Filed:

Nov 7, 2005

Appl. No.:

11/268687

Inventors:

Thomas Francis Kappel - St. Louis MO, US
Mark Dennis Worley - Imperial MO, US

Assignee:

Nellcor Puritan Bennett LLC - Boulder CO

International Classification:

A61M 1/00

US Classification:

604126

Abstract:

A vent system for an infusion drip chamber is provided according to the invention. The vent system includes an automatic air eliminator communicating with an interior and an exterior of the infusion drip chamber. The automatic air eliminator is capable of automatically venting air from the infusion drip chamber in a substantially continuous manner. The vent system further includes a mechanical air eliminator communicating with the interior and the exterior of the infusion drip chamber. The manual air eliminator is capable of mechanically venting air from the infusion drip chamber at discrete time intervals.

Filed:

Jul 7, 2011

Appl. No.:

13/808721

Inventors:

Mark D. Worley - Imperial MO, US
Michael R. Mahoney - Wentzville MO, US

International Classification:

B01F 15/02

US Classification:

366137, 222 71, 141105, 366189

Abstract:

A slurry dispensing system () is disclosed. A peristaltic pump () may direct a flow of slurry out of a horizontal mixer () to a slurry dispenser (). This slurry dispenser () may be operated on a programmed manner by a controller () to dispense slurry into a container (). Both a bypass valve () and a dispensing valve () of the slurry dispenser may be opened/closed on a programmed basis by the controller () to deliver slurry to a container (), such as a glass column. Slurry may be intermittently directed into a metering chamber () of the slurry dispenser (), while the remainder of the slurry being directed into the slurry dispenser () may be recirculated back to the horizontal mixer ().

Inventors:

International Classification:

B01F 9/06

US Classification:

366136, 366228

Abstract:

A horizontal mixer () is disclosed. Multiple blades () are affixed to and rotate with a tumbler () of the mixer (). These blades () extend within an interior mixing chamber () and are center-angled so as to promote a desirable mixing action within this chamber () (e.g. so as to fold a slurry within the chamber () onto itself). One characterization is that the blades () are oriented so as to direct a flow toward a common outlet region () within the tumbler () throughout at least a certain rotational angle. The mixer () is particularly suited for realizing a desirable homogeneity of particles within a slurry from which radioisotopes may be produced.
