A connector arrangement (10) for connecting to a fluid chamber (6) of a blood treatment unit (4) for extracorporeal blood treatments. The connector arrangement (10) includes a connector device (11) with a connector body (47) comprising a port opening (43) and an interior wall (50) defining a port space (39) designed to receive a first fluid port (8A) of the fluid chamber (6). The connector device (11) also incorporates a fluid path (35a) extending from the port space (39) to a first end opening (51) of the connector device (11), and an air path (36a) extending from the port space (39) to a second end opening (52) of the connector device (11), wherein the fluid path (35a) and the air path (36a) are separate paths. Also a system (1) for extracorporeal blood treatment including the connector arrangement (10) and a method for priming the fluid chamber (6).

The present disclosure provides devices and methods for processing and harvesting adipose tissue. The present disclosure provides improved devices, systems, and methods for harvesting, processing, and filtering adipose tissue for autologous fat transfer procedures. The features of the devices and systems of the present disclosure increase efficiency and sterility of adipose tissue processing by reducing the need for users to interrupt the procedure to adjust some part of the system, such as unclogging filter pores or adjusting tubing.

A fluid delivery Y-site is described that is configured to receive and control delivery of two or more fluid flows. Fluid flow is controlled within a chamber by a valve and float. Flow of a primary fluid into the chamber is reduced or halted by the movement of a valve. The valve may occlude a first flow port into the chamber in response fluid flowing from a second flow port into the chamber. A float is moveably disposed within the chamber and configured to engage the valve in response a fluid flow into the chamber from the second flow port. As fluid flow from the second flow port into the chamber is reduced or ceases, the valve and float allow the flow from the primary flow port to once again enter the chamber and exit from an outlet port.

A negative pressure wound therapy apparatus can include a wound dressing, a fluid collection container, a vacuum pump comprising a pump motor, and tubing. Additionally, the apparatus can include a pressure sensor that measures a pressure in the tubing. One or more tubes can channel a fluid between the wound dressing, the fluid collection canister, and the pump. In addition, first and second control circuits can be provided for controlling the pump motor without using a processor. The first control circuit can generate a difference signal between a desired pressure input and a pressure sensor input, and can further generate a motor control signal responsive to the difference signal. Moreover, a second control circuit can provide an override signal based at least in part on the difference signal and at least one reference signal. The override signal beneficially overrides the motor control signal to prevent the pump motor from stalling.

A surgical waste collection unit with a receiver for removably holding a manifold to which suction lines are connected. The receiver is mounted to the waste collection unit to be at an acute angle relative to the horizontal. The receiver is further configured to allow the manifold to be rotated in the receiver. This means the manifold can be rotated from a first position in which the manifold outlet opening is aligned with the conduit through which waste is flowed from the receiver and a second position in which the manifold outlet opening is elevated relative to the first position.

A canister lid (100) for a canister (600) includes an annular perimeter (101) surrounding an interior portion (102). Rather than completely surrounding the interior portion, the annular perimeter is instead interrupted by a suction conduit (103) defined by a suction duct (104) separating a first lobe (105) and a second lobe (106). The suction duct (104) intersects the annular perimeter such that the first lobe is disposed interior of the annular perimeter while the second lobe is disposed exterior to the annular perimeter. The canister lid can further include one or more ports (110,111) extending from the interior portion.

A portable vacuum device including: a source of liquefied gas; a gas operated vacuum generator having a vacuum inlet; a valve for controlling flow of gas from the source to the vacuum generator; a suction tube having proximal and distal ends; a collection container having an outlet coupled to the vacuum inlet of the vacuum generator and an inlet coupled to the proximal end of the suction tube, the arrangement being such that when said valve is opened the vacuum generator creates a vacuum in the container and at the distal end of the suction tube.

Moreover, a second control circuit can provide an override signal based at least in part on the difference signal and at least one reference signal. The override signal beneficially overrides the motor control signal to prevent the pump motor from stalling.

Disclosed are lactation assistive devices. The lactation assistive device may include a stimulation component and a controller. The stimulation component may include electrical components or mechanical components to stimulate a breast. The stimulation component may be sized to fit within a garment worn about the breast and may define an opening to be located proximate a nipple of the breast when the garment is worn. The controller may be configured to control stimulation of the breast by the stimulation component.

Various implementations of a fluid collection system having a flexible liner are disclosed. In one exemplary variation, the fluid collection system may include a container having a top opening, a lid configured to close the top opening, and a flexible liner attached to the lid. The liner may be interposed between the lid and the container when the lid closes the top opening. The liner and the lid may define a substantially sealed interior space therebetween. The lid may include an access port through which the interior space receives fluid. The flexible liner may also be configured to controllably collapse as the fluid is removed from the interior space.
