Latest Patents

David L. Jones's latest advancements include two noteworthy patents:

1. **Chambered Septum** - This innovative design features a septum that contains at least one internal chamber along its central axis. The chamber functions as a relief space intended for the sealing sections of the septum to deform as a needle passes through. By incorporating this chamber, the design reduces both surface area contact and friction between the septum and needle, which ultimately leads to diminished septum tearing and the production of particulate matter resulting from abrasion.

2. **Duckbill Septum** - This patent introduces a septum equipped with a duckbill valve assembly that incorporates multiple elastomeric ribs extending from the body of the septum to the assembly itself. Upon insertion into an injection port cavity, the interference fit between the body of the septum and the cavity transmits force through these ribs to the duckbill valve assembly. Specifically designed to reversibly collapse at a hinge point during needle insertion, the ribs assist in centering the needle. This innovative feature reduces wear on the duckbill valve assembly by mitigating the concentration of compressive forces, allowing high performance at various inlet pressures.
