Description
CLAMP CONNECTING INTRAVENOUS POLE TO MOBILE GURNEY
i f 5 Background of the Invention
1. Field of the Invention
The present invention is broadly concerned with an improved clamping assembly adapted for releasably connecting a mobile, free standing support stand (e.g., a
10 wheeled stand for supporting intravenous fluids and related equipment) to a patient transfer device such as a gurney, bed or wheelchair in such manner as to securely couple the support stand and permit movement of the transfer device and stand in unison by a single attendant.
15 More particularly, the invention concerns such a clamping assembly which preferably includes a clamp body having a pair of spaced apart, opposed jaws cooperatively defining a recessed area for receiving therein the upright standard forming a part of the support stand, with the body also
20 including at least one upstanding, elongated, transversely oriented connector element adapted to mount the clamp body onto the tubular IV pole adapters typically found on gurneys, beds and wheelchairs.
2. Description of the Prior Art
25 One of the most common tasks in a hospital is that of transporting sitting or recumbent patients between wards or to various locations in the hospital. In many cases, such patients are undergoing intravenous fluid therapy, and it is important to transfer the IV assembly
30 along with the patient, in order to eliminate the necessi¬ ty of terminating the IV infusion during transport. Typical IV assemblies include a free standing, wheeled support stand having a castered base with an upright
I standard, the latter having one or more limbs adjacent the 35 upper end thereof.
One response to this problem is to use two attendants for the patient transfer, one to push and guide the patient transfer device (e.g., a gurney, mobile bed or wheelchair) , while the other attendant pushes and guides the IV assembly. Obviously, this is a costly approach, and is extremely inefficient from the standpoint of manpower utilization.
Summary of the Invention The present invention overcomes the problems outlined above, and provides a clamping assembly for permitting releasable interconnection for a mobile trans¬ fer device and a separate mobile support stand, with the connection permitting the stand to be pulled along with the transport device without the need of an extra atten¬ dant.
Broadly speaking, the clamping assembly of the invention includes a clamp body presenting a pair of spaced apart jaws cooperatively defining a recessed area configured for receiving the upright standard of a mobile support stand, with the jaws being equipped with structure for releasably maintaining the standard therein. In addition, the clamp body has at least one, and preferably a pair of, transverse connection elements adapted to be received within a typical upright, tubular IV pole adapt¬ ers found on virtually all patient transfer devices.
In preferred forms, the connection elements are in the form of oppositely extending members each present¬ ing a cylindrical shank portion with a tapered end remote from the clamp body. These elements are moreover config¬ ured with shanks of different relative diameters, so as to permit the clamp assembly to be used with different sizes of tubular adapters. Additionally, one of the jaw sec¬ tions of the clamp body is advantageously configured to present a generally V-shaped segment in plan configura-
tion, and a clamping screw is mounted in the other of the jaw segments; the clamping screw includes an inner clamp¬ ing end which is positioned adjacent the V-shaped segment, so that an upright standard can be securely clamped in place between the clamping screw and V-shaped segment. At the same time, insertion of a connector element within the tubular adapter of a patient transport device allows the coupled support stand to freely pivot during transport to thereby follow the patient transfer device without the need for an attendant.
Brief Description of the Drawings
Figure 1 is a perspective view of the preferred clamping assembly in accordance with the invention; Fig. 2 is a plan view of the clamping assembly, shown as it would appear when used to clamp an upright standard;
Fig. 3 is a side elevational view of the pre¬ ferred clamping assembly; and Fig. 4 is a fragmentary end view illustrating the use of the clamping assembly in releasably securing a conventional wheeled IV support stand to a patient gurney.
Detailed Description of the Preferred Embodiments Turning now to the drawings, and particularly
Figs. 1-3, a clamping assembly 10 in accordance with the invention is illustrated. Broadly speaking, the assembly 10 includes a main body 12 together with a pair of oppo¬ sitely extending, differently configured connector ele- ments 14 and 16. In addition, the body 12 carries a threaded, axially rotatable clamping screw 18.
In more detail, the body 12 is preferably an integral unit and is configured to present a pair of opposed, laterally spaced apart jaws 20, 22 which are interconnected by a central bight section 24 of somewhat
triangular configuration in plan. The jaws 20, 22 and bight section 24 cooperatively define a recessed area 26 as best seen in Fig. 2. The inner defining surface of jaw 20 is substantially planar and is curvilinear as at 28 at the transition between the jaw and the central bight section 24. On the other hand, the inner defining surface of opposed jaw 22 presents a pair of intersecting, gener¬ ally planar surfaces 30, 32 which cooperatively present a generally V-shaped segment 34 at the inboard region of jaw 22.
Connection element 14 is located at the apex of the bight section 24 and presents a cylindrical shank portion 36 as well as a tapered outermost end 38 remote from the body 12. Likewise, it will be observed that the connection element 16 is mounted at the apex of the section 24, and includes a cylindrical shank portion 40 as well as a tapered outer end 42. As best illustrated in Fig. 3, the respective shank portions 36, 40 forming a part of the elements 14, 16 extend in opposite directions from the opposed upper and lower surfaces of the body 12.
Moreover, these shank portions are of different diameters, i.e, the shank portion 36 has a smaller diameter than that of the opposed shank portion 40.
Clamping screw 18 is threadably received by an appropriately threaded aperture 44 provided in jaw 20. As best illustrated in Fig. 2, the screw 18 includes an elongated threaded shank 46 with a resilient, cup-like cap 48 secured on the inner end thereof within recessed area 26. It will also be noted that the longitudinal axis of the shank 46 is substantially aligned with the apex of V- shaped segment 34, and is of a length to extend to a position very close to surfaces 30, 32. The outermost end of the shank 46 located outside of the recessed area 26 is equipped with a handle 50 allowing easy manipulation of the clamping screw.

Fig. 4 illustrates the use of clamping assembly 10 for connecting a free standing IV pole unit 52 to a conventional patient gurney 54. The pole unit 52 includes a relatively wide base 56 provided with caster wheels 58, as well as an elongated, upstanding, two-piece telescopi- cally interfitted standard 60. Although not shown, those skilled in the art will appreciate that appropriate limbs or other structure is provided at the upper end of the standard 60 for supporting supplies of IV liquid or other equipment. Gurney 54 includes a frame assembly 62 as well as a patient bed 64. In addition, gurneys of this type are conventionally provided with upstanding, upwardly opening tubular sections adjacent the corners thereof, such as the section 66 illustrated. In the use of clamping assembly 10, one of the connection elements 14 or 16 is inserted into a convenient tubular section 66 in such manner as to allow free pivot¬ ing of the clamping assembly therein. At this point, the pole unit 52 is wheeled to a position adjacent the clamp- ing assembly, and is moved so that the standard 60 thereof is positioned within recessed area 26, and specifically adjacent the planar surfaces 30, 32. In order to complete the connection, it is only necessary to manipulate handle 50 in order to tighten the inner end of the clamping screw against the standard 60, thereby firmly clamping the latter between the clamping screw and the V-shaped segment 34. In this orientation, the gurney 54 can be convention¬ ally moved and guided, with the pole unit 52 being secure¬ ly attached and following the gurney, all without the need for an extra attendant.
It will be appreciated in this respect that the interfit between the connection element 14 or 16 and the tubular section 66 allows the pole unit 52 to pivot about the axis of the connection element. Thus, the coupled pole unit can easily negotiate turns with the gurney 54,
while remaining completely stable. Use of differently sized connection elements 14, 16 allows the clamping assembly to be universally employed on virtually all commonly used patient transport devices, such as gurneys, wheelchairs or hospital beds.
