A fluid medical waste canister has interior surfaces that are exposed only to compressive stresses when a vacuum is applied, thereby eliminating the potential for environmental stress cracking. The canister is compatible with medical procedures that generate fluids having high fat/lipid content, such as liposuction procedures. The canister avoids certain stress concentration distributions that cause cracks to close onto themselves, which can cause one or more pieces of the canister wall to rupture into its interior volume. Because the canister is designed to avoid conditions that initiate canister implosion during liposuction procedures, low-cost polystyrene may be used as a waste canister material for such procedures.

Devices and methods herein remove water from human or animal biological waste fluids using one or more forward osmosis filters. The devices allow for the volume of liquid or semi-liquid waste, including potentially infectious liquid waste, to be filtered to reduce potential exposure of healthcare staff to infectious liquid waste. On a hospital, healthcare staff, or individual patient basis, removing water and concentrating the waste can reduce challenges in management and disposal of the waste. Devices herein use forward osmosis to manage and filter, using one or more suitably sized filter(s), biological fluid exudate from wounds. The devices can be constructed to transport water present in the exudate away from a wound. The wound treatment devices herein not only allow for fluid from wounds to be filtered but also provide structures that can protect wounds from external contaminants, including bacteria and viruses. The wound treatment devices can be incorporated into negative pressure wound therapy systems, if desired.

Systems, devices and methods for draining and analyzing bodily fluids are disclosed in which a drainage assembly is configured to prevent negative pressure build-up. The drainage assembly generally includes a catheter which may include a drainage lumen, a reservoir, a venting mechanism in fluid communication with the drainage lumen and a positive pressure lumen, and a controller. The venting mechanism may further include a valve which is configured to maintain a closed position, as well as a vent in fluid communication with the valve, where the venting mechanism is configured to inhibit wetting of the vent from fluid within the drainage lumen

Preparation of a product comprising stromal vascular traction cells includes washing human biological material comprising adipose in a container apparatus having an internal filter, which divides an internal containment volume of the container apparatus into a tissue retention volume on one side of the filter and a filtrate volume on an opposite side of the filter, and a mixing device with at least one rotatable mixing member disposed in the tissue retention volume. The washing includes operation of the mixing device to rotate the mixing member through the human biological material within the tissue retention volume, and the washing is followed by digesting washed material within the internal containment volume with added enzyme, centrifuging of the container apparatus to prepare a centrifuged pellet in the filtrate volume, selectively removing material of the pellet and preparing a product with a mixture of stromal vascular fraction cells of removed pellet material and an aqueous suspension liquid.

A self-placeable external catheter is disclosed that includes a catheter body having at least a top side and a bottom, a wicking area disposed on the top side, a finger covering extending from the bottom side of the catheter body creating a cavity configured to receive a user finger, and an aperture formed in the bottom side of the catheter, wherein the wicking area receives urine such that the urine passes through the wicking area, through the catheter body and through the aperture. The catheter tubing may be inserted into the aperture such that the urine passes through the wicking area, through the catheter body and through the aperture into the catheter tubing. An opening of the cavity may face a proximal side of the catheter body and the wicking area may include gauze.

System and methods for analyzing the contents of a fluid canister are provided for use in healthcare settings. The system includes optical and weight sensors to analyze the canister contents.

A wound treatment appliance is provided for treating all or a portion of a wound. In some embodiments, the appliance comprises an impermeable flexible overlay that covers all or a portion of the wound for purposes of applying a reduced pressure to the covered portion of the wound. In other embodiments, the impermeable flexible overlay comprises suction assistance means, such as channels, which assist in the application of reduced pressure to the area of the wound and removal of exudate from the wound. In other embodiments, the wound treatment appliance also includes a vacuum system to supply reduced pressure to the wound in the area under the flexible overlay. In yet other embodiments, the wound treatment appliance also includes wound packing means to prevent overgrowth of the wound or to encourage growth of the wound tissue into an absorbable matrix comprising the wound packing means. In still other embodiments, the appliance may include a suction drain. In other embodiments, the appliance may include a collection chamber to collect and store exudate from the wound. In yet other embodiments, a suction bulb may be used to provide a source of reduced pressure to an impermeable overlay that covers all or a portion of the wound. Finally, methods are provided for using various embodiments of the wound treatment appliance.

A portable drain system having a subdermal drain and a container in fluid communication with the subdermal drain is disclosed. The subdermal drain is configured to drain fluid from a surgical site. The container provides a negative pressure to the subdermal drain. The container draws and receives the fluid. The container includes at least one sensor in which the at least one sensor is configured to detect at least one of fluid color, fluid volume in the container, and orientation of the container.

A waste collection cart assembly for collecting waste material from a suction line during a medical procedure. The waste collection cart assembly includes a housing having a top portion defining a work surface. A waste container is coupled to the housing for collecting the waste material from the suction line. A manifold receiver defining an opening is coupled to the waste container. A manifold having a specimen trap is received within the opening of the manifold receiver. A vacuum source is coupled to the waste container. The vacuum source provides a vacuum on the waste container to draw the waste material from the suction line through the manifold and into the waste container. The specimen trap collects a specimen from the waste material while being drawn into the waste container. The specimen may be transferred to a specimen container disposed on the work surface.
