This application claims the priority of Chinese Patent Application No. 202111316464.X, entitled “CONSUMABLE MANAGEMENT SYSTEM, MANAGEMENT METHOD AND VASCULAR CALCIFICATION TREATMENT DEVICE”, filed on Nov. 8, 2021, the entire contents of which are incorporated by reference in this application.
The present application relates to the technical field of medical devices, and in particular to a consumable management system, a management method, and vascular calcification treatment device.
Vascular stenosis refers to the pathological process in which hydroxyapatite minerals are deposited in the vascular system. Due to abnormal lipid metabolism in human arteriovenous, coronary, peripheral, and intracranial blood vessels, the lipids in the blood are deposited in the originally smooth blood vessels. The intima gradually accumulates into atherosclerotic lipid plaques. Over time, the lipid plaques increase and calcify, resulting in narrowing of the vessel lumen, obstructing blood flow, and causing ischemia in downstream vessels and the body, resulting in corresponding clinical manifestations. Among them, 30% to 50% of vascular stenosis will have calcified plaques, and both coronary arteries and peripheral arteries may have calcified lesions, which is extremely difficult to treat. The current interventional surgery for the treatment of calcified plaque is generally “plaque atherectomy/rotary atherectomy”, but this surgical method is extremely difficult. Not only that, but rotary atherectomy can only deal with superficial calcification of intimal vessels, but is helpless for medial calcification, calcified nodules or severe calcification.
With the development of cardiovascular interventional technology, the techniques for targeting vascular calcified lesions are increasingly diversified. At present, it is attempted to use a shock wave treatment device consisting of a generator, a catheter, and a consumable balloon (a consumable electrode is arranged in the balloon), that is, a calcification treatment device. The balloon is placed in the lesion through the guide wire, and then the calcification is fragmented using ultrasonic technology to achieve the purpose of treatment. Generators and catheters can be used for patient treatment multiple times in a row, but the balloon is used as a disposable medical consumable, and the consumable balloon is in direct contact with the human body, so the safety of the consumable is also extremely important.
The applicant found that, in general, the selection, use and postoperative failure treatment of consumables are all manually performed by the operator, and there is no corresponding failure treatment mechanism for consumables and device themselves. At present, the effective control of consumables is mainly carried out through human methods, and errors will inevitably occur in human control. During the human control, if the consumables are not correctly distinguished, the used disposable consumables are connected to the device again, and there will be great safety hazards in treating patients when the equipment cannot distinguish the use of consumables. On the one hand, with the use of consumables for treatment, there is loss of consumables. Excessive use of consumables will make it difficult to guarantee their internal reliability, which will pose a threat to the safety and health of patients. On the other hand, it is difficult to guarantee the sterilization safety of consumables during secondary use, and the use of incompletely sterilized consumables will pose a serious threat to the health of patients, which will inevitably lead to medical safety accidents.
In view of the above technical problems, this application provides a consumable management system, management method and vascular calcification treatment device, which can distinguish and identify a disposable consumable, so that a secondary use of a consumable can be effectively avoided, thereby avoiding the secondary use that may cause safety risk, high stability and low cost.

Please refer to

Please refer to
Specifically, the control circuit 100 and the consumable circuit 200 may be connected through a connector, the fusing module 210 may be disposed at the consumable, the processing module 110, the first power supply module 120 and the second power supply module 130 may be disposed at the device, and the processing module 110 may be microcontroller. When the consumable is connected to the device, the control circuit 100 is connected to the consumable circuit 200, and the component of the consumable is connected to the corresponding equipment of the device (for example, the consumable electrode in the vascular calcification treatment device is connected to the output end of the booster circuit on the device), the processing module 110 outputs a detection trigger signal to the first power supply module 120, and the first power supply module 120 outputs the first power supply signal to the fusing module 210 after receiving the detection trigger signal, so as to be used for state detection of the fusing module 210, that is, to determine whether the fusing module 210 is in a disconnected state. When the processing module 110 determines that the state of the fusing module 210 is the connected state, that is, when the fusing of the fusing module 210 has not occurred yet, that is, the consumable is a new consumable, the processing module 110 then outputs a fusing trigger signal to the second power supply module 130, the second power supply module 130. The second power supply module 130 outputs a second power supply signal to the fusing module 210 after receiving the fusing trigger signal, so as to make the fusing module 210 in the disconnected state, that is, making the fusing of the fusing module 210 occurring. When the processing module 110 determines that the state of the fusing module 210 is disconnected after the consumable is connected and has not yet performed fusing processing, that is, when fusing has occurred, it is determined that the consumable is an old consumable, and there is no need to send a fusing trigger signal.
It should be noted that, after the processing module 110 determines the state of the fusing module 210, the processing module 110 stops outputting the detection trigger signal.
In one embodiment, the processing module 110 controls the second power supply module 130 to output the second power supply signal to the fusing module 210 when determining that the state of the fusing module 210 is connected state and triggering pulse treatment, so as to make the fusing module 210 in the disconnected state.
Specifically, in order to avoid misdiagnosing the new consumable that has been connected but not used for treatment as the old consumable, and the problem of fusing the fusing module 210 occurs. For example, in the vascular calcification treatment device, the consumable is connected to the device, but the device does not send high voltage pulse to the consumable electrode of the consumable, that is, the consumable as not been used for treatment in fact, but the consumable is misjudged as an old consumable. In the present embodiment, when the processing module 110 determines that the state of the fusing module 210 is in the connected state and the processing module 110 triggers pulse treatment (that is, when the processing module 110 triggered the pulse treatment is detected or the processing module 110 sent the pulse treatment signal is detected), the processing module 110 outputs the trigger fusing signal to the second power supply module to control the second power supply module 130 to output the second power supply signal to the fusing module 210 to make the fusing module 210 in the disconnected state.
In one embodiment, after the processing module 110 output the fusing trigger signal to the second power supply module 130, so that the second power supply module 130 outputs the second power supply signal to the fusing module 210, so that the fuse module 210 is in the disconnected state, the processing module 110 outputs the detection trigger signal to the first power supply module 120 again. So that the first power supply module 120 outputs the first power supply signal to the fuse module 210 to determine whether the fuse module 210 is in the disconnected state.
Please refer to
Wherein, the processing module 110 is connected to the second end of the fuse FU, and is used for obtaining a monitoring signal, which is used for judging the state of the fusing module 210.
Specifically, when the first power supply signal is output to the fusing module 210, if the consumable is a new consumable at this time, the first power supply signal passes through the fuse FU and the resistor R to the power ground, and the voltage signal amplitude of the first power supply signal is low, and the current flowing through the fuse FU cannot fuse the fuse FU. At this time, the monitoring signal obtained by the processing module 110 is at a high level, and the processing module 110 considers it to be a new consumable after detecting the high-level signal. If the consumable is a used consumable, the fuse FU in the fusing module 210 has been fused, and the current cannot flow through the fuse FU, and the monitoring signal obtained by the processing module 110 is at a low level. Therefore, the use state of the consumable can be distinguished by monitoring the difference between the high level and low level of the signal.
In one embodiment, after the detection of the consumable is completed, the processing module 110 no longer detects the monitoring signal, and at the same time, the processing module 110 controls the first power supply module 120 to stop outputting.
Please refer to
Wherein, the first switch K1 switches on the voltage source Us and the fusing module 210 when receiving the detection trigger signal, so that the voltage source Us outputs the first power supply signal to the fusing module 210. When the second switch K2 receives the fusing trigger signal, it switches on the current source Is and the fusing module 210, so that the current source Is outputs the second power supply signal to the fusing module 210.
Please refer to
Wherein, the processing module 110 outputs a detection trigger signal to the first power supply module 120 when receiving a feedback signal corresponding to the third power supply signal output by the third power supply module 140 through the connection module 220.
Specifically, the connection module 220 may include, for example, a wire for connecting the output terminal of the third power supply module 140 and the feedback signal pin of the processing module 110, and the connection module 220 provided at the consumable is connected to the third power supply module 140 and the processing module 110, the pin of the processing module 110 receive a feedback signal corresponding to the third power supply signal output by the third power supply module 140, and the processing module 110 determines that the consumable has been connected to the device according to the feedback signal. For example, when the consumable is not connected, the feedback signal is a low-level signal, and after the consumable is connected, the feedback signal will be a high-level signal. Similarly, after the consumable is disconnected from the device, the feedback signal pin will become low level. After judging that the consumable is connected, the device starts to detect the state of the fusing module 210 in the consumable, and distinguishes whether the connected consumable is a new or an used.
In one embodiment, the processing module 110 is further configured to decrement the remaining treatment number of the consumable according to the pulse treatment control signal.
Specifically, the processing module 110 outputs a fusing trigger signal to the second power supply module, so as to control the fusing module 210 to set a remaining treatment number to an effective maximum after it is confirmed that the fusing module 210 is effectively fusing. The device can perform pulse treatment according to the displayed remaining treatment number. With each pulse treatment of the user, that is, when the processing module 110 receives the pulse treatment control signal, the remaining treatment number is reduced by one until the remaining treatment number is reduced to zero.
In one embodiment, the control circuit 100 further includes a backup power supply, which is configured to supply power to the processing module 110 when the processing module 110 is in a low power consumption state.
Specifically, after the main power supply of the device that supplies power to the processing module 110 is turned off, the processing module 110 triggers a low power consumption state, and the backup battery supplies power to the processing module 110. The processing module 110 is not completely powered off, and the remaining treatment number of the consumable can still be memorized, so that when the consumable is used again, the processing module 110 can continue to perform pulse treatment according to the remaining treatment number.
In one embodiment, the control circuit 100 further includes an alarm module, and the processing module 110 is connected to the alarm module, and is configured to control the alarm module to give an alarm prompt when the remaining treatment number of the consumable is 0.
Specifically, the alarm module can be a buzzer and/or an LED light, etc.
In summary, the consumable end management system provided by the embodiment of the invention can distinguish and identify the disposable consumable so as to effectively avoid the secondary use of consumables, and then avoid the security risks that may be caused by the secondary use, and also carry out effective security control of the use of consumables, with high stability and low cost.
