Operating element and method of inputting values into a medical apparatus
First Claim
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.

Abstract
The present invention relates to an operating element and a method of inputting values into a medical apparatus (1), having a touch-sensitive sensor (19) and an operating surface (22), the sensor (19) being mounted below a cover (20) forming the operating surface (22), which detects the presence or absence of an operating means (11) and generates a contact value (17). A display (14) of the operating element shows a current value (16), which is variable by means of the contact value (17) of the sensor (19) to a value (15) to be set. Advantageously, the current value (16) can be varied by means of contact of the operating surface (22) to any point or to a point which corresponds to the value (15) to be set, respectively depending on the manner of contact of the operating surface (22).
