A blood filtration system can reduce the amount of plasma constituents (e.g., water and/or electrolytes) in the blood of the patient, and accordingly increase the hematocrit value of the patient. The blood filtration system (e.g., a controller, or the like) can determine a hematocrit value of a patient. The blood filtration system can determine a venous pressure of vasculature of a patient. The blood filtration system can compensate for pressure head in a component of a blood circuit (e.g., a withdrawal line of a catheter), for example to improve the accuracy of the venous pressure determination. The blood filtration system can determine one or more resistance characteristics of a blood circuit for the blood filtration system. The resistance characteristics can correspond to a resistance to a flow of blood through a component of the blood circuit.

The invention provides intravascular devices for treating certain medical conditions such as edema without causing thrombosis. The intravascular devices of the disclosure include non-thrombogenic surfaces that improve blood compatibility by reducing device-related thrombus formation and inflammatory reactions. The non-thrombogenic surfaces may include surface topographies (e.g., surface roughness) and modified chemistries (e.g., coatings and/or treatments), which prevent thrombosis by reducing local shear forces and inhibiting adhesion of blood clotting factors.

A mask apparatus for a respiratory treatment can permit delivery of breathable gas to a user. In one example, the mask may employ a frame and cushion to form a seal for both mouth and nose. The frame may be adapted for coupling with a respiratory treatment apparatus so as to permit communication of a pressurized gas from the respiratory treatment apparatus. The cushion, which may be foam, may have a substantially under the nose configuration or over the nose configuration. The mask may have a common plenum chamber for both nose and mouth. The cushion may further define a centrally open lip superior region. The cushion may be adapted to couple with the frame directly or to the frame in conjunction with a cushion support clip. Various features of the cushion may further promote sealing and comfort for the under the nose design.

A protective cover or sleeve for a medical spike product is provided. The protective cover includes a first panel having a lower edge, and a second panel having a lower edge, wherein the first panel and the second panel are connected at their lower edges, respectively. The first panel and the second panel are configured to be spaced apart to form a protective sleeve. The protective sleeve is configured to receive the medical spike product such that the first panel and the second panel protectively cover and enable aseptic handling of a spike end of the medical spike product and prevent the spike end from breaching a sterile barrier. The protective sleeve may be made from a paper-based material. A medical spike product assembly including the protective cover and a medical spike product inserted therein is also provided.

An air venting device may include an adapter comprising a tubular body having a hollow interior defining a fluid flow path, and a vent plug detachably coupled to at least a portion of the tubular body. The vent plug may include an inner circumferential surface defining an internal chamber of the vent plug, and the fluid flow path of the adapter may fluidly communicate the adapter with the internal chamber of the vent plug. The vent plug may further include a superabsorbent polymer material disposed in the internal chamber. The superabsorbent polymer material may be configured to (i) absorb a liquid entering the internal chamber from the fluid flow path, and (ii) expand in volume as the liquid is absorbed into the superabsorbent polymer material. Air entrained in the liquid entering the internal chamber may be vented to an exterior of the air venting device via the vent plug.

A solid medication insertion device includes a barrel having an insertion end portion and a proximal end portion opposite the insertion end portion and having a continuous side wall extending therebetween that defines an interior area. A medicament is initially positioned in the interior area of the barrel. The medication insertion device includes a plunger slidably coupled to the barrel that has a first end engaging a proximal end of the medicament, the plunger having a cylindrical configuration selectively slidable from a starter configuration extending away from the proximal end portion of the barrel to a deployed configuration positioned downstream inside the interior area of the barrel. Pressure applied to the plunger causes the plunger to urge the medicament downstream within the interior area of the barrel. The medication insertion device, i.e., the suppository applicator, is constructed using a material consisting essentially of hemp plastic.

Lightweight, portable oxygen concentrators that operate using an ultra rapid, sub one second, adsorption cycle based on advanced molecular sieve materials are disclosed. The amount of sieve material utilized is a fraction of that used in conventional portable devices. This dramatically reduces the volume, weight, and cost of the device. Innovations in valve configuration, moisture control, case and battery design, and replaceable sieve module are described. Patients with breathing disorders and others requiring medical oxygen are provided with a long lasting, low cost alternative to existing portable oxygen supply devices.

Nasal respiratory assembly includes a pair of sheets. Each sheet defines an opening sized and shaped to fit over a nostril of a patient, with a ferromagnetic dome-shaped ring positioned at an underside of the sheet, with an upper side of the sheet configured for sealable engagement with the nostril. The assembly also includes a pair of posts. Each post includes a magnetic ring positioned at a first end and a ball shaped receptacle positioned at a second end. The magnetic ring is removably attachable to the dome-shaped ring. The assembly further includes a pair of conduit adapters with openings therethrough for fluid flow. A post end of each conduit adapter includes a socket, each socket shaped to receive the ball shaped receptacle in a ball and socket arrangement to form a substantially airtight connection therewith.

A sanitary extubation cover used to cover an endotracheal tube and a patient's face in order to accommodate sanitary extubation. The sanitary extubation cover includes a mask and a cover which covers the endotracheal tube. If the patient coughs, the cough would be directed into the mask and the endotracheal tube (which is covered by the cover) but contaminants from the cough would be suppressed from spreading into the open air. The mask can have an air cushion at the bottom of the mask in order to securely press against the patient's face. The mask can also have a solid silicone base at the bottom of the mask in order to securely press against the patient's face.
