An adapter for a surgical hand piece having a single lumen work tip with an open end and a small lateral hole is designed to convert the work tip to infusion/aspiration (I/A) cleanup of lens epithelial cells after phacoemulsification. The adapter is in the form of a sleeve adapted to be slid over the distal end of the work tip. The sleeve includes at least one aspiration hole located toward the distal end of the sleeve. When the distal end of the sleeve is at a first distance L.sub.1 from the distal end of the work tip, aspiration occurs through the aspiration hole of the sleeve and the open end of the work tip. When the distal end of the sleeve is at a second and smaller distance L.sub.2 from the open end of the work tip, aspiration through the open end of the work tip is blocked by the sleeve and aspiration occurs through the aspiration hole of the sleeve and the lateral hole in the work tip.

Exemplary systems for small volume collection for a breastpump system are provided. The systems allow breast milk to flow directly from the breastshield to the collection container without leaving the control volume. A valve is present outside of the milk flow path that does not contact breast milk prior to the milk reaching a collection vessel.

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 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.

A cardiothoracic drainage device includes a collection unit adapted to contain a cardiothoracic liquid drained from the chest of a patient; a main unit adapted to contain the components of the drainage device and to measure the cardiothoracic liquid contained in the collection unit; and a connection tube associated with the collection unit, with the main unit and with the drainage tube.

The main unit includes inside it: a suction pump; a normally closed electric valve; an interface component adapted to receive inputs by the user and to supply outputs for the user; an electronic control and management component adapted to control the functions of the drainage device; and a pressure sensor component operatively connected to the electronic control and management component.

A clot removal system comprises a catheter, a vacuum source, and a controller. The catheter comprises a proximal end, a distal end, and controller operating parameters and defines a lumen configured to be filled with a liquid column having a proximal portion. The vacuum source is configured to supply vacuum. The controller is configured to carry out a control pattern of turning on and off the vacuum based upon the controller operating parameters and is configured to receive the controller operating parameters in an automatic response to the catheter being operatively connected to at least one of the vacuum source and the controller and, responsive to the connection, to carry out the control pattern to change a level of vacuum at the distal end of the catheter.

The present invention provides a wound dressing tubing connector, comprising a first unit and a second unit which are releasably connectable and which when connected form a fluid path through the connector, wherein the first unit comprises an inlet and an outlet and wherein the second unit comprises an inlet and an outlet, in which the outlet of the first unit and the inlet of the second unit when connected together define the fluid path, and wherein the first unit and the second unit are connectable to form an air and fluid tight seal and wherein the first unit and/or the second unit comprises a pressure regulator valve in fluid communication with the fluid path. Also provided are systems, kits and methods of treatment.

A portable system for subatmospheric pressure therapy in connection with healing a surgical wound, including a wound dressing dimensioned for positioning relative to a wound bed of a subject and a subatmospheric pressure mechanism dimensioned to be carried or worn by the subject. The subatmospheric pressure mechanism includes a housing having a control unit adapted to draw a vacuum and a canister associated with the housing. The canister has a collection bag disposed therein, which is in fluid communication with the wound dressing to receive exudates from the wound bed. The collection bag is adapted to expand upon receipt of the fluids and has means to release gas from within the collection bag in connection with operation of the control unit. With this arrangement, the canister is attitude independent, i.e., the canister may be positioned on edge, on its side or on its end etc. while still maintaining operation of the control unit. The collection bag may include a hydrophobic vent or material for releasing the gases. In another embodiment, the collection bag comprises a gas permeable material. The collection bag may include one of pleats or bellows.

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.
