X-Message-Number: 17359 Subject: Intoducing the VPS pt1 From: "Lionel Vogt" <> Date: Thu, 23 Aug 2001 10:56:51 -0400 I was asked to repost this here concerning my construction of the prototype this is my last post for abit as I need to spend as much time as I can on getting this built I have to post this in three parts because of its size. I do need any doctors out there who have experiance in cryonics to please contact me. I want to make this system as effective as possible. Lionel Vogt VPS Vogt Presuspension System What is the VPS ? The Vogt Presuspension System is a cooling device designed to start the immediate cooling of the brain at the moment of death -- or as near to that moment as it can be implemented to help prevent deterioration to the brain after death has occurred Why is this unit needed? The VPS is a system designed to help solve one of the issues that had been a serious concern: A lack of an advanced and compact refrigeration method. Current methods require a team, with the co-operation of a hospital, to transport or scavenge ice to cool a patient before freezing. A theoretic example: If a patient were to die suddenly outside the care of ALCOR, they would be required to fly, either with all the ice and cooling materials needed to minimize the damage being done to brain by waiting to be cooled in the hospital morgue, or scrounge them up locally. Even assuming that the hospital staff was diligent enough to administer the required procedures to keep the body cool, it would be between 6 to 8 hours before they arrived on the scene if the patient were along the east coast near or in a major city. There are many additional factors to consider here: Can a hospital staff be expected to spend resources and time (6-8 hours) maintaining precise and constant cooling on a corpse? What sort of temperature management would/could they supply if they did? Will whatever support they DO decided to provide not to interfere with what ALCOR has to do when they begin suspension? The VPS has these advantages: The unit is very portable and contains no temperature-perishable material. It does not require any form of gasses for cooling, using instead an electrical method using battery assistance -- this means it would not be barred from transport upon airlines, and could even utilize airline power resources to maintain the patient. Because it is an electrical means of cooling using the Peltier effect, it can be controlled with high levels of precision, with sensors giving degree accurate readings that will allow cooling to be maintained at as close to freezing as safely possible. Such a device would actually be much less intensive to administer. Although ice is a common and everyday form of cooling, it can be laborious to maintain and transport even on a local level. This device will allow cooling to be administered without such messy concerns. How does it work? The VPS is a three-piece system that consists of the refrigeration unit , battery pack/powersupply, and liquid precooler. Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=17359
