Connector system for medical fluid administration

摘要

A connector system for medical fluid administration has a female connection member, which can act as an access port for a container of medical fluid, and a male connection member, for accessing the container of medical fluid. The female connection member defines a sheath for receiving a portion of the male connection member and this sheath is spanned at one end by a septum, which acts to close the container of medical fluid. A lumen is defined through the male connection member to allow passage of fluid therethrough. The septum has a central region and a peripheral region, the central region being of substantially greater thickness than the peripheral region. The male connection member comprises means for rupturing the peripheral region of the septum when it is received in the female connection member to form a connection.

主权项

1. A connector system for medical fluid administration, comprising:
a male connection member including a body comprising a distal portion terminating in a distal end and a proximal portion terminating in a proximal end, a lumen being defined through the body for passage of liquid from the distal end to the proximal end; and a female connection member including a sheath that receives the distal portion of the male connection member, a distal end of the sheath being spanned by a septum having a central region and a peripheral region surrounding the central region, wherein the central region of the septum has a thickness that is between 1.5 and 400 times thicker than the peripheral region of the septum surrounding the central region, wherein the distal end of the male connection member includes at least one projection that is configured to rupture the peripheral region of the septum when the male connection member is received in the female connection member to form a connection so that a portion of the central region is permanently separated from the peripheral region and another portion of the central region remains attached to the peripheral region when ruptured; the distal end has a surface that is substantially perpendicular to an axis of the lumen, the at least one projection projects from the surface, and the at least one projection is offset from the axis so that the at least one projection is aligned for engagement with the peripheral region of the septum when the male connection member is received in the female connection member, and in which the male connection member is a giving set spike for the administration of medical fluids, and the female connection member is configured for connection to, and forms an access port into, a medical fluid container.
