Embodiment Construction

[0030] This article describes a convenient, inexpensive device and method for delivering fluid to a patient and detecting leakage of fluid from an infusion set connected to a pump assembly. It will be appreciated that the principles described herein are also applicable to detecting leakage of insulin from delivery devices such as infusion sets and / or insulin patch pumps. Colorless insulin may leak from the infusion or injection site located between the outer surface of the patient's skin and the bottom of the insulin infusion set or insulin patch pump, which often makes insulin leakage a problem for the patient before the insulin leaks too much can not be seen.

[0031] Insulin stabilizers in commercially available insulins are electrically active such that the stabilizers are readily oxidized when a voltage is applied. This property makes insulin stabilizers suitable for detection by electrochemical sensors. Commonly used insulin stabilizers include m-cresol and phenol.

Abstract

An insulin delivery device (10) includes a cannula (40) for delivering insulin to a patient at an infusion site, a pump assembly (30), and a valve (36) for controlling the flow of insulin. A removableleak detector unit (28) is coupled to the delivery device for sensing and detecting leakage of insulin at the infusion site. The leak detector unit (28) has electrodes (56) positioned for contactingthe insulin leaking from the infusion site, a sensing electrical circuit (54) and a power source (58) for operating the leak detector unit. The removable leak detector unit (28) has an electrical contact (62) for mating with an electrical contact (64) of the delivery device for electrically and operatively connecting the leak detector unit (28) to the delivery device. The leak detector unit (28) sends a signal to the pump assembly (30) and / or valve (36) to stop the flow of insulin when leakage is detected at the infusion site.

Description

[0001] This application claims priority to US Provisional Application Serial No. 62 / 488,005, filed April 20, 2017, which is hereby incorporated by reference in its entirety. technical field [0002] The invention relates to a delivery device with a leak detection unit. The invention also relates to an infusion set or patch pump assembly for delivering a drug to a patient, wherein the infusion set or patch pump assembly has a removable leak detection unit, The leak detection unit controls the flow of fluid in the event of a leak from the infusion site. Background technique [0003] There are two main modes of daily insulin therapy. The first mode includes syringes and insulin pens. These devices are simple to use and relatively inexpensive, but they require needle sticks for each injection, usually three to four times a day. The second mode involves insulin infusion therapy with an insulin pump. Infusion pumps, although more complex and expensive than syringes and pens, o...
