Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an eight-core medical cable resistant to chemical corrosion. Background Technology

[0002] Medical cables are widely used in medical equipment such as medical X-ray machines, CT scanners, MRI machines, ultrasound machines, electrocardiographs, and hemodialysis machines. For sterilization, medical cables need to be compatible with various chemical sterilization methods, such as ethylene oxide disinfection, glutaraldehyde immersion, and isopropanol wiping.

[0003] Chinese patent document CN211507165U discloses a special oil-resistant, corrosion-resistant, and torsion-resistant cable for medical equipment. This patent uses cotton yarn to support each core wire, making the core wire more round and compact. However, the cotton yarn is not pressure-resistant and has poor torsion resistance. In addition, the core wires are in contact with each other, resulting in greater squeezing and wear between the core wires. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chemically resistant eight-core medical cable, comprising one first core wire and seven second core wires, the seven second core wires being arranged in a ring about the axis of the first core wire, and all seven second core wires being wrapped with a wrapping tape. A hollow filler strip is provided between the first core wire and two adjacent second core wires. The outer wall of the hollow filler strip is provided with several ring-shaped U-shaped strips. The two end faces of the U-shaped strips away from the hollow filler strip are arc-shaped convex surfaces. The wrapping tape is wrapped with a fluoroplastic sheath, and the fluoroplastic sheath is wrapped with a platinum silicone rubber sheath.

[0006] Optionally, the first core wire and the second core wire have the same structure. The second core wire includes a silver-plated copper wire, a fluoroplastic insulating tube extruded over the silver-plated copper wire, and aluminum foil Mylar extruded over the fluoroplastic insulating tube.

[0007] Optionally, a glass fiber rope is provided between the inner wall of the wrapping tape and the two adjacent second core wires, and the surface of the glass fiber rope is provided with a metal hydrate flame retardant coating.

[0008] Optionally, the end face of the hollow filler strip is provided with a plurality of light-reducing holes, and the plurality of light-reducing holes and the plurality of C-shaped strips are staggered about the axis of the hollow filler strip.

[0009] Compared with the prior art, the present invention has the following advantages: The present invention has a compact arrangement and a round structure. The first core wire and the second core wire are separated and supported by the hollow filling strip, which can significantly improve the compressive strength and torsional strength of the cable. The platinum silicone rubber sheath has good chemical corrosion resistance and a long service life. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example: Please refer to Figure 1 This utility model provides a chemically resistant eight-core medical cable, comprising one first core wire 1 and seven second core wires 2. The first core wire 1 and the second core wires 2 have the same structure. Each second core wire 2 includes a silver-plated copper wire 6, a fluoroplastic insulating tube 7 extruded over the silver-plated copper wire 6, and an aluminum foil Mylar 8 extruded over the fluoroplastic insulating tube 7. The seven second core wires 2 are arranged in a ring about the axis of the first core wire 1, and are all covered with a wrapping tape 3. The wrapping tape 3 is covered with a fluoroplastic sheath 4, and the fluoroplastic sheath 4 is covered with a platinum silicone rubber sheath 5. The platinum silicone rubber sheath 5 is made of platinum vulcanized flame-retardant silicone rubber, which has good thermal stability, corrosion resistance, and flexibility. It is harmless, non-toxic, odorless, strongly resistant to ultraviolet rays, and has good resistance to ethylene oxide, glutaraldehyde, and isopropanol.

[0015] Based on the above embodiment, a hollow filler strip 9 is provided between the first core wire 1 and the two adjacent second core wires 2. Please refer to [link / reference]. Figure 2The hollow filler strip 9 has several annularly arranged U-shaped strips 10 on its outer wall. The hollow filler strip 9 and the U-shaped strips 10 are integrally formed, and the hollow filler strip 9 is made of PP material. The two end faces of the U-shaped strips 10 away from the hollow filler strip 9 are arc-shaped convex surfaces. This utility model improves the tensile strength and torsional strength of the cable through the hollow filler strip 9. The U-shaped strip 10 is integrally formed from two thicker ribs and a thinner rib located between the two thicker ribs. The thicker ribs are easy to deform and can provide a pressure-resistant buffer effect for the compression between the first core wire 1 and the second core wire 2, while the thinner rib connects the two thicker ribs and can strengthen the torsional strength of the hollow filler strip 9, thereby improving the torsional strength of the cable. The end face of the hollow filler strip 9 is provided with a number of lightening holes 11. The number of lightening holes 11 and the number of C-shaped strips 10 are staggered about the axis of the hollow filler strip 9. The lightening holes 11 lighten the hollow filler strip 9 while improving the flexibility of the hollow filler strip 9.

[0016] This utility model features a compact arrangement and a rounded structure. The hollow filler strip 9 separates and supports the first core wire 1 and the second core wire 2, significantly improving the cable's compressive and torsional strength. The platinum silicone rubber sheath 5 provides excellent chemical corrosion resistance and a long service life. Specifically, the first core wire 1 and the second core wire 2 do not contact each other; the second core wire 2 only contacts its adjacent second core wire 2, minimizing inter-core wear and compression.

[0017] Based on the above embodiment, a fiberglass rope 12 is provided between the inner wall of the wrapping tape 3 and the two adjacent second core wires 2. The surface of the fiberglass rope 12 is coated with a metal hydrate flame-retardant adhesive coating. When exposed to open flame, the metal hydrate flame-retardant adhesive coating decomposes into metal oxides and precipitates water of crystallization. The metal oxides adsorb onto the surface of the fiberglass cloth to form a porous shell. This shell has a certain adsorption effect on smoke. In addition, the precipitated water of crystallization not only has a cooling effect, but also has a significant effect on the settling of smoke particles during combustion. When the wrapping tape 3, fluoroplastic sheath 4, and platinum silicone rubber sheath 5 are damaged by fire, the fiberglass rope 12 can directly contact the flame to achieve the flame-retardant function.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
