Hardware Interlocking for Drug Infusion Pumps & Ventilators

Bridging cybersecurity and patient physiological safety to prevent lethal drug overdoses caused by cyber compromise.

The Danger of Wireless Infusion Pump Exploits

Historical vulnerability research has shown that network-connected infusion pumps can be remotely hijacked to deliver lethal drug overdoses. MedicalHSM isolates the physical motor driver from the network processor, requiring an internal hardware coprocessor to cryptographically verify dosage commands against pre-programmed clinical safety ceilings.

Fail-Safe Motor Decoupling

If an invalid digital signature or altered dosage rate is detected, MedicalHSM physically opens the motor power circuit, forcing the pump into a safe gravity-stop state while triggering bedside acoustic alarms.

Hardware Dosage Bounds Checking: Silicon logic enforcing absolute maximum infusion rates (e.g. insulin, morphine).
Dual-Physician Digital Signatures: Requiring multi-signature cryptographic authorization for high-potency drugs.
Clinical Barcode Cross-Check: Verifying cryptographic match between patient wristband, drug vial, and pump order.
Anti-Brute Force Keypad Lockout: Hardware lockout timers preventing unauthorized bedside programming.
