An IV line identification system to enable ready identification of an IV line and its associated fluid source and output from other IV lines with their fluid sources and outputs. The IV line identification system includes an optical member fixed to elongated member that emits light when a light source provides a light into the optical member.

Systems and methods for fluid delivery into a ventilation system are disclosed. In an example, the technology relates to a fluid delivery system for delivery of aerosolized liquid. The fluid delivery system includes an injection tip having a set of orifices configured to aerosolize a liquid having certain properties. The injection tip may be couplable with components of a breathing circuit. For example, the injection tip may be couplable with components at or below a wye component (e.g., at a wye component or between the wye component and a patient), such as at the wye component or at an endotracheal tube multi-port connector. Alternatively, the injection tip may be integrated into a breathing circuit, such as at an endotracheal tube connector or at an endotracheal tube.

A peritoneal dialysis (“PD”) system having an air-aided pumping sequence is disclosed herein. In an example, a PD system includes a housing, a PD fluid pump housed by the housing, an airtrap, a fluid line extending from the airtrap, a fluid line valve positioned and arranged to operate with the fluid line, a gas line extending from an upper portion of the airtrap, and a gas line valve positioned and arranged to operate with the gas line. The system also includes a control unit configured to cause the fluid line valve to close, the gas line valve to open, and the PD fluid pump to pump gas from the airtrap into the gas line after a patient drain to create a pocket of gas in the fluid line and push residual used PD fluid towards a drain line.

Systems and devices for monitoring, detecting, and removing fluid build-up found at various regions along a tracheal tube of an intubated patient. The fluid management system includes pressure and flow sensors for detecting whether there is fluid at the various regions along the tracheal tube, and a means for drawing out the fluid into collection jars. The system also includes lavage features that is able to rinse different the various regions along a tracheal tube. Also disclosed are respiration insertion devices that either couple to existing tracheal tubes or incorporate tracheal tubing, where the respiration insertion body has channels and ports that contact various regions along the tracheal tube. The combination of the fluid management system and the respiration insertion devices effectively monitor and remove fluid at various locations along a tracheal tube of an intubated patient.

Devices for transferring fluid to or from a subject include an extension tube assembly with an axially extending inner tube configured to couple to an elongate tubular cannula having opposing proximal and distal ends with an axially extending lumen and an axially extending inner tube. The inner tube extending through the tubular cannula defines an exposed needle tip and is in fluid communication with the inner tube of the extension tube assembly. The needle tip extends out of a distal end of the tubular cannula a suitable distance.

Filtered bag-valve mask resuscitators are disclosed. Proper ventilation can be delivered to patients with significantly reduced risk of exposing healthcare providers to severe airborne diseases, while not compromising the quality of care and allowing the option of using aerosolized medications. A filtered bag-valve mask resuscitator can also include an angled segment having a lumen configured to deliver gases to and/or from a filter.

A nebulizer assembly for a respiratory device is provided having a housing defining a chamber. The housing also has a nebulizer port configured to receive a nebulizer to discharge atomized medication into the chamber. An outlet of a handle is coupled to the inlet of the housing. A hose is coupled to an inlet of the handle. A patient interface is coupled to the outlet of the housing. Air flows from the hose to the patient interface via the handle and the housing. The air mixes with the atomized medication within the chamber.

Systems and methods for filtering materials from biologic fluids are discussed. Embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject. In an example, CSF is separated into a permeate and retentate using a tangential flow filter. The retentate is filtered again and then returned to the subject with the permeate. During operation of the system, various parameters may be modified, such as flow rate and waste rate.

A composite media includes a stack with 20 or more layers, each layer including a substrate with a first major surface and an opposing second major surface; and a fiber layer deposited onto the first major surface of the substrate and including polymeric fibers with a diameter of 100 nm to 1.5 μm. Each fiber layer independently has a thickness of 5 μm to 100 μm, and each layer independently has a pore size of 0.1 μm to 10 μm. A filter may include a housing and the composite media disposed within the housing. The filter may be a syringe filter.

The disclosure relates to an oven assembly configured for use with a personal electronic vaporizer. Some versions of the oven assembly may include features such as a base, an outer wall extending from the base, a first chamber defined by the outer wall and the base, an oven element disposed in the first chamber, a second chamber defined by the oven element, and at least one opening defined by the oven element. Some versions of oven assembly may be configured to pass heated air therethrough. Some versions of oven assembly may include features such as a heating element disposed in the chamber and configured to be electrically coupled with the vaporizer when the oven assembly is disposed in an oven receiving area of the vaporizer. The heating element may be configured to heat air within the chamber.
