A wearable and hidden breast pump includes a shell, a flange, a negative pressure chamber, a negative pressure pump, a milk container and a solenoid valve. The flange is arranged on a front surface of the shell; the negative pressure chamber is arranged in the shell and connected with the flange to form an lactation chamber; the negative pressure pump and the solenoid valve are arranged in the shell, the negative pressure pump, the solenoid valve and the negative pressure chamber are communicated; the negative pressure pump intermittently extracts air from the negative pressure chamber, and the solenoid valve intermittently inflates air into the negative pressure chamber, thus controlling an air amount in said negative pressure chamber, thereby controlling the lactation chamber to form a negative pressure or a positive pressure; the milk container is arranged under the shell and communicated with the lactation chamber.

A surgical system includes an electrosurgical tool configured to be releasably coupled to a surgical robotic system having a control system. The tool has a shaft having an end effector with treatment electrodes configured to apply electrosurgical power to a tissue, and aspiration and irrigation tubes having ports in the vicinity of the electrodes. The control system can control a flow rate of an irrigation fluid based on deviation of power delivered by the electrodes to the tissue from a power set point, or based on an aspiration rate that is controlled based on tissue impedance. The tool can have first and second ports and a conduit configured to selectively provide or aspirate fluids through at least one of the ports. At least one of a flow rate and an aspiration rate are controlled by the control system based on a rotational angle of the shaft relative to a ground.

Embodiments of the present invention relate to the field of pressurized fluid delivery devices for use in medical procedures. In particular, a fluid delivery pump comprises at least one compressive member configured to apply a force to a fluid reservoir. The at least one compressive member is associated with a flexible envelope, such that the flexible envelope may move the compressive member. The flexible envelope may be substantially air-tight so that it may be pressurized. When a negative pressure is created inside the flexible envelope, the flexible envelope may change volume, applying a force to the at least one compressive member. The at least one compressive member may then apply a force to the fluid reservoir and the fluid is forced out of the reservoir.

Devices, systems, and methods for treatment of an eye alter aspiration flow from the eye in response to an occlusion of the aspiration conduit pathway. Where aspiration is drawn from the eye using a volumetric pump, the pump can be reversed so as to induce fluid reflux from the aspiration conduit pathway into the eye to help clear the occlusion. The pump may vary the reverse flow in response to sensed aspiration pressure or the like, and the reverse flow may be halted before the pressure within the aspiration conduit pathway adjacent the eye significantly exceeds the irrigation fluid pressure and/or the pressure within the eye. Reflux may alternatively be generated by modulating a vent valve disposed between an irrigation conduit pathway and the aspiration conduit pathway.

A portable suction device comprising: a gas inlet for receiving pressurized gas from an enclosed source; a gas flow path that extends from the gas inlet to an exhaust; a suction generator that has a suction inlet, the gas flow path extending through the suction generator, such that gas flow through the flow path generates a low pressure at the suction inlet; a collection container with a collection inlet and an outlet that is coupled to the suction inlet; a suction tube that has proximal and distal ends, the proximal end being connected to the collection inlet of the collection container; a valve for controlling gas flow through the flow path, the valve having a stem that is configured to pierce the source with movement of the valve from a closed position.

A medical waste collection system includes a medical waste collection device for providing suction at a surgical site, and a manifold releasably couplable to the medical waste collection device. The manifold defines a pathway through which the medical waste collection device is configured to provide suction to the surgical site. The medical waste collection device is configured to control activation of suction based on a proper manifold being present.

An anti-clog suction tip apparatus includes a suction tip having a suction opening and an interior defining a suction channel. An ejection wire channel extends to a wire exit opening into the suction channel that is located proximate the suction opening. An ejection wire including a ball tip at an end thereof occupies the ejection wire channel and is transitionable between a retracted configuration and an advanced configuration such that, in the retracted configuration, the ejection wire including the ball tip is retained within the ejection wire channel and does not obstruct suctioning of debris through the suction channel; and in the advanced configuration, the ball tip of the ejection wire does not extend more than three millimeters beyond the suction opening.
