[0002] Medical devices are crucial medical consumables in hospital management systems. Due to the high safety requirements of medical consumables, it is essential for hospital management systems to monitor the real-time inventory and usage status of various medical consumables. Currently, to improve user experience and medical efficiency, an online purchasing platform is provided. Users can access the online platform by scanning a QR code at the bedside. This online platform is connected to the hospital management system and synchronized with the warehousing center. Therefore, the technical problem this invention aims to solve is how to trace the source of medical devices purchased by users through the online purchasing platform. Summary of the Invention

[0003] The purpose of this invention is to provide a medical device traceability method and system based on bedside QR codes. This method links medical device information submitted by users through an online purchasing platform with medical record information submitted through a hospital management system. Based on this association, the online purchasing platform provides users with targeted verification methods. After the user completes the verification, the traceability information of the medical device purchased by the user is automatically obtained. This provides a better user experience while ensuring the accuracy of medical device traceability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0005] A method for tracing medical devices based on bedside QR codes involves placing a QR code generated by a medical device transaction terminal next to each bed, with each QR code associated with a corresponding bed number to form a traceability location group. The method includes the following steps:

[0006] S1. When a patient's request for admission is received, the patient's identity information, bed number, and current medical record are extracted. The source location group is then associated with the current medical record based on the bed number.

[0007] S2. When a medical device transaction request is received from the current user by scanning the QR code next to the current bedside, the current medical device information of the current user is being traded is extracted.

[0008] S3. Obtain a pre-built medical device type table, in which all medical devices are classified into general-purpose and special-purpose types. Based on the medical device type table, determine and analyze the types of medical devices in the current medical device information. If the current medical device information only contains general-purpose types, proceed to step S4; if the current medical device information contains special-purpose types, proceed to step S5.

[0009] S4. Obtain the patient's identity information associated with the bed number through the current bedside QR code, generate a first verification based on the patient's identity information and send it to the current user, and obtain the traceability information of the medical device in the current medical device information based on the current user's response to the first verification.

[0010] S5. Obtain the current medical record of the patient associated with the bed number through the current bedside QR code, determine whether the current medical record matches the special type of medical device in the current medical device information, and obtain the traceability information of the medical device in the current medical device information based on the matching result.

[0011] A further preferred technical solution is as follows: the process of constructing the medical device type table is as follows:

[0012] Obtain the instruction manuals for all medical devices, analyze them to determine the target population for each device, and classify the device as a general-purpose device if it is suitable for a broad population; classify it as a special-purpose device if it is suitable for a specific population.

[0013] Based on the determination structure, all types of medical devices are obtained, and a medical device type table is constructed.

[0014] The term "broad population" indicates that the medical records of the population to whom the medical device is applicable do not contain specific medical characteristics.

[0015] The term "specific population" refers to the medical records of the target population for this medical device that exhibit specific medical characteristics.

[0016] The medical features include disease diagnosis data, medication data, and test indicator data.

[0017] A further preferred technical solution is as follows: In S4, the process of generating a first verification based on the patient's identity information and sending it to the current user is as follows: The patient's identity information associated with the bed number is obtained through the current bedside QR code. The identity information includes the patient's name and contact information. A first verification is generated based on the patient's name and contact information. The current user responds to the first verification by comparing the patient's name and contact information entered by the user with the patient's name and contact information in the identity information. If the information is entered correctly, the response result is that the user has passed the first verification; if the information is entered incorrectly, the response result is that the user has failed the first verification.

[0018] A further preferred technical solution is as follows: In S4, the process of obtaining the traceability information of the medical device in the current medical device information based on the current user's response to the first verification includes the following steps:

[0019] SA1. Obtain the current user's response to the first verification. If the response indicates that the user has passed the first verification, proceed to step SA2; if the response indicates that the user has failed the first verification, proceed to step SA3.

[0020] SA2. Obtain the traceability location group through the current bedside QR code, and generate the traceability information of the medical device in the current medical device information based on the patient's identity information and the traceability location group.

[0021] SA3. Obtain the current user's identity information and generate the traceability information of the medical device in the current medical device information based on the user's identity information.

[0022] A further preferred technical solution is as follows: In S5, the process of determining whether the current medical record matches the special-type medical device in the current medical device information is as follows:

[0023] First, the preset matching rules for the special-purpose medical device in the current medical device information are called; then, the current medical record of the patient associated with the bed number is extracted to obtain the disease diagnosis data, medication data, and test index data in the current medical record, with the priority of the disease diagnosis data, medication data, and test index data decreasing in that order.

[0024] According to the preset matching rules and priorities, the disease diagnosis data, medication data, and test indicator data in the current medical record are verified in turn to see if they meet the conditions. When the disease diagnosis data meets the conditions, but the medication data or test indicator data does not meet the conditions, it is determined that the current medical record is successfully matched with the special type of medical device in the current medical device information, and so on.

[0025] A further preferred technical solution is as follows: The process of obtaining the traceability information of medical devices in the current medical device information based on the matching results includes the following steps:

[0026] SB1. Obtain the matching result of the current medical record and the special type of medical device in the current medical device information. If the matching result is successful, proceed to step SB2; if the matching result is unsuccessful, proceed to step SB3.

[0027] SB2. Obtain the traceability location group through the current bedside QR code, and generate the traceability information of the medical device in the current medical device information based on the patient's identity information and the traceability location group;

[0028] SB3. Obtain the traceability location group through the current bedside QR code. Generate a second verification based on the current medical device information of the current user's transaction and the traceability location group, and send it to the current user. Obtain the traceability information of the medical device in the current medical device information based on the current user's response to the second verification.

[0029] A further preferred technical solution is as follows: In SB3, a second verification is generated based on the current medical device information and the traceability location group of the current user's transaction and sent to the current user. The current user responds to the second verification and confirms the traceability location group corresponding to the current medical device information. If the confirmation is incorrect, the correct traceability location group is filled in, and the response result is that the user has not passed the second verification; if the confirmation is correct, the response result is that the user has passed the second verification.

[0030] A further preferred technical solution is as follows: The process of obtaining the traceability information of the medical device in the current medical device information based on the current user's response to the second verification is as follows:

[0031] The system retrieves the user's response to the second verification. If the response indicates that the user has passed the second verification, the system updates the current medical record based on the specific medical device in the current medical device information and generates the traceability information of the medical device in the current medical device information using the patient's identity information and traceability location group. If the response indicates that the user has failed the second verification, the system retrieves the correct traceability location group and identity information entered by the user and generates the traceability information of the medical device in the current medical device information using the correct traceability location group entered by the user.

[0032] A medical device traceability system based on bedside QR codes, employing the aforementioned medical device traceability method based on bedside QR codes, includes:

[0033] Data preprocessing module: When receiving a patient's admission request, extracts the patient's identity information, bed number, and current medical record, and associates the traceability location group with the current medical record based on the bed number;

[0034] Medical device transaction module: When it receives a medical device transaction request submitted by the current user by scanning the QR code next to the current hospital bed, it extracts the current medical device information of the current user's transaction.

[0035] The medical device type analysis module obtains a pre-built medical device type table, which categorizes all medical devices into general-purpose and special-purpose types. Based on the medical device type table, the module determines and analyzes the type of medical devices in the current medical device information.

[0036] First traceability information generation module: Obtain the patient's identity information associated with the bed number through the current bedside QR code, generate the first verification based on the patient's identity information and send it to the current user, and obtain the traceability information of the medical device in the current medical device information based on the current user's response to the first verification.

[0037] The second traceability information generation module obtains the current medical record of the patient associated with the bed number through the current bedside QR code, determines whether the current medical record matches the special type of medical device in the current medical device information, and obtains the traceability information of the medical device in the current medical device information based on the matching result.

[0038] The beneficial effects of this invention are:

[0039] This invention provides a method and system for tracing medical devices based on bedside QR codes. The system traces medical devices through an online purchasing platform, where users can scan a bedside QR code to select and purchase the desired goods online. These goods primarily refer to medical devices that users can purchase themselves. By using an online purchasing platform, the original single purchasing model is changed, thereby improving the user experience.

[0040] For online purchasing platforms, this invention connects them with hospital management systems, enabling the system to associate medical device information submitted by users through the online purchasing platform with medical record information submitted through the hospital management system. Through this association, information such as the inventory status and usage status of medical devices can be obtained.

[0041] Based on the above-mentioned relationship, targeted verification methods are proposed for users through online purchasing platforms. After the user completes the verification, the traceability information of the medical devices purchased by the user is automatically obtained, which not only improves the user experience but also ensures the accuracy of medical device traceability.

[0042] Figure 1 This is a schematic diagram of the online purchasing platform in Embodiment 1 of the present invention.

[0043] Figure 2 This is a flowchart illustrating the medical device traceability method in Embodiment 1 of the present invention. Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0045] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of the invention.

[0046] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0047] Furthermore, for clarity and brevity, descriptions of well-known structures, functions, and configurations may have been omitted.

[0048] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0049] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0050] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0051] Example 1

[0052] To improve user experience and medical efficiency, an online purchasing platform is provided, such as... Figure 1 As shown, the online purchasing platform refers to the ability for users to select and purchase necessary goods online by scanning a QR code next to the hospital bed. These goods mainly refer to medical devices that users can purchase themselves, such as sterile gauze, bandages, medical cotton swabs, medical ice packs, waist supports, and knee supports. After purchasing, the goods can be delivered by service personnel or picked up by the user from a vending machine, changing the original single purchasing model and improving the user experience.

[0053] Since medical devices are important medical consumables in hospital management systems, and some medical consumables have high safety requirements, such as insulin pens and nebulizers, it is very important for hospital management systems to understand the real-time inventory and usage status of various medical consumables in the hospital.

[0054] Therefore, in this embodiment, medical device traceability is performed based on an online purchasing platform. First, the online purchasing platform is connected to the hospital management system. Then, QR codes generated by medical device transaction terminals are placed next to all hospital beds, and these QR codes are associated with the corresponding bed numbers to form traceability location groups. These traceability location groups are used to associate the medical device information submitted by the user through the online purchasing platform with the medical record information submitted through the hospital management system. Based on the above association, a targeted verification method is provided to the user on the online purchasing platform. After the user completes the verification, the traceability information of the medical device purchased by the user is automatically obtained. This approach provides a better user experience while ensuring the accuracy of medical device traceability.

[0055] Based on the above principles, a medical device traceability method based on bedside QR codes is proposed, such as... Figure 2 As shown, the medical device traceability method includes the following:

[0056] S1. When a patient's request for admission is received, the patient's identity information, bed number, and current medical record are extracted. The source location group is then associated with the current medical record based on the bed number.

[0057] S2. When a medical device transaction request is received from the current user by scanning the QR code next to the current bedside, the current medical device information of the current user is being traded is extracted.

[0058] S3. Obtain a pre-built medical device type table, in which all medical devices are classified into general-purpose and special-purpose types. Based on the medical device type table, determine and analyze the types of medical devices in the current medical device information. If the current medical device information only contains general-purpose types, proceed to step S4; if the current medical device information contains special-purpose types, proceed to step S5.

[0059] S4. Obtain the patient's identity information associated with the bed number through the current bedside QR code, generate a first verification based on the patient's identity information and send it to the current user, and obtain the traceability information of the medical device in the current medical device information based on the current user's response to the first verification.

[0060] S5. Obtain the current medical record of the patient associated with the bed number through the current bedside QR code, determine whether the current medical record matches the special type of medical device in the current medical device information, and obtain the traceability information of the medical device in the current medical device information based on the matching result.

[0061] A further preferred technical solution is as follows: the process of constructing the medical device type table is as follows:

[0062] Obtain the instruction manuals for all medical devices, analyze them to determine the target population for each device, and classify the device as a general-purpose device if it is suitable for a broad population; classify it as a special-purpose device if it is suitable for a specific population.

[0063] Based on the determination structure, all types of medical devices are obtained, and a medical device type table is constructed.

[0064] The term "broad population" indicates that the medical records of the population to whom the medical device is applicable do not contain specific medical characteristics.

[0065] The term "specific population" refers to the medical records of the target population for this medical device that exhibit specific medical characteristics.

[0066] The medical features include disease diagnosis data, medication data, and test indicator data.

[0067] Specifically, the medical devices include sterile gauze, adhesive bandages, medical cotton swabs, medical ice packs, lumbar supports, knee braces, insulin pens, nebulizers, blood glucose test strips, etc., all of which can be purchased by the user. Based on the instruction manuals of the medical devices and the user's historical medical records in the hospital management system, the correlation between the medical devices and medical characteristics can be determined. For example, the instruction manual for an insulin pen states that the device is suitable for a specific population. The historical medical records of diabetic patients show specific medical characteristics: the disease diagnosis data records that the user has diabetes, the medication data records that the user has been using insulin for a long time, and the test indicator data records that the user's blood glucose exceeds the threshold. Therefore, it can be determined that the insulin pen is suitable for a specific population, namely diabetic patients.

[0068] The list of medical device types is shown in Table 1 below:

[0069]

[0070] In summary, by analyzing the instruction manuals for medical devices and the historical medical records of users in the hospital management system, all medical devices offered by online purchasing platforms can be pre-classified into general-purpose and specialized types. Specifically, general-purpose medical devices include sterile gauze, adhesive bandages, medical cotton swabs, medical ice packs, lumbar supports, and knee braces, etc., applicable to a broad population; therefore, users do not need specific disease diagnosis data, medication data, or test result data. Specialized medical devices, on the other hand, include insulin pens, nebulizers, and blood glucose test strips, applicable to specific populations; therefore, users need specific disease diagnosis data, medication data, and test result data. For example, if a user's disease diagnosis data records diabetes, their medication data records long-term insulin use, and their test result data records blood glucose exceeding a threshold, it indicates that the user is a diabetic patient with specific medical characteristics. By matching the user's medical records with the medical devices, the user and the type of medical device can be matched, thus classifying the medical devices into general-purpose and specialized types.

[0071] The medical characteristics include disease diagnosis data, medication data, and test indicator data. When any one of the disease diagnosis data, medication data, or test indicator data meets the condition, that is, the user's medication data records that the user has been using insulin for a long time, it can be said that the user has a specific medical characteristic.

[0072] A further preferred technical solution is as follows: In S4, the process of generating a first verification based on the patient's identity information and sending it to the current user is as follows: The patient's identity information associated with the bed number is obtained through the current bedside QR code. The identity information includes the patient's name and contact information. A first verification is generated based on the patient's name and contact information. The current user responds to the first verification by comparing the patient's name and contact information entered by the user with the patient's name and contact information in the identity information. If the information is entered correctly, the response result is that the user has passed the first verification; if the information is entered incorrectly, the response result is that the user has failed the first verification.

[0073] A further preferred technical solution is as follows: In S4, the process of obtaining the traceability information of the medical device in the current medical device information based on the current user's response to the first verification includes the following steps:

[0074] SA1. Obtain the current user's response to the first verification. If the response indicates that the user has passed the first verification, proceed to step SA2; if the response indicates that the user has failed the first verification, proceed to step SA3.

[0075] SA2. Obtain the traceability location group through the current bedside QR code, and generate the traceability information of the medical device in the current medical device information based on the patient's identity information and the traceability location group.

[0076] SA3. Obtain the current user's identity information and generate the traceability information of the medical device in the current medical device information based on the user's identity information.

[0077] A further preferred technical solution is as follows: In S5, the process of determining whether the current medical record matches the special-type medical device in the current medical device information is as follows:

[0078] First, the preset matching rules for the special-purpose medical device in the current medical device information are called; then, the current medical record of the patient associated with the bed number is extracted to obtain the disease diagnosis data, medication data, and test index data in the current medical record, with the priority of the disease diagnosis data, medication data, and test index data decreasing in that order.

[0079] According to the preset matching rules and priorities, the disease diagnosis data, medication data, and test indicator data in the current medical record are verified in turn to see if they meet the conditions. When the disease diagnosis data meets the conditions, but the medication data or test indicator data does not meet the conditions, it is determined that the current medical record is successfully matched with the special type of medical device in the current medical device information, and so on.

[0080] A further preferred technical solution is as follows: The process of obtaining the traceability information of medical devices in the current medical device information based on the matching results includes the following steps:

[0081] SB1. Obtain the matching result of the current medical record and the special type of medical device in the current medical device information. If the matching result is successful, proceed to step SB2; if the matching result is unsuccessful, proceed to step SB3.

[0082] SB2. Obtain the traceability location group through the current bedside QR code, and generate the traceability information of the medical device in the current medical device information based on the patient's identity information and the traceability location group;

[0083] SB3. Obtain the traceability location group through the current bedside QR code. Generate a second verification based on the current medical device information of the current user's transaction and the traceability location group, and send it to the current user. Obtain the traceability information of the medical device in the current medical device information based on the current user's response to the second verification.

[0084] A further preferred technical solution is as follows: In SB3, a second verification is generated based on the current medical device information and the traceability location group of the current user's transaction and sent to the current user. The current user responds to the second verification and confirms the traceability location group corresponding to the current medical device information. If the confirmation is incorrect, the correct traceability location group is filled in, and the response result is that the user has not passed the second verification; if the confirmation is correct, the response result is that the user has passed the second verification.

[0085] A further preferred technical solution is as follows: The process of obtaining the traceability information of the medical device in the current medical device information based on the current user's response to the second verification is as follows:

[0086] The system retrieves the user's response to the second verification. If the response indicates that the user has passed the second verification, the system updates the current medical record based on the specific medical device in the current medical device information and generates the traceability information of the medical device in the current medical device information using the patient's identity information and traceability location group. If the response indicates that the user has failed the second verification, the system retrieves the correct traceability location group and identity information entered by the user and generates the traceability information of the medical device in the current medical device information using the correct traceability location group entered by the user.

A method for tracing medical devices based on bedside QR codes according to claim 5, characterized in that, The process of obtaining the traceability information of the medical device in the current medical device information based on the current user's response to the second verification is as follows: The system retrieves the user's response to the second verification. If the response indicates that the user has passed the second verification, the system updates the current medical record based on the specific medical device in the current medical device information and generates the traceability information of the medical device in the current medical device information using the patient's identity information and traceability location group. If the response indicates that the user has failed the second verification, the system retrieves the correct traceability location group and identity information entered by the user and generates the traceability information of the medical device in the current medical device information using the correct traceability location group entered by the user.

8. A medical device traceability system based on bedside QR codes, characterized in that, The method for tracing medical devices based on bedside QR codes as described in any one of claims 1-7 includes: Data preprocessing module: When receiving a patient's admission request, extracts the patient's identity information, bed number, and current medical record, and associates the traceability location group with the current medical record based on the bed number; Medical device transaction module: When it receives a medical device transaction request submitted by the current user by scanning the QR code next to the current hospital bed, it extracts the current medical device information of the current user's transaction. The medical device type analysis module obtains a pre-built medical device type table, which categorizes all medical devices into general-purpose and special-purpose types. Based on the medical device type table, the module determines and analyzes the type of medical devices in the current medical device information. First traceability information generation module: Obtain the patient's identity information associated with the bed number through the current bedside QR code, generate the first verification based on the patient's identity information and send it to the current user, and obtain the traceability information of the medical device in the current medical device information based on the current user's response to the first verification. The second traceability information generation module obtains the current medical record of the patient associated with the bed number through the current bedside QR code, determines whether the current medical record matches the special type of medical device in the current medical device information, and obtains the traceability information of the medical device in the current medical device information based on the matching result.
