The Trust where I work has just taken delivery of over 30 of the Asena PK devices, I believe, although we still have a number of Graseby 3500 TCI devices in circulation so I guess we still have a stock of 3500-dedicated prefilled syringes. We should have a considerable number in the workshop soon.
I have had my hands on the PK, CC, GH and GS recently, to do acceptance and pre-acceptance checks on evalution and some software upgrades and modifications in the past. They now use the standard Asena Mk3 hardware-platform I believe, so most parts are common to all devices in the range, except for labels and software, I suppose.
I reckon that Alaris will probably do a good job of updating and introducing more patient-models to the PK software as they are clinically validated and become available. Alaris products are quite easy to configure, calibrate and check but that's my personal opinion, of course.
Plus the technical and sales support given by Alaris is very good in comparison to some of the other suppliers and manufacturers. Our Anaesthetists had a couple of B.Braun systems on evaluation a while back, consisting of a CPU and networked syringe drivers, marketed by Datex-Ohmeda just before they were snapped-up by GE, I think.
