A filter for medical infusion lines includes a box-like body having an inlet connector and inside which there is arranged a plate-like element on whose one or both opposite faces there are formed respective channels placed in communication with an outlet connector. Filtering hydrophilic membranes separate the channels from at least one interspace placed in communication with the inlet connector. With the outlet connector there is operatively associated an overpressure valve incorporated in the box-like body of the filter.

Disclosed is a blood oxygenator. The blood oxygenator includes a blood inlet chamber, and a housing.

Multiple hollow fibrous membrane fibers are arranged in the gas exchange zone. The blood inlet chamber includes an inverted conical side wall and an end surface hermetically connected to an opening at one end of the inverted conical side wall, an opening at the other end of the inverted conical side wall is hermetically connected to one end of the housing, and the other end of the housing is hermetically connected with a cover body. The cover body is provided with a blood outlet, and the end surface is provided with a spiral liquid inlet pipe coaxial with the blood inlet chamber.

The invention relates to a filter element which is configured in the form of a pocket or a tube with an inner space extending in a longitudinal direction and has a multilayer structure which has a permeable outer layer, a permeable inner layer and at least one intermediate layer arranged between the outer layer and the inner layer, which is configured as a fine-pored filter element, wherein the filter element has a predetermined axial length, and wherein the outer layer and the inner layer have the predetermined axial length. It is according to the invention that the intermediate layer is formed axially shorter than the outer layer and the inner layer to form an overflow region disposed at an axial upper end portion of the filter element, wherein an upper edge of the intermediate layer is spaced axially downward from the upper edge of the outer layer and the inner layer, that the outer layer, the inner layer and the intermediate layer are firmly connected to one another along at least one longitudinal edge to form a longitudinal connecting seam, and that the outer layer and the inner layer are firmly connected to one another along their upper edge to form an upper transverse connecting seam, wherein the upper edge of the intermediate layer is arranged free and unconnected between the outer layer and the inner layer.

A canister for use with a wound therapy system includes first and second compartments configured to receive and contain wound exudate, and an airflow pathway. The airflow pathway includes a planar region positioned between the first compartment and the second compartment, an inlet extending from a first end of the planar region at an obtuse angle relative to the planar region, an outlet at a second end of the planar region.

Dialysis is enhanced by using nanoclay sorbents to better absorb body wastes in a flow-through system. The nanoclay sorbents, using montmorillonite, bentonite, and other clays, absorb significantly more ammonium, phosphate, and creatinine, and the like, than conventional sorbents. The montmorillonite, the bentonite, and the other clays may be used in wearable systems, in which a dialysis fluid is circulated through a filter with the nanoclay sorbents. Waste products are absorbed by the montmorillonite, the bentonite, and the other clays and the dialysis fluid is recycled to a patient's peritoneum. Using an ion-exchange capability of the montmorillonite, the bentonite, and the other clays, waste ions in the dialysis fluid are replaced with desirable ions, such as calcium, magnesium, and bicarbonate. The nanoclay sorbents are also useful for refreshing a dialysis fluid used in hemodialysis and thus reducing a quantity of the dialysis fluid needed for the hemodialysis.

A surgical fluid management system delivers fluid for distending a uterine cavity to allow cutting and extraction of uterine fibroid tissue, polyps and other abnormal uterine tissue. The system comprises a fluid source, fluid deliver lines, one or more pumps, and a filter for re-circulating the distension fluid between the source and the uterine cavity. A controller can monitor fluid retention by the patient.

A device for rapid detection of a tuberculosis lipoarabinomannan (TB-LAM) is provided. The device includes a pre-concentrator unit for concentrating the TB-LAM comprising: an ion-exchange medium comprising one or more ligands configured to capture the TB-LAM from the source biological sample, wherein the captured-TB-LAM is eluted from the ion-exchange medium as an eluate comprising a concentrated form of TB-LAM; a cassette; a lateral flow assay unit disposed in the cassette; and an integration unit attached to the pre-concentrator unit and the cassette. The integration unit is configured to operatively couple and de-couple the pre-concentrator unit and the cassette. The pre-concentrator unit and the lateral flow assay unit disposed in the cassette are in a fluidic communication in a coupled form. The device for rapid detection of TB-LAM further comprises a dilutor unit.

Provided, among other things, is a method of treating cerebral spinal fluid comprising: (a) utilizing a channel of a pump to draw CSF from a subject's subarachnoid space of the subject's brain or spinal column; (b) subjecting the drawn CSF to membrane dialysis against a dialysate fluid to reduce immune or inflammatory mediators; and (c) utilizing a second channel of the synchronized dual channel pump to return the dialyzed CSF to the subarachnoid space of the subject's brain or spinal column. For example, the pump can be a synchronized dual channel pump. In one embodiment, the method further comprises: (d) removing cellular matter from the CSF to produce reduced cell content CSF, wherein the reduced cell content CSF is subjected to membrane dialysis.
