Description

Technical field:

[0001] The invention relates to an SPD surgical kit management system. Background technology:

[0002] The operating room is a place for patients to undergo surgery and rescue. It is an important technical department of the hospital. The operating room is connected to the surgical department and should be close to the blood bank, intensive care unit, anesthesia recovery room, etc. The operating room should be located in a quiet, clean location that is convenient for communication with related departments. Hospitals with low-rise buildings as the main body should choose to be located in the wing, while hospitals with high-rise buildings as the main body should choose the middle floor of the main building.

[0003] Due to the particularity of surgical departments, the billing operation of surgical consumables should be optimized as much as possible to reduce the time cost of the department and allow the medical staff of the department to have more time to serve patients. However, the existing surgical consumables management system is too single in function and lacks feedback detection links. It cannot break down and refine the use process of surgical consumables and manage and confirm them one by one, which leads to omissions in different links during the use of surgical consumables. At the same time, it cannot independently distinguish and manage surgical consumables according to their categories and values, and cannot quickly and accurately configure the required surgical kits from high-value or low-value consumables according to the type of surgery, thus failing to meet the needs of actual application scenarios. Summary of the invention:

[0004] The embodiment of the present invention provides an SPD surgical kit management system with a reasonable structural design. Based on the mutual cooperation of multiple functional modules, the various functions of the surgical kit management system are enriched, the corresponding process can be optimized as much as possible during billing operations, and a data feedback detection link can be set. The use process of the surgical kit can be decomposed and refined to manage and confirm it one by one, thereby reducing the time cost of the department so that the department staff can spend more time serving patients. In combination with the management requirements of the overall status of the hospital and the actual spatial layout of the department, a surgical kit management mode is customized and designed to avoid omissions of different categories of surgical kits during the aggregate use process, so that independent differentiation and management can be carried out according to the category and value of surgical consumables, and the required surgical kits can be quickly and accurately configured from high-value consumables or low-value consumables according to the type of surgery, meeting the actual application needs of modern operating rooms and solving the problems existing in the prior art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] An SPD surgical kit management system, the management system comprising:

[0007] A surgical kit data management module, which is used to analyze the number of surgeries, surgical classifications, and surgical consumables used in an operating room in a year, and to predict and select the quantity and specifications of surgical consumables in surgical kits in combination with an order quantity model;

[0008] A surgical kit packaging management module, which is used to pre-occupy inventory according to existing inventory information, introduce a hospital consumables inventory turnover rate calculation formula, perform inventory verification and pre-occupancy according to the principle of short-term expiration date priority and first-in-first-out, lock inventory information, and complete rapid and accurate packaging of surgical kits;

[0009] A surgical kit code scanning management module, which is used to use code scanning to send the packaged surgical kits out of the warehouse to the corresponding operating room;

[0010] A surgical kit return management module, which is used to perform a scan code return operation;

[0011] A surgical kit barcode query module is used to query the usage status and traceability information of each surgical kit within a period of time.

[0012] The management process of the management system includes the following steps:

[0013] S1, the surgical procedure is confirmed by medical staff;

[0014] S2, manage and count the consumables details of the surgical kit, analyze the specific quantity of each surgical consumable in the surgical kit and the number of surgical kits that need to be set based on the historical consumables consumption;

[0015] S3, configure information for the surgical kit and pack the surgical kit in the consumables warehouse;

[0016] S4, scan the box code of the surgical kit to carry out the system out of the warehouse, send the surgical kit to the operating room for acceptance, and the operating room operator selects the corresponding surgical kit according to the specific operation, scans the code in the system and arrives at the specific operating room to wait for billing;

[0017] S5: After the operation is completed, the medical staff counts the surgical consumables, fills in the surgical consumables usage statistics table, and performs surgical kit billing operations in the system;

[0018] S6, retrieve the unbilled surgical consumables, confirm the return according to the surgical kit outbound details, generate specific surgical consumables information and transmit it to the HIS system in real time through the interface for billing summary.

[0019] The order quantity model is:

[0020]

[0021] Where D is the demand, S is the cost of each order, and H is the unit holding cost;

[0022] The order quantity model can accurately predict the quantity and frequency of items required for surgery, which can be estimated through historical data, seasonal changes, and future surgery plans.

[0023] The operation steps of the surgical kit data management module are:

[0024] Collect hospital surgical kit data templates, including: kit type, number of kits, type of consumables in the kit and quantity of consumables in the kit; add new types of surgical kits for maintenance, add types and quantities of surgical consumables, and compose and activate surgical kits.

[0025] The hospital consumables inventory turnover rate calculation formula is:

[0026]

[0027] The evaluation inventory value is:

[0028]

[0029] The operating steps of the surgical kit packaging management module are as follows: select the surgical consumables that need to be packaged for one-click centralized packaging; after packaging is completed, the system will generate a one-dimensional code with the "kit code number" and print the box code and paste it on the box, and print out the picking list related to the surgical kit consumables; if the packaged surgical kit is no longer used, it will be actively unpacked to release the reserved inventory.

[0030] The operation steps of the surgical kit code scanning management module are: collect surgical kits from the operating room warehouse, and send the packaged surgical kits out to the corresponding operating room; scan the box code to add surgical kit information, and review and save the surgical kit information.

[0031] The operation steps of the surgical kit return management module are: checking whether the physical objects returned from the operating room are consistent with the usage information recorded in the system, confirming the specific return quantity of surgical consumables, generating specific billing information, and automatically unlocking the remaining unbilled quantity, releasing the department inventory, and waiting for the next packaging;

[0032] During the operation, consumables used during the operation may not be in the package, or the consumables in the package may exceed the set quantity. The excess needs to be recorded. Enter the hospitalization number to bring up the patient information, add the consumable information, fill in the quantity used, save and review, and generate a usage order.

[0033] In the surgical kit barcode query module, the operating room inventory can be modeled and monitored. To prevent abnormal inventory shortages, a safety stock model can be used for analysis. The safety stock is an additional stock set up to cope with the uncertainty of demand. The safety stock model is:

[0034]

[0035] Where Z is the quantile of the standard normal distribution corresponding to the service level, σ d is the standard deviation of daily demand, LT is the lead time;

[0036] The quantiles of the standard normal distribution are the values ​​corresponding to specific probability points of the cumulative distribution function of the standard normal distribution. These quantiles are used to determine the number of standard deviations from the mean that a random variable will fall under a given probability, and can estimate the percentage of data below a certain value in the population; in hypothesis testing, these quantiles can also be used to determine the critical value of the rejection domain; specifically, in the safety stock model, based on the hospital's sophisticated management of operating rooms and the management requirements of operating room managers, Z = 2.58 is used; it corresponds to a probability point of approximately 99%, which means that the accuracy of consumables is guaranteed to be 99%.

[0037] The standard deviation of daily demand is a statistical indicator to measure the degree of change in daily demand, and is used to indicate the degree of deviation between the daily demand data point and its average value; the larger the standard deviation, the higher the volatility of daily demand; the smaller the standard deviation, the relatively stable daily demand;

[0038] The standard deviation of daily demand can also be used to calculate safety stock to cope with demand uncertainty. When calculating safety stock, the standard deviation of daily demand is used to estimate the range of demand changes during the lead time. The standard deviation of a single commodity is calculated as above.

[0039] The present invention adopts the above structure, and analyzes the annual surgical volume, surgical classification and surgical consumables usage of the operating room through the surgical kit data management module, and predicts and selects the quantity and specifications of surgical consumables in the surgical kit in combination with the order quantity model; the surgical kit packaging management module performs advance inventory pre-occupancy according to the existing inventory information, introduces the hospital consumables inventory turnover rate calculation formula, and performs inventory verification and inventory pre-occupancy according to the principle of short-term expiration priority and first-in-first-out, locks the inventory information, and completes the rapid and accurate packaging of the surgical kit; the surgical kit scanning management module uses the scanning form to send the packaged surgical kit out of the warehouse to the corresponding operating room; the surgical kit return management module performs the scanning return operation; the surgical kit barcode query module queries the usage status and traceability information of each surgical kit within a period of time, which has the advantages of accuracy, efficiency, safety and reliability.

[0063]

[0064] The evaluation inventory value is:

[0065]

[0066] The operating steps of the surgical kit packaging management module are as follows: select the surgical consumables that need to be packaged for one-click centralized packaging; after packaging is completed, the system will generate a one-dimensional code with the "kit code number" and print the box code and paste it on the box, and print out the picking list related to the surgical kit consumables; if the packaged surgical kit is no longer used, it will be actively unpacked to release the reserved inventory.

Enter the hospitalization number to bring up the patient information, add the consumable information, fill in the quantity used, save and review, and generate a usage order.

[0070] In the surgical kit barcode query module, the operating room inventory can be modeled and monitored. To prevent abnormal inventory shortages, a safety stock model can be used for analysis. The safety stock is an additional stock set up to cope with the uncertainty of demand. The safety stock model is:

[0071]

[0072] Where Z is the quantile of the standard normal distribution corresponding to the service level, σ d is the standard deviation of daily demand, LT is the lead time;

[0073] The quantiles of the standard normal distribution are the values ​​corresponding to specific probability points of the cumulative distribution function of the standard normal distribution. These quantiles are used to determine the number of standard deviations from the mean that a random variable will fall under a given probability, and can estimate the percentage of data below a certain value in the population; in hypothesis testing, these quantiles can also be used to determine the critical value of the rejection domain; specifically, in the safety stock model, based on the hospital's sophisticated management of operating rooms and the management requirements of operating room managers, Z = 2.58 is used; it corresponds to a probability point of approximately 99%, which means that the accuracy of consumables is guaranteed to be 99%.

[0074] The standard deviation of daily demand is a statistical indicator to measure the degree of change in daily demand, and is used to indicate the degree of deviation between the daily demand data point and its average value; the larger the standard deviation, the higher the volatility of daily demand; the smaller the standard deviation, the relatively stable daily demand;

[0075] The standard deviation of daily demand can also be used to calculate safety stock to cope with demand uncertainty. When calculating safety stock, the standard deviation of daily demand is used to estimate the range of demand changes during the lead time. The standard deviation of a single commodity is calculated as above.

[0076] The working principle of an SPD surgical kit management system in an embodiment of the present invention is as follows: based on the mutual cooperation of multiple functional modules, the various functions of the surgical kit management system are enriched, the corresponding process can be optimized as much as possible during billing operations, and a data feedback detection link can be set up. The use process of the surgical kit can be decomposed and refined and managed and confirmed one by one, reducing the time cost of the department so that department staff can spend more time serving patients; combined with the management requirements of the overall status of the hospital and the actual spatial layout of the department, a customized design and development of the surgical kit management mode is carried out to avoid omissions of different categories of surgical kits during the aggregate use process, and then independent differentiation and management can be carried out according to the category and value of surgical consumables, and the required surgical kits can be quickly and accurately configured from high-value consumables or low-value consumables according to the type of surgery to meet the actual application needs of modern operating rooms.

[0077] In the overall solution, the management system mainly includes: a surgical kit data management module, which is used to analyze the number of surgeries, surgical classifications and surgical consumables used in the operating room in a year, and predict and screen the quantity and specifications of surgical consumables in the surgical kit in combination with the order quantity model; a surgical kit packaging management module, which is used to pre-occupy inventory according to existing inventory information, introduce the hospital consumables inventory turnover rate calculation formula, and perform inventory verification and inventory pre-occupancy according to the principle of short-term priority and first-in-first-out, lock inventory information, and complete rapid and accurate packaging of surgical kits; a surgical kit scanning management module, which is used to use scanning to send the packaged surgical kits out of the warehouse to the corresponding operating room; a surgical kit return management module, which is used to perform scanning return operations; a surgical kit barcode query module, which is used to query the usage status and traceability information of each surgical kit within a period of time.

[0078] Corresponding to the system, the management process includes the following steps: confirming the surgical process through medical staff; managing and counting the consumables details of the surgical kit, analyzing the specific quantity of each surgical consumable in the surgical kit and the number of surgical kits that need to be set based on the historical consumables consumption; configuring the information of the surgical kit, and packing the surgical kit in the consumables warehouse; scanning the box code of the surgical kit for system outbound delivery, and sending the surgical kit to the operating room for acceptance. The operating room operator selects the corresponding surgical kit according to the specific operation, scans the code in the system, arrives at the specific operating room and waits for billing; after the operation is completed, the medical staff counts the surgical consumables, fills in the surgical consumables usage statistics table, and performs surgical kit billing in the system; retrieves the unbilled surgical consumables, confirms the return according to the outbound delivery details of the surgical kit, generates specific surgical consumables information, and transmits it to the HIS system in real time through the interface for billing summary.

[0079] In the surgical kit data management module, the types and quantities of kits are set by analyzing the annual surgical volume and surgical classification of the operating room, combined with the number of specific kit packing boxes; the surgical consumables details in the surgical kit are set by analyzing the annual consumables usage in the operating room, filtering out specific consumable names, consumable specifications and other information, while taking into account various factors such as replacement of new consumables.

[0080] Furthermore, the order quantity model is:

[0081]

[0082] Where D is the demand, S is the cost of each order, and H is the unit holding cost;

[0083] The order quantity model can accurately predict the quantity and frequency of items required for surgery, which can be estimated through historical data, seasonal changes, and future surgery plans.

[0084] Correspondingly, the operating steps of the surgical kit data management module are: collect hospital surgical kit data templates, including: kit type, number of kits, type of consumables in the kit and quantity of consumables in the kit; add and maintain new types of surgical kits, append types and quantities of surgical consumables, and compose and activate surgical kits.

[0085] When packing surgical kits, inventory will be pre-occupied according to the existing inventory information, and inventory verification and inventory pre-occupation will be carried out according to the principle of shortest expiration date first and first in first out, and the inventory information will be locked; the operating steps of the surgical kit packaging management module are: select the surgical consumables to be packaged for one-click centralized packaging; after packaging is completed, the system will generate a one-dimensional code with the "kit code number" and print the box code and paste it on the box, and print out the picking list related to the surgical kit consumables; if the packaged surgical kit is no longer in use, it can be actively unpacked to release the pre-occupied inventory.

[0086] If multiple prices appear for multiple batches of a single consumable, a multi-price calculation formula needs to be introduced. Specifically, the hospital consumable inventory turnover rate calculation formula is:

[0087]

[0088] The evaluation inventory value is:

[0089]

[0090] After the surgical kit is packed, it needs to be scanned and shipped out. Correspondingly, the operating steps of the surgical kit scanning management module are: collect the surgical kit from the operating room warehouse, and ship the packaged surgical kit out to the corresponding operating room; scan the box code to add the surgical kit information, and review and save the surgical kit information.

[0091] If the surgical kit is shipped from the warehouse to the operating room and is not used, you can scan the QR code to return the kit. The operation is the same as the shipping process.

[0092] The return of surgical kits requires multiple operations in the operating room, warehouse, system, etc. Check and confirm in the corresponding interface of the system, enter the patient's hospitalization number, the system will capture the patient information in the HIS patient view, and scan the surgical kit code for return review; after the use in the operating room is completed, the resident office staff must conduct a one-step recovery confirmation to check whether the physical objects returned from the operating room are consistent with the usage information recorded in the system. If they are inconsistent, the resident office staff can modify the return number in the corresponding interface after confirmation with the circulating nurse in the operating room, and finally generate a usage order based on the number of recovery confirmations.

[0093] During the operation, consumables used during the operation may not be in the package, or the consumables in the surgical package may exceed the set quantity. The excess part needs to be entered in the corresponding interface. Enter the hospitalization number to bring up the patient information, add the consumable information, fill in the usage quantity, save and review, and then generate a usage order.

[0094] After the consumables in the package are charged, if you want to make a refund, you need to operate on the corresponding page, enter the hospitalization number, and the patient's package usage data will be brought out. Enter the return quantity, save and review, and the corresponding sales return document can be generated; after the non-package consumables are charged, if you want to make a refund, you need to operate on the corresponding page, enter the billing usage order number, and the usage data will be brought out. Enter the return quantity, save and review, and the corresponding sales return document can be generated.

[0095] Furthermore, in the surgical kit barcode query module, the operating room inventory can be modeled and monitored. To prevent abnormal inventory shortage, a safety stock model can be used for analysis. The safety stock is an additional stock set up to cope with the uncertainty of demand. The safety stock model is:

[0096]

[0097] Where Z is the quantile of the standard normal distribution corresponding to the service level, σ d is the standard deviation of daily demand, LT is the lead time; the quantiles of the standard normal distribution are the values ​​corresponding to specific probability points of the cumulative distribution function of the standard normal distribution. These quantiles are used to determine the number of standard deviations from the mean that a random variable will fall under a given probability, and can estimate the percentage of data below a certain value in the population; in hypothesis testing, these quantiles can also be used to determine the critical value of the rejection domain; specifically, in the safety stock model, according to the hospital's sophisticated management of operating rooms and the management requirements of operating room managers, Z = 2.58 is used; it corresponds to a probability point of approximately 99%, that is, ensuring 99% accuracy of consumables is a prerequisite.

[0098] The standard deviation of daily demand is a statistical indicator to measure the degree of change in daily demand, and is used to indicate the degree of deviation between the daily demand data point and its average value; the larger the standard deviation, the higher the volatility of daily demand; the smaller the standard deviation, the relatively stable daily demand;

[0099] The standard deviation of daily demand can also be used to calculate safety stock to cope with demand uncertainty. When calculating safety stock, the standard deviation of daily demand is used to estimate the range of demand changes during the lead time. The standard deviation of a single commodity is calculated as above.

[0100] It is particularly noted that, in actual operation, binary variables can be introduced to convert surgical package management factors into a combination of threshold conditions and logical conditions, and the combination of threshold conditions and logical conditions can be converted into linear constraints involving logical variables.

[0101] Specifically, the combination of the threshold condition and the logic condition is:

[0102]

[0103] Among them, the conjunction It means "if and only if";

[0104] The logical variable δ v The linear constraints are:

[0105]

[0106] Among them, v l and v u are the lower and upper limits of the relative quantity deviation v of surgical kits and surgical consumables; ε>0 is the tolerance, which is usually computer precision; through linear constraints and binary variables, surgical kits are judged and managed more carefully, thereby further improving the management accuracy and practicality of the system.

[0107] To sum up, an SPD surgical kit management system in an embodiment of the present invention is based on the mutual cooperation of multiple functional modules, enriches the various functions of the surgical kit management system, can optimize the corresponding process as much as possible during billing operations, sets up data feedback detection links, and can decompose and refine the use process of surgical kits and manage and confirm them one by one, thereby reducing the time cost of the department and allowing department staff to spend more time serving patients; combined with the management requirements of the overall status of the hospital and the actual spatial layout of the department, a customized design and development of a surgical kit management mode is carried out to avoid omissions of different categories of surgical kits during the aggregate use process, and then independently distinguish and manage according to the category and value of surgical consumables, and quickly and accurately configure the required surgical kits from high-value consumables or low-value consumables according to the type of surgery to meet the actual application needs of modern operating rooms.

[0108] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.

[0109] The matters not described in detail in the present invention are all known technologies to those skilled in the art.

The SPD surgical kit management system according to claim 8, characterized in that: The standard deviation of daily demand is a statistical indicator to measure the degree of change in daily demand, and is used to indicate the degree of deviation between the daily demand data point and its average value; the larger the standard deviation, the higher the volatility of daily demand; the smaller the standard deviation, the relatively stable daily demand; The standard deviation of daily demand can also be used to calculate safety stock to cope with demand uncertainty. When calculating safety stock, the standard deviation of daily demand is used to estimate the range of demand changes during the lead time. The standard deviation of a single commodity is calculated as above.
