Caesarean Delivery Blood Flow Reduction Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During Caesarean delivery operations, sudden and uncontrollable hemorrhages can occur due to anatomical or physiological variations in blood vessels, posing risks to both the mother and baby, as existing devices fail to effectively manage the bleeding, obscuring the surgical site and complicating the procedure.
Innovation Solution
A blood-flow reduction device with a frame that constricts blood flow by applying pressure around the incision area, allowing the surgeon to access the uterus safely and rapidly, and optionally includes an aspirator to remove excess blood, ensuring clear visibility and reducing hemorrhage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a cut is made through the abdomen layers during Caesarean delivery, then the baby can be accessed and delivered, but sudden uncontrollable hemorrhage occurs obscuring the surgical site
Solution Approach 1:
The frame is applied to the patient's abdomen before the incision is made, positioning the compression elements over the uterine incision site in advance. This preliminary placement ensures that when the cut is made, the frame is already in position to immediately compress and control hemorrhage, allowing rapid baby delivery without waiting to apply hemostatic measures after bleeding starts
Solution Approach 2:
The frame acts as an intermediary device between the surgeon's cutting action and the hemorrhage control need. It provides a mechanical interface that translates surgeon-applied pressure into localized compression on the uterine vessels, mediating the control of blood flow while maintaining surgical access through the frame's opening
2Object-affected harmful factors
If pressure is applied to block blood flow, then hemorrhage is controlled, but the surgical site becomes obscured by the frame structure
Solution Approach 1:
The frame is designed with a segmented structure featuring a central opening that divides the compression function from the visualization need. The compression elements are positioned around the periphery of the opening, allowing blood flow control at the uterine incision site while maintaining a clear central area for surgical visualization and baby access
Solution Approach 2:
The frame applies compression locally at specific points around the uterine incision site rather than uniformly across the entire surgical field. The compression elements are strategically positioned to target blood vessels while leaving the central surgical area open and visible, providing localized hemorrhage control without obscuring the overall surgical site
3Reliability
If existing devices are used for hemorrhage control, then some blood flow reduction is achieved, but they fail to prevent sudden uncontrollable hemorrhage rapidly enough
Solution Approach 1:
The frame is prepared and positioned on the patient's abdomen before the uterine incision is made, with compression elements already aligned over the incision site. This preliminary positioning eliminates the time delay associated with applying hemostatic devices after bleeding begins, ensuring immediate hemorrhage control capability from the moment the cut is made
Solution Approach 2:
The frame incorporates dynamic compression capability where the degree of pressure can be adjusted in real-time by the surgeon based on the actual bleeding rate. The compression elements can be dynamically tightened or loosened to match the hemorrhage severity, providing adaptive control that responds to changing surgical conditions
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 prevents uncontrollable bleeding and maintains a clear surgical site, enabling rapid and safe completion of the operation, thereby reducing risks to both the mother and baby.
Implementation Method 1
at least one gripping means on the frame for exerting a pressure with the frame on the patient giving birth, before making the cut, and thus reducing the blood flow towards the area inside the frame
