Abstract

An anesthetics monitoring device includes an anesthetic vaporizer, from which the anesthetic can be supplied to a setting device supplying dosed amounts of anesthetic to an anesthetics device for dispensing the anesthesia to a patient. The device has a coding for the unmistakable assignment of the setting device to the type of anesthetic used. An automatic recognition of the anesthetic used and a setting to a metering and control unit for dispersing the anesthetic is guaranteed. Any incorrect metering and incorrect setting is prevented. For this purpose, the coding is brought into an operative connection with a receiver provided between the setting device and the anesthetics dispersing device. The receiver is equipped with a scanning apparatus which is connected to the metering and control dispensing unit by means of signal transfer lines.

Claims

1. An anesthetic control device, comprising:

an anesthetic vaporizer device including an amount of a predetermined anesthetic;

setting means connected to said anesthetic vaporizer device for setting a predetermined concentration ratio of anesthetic for administration to a patient;

anesthetic coding means connected to said anesthetic vaporizer device for providing information representing a type of the predetermined anesthetic in said anesthetic vaporizer device;

anesthetic code receiving means operatively connected to said anesthetic coding means for receiving said information representing said type of predetermined anesthetic in said anesthetic vaporizer device;

a metering and control unit connected to said anesthetic code receiving means;

a setting device coding means connected to said setting means for providing a setting code representing information of said concentration ratio of anesthetic being administered by said anesthetic vaporizer device to the patient; and

,

setting code receiving means operatively connected to said setting device coding means for receiving said setting code, said setting code receiving means being connected to said metering and control unit.

2. An anesthetic control device according to claim 1, wherein:

said anesthetic coding means includes a plug member with a plurality of control form parts having a predetermined shape, and said shape of each of said control form parts cooperating to define said anesthetic coding means;

said anesthetic code receiving means including a coupling element for coupling with said plug member, said coupling element including recesses for receiving said control form parts; and

,

signal emitter means associated with said coupling element for detecting a presence of said control form parts and providing a signal representing said information to said metering and control unit.

3. An anesthetic control device according to claim 1, further comprising:

another anesthetic vaporizer device positioned adjacent said anesthetic vaporizer device, said another anesthetic vaporizer device including another setting means;

a stopping element for engaging said setting means of one of said anesthetic vaporizer device and said another anesthetic vaporizer device for preventing one of said anesthetic vaporizer device and said another anesthetic vaporizer device from providing amounts of anesthetic; and

detection means for sensing the position of said stopping element and for detecting zero flow of anesthetic from one of said anesthetic vaporizer device and said another anesthetic vaporizer device.

4. An anesthetic control device according to claim 1, wherein:

said metering and control unit includes a memory for storing and retrieving information corresponding to said anesthetic vaporizer device and the predetermined anesthetic.

5. An anesthetic control device according to claim 4, wherein said metering and control unit is connected to said anesthetic vaporizer device.

6. An anesthetic control device in accordance with claim 4, wherein:

said metering and control unit also includes a central processing unit for processing said information from said memory and information from said anesthetic code receiving means and setting code receiving means; and

means for displaying said information from said memory, information from said code receiving means, and setting code receiving means and results of processing by said CPU.

7. An anesthetic control device in accordance with claim 6, further comprising:

a mixing means on said support for further adjustment of said anesthetic concentration ratio; and

said metering and control unit also controlling said mixing means.

8. An anesthetic control device, comprising:
