Hemostatic Device Self-Inflation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hemostatic devices require a separate dedicated instrument for inflating the inflatable portion, which is cumbersome and prone to errors, and may lead to incomplete inflation or loss of the dedicated instrument.
Innovation Solution
A hemostatic device with an elastically transformable injection part and a tube body that connects the inflatable portion and injection part, featuring a cover portion with a communication portion that allows gas flow during inflation and blocks it during deflation, enabling simple operation without a separate instrument.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate dedicated instrument is used to inflate the inflatable portion, then the inflation can be performed, but it requires additional effort to carry and connect the instrument, and there is a risk of loss or incomplete inflation
Solution Approach 1:
The injection part is integrated into the hemostatic device itself, merging the inflation function with the main device. The tube body connects the injection part directly to the inflatable portion, eliminating the need for separate dedicated instruments and reducing the number of components while ensuring reliable inflation.
Solution Approach 2:
The hemostatic device becomes self-sufficient by incorporating its own injection part and tube body system. The device can inflate itself without requiring external instruments, making it self-service capable and eliminating the risks associated with separate instruments.
2Ease of operation
If a separate dedicated instrument is used to inflate the inflatable portion, then the inflation function is achieved, but it increases the effort required to carry and connect the instrument
Solution Approach 1:
By merging the injection part with the hemostatic device and using a flexible tube body for connection, the inflation operation becomes part of the standard device operation. This eliminates the need to carry and connect separate instruments, significantly reducing preparation time and improving ease of operation.
3Reliability
If a separate dedicated instrument is used, then inflation can be performed, but there is a possibility that the instrument may be lost or not available when needed
Solution Approach 1:
The injection part is permanently integrated into the hemostatic device structure, ensuring that the inflation capability is always available with the device. This merging eliminates the risk of losing or not having the inflation instrument available, as it is an inherent part of the device itself.
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 allows for easy and controlled inflation and deflation of the inflatable portion, eliminating the need for a separate instrument and reducing the risk of errors, while maintaining airtightness and efficient hemostasis.
Implementation Method 1
an injection part which is elastically transformable and is capable of injecting gas into the inflatable portion
Implementation Method 2
the cover portion has a communication portion that allows communication between the lumen of the inflatable portion and the lumen of the injection part by gas discharged from the hole portion
Implementation Method 3
by the lumen of the tube body becoming negative pressure with respect to the inflatable space of the inflatable portion when the injection part is elastically transformed to return to an original shape, the communication portion blocks communication
