Patent number: 10688020Abstract: A septum is penetrable by a needle for decontamination by physical interaction. The septum can include a peripheral portion, an exterior surface, and an interior surface. A penetration portion extends between the exterior and interior surfaces, is spaced inwardly of the peripheral portion, and is penetrable by the needle or other penetrating element. A flex portion is located between the penetration portion and the peripheral portion. A thicker portion extends between the flex portion and the penetration portion, and defines an increased thickness between the exterior and interior surfaces relative to the flex portion. The flex portion is flexible inwardly relative to the peripheral portion during penetration of the penetration portion by a needle or other penetrating element. The penetration portion physically interacts with and decontaminates the needle when it penetrates the septum. The septum may also reduce or prevent retrograde contamination when the needle is withdrawn.Type: GrantFiled: April 3, 2018Date of Patent: June 23, 2020Assignee: DR.

Patent number: 10202214Abstract: An injection member penetrates an elastic septum of a device defining a sealed, empty, sterile chamber in fluid communication with the septum. During penetrating, an annular interface is formed between the septum and the injection member extending axially between a penetration point on an interior surface of the septum in fluid communication with the sterile chamber, and an exterior surface of the septum engaging the injection member. The injection member is de-contaminated by (i) friction between the septum and injection member at the annular interface, and (ii) elongation of the septum at the annular interface. A substance is introduced through the injection member and into the sterile chamber of the device, the injection member is then withdrawn from the septum, the septum reseals itself at the resulting penetration aperture, and the chamber is maintained sterile throughout the foregoing steps.Type: GrantFiled: February 16, 2017Date of Patent: February 12, 2019Assignee: DR.
