[0038] Figure 1 This illustration shows a flowchart of a blockchain-based drug management method according to an embodiment of this disclosure. This embodiment can be applied to electronic devices, such as... Figure 1 As shown, the blockchain-based drug management method in this embodiment includes the following steps:
[0039] Step S110: The seller receives the purchase request sent by the buyer.
[0040] The drug purchase request includes: the buyer's identifier and the drug identifier to be purchased.
[0041] A drug identifier uniquely identifies a drug and includes the storage address of drug information, which can be retrieved from the blockchain based on this address. A buyer identifier uniquely identifies a buyer and includes the storage address of buyer information, which can be retrieved from the blockchain based on this address. Buyer information may include: prescription information, drug purchase information, and identity information. Both drug identifiers and buyer identifiers can be barcodes, QR codes, DID (Decentralized Identifier), etc. Sellers can be retail pharmacies, and buyers can be patients or other individuals.
[0042] Step S120: The seller obtains the drug information of the drug to be purchased on the blockchain based on the drug identifier.
[0043] The drug information includes: the name of the drug to be purchased, the method of administration, and the category.
[0044] The drug name can be the Chinese name or English name of the drug to be purchased. Dosage information can include the usage and dosage of the drug. For example, the dosage information for drug A could be: Usage: Oral, can be chewed; Dosage: Three times daily, one tablet each time. Category information can include the category to which the drug belongs. Category information can be created based on the drug's properties, such as side effects, activity, and dependence; or based on whether the drug is a prescription drug; or based on the specific circumstances. For example, category information could be hypoglycemic, antihypertensive, prescription, etc.; or it can be custom category information, such as category information A, category information B, etc. Category information can be stored in the form of a drug category information table, which can include the drug name and the category information corresponding to each drug name; then, the drug's category information can be determined based on the drug category information table.
[0045] In one implementation, drug information may further include: the drug label, manufacturer, ingredients, adverse reactions, precautions for use, expiration date, approval number, transportation information, and storage information of the drug to be purchased. This drug information can be uploaded by the seller or manufacturer to a blockchain (the storage address included in the drug label) for storage. Drug information can be retrieved from the blockchain based on the storage address of the drug information included in the drug label.
[0046] In step S130, in response to the fact that the category information of the medicine to be purchased is preset category information, the prescription information and medicine purchase information of the buyer are obtained from the blockchain based on the buyer's identifier.
[0047] The preset category information can be set according to the actual situation. For example, the preset category information can be prescription drugs. When it is determined that the category information of the drug to be purchased is a prescription drug, the category information of the drug to be purchased can be set to the preset category information.
[0048] Prescription information may include: at least one drug name, dosage, quantity, method of administration, doctor's name, hospital name, and date of prescription. Dosage may include the amount used each time and the daily dosage; for example, dosage could be: three times a day, one tablet each time. Quantity may be the total quantity of each drug used; for example, the quantity of drug A to be purchased could be 3 boxes (30 tablets). Method of administration may be the specific method of use, such as oral administration or topical application. Each buyer can have multiple prescription records. Drug purchase information includes all records of drug purchases by the buyer, and may include: purchase date, quantity purchased, drug name, and the name of the seller.
[0049] In one implementation, the hospital has a terminal that has been certified by the blockchain. Doctors can upload the prescription information they issue to the blockchain through the terminal, and at the same time, the doctors will also send the prescription information to the purchaser.
[0050] In one implementation, when the category information of the medicine to be purchased is not the preset category information, the seller can directly sell the medicine to the buyer.
[0051] Step S140: Based on the prescription information, determine whether there is any prescription information that meets the preset prescription screening criteria.
[0052] Among them, the preset prescription screening conditions can be the conditions for screening prescription information, and the preset prescription screening conditions can be set according to the actual situation.
[0053] In one implementation, all prescription information can be traversed to determine whether there is any prescription information containing a drug name that is the same as the drug name to be purchased in the drug information. When it is determined that there is a prescription information containing a drug name that is the same as the drug name to be purchased in the drug information, it is determined that there is prescription information that meets the preset prescription screening conditions.
[0054] Step S150: In response to the presence of prescription information that meets the preset prescription screening criteria in the prescription information, determine whether there are any drug purchase records in the drug purchase information for purchasing drugs within a preset time period, based on the drug purchase records in the drug purchase information.
[0055] The drug purchase information can include at least one drug purchase record. Each drug purchase record can include: the date of purchase, the quantity of drug purchased, the name of the drug purchased, and the name (or identifier) of the seller of the drug. The preset time period can be set according to actual needs; for example, the preset time period can be one week.
[0056] In one implementation, it can be determined whether there is a drug purchase record in the drug purchase information that includes the name of the drug to be purchased. When it is determined that there is a drug purchase record that includes the name of the drug to be purchased, this drug purchase record is designated as the target record. When the number of target records is greater than one, it can be determined whether the time interval between the purchase date in the most recent target record and the current date is less than a preset time period. If it is less than the preset time period, it can be determined that there is a drug purchase record in the drug purchase information that purchased the drug to be purchased within the preset time period. When the number of target purchase records is one, it can be determined directly based on the purchase date and the current date in the target record whether there is a drug purchase record in the drug purchase information that purchased the drug to be purchased within the preset time period. When it is determined that there is no drug purchase record that includes the name of the drug to be purchased, it can be determined that there is no drug purchase record in the drug purchase information that purchased the drug to be purchased within the preset time period.
[0057] Step S160: In response to the existence of drug purchase records for drugs purchased within a preset time period in the drug purchase information, determine whether the purchaser meets the preset drug purchase conditions based on the drug purchase information and medication method information.
[0058] In one implementation, the most recent drug purchase record of the drug to be purchased in the drug purchase information can be used as the target purchase record; the dosage of the drug to be purchased can be determined from the medication method information of the drug to be purchased.
[0059] Based on the purchase date and quantity of the medicine in the target purchase record, as well as the current date and medicine usage, determine the remaining quantity of the medicine to be purchased corresponding to the target purchase record. When the remaining quantity is less than or equal to the preset remaining quantity, it is determined that the purchaser meets the preset medicine purchase conditions.
[0060] In one implementation, when it is determined that there is no drug purchase record in the drug purchase information for purchasing the drug to be purchased within a preset time period, the seller sells the drug to the buyer.
[0061] In step S170, in response to the buyer meeting the preset drug purchase conditions, the seller sells the drug to the buyer.
[0062] Specifically, when it is determined that the buyer meets the preset drug purchase conditions, the seller sells the drug to the buyer.
[0063] In one implementation, after the seller sells the medicine to the buyer, the seller generates a medicine purchase record for this transaction and updates the medicine purchase record to the buyer's medicine purchase information.
[0064] In one practical approach, the seller will not sell the medicine to the buyer if it is determined that the buyer does not meet the preset conditions for purchasing the medicine.
[0065] In this embodiment, combining the drug information to be purchased with the purchaser's prescription and purchase information not only allows for determining whether to sell the drug to the purchaser based on their current medication history, ensuring medication safety, but also enables processing of drugs in preset categories and direct sale of drugs in non-preset categories, further ensuring medication safety and improving sales efficiency. Furthermore, this embodiment records the final stage of drug distribution through purchase information, thus perfecting the drug distribution information chain.
[0066] In one alternative embodiment, such as Figure 2 As shown, step S160 in this embodiment may include the following steps:
[0067] Step S161: Obtain the most recent drug purchase record of the drug to be purchased from the drug purchase information as the target purchase record.
[0068] The target purchase record includes: the date of purchase and the quantity of medicine purchased.
[0069] The target purchase record may also include: the name of the purchased drug and the name (or identifier) of the seller of the purchased drug. Purchase records that include the same name as the drug to be purchased can be identified as purchase records for the drug to be purchased.
[0070] When the number of drug purchase records for a drug to be purchased is greater than one, the most recent drug purchase record for that drug will be selected as the target purchase record. When the number of drug purchase records for a drug to be purchased is equal to one, that drug purchase record will be selected as the target purchase record.
[0071] For example, when there are two drug purchase records for drug A to be purchased, these two drug purchase records are drug purchase record a and drug purchase record b, respectively. The purchase date in drug purchase record a is March 15, 2021, and the purchase date in drug purchase record b is January 7, 2021. Then, drug purchase record a is determined as the target purchase record.
[0072] Step S162: Based on the target purchase record, current date, and medication method information, determine whether the quantity of medicines to be purchased has been used up.
[0073] Specifically, it can be determined whether the buyer has used up the purchased drugs according to the purchase date and quantity in the target purchase record, as well as the dosage in the current date and medication method information.
[0074] For example, if the purchase date in the target purchase record is March 15, 2021, the quantity purchased is 1 box (16 tablets), the current date is April 4, 2021, and the dosage in the medication instructions is: 2 times a day, one tablet each time.
[0075] Based on the purchase date and the current date in the target purchase record, it can be determined that the interval between the purchase date and the current date is 20 days. Based on the dosage, the daily dosage is 2 tablets. Based on the purchase quantity (16 tablets), the interval (20 days), and the daily dosage (2 tablets), it can be determined that the medicine to be purchased has been used up by the current date.
[0076] Step S163: In response to the exhaustion of the purchased drugs in the quantity ordered, determine that the purchaser meets the preset drug purchase conditions.
[0077] When the quantity of medicines to be purchased is used up and it is determined that the buyer meets the preset purchase conditions, the seller will sell the medicines to the buyer.
[0078] In one implementation, if the quantity of medicines to be purchased is not used up, it is determined that the buyer does not meet the preset purchase conditions, and the seller will not sell the medicines to the buyer.
[0079] In this embodiment of the disclosure, based on the purchaser's most recent drug purchase record, as well as the current date and medication method information, it is determined whether the purchaser has used up the most recent purchased drug. Once it is determined that the drug has been used up, it is determined that the drug can be sold to the purchaser. This effectively ensures that the drug is sold to the purchaser when the drug has been used up. This not only improves the purchaser's medication safety but also enables effective monitoring of the purchaser's drug usage. It can promptly detect whether the purchaser has exceeded the dosage specified in the medication method information, further guaranteeing the purchaser's medication safety.
[0080] In one alternative embodiment, such as Figure 3 As shown in this embodiment, the drug purchase request further includes: the purchaser's prescription information; step S140 may include the following steps:
[0081] Step S141: Based on the prescription information and drug information, determine whether there is prescription information that includes the name of the drug to be purchased.
[0082] The purchaser's prescription information may include: at least one drug name, drug dosage, quantity of drug, method of drug use, doctor's name, hospital name, and date of prescription.
[0083] When a prescription contains a drug name that is identical to the name of the drug to be purchased, it is determined that the prescription contains prescription information that includes the name of the drug to be purchased.
[0084] Step S142: In response to the existence of prescription information containing the name of the drug to be purchased, the prescription information containing the name of the drug to be purchased is determined as the target prescription information.
[0085] Among them, prescription information that includes the same name as the drug to be purchased is identified as target prescription information.
[0086] Step S143: Determine whether the target prescription information matches the purchaser's prescription information.
[0087] In one implementation, multiple first key fields of the target prescription information and multiple second key fields of the buyer's prescription information can be obtained. The first key fields can be all drug names, drug dosages, drug quantities, doctor names, and prescription dates in the target prescription information; the second key fields can be all drug names, drug dosages, drug quantities, doctor names, and prescription dates in the target prescription information. A hash calculation is performed on the multiple first key fields to obtain first hash values, and a hash calculation is performed on the multiple second key fields to obtain second hash values. The first hash values and second hash values are compared. If the first hash value and the second hash value are the same, the target prescription information is determined to match the buyer's prescription information. Alternatively, if the drug name, drug dosage, drug quantity, and doctor name in the target prescription information are the same as those in the target prescription information, the target prescription information matches the buyer's prescription information.
[0088] It should be noted that when there are multiple target prescription information, each target prescription information needs to be matched with the purchaser's prescription information. When there is a target prescription information that matches the purchaser's prescription information among the multiple target prescription information, it can be determined that the target prescription information matches the purchaser's prescription information.
[0089] Step S144: In response to the matching of the target prescription information and the purchaser's prescription information, determine that there is prescription information in the prescription information that meets the preset prescription screening conditions.
[0090] Specifically, when it is determined that the target prescription information matches the purchaser's prescription information, it is determined that the prescription information contains prescription information that meets the preset prescription screening conditions.
[0091] In one alternative embodiment, such as Figure 4 As shown in this embodiment, the drug purchase request further includes: the quantity of drugs to be purchased; step S163 may include the following steps:
[0092] Step S1631: In response to the use up of the purchased drugs, based on the quantity of drugs purchased and the prescription information of the purchaser, determine whether the quantity of drugs used in the prescription information of the purchaser is greater than or equal to the quantity of drugs purchased.
[0093] The purchaser's prescription information may include: Quantity of medication. The quantity of medication can be the total quantity of each type of medication used. The quantity of medication to be purchased is the total quantity of medications the purchaser intends to buy. The purchaser's prescription information may include multiple quantities of medication, one quantity corresponding to each medication to be purchased.
[0094] Step S1632: In response to the purchaser's prescription information showing a quantity of medication greater than or equal to the quantity of medication purchased, determine that the purchaser meets the preset medication purchase conditions.
[0095] Specifically, when the target purchase record is determined to be used up, the quantity of the medicine to be purchased included in the purchaser's prescription information can be obtained from the purchaser's prescription information. The quantity of medicine to be purchased is compared with the quantity used. When the quantity of medicine to be purchased in the purchaser's prescription information is greater than or equal to the quantity of medicine to be purchased, it is determined that the purchaser meets the preset medicine purchase conditions.
[0096] In one alternative embodiment, such as Figure 5 As shown in this embodiment, the drug purchase request further includes: the public key of the hospital's public-private key pair; the prescription information has a signature generated using the private key of the hospital's public-private key pair;
[0097] The blockchain-based drug management method in this embodiment may include the following steps:
[0098] In step S210, the seller uses the public key to verify the signature of the prescription information.
[0099] The hospital can be a hospital or related medical institution, and it has the authority to issue prescriptions. The hospital can create its public-private key pair using asymmetric encryption algorithms, SM2 national cryptographic algorithm, etc. The public-private key pair includes a public key and a private key. The private key is used for signing, for example, signing prescription information using the private key. The public key is used to verify the signature generated using the private key in the public-private key pair.
[0100] In one practical approach, the hospital issues a prescription to the buyer, generates a copy of the prescription information identical to the original prescription, and sends this copy to the buyer as their prescription information. The hospital then signs the prescription information using the private key from its public-private key pair and uploads the signed prescription information to the blockchain via a terminal authenticated by the hospital. The hospital also sends the public key from its public-private key pair to the buyer.
[0101] Step S220: In response to the presence of a signature of at least one prescription information that has been verified by the public key, perform an operation on the prescription information that has been verified by the signature to determine whether there is any prescription information in the prescription information that meets the preset prescription screening conditions.
[0102] Specifically, the public key in the public-private key pair of the hospital in the drug purchase request is used to verify the signature of all prescription information of the buyer.
