US Patent:

20050238732, Oct 27, 2005
Filed:

Nov 30, 2004
Appl. No.:

11/001249
Inventors:

Kaitao Lu - Irvine CA, US
Peter Zhu - Irvine CA, US
International Classification:

A61K031/11
A61K033/00
US Classification:

424717000, 514699000
Abstract:

Disclosed herein are methods of sealing germicidal bicarbonate solutions in containers. In one aspect, a method may include introducing water, bicarbonate, and a germicide that is more stable at a pH of 7 than at a pH of 8 into a container, replacing at least a portion of a gas in the container with carbon dioxide, and sealing the container after said introducing the water, the bicarbonate, and the germicide, into the container, and after said replacing the gas. Sealed containers having the germicidal bicarbonate solutions are also disclosed.

US Patent:

20070004808, Jan 4, 2007
Filed:

Jun 29, 2005
Appl. No.:

11/172343
Inventors:

Peter Zhu - Irvine CA, US
Bobby Brewer - Lewis Center OH, US
Kaitao Lu - Irvine CA, US
International Classification:

A61K 31/11
US Classification:

514699000, 568426000
Abstract:

Methods of forming germicidal aromatic dialdehydes by hydrolyzing acetals are disclosed. Compositions and kits including both germicidal aromatic dialdehydes and acetals that are capable of being converted to germicides are disclosed. In one aspect, an acetal may be converted to germicide gradually in a deployed germicidal solution to accommodate for loss of the germicide or otherwise to modify the germicidal efficacy of the deployed germicidal solution.

US Patent:

20220401603, Dec 22, 2022
Filed:

Jun 29, 2022
Appl. No.:

17/852898
Inventors:

- Schaffhausen, CH
Nick N. Nguyen - Silverado CA, US
Kaitao Lu - Irvine CA, US
International Classification:

A61L 2/18
A61B 1/12
A61B 1/00
A61L 2/24
G01N 21/80
A61B 90/70
G01N 31/22
Abstract:

A medical instrument processor includes an enclosure, a liquid distribution system, and a disinfectant concentration measuring subsystem. The enclosure is configured to hold a medical instrument. The liquid distribution system is configured to deliver a disinfection solution to a medical instrument within the enclosure. The liquid distribution system has a liquid outlet. The disinfectant concentration measuring subsystem includes a first mixing chamber in fluid communication with the liquid outlet, a pump that is configured to simultaneously pump the disinfection solution and the reagent solution into the first mixing chamber, and a concentration analysis assembly that is operable to determine a concentration of disinfectant in a sample solution that is output from the first mixing chamber. The reservoir is in fluid communication with the first mixing chamber.
