Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current devices for treating epistaxis, such as nasal tampons and balloon-containing devices, are often painful, ineffective, and require extensive training for proper use, while also risking nasal occlusion and re-bleeding upon removal.

Innovation Solution

A device with curvilinear sidewalls and protrusions/apertures that is inserted between the upper lip and gingiva to occlude blood flow to the hemorrhage, providing non-invasive and painless treatment without the need for nasal packing or extensive training.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If nasal tampons are used to treat epistaxis, then bleeding is stopped effectively, but the device causes pain during insertion and removal, may induce trauma to the nostril, and occludes the nasal airway

Engineering Contradiction:

Improveeffectiveness in stopping bleedingVSAvoidpain, trauma, and nasal occlusion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a bite block as an intermediary device that applies pressure to the superior labial artery through the lip and gingiva, rather than directly inserting material into the nostril. This mediator approach stops anterior epistaxis by compressing the blood supply at the frenulum area, avoiding direct nasal trauma while maintaining effectiveness

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical nasal packing system with a bite block mechanism that uses the user's own bite force to apply continuous pressure. This substitution eliminates the need for provider insertion and removal, reducing pain and trauma while maintaining hemostatic effectiveness

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If balloon-containing devices are used to treat epistaxis, then bleeding is stopped, but the device may exacerbate skull fractures and displace them into the cranial vault

Engineering Contradiction:

Improveeffectiveness in stopping bleedingVSAvoidrisk of displacing skull fractures

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The bite block serves as a safe intermediary that applies pressure externally through the lip and gingiva to the superior labial artery, avoiding direct insertion into the nasal cavity. This eliminates the risk of balloon devices contacting and potentially displacing skull fractures while maintaining effectiveness in stopping anterior epistaxis

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If pressure inserts with bite tabs or stems are used to treat epistaxis, then the insert can be held in place, but the device becomes bulky and visually unappealing, and requires user action to maintain position

Engineering Contradiction:

Improveability to maintain positionVSAvoidbulky size and visual appearance

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The bite block is designed to be self-retaining through the user's natural bite, eliminating the need for bite tabs, stems, or other retention mechanisms. The device is held in place automatically by the user's occlusion force, making it compact, aesthetically pleasing, and requiring no user adjustment while maintaining position stability

Inventive Principle:

Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

AI summary

The present disclosure relates to devices and methods for treating epistaxis. In some embodiments, a device for occluding epistaxis includes a first curvilinear wall, a second curvilinear wall, and a third curvilinear wall each disposed at a top portion of the device. The device has an x-axis, y-axis, and z-axis, and the top portion is relative to the y-axis. The device includes a fourth wall and a fifth wall each disposed at a bottom portion relative to the y-axis of the device. The fourth wall and the fifth wall independently are substantially straight or curvilinear. The device includes a first end including a front first end portion and a back first end portion. The first end is curvilinear corresponding to the first curvilinear wall, and the first end is disposed at an angle relative to the x-axis.
