A waste collection unit is provided that comprises a vacuum pump and smoke evacuation system including a blower and blower motor. The vacuum pump, the blower, and the blower motor, create noise. This noise is attenuated in first and second sound attenuating enclosures for the vacuum pump and the blower and blower motor. A cleaning system is also provided 100 with rotating liquid delivery devices. An actuator is operatively coupled to the liquid delivery devices to rotate the liquid delivery devices.

An oral negative-pressure therapy system includes a container and absorbent insert for the container. The container includes a baffle inside an interior of the container. A fluid passageway extends along the baffle for delivering fluid (e.g., a mixture of air and saliva) into the container. The absorbent insert for absorbing liquid (e.g., saliva) in the container may is over the baffle. At least one of the baffle and the absorbent insert is configured to maintain a fluid flow path between the baffle and the absorbent insert to maintain fluid communication between a fluid inlet and a fluid outlet of the container. The absorbent insert and/or the container may be designed and constructed to burst air bubbles in the aspirated liquid. In one or more embodiments, the absorbent insert is replaceable so that a spent absorbent insert can be replaced with a new, fresh absorbent insert.

A portable apparatus useful for collection and processing of human biological material, such as adipose or cancellous bone material, to prepare a concentrated product (e.g., stromal vascular fraction). The apparatus has a container with a containment volume with a tissue retention volume and a filtrate volume separated by a filter and with a pellet well for collecting concentrate product in the form of a pellet phase from centrifuge processing. The pellet well is accessible only from above when the apparatus is in an access orientation. Collected pellet phase material may be removed from the pellet well by direct aspiration, without suspending the material in a suspension liquid within the container. Access ports may be configured for access only from above the container. The apparatus may include a tissue collector disposed in the disuse retention volume to engage and collect collagen or other stringy tissue. A method of processing adipose tissue to concentrate leuko stromal vascular cells includes multi-step processing using a portable container.

Examples relate to urine collection container baffle structures, and related systems and methods. A urine collection system includes a urine collection device, a conduit, a canister, and a baffle structure. The urine collection device is configured to be positioned at least proximate to a urethra of a user. The conduit is in fluid communication with the urine collection device. The canister has an interior region, and the baffle structure is positioned or positionable in the interior region of the canister.

A bodily fluid collection system includes a reduced pressure treatment unit for providing reduced pressure to a fluid collection system through a canister having a container with an inlet adapted to be fluidly coupled to the fluid collection system, an outlet adapted to be connected to a source of reduced pressure, and an absorptive lamination disposed within the container. The absorptive lamination may be formed from a plurality of absorptive layers and wicking layers interleaved between the absorptive layers that collectively manifold bodily fluids from a tissue site into and throughout the absorptive lamination to trap and collect the bodily fluids. The container expands as the absorptive lamination swells with the bodily fluid being collected.

A method of treating soft tissue conditions. A harvesting device is provided. The harvesting device is operably connected to a tissue processing device using tubing. An aperture is formed in a bone. The bone has an interior. The harvesting device is inserted through the aperture in the bone and into the interior of the bone. The harvesting device is manipulated to dissociate connective tissue progenitor cells in the interior of the bone. Tissue is aspirated from the interior of the bone. The connective tissue progenitor cells are separated from the aspirated tissue. The separated connective tissue progenitor cells are injected in a region of a body that is experiencing a soft tissue condition to treat the soft tissue condition.

A bodily fluid collection system includes a reduced pressure treatment unit for providing reduced pressure to a fluid collection system through a canister having a container with an inlet adapted to be fluidly coupled to the fluid collection system, an outlet adapted to be connected to a source of reduced pressure, and an absorptive lamination disposed within the container. The absorptive lamination may be formed from a plurality of absorptive layers and wicking layers interleaved between the absorptive layers that collectively manifold bodily fluids from a tissue site into and throughout the absorptive lamination to trap and collect the bodily fluids. The container expands as the absorptive lamination swells with the bodily fluid being collected.

The present invention relates to a blood recirculation device. More particularly, the present invention relates to a blood recirculation device capable of continuous blood suction and capable of minimizing mechanical damage to the blood during such a process. The blood recirculation device according to the present invention repeats suction with one side unit and repeats a process of transferring stored blood with the other side unit, thereby being capable of continuous blood suction and capable of efficiently supplying suctioned blood to an erythrocyte washing system of an autologous blood transfusion machine or a cardiopulmonary bypass machine.

Systems, catheters, and methods for accessing and treating along the central nervous system are disclosed. An example method may control operation of a pump of pump/filtration system to facilitate removing cerebrospinal fluid from a patient, filtering the cerebrospinal fluid with a filter module to remove waste product, and returning the filtered cerebrospinal fluid to the patient. Operation of the pump may be adjusted based on a value related to a measure sensed by a sensor in communication with a lumen carrying cerebrospinal fluid through the filtration system.

An apparatus and method for collecting fluid are disclosed. The apparatus includes a body portion comprising a fluid inlet and an outlet, an expandable container secured to the body portion, at least one wicking element extending from within the body portion into the container, and at least one super absorber element arranged inside the container.
