Medical Sheet Transfer Instrument With Integrated Moisture Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transfer instruments for medical sheets require manual manipulation with forceps, which can lead to inefficient transfer and risk breakage of the medical sheet during application to a treatment site.
Innovation Solution
A transfer instrument with a first and second carrier member and a liquid supply mechanism, allowing the medical sheet to be transferred without additional devices and maintaining moisture to prevent breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual manipulation with forceps is used to transfer the medical sheet, then the transfer can be performed, but the transfer efficiency is low and the medical sheet may break
Solution Approach 1:
A second carrier member is introduced as an intermediary device between the first carrier member and the medical sheet. The second carrier member slides on the support portion to transfer the medical sheet, eliminating the need for direct manual manipulation with forceps and reducing the risk of breakage while improving transfer efficiency
Solution Approach 2:
The support portion is designed with self-adhesive properties that allow it to automatically hold and release the medical sheet during the transfer process. The medical sheet adheres to the support portion when placed and releases when the second carrier member slides, enabling automated transfer without manual intervention
2Ease of operation
If the medical sheet is exposed outside the outer cylinder during transfer, then the transfer to treatment site is enabled, but the medical sheet may dry out and break
Solution Approach 1:
A liquid supply portion is integrated into the first carrier member that automatically supplies liquid to the medical sheet during the transfer process. This hydraulic mechanism prevents the medical sheet from drying out while it is exposed outside the outer cylinder, maintaining its integrity throughout the transfer operation
Solution Approach 2:
The liquid supply mechanism is activated before the medical sheet is fully exposed during transfer. By preliminarily supplying liquid to maintain moisture, the medical sheet is prepared to withstand the exposure conditions without drying or breaking
3Volume of moving object
If the support portion is retracted into the outer cylinder, then the instrument profile is reduced, but the medical sheet must be curved and deformed
Solution Approach 1:
The support portion is designed as a dynamic structure that can change its shape between extended and retracted states. When retracted, it naturally curves and deforms to fit within the outer cylinder's limited space, while maintaining its functional integrity for subsequent medical sheet transfer operations
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 instrument efficiently transfers medical sheets to treatment sites while preventing drying and breakage by using a liquid supply mechanism to maintain moisture, enhancing the sliding process.
Implementation Method 1
a liquid supply portion capable of supplying a liquid into the first shaft in order to supply the liquid toward the support surface through a distal-end opening of the first shaft
Implementation Method 2
when the distal portion of the second carrier member is slid on the unfolded support portion, the sliding of the distal portion of the second carrier member on the support portion can be improved

AI summary
A transfer instrument includes a first shaft having a tubular shape, a second shaft movably inserted through the first shaft, and a liquid supply portion capable of supplying a liquid toward a first support surface of a first support portion via a distal-end opening of the first shaft.
