Systems and methods for effecting bariatric procedures are disclosed. Each system includes an instrument, a control valve and, optionally, a suction controller. The instrument is in the form of an elongated, flexible member having a distal end portion arranged for anchoring the instrument in the patient's stomach and for enabling fluids to be removed from the patient's stomach. Suction is applied to the patient's stomach by the distal end portion of the instrument to drain gastric fluids and to bring adjacent portions of the patient's stomach into engagement with the instrument to provide a visually perceptible delineation line along which a portion of the stomach may be resected, sealed and tested.

A disposable uterine endoscope relates to the technical field of medical instruments. The disposable uterine endoscope includes a handle mechanism and an intubation mechanism. The intubation mechanism includes a rotary inner tube and a supporting outer tube. One end of the rotary inner tube is rotatably connected with the handle mechanism and the other end of the rotary inner tube is connected with a camera. The supporting outer tube is sleeved in a circumferential direction of the rotary inner tube, one end of the supporting outer tube is fixedly connected with the handle mechanism and the other end of the supporting outer tube is provided with a bent section, the bent section is provided with a continuous bent groove, and the bent groove is arranged spirally along the circumferential direction of the bent section.

A dressing for treating tissue with negative pressure is provided herein comprising a composite of dressing layers, including a release film, a perforated coated polymer film, a manifold, and an adhesive cover. Additionally, a method of manufacturing the dressing may comprise applying a cross-linkable polymer to a polymer film, curing the cross-linkable polymer to a gel layer to form a coated polymer film, and perforating the coated polymer film to form fluid restrictions, such as slits and/or slots, though the coated polymer film.

Microbubbles detached from a blood circuit and a blood purification unit are discharged with the use of a backflow generated at the instant that a roller of a blood pump releases a squeezable tube. In a normal rotation step, a region filled with a priming solution after a priming step is closed by a closing unit, and a rotor of a blood pump is rotated normally until a roller of the blood pump releases a squeezable tube to generate a backflow. After the backflow is generated at the release of the squeezable tube by the roller of the blood pump, bubbles are moved by reversely rotating the rotor while disabling the closing by the closing unit. Thus, the bubbles are discharged through a discharge unit.

An appliance is provided for negative-pressure therapy of wounds on the human or animal body in which, on the one hand, a substance is delivered to a wound bed (W) and, on the other hand, fluids, in particular an exudate and the delivered substance, are aspirated from the wound bed by negative pressure. The appliance has a suction pump housing, with a suction pump arranged therein for aspirating the fluids from the wound bed (W), and a fluid collection container for collecting the aspirated fluids. Moreover, the appliance has a first measuring device and a second measuring device. The first measuring device serves to determine the quantity of the aspirated fluids, and the second measuring device serves to determine the quantity of the substance delivered to the body.

A vacuum sponge system, comprising: a sponge having an outer surface, a proximal end and a distal end, spaced from the proximal end in an axial direction of the sponge; a drainage tube disposed partially in the sponge, and is in fluid communication with the sponge; the drainage tube is connectable with a vacuum pump such that a pressure is applicable to the outer surface of the sponge; and a delivery member having an outer surface and extending in an axial direction of the sponge and adapted to establish a fluid communication between a region from the distal end of the sponge and region from the proximal end of the sponge. The pressure provided by the pump via the drainage tube is applied to a vicinity of the outer surface of the delivery member and the outer surface of the sponge. The delivery member is disposed partially radially outside of the sponge.

A rectal drainage appliance is disclosed comprising a tubular element having an inflatable balloon at a distal end for anchoring the appliance in the rectum. The appliance includes one or more of: (i) first and second auxiliary lumens communicating with the inflatable balloon to provide independent inflation and pressure monitoring paths coupled to the balloon; (ii) a pressure state indicator defined by a mechanical element configured to flip between first and second states or shapes responsive to sensed pressure; and (iii) a collapsible auxiliary lumen larger than the inflation lumen, and configured to permit admission of irrigation fluid. The pressure state indicator may also be used in intestinal drains.

A porous conduit may be suitable for use in treating a tissue site, and may include a central lumen and a porous wall positioned substantially concentric about the central lumen. The porous wall may have an open porous structure that may define a plurality of interconnected pores in fluid communication with one another. As part of a system, the porous conduit may be used with a manifold adapted to be positioned at a tissue site, a sealing drape adapted to cover the manifold to provide a sealed space relative to the tissue site, and a therapy device including a reduced-pressure source. The porous conduit may be disposed in the sealed space and in fluid communication between the sealed space and the reduced-pressure source.

A device for irrigation of an oral cavity in a patient includes a suction element configured to be disposed in the oral cavity and configured to suction a fluid out of the oral cavity. The suction element also has one or more irrigation outlets configured to irrigate the oral cavity with the fluid. A suction line is fluidly coupled with the suction element and is configured to be fluidly coupled with a vacuum source. An irrigation line is fluidly coupled with the one or more irrigation outlets and is fluidly coupled with a source of the fluid.

The wound dressing apparatus facilitates administration of combined negative pressure and positive pressure treatment at a wound site. The wound dressing apparatus includes a wound dome having a substantially hollow dome interior, a manifold that is in fluid communication with the dome interior, a first passage adapted to connect to a negative pressure source to the dome interior, and a second passage adapted to connect to a positive pressure source to the manifold.
