Haemostatic Suction Cup with Internal Support for Bleeding Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for haemostatic control during surgical operations or vascular lesions face challenges such as difficulty in observing and suturing wounds, especially in delicate areas, and the inability to control bleeding effectively due to accessibility issues and tissue delicacy, leading to disruptions in the operation area.
Innovation Solution
A water-tight suction cup with a dome shape and internal support device, linked to an external vacuum system, creates a controlled depression to facilitate tissue migration and haemostasis, allowing for efficient and quick control of bleeding by surrounding the tissue area and applying a variable vacuum pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression or electrocoagulation operations are performed to achieve haemostasis, then bleeding is controlled, but the operation area is disrupted and tissue damage increases
Solution Approach 1:
The invention extracts the bleeding control function from direct surgical intervention (compression, electrocoagulation) and replaces it with a vacuum-based extraction system that removes blood from the wound area, thereby achieving haemostasis without direct tissue manipulation or thermal damage
Solution Approach 2:
The suction cup acts as an intermediary device between the bleeding wound and the vacuum source, creating a controlled environment that facilitates blood removal and tissue approximation without requiring direct surgical contact with the delicate tissue
2Loss of information
If the wound is left open for observation and suturing, then surgical precision is maintained, but bleeding continues and disrupts the operation area
Solution Approach 1:
The suction cup is applied to the wound area before definitive suturing, preliminarily controlling the bleeding and creating a stable field that allows subsequent surgical steps to proceed without disruption from active hemorrhage
3Reliability
If clamping is used to control the wound, then bleeding is stopped, but it is not possible to control wounds in inaccessible or dangerous areas
Solution Approach 1:
The suction cup device provides a universal haemostatic solution that can be applied to various wound types and locations (superficial wounds, delicate internal organs, inaccessible areas) without requiring adaptation of the basic mechanism, unlike clamping which is location-specific
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 solution enables effective and sustained haemostasis, minimizing bleeding and facilitating surgical procedures by creating a controlled environment for tissue healing, even in hard-to-reach or delicate areas, thus ensuring optimal surgical conditions.
Implementation Method 1
linked to an external suction and vacuum device, thus creating in said volume, between the suction cup and the tissue area, a depression having a determined value

AI summary
Device for haemostatic control of a blood flow, comprising a suction cup which provides leaktight coverage and is able to surround and be applied tightly to a tissue area (2) that is to be treated, said tissue area (2) being the site of a haemorrhage or of a blood flow that is to be controlled, this suction cup (3) coming into contact with the periphery of the tissue area and delimiting an internal volume (8) which is connected in a leaktight manner, by a catheter or a similar connecting tube (7), to an external aspiration element that establishes a vacuum, so as to create an underpressure of defined value within this volume between the suction cup and the tissue area, the suction cup (3) having the general shape of a dome (4), of which the base (5) supports an inner bearing element (11) that can be arranged opposite the tissue area (2) under the suction cup (3). The invention lies in the inner bearing element being formed by a solid obturator (11) or an open grill (13).
