Multi-chamber Injection Device with Shared Needle for Rapid Medication Delivery

Solution Overview

Problem

Conventional injection devices are cumbersome and inconvenient for rapid administration of multiple medications during emergent medical conditions, particularly when not all necessary equipment and medications are readily available.

Innovation Solution

A multi-chamber injection device with multiple cylindrical chambers arranged in a circular, linear, or other format, allowing preloading of different medications in each chamber, with a shared needle or outlet mechanism that enables sequential administration of contents, providing redundancy and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate syringes are used to administer multiple medications, then medication variety is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:

Improvemedication varietyVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate syringes into a single integrated multi-chamber injection device. Multiple chambers are housed within one device body, sharing common components such as the plunger rod, trigger mechanism, and needle assembly. This merging approach maintains the ability to administer multiple different medications while reducing the overall complexity of managing multiple separate devices.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The multi-chamber injection device is designed as a universal platform that can accommodate multiple different medications in its various chambers. The device structure allows each chamber to be independently filled with different medications while sharing common operational mechanisms, making the device adaptable to various treatment protocols and medication combinations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

3Device complexity

If conventional syringes are used for drug delivery, then simplicity of device structure is improved, but treatment speed and convenience deteriorate

Engineering Contradiction:

Improvesimplicity of device structureVSAvoidtreatment speed

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent combines multiple separate syringes into a single integrated multi-chamber injection device. Multiple chambers are housed within one device body, sharing common components such as the plunger rod, trigger mechanism, and needle assembly. This merging approach maintains the ability to administer multiple different medications while reducing the overall complexity of managing multiple separate devices.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device is pre-loaded with multiple medications in separate chambers before use. This preliminary preparation eliminates the need to manually prepare and switch between multiple syringes during emergent treatment, enabling rapid sequential administration of different medications through a single integrated device.

Inventive Principle:

AI summary

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.
