Improved auto-injector

Abstract

An injector such as a needle-type autoinjector having a flexible flange disposed at an injection end of the injector for stretching or pinching the skin of the injection site. The flexible flange may be removably attached to the injector or integrated into the injector during manufacturing. Further, an injector having a palm button disposed at an activation end of the injector for activating an injection cycle of the injector. The palm button may be removably attached to the injector or integrated into the injector during manufacturing. Still further, a holding device for one-handed operation of an injector, the holding device having a sleeve and at least one hand rest coupled to the sleeve, the sleeve and hand rest providing ergonomic holding and operation of the injector. Still further, autoinjector needle shield having an enlarged, rounded lip for contacting the skin at the injection site.

Description

technical field [0001] The present disclosure relates to an autoinjector device. More particularly, the present disclosure relates to an autoinjector device with skin stretching and pinching capabilities, an ergonomic autoinjector grip, and other ergonomic improvements for autoinjectors. Background technique [0002] An auto-injector (AI) device is held against the body to administer the drug product while the injection needle penetrates the skin. While gripping the autoinjector, the user applies a downward motion against the skin to trigger the autoinjector. The user then presses the button, causing the needle to inject and the stop to push the drug down into the skin. [0003] During needle insertion and plunger movement, the contact surface / surface area between the user's skin and the physical area of ​​the autoinjector touching the skin (and surrounding the needle) must remain in place to prevent the autoinjector and / or needle from Slip or motion on the surface of the...

AI Technical Summary

Problems solved by technology

[0005] During the act of placing the autoinjector onto the injection site and triggering the autoinjector, users have found the following problems: 1) distracting, letting go of stretched or pinched skin, and attempting to maneuver the autoinjector into place; 2 ) release of stretched or pinched skin in order to grasp the autoinjector with both hands due to lack of substantial hand strength or dexterity; and 3) premature removal of the injection device before completion of the injection

Some patients did not apply the required trigger force, so the auto-injector could not be programmed and ready for injection
