Handheld device with activation switch for patient-controlled analgesia

Abstract

A handheld device for patient-controlled analgesia includes a handle configured to be gripped and held by a patient with one hand. The handle encloses or defines a volume with a center of volume. The handle includes a first handle section configured to be gripped by a thumb and an index finger or a middle finger of the patient in such a way that an activation switch provided on a first large surface of the handle can be actuated by the patient’s thumb while the patient’s index finger or middle finger can be brought into contact with a defined finger recess provided on a second large surface of the handle. The handle has a center of mass which is offset relative to the center of volume of the handle in a direction away from the first handle section and is located in a second handle section of the handle.
