Aseptic Fluid Dispensing Device with Integrated Syringe Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for dispensing pharmaceuticals under aseptic conditions, such as the Onpro™ drug pump, are complex, costly to manufacture, and prone to contamination during fluid transfer, requiring medical personnel and multiple parts, which complicates patient administration and increases risk.
Innovation Solution
A device with a delivery mechanism that generates underpressure to extract fluid from a syringe directly to a dispensing opening, eliminating the need for additional containers and using a coupling element with a pierceable septum for hygienic connection, integrated with a holder for secure syringe placement, reducing parts and manufacturing costs while ensuring aseptic handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drug pump with multiple individual parts is used to dispense fluid under aseptic conditions, then the reliability of aseptic dispensing is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the container, delivery device, and coupling element into a single integrated drug delivery device. The container is directly coupled to the delivery device, eliminating the need for separate components that would require assembly. This integration maintains aseptic reliability while reducing device complexity and manufacturing cost.
Solution Approach 2:
The device is designed to work with traditional syringes that patients already possess, allowing the syringe to serve dual purposes: as a temporary storage container and as the delivery mechanism. This universality reduces the number of specialized components needed in the drug pump system.
2Reliability
If the solution is transferred from a prefilled syringe into a drug pump through a small septum, then the aseptic containment is improved, but the ease of operation deteriorates requiring medical personnel
Solution Approach 1:
The device enables patients to load their own syringes into the delivery system without requiring medical personnel. The coupling element is designed to automatically pierce the syringe septum and establish fluid connection when the syringe is inserted, allowing patients to perform the loading themselves while maintaining aseptic conditions.
Solution Approach 2:
The coupling element acts as an intermediary between the syringe and the delivery device. It automatically pierces the syringe septum and establishes a fluid-tight connection, mediating the transfer process in a way that maintains aseptic containment while simplifying operation for patients.
3Adaptability or versatility
If multiple individual parts are used in the drug pump system, then the adaptability for different uses is improved, but the manufacturing cost and production complexity increase
Solution Approach 1:
The patent merges the container, coupling element, and delivery device into a single integrated unit that can be manufactured as one component. This reduces the number of parts that need to be produced, assembled, and quality-checked, thereby lowering manufacturing costs while maintaining versatility through the universal coupling design.
4Productivity
If the fluid is transferred through multiple components and containers, then the delivery control is improved, but the contamination risk increases
Solution Approach 1:
The invention extracts the fluid directly from the syringe into the patient's body through the integrated delivery device, eliminating intermediate transfer steps and containers. This direct path removes potential contamination points while maintaining precise delivery control through the delivery device's mechanism.
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 solution simplifies the administration process, reduces contamination risk, and allows non-medically trained individuals to use the device safely, lowering production costs and streamlining regulatory approvals by integrating a traditional syringe for both injection and device use.
Implementation Method 1
the delivery device generates an underpressure at the syringe, as a result of which the content of the syringe is suctioned from the latter
Implementation Method 2
the content of the syringe is suctioned from the latter and, under the effect of the suction force, the plunger of the syringe moves
