Description
Technical Field
The invention belongs to the technical field of medical equipment, and particularly relates to an equipment management system carrying product information.
Background
With the development of science and technology and the improvement of living standard, the requirements of people on medical health and medical services are higher and higher. Simple disease treatment has not met the needs of patients and physicians who require more precise disease treatment and more efficient postoperative management. Post-operative management of patients is particularly important for the cardiac implant industry, where once implanted, the devices will work in the body for 15 to 20 years or more. The traditional postoperative management method is that a patient visits to a hospital every 3 to 6 months, and a doctor views and adjusts the physiological state of the patient and the working state of equipment through a program controller. At present, most doctors and patients do not meet the postoperative management mode of once every 3 to 6 months, and more hopefully, the doctors and the patients can monitor physiological information of the patients and working states of equipment in real time or in real time, so that problems can be solved in time, medical treatment can be carried out in time, and risks can be reduced.
In order to better serve patients and doctors, all implanted device manufacturers convert the research, development and production of single implanted devices into the management and design of the implanted devices of the system, combine cross-domain technologies such as a communication network and the Internet and use the technologies such as 5G, big data analysis, cloud service and high concurrency to realize remote follow-up and remote monitoring, and achieve the purpose of monitoring the states of the patients and the devices in real time or in real time. In the whole patient implanted device management system, a plurality of user groups and terminal device products used by each group are involved, for example, the terminal devices used by patients and family members thereof are generally called as patient terminals, devices used by doctors are provided with program controllers and clinical terminals, and different user groups and terminal devices are connected by means of basic product information (serial numbers of the devices, models of the devices and the like) of the heart implanted devices. The patient binds with the patient terminal through implantation equipment product information, and the doctor adds the patient in patient management system through clinical terminal and implantation equipment product information, and the doctor inputs implantation equipment product information and generates the implantation information of patient according to other information through programme-controlled appearance simultaneously. Such as the CareLink system of medton, the patient management system of boston science, and the Home Monitor system of hundreds of forces all provide similar functions.
At present, the basic product information of the heart implantation equipment is stored in a traditional mode such as paper nameplates or printing on the surface of the heart implantation equipment, and the traditional mode is difficult to meet the requirements of patients and doctors. The traditional storage mode is that basic information of a product is visually displayed, and any person can extract effective information from the basic information, so that information of the implanted equipment of a patient can be leaked. In addition, the traditional storage mode is more unfavorable for product information to circulate in each terminal product device in the patient implantation device management system, and the patient and the doctor need to manually enter the implantation device product information, so that the problems of tedious entry, low efficiency, easy error, insecurity and the like exist. Also, a physician may manage implant device information using a programmer or implant device management system in an operating room, sterile environment, and with medical gloves, which may be particularly inconvenient and error prone if the implant device information is also entered manually.
With the development of information technology and the popularization of bar code technology, the application of two-dimensional codes is more and more extensive, and the fields such as industry, consumption, medical treatment and the like are all related. A large amount of information can be concentrated and stored in a two-dimensional code, and a user can easily obtain the information only by general or specific portable code scanning system equipment when checking the information, and the information is not required to be manually input, so that the accuracy and the efficiency are high.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the detailed description and specific examples, while indicating the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Aiming at the problems of complicated input, low efficiency, high error rate, insecurity, difficult operation in a sterile environment and the like of the existing product information manually input into implanted equipment, the embodiment of the invention provides an equipment management system carrying the product information.
Fig. 1 is a schematic structural diagram of a device management system carrying product information according to an embodiment. As shown in fig. 1, the device management system includes an implanted device 110, a manufacturer terminal 120, a patient terminal 130, a doctor terminal 140, a program controller 150, and a server 160, wherein the implanted device 110 is provided with a two-dimensional code carrying product information; the manufacturer terminal 120 is configured to manage the implant device 110, scan and decode the two-dimensional code, upload the obtained product information to the server 160, verify the product information, and store the product information; the patient terminal 130 is used to bind the implant device 110 with the patient, acquire product information by scanning and decoding the two-dimensional code, register patient information, and verify that the product information and the patient information are bound based on the binding information of the server 160; the doctor terminal 140 is used for managing patients, acquiring product information by scanning and decoding the two-dimensional code, and verifying the addition of patients to be managed based on the patient information of the server 160; the program controller 150 is used for managing patient implantation information, scanning and decoding the two-dimensional code to obtain product information, generating patient implantation information with other input information of the patient, and uploading the patient implantation information to the server 160 for storage; the server 160 is used for storing product information, patient information, and patient implantation information, and performing product information verification, binding information verification, and patient information verification.
In the embodiment, the product information of the implantation equipment is stored by adopting the static code of the two-dimensional code, the two-dimensional code corresponds to the stored product information one by one, the product information carried by the two-dimensional code once generated can not be changed, if the product information needs to be changed, the two-dimensional code needs to be regenerated, based on the characteristic of the two-dimensional code, the product information can be obtained by scanning and decoding the two-dimensional code, and the safety and the reliability of the product information can be realized.
The two-dimensional code installed on the implanted device 110 is implemented by a two-dimensional code encoding system, which may be a general software or a customized software, and may be run on a computer side or a mobile device side. The two-dimensional code coding system is provided with a human-computer interaction interface for a user to input product information of the implanted device, such as the brand, the model, the serial number, the shelf date of the device, communication device information (MAC address and name of the low-power Bluetooth device) with unique identification and the like. After a user inputs product information, the two-dimensional code coding system sequentially encrypts, combines and codes the product information to generate a two-dimensional code. The generated two-dimensional code is bound with the corresponding implant device 110 and displayed, for example, the two-dimensional code is permanently printed on the surface of the implant device 110 or the two-dimensional code is made into a card and packaged together with the implant device 110. The manufacturer terminal 120, the patient terminal 130, the doctor terminal 140 and the program controller 150 decode the two-dimensional code by using the embedded two-dimensional code decoding system to acquire product information by scanning the two-dimensional code on the implanted device 110.
The two-dimensional code encoding system corresponds to the two-dimensional code decoding system. The two-dimension code coding system encrypts and combines the product information of the implanted equipment according to a certain rule and generates a two-dimension code. And the two-dimensional code decoding system analyzes and decrypts the two-dimensional code information according to the coding rule of the two-dimensional code coding system.
Fig. 6 is a schematic flowchart of two-dimensional code encoding according to an embodiment. As shown in fig. 6, the encoding process of the two-dimensional code is as follows: acquiring product information input by a user, and verifying the product information according to basic rules of the product information, wherein the verification mainly verifies whether the product information is complete and accurate, and the flow is ended if the verification fails; after the verification is passed, randomly appointing an encryption algorithm, randomly generating a secret key according to the product information, encrypting the product information by utilizing the appointed encryption algorithm and the secret key to obtain a ciphertext, combining the ciphertext, the secret key and the encryption algorithm according to a certain rule, and then generating a two-dimensional code for the obtained combined sequence information, wherein the coding process is ended.
In the embodiment, when the ciphertext, the key and the encryption algorithm are combined, the combination mode is also restricted, and the ciphertext, the key, the encryption algorithm and the combination mode form a combined sequence; wherein, the combination mode restricts the position of at least 1 of the encryption algorithm, the secret key and the ciphertext in the combination sequence. It can be understood that in the combination sequence, bytes at certain positions constrain the combination mode, and the encryption algorithm, the key and the ciphertext are arranged at corresponding positions in the combination sequence according to the combination mode.
In one possible implementation, the combination mode includes a specified key insertion mode in the ciphertext, and the keys are inserted in the ciphertext according to the specified insertion mode to form the combination sequence. And the key and the ciphertext are combined in an interleaving mode, so that the decoding difficulty of the combined sequence is increased, and the safety of product information is improved.
In one possible embodiment, the first few bytes of the combined sequence include the encryption algorithm, key length, and combination mode information, which make up the random header information of the combined sequence. The random header information is adopted, so that each combined sequence is different, and the decoding complexity of the combined sequence is increased.
In one possible implementation, the cipher text and the key in the combined sequence are indexed differently, and the encryption algorithm, the key length and the combination mode information are not indexed, so that the indexing mode can quickly separate the key and the cipher text from the combined sequence.
In the embodiment, when the scanning two-dimensional code is decoded, the key, the ciphertext and the encryption algorithm are separated after the combined sequence is obtained, and the product information is obtained through the product information verification of the server after the encryption algorithm is adopted and the ciphertext is decrypted according to the key. Fig. 7 is a flowchart illustrating two-dimensional code decoding according to an embodiment. As shown in fig. 7, the decoding process of the two-dimensional code is as follows: acquiring a combination sequence stored by the two-dimensional code through scanning, reversely separating a ciphertext, a key and an encryption algorithm from the combination sequence, and ending the process if the separation fails; after the separation is successful, the separated encryption algorithm and the key are used for decrypting the ciphertext, and if the decryption fails, the process is ended; after the ciphertext is decrypted, extracting the product information, and ending the process if the extraction fails; and after the product information is extracted, verifying the product information until the two-dimensional code decoding process is finished.
There are many combinations of ciphertexts, keys and encryption algorithms and separation methods corresponding to the combinations, and fig. 8 to 10 exemplarily show key arrangement, cipher text arrangement, and combination sequence arrangement. In fig. 8, the key length is m +1 bytes, and the index values are 0 to m. In fig. 9, the ciphertext has a length of n +1Byte and index values of 0 to n. The length of the combined sequence shown in fig. 10 is the sum of the lengths of other information such as the key length, the ciphertext length, the type of encryption algorithm, and the combination method. In the combination sequence, the key and the ciphertext are mainly combined, when the ciphertext and the key are combined, additional combination mode information is required to indicate the combination relation of the ciphertext and the key, and actually, the key information is inserted into the ciphertext content according to a certain rule. The encryption algorithm type and combination may take one or more bytes in the combined sequence.
In the embodiment, let AT be an encryption algorithm type (e.g. 0 for AES128, 1 for AES256, etc.), KL be a key length, BP be a start insertion position of the key in the ciphertext content, and SD be an insertion interval position of the key in the ciphertext. The combination sequence information arrangement formed by the ciphertext, the key and the encryption algorithm is as shown in fig. 10, the first four bytes are fixed as AT, KL, BP and SD, then the ciphertext and the key are combined and arranged, the first four bytes do not perform index calculation, and the index is 0 from the fifth Byte and are accumulated in sequence. Firstly, determining the insertion position of a first Byte (Byte) of a key according to BP, starting storage from an index 0, sequentially storing ciphertext contents if the index is not BP, and storing the first Byte of the key if the index is BP; continuously determining the insertion position of the second Byte of the key, continuously adding and storing the index, if the index is not BP + SD, sequentially storing the cipher text content, and if the index is BP + SD, storing the cipher text content into the second Byte of the key; and accumulating the key information in sequence until the key information is completely stored, wherein the indexes of the key information are BP, BP + SD, BP +2SD, … … and BP + KL × SD.
In the embodiment, the cryptograph, the key and the encryption algorithm are separated and combined correspondingly. And after the combined sequence of the ciphertext, the key and the encryption algorithm is obtained, the ciphertext, the key and the encryption algorithm are separated. Firstly, the head of the cipher text and the key combination information, namely the first four bytes are analyzed, the first Byte is an encryption algorithm type AT, the second Byte is a key length KL, the third Byte is an initial position BP of the key stored in the content, and the fourth Byte is an interval position SD of the key storage. After the header parsing is completed, the parsed content separates the ciphertext and the key according to the header information. Recalculating the index value of the fifth Byte to be 0 and accumulating indexes in sequence, if the index value is not equal to BP, BP + SD, BP +2SD, … … and BP + KL SD, storing the index value as ciphertext content in sequence, otherwise, storing the cipher key content in sequence. When the ciphertext and the secret key are combined and arranged, in order to increase the cracking difficulty, AT, KL, BP and SD can be randomly generated, so that the head information in the stored information of each product is inconsistent.
According to the encryption method, each product can have different encryption algorithms and keys, the encryption algorithm, the key information and the ciphertext information are simultaneously stored in the encryption information of the product, and the decryption party does not need to store the keys and directly obtains the encryption algorithms and the key information from the combined sequence.
FIG. 2 is a flowchart illustrating a process of identifying product information by a vendor terminal according to an embodiment. As shown in fig. 2, the vendor terminal 120 is typically a general-purpose or customized mobile device with camera, 5G or WIFI functionality, and must have specific software installed or embedded therein. The manufacturer terminal 120 scans the two-dimensional code on the implanted device 110, identifies the product information according to the two-dimensional code decoding process, and if the information identification fails, the identification process is ended, and the device addition fails. If the product information identification is successful, the product information is transmitted to the server 160 through 5G or WIFI, the server 160 verifies the product information after receiving the product information, specifically, whether the implanted device belongs to the device manufacturer corresponding to the manufacturer terminal for production is verified according to the product information, whether the product information is stored in the server 160 is verified, and the like. Server 160 stores the implant device product information into server 160 after the product information verification is passed, so that implant device 110 is successfully added.
Fig. 3 is a flow diagram illustrating identification of product information by a patient terminal according to an embodiment. As shown in fig. 3, patient terminal 130 is typically a general purpose or customized mobile device with camera, 5G or WIFI capability that must have specific software installed or embedded. Meanwhile, the patient terminal 130 also has a human-computer interaction interface for the user to input other information. The patient terminal 160 scans the two-dimensional code on the implanted device 110, identifies the product information through the above two-dimensional code decoding process, and if the information identification fails, the identification process is terminated, and the binding between the patient and the implanted device 110 fails. If the information identification is successful, the product information of the implanted device 110 is displayed and the patient is prompted to enter patient information such as a user ID (which may be a unique character text, a telephone number, a mailbox address), a password, a communication method, and the like. After the patient information is confirmed without error, the patient terminal 130 transmits the product information and the user basic information to the server 160 through 5G or WIFI, and applies for a patient account to the server 160. The server 160 performs binding information verification on the product information and the patient information after receiving the information, specifically verifies whether the received product information has been stored in the server, verifies whether the patient information has been registered, and the like. After the server 33 is verified by the binding information, a patient account is created for the patient by using the current product information and the patient information, and after the account is created, the patient, the implanted device and the account are bound and stored.
Fig. 4 is a flowchart illustrating the product information identification process performed by the doctor terminal according to an embodiment. As shown in fig. 4, the doctor terminal 140 is typically a general-purpose or customized mobile device with camera, 5G or WIFI functionality, and must have specific software installed or embedded therein. Meanwhile, the doctor terminal 140 also has a man-machine interface for the user to input basic information of the patient. The doctor terminal 140 scans the two-dimensional code on the implant device 110, identifies the product information of the implant device through the above two-dimensional code decoding process, and if the information identification fails, the identification process is ended, and the addition of the patient fails. The information recognition displays product information and prompts the doctor to enter patient information, such as patient name, contact details, patient account, and the like. After the patient information input is confirmed without error, the doctor terminal 140 transmits the product information and the patient information to the server 160 through 5G and WIF, and applies for the addition of the patient to the server 160. The server 160 verifies the patient information for the product information and the patient information after receiving the information, specifically, verifies whether the received product information has been stored in the server 160, verifies whether the patient information has been stored in the server 160, and adds the patient information to the patient management account of the doctor terminal 140 after the server 160 passes the patient information verification.
Fig. 5 is a schematic flowchart of the process of identifying product information by the program controller according to an embodiment. As shown in fig. 5, the programmer 150 is typically a general purpose or customized mobile device with camera, 5G or WIFI capability, and specific software must be installed or embedded. The program controller 150 scans the two-dimensional code on the implant device 110, and identifies the product information through the two-dimensional code decoding, and if the information identification fails, the identification process is ended. Successful information identification displays product information along with other patient information entered by the physician including patient device implantation date, implanted electrode information, patient complications, patient implantation clinicians, etc. The programmer 150 combines the product information with other information about the patient to generate patient implant information. Meanwhile, the program controller 150 may also transmit the patient implantation information to the server 160 through 5G or WIFI, and the server 160 stores the patient implantation information in the server 160 after receiving the patient implantation information.
The battery life of implanted devices, such as cardiac implantable pulse generators, is limited, typically 15 to 20 years. After the pulse generator is implanted into a patient, the electric quantity of a battery of the implanted equipment needs to be monitored at follow-up visit regularly, and once the battery of the implanted equipment enters a period of selective replacement, the implanted equipment needs to be replaced for the patient in time. At present, heart implantation patients regularly visit a hospital for follow-up visit, the follow-up visit period is generally 3 to 6 months, patients with good medical advice can regularly visit the hospital for follow-up visit, and the follow-up visit period of patients with poor medical advice can be unfixed. When a heart implantation patient is at home at ordinary times, how to let the patient know the battery life condition of the in-vivo implantation equipment and prompt the patient to visit a hospital regularly is very important, especially when the heart implantation equipment reaches the later stage of the battery life.
Based on this need, the combination of basic information of the implanted device and specific software of the patient terminal provides an easy way for the patient to view the battery life status of the implanted device and the patient's regular follow-up information at home. The specific software can be general software of general mobile equipment or embedded software of customized mobile equipment, and the specific software comprises a two-dimensional code decoding system for decrypting two-dimensional code information; the product information is provided by a two-dimensional code of the implanted device. The specific process is as follows: after the patient terminal obtains the product information by scanning and decoding the two-dimensional code, recent follow-up information of the patient corresponding to the product information is obtained from the server, and the recent follow-up information comprises the service life of the battery and the follow-up time.
When the system is applied, a patient opens specific software through mobile equipment, the two-dimensional code of the implanted equipment is scanned by using the specific software, the specific software acquires recent follow-up visit information (including battery life condition and follow-up visit time) of the patient corresponding to the unique serial number of the product from a server through the unique serial number of the product after decoding the product information through the two-dimensional code, and the battery life condition and the next follow-up visit time of the implanted equipment of the patient are prompted according to the recent follow-up visit information, so that the condition that the patient is forgotten to go to a hospital for follow-up visit can be effectively prevented. When a patient visits a hospital each time, a doctor actively synchronizes recent follow-up information to a server through a program controller or a program controller so as to facilitate specific software to acquire the recent follow-up information. For patients who do not synchronize recent follow-up information to the server, the specific software can perform preliminary budget estimation according to basic information carried by the product information to perform estimation prompt on the battery life of the patient (for example, the residual life can be calculated approximately according to the production date and the expected life of the product), and prompt the patient to timely arrive at the hospital for synchronizing information, so that accurate information can be provided for the patient.
In a possible implementation mode, the server also updates the life stage of the implanted device in real time, when the patient terminal, the doctor terminal and the program controller acquire the product information by scanning the two-dimensional code, the patient terminal, the doctor terminal and the program controller firstly acquire the current life stage of the new implanted device from the server, and when the current life stage is in the viewable stage, the two-dimensional code is decoded and the acquired product information is presented.
The implantation equipment can be divided into a plurality of life stages in the life cycle of the implantation equipment according to the characteristics and the purposes of products, wherein the life stages comprise a shelf life, a delivery period, an implantation period, a rejection period and the like. Different stages correspond to different user groups, and in order to ensure that the basic information security of the product is not leaked, the two-dimensional code product information provided by the system only allows the user groups at the corresponding stages of the product to access, and if the product is in the shelf life, only the user in the shelf life can access the two-dimensional code information of the product. Therefore, the server can record the life stage of each implanted device, and before the terminal identifies the product information, the terminal firstly acquires the current life stage of the implanted device from the server to determine whether to identify and present the product information to the user. The manufacturer terminal can scan the two-dimensional code to check the product information in all stages of the heart implantation equipment, the patient terminal, the doctor terminal and the program controller can only scan the two-dimensional code to check the product information in two checked stages after the implantation equipment is out of a warehouse and before the implantation equipment is scrapped, and once the implantation equipment is not in the stage, the product information can not be obtained by scanning the two-dimensional code.
The device management system provided by the embodiment is mainly applied to storage, acquisition and circulation of product information of implanted devices in the implantation industry in the field of medical instruments. The product information of the implanted equipment is stored through the two-dimensional code, and the basic product information of the implanted equipment is obtained through scanning and identifying the two-dimensional code through the specific terminal equipment, so that the product information of the implanted equipment can be more quickly, efficiently and safely circulated at each terminal in the equipment management system. Meanwhile, the two-dimension code stores the information of the implanted basic product after being encrypted, a general two-dimension code recognition system or software cannot read the basic information of the implanted equipment, and the information of the implanted equipment can be acquired only by a specific two-dimension code recognition system or software, so that the data safety and the privacy of a patient are protected to a certain extent.
The above-mentioned embodiments are intended to illustrate the technical solutions and advantages of the present invention, and it should be understood that the above-mentioned embodiments are only the most preferred embodiments of the present invention, and are not intended to limit the present invention, and any modifications, additions, equivalents, etc. made within the scope of the principles of the present invention should be included in the scope of the present invention.
