Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.

Fig. 1 is a flowchart one of a first-aid method based on a blockchain network according to an exemplary embodiment of the present application, and as shown in fig. 1, mainly includes the following steps:

in step 101, pre-hospital emergency information of a patient uploaded by an emergency party is received, the pre-hospital emergency information is consensus through a consensus node in the blockchain network, and after the consensus of the pre-hospital emergency information is completed, the pre-hospital emergency information is stored in a block of the blockchain network; wherein, the pre-hospital emergency information includes: information generated by the emergency party during pre-hospital emergency treatment of the patient;

in step 102, a query request for pre-hospital emergency information initiated by a medical party is received, the pre-hospital emergency information corresponding to the patient is obtained from the blockchain network according to the query request, and the pre-hospital emergency information is output to the medical party;

In step 103, receiving the post-hospital diagnosis information uploaded by the medical party, performing consensus on the post-hospital diagnosis information through a consensus node in the blockchain network, and after the consensus on the post-hospital diagnosis information is completed, storing the post-hospital diagnosis information into a block of the blockchain network; wherein the post-hospital diagnostic information includes: the emergency party carries out the information generated in the process of post-hospital diagnosis on the patient according to the pre-hospital emergency information;

in step 104, the block hash value of the block where the pre-hospital emergency information is located and the block hash value of the block where the post-hospital diagnostic information is located are associated by the association relationship intelligent contract in the blockchain network.

Here, the emergency party may refer to an emergency center, for example, may be an emergency center worker or an emergency center server; a medical party may refer to a hospital, for example, a hospital staff or a hospital server. Blockchains may refer to the storage structure of encrypted, chained transactions formed by blocks. For example, the header of each chunk may include both the hash values of all transactions in the chunk and the hash values of all transactions in the previous chunk, thereby enabling tamper-and anti-counterfeiting of transactions in the chunk based on the hash values; the newly generated transactions, after being filled into the block and passing through the consensus of the nodes in the blockchain network, are appended to the tail of the blockchain to form a chain growth. A blockchain network may refer to a collection of nodes that incorporate new blocks into the blockchain in a consensus manner.

In each of the embodiments of the present application, an emergency treatment party is taken as an emergency treatment center, and a medical party is taken as a hospital as an example.

Fig. 2 is a schematic diagram illustrating a block chain network according to an exemplary embodiment of the present application. As shown in fig. 2, in the process that the ambulance receives a patient and starts to a hospital, a worker on the ambulance performs pre-hospital emergency on the patient, and uploads pre-hospital emergency information generated in the process of performing pre-hospital emergency to the emergency center server 200, and then the pre-hospital emergency information is uploaded to the blockchain network 100 by the emergency center server. In some embodiments, a staff member on the ambulance may conduct a remote collaborative consultation with the hospital when the patient is first-aid. Here, the pre-hospital emergency information may include: patient sign information, patient complaint information, records of emergency measures taken, consultation comments of remote collaborative consultation in hospitals, uploading personnel information and the like. In some embodiments, when a worker in the emergency center receives an emergency call, information such as time of receiving the emergency call and call records with a dialer can be recorded and uploaded to the emergency center server, and then the information such as time of receiving the emergency call and call records with the dialer can be uploaded to the blockchain network as pre-hospital emergency information by the emergency center server.

After receiving the pre-hospital emergency information uploaded by the emergency party, the blockchain network needs to carry out consensus on the received pre-hospital emergency information through a consensus node in the blockchain network, and after completing the consensus on the pre-hospital emergency information, the received pre-hospital emergency information is stored in a new block of the blockchain. Here, the consensus refers to: a process in a blockchain network for agreeing on transactions in blocks among a plurality of nodes involved, the agreed blocks to be appended to the tail of the blockchain, mechanisms for implementing the agreements including a PoW (Proof of Work) mechanism, a PoS (Proof of equity) mechanism, a DPoS (shared Proof of-status) mechanism, a PoET (Proof of Elapsed Time, elapsed amount of time) mechanism, and the like.

After the patient arrives at the hospital, in the case that the hospital has the patient's identity information, the hospital staff can enter the patient's identity information in the search box of the blockchain browser to query the patient for pre-hospital emergency information. That is, a staff member of the hospital may initiate a query request for pre-hospital emergency information for the patient based on the identity information of the patient. In some embodiments, where a hospital staff member has a block hash value of the block in which the pre-hospital emergency information of the patient is located or a billing transaction address of the pre-hospital emergency information, the hospital staff member may enter the block hash value of the block in which the pre-hospital emergency information of the patient is located or the billing transaction address of the pre-hospital emergency information in a search box of a blockchain browser to query the pre-hospital emergency information of the patient. That is, a hospital staff may initiate a query request for pre-hospital emergency information for a patient based on the block hash value of the block in which the pre-hospital emergency information of the patient is located or the billing transaction address of the pre-hospital emergency information. The blockchain network may obtain the pre-hospital emergency information of the patient from the blockchain network after receiving the query request for the pre-hospital emergency information of the patient, and then output the pre-hospital emergency information to a staff member of the hospital, for example, by way of a file, or directly display the obtained pre-hospital emergency information on an interface of a blockchain browser.

As shown in fig. 2, a staff member of a hospital, such as a doctor, can refer to pre-hospital emergency information of a patient after obtaining the pre-hospital emergency information of the patient and perform post-hospital diagnosis on the patient, so that the doctor can perform the post-hospital diagnosis directly according to the pre-hospital emergency information without taking a new measure to obtain information already contained in the pre-hospital emergency information, thereby saving the time of the post-hospital diagnosis. After diagnosing the patient, the hospital staff may upload post-hospital diagnosis information generated in the process of performing post-hospital diagnosis to the hospital server 300, and then upload the post-hospital diagnosis information to the blockchain network 100 by the hospital server. Here, the medical party may include a hospital server, and the post-hospital diagnosis information may include: the detailed diagnosis process (the diagnosis process can be recorded by text or by pictures or videos), medical consumables, medicines and cost generated in the diagnosis process, return visit after discharge, uploading personnel information and other information. After receiving the post-hospital diagnosis information uploaded by the hospital server, the blockchain network needs to carry out consensus on the received post-hospital diagnosis information through a consensus node in the blockchain network, and after completing consensus on the post-hospital diagnosis information, the received post-hospital diagnosis information can be stored in a new block of the blockchain.

In some embodiments, both pre-hospital emergency information and post-hospital diagnostic information may be stored in blocks of emergency information side chains in a blockchain network. In other embodiments, the blockchain network may include pre-hospital emergency information side chains and post-hospital diagnostic information side chains, in which case the pre-hospital emergency information may be stored in blocks of pre-hospital emergency information side chains in the blockchain network and the post-hospital diagnostic information may be stored in blocks of post-hospital diagnostic information side chains in the blockchain network.

The intelligent contract side chain of the blockchain network can contain intelligent contracts with various functions, for example, an association relationship intelligent contract can associate the block hash value of the block where the information with the association relationship is located; the triage intelligent contract can obtain triage results according to pre-hospital first-aid information; the intelligent contract for claim settlement can judge whether the patient meets the condition for claim settlement according to pre-hospital first-aid information, post-hospital diagnosis information and insurance contract in the insurance business side chain, and the claim settlement is carried out under the condition that the condition for claim settlement is met.

Fig. 3 is a schematic diagram illustrating the operation of a smart contract according to an exemplary embodiment of the present application. As shown in fig. 3, the intelligent contract may correlate information in blocks of different side chains and store the correlation relationship in a block of the side chain of the intelligent contract, or the intelligent contract may complete a preset service according to information of blocks of different side chains and then store information generated by performing the preset service in a block of the side chain of the intelligent contract. For example, the smart contract 1 in fig. 3 may be an associative smart contract, and the smart contract 1 may associate the block hash value of the block 1 of the pre-hospital emergency information side chain with the block hash value of the block 1 of the post-hospital diagnostic information side chain to achieve the association of the information in the block 1 of the pre-hospital emergency information side chain with the information in the block 1 of the post-hospital diagnostic information side chain, and save the associative relationship to the block 1 of the smart contract side chain. Also for example, the intelligent contract 2 in fig. 3 may be a diagnosis-by-diagnosis intelligent contract, and the intelligent contract 2 may obtain diagnosis results according to the information in the block 2 of the side chain of the pre-hospital emergency information and the information in the block 2 of the side chain of the post-hospital diagnosis information, and store the diagnosis results in the block 2 of the side chain of the intelligent contract.

Under the condition that pre-hospital emergency information of a patient is stored in a blockchain network and post-hospital diagnosis information of the patient is stored in the blockchain network, an association intelligent contract in the blockchain network is automatically triggered, and the block hash value of the block where the pre-hospital emergency information corresponding to the same patient is located and the block hash value of the block where the post-hospital diagnosis information is located are associated through the association intelligent contract, so that the association of the pre-hospital emergency information and the post-hospital emergency information of the same patient is realized. After the pre-hospital emergency information and the post-hospital emergency information are associated, the pre-hospital emergency information and the post-hospital diagnostic information of a patient may be queried simultaneously when a user of the blockchain network (including the patient, a staff member of an institution participating in the blockchain network, or other user) queries the pre-hospital emergency information or the post-hospital diagnostic information of the patient through the blockchain browser.

In the embodiment of the application, the pre-hospital emergency information uploaded by the emergency party can be received, then the pre-hospital emergency information is stored in a block of the blockchain network, and when the medical party initiates a query request for the pre-hospital emergency information, the pre-hospital emergency information can be obtained from the blockchain network and output to the medical party so as to assist the medical party in performing post-hospital diagnosis on the patient according to the pre-hospital emergency information. After the medical side performs post-hospital diagnosis on the patient according to the pre-hospital emergency information, the post-hospital diagnosis information uploaded by the medical side can be received and stored in a block of the blockchain network. Thus, information sharing in the emergency treatment process can be realized, namely, pre-hospital emergency information can be inquired when a medical party performs post-hospital diagnosis, so that the post-hospital diagnosis can be completed by referring to the pre-hospital emergency information. Meanwhile, the blockchain network has the characteristics of high reliability, high safety and strong traceability, so that pre-hospital first-aid information and post-hospital diagnosis information are stored in the blocks of the blockchain, and the safety of the information can be ensured.

Prior to receiving pre-hospital emergency information of a patient uploaded by an emergency party, the blockchain network-based emergency method provided by the embodiments of the present application may further include: the process of building a blockchain network is as follows:

constructing a blockchain network on a cloud server, and initializing a preselected node, an creation block of a main chain and an creation block of a side chain; the content in the created blocks of the main chain can be the configuration information of the blocks and the main chain, and mainly can comprise: hash algorithm (e.g., sha256 algorithm), consensus algorithm (e.g., bayesian fault tolerance algorithm), node type (e.g., may include voting nodes, billing nodes and intelligent contract nodes), node rights (rights of heterogeneous nodes when participating in backbone and different side-chain traffic), organization policy of newly joined organization members, and upper limit of backbone block size (e.g., 5M), etc.; the content of the creation block of the side chain can be the configuration information of the block and the side chain, and mainly can comprise: the service function identification of the side chain, a hash algorithm (e.g., sha256 algorithm), a consensus algorithm (e.g., a bayer fault-tolerant algorithm), a side chain block size upper limit (e.g., 10M), and the like.

After the blockchain network is created, the creator of the blockchain network may send an invitation to the mail inviting the organization to join the blockchain network, the organization filling in registration information in the blockchain registration platform link within the mail. If the invitee is an entity participating in blockchain collaborative governance, then after a target pass rate (e.g., 2/3 of the voting nodes vote through), the entity federation is completed and the pre-selected nodes are assigned to the invitee. If the preselected node has been assigned to run out at this point, the invitee needs to create a voting node by itself, joining the blockchain backbone.

If the invitee does not participate in the cooperative management of the blockchain and only participates in some links of the blockchain service, the invitee needs to join the blockchain from the node, the preselected node votes to determine whether the node of the invitee can join the blockchain, after the node joins, corresponding authority can be allocated to the node according to the node type and the links in which the invitee participates, the organization information and the node information which the invitee belongs to are recorded on the main chain, and if the organization information or the information which the organization information belongs to changes, a new block with higher block height can be generated to record updated information. In some embodiments, the invited organization may include an emergency center, a hospital, and an insurance company, and the creator of the blockchain network may be any of the emergency center, the hospital, and the insurance company, and may be a regulatory agency or a service provider.

in step 401, sending an invitation mail to a target institution to be invited; the invitation mail comprises links of a blockchain registration platform;

in step 402, the target institution fills in registration information in the links of the blockchain registration platform in the mail;

in step 403, after receiving the registration information of the target mechanism, the blockchain network votes whether to allow the target mechanism to join the blockchain network through the voting node;

in step 404, it is determined whether the voting nodes agree.

In step 405, in the case that the voting node achieves consensus, corresponding rights, public key, private key and node are allocated to the target organization, and registration information of the target organization is saved to the blockchain network.

Here, if the preselected node that votes does not agree, the target organization is not allowed to join the blockchain network.

In some embodiments, a blockchain network-based first aid method provided herein may include:

In this way, mechanisms that can join the blockchain network can be screened out by voting of consensus nodes and allowed to join the blockchain network.

For example, personnel on the ambulance may upload pre-hospital emergency information generated during pre-hospital emergency of the patient to the emergency center server, and then upload the pre-hospital emergency information to the blockchain network for storage by the emergency center server; the staff of the hospital can upload the diagnosis information after hospital that is produced in the process of diagnosing after hospital on the patient to the hospital server, then upload the diagnosis information after hospital to the blockchain network to save by the hospital server, the hospital server can also upload the electronic medical record of all patients that keep in the server to the blockchain network directly to save (the data of the electronic medical record can be any form of data, such as character string, boolean value, digital etc., and the data of the electronic medical record uploaded by the server is all processed by the intelligent contract in the blockchain network after uploading to the blockchain network, the uploaded data is converted into the billing and uplink after presetting the format); the staff of the insurance company can upload the insurance business information of the patient to the insurance company, and then the insurance business information is uploaded to the blockchain network by the server of the insurance company for storage.

As shown in fig. 5, the blockchain network in the embodiment of the present application may be formed by the first aid party, the medical party and the insurer together, and the blockchain network in the embodiment of the present application may include one main chain and five side chains, where the five side chains may include: first aid information side chains, member management side chains, insurance business side chains, electronic medical record side chains, and intelligent contract side chains, and related nodes can include pre-selection nodes, voting nodes, accounting nodes, and intelligent contract nodes. The roles of the main chain, side chains and related nodes in a blockchain network are described below.

1) A main chain: the main chain business comprises an organization registration module, a node allocation module and a permission control module. The mechanism registration module is used for filling in mechanism information of the mechanism participating in the emergency procedure and registering. The node assignment module is used to assign preselected nodes of the blockchain to registered institutions, one institution may be assigned to one or more nodes bi-directionally anchored with different side chains, depending on the role it plays in the emergency procedure and the importance of participation. The authority control module is used for configuring the authority of inquiring, accounting and calling intelligent contracts for the nodes allocated to the registered institutions.

2) Side chain of emergency information: the side chain of the emergency information is used for storing relevant emergency information records (including the contents of communication records with an alarm, patient complaints, patient signs, remote consultation conclusions, diagnosis results, emergency measures, emergency consumables, required medicines, discharge and return visit records and the like from the pre-admission to the post-admission), and each emergency information of each patient is stored in one block. The first aid information may include pre-hospital first aid information, triage results, and post-hospital diagnostic information, among others.

3) Side chain management of members: the method is used for registering personal information filled in by staff and patients of different institutions and storing registered user information. And the permissions such as inquiry, information maintenance and the like of registered personnel are allocated. Each member information is stored in a block.

4) Insurance business side chain: record insurance business record information (including information of insurance contract, time of applying insurance claim, reason, investigation result, claim result, etc.) of all patients. Each insurance business record information is stored in a block.

5) Electronic medical record side chain: recording the electronic medical record information of all registered patients, wherein the electronic medical record information of each patient is stored in one block.

6) Intelligent contract side chain: the intelligent contract system is used for storing intelligent contract examples and data which need to finish business logic in a cross-chain cooperative mode, and the data required by each intelligent contract when being called or the data of the called intelligent contract examples are stored in a block.

7) Preselection node: since the Bayesian fault-tolerant consensus algorithm requires at least 4 voting nodes, i.e. at least 2/3 of the preselected nodes and voting node acknowledgements are required when a new organization is added, more than 4 voting nodes need to be established at the time of initialization of the blockchain, which are referred to as preselected nodes.

8) Voting node: the mechanism management service of the block chain main chain is participated, each node votes to decide the joining and exiting of the mechanism, and the voting flow follows the Bayesian fault-tolerant consensus algorithm.

9) Accounting node: accounting nodes each have a complete data ledger of all chains that they participate in accounting for transactions involving one or more chains.

10 Intelligent contract node): when the business triggers the intelligent contract, the intelligent contract node invokes the data of the related chain and completes the corresponding business logic processing, and the invoked intelligent contract instance data is stored on one block of the intelligent contract side chain.

In some embodiments, the side-chain of emergency information may include a pre-hospital emergency information side-chain and a post-hospital diagnostic information side-chain, the pre-hospital emergency information being stored in a block of the pre-hospital emergency information side-chain, the post-hospital diagnostic information being stored in the post-hospital diagnostic information side-chain.

In the embodiment of the application, different service data are respectively stored in the side chains of the blockchain, so that data isolation among the chains is realized, and the service progress among other side chains is not influenced under the assumption that part of nodes on one side chain are attacked or failed.

In some embodiments, the receiving pre-hospital emergency information of the patient uploaded by the emergency party, the pre-hospital emergency information being consensus by a consensus node in the blockchain network may include:

the receiving the post-hospital diagnosis information uploaded by the medical party, and consensus the post-hospital diagnosis information through a consensus node in the blockchain network may include:

In some embodiments, the first pre-selected node and the second pre-set node may each comprise a node that participates in emergency information side-chain billing. The first preset node may be the same as the second preset node or may be different from the second preset node.

In some embodiments, when a first aid party (e.g., a worker in a first aid center) uploads pre-hospital emergency information to a first aid center server, the pre-hospital emergency information may be uploaded to the first aid center server via a network interface (e.g., REST API, REpresentational State Transfe API, a network interface representing a layer state transition style), after the first aid center server receives the pre-hospital emergency information uploaded by the worker, the pre-hospital emergency information may be processed into data in a preset format, encrypted with a public key of a first preset node, signed with a private key of the first aid center, time stamped, and uploaded to a blockchain network.

In some embodiments, the blockchain network may decrypt the pre-hospital emergency information with the private key of the first preset node through the first preset node after receiving the pre-hospital emergency information in a preset format encrypted with the public key of the first preset node and signed with the private key of the emergency center, verify the pre-hospital emergency information with the public key of the emergency center, and then forward the pre-hospital emergency information after decryption and verification to a consensus node in the blockchain network for consensus, and save the pre-hospital emergency information to a block of the blockchain network after the consensus is completed.

In some embodiments, the emergency center server may upload pre-hospital emergency information into the blockchain network in a manner that issues a billing request to the first preset node (the billing request includes pre-hospital emergency information in a preset format that is encrypted with the public key of the first preset node and signed with the private key of the emergency center).

When a medical side (such as a staff member of a hospital) uploads the post-hospital diagnosis information to a hospital server through a network interface (for example, REST API), the hospital server receives the post-hospital diagnosis information uploaded by the staff member, processes the post-hospital diagnosis information into data in a preset format, encrypts the data with a public key of a second preset node, signs with a private key of the hospital, and uploads the data to a blockchain network after time stamping. After receiving the post-hospital diagnosis information in the preset format signed by the private key of the hospital through the second preset node, the blockchain network decrypts the post-hospital diagnosis information through the second preset node by using the private key of the second preset node, verifies the post-hospital diagnosis information through the public key of the medical party, and then forwards the post-hospital diagnosis information after decryption and verification to a consensus node in the blockchain network for consensus, and after the consensus is completed, the post-hospital diagnosis information is stored in a block of the blockchain network.

In some embodiments, the server of the medical party may upload the post-hospital diagnostic information into the blockchain network in a manner that issues a billing request to the second preset node (the billing request includes the post-hospital diagnostic information in a preset format encrypted with the public key of the second preset node, signed with the private key of the hospital). Thus, the safety of the patient information can be increased, and the risk of leakage of the patient information can be reduced.

In some embodiments, the first-aid method based on the blockchain network provided in the embodiments of the present application may further include:

It will be appreciated that when the identity information of the patient is not known, pre-hospital emergency information for the patient is not available from the blockchain network.

Here, after the pre-hospital emergency information is saved in the block of the blockchain network, the block identifier of the block in which the pre-hospital emergency information is located may be encoded and written into the identifier carrier. The identification carrier may comprise: an information identification code (e.g., an information two-dimensional code) or an information identification chip (e.g., an RFID chip, radio Frequency Identification, radio frequency identification chip). The identification carrier can be carried by a patient, after the patient arrives at a hospital, a staff of the hospital can open the blockchain browser to scan the information identification code or read the information identification chip through the chip reader so as to acquire the blockname of the block where the pre-hospital first-aid information of the patient is located, and then acquire the pre-hospital first-aid information of the patient according to the blockname of the block where the pre-hospital first-aid information of the patient is located.

Like this, when can't learn patient's identity, can regard as patient's interim identity with the information identification code or the information identification chip that patient carried for discern patient's identity in whole first aid process, still be used for transmitting patient's pre-hospital first aid information (the block sign of the first aid information place block of patient) to the staff who carries out follow-up procedure, the staff can acquire the block sign from the sign carrier convenient reliably.

In some embodiments, the receiving the query request for the pre-hospital emergency information initiated by the medical party, and obtaining the pre-hospital emergency information corresponding to the patient from the blockchain network according to the query request may include:

Here, the block identification may include a block hash value of the block in which the pre-hospital emergency information is located and a billing transaction address of the pre-hospital emergency information.

Thus, when the identity of the patient cannot be known, a medical party (such as a staff in a hospital) can initiate a query request to the identification carrier by scanning the information identification code through the blockchain browser or reading the information identification chip through the chip reader so as to read the block identification in the identification carrier. Furthermore, the pre-hospital first-aid information of the patient can be obtained from the block corresponding to the block identifier in the block chain network according to the information identifier code or the block identifier of the block where the first-aid information in the information identification chip is located.

In some embodiments, after the block identifier in the identifier carrier is read, the block identifier may be compared with the block identifiers of all the blocks in the blockchain network, and then, according to the comparison result, the block corresponding to the block identifier is determined, so as to obtain pre-hospital first-aid information of the patient from the block corresponding to the block identifier. For example, in some embodiments, a block in the blockchain network may be determined to be a block corresponding to a block identifier read from the identifier carrier when the block identifier of the block in the blockchain network is identical to or greater than a predetermined similarity to the block identifier read from the identifier carrier.

It can be understood that the intelligent contract side chain in the blockchain network can store the diagnosis-dividing intelligent contract, and the diagnosis-dividing intelligent contract can automatically divide the diagnosis of the patient according to the pre-hospital first-aid information of the patient to obtain the diagnosis-dividing result. Here, the triage result may include a severity level of the patient's condition and a graded basis for hit of the level. Here, the triage smart contract may include an NLP (Natural Language Processing ) algorithm.

The staff (such as doctor) of the hospital can initiate the triage request on the blockchain browser, after the staff of the hospital scans the information identification code through the blockchain browser or reads the information identification chip through the chip reader, the functional keys of triage can be displayed in the blockchain browser, and the staff of the hospital can initiate the triage request by clicking the functional keys of triage. After receiving a diagnosis separating request initiated by a staff of a hospital, the blockchain network can automatically trigger an intelligent contract node to call a diagnosis separating intelligent contract, obtain a diagnosis separating result through the diagnosis separating intelligent contract and pre-hospital first aid information of a patient, and then output the diagnosis separating result in a text display mode, a file mode or a voice playing mode on an interface of a blockchain browser.

In some embodiments, after the triage result corresponding to the pre-hospital emergency information is obtained according to the triage smart contract and the pre-hospital emergency information, the triage result may be saved in a smart contract side chain.

In some embodiments, after learning the triage result of the patient, a staff member of the hospital may assign a doctor corresponding to the triage result to the patient for post-hospital diagnosis of the patient. In some embodiments, the physician may perform a post-hospital diagnosis of the patient based on the triage results.

Therefore, before the doctor diagnoses the patient, the doctor can automatically triage the patient according to the pre-hospital emergency information of the patient in advance, and then the triage result assists the doctor in performing post-hospital diagnosis on the patient, so that the time for the doctor to perform post-hospital diagnosis on the patient can be saved.

In some embodiments, the patient's identification may include the patient's identification number, a cell phone number, a unique user ID generated by the patient at registration, or a two-dimensional code.

It can be appreciated that after knowing the identity of the patient, the identity information, the electronic medical record, and the insurance contract corresponding to the identity can be obtained from the blockchain network according to the identity of the patient. In some embodiments, after the block hash value of the block where the identity information corresponding to the patient is located, the block hash value of the block where the pre-hospital emergency information is located, the block hash value of the block where the post-hospital diagnosis information is located, the block hash value of the block where the electronic medical record is located, and the block hash value of the block where the insurance contract is located are associated by the association intelligent contract in the blockchain network, the association of the block hash values of the blocks where the various information is located may be written into the side chain of the intelligent contract for storage.

Here, then, association of all information corresponding to the patient in the blockchain network may be achieved. When a user of the blockchain network (including a patient, a staff member of a mechanism participating in the blockchain network or other users) queries a certain type of information of a certain patient through the blockchain browser, all information related to the patient is output, so that the user can query the information more conveniently.

Here, the claim initiator may be the patient or the family member of the patient, or may be a worker of the insurance company.

It can be appreciated that the intelligent contracts for claims can be stored in the intelligent contracts side chains in the blockchain network, and the intelligent contracts for claims can analyze various information of the patient in the blockchain network to judge whether the patient meets the claims-settling conditions, and if the patient is determined to meet the claims-settling conditions, the claims are settled for the patient according to the claims-settling mode recorded in the insurance contract.

The claim settlement party can initiate a claim settlement request on the blockchain browser, for example, by clicking a function button of the claim settlement displayed on a display interface of the blockchain browser. After receiving the claim settlement request initiated by the claim settlement party, the blockchain network can automatically trigger the intelligent contract node to call the claim settlement intelligent contract, analyze various information of the patient in the blockchain network through the claim settlement intelligent contract to judge whether the patient meets the claim settlement condition, and perform claim settlement on the patient according to the claim settlement mode recorded in the insurance contract under the condition that the patient meets the claim settlement condition.

In some embodiments, after the claims are resolved in the manner of the claims in the insurance contract, information generated during the claims are saved to the intelligent contract side chain.

Therefore, the claim settlement is automatically carried out through the claim settlement intelligent contract in the blockchain network, and compared with the method that the personnel of the insurance company acquire the information of the patient to carry out the claim settlement, the risk of information leakage of the patient can be reduced, and the privacy of the patient is protected.

In some embodiments, the preset algorithm may be an NLP (Natural Language Processing ) algorithm. The event extraction is performed on the insurance contract through a preset algorithm, and may specifically be performed on the claim settlement terms in the insurance contract. After the event is extracted from the insurance contract through the preset algorithm, a prediction library can be formed according to the event extracted from the insurance contract, then the event extracted from the pre-hospital emergency information, the post-hospital diagnosis information and the electronic medical record of the patient is matched with the event in the prediction library, and the patient is determined to meet the claims condition under the condition that the event extracted from the pre-hospital emergency information, the post-hospital diagnosis information and the electronic medical record of the patient is matched with the event in the prediction library.

Here, by matching events extracted from pre-hospital emergency information, post-hospital diagnostic information, and electronic medical records with events extracted from insurance contracts, it can be relatively accurately determined whether the patient satisfies claims. Meanwhile, the risk of leakage of patient information can be reduced, and the workload of staff of an insurance company can be reduced.

Here, the inquirer may include a patient, a staff member of an organization participating in the blockchain network, or other users of the blockchain network. The target object may include information of the patient, a staff member of an organization participating in the blockchain network, or other users of the blockchain network, as well as the patient, the staff member of an organization participating in the blockchain network, or other users of the blockchain network. The target object of the query by the query party can be the query party itself or other people besides the query party.

The inquirer can acquire the information of the target object by inputting the identity of the target object or the block identity of the target object in the blockchain browser.

Here, under the condition that the inquirer has the authority to inquire the pre-hospital emergency information and/or the post-hospital emergency information of the target object, the pre-hospital emergency information and/or the post-hospital emergency information of the target object can be acquired, and the pre-hospital emergency information and/or the post-hospital emergency information of the target object can be output to the inquirer, so that the risk of information leakage of the target object can be reduced.

It can be understood that when the querying party wants to query the electronic medical record or insurance contract of the target object, it is also required to verify whether the querying party has the authority to query the electronic medical record or insurance contract of the target object, and under the condition that the querying party has the authority to query the electronic medical record or insurance contract of the target object, the electronic medical record or insurance contract of the target object is obtained, and the electronic medical record or insurance contract of the target object is output to the querying party.

In some embodiments, the user information stored in the blockchain network includes authority information of the user, for example, authority information of the querying party is included in the user information of the querying party. The inquirer may have the right to view all or some kind of information of some users (e.g., some type of patient), e.g., the inquirer has the right to inquire pre-hospital emergency information of some patients. It should be noted that, the query request for the target object initiated by the querying party may carry the identity of the querying party, the identity of the target object and the type of target information to be queried by the query request. After receiving a query request for a target object initiated by a query party, the identity information of the query party can be acquired from the blockchain network according to the identity identification of the query party carried in the query request, and then the authority information of the query party is acquired from the identity information of the query party. Then judging whether authority information of the inquiring party contains authority capable of checking the target information type of the target object; when the authority information of the inquirer contains the authority capable of viewing the target information type of the target object, the inquirer has the authority capable of viewing the target type information of the target object.

As shown in fig. 6, a method of a first-aid method based on a blockchain network provided in an embodiment of the present application may include the following steps:

in step 601, an emergency party uploads pre-hospital emergency information of a patient to a blockchain network.

In step 602, it is determined whether the identity of the patient can be confirmed.

Here, whether the patient carries an identity mark such as a certificate or a carrier capable of indicating an identity may be determined by the first aid party, and the identity of the patient may be confirmed according to the certificate or the carrier capable of indicating an identity. For example, the credentials capable of indicating the identity of the patient may include an identity card, and the carrier capable of indicating the identity of the patient may include a two-dimensional code corresponding to the identity information generated after the patient is registered in the blockchain browser.

In step 603, under the condition that the identity of the patient can be confirmed, the block hash value of the block where the electronic medical record of the patient is located is obtained through the identity of the patient, the block hash value of the block where the electronic medical record is located and the block hash value of the block where the pre-hospital emergency information is located are encoded, and the identification carrier is written.

For example, the emergency department may input the identification number of the patient in the blockchain browser, or scan the two-dimensional code of the patient through the blockchain browser to obtain the identity information of the patient, the electronic medical record associated with the identity information, and the blockhash value of the block in which the electronic medical record is located. Then, the block hash value of the block where the electronic medical record is located and the block hash value of the block where the pre-hospital emergency information is located are encoded, and the identification carrier is written.

In step 604, in the event that the identity of the patient cannot be confirmed, the block hash value of the block in which the pre-hospital emergency information of the patient is located is encoded and written into the identification carrier.

In step 605, the medical party reads the tile identifier from the identifier carrier.

In step 606, it is determined whether the medical party has query rights.

Here, it may be specifically determined whether the medical side has authority to inquire about pre-hospital emergency information of the patient. After the medical side reads the block identifier from the identifier carrier, a query request for pre-hospital first-aid information stored in the block corresponding to the block identifier is initiated; the query request may carry the identity of the medical party, the identity of the patient (the patient corresponding to the block identifier) to which the pre-hospital first-aid information stored in the block corresponding to the block identifier belongs, and the information type of the information stored in the block corresponding to the block identifier, that is, the pre-hospital first-aid information. After receiving a query request of information stored in a block corresponding to the block identifier initiated by a medical party, the identity information of the medical party can be acquired from the blockchain network according to the identity identifier of the medical party carried in the query request, and then the authority information of the medical party is acquired from the identity information of the medical party. Then judging whether the authority information of the medical party contains the authority capable of checking pre-hospital first-aid information of the patient corresponding to the block mark; when the authority information of the inquiring party comprises the authority capable of checking the pre-hospital emergency information of the patient corresponding to the block identification, the medical party has the authority for inquiring the pre-hospital emergency information of the patient.

In step 607, if the medical party has the authority to query the pre-hospital emergency information of the patient, the pre-hospital emergency information of the patient is obtained according to the block identification and is output to the medical party.

Here, if the medical party does not have the authority to query the pre-hospital emergency information of the patient, the pre-hospital emergency information of the patient is not acquired according to the block identification.

It should be noted that the medical staff may be a doctor or other staff member of the hospital.

As shown in fig. 7, a method of a first-aid method based on a blockchain network provided in an embodiment of the present application may include the following steps:

in step 701, a blockchain network is built on a cloud server, initializing preselected nodes, an creation block of a backbone, and an creation block of a side chain.

Initializing the creation block of the backbone may include initializing the contents of a hash algorithm, a consensus algorithm, a node type, a node authority, an organization policy of a newly added organization member, an upper limit of the size of the backbone block, and the like in the creation block of the backbone. The generation module for initializing the side chains can comprise the steps of initializing the service function identification, the hash algorithm, the consensus algorithm, the upper limit of the side chain block size and the like of each side chain.

In step 702, an emergency center, a hospital, and an insurance company are invited to join a blockchain network and rights, public keys, private keys, and nodes are assigned to the emergency center, the hospital, and the insurance company, respectively.

Here, the links of the blockchain registration platform may be included in the invitation mail by sending the invitation mail to the emergency center, the hospital, and the insurance company. The emergency center, hospital and insurance company then register by filling in registration information in the links of the blockchain registration platform in the mail. After the blockchain network receives the registration information of the emergency center, the hospital and the insurance company, whether the emergency center, the hospital and the insurance company are allowed to join the blockchain network is voted through the voting node, corresponding authority, public key, private key and node are distributed to the target institution under the condition that the voting node achieves consensus, and the registration information of the target institution is stored in the blockchain network.

In step 703, the patient and emergency center, hospital and insurance company personnel are registered with the blockchain registration platform.

After the staff of the patient and the emergency center, the hospital and the insurance company are registered on the blockchain registration platform, corresponding authorities can be allocated to the staff of the patient and the emergency center, the hospital and the insurance company, and unique user IDs and two-dimensional codes corresponding to the identity information are generated.

In step 704, identity information of registered users and business information of hospitals and insurance companies are saved into the blockchain network.

Here, the identity information of the user may be saved to a member management side chain in the blockchain network, the electronic medical record information of the patient in the hospital may be saved to an electronic medical record side chain in the blockchain network, and the insurance business information of the insurance company, such as an insurance contract, may be saved to an insurance business side chain of the blockchain network. Registered users may include registered patients, registered emergency centers, staff of hospitals and insurance companies. The business information may include electronic medical record information of the patient, insurance contracts, and the like. Thus, when certain service information needs to be acquired in the subsequent service, the service information can be directly acquired from the blockchain network.

In step 705, the emergency party performs pre-hospital emergency on the patient, uploads pre-hospital emergency information to the blockchain network, encodes the blockhash of the block where the pre-hospital emergency information is located, and writes the coded blockhash into the identification carrier.

The identification carrier may comprise: an information identification code (e.g., an information two-dimensional code) or an information identification chip (e.g., an RFID chip). The identification carrier may be carried by the patient, for example, after the patient arrives at the hospital, a staff (medical side) of the hospital may open the blockchain browser to scan the information identification code or read the information identification chip through the chip reader to obtain the blockname of the block where the pre-hospital emergency information of the patient is located, and further obtain the pre-hospital emergency information of the patient according to the blockname of the block where the pre-hospital emergency information of the patient is located.

Therefore, when the identity of the patient cannot be known, the information identification code or the information identification chip carried by the patient can be used as the temporary identity of the patient, so that the identity of the patient can be identified in the whole emergency process, and the patient pre-hospital emergency information (the block identification of the block where the emergency information of the patient is located) can be transmitted to staff who carries out subsequent procedures.

In step 706, the medical party reads the block identification from the identification carrier, obtains pre-hospital emergency information, and issues a triage request.

Here, the query request initiated by the medical party and directed against the identification carrier may be a query request initiated by the medical party, and after receiving the query request initiated by the medical party and directed against the identification carrier, the blockchain network reads the blockmark from the identification carrier according to the query request, and further acquires pre-hospital first-aid information corresponding to the patient from a block corresponding to the blockmark in the blockchain network.

The medical side can initiate the triage request on the blockchain browser, after the medical side reads the block identifier from the identifier carrier, the functional keys of the triage can be displayed in the blockchain browser, and the medical side can initiate the triage request by clicking the functional keys of the triage.

In step 707, the blockchain network invokes a triage intelligent contract corresponding to the triage request from the blockchain network according to the triage request, obtains a triage result according to the triage intelligent contract and pre-hospital first aid information, and outputs the triage result to a medical party.

It can be understood that the intelligent contract side chain in the blockchain network can store the diagnosis-dividing intelligent contract, and the diagnosis-dividing intelligent contract can automatically divide the diagnosis of the patient according to the pre-hospital first-aid information of the patient to obtain the diagnosis-dividing result. Here, the triage result may include a severity level of the patient's condition and a graded basis for hit of the level. Here, the triage smart contract may include an NLP algorithm.

In step 708, the medical party performs a post-hospital diagnosis on the patient based on the pre-hospital emergency information and the triage results and uploads the post-hospital diagnosis information to the blockchain network.

Here, after receiving the post-hospital diagnosis information uploaded by the medical party, the blockchain network may perform consensus on the post-hospital diagnosis information through a consensus node in the blockchain network, and after completing the consensus on the post-hospital diagnosis information, save the post-hospital diagnosis information to a block of the blockchain network.

In step 709, after receiving the claim settlement request initiated by the claim settlement party, the blockchain network acquires the relevant information of the patient, invokes the claim settlement intelligent contract to determine whether the patient meets the claim settlement condition, and performs claim settlement under the condition that the patient meets the claim settlement condition.

After receiving the claim settlement request initiated by the claim settlement party, the blockchain network can acquire pre-hospital first aid information, post-hospital diagnosis information, electronic medical records and insurance contracts associated with the identity information of the patient from the blockchain network according to the identity information of the patient carried in the claim settlement request, and call the claim settlement intelligent contract corresponding to the claim settlement request; under the condition that the pre-hospital first-aid information, the post-hospital diagnosis information and the electronic medical record meet the preset conditions through the intelligent contract for claim settlement, the condition that the patient meets the claim settlement conditions in the insurance contract is determined, and the claim settlement is carried out according to the claim settlement mode in the insurance contract.
