Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a method for managing the use of an injection nozzle, a needle-free syringe, equipment and a medium. Background Art

[0002] Needle-free syringes are now widely used in the fields of diabetes treatment, medical cosmetology, vaccination, etc. They use the instantaneous high pressure generated by the power source to push the drug in the drug tube through the micropores to form high-speed, high-pressure drugs, so that the drugs can instantly penetrate the outer layer of the skin to the subcutaneous and intradermal tissue layers. This design can reduce the pain during the injection process, eliminate the fear of patients with needle phobia, improve patient compliance, and reduce allergic symptoms.

[0003] If the needle of a traditional needle syringe is reused during use, it may become a medium for spreading blood-borne diseases (such as HIV, hepatitis B, hepatitis C, etc.). Needle-free syringes reduce this risk by avoiding the use of needles, but if the nozzle is shared by multiple people, there is also the possibility of cross infection. Therefore, the injection nozzles of needle-free syringes are mostly disposable. For example, the Chinese invention patent with application publication number CN103432654A discloses a nozzle dedicated to needle-free syringes, which includes a nozzle body and an irregular spacer suitable for the nozzle. The nozzle body consists of a nozzle and a conical rear end portion, the conical rear end portion gradually narrows toward the small diameter nozzle, the irregular spacer is arranged on the nozzle and adapted to the nozzle, an annular groove is provided at the top of the conical rear end portion, and a stopper is provided on the inner wall of the annular groove. The stopper is destroyed after one use, thereby preventing secondary use and avoiding cross infection. For another example, the Chinese invention patent with application publication number CN106344205A discloses a needle-free high-speed jet syringe, whose nozzle is detachable to prevent cross infection, and adopts threaded connection to make assembly more convenient.

[0004] However, frequent replacement of nozzles requires high costs, which has led to some non-standard operating methods in the needle-free injection application industry, such as choosing to buy cheap imitation nozzles with unguaranteed quality. These counterfeit products often fail to meet the technical standards of the original nozzles and may cause a series of problems, including but not limited to poor injection dosage accuracy and uneven spraying. These problems will not only reduce the treatment effect, but may also pose a potential risk to the patient's health. For example, in order to save costs, some institutions fail to update the nozzles according to the recommended replacement cycle. This practice also poses serious safety hazards. Especially in medical environments, the irregular reuse or overuse of nozzles is very likely to make the nozzles a medium for the spread of pathogens, increase the probability of cross-infection, and may directly threaten the patient's life safety.

[0005] Therefore, in actual operation, the supervision of injection nozzles faces a severe dilemma, and the safety and effectiveness of injection are difficult to guarantee. Summary of the invention

[0010] In some embodiments, after generating the nozzle replacement reminder, it also includes: setting a second number threshold and a second duration threshold based on the preset nozzle usage limit; when the current number of injections exceeds the second number threshold and / or the current injection duration exceeds the second duration threshold, prohibiting needle-free injection operations.

[0011] In some embodiments, the method further includes: continuously verifying whether the valid code in the nozzle identity data has changed based on a preset interval; if the valid code has changed, it is determined that the nozzle has been replaced, the needle-free injection operation is prohibited, and S101 to S105 are re-executed.

[0012] In some embodiments, the S101 includes: receiving electronic coded data in a readable and writable chip of the nozzle; decoding the electronic coded data according to a preset decoding algorithm based on a decoder at the handpiece end to obtain the nozzle tracing data; or, receiving the electronic coded data in a readable and writable chip of the nozzle; sending the electronic coded data at the handpiece end to the cloud, so that the cloud decodes the electronic coded data to obtain the nozzle tracing data, and receiving the nozzle tracing data sent by the cloud to the handpiece end.

[0018] Furthermore, the minimum dosing interval is determined based on the current user's injection trauma recovery status, and then a lock period is set for the injection nozzle. During this period, the injection nozzle is locked and cannot be used, adaptively avoiding safety hazards caused by users illegally injecting excessive amounts during this period, or multiple users in a medical institution mixing injection nozzles.

[0019] Furthermore, after reminding the user to replace the nozzle according to the nozzle usage restriction, an appropriate usage threshold is reserved to provide preparation time for nozzle replacement while ensuring the injection effect. The operator can then flexibly control the timing of nozzle replacement according to actual scenarios such as the injection drug situation and user's vital signs, thereby improving the user experience of medical institutions and their operators.

[0020] Furthermore, the nozzle chip is continuously tested in situ to avoid the medical institution replacing the nozzle midway, thereby improving the effectiveness of injection nozzle supervision. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The safety of needle-free injections requires regular replacement of nozzles to reduce the risk of infection, but this practice puts medical institutions under high cost pressure. In the trade-off between safety and cost, medical institutions and their operators may tend to adopt non-standard operations. In order to ensure the safety and effectiveness of injections, strict regulatory measures need to be implemented. Therefore, it is necessary to find a balance between cost-effectiveness and operational convenience while ensuring safety.

[0032] The present invention comprehensively evaluates the compliance of nozzle usage from three dimensions: users, number of uses, and duration of use, providing highly reliable and strict supervision for the reuse of nozzles. Furthermore, it also takes into account the injection quality assessment of the nozzles during the reuse of nozzles, and refines the resource management of the nozzles after they are discarded to cover the entire life cycle of the nozzles. It flexibly takes into account high utilization and high injection effect, and provides a comprehensive supervision framework for the sustainable use of needle-free syringe nozzles.

[0033] In some embodiments, the present invention provides a highly reliable management method for the sustainable use of injection nozzles under strict supervision. Starting from the perspective of needle-free injection users at the two stages of nozzle replacement and nozzle use, the compliance of nozzle use is accurately assessed in three dimensions based on the number of uses and duration of use corresponding to the cumulative usage data, thereby providing a comprehensive regulatory framework for the sustainable use of needle-free syringe nozzles.

[0034] By tracing the nozzle data through the nozzle chip, it is possible to quickly track the legitimacy of the source and usage history of the nozzle, verify the compliance of needle-free injection users and cumulative usage information, and implement dynamic supervision to reasonably limit the overall usage threshold of the nozzle. Then, on the premise of making the best possible use of each injection nozzle, the reuse of injection nozzles is standardized to ensure the product qualification, usage compliance and injection safety of the nozzles. This not only ensures the safety and effectiveness of the injection, but also improves the utilization rate of the nozzle, alleviates the waste of resources and high costs, and promotes the healthy development of needle-free injection technology.

[0035] Specifically, the needle-free syringe includes a nozzle end and a handpiece end. The nozzle chip detects and obtains nozzle traceability data including nozzle identity data and nozzle usage data. The nozzle usage data includes cumulative usage data and expected user labels. Product matching verification and usage compliance verification are performed based on the nozzle traceability data. When the nozzle is qualified, there is no valid disabled label, and the user label is consistent, needle-free injection operation is allowed; the current usage data of the needle-free syringe is monitored, and the cumulative usage data is updated according to the current usage data; when the cumulative usage data exceeds the preset nozzle usage limit, the disabled label is written into the nozzle usage data, and the needle-free injection operation is prohibited.

[0036] See also Figure 1 , Figure 1 : is a schematic diagram of the structure of a needle-free syringe provided by an embodiment of the present invention, wherein the needle-free syringe comprises: A nozzle 1, used for spraying medicine, wherein the nozzle 1 is provided with a readable and writable chip 2 for storing nozzle traceability data; The hand tool 4 is used to store medicine and provide power for needle-free injection operation. The nozzle 1 is detachably connected to the hand tool 4 . The hand tool 4 is provided with a chip reader 3 for identifying the readable and writable chip 2 .

[0037] The controller is used to implement the steps of the method for managing the use of the injection nozzle provided in any embodiment of the present invention when performing a needle-free injection operation.

[0038] The read / write chip 2 has a data storage function and supports data reading and writing operations, so that the printhead traceability data stored in the read / write chip can be read, modified, and deleted to realize information flow. The read / write chip 2 can be a radio frequency identification chip, which is a wireless communication technology that can identify targets and read and write data through radio waves.

[0039] The hand tool 4 is connected to the controller via a data line 5, and the controller can communicate with the cloud.

[0040] See also Figure 2 , Figure 2 is a schematic flow chart of a method for managing the use of an injection nozzle provided by an exemplary embodiment of the present invention, such as Figure 2 As shown, the method is applied to a needle-free syringe, and the needle-free syringe includes a nozzle end and a hand tool end, including steps S101 to S105.

[0041] S101 obtains the nozzle traceability data of the nozzle based on the nozzle chip detection, wherein the nozzle traceability data includes the nozzle identity data and the nozzle usage data, and the nozzle usage data includes the accumulated usage data and the expected user tag.

[0042] Specifically, when the nozzle is installed on the handpiece, the chip reader in the handpiece detects the readable and writable chip in the nozzle, and the nozzle end and the handpiece end establish a communication connection through the readable and writable chip to obtain the nozzle traceability data stored in the readable and writable chip.

[0043] The nozzle identity data is data for verifying the authenticity and eligibility of the nozzle, such as the nozzle's valid code, specification model, injection dosage, nozzle's standard performance threshold and other product identity information. The nozzle usage data is data for recording the nozzle's usage history information, such as the nozzle's cumulative usage data, expected user label, injection drug label, etc.

[0044] In addition, the nozzle traceability data can also store data related to the nozzle, such as the manufacturer information, production batch number information, etc.

[0045] S102 performs product matching verification based on the nozzle identity data. If the nozzle identity data contains a valid code, the nozzle is determined to be a qualified product.

[0046] Specifically, the valid code is pre-written in the read-write chip of the qualified nozzle produced by the manufacturer. The valid code is used to verify whether the currently installed nozzle is a qualified product that matches the injection requirements, so as to distinguish between genuine products and imitations. After the nozzle is replaced, the nozzle data can be traced through the nozzle chip, which can quickly track the legitimacy of the source of the nozzle and ensure the product qualification of the nozzle, so as to ensure the safety and effect of the injection.

[0047] Exemplarily, the valid code can be encrypted information generated based on the unique identification of the nozzle, or it can be a valid code set based on a specific category of the nozzle. For example, the valid code for a nozzle with a single injection volume of 0.01 ml is different from the valid code for a nozzle with a single injection volume of 0.05 ml. Correspondingly, the handpiece end can also adjust the liquid discharge pattern according to the valid code, such as a 0.05 ml nozzle corresponds to a higher injection pressure.

[0048] In some embodiments, the S101 includes: receiving electronic coded data in a readable and writable chip of the nozzle; decoding the electronic coded data according to a preset decoding algorithm based on a decoder at the handpiece end to obtain the nozzle tracing data; or, receiving the electronic coded data in a readable and writable chip of the nozzle; sending the electronic coded data at the handpiece end to the cloud, so that the cloud decodes the electronic coded data to obtain the nozzle tracing data, and receiving the nozzle tracing data sent by the cloud to the handpiece end.

[0049] Specifically, in order to improve the accuracy of the nozzle traceability data and enhance the flexibility and reliability of the decoding of the electronic coded data, the embodiments of the present invention provide two decoding methods for the electronic coded data. First, the handpiece end is equipped with a decoder, which decodes the electronic coded data in the nozzle chip according to a pre-set decoding algorithm to obtain the nozzle traceability data. Second, when the handpiece end is not equipped with a decoder or the decoder fails to decode, the electronic coded data is transmitted to the cloud server, and the cloud server uses more powerful computing power to decode the electronic coded data, extract the nozzle traceability number, and then send the nozzle traceability data back to the handpiece end.

[0050] Correspondingly, when verifying the valid code of the needle-free syringe nozzle, the decoder built into the handpiece can directly apply a preset decoding algorithm to the received electronic code data, and then instantly verify the status of the nozzle through the valid code at the handpiece end to ensure the safety of each injection.

[0051] When more complex data processing or additional security verification is required, the handpiece can send the electronically coded data to the cloud server. The cloud server has more powerful computing resources and database support, can perform more complex algorithm decoding, and compare more data information to verify the valid code. After the cloud server completes the decoding and verification, it will feedback the results to the handpiece. Ensure that the nozzle of the needle-free syringe can be fully verified before each use, thereby ensuring the safety and effectiveness of the injection.

[0052] S103 detects whether there is a valid disabled tag in the nozzle usage data. If there is no valid disabled tag, obtains the expected user tag and the current user tag of the handpiece end; if the expected user tag is consistent with the current user tag, the needle-free injection operation is allowed by using compliance verification.

[0053] The expected user tag is a user identification tag generated based on historical usage or pre-set user information, which is used to restrict specific users from using the nozzle. Correspondingly, the current user tag on the handpiece is the user identification tag that is actually performing needle-free injection. The comparison of the two tags can ensure that only specific users can use specific nozzles, ensuring the safety of repeated use of needle-free injection nozzles. The user information can be user name, birthday, gender, address, etc., and can be one piece of information or a combination of multiple pieces of information.

[0054] Among them, the disabled tag is a tag used to restrict the continued use of the nozzle. It is generated because the nozzle has reached the preset nozzle usage limit, has a fault, or has expired. The presence of a disabled tag in the nozzle usage data means that the nozzle has an injection safety risk and can no longer be used.

[0055] Specifically, first check whether there is a valid disabled tag attached to the nozzle usage data to ensure that the nozzle is not disabled due to reaching the usage limit or other safety reasons. If there is no valid disabled tag, compare the expected user tag on the nozzle end and the current user tag on the handpiece end to ensure that the nozzle is only used by a specific user and prevent misuse and abuse of the nozzle. When the expected user tag matches the current user tag, it is confirmed that the usage is compliant and the needle-free injection operation is allowed.

[0056] It should be noted that if the nozzle is used for the first time and there is no pre-set user information, the expected user tag on the handpiece end and the current user tag on the handpiece end are both null values, and a user tag is generated according to the current user information on the handpiece end, and the user tag is written into the nozzle usage data as the expected user tag, and the user tag is stored in the handpiece end as the current user tag of the current user information. If a user purchases multiple nozzles for different drug uses, although the expected user tag of each nozzle is different, they point to the same specific user, that is, one user information may correspond to multiple user tags.

[0057] In some embodiments, the expected user tag is generated based on the user information and random data. The random data may be a timestamp of the first injection time, a password entered by the user, etc., so that the expected user tag of each spray head is unique.

[0058] This embodiment avoids misuse of nozzles due to the same user information, such as two users with the same name mistakenly using each other's nozzles, and also avoids misuse of nozzles for different purposes by the same user, for example, a user purchases multiple nozzles for different drug purposes, and different injected drugs obtain different current user tags. On the other hand, it also makes it difficult for a third party to imitate or forge the expected user tag based on user information, avoids intentional mixing of nozzles, and ensures the reliability of supervision of the use of needle-free injection nozzles.

[0059] It should be understood that the use of nozzle data traceability through nozzle chips can quickly track the use history of nozzles and verify the compliance of needle-free injection users and cumulative use information. Through a strict verification mechanism, it is ensured that each nozzle can work in its best condition, and the use of nozzles is personalized and targeted, effectively preventing the sharing of nozzles by multiple people, thereby making the reuse of needle-free injection nozzles safer and more reliable in clinical practice.

[0060] S104 monitors the current usage data of the needle-free injector, and updates the accumulated usage data according to the current usage data.

[0061] The cumulative usage data refers to the various operation data accumulated during the multiple uses of the needle-free injection nozzle, which is used to evaluate whether the nozzle is in a safe and effective state. The cumulative usage data may include the cumulative number of injections, the cumulative injection duration, the cumulative injection dose, the cumulative number of injection defects, etc.

[0062] Specifically, the control handpiece end obtains the initial first cumulative usage data in the readable and writable chip, and monitors the current usage data of the needle-free syringe, superimposes the current usage data on the first cumulative usage data at the handpiece end to obtain the second cumulative usage data, and writes the second cumulative usage data into the readable and writable chip to cover the first cumulative usage data to complete the update of the cumulative usage data.

[0063] In some embodiments, the cumulative usage data includes the cumulative number of injections and the cumulative injection duration, and the current usage data includes the current number of injections and the current injection duration; S104 includes: adding the current number of injections to the cumulative number of injections to update the cumulative usage data; and / or adding the current injection duration to the cumulative injection duration to update the cumulative usage data.

[0064] For example, when the initial cumulative number of injections in the readable and writable chip is 50 times and the cumulative injection time is 30 minutes, and the current number of injections of the needle-free injection nozzle is monitored to be 30 and the current injection time is 20 minutes, data superposition is performed on the handpiece end, and the cumulative number of injections is updated to 80 times and the cumulative injection time is 50 minutes, and the updated cumulative number of injections and cumulative injection time are written into the readable and writable chip to cover the initial cumulative number of injections and cumulative injection time.

[0065] S105: When the accumulated usage data exceeds the preset nozzle usage limit, the disable tag is written into the nozzle usage data, and the needle-free injection operation is prohibited.

[0066] The preset nozzle usage limit is flexibly set based on the performance of the needle-free injection nozzle and is not limited here. For example, from the perspective of the cumulative number of injections, the preset nozzle usage limit for a nozzle with a single injection volume of 0.01 ml may be 500 cumulative injections; the preset nozzle usage limit for a nozzle with a single injection volume of 0.05 ml may be 100 cumulative injections.

[0067] Specifically, when the accumulated usage data exceeds the preset nozzle usage limit, the nozzle has an injection safety risk or a risk of reduced injection effect and can no longer be reused. Therefore, the nozzle usage data will be disabled and the needle-free injection operation will be prohibited.

[0068] See also Figure 3 , Figure 3 is a schematic flow chart of a method for managing the use of an injection nozzle provided by an embodiment of the present invention, such as Figure 3 As shown, the method includes steps S1051 to S1054.

[0069] In some embodiments, the S105 includes: S1051 sets a first number threshold and a first duration threshold based on the preset nozzle usage restriction; S1052: when the current number of injections exceeds the first number threshold and / or the current injection duration exceeds the first duration threshold, generating a nozzle replacement reminder and writing the disabled tag into the nozzle usage data; After the nozzle replacement reminder is generated, the method further includes: S1053 sets a second number threshold and a second duration threshold based on the preset nozzle usage restriction; S1054: When the current number of injections exceeds the second number threshold and / or the current injection duration exceeds the second duration threshold, needle-free injection operation is prohibited.

[0070] The first number threshold is determined based on the optimal number of injections of the nozzle, and the first duration threshold is determined based on the optimal usage time of the nozzle. Within these two numerical ranges, the nozzle can maintain stable and good injection performance in needle-free injection.

[0071] Furthermore, the second number threshold is used to limit the absolute number of injections of the nozzle, and the second duration threshold is used to limit the absolute usage time of the nozzle. Within these two numerical ranges, although the nozzle can maintain good injection performance, there is a risk that the injection effect will gradually decline with the increase in duration or number of times. Beyond these two numerical ranges, the injection effect is difficult to guarantee.

[0072] Specifically, when the current number of injections exceeds the first number threshold and / or the current injection duration exceeds the first duration threshold, a nozzle replacement reminder is triggered, and a disabled tag is written into the usage information of the nozzle to prohibit the nozzle from being used again. Furthermore, a more stringent second number threshold and second duration threshold are set as supplementary measures. When the number of times or duration of use of the nozzle exceeds these more stringent limits, the needle-free injection operation will be directly prohibited to ensure the safety of the injection.

[0073] By setting two levels of thresholds and reminding users to replace the nozzle according to the preset nozzle usage restrictions, appropriate usage thresholds are reserved to provide preparation time for nozzle replacement while ensuring the injection effect. Operators can then flexibly control the timing of nozzle replacement based on actual scenarios such as the injection drug situation and user vital signs. This takes into account both the service life of the nozzle and the flexibility of actual operation, while also preventing potential risks caused by excessive use of the nozzle, thereby improving the user experience of medical institutions and their operators.

[0074] In some embodiments, the nozzle usage data also includes an injection drug label, and the method also includes: obtaining the injection drug label and the current usage data; based on a preset trauma recovery table, determining a minimum dosing interval according to the injection drug label and the current usage data, and determining the minimum dosing interval as a nozzle lock period; and writing a time limit disable tag corresponding to the nozzle lock period into the nozzle usage data.

[0075] The S103 also includes: if the detected disable tag is the time-limit disable tag, determining the validity of the time-limit disable tag based on the current time information and the nozzle lock period; if the current time information is in the nozzle lock period, confirming that the time-limit disable tag is valid; if the current time information is not in the nozzle lock period, confirming that the time-limit disable tag is invalid.

[0076] The injection drug label is generated based on the current injection drug information and is used to limit the use of the nozzle when injecting a specific drug. It should be noted that if the nozzle is used for the first time and there is no pre-set drug information, a drug label is generated according to the current injection drug information on the handpiece, and the drug label is written into the nozzle usage data as the injection drug label.

[0077] In some embodiments, the injection drug label is generated based on the injection drug information and random data. The random data can be a timestamp of the first injection time, a password entered by the user, etc., so that the injection drug label of each nozzle is unique.

[0078] Among them, the preset trauma recovery table is determined according to the physiological recovery of different doses of various drugs in actual needle-free injection after injection, and is not limited here.

[0079] Specifically, referring to the preset trauma recovery table, combined with the type of injected medicine, the number of injections corresponding to the current injection situation, the injection dose, etc., the minimum dosing interval is customized to ensure that the medicine is safely and effectively absorbed by the body, while avoiding tissue damage caused by frequent injections. During the minimum dosing interval, the nozzle is locked and the injection operation cannot be performed until the nozzle lock period ends. This time limit disabled label is recorded in the nozzle usage data for verification in subsequent use.

[0080] Correspondingly, in step S104, when a time-limit disabled tag is detected, the validity of the tag is determined based on the current time and the nozzle lock period. If the current time is still within the nozzle lock period, the time-limit disabled tag is confirmed to be valid and the injection operation is prohibited; if the current time has exceeded the nozzle lock period, the time-limit disabled tag is confirmed to be invalid and the injection operation is allowed to continue.

[0081] For example, in the medical beauty scenario, since the skin needs a certain amount of time to absorb and recover to ensure the maximum effect and reduce potential damage to the skin, the recommended interval after the water light needle injection is at least 30 days. Therefore, after user A completes the water light needle injection on January 1, 2024, the minimum dosing interval is 30 days, and the nozzle lock period is set from January 1, 2024 to February 1, 2024. The corresponding time limit disable tag is written into the nozzle usage data. When the time limit disable tag is detected, if the current time information is January 15, 2024, the current time information is in the nozzle lock period, and the time limit disable tag is confirmed to be valid; if the current time information is February 5, 2024, the current time information is not in the nozzle lock period, and the time limit disable tag is confirmed to be invalid.

[0082] This embodiment provides a dynamic nozzle locking mechanism based on drug information and usage data, which comprehensively considers the characteristics of different drugs, determines the minimum dosing interval according to the current user's injection trauma recovery, and then sets a lock period for the injection nozzle. During this period, the injection nozzle is locked and cannot be used, adaptively avoiding the user from illegally injecting excessive amounts without sufficient recovery during this period, reducing the risk of drug overdose or improper use. In addition, the setting of the nozzle lock period also avoids cross-infection caused by medical institutions mixing injection nozzles between different users, enhancing the safety of nozzle use.

[0083] In some embodiments, in order to avoid the medical institution replacing the nozzle midway and improve the effectiveness of the supervision of the injection nozzle, the nozzle chip is continuously detected in situ, and the method also includes: continuously verifying whether the valid code in the nozzle identity data has changed based on a preset interval; if the valid code has changed, it is determined that the nozzle has been replaced, the needle-free injection operation is prohibited, and S101 to S105 are re-executed.

[0084] The preset interval duration can be flexibly set according to actual needs and is not limited here. The specific contents of steps S101 to S105 can refer to the description in other embodiments of the present invention and will not be repeated here.

[0085] In some embodiments, the present invention also provides a method for managing the use of injection nozzles that covers the entire life cycle of the nozzle and flexibly takes into account both high utilization and high injection effect. It not only supervises the qualification and compliance of the nozzles during the injection process, but also takes into account the injection quality assessment of the nozzles during sustainable use. At the same time, it refines the resource management of the nozzles after they are discarded, providing a comprehensive regulatory framework for the sustainable use of needle-free syringe nozzles.

[0086] The nozzle data is traceable through the nozzle chip. By tracking the source and usage history of the nozzle, the product qualification, usage compliance and injection safety of the nozzle are ensured, and dynamic supervision is implemented to reasonably limit the overall usage threshold of the nozzle. In this process, the loss of the nozzle due to multiple uses is fully considered, and multi-level self-diagnosis of the injection nozzle performance is performed according to the usage of the nozzle. On the one hand, the nozzle performance is evaluated based on the residual drug dose after the injection. Furthermore, the nozzle suspected of being defective is evaluated again with a more precise single injection dose when the injection is repeated. While reusing the nozzle, more flexible and accurate nozzle quality monitoring is provided, which can timely detect nozzles with degraded performance and perform preventive maintenance to ensure injection safety and improve the reliability and stability of needle-free syringes.

[0087] Specifically, the nozzle chip detects and obtains nozzle traceability data including nozzle identity data and nozzle usage data, and performs product matching verification and usage compliance verification based on the nozzle traceability data. When the nozzle is qualified and there is no valid disable label, needle-free injection operation is allowed; the current usage data of the needle-free syringe is monitored, and the cumulative usage data in the nozzle usage data is updated according to the current usage data. At the same time, the drug consumption data of the needle-free syringe is monitored to evaluate the nozzle performance. When the cumulative usage data exceeds the preset nozzle usage limit or the current nozzle performance does not meet the standard performance threshold, the disable label is written into the nozzle usage data, and the needle-free injection operation is prohibited.

[0088] See also Figure 4 , Figure 4 is a schematic flow chart of a method for managing the use of an injection nozzle provided by another exemplary embodiment of the present invention, such as Figure 4 As shown, the method is applied to a needle-free injector, and includes steps S201 to S205.

[0089] S201 obtains nozzle traceability data of the nozzle based on nozzle chip detection, wherein the nozzle traceability data includes nozzle identity data and nozzle usage data, wherein the nozzle identity data includes a standard performance threshold, and the nozzle usage data includes cumulative usage data; S202: performing product matching verification based on the nozzle identity data, and if the nozzle identity data contains a valid code, determining that the nozzle is a qualified product; S203 detects whether there is a valid prohibition label in the nozzle usage data, and if there is no valid prohibition label, allows the needle-free injection operation by using compliance verification; S204 monitors the current usage data of the needle-free injector, updates the cumulative usage data according to the current usage data, and when the cumulative usage data exceeds the preset nozzle usage limit, writes the disable tag into the nozzle usage data and prohibits the needle-free injection operation; S205 monitors the drug consumption data of the needle-free syringe, evaluates the current nozzle performance according to the drug consumption data, and when the current nozzle performance exceeds the standard performance threshold, writes the disable tag into the nozzle usage data and prohibits the needle-free injection operation.

[0090] Among them, drug consumption data refers to parameters that reflect the drug consumption during the needle-free injection process, such as the single injection dose of the drug, the residual dose of the drug in the needle-free syringe after the needle-free injection is completed, the total injection dose, etc.

[0091] Among them, the current nozzle performance is manifested as a variety of actual parameter values ​​of the nozzle during the needle-free injection process, such as the single injection dose of the needle-free syringe, injection pressure, drug flow rate, injection uniformity, injection speed, injection depth and deviation, drug residue, dosage accuracy, etc.

[0092] Correspondingly, the standard performance threshold can be a standard parameter threshold of a series of nozzle performance that is flexibly set based on the safety and effectiveness of needle-free injection, or it can be the optimal performance parameter threshold corresponding to the nozzle model, for example, the standard single injection dose corresponding to the nozzle injection specification, the upper limit of drug residue, etc., which are not limited here.

[0093] Specifically, dynamic supervision is implemented to reasonably limit the overall usage threshold of the nozzles and standardize the reuse of nozzles. Furthermore, since the nozzles may be damaged during multiple uses, the changes in drug consumption data are monitored to evaluate the performance of the nozzles during needle-free injection. When the current evaluated nozzle performance exceeds the standard performance threshold, a disable tag is written to the nozzle usage data, and subsequent needle-free injection operations are immediately prohibited, so as to achieve timely identification and disabling of nozzles with degraded performance, implement strict control over the reuse of nozzles, improve the safety and effectiveness of needle-free injectors, and reduce medical risks.

[0094] It should be noted that step S204 and step S205 are performed simultaneously and in parallel, and there is no order of execution. The specific contents of steps S201 to S204 can refer to the description of steps S101 to S105 in other embodiments of the present invention, and will not be repeated here.

[0095] See also Figure 5 , Figure 5 It is a schematic flow chart of another method for use and management of an injection nozzle provided in an embodiment of the present invention.

[0096] like Figure 5As shown, in some embodiments, the drug consumption data includes the residual dosage of the drug in the needle-free syringe after the needle-free injection is completed, and the S205 includes: when the dosage of the drug in the needle-free syringe remains unchanged for a first preset time period, collecting the residual dosage of the drug; if the residual dosage of the drug is greater than the first preset value, the current nozzle performance does not meet the standard performance threshold, and the disabled tag is written into the nozzle usage data.

[0097] Among them, the first preset value is the upper limit of drug residue in the standard performance threshold. The specific first preset time duration and the first preset value are flexibly set based on actual conditions and are not limited here.

[0098] For example, taking the drug as a liquid, the first preset time is 20 minutes, the first preset value is 0.1 ml, and the drug dosage in the needle-free syringe remains unchanged within 20 minutes, that is, no further injection operation is performed, and no drug liquid is replenished. It can be determined that this injection operation has been completed. The current nozzle performance is evaluated based on the residual drug dosage after the injection. If the residual drug dosage is 0.02 ml at this time, the current nozzle performance meets the standard performance threshold; if the residual drug dosage is 0.15 ml at this time, the current nozzle performance does not meet the standard performance threshold, and the disabled tag is written into the nozzle usage data.

[0099] It should be understood that in the needle-free injection operation, in order to avoid over-injection or injection of air, the remaining part that cannot be completely injected by the nozzle will be omitted and not injected. For example, a nozzle with a single injection volume of 0.03 ml needs to inject a total of 3.02 ml of liquid medicine, and can only inject the corresponding integer part "3 ml". The remaining amount of "0.02 ml" will be omitted and not injected. Correspondingly, when the liquid medicine is introduced at the handpiece end, the liquid medicine is also introduced accurately according to 3 ml. If the performance of the needle-free syringe is good, the residual drug dose should be close to zero. Therefore, if the residual drug dose after the injection is completed is greater than the first preset value, it may be that the performance of the nozzle has declined, resulting in unstable amount of medicine ejected each time. Correspondingly, the same is true when the medicine is powder.

[0100] like Figure 5 As shown, correspondingly, if the drug residual dose is less than the first preset value, the drug residual dose is further compared with the second preset value. If the drug residual dose is less than the second preset value, the current nozzle performance meets the standard performance threshold, and needle-free injection is allowed to continue.

[0101] like Figure 5As shown, in some embodiments, the drug consumption data includes a single injection dose of a needle-free syringe, the nozzle identity data includes a nozzle injection specification, and the S205 also includes: if the residual drug dose is less than a first preset value and greater than a second preset value, writing a defect label into the nozzle usage data; when it is detected that the nozzle usage data includes the defect label, obtaining the nozzle injection specification, and continuously obtaining the single injection dose within a second preset time period; when the error between the single injection dose and the nozzle injection specification is greater than a preset error value, the current nozzle performance does not meet the standard performance threshold, and the disabled label is written into the nozzle usage data.

[0102] The nozzle injection specification refers to the standard single injection dose of the nozzle. The second preset duration, the second preset value, and the preset error value are flexibly set based on actual conditions and are not limited here.

[0103] Among them, the defect label is a label used to trigger real-time monitoring of nozzle performance. It is generated due to suspected failure of the nozzle, performance degradation, etc. The presence of a defect label in the nozzle usage data means that the nozzle may have injection safety risks and needs to be strictly monitored during continued use.

[0104] Exemplarily, the first preset value is 0.1 ml and the second preset value is 0.06 ml. If the residual drug dose is 0.05 ml at this time, although the current nozzle performance meets the standard performance threshold, the residual drug dose is still too large. When injected again, the defective label is detected, triggering real-time monitoring of the nozzle performance. The nozzle performance is monitored with a more precise single injection dose within the second preset time period. Once it is found that the error between the single injection dose and the nozzle injection specification is greater than the preset error value, the current nozzle performance does not meet the standard performance threshold, and the disabled label is written into the nozzle usage data.

[0105] In some embodiments, Figure 5 As shown, if the error between the single injection dose and the injection specification of the nozzle is less than the preset error value during the second preset time, the needle-free injection is allowed to continue and the defect label is deleted. The second preset time can be the entire needle-free injection process of the nozzle again or a longer time period to ensure stable nozzle performance.

[0106] By monitoring and analyzing drug consumption data, potential problems can be discovered and resolved in a timely manner, and the safety and effectiveness of needle-free syringes can be improved. On this basis, the embodiment of the present invention provides a multi-level self-diagnosis mechanism for injection nozzle performance based on the usage of the nozzle. On the one hand, the nozzle performance is evaluated based on the residual drug dosage after the injection, and the nozzle performance is only evaluated once after the nozzle completes the injection; further, for nozzles suspected of having defects, the nozzles suspected of being defective are evaluated again with a more precise single injection dosage when they are injected again, and the nozzle performance is monitored multiple times in real time within a certain period of time.

[0107] The multi-level self-diagnosis mechanism provides more flexible and accurate nozzle quality monitoring, provides reliability support for the reuse of nozzles, and can also optimize computing resource consumption to a certain extent, while improving the accuracy of self-diagnosis and avoiding misjudgment of nozzle damage due to handpiece defects.

[0108] In some embodiments, in order to improve transparency and security, an audit trail function can be added to the nozzle usage information to record each access and modification of the data, that is, the deletion of disabled labels and defective labels will also be recorded.

[0109] In some embodiments, the method further includes: based on a preset grading standard, evaluating the degree of usage loss and the degree of performance defects of the nozzle according to the accumulated usage data and the current nozzle performance; and generating a recycling grade label for the nozzle according to the degree of usage loss and the degree of performance defects.

[0110] Specifically, based on the preset grading standards, the usage status of the nozzle can be carefully evaluated. First, by collecting the cumulative usage data of the nozzle, including parameters such as the cumulative usage time and the cumulative number of uses, the degree of nozzle loss can be quantitatively analyzed. At the same time, the performance defect degree of the nozzle is evaluated by the residual drug dose, single injection dose, whether there is a defective label, whether the disabled label is written due to performance degradation, etc. These two evaluation results will serve as the basis for generating the nozzle recycling grade label.

[0111] In order to fully improve the utilization rate of injection nozzles, the nozzle loss and performance defects are carefully evaluated. The recycling grade label helps to guide the recycling and reuse process of the nozzles, and then quickly and accurately determine the recyclability of the injection nozzles and their recycling purposes. For example, for nozzles with low loss but high performance defects, they are set to D grade and can be recycled for product optimization research and development, nozzle manufacturer or batch supervision; for nozzles with low loss but low performance defects, they are set to A grade, and after recycling, they can be sold at a low price as environmentally friendly nozzles. In this way, the nozzles are properly handled after reaching the end of their service life, that is, the nozzle chip realizes all-round supervision of the entire life cycle of the nozzle, providing data support for future product development and market strategies, further refining the resource management after the nozzle is discarded, alleviating the problem of resource waste, and promoting the healthy development of needle-free injection technology.

[0112] In some embodiments, in order to avoid the medical institution replacing the nozzle midway and improve the effectiveness of the injection nozzle supervision, the nozzle chip is continuously detected in situ, and the method also includes: continuously verifying whether the valid code in the nozzle identity data has changed based on a preset interval; if the valid code has changed, it is determined that the nozzle has been replaced, the needle-free injection operation is prohibited, and S201 to S205 are re-executed.

[0113] The specific contents of steps S201 to S205 can be found in the description of other embodiments of the present invention, and will not be repeated here.

[0114] In some embodiments, the accumulated usage data includes the accumulated injection times and the accumulated injection duration, and the current usage data includes the current injection times and the current injection duration; S204 includes: adding the current injection times to the accumulated injection times to update the accumulated usage data; and / or adding the current injection duration to the accumulated injection duration to update the accumulated usage data. For details, please refer to the description in other embodiments of the present invention, which will not be repeated here.

[0115] In some examples, the needle-free injector includes a nozzle end and a hand tool end, and S201 includes: receiving electronic coded data in a readable and writable chip of the nozzle; decoding the electronic coded data based on a preset decoding algorithm by a decoder of the hand tool end to obtain the nozzle tracing data; or receiving the electronic coded data in the readable and writable chip of the nozzle; sending the electronic coded data of the hand tool end to the cloud, so that the cloud decodes the electronic coded data to obtain the nozzle tracing data, and receiving the nozzle tracing data sent by the cloud to the hand tool end. For details, please refer to the description in other embodiments of the present invention, which will not be repeated here.

[0116] In some embodiments, prohibiting the needle-free injection operation can be achieved by forcibly controlling the motor to stop running.
