A circular roller clamp assembly includes a semi-circular housing configured to receive a portion of an IV tube and a roller coupled to an arm, the roller configured to be movably received by a guide groove disposed in the semi-circular housing. The roller clamp assembly is configured to regulate a flow rate of fluid flowing through the IV tube based on engagement of the roller with the IV tube via circumferential movement of the roller along the guide groove. IV sets with circular roller clamp assemblies and methods of operating circular roller clamp assemblies are also provided.

Circular roller clamp assembly

IV stand assemblies are provided that include a base, a stand, a platform and a motorized pole assembly having a housing, a pole and a drive. The drive moves the pole to extend and retract the pole relative to the housing. A weight measurement assembly measures weight of a fluid within a fluid container hanging from the IV stand assembly. IV stand assemblies with a pulley/belt assembly and methods of operating IV assemblies are also provided.

Self-adjusting IV stand

A needleless connector includes a housing having a central longitudinal axis, a body portion, and a base portion. The body portion includes an inner surface forming an internal cavity, and a first port forming a first fluid passage to the housing cavity. The base portion includes a top end section and a bottom end section. The top end section has a protrusion, and the bottom end portion has a second port forming a second fluid passage to the housing cavity. The needleless connector further includes a valve having a wall with an inner surface forming a valve cavity. The valve is coupled with the housing such that the protrusion is positioned in the valve cavity, and a proximal end of the protrusion is spaced apart from a proximal end of the valve cavity.

Needleless connector with valve pivot support

Syringe assemblies are described herein. A syringe assembly includes an assembly housing, a first syringe, a second syringe, and a connecting gear. The first syringe is disposed within the assembly housing. Each plunger is movable within the respective syringe cavity and defines a respective chamber in the respective syringe cavity, wherein the respective chamber is in fluid communication with the respective syringe port, the respective plunger comprising a respective gear rack extending longitudinally along the respective plunger. The connecting gear is rotatably coupled to the assembly housing. The connecting gear is configured to be in meshed engagement with at least one of the first gear rack and the second gear rack of the syringes.

Sequenced syringe assembly

Drip chambers are described herein. A drip chamber comprises an inlet, an outlet, and a chamber body. The chamber body defines a chamber volume in fluid communication with the inlet and the outlet. The chamber body is movable between a collapsed configuration having a first volume and an expanded configuration having a second volume. The second volume is larger than the first volume, and the chamber body is configured to be moved from the collapsed configuration to the expanded configuration to draw in a medical fluid from the inlet into the chamber volume to prime the drip chamber.

Expandable drip chamber

A needleless access connector having an access port and a sustained release antimicrobial coating only on a top surface of the access port is disclosed. The top surface of the access port can be defined by a top surface of a proximal end of a housing and a top surface of a head portion of a compressible valve disposed within an internal cavity of the housing. In certain embodiments of the present disclosure, the sustained release antimicrobial coating is on: (i) the top surface the proximal end of the housing, or (ii) the top surface of the head portion of the compressible valve, or (iii) the sustained release antimicrobial coating is only on both the top surface the proximal end of the housing and the top surface of the head portion of the compressible valve.

Antimicrobial coating extending performance of needleless connector

A circular roller clamp assembly includes a semi-circular housing configured to receive a portion of an IV tube, a motor and a motor arm coupled to the motor. A roller is coupled to the roller arm, the roller movably received by a guide groove disposed in the semi-circular housing. A flow rate of fluid flowing through the IV tube is regulated based on roller impingement of the IV tube against a tube channel in the guide groove via circumferential movement of the roller along the guide groove. IV sets with circular roller clamp assemblies and methods of operating circular roller clamp assemblies are also provided.

A valve including an antimicrobial agent can be used with needleless access connectors. The valve can have an insert that includes an antimicrobial coating thereon and/or the valve can have physical features, such as a series of tunnels or groves or a patterned surface, containing an antimicrobial formulation and/or the valve can be made of a material that includes an antimicrobial agent.

Vented syringes are described herein. A vented syringe includes a syringe body and a plunger body. The syringe body defines a syringe cavity. The plunger body is at least partially disposed within the syringe cavity. The plunger body includes an air intake channel defined within the plunger body. The vented syringe further includes a plunger seal that is sealingly engaged with the syringe cavity to cooperatively define a syringe volume. The vented syringe further includes a one-way valve in fluid communication with the air intake channel and the syringe volume, wherein the one-way valve is configured to prevent fluid flow from the syringe volume to the air intake channel and permit fluid flow from the air intake channel to the syringe volume.
