Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual administration of large volume pharmaceutical doses requires careful manual dexterity and sustained pressure, leading to inefficiency and discomfort for healthcare providers.
Innovation Solution
A reusable injection aid with a housing, actuation assembly, and toggle mechanism that allows for automatic delivery of medicament at a constant flowrate, enabling initiation, pause, and resumption of the injection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual injection is used to deliver large volume pharmaceutical doses, then the healthcare provider can control the delivery rate, but it requires sustained physical pressure and manual dexterity leading to discomfort and inefficiency
Solution Approach 1:
The injection device enables self-service by automatically delivering the pharmaceutical dose without requiring continuous manual manipulation. The mechanism uses a spring-loaded plunger that automatically pushes the medication through the needle at a controlled rate, allowing the healthcare provider to simply activate the device and then observe the automatic injection process.
Solution Approach 2:
The patent replaces the manual mechanical system with an automated mechanical system. Instead of requiring the healthcare provider to manually push and control the injection, the device uses an automated plunger mechanism with a spring and latch system that automatically controls the injection rate and duration, substituting human manual control with a mechanical automation system.
2Ease of operation
If manual injection is used for large volume doses, then the healthcare provider can adjust the delivery speed, but it requires all the health care provider's attention and time reducing clinic efficiency
Solution Approach 1:
The device incorporates preliminary action through the pre-loaded spring mechanism and calibrated plunger system. The injection parameters (rate, duration, volume) are predetermined and built into the device mechanism before use, eliminating the need for the healthcare provider to continuously monitor and adjust delivery parameters during administration.
Solution Approach 2:
The automated mechanism performs the time-consuming monitoring and adjustment tasks automatically. Once activated, the device self-regulates the injection process without requiring the healthcare provider's continuous attention, allowing them to perform other tasks during the administration period.
3Ease of operation
If manual injection is used to deliver large volumes, then the healthcare provider can control the flowrate, but sustained pressure causes hand cramps and physical strain
Solution Approach 1:
The patent substitutes the healthcare provider's manual mechanical action with an automated mechanical system. The spring-loaded plunger mechanism automatically generates and maintains the necessary pressure to deliver the medication, completely eliminating the physical strain and hand cramps that result from sustained manual pressure application.
Solution Approach 2:
The device performs the physically demanding task of maintaining sustained pressure automatically. The internal spring mechanism continuously supplies the force needed to push the medication through the needle without requiring the healthcare provider to exert or maintain physical pressure, thereby eliminating physical strain and discomfort.

AI summary
An injection aid includes a housing, an actuation assembly, and a toggle. The housing can be adapted to receive a container. The container can include a medicament chamber and a plunger movable relative to the medicament chamber to dispense medicament out of the medicament chamber. The actuation assembly can be adapted to move the plunger relative to the medicament chamber. The toggle can be movable from a ready configuration to a firing configuration whereby the actuation assembly urges the plunger to move. The toggle can be movable from the firing configuration to the ready configuration whereby the plunger is fixed relative to the housing to pause dispensing the medicament. The toggle can be moveable from the ready configuration to the firing configuration to resume dispensing medicament from the medicament chamber.
