Hemostatic Spray Pneumatic Delivery for Wide Bleeding Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical procedures for stopping bleeding, such as clip-based and high-frequency treatments, are ineffective in completely halting blood flow from wide bleeding areas, often leading to recurring bleeding and tissue damage.
Innovation Solution
A hemostatic sprayer is designed with a powder casing containing biocompatible hemostatic powders coupled to an aerosol-type receptacle, where compressed gas is released to spray the hemostatic powders onto the bleeding site, enhancing blood flow cessation and allowing for easier application and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If clip-based medical procedure is used to stop blood flow, then the procedure is simple to perform, but the bleeding cannot be completely stopped when the bleeding portion is wide
Solution Approach 1:
The patent employs pneumatic principles by using compressed gas to spray hemostatic powder onto the bleeding site. The gas propels the powder through a nozzle, creating a high-velocity stream that can cover wide bleeding areas effectively, resolving the contradiction between procedural simplicity and hemostatic effectiveness for large bleeding surfaces.
Solution Approach 2:
The patent changes the physical state and delivery method of the hemostatic agent from solid clips or localized cautery to aerosolized powder delivered via gas flow. This parameter change allows the hemostatic material to be distributed over wide areas while maintaining procedural simplicity through a single spray action.
2Reliability
If high-frequency medical treatment is used to stop blood flow, then the blood flow can be stopped effectively, but it takes much time to heat the bleeding portion and causes widespread burns
Solution Approach 1:
The patent replaces thermal energy delivery with pneumatic energy delivery. Compressed gas propels hemostatic powder instantaneously onto the bleeding site, eliminating the time-consuming heating process of high-frequency treatment while avoiding thermal damage to surrounding tissues.
Solution Approach 2:
The patent substitutes the thermal field (high-frequency heating) with a mechanical field (compressed gas flow). This replacement achieves rapid hemostasis without the time delay and tissue damage associated with thermal methods.
3Reliability
If high-frequency medical treatment is used to stop blood flow, then the blood flow can be stopped, but the human tissue is uselessly destroyed and bleeding may reoccur
Solution Approach 1:
The patent uses compressed gas to deliver hemostatic powder physically onto the bleeding site without thermal energy. This pneumatic delivery method achieves hemostasis through the mechanical action and chemical properties of the powder, completely avoiding the tissue destruction caused by high-frequency heating.
Solution Approach 2:
The patent converts the potential harm of thermal energy (which destroys tissue) into beneficial mechanical energy (compressed gas flow) that delivers the hemostatic agent precisely without damage. The harmful thermal effect is replaced by a beneficial pneumatic effect.
4Ease of operation
If clip-based or high-frequency procedure is used, then the procedure can be performed, but there is a high likelihood that bleeding will reoccur due to active bleeding and severe bleeding
Solution Approach 1:
The patent changes the delivery method to aerosolized powder spray, which allows for more complete and uniform coverage of the bleeding site compared to clips or focused cautery. This parameter change in delivery methodology ensures better hemostatic effect and reduces bleeding recurrence while maintaining procedural simplicity.
Solution Approach 2:
The patent transitions from zero-dimensional point contact (clips) or localized treatment (cautery) to three-dimensional aerosol cloud delivery. This dimensional change allows the hemostatic agent to envelop and cover the entire bleeding surface simultaneously, improving effectiveness and preventing recurrence.

AI summary
Proposed is a hemostatic sprayer for stopping a flow of blood from a bleeding portion of the human body, the hemostatic sprayer including a powder casing inside which an accommodation space is formed and which includes inlet and outlet ports, hemostatic in the form of powders being pre-stored in the accommodation space, and the inlet and outlet ports connecting thereto, and a receptacle inside which gas is compressed and pre-stored and which has a supply port on one side, the supply port separably connecting to the inlet port, wherein the supply port is open as a result of pressing by the powder casing, wherein, through the open supply port, the gas is supplied with a preset pressure toward the inlet port and flows into the accommodation space through the inlet port, and wherein the gas flowing is discharged together with the hemostatic through the outlet port while scattering the hemostatic.
