Operating element and method for input of values in a medical device

Abstract

Each manual interface (3, 4, 5) or control used to operate the apparatus includes a display of the actual value to which it is set. This value can be changed in response to a contact value from the contact sensor. The sensor is capacitative and is fitted underneath a dielectric cover. Operation is effected by touching the surface with the finger, and / or by sliding it along the surface. The operating surface has point-, line- or circular form. The actual value is shown during adjustment, whilst marks on or near to the touch surface, indicate the adjustments in value. Independent claims are included for the following: (A) the method; (B) and medical apparatus.

Description

technical field [0001] The invention relates to an operating element and a method for inputting values ​​into a medical device according to independent claims 1 and 7 . Furthermore, the invention relates to a medical device which is equipped with such an operating element and with which the method according to the invention can be carried out. Background technique [0002] In the prior art it is known to enter values ​​and parameters into medical devices such as injection devices, surgical devices, respiratory devices or dental devices by means of joysticks, buttons or rotary handles, for example to control the supply of medicaments or breathing air or to control drill speed. The disadvantage of these operating elements is that dirt and bacteria can collect on the boundary surfaces between the operating elements such as buttons or switches and the surface of the medical device, which makes it difficult to achieve reliable cleaning and disinfection of these surfaces, or sign...

AI Technical Summary

Problems solved by technology

The disadvantage of these operating elements is that dirt and bacteria can collect on the boundary surfaces between the operating elements such as buttons or switches and the surface of the medical device, which makes it difficult to achieve reliable cleaning and disinfection of these surfaces, or significantly limits this. cleaning operation

[0003] Furthermore, with conventional switches, levers, buttons or rotary handles, only individual functions of the medical device can be activated, i.e. for example the rotational speed of the drill can be set with the corresponding rotary handle, but not the simultaneous supply of refrigerant fluid

[0004] Another disadvantage of conventional operating elements is that the adjustment of the current value only takes place linearly, and in order to change the current value, the physician must first grasp the appropriate lever or rotary handle of the operating element at the exact point at which the current value is located, thereby turning the operating The lever or handle is moved or rotated to the point where the value will be set and desired by the physician

[0005] Finally, traditional operating elements are often difficult to identify and there is a risk of a short circuit in the device being transmitted to the operator by the operating elements coupled inside the device and possibly causing injury
