Abstract
A lid for closing an open ended blood chamber is provided. The lid is a one piece device forming an inlet to the blood chamber. The one piece device includes a filter media spaced apart from the inlet and wherein blood passing through the inlet passes through the filter media upon entry into the blood chamber. The filter media filters gross particulate from the blood passing therethrough. The one piece device further includes a vent port with an associated vent port cover to allow air separated to vent from the blood chamber.
Claims19
A lid for closing an open ended blood chamber, the lid comprising:
- a one piece device forming an inlet to the blood chamber, the one piece device including a filter media spaced apart from the inlet and wherein blood passing through the inlet passes through the filter media upon entry into the blood chamber with the filter media filtering gross particulate from the blood passing therethrough, the one piece device further including a vent port with an associated vent port cover to allow air to vent from the blood chamber;
- and
- wherein the filter media is a multi-planar element having a slope angled away from the inlet and toward a lateral side wall of the chamber, wherein faces of the multi-planar element are conjoined at obtuse angles, and comprise a major conjoint line sloping away from the inlet and towards the lateral side wall.
A lid for closing an open ended blood chamber, the lid comprising:
- a one piece device forming an inlet to the blood chamber, the one piece device having an outline planar shape that conforms to an outline planar shape of the blood chamber open end, the one piece device including a filter media spaced apart from the inlet and wherein blood passing through the inlet passes through the filter media upon entry into the blood chamber with the filter media filtering gross particulate from the blood passing therethrough, the filter media comprising a multi-planar element integrated into the one piece device, the one piece device further including a vent port with an associated vent port cover to allow air to vent from the blood chamber, wherein the vent port is over molded into the one piece device;
- and
- wherein the a multi-planar element comprises a slope angled away from the inlet and toward a lateral side wall of the chamber, wherein faces of the multi-planar element are conjoined at obtuse angles, and comprise a major conjoint line sloping away from the inlet and towards the lateral side wall.
A lid for closing an open ended blood chamber, the lid comprising:
- a one piece device forming an inlet to the blood chamber, the one piece device at least in part formed of an acrylic material and including a filter media at least one of heat sealed or ultrasonic welded with the acrylic material forming the lid, the filter media spaced apart from the inlet and wherein blood passing through the inlet passes through the filter media upon entry into the blood chamber with the filter media filtering gross particulate from the blood passing therethrough, the one piece device further including a vent port with an associated vent port cover to allow air separated to vent from the blood chamber, the vent port cover comprising an in molded mesh material;
- and
- wherein the filter media is a multi-planar element having a slope angled away from the inlet and toward a lateral side wall of the chamber, wherein faces of the multi-planar element are conjoined at obtuse angles, and comprise a major conjoint line sloping away from the inlet and towards the lateral side wall.
