An aspiration system includes a pump and a control system in communication with the pump. The control system includes a microcontroller, an antenna configured to receive a signal, and a pump control board in communication with the microcontroller. The antenna is in communication with the microcontroller. Upon receiving the signal, the pump control board operates the pump to create negative pressure according to the signal.

Disclosed is a chest drainage system which reduces or eliminates pooling of blood/liquid and/or clogging/clotting in the drainage tube and/or chest tube, and provides objective and accurate measures of drained fluid volume and chest air leak. The chest drainage system continuously monitors chest tube and drainage tube status and clears pooled liquid in the drainage tube, and/or a clogged chest tube when necessary to restore negative pressure to the chest.

A pre-evacuated container for medical purposes includes an outer body that forms an internal cavity, wherein in a default state the internal cavity is at a vacuum pressure relative to atmosphere, and a fluid interface on the outer body that connects to a drainage tube. A pressure indicator on the outer body is adapted to provide an indication as to a fluid pressure state of the internal cavity. An outlet assembly can be actuated to form an opening between atmosphere and the internal cavity, wherein the outlet assembly can be actuated without damaging the outer body.

A system for detecting intraocular pressure events during phacoemulsification surgery having a surgical console, a handpiece having a proximal end being communicatively connected to an irrigation line and an aspiration line; a first sensor in communication with the aspiration line or the irrigation line for providing a first measurement value; and a second sensor in communication with the aspiration line for providing a second measurement value; and wherein at least one characteristic of the irrigation fluid or aspiration fluid in their respective lines is changed in accordance with the difference between the first measurement value and the second measurement value. A system for calibrating patient eye level and wound leakage; detecting occlusion or post occlusion surge; determining BSS usage or remaining in a container; and detecting a fluid line abnormality using a first sensor and a second sensor in different configurations and differences in first and second measurement values.

Systems for maintaining a vacuum in a patient's oral cavity comprises an oral device, a vacuum control system, and an assembly including first and second tubes for connecting the vacuum control system to the oral device. The oral device has an internal plenum, and a vacuum is drawn in the plenum by a vacuum pump connected by a first tube of the tubular assembly. The vacuum is maintained by an air source which is connected to the plenum by the second tube of the tubular assembly. By maintaining a constant circulating air bleed through the oral device and the connecting tubes, saliva may be removed from the system and collected in a saliva trap located before the vacuum pump.

A flow control system may include an inner nosecone having an inner nosecone distal end and an inner nosecone proximal end, an outer nosecone having an outer nosecone distal end and an outer nosecone proximal end, an aperture of the outer nosecone, a gasket having a gasket distal end and a gasket proximal end, a gasket aperture of the gasket, a gasket seal of the gasket, a flow control mechanism having a flow control mechanism distal end and a flow control mechanism proximal end, and a control aperture of the flow control mechanism. A rotation of the flow control mechanism about the gasket may be configured to decrease an aspiration flow rate. A rotation of the flow control mechanism about the gasket may be configured to increase an aspiration flow rate.

An apparatus such as a suction instrument includes a position sensor proximate to a distal tip of a malleable shaft. A sensor wire couples the position sensor to a processor of an image guided surgery system such that signals generated by the position sensor can be interpreted to determine the position of the surgical instrument. The malleable shaft includes a malleable outer shaft and a flexible inner tube. The flexible inner tube includes a primary lumen that can provide suction, fluid, or various deployable surgical tools, and an inner lumen that holds the sensor wire. Protected within the inner lumen, the sensor wire runs the length of the shaft and exits the inner lumen and passes through a slot in the outer shaft to reach the position sensor. A heat shrink cover wraps the distal tip, sealing the components together and providing an opening suitable for suction.

A portable suction system including a pump device and a removable bag device. The pump device includes a housing defining a recess; a motor assembly positioned within the housing; a first rod at least partially extending from the housing into the recess; and a second rod at least partially extending from the housing into the recess. The first rod and the second rod are driven in response to energization of the motor assembly. The bag device is at least partially positioned within the recess, and the bag device includes: a bag; a vacuum connector; a first piston coupled to the first rod; and a second piston coupled to the second rod.

A waste collection unit for collecting waste material. First and second waste containers are supported on a portable cart. A control panel is configured to receive one or more inputs of selectively set vacuum levels in the first and/or second waste containers. A control system controls operation of vacuum regulators based on the input(s) to regulate levels of vacuums being drawn in each of the waste containers. Pressure sensors in communication with the control system may be positioned to monitor pressure in the waste containers. A back up port support on the portable cart may be provided to receive a vacuum line for coupling a vacuum manifold to a remote vacuum source not located on the portable cart. Container lamps may be coupled to the first and/or second waste containers and configured to illuminate the waste material within the waste containers to be viewed through transparent windows.

An irrigation tool that includes a handle configured for grasping by a hand of a user of the tool having a handgrip displaceable using the hand in a manner that selectively controls the rate of flow of irrigation fluid discharged from the tool. The handgrip includes a compressible chamber mounted to the handle via at least one fluid coupling with the chamber compressible by manually squeezing the handgrip to discharge irrigation fluid. The chamber can be provided by a bulb in operable cooperation with a fluid coupling that provides an irrigation fluid flow-modulating control valve arrangement responsive to the magnitude and rate of applied squeezing force. The tool can include an aspirator having a suction passage integrally formed in the handle with a suction control valve operable using the same hand used to control irrigation fluid flow producing a hand-held hand operated combination irrigation and suction tool.
