Solution Overview

Problem

Current injection methods for multiple injections are inefficient, inconsistent, and time-consuming due to manual administration, leading to variable injection depth and distribution, which can be painful and reduce effectiveness.

Innovation Solution

A multiple syringe automated injector with a base portion, control section, articulation element, and pusher plate, along with a controller and power element, allows for simultaneous and uniform dispensing of fluid from multiple syringes, with an end protector for precise needle placement and automated operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple injections are administered manually by hand, then each injection can be individually controlled, but the process becomes time-consuming and inconsistent in injection depth and distribution

Engineering Contradiction:

Improveinjection depth consistencyVSAvoidinjection session duration

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The device divides the injection system into multiple independent syringe units (first syringe, second syringe, etc.) that can be simultaneously actuated. Each syringe is independently positioned and controlled, allowing multiple injections to be administered in parallel rather than sequentially, thereby reducing total injection time while maintaining consistent depth through uniform pusher plate movement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces manual mechanical injection administration with an automated articulation element and pusher plate mechanism. The articulation element automatically moves the pusher plate to depress plungers of multiple syringes simultaneously, eliminating manual operation inconsistencies and ensuring uniform injection depth across all syringes while significantly reducing the time required for multiple injections.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If multiple injections are administered manually, then flexibility in administration is maintained, but injection distribution and depth become inconsistent

Engineering Contradiction:

Improveinjection administration flexibilityVSAvoidinjection distribution uniformity

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The device merges multiple syringe administration functions into a single integrated platform with a common pusher plate and articulation element. This ensures that all syringes are actuated simultaneously with identical force and displacement, guaranteeing uniform injection distribution and depth while maintaining operational simplicity through centralized control.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The articulation element and pusher plate mechanism serve as universal components that can actuate any number of syringes configured in the device. The system is designed to accommodate multiple syringes of potentially different sizes and configurations while ensuring each receives identical actuation force, providing both flexibility in setup and precision in execution.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If manual injection administration is used, then device complexity is low, but productivity and consistency of multiple injections are reduced

Engineering Contradiction:

Improveinjection administration speedVSAvoidautomated injector structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The device incorporates a movable pusher plate actuated by an articulation element that can dynamically adjust its position to accommodate different syringe configurations and injection depths. This dynamic mechanism allows the system to maintain high productivity across various injection scenarios without requiring complete redesign, balancing automation capability with structural efficiency.

Inventive Principle:

AI summary

Provided herein are an injection device and a method of injecting a patient. The injection device includes a base portion including a body section and a control section, at least one bracket secured to the body section, an articulation element secured to the control section, and a pusher plate coupled to the articulation element, wherein the articulation element moves the pusher plate with respect to the base portion. The method includes positioning at least two syringes in the injection device, placing an injection end of the injection device in contact with an injection site on the patient, and activating the articulation element, wherein activating the articulation element moves the pusher plate towards the at least two syringes, depressing a plunger and dispensing a fluid from the at least two syringes.
