Ophthalmic surgical devices, systems, and methods for regulating aspiration from a patient's eye are provided. A vacuum pump in fluid communication with an aspiration line provides fluid aspiration from a vitreous chamber of the eye through the aspiration line. A sensor disposed adjacent to or inside the eye determines sensor data relating to an intraocular pressure (IOP). The controller receives the sensor data and regulates the aspiration in response to changes in the TOP, such as by controlling the vacuum pump. The controller may determine whether a fluid infusion to the vitreous chamber through an infusion line is below a maximum infusion level, regulate the infusion in response to the TOP being below a threshold value and the infusion being below the maximum infusion level, and regulate the aspiration in response to the TOP being below the threshold value and the infusion being at or above the maximum infusion level.

A flushing pump including: a pump configured to draw fluid from a reservoir and expel the drawn fluid from a fluid outlet; a processor configured to control operation of the pump; and a remote controller connection port in electrical communication with the processor. The remote controller connection port including: an output system connection point; an input system connection point; a debugging connection point; and a ground connection point held at a reference voltage level. Wherein the processor is configured to output diagnostic information to the output system connection point in response to the debugging connection point receiving a signal at the reference voltage level.

Systems, devices, and methods related to wound therapy are disclosed. Different aspects of wound care, including mechanical wound therapy, wound monitoring, irrigation, debridement, and delivery of therapies to the wound surface can be combined to improve effectiveness of treatment. The disclosed techniques can provide various type of clinical applications of wound therapies, including reverse pulse lavage, gas therapy, bacterial count measurements, pressure-based ulcer prevention, pain management, peritoneal dialysis, and controlled tissue in-growth, among others. In some instances, the systems described herein can be made portable and operable without the use of electricity, which provides potential to provide mechanical wound therapy in settings without access to extensive clinical facilities.

A negative pressure wound treatment system comprising a bandage portion and a negative pressure portion. The bandage portion includes a dressing portion in contact with a wound and a sealing layer positioned in contact with the dressing portion. The sealing layer includes an adhesive creating a seal around the wound. The negative pressure portion is in fluid communication with the bandage portion and includes a first valve and a second valve. The first valve is in fluid communication with the bandage portion and the negative pressure portion. The second valve is in fluid communication with the negative pressure portion and the surrounding environment. The negative pressure wound treatment system is configured to provide negative pressure to an area sealed by the bandage portion upon the actuation of the negative pressure portion. The negative pressure portion is configured to be actuated by compressing the negative pressure portion while walking.

Provided is a new ventilator that can be used for pulmonary resuscitation without requiring an electrical driving source. A ventilator includes a housing. The housing has an input port through which a gas is introduced into the housing, a main port through which the gas that is to be sent to and inhaled by a patient and a gas that is exhaled by the patient pass, an exhaust port through which the gas inhaled or the gas exhaled is exhausted from the housing, a ventilation path connecting the input port and the main port to each other, and a relief valve that is opened by receiving a pressure from the ventilation path and that allows communication between the ventilation path and the exhaust port so as to release the pressure.

Proposed is a system for operating a syringe. The system includes an apparatus for operating a syringe in which a syringe filled with one or more fluids is mounted and that includes a motor configured to selectively discharge the one or more fluids filled in the syringe by moving forward and backward a piston of the syringe, and a controller configured to control movement of the piston of the syringe through the motor, in which the controller moves the piston to follow a predetermined motion on the basis of a set mode when recognizing a request to operate or stop the apparatus for operating a syringe.

Certain aspects of the present disclosure provide a surgical system comprising a fluid output device capable of connecting to a syringe comprising a material for delivery to a body part through a cannula connected to the syringe and a controller configured to adjust a pressure of the fluid output to enable a controlled delivery of the material within the syringe at a target flow rate.

A negative pressure wound treatment system comprising a bandage portion and a negative pressure portion. The bandage portion includes a dressing portion in contact with a wound and a sealing layer positioned in contact with the dressing portion. The sealing layer includes an adhesive creating a seal around the wound. The negative pressure portion is in fluid communication with the bandage portion and includes a first valve and a second valve. The first valve is in fluid communication with the bandage portion and the negative pressure portion. The second valve is in fluid communication with the negative pressure portion and the surrounding environment. The negative pressure wound treatment system is configured to provide negative pressure to an area sealed by the bandage portion upon the actuation of the negative pressure portion. The negative pressure portion is configured to be actuated by compressing the negative pressure portion while walking.

A pressure regulating or pressure relief device comprises an inlet and an outlet chamber with an outlet. The inlet is in fluid communication with the outlet chamber. A valve seat is located between the inlet and the outlet. A valve member is biased to seal against the valve seat, and displaces from the valve seat by an inlet pressure at the inlet increasing above a pressure threshold to allow a flow of gases from the inlet to the outlet via the outlet chamber. The flow of gases through the outlet causes an outlet pressure in the outlet chamber to act on the valve member together with the inlet pressure to displace the valve member from the valve seat.

A fluid management system for an endoscopic procedure including: a pump configured to deliver liquid from a reservoir to a medical device; a processor comprising hardware, the processor being configured to control operation of the pump; a footswitch in communication with the processor, the footswitch being configured to actuate the pump; and a user input device configured to program the processor to operate the pump at a plurality of predetermined levels of an operational parameter of the pump and to allow a user to select one of the plurality of predetermined levels for pump operation, wherein the processor is further configured to disable at least parts of the user input device when the footswitch is engaged.
