DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention but not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative labor are all within the protection scope of the present invention.

[0020] like Figures 1 to 5As shown, an easy-to-insert and anti-dropout needle-type medical infusion butyl rubber plug comprises a body 1, wherein the body 1 comprises a filling portion 2 extending into the bottle mouth, and also comprises a sealing component 3 for the bottle mouth, wherein the filling portion 2 is provided with a partition 4 for layering the filling portion 2 to reduce the needle insertion resistance, and the sealing component 3 comprises a sealing ring 5 for sealing the bottle mouth, wherein the outer circumference of the sealing ring 5 is provided with a flange for preventing the sealing ring 5 from falling off, and a limiting component 7 for limiting the needle tube to prevent the needle from falling off is distributed inside the sealing ring 5; and a protrusion 8 is provided on the circumference of the flange to prevent the body 1 from falling off from the medicine bottle.

[0021] The partitions 4 include a plurality of partitions distributed along the axis of the filling portion 2, a cavity 41 is formed between two adjacent partitions 4 and the cavity 41 is penetrated on both sides; the end of the filling portion 2 is tapered for easy insertion into the medicine bottle, the partitions 4 reduce the actual area of ​​the filling portion 2, thereby reducing the resistance to needle insertion, and the cavity 41 is penetrated on both sides for easy one-piece molding; the cavity 41 is partially in close contact with the bottle mouth, and no drug solution will remain in the cavity 41.

[0022] The middle of each partition 4 is provided with a first tapered cavity 42 for easy insertion of a needle.

[0023] The limiting assembly 7 includes a receiving cavity 71 arranged on the sealing ring 5, a catheter 72 for assisting the needle tube guide is provided at the center of the receiving cavity 71, and the receiving cavity 71 is threadedly matched with a locking assembly 73 for increasing the friction between the catheter 72 and the needle tube by squeezing the end of the catheter 72.

[0024] The locking assembly 73 includes a rotating column 731 threadably matched with the accommodating cavity 71 , and an extrusion cavity 732 matched with the conduit 72 is disposed in the rotating column 731 .

[0025] The extrusion cavity 732 includes a straight section 734 and a tapered section 735 in sequence along the axial direction. The tapered section 735 cooperates with the conduit 72 to extrude the end of the conduit 72 .
