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

Embodiment Construction

[0038] figure 1 5 are various views of an embodiment of an injection device made in accordance with the present invention, in figure 1 Through Fig. 5, the same elements are given the same reference numerals. The injection device comprises a guide port along a guide axis and an injection port along an injection axis, wherein the injection axis and the guide axis are non-collinear. In this embodiment, the injection axis is at an angle to and intersects the guide axis.

[0039] figure 1 is a perspective view of an injection device 100 comprising a body 110 and a patch 120 attached to the body 110 . Patch 120 may be used to adhesively attach injection device 100 to a patient (not shown). The body 110 has a port face 112 and a guide port 130 and an injection port 140 on the port face 112 . Guide port 130 is used to place the delivery tube subcutaneously in the patient. Injection port 140 is used by a patient to inject a therapeutic agent, which as defined herein may be any...

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.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of and claims priority to U.S. Patent Application No. 14 / 052,929 filed October 14, 2013, entitled "Therapeutic Agent Injection Device" The entire content of the application is incorporated herein by reference. technical field [0003] The technical field of the content disclosed herein is personal medical system, specifically on-body injector and its usage method. 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 ...
