Radiation Probe Holder for Nuclear Medication Administration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The delivery of nuclear medications is often imprecise, and staff members are exposed to undesirable radiation doses due to the difficulty in consistently holding a radiation measuring device, such as a Geiger counter probe, during administration.
Innovation Solution
A device with a substrate that securely retains a radiation probe and fluid line, maintaining a constant geometry to accurately measure radioactivity and reduce staff exposure, using low Z materials like acrylic or plastic, and optionally filled with liquids for enhanced shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a radiation probe is manually held during administration of nuclear medication, then the radiation levels can be monitored, but the measurement precision deteriorates due to inconsistent positioning and staff exposure to radiation increases
Solution Approach 1:
The patent introduces an intermediary device (the holder with aperture and fluid line positioning features) that mediates between the radiation probe and the medication delivery system. This holder provides a fixed geometric relationship between the probe and fluid line, eliminating manual positioning errors while maintaining radiation monitoring capability. The intermediary structure ensures consistent measurement geometry without requiring staff to hold the probe close to the medication line.
2Measurement precision
If the radiation probe is positioned close to the fluid line for accurate measurement, then measurement precision improves, but staff radiation exposure increases
Solution Approach 1:
The patent resolves the spatial conflict by transitioning from a one-dimensional handheld approach to a multi-dimensional fixed structure. The holder provides three-dimensional positioning with the aperture aligned perpendicular to the fluid line, creating an optimized measurement geometry that maintains measurement precision while allowing the probe to be positioned at a safer distance from the medication source.
3Device complexity
If manual holding of the radiation probe is used, then device complexity is low, but measurement precision and staff protection deteriorate
Solution Approach 1:
The patent segments the measurement system into distinct functional components: the holder structure, the aperture for probe positioning, the fluid line routing features, and the measurement probe itself. This segmentation allows each component to be optimized for its specific function while maintaining overall system simplicity. The holder provides structural support and positioning without requiring complex mechanisms.
