On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0047] As Figure 1 shown, an embodiment of the present invention provides a medical waste information processing method, including:

[0048] Step 11, receiving the medical waste transportation location information sent by an intelligent medical waste collection vehicle; the medical waste includes: various medical wastes collected by a plurality of medical waste collection bags, and each type of medical waste is identified by the Internet of Things tag of the medical waste collection bag to which it belongs;

[0049] Step 12, receiving the processing process information of the medical waste sent by a medical waste on-site treatment device;

[0050] Step 13: Receive the transfer record information of the medical waste sent by the processed medical waste collection and transfer device.

[0051] Step 14: Generate target tag data based on the medical waste transportation location information, processing process information, transfer record information, and block information of the target blockchain.

[0052] Step 15: Enclose the target tag data in the medical waste transportation location information, processing process information, and transfer record information respectively to obtain medical waste target data blocks.

[0053] Step 16: After encrypting the medical waste target data blocks with the node information of the first node in the target blockchain, obtain the encrypted medical waste target data blocks.

[0054] Step 17: Transmit the encrypted medical waste target data blocks to the second node in the target blockchain. Both the second node and the first node are any nodes in the target blockchain.

[0055] In this embodiment, the intelligent collection vehicle is used to send the transportation location information of the waste in real time to ensure that the transportation path of the waste is traceable; the receiving medical waste in-situ treatment device is used to record the treatment process of the waste to ensure that the treatment process is transparent and traceable; the receiving processed medical waste collection and transfer device is used to record the transfer information of the waste to ensure the safety of the waste during the transfer process; identifying the medical waste with IoT tags can ensure the traceability of the source and treatment process of each type of waste; the medical waste information processing method realizes the real-time monitoring of the entire process of medical waste from collection, transportation, treatment to transfer by receiving and real-time processing the medical waste transportation location information, processing process information, and transfer record information, ensuring the controllability of each link, being able to monitor data in real time, promptly discover abnormal situations (such as exceeding treatment parameters, deviation of transportation routes, etc.), and issue warnings to reduce risks; at the same time, through the real-time monitoring of the whole-process information, the medical waste information processing method can directly treat medical waste at the generation site, reducing the pollution risk and secondary pollution during the transportation process; through the design of target tag data and blockchain, it can ensure the traceability and transparency of the treatment process, realize the precise management and traceability of waste, and classified collection to reduce the risk of cross-contamination between different types of waste and improve the treatment safety.

[0056] In this embodiment, transmitting the encrypted target data block of the medical waste to the second node in the target blockchain includes: obtaining the hash value of the node information of the first node; sending the encrypted target data block of the medical waste and the hash value of the node information of the first node to at least one second node in the target blockchain, so that the at least one second node stores the encrypted target data block of the medical waste in the local block according to the hash value of the node information of the first node.

[0057] In this embodiment, after a new data block is created, it will be sent to other participants in the network for verification. Once other participants verify that the new block is valid, they will incorporate this new block into their own blockchain copy. Over time, the blockchain will continue to extend, and each new block will contain the hash value of the previous block, forming a chain. This process will continue until the blockchain reaches a preset length or is terminated by other mechanisms.

[0058] In this embodiment, the medical waste information processing method uses the dissemination and synchronization technology of the blockchain to synchronize this target data to multiple nodes, thereby realizing the non-forgery, non-tampering and uniqueness of the same target data, ensuring the security and transparency of the target data; by using blockchain technology to ensure the non-tamperability and traceability of data, realizing the transparent management of the whole process of medical waste treatment, real-time monitoring of each link through the Internet of Things technology, timely discovering and handling abnormal situations, reducing risks, and improving the efficiency and security of medical waste treatment through intelligent and automated technologies, reducing manual intervention.

[0059] In an optional embodiment of the present invention, step 14 may include:

[0060] Step 141, generating a random number according to the Internet of Things tag of the medical waste collection bag;

[0061] Step 142, obtaining the first data according to the random number, the medical waste transportation location information, the treatment process information, the transfer record information, the block information of the target blockchain, and the first encryption function;

[0062] Step 143, obtaining the second data according to the random number and the second encryption function;

[0063] Step 144, generating the target label data according to the first data and the second data.

[0064] In this embodiment, the process of generating a random number through the unique identifier of the Internet of Things tag ensures the uniqueness and unpredictability of the random number. Specifically, first, each Internet of Things tag of the medical waste collection bag has a unique identifier (such as a serial number), and this identifier can be obtained through a scanning or reading device; in order to ensure that the generated random number has sufficient randomness and unpredictability, the identifier can be hashed, for example, using SHA-256 to hash the identifier to obtain a hash value: since the hash value is usually long, a part of it can be intercepted as the random number seed, for example, taking the first 16 characters; the seed is input into a pseudo-random number generator to generate a random number K;

[0065] In step 142, the first data D1 is obtained through the first encryption function D1 = F1(K, A||B||C||D), where F1 is the encryption function of the first encryption algorithm, such as the Advanced Encryption Standard algorithm AES, K is the random number, A is the information of the medical waste transportation location, B is the information of the treatment process, C is the information of the medical waste transfer record, D is the block information of the target blockchain; || is the logical OR operation, and the transportation location information, treatment process information, transfer record information, and blockchain block information are subjected to a logical OR operation; using the random number K as the key, the data after the operation is encrypted through the encryption algorithm; the encrypted first data D1 is output for subsequent encapsulation and processing;

[0066] In step 143, the second data is obtained through the second encryption function D2 = F2(PK, K), where F2 is the encryption function of the second encryption algorithm; such as an asymmetric encryption algorithm, the public key of the recipient needs to be used for encryption, PK represents the public key, and the public key usually includes a modulus n and an exponent e; specifically, the random number K is converted into a byte stream, and the byte stream is encrypted using the public key, and the encrypted second data D2 is output for subsequent encapsulation and processing;

[0067] In step 144, through D3 = D1||D2, the first data and the second data are processed to obtain the target tag data D3;

[0068] In this embodiment, the medical waste information processing method ensures the security of the data through the encryption processing of the first encryption function and the second encryption function, and improves the encryption efficiency.

[0069] In an optional embodiment of the present invention, step 15 may include:

[0070] Step 151, encapsulating the target tag data in the extended field of the medical waste transportation location information to obtain the first intermediate data;

[0071] Step 152, encapsulate the target tag data in the extended field of the processing process information of the medical waste to obtain second intermediate data;

[0072] Step 153, encapsulate the target tag data in the extended field of the transfer record information of the medical waste to obtain third intermediate data;

[0073] Step 154, obtain the medical waste target data block according to the first intermediate data, the second intermediate data, and the third intermediate data.

[0074] In this embodiment, by embedding the target tag data into the extended fields of each piece of information, the integrity and traceability of the data are ensured, and at the same time, a basis is provided for the subsequent encryption and blockchain storage of the target data block; among them, in step 154, the first intermediate data, the second intermediate data, and the third intermediate data are randomly spliced according to a preset data format to obtain the medical waste target data block; the random order can be determined by a random number generator. For example, generate a random permutation [2, 1, 3], indicating that the splicing order is the second intermediate data, the first intermediate data, and the third intermediate data; or [3, 1, 2] indicating that the splicing order is the third intermediate data, the first intermediate data, and the second intermediate data, thereby splicing to obtain the medical waste target data block.

[0075] In an alternative embodiment of the present invention, step 16 may include:

[0076] Step 161, encrypt the medical waste data to be put on the chain with the node information of the first node in the target blockchain to obtain intermediate encrypted data;

[0077] Step 162, obtain the encrypted medical waste target data block according to the intermediate encrypted data and the third encryption function.

[0078] In this embodiment, in step 161, obtain the node information of the first node: the node public key; encrypt the medical waste data to be put on the chain E through Eenc = F1(E, K) to generate intermediate encrypted data Eenc, where K is a random number;

[0079] Use an encryption algorithm to encrypt the intermediate encrypted data Eenc. Specifically, encrypt the medical waste data to be put on the chain through T = F3(N1, Eenc), where F3 is an encryption function, such as the HMAC encryption algorithm, and N1 is the node information of the first node; further, generate the encrypted medical waste target data block Ei through Ei = Eenc || T, and || is a logical OR operation.

[0080] In an alternative embodiment of the present invention, the medical waste information processing method further includes:

[0081] Step 18: Statistically analyze the medical waste transportation location information, treatment process information, and transfer record information to obtain an analysis result, and store it in the target database.

[0082] In this embodiment, statistically analyzing the medical waste transportation location information, treatment process information, and transfer record information to obtain an analysis result includes:

[0083] Step 181: Statistically process the medical waste transportation location information to determine the occurrence frequency of each transportation location;

[0084] Step 182: Statistically process the medical waste treatment process information to determine the occurrence frequency of each treatment method;

[0085] Step 183: Statistically process the medical waste transfer record information to determine the occurrence frequency of each transfer destination;

[0086] Step 184: Compare and process according to the occurrence frequency of each transportation location, the occurrence frequency of each treatment method, the occurrence frequency of each transfer destination, and the preset warning parameters to obtain an analysis result.

[0087] In this embodiment, by statistically analyzing the frequency of the medical waste transportation location information, treatment process information, and transfer record information, it is possible to effectively know the treatment locations, methods, and processes of most medical waste, so as to facilitate strengthening management of the places with high occurrence frequencies, thereby preventing omissions. At the same time, through the setting of preset warning parameters, further reminders are given to the parameters with high occurrence frequencies. For example, when the occurrence frequency of a certain transportation location is greater than the preset warning parameter, the analysis result is output as a warning prompt result, indicating that the current place needs to be strengthened in management or there are problems; thus facilitating supervision. For example, when the occurrence frequency of a certain transportation location is greater than the set warning parameter, it proves that there is a large amount of medical waste here. Further visits can be made based on this prompt information to determine the safety of medical waste treatment here, and at the same time, the source of medical waste here can be monitored in real time.

[0088] In another analysis and processing, the traceability feasibility of the medical waste transportation location information, treatment process information, and transfer record information can be analyzed through the following function F to obtain the traceability feasibility analysis result of the medical waste;

[0089]

[0090] where c i represents the cost of the i-th transportation; p i represents the cost of the i-th treatment; t i represents the time of the i-th transportation; hi Indicates the time of the i-th processing; s i represents the compliance score of the i-th treatment; w1, w2 and w3 are weight coefficients; i is the index variable; n is the total number of times, which represents the total number of operations of transportation and treatment during the treatment of medical waste. If the value of F is smaller, it means that the traceability feasibility is better.

[0091] The medical waste information processing method described in the present invention realizes real-time monitoring and automated processing of medical waste through the Internet of Things technology, greatly improving processing efficiency, reducing manual operations, and reducing processing costs; utilizing the immutability and traceability of blockchain technology to realize transparent supervision of the entire process of medical waste treatment, effectively preventing illegal dumping and secondary pollution of medical waste; through the identification function of intelligent medical waste collection vehicles, accurate collection and transportation of medical waste can be achieved, resource allocation can be optimized, transportation efficiency can be improved, a unified medical waste treatment information platform can be established, information sharing between medical institutions, treatment units and regulatory departments can be realized, and collaborative efficiency can be improved.
