Embodiment approach 1
[0046] Embodiment 1: In this embodiment, if image 3 As shown, there are multiple drug outlets 15, which are opened on the tube wall 11 and arranged along the circumference of the catheter body 1, so that the drug flows out from the outer periphery of the catheter body 1 and flows uniformly to the Improve the effect of anesthesia on the injured site.
[0047] Further, the drug outlet 15 and the metal wire 3 are misplaced to prevent the metal wire 3 from hindering the flow of the drug, and to prevent the drug from reacting with the metal wire 3. Intensity affects.
Embodiment approach 2
[0048] Embodiment 2: In this embodiment, the drug outlet 15 is opened at one end of the catheter body 1, and the axis of the drug outlet 15 coincides with the axis of the drug channel 12, so that the drug can flow along the The catheter body 1 flows out along the length direction, and flows directly to the injured site, avoiding bending of the drug channel 12 and reducing the flow speed of the drug, thereby reducing the injection efficiency.
[0049] As a preferred embodiment of the present application, the diameter of the metal wire 3 is 0.05-0.2mm.
[0050] In practical applications, the outer diameter of the catheter body 1 is usually about 1 mm, so the diameter of the metal wire 3 is 0.05-0.2 mm, which can ensure better support for the catheter body 1 and effectively improve the On the premise of the strength of the catheter body 1, the metal wire 3 should be as thin as possible, so that when the anesthesia catheter is subjected to greater resistance in the length directio...
Embodiment 1
[0066] Embodiment 1: In this embodiment, the softening part 2 is a hollow structure, so as to reduce the weight of the softening part 2, reduce the compression of the softening part 2 on the internal tissue of the human body, and avoid causing serious damage to the injured or sick. injury.
