CLAMPING DEVICE Filed Feb. 25. 1959 INVENTOR i/a/w/mw 60/01/666 BY JM%% ATTORNEYS United States Patent Ofiiice 3,080,867 Patented Mar. 12, 1963 3,080,867 CLAMPING DEVICE Maximilian Eichinger, Maxingstrasse 62, Vienna XIII/ 89, Austria Filed Feb. 25, 1959, Ser. No. 795,459 Claims priority, application Austria May 22, 1958 6 Claims. (Cl. 128--346) This invention relates to a clamping device and is more particularly related to a clinical clamping device with flexible lines, such as tourniquet tube, and a mechanical clamp.
In the administration of intravenous injections or taking of blood samples, for example from the arm vein of humans, it is v-irtuallynecessary to provoke a vascular engorgement of the vein to facilitate insertion of a tubular needle. 'Ihi-s engorgement is achieved by tying the limb with a strap or the like. When using a flexible tube for [tying aphysi cian generally-fixes the tube ends in a half knot between the limb and tube to prevent slackening of the tension. tient. I,
Flexible tube clamps]j have been previously proposed, as shown in U.S. Patents 1,532,229 and No. 1,387,- 358, as well as in German 'PatentNo'. 645,126. Such This can sometimes Ibepainful for, the pa- :previously known clampin'gflde'vices incorporate, e.g., a
pipe in which the flexible-tube is inserted and clamped by a sliding boltglatera lly shiftable in oblique slots, or 'the flexible tube isjfixed by a'comparatively intricate device having many components. Compared to the pre VlOllSlY known devices the subject clamping device of "this invention is remarkable for its particularly simple construction and the fact that clamping and adjusting may be accomplished in a particularly easy manner.
The proposed clinical clamping device according to the present invention permits rapid and positive tightening and fixing of a flexible elongated material arranged to form a loop, especially for tying a limb -by means of a flexible tube for administration of intravenous injections and the like, without causing pain to the patient. It provides for similar rapid positive release of the clamp. The f. cla'mpi is simple and foolproof and can be completely disassembled for sterilization, merely by slipping it off the flexible loop material.
' Accordingly, a primary "object of this invention resides in providing af'noveltourniquet with a flexible loop and a simple sliding mechanical clamp device with provision for rapid easy release of clamping action.
A further object resides in the provision of a loop of I flexible tubular material and a simple novel clamp device vention will become apparent from the following detailed description, discussion and the appended claims taken in conjunction with the accompanying drawings showing a preferred structure and embodiment, in which:
FIGURE 1 is a perspective view illustrating a flexible tubular tourniquet loop the ends of which are clamped in a small releasable clamp, as a preferred example of this invention; V FIGURE 2 is a side view of the clamping device shown in FIGURE 1 with the plungers disposed in .a position enabling free sliding of the loop ends which are shown in phantom line'for convenience of illustrating clamp component details.
FIGURE 3 is a section view taken on line 33 of FIGURE 2 illustrating the interior details of the clamping device disposed in release position;
FIGURE 4 is a view simlar to FIGURE 2 but illustrating the clamp device in its clamping position; and
FIGURE 5 is a perspective view illustrating the disassembled components of the clamp device enabled by removing the tourniquet loop end-s.
In general, the invention is exemplified by a clinical tourniquet 8 (FIGURE 1) consisting of a flexible tube 10 arranged in a loop with its ends 12 projected through a clamp device 14. Briefly, the clamping device 14 consists of a tubular sleeve member with two plungers disposed for sliding within the sleeve member between the plungers. The sleeve member and the two plungers are provided with transvense bores which are in alignment when the spring is completely compressed (the innermost position of the plungers, FIGURES 2 and 3).
The ends 12 of the flexible tube 10, which can be any of many elongated flexible materials and not necessarily tubular, arranged to form a loop, project through respective aligned cross bores in the mechanical clamp and prevent the plungers from being displaced out of the sleeve.
The manipulation of the clamping device according to the invention can be understood by viewing FIGURES 3 and 4, FIGURE 3 showing the plungers in the innermost position, which is accomplished by squeezing the plungers with thumb and forefinger, where clamping action is prevented and FIGURE 4 showing the plungers disposed by spring bias in an outer clamping position.
In the specific illustrated example, the clamp device 14 consists of a cylindrical sleeve 16 which has two spaced apart transverse bores 18 and 20 symmetrically arranged in relation to the center of sleeve 16. Two free sliding cylindrical plungers 22 are arranged symmetrically within opposite ends of sleeve 16 and each plunger 22 is provided with a transverse bore 24 having diametral dimensions similar to the sleeve cross bores 18 and 20. The bores 18 and 20 of sleeve 16 are in alignment with associated bores 24 of plungers 22 when the faces 26 of the plungers are substantially flush with the ends of the sleeve 16. In this position a cavity or chamber 28 is provided within the sleeve 16 between the plungers 22 and disposed in chamber 28, and engaging both plungers 22, is a substantially completely compressed helical spring 30. In this compressed position of the helical spring 30 and inner positions of the plungens 22, obtained 'by compression between thumb and forefinger of one hand, the ends 12 of the flexible, elongated material 8, the tourniquet tube, can be easily projected through the two sets of common align-ed transverse bores of sleeve 16 and plunger 22, and/or the clamping device 14 may be freely shifted on the flexible tube 8, to decrease or enlarge the size of loop 10. When the desired position is obtained (e.g., the flexible tube fits tightly around the limb to be tied) clamping of the tube 8 is achieved by releasing the plungers 22 which were pressed together. This clamping position may be maintained for an optional time. Clamping is immediately released by pressing the plungers 22 together between thumb and forefinger, whereupon the clamping device again may be freely shifted on the tube. Note, release is dependent only upon pressure on the plungers 22 and not upon momentary further tightening of the loop, as in some previously proposed devices.
An auxiliary ringlet 32 of soft spongy material, e.g., foam rubber, if desired, can be placed around sleeve 16 between cross bores 18 and 2a to prevent the hard surface of the clarnp from hearing directly on the limb to which the tourniquet is applied, or the ringlet can be used to apply pressure on a pressure point.
The sleeve and plunger components of the clamp 14 can be made from any desirable hard rigid material, such as an aluminuli alloy, stainless steel, Bakelite or many of the new plastic compounds. The sleeves and plungers need not be cylindrical, e.g., they could be square or of some other polygonal cross-section, or the outer surface 7 of the sleeve could be made of an infinite variety of crosssection shapes with a cylindrical bore and cylindrical plungers.
The foregoing description discloses a new tourniquet and clamp combination useful in many clinical applications. In veterinary applications it has been used for castration. The clamp device itself is simple, rugged and easily manipulated for positional adjustment to and from clamping position.
The invention may be embodied in other specific forms Without departing from the spirit or essential characteristics thereof. Thepresent embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
