Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ostomy devices face issues with insecure adhesion of the base plate to the skin due to insufficient adhesiveness, leading to frequent system failures and increased costs from replacing incorrectly attached base plates.
Innovation Solution
A device featuring a heat storage plate that warms the adhesive base plate to body temperature, ensuring uniform pressure distribution and optimal adhesive performance, using a thermometer for temperature control and a metallic heat storage plate with a receiving opening for drainage, made from lead-free, rustproof materials like aluminum alloys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a self-adhesive base plate is used to attach to the skin, then the attachment should be secure and long-lasting, but the adhesive properties are insufficient at room temperature leading to frequent system failures
Solution Approach 1:
The adhesive base plate is pre-heated to body temperature (37°C) before application to the skin. This preliminary heating action activates the adhesive properties of the pressure-sensitive adhesive, ensuring optimal bonding strength from the moment of application and preventing premature detachment.
Solution Approach 2:
The temperature parameter of the adhesive base plate is changed from room temperature to body temperature (37°C) through pre-heating. This parameter change activates the pressure-sensitive adhesive, transforming it from a non-adhesive state to a highly adhesive state, thereby resolving the insufficient adhesive properties at room temperature.
2Reliability
If additional belts are attached to provide support, then attachment security improves, but device complexity increases
Solution Approach 1:
The additional support belts are extracted from the system and replaced by a single heat storage plate that provides both heating and pressing functions. This eliminates the need for multiple separate components (belts, clips, etc.) while maintaining or improving attachment security through thermal activation of the adhesive.
3Ease of operation
If the base plate is pressed down by hand, then application is simple, but uniform pressure distribution cannot be achieved leading to incomplete contact and detachment
Solution Approach 1:
A heat storage plate is introduced as an intermediary tool between the user and the adhesive base plate. This plate distributes pressure uniformly across the entire surface of the base plate while simultaneously heating it to body temperature, achieving both simple operation and uniform pressure distribution that manual pressing cannot provide.
4Reliability
If the adhesive area is made larger to improve bonding, then attachment security improves, but the device becomes more noticeable and uncomfortable for the patient
Solution Approach 1:
Instead of increasing the adhesive area, the temperature parameter of the existing adhesive area is optimized by pre-heating to body temperature. This parameter change maximizes the bonding efficiency of the available adhesive surface, achieving secure attachment without expanding the device size or making it more noticeable to the patient.

AI summary
The invention relates to a device for attaching a base plate to the skin of individuals with stoma appliances, which consist of a collection bag and a self-adhesive base plate, as well as a method for its application and use. The object of the invention is to provide a device for the secure and gentle attachment of a stoma appliance base plate. The device should be simple in design, inexpensive to manufacture, and easy for every user to apply. In particular, it should enable uniform pressure distribution within an optimal temperature range. According to the invention, the device consists of a sufficiently large heat storage plate (1) with a receiving opening (5) for a thermometer (2). This receiving opening (5) provides means for fixing the thermometer (2), which is preferably waterproof and corrosion-resistant.The heat storage plate (1) is selected such that, when the device is used, the temperature drop on the surface of the heat storage plate (1) does not exceed 5°C within 2 minutes. For base plates (10) with a snap-fit coupling, a profile recess (4) may be provided on the contact side, corresponding to the outer contour of a projection (14) present on the base plate (10), the depth of which is at least equal to the height of this projection (14). The thermometer (2) may be attached with a retaining ring (3) or with a thermally conductive adhesive. An integrated drainage hole (7) is advantageous.
