Injection process, especially for injecting patients with insulin, involves using a needleless pressure jet, where the pressure and injection signal are controlled based on skin electrical resistance.

摘要

A process for the painless injection of medicines in liquid form, especially insulin, involves using a needleless pressure jet. The injection pressure and the injection signal shape are controlled based on the measured electrical resistance of the skin, so the liquid can be injected into specific skin layers (9). The amount of medicine required is calculated based on patient data.
