Protective guard for a hypodermic needle
Abstract
A protective guard is provided which may be taped, or otherwise
attached, to the arm or other part of a patient's body to provide a
cover or guard for a hypodermic needle during an intravenous
injection, or the like. The protective guard is formed of a
flexible plastic material, and it is configured to assume a variety
of shapes to adapt itself to different inclinations of the
hypodermic needle and to different parts of the body in which the
needle may be injected.

Claims
What is claimed is:
1. A universal guard for a hypodermic needle, and the like,
constructed to fit different parts of the body of a patient into
which the needle may be inserted, and which is adapted to be taped
to the body and to be bent to a variety of configurations to form a
protective shield for the needle without interfering with the
position in which the needle is inserted into the body, said guard
including: an elongated open-ended channel-like body portion formed
of flexible plastic material adapted to be mounted in an inverted
position over the needle inserted into the body of the patient to
form an enclosure for the needle, said body portion having an
intermediate notch therein on each side thereof to permit said body
portion to be bent about an intermediate axis, a first pair of
deformable integral tabs mounted at one end of the channel-like
body portion, a second pair of deformable integral tabs mounted at
the other end of the channel-like body portion, and a further pair
of elongated mounting tabs integral with and extending outwardly
from the tabs of the second pair, said tabs permitting the body
portion to be set to different heights and inclinations.
2. The universal guard defined in claim 1, in which said elongated
body portion tapers from one end to the other.
Description
BACKGROUND OF THE INVENTION
Intravenous feeding is a technique by which nourishment is
introduced directly into a vein of the patient. The usual prior art
apparatus for intravenous feeding comprises a bottle of intravenous
solution which is inverted over a drip chamber, and which includes
a tube extending from the bottom of the drip chamber to a
hypodermic needle which is inserted into the vein of the
patient.
Problems have been encountered in the past in assuring that the
needle will not inadvertently be knocked out of the vein during the
intravenous feeding operation. The purpose of the present invention
is to provide a protective guard which may be made of plastic, or
other appropriate material, and which may be disposable. The
protective guard of the invention forms an open-ended enclosure for
the hypodermic needle, and it is intended to be taped over the
needle during the insertion so as to shield and protect the needle
without interfering with the needle in any way, or affecting the
inclination with which it is inserted into the vein of the
patient.
The protective guard of the invention is constructed so that it may
be set to different heights and inclinations to accommodate
different needle inclinations, and it also may be set to a variety
of configurations to adapt itself to the different parts of the
patient's body in which the needle may be inserted.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a somewhat schematic representation of an intravenous
feeding apparatus in which a hypodermic needle is inserted into a
vein in the arm of a patient, and showing the manner in which the
protective guard of the invention is taped to the arm to protect
the needle;
FIG. 2 is a perspective representation of one embodiment of the
protective of the invention; and
FIGS. 3 and 4 show a variety of configurations which the protective
guard may assume, so as to adapt it to be fitted to various parts
of the body in which the needle is inserted, and to accommodate
various needle inclinations.
DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
The apparatus shown in FIG. 1 includes, for example, a bottle of
intravenous solution designated 10 which is suspended in an
appropriate bracket 12 which, in turn, is mounted on a stand 14.
The intravenous solution from the bottle 10 passes through a drip
chamber (not shown) and through a tube 16 to a hypodermic needle 18
which is injected into the vein of a patient.
In the illustration of FIG. 1, the hypodermic needle 18 is shown as
inserted into a vein in the arm of the patient. However, in
accordance with usual medical practice, the needle may be inserted
into other parts of the body. As explained above, an important
feature of the structure of the present invention, is that it may
be set to various configurations to accommodate the different parts
of the body in which the needle 18 may be injected, and to
different inclinations of the needle 18.
As shown particularly in FIG. 2, the protective guard of the
invention, as designated 20, includes an elongated body having a
concave-shaped cross-section and which, in turn, defines an
open-ended closure for the hypodermic needle 18. The guard is
formed, preferably, of a flexible plastic material, and it may be
disposable.
In the particular embodiment illustrated in the drawing, the guard
is provided with integral tabs 22 and 24 at the forward end, and
with integral tabs 26 and 28 at the rear end. The guard is also
provided with a central notch 30 at each side which permits the
body to be turned about an intermediate transverse axis. Further
elongated mounting tabs 32 and 34 extend longitudinally from the
respective tabs 22 and 24.
As shown in FIG. 1, the protective guard 20 may be positioned over
the needle 18 with the tabs 22, 24, 26 and 28 turned outwardly, and
with the mounting tabs 32 and 34 extending around the arm of the
patient. The guard may be securely taped in place by appropriate
adhesive tape 21. When in place, the guard forms a protective
enclosure for the hypodermic needle 18, but does not interfere with
the needle in any way, so that its injection into the vein of the
patient is in no way affected.
As shown in FIG. 3, the protective guard may have a configuration
A, which is the configuration of FIGS. 1 and 2, in which its body
section is straight, and the tabs are flat. The representation at B
in FIG. 3 is similar to that of A, but in which the body section is
bent in one direction; whereas in the representation C the body
section is bent in the opposite direction. In the representation D
of FIG. 3, the tabs 22 and 24 are bent down from the body section,
with the mounting tabs 32 and 34 being turned flat at right angles
to the tabs 22 and 24. In the representation E of FIG. 3 the tabs
26 and 28 are turned down, and the tabs 22, 32, 24 and 34 are
turned flat. Further configurations are shown in the
representations F-K of FIG. 4.
It will be appreciated, therefore, that the guard of FIG. 2 may be
bent to a variety of configurations, such as shown in
representations A-K of FIG. 3, and additional combinations thereof,
to accommodate different inclinations of the injected hypodermic
needle so as to have universal application and to fit different
parts of the body in which the needle may be inserted. In each
instance, the guard is taped securely to the patient, so as to form
a protective shield for the needle without in any way interfering
with the original position in which the needle was inserted into
the patient.
The guard of the invention is inexpensive, and may be produced by
mass production techniques, so as to be disposable. As described,
the guard has a general form, or shape, which is constructed so
that the guard may have universal bending and forming capabilities
so that it may be fitted to any part of the body to achieve its
intended purpose.
It will be understood that although a particular embodiment of the
invention has been shown and described, modifications may be made.
It is intended in the claims to cover the modifications which come
within the true spirit and scope of the invention.
