[0067] Continue to refer Figure 2 , shows a flow chart of an embodiment of a volume purchase settlement method according to the present application, comprising the following steps:

[0068] Step S201, the preset settlement payment terminal obtains the agreement to be signed, and obtains the information of the parties to the agreement from the agreement to be signed. The settlement payment terminal sends the agreement to be signed to the main terminal corresponding to the information of the parties to the agreement for signing the agreement, and obtains the signed agreement.

[0069] In this embodiment, the agreement includes contractual documents such as contracts, protocols, and treaties. The parties to the agreement are two or more parties. The information of the parties to the agreement includes basic information of the purchaser and basic information of the supplier.

[0070] The preset settlement and payment terminal can be applied to volume-based procurement. In this embodiment, the settlement and payment terminal is applied to the volume-based procurement of drugs for detailed description. Specifically, the settlement and payment terminal is connected to the external bank terminal, the internal procurement transaction terminal and the drug selection management terminal. The settlement and payment terminal can be divided into the following modules based on product functions:

[0071] (1) Protocol Management Module

[0072] When the government completes the bidding project for volume-based procurement, medical institutions, manufacturers, and distribution companies can sign a three-party / two-party agreement online. The agreement details are updated in real time. In addition to viewing the agreement performance amount, validity period, related bidding batches, and bidding drug catalog, you can also check the progress of the agreement in real time, such as the amount of drugs purchased, the degree of completion of procurement, and the progress of the agreement period.

[0073] (2) Prepayment Management Module

[0074] After a valid agreement is generated, the prepayment amount for each agreement is generated based on the configured prepayment ratio for the Medical Insurance Bureau to complete the online prepayment payment. Users can query the prepayment status of each agreement in real time.

[0075] (3) Account reconciliation management module

[0076] According to the configured review date (reconciliation date), medical institutions and enterprises can complete the detailed review of the bill online, and support online adjustment and re-review of controversial details. The bill reviewed by the agreement party can be paid online by the payer (medical institution) to the enterprise.

[0077] (4) Settlement configuration module

[0078] Configure the settlement period, prepayment date, and reconciliation date for each batch of drugs in the volume-based procurement catalog for the settlement and payment system.

[0079] (5) Payment Management Module

[0080] By connecting with the Bank-Enterprise Link, you can query the dynamic information of the regulatory account opened in the bank, including details of each transaction, account details, payment order details, etc.

[0081] The agreement to be signed includes four major parts: basic agreement information, agreement parameter information, purchased goods information, and consignee information. The basic agreement information is used to record the basic contact information of the agreement signed online / offline, mainly for the convenience of query and retrieval. Its contents include the agreement name, agreement number, volume purchase batch, purchaser name, supplier name, delivery address, remarks, agreement documents, purchaser basic information and supplier basic information; the agreement parameter information is related to the reconciliation, settlement and payment parameters in the settlement and payment end, and is the main parameter for review and confirmation. Its contents include reconciliation method, reconciliation date, settlement method, settlement cycle, pricing method, default payment method, base price reference date, invoicing method, amount of arrears, overdue interest, breach of contract liability and performance liability.

[0082] In this embodiment, the settlement and payment end obtains the agreement to be signed from the drug selection and management end, obtains the information of the parties to the agreement from the agreement to be signed, and sends the agreement to be signed to the main terminal corresponding to the information of the parties to the agreement for signing the agreement. After the main terminal signs the agreement, it obtains the signed agreement and uploads the signed agreement to the settlement and payment end.

[0083] It should be understood that the parties to the agreement include the purchaser and the supplier, and correspondingly, the subject terminal includes the purchase subject terminal and the supply subject terminal. Specifically, the purchaser is a medical institution and the supplier is a drug supply enterprise.

[0084] It should be emphasized that in order to further ensure the privacy and security of the signed agreement, the above-mentioned signed agreement can also be stored in a node of a blockchain.

[0085] The blockchain referred to in this application is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, encryption algorithm, etc. Blockchain is essentially a decentralized database, a string of data blocks generated by cryptographic methods. Each data block contains a batch of network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block. Blockchain can include the underlying blockchain platform, platform product service layer, and application service layer.

[0086] Step S202, the settlement payment end obtains the agreement amount information from the signed agreement, determines the agreement prepayment amount according to the agreement amount information, and initiates a prepayment request to the handling agency service end.

[0087] In this embodiment, the handling agency is the medical insurance center, and the handling agency service end is the medical insurance center service end. In order to ensure timely payment, after the medical institution (purchaser) and the selected drug and medicine enterprise (supplier) sign a purchase agreement, the total agreement amount is obtained according to the agreement amount information. The medical insurance center pays the agreement prepayment amount to the medical institution according to the prepayment ratio. The formula is as follows:

[0088] Agreement prepayment amount = agreement total amount * prepayment ratio

[0089] Among them, the prepayment ratio can be configured at the settlement payment end.

[0090] Step S203, when receiving the prepayment request, the handling agency service end pays the agreement prepayment amount to the purchaser's supervision account of the bank terminal, wherein the purchaser's supervision account is obtained from the agreement party information.

[0091] In this embodiment, the service end of the handling agency receives the prepayment request sent by the settlement payment calculator, and pays the agreed amount to the purchaser's supervision account opened by the purchaser at the bank terminal. Specifically, the medical insurance center pays the agreed prepayment amount to the purchaser's supervision account opened by the medical institution at the bank terminal according to the prepayment ratio.

[0092] Step S204, the purchasing transaction end generates order data according to the purchasing information, wherein the purchasing information is generated according to the signed agreement.

[0093] After the agreement is signed, the procurement phase begins. The supplier obtains procurement information from the signed agreement, generates a delivery order based on the procurement information, prepares the corresponding products based on the delivery order, and delivers them to the purchaser. After the purchaser confirms and receives the goods, the procurement is completed.

[0094] In this embodiment, the purchase transaction terminal is used for online ordering, delivery, acceptance, and warehousing. Purchased drug information includes order data, delivery information, return information, etc., which are recorded through the purchase transaction terminal. The purchase transaction terminal can query the order data, delivery information, return information, etc. of each transaction (each agreement). After the settlement payment terminal configures the settlement cycle and reconciliation date, such as monthly settlement, the actual purchase amount of the previous month is settled on the 1st of each month, then the settlement payment terminal regularly queries the purchase data of the previous month in the purchase transaction terminal on the 1st of each month and synchronizes it to the settlement payment terminal.

[0095] In this embodiment, the purchase information may specifically be drug purchase information. Before the purchase transaction terminal generates order data based on the drug purchase information, the purchaser and the supplier purchase drugs based on the signed agreement. The specific steps include:

[0096] Step A: The supplier obtains the purchased drug information from the signed agreement and generates a shipping order based on the purchased drug information.

[0097] The purchased drug information includes the name of the selected drug, the selected drug specification, the selected drug use, the selected drug unit price, and the purchase quantity. The supplier confirms the signed agreement for the order, obtains the corresponding name of the selected drug, the selected drug specification, the selected drug use, the selected drug unit price, and the purchase quantity from the signed agreement for the order, generates a shipping order, and prepares the goods according to the shipping order.

[0098] In step B, the supplier obtains the supplied drugs according to the shipping order, generates a purchase order according to the distribution point information corresponding to the supplied drugs and the purchaser, and distributes them according to the purchase order.

[0099] The purchase order includes the details of the purchased drugs and the information of the distribution points, etc., which are used for delivery management and receipt management. After the purchase order is confirmed, the delivery phase begins. At the same time, the supplier can upload the purchase order to the procurement transaction system, and the purchaser can obtain the purchase order.

[0100] Step C: After the purchaser receives the supplied drugs, it will enter the supplied drugs into the warehouse and complete the purchase order after confirmation.

[0101] The supplier arranges delivery according to the purchase order. The purchaser receives the supplied drugs and invoice, confirms and signs for them. After confirmation, the supplied drugs are put into storage to complete the purchase order.

[0102] It should be noted that after receiving the supplied medicines, the purchase order can be returned according to the actual situation. Specifically, the purchaser can fill out a return form at the purchasing transaction end, and the supplier obtains the return form and confirms it to enter the return process.

[0103] Step S205, the settlement payment end obtains the reconciliation order from the order data of the purchase transaction end, and generates a settlement document according to the reconciliation order.

[0104] Specifically, the settlement payment end determines the reconciliation date according to the preset reconciliation cycle, and determines the order time based on the reconciliation date. The settlement payment end obtains the current order data corresponding to the order time from the procurement transaction end, wherein the current order data is used as the reconciliation order, and the settlement document is generated based on the reconciliation order.

[0105] When the reconciliation cycle is reached, the reconciliation phase begins. The reconciliation cycle is the reconciliation date in the agreement parameters of the signed agreement. For example, if the reconciliation cycle in the signed agreement is from the 20th to the 30th of the month, a reconciliation calculation table is generated every month, and the order time is from the 21st of the previous month to the 20th of this month. The data in the table are the orders from the 21st of the previous month to the 20th of this month. In this way, the orders from the 21st of the previous month to the 20th of this month are the current order data, i.e. the reconciliation orders.

[0106] In step S206, the settlement payment end sends the settlement document to the purchasing entity terminal corresponding to the purchaser and the supply entity terminal corresponding to the supplier for verification, wherein the purchaser and the supplier obtain the information from the agreement parties.

[0107] Before the reconciliation cycle is over, the two parties to the transaction (both parties to the agreement) can modify the order price. If the order prices modified by both parties are inconsistent, the settlement payment end will be marked in red. When the reconciliation cycle is opened (such as the 20th of this month), the reconciliation process will be entered to confirm the reconciliation price of the corresponding order. When all order prices are consistent, they will be reviewed by auditors from both parties and a reconciliation statement will be generated after the review is passed.

[0108] Step S207, the settlement payment terminal receives the verification completion information sent by the purchasing entity terminal and the supply entity terminal, determines the payment amount, and sends a payment request to the purchasing entity terminal.

[0109] Specifically, after the verification is completed, the purchasing entity terminal and the supply entity terminal respectively send verification completion information to the settlement payment end, the settlement payment end receives the verification completion information from the purchasing entity terminal and the supply entity terminal, generates a statement of account, and the settlement payment end obtains the statement of account corresponding to the signed agreement, and obtains the payment ratio of the statement of account based on the signed agreement, and the settlement payment end determines the payment amount based on the payment ratio.

[0110] It should be understood that the statements generated during the reconciliation cycle are all statements that match the order time. It is necessary to find the statement corresponding to the signed agreement and determine the payment amount based on the statement payment ratio in the agreement parameters of the signed agreement.

[0111] Step S208: upon receiving the payment request, the purchasing entity terminal transfers the payment amount to the purchaser's supervision account according to the payment request.

[0112] In this embodiment, when the purchasing entity terminal receives the payment request sent by the settlement payment end, it calls the bank interface to transfer the payment amount to the purchaser's supervision account.

[0113] Step S209, upon receiving the settlement request sent by the supplier terminal, the settlement payment end notifies the purchaser's supervision account to pay the settlement amount to the supplier's supervision account according to the settlement request, and records the payment information, wherein the settlement amount is obtained based on the agreement prepaid amount and the payment amount.

[0114] Specifically, after the settlement payment end receives the settlement request, it enters the payment stage, and the payment method is one or more of cash, bank acceptance bills, commercial acceptance bills, accounts receivable, and accounts payable (it can be paid once or multiple times in different payment methods).

[0115] After the payment is completed, the purchaser calls the Bank-Enterprise Communication software to notify the bank terminal that the payment has been completed, and records the payment information and payment results through the settlement payment terminal. The Bank-Enterprise Communication is connected to the settlement payment terminal, bank terminal, purchasing entity terminal and supply entity terminal network.

[0116] This application realizes data interconnection through the settlement and payment end, realizes the traceability of the entire process of volume-based drug supply, use and settlement data, and can also manage payment accounts. At the same time, by connecting the settlement and payment end to the bank terminal, it can ensure timely repayment and payment security.

[0117] In some optional implementations of this embodiment, the settlement payment terminal sends the agreement to be signed to the subject terminal corresponding to the information of the agreement party for signing the agreement, and the steps of obtaining the signed agreement include:

[0118] The main terminal receives the agreement to be signed, and signs the agreement through the CA certificate to obtain the signed agreement.

[0119] CA certificates are issued by the CA Center (Certificate Authority Center). The CA Center is an authoritative, trustworthy, and impartial three-party identity authentication agency based on fingerprint recognition technology. It can confirm the true identity of the parties in electronic transactions and the authenticity and validity of the certificate information. Each party can go to the registration window of the CA Center in person to complete the registration procedures, or log in to the server of the CA Center through the main terminal network to register online.

[0120] When registering at the CA center, the parties to the agreement first set up their own unique CA center account, provide the party to the agreement's name, ID number, address, contact number and scanned copy of the ID document and other information, and the CA center verifies the authenticity and validity of each party's ID document and registration information. If the registrant is a company, group or institution, it is necessary to provide a business license and a copy and collect the fingerprint features of the legal representative and generate a fingerprint template. The CA center and the parties to the agreement both collect fingerprint images and extract fingerprint features from them through a fingerprint feature collection device. Among them, the fingerprint collection device includes a fingerprint sensor that collects fingerprint images. In this way, the parties to the agreement can collect fingerprint features through the fingerprint collection device and generate a fingerprint template as the registration password of the CA center.

[0121] This application completes the signing of the agreement through the CA certificate, which can improve the security and confidentiality of the signing process.

[0122] In some optional implementations, the steps of signing the agreement through the CA certificate to obtain the signed agreement include:

[0123] The main terminal sends the contract signing request to the CA center, and the CA center authenticates the agreement party based on the contract signing request;

[0124] After verification, the CA center generates a pair of public and private keys, uses the public key and the account corresponding to the agreement party to generate a CA certificate, and sends the account, private key and CA certificate to the corresponding subject terminal;

[0125] The subject terminal retrieves the private key to digitally sign the agreement to be signed, obtains the signed agreement, and transmits the signed agreement to the CA center;

[0126] The CA center decrypts the signed agreement using the public key to obtain the electronic signatures of each party to the agreement;

[0127] The CA center embeds the electronic signature into the signed agreement to obtain the signed agreement;

[0128] The CA center will send the signed agreement to each entity terminal.

[0129] In this embodiment, each party to the agreement collects a fingerprint image through a fingerprint feature collection device at the CA center or its own main terminal, extracts fingerprint features from it, and compares it with the fingerprint features at the time of registration. If the similarity between the two exceeds a predetermined threshold, the identity authentication of the party to the agreement is passed.

[0130] In this embodiment, the CA certificate is a digital certificate. The CA center includes a password generator that generates a pair of public and private keys through the RSA algorithm. The CA center generates a digital certificate using the public key and account number through the algorithm. The CA center issues a physical storage medium storing the respective private keys and digital certificates to each party to the agreement. The physical storage medium can be a USB flash drive or an SD card.

[0131] The private key and digital certificate can also be obtained by the parties to the agreement logging into the CA center server network through the main terminal to download, or the private key and digital certificate of the parties to the agreement can be encrypted by the DES algorithm and stored in different USB Key devices and issued to the parties to the agreement accordingly.

[0132] After obtaining the private key and digital certificate, the parties to the agreement store them in the corresponding main terminal of the parties to the agreement, retrieve the private key to digitally sign the agreement to be signed, and transmit the signed agreement obtained after signing to the CA center through electronic information exchange at the main terminals of the parties to the agreement.

[0133] It should be noted that all parties to the agreement must undergo identity authentication at their respective principal terminals. Only after verification can they digitally sign the agreement to ensure that the executors of the electronic agreement are the legitimate parties to the agreement, effectively preventing others from exceeding their authority or impersonating others to sign the electronic agreement.

[0134] In this embodiment, the signed agreement with the digital signatures of the parties to the agreement can be sent to the corresponding principal terminals of the parties to the agreement through the server network or email, etc. After the parties to the agreement use fingerprint verification to confirm their legal identities at the principal terminal, they can obtain the signed agreement with the digital signatures of the parties to the agreement.

[0136] The settlement payment terminal generates a payment instruction based on the settlement request and sends the payment instruction to the bank terminal;

[0137] When receiving the payment instruction, the bank terminal pays the settlement amount from the purchaser's escrow account to the supplier's escrow account according to the payment instruction.

[0138] The payment behavior occurs at the bank terminal, and the settlement payment end is the instruction issuer. Only when the bank terminal receives the payment instruction issued by the settlement payment end (such as payee, payee, payment amount, etc.) can the payment behavior be completed. In this way, the management of the payment account can be realized.

[0139] In some optional implementations, upon receiving the payment instruction, the step of the bank terminal paying the settlement amount from the purchaser's escrow account to the supplier's escrow account according to the payment instruction includes:
