A device for preventing contamination of a positive-pressure connector (6) of an indwelling needle and a method based on same. The device comprises a shell (1), a connecting port (3) fixedly connected to the shell (1) and used for connecting to the positive-pressure connector (6), an air pressure balance hole (5) disposed opposite to the connecting port (3) and provided on the shell (1), and a filtering membrane (2) provided between the air pressure balance hole (5) and the connecting port (3). The device is simple in structure, adopts a structural design of the filtering membrane (2), can filter microorganisms, bacteria, viruses, dusts, and particulate pollution sources, and is used during indwelling of infusion intervals to prevent the positive-pressure connector (6) from being exposed to the air and maintain the aseptic state and positive-pressure condition of the positive-pressure connector (6) during indwelling.

Aspects of the invention include devices, systems, and methods for enhancing a user's sleep. A flexible frame supports a flow manifold which can be used in unison with adjoined or adjacently integrated supportive members utilized to create soft objects of various designs and materials. These types of objects can be in the form of a pillow, mattress topper, even a child's stuff animal and other various stationary and portable soft sided padded embodiments as disclosed in this application. These various designs and embodiments house an integrated flow delivery system which is delivers concentrated, pressurized, and or altered gaseous flowing elements in a controlled and fluidic manner as to help address certain types of sleeping and breathing issues during their resting and sleep states.

A tray and a manifold for collecting a tissue sample under influence of a vacuum. The manifold includes a sleeve, and the tray includes a sealing member configured to be removably positioned in sealing engagement with the opening. A basket defining a tissue collecting cavity, and a base portion includes at least one rib disposed within said tissue collecting cavity. The rib(s) define pockets arranged in series in the proximal-to-distal direction so as to provide low pressure regions when the tray is being removed from the sleeve. The rib(s) may be transverse to a longitudinal axis, and/or arcuate in a shape complimentary to the base portion. The base portion defines porous features that may be arranged in groupings A sealing edge in sealing engagement with an upper barrier of the sleeve may delay an onset of airflow entering the tissue collecting cavity.

A manifold configured to be inserted into a receiver of a medical waste collection system for filtering medical waste, including fluid, received under the influence of a vacuum provided by the medical waste collection system. The manifold includes a housing defining a manifold volume and an outlet opening near an upper aspect of the housing. The manifold further includes a filter element and a baffle wall disposed within the manifold volume. The baffle wall is arranged to define a sump region of the manifold volume, which is positioned below a lowermost aspect of the outlet opening such that fluid in the suction path is pulled from below the outlet opening, thereby reducing a level of fluid retained within the manifold when the manifold is removed from the receiver.

A cover layer for a vacuum wound therapy dressing includes a backing layer formed from a flexible polymeric membrane and an adhesive layer for affixing the backing layer over a wound bed to provide a substantially fluid-tight seal around a perimeter of the wound bed. The cover layer is reinforced with a reinforcement layer extending to a peripheral region of the backing layer to distribute forces associated with evacuating a reservoir, as defined by or within the cover, to stimulate healing of the wound bed.

A method and system for processing an adipose tissue material sample to create and collect fat aspirate particles having particle diameters less than or equal to a selected size are disclosed. A filter screen assembly having an interface part, a closed end opposite to the interface part, and a screen portion therebetween is inserted through a first port in a lid of a container, with the interface part providing access to an interior of the container for insertion of a transfer cannula connected to a syringe filled with the adipose tissue material. The screen portion includes a plurality of apertures having diameters of the selected size. Adipose tissue material is expelled from the transfer cannula through the apertures of the filter screen assembly into the container to create and collect the fat aspirate particles having particle diameters less than or equal to the selected size.

Presented herein are methods, systems, and apparatus for administering an antibody treatment via an infusion device, e.g., a rapid infusion device, e.g., for the treatment of a disease or condition that requires one or more infusions of monoclonal and/or polyclonal antibodies.

A medical fluid treatment system includes a source of purified water; at least one concentrate for mixing with the water from the source to form a treatment fluid; a disposable set including a pumping portion, a concentrate line in fluid communication with the concentrate source and the pumping portion, and a patient line in fluid communication with the pumping portion, the patient line including a filter having a membrane configured to filter the treatment fluid, the filter configured such that (i) fresh treatment fluid flowing from the pumping portion towards a patient flows through the membrane and (ii) used treatment fluid flowing through the filter from the patient to the pumping portion bypasses the membrane; and a medical fluid delivery machine including a pump actuator operable with the pumping portion of the disposable set.

The subject matter described herein includes a kidney stone suction tube device and related methods of use. According to one example, the disclosed subject matter includes a suction tube device comprising a flexible tubing element comprising a modified suction tube portion characterized as having U-shaped hollow lumen channel and an intra-renal portion characterized as having circular shaped lumen channel. The intra-renal portion of the suction tube device further includes a collection cylinder section configured for storing kidney stone fragments. In addition, the connection of the modified suction tube portion and the collection cylinder section includes a mesh filter element configured to prevent admittance of kidney stones into the modified suction tube portion of the flexible tubing element.
