Patent number: 11419987Abstract: A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber.Type: GrantFiled: April 23, 2019Date of Patent: August 23, 2022Assignee: DR.

Publication number: 20210292024Abstract: 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is introduced through the injection member and into the sterile chamber of the device, the injection member is then withdrawn from the septum, the septum reseals itself at the resulting penetration aperture, and the chamber is maintained sterile throughout the foregoing steps.Type: ApplicationFiled: March 30, 2021Publication date: September 23, 2021Inventor: Daniel Py

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.

Publication number: 20200062430Abstract: Apparatuses and methods for controlling transfer of substances to a formulation container to provide a predetermined formulation. A controller may utilize one or more of a flow time, flow rate or a volume of transfer of substance. Barcoded and RFID-containing components may be used to determine what connection or disconnection has been made, and/or time thereof. Process compliance may compare measured or determined flow or connection time, flow rate and/or the transfer volume to a predetermined time, flow rate and/or volume, and adjust one or more of the time, flow rate and/or the volume of the transfer. An optional holder or cradle is configured to receive therein a fluid transfer connector formed by the connection of first and second connector portions, each in fluid communication with a flow conduit or channel that delivers substance to or receives substance from its respective connector portion, only if the connector portions are properly connected together.Type: ApplicationFiled: September 3, 2019Publication date: February 27, 2020Inventors: Daniel Py, Debashis Sahoo, Julian V.
