Advanced Modular Drug Delivery System with Real-time Feedback and Wearable Integration
Legal Citation
Summary of the Inventive Concept
A next-generation drug delivery system featuring self-perforating cartridges, real-time flow rate adjustment, integrated sensing, and wearable designs, revolutionizing the precision and convenience of therapeutic substance delivery.
Background and Problem Solved
The original patent's pre-assembled cartridge design, while innovative, has limitations in terms of flow rate control and real-time monitoring. The new inventive concept addresses these limitations by introducing advanced features that enhance the precision, convenience, and wearability of drug delivery devices.
Detailed Description of the Inventive Concept
The advanced modular drug delivery system consists of a body extending from a delivery tip, which defines a cavity for retaining pre-assembled cartridges holding therapeutic substances. The cartridges are self-perforating, eliminating the need for a separate perforator. A manual activator releases a consistent flow of the substance, which can be adjusted in real-time using a feedback control system. An integrated sensing system detects the concentration of the substance in the cartridge, allowing for precise flow rate control. The system can be modular, with interchangeable cartridges holding different therapeutic substances, and can be integrated into wearable designs for extended periods of delivery.
Novelty and Inventive Step
The new claims introduce the concepts of self-perforating cartridges, real-time flow rate adjustment, and integrated sensing, which are not present in the original patent. These features, combined with the modular and wearable designs, provide a significant inventive step forward in the field of drug delivery devices.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include using different types of sensors, such as optical or electrochemical sensors, or integrating the system with artificial intelligence for predictive analytics. Variations could also include using different materials for the cartridges or the body of the delivery device, or designing the system for use in specific medical specialties, such as oncology or pediatrics.
Potential Commercial Applications and Market
The advanced modular drug delivery system has significant commercial potential in the pharmaceutical and medical device industries, particularly in the areas of personalized medicine, precision therapy, and wearable healthcare technology. Target markets could include hospitals, clinics, and pharmaceutical companies, as well as patients requiring long-term or chronic therapy.
