Implantable Sensor Inserter Locking Mechanism for Stable Transport and Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The detachable connection between existing monitoring units and inserting apparatuses for implantable analyte sensors is unstable, leading to a low success rate of implantation due to potential detachment during transportation or use.
Innovation Solution
An inserting apparatus with a housing, monitoring unit, and insertion unit, featuring a driving assembly and puncture assembly, includes a locking member that maintains a locked state during transportation and transitions to an unlocked state for smooth separation after implantation, enhancing connection stability and simplifying operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable connection is used between the monitoring unit and inserting apparatus, then ease of operation is improved, but reliability deteriorates due to potential detachment during transportation or use
Solution Approach 1:
The locking member transitions between a locked state (abutting the limiting portion) and an unlocked state (separated from the limiting portion), enabling the connection to dynamically adapt between secure attachment during transportation and easy separation after implantation
Solution Approach 2:
The locking member is pre-configured in the locked state to maintain connection stability during transportation and before use, and is designed to transition to the unlocked state after implantation to enable smooth separation
2Reliability
If a locking mechanism is added to improve connection stability, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: the locking member with locked and unlocked states, and the limiting portion on the monitoring unit, allowing independent optimization of each component
Solution Approach 2:
The locking member automatically transitions between locked and unlocked states based on the implantation process, eliminating the need for complex external control mechanisms or additional actuators

AI summary
An inserting apparatus for implantable sensor placement includes a housing, a monitoring unit, and an insertion unit. The monitoring unit is arranged in the housing and has a limiting portion. The insertion unit includes a driving assembly and a puncture assembly. The driving assembly is configured to drive the puncture assembly and the monitoring unit to move and includes a locking member configured to be engaged with the limiting portion. The locking member has a locked state in which the locking member abuts with the limiting portion and an unlocked state in which the locking member is separated from the limiting portion.
