Systems and methods for improving airway patency are disclosed. An oral device is positioned in the oral cavity and applies a negative pressure to the oral cavity. The oral device has pressure delivery ports directed toward an anterior surface of the soft palate when positioned therein. The negative pressure generates an air flow out of the oral cavity. A pressure tube is coupled to the oral device to provide the applied negative pressure. A pressure source is coupled to the pressure tube to generate the applied negative pressure. A collector is coupled to the pressure tube and/or pressure source to collect liquid, typically saliva, from the air flow out of the oral cavity. The collector is disposed outside of the oral cavity and coupled to the oral device.

The present disclosure provides devices and methods for harvesting and processing tissue from patients for grafting. The devices can include a tissue collection chamber for ascetically collecting, processing, and/or re-implanting adipose tissue.

A removable manifold for a medical/surgical waste collection system. The manifold is dimensioned to be mounted to a receiver integral with the system. The manifold includes at least one tube through which waste is drawn into a manifold cage. The tube extends through an inlet port into a void space internal to the manifold cage at an angle. The tube exits the manifold cage and centered along an axis that is off center to the longitudinal axis of the manifold cage where it engages a complementary valve internal to the receiver. The valve regulates flow between the receiver and the down line components of the waste collection system. The valve is normally closed. When the manifold is fitted to the receiver the tube engages the valve and rotation of the manifold moves the valve to the open position allowing fluid flow from the manifold and receiver to the downstream components of the system.

A device for aspirating and transferring blood during a surgical operation has a first chamber and a second chamber for collecting and transferring the aspirated blood, and an electronically controlled valve unit for connecting the chambers to a vacuum source. The valve unit establishes this connection alternately between the first chamber and the vacuum source and the second chamber and the vacuum source, such that the first or second chamber connected to the vacuum source can be filled with aspirated blood, and the other, second or first chamber can be emptied at the same time. The valve unit is connected to the first and second chamber and permits a pressure increase in the first or second chamber to be emptied. This device allows blood to be efficiently collected and transferred during operations in a way that is gentle on the blood.

A snivel suction apparatus includes a suction mechanism and an air extraction mechanism. The air extraction mechanism is connected to the suction mechanism. The air extraction mechanism includes a pump, a piston, a communicating tube, a first check valve and a second check valve. The piston is arranged on the pump. One side of the communicating tube is connected to the pump. The other side of the communicating tube is connected to the suction mechanism. The first check valve is arranged in the pump and at one side of the communicating tube. The second check valve is arranged on the pump.

The present disclosure provides devices and methods for harvesting and processing tissue from patients for grafting. The devices can include a tissue collection chamber for ascetically collecting, processing, and/or re-implanting adipose tissue.

A tissue collection and processing system for collecting bone fragments and tissue aspirated from a bone. The tissue collection and processing system includes a collection vessel, a collection vessel cap, a processing piston, a first tubing and a fluid withdrawal mechanism. The collection vessel has an opening formed therein to receive bone fragments and tissue aspirated from the bone. The collection vessel cap is capable of engaging the collection vessel to substantially seal the opening. The collection vessel cap or the collection vessel has a first port. The processing piston has an upper surface and a lower surface. The processing piston has a connection port and a bore. The connection port is proximate the upper surface. The bore is fluidly connected to the connection port and extends toward the lower surface. The processing piston has a density that is less than a density of fluid in the aspirated bone fragments and tissue. The fluid withdrawal mechanism is fluidly connected to the connection port with the first tubing to withdraw the fluid from the collection vessel. As fluid is withdrawn from the collection vessel, the processing piston is slidable in the collection vessel.

An aspiration and irrigation ultraportable device is disclosed. The device is configured to aspirate and irrigate alone or sequentially. The device comprises a digitally adjustable dry/wet vacuum and a spray/irrigator assembly that is powered by rechargeable batteries. The device has at least one easily disposable and cleanable aspirant/irrigant reservoir. The present invention relates to the field of medicine specially related to outpatient and in-home settings of aspiration and irrigation of nose, ear, open wounds, and other body fluids.

Lipoaspirate can be treated for use in fat grafting procedures. For example, the lipoaspirate can be placed in a container having an inlet for receiving the lipoaspirate and an outlet for dispensing and removal of desired materials from the lipoaspirate. The inlet and the outlet can be located on a common side of first and second filter elements. An activation mechanism can be actuated to move the first filter element relative to the second filter element within the container to separate cellular components of the lipoaspirate from non-cellular components of the lipoaspirate.

A medical waste fluid collection cart may include a container assembly and a suction tube having a lumen extending through the suction tube. The suction tube may communicate with the container to deposit waste fluid from a surgical site in the container. The container assembly may include a container, a base forming a bottom of the container, and a lid assembly. The base may include an interior surface defining a draining opening. The interior surface may extend along a ramped path toward the drain opening. The lid assembly may include a lid ring and a lid capable of engaging each other with a twist lock mechanism. The lid ring may engage the container and the lid may cover at least part of a central opening to the container. The container may have a window and a tinting assembly. The container assembly may have a vacuum level detection system.
