[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0022] It should be noted that when an element is referred to as being "fixed on", "set on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a central element at the same time. Furthermore, when an element is considered to be "fixedly connected" to another element, the two may be fixed in a detachable manner or in a non-detachable manner, such as socketing, snap-fitting, integrally molded fixing, welding, etc., which can be achieved in the prior art and will not be described in detail here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0025] Combined with attachment Figure 1-3 , an implantable drug delivery needle in this embodiment includes a needle tube 1, a metal sleeve 2, a conductive wire 3, a wing seat 4 and a display tube 5. The metal sleeve 2 is movably installed in the wing seat 4, and a movable channel 43 matching the metal sleeve 2 is provided in the wing seat 4. The needle tube 1 is conductive and fixedly connected to the metal sleeve 2. The needle tip of the needle tube 1 extends from the front end of the metal sleeve 2. When the metal sleeve 2 is at the front end of the wing seat 4, the needle tip extends from the front end of the wing seat 4. One end of the conductive wire 3 is arranged on the inner side of the front end of the wing seat 4. When the metal sleeve 2 moves to the front end of the wing seat 4, it is electrically connected to the conductive wire 3. The other end of the conductive wire 3 is arranged at the handle of the wing seat 4 and is integrally injection molded on the surface of the wing seat handle. The middle of the conductive wire 3 is connected to the display tube 5, and the conductive wire 3 is electrically connected to the metal sleeve 2.

[0026] When the medical staff performs a puncture, the handle of the wing seat 4 is used for puncture for the first time. When the needle tip of the needle tube 1 contacts the metal of the port body base, the display tube 5 lights up due to the potential difference between the metal of the port body base and the needle tube 1. At this time, it prompts the medical staff operating the display tube that the needle has been inserted into place, otherwise it has not been inserted into place.

[0027] As a preferred solution of the present invention, the display tube 5 is a neon bulb or a diode.

[0028] As a preferred embodiment of the present invention, the wing seat 4 includes a wing seat sleeve 41 and a handle 42 provided on both sides of the wing seat sleeve 41. A movable channel 43 is provided inside the wing seat sleeve 41. The metal sleeve 2 is movably assembled in the movable channel 43. The metal sleeve 2 can slide back and forth in the movable channel 43. The metal sleeve 2 as a whole can extend from the front end of the wing seat sleeve 41. The needle tube 1 is connected to a catheter 7. Figure 2 As shown, when the medical staff completes the puncture, the curved catheter 7 drives the wing seat 4 to make it form a 90-degree angle with the needle tube to fix the wing seat 4. When the skin of obese patients, breast tumor patients or patients doing exercise moves, the catheter 7 and the wing seat 4 can be moved to adjust the withdrawal tension of the needle tube. At the same time, the softness and length of the conductive wire 3 can always keep in contact with the metal sleeve 2, so that the position of the needle tip can be confirmed in real time.

[0029] As a preferred solution of the present invention, the outer diameter of the front end of the metal sleeve 2 is larger than the outer diameter of the rear end, the inner diameter of the front end of the active channel 43 is larger than the inner diameter of the rear end, and the outer diameter of the front end of the metal sleeve 2 is smaller than the inner diameter of the rear end of the active channel 43. When the metal sleeve 2 moves to the rear end of the active channel 43, the front end of the metal sleeve 2 will be stuck in the rear end of the active channel 43. At this time, the needle tip of the needle tube 1 is also located in the active channel 43 to prevent it from being exposed and injuring medical staff.

[0030] As a preferred solution of the present invention, at least two mutually abutting spring pieces 6 are provided in the movable channel 43. When the front end of the metal sleeve 2 is stuck in the rear end of the movable channel 43, multiple spring pieces 6 abut against each other to form a needle protection cover. The needle of the needle tube 1 is now located in the needle protection cover formed by multiple spring pieces 6 to prevent harm to medical staff.

[0031] As a preferred solution of the present invention, the catheter 7 is provided with a flow-stop clamp 8 , a Luer connector 9 and a sealing cap 10 .

[0032] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
