Various aspects of at least one embodiment are discussed below with reference to the accompanying figures. The figures are provided for the purposes of illustration and explanation and are not intended as a definition of the limits of the invention. In the figures:
In accordance with one or more embodiments, electrical cords and other cables may be enhanced to facilitate folding and storage thereof in a manner that is consistent, organized and leaves them ready and properly arranged for rapid, reliable deployment. Replacement of cables associated with various equipment, as well as readiness of an associated device for subsequent use is improved, along with the overall appearance and presentation of the cable to a user. Easy and efficient folding of a cable into a prescribed form may be enabled. The folding prescription may not compromise the flexibility of the cord, nor the extension of the cord to its full length. The prescribed folding arrangement or shape may enable the cord and any associated connectors to be provided in a known relationship. The folding arrangement may correspond to an intended containment device to facilitate cable storage. In this way, a prescribed folding may help to achieve stowage of the cords and cables in designated places, as well as facilitate predictable deployment therefrom substantially without tangling, such as for reliable therapy in an emergency situation.
In accordance with one or more embodiments, a conduit, cord or cable may be associated with equipment in various industries including the electronics, consumer products and medical device sectors. Conduits, cords and cables may vary in size, length, geometry, materials and types depending on adaption for intended use. Conduits, cords and cables may transport signals, liquids, gases such as for pneumatics, or other matter. In at least some embodiments, an electrical cord is disclosed. Various types of electrical cords include coaxial, multicore, ribbon, shielded, single and twisted. In some non-limiting embodiments, a cable may be a line cord or patient therapy cable such as, but not limited to ECG, ETCO2 and SPO2 patient cables, including those commercially available from Zoll Medical Corporation of Chelmsford, Mass., the assignee of the present application. For example, a cord may be a medical cable such as those disclosed in U.S. Pat. No. 7,351,912 to Lund et al. which is hereby incorporated herein by reference in its entirety for all purposes. In other embodiments, an electrical cord may be a power cord.
In accordance with one or more embodiments, an electrical cord may include a first end and a second end. A first connector may be positioned at a first end and a second connector may be positioned at the second end. The connectors may facilitate attachment of the electrical cord to a power source or may be appliance-side connectors to interface equipment which the cord is intended to service, including medical devices or components thereof such as defibrillators electrodes. The electrical cord may generally contain one or more conductors, such as fibers or wires, electrically connecting the first connector to the second connector and providing electrical communication therebetween. The construction of the conductor, such as whether it is solid core or fine stranded may impact the flexibility of the electrical cable. The cord or cable may also include other components commonly known to those in the art such as insulation, fillers, sheaths and spacers. Furthermore, a casing or jacket as commonly known in the art may enclose the wires for protection of both its components as well as a user. Various factors including working voltage, current-carrying capacity and various environmental conditions may impact design of the cable.
In accordance with one or more embodiments, an electrical cord or other cable may include one or more segments which are enhanced to facilitate folding. In some non-limiting embodiments, such segments may discourage a user from bending the cord or cable at the enhanced segments. One or more further segments may be substantially unenhanced. In at least some non-limiting embodiments, one or more enhanced segments may be less flexible than one or more further segments. The nature and number of the enhanced and unenhanced segments may predispose a cord to fold in specific areas, encouraging a user to fold the cord in a predefined arrangement. A prescribed folding arrangement may facilitate storage and deployment of the cord in a predictable manner. In some non-limiting embodiments, the prescribed folding arrangement may involve an accordion fold. A predetermined folding arrangement may also be characterized by circular, triangular, rectangular or other desired geometry. Other arrangements and shapes may be implemented depending on an intended application. In some embodiments, the folding arrangement may correspond to a storage device for the cable, cord or conduit or may correspond to facilitate an intended use thereof. The predetermined folding arrangement may be designed to facilitate location of and access to one or more connectors at ends of the cable. The predetermined folding arrangement may also maintain a cable in an orderly manner so as to facilitate deployment and storage thereof. When not in use, the cord or cable may be folded for storage in a manner that will facilitate proper fit in a designated storage device.
The number, positioning, arrangement and size of the substantially enhanced and substantially unenhanced sections may depend on various factors including a desired predefined folding arrangement, storage limitations, desired flexibility, desired durability, geometry of associated storage devices, geometry of associated equipment serviced by the cord, frequency and environment of cord deployment and various characteristics of the cord including its dimensions and materials. In some non-limiting embodiments, enhanced and unenhanced sections may be alternated along a length of the cable. In certain embodiments, a cord may include one, two, three or more enhanced sections as well as one, two, three or more unenhanced sections.
In accordance with one or more embodiments, one or more segments of the electrical cord or cable may be enhanced through stiffening. In some embodiments, certain sections of the cord may be stiffened to prevent folding in those sections while predisposing the cord to fold in one or more further sections. In accordance with one or more embodiments, local stiffening can be accomplished in various ways known to those in the art.
In at least some embodiments, an effective thickness of the sleeve or jacket may be manipulated in one or more enhanced segments to render those segments substantially stiffened in comparison to one or more unenhanced segments. In some embodiments, for example, the cord may be over-molded at one or more enhanced segments. In other embodiments, localized co-extrusion of excess material on the cord jacket may be performed at the enhanced segments. In still further embodiments, internal stiffening members may be added at enhanced segments. In at least one embodiment, attachable stiffening agents may be implemented at one or more enhanced segments. In still other embodiments, heat-shrinkable sleeves may be applied at the one or more enhanced segments.
In other embodiments, materials or material properties may be manipulated to achieve a desired arrangement of enhanced and unenhanced segments. In some embodiments, a cord jacket may be made of a first formulation at the enhanced segments, and of a second formulation at the unenhanced segments. For example, the enhanced and unenhanced segments may be made of different polymers, elastomers or rubbers. Alternatively, the same material may be used in both the enhanced and unenhanced segments, but a property of the material may be altered between them, such as through compounding. For example, one may vary the composition of a particular material (e.g. polyurethane) in order to change its durometer or shore hardness between the enhanced segments and unenhanced segments. This may allow for the same material (but with varying composition) to be used for the entire cord, thus simplifying manufacture.
One or more further segments may be substantially unenhanced to facilitate creation of a prescribed folding arrangement. Unenhanced or unstiffened segments may allow the cord to remain substantially flexible overall as well as to maintain the overall effective length of the cord. The desired degree of enhancement, such as stiffness, of the enhanced segments is subjective and may vary depending on the intended use of the cord. The ratio of the enhanced and unenhanced segments along a length of the cord may also vary depending on intended use.
In accordance with one or more embodiments, a conduit, cable or cord may include indicia to facilitate its deployment, use or storage. In some embodiments, such indicia may correspond to accompanying instructions directed to a user. Indicia may include coding based on color, symbol, text or other system. In at least one embodiment, indicia may facilitate storage of a cable such that one or more connectors positioned at ends of the cable may be easily located and accessed for use.
In accordance with one or more embodiments, a conduit, cable or cord may include further features to facilitate its use and storage, such as a tether or like structure or system intended to constrain at least a portion of its length or otherwise adjust an effective length of free conduit, cable or cord. For example, in some embodiments a portion of a conduit, cable or cord may be constrained, folded or otherwise stored while a further portion remains extended or otherwise available for manipulation and use.
In accordance with one or more embodiments, a medical system may include a medical device and an electrical cable. The medical system may further include a cable retainer. For example, a medical system may be one such as that disclosed in U.S. Pat. No. 7,530,840 to Lund et al. which is hereby incorporated herein by reference in its entirety for all purposes.
In accordance with one or more embodiments, a cord management system may be provided to facilitate storage of a cord in a known and accessible place. A management system may include an electrical cord and a cord storage unit or containment vessel. The cord storage unit may be constructed and arranged to receive the cord in a prescribed folding arrangement. The electrical cord may be removably receivable by the cable containment vessel. The predetermined folding arrangement may be correlated with at least one dimension of the containment vessel. For example,
Cable management may be facilitated by providing an electrical cable having at least one section along its length predisposed to fold the electrical cable in a prescribed folding arrangement and providing a cord storage vessel compatible with the prescribed electrical cable folding arrangement.
An electrical cord may be retrofitted in accordance with one or more embodiments to facilitate folding, storage and deployment thereof. For example, enhancing features, such as stiffening members, may be applied to one or more segments while one or more further segments may remain substantially unenhanced to promote folding in a prescribed manner.
