US Patent:

20130018241, Jan 17, 2013

Filed:

Dec 23, 2010

Appl. No.:

13/518452

Inventors:

Vassilios Bezzerides - Brookline MA, US
Mark Ian Neuman - Wayland MA, US

Assignee:

Childeren's Medical Center Corporation - Boston MA

International Classification:

A61B 6/00
A61B 5/0295
A61B 5/1455

US Classification:

600324, 600479

Abstract:

An apparatus for measuring capillary refill time has a measurement module containing at least two radiation sources and at least one detector configured to detect radiation from each source that interacts with and is received from a measurement region of a patient or subject. One radiation source may be characterized by a wavelength that is absorbed substantially equally by oxyhemoglobin and deoxyhemoglobin. The other radiation source may be substantially unaffected by the presence or absence of blood in the measurement region. The measurement module may be applied against a measurement region of a patient for a first time period, and the released from the measurement region for a second time period, and detected signals processed to quantitatively evaluate capillary refill time.

Assignee:

Koch-Glitsch, Inc. - Wichita KS

International Classification:

C25B 1500

US Classification:

204233, 204234, 266168, 266170

Abstract:

A modular solvent extraction plant for extracting metal from a metal are is provided. It includes a stage-wise, plug flow contactor that mixes an aqueous solution and an organic solvent solution into a mixed emulsion, a reactor to further mix the solutions, a separator for breaking up the emulsion into an aqueous solution and an organic solution, and a loaded organic coalescer that removes aqueous entrainment. It may also include a raffinate coalescer that removes organic entrainment, a second stage-wise, plug flow contactor that mixes an electrolyte solution with the organic solution from the loaded organic coalescer to form a second mixed emulsion, a second reactor, a second separator for breaking up the second emulsion, and an electrolyte coalescer. An organic scrub station may be used in place of the loaded organic coalescer. The contactors, reactors, separators, and coalescers can be mounted on movable structures.

Inventors:

MARK NEUMAN - Queens NY, US

International Classification:

Abstract:

A cervical inspection device includes a sealing body defined by an outer perimeter and being constructed for sealing placement about the vaginal introitus of a patient, the sealing body having an opening for introducing gas under pressure into the vaginal vault of the patient; and an extendable member connected to the sealing body in a region radially inwardly relative to the outer perimeter of the sealing body and being extendable in a direction transverse to the perimeter of the sealing body to form a generally tubular sheath.
