[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0031] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A special disinfection device for positive pressure connectors includes a gripping and rotating drive assembly 1, an injection assembly 3, a rotating mounting and locking assembly 2, and a disinfection assembly 4. The gripping and rotating drive assembly 1 includes a cylindrical housing 11 and a rotating drive assembly 12. The cylindrical housing 11 is connected to the rotating drive assembly 12. The rotating mounting and locking assembly 2 is connected to both the cylindrical housing 11 and the rotating drive assembly 12.

[0032] When this utility model is in use, when the pushing end of the injection component 3 is pressed, the disinfectant in the injection component 3 flows out from the rotary mounting locking component 2 and drips onto the threaded structure of the infusion tube connector. The disinfection component 4 is then fitted onto the threaded structure of the infusion tube connector. At this time, the pushing end of the injection component 3 drives the rotary drive component 12 to move, the rotary drive component 12 drives the rotary mounting locking component 2 to rotate, and the rotary mounting locking component 2 drives the disinfection component 4 to rotate. The disinfection component 4 rotates and disinfects the threaded structure of the infusion tube connector, thereby achieving thorough disinfection of the threaded structure of the infusion tube connector.

The top of the rotary mounting locking assembly 2 is inserted into the cylindrical housing 11 and rotatably connected. One end of the spring 123 is fixedly connected to the inner bottom of the cylindrical housing 11, and the other end of the spring 123 is fixedly connected to the bottom surface of the sliding sleeve 121.
[0034] In some embodiments, the rotating mounting and locking assembly 2 includes a rotating assembly 21, a mounting assembly 22, and a locking assembly 23; the top of the rotating assembly 21 is inserted into the cylindrical housing 11 for rotational connection, and the top of the rotating assembly 21 passes through the sliding sleeve 121 and is connected to the injection assembly 3; the mounting assembly 22 is mounted on the bottom of the rotating assembly 21; the locking assembly 23 is connected to the mounting assembly 22; the mounting assembly 22 is used in conjunction with the sterilization assembly 4 for disassembly and detachment; and the top of the rotating assembly 21 is used in conjunction with the bottom of the injection assembly 3 for disassembly and detachment.
[0035] Specifically, the rotating assembly 21 includes a rotating rod 211; the top of the rotating rod 211 is inserted into the cylindrical housing 11 for rotatable connection; the outer wall of the rotating rod 211 has a helical groove 212; the outer wall of the sliding sleeve 121 is fixedly provided with a slider, which is inserted into the helical groove 212 for slidable connection; the top of the rotating rod 211 passes through the sliding sleeve 121; the upper and lower end faces of the rotating rod 211 have through grooves 213; the top of the through grooves 213 is used in conjunction with the injection assembly 3 for disassembly and detachment; the top of the mounting assembly 22 is connected to the bottom of the rotating rod 211. The outer wall of the sliding sleeve 121 is limited to slide within the inner wall of the cylindrical housing 11, allowing the sliding sleeve 121 to slide up and down only within the cylindrical housing 11.
[0036] The mounting component 22 includes a mounting sleeve 221 and multiple balls 223. The mounting sleeve 221 is fixedly mounted on the bottom of the rotating rod 211. The inner and outer walls of the mounting sleeve 221 are equally spaced through sliding holes 222 for use in limiting and sliding connection with the balls 223. Each sliding hole 222 contains a ball 223. The top of the disinfection component 4 can be inserted into the interior of the mounting sleeve 221 from the bottom. The balls 223 are used in conjunction with the disinfection component 4 for disassembly and use. The locking component 23 is connected to the mounting sleeve 221 and the balls 223.
[0037] The locking assembly 23 includes a locking sleeve 231 and a second spring 233. The top of the locking sleeve 231 is slidably sleeved on the bottom outer side of the rotating rod 211, and the inner wall of the locking sleeve 231 is slidably connected to the outer wall of the mounting sleeve 221. The bottom inner wall of the locking sleeve 231 is provided with an inclined surface 232 for sliding with the ball 223. One end of the second spring 233 is fixedly connected to the inner top of the locking sleeve 231, and the other end of the second spring 233 is fixedly connected to the outer top surface of the mounting sleeve 221.
[0038] When using this utility model, when disassembling and assembling the disinfection component 4, the second mounting sleeve 41 is inserted into the first mounting sleeve 221, and the locking sleeve 231 is pushed down. The locking sleeve 231 slides down along the first mounting sleeve 221 and compresses the second spring 233. The inclined surface 232 on the locking sleeve 231 contacts and slides in close contact with the ball 223. Under the pushing action of the inclined surface 232, the ball 223 slides in the sliding hole 222, causing the ball 223 to move towards the outer wall of the second mounting sleeve 41 and be engaged in the annular groove 42. At this time, the ball 223 is firmly engaged with the annular groove 42 under the squeezing action of the inner wall of the locking sleeve 231, thereby realizing the convenient installation of the disinfection component 4.
[0039] In some embodiments, the injection assembly 3 includes a syringe body 31, a push rod 32, a piston 33, and an injection tube 34; the bottom of the push rod 32 is fixedly connected to the top of the piston 33, the outer wall of the piston 33 is slidably connected to the inner wall of the syringe body 31, the injection tube 34 is fixedly installed at the bottom of the syringe body 31, the bottom of the injection tube 34 can be inserted into the interior of the cylindrical housing 11, and the injection tube 34 is detached and removable from the inner wall of the through groove 213, and the top push block of the push rod 32 is used to press against the top of the slide rod 122.
[0040] Preferably, the injection tube 34 is inserted into the through groove 213 for disassembly and use.
[0041] When this utility model is in use, by pressing down on the push rod 32, the push rod 32 drives the piston 33 to slide down along the inner wall of the syringe body 31, and the disinfectant in the syringe body 31 flows out from the injection tube 34 and drips down along the through groove 213.
[0042] When the push rod 32 is pressed down, the push rod 32 presses the slide rod 122 downward. The slide rod 122 drives the slide sleeve 121 to slide downward along the inner wall of the cylindrical housing 11. While the slide sleeve 121 presses the spring 123, the slider on the inner wall of the slide sleeve 121 slides in the spiral groove 212, which causes the rotating rod 211 to rotate. Then the rotating rod 211 rotates and drives the mounting assembly 22 to rotate. The mounting assembly 22 drives the sterilization assembly 4 to rotate. When the piston 33 moves to the inner bottom of the syringe body 31, the push rod 32 is released. Under the elastic force of the spring 123, the slide sleeve 121 slides upward to reset. The slide sleeve 121 drives the slide rod 122 to reset. The slide rod 122 drives the push rod 32 and the piston 33 to reset.

[0044] The inner wall of the cleaning liner 43 has an internal thread shape, which facilitates cleaning of infusion set connectors with threaded structures. The cleaning liner 43 is made of cotton.
[0045] When this utility model is in use, the internal thread shape of the cleaning liner 43 achieves a high degree of fit with the thread structure of the infusion set connector, thereby achieving thorough disinfection. Furthermore, the cleaning liner 43 is made of cotton material, which can absorb disinfectant.
[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
