Automated Testing of Medical Applications

Depending on the requirements, ZwickRoell testing systems for medical applications can be equipped with manual, semi-automatic or fully automatic specimen feeding, or enable serial or parallel tests.

AUTOINJECTORS LUER LOCK CONNECTIONS PEN INJECTOR / INSULIN PEN Residual Seal Force (RSF) Glide force test on multiple syringe systems Serial testing of syringes Automated testing of syringes

Automated testing of autoinjectors to ISO 11608-5

When dealing with large production batches, a testing process that saves time and resources is often important. ZwickRoell offers scalable automation solutions for a wide range of requirements.

The testing assistant roboTest N supports the user with simple applications. Typically, the testing of 30 autoinjectors can be automated with one magazine filling.

The system can be easily and flexibly adapted to changing test requirements without requiring any special programming knowledge.

The fully automated robotic testing system roboTest R performs the complete test sequence from removal of the cap, through testing of the autoinjectors, to disposal of the tested specimens and good/bad sorting. To ensure reliable and comparable test results, the measuring equipment is automatically verified on a daily basis (Daily Check). Due to using several autoinjector testing systems, even a large volume of specimens is processed quickly and reliably by roboTest R.

ISO 80369 – Automated testing of Luer lock connectors

When dealing with large production batches, a testing process that saves time and resources is often important. ZwickRoell provides a simple solution for automated testing of Luer lock connectors.

The testing assistant roboTest N supports the user in performing the test to ISO 80369.Typically, 30 Luer Lock connectors can be tested automatically with one magazine filling. The testing assistant transports the specimen from the magazine to the Luer Lock testing system and positions it in the specimen grips. Here, the thread as well as the seal tightness of the Luer Lock connector are tested. The testing assistant roboTest N then removes the specimen from the machine and returns it to the magazine.

The system can be easily and flexibly adapted to changing test requirements without requiring any special programming knowledge. For all robotic testing systems, the autoEdition3 automation software is used for information input and control.

Automated testing of insulin pens and pen injectors to ISO 11608

Performing a test on insulin pens using an automated testing system together with the zwickiLine materials testing machine with integrated torsion drive ensures reliable and cost-effective test results . Only one test fixture is needed to check a variety of insulin pen functions. This system allows you to measure the dosage setting, actuation force, glide force, and specified dosage in one continuous process. You can modify and combine the test methods of both test axes to suit your testing needs. The robotic testing system roboTest R is responsible for automated specimen feeding.

It uses the automation software autoEdition3 to remove insulin pens from the magazine, feed them into the testing machine, and start the test. This minimizes the possibility of inaccurate test results due to operator influence. Our solution makes the test process significantly more efficient thanks to increased specimen throughput. It is also possible to manually test specimens at any time.

testXpert III together with the Expanded Traceability option to FDA 21 CFR Part 11 make it possible to create documentation for the testing process that is complete and tamper proof.

Parallel glide force tests on multiple syringe systems

One application is for example, syringes used in syringe drivers. In this case the syringe plungers are depressed over a lengthy period. To reduce the test time the testing machine can be upgraded to 6-8 test axes with the corresponding number of load cells. This enables individual force recording for each syringe.

This fixture comprises an AllroundLine table top testing machine expanded to 6–8 test axes to hold the corresponding number of load cells. The syringe holding fixture can accommodate syringes of various sizes, as well as two medium containers for catching the expelled liquid. This fixture can be used to test frictional forces on cartridges. The force sequences can be synchronized thanks to the individual height adjustment feature.

Materials testing machine with rotating magazine for syringe testing

Automated testing of syringes

The production in large batches often requires a time- and resource-saving test process. With the testing assistant roboTest N, ZwickRoell offers an easy solution for automated testing of syringes.

The testing assistant roboTest N supports the user in performing tests to ISO 11040, for example. The system can be used to automatically test a smaller batch of syringes.

Various test methods, including testing of the plunger glide force and testing of the cap-removal force can be performed with the same machine. To identify the test method currently in use, the testing assistant roboTest N uses a scanner to verify the installed equipment and the specimens in the magazine for consistency before testing the first specimen.

The testing assistant then transports a specimen from the magazine to the testing machine and positions it in the corresponding specimen grips. To test the plunger glide force, the syringe plunger is pressed in via a compression test. To determine the syringe cap-removal force, the cap is removed via a tensile test. The testing assistant roboTest N then removes the specimen from the machine and returns it to the magazine.

With the appropriate test arrangement, it is also possible to carry out additional tests described in the ISO 11040 standard.

The system can be easily and flexibly adapted to changing test requirements without requiring any special programming knowledge. Input and control is realized through the autoEdition3 automation software that is implemented in all automated testing systems.
