Fluid products e.g. antibiotics, application device, has diaphragm arranged in fluid channel, spacing, fluid chamber and opening to measure flow rate through channel, spacing, chamber and opening which is flow throughable by hydraulic fluid

摘要

The device has a hydraulic reservoir (20) with hydraulic fluid. A mainspring (32) produces drive pressure on the hydraulic reservoir. A medicaments ampulla (60) with fluid products is designed in such a manner that the hydraulic fluid, which reaches an annular space, causes a discharge of the fluid products from the ampulla. A diaphragm (40) is arranged in a fluid channel, spacing, fluid chamber and opening for measuring the flow rate through the fluid channel, spacing, fluid chamber and opening, which is flow throughable by the hydraulic fluid.
