[0028] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0029] The terms "first", "second", etc. in the technical solutions described in this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the disclosed embodiments described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0030] Unless otherwise stated, the term "plurality" means two or more.

[0031] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0032] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0033] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0034] Combination Figure 1 As shown, the embodiment of the present disclosure provides a method for monitoring a component of a medical device. The execution subject of the method may be a processor, and the method includes:

[0035] S101, the processor obtains proofreading authentication information after the current component is installed in the current device and reference authentication information after the original component is installed in the current device.

[0036] S102: When the verification authentication information is identical to the reference authentication information, the processor determines that the current state of the current component is the original state of the original component.

[0037] Among them, the proofreading authentication information includes the expression corresponding to the working parameter information related to the current component, and the reference authentication information includes the expression corresponding to the working parameter information related to the original component. The proofreading authentication information and the reference authentication information are both generated according to preset rules, and the reference authentication information remains unchanged when the original state of the original component remains unchanged.

[0038] In the disclosed embodiment, the proofreading authentication information includes an expression corresponding to the working parameter information related to the current component, and the reference authentication information includes an expression corresponding to the working parameter information related to the original component. When the original component is installed in the current device, the working parameter information related to the original component will not change during the operation of the device, that is, the reference authentication parameter does not change when the original state of the original component does not change, and the original state includes the component itself and / or the component installation state. When the original component is disassembled and reinstalled, or replaced with other components (for example, non-original components that obtain the identification information of the original component), differences will occur between the proofreading authentication information corresponding to the working parameter information and the reference authentication information. Therefore, if the current state of the current component is the original state of the original component, the proofreading authentication information after the current component is installed in the current device should be the same as the reference authentication information. If the current component is a non-original component that has copied the identification information of the original component or an original component that has been disassembled and reinstalled, the original state of the original component will be changed, causing differences in the working parameter information. By determining whether the proofreading authentication information after the current component is installed in the current device is the same as the reference authentication information, it is possible to determine whether the original component has been disassembled and replaced or abnormally disassembled and reinstalled, thereby monitoring the state of the original component and reducing safety risks of medical equipment.

[0039] Optionally, the current equipment includes large medical equipment; the target components include: a tube of a CT device, a detector of an imaging device, a lens of an optical device, etc.

[0040] Optionally, obtaining the proofreading authentication information after the current component is installed in the current device and the reference authentication information after the original component is installed in the current device includes: obtaining the working parameter information after the target component is installed in the current device, the working parameter information includes the physical parameter data of the target component, and / or the calibration data after the target component is installed in the current device; obtaining the target authentication information according to the preset rules based at least on the working parameter information; wherein the target component is the current component or the original component, and the target authentication information is the proofreading authentication information or the reference authentication information. In other words, if the target component is the current component, the proofreading authentication information is obtained, and if the target component is the original component, the reference authentication information is obtained.

[0041] Combination Figure 2 As shown, the embodiment of the present disclosure provides a method for generating target authentication information, including:

[0042] S201, the processor obtains the working parameter information of the target component after being installed in the current device.

[0043] S202: The processor obtains target authentication information based at least on the working parameter information and in accordance with preset rules.

[0044] In this embodiment, the working parameter information includes physical parameter data and correction data. According to the device principle of the target component, each target component has a set of different physical working parameters. After the target component is installed on the current device, the processor reads this set of parameters to generate physical parameter data. In addition, after the target component is installed on the current device, due to the physical deviation of the installation and the difference in the working environment, it is necessary to perform various correction operations on the target component to achieve physical accuracy. After the correction is completed, the processor will form a set of correction data based on the current installation state of the target component, that is, correction data that supports the target component to work on the current device. In this embodiment, since the working parameter information uses physical parameter data and correction data, the physical parameter data is related to the component itself. After the component is replaced, the difference in physical parameter data will be caused. The correction data is not only related to the component itself but also to the installation state of the component. After the component is disassembled, it will cause a difference in the correction data. Therefore, the method provided in this embodiment can prevent the counterfeiting of non-original components that copy the identification information of the original component, and can also prevent the disassembly and reinstallation of unauthorized original components. It should be noted that the authorized disassembly and reinstallation behavior generally re-acquires the reference authentication information after disassembly and reinstallation.

[0045] Optionally, obtaining physical parameter data of the target component includes: obtaining physical working parameters of the target component; generating working parameter data of the target component working on the current device according to the physical working parameters of the target component, and using the working parameter data as physical parameter data.

[0046] In this embodiment, after the target component is installed on the current device, the processor can obtain the physical working parameters of the target component and save the read physical working parameters as data files, which will be used as the physical parameter data of the target component working on the current device. In this embodiment, since the working parameter information uses physical parameter data, the physical parameter data is related to the component itself, and the replacement of the component will cause a difference in the physical parameter data, the method provided in this embodiment can prevent the counterfeiting of non-original components that copy the identification information of the original component, that is, prevent replacement.

[0047] Optionally, obtaining correction data after the target component is installed in the current device includes: performing a correction operation on the target component according to physical deviations of the target component installation and differences in the working environment; and generating correction data based on the installation state of the target component according to the correction operation.

[0048] In this embodiment, after the target component is installed in the current device, according to the physical deviation of the target component installation and the difference in the working environment, it is necessary to perform a correction operation on the target component. After the correction operation is completed, the data generated during the correction process is saved as a data file, and these files will be used as the correction data after the target component is installed in the current device. In this embodiment, since the correction data is related to the component itself and the installation state of the component, after the component is disassembled, even if the component is not replaced, the installation error before and after disassembly will cause a difference in the correction data, so the method provided in this embodiment can prevent unauthorized disassembly and reassembly, and of course, can also prevent replacement.

[0049] Optionally, at least based on the working parameter information, target authentication information is obtained according to preset rules, including: generating working parameter identification information according to the working parameter information; generating target authentication information according to the working parameter identification information based on preset rules; wherein the working parameter identification information includes physical parameter data identification information and correction data identification information, the physical parameter data corresponds to the physical parameter data identification information, and the correction data corresponds to the correction data identification information.

[0050] Combination Figure 3 As shown, the embodiment of the present disclosure provides another method for generating target authentication information, including:

[0051] S301, the processor obtains the working parameter information of the target component after being installed in the current device.

[0052] S302: The processor generates working parameter identification information according to the working parameter information.

[0053] S303: The processor generates target authentication information based on preset rules and working parameter identification information.

[0054] In this embodiment, it is necessary to generate corresponding physical parameter data identification information and correction data identification information according to the physical parameter data and correction data, and use the physical parameter data identification information and correction data identification information as working parameter identification information. Based on preset rules, target authentication information can be generated according to the working parameter identification information.

[0055] Optionally, the physical parameter data identification information and the correction data identification information may be set as hash values.

[0056] In this embodiment, a hash algorithm is used to process the physical parameter data and correction data, such as MD5, SHA-1 or SHA-256. These algorithms can generate a fixed-length hash value for the input data, and a slight change in the input data will result in a significant change in the hash value. The physical parameter data and correction data are taken as input, and their hash values ​​are calculated using the selected hash algorithm. For example, if the SHA-256 algorithm is used, the calculation process can be expressed as: physical parameter data identification information Hash1 = SHA-256 (physical parameter data); correction data identification information Hash2 = SHA-256 (correction data). Finally, the physical parameter data identification information and the correction data identification information are used as the working parameter identification information, and the key and algorithm after the original manufacturer's server authentication are used as preset rules to generate the target authentication information.

[0057] Optionally, the target component includes first device identification information, the current device includes second device identification information, and based at least on the working parameter information and according to preset rules, the target authentication information is obtained, including: based on the preset rules, the target authentication information is generated according to at least one of the first device identification information and the second device identification information and the working parameter identification information.

[0058] Combination Figure 4 As shown, the embodiment of the present disclosure provides another method for generating target authentication information, including:

[0059] S401, the processor obtains the working parameter information of the target component after being installed in the current device.

[0060] S402: The processor obtains first device identification information of the target component and second device identification information of the current device.

[0061] S403: The processor generates working parameter identification information according to the working parameter information.

[0062] S404: The processor generates target authentication information based on a preset rule and at least one of the first device identification information and the second device identification information and the working parameter identification information.

[0063] In this embodiment, when generating the target authentication information, in addition to the working parameter identification information of the target component, the first device identification information of the target component and / or the second device identification information of the current device are also used. In this way, the complexity of the target authentication information can be further enhanced, and the anti-disassembly or anti-replacement capability can be improved.

[0064] Optionally, obtaining the first device identification information of the target component includes: using an electronic tag SN (Serial Number) number of the target component as the first device identification information of the target component; or obtaining the first device identification information of the target component through an electronic tag device.

[0065] In this embodiment, after the target component is installed, the unique identification of the target component can be read as the first device identification information. According to the currently common types of target components, some target components have electronic tags SN numbers, which are directly read out and used; some target components do not have electronic tags themselves, and electronic tag devices will be installed later. Therefore, the unique identification SN number of the target component can be obtained as the first device identification information. In addition, the second device identification information of the current device refers to an information code that can uniquely identify the current device. Different manufacturers can have different generation algorithms, and store the generated second device identification information with the current device.

[0066] Optionally, the current component and the original component are both a tube, and the working parameter information includes physical parameter data of the tube, and / or correction data after the tube is installed in the current device; wherein the physical parameter data of the tube includes a grid voltage of the tube; and the correction data after the tube is installed in the current device includes one or more of mechanical correction data, filament correction data and calibration correction data.

[0067] In this embodiment, taking the tube of a CT device as an example, the physical parameter data of the tube includes: the grid voltage required when the tube is working. The correction data of the tube installation includes one or more of mechanical correction data, filament correction data and calibration correction data. Among them, mechanical correction requires adjusting the mechanical position of the tube to ensure that it is correctly aligned with other components of the CT device. Filament correction requires adjusting the filament position of the tube to ensure that the emission of X-rays is uniform and accurate. Calibration correction requires calibrating the output of the tube to ensure that the brightness and contrast of the image meet the standards.

[0068] Optionally, the proofreading authentication information after the current component is installed in the current device is obtained at a fixed period, or when the device is idle or powered on; the reference authentication information after the original component is installed in the current device is obtained after the original component is first installed in the current device.

[0069] In this embodiment, the current component used in the medical device can be monitored at a fixed period, such as every day or every hour, or at a specific time such as when the device is idle or turned on, to obtain the calibration authentication information of the current component after it is installed in the current device and compare it with the reference authentication information. The reference authentication information is generated after the original component is first installed in the current device, such as before the current device leaves the factory, based on the working parameter information of the original component after installation and the current device, as reference information for subsequent monitoring of the original component.

[0070] Optionally, the method for monitoring medical device components further includes: after obtaining the reference authentication information, verifying and authenticating the reference authentication information.

[0071] In this embodiment, after obtaining the reference authentication information, it is also necessary to verify and authenticate the reference authentication information to verify the authenticity of the original component and ensure that the original component is used to generate the reference authentication information.

[0072] Optionally, the reference authentication information is verified and authenticated, including: reporting the reference authentication information to the original manufacturer's server, which is verified and authenticated by the original manufacturer's server; or, reporting the data used to generate the reference authentication information to the original manufacturer's server, which is verified and authenticated by the original manufacturer's server; wherein the data used to generate the reference authentication information includes the working parameter identification information of the original component, and the first device identification information of the original component and / or the second device identification information of the current device.

[0073] In this embodiment, the reference authentication information or the data used to generate the reference authentication information is reported to the original manufacturer's server for verification and authentication. The reference authentication information, or the first device identification information of the original component and the second device identification information of the current device can be used for factory traceability confirmation. Different manufacturers can formulate different verification strategies according to their own management processes. For example, the first device identification information of the original component and the second device identification information of the current device are traced back and confirmed within the factory. The original manufacturer's server can check whether the first device identification information of the original component matches the manufacturer's records, and verify whether the second device identification information of the current device matches the device information recorded by the manufacturer. At the same time, it can also check the timestamp or other security marks to ensure the timeliness of the request. If all verifications pass, the server will generate an authentication result, which may be a successful authentication response, or a reference authentication information containing authentication information.

[0074] Optionally, the method for monitoring medical device components further comprises: executing protective control measures when the proofreading authentication information is different from the reference authentication information.

[0075] Combination Figure 5As shown, the embodiment of the present disclosure provides another method for monitoring medical device components, including:

[0076] S501, the processor obtains proofreading authentication information after the current component is installed in the current device and reference authentication information after the original component is installed in the current device.

[0077] S502: When the verification authentication information is identical to the reference authentication information, the processor determines that the current state of the current component is the original state of the original component.

[0078] S503: When the verification authentication information is different from the reference authentication information, the processor executes a protection control measure.

[0079] In this embodiment, if the proofreading authentication information is different from the reference authentication information, it means that the current component is not the original component or the original component has been disassembled without authorization. At this time, corresponding protection control measures can be executed to stop the operation of the equipment and protect the patient from the harm of unsafe radiation components.

[0080] The method for monitoring medical equipment components provided by the embodiments of the present disclosure integrates the physical parameters, correction parameters or their derived data information of the equipment components and one or more of the equipment component's own identification ID and the equipment component's own identification ID into the monitoring process of the equipment components, which can improve the reliability of the original component monitoring, solve the problem that the original software is difficult to identify the non-original components when the electronic tag of the original component is copied or the electronic tag module of the original component is physically migrated and reused, and can better lock the target component usage parameters and the guarantee capability of equipment compatibility, thereby improving the safety of equipment use. In addition, on large medical equipment, for components with individual differences in physical parameters or working parameters, it can be considered to integrate the differentiated working parameters and one or more of the component identification ID and the identification ID of the equipment into the monitoring process of the equipment components, so as to accurately detect whether the system uses the original components or whether the original components are disassembled without authorization.
