Embodiment Construction

[0016] Timing is of the essence in responding to certain medical conditions. For example, a patient suffering from anaphylactic shock may require drug delivery shortly after the onset of the reaction. In many cases, especially in emergency medical conditions, the person administering the drug is not a trained medical professional. Additionally, even for trained medical professionals, if the necessary medications and equipment are not located in one location, this can use up valuable time assembling the necessary tools and medicines. Thus, combining multiple pharmaceuticals in a single, easy-to-use device offers significant benefits in the treatment of life-threatening medical conditions such as anaphylaxis.

[0017] The present application describes injection devices that allow a user to administer multiple volumes of the same or different contents. The injection device may have a plurality of chambers for containing the contents prior to administration of the contents to a ...

Abstract

A multi-chamber injection device includes multiple syringes. The multiple syringes may be arrayed in a circular, linear, or other format. In some implementations, a needle, port, or similar may be shared by all the syringes in configuration that allows only one syringe to deliver contents at a time while blocking the other syringes from delivering their respective contents. In some implementations, the syringes may be all stored in the same container. One or more of the chambers of a multi-chamber injection device may be preloaded with medication. Different medications may be loaded into different chambers. The medications may be selected to treat the same medical condition.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of co-pending US Provisional Patent Application No. 61 / 801,275, filed March 15, 2013, and entitled "Multiple Chamber Injection Device." US Provisional Patent Application No. 61 / 801,275 is hereby incorporated by reference in its entirety. Background technique [0003] Drug injection is an efficient technique for delivering drugs directly into a patient's bloodstream. However, conventional syringes and other injection devices can be difficult to use and inconvenient for drug delivery, especially in cases where urgent medical conditions would benefit from rapid treatment. Accordingly, there is a need for improved injection devices. Contents of the invention [0004] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features...
