Pivotal Nasal Pack Device for Epistaxis Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nasal packing devices for treating epistaxis (nosebleeds) obstruct the nasal cavities completely, preventing patients from breathing through the nose during treatment.
Innovation Solution
A medical device featuring a pair of elongated structural components pivotally coupled, with each component having an operating portion that includes slits to hold nasal packs. These packs can be inflated to apply pressure to the bleeding site without blocking the nasal cavities entirely, allowing for breathing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nasal packs are inserted and inflated to apply pressure on the bleeding site, then epistaxis control is improved, but the nasal cavities are completely blocked preventing patient breathing
Solution Approach 1:
The nasal pack is divided into multiple segments or compartments, allowing selective inflation of only the portions needed to control bleeding while leaving other portions deflated to maintain air passages open for breathing
Solution Approach 2:
The nasal pack structure incorporates regions with different properties: some regions are designed to inflate and apply pressure to bleeding sites, while other regions remain deflated or have restricted expansion to preserve nasal airway patency
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
The device effectively controls or treats epistaxis by applying pressure to the bleeding site while maintaining an air passageway, enabling patients to breathe through the nose during treatment.
Implementation Method 1
Each nasal pack may then be injected or irrigated with saline to become enlarged (e.g., to inflate, especially circumferentially). The enlargement of each nasal pack inside of its respective nasal cavity enables the devices to apply pressure on the bleeding site

AI summary
A medical apparatus for controlling or treating epistaxis includes a first elongated structural component, a second elongated structural component, and a coupling component pivotally coupling the first and second elongated structural components to one another. The first elongated structural component includes a first handle portion, a first operating portion and a first through opening disposed between the first handle portion and the first operating portion. The second elongated structural component includes a second handle portion, a second operating portion and a second through opening disposed between the second handle portion and the second operating portion. The coupling component extends in the first and second through openings. Each one of the first and second operating portions may include an elongated body with one or more slits extending therealong. Each slits defines a receiving area for one or more nasal packs.
