Keep vein open (KVO) infusion flow control devices are provided. The KVO infusion flow control device couples to intravenous (IV) tubing and includes a flow controller that provides a full open fluid flow rate through an outlet portion of the IV tubing when the flow controller is in an open position, and a KVO fluid flow rate through the outlet portion of the IV tubing when the flow controller is in a KVO position. Visual indicators are disposed on the KVO infusion flow control device.

A medical connector includes a tubular male connector unit, an engaging unit arranged on an outer side of the male connector unit in a radial direction of the male connector unit, at least a part of the engaging unit being elastically deformable inward in the radial direction, a locking unit movable between a first position and a second position in which at least a part of the engaging unit is elastically deformed inward in the radial direction relative to the first position, and a blocking mechanism configured to block the locking unit from moving from the first position to the second position in a predetermined state.

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 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.

Devices and methods for delivering an antimicrobial composition to a medical device to prevent infection and microbial ingress in medical devices. An embodiment of the device includes a male connector with a distal tip and a recess at the distal tip configured to deliver an antimicrobial composition into solution within a cavity formed by the recess. The surface of the recess includes an antimicrobial composition. In certain implementations, the antimicrobial composition contains chlorhexidine acetate.

An infusion system includes a primary delivery device, a secondary delivery device, an ancillary device, and a manifold. The manifold includes a primary connection port fluidly coupled with the primary delivery device. A delivery connection port in fluid communication with the primary connection port is fluidly coupled with the ancillary device. A secondary connection port fluidly coupled with the secondary delivery device is in fluid communication with the primary connection port. The primary connection port is operable to permit bidirectional flow so that fluid flows from the primary delivery device through the primary connection port and through the delivery connection port to the ancillary device, and from the secondary delivery device through the secondary connection port and through the primary connection port to be received by the primary delivery device.

A connector connection indicator is mounted in a Luer male connector, or in a Luer female connector, to indicate proper mating of the two Luer connectors. The connection indicator may be or include a light source, a sound producing device (e.g., buzzer), a switch, a tactile connection indicator or an electronic chip. The electronic chip may be interposed between two conductive elements that are mounted in the Luer female connector. When the two Luer connectors are properly engaged, the electronic chip is powered via two electrical terminals. While the electronic chip is powered up it communicates with an external system via two electrical terminals. The external system interprets the communication with the electronic chip as an indication to proper engagement of the two Luer connectors. Some of the connection indicators may be mounted on a circuit board that is embedded in a void in the Luer male connector.

An implantable percutaneous fluid delivery device is described that includes a subcutaneous base portion having one or more ports for supplying fluid to one or more implanted catheter devices and a percutaneous portion including an extracorporeal surface. The one or more ports of the subcutaneous base portion are accessible from the extracorporeal surface of the percutaneous portion. The subcutaneous base portion is at least partially insertable into a complementary recess formed in a bone, the subcutaneous base portion including one or more features for gripping the internal surface of such a complementary recess thereby directly anchoring the subcutaneous base portion to the bone. The device may be used to route fluid to neurosurgical catheters optionally via a router unit.
