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. 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 support may be a telescoping member with the first element including a detent and the detent engaging the second element. Further, the detent may be biased toward engagement with the second element. |
