Latest Patents

Iwase's latest patents focus on the design and functionality of indwelling needles. The first patent describes an indwelling needle that includes a cylindrical body, a needle with a sharp edge at its tip, and a cylindrical hub that retains the proximal end of the needle. This design features a protective cover that is moveable along the main body and a spring that is elastically installed between the hub and the protective cover. The configuration allows for a first engaging portion of an actuating lever to engage with the protective cover, enabling the first retention mechanism to retain the indwelling needle in a use state. This innovative design reduces the length of the member contacting the patient, enhancing safety during use.

The second patent also describes an indwelling needle composed of a body with a closed end and a sharp-edged needle at the tip. This design includes a tubular hub that retains the proximal end of the needle and is slidable along the main body. The protective cover is also slidable and projects from the main body. A spring is fitted between the body and the protective cover, allowing for modifications to the length of the indwelling needle in an operative state, thereby inhibiting potential injury to the patient.
