On-body injector and method of use

Abstract

An on-body injector and method of use including an on-body injector for use with an injection device. The on-body injector includes a bolus reservoir; a bolus injection needle in fluid communication with the bolus reservoir, the bolus injection needle having a bolus injection needle tip aligned with the injection port, the bolus injection needle being slideably biased away from the injection port to define a gap between the bolus injection needle tip and the injection port; and a button operably connected to the bolus injection needle to slide the bolus injection needle along the injection axis. The button is operable to advance the bolus injection needle tip to close the gap and advance the tip into the injection port. The button is further operable to advance a plunger through the bolus reservoir to deliver a predetermined bolus volume to the patient through the injection flow path.

Background technique [0004] Some medical conditions or diseases require patients to receive intermittent subcutaneous injections of drugs or therapeutic agents to maintain the medical condition or disease under control. Multiple daily injections (MDI) may be required. One such medical condition is diabetes, in which insulin injections are required to regulate blood sugar. In the United States, approximately 26 million people, or approximately 8% of the US population, have diabetes. This proportion is expected ...

AI Technical Summary

Problems solved by technology

While injection ports have been developed with dedicated reservoirs that allow bolus injections, such injection ports require maintaining a continuous fluid path and risk inadvertent bolus injections

Although these problems can be corrected with dedicated electronic insulin pumps, many patients are unwilling or unable to use dedicated insulin pumps due to cost and complexity

For patients, such systems also present other barriers, such as not being able to choose different treatment options based on specific daily needs or daily activities
