An anesthesia system for providing a breathing gas enriched with anesthetic has an anesthesia apparatus (2) and at least one anesthetic dispensing device (3), which is detachably coupled with the anesthesia apparatus. A fluid connection (7, 8, 9) is provided between the anesthesia apparatus and the dispensing device, which is designed to send anesthetic from the dispensing device into the anesthesia apparatus. At least one optical interface is provided between the anesthesia apparatus and the dispensing device. At least one display device is provided in the dispensing device. The optical interface has at least one light source (10), which is provided in the anesthesia apparatus, and at least one fiber optic light guide (20), which is provided in the anesthetic dispensing device (3). The light fed by the light source (10) into the fiber optic light guide is sent to the display device to directly or indirectly light the display device.

An anesthesia machine includes an interface for receiving a vaporizer, a housing having an outer surface, a button having an outer surface, and configured to receive an engagement force from a user, and a latch including an engagement portion, and configured to selectively secure the vaporizer to the anesthesia machine via the engagement portion according to a position of the button, wherein a positional relationship between the outer surface of the button with the outer surface of the housing indicates whether or not the vaporizer is correctly received by the interface of the anesthesia machine

Systems and methods are provided for detecting unacceptable accelerations by an anesthetic vaporizer, such as due to drops and mishandling. In one embodiment, a method for an anesthetic vaporizer comprises determining a quantitative acceleration of the anesthetic vaporizer based on acceleration vectors measured by an accelerometer coupled within the anesthetic vaporizer, and outputting an alert responsive to the quantitative acceleration exceeding an acceleration threshold. In this way, drop-related degradation may be identified in a timely fashion.
