The peritoneal dialysis tubing ring bonding firmness tester is designed and manufactured according to the pharmaceutical industry standards of the People's Republic of China, and the instrument conforms to the "YY0030-2004 peritoneal dialysis tubing" and "GB T15812".1-2005 Non-endovascular Catheters Part 1: General Performance Test Methods" and other test standards.
Introduction to the test method for the adhesion firmness of the collar:
1. The peritoneal dialysis tubing that fixes the sleeve before temporary use shall be fixed according to the method provided by the manufacturer.
2 Immerse the peritoneal dialysis tubing in sodium chloride solution at a temperature of (3712) and a mass concentration of 9g l for 24 h and 1h, remove it and dry the surface, and then perform the following tests.
3 Hold both ends of the peritoneal dialysis tubing, stretch it to 150% of the full length, and hold it for 15 seconds before recovery. Press Figure AAs shown in 1, put the weight of 10N on the silicone rubber tube, (if necessary, put a suitable gasket between the weight and the collar), slowly lift the silicone rubber tube for 15s, and check whether there is any loosening between the collar and the silicone rubber tube.
The peritoneal dialysis tubing ring bond firmness test is an important test to evaluate the strength of the connection between the peritoneal dialysis tubing ring and the tubing. Here are some key takeaways from the test:
1. Prepare test equipment: including pressure testing machines, sensors, brackets and fixtures, etc. Ensure that the test equipment is accurate and reliable, and can simulate the pressure conditions in real use.
2. Install the test sample: connect the peritoneal dialysis tube ring with the tubing to ensure that the connection is firm. The attached sample is then mounted on the test holder to ensure that the sample is stable.
3. Perform a pressure test: During the test, gradually apply pressure to the junction between the peritoneal dialysis tube ring and the tubing. Observe the connection for looseness, leakage, or other damage.
4. Data Logging: Record the pressure value applied, the reaction at the connection, and any observed damage. This data will be used to evaluate the bonding strength of the collar.
5. Result analysis: According to the test data, analyze the performance of the collar under different pressures. Determine the maximum pressure it can withstand, and whether there is any damage at that pressure. This will help to evaluate the bonding strength and quality of the collar.
6. Judging criteria: Generally, if the collar does not appear loose, leakage or other damage under the specified maximum pressure, it can be considered that it has passed the adhesive firmness test. However, the specific criteria may vary depending on the product type and criteria.
7. Follow-up measures: If the test results are not satisfactory, the bonding process of the collar needs to be improved or redesigned. This may include efforts to improve the selection of adhesives, optimize the bonding process, or enhance quality control.
