Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a medical cable with a gas-conducting function. Background Art

[0002] At present, after laying medical cables, a hollow air duct needs to be built next to them for matching use. The step-by-step laying project is too long and the laying cost is high. It is necessary to design a cable with signal transmission and air conduction functions. This cable also needs to have high shielding, impact resistance and pressure resistance. Therefore, a medical cable with air conduction function is proposed. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a medical cable with a gas conducting function in view of the above shortcomings.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A medical cable with an air-conducting function comprises a conductor, a plurality of hollow air-conducting tubes, a wrapping layer and a foam filler. The plurality of hollow air-conducting tubes are arranged in a cluster and have a circular cross-section. All the hollow air-conducting tubes are wrapped in the wrapping layer. A first armor layer is arranged on the outside of the wrapping layer. A gap is formed between the wrapping layer and the first armor layer. The conductor is arranged in the gap. Other areas in the gap are filled with foam fillers. A fireproof layer, an inner protective layer, a second armor layer and an outer protective layer are arranged on the outside of the first armor layer in sequence.

[0006] Furthermore, the hollow air guide tube is made of silicone, has an outer diameter of 12 mm, and a tube wall thickness of 1 mm.

[0007] Furthermore, the foam filler is a foamed polyethylene material.

[0008] Furthermore, the first armor layer and the second armor layer are both copper tape armor layers, the copper tape thickness of the first armor layer is less than the copper tape thickness of the second armor layer, and the copper tape thickness of the second armor layer is 0.5 mm.

[0009] Furthermore, the inner protective layer and the outer protective layer are both made of EPDM rubber.

[0010] Furthermore, the fireproof layer is a magnesium oxide powder filling layer.

[0011] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0012] The utility model provides a hollow air duct so that the medical cable has both a signal transmission function and a gas transmission function; by filling the outer side of the winding layer with foamed polyethylene material, the foamed polyethylene can not only absorb vibration and impact, thereby effectively protecting the hollow air duct, but also has a relatively low thermal conductivity, which can effectively isolate the heat generated by the wire and ensure that the gas in the hollow air duct is at room temperature; the first armor layer, the inner protective layer, the second armor layer and the outer protective layer are staggered and overlapped, the ethylene propylene rubber of the inner protective layer and the outer protective layer has good impact elasticity and can absorb external impact well, and the copper tapes of the first armor layer and the second armor layer can improve the mechanical strength of the cable and have good shielding properties, and the external impact is weakened layer by layer through the outer protective layer, the second armor layer, the inner protective layer and the first armor layer, so as to protect the hollow air duct inside the cable, so that the cable has good impact resistance and pressure resistance; by providing a plurality of hollow air ducts, a plurality of branches can be divided into the output end of the cable, which are respectively connected to a plurality of medical gas transmission equipment, so as to facilitate the use of a plurality of medical gas transmission equipment.

[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0018] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", "clockwise", "counterclockwise", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0019] like Figure 1As shown, a medical cable with an air guiding function comprises a conductor 1, a plurality of hollow air guiding tubes 2, a wrapping layer 3 and a foam filler 4, wherein the plurality of hollow air guiding tubes 2 are gathered and arranged and have a circular cross-section, and all the hollow air guiding tubes 2 are wrapped in the wrapping layer 3, a first armor layer 6 is arranged on the outside of the wrapping layer 3, a gap is formed between the wrapping layer 3 and the first armor layer 6, a conductor 1 is arranged in the gap, and other areas in the gap are filled with the foam filler 4, and a fireproof layer 7, an inner protective layer 8, a second armor layer 9 and an outer protective layer 10 are arranged on the outside of the first armor layer 6 in sequence.

[0020] As an implementation manner, the hollow air guide tube 2 is made of silicone, and the outer diameter of the hollow air guide tube 2 is 12 mm and the tube wall thickness is 1 mm.

[0021] As an implementation manner, the foam filler 4 is a foamed polyethylene material.

[0022] As an implementation manner, the first armor layer 6 and the second armor layer 9 are both copper tape armor layers, the copper tape thickness of the first armor layer 6 is less than the copper tape thickness of the second armor layer 9, and the copper tape thickness of the second armor layer 9 is 0.5 mm.

[0023] As an implementation mode, the inner protective layer 8 and the outer protective layer 10 are both made of EPDM rubber.

[0024] As an implementation mode, the fireproof layer 7 is a magnesium oxide powder filling layer.

[0025] In the utility model, the foamed polyethylene filler has a low density, light weight, and certain elasticity, so it can effectively absorb the vibration and impact inside the cable. The thermal conductivity of the foamed polyethylene is also relatively low, which can effectively reduce the temperature inside the cable. The EPDM rubber has good electrical insulation, chemical resistance, impact elasticity, acid and alkali resistance, and low specific gravity.

[0026] The working process of the utility model is as follows: when the medical cable is in use, the foam filler 4 foam polyethylene insulates the heat generated by the conductor 1, so that the gas temperature inside the hollow airway tube 2 is not affected. When subjected to external impact, the outer protective layer 10, the second armor layer 9, the inner protective layer 8 and the first armor layer 6 weaken the external impact layer by layer, thereby protecting the hollow airway tube 2 and avoiding affecting gas transportation.

[0027] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field. The protection scope of the utility model is based on the content of the claims, and any equivalent transformation based on the technical inspiration of the utility model is also within the protection scope of the utility model.
