Wearable Hormone Injector Pump With Feedback Dosing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hormone delivery methods, particularly subcutaneous injections, cause large fluctuations in hormone levels leading to unwanted side effects such as mood swings, weight gain, and anxiety due to single bolus doses, and lack real-time adjustment to natural hormone cycles.
Innovation Solution
A wearable injector pump with a disposable drug reservoir and needle injection system that monitors hormone levels using sensors, adjusts hormone delivery based on real-time biomarker data, and uses predictive AI to maintain consistent hormone levels through continuous or scheduled delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If single bolus injection is used to deliver hormone therapy, then the injection dose can be administered quickly and easily, but it causes large fluctuations in hormone levels leading to unwanted side effects
Solution Approach 1:
The patent implements periodic action by delivering hormones in multiple smaller doses throughout the day rather than a single bolus injection. The pump system administers hormone therapy at scheduled intervals or in response to sensor-detected hormone level drops, maintaining stable hormone levels and avoiding the large fluctuations that cause side effects like mood swings, weight gain, and anxiety.
2Stability of the object's composition
If continuous monitoring and adjusted delivery system is implemented, then hormone levels can be maintained consistently, but the device complexity increases
Solution Approach 1:
The patent applies feedback by incorporating sensors that continuously monitor hormone levels and provide real-time data to the pump controller. When the sensor detects a drop in hormone levels, it triggers the pump to deliver an additional dose. This closed-loop feedback system maintains stable hormone levels without requiring complex manual adjustment protocols.
Solution Approach 2:
The system implements self-service by automatically detecting hormone level drops through sensors and triggering appropriate dosing responses without requiring patient intervention. The pump autonomously adjusts delivery based on sensor data, eliminating the need for patients to manually track symptoms or calculate dosages.
3Stability of the object's composition
If multiple smaller doses are delivered throughout the day, then hormone level stability is improved, but the device complexity and operational complexity increase
Solution Approach 1:
The patent merges the functions of hormone storage, pumping, and sensing into a single integrated wearable device. The reservoir, pump mechanism, and sensor system are combined in one unit that can be worn on the patient's body, simplifying the overall system architecture despite the complex delivery schedule. This integration eliminates the need for separate components and reduces operational complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The pump effectively maintains stable hormone levels by compensating for natural fluctuations and sudden drops, reducing side effects and providing discreet, continuous hormone delivery.
Implementation Method 1
The fluid reservoir utilizes the pressure on the fluid reservoir to drive fluid out of the fluid reservoir
Implementation Method 2
sensors that sense biomarkers indicative of hormone level or hormone level changes such as changes in basal body temperature, blood pressure, galvanic skin response, sweat production, heart rate, respiration variability, and presence of certain biological molecules
Data Source
AI summary
An injector pump having a fluid reservoir sealed to a length of tubing extending from the reservoir and an automatic needle injection mechanism. The fluid hormone is delivered over a continuous, extended period to provide for the delivery of replacement hormones based on the hormone fluctuations of the patient and naturally occurring hormone cycles.
