Pre-mixed Spinal Anesthesia Formulation Reduces Preparation Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional processes for preparing spinal anesthetic formulations are time-consuming, prone to human error, wasteful, and risky due to the need for on-site mixing and measurement during urgent medical procedures.
Innovation Solution
A pre-mixed injectable medical formulation for spinal anesthesia is prepared and packaged in advance in a single container, containing a local anesthetic, short-acting and long-acting opioids, and optional adjuvants, which is then transported to a medical facility for immediate use, minimizing on-site preparation and reducing the risk of error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If spinal anesthetic formulations are prepared on-site during urgent medical procedures, then the formulation can be customized for specific procedures, but the preparation process is time-consuming and prone to human error
Solution Approach 1:
The patent applies preliminary action by pre-mixing spinal anesthetic formulations containing specific combinations of local anesthetics and opioids in predetermined ratios before the medical procedure. This allows the formulations to be ready for immediate use during urgent procedures, eliminating time-consuming on-site preparation while maintaining procedure-specific customization through selection of appropriate pre-mixed formulations.
2Adaptability or versatility
If spinal anesthetic formulations are prepared on-site during urgent medical procedures, then the formulation can be customized for specific procedures, but the risk of human error increases
Solution Approach 1:
The patent eliminates human error in measurement and mixing by pre-preparing formulations with exact concentrations and ratios of local anesthetics and opioids. The pre-mixed formulations are packaged in ready-to-administer containers, removing the need for on-site measurement and mixing operations that are prone to human error during urgent procedures.
Solution Approach 2:
The patent implements self-service by designing the anesthetic system to be self-contained and self-regulating. The pre-mixed formulations include precise drug combinations in sealed containers that require no additional manipulation, allowing the formulation to 'serve itself' by maintaining correct concentrations and ratios without human intervention during administration.
3Adaptability or versatility
If spinal anesthetic formulations are prepared on-site during urgent medical procedures, then the formulation can be customized for specific procedures, but the process is wasteful
Solution Approach 1:
The patent reduces medication waste through preliminary action by preparing exact dosages in advance and packaging them in single-use containers. This eliminates the need to discard partially used vials or adjust concentrations during procedures, as each pre-mixed formulation contains the precise amount needed for the specific procedure.

AI summary
A combination of a container and an injectable medical formulation for use in spinal anesthesia as part of a medical procedure includes the injectable medical formulation including a pre-determined amount of a local anesthetic; a pre-determined amount of a short-acting opioid, the short-acting opioid being one of fentanyl or sufentanil; and a pre-determined amount of a long-acting opioid, the long-acting opioid being one of morphine and hydromorphone. The container is a single apparatus in which the injectable medical formulation is packaged and stored as a single dose prior to the medical procedure. The injectable medical formulation is packaged and stored within the container prior to a window of imminency of the medical procedure.
