Pharmacological Bag with Luer Lock Connector for Contamination Control
Solution Overview
Problem
Current methods for preparing pharmacological solutions at desired concentrations in hospitals are impractical, error-prone, and risk microbiological contamination due to manual handling and calculation complexities, especially for alkalinized local anesthetic solutions.
Innovation Solution
A pharmacological package and a medical package, each comprising a bag with a connection element and a collection element, allowing for easy dilution and preparation of pharmacological solutions by connecting the bags through Luer Lock connectors, thereby reducing human intervention and minimizing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual manipulation and mixing of original solution with physiological solutions is performed, then pharmacological solutions can be prepared at desired concentrations, but the risk of microbiological contamination and human error increases significantly
Solution Approach 1:
The system enables self-service preparation where the pharmacist connects pre-filled bags through Luer Lock connectors, and the dilution process occurs automatically through gravity-driven flow without manual manipulation of the actual drug solution, eliminating contamination risk while maintaining concentration accuracy
Solution Approach 2:
The Luer Lock connector acts as an intermediary mechanism that enables safe connection between bags, and the physiological solution bag serves as an intermediary container that receives the drug solution through controlled connection, preventing direct manual contact with the pharmacological solution
2Measurement precision
If manual weighing and calculation procedures are used to prepare alkalinized local anesthetic solutions, then desired concentrations can be achieved, but the procedure becomes impractical and error-prone
Solution Approach 1:
The bags are pre-filled with precise concentrations of drug and physiological solution during manufacturing, eliminating the need for manual weighing and calculation at the point of use. The pharmacist only needs to connect the bags, and the correct dilution is achieved automatically
Solution Approach 2:
The manual mechanical process of weighing and calculating is replaced by a simplified mechanical connection system using Luer Lock connectors, where the preparation complexity is reduced to a simple connection action rather than complex manual procedures
3Adaptability or versatility
If human intervention is increased to manipulate solutions for preparation, then dosage can be adjusted, but the risk of microbiological contamination increases significantly
Solution Approach 1:
The system allows the pharmacist to select the appropriate pre-filled bags based on the desired dosage, and the system itself performs the mixing function through automatic flow control, minimizing human contact with the solution while maintaining dosage flexibility
Solution Approach 2:
The connection system acts as an intermediary that allows dosage adjustment through selection of different pre-filled bags rather than manual manipulation, maintaining flexibility while preventing contamination
