Problems solved by technology

Leaks at the infusion site may go unnoticed by the patient and may result in high blood sugar levels
Infusion pumps typically dispense insulin in small volumes over prolonged periods of time, so that leaks often go unnoticed by the patient for long periods of time, which can lead to inappropriate dosing

Embodiment Construction

[0028] The present invention relates to a fluid or drug delivery device, such as a fluid delivery device or an insulin delivery device, having a leak detection system. The present invention particularly relates to fluid delivery devices having a leak detector that provides a visual indication of a leak at an infusion site. The present invention also relates to a fluid delivery device for delivering a fluid comprising an active agent to a patient. The fluid delivery device is typically a drug delivery device used to deliver a drug, such as insulin. In this disclosure, an infusion site may be used interchangeably with an infusion site or delivery site on a patient to deliver a substance to the patient.

[0029] Reference is made to various embodiments of the present invention, which are illustrated in the drawings, wherein like reference numerals indicate like elements throughout. The embodiments described here illustrate the present invention by referring to the drawings, but...

Abstract

A delivery device such as an infusion set or patch pump is configured for delivering a pharmaceutical agent, such as insulin, to a patient. The infusion set or patch pump has a bottom surface pH indicator capable of producing a color change upon contact with the pharmaceutical agent. The pH indicator in one embodiment is bromothymol blue that is able to exhibit a color change when contacting an insulin solution to produce a rapid visually detectable color change.

Description

technical field [0001] The present invention relates to a fluid delivery device having leak detection means capable of detecting leaks at an infusion site or delivery site on a patient. In one embodiment, the fluid delivery device is an insulin infusion set or patch pump that exhibits a visible color change in response to a leak at the infusion site or delivery site. Background technique [0002] There are two main approaches to daily insulin therapy in patients with diabetes. The first method involves syringes and insulin pens. These devices are simple to use and relatively low cost, but they require needle sticks for each infusion, typically three to four times per day. The second method involves insulin infusion therapy, which uses an insulin pump. Infusion pumps, while more complex and expensive than syringes and pens, offer the advantages of continuous insulin infusion through a cannula (eg, an infusion cannula), precision dosing, and programmable delivery protocols....
