LG15811-T Needle Firmness Tester is used to test the breaking force of the tube, the connection strength of the catheter and the catheter joint, the connection between the needle holder and the needle tube, the connection between the liner and the liner and so on. Pull-off tests and tests with holding force and set time can be selected.
LG15811-T firmness tester is mainly used to determine the physical properties of link firmness and breaking force at the link of medical consumables, and is one of the important means to identify the firm performance of various links.
The following is the usual test method of the injection needle firmness tester:
1.Preparation:
Make sure the test instrument is set up and calibrated correctly.
Prepare the syringe and needle to be tested.
According to the test requirements, select the appropriate test parameters and methods.
2.Installation test sample:
Assemble the syringe and needle to be tested into the test fixture, ensuring that its connecting part is fully clamped and in a stable state.
3.Apply force:
A test instrument is used to apply a certain pulling or twisting force to the connecting part of the syringe and the injection needle.
The applied force should comply with the relevant standard or specification requirements and be gradually increased as needed until a pre-set test endpoint is reached or loosening or damage is observed.
4.Recording test data:
During the application of force, the pull-out or torsional force data displayed by the test instrument is recorded in real time.
The maximum pull-out or torsional force value at the end of the test is recorded, and the state of the connected parts is recorded, including whether loosening, damage, or deformation have occurred.
5.Analysis of results:
Based on the test data and observations, the firmness and stability of the connection between the injection needle and the syringe were evaluated.
Compare the test results with the standard requirements or product specifications to determine whether the test samples meet the quality control requirements or product design standards.
6.Reporting & Logging:
Write a test report, including test sample information, test methods, test results and analysis conclusions.
Document any anomalies during the test, observed phenomena, and actions taken.
7.Conclusions and Recommendations:
Based on the test results, conclusions are drawn and recommendations are made, including the possibility of product improvement, recommendations on quality control, etc.
If necessary, further improvements can be made in product design, manufacturing processes or material selection.
