Summary of the Inventive Concept

A device and method for closing syringe bodies adapted for specific, narrow markets or unique operational environments, such as high-security needs, disaster relief, extreme weather conditions, remote areas, and high-altitude environments.

Background and Problem Solved

The original patent relates to a device for manually inserting a plunger-type stopper made of elastomer into a syringe cylinder. However, the existing methods are limited to general applications and do not cater to specific, demanding environments. The new inventive concept addresses this limitation by adapting the device for specialized environments, ensuring sterile, efficient, and reliable syringe filling in various contexts.

Detailed Description of the Inventive Concept

The new inventive concept comprises devices and methods for closing syringe bodies in specialized environments. In high-security environments, the device operates in a sterile glove box. For disaster relief scenarios, the method involves aseptically filling syringes in a mobile laboratory. In extreme weather conditions, the device features a hand-crank generator-powered moving device. For remote areas, the system includes a satellite communication system for transmitting data related to the filling process. In high-altitude environments, the method involves filling the syringe cylinder with a medicament in a pressurized chamber. Each adaptation ensures the device's effectiveness in its respective environment.

Novelty and Inventive Step

The new claims introduce novel adaptations of the original device, specifically designed for high-security needs, disaster relief, extreme weather conditions, remote areas, and high-altitude environments. These adaptations provide a non-obvious, inventive step beyond the original patent, as they address unique challenges and requirements in each specialized environment.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include adaptations for other specialized environments, such as space exploration or underwater operations. Variations could also involve different materials, shapes, or sizes of the device components to accommodate specific requirements. Furthermore, the device could be integrated with other systems, such as automated filling machines or robotic arms, to enhance its functionality and efficiency.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including pharmaceuticals, biotechnology, disaster relief, and aerospace. The device's adaptability to different environments makes it an attractive solution for companies operating in these specialized markets. The market potential is substantial, as the device addresses specific needs and challenges in each environment, ensuring reliable and efficient syringe filling.
