Background and Identification
The Penlon A200SP is an Absorber/Ventilator interface to be used as part of a larger anesthesia system in adult, pediatric, and neonatal settings. Created by the British company Penlon, the A200SP Absorber is autoclavable and designed to be used as a part of a semi-closed breathing circuit for anesthesia.
The Penlon A200SP Absorber includes a “Pull-out and Raise” mechanism for easier mounting along with quick releases for the canister and breathing bag to facilitate cleaning and preparation for autoclaving without major disassembly.
The Penlon A200SP Absorber is made up of a bellows plate with a cylindrical ventilator bellows housing protruding from the top of the rectangular plate. Alongside the top of the baseplate, there are various switches for technicians to control the gas flow from the anesthesia system to the patient. Another canister is protruding below the plate, where the absorbent is housed for the inspiratory gas path. After passing through this absorbent the gas is passed to the patient through the inspiratory hose. The model number can be located on the reservoir bag side of the rectangular base plate, towards the expiratory hose connectors.
The Penlon A200SP Absorber was launched alongside the larger Prima SP anesthesia system in the early 2000s, with subsequent iterations of the system incorporating the technology until the SP 300 series introduced the A300SP Absorber.
The Penlon A200SP Absorber is compatible with Prima SP and SP2 anesthesia systems as well as the AV-S and AV800 Ventilator
