A fluid flow controller includes a first body portion defining a receiving surface, a second body portion, and a fluid transfer device. The second body portion includes a controller engagement member, and is configured to couple to the first body portion such that the controller engagement member faces and is spaced from an engagement point of the receiving surface. The controller engagement member is configured to be adjusted from a first distance to a second distance closer to the engagement point than the first distance based on a force applied by a foot pedal apparatus. The fluid transfer device defines a flow channel configured to be adjusted from defining a first cross sectional area to a second, lesser cross sectional area while the controller engagement member is in contact with the first fluid transfer device and adjusted towards the second distance in response to the applied force.

The invention belongs to the field of medical sciences and respiratory masks. It is a cardiopulmonary resuscitation device that delivers assisted ventilation via a foot- or compressor-controlled bellows mechanism. This device frees the use of the hand used to compress the conventional self-inflating Airway Mask Bag Unit (AMBU), so that the free hand can be used to fit the mask over the patient's face and reduce the mechanical fatigue generated by the manual compression of current mechanisms. The unit attaches to ventilation masks, can have a frequency meter and is compatible with accessories comprising conventional cardiopulmonary resuscitation devices; inside it has a valve that controls the filling of the oxygen reservoir and the time at which oxygen is released to be supplied to the patient.

A phacoemulsification system includes a console connected to a hand piece that has an ultrasonically vibrated cutting tip. The console generates an ultrasonic electrical signal for the cutting tip, provides irrigation fluid and is the source of aspiration force. The console also has a pressure sensor. The control system has automatic operation such that the aspiration force lowers when a first preset pressure limit is reached, and the aspiration force and ultrasonic vibration are turned off at a second preset pressure limit higher than the first. The control system also lowers the aspiration force initially when a change in pressure per unit of time exceeds a preset limit and then increases the aspiration flow if the pressure level drops below the limit.

An apparatus, system and method for providing a may include at least a phacoemulsification surgical console having a customizable non-linear custom aspiration mode. The console may include at least an aspirator; a foot pedal; and a non-transitory computing code resident on a computing memory associated with a computing processor which, when executed by the processor, causes to be executed the steps of: receiving a percentage actuation of the foot pedal; calculating, including from a non-linear algorithm, a percentage actuation for the aspirator corresponded to the received percentage foot pedal actuation; and dictating the calculated percentage aspirator actuation to the aspirator.

A manually operable pump for the effective removal of fluids to include blood, blood clots, fluid, and air from a body cavity of a subject is provided. The manually operable pump is adapted to be connect to a range of fluid conduits and is equipped with one-way valves that effectively permit flow of fluid through the pump in only one direction. The sensitivity of the one-way valves is such that when properly positioned, fluid can flow through the valves and out of the pump without manual compression of the pump and with the aid of gravity power alone.

The invention relates to an ergonomic foot pedal and to apparatuses for manual ventilation. In an embodiment, the invention provides a compact and integrated foot pedal that enables a care provider to provide positive pressure ventilation to a subject's airways and lungs, and to optionally apply suction for the purpose of aspirating mucous, secretions, meconium, blood, fluids or other such materials from a patientspecifically from airways.

A respiratory device includes a blower having an inlet and an outlet, a patient interface, and a valve including a valve member that is rotatable from a first position to a second position. The outlet of the blower is coupled to the patient interface so that positive pressure is provided to a patient's airway via the patient interface when the valve member is in the first position. The inlet of the blower is coupled to the patient interface so that negative pressure is provided to the patient's airway via the patient interface when the valve member is in the second position. The valve member is rotatably oscillated back and forth when the valve member is in the first position and when the valve member is in the second position so that oscillations in the positive pressure and negative pressure, respectively, are provided to the patient's airway.

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.

The present invention includes an apparatus and method for a hands-free foot pedal to attenuate and interrupt suction that attaches externally around suction tubing, in the context of any system where the flow of suction is through tubing.
