The system also includes a connection portion having a distal end and a proximal end, the connection portion including a connector interface disposed at the distal end and a fluid path member fluidly coupled to the connector interface and configured to be coupled to the fluid connector component of the fluid access assembly, wherein the fluid path member is configured to reduce hemolysis of a blood sample passing therethrough.

A filling aid. The filling aid includes a locking portion including a groove feature; and a locking feature having a locked and an unlocked position; and a filling syringe holder slidably attached to the locking portion, the filling syringe holder including a filling needle cradle portion having a tongue feature; and a needle housing portion comprising at least one tab having a starting position and a filling position, wherein the groove feature configured to accommodate the tongue feature, and wherein the locking feature interact with the filling syringe holder wherein when the locking feature moves from the locked position to the unlocked position the needle housing portion moves from the starting position to the filling position.

Improved apparatus for use with medication in fluid form, which is particularly beneficial for medications having a relatively high viscosity. The disclosed syringe adapter has an opening that is relatively large, as compared to a conventional needle, and thus affixing the disclosed syringe adapter to a syringe improves syringeability of higher-viscosity medications. Some embodiments feature a lateral extension that prevents inserting the syringe adapter too far into a medicine bottle, and some embodiments feature a component that assists in firmly grasping. When the disclosed syringe adapter is affixed to a pistol-grip or tab-handled syringe, the medication withdrawn into the pistol-grip syringe can be more easily administered from the syringe barrel. In some embodiments, the syringe adapter will be replaced with a needle prior to injecting the medication, while in some other embodiments, the needle is affixed to the in-place syringe adapter for the injection. In yet other embodiments, the needle is affixed to a needle holder that, in turn, is affixed to the in-place syringe adapter for the injection.

A monitoring device may include a housing, which may include a distal end, a proximal end, and a fluid pathway extending through the proximal end and distal end. The distal end may include a connector configured to couple to a catheter assembly. The monitoring device may include one or more sensors disposed within the fluid pathway. The sensors may facilitate identification of an occlusion within the catheter assembly.

Couplers are described herein. A coupler includes a coupler body, a plurality of first retaining fingers, and a plurality of second retaining fingers. The coupler body includes a first end and a second end, and defining a cavity, the cavity configured to receive a first connector and a second connector. The plurality of first retaining fingers are configured to engage against a collar of the first connector to prevent axial motion of the first connector relative to the coupler. The plurality of second retaining fingers are configured to engage against a shoulder of the second connector with a retention force, and release the second connector by radially expanding in response to a pullout force exerted on the second connector exceeding the retention force.

A connection mechanism 242 of the present invention is configured such that, in a state where an inclined end surface 536 of a male connection portion 500 is brought into contact with a protruding portion 618 of a female connection portion 600, by moving the male connection portion 500 toward the female connection portion 600, the male connection portion 500 rotates and the protruding portion 618 is inserted into a guide portion 534 and a connector 532 is connected to an adapter 610. The lock mechanism 243 is configured such that the protrusion 704 of the male lock portion 700 comes in contact with a wall 858 of a circumferential recess 842 disposed in a proximal cylindrical member 806 of the female lock portion 800, and in this state, the proximal cylindrical member 806 is further moved toward a proximal fixing member 804 against an urging force of a spring 854, and then the male lock portion 700 is rotated to move to a space 856 of the circumferential recess 842.

A flow restriction device may include a male luer connector portion and a female luer connector portion. The male luer connector portion can define a cavity and a first lumen in fluid-flow continuity with the cavity. The female luer connector portion defines a second lumen and an extension in fluid-flow continuity with the second lumen. The extension includes a first end, a second end, an outer surface, and a channel. The channel is defined on the outer surface. The channel is helically disposed around the outer surface of the extension and extends between the first and second ends. The extension is configured to be at least partially disposed within the cavity. The channel and the inner surface of the cavity define a fluid passage in fluid-flow continuity with the first lumen and the second lumen.

A flow restriction device may include a male luer connector portion, a female luer connector portion, a tube, and an overmolded body portion. The male luer connector portion defies a first lumen. The female luer connector portion defines a second lumen. The tube defines a third lumen. The third lumen is in fluid communication with the first lumen and the second lumen. The third lumen has a diameter less than 0.025 inches. The overmolded body portion is formed around the tube.

A filter adaptor includes a body that defines an internal passageway disposed between an inlet and an outlet, the passageway configured to permit passage of a fluid in a first direction defined by the inlet and the outlet; and a filter disposed within the passageway and oriented to define a volumetric direction that is different than the first direction. Another filter adaptor includes a body that defines an internal passageway disposed between an inlet and an outlet, and a filter disposed within the passageway, wherein the filter comprises a gelling absorbent material that, when in a dry state, is permeable to gas and that, when contacted by an aqueous fluid, converts to a gel. Such filter adaptors may be used for negative pressure wound therapy, dressing, or as syringe filters.

A catheter adapter may include a catheter adapter body and a catheter adapter channel formed within the catheter adapter body. The catheter adapter body may include a proximal end, a distal end, an inferior surface, and a superior surface. The inferior surface of the catheter adapter body may be configured to abut against a surface area of a patient's skin, and an angle formed between the surface area of the patient's skin and a longitudinal axis of the catheter adapter channel may be greater than 4 degrees.
