DETAILED DESCRIPTION

[0020] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0021] The first implementation method:

[0022] Figure 1-5The Luer connector dissolver is shown, comprising a tube body 1, a sealing plug 2 is slidably inserted into the interior of the tube body 1, a pull rod 3 is fixedly connected to the lower end of the sealing plug 2, a connector 4 is fixedly connected to the upper end of the tube body 1, and the connector 4 is a spiral head-like structure that can be quickly connected to a variety of conventional needles and medical tubing. The outer end of the tube body 1 is sleeved with a movable ring 5, a pair of compression springs 6 are fixedly connected to the inner wall of the movable ring 5, and the ends of the pair of compression springs 6 that are close to each other are fixedly connected to a movable block 7, and the end of the movable block 7 that is away from the compression spring 6 is fixedly connected to a sponge block 8. A pair of plug-in tubes 9 are fixedly connected to the inner wall of the movable ring 5, and the outer end of the tube body 1 is provided with a pair of plug-in grooves 10 that are slidably inserted with the plug-in tubes 9;

[0023] The internal sliding sleeve of the compression spring 6 is provided with a reinforcement rod 13, and the end of the movable block 7 close to the compression spring 6 is provided with a reinforcement groove 12 which is slidably inserted with the reinforcement rod 13. One end of the movable block 7 extends from the compression spring 6 and is inserted into the reinforcement groove 12. The inner diameter of the compression spring 6 is larger than the diameter of the reinforcement groove 12. The outer end of the tube body 1 is engraved with a scale line 11, and the outer end of the tube body 1 is fixedly sleeved with a fixed block 19. In the initial state, the compression spring 6 is in a contracted state, and the lower end of the movable ring 5 contacts the upper end of the fixed block 19.

[0024] After the needle is installed on the joint 4, the movable ring 5 is moved to drive the sponge block 8 to move toward the needle until the sponge block 8 is separated from the tube body 1. Since the compression spring 6 is in a contracted state when the sponge block 8 contacts the tube body 1, after the sponge block 8 is separated from the tube body 1, under the action of the elastic force of the compression spring 6, the compression spring 6 will push the movable block 7 and the sponge block 8, so that the pair of sponge blocks 8 move toward the needle and contact the end of the needle with the needle tip, thereby covering the needle tip between the pair of sponge blocks 8, isolating the needle tip from foreign objects, and further, when moving the drug dissolver, it is not easy for the needle to accidentally pierce people, thereby improving the safety of people and making it difficult for the needle to be damaged by accidentally touching foreign objects.

[0025] After the pipeline is installed on the connector 4, the above steps are repeated and the pipeline is clamped by a pair of sponge blocks 8, thereby improving the stability of the pipeline on the dissolver.

[0026] The second implementation method:

[0027] This embodiment is based on the first embodiment, with the addition of structures such as a pull-out tube 14 and a limit block 20, and the rest of the structure remains the same as the first embodiment.

[0028] Figure 3 and Figure 5It is shown that a limit block 20 is inserted into the interior of the plug-in tube 9 for sliding, and the side end of the limit block 20 is fixedly connected to the pull-out tube 14. The outer end of the movable ring 5 is provided with a pair of circular holes 15 that are movably inserted with the pull-out tube 14. One end of the pull-out tube 14 movably passes through the circular hole 15 and is inserted into the plug-in tube 9. A pair of limit grooves 16 that are movably inserted with the limit block 20 are provided on the inner wall surface of the plug-in groove 10. The ends of the pair of plug-in tubes 9 that are close to each other are coated with a magnetic coating 17, and the inner wall surface of the plug-in groove 10 is coated with a magnetic coating 2 18.

[0029] When using the sponge block 8 to cover the needle tip or clamp the pipeline, it is necessary to push the pulling tube 14 so that the limit block 20 is inserted into the limit groove 16, thereby limiting the dynamic ring 5 and the sponge block 8, making it difficult to move, thereby improving the stability of the connection between the sponge block 8 and the needle tip or pipeline. At the same time, the magnetic coating 17 will be adsorbed together with the magnetic coating 2 18, thereby improving the stability of one end of the plug-in tube 9 in the plug-in groove 10, thereby improving the stability of the dynamic ring 5.

[0030] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
