Detailed Description
The following description is given by way of example only, and is not intended to limit the scope of the invention.
Referring to fig. 1 to 4, which illustrate a preferred embodiment of the present invention, a catheter 1 for a vehicle according to the present invention includes an inner tube 10 and a metal layer 20.
The metal layer 20 includes at least one wire 21 wound around the outer circumferential surface of the inner tube 10 along an axial direction of the inner tube 10, and the at least one wire 21 physically covers the outer circumferential surface of the inner tube 10 and can physically completely peel off the inner tube 10. Wherein, the physical covering and connecting method includes mutual embedding, tightening or glue adhesion. Therefore, all layers of the catheter 1 are easy to be completely stripped from each other, and classification treatment is facilitated without additional processing after replacement.
The inner tube 10 includes a plurality of spiral protrusions 11 spirally extending and protruding on the outer peripheral surface of the inner tube 10, the plurality of spiral protrusions 11 are disposed at intervals, a spiral recess 12 is defined between two adjacent ones of the plurality of spiral protrusions 11, each of the wires 21 is partially accommodated in one of the spiral recesses 12, and the at least one wire 21 and the inner tube 10 can be prevented from being dislocated from each other. In detail, the plurality of spiral protrusions 11 may be a plurality of sections extending continuously, or may be respectively disposed on the outer circumferential surface of the inner tube 10. When in use, the inner tube 10 can accommodate an inner wire 2, and the outer peripheral surface of the inner tube 10 can be stably jointed with the at least one wire 21. The thickness of the metal layer 20 is preferably greater than the thickness of the inner tube 10, increasing the mechanical strength of the catheter 1.
In detail, the at least one wire 21 includes a plurality of segments 211, each segment 211 corresponds to one of the spiral concave parts 12; a gap 212 is formed between two adjacent segments 211, and each of the rotary protrusions 11 is a ridge-shaped and at least partially embedded in one of the gaps 212, so that the at least one wire 21 can be stably combined with the inner tube 10. In the present embodiment, the at least one wire 21 is a flat metal wire, and two adjacent segments 211 are abutted to cover the inner tube 10 more completely, so as to increase the structural strength and facilitate the bending configuration. In other embodiments, the at least one wire may also be a metal wire with other shapes such as a circular shape, an oval shape, or a square shape, or comprise a plurality of metal wires; the plurality of segments may also be spaced apart; each rotary protrusion can also be in a trapezoid shape, a rectangular shape or an arc shape according to the configuration requirement.
The conduit 1 further includes an outer layer 30 covering the metal layer 20, the outer layer 30 physically covers the outer circumferential surface of the metal layer 20 and can physically completely peel off the metal layer 20, so as to fix the metal layer 20 and prevent abrasion and corrosion, and facilitate classification after replacement. The at least one wire 21 is radially embedded in the outer layer 30; the depth of the at least one wire 21 embedded in the outer layer 30 is not less than the depth of the rotation recess 12, so that the stability of the combination between the layers can be increased to avoid the mutual dislocation. The thickness of the metal layer 20 is greater than that of the outer layer 30, so as to prevent the catheter 1 from being difficult to bend and install due to the excessive thickness of the outer layer 30.
