse reading and processing circuits. Furthermore, using LEDs significantly reduces the cost of the consumable identification and processing section, and the fuse status is visually indicated by the light emission. When detecting consumables, the control circuit 200 provides positive and negative detection power supply voltages to the external terminal LED_COM. The consumable status is determined based on the detection output signal generated by the control circuit 200, or based on the light emission status of the first LED (LED1) and the second LED (LED2). If the consumable status indicates that a new consumable has been connected, and the consumable has failed, the control circuit 200 also provides positive and negative failure power supply voltages to the external terminal LED_COM for failure processing of the first LED (LED1) and the second LED (LED2). This method enables the management of disposable consumables at low cost and is easy to implement.
[0039] The control circuit 200 of the present invention is supplied with different power supply voltages, such as positive detection power supply voltage, negative detection power supply voltage, positive failure power supply voltage and negative failure power supply voltage. This can be achieved by multiple power supplies with different voltages, or by power supply transformation. This application does not limit this.
[0040] Figure 2 This is a partial structural diagram of the control circuit of a consumable management system provided in an embodiment of the present invention.
[0041] In one embodiment, such as Figure 2 As shown, the control circuit 200 includes a processing module (not shown in the figure), a first analog switch U19B, a second analog switch U19C, a first reference positive power supply V_Ref1, a first reference negative power supply V_Ref2, a second reference negative power supply V_Ref3, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, and a voltage comparator OP1.
[0042] Among them, the control terminal IN1 of the first analog switch U19B is connected to the first control terminal U19_IN1 and is also grounded through the first resistor R1. The common terminal COM1 of the first analog switch U19B is connected to the external terminal LED_COM. The normally open terminal NO1 of the first analog switch U19B is connected to the first reference positive power supply V_Ref1 through the second resistor R2 and is also connected to the non-inverting input terminal of the voltage comparator OP1 through the third resistor R3.
[0043] Among them, the control terminal IN2 of the second analog switch U19C is connected to the second control terminal U19_IN2, and is also grounded through the fourth resistor R4. The common terminal COM2 of the second analog switch U19C is connected to the external terminal LED_COM. The normally open terminal NO2 of the second analog switch U19C is connected to the first reference negative power supply V_Ref2 through the fifth resistor R5, and is also connected to the inverting input terminal of the voltage comparator OP1 through the sixth resistor R6.
[0044] In this circuit, the non-inverting input of voltage comparator OP1 is connected to the second reference negative power supply V_Ref3 via resistor R7 (seventh resistor), and the inverting input of voltage comparator OP1 is connected to its output via resistor R8 (eighth resistor). The output of voltage comparator OP1 is connected to the status detection terminal of the processing module. Optionally, a capacitor C1 can be connected between the inverting input and output of voltage comparator OP1 for filtering and voltage regulation.
[0045] In one embodiment, such as Figure 2 As shown, the control circuit 200 also includes a first clamping diode D1, a second clamping diode D2, and a second reference positive power supply V_Ref4. The anode of the first clamping diode D1 is connected to the status detection terminal of the processing module, and the cathode of the first clamping diode D1 is connected to the second reference positive power supply V_Ref4. The cathode of the second clamping diode D2 is connected to the status detection terminal of the processing module, and the anode of the second clamping diode D2 is grounded. The first clamping diode D1 and the second clamping diode D2 can clamp and limit the output voltage, protecting the processing module receiving the signal at the device end.
[0046] In one embodiment, the first reference positive power supply V_Ref1 may be, but is not limited to, +5V, the first reference negative power supply V_Ref2 may be, but is not limited to, -5V, the second reference negative power supply V_Ref3 may be, but is not limited to, -5V, and the second reference positive power supply V_Ref4 may be, but is not limited to, +3V.
[0047] In one embodiment, the positive power supply terminal of voltage comparator OP1 can be connected to a positive power supply, such as a +12V power supply, and the negative power supply terminal can be connected to a negative power supply, such as a -12V power supply. Optionally, the positive power supply terminal of voltage comparator OP1 is grounded through a capacitor, and the negative power supply terminal of voltage comparator OP1 is grounded through another capacitor.
[0048] Figure 3 This is a schematic diagram of another part of the control circuit of the consumable management system provided in an embodiment of the present invention.
[0049] In one embodiment, such as Figure 3As shown, the control circuit 200 includes a processing module (not shown in the figure), a third analog switch U19D, a fourth analog switch U19E, a third reference negative power supply V_Ref5, a third reference positive power supply V_Ref6, a ninth resistor R9, and a tenth resistor R10. The control terminal IN3 of the third analog switch U19D is connected to the third control terminal U19_IN3 and is also grounded through the ninth resistor R9. The common terminal COM3 of the third analog switch U19D is connected to the external terminal LED_COM, and the normally open terminal NO3 of the third analog switch U19D is connected to the third reference negative power supply V_Ref5. The control terminal IN4 of the fourth analog switch U19E is connected to the fourth control terminal U19_IN4 and is also grounded through the tenth resistor R10. The common terminal COM4 of the fourth analog switch U19E is connected to the external terminal LED_COM, and the normally open terminal NO4 of the fourth analog switch U19E is connected to the third reference positive power supply V_Ref6.
[0050] Specifically, when consumables are not connected, the voltage at the non-inverting input of voltage comparator OP1 is greater than the voltage at the inverting input, and the output of voltage comparator OP1 is a positive voltage signal. After being clamped by the first clamping diode D1 and the second clamping diode D2, the output is high. When consumables are connected, the first control terminal U19_IN1 is pulled high, and channel 1 of the first analog switch U19B is turned on. The external terminal LED_COM is connected to node TH24. Node TH24 can be connected to the first reference positive power supply V_Ref1 through the second resistor R2. If consumables are connected and the first light-emitting diode LED1 is not in a faulty state, the voltage of node TH24 will be pulled low, and the voltage at the non-inverting input of voltage comparator OP1 will be pulled low. At this time, the voltage at the non-inverting input of voltage comparator OP1 is lower than the voltage at the inverting input of voltage comparator OP1, and the output of voltage comparator OP1 will be a negative voltage signal. After being clamped by the first clamping diode D1 and the second clamping diode D2, the output is low. When the processing module on the device detects a low level, it determines that a consumable has been connected. When the low level returns to a high level, it indicates that the consumable has been removed. During the consumable new / old detection, the second control terminal U19_IN2 is pulled high, which turns on channel 2 of the second analog switch U19C. The external terminal LED_COM is connected to node TH28. Node TH28 can be connected to the first reference negative power supply V_Ref2 through the fifth resistor R5. If the second light-emitting diode LED2 is not in a failed state when the consumable is connected, the voltage at node TH28 will be pulled high, and the voltage at the inverting input of voltage comparator OP1 will rise. The voltage at the inverting input of voltage comparator OP1 will be higher than the voltage at the non-inverting input of voltage comparator OP1, and the output of voltage comparator OP1 will output a negative voltage signal. After being clamped by the first clamping diode D1 and the second clamping diode D2, the output will be low. When the processing module on the device detects a low level, it determines that the consumable is new. If the detected level is high, it means that the second light-emitting diode LED2 has failed, and the consumable is a used consumable. Based on this, the various states of consumables can be analyzed and judged.
[0051] After the consumable status is identified, the first control terminal U19_IN1 and the second control terminal U19_IN2 can be pulled high at certain time intervals. If the first LED1 and the second LED2 are not faulty, they will light up and display different colors. If the first analog switch U19B and the second analog switch U19C switch frequently, the first LED1 and the second LED2 will light up simultaneously. The device can continuously detect the conduit status, and the user can also distinguish the status of the consumable by the different colors of the first LED1 and the second LED2.
[0052] When handling the failure of a new consumable, first disconnect all channels of the analog switches and temporarily suspend consumable status detection. If new consumable failure handling is required, pull the third control terminal U19_IN3 high, turn on channel 3 of the third analog switch U19D, and connect the second LED2 to the third reference negative power supply V_Ref5 (e.g., -12V), placing it in a forward-biased state. A large current will flow through LED2, causing its PN junction to fail and be damaged. Meanwhile, the first LED1 is in a reverse-biased state and can withstand a larger voltage, which is insufficient to break down its PN junction. When handling consumable failure after use, pull the fourth control terminal U19_IN4 high, turn on channel 4 of the fourth analog switch U19E, and connect the first LED1 to the third reference positive power supply V_Ref6 (e.g., +12V), placing it in a forward-biased state. A large current will flow through LED1, causing its PN junction to fail and be damaged. Based on this, failure handling can be performed on both LED1 and LED2.
[0053] Based on the same inventive concept, embodiments of the present invention also provide a control method for a consumables management system. Please refer to [link / reference]. Figure 4 , Figure 4 This is a flowchart illustrating a control method for a consumables management system according to an embodiment of the present invention. The control method for the consumables management system of this embodiment is applied to the aforementioned consumables management system, and its specific implementation can be found in the corresponding content of the consumables management system in the above embodiments. Figure 4 As shown, the control methods of the consumables management system include: S1, When detecting consumables, the control circuit provides positive detection power supply voltage and negative detection power supply voltage to the external terminal respectively, and determines the status of consumables based on the detection output signal generated by the control circuit, or determines the status of consumables based on the light emission status of the first light-emitting diode and the second light-emitting diode. S2, when the consumable status is determined to be new consumable connected to the consumable terminal, if the consumable terminal is to be processed for failure, the control circuit will also provide positive failure power supply voltage and negative failure power supply voltage to the external terminal respectively for the failure processing of the first light-emitting diode and the second light-emitting diode.
[0054] In one embodiment, determining the consumable status based on a detection output signal generated by the control circuit, or determining the consumable status based on the luminous states of the first and second light-emitting diodes, further includes: Based on the detection output signal generated when the control circuit provides a positive detection power supply voltage or the luminous state of the first LED, determine whether the first LED is in a non-failure state; if the first LED is determined to be in a non-failure state, then determine that the consumable status is consumable terminal connected. If the consumable status is determined to be consumable terminal connected, the detection output signal generated when the control circuit provides negative detection power supply voltage or the light emission status of the second light-emitting diode is used to determine whether the second light-emitting diode is in a non-failed state. If the second light-emitting diode is determined to be in a non-failed state, the consumable status is determined to be new consumable.
[0055] In one embodiment, determining the consumable status based on the luminous states of the first and second LEDs further includes: a control circuit alternately providing a positive detection power supply voltage and a negative detection power supply voltage to an external terminal at a time interval, and determining the consumable status based on the luminous states of the first and second LEDs.

[0057] Based on the same inventive concept, this invention also provides a vascular calcification treatment device. This device includes a device end, a connector, and a consumable end as described in the above embodiments. The device end is connected to the consumable end via the connector. The consumable end also includes consumable electrodes. The device end includes a main power module, a buck circuit, a boost circuit, and a control circuit as described in the above embodiments. The main power module is connected to the boost circuit and, through the buck circuit, to a processing module, a first power module, and a second power module for power supply. The processing module is connected to the boost circuit and controls the boost circuit to output pulse signals. The boost circuit is connected to the consumable electrodes to form a high-voltage discharge circuit to release the pulse signals. For specific implementation details, please refer to the corresponding content of the consumable management system in the above embodiments.
[0058] The consumable management system, control method, and vascular calcification treatment device provided in this invention use light-emitting diodes (LEDs) instead of consumable fuses, thus solving the problem of cumbersome and complex design of consumable fuse reading and processing circuits. Furthermore, using LEDs significantly reduces the cost of the consumable identification and processing section, and the fuse status is visually indicated by the light emission status. When detecting consumables, the control circuit provides positive and negative detection power supply voltages to the external terminals. The consumable status is determined based on the detection output signal generated by the control circuit, or based on the light emission status of the first and second LEDs. If the consumable status indicates that a new consumable is connected, and failure processing is required at the consumable end, the control circuit also provides positive and negative failure power supply voltages to the external terminals for failure processing of the first and second LEDs. This method enables the management of disposable consumables at low cost and is easy to implement.
