Solution Overview

Problem

Current ultrasound patches struggle with maintaining stable imaging during procedures due to misalignments, subject movement, and varying vessel depths, requiring cumbersome methods like gel-filled gloves for focus adjustment.

Innovation Solution

An apparatus with two fixing units and an adjustable holding unit for ultrasound patches, allowing manual or mechanical adjustments to compensate for placement errors and subject movement, and incorporating a stand-off portion for focus depth adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If ultrasound patches are fixed to the subject surface, then hands-free imaging is enabled, but misalignments and subject movement reduce imaging accuracy

Engineering Contradiction:
Improvehands-free imagingVSAvoidimaging accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The holding unit incorporates an adjustable mechanism that allows dynamic repositioning of the ultrasound patch relative to the fixing units. This enables the system to maintain imaging accuracy despite misalignments or subject movement by allowing the patch position to be adjusted within the fixed framework.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system is divided into separate functional components: fixing units that provide stable attachment to the subject, and a holding unit that accommodates the ultrasound patch with adjustable positioning. This segmentation allows independent optimization of stability and adjustability.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a single standard probe is used, then device simplicity is maintained, but focus depth cannot be adjusted for vessels at different depths

Engineering Contradiction:
Improveprobe simplicityVSAvoidfocus depth adjustment
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The holding unit includes an adjustable mechanism that allows dynamic change in focus depth by repositioning the ultrasound patch relative to the subject surface. This enables a single standard probe to adapt to different imaging depths without requiring multiple specialized probes.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If gel-filled gloves are used for focus adjustment, then focus depth can be changed, but the method becomes cumbersome and complex

Engineering Contradiction:
Improvefocus depth adjustmentVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention extracts the focus adjustment function from the complex gel-filled glove system and integrates it directly into the holding unit mechanism. This provides a simpler, more direct method for focus depth adjustment without the cumbersome nature of gel-filled gloves.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The invention provides for a method and an apparatus (300) for positioning an ultrasound patch on a surface of a subject. The apparatus includes a first fixing unit (210) and a second fixing unit (310) adapted to be fixed to a surface of the subject at a first location and second location, respectively, with a space of exposed surface of the subject between them. The apparatus further comprises a holding unit (260) for positioning on the exposed surface of the subject within the space between the fixing units, the holding unit being adapted to receive the ultrasound patch.The holding unit is adapted to be coupled with the first and second fixing units at the surface of the subject and, when the holding unit is coupled to the first fixing unit and the second fixing unit, the position of the holding unit is adjustable relative to the first fixing unit and the second fixing unit.
