Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nasal delivery systems require significant time, labor, and cost for preparing medicinal solutions, making it difficult to promptly respond to pandemics or produce small batches, and they often necessitate dedicated production facilities.
Innovation Solution
A nasal delivery device with a nozzle portion, syringe, plunger, and restoring elastic portion that allows easy delivery of medicinal solutions from a vial, coupled with an adapter for suction-type delivery, enabling efficient administration of medicinal solutions using a restoring force generated by the elastic portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a medicinal solution is filled and prepared in advance using conventional methods, then the medicinal solution can be stored in an aseptic state, but it requires significant time, labor, and cost, and necessitates dedicated production facilities
Solution Approach 1:
The device separates the storage function (vial with medicinal solution) from the delivery function (syringe and nozzle assembly). The vial remains sealed and sterile until use, while the delivery components are prepared separately and connected at the moment of administration, eliminating the need for dedicated production facilities and reducing preparation time.
Solution Approach 2:
The medicinal solution is pre-filled in the vial in an aseptic state, and the delivery device components are pre-assembled, but the actual connection and delivery are postponed until the moment of use. This allows the solution to be stored ready-to-use without requiring continuous production infrastructure.
2Reliability
If conventional filling methods are used, then the medicinal solution can be stored safely, but it takes time and effort of many personnel, making it difficult to promptly cope with pandemics or produce small batches
Solution Approach 1:
The device enables self-contained delivery where the medicinal solution is transferred from the vial to the syringe by the device itself through the pressing mechanism, without requiring external filling equipment or multiple personnel. The user simply connects the components and activates the delivery.
3Manufacturing precision
If dedicated production facilities are provided for each type of medicinal solution, then the medicinal solution can be produced with proper controls, but it requires a lot of time, labor, and cost
Solution Approach 1:
The device uses standardized components (vial, syringe, nozzle, connecting portions) that can accommodate different types of medicinal solutions without requiring dedicated production facilities for each type. The universal design allows the same device structure to be used for various medications, reducing infrastructure requirements while maintaining production control through standardized assembly procedures.

AI summary
Provided is a nasal delivery device capable of easily delivering a medicinal solution. A nasal delivery device that delivers a medicinal solution from a vial enclosing the medicinal solution, the device comprising a nozzle portion that jets the medicinal solution, a syringe connected to the nozzle portion and having a substantially hollow cylindrical shape, a plunger disposed in an insertable manner in an axial direction between an initial position and a push-in position with respect to the syringe, the plunger including a main body having a substantially columnar shape, a gasket disposed at one end of the main body, and a disk portion that applies a pressing force, the disk portion being disposed at the other end of the main body, and a restoring elastic portion that deforms and generates a restoring force as the plunger moves from the initial position to the push-in position with respect to the syringe, wherein an inner wall of the syringe and the gasket of the plunger define a first space that holds the medicinal solution in the nasal delivery device, and the medicinal solution is delivered to the first space as the restoring elastic portion is restored to an original shape by the restoring force.
