A chest valve including: a housing including an inlet configured to connect to a chest tube, an outlet and a fluid passage from the inlet to the outlet; and a one-way valve within the housing and included in the flow passage, wherein the one-way valve includes: (i) a first tubular strip wherein having an internal air passage and a first layer defining the air passage, wherein the first layer has a first thickness and the internal air passage of the first tubular strip is included in fluid passage of the housing; and (ii) a second tubular strip wherein having a second layer with a second thickness with a second thickness greater than the first thickness, wherein an outer surface of the second tubular strip is adjacent and overlaps an outer surface of the first tubular strip.

Described is a catheter patency maintenance device comprising of a flush syringe, an elongate plunger rod with a stopper slidably positioned within the barrel, a cap, disinfectant and a valve movable between an open position and a closed position. The valve may include a valve stem and/or openings in the valve to permit fluid flow. Methods of using the flush syringe assemblies are also described.

A coupler of a valve assembly for coupling a flow control valve to an infusion device. The coupler includes a proximal portion and a distal portion. The proximal portion comprises a plurality of recessed segments configured for receiving the infusion device. The distal portion comprises a valve flange that defines a central cavity for receiving the flow control valve. The valve flange comprises a swage extending radially inward to the central cavity for mechanically engaging a luer lock fitting of the valve assembly.

Some embodiments disclosed herein relate to medical connectors with a housing comprising a proximal body member and a base member that form an internal cavity with a proximal abutment surface. An elastomeric seal without a guide member is positioned within the internal cavity. A rigid, hollow elongated portion is located within the internal cavity such that in an open configuration, a tip of the elongated portion is more proximal than a proximal surface of the elastomeric seal. A distal portion of the elastomeric seal is seated radially within a region surrounded by a plurality of longitudinally extending protrusions.

An airway assist device and methods of making and using an airway assist device to assist in opening an airway or removing fluid or material obstructing an airway of a subject.

A system for treatment of an open wound in a chest of a patient is disclosed. The system includes a seal membrane configured to adhere to the chest and having an air passage. The system also includes a mechanism removably coupled to the seal membrane over the air passage. The mechanism is configured to allow air to pass through the mechanism in a first direction and not to pass in a second direction opposite the first direction.

Modular intravenous (IV) assemblies are provided. The modular IV assembly includes a drip chamber having a body and an inlet connector, a base housing coupled directly to a base portion of the drip chamber, the base housing having an inlet port in fluid connection with the drip chamber and a flow path cavity in fluid connection with the inlet port and a flow control assembly coupled directly to a first portion of the base housing. Any of a filter assembly, an anti-run dry member, a check valve and an air vent assembly may be included in the modular IV assembly. IV sets and methods of use are also provided.

A needleless connector may include a housing having a proximal end, a distal end, and an inner surface defining an internal cavity extending between the proximal and distal ends. A compressible valve may be disposed within the internal cavity. The compressible valve may include a head portion, a flange portion for securing the compressible valve in the housing, and a body portion extending between the head portion and the flange portion. The body portion may include a cylindrical outer surface having an external notch extending along a portion of a circumference of the cylindrical outer surface and recessed radially-inward from the cylindrical outer surface. The body portion may further include a planar face extending distally from the external notch and disposed between the external notch and the flange portion. The planar face may be recessed radially inward relative to at least a portion of the cylindrical outer surface.

Certain embodiments provide multi-medicament or single medicament infusion systems for preventing the cross-channeling or improper delivery of medicaments. The system may include one or more of an infusion pump, medicament cartridges, cartridge connectors, a multi-channel fluid conduit, and an infusion set. The medicament cartridges may be sized and shaped differently such that the medicament reservoirs can only be inserted into the pump under selected configurations.

An automatic pump-based fluid management system, as described herein, comprises an intercostal pump that is, generally, a resiliently flexible bulb having an inlet and an outlet. The inlet is attached to a first tube that extends from the intercostal pump to a first area of a patient's body, for example, the patient's pleural cavity. The outlet is connected to a second tube that extends from the intercostal pump to a second area of a patient's body, for example, the patient's peritoneal cavity. In use, the intercostal pump is placed between a first rib and a second rib in a patient. The intercostal pump operates by being successively compressed and decompressed between the first and second ribs as the patient breaths.
