Description

Technical Field

[0001] This application relates to the field of medical packaging performance testing, and in particular to a method, apparatus, equipment, and storage medium for testing the heat seal strength of medical packaging. Background Technology

[0002] The seal integrity of medical packaging products is one of the most important indicators in the performance evaluation of medical packaging products, and it has a crucial impact on medical safety. Heat sealing is currently one of the most commonly used sealing methods in medical packaging products, and it has a wide market application. To ensure the safety of medical products, it is necessary to test and verify the seal integrity or seal strength of medical packaging products, especially the heat seal strength.

[0003] Currently, the common method for testing and verifying the sealing strength, especially the heat-sealing strength, of medical packaging products is to calculate their Process Capability Index (CPK). Traditional CPK testing is a holistic verification method, requiring testing of all parts of the medical packaging product related to the tested performance. There is no cross-verification between these parts, resulting in an enormous workload. Taking the verification of the sealing strength of a flat bag as an example, N strips need to be continuously cut along the sealing area of ​​the flat bag at sampling points. At least three flat bag samples need to be collected at each sampling point, forming one group. The traditional CPK testing method requires at least 25 groups, therefore the minimum total number of test strips is N×3×25. Each strip needs to be tested separately, resulting in excessive time costs. When verifying the sealing strength of various types and large quantities of medical packaging products, this severely impacts the efficiency of the entire process. Therefore, designing a heat-sealing strength testing method for medical packaging products that improves the efficiency of sealing strength testing for heat-sealed medical packaging products remains a pressing technical problem that needs to be solved. Summary of the Invention

[0004] This application provides a method, apparatus, equipment, and storage medium for testing the heat seal strength of medical packaging, in order to solve the technical problem of low efficiency in existing methods for testing the heat seal strength of medical packaging.

[0005] According to a first aspect of the embodiments of this application, a method for testing the heat seal strength of medical packaging is provided, comprising: Based on the results of the internal pressure burst test of the product under test, several weak points of the product under test were identified.

[0006] Based on several weak points, multiple samples of the product to be tested are cut to obtain multiple test spline groups; the number of test splines in each test spline group is determined based on the number of weak points.

[0007] Heat seal strength tests were performed on each test strip group to obtain multiple sets of heat seal strength test data.

[0008] Based on the production specifications of the product under test and multiple sets of heat seal strength test data, the process capability index of the product under test is determined, and the heat seal strength of the product under test is determined based on the process capability index.

[0009] Compared to existing technologies that directly cut samples without identifying weak points, resulting in a large number of cut strips, this application determines several weak points of the product under test based on the results of the internal pressure burst test. Then, based on the number of weak points, it determines the number of test strips and cuts the sample. By determining the number of strips through identifying weak points and using the internal pressure burst test results as a theoretical basis for weak point identification, this approach reduces or avoids cutting and studying non-weak points. In other words, it eliminates unnecessary strip positions that do not affect the heat-sealing strength of the sample, reducing the number of strips without affecting the heat-sealing strength test results. The heat-sealing strength of the test strips obtained based on the weak point cutting is then tested to determine the process capability index and ultimately obtain the heat-sealing strength. By reducing the number of strips, the time required to test the heat-sealing strength of each strip is reduced, thereby improving the efficiency of the heat-sealing strength test of the product under test.

[0010] In some embodiments of this application, based on several weak points, multiple samples of the product to be tested are cut to obtain multiple test strip sets, specifically including: Based on several weak points, determine several spline cutting positions corresponding to the weak points of the product under test.

[0011] Based on the burst width of each weak point of the product under test, determine the number of spline cuts corresponding to each spline cutting position.

[0012] Based on several spline cutting positions and the corresponding number of spline cuts for the product under test, multiple samples of the product under test are cut to obtain multiple test spline sets.

[0013] This application first determines the cutting position of the sample strip corresponding to the product under test based on the weak points, which can avoid studying non-weak points, thereby reducing the number of samples and improving the efficiency of subsequent sample testing; then, it determines the number of sample strips to be cut based on the burst width of each weak point of the product under test, and then cuts multiple samples of the product under test, which conforms to the actual test and avoids subsequent test errors caused by positional and quantity errors, thus ensuring the accuracy of the test.

[0014] In some embodiments of this application, based on several weak points, several spline cutting positions corresponding to the weak points are determined for the product under test, specifically including: Based on the center of each weak point of the product under test, determine the center of the corresponding strip cutting position, and based on the burst width of each weak point of the product under test, determine the cutting width of the corresponding strip cutting position.

[0015] By combining the center position and cutting width of each strip cutting position, the cutting position of each strip of the product to be tested is determined.

[0016] This application determines the center of the corresponding strip cutting position by using the center of the position of each weak point of the product under test, and determines the cutting width of the corresponding strip cutting position by using the burst width of each weak point, thereby determining the strip cutting position. It can accurately locate the strip cutting position based on the center of the weak point and the burst width, avoiding errors in subsequent tests due to positional errors and ensuring the accuracy of the test.

[0017] In some embodiments of this application, the number of test splines in each test spline group is determined based on the number of weak points, specifically: ; in, This represents the total number of test splines in the current test spline set. This represents the total number of weak points in the product under test. For the first The number of spline cuts corresponding to each spline cut position. For the first The bulge width corresponding to the weak point at the spline cutting position.

[0018] According to a second aspect of the embodiments of this application, a medical packaging heat seal strength testing device is provided, including a weak point determination module, a strip cutting module, a sample testing module, and a strength determination module.

[0019] The weak point identification module is used to identify several weak points of the product under test based on the results of the internal pressure burst test.

[0020] The spline cutting module is used to cut multiple samples of the product under test based on several weak points to obtain multiple test spline groups; the number of test splines in each test spline group is determined based on the number of weak points.

[0021] The sample testing module is used to perform heat seal strength tests on each test strip group and obtain multiple sets of heat seal strength test data.

[0022] The strength determination module is used to determine the process capability index of the product under test based on the production specifications of the product under test and multiple sets of heat seal strength test data, and to determine the heat seal strength of the product under test based on the process capability index.

[0023] In some embodiments of this application, the spline cutting module includes a cutting position determination unit, a cutting number determination unit, and a test spline cutting unit.

[0024] The cutting position determination unit is used to determine the cutting positions of several spline strips corresponding to several weak points of the product under test, based on several weak points.

[0025] The cut count determination unit is used to determine the number of spline cuts corresponding to each spline cut position based on the burst width of each weak point of the product under test.

[0026] The test strip cutting unit is used to cut multiple samples of the product under test according to several strip cutting positions and the corresponding number of strip cuttings, so as to obtain multiple test strip sets.

[0027] In some embodiments of this application, the cutting position determination unit includes a position information determination subunit and a cutting position determination subunit.

[0028] The location information determination subunit is used to determine the location center of the corresponding strip cutting position based on the location center of each weak point of the product under test, and to determine the cutting width of the corresponding strip cutting position based on the burst width of each weak point of the product under test.

[0029] The cutting position determination subunit is used to determine the cutting position of each strip of the product under test by combining the position center and cutting width of each strip cutting position.

[0030] In some embodiments of this application, the number of test splines in each test spline group is determined based on the number of weak points, specifically: ; in, This represents the total number of test splines in the current test spline set. This represents the total number of weak points in the product under test. For the first The number of spline cuts corresponding to each spline cut position. For the first The bulge width corresponding to the weak point at the spline cutting position.

[0031] Compared to existing technologies that directly cut samples without identifying weak points, resulting in a large number of cut strips, this application determines several weak points of the product under test based on the results of the internal pressure burst test. Then, based on the number of weak points, it determines the number of test strips and cuts the sample. By determining the number of strips through identifying weak points and using the internal pressure burst test results as a theoretical basis for weak point identification, this approach reduces or avoids cutting and studying non-weak points. In other words, it eliminates unnecessary strip positions that do not affect the heat-sealing strength of the sample, reducing the number of strips without affecting the heat-sealing strength test results. The heat-sealing strength of the test strips obtained based on the weak point cutting is then tested to determine the process capability index and ultimately obtain the heat-sealing strength. By reducing the number of strips, the time required to test the heat-sealing strength of each strip is reduced, thereby improving the efficiency of the heat-sealing strength test of the product under test.

[0032] According to a third aspect of the embodiments of this application, a computer device is provided, comprising: a processor; a memory; and a computer program stored in the memory and configured to be executed by the processor; wherein the processor executes the computer program to implement a method for testing the heat seal strength of medical packaging as described in this application.

Attached Figure Description

[0034] Figure 1 This is a schematic flowchart illustrating a method for testing the heat seal strength of medical packaging according to certain embodiments of this application. Figure 2 This is a modular structure diagram of a medical packaging heat seal strength testing device shown in certain embodiments of this application. Detailed Implementation

[0035] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below in conjunction with the accompanying drawings are exemplary and are only used to explain some embodiments of this application, and should not be construed as limiting the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments shown in this application without inventive effort are within the protection scope of this application.

[0036] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, unless otherwise explicitly specified, "a plurality of" or "several" means two or more.

[0037] From a statistical perspective, the traditional method of verifying heat seal strength using CPK requires separate on-machine testing of all parts of the medical packaging product related to the performance being measured. A large sample size is used to ensure the reliability and stability of data analysis. However, during the verification process, many locations unrelated to heat seal strength are used as spline cutting locations, resulting in a large amount of information redundancy and a huge workload. This has a serious negative impact on the efficiency of verifying the heat seal strength of medical packaging products.

[0038] However, in reality, assuming uniform materials and stable equipment, the one or more sites in the sample with the highest correlation to heat-sealing strength are the weak points in the sample manufacturing process. These weak points are fixed and independent of the parameters used in the heat-sealing strength testing and verification process. The international standard ISO 16775 for packaging of sterile medical devices outlines worst-case scenarios for medical device packaging. Therefore, by using the worst-case scenario description of medical device packaging in ISO 16775 as a theoretical basis, and considering the actual situation of one or more weak points in current implementation, the cutting positions and number of spline cuts in the CPK method for verifying heat-sealing strength can be simplified. This avoids using locations unrelated to heat-sealing strength as spline cutting positions, reducing information redundancy. In other words, while ensuring the accuracy of heat-sealing strength testing and verification, reducing the number of spline cuts improves the efficiency of the CPK method for verifying heat-sealing strength.

[0039] Based on the above technical background and principles, please refer to Figure 1 This application provides a method for testing the heat seal strength of medical packaging, including steps S101 to S104, each step of which is as follows: Step S101: Based on the results of the internal pressure burst test of the product under test, identify several weak points of the product under test.

[0040] The reason for considering identifying weak points based on the internal pressure burst test results of the product under test is that, in the manufacturing process of medical device packaging, before the heat seal strength verification in performance qualification (PQ), operation qualification (OQ) is required to confirm that the functional parameters of the medical device packaging meet the specifications. The internal pressure burst test in the OQ qualification process evaluates the stability and integrity of the packaging under internal pressure. The burst point obtained in the internal pressure burst test can clearly represent the weak points in the current implementation and the worst-case scenario of medical device packaging as described in ISO 16775. Therefore, the weak points of the product under test can be identified based on the internal pressure burst test results, thereby determining the spline cutting location and the number of splines to be cut.

[0041] Step S102: Based on several weak points, cut multiple samples of the product to be tested to obtain multiple test strip groups; wherein, the number of test strips in each test strip group is determined based on the number of weak points.

[0042] In some embodiments of this application, based on several weak points, multiple samples of the product to be tested are cut to obtain multiple test strip sets, specifically including: Based on several weak points, determine several spline cutting positions corresponding to the weak points of the product under test.

[0043] Based on the burst width of each weak point of the product under test, determine the number of spline cuts corresponding to each spline cutting position.

[0044] Based on several spline cutting positions and the corresponding number of spline cuts for the product under test, multiple samples of the product under test are cut to obtain multiple test spline sets.

[0045] This application first determines the cutting position of the sample strip corresponding to the product under test based on the weak points, which can avoid studying non-weak points, thereby reducing the number of samples and improving the efficiency of subsequent sample testing; then, it determines the number of sample strips to be cut based on the burst width of each weak point of the product under test, and then cuts multiple samples of the product under test, which conforms to the actual test and avoids subsequent test errors caused by positional and quantity errors, thus ensuring the accuracy of the test.

[0046] In some embodiments of this application, based on several weak points, several spline cutting positions corresponding to the weak points are determined for the product under test, specifically including: Based on the center of each weak point of the product under test, determine the center of the corresponding strip cutting position, and based on the burst width of each weak point of the product under test, determine the cutting width of the corresponding strip cutting position.

[0047] By combining the center position and cutting width of each strip cutting position, the cutting position of each strip of the product to be tested is determined.

[0048] In some embodiments of this application, the position center of the strip cutting position corresponding to each weak point of the product under test can be set as the position center of each weak point, and the cutting width can be set as the bursting width of each weak point.

[0049] This application determines the center of the corresponding strip cutting position by using the center of the position of each weak point of the product under test, and determines the cutting width of the corresponding strip cutting position by using the burst width of each weak point, thereby determining the strip cutting position. It can accurately locate the strip cutting position based on the center of the weak point and the burst width, avoiding errors in subsequent tests due to positional errors and ensuring the accuracy of the test.

[0050] In some embodiments of this application, the number of test splines in each test spline group is determined based on the number of weak points, specifically: ; in, This represents the total number of test splines in the current test spline set. This represents the total number of weak points in the product under test. For the first The number of spline cuts corresponding to each spline cut position. For the first The bulge width corresponding to the weak point at the spline cutting position.

[0051] Specifically, in the formula for determining the total number of test strips in the current test strip group, the value "15" represents the test strip width in millimeters (mm). Generally, to maintain consistency with the testing and verification methods of other products or other tests, and to avoid data errors, the test strip width should be fixed at 15mm, but it can also be set to other values, such as 25.4mm.

[0052] Step S103: Perform heat seal strength tests on each test strip group to obtain multiple sets of heat seal strength test data.

[0053] In some embodiments of this application, the heat seal strength test method is based on pharmaceutical industry standards. Specifically, the heat seal strength test is performed based on the sealing strength of soft barrier materials in the sterile medical device packaging test method (YY / T 0681.2-2010).

[0054] Step S104: Based on the production specifications of the product under test and multiple sets of heat seal strength test data, determine the process capability index of the product under test, and determine the heat seal strength of the product under test based on the process capability index.

[0055] In some embodiments of this application, the process capability index of the product under test can be determined using data analysis tools. For example, the production specifications of the product under test and multiple sets of heat seal strength test data can be substituted into Minitab for analysis to obtain the CPK value (process capability index) of the product under test.

[0056] In some embodiments of this application, the process capability index of the product under test can be directly used as the heat seal strength of the product under test.

[0057] Compared to existing technologies that directly cut samples without identifying weak points, resulting in a large number of cut strips, this application determines several weak points of the product under test based on the results of the internal pressure burst test. Then, based on the number of weak points, it determines the number of test strips and cuts the sample. By determining the number of strips through identifying weak points and using the internal pressure burst test results as a theoretical basis for weak point identification, this approach reduces or avoids cutting and studying non-weak points. In other words, it eliminates unnecessary strip positions that do not affect the heat-sealing strength of the sample, reducing the number of strips without affecting the heat-sealing strength test results. The heat-sealing strength of the test strips obtained based on the weak point cutting is then tested to determine the process capability index and ultimately obtain the heat-sealing strength. By reducing the number of strips, the time required to test the heat-sealing strength of each strip is reduced, thereby improving the efficiency of the heat-sealing strength test of the product under test.
