Reversely Pressed Medicinal Vial Sealing for Terminal Sterilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medicinal vials face challenges such as secondary pollution during injection, limited sealing reliability, and non-terminal sterilization, which hinder seamless connections between medicine manufacture, sale, and injection, particularly due to issues with ampoule, cillin, and prefilled injector vials.
Innovation Solution
The development of a reversely pressed medicinal xiding vial and injection apparatus featuring a straight cylinder vial body, integrated annular sealing gaskets, and double-ended needles, which ensures terminal sterilization and minimizes secondary pollution through a secure sealing mechanism and efficient dispensing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ampoule vial is used with flame sealing and wire-drawing sealing process, then sealing reliability is improved, but secondary pollution occurs during dispensing operation and terminal sterilization cannot be achieved
Solution Approach 1:
The invention extracts and removes the problematic components (grinding wheel, flame sealing apparatus) that cause secondary pollution, replacing them with a pre-sealed ampoule vial system that eliminates the need for on-site breaking and grinding operations, thereby preventing glass debris contamination
Solution Approach 2:
The ampoule vial is pre-sealed with high-reliability sealing before leaving the manufacturing facility, and the breaking operation is pre-planned to occur only at the moment of use through simple mechanical force rather than requiring grinding wheels, thus preventing secondary pollution from grinding debris
2Ease of operation
If cillin vial is used with rubber plug sealing, then ease of operation is improved, but secondary pollution occurs during injection due to air suction and the piston is not sealed with aluminum cap by pressure causing piston to fall off during high temperature sterilization
Solution Approach 1:
The invention employs a disposable ampoule vial system where the entire vial is discarded after single use, eliminating the need for complex sealing mechanisms like rubber plugs and aluminum caps that can fail during sterilization, while also preventing secondary pollution from repeated handling and air suction operations
3Reliability
If card vial is used with rubber piston sealing, then terminal sterilization is achieved, but device complexity increases due to high sealing reliability technology requirements and manufacture cost increases
Solution Approach 1:
The invention extracts and removes the complex rubber piston sealing mechanism from the system, replacing it with a simpler pre-sealed ampoule vial system that achieves terminal sterilization through the inherent seal integrity of the pre-sealed ampoule, thereby reducing device complexity while maintaining sterilization capability
Solution Approach 2:
Instead of using a complex movable piston system that requires high sealing reliability technology, the invention inverts the approach by using a fixed, pre-sealed ampoule vial where the sealing is accomplished during manufacturing through flame and wire-drawing processes, eliminating the need for complex sealing mechanisms during use
4Ease of operation
If prefilled injector is used with integrated needle head, then ease of operation is improved and cross infection is prevented, but package materials cost increases and adaptability to non-terminal sterilization products is limited
Solution Approach 1:
The invention creates a universal ampoule vial system that can accommodate various types of medicines (heat-resistant and heat-sensitive) through its simple, adaptable structure, allowing the same basic system to be used across different medical applications without requiring specialized components like pre-filled injectors with integrated needle heads

AI summary
A medicinal xiding vial, and a dispensing apparatus and an injection apparatus thereof, comprise a reversely pressed medicinal xiding vial, a reversely pressed dispensing apparatus and a reversely pressed injection apparatus thereof, a general medicinal xiding vial, and a general injection apparatus. The reversely pressed medicinal xiding vial comprises a vial body whose inner wall is a straight cylinder. A first piston is disposed on a position close to the vial opening of the vial body. A blind hole is disposed at the center of an outer bottom surface of the first piston. The vial opening is provided with an outer edge, and a seal cap is fixed on the out edge to prevent the first piston from falling off. In combination with the dispensing apparatus and the injection apparatus thereof, the medicinal xiding vial can solve the problem of secondary pollution during medicine dispensing and injection.
