Linear solenoid for controlling medication mixtures

The task

To develop a technique for injecting a medication in the correctly mixed quantity during combination chemotherapy.

Our solution

Combination chemotherapy involves injecting different cytostatic drugs into the patient's body. It is extremely important that the exact amount is delivered at exactly the right time.

The lines that control the mixing ratio of different cytostatic drugs must be able to be reliably opened and closed for this purpose. To ensure that they could be, we used a monostable linear solenoid that was precisely matched to the shore strength of the line.

The biggest challenge lay in aligning the interplay between lifting, holding and spring forces: we started by calculating the lifting force to close the line, then checked the holding force of the magnet to ensure that it would remain closed. In the third step, we made sure that the spring built into the magnet was strong enough to release the line.
