Abstract

A medical cable system includes a plurality of device cables (24) having distal ends adapted to be electrically connected to medical sensing devices (22) that, in turn, are attached to a patient. A main cable (28) has a first end electrically connected to proximal ends of the plurality of device cables (24), and a second end adapted to be connected to a monitor (26). A cable furcation block supports (46) the proximal ends of the device cables (24) and the first end of the main cable (28) with respect to a pole clamp (36). The cable furcation block (46) may be releasably coupled to the mount (36).

a furcation block supporting the proximal ends of the plurality of device cables and the first end of the main cable, the proximal ends of the plurality of the device cables and the first end of the main cable being permanently joined together in the furcation block, the permanent connection between the device cables and the main cable eliminating the need for electrical connectors connecting the device cables to the main cable, thereby improving the electrical reliability of signals being conducted by the device cables and the main cable while reducing size and cost of the furcation block;

a mount adapted to be attached to a structure;

a first coupling element on the mount; and

a cooperative coupling element on the furcation block coupled manually and without tools with the first coupling element to releasably support the furcation block on the mount, thereby permitting the furcation block to be manually and without tools quickly removed from the mount.

2. The medical system of claim 1 wherein one of the cooperative coupling elements is a slot in the mount having a shape corresponding to a shape of the furcation block to permit the furcation block to slide in the slot and be supported by the mount.

3. The medical cable system of claim 2 wherein the slot in the mount is a generally T-shaped slot and a cross-sectional profile of the furcation block is a generally T-shaped profile.

4. The medical cable system of claim 2 wherein the furcation block has an outer surface made of a pliable material providing a relatively high friction interface between the furcation block and the slot to more firmly secure the first furcation block to the mount.

5. The medical cable system of claim 1 wherein the distal ends of the plurality of device cables terminate into electrical connectors and the mount further includes a plurality of storage compartments receiving and temporarily supporting the connectors on the mount whereby placing the electrical connectors on the distal end of the device cables in the storage compartments protects the electrical connectors from contamination and damage.

6. The medical cable system of claim 5 wherein the plurality of storage compartments is a plurality of cavities formed in one end of the mount.

7. The medical cable system of claim 6 wherein the plurality of cavities are open through a lower side of the mount.

8. The medical cable system of claim 7 wherein the plurality of cavities are covered by an upper side of the mount.

9. The medical cable system of claim 1 further comprising:

a plurality of monitor cables, each of the monitor cables having a distal end adapted to be connected to the monitor and a proximal end connected to the second end of the main cable; and

a second furcation block supporting the proximal ends of the monitor cables and the second end of the main cable.

10. A medical cable system comprising:

a plurality of device cables, each having a distal end adapted to be in electrical communication with a medical sensing device and a proximal end;

a first coupling element on the mount; and

a cooperative coupling element on the furcation block coupled manually and without tools with the first coupling element to releasably support the furcation block on the mount, thereby permitting the furcation block to be manually and without tools quickly removed from the mount,

11. A medical cable system providing a plurality of device cables connected to a plurality of medical sensors for measuring physical conditions of a patient, the medical cable system further providing a single cable for electrically connecting the plurality of device cables with a monitor providing a display of the physical conditions being monitored, the medical cable system further comprising:
