Vacuum dressings with a guide tube are provided for implantable medical devices that inhibit infection associated with in-dwelling devices while encouraging healing of the incision around the device. The vacuum dressings mitigate pooling of fluids that harbor bacteria from between the outer diameter of an inserted implantable medical device and the inner diameter of a guide tube and also in the cylindrical gap, between the outer diameter of an inserted implantable medical device and the inner wall of the subcutaneous tunnel, which remains in fluid communication with skin microflora. Implantable medical devices may also illustratively include a variety of catheters, such as venous access, peritoneal dialysis, and other indwelling venous access catheters that require skin penetration; cannulas; Steinman pins; Kirschner wires; and cardiac assist device lines.

A portable suction pump for aspirating secretions from a patient's artificial airway includes a peristaltic pump head, a suction tube extending from a patient through the peristaltic pump head, the suction tube having a tee-fitting conduit, and a collection container having a plurality of ports for collecting patient media. A clinician has an ability to increase or decrease vacuum levels without increasing or decreasing flowrate and/or an ability to increase or decrease the flow rate without increasing or decreasing the vacuum levels. The tee-fitting conduit extends to a vacuum sensor port connecting to a vacuum sensor in communication with a processor, the processor controlling a proportional valve employed to regulate the vacuum levels.

Disclosed herein are several embodiments of a negative pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed towards wound dressings comprising a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, the absorbent layer overlying the transmission layer, a gas impermeable cover layer overlying the absorbent layer and comprising a first orifice, wherein the cover layer is moisture vapor permeable. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.

Embodiments include a vacuum assisted venous drainage (VAVD) system, including a regulator valve assembly configured to facilitate application of vacuum to a reservoir; a control unit configured to control the regulator valve assembly to facilitate controlling application of the vacuum; at least one pressure sensor coupled to the reservoir and configured to obtain pressure measurements of pressure in the reservoir; a heating element configured to heat the regulator valve assembly to a target temperature; and at least one temperature sensor configured to determine a temperature of the regulator valve assembly.

In some embodiments, a housing can define a reservoir. A lower cap can be coupled to the housing and define an outlet, and an upper cap can be coupled to the housing and can define an inlet. The upper cap can include an extending portion extending laterally a distance beyond an outermost extending portion of the lower cap relative to a central axis of the housing such that, when the lower cap and the extending portion of the upper cap contact a horizontal surface, the central axis of the housing is transverse to the surface and a sealing member is configured to sealingly engage a sealing surface of a valve seat prior to a liquid fluid level within a reservoir decreasing below a minimum threshold fluid level.

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 breast pump device (1) comprises an expression kit (2), a vacuum unit (3), and a conduit (5) for establishing an air path between an air outlet (27) of the expression kit (2) and an air inlet (35) of the vacuum unit (3). The expression kit (2) is equipped with a barrier portion (26) for preventing milk leakage from the expression kit (2) towards the hose (5) and the vacuum unit (3). In case some droplets of milk enter the barrier portion (26) and/or drawn through the barrier portion (26) by an ongoing pumping action, aspects of the behavior of the motor (32) for driving the pump (31) are influenced, and the insight that this happens is used for terminating operation of the motor (32) as soon as a too large deviation of one or more operational characteristics of the motor (32) with respect to a reference is found.

The invention relates to the providing of hydrophobic and hydrophilic polymer-based hollow fiber membranes containing a water-insoluble antioxidant; in particular, the invention relates to the providing of hollow fiber membranes for the extracorporeal treatment of blood, wherein the hollow fiber membranes have improved biocompatibility relative to treatment blood, in particular improved complement activation and lower platelet loss vis-à-vis treatment blood. At the same time, the elution of hydrophilic polymers from the lumen of the hollow fiber membrane is reduced.

Disclosed embodiments relate to wound therapy apparatuses and methods for use in negative pressure wound therapy (NPWT). Such wound therapy apparatuses and methods may reduce maceration during NPWT. The wound therapy apparatus may include a porous hydrophobic layer surrounded by a hydrophilic ring. The hydrophilic ring may serve to prevent passage of liquid while negative pressure is applied to the wound, but allow liquid passage to an absorbent ring when negative pressure is no longer applied. A transmission layer may also be included, underlying the absorbent layer.

A medical device system. The system includes a first medical device, a first remote interface, and a second remote interface in communication with the first remote interface and the first medical device, wherein the first medical device sends a command to the first medical device through the second remote interface, and wherein when the second remote interface receives the command, the command must be confirmed by the second remote interface before the command is send by the second remote interface to the first medical device.
