Abstract
An arrangement for supplying a medical apparatus with anesthetic is so improved that, when changing the anesthetic supply vessel (1), the new anesthetic is made available directly and, when there is a malfunction of an anesthetic metering device (2), an exchange is possible in a simple manner. The arrangement includes a supply vessel (1) for the liquid anesthetic (6), a metering device (2) for liquid anesthetic and a pin-and-socket connection (15) between the metering component (2) and a vessel receptacle (3) of a medical apparatus (4). The metering component (2) is electrically drivable and is connected to the supply vessel (1) so as to form a modular unit.
Claims14
An anesthetic apparatus comprising:
- a housing defining a mounting surface;
- a chamber mounted in said housing;
- a plurality of plug-in supply vessels each holding a particular anesthetic and at least one of said plug-in supply vessels being placed on said mounting surface depending upon need during operational use of said anesthetic apparatus;
- each of said plug-in supply vessels including an electric metering device fixedly mounted therein so as to be an integral part of said plug-in supply vessel;
- said one plug-in supply vessel and said mounting surface conjointly defining an interface when said one plug-in supply vessel is seated on said mounting surface;
- a connector device at said interface for connecting said electric metering device to said housing to facilitate a flow of said anesthetic from said plug-in supply vessel to said chamber;
- control means for actuating said electric metering device with a pulse-width modulated control signal to open or close said electric metering device;
- and,
- an electric connector at said interface for connecting said control means to said electric metering device for conducting said pulse-width modulated control signal to said electric metering device.
A plug-in supply vessel unit for use with a medical apparatus when connected thereto, the plug-in supply vessel comprising:
- a vessel for holding an anesthetic;
- an electric metering device fixedly mounted in said vessel so as to be an integral part thereof;
- said electric metering device being configured to respond to a pulse-width modulated control signal to meter said anesthetic to the medical apparatus in a controlled manner when plugged into the medical apparatus;
- a connector device for connecting said electric metering device to the medical apparatus to facilitate a flow of said anesthetic from said plug-in supply vessel when said plug-in supply vessel is plugged into the medical apparatus;
- and,
- an electric connector element mounted in said supply vessel for conducting said pulse-width modulated control signal to said electric metering device when said plug-in supply vessel is plugged into said medical apparatus.
