Abstract
A sealed container opening, intended for fluid communication with a container for storing medical fluids, comprising a tubular sleeve-formed part (22, 22A) having a resilient pierceable stopper (24, 24A) inserted in its mouth (21, 21A) and a covering sealing device (10, 10A). The sealed container opening contains the same autoclavable polyolefinic material as the container. All parts of said container opening, exposed to the fluid or fluid handling devices are sterilized in a single process by means of steam transferred to these parts during its autoclavation. Saddle formed port systems attachable to a flexible containers are also disclosed.
Claims11
An autoclavable container for storage of medical fluids, comprising:
- at least one container opening comprising a tubular sleeve interconnected with the container for fluid communication with the container, a resilient pierceable stopper arranged in a mouth of the sleeve, and a seal arranged on the sleeve for sealing the mouth of the sleeve and comprising a peelable foil capable of being penetrated by sterilizing steam to sterilize a space between the foil and the stopper, wherein all elements of the opening exposed to fluid contained in the container or fluid handling devices are sterilized in a single process by steam transferred to all elements of the container opening during autoclavation, wherein the container is recyclable in a single process without dismemberment.
A saddle-formed port system attachable to a flexible container of a polymeric material for establishing fluid communication with a medical fluid stored in the container, comprising:
- at least one container opening for introducing an additional fluid to be mixed with the medical fluid;
- at least one container opening connectable to a fluid transferring device;
- wherein each container opening comprises a tubular sleeve interconnected with the container for fluid communication with the container, a resilient pierceable stopper arranged in a mouth of the sleeve, and a seal arranged on the sleeve for sealing the mouth of the sleeve and comprising a peelable foil capable of being penetrated by sterilizing steam to sterilize a space between the foil and the stopper, wherein all elements of the openings exposed to fluid contained in the container or fluid handling devices are sterilized in a single process by steam transferred to all elements of the container opening during autoclavation.
A sealed opening for a container that stores medical fluids, comprising:
- a tubular sleeve for interconnection with the container for fluid communication with the container;
- a resilient pierceable stopper arranged in a mouth of the sleeve;
- and
- a seal comprising a peelable foil arranged on the sleeve for sealing the mouth of the sleeve, the foil being penetrateable by sterilizing steam to sterilize a space between the foil and the stopper;
- wherein all elements of the opening comprise the same autoclavable polyolefin containing material as the container and wherein all elements of the sealed opening exposed to fluid contained in the container or fluid handling devices are sterilized in a single process by steam transferred to all elements of the container opening during autoclavation.
