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.

Abstract

The application discloses an anesthesia catheter, which includes a catheter body. The catheter body has a tube wall that encloses a drug channel. The anesthesia catheter also includes a metal wire that is fixedly connected in the tube wall. The metal wire is linear and runs along the catheter wall. The length of the body extends; the tensile strength of the metal wire is less than that of the catheter body. The metal wire is linear, and the tensile strength of the metal wire is less than that of the catheter body, so that during the process of pulling out the catheter, if the anesthesia catheter is stuck by human bones or knotted in the body, resulting in greater resistance , if still using a larger force to pull the anesthesia catheter, the metal wire will break first than the catheter body. At this time, the medical staff can get a greater force feedback, that is, feel the feeling of the wire breaking, and the medical staff can Stop the pull-out action, adjust the patient's position in time to remove the anesthesia catheter, or temporarily suspend the removal process, and wait for a better opportunity to avoid catheter breakage.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to an anesthesia catheter. Background technique [0002] The anesthesia catheter is usually made of polymer materials such as plastic. Although its breaking force is relatively high, its elongation at break is relatively large, and there is a long thinning process before it is broken. A small force can make the anesthesia catheter thinner from its original state (such as outer diameter 1.0mm), and the stretched length will be more than twice the original before breaking. Therefore, when the anesthesia catheter is stuck by human bones or When a knot is knotted in the human body, it is not easy to be found in the process of pulling the anesthesia catheter until the anesthesia catheter is pulled off, but at this time the broken part has remained in the human body and is difficult to remove. [0003] In the prior art, a helical steel wire is arranged in the anesthesia...
