Abstract:
1. Operating element for inputting values into a medical apparatus, having a touch-sensitive sensor and an operating surface, the sensor being mounted below a cover forming the operating surface, wherein the sensor detects the presence or absence of an operating means and generates a contact value in response thereto, characterized in that a display of the operating element displays a current value which may be changed, by means of the contact value generated by the sensor, to a value to be set; characterized in that the current value is set and displayed continuously or step-wise and is variable independently of a point of presence or absence of the operating means; characterized in that the touch-sensitive sensor is a capacitive sensor, which is mounted below a dielectric cover, and in that the sensor is responsive to a human finger; characterized in that in order to set the value to be set, the operating means can be placed and/or displaced to any position on the operating surface, wherein the setting can be an absolute setting, a relative setting and/or a dynamic setting; and wherein the at least one operating element has an operating surface in the form of a dot, a line or a circle, which is applied to an operating panel for inputting flow rates and/or flow strengths for medicaments or flushing liquids or for the input of other medicinal parameters.
