L' Alcor's Advanced Cryoprotective Perfusion System (ACPS) è stato ultimato
(migliorato): al di là delle varie modifiche tecniche (che sono ben descritte
nell'articolo), questo miglioramento porterà ad una riduzione sostanziale
dell'apparecchio (rispetto ai modelli precedenti) e e dei vari componenti atti
alla perfusione (Introduzione artificiale di liquido attraverso i vasi
sanguigni) che saranno meglio adattati alla base del sistema di pompaggio
dell'azoto.

In the last update we reported that Alcor's Advanced Cryoprotective Perfusion
System (ACPS) was awaiting final wiring of the system. The panel containing the
refractometers and temperature monitoring systems, as well as other assorted
electronics, has now been wired for use. The programmer is currently assembling
all of the discrete components of the system into a single batch process for
operation.

The patient enclosure, which will be used in conjunction with the ACPS during
the cryopreservation process, has also seen modification. One change was to
increase the size of the heat exchange area of the OR table where nitrogen will
circulate for cooling. This made the enclosure taller, so we are reconsidering
the use of a standard-height operating table. Another change was to miniaturize
the chiller, which uses liquid nitrogen to cool and precisely control the
temperature of the cryoprotectant as it enters the patient. These changes will
enable a significant amount of floor space to be recovered (compared to the
previous design) and all perfusion components (except the perfusate itself) to
fit on the pump base.
