Abstract: A patient monitor has an information processor, an information display, a control or selector. The information processor is programmable and re-programmable according to a user's requirements. The sockets are substantially identical with a number of socket connectors and are electrically connected in parallel with one another. The sensor sockets and the sensors have connectors that connect when the sensors are plugged into the sockets. Not all of the connectors are used by a sensor, however, so the patient monitor identifies and differentiates each sensor not by which socket it is plugged into, but by which plug and socket connectors are used. In other aspects, the invention includes an expansible medical suction canister having an expansible chamber and a support. The chamber is expandable to an open position and compressible to a closed position. The chamber also has opposing first and second ends.

Abstract: A patient monitor has an information processor, an information display, a control or selector, at least two sensor sockets, and at least two patient sensors. The information processor is programmable and re-programmable according to a user's requirements. The sockets are substantially identical with a number of socket connectors and are electrically connected in parallel with one another. One of the sensors monitors one aspect of a patient's condition and generates a signal to the information processor accordingly. A second sensor monitors a second aspect of a patient's condition and generates a signal to the information processor accordingly. Each of the patient sensors plugs into any of the sensor sockets. The sensor sockets and the sensors have connectors that connect when the sensors are plugged into the sockets.

Abstract: An expansible medical suction canister has an expansible chamber and a support. The chamber is expandable to an open position and compressible to a closed position. The chamber also has opposing first and second ends. The first and the second ends are spaced relatively farther apart in the open position than in the closed position. The support is connected between the opposing ends and moves with the opposing ends between the open and closed positions. The support also has a locked condition in the open position. The support may have a first element and a second element. The first and the second elements preferably move between open and closed positions with the opposing chamber ends. In one aspect, the first element may have a stop surface and the second element may include a leg with an end that abuts the stop surface in the open position, whereby compression of the canister to the closed position is resisted.

Abstract: A medical irrigation pump and system for providing simultaneous controlled fluid flow from a plurality of reservoirs. The system is disposed to flow fluid sequentially from the reservoirs or to flow fluid simultaneously from two or more of them. This is accomplished by providing fluid in a plurality of bags or pliable containers which are then subjected to controlled pressures to force the fluid therefrom either simultaneously or sequentially, thereby providing versatility and enhanced liquid flow capability.
