Description

Technical Field

[0001] The utility model relates to the technical field of cables, and more particularly to a pressure-resistant cable for medical equipment. Background Art

[0002] A cable is a device that transmits electrical energy or signals. It typically consists of several or several groups of wires, with internal current flowing and external insulation. Cables can be used to transmit electrical (magnetic) energy and information, enabling electromagnetic energy conversion.

[0003] At present, in the medical field, medical equipment usually uses cables to transmit electrical energy or signals. In order to facilitate patients' use, some medical equipment often needs to be moved frequently, and the cables need to be moved together every time they are moved. Since the cables usually have a certain length, they are prone to being stepped on when moving with the medical equipment and when used after moving. Most existing medical equipment cables are usually cylindrical, with core wires evenly distributed inside and a compact internal structure. The internal core wires are easily damaged when stepped on or squeezed by external forces at any position. For this reason, the utility model proposes a pressure-resistant cable for medical equipment. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In response to the problems existing in the prior art, the purpose of the present utility model is to provide a pressure-resistant cable for medical equipment, aiming to solve the problem that most medical equipment cables in the prior art are usually cylindrical, with core wires evenly distributed inside and a compact internal structure, and the internal core wires are easily damaged when stepped on or squeezed by external forces at any position.

[0006] 2. Technical solution

[0007] In order to solve the above problems, the present invention adopts the following technical solutions:

[0008] A pressure-resistant cable for medical equipment includes an outer sheath, an inner sheath fixedly connected to the outer sheath, three wire cores arranged in the inner sheath, a separation protrusion fixedly connected to the bottom wall of the inner sheath, and the separation protrusion corresponds to the three wire cores, and fiber filler is filled between the outer sheath and the inner sheath.

[0009] As a preferred solution of the present invention, two tensile cores are provided in the inner sheath, and the two tensile cores are located between every two adjacent wire cores.

[0010] As a preferred solution of the present invention, two reinforcing cores are provided in the inner sheath, and the two reinforcing cores are located between every two adjacent wire cores.

[0011] As a preferred solution of the present invention, a U-shaped compression-resistant steel bar is fixedly connected between the inner and outer surfaces of the inner sheath.

[0012] As a preferred solution of the present invention, a first tensile steel wire is fixedly connected between the inner and outer surfaces of the inner sheath, and the first tensile steel wire passes through the U-shaped compression steel bar, and a second tensile steel wire is fixedly connected between the inner and outer surfaces of the outer sheath.

[0013] As a preferred solution of the present invention, the inner surfaces of the outer sheath and the inner sheath are both fixedly connected with an insulating inner sheath.

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) In this solution, under normal conditions, the inner sheath is kept close to the ground by its internal weight, which facilitates the heat dissipation of the three cores while keeping the outer sheath and fiber filler upward. When the cable is subjected to external pressure, the outer sheath and fiber filler protect the outside of the three cores, effectively preventing the three cores from being squeezed and damaged.

[0017] (2) In this solution, the separation protrusions separate the three wire cores into a fan-shaped distribution. When a special situation occurs and the bottom surface of the inner sheath leaks out and is subjected to external pressure, the inner sheath will be concave, causing the three fan-shaped wire cores to squeeze the fiber filling into the outer sheath. The fiber filling protects the three concave wire cores from pressure and prevents damage to the wire cores. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In this embodiment, the three cores 3 are located in the inner sheath 2 and are separated into a fan-shaped distribution by the dividing protrusions 4. The inner sheath 2 is arranged in the outer sheath 1. The bottom of the inner sheath 2 is a plane. Under the action of gravity, the plane of the inner sheath 2 always remains in contact with the ground, and the curved surface of the outer sheath 1 is upward. The outer sheath 1 buffers the external pressure through the fiber filler 5, thereby protecting the three cores 3 in the inner sheath 2. When a special situation occurs and the bottom surface of the inner sheath 2 leaks out and is squeezed, the inner sheath 2 will be concave, causing the three fan-shaped cores 3 to be squeezed into the outer sheath 1. The fiber filler 5 in the outer sheath 1 provides pressure protection for the three cores 3 in the inner sheath 2.

[0027] Specifically, two tensile cores 6 are provided in the inner sheath 2 , and the two tensile cores 6 are located between every two adjacent wire cores 3 .

[0028] In this embodiment, the two tensile cores 6 are made of hemp rope and are arranged between the three cores 3 to prevent the three cores 3 from squeezing each other and improve the tensile strength of the entire cable.

[0029] Specifically, two reinforcing cores 7 are provided in the inner sheath 2 , and the two reinforcing cores 7 are located between every two adjacent wire cores 3 .

[0030] In this embodiment, two reinforcing cores 7 are located in the middle of the entire cable to improve the strength of the entire cable.

[0031] Specifically, a U-shaped compression-resistant steel bar 8 is fixedly connected between the inner and outer surfaces of the inner sheath 2 .

[0032] In this embodiment, the U-shaped compression steel bars 8 are arranged at intervals to strengthen the bottom strength of the inner sheath 2 and improve the protection effect of the three cores 3.

[0033] Specifically, a first tensile steel wire 9 is fixedly connected between the inner and outer surfaces of the inner sheath 2 , and the first tensile steel wire 9 passes through the U-shaped compression steel bar 8 , and a second tensile steel wire 10 is fixedly connected between the inner and outer surfaces of the outer sheath 1 .

[0034] In this embodiment, the plurality of first tensile steel wires 9 and the plurality of second tensile steel wires 10 improve the tensile properties of the outer sheath 1 and the inner sheath 2 , thereby increasing the service life of the outer sheath 1 and the inner sheath 2 .

[0035] Specifically, the inner surfaces of the outer sheath 1 and the inner sheath 2 are both fixedly connected with an insulating inner sheath 11 .

[0036] In this embodiment, the two insulating inner sheaths 11 provide insulation protection for the three wire cores 3 to prevent electrical leakage and water seepage of the cable.

[0037] Working principle: Under the action of gravity, the plane of the inner sheath 2 always keeps in contact with the ground, and the curved surface of the outer sheath 1 is upward. The outer sheath 1 buffers the external pressure through the fiber filler 5, thereby protecting the three wire cores 3 in the inner sheath 2. When a special situation occurs and causes the bottom surface of the inner sheath 2 to leak out and be squeezed, the inner sheath 2 will be concave, causing the three fan-shaped wire cores 3 to be squeezed into the outer sheath 1. The fiber filler 5 in the outer sheath 1 provides pressure protection for the three wire cores 3 in the inner sheath 2.
