SLIDE RULE GUIDE TO INTRAVENOUS THERAPY
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.

Description
The present invention relates to a slide rule guide to intravenous
therapy and is concerned primarily with a guide which may be
readily used by a doctor, nurse or other attendant giving
intravenous therapy to readily ascertain the character and
quantities of materials or medicines which are to be injected into
a patient's vein and the interval between such injections.
BACKGROUND OF THE INVENTION
At the present time, intravenous therapy is now widely practiced.
Such therapy involves the injection of certain materials into a
patient's vein with the quantity of the material being determined
by the patient's weight, the intervals at which the injections are
made, and the particular condition being treated.
There are eight well recognized conditions which are treated by
intravenous therapy. One of these is normal maintenance, in which
there is no dehydration. Another is moderately severe isotonic
dehydration. A third is moderately severe hypotonic dehydration; a
fourth is moderately severe hypertonic dehydration; a fifth is
pyloric stenosis with mild dehydration; a sixth is pyloric stenosis
with moderately severe dehydration; a seventh is severe diabetic
acidosis and dehydration, and an eighth is renal shut-down
(anuria).
Under present day conditions, when a patient is to be subjected to
intravenous therapy, the doctor or nurse, after identifying the
patient's weight and the particular condition being treated, must
refer to various tables or catalogues to determine in the first
instance the particular materials to be injected, secondly the
quantities of each of the materials for the injection, and finally
the intervals at which injections should be made. This need for
referring to various compilations is carried out only with a high
degree of inconvenience.
OBJECTS OF THE INVENTION
With the foregoing conditions in mind, the present invention has in
view the following objectives:
1. To provide a slide rule guide to intravenous therapy which may
be manipulated with a high degree of simplicity to indicate the
nature and quantities of materials to be injected into a patient's
vein, the prescribed intervals as determined by the body weight of
the patient and the condition being treated.
2. To provide a slide rule guide of the character aforesaid which
consists essentially of an envelope providing two outer panels and
a slide within said envelope presenting two effective faces.
Various other more detailed objects and advantages of the invention
such as arise in connection with carrying out the above ideas in a
practical embodiment will, in part, become apparent, and, in part,
be hereafter stated as the description of the invention
proceeds.
SUMMARY OF THE INVENTION
The foregoing objects are achieved by providing a slide rule guide
conprising an envelope consisting of two outer panels which are
separately identified such as panel "A" and panel "B" and a slide
within said envelope presenting two effective faces which are
separately identified in a manner corresponding to that of the
identification to that of the panels, thus, "Side A" and "Side
B".
One of the panels, such as side A is marked off to define a top
margin and four rectangular sections therebeneath. Formed in this
top margin is a small opening with the term "Body Weight" on one
side and a unit of weight on the other side. Side A of the slide,
which is intended to cooperate with panel side A displays a series
of figures, any one of which will closely approximate the weight of
a patient and which will appear in said opening when the slide is
properly adjusted in the envelope.
Panel side B is marked off into four rectangular sections, each of
which is formed with a small opening with the term "Body Weight" on
one side thereof and a designation of unit of weight on the other.
Side B of the slide which cooperates with panel side B displays
four series of figures, with each figure approximating the weight
of a patient and any figure of which will appear in the small
opening when the slide is properly adjusted. Each rectangular
section of each outer panel displays a heading indicating the
condition being treated. Below this heading each section is formed
with two windows in vertical alignment. A table for estimated 24
hour therapy is associated with one window and comprises the names
of the materials on one side of the window and units of quantity on
the other side. A table for treatment guide is associated with the
other window and comprises an identification of a particular
material on one side of the window, units of quantity on the other
side, and time intervals on the latter side. Both faces of the
slide display groups of figures which in a sense might be said to
be complemental to the tables on the sections of the outer panels.
Thus, when the slide is moved to bring a weight designation thereon
into alignment either with the single opening on side A of the
panel or one of the four openings on side B of the panel, depending
on the condition being treated, the number of units of quantity for
each material will be displayed in one of the windows.
For a full and more complete understanding of the invention,
reference may be had to the following description and the
accompanying drawings wherein:
FIG. 1 is a perspective of a slide rule guide to intraveneous
therapy embodying the precepts of this invention and depicting the
slide on a scale less than that of actual size;
FIG. 2 is a plan view of one side of the slide;
FIG. 3 is a plan view of the other side of the slide;
FIG. 4 is a plan view of one of the outer panels, and
FIG. 5 is a plan view of the other of the outer panels.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings, wherein like reference characters
denote corresponding elements throughout the several views, the
slide rule guide of this invention is illustrated in FIG. 1 and
referred to in its entirety by the reference character 10. It
comprises an envelope 11 and a slide 12. Envelope 11 comprises a
panel 13 (FIG. 4) which bears suitable identifying indicia such as
the term "Side A" illustrated at 14, and another panel 15 which is
similarly identified by the term "Side B" at 16 (FIG. 5). Panels 13
and 15 have end edges 17 formed with recesses 18 which facilitate a
user engaging slide 12 for manipulative purposes.
While envelope 11 may be made of any preferred material, it is
preferable that it is of a material which may be coated with a
plastic after the various indicia to be hereinafter described have
been printed thereon. If desirable, the panels may be of paper or
cardboard and covered by a transparent plastic casing.
Referring now more particularly to FIG. 4, the exposed face of side
A is shown as having inscribed thereon a line 19 which defines a
margin 20. Formed in the panel 13 intermediate the ends of margin
20 is a small opening 21. On one side of the opening 21 is
displayed the term "Body Weight" and on the other side is a unit of
weight 22, such as "KG.".
Referring now to FIGS. 2 and 3, slide 12 presents one face 23 which
bears suitable indicia such as "Side A" to identify it; the
opposite face 24 also has indicia such as "Side B" to identify it.
Spaced inwardly from the edge of face 23, which corresponds to the
edge of panel 13, which defines margin 20, are a plurality of FIGS.
25. Each of the figures in the series 25 will approximate the
weight of a patient. Thus, the slide 12 may be moved relative to
envelope 11 to bring the figure in group 25 which most closely
approximates the weight of a patient into position beneath opening
21 in panel 13.
Below margin 20 panel 13 is marked off into four rectangular
sections 26, 27, 28 and 29. Each of these sections displays an
identification of the particular condition of a patient being
treated. Thus, section 26 displays "Normal Maintenance (no
dehydration)" , section 27, "Mod Severe Isotonic Dehydration (Na
130-150)" , section 28, "Mod Severe Hypotonic Dehydration (Na below
130)" , and section 29, "Mod Severe Hypertonic Dehydration (Na
above 150)". Section 26 is formed with a window 30 above which is
the title "Estimated 24 Hr. Therapy". On one side of the window 30
is a group of names of materials, which is identified as 31, and on
the opposite side of window 30 are abbreviations of volumetric
units. These are designated in their entirety as 32. Below window
30 is a second window 33 on one side of which is the term "5%
Glucose Water" and the other side bears the language "ml. in 24
hrs.". This window 33, with the above designatiOns, constitutes
part of a treatment guide including the identification of materials
and quantities thereof. Thus, window 33 and the accompanying
designations constitute a treatment guide.
Section 27 is formed with a window 34, on one side of which is a
group 35 of material identifications, and on the other side, a
group of abbreviations denoting units of volume. This group is
designated 36. The window 34, group 35 and designations 36
constitute a part of the estimated 24 hour therapy with the
remainder being supplied by the fixed determination of potassium
displayed immediately below window 34. Section 27 also is formed
with a window 37 below window 34, with a group 38 of material
identifications on one side, and a group 39 of volumetric unit
designations and time intervals on the other side. Window 37, and
groups 38 and 39, constitute part of a treatment guide, the
remainder of which is supplied by the materials in group 40 and the
indicated number of units 41.
Section 28 is formed with windows 42 and 43. Materials are
identified by a group of designations 44 on one side of window 42
and designations of volumetric units 45 on the other side. Window
42 and designations 44 and 45 are a part of the estimated 24 hour
therapy with the remainder being supplied by the fixed amount of
potassium indicated. The treatment guide is provided by window 43,
the designations of materials on one side at 46 and designations of
volumetric units and time intervals in the group 47 on the other
side. Window 43 and groups 46 and 47 are a part of the treatment
guide which is completed by the fixed designation of materials
indicated therebelow.
Section 29 is formed with windows 48 and 49 which are accompanied
by designations substantially corresponding to those applied to the
windows 42 and 43 of section 28.
Referring now to FIG. 2, face 23 of panel 12 is formed with a group
of FIGS. 50 comprising four rows corresponding to the group 31 of
material identifications of section 26. The figures in the four
rows are arranged in vertical columns and any column will appear in
window 30 when the slide is adjusted to bring the particular figure
of the series 25 opposite opening 21. Face 23 also includes another
row of FIGS. 51, any one of which is adapted to appear in window 33
of section 26. Face 23 of slide 12 displays another group of FIGS.
52, any column of which will appear in window 34 of section 27. It
also displays another group 53 of figures, any column of which will
appear in window 37 of section 27.
Face 23 of slide 12 is provided with another group 54 of figures,
any column of which may appear in window 42 of section 28, another
group 55, any vertical column of which may appear in window 43 of
section 28, still another group 56, any column of which will appear
in window 48 of section 29, and finally, a group 57 of figures, any
column of which will appear in window 49 of section 29.
Referring now to FIG. 5, outer panel 15, which is identified as
"Side B" , is marked off to provide four rectangular sections 58,
59, 60 and 61. Section 58 displays the title "Pyloric Stenosis with
Mild Dehydration" and immediately therebeneath is a small opening
62 accompanied by the designation for body weight. Referring for
the moment more particularly to FIG. 3, face 24 of slide 12
displays a series of FIGS. 63, any one of which is adapted to
appear in opening 62. Below opening 62 is a table for estimated 24
hour therapy, comprising a window 64 with designations of materials
and volumetric units, and a table for treatment guide comprising a
window 65 with designations of materials on one side and volumetric
units and time intervals on the other side. The treatment guide
also includes the designations of fixed quantities of certain
materials. Referring again to FIG. 3, face 24 of slide 12 presents
a group 66 of figures, any column of which may appear in window 64,
and another group 67, any column of which may appear in window
65.
Section 59 displays the title "Pyloric Stenosis with Mod Severe
Dehydration" and immediately therebeneath is a small opening 68
accompanied by the designation "Body Weight" and which cooperates
with a series of numbers 69 which appear on face 24 of slide 12.
Below opening 68 is a table for estimated 24 hr. therapy comprising
a window 70 accompanied by the same designations as window 64 of
section 58 and which cooperates with a group 71 of figures
displayed on face 24 of slide 12. Below window 70 is a table for
treatment guide comprising windows 72 and 73 and accompanying
designations of materials, volumetric units and time intervals.
Cooperating with window 72 is a group 74 of figures on face 24 of
slide 12, while another group of FIGS. 75 cooperates with window
73.
Section 60 bears the title "Severe Diabetic Acidosis and
Dehydration" and beneath this title is a small opening 76 bearing
the designation "Body Weight" and which cooperates with a series of
FIGS. 77 on face 24 of slide 12. Below opening 76 is a window 78
with which is associated the same indicia which is associated with
windows 64 and 70 of sections 58 and 59 respectively and
constituting the table for estimated 24 hour therapy. Cooperating
with window 78 is a group of FIGS. 79 on face 24 of slide 12. Below
the table for estimated 24 hour therapy is a treatment guide
comprising windows 80 and 81. Associated with each of these windows
is a material designation on one side and a designation of
volumetric units and time intervals on the other side. Window 80
cooperates with a group of FIGS. 82 on face 24 of slide 12, while
another row of FIGS. 83 on face 24 cooperates with window 81.
Section 61 displays the title "Renal Shut-Down (Anuria)", below
which is a small opening 84 for body weight designation and which
cooperates with a series of figures 85 on face 24. Immediately
below opening 84 is a table for estimated 24 hour therapy which
includes a window 86 which cooperates with a row of figures 87 on
face 24. Below the table for estimated 24 hour therapy is a table
for treatment guide, including a window 88 which cooperates with a
series of figures 89 on face 24. Panel 13 (FIG. 4) also includes a
lower margin 90 which displays certain directions involving the use
of potassium, while FIG. 5 displays similar directions in a space
91 at the lower right hand corner.
OPERATION
While the manner of using the above described slide rule guide to
intravenous therapy is believed to be obvious from the illustration
of the drawings and description of the elements thereof, it is
briefly described as follows:
The particular condition which is being treated and the weight of
the patient are first ascertained. Such information is usually
available on the patient's chart. The doctor or nurse then turns
the envelope 11 to the proper position in which the title
identifying the condition of the patient comes into view. Slide 12
is now moved to bring the figure in either of the series 25, 63,
69, 77 or 85 into a position in which it is seen through its
respective opening 21, 62, 68, 76 or 84. When this condition is
achieved, the correct amount for each of the materials will be
displayed in the windows of the particular section for that
treatment.
While a preferred specific embodiment is herein disclosed, it is to
be clearly understood that the invention is not to be limited to
the exact construction, devices and indicia illustrated and
described because various modifications of these details may be
provided in putting the invention into practice.
