Blood glucose sensor dispensing instrument having a serrated knife

Abstract

The present application relates to an intraluminal thin film medical device (100) particularly well suited for occlusion of an aneurysm, vessel side branch or dissection of a body lumen or duct, such as an artery or vein. The medical device has a thin film tube (101) capable of being longitudinally stretched by the application of mechanical energy to achieve a smaller circumferential profile, and self-expand to the pre-stretched length and diameter upon release of the mechanical energy. To assist the thin film during expansion a plurality of slots (102) are incised in the tube wall. The slots open and assist the thin film tube to longitudinally stretch, and substantially close when the thin film tube self-expands to the pre-stretched length and diameter.A sensor dispensing instrument comprises a housing, a sensor pack, a sensor, and a knife blade assembly. The sensor pack is disposed within the housing and has a sensor cavity and a protective covering. The sensor is disposed within the sensor cavity. The knife blade assembly is operably disposed within the housing and has a serrated edge for cutting the protective covering.

Description

technical field [0001] The present invention relates to a fluid monitoring system and, more particularly, to a new and improved tool for handling and cutting a fluid sensor from its housing. Background technique [0002] People with abnormal blood sugar levels are medically required to self-monitor their blood sugar levels on a regular basis. Abnormal blood sugar levels can result from a variety of causes, including diseases such as diabetes. Diabetes affects an estimated 18 million people in the United States alone. Diabetics typically monitor their blood sugar concentration levels to determine if the levels are too high or too low and if any adjustments are needed to bring the levels back into the normal range, such as adjusting insulin or other drug therapy. Failure to perform adjustment work has serious consequences. When blood sugar levels drop too low, a condition called hypoglycemia, people become restless, shaky and flustered. The patient's judgment will weaken a...

Problems solved by technology

[0010] Although the sensor tool disclosed in the 1986 patent solves many of the above-mentioned problems associated with the use of a single sensor, in some cases the straight beveled edge of the blade will rip or tear the thin foil rather than cut

This can cause thin foil debris to become dislodged and can get lodged in the nose of the tool, which can cause sensor blockage
