Skin-Contact Extraction Device with Automatic Activator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for obtaining blood or other fluids from subjects, such as phlebotomy, are complex and require specialized training, making them difficult to perform in non-medical settings and often necessitate substantial equipment.
Innovation Solution
A device with a support structure for skin application, featuring a fluid transporter or substance transfer component, and an activator that can insert the component into the skin automatically or upon activation, allowing for the extraction or delivery of fluids without simultaneous subject activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional phlebotomy equipment and methods are used, then reliable blood extraction is achieved, but device complexity and training requirements increase substantially
Solution Approach 1:
The device is segmented into distinct functional modules: a support structure for skin application, a fluid transporter or substance transfer component for fluid movement, and an activator for triggering the extraction process. This modular segmentation allows each component to perform its specific function reliably while reducing overall system complexity and making the device easier to manufacture and train on.
2Quantity of substance
If traditional phlebotomy methods are used, then sufficient blood sample is obtained, but practitioner training time and complexity increase
Solution Approach 1:
The device incorporates an activator that can automatically trigger the fluid transporter to deliver the blood sample to a collection container or analysis device, reducing the need for practitioner skill in manual blood transfer. The support structure is designed for simple application to the skin, and the activator handles the complex coordination of sample extraction and transfer, making the overall process easier to operate and train on while maintaining sufficient sample quantity.
3Ease of operation
If manual activation by subject is required, then subject control is maintained, but extraction timing precision decreases
Solution Approach 1:
The device is designed with the support structure already positioned and ready for skin application, and the fluid transporter pre-loaded with necessary components. Upon activation (either manual or automatic), the extraction process occurs rapidly and precisely. The activator is pre-configured to trigger the exact sequence of operations needed, ensuring timing precision while maintaining subject control through the activation mechanism.

AI summary
The present invention generally relates to systems and methods for delivering and/or receiving a substance or substances such as blood, from subjects, e.g., from the skin and/or from other tissues of the body. In some cases, the device may contain a substance transfer component such as needles or microneedles, which can be inserted into the skin or another organ to deliver and/or receiving fluid or other substances from the subject. In some embodiments, the device may include an activator constructed and arranged to insert one or more substance transfer components into the skin or other organ. In certain cases, the device may also include a storage chamber for receiving a fluid received from the subject.
