Medical Device Mounting Base With Adjustable Straps for Sterile Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices attached to patients using adhesives lack flexibility in positioning and re-positioning, compromise sterility, and cause discomfort due to skin irritation.
Innovation Solution
A medical device attachment apparatus featuring adjustable straps, cushions, and mounting bases with connectors, allowing secure attachment to the patient's body, accommodating various body types, and ensuring stability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesives are used to attach the medical device to the patient's skin, then the device is securely fixed, but the patient experiences skin irritation and discomfort
Solution Approach 1:
The patent introduces a mounting base as an intermediary component between the medical device and the patient's body. The mounting base is attached to the patient's skin using adhesives, while the medical device is then secured to the mounting base using mechanical fastening elements (latches, clips, or snap-fit mechanisms). This intermediary structure allows the adhesive to contact the mounting base rather than directly contacting the patient's skin, eliminating skin irritation while maintaining secure attachment through the mechanical fastening system.
2Reliability
If adhesives are used to attach the medical device, then the device is firmly secured, but the device cannot be easily re-positioned or adjusted
Solution Approach 1:
The mounting base incorporates adjustable positioning mechanisms that allow dynamic repositioning. The mechanical fastening elements (latches, clips, or snap-fit mechanisms) can be easily engaged and disengaged, enabling the medical device to be removed, repositioned, and reattached to different locations on the mounting base or even different areas of the patient's body. This dynamic adjustment capability is maintained while the mounting base itself remains securely attached to the skin via adhesives.
3Reliability
If adhesives are used to attach the medical device, then the device is securely fixed, but sterility cannot be maintained if the device is reusable and non-sterile
Solution Approach 1:
The system is segmented into three distinct components: (1) the mounting base that contacts the patient's skin and requires sterility, (2) the medical device that may be reusable and non-sterile, and (3) the mechanical fastening elements that connect them. This segmentation allows the mounting base to be sterilized and disposed of after a single use, while the more expensive medical device can be reused without sterilization. The sterile barrier is maintained at the skin-contact interface, while the non-sterile device is isolated in the connection interface.
4Ease of operation
If the medical device is attached directly to the patient's body, then positioning flexibility is reduced, but attachment simplicity is improved
Solution Approach 1:
The mounting base serves as a mobile platform that can be positioned at different locations on the patient's body and securely attached using adhesives. Once the mounting base is in position, the medical device can be freely adjusted and repositioned on the mounting base using the mechanical fastening elements. This two-stage attachment system provides both the simplicity of direct attachment (single adhesive application) and the flexibility of adjustable positioning (device repositioning on the mounting base).

AI summary
An apparatus for attaching a medical device to a subject's body, either directly to the subject's body or to an intermediary element on the subject's body. The apparatus prevents substantially any relative movement between the medical device and the subject's body. Such an apparatus comprises: (i) a back base positioned between the subjects body and a surface that the subject lies thereon, (ii) at least one set of straps connected to the back base and to at least one of the medical device and the intermediary element, and (iii) at least one set of connectors providing a connection between the at least one set of straps and one or more of the medical device, the intermediary element and the back base. The apparatus may further comprise any of pivoting connectors, a respiration sensor, and straps with a stretchable section. The apparatus may be used in combination with a sterile drape.
