Irreversible Limiter for Medical Flow Regulator

The regulator is designed with a preliminary action principle where the flow rate is set by the operator before the patient uses the device. Once the desired flow rate is established, the regulator's design prevents any subsequent modification by the patient, ensuring the pre-set parameters are maintained throughout treatment.

The regulator acts as an intermediary mechanism between the operator's initial setting and the patient's usage. It translates the operator's flow rate selection into a controlled output that cannot be altered by the patient, serving as a protective barrier against unauthorized modification.

The regulator incorporates preliminary anti-action by designing the mechanism to prevent the harmful action of increasing flow rate to maximum. The physical design of the adjustment mechanism inherently blocks patient access to the maximum flow position, preemptively eliminating the safety risk before it can occur.

The design converts the potential harm of patient tampering into a beneficial safety feature. The very act of limiting adjustment capability, which might seem to reduce adaptability, actually creates a protective function that prevents dangerous flow rate changes while maintaining adequate adaptability for legitimate medical needs.
