Ophthalmological patient interface

Disclosed is a patient interface for affixment on onto a patient eye, said patient interface including:

The invention relates to a negative-pressure device () for affixing a patient interface () with a negative-pressure cavity () onto a patient eye. The negative-pressure device () comprises a negative-pressure generator () and a pressure sensor () with a device-side pressure sensor interface () for coupling the pressure sensor () to the negative-pressure cavity in a manner fluidically separate from the negative-pressure interface (). The negative-pressure device furthermore relates to a control unit () operatively coupled to the negative-pressure generator () and the pressure sensor (), wherein the control unit () is designed to detect a faulty fluidic coupling of the negative-pressure cavity () by evaluating a pressure established by the pressure sensor (). The invention furthermore relates to a patient interface () with a negative-pressure cavity (), wherein the negative-pressure cavity () has a negative-pressure interface and a fluidically separate pressure sensor interface, as well as a patient interface with an integrated pressure sensor. The invention furthermore relates to a method for coupling a patient interface () to a patient eye.

Ophthalmological negative-pressure device and patient interface

A patient interface for coupling an ophthalmological application head to an eye of a patient includes a patient-sided interface structure to be coupled to the eye of a patient, and a source-sided interface structure for rigidly coupling the patient interface to the application head or an intermediate element. The source-sided interface structure comprises a first source-sided patient interface coupler and a second source-sided patient interface coupler. The first source-sided patient interface coupler is designed to restrict the mobility of the patient interface relative to the application head or the intermediate element by providing a coupling with a first patient interface coupler counterpiece of the application head or the intermediate element. The second source-sided patient interface coupler is designed to rigidly couple the patient interface to the application head or the intermediate element while the first source-sided patient interface coupler is coupled with the first patient interface coupler counterpiece.
