Abstract

Abstract This specification discloses a slide rule guide intended for use in intravenous therapy to aid a doctor or nurse in determining the character and quantities of materials to be injected into a patient''s vein and the intervals between such injections as determined by the weight and condition of the patient. The guide consists essentially of an envelope providing two outer panels and a slide in said envelope presenting two effective faces. One of the panels is formed with a small opening with which is associated the designation ''''Body Weight'''', while one face of the insert displays a series of figures corresponding to weights of patients and any one of which may appear in said opening. The exposed face of each outer panel is divided into four rectangular sections. Each of these sections on one face is formed with an opening for body weight designation and the face of the slide, opposite to that mentioned above, carries four series of figures for weight designation, each of which cooperates with one of the openings in this panel. Each section of each outer panel displays the heading for patient condition. Below this heading in each section are two windows in vertical alignment. Associated with one of these windows is a table for ''''Estimated 24 Hr. Therapy'''' and associated with the other window is a table for ''''Treatment Guide''''. Each face of the slide displays four groups of figures, each comprising a plurality of rows with the figures in the several rows in vertical alignment and any such vertically aligned figures may appear in the windows of a respective panel when the slide is moved relative to the envelope.
