Birthing Bed Limb Support Release for Stable Multi-Axis Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing birthing bed accessories fail to adequately support patients' limbs during obstetric labor and delivery, particularly in reclining positions, where knee flexure is necessary for optimal delivery positioning.
Innovation Solution
A limb support system for birthing beds that includes adjustable foot supports and leg supports, capable of pivoting on both vertical and horizontal axes, with locking mechanisms that can be released by a caregiver for precise positioning, and a ball-lock mechanism for secure leg support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a limb support apparatus is designed with fixed positioning to ensure stability during delivery, then reliability is improved, but adaptability deteriorates because the support cannot be adjusted to different patient positions and delivery requirements
Solution Approach 1:
The limb support apparatus employs a dynamic positioning system with multiple axes of rotation (vertical and horizontal axes) that allows the support to be adjusted to different angles and positions. The support can be rotated and tilted to accommodate various patient positions during labor and delivery, transforming a static structure into a dynamically adaptable one that maintains reliability through controlled movement rather than fixed positioning.
2Reliability
If a limb support apparatus incorporates multiple locking mechanisms to secure positioning, then reliability is improved, but device complexity worsens due to the number of components required
Solution Approach 1:
The patent combines multiple locking functions into a single integrated locking mechanism that can secure the limb support apparatus in multiple positions simultaneously. Rather than having separate locks for each axis of rotation, the design merges the locking functions so that one mechanism can engage both vertical and horizontal positioning, reducing component count while maintaining secure positioning through a unified locking system.
3Ease of operation
If a limb support apparatus is designed with easy adjustment mechanisms for frequent repositioning, then ease of operation is improved, but reliability deteriorates due to potential loosening or failure of adjustment mechanisms
Solution Approach 1:
The limb support apparatus incorporates self-locking features that automatically engage and secure the support in its adjusted position without requiring additional fastening actions. The mechanism is designed so that the act of adjustment itself triggers the locking function, where the position of the support automatically engages locking surfaces or spring-loaded locks that hold the position securely, eliminating the need for separate locking steps while ensuring stability.

AI summary
A limb support coupled to a patient-support apparatus comprises a frame having a pair of locks to block vertical and horizontal pivoting of the limb support in relation to the patient-support apparatus. The lock release actuator is configured to be coupled to the frame to simultaneously unlock both the vertical and horizontal rotation locks. The limb support includes a stowable leg support configured to provide support to the leg of a patient during obstetric delivery.
