A method may be provided for the operation of a pump device, which comprises at least one pump as well as a suction element which is connected to the at least one pump and which has a suction opening positioned in a cavity of a body of a patient that sucks a fluid by way of producing a reduced pressure in the suction element, wherein an acceleration is measured and monitored during the operation of the pump device, wherein the reduced pressure in the suction element is reduced at least for a limited reaction time period, given the occurrence of an acceleration variable which lies above a fixed threshold valve. A correspondingly configured pump device may be provided.

A wound treatment appliance is provided for treating all or a portion of a wound. In some embodiments, the appliance includes an impermeable flexible overlay for applying a reduced pressure to the covered portion of the wound. The wound treatment appliance may also include a vacuum system to supply reduced pressure to the wound in the area under the flexible overlay, a wound packing means to prevent overgrowth of the wound or to encourage growth of the wound tissue into an absorbable matrix including the wound packing means, a suction drain, a collection chamber to collect and store exudate from the wound, and/or a suction bulb which 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.

Systems and methods for delivery of fluid to a wound therapy dressing. In exemplary embodiments, a pressure sensor measures the pressure at the wound therapy dressing and restricts fluid flow to the wound therapy dressing when a predetermined pressure is achieve.

Apparatus and methods are provided for applying negative pressure to tissues of a patient that are transmitted to the vertebral venous system of the patient and thereby lowering intracranial pressure. Intracranial pressure is thus lowered easily without increasing the work of breathing, without needing to be intubated, and without breathing through a valve in patients with elevated increased intracranial pressure.

An operating room control system that is soft configurable allowing a user to completely configure the control and function of the system. The system includes a touchscreen that provides a video display received from a video endoscope and presents icons on the touchscreen allowing the user to control and interface with the tools/equipment in the operating room as well as hospital systems. The controls, displays, tools, equipment, etc. are configured to be operated from a single centralized platform.

The present disclosure illustrates a sensor-controlled nasal aspirator including a distance sensing unit, a micro processing unit and an air pump. The distance sensing unit is configured to sense a distance between a target object and the distance sensing unit. The micro processing unit is configured to store a preset distance, and receive and process the distance transmitted from the distance sensing unit, and transmit an action command signal when the distance is not higher than the preset distance. The air pump is configured to receive the action command signal and performs a target action according to the action command signal.

A device for extracting lens material from an eye including a distal, disposable portion releaseably coupleable to a proximal, reusable portion. The disposable portion includes a cutting tube having a distal cutting tip and an inner lumen having a distal end. The disposable portion includes an aspiration pump fluidly coupled to the inner lumen of the cutting tube and a cutting tube drive mechanism configured to oscillate the cutting tube. The reusable portion includes an aspiration pump motor configured to drive the aspiration pump and a coupler for releaseably operatively coupling the pump motor to the aspiration pump. Related devices, systems, and methods are disclosed.

A surgical drain system for use during and following surgery is provided. A collection reservoir is placed in fluid communication with the body of a user through a collection port. A pump creates a vacuum pressure to urge fluid into the collection reservoir. Fluid exits the collection reservoir through a drain port. A drain mechanism allows air to come into the collection reservoir through an air intake aperture and collected fluid to leave the reservoir simultaneously. The drain system can be worn beneath clothes.

A negative pressure device for applying to skin is configured to define a sealed enclosed three-dimensional space when at least a portion of the device is sealed against the skin. The device includes a body including at least one expandable segment that is configured to expand after the device has been sealed against the skin.

A chemical pump assembly useful for negative pressure therapy includes a chemical pump housing having an inner chamber, a reactor located within the inner chamber, an opening provided in the chemical pump housing, a first pull tab which extends from the inner chamber to ambient through the opening, and a removable layer connected to the first pull tab. The reactor is configured to react with a selected gas found in air so as to consume the selected gas when exposed to air in the inner chamber. The removable layer shields the reactor from air in the inner chamber atmosphere until the removable layer is removed.
