Continuous glucose monitor sensor tube
According to the US CDC National Diabetes Fact Sheet, 2011, diabetes affects 8.3-percent of the U.S. population, or a staggering 25 million people. Of those diagnosed with diabetes, (type 1 and type 2) 26-percent take either insulin or a combination of insulin and oral medication. This debilitating disease is growing rapidly all over the world; Western dietary habits and obesity are leading risk factors for diabetes.
Blood Glucose Testing Devices
Short term and long term implantable sensors, both minimally-invasive and non-invasive, measure glucose levels directly or indirectly by a variety of methods. Continuous glucose monitoring permits frequent measurement of glucose levels without patient intervention, unlike traditional glucose testing that requires multiple needle sticks each day.
Laser-drilled holes in an infusion set
These polymer-based sensors made in sheet, wire, cable, catheter or fiber optic format, all have a common requirement to regulate the flow of blood, perspiration, optical fluorescence with apertures or windows with tolerances as small as a few microns. Since the absolute signal produced is proportional to the actual sensor area, laser micro-machining is a natural fabrication technology due to its high precision and repeatability.
The traditional method of giving insulin is by subcutaneous injection such as a syringe and needle, pens and needle-free injectors. Insulin pumps are a new trend in insulin delivery as they are compact, wearable (and disposable) electronically-controlled delivery devices. Laser machining of the infusion holes for infusion sets is a natural application of laser technology due to the precise control of flow.
