Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Fig. 1 is a schematic view of an implementation environment related to a method for querying medical item data based on a blockchain according to an embodiment of the present disclosure. As shown in FIG. 1, the implementation environment may include: a pre-established blockchain network 10, where the blockchain network 10 may include a plurality of nodes 101 (only 4 nodes are shown in fig. 1), each node 101 may be a computer device, and each node 101 may receive input information during normal operation and maintain shared data within the blockchain network 10 based on the received input information. For example, referring to fig. 1, the computer device may be a server, or may also be a terminal such as a desktop computer or a smart phone.

Also, referring to fig. 1, in order to ensure the information intercommunication of the blockchain network 10, a communication connection may be established between the nodes 101, and information transmission may be performed between the nodes 101 through the communication connection.

The communication connection between the nodes is a wireless connection or a wired connection, and the wireless connection may include: wireless Fidelity (WIFI) connection, data connection, bluetooth connection, infrared connection, or the like, and the wired connection may include: universal Serial Bus (USB) connections.

When any node 101 receives data, the data may be broadcast to the entire blockchain network 10 so that other nodes 101 in the blockchain network 10 may receive and store the data, i.e., so that all nodes 101 included in the blockchain network 10 may store the data. Optionally, each node 101 may further have a node identifier corresponding thereto, and may store node identifiers of other nodes in the blockchain network 10 except the node, so that each node 101 may reliably broadcast the received data to the other nodes through the communication connection according to the node identifiers of the other nodes.

For example, referring to table 1, a node identification list maintained in each node 101 is shown, which may include: node name and node identification. The node identifier may be an Internet Protocol (IP) address and any other information that can be used to identify the node, and table 1 only illustrates the IP address as an example. For example, referring to table 1, the node name is node 1, and the node identifier corresponding to the node 1 is: 117.114.151.174.

TABLE 1

Node name	Node identification
		Node 1	117.114.151.174
Node 2	117.116.189.145
		…	…
Node N	119.123.789.258

In order to ensure the consistency of the data stored by each node 101, each node 101 may also maintain the entire blockchain network 10 based on a set of consensus mechanisms. That is, the nodes 101 may perform data correction for multiple times through a pre-configured consensus algorithm, and continuously broadcast the data that is corrected for the last time to the whole network until the data stored by the nodes 101 are consistent, that is, until the nodes 101 achieve consensus.

The principle of the consensus algorithm comprises the following steps: the node receiving the data compares the received data with the data stored in the node, and the data with the accuracy rate larger than the accuracy rate threshold value in the plurality of data determined after comparison is broadcasted to the whole network again; then, the node receiving the corrected data continues to repeatedly perform the comparison operation, i.e., perform network diffusion iteration until the whole network is agreed.

For example, in the embodiment of the present application, a target node that receives medical item data for the first time may broadcast the medical item data to the entire network, and any node that receives medical item data sent by the target node may compare the received medical item data with medical item data that is stored in advance by itself (i.e., identify the medical item data), and broadcast more accurate medical item data after comparison to the entire network again. Any node which receives the corrected medical item data continuously compares the corrected medical item data with the medical item data stored in advance, broadcasts the more correct medical item data to the whole network again, and continuously and repeatedly executes the steps until the medical item data stored in all the nodes in the network are consistent.

It should be noted that, in the embodiment of the present application, the blockchain network 10 may be a decentralized network system, i.e., the donation records may be managed by the blockchain network 10 in a decentralized technology. Wherein, decentralization means: there is no concept of a central node in the blockchain network 10, the positions of the nodes 101 in the blockchain network 10 are equal, each node 101 may store the same blockchain, each blockchain includes a plurality of blocks, each block stores different data, and the data stored in all the blocks on the blockchain constitute all the shared data of the blockchain network.

Referring to fig. 2, a terminal 01 of a medical institution and a terminal 02 of a physical examination institution, which examine a user, may be connected to the blockchain network 10. Of course, the user's terminal 03 and the physician's terminal 04 diagnosing the user may also be connected to the blockchain network 10. Alternatively, the medical institution's terminal 01, the physical examination institution's terminal 02, the user's terminal 03, and the physician's terminal 04 may all be nodes in the blockchain network 10. The terminal can be a smart phone, a notebook computer, a desktop computer or a tablet computer. The storage and query of the medical item data can be realized through the block chain technology, and compared with a method for repeatedly checking the medical items by a user due to non-intercommunicating information in the related technology, the method can save medical resources and has higher acquisition efficiency of the medical item data.

Fig. 3 is a flowchart of a method for querying medical item data based on a blockchain according to an embodiment of the present application. The method may be applied in a target node in a blockchain network, which may be any node in the blockchain network 10. Referring to fig. 3, the method may include:

step 201, acquiring target medical item data of a target user.

In this embodiment of the application, if the detection terminal is not a certain node in the blockchain network but a terminal connected to a target node in the blockchain network, the detection terminal may upload the target medical item data of the target user to the target node, and the target node may obtain the target medical item data of the target user uploaded by the detection terminal. For example, a medical client for storing and querying medical item data may be installed in the detection terminal, and a user may upload target medical item data of a target user to a target node through the medical client, so that the target node may acquire the target medical item data of the target user.

If the detection terminal is a target node in the blockchain, the target project data of the target user can be uploaded to the detection terminal by the target user or a doctor of the target user. For example, a medical client may be installed in the detection terminal, and the target user or a physician of the target user may upload target medical item data of the target user through the medical client.

The target medical item data may include: an identification of the target user, and a detection of the at least one medical item. The terminal of the target user may be installed with a medical client, and the user may register in the blockchain network through the medical client, and the identifier of the target user may be an account number assigned during registration. The medical items may include: height, weight, blood sample test, ultrasonic test, and electrocardiogram test.

Step 202, broadcasting the target medical item data to other nodes in the blockchain network so as to write the target medical item data of the target user into the blockchain network.

In the embodiment of the application, after the target node acquires the target medical item data of the target user, the acquired target medical item data may be broadcast to other nodes in the block chain network. That is, the target node that acquires the target medical item data of the target user may transmit the target medical item data to other nodes through communication connection established with other nodes, so as to write the target medical item data of the target user into the blockchain network, so that each node in the blockchain network may store the target medical item data.

Optionally, in order to ensure consistency of information stored by each node in the blockchain network, other nodes that acquire the target medical item data from the target node may perform consensus processing on the target medical item data through a consensus algorithm, and then broadcast the target medical item data to the whole network again, and continuously execute the consensus processing until the target medical item data stored by each node are consistent.

Step 203, in response to the data query request carrying the identification of the target user, determining a target medical item from at least one medical item.

In the embodiment of the application, if a target user, a physician, a physical examination institution or a medical institution needs to query target medical item data of the target user, a data query request carrying an identifier of the target user can be triggered through a query terminal. Accordingly, the target node may determine a target medical item from the at least one medical item in response to the data query request. If the query terminal is not a node in the blockchain network, the query terminal may send the data query request to the target node. If the query terminal is a node in the block chain network, the data query request may be generated by a user through triggering of a medical client installed in the query terminal.

It should be noted that the query terminal may be a terminal of a query user who queries the target medical item data. Wherein, the query user can be the target user. That is, the target user can query the target medical item data of the target user through the blockchain network, so that the target user can know the body state of the target user in time, and doctor-patient disputes are effectively avoided. Alternatively, the querying user may be a medical facility, physical examination facility or physician. That is, the medical institution, the physical examination institution or the physician can also know the target medical item data of the target user through the blockchain network, so as to conveniently make a next treatment plan for the target user according to the target medical item data.

And step 204, determining the detection result of the target medical item.

In the embodiment of the application, after the target node determines the target medical item, the detection result of the target medical item can be determined, and the query user can view the detection result through the query terminal.

It should be noted that the target node may further determine a detection result of each medical item in the target medical item data of the target user, that is, the query user may view detection results of other medical items in addition to the detection result of the target medical item, so that the query user may comprehensively know the physical state of the target user.

It should be noted that, if the query terminal is not a node in the blockchain network, the target node may send the detection result of the target medical item to the query terminal. If the query terminal is a node in the block link network, the query terminal may directly display the detection result of the target medical item in the query terminal after determining the detection result of the target medical item.

In summary, the present application provides a method for querying medical item data based on a blockchain, which may first obtain target medical item data of a target user, and broadcast the target medical item data to other nodes in a blockchain network. Then, the detection result of the target medical item can be determined in response to the data query request carrying the identification of the target user. Because the target medical item data of the target user can be stored in the blockchain network, the inquiring user who needs to inquire the target medical item data of the target user can directly acquire the target medical item data from the blockchain network without the need of repeatedly checking medical items by the target user, and thus medical resources are saved.

Fig. 4 is a flowchart of a method for querying medical item data based on a blockchain according to an embodiment of the present application. The method may be applied in an implementation environment as shown in fig. 2. In the following description, each terminal in the implementation environment is a terminal connected to a target node in the blockchain network, that is, each terminal is not a node in the blockchain network. As can be seen with reference to fig. 4, the method may include:

step 301, the first detection terminal sends a registration request to the target node.

In an embodiment of the present application, the first detection terminal may generate a registration request and send the registration request to a target node in the blockchain network 10 through a communication connection with the target node. The first detection terminal can be provided with a medical client for storing and inquiring medical project data, and the uploading user can trigger the first detection terminal to send a registration request to the target node through the medical client.

It should be noted that the first detection terminal may be one of the medical institution terminal, the physical examination institution terminal, and the physician's own terminal shown in fig. 2. That is, the terminal of the medical institution, the terminal of the physical examination institution, and the terminal of the doctor themselves can upload the target medical item data of the target user to the target node in the blockchain network.

Step 302, the target node generates a key pair in response to the registration request.

In this embodiment of the present application, after receiving the registration request sent by the first detection terminal, the target node may generate a unique key pair for the target node in response to the registration request. Wherein the key pair may include a public key and a private key.

For example, the target node may randomly generate a private key in response to the registration request, and encrypt the private key using an encryption algorithm to obtain a public key. The private key may be a password for logging in the blockchain network, and the public key may be an account for logging in the blockchain network. In addition, the private key can also be used for signing the information sent by the first detection terminal by the block chain network, and the public key can also be used for verifying the information sent by the first detection terminal by the block chain network.

Step 303, the target node sends the key pair to the first detection terminal.

In this embodiment, after the target node generates the key pair, the target node may send the key pair to the first detection terminal, so that the first detection terminal stores the key pair. The key pair can be used for the first detection terminal to log in the blockchain network by taking a public key as an account and a private key as a password. After receiving the key pair, the first detection terminal may confirm that the registration is successful.

Optionally, after sending the key pair to the first detection terminal, the target node may send the public key in the key pair to other nodes in the blockchain network, after receiving the public key, any node may perform consensus on the public key through a consensus algorithm and then broadcast the public key to the blockchain network again, and continuously and repeatedly perform the consensus until the public keys stored by all nodes in the blockchain network are consistent, so that consistency of the public keys stored by each node in the blockchain network can be ensured.

And step 304, the first detection terminal sends mechanism information to the target node.

In this embodiment of the application, after the first detection terminal completes registration, the mechanism information of the first detection terminal may be uploaded to a target node of the block chain network, and the target node may obtain the mechanism information uploaded by the first detection terminal and store the mechanism information. Wherein, referring to fig. 5, the organization information 40 may include: the institution identification 401 of the institution to which the first detection terminal belongs, the establishment time 402, the qualification 403, the department information 404, and the physician information 405. The organization identity 401 may be the name of the organization.

Optionally, the first detection terminal may send the mechanism information of the first detection terminal to the target node through a communication connection with the target node, so that the target node stores the mechanism information.

It should be noted that the qualification of the organization to which the first detection terminal belongs may refer to the qualification of the organization, and the department information may include: department name, and department rating. Referring to fig. 6, physician information 405 may include: the physician in the facility has a job designation 4051, medical information 4052, and a visit volume 4053. The medical information 4052 may be a resume of a physician, among others.

And 305, the first detection terminal sends the target medical item data of the target user to the target node.

In the embodiment of the application, the first detection terminal may upload the target medical item data of the target user to the target node, and the target node may acquire the target medical item data of the target user uploaded by the first detection terminal. Wherein the first detection terminal may be one of a terminal of a medical institution, a terminal of a physical examination institution, and a terminal of a doctor himself/herself as shown in fig. 2. That is, the terminal of the medical institution, the terminal of the physical examination institution, and the terminal of the doctor themselves can upload the target medical item data of the target user to the target node in the blockchain network.

The first detection terminal can upload target medical item data encrypted by a private key, namely the target medical item data uploaded by the first detection terminal are encrypted by the private key. Referring to fig. 7, the target medical item data 50 may include: the identification 501 of the target user, the institution information 40 of the institution to which the first detection terminal belongs, the detection substance code 502 of the target user, the identification 503 of at least one medical item, and the detection result 504 of at least one medical item.

The identifier of the target user may be an account allocated during registration. The identification of each medical item may be the name of the medical item. The medical items may include: height, weight, blood sample test, ultrasonic test, and electrocardiogram test.

As a possible case, the diagnosis result of each medical item may be obtained by a doctor according to the detection result of the medical item. Referring to fig. 7, the target medical item data 50 may further include: a diagnostic result 505 of at least one medical item. That is, the diagnosis result 505 of the at least one medical item may be uploaded to the target node by the first detection terminal. The number of the detection results may be equal to the number of the medical items, that is, each medical item has a detection result. The number of diagnostic results may be less than or equal to the number of medical items, i.e. some medical items may have only test results and no diagnostic results.

As another possible case, the target medical item data of the target user sent by the first detection terminal to the target node does not include the diagnosis result. When the user acquires the target item data of the target user from the blockchain network for subsequent query, the diagnosis result of the medical item in the target item data of the target user can also be acquired, and a diagnosis model can be stored in the target node in advance. The diagnosis result of each medical item may be determined by the target node according to the detection result of the medical item and a diagnosis model stored in the target node in advance, and the diagnosis model may be trained based on a sample of the detection results of a plurality of medical items for which the diagnosis result has been determined. That is, the diagnosis model may automatically determine the diagnosis result of the medical item according to the detection result of the medical item in the target medical item data of the target user uploaded by the first detection terminal.

Of course, the target medical item data of the target user sent to the target node by the first detection terminal includes a diagnosis result, and the diagnosis model stored in the target node in advance may also automatically determine the diagnosis result of the medical item according to the detection result of the medical item in the target medical item data of the target user uploaded by the first detection terminal. That is, the diagnosis model in the target node may automatically determine the diagnosis result regardless of whether the first detection terminal sends the target medical item data of the target user to the target node, wherein the target medical item data includes the diagnosis result.

The diagnostic result may include: the name of the disease that the target user may have, a description of the symptoms, follow-up detection recommendations, and treatment recommendations. The detection substance may be blood, urine, or the like, and the detection substance code may be a character string uniquely indicating the detection substance, and may be a unique number, for example.

Optionally, if the diagnosis result is obtained by a doctor according to the detection result of the medical item, the diagnosis result may further include information of the doctor providing the diagnosis result.

And step 306, the target node decrypts the encrypted target medical item data by adopting the public key.

In this embodiment, the target node may decrypt the encrypted target medical item data by using a public key in a key pair generated for the first detection terminal to obtain decryption information. And if the decryption information is the target medical item data, the target node determines that the signature verification is successful. That is, the target node may determine that the target medical item data was sent by the first detection terminal. If the decryption information is not the target medical item data, the target node determines that the signature verification fails, and the target node can ignore the decryption information.

Step 307, the target node broadcasts the target medical item data to other nodes in the blockchain network, so as to write the target medical item data of the target user into the blockchain network.

In this embodiment of the application, after determining that the target medical item data is sent by the first detection terminal, the target node may broadcast the target medical item data to other nodes in the blockchain network, that is, the target node that acquires the target medical item data of the target user may transmit the target medical item data to the other nodes through communication connection established with the other nodes, so as to write the target medical item data of the target user into the blockchain network, and each node in the blockchain network may store the target medical item data.

Step 308, the query terminal sends a data query request carrying the identifier of the target user to the target node.

In the embodiment of the application, if a target user, a doctor, a physical examination institution or a medical institution needs to query target medical item data of the target user, a data query request carrying an identifier of the target user may be sent to a target node through a query terminal.

Step 309, the target node responds to the data query request carrying the identification of the target user sent by the query terminal, and determines the target medical item from at least one medical item.

In the embodiment of the application, after the query terminal sends the data query request carrying the identifier of the target user to the target node, the target node can receive the data query request and determine the target medical item from at least one medical item in response to the data query request.

It should be noted that the query terminal may be a terminal of a query user who queries the target medical item data. Wherein, the query user can be the target user. That is, the target user can query the target medical item data of the target user through the blockchain network, so that the target user can know the body state of the target user in time, and doctor-patient disputes are effectively avoided. Alternatively, the querying user may be a medical facility, a physical examination facility, or a physician. That is, the medical institution, the physical examination structure or the physician can know the target medical item data of the target user through the blockchain network, so as to conveniently make a next treatment plan for the target user according to the target medical item data.

In the embodiment of the present application, the target medical item determined by the target node may be any medical item. Alternatively, the target medical item determined by the target node may be a medical item recently stored in the target node in the target medical data of the target user. Or, the data query request may carry an identifier of the target medical item, and the target node may determine the target medical item directly according to the identifier. The query terminal can be provided with a medical client, and a query user can trigger the query terminal to send a data query request to the target node through the medical client.

It should be noted that the difference between the detection result of the target medical item determined by the target node and the standard result may be greater than the difference threshold. That is, the target medical item may be a medical item with an abnormal detection result, and needs to be focused. Alternatively, each node in the blockchain network may store a standard result for each medical item, as well as a difference threshold, and the standard result and the difference threshold may be determined empirically.

At step 310, the target node determines at least one candidate medical item data from the medical item data of the plurality of users.

In the embodiment of the present application, medical item data of a plurality of users may be stored in the target node. The target node may determine at least one candidate medical item data from the medical item data of the plurality of users based on the determined target medical item.

And the similarity between the detection result of the target medical item in each candidate medical item data and the detection result of the target medical item in the target medical item data is greater than a similarity threshold value. That is, the target node may obtain the detection result of the target medical item in the candidate medical item data having a higher similarity to the detection result of the target medical item in the target medical item data. Alternatively, the similarity threshold may be preset by the target node.

And 311, the target node generates statistical information of the target medical item according to the diagnosis result of the target medical item in the at least one candidate medical item data.

In this embodiment of the application, the target node may further store a diagnosis result of each medical item in the plurality of medical item data, and the target node may generate statistical information of the target medical item according to the diagnosis result of the target medical item in the at least one candidate medical item data.

Wherein the statistical information may include: the type of diagnosis determined from the at least one candidate medical item data may further include at least one of a number and a percentage of diagnosis of each type. Wherein the type of diagnostic result may refer to the type of disease. The number of diagnostic results for each type may be used to reflect the number of users for which the diagnostic result for the medical item is of that type. The percentage may be used to reflect the distribution of diagnostic results. The percentage may be a ratio of the number of diagnosis results of each type to the number of candidate medical item data.

For example, it is assumed that the index of the detection result of the target medical item of the target user is 20% higher than the standard result, the determined candidate medical item data includes 10, and the types of the diagnosis results are determined to be 3 according to the diagnosis result of the target medical item in the 10 candidate medical item data. Referring to fig. 8, the statistical information shows that the first type XX has 7 diagnosis results accounting for 70%, the second type YY has 2 diagnosis results accounting for 20%, and the third type ZZ has 1 diagnosis result accounting for 10%.

Step 312, the target node sends the detection result, diagnosis result, and statistical information of the target medical item to the query terminal.

The target node may send the relevant information (the detection result, the diagnosis result, and the statistical information) of the target medical item to the query terminal, so that the query user can know the relevant information of the target medical item in the target medical item data of the target user in time through the query terminal.

In the embodiment of the application, if the difference value between the detection result of the target medical item determined by the target node and the standard result is greater than the difference threshold, the target medical item is a medical item with an abnormal detection result. At this time, the target node may send only the relevant information of the medical item with the abnormal detection result to the query terminal, and does not need to send the relevant information of the medical item with the normal detection result to the query terminal. That is, the query terminal may only display the relevant information of the medical item with the abnormal detection result, so that on one hand, the query user can conveniently and quickly determine the physical state of the target user according to the detection result of the target medical item, and on the other hand, the efficiency of the target node for sending information can be improved.

It should be noted that the target node may also send the relevant information of each medical item in the acquired target medical item data of the target user to the query terminal, that is, the target node may send the relevant information of the target medical item to the query terminal, and may also send the relevant information of other medical items to the query terminal. Besides, the related information of the medical item with the abnormal detection result is displayed before the related information of the medical item with the normal detection result, so that the inquiry user can conveniently know the related information of the medical item with the abnormal detection result in the target medical item data of the target user, and the inquiry user can comprehensively know the physical state of the user.

In this embodiment of the present application, the detection result of the medical item sent by the target node to the query terminal may include: the detection result is normal and the detection result is abnormal. That is, the target node may only send whether each medical item is normal or not to the query terminal, and the query user may determine whether the detection result of each medical item is normal or not through the query terminal. Of course, in order to facilitate the querying user to know the specific situation of each medical item of the target user, the detection result may further include: the target node can also send the detection data of each medical item to the query terminal.

It should be noted that the diagnosis result of the target medical item sent by the target node to the query terminal may be obtained by a doctor according to the detection result of the target medical item, or the target node may be determined according to the detection result of the target medical item and the diagnosis model stored in the target node. Or, the target node may send both a diagnosis result obtained by a doctor according to the detection structure of the target medical item and a diagnosis result automatically determined by the diagnosis model to the query terminal, so that the query user can refer to the diagnosis result diagnosed by the doctor and determine the physical state of the target user according to the diagnosis result automatically determined by the diagnosis model.

Step 313, the second detection terminal sends a check request carrying the identifier of the target user to the target node.

In the embodiment of the present application, the second detection terminal may be a terminal of an acquirer of target medical item data of a target user, for example, the second detection terminal may be a terminal of a human unit. When the target user enters the job, the human unit needs to acquire a physical examination report of the target user. At this time, the second detection terminal may send a check request carrying the identifier of the target user to the target node. The examination request may also carry an identification of a plurality of medical items to be examined. The plurality of medical items to be examined may be medical items of medical item data that the second inspection terminal needs to acquire.

Correspondingly, after the second detection terminal sends the check request carrying the identifier of the target user to the target node, the target node can receive the check request sent by the second detection terminal.

In step 314, the target node determines the medical items except the medical item to which the detection result included in the target medical item data belongs from the plurality of medical items to be checked as the remaining medical items to be checked of the target user.

In the embodiment of the application, since the target user has already completed the detection of some medical items (target medical items), when the second detection terminal needs to acquire the detection result of the target medical item of the target user, the detection result of the target medical item can be directly acquired from the target node, and the target user does not need to perform the detection of the target medical item again. For the medical items that the target user does not complete (remaining medical items to be checked), the target user is required to go to the medical institution or physical examination institution for detection.

For example, assuming that the target user has completed the testing of the medical items identified as K1 and K2, the second testing terminal may obtain the medical item data for the medical items identified as K1 and K2 directly from the target node. And the identification of the plurality of medical items to be examined carried by the examination request includes: k1, K2, K3, K4 and K5. Thus, the target node may determine that the identification of the remaining medical items under investigation of the target user includes: k3, K4 and K5. That is, the target user needs to complete the testing of the medical items identified as K3, K4, and K5.

And 315, the target node sends the identifiers of the remaining medical items to be checked to the second detection terminal.

In the embodiment of the application, after determining the remaining medical items to be checked of the target user, the target node may send the identifiers of the remaining medical items to be checked of the target user to the second detection terminal, so that the second detection terminal can timely acquire the detection condition of the target user.

For example, assuming that the remaining medical items to be investigated include medical items identified as K3, K4, and K5, the target node may transmit the K3, K4, and K5 to the second test terminal.

It should be noted that, after the target user completes the detection of the remaining medical items to be checked, the target node may obtain the remaining medical item data to be checked of the target user, where the medical item data to be checked may include: identification of the target user and detection results of the remaining medical items to be checked.

It should be further noted that, in the embodiment of the present application, the first detection terminal, the query terminal, and the second detection terminal may be different terminals. In order to ensure that the query terminal and the second detection terminal can upload information to the blockchain network or acquire information from the blockchain network, the second detection terminal and the query terminal also need to register on the target node, and the registration process of the second detection terminal and the registration process of the query terminal can be the same as that of the first detection terminal, which is not described herein again in this embodiment of the present application. Of course, the first detection terminal, the query terminal, and the second detection terminal may also be the same terminal, which is not limited in this embodiment of the present application.

It should be further noted that, in the embodiment of the present application, the second detection terminal may also be the target node in the blockchain network. If the second detection terminal is the target node, in step 313, the target node may receive an examination request carrying an identifier of the target user, which is triggered by the target user or a physician of the target user. For example, a medical client may be installed in the second detection terminal, and the examination request may be triggered by the medical client through the target user or a physician of the target user. Accordingly, step 315 may be eliminated and the target node may display an identification of the remaining medical items under examination.

It should also be noted that, in the above method embodiment, the target node may be a fixed node in the blockchain network. Alternatively, since the data stored in each node in the blockchain network is consistent, the target node may not be a fixed node. For example, the target nodes involved in steps 301 to 307 may be the same node, and the target nodes involved in steps 308 to 312 may be the same node and different nodes from the target node involved in step 301.

It should be further noted that, in the method for querying medical item data based on a block chain provided in this embodiment of the present application, the order of steps may be appropriately adjusted, and the steps may also be increased or decreased according to the situation, for example, step 310 and step 311 may be deleted according to the actual situation, correspondingly, step 312 may be to send the detection result and the diagnosis result of the target medical item to the querying terminal for the target node, and step 313 to step 315 may be deleted according to the actual situation. Any method that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application is covered by the protection scope of the present application, and thus the detailed description thereof is omitted.

In summary, the present application provides a method for querying medical item data based on a block chain, where the method may first obtain target medical item data of a target user uploaded by a first detection terminal, and broadcast the target medical item data to other nodes in a block chain network. And then, in response to a data query request which is sent by the query terminal and carries the identification of the target user, sending the detection result of the target medical item to the query terminal. Because the target medical item data of the target user can be stored in the blockchain network, the query user who needs to query the target medical item data of the target user can directly acquire the target medical item data from the blockchain network through the query terminal without repeatedly checking medical items by the target user, and thus medical resources are saved.

In addition, the target node can determine the target medical item with an abnormal detection result and send the target medical item to the query terminal through the detection result of the target medical item, so that the method provided by the application not only can facilitate the query user to quickly determine the body state of the target user according to the detection result of the target medical item, but also can improve the efficiency of sending the detection result by the target node.
