Cuff Valve Structure With Relocated Exhaust for Wider Joining Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas control devices face challenges in reducing profile while maintaining a wide joining area for large containers, due to the presence of an exhaust hole on the second plate which limits the area available for cuff attachment.
Innovation Solution
Incorporating a channel forming plate with an exhaust hole, allowing the second plate to have a wider joining area by relocating the exhaust hole to the channel forming plate, thus enabling a larger area for cuff attachment without compromising the device's profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the exhaust hole is provided on the second plate, then the device structure is simple, but the joining area for the container is reduced
Solution Approach 1:
The device is divided into separate functional plates: a first plate with a first vent hole, a second plate with a second vent hole, and a channel forming plate with an exhaust hole. This segmentation allows each plate to have optimized functions, with the second plate dedicated to providing a wide joining area for the container while the channel forming plate handles the exhaust function separately.
Solution Approach 2:
The channel forming plate acts as an intermediary component between the first plate and the second plate. It provides the exhaust hole and forms channels that connect the vent holes to the exhaust, allowing the second plate to focus on providing a large joining area without needing to integrate the exhaust hole directly into its structure.
2Volume of moving object
If the nozzle is removed for profile reduction, then the device becomes more compact, but the joining area for the container is limited
Solution Approach 1:
Instead of extending the device outward with a traditional nozzle structure, the exhaust function is integrated into the channel forming plate that connects between the first and second plates. This dimensional reorganization allows the device to maintain a compact profile while the second plate provides an extended joining area on its outer surface for connecting large containers.
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
This configuration allows for a reduction in profile while providing a wide joining area, enhancing the device's ability to connect larger containers, and effectively managing air flow and pressure during operations like blood pressure measurement.
Implementation Method 1
the valve member forming a first valve chamber with the first plate and the channel forming plate and forming a second valve chamber with the second plate and the channel forming plate, the valve member connecting the first channel and interrupting the second channel or interrupting the first channel and connecting the second channel on the basis of a pressure of the first valve chamber and a pressure of the second valve chamber

AI summary
A gas control device includes a pump, a valve, a cuff, and a controller. The valve includes a first plate having a first vent hole and a first vent hole, a channel forming plate having an exhaust hole and an exhaust channel, a second plate having a second vent hole, and an edge separation plate. A manchette rubber tube in the cuff is joined to the periphery of the second vent hole in the second plate by an adhesive, and thus the valve is connected to the cuff. The exhaust hole is opened to the atmosphere. The pump includes a pump housing having a discharge hole and a discharge hole. The upper surface of the pump housing is joined to the bottom surface of the edge separation plate.
