Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional medical stabilization devices for monitoring pressure in patients are inconvenient and impractical, especially in situations where patients are awake, moving, or in confined spaces, as they require constant level adjustments and are not easily adaptable for secure and protective attachment of transducers to the phlebostatic axis.

Innovation Solution

A stabilization device comprising a flexible pad with an instrument holder and protection cover, which includes a swivel joint and clamp system, allowing secure attachment of instruments along the phlebostatic axis, providing flexibility and protection from manipulation, and enabling easy adjustment and protection of transducers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional stabilization devices are used to secure transducers, then the transducers can be attached to the patient, but constant level adjustments are required and the devices are not adaptable for secure and protective attachment

Engineering Contradiction:

Improvelevel maintenanceVSAvoidadjustment frequency

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device incorporates a swivel joint that allows the holder to rotate and adapt to patient movement while maintaining the transducer at the correct phlebostatic axis level. This dynamic adjustment mechanism eliminates the need for constant manual level adjustments by automatically accommodating position changes through rotational freedom.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The stabilization device is divided into separate functional components: a flexible pad for attachment, a holder for securing the transducer, and a swivel joint connecting them. This segmentation allows each component to perform its specific function independently, with the swivel joint specifically addressing the level maintenance issue by decoupling the attachment surface from the transducer holder orientation.

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If conventional stabilization devices are used, then transducers can be attached, but they are not protected from manipulation and are inconvenient in confined spaces

Engineering Contradiction:

Improveprotection from manipulationVSAvoiddevice structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protection cover is designed to envelop and enclose the holder and transducer assembly, creating a protective shell. This nested structure places the vulnerable components (holder and transducer) inside the protective cover, shielding them from external manipulation while maintaining a relatively simple overall device structure.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The protection cover is connected to the holder via a hinge, allowing it to pivot between open and closed positions. This dynamic design enables the cover to adapt to different operational states - open for installation/access and closed for protection - without requiring a complex locking mechanism or multiple separate components.

Inventive Principle:

Principle #15Dynamics

3Object-affected harmful factors

If the protection cover is designed to enclose the clamp and instrument, then protection from manipulation is improved, but the device complexity increases

Engineering Contradiction:

Improveprotection from manipulationVSAvoiddevice structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The protection cover serves multiple functions: it protects the transducer and holder from manipulation, provides a barrier against contamination, and can be easily opened for access. By designing a single component that performs multiple protective and operational roles, the overall device complexity is minimized while achieving comprehensive protection.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A stabilization device is provided for attaching an instrument along a phlebostatic axis of a patient's torso, said instrument having a tether to a monitor. The stabilization device includes a flexible pad, an instrument holder, and a protection cover. The flexible pad contacts the torso along the phlebostatic axis. The instrument holder is disposed on the pad. The holder includes a clamp to secure the instrument. The protection cover connects to the holder by a hinge and rotates along the hinge between an open position and a close position. In the close position, the cover contains the clamp and the instrument. A swivel joint connects the holder to the pad for angular independence.
