Needle Magnetizer Sleeve With Depth Gauge for Sterile Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for magnetizing tissue-penetrating medical devices, such as needles, are inconsistent and risk damaging the device or leading to contamination, as clinicians struggle to visualize and accurately magnetize needles of varying lengths without additional risks or equipment costs.
Innovation Solution
A sleeve member with a graduated injection depth gauge provides a protective closure for the needle, ensuring consistent magnetization by indicating the correct insertion depth, and a magnetizer design with movable segments adjusts to accommodate needles of different lengths, ensuring precise magnetization without additional risk or equipment costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a needle cover is used during magnetization to protect the needle tip and maintain sterility, then the needle is protected from damage and contamination, but the practitioner cannot see the needle tip or length to be magnetized, resulting in inconsistent magnetization depth and potential needle damage
Solution Approach 1:
A transparent or translucent cover is introduced as an intermediary between the practitioner and the needle. This cover allows visual observation of the needle tip and length while still providing protective closure during magnetization, resolving the contradiction between protection and visibility
Solution Approach 2:
The cover incorporates visual indicators such as colored bands, markings, or transparent sections that allow the practitioner to see the needle tip position and determine the correct magnetization depth, enabling precise measurement while maintaining protection
2Ease of manufacture
If manual magnetization is performed by the clinician, then the process is simple and requires no additional equipment, but the magnetization is inconsistent due to variability in insertion depth, speed, and centering
Solution Approach 1:
The magnetizer device is designed to perform the magnetization function automatically when the needle is inserted into it. The device self-regulates the magnetization process, eliminating the need for the clinician to manually control insertion depth, speed, and centering, thereby ensuring consistent results while maintaining ease of use
Solution Approach 2:
The manual mechanical process of magnetization by the clinician is replaced with an automated magnetic field application system. The magnetizer device generates and applies the magnetic field automatically, replacing the variable human mechanical action with a controlled electromagnetic or permanent magnetic field system
3Adaptability or versatility
If the magnetizer is designed to accommodate needles of various lengths, then the device is versatile and reusable, but the complexity of the magnetizer increases
Solution Approach 1:
The magnetizer incorporates movable or adjustable components such as sliding elements, telescopic sections, or reconfigurable magnetic assemblies that allow the device to dynamically adapt to different needle lengths. This dynamic adjustment capability provides versatility without requiring multiple fixed-configuration devices
Solution Approach 2:
The magnetizer is designed as a universal device that can accommodate various needle lengths and potentially other invasive medical devices through standardized interfaces and adjustable parameters. This multi-functionality allows a single device to serve multiple purposes across different procedural scenarios
