Embodiment 1
[0039] figure 1 Shown is the invention's 1 In the embodiment of the guide wire, the metal wire material of the metal core wire 1 is made of nickel-titanium alloy. The metal core wire 1 has a base section 4 with a diameter of 0.78mm (300cm in the present embodiment); a middle section 5 with a diameter of 0.65mm extending continuously to the front end (30cm in the present embodiment); The conical section 6 (15cm in the present embodiment) that the front end shrinks continuously. The middle section is colored with yellow and black pigments containing barium sulfate polyurethane resin tubes (the length of each tube is 8mm), which is continuously and alternately covered to form a 20cm-long straight line composed of the first and second direct-viewing sign color rings 9 and 10. View logo section 2. Look directly at the base section 4 ends of the sign portion 2, use 2 polyurethane resin tubes colored by red pigments, sandwich the above-mentioned yellow and black signs, and set...
Embodiment 2
[0041] From the base section 4 of diameter 0.78mm (being 300cm in the present embodiment), make the conical section 6 (being 45cm in the present embodiment) of continuous dwindling to the front end of diameter 0.15mm, with the sulfuric acid containing yellow and black pigment coloring The polyurethane resin tube of barium (each tube length is 8mm), is successively and alternately set on the above-mentioned guide wire, forms the direct-view mark part 2 that is made up of the first and second direct-view mark color rings 9, 10 of 25cm long. At the 4 ends of the base section of the direct-viewing sign part 2, two polyurethane resin tubes colored with red pigments are used to clamp the above-mentioned yellow and black signs, and the interval is 10cm, so that the first, second and third direct-viewing sign color circles The direct vision marking part 2 composed of 9, 10, and 11 can more accurately prompt the position where the guide wire is inserted. A platinum coil is installed in...
