Appl. No.:

13/510450

Inventors:

Sung Kwon Cho - Pittsburgh PA, US
William Walker Clark - Wexford PA, US

International Classification:

G01N 27/30
A61B 5/145
F17D 1/08

US Classification:

204409, 204433, 137561 A, 137 13, 600345

Abstract:

A pH sensor includes an enclosed fluidic channel, an electrolyte solution within the fluidic channel, a first electrode exterior to the fluidic channel, a second electrode within the fluidic channel, a liquid junction extending between the fluidic channel and an exterior of the fluidic channel. The liquid junction is adapted to provide fluid connection between the electrolyte solution within the fluidic channel and an exterior of the fluidic channel. The pH sensor further includes a fluidic switch or fluidic controller in operative connection with the liquid junction to control whether the liquid junction provides fluid connection between the electrolyte solution within the fluidic channel and the exterior of the fluidic channel.

Assignee:

University of Pittsburgh - Of the Commonwealth System of Higher Education - Pittsburgh PA

International Classification:

A61B 5/0215
B81B 3/00
B81C 1/00

Abstract:

A diaphragm-based sensor includes a deflectable diaphragm, a base layer opposite the diaphragm, and a corrugated wall extending between the diaphragm and the base layer. The diaphragm is suspended over a cavity enclosed by the diaphragm, the base layer and the corrugated wall. The diaphragm includes a first electrode and the base layer includes a second electrode such that a capacitance between the first and second electrodes changes when the diaphragm is deflected relative to the cavity.

International Classification:

A61B 17/12
G06K 7/10

Abstract:

The present disclosure concerns embodiments of an implantable perfusion device that can be implanted in an injured blood vessel to control bleeding without occluding the vessel. In one specific implementation, the perfusion device can be implanted percutaneously into a patient's descending aorta to control bleeding at the site of a ruptured portion of the aorta (known as torso hemorrhage) while still allowing for the antegrade flow of blood from a location upstream of the ruptured portion of the aorta to a location downstream of the ruptured portion of the aorta. The perfusion device can be left inside the patient as the patient is transported to a medical facility where the injury can be repaired. Following repair of the vessel, the perfusion device can be withdrawn from the patient.

International Classification:

B01L 3/00
G01N 27/447
G01N 27/06

Abstract:

A digital microfluidic system includes a substrate, a plurality of electrode sets provided on the substrate, wherein each of the electrode sets includes two co-planar interdigitated finger electrodes, and a driving circuit including an AC/DC voltage source and a controller. Each of the electrode sets is individually addressable by the driving circuit under control of the controller such that an AC/DC voltage generated by the AC/DC voltage source may be selectively provided to one or more of the electrode sets. Also, an anti-biofouling electrode for a digital microfluidic system includes an electrode layer, and a slippery liquid infused porous surface structure provided on the electrode layer.
