CATHETER STORAGE RACK
Abstract
This invention is directed to a catheter storage rack that
comprises a rigid supporting plate upon which a plurality of spaced
tubular guides are mounted and arranged along the locus of the
desired configuration of a catheter to be supported on the rack. A
curved tubular guide is provided to retain and support the curved
distal end of the catheter in its naturally curved
configuration.

Claims
We claim:
1. A sterilizing and storage rack for an elongated flexible
cardiovascular catheter having a curved distal tip comprising a
rigid supporting plate, a plurality of tubular guides being spaced
along the locus of the desired catheter configuration, and a final
tubular guide spaced along said locus at the distal end of said
catheter and curved to support said curved distal tip.
2. The catheter storage rack of claim 1 in which said locus is a
spiral.
3. The catheter storage rack of claim 1 in which said locus is a
straight line.
Description
THE INVENTION
This invention relates generally to new and useful improvements in
storage devices and particularly seeks to provide a novel plate or
rack for the care and storage of cardio-vascular and other types of
catheters.
It is generally recommended that catheters be stored in coils of
about 8 inches diameter so that they will readily fit in a
sterilizer prior to use. Mostly, the catheters simply are wound in
a loose coil and wrapped in surgical cloth or papers and stored.
Such storage does not protect the catheter and does not maintain
the curved distal tip in its proper state of curvature.
However, a storage rack constructed in accordance with this
invention firmly retains a catheter and its curved tip in the
desired coil and can be bodily inserted in a sterilizer while still
carrying the catheter.
Therefore, an object of this invention is to provide a storage rack
or plate for catheters that includes a supporting plate upon which
is mounted a plurality of angularly spaced tubular guides arranged
along the locus of the catheter coil to be formed.
Another object of this invention is to provide a rack of the
character stated in which the curved distal tip of the catheter is
supported within a tubular guide that is curved to conform to the
normal curvature of the tip.
Another object of this invention is to provide a rack of the
character stated that is fabricated from materials that will
withstand sterilization .
With these and other objects, the nature of which will be apparent,
the invention will be more fully understood by reference to the
drawings, the accompanying detailed description and the appended
claims.
In the drawings:
FIG. 1 is a top plan view of a catheter storage rack constructed in
accordance with this invention; and
FIG. 2 is a fragmentary transverse section taken along line 2--2 of
FIG. 1.
Referring to the drawings in detail the invention, as illustrated,
is embodied in a catheter storage rack and includes a rigid
rectangular supporting plate 5 that may be formed from colored
glass or any other suitable material that is capable of
withstanding sterilization. A colored plate is preferred in order
to provide visual contrast when a catheter is to be mounted
thereon.
A short tubular guide 6 is affixed, as by cement, to the upper face
of the plate 5 adjacent one corner thereof and a plurality of
angularly spaced arcuate tubular guides 7 are similarly affixed
thereto along the locus of the catheter coil to be formed. A tip
guide 8 is secured to the plate 5 at the position of the distal tip
of the catheter and is curved to conform to the shape of the
catheter tip so that the tip will retain and be supported in its
natural curve.
In use, the distal end of a catheter 9 is first lead through the
guide 6 and then through successive guides 7 and into the tip guide
8 whereby to form the catheter into a coil and support same in that
configuration.
The storage rack of this invention may also be used in any instance
where a catheter is to be stored in a straight or uncoiled
condition with its curved distal tip protected. In this event the
plate 5 would be elongated and the guide 6 would be oriented in the
long direction thereof with the guides 7 (now straight instead of
arcuate) spaced along the locus of a straight line coaxial with the
guide 6 and with the curved tip guide 8 at the distal end
position.
