Nasal Hemostasis Insert with Through Channel for Blood Expulsion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nosebleed treatment devices lack effective mechanisms for applying blood clotting compositions directly to the nasal interior, efficiently expelling excess blood, and providing a container for storage and easy access, particularly for patients on blood thinners.
Innovation Solution
A nasal insert with a tapered sponge-like surface coated with chitosan or ACH drug for direct application, a handle for insertion and removal, and a through channel for blood expulsion and breathing, stored in a container designed for easy access and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tampon-like device is inserted into the nostril to stop bleeding, then the nosebleed stopping function is improved, but there is no mechanism to expel excess blood from the nose while the tampon remains in place
Solution Approach 1:
The device is divided into distinct functional segments: a tapered insertion portion with blood-clotting composition for stopping bleeding, and a separate channel system for blood expulsion. This segmentation allows the device to simultaneously perform hemostasis and drainage functions without interference between the two mechanisms.
Solution Approach 2:
The device introduces an intermediary channel structure that mediates between the bleeding site and the external environment. This channel allows excess blood to be expelled while the tampon remains in place to continue its hemostatic function, resolving the conflict between stopping bleeding and removing excess blood.
2Reliability
If a nasal insert is placed into the nostril to stop bleeding, then the bleeding control function is improved, but there is no efficient way to store the nasal insert within a special container prior to insertion
Solution Approach 1:
The device is pre-packaged in a container designed specifically for its storage and rapid deployment. The container is configured to hold the nasal insert in a ready-to-use state and allows for quick access during a nosebleed emergency, eliminating the need for preparation or assembly at the moment of need.
Solution Approach 2:
The container serves multiple functions: it protects the nasal insert during storage, maintains the blood-clotting composition in its effective state, and provides a mechanism for rapid deployment. This multi-functionality integrates storage and access efficiency into the overall device system.
3Reliability
If a device without a through channel is used to stop nosebleed, then the blood clotting function is improved, but the patient cannot breathe through the device while it remains in the nostril
Solution Approach 1:
The device structure is segmented into a solid tampon portion for blood clotting and a separate through-channel portion for air passage. This segmentation allows the blood-clotting composition to maintain its effectiveness while providing an unobstructed path for breathing through the device.
Solution Approach 2:
Different regions of the device have different properties: the tampon portion is designed with blood-clotting composition for hemostasis, while the channel region is designed with open space for air flow. This local differentiation of properties allows both functions to coexist without interference.
4Reliability
If a device without a handle is used for nosebleed treatment, then the blood clotting function is improved, but there is no convenient mechanism for insertion and removal of the device
Solution Approach 1:
The device is segmented into a functional portion (tapered insert with blood-clotting composition) and a manipulative portion (handle). This segmentation allows the blood-clotting function to be optimized in the insert portion while the handle provides ergonomic advantages for insertion and removal.
Solution Approach 2:
The handle serves as an intermediary between the user's hand and the delicate tapered insert. It provides a grip surface that allows precise control during insertion and easy leverage for removal, protecting the blood-clotting composition from damage while maintaining operational convenience.
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 stops nosebleeds in a short time by promoting blood clotting and healing, allowing for efficient blood expulsion and breathing, and is designed for quick and easy use, even for patients on blood thinners.
Implementation Method 1
The outside tapered surface of the top section of the bleed stopping device is coated with a sponge-like material which is impregnated with a blood clotting composition, such as, for example, chitosan or ACH drug that is brought in contiguous contact with the inner surface of the bleeding nostril in order to clot blood

AI summary
A blood coagulant assembly includes a blood coagulant device adapted to be insertable into a nostril of a patient to stop a nose bleed. The blood coagulant device is mounted within a blood coagulant device container which has a top container section and a lower container section secured to each other in a releasable manner. The blood coagulant device is mounted in a fixed position within the blood coagulant device container prior to its removal from the blood coagulant container. The blood coagulant device has a rigid handle configured with a handle lower section and a handle upper section contoured with a channel passing through both the lower and upper handle sections. A blood coagulant mechanism is secured to an outer surface of the handle upper section and a to a ledge section of the handle member which extends radially at a joint location of the handle's lower and upper sections.
