Description

June 26, 1962 H. w. PAYTON 3,040,749
UMBILICAL CORD CLAMP Filed April 7, 1958 u] L /6 5 13 2 l2 6 I 5 m w. W2
I BY F'L g El Wu tates trite This invention relates to clamp apparatus and is more particularly directed to an umbilical cord clamp.
The various devices previously employed as umbilical cord clamps have proven unsatisfactory in many respects. In most cases'the prior art clamp devices are too costly and too involved as to application. In many instances they are so formed that they may be inadvertently opened once they are applied. This is highly and fundamentally undesirable for medical applications. As a matter of fact, the present practice is to both clamp and tie the umbilical cord to make certain that no accidents occur.
This invention provides an expendable and disposable umbilical cord clamp which is simple and very economical to fabricate. Moreover, the clamp is completely safe for medical purposes. Once it is closed it cannot be snapped opened and its nature is such that there is no trauma to the skin of the belly in use.
A primary object of the invention is to provide improvements in umbilical cord clamps whereby such devices may not only be economically manufactured but will be more efiicient and satisfactory in use and adaptable to a wide variety of applications.
Another object of the invention is to provide an umbilical cord clamp which cannot be snapped opened, once it is closed in use.
A further object of the invention is to provide improved clamp aparatus articularly applicable as a medical clamp which produces no trauma to adjacent surfaces in use.
An additional object of the invention is to provide an expendable and disposable umbilical cord clamp which eliminates cleansing and sterilization procedures.
A further object of the invention is to provide an improved umbilical cord clamp which is self adjusting in use.
Another object of the invention is to provide a device particularly applicable for'use as an umbilical cord clamp possessing the advantageous structural features, the inherent meritorious characteristics and the mode of operation herein described.
A further object of the invention is to provide an umbilical cord clamp possessing the advantageous structural features, the inherent meritorius characteristics and the mode of operation herein mentioned.
With the above and other incidental objects in view as will more fully appear in the specification, the invention intended to be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation as hereinafter described or illustrated in the accompanying drawings, or their equivalents.
Referring to the accompanying drawing wherein is shown one but obviously not necessarily the only form of embodiment of the invention,
FIG. 1 is a side view of an embodiment of the invention showing the clarnp in a closed condition;
FIG. 2 shows the clamp of FIG. 1 in an open condition;
FIG. 3 is atop View of the device as shown in FIG. 1;
FIG. 4 is a sectional view taken on line 44 of FIG. 3; and
FIG. 5 is a view similar to FIGJI but showing the nature of the clamp as applied to an umbilical cord.
Like parts are indicated by similar characters of reference throughout the several views.
right angles from the face 6. The flange 7 has a hooked extremity 8 projecting inwardly to the bar 1 and in the direction of the ears 5.
The part 2 consists ofa generally rectangular bar 11 having spaced projections 9 on one face 10. A rib 12.
formed integral with the bar 11 projects centrally and longitudinally from its opposite face 13 extending from a point short of one end 14 to project beyond and from its other end 15.
The cars 5 on end 4 of the bard have oppositely aligned apertures. The portion of the rib 12 which projects beyond the end 15 of the bar 1 has opposite integral pin-like projections 16 laterally thereof. The projecting end portion of the rib 12 is disposed between the ears 5, the resilient nature of the plastic material enabling the spreading of the ears so the pin-like projections may be engaged in the apertures therein. The parts 1 and 2 are thus assembled in pivotal relation.
The connection of the parts 1 and 2 as shown is such to dispose the rib 12 outwardly of the clamp assembly as the bar 11 is pivoted to nest to the bar 1 between the flange 7 and the ears 5 to either end. This disposes the face projections 9 on the bar 11 in abutment with the face 6 of the bar 1.
The face 13 of the bar 11 adjacent its free end 14 is provided with an undercut recess 17 in alignment with the rib 12. The recess 17 is adapted to accommodate the hook 8 on the flange 7.
The advantages and application of the invention em bodiment are best understood from its preferred use. The clamp assembly is applied about an umbilical cord C as seen in FIG. 5 of the drawings, the cord C being received substantially centrally of part 1 to abut the face 6 between the flange 7 and ears 5. The part 2 is then pivoted to nest in the part 1 over the umbilical cord, the flange 7 being flexed to allow the end 14 of the bar 11 to seat inwardly of the hook 8 which is then engaged over the outer face of the bar 11 and into the recess 17 therein. The angle of the extremity of the hook 8 is such as to interlock in the undercut recess of the bar 11. The cord C is pressured in the process to spread laterally and be compressed over the projections 9 on the inner face of the bar 11.
The clamp assembly is thus locked about and to the umbilical cord and due to the initial substance of the cord the bar 1 is initially bowed by the cord as it is locked. The greater the pressure effect on the bar 1, the tighter is the engagement of the hook 8 in. the undercut recess 17 of the bar 11, in a manner believed obvious. The clamp unit is self adjusting in that its resilient material will adjust to the shrinking of the cord due to the internal drying procedure. There is no trauma developed in the process.
An umbilical cord clamp so simply fabricated and assembled is so cheap as to be readily disposable and expendable. It eliminates the usual sterilization and cleansing procedures necessary in the use of present-types of umbilical cord clamps and ties. The present invention distinguishes, moreover, in that it is permanent and positive in nature and cannot be inadvertently snapped open once it has been applied to the cord. The inherent locking features of the clamp assembly and its self adjusting characteristics are invaluable for medical application. In
the preferred use of the invention there is no pull on the umbilical cord in any sense.
7 Patented June 26, 1962 From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.
While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise but one of several modes of putting the invention into efiect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
