Assessment Of Concentration Of Inhalational Compounds In The Brain
US Patent:
6579511, Jun 17, 2003
Filed:
Mar 16, 2001
Appl. No.:
09/811316
Inventors:
Chung-Yuan Lin - Chicago IL 60637
Assignee:
Chung-Yuan Lin - Chicago IL
International Classification:
A61K 4900
US Classification:
424 91, 600529, 600544
Abstract:
This invention directs to a method of assessing the concentration of an inhalational compound in the brain of a subject. The method includes administering a gas containing the compound into a subject to fill the pulmonary functional residual capacity, which is defined as the remaining lung volume at the end of an unforced respiration. The method also includes measuring an inspired compound concentration (C ) and an expired compound concentration (C ) after having filled the functional residual capacity with the gas. Therefore, a mixed venous compound concentration (C ) can be assessed based on the formula C =[C (M-1)+C â²]/M, in which M is an alveolar membrane factor for the compound; and a brain compound concentration (C ) can be assessed based on the formula C =(C +C )/2.
Anesthetic Applicator With A Temperature Humidity Regulating Capability
US Patent:
6125847, Oct 3, 2000
Filed:
Oct 22, 1997
Appl. No.:
8/955800
Inventors:
Chung-Yuan Lin - Chicago IL
International Classification:
A61M 1600
US Classification:
12820417
Abstract:
An anesthetic applicator with a temperature/moisture regulating capability is provided. The anesthetic applicator includes: means for supplying anesthetic; an inner duct, connected to the anesthetic supplying means, for conducting the anesthetic to the patient; means for recycling the exhaled breath from the patent so that the recycled anesthetic can be resupplied via the inner duct to the patient; an outer duct sleeving the inner duct in such a manner that a passage is formed between the outer duct and the inner duct; and means for supplying a stream of heated fluid such as heated air or water to flow through the passage between the outer duct and the inner duct. The recycling means includes: an exhaled-gas duct connected to receive the exhaled breath from the patient; an exhaling valve connected to the outlet of the exhaled-gas duct; a carbon-dioxide collector for filtering out the carbon dioxide contained in the exhaled breath of the patient; and means for conducting the exhaled gas from the carbon-dioxide collector to the inner duct so that the anesthetic gas can be recycled for use on the patient. This anesthetic applicator is capable of regulating the anesthetic being supplied to the patient within suitable temperature and humidity ranges. This allows the supplied anesthetic gas to adjust to the temperature/humidity conditions inside the patient's body, so that undesirable consequences to the patient can be avoided.

Assessment Of Concentration Of Inhalational Compounds In The Brain
US Patent:
7001339, Feb 21, 2006
Filed:
Apr 29, 2003
Appl. No.:
10/425360
Inventors:
Chung-Yuan Lin - Chicago IL, US
International Classification:
A61B 5/08, A61K 49/00
US Classification:
600532, 600529, 424 91
Abstract:
This invention directs to a method of assessing the concentration of an inhalational compound in the brain of a subject. The method includes administering a gas containing the compound into a subject to fill the pulmonary functional residual capacity, which is defined as the remaining lung volume at the end of an unforced respiration. The method also includes measuring an inspired compound concentration (C) and an expired compound concentration (C) after having filled the functional residual capacity with the gas. Therefore, a mixed venous compound concentration (C) can be assessed based on the formula C=[C(M−1)+C]/M, in which M is an alveolar membrane factor for the compound; and a brain compound concentration (C) can be assessed based on the formula C=(C+C)/2.

Appl. No.:
10/900158
Inventors:
Chung-Yuan Lin - Chicago IL, US
International Classification:
