[0049] Please refer to Figures 1 to 4, the first embodiment of the present application provides a medical device transfer pipe joint assembly 10 without glue and chemical solvents, which is used for connecting transfer pipes of medical devices. The medical device transfer pipe joint assembly 10 without glue and chemical solvents includes an upper anti-twist sleeve 11, an upper rotary buckle 12, and an upper transfer joint 13. The upper rotary buckle 12 includes an upper rotary buckle body 121, an upper reinforcement member 122, and a plurality of upper rotary reverse buckles 123. The upper transfer joint 13 is provided with an upper socket end 131, an upper connection end 132, an upper reverse buckle 1311, an upper rotating shell 1321, and an upper transfer pipe 1322. The medical device transfer pipe joint assembly 10 without glue and chemical solvents further includes a lower anti-twist sleeve 16, a lower rotary buckle 15, and a lower transfer joint 14. The lower transfer joint 14 is provided with a lower socket end 141, a lower connection end 146, a lower reverse buckle 145, a lower rotating shell 142, a lower transfer pipe 144, and a threaded ring portion. The medical device transfer pipe joint assembly 10 without glue and chemical solvents realizes docking through the engagement of the internal thread 1324 of the upper transfer joint 13 and the external thread 1411 of the threaded ring portion of the lower transfer joint 14, and relies on the buckling of the upper rotary reverse buckle 123 and the buckling of the lower rotary reverse buckle 153 to form an anti-loosening lock. During assembly, first, the upper transfer component is assembled: pass the upper anti-twist sleeve 11 through the transfer pipe and place it on the outside, put the transfer pipe into the upper rotary buckle body 121, so that the upper curved convex portion 1213 of the upper rotary buckle body 121 contacts the transfer pipe; then insert the upper insertion body 1314 of the upper reverse buckle 1311 of the upper transfer joint 13 into the transfer pipe, and realize preliminary fixation by embedding the upper reverse buckle head 1313 into the pipe wall; rotate the upper rotary buckle body 121 so that its upper internal thread meshes with the upper mating thread 1315 of the upper socket end 131, and press the transfer pipe through the thread pre-tightening force; finally, put the upper anti-twist body 111 of the upper anti-twist sleeve 11 onto the upper rotary buckle 12, and complete the anti-twist fixation by the multi-stage locking of the upper clamping through hole 1121 and the buckling of the upper rotary reverse buckle 123. After the lower anti-twist sleeve 16 passes through the transfer pipe, the lower rotary buckle body 151 contacts the pipe wall through the lower curved convex portion 1513, the lower insertion body 1452 of the lower reverse buckle 145 is inserted into the transfer pipe and is buckled by the lower reverse buckle head 1451, and the lower internal thread 1514 is screwed and pressed with the lower mating thread 1432 of the lower socket end 141. Finally, reverse locking is achieved through the buckling of the lower clamping through hole 1621 of the lower anti-twist sleeve 16 and the lower rotary reverse buckle 153. When the components are integrally connected, align and screw the internal thread 1324 of the upper transfer joint 13 and the external thread 1411 of the threaded ring portion of the lower transfer joint 14 to form a sealed flow channel. The communication structure of the upper transfer pipe 1322, the upper rotary buckle channel 1212, the lower rotary buckle channel 1511, and the lower transfer pipe 144 ensures unobstructed fluid transmission. The diameter of the upper rotary buckle channel 1212 is smaller than that of the transfer pipe, forming a pressure buffer zone to absorb hydraulic shock.The sealing of the transmission tube depends on the mechanical bite of the upper reverse buckle 1313 and the lower reverse buckle 1451 embedded in the tube wall, as well as the axial pressing force generated by the thread meshing, so that the transmission tube forms an axial compression deformation between the upper curved convex part 1213 and the lower curved convex part 1513, realizing glue-free sealing. The three-stage decreasing aperture of the upper anti-twist ring 112 is clamped with the through hole 1121 and the upper rotating reverse buckle 123 to form a progressive locking. The reverse taper of the lower anti-twist ring 162, the lower clamping through hole 1621 and the lower rotating reverse buckle 153 generate a self-tightening effect. The glue-free and chemical-solvent-free medical device transmission tube joint assembly 10 can be applied to scenarios such as the liquid transportation of a ventilator humidifying tank, the contrast agent delivery during CT, and the transportation of other blood or liquids and gases; through mechanical assembly, the volatilization of zero volatile organic compounds is realized, avoiding the use of volatile compounds such as chemical solvents and glue curing, and solving the problem that the transmission tube joint assembly in the prior art cannot be repeatedly sterilized at high temperature.

Thus, a firm connection of each component can be achieved without glue or chemical solvents. By sequentially arranging the upper anti-twist sleeve 11, the upper rotating buckle 12, the upper transmission joint 13, the lower rotating buckle 15 and the lower anti-twist sleeve 16 from top to bottom, a complete assembly connection structure is formed. The upper anti-twist sleeve 11 and the lower anti-twist sleeve 16 are respectively sleeved in the upper rotating buckle 12 and the lower rotating buckle 15, effectively preventing the relative rotation of the rotating buckle under the action of external force and ensuring the stability of the transmission tube joint.

[0056] Please refer to Figures 1 to 8 , in some embodiments, the size of the lower rotating shell 142 is adapted to the size of the upper transmission pipeline 1322, and the upper transmission pipeline 1322, the lower rotary buckle channel 1511 and the lower transmission pipeline 144 communicate with each other. Thereby ensuring the smooth transmission of the fluid inside the transmission pipe joint assembly. The size of the lower transmission pipeline 144 is adapted to the size of the upper transmission pipeline 1322, ensuring the continuity and stability of the fluid during transmission. At the same time, the mutual communication between the upper rotary buckle channel 1212, the upper transmission pipeline 1322, the lower rotary buckle channel 1511 and the lower transmission pipeline 144 forms a complete fluid transmission channel, ensuring that the fluid can be smoothly transmitted from one end to the other end. This design not only improves the transmission efficiency of the medical device, but also reduces the medical risks that may be brought about by unsmooth fluid transmission.

[0057] In some embodiments, the length of the upper transfer pipe 1322 is set to be 2.4 to 2.5 times the length of the upper make-up channel 1212, and the length of the lower transfer pipe 144 is set to be 3 to 3.5 times the length of the lower make-up channel 1511. Thus, pulse-free delivery of contrast agents and other high-viscosity liquids can be achieved through the uneven channel lengths.

[0058] Please refer to Figures 1 to 3 In some embodiments, when the external thread 1411 engages with the internal thread 1324, the upper transfer joint 13 is connected to the lower transfer joint 14. Thus, a tight connection between the upper transfer joint 13 and the lower transfer joint 14 is achieved through the engagement of the external thread 1411 and the internal thread 1324. The diameters of the upper make-up channel 1212 and the lower make-up channel 1511 are smaller than the diameters of the upper transfer pipe 1322 and the lower transfer pipe 144. This not only ensures the stability and fixing effect of the transfer pipe but also avoids fluid leakage or pressure loss caused by overly large channels. It not only improves the reliability and service life of the medical device but also reduces the safety risks that may be brought about by loose connections or leakage.

[0059] Please refer to Figure 9 In some embodiments, the upper anti-twist sleeve 11 includes an upper anti-twist body 111 and an upper anti-twist ring 112. The upper anti-twist body 111 is used to be sleeved on the upper make-up 12 to prevent the upper make-up 12 from rotating relative to the upper transfer joint 13 under the action of external force. The upper anti-twist ring 112 is disposed in the upper anti-twist body 111. The upper anti-twist ring 112 is used to cooperate with the reverse step to fasten the upper anti-twist sleeve 11. The upper anti-twist ring 112 has an upper clamping through-hole 1121, and the diameter of the upper clamping through-hole 1121 decreases sequentially from top to bottom. Thus, it effectively prevents the upper make-up 12 from rotating relative to the upper transfer joint 13 under the action of external force, thereby ensuring the stability and reliability of the assembly. At the same time, it also enhances the connection strength between the upper anti-twist sleeve 11 and the upper make-up 12.

[0060] Please refer to Figure 10, in some embodiments, the lower anti-twist sleeve 16 includes a lower anti-twist body 161 and a lower anti-twist ring 162. The lower anti-twist body 161 is used to be sleeved in the lower swivel 15 to prevent the lower swivel 15 from rotating relative to the lower transmission joint 14 under the action of an external force; the lower anti-twist ring 162 is arranged in the lower anti-twist body 161, and the lower anti-twist ring 162 is used to cooperate with the reverse buckle step to fasten the lower anti-twist sleeve 16. The lower anti-twist ring 162 has a lower clamping through hole 1621, and the aperture of the lower clamping through hole 1621 decreases sequentially from bottom to top. Furthermore, it effectively prevents the lower swivel 15 from rotating relative to the lower transmission joint 14 under the action of an external force, thus ensuring the stability and reliability of the assembly, and at the same time enhancing the connection strength between the lower anti-twist sleeve 16 and the lower swivel 15.

[0061] In some embodiments, a plurality of wavy protrusions with sequentially decreasing spacing from top to bottom are arranged in the upper curved convex part 1213 and the lower curved convex part 1513. Furthermore, the transmission pipe can generate bidirectional compressive deformation. When heated, the wavy protrusions will expand together with the upper curved convex part 1213 and the lower curved convex part 1513, enhancing the clamping force of the upper curved convex part 1213 and the lower curved convex part 1513 on the transmission pipe.

[0062] In summary, the present application provides a medical device transmission pipe joint assembly without glue and chemical solvents. The medical device transmission pipe joint assembly without glue and chemical solvents has: an upper anti-twist sleeve; an upper swivel, the upper anti-twist sleeve is sleeved at one end of the upper swivel; an upper transmission joint, the upper transmission joint has an upper socket end and an upper connection end arranged oppositely, and the other end of the upper swivel is connected to the upper socket end; a lower transmission joint, the lower transmission joint has a lower socket end and a lower connection end arranged oppositely, and the upper connection end is connected to the lower connection end; a lower swivel, one end of the lower swivel is connected to the lower socket end; a lower anti-twist sleeve, the lower anti-twist sleeve is sleeved at the other end of the lower swivel. Furthermore, it realizes the firm connection of each component without glue or chemical solvents. By sequentially arranging the upper anti-twist sleeve, the upper swivel, the upper transmission joint, the lower swivel and the lower anti-twist sleeve from top to bottom, a complete assembly connection structure is formed. The upper anti-twist sleeve and the lower anti-twist sleeve are respectively sleeved in the upper swivel and the lower swivel, effectively preventing the relative rotation of the swivels under the action of an external force and ensuring the stability of the transmission pipe joint. At the same time, the upper transmission joint and the lower transmission joint form a stable and easy-to-assemble joint assembly through the fastening action of the threads, not only avoiding the possible health risks caused by the volatilization of volatile organic compounds, but also solving the problem that the transmission pipe joint assembly in the prior art cannot be repeatedly sterilized at high temperature, meeting the high-standard safety requirements of medical devices.
