Solution Overview

Problem

Current methods for treating epistaxis, such as nose plugs, nasal tampons, and nasal clips, often exacerbate bleeding due to irritation and inadequate pressure, while nasal gels can overflow and nasal clips can slip off, necessitating an improved device and method to restrict blood flow effectively.

Innovation Solution

A device comprising an insertion body and an external body with magnetic or spring mechanisms that compress blood vessels in the face to restrict blood flow, using adjustable magnetic forces or spring tension to pinch tissue and control bleeding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If nasal plugs, nasal tampons, or tissue are used to treat epistaxis, then bleeding can be addressed, but the bleeding worsens due to irritation from friction and insufficient pressure

Engineering Contradiction:

Improvepressure applied to blood vesselsVSAvoidirritation to vessels

Core Design Contradiction:

ForceVSObject-affected harmful factors

Solution Approach 1:

The patent replaces traditional mechanical nasal plugs and tampons with a magnetic field-based system. Magnets positioned in the nasal cavity generate magnetic fields that apply force to blood vessels without physical contact, eliminating friction-induced irritation while maintaining sufficient pressure to stop bleeding.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces magnetic fields as an intermediary between the treatment device and the blood vessels. Instead of direct mechanical contact, the magnetic field serves as a mediator to apply force to the vessels, achieving hemostasis without the harmful friction caused by traditional nasal plugs.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If nasal gels are used to treat epistaxis, then calcium ions act as absorbers to blood, but the gel can be easily overflown with strong nosebleeds and irritates the individual's nostrils

Engineering Contradiction:

Improveabsorption capacityVSAvoidirritation to nostrils

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical absorption mechanisms (nasal gels) with magnetic field-based mechanical force application. The magnetic system directly applies force to blood vessels to stop bleeding, providing superior control for strong nosebleeds without the irritation caused by gel substances in the nostrils.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If nasal clips are used to treat epistaxis, then the nostrils are kept closed, but they do not address the vasculature causing the bleeding and can easily slip off

Engineering Contradiction:

Improveease of applicationVSAvoideffectiveness in stopping bleeding

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces external mechanical compression (nasal clips) with an internal magnetic field-based system. Magnets positioned within the nasal cavity create magnetic fields that directly target and apply force to the bleeding vessels, ensuring reliable hemostasis while maintaining ease of application and removal.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If nasal clips are used to treat epistaxis, then the nostrils are kept closed, but they can easily slip off since they are not designed to accommodate various nose sizes and shapes

Engineering Contradiction:

Improveaccommodation of various nose sizes and shapesVSAvoidstability of device

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent employs magnets of varying sizes, shapes, and magnetic strengths that can be selected and positioned to match different nasal cavity anatomies. This parametric flexibility allows the system to adapt to various nose sizes and shapes while maintaining stable positioning and reliable bleeding control.

Inventive Principle:

Principle #35Parameter changes
