US Patent:

20160339225, Nov 24, 2016

Filed:

Jul 17, 2015

Appl. No.:

15/026455

Inventors:

- Salt Lake City UT, US
Michael A. Marshall - Herriman UT, US

International Classification:

A61M 39/12
A61M 5/162
A61M 5/142

Abstract:

A cassette for operatively connecting administration set tubing to an infusion pump includes a thumb tab having a thumb surface, and a tubing connector having an in-line occluder spaced laterally from the thumb tab. The cassette is configured such that a user's hand will cradle the cassette by pressing a thumb of the user's hand against the thumb surface and wrapping at least one finger of the user's hand around and under the thumb tab, whereby a user may apply pressure to tubing connected to the tubing connector at a location corresponding to the in-line occluder in a direction generally opposite to a direction in which the thumb is pressed against the thumb surface, thereby bypassing the in-line occluder and allowing flow through the tubing.

Inventors:

- Salt Lake City UT, US

Michael Elwood - Farmington UT, US

International Classification:

A61M 5/50
A61M 5/142
A61M 5/172

Abstract:

An infusion pump has an optical detection system for determining whether or not a cassette of an administration tubing set is properly loaded in the pump. Operation of the pump may be enabled or disabled based on a determination of the cassette detection system. The optical cassette detection system includes a light emitter directing a light beam along an optical axis to a corresponding light detector aligned on the optical axis. The cassette detection system also includes a tab carried by the cassette and arranged such that when the cassette is properly loaded in the pump, the tab intersects the optical axis and blocks at least a portion of the light beam from reaching the detector. The detector signal is evaluated by signal evaluation electronics to determine if the detector signal level is below a predetermined threshold, indicating presence of the cassette.

International Classification:

A61M 5/50
A61M 5/142

Abstract:

An infusion pump has an optical detection system for determining whether or not a cassette of an administration tubing set is properly loaded in the pump. Operation of the pump may be enabled or disabled based on a determination of the optical detection system. The optical cassette detection system includes a light emitter and a corresponding light detector on non-coincident emission and detection axes, and at least one optical element carried by the cassette. When the cassette is properly loaded in the pump, light from the emitter is redirected by the optical element from the emission axis to the detection axis for receipt by the detector, which registers an increased signal level. The detector signal is evaluated by signal evaluation electronics to determine if the detector signal level is above a predetermined threshold, indicating presence of the cassette.

International Classification:

A61M 5/50
A61M 5/142

Abstract:

An infusion pump has an optical cassette detection system for determining whether or not a cassette of an administration tubing set is properly loaded in the pump. Operation of the pump may be enabled or disabled based on a determination of the cassette detection system. The cassette detection system includes a light emitter and a corresponding photosensitive detector aligned along an optical axis, and window carried by the cassette. When the cassette is properly loaded in the pump, a light beam from the emitter enters the window, where a portion of the beam is absorbed and another portion of the beam is transmitted for receipt by the detector. The detector signal is evaluated by signal evaluation electronics to determine if the cassette is loaded. The determination may be based on an expected attenuation of the light beam corresponding to a predetermined light absorptance property of the window.

Abstract:

An infusion pump has an optical cassette detection system for determining whether or not a cassette of an administration tubing set is properly loaded in the pump. Operation of the pump may be enabled or disabled based on a determination of the cassette detection system. The cassette detection system includes a light emitter and a corresponding photosensitive detector, and a window carried by the cassette that includes a fluorophore. When the cassette is properly loaded in the pump, an excitation light beam from the emitter enters the window and excites the fluorophore, causing emission light in a wavelength band distinct from that of the excitation beam to be transmitted out of the window for receipt by the detector. The detector signal is evaluated by signal evaluation electronics to determine if the signal level is above a predetermined threshold, indicating the cassette is loaded.
