Fig. 9.1 Schematic of surgeons and nurses performing a surgical procedure with SurgiBox
personal protective equipment or further draping the patient but reduces the burden
of both (Fig. 9.1).
A rechargeable battery powers a microcontroller and fan so the system can be used
off-grid. The airflow is high initially for rapid system inflation but is subsequently
turned down to a maintenance flow to maintain the pressure inside the enclosure
(Fig. 9.2).
9.3.2 Particle Testing
The rigid frame system consistently achieved 0 particle count at all test sites within
90 s, or after 2.75 air changes. The minimal frame system consistently achieved
target thresholds even before completion of insufflation. Importantly, both systems
maintained acceptable thresholds with open ports.
