Description

Technical Field

[0001] The present disclosure relates to a verification system (device) and a checking method for ensuring the secure distribution of at least one piece of patient information and / or location information to a medical device and checking the distribution. Background of the Invention

[0003] In clinical practice, medical devices are connected to patients. Both the medical device and the patient are identified using a "reader," and the data packets read out during this process are sent to a server. The read data specifically includes patient information and / or location information assigned to at least one medical device. The location information preferably includes information about the patient's bed or room, as well as the location of medical devices located primarily in the room or near the patient's bed.

[0004] Data transfer is provided between a server and at least one medical device (such as one or more infusion pumps). Here, the medical device may receive, for example, a prescription and / or medication for a specific patient. In this data transfer, it is important that the data received by the medical device reaches the correct patient.

[0005] Methods for logically assigning medical products to patients are known. These are used, for example, for the automated programming of infusion pumps. Current implementations of logically assigning medical products to patients do not solely adhere to the error-proofing requirements of the IEC 60601-1 standard. In clinical practice, this means that assignment information is not fully reliable and requires additional user verification. For example, the therapy sequence sent to an infusion pump must be verified and confirmed by the user before the infusion begins. Existing technology

[0006] According to current existing technology, the server knows which patient ID belongs to a specific medical product. Although the server can forward this patient ID information to the medical product, this process is not fail-safe. Errors that may occur in previous systems cannot be detected according to this existing technology and may lead to incorrect routing.

[0007] In other words, current implementations allow medical products to be assigned to patients only logically. However, no confirmation or verification of this assignment is provided. Furthermore, disadvantageously, the location of the patient's bed, such as the room or ID, is not covered. Summary of the Invention

[0008] The present invention is therefore based on the object of developing a verification system for assigning at least one medical device to a patient, which avoids or at least reduces the disadvantages of the prior art.

[0009] The core of the present invention is to provide a verification system, which includes: at least one medical device; an identification device; and a server, the server communicating with the at least one medical device and the identification device, and the server being provided and configured to assign the at least one medical device to a corresponding patient and / or patient bed or respectively patient information and / or location information according to an assignment process. The at least one medical device is connected or respectively connectable to a patient, and both the medical device and the patient have or can respectively have at least one identification mark. The identification device is provided with a display and is designed and configured to read the identification mark.

[0010] According to the present invention, a review device is further arranged, which is provided and configured to review the allocation of at least one medical device to the corresponding patient and / or patient bed or the corresponding patient information and / or location information respectively via a first transaction ID generated by the server in a review process independent of / separate from the allocation process.

[0011] In other words, this means that the patient and / or patient bed and at least one medical device each have an identification tag, which is read by the identification device according to the allocation process. The data read from the identification tags of the patient and / or patient bed and at least one corresponding medical device is sent as a data packet to the server. During the review process, a first transaction ID is then generated based on the data packet received from the server. The generated first transaction ID enables review of the allocation of the at least one medical device to the corresponding patient and / or patient bed, or respectively, to the patient information and / or location.

[0012] The above-described authentication system provides a basis for a medical server application that uses data from multiple medical devices / medical products that are linked / connected to a single patient and / or location.

[0013] It is also preferred if the identification device is designed as a connection device, and the verification system establishes a connection between the server or server address and the medical device and / or patient and / or patient bed and / or connected system in order to securely assign data transmitted from the medical device to the server to the patient and / or patient bed. This enables the user, in particular the doctor, to make a diagnosis and / or adjust the treatment. In particular, it is also preferred if the connection between the server or server address and the medical device and / or patient and / or patient bed is established and used via remote control. It is also preferred if the identification device reads the identification mark optically (e.g., using infrared light). This offers the advantage that the user / operator of the identification device can be at a variable distance and / or angle from the identification mark.

[0014] This makes it possible to dynamically and securely logically assign and link medical products to patient information and / or location information. This assumes that the patient information and / or location information is included in the technical or medical data reported by at least one medical device / medical product, and enables data from multiple medical devices / medical products to be linked / assigned to a patient and / or location. Thus, any data received from a medical product (such as a therapy prescription for a specific patient) can be securely reviewed to ensure it is sent to the correct medical device connected to the correct patient and / or location.

[0015] Advantageous embodiments are claimed in the dependent claims and are explained in more detail below.

[0016] It is preferred if the identification mark is configured as a QR code, a barcode, or an identification number and includes at least a device ID, a patient ID, and / or a location ID. In other words, this means that the patient wears, for example, a wristband with a corresponding identification mark, which includes the patient ID. Alternatively or additionally, it is also provided that the patient bed includes an identification mark that outputs a location ID, preferably the ID of the patient bed and / or the associated room. The identification mark is also attached to at least one medical device, which outputs the device ID. This has the advantage that the identification mark can be easily read out by the identification device. The identification device is preferably designed as a QR code reader and / or a barcode reader, or alternatively as an optical camera system.

[0017] Preferably, the server-generated first transaction ID consists of a device ID, a patient ID, and / or a location ID. Healthcare organizations maintain a list of unique identification elements for medical products, medical devices, patients, and / or locations. This could be, for example, a patient wristband with a unique identification number or QR code containing information identifying the medical product / medical device or location information.

[0018] It is preferred that, during the review process, the medical device be provided and configured to receive the first transaction ID and transmit a modified second transaction ID to the server if the first transaction ID includes a device ID. In other words, the server transmits the generated first transaction ID to the at least one medical device. The at least one medical device then checks whether the first transaction ID includes a device ID corresponding to the at least one medical device. If so, the at least one medical device displays the changed / modified second transaction ID on the screen of the identification device.

[0019] It is preferred if during the review process a server is provided and configured to compare the received second transaction ID with the generated first transaction ID stored on the server. In other words, this means that the second transaction ID is sent back from the identification device to the server. The server compares the second transaction ID with the first transaction ID, which is stored on the server.

[0020] It is preferred if, in the event of a positive comparison among the medical devices, an identification device is provided during the review process and is configured to visualize the positive assignment of the medical device to the patient and / or location on a display, preferably using an optical symbol. This means that the assignment of at least one medical device to the patient and / or location is considered valid if the first transaction ID matches the second transaction ID. The valid connection / assignment of at least one medical device / product to the patient and / or patient bed, or respectively to the patient information and / or location information, is ultimately visualized by the optical symbol assigned to the identification device.

[0021] It is preferred if during the review process the server is provided and configured to change the second transaction ID to a third transaction ID and send it to the medical device. In other words, the second transaction ID received by the server is modified again and sent to at least one medical device.

[0022] It is preferred if during the review process the medical device is provided and configured to compare the received third transaction ID with the stored second transaction ID. The at least one medical device compares this modified third transaction ID with the second transaction ID stored in the at least one medical device.

[0023] It is preferred if, in the event of a positive comparison, an identification device is provided during the review process and is configured to visualize the positive assignment of the at least one medical device to the patient and / or location on a display, preferably using an optical symbol. This means that if the second transaction ID matches the third transaction ID, the assignment of the at least one medical device to the patient and / or patient bed, or respectively to the patient information and / or location information, is deemed valid. The valid connection / assignment of the at least one medical device / product to the patient and / or location is ultimately visualized by an optical symbol on the screen of the identification device.

[0024] It is preferred if the verification system is provided and configured to group patient information and / or location information from multiple medical devices / medical products associated with a single patient or location. In other words, this means that at this point in time, all data sent by the at least one medical device contains / includes patient information and / or location information that allows combining data from multiple medical devices / medical products. Furthermore, the at least one medical device is configured / capable of performing independent verification of the incoming control sequence.

[0025] In summary, the verification system enables auditing of allocations made during the allocation process. Thus, with the aid of auditing devices, this audit provides a means for preventing individual errors independent of the allocation process. The verification system thus offers the advantage of error-proofing the allocation of data from medical products / medical devices to patient IDs and / or location IDs. Furthermore, through the audit process, this data can be used in server applications for therapy decisions, grouping data from a large number of medical products / medical devices belonging to a single patient / location, and accepting control data for remotely controlled medical products / medical devices.

[0026] Furthermore, the invention relates to a checking method for ensuring the assignment of at least one piece of patient information and / or location information to at least one medical device and for reviewing said assignment, comprising the following steps.

[0027] In a first step, the identification identifier is read and the device ID, patient ID, and / or location ID are output as a data packet by the identification device. In a second step, this read data is sent as a data packet to a server. The server generates a first transaction ID based on the device ID, patient ID, and / or location ID and sends the generated first transaction ID to at least one medical device. In a further step, if the first transaction ID contains a device ID, the first transaction ID is changed / modified to a second transaction ID. This means that at least one medical device checks whether its device ID is included in the first transaction ID. If so, the first transaction ID is modified and displayed on the display of the identification device.

[0028] In a subsequent step, the second transaction ID is sent back to the server and compared with the first transaction ID stored in the server. If the comparison matches, an optical symbol is visualized on the display of the recognition device and the second transaction ID is changed to a third transaction ID in the server.

[0029] The third transaction ID is sent to at least one medical device and the received third transaction ID is compared with the stored second transaction ID. In a final step, if the comparison matches, the optical symbol is visualized and displayed on the screen of the identification device.

[0030] After successful execution of the above steps, the logical linking / assignment of the medical product / medical device to the patient and / or location is verified both on the server side and on the medical device side.

[0031] By repeating this method, multiple / different medical devices / medical products (such as multiple infusion pumps, dialysis machines, ventilators, physiological sensors, etc.) can be associated with or assigned to a single patient and / or location.

[0032] The present invention provides for data transfer between medical devices (e.g., two medical devices, namely, pump 1 and pump 2) and an application communicating with each other via a server. During certain short interruptions / pauses in the method, the system continues to operate, and during longer interruptions / pauses, the dispensing process is initiated again. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Figure 1 is a schematic representation illustrating a verification system and an inspection method according to an embodiment of the present disclosure. DETAILED DESCRIPTION

[0034] The preferred embodiments of the present disclosure are described below based on the accompanying drawings. The accompanying drawings are merely schematic in nature and are provided for the purpose of understanding the present invention. The same elements are designated by the same reference numerals.

[0035] Figure 1 is a representation showing an authentication system 1 according to an embodiment of the present disclosure. Figure 1 The arrows marked S10 to S15 shown represent communication links / data paths, which are referred to as steps S10 to S15 in the following description. Figure 1 The verification system 1 further comprises a medical device 2. The medical device 2 is Figure 1 In the example of a plurality of infusion pumps, the medical device 2 and the depicted patient (patient arm) 3 or respectively the depicted patient bed 11 each have an identification mark 4 in the form of a QR code as a further part of the authentication system 1. During operation, the medical device 2 is connected to the patient 3 (not shown) or is located near the patient bed.

[0036] Furthermore, the verification system 1 has an identification device 5. The identification device 5 is configured to read identification marks 4 from the medical device 2 and the patient 3 and / or the patient bed 11. The identification device 5 reads the device ID, the patient ID, and / or the location ID / patient bed ID from the identification marks 4. The identification device 5 has a display 6 configured to display / visualize information and / or symbols.

[0037] Figure 1 Also shown is a server 7 that communicates with both the medical device 2 and the identification device 5 .

[0038] According to the allocation process, the identification device 5 reads the identification marks 4 of the medical device 2 and the patient 3 and / or the patient bed according to step S10. In step S11, the read device ID, patient ID and / or location ID are transmitted / sent as a data packet to the server 7.

[0039] Subsequent steps are performed according to the review process. Here, in step S12, server 7 generates a first transaction ID based on the received device ID, patient ID, and / or location ID, and sends the first transaction ID to medical device 2. Medical device 2 checks whether the device ID corresponding to medical device 2 is included in the received first transaction ID.

[0040] If this is the case, the display of the medical device 2 shows the modified second transaction ID according to step S13. The modification ensures that the transaction ID is routed through the medical device 2. This modified second transaction ID is read in by the identification device 5.

[0041] In step S14, the second transaction ID is sent back to the server 7 and compared with the first transaction ID stored in the server 7. In the event of a positive comparison of the second transaction ID with the first transaction ID, the identification device 5 is adapted to visualize a positive assignment of the medical device 2 to the patient 3 and / or the patient bed 11 based on the position represented by the optical symbol on the display 6 and designate the assignment as valid.

[0042] In step S15, the server 7 modifies the second transaction ID into a third transaction ID and sends the third transaction ID to the medical device 2. The medical device 2 compares the received third transaction ID with the stored second transaction ID. In the event of a positive comparison of the third transaction ID with the second transaction ID, the identification device 5 is configured to visualize a positive assignment of the medical device 2 to the patient 3 and / or the patient bed 11 based on the location using a visual symbol on the screen / display of the medical device 2 and designate the assignment as valid.

[0043] Furthermore, it is preferred if in a further step S16 a positive assignment or verification is additionally displayed on the display of the identification device 5. This information about the positive verification is reported back to the user / operator by the identification device 5, for example optically, acoustically or haptically / vibrationally.

[0044] After executing the aforementioned steps S10 to S15 or S16 respectively, all data sent from the medical device / product 2 includes patient information and / or location information allowing combining multiple medical devices 2, and the medical device 2 is also provided for independent verification of the incoming examination order.

[0045] In particular, it is assumed that the allocation process can be performed independently of the review process.
