A system for administering regional anesthesia to a patient contains a regional anesthesia catheter and a partially splittable needle. Meanwhile, a function value-corresponding to-flow end that is a boundary value of the cumulative distribution function to be considered as a flow end in the range of a cumulative distribution function value is stored. A pre-processor is provided to carry out initial processing tasks on a received data set to make it more susceptible to structural processing according to the conversion rules, and a post-processor is provided to carry out tasks such as vocabulary and data type conversion. The body is folded about each uncut edge so that the ends of the body meet at a corner. For example, the electrodes may be immersed in an electrolyte to construct electrochemical double layer capacitors. A secondary display is also provided on which a scorecard, indicating prizes to be paid upon a winning game being achieved, is displayed.
