Automated Injection System with Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency situations, patients often require immediate administration of fluids and medications intravenously or intraosseously, but there is a need for a device that can quickly and effectively provide treatment, especially when medical facilities are inaccessible.
Innovation Solution
An injection system with a brace that includes a needle, biosensors, and a computing device to automatically or manually control the needle's extraction and retraction, fluid administration, and dosage, which can be secured to a body part using an adjustable fastener and may be carried and deployed by an unmanned vehicle, featuring communication capabilities and sensors for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual injection methods are used in emergency situations, then simplicity and ease of operation are maintained, but speed and accuracy of treatment administration are insufficient
Solution Approach 1:
The injection system performs self-positioning using sensors to detect bone landmarks and automatically determines the injection site, eliminating the need for manual positioning by medical personnel. The system self-adjusts based on real-time sensor feedback to ensure accurate needle placement.
Solution Approach 2:
The patent replaces manual mechanical positioning with an automated system using sensors (optical, acoustic, or tactile) to detect anatomical landmarks and calculate the optimal injection position. This substitution of mechanical manual operation with sensor-based automation resolves the contradiction between speed and complexity.
2Measurement precision
If automated needle extraction and retraction is implemented, then precision and control are improved, but device complexity increases
Solution Approach 1:
The system continuously monitors needle position using sensors and provides real-time feedback to the control mechanism. This feedback loop allows the system to adjust the needle extraction and retraction automatically, ensuring precise placement while maintaining relatively simple control through closed-loop control algorithms.
3Reliability
If biosensors and computing devices are added to the brace, then real-time monitoring and automated control are achieved, but weight and device complexity increase
Solution Approach 1:
The brace is designed as a multi-functional device that combines structural support, sensor integration, automated needle control, and fluid administration into a single system. By making the brace universal and multi-functional, the patent reduces the need for separate devices, thereby minimizing overall weight while maintaining high reliability through integrated real-time monitoring and control.

AI summary
An injection system has a brace; a needle inside the brace in a retracted position; a mechanism operable to drive the needle from the retracted position to an extracted position; and a fluid dispenser fluidly connected to the needle. An adjustable fastener secures the brace to a body part. The injection system further includes an unmanned vehicle to carry and deploy the brace; a speaker; a microphone; a memory storing an application; and a processor which executes the application to cause the speaker and microphone to operate as a communication device and/or to cause the mechanism to extract the needle, cause the injection system to administer a dosage through the needle, and cause the mechanism to retract the needle. One or more sensors detect a position or pressure of the brace with respect to a body part. The needle may be an intravenous needle or an intraosseous needle.
