Needle Locating Device for Pneumothorax Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency situations, such as combat or emergency room settings, medical personnel face challenges in accurately locating the correct position for needle insertion during chest decompression procedures for pneumothorax conditions due to increased pressures and stress, leading to potential misdiagnosis and additional patient injury.
Innovation Solution
A needle locating device that uses physiological reference points and adjustable markings to guide the insertion of a pneumothorax relief needle, ensuring precise placement by aligning reference indicators with anatomical structures like the clavicle and nipple, and sliding an elongated body to display matching incremental markings for accurate needle insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If medical personnel perform needle insertion under high pressure and stress, then emergency treatment can be provided quickly, but the accuracy of needle placement deteriorates
Solution Approach 1:
The locating device performs preliminary identification and marking of the correct needle insertion zone on the patient's chest before the actual needle insertion is performed. By pre-determining and visualizing the target location through reference indicators and anatomical landmark alignment, the device enables rapid and accurate needle placement even under high-stress emergency conditions.
Solution Approach 2:
The locating device acts as an intermediary tool between the medical personnel and the patient's anatomy. It provides visual reference indicators that mediate the relationship between the operator and the anatomical structures, guiding accurate needle placement without requiring the personnel to directly identify the correct zone under pressure.
2Productivity
If medical personnel are under increased pressure in emergency situations, then rapid response is achieved, but the reliability of correct needle insertion deteriorates
Solution Approach 1:
The locating device provides visual feedback to the medical personnel through reference indicators that show the correct needle insertion zone. This feedback mechanism confirms the accurate positioning of the needle tip within the target area, ensuring reliable insertion while maintaining rapid response capability.
Solution Approach 2:
By pre-identifying and marking the correct insertion zone before the procedure, the device establishes reliability in advance, ensuring that when the needle is inserted rapidly under pressure, it will reliably reach the correct location.
3Measurement precision
If a locating device is introduced to improve needle placement accuracy, then measurement precision improves, but device complexity increases
Solution Approach 1:
The locating device is segmented into distinct functional components: reference indicators for anatomical alignment, a locating element for positioning, and visual reference markers for the correct insertion zone. This segmentation allows each component to perform its specific function simply, avoiding overall device complexity while maintaining high measurement precision.
Solution Approach 2:
The device uses visual copies or representations of anatomical landmarks and target zones through reference indicators and markings. These visual copies provide accurate guidance without requiring complex mechanical or electronic systems, achieving precision through simplified visual representation rather than complexity.

AI summary
A template for locating a proper place for inserting a needle. The template has two reference indicators that are placed on a person's body and an elongated body, with incremental markings on each side of the elongated body, that moves relative to the two reference indicators. The incremental markings on each side of the elongated body can be scaled differently. One reference indicator is placed over the clavicle and the other is placed over the nipple on the same lateral side. The elongated body is moved until the reference indicators are each lined up with equivalent incremental markings on each half of the elongated body. When the reference indicators are lined up with matching incremental markings, a fixed target, positioned between the two sets of incremental markings, will indicate a proper location for inserting a pneumothorax relief needle.
