[0021] Referring to FIG. 1 , the first embodiment of the present application provides a puncture latch connector 10 for patient infusion. First, the conical puncture head can be inserted into a medication bag or vial to form a stable infusion channel. The oblique puncture holes 111 on the puncture head allow liquid to flow quickly into the infusion line, reducing the possibility of blockage. Second, the rectangular body 121 of the gripping part 12 provides a better gripping experience. The healthcare professional can control the angle and depth of the puncture latch connector through the gripping part 12, ensuring stability during the puncture process and reducing the risk of manipulation due to unstable gripping. Finally, one end of the connecting tube 13 is connected to the puncture head, and the other end is connected to the infusion tube 21 via the liquid discharge hole 131. After the conical puncture head 11 is inserted into the medication bag, liquid flows more smoothly into the infusion tube 21, ensuring the continuity and efficiency of the infusion process. In addition, the installation of the latch member 22 ensures a safe connection of the infusion tube 21 during the operation process, effectively preventing liquid leakage and improving the overall safety and reliability of use.

[0022] 2 to 5, in some embodiments, the puncture latch connector 10 is composed of a conical puncture head 11, a limit plate 14, a gripping portion 12, and a connecting tube 13, which are formed sequentially from top to bottom. The conical puncture head 11 has an oblique puncture hole 111, which makes the liquid inflow path smoother and reduces the possibility of blockage or liquid reflux. The limit plate 14 has a puncture end 141 and a gripping end 142 which are oppositely provided. The conical puncture head 11 is provided perpendicularly on the puncture end 141. The limit plate 14 is used to limit the displacement of the conical puncture head 11, which prevents the conical puncture head 11 from being displaced too far and prevents the conical puncture head 11 from puncturing too deeply or coming off. The gripping part 12 has a rectangular body 121, one end of which is perpendicular to the limit plate 14, and one end of the connecting tube 13 is fixed to the other end of the rectangular body 121. Compared with the conventional cylindrical gripping structure, this increases the friction when gripping, avoiding problems with slipping caused by sweaty hands or improper hand posture of medical personnel and ensuring a more stable and safer operation process. The other end of the connecting tube 13 is provided with a liquid discharge hole 131, which communicates with the oblique puncture hole 111, allowing for smoother liquid flow, improving infusion efficiency, reducing problems with gas stagnation and blockage, and further ensuring smooth infusion.

[0023] 2 to 5, in some embodiments, the rectangular body 121 has a first end surface 1211 and a second end surface 1212 opposite to each other, with a first gripping blade 1213 and a second gripping blade 1214 provided at the corners of the first end surface 1211, and a third gripping blade 1215 and a fourth gripping blade 1216 provided at the corners of the second end surface 1212, providing additional support points for the fingers, making gripping more comfortable and stable and reducing fatigue during long-term operation. Here, the first gripping blade 1213, the second gripping blade 1214, the third gripping blade 1215 and the fourth gripping blade 1216 are all perpendicular to the limit plate 14, making the force applied during gripping more uniform and avoiding the risk of loss of gripping control or partial slippage due to force at a single point, helping medical personnel to better control the use of the puncture head.

[0024] 2 to 5, in some embodiments, a first beveled groove 1217 is formed between the first and second gripping blades 1213 and 1214, a second beveled groove 1218 is formed between the third and fourth gripping blades 1215 and 1216, a third beveled groove 1219 is formed between the first and third gripping blades 1213 and 1215, and a fourth beveled groove 1220 is formed between the second and fourth gripping blades 1214 and 1216, thereby not only optimizing the design of the gripper 12 but also making the gripper structure lighter, increasing the contact area of fingers, and increasing friction, thereby greatly reducing the possibility of gripper slippage during operation.

[0025] 1 and 2, in some embodiments, the third groove 1219 is provided with an air inlet tube 1221, which is connected to the liquid discharge hole 131 and the oblique puncture hole 111, thereby effectively discharging gas from within the tube, preventing air bubbles from appearing during the infusion process, ensuring the continuity and stability of the liquid flow, and avoiding problems of poor or delayed infusion caused by gas blockage.

[0026] In some embodiments, the air inlet tube 1221 is provided with a waterproof and breathable membrane, allowing the air in the air inlet tube 1221 to flow through the air inlet holes in the air inlet tube 1221 and the waterproof and breathable membrane, and preventing the liquid from flowing out of the air inlet tube 1221, thereby maintaining the balance of air pressure during the liquid collection or infusion process, ensuring the continuity and stability of the liquid flow, and avoiding the problem of poor or delayed infusion caused by gas blockage.

[0027] Referring to Figures 2 to 5, in some embodiments, a number of reinforcing members 1222 are provided in both the third groove 1219 and the fourth groove 1220, providing a reinforcing support structure, which makes the grooves more stable when pressure is applied, prevents the groove openings from bursting or deforming due to excessive force, and ensures the reliability of the puncture operation.

[0028] Referring to FIG. 4, in some embodiments, the multiple reinforcing members 1222 may be cylindrical, ribbed, or spacer-shaped, and the structure of the reinforcing members 1222 can be adjusted as needed to further optimize the structural strength and pressure resistance of the puncture latch connector 10 and ensure the reliability of the puncture operation of the puncture latch connector 10.

[0029] 4 and 6, a second embodiment of the present application provides an infusion assembly 20 that does not use adhesives or chemical solvents, and the infusion assembly 20 that does not use adhesives or chemical solvents includes the above-mentioned puncture latch connector 10, an infusion tube 21, and a latch member 22, the connecting tube 13 includes a connecting tube body 132, a buckling plate 133, and a reverse buckling member 134, the buckling plate 133 is provided in a loop shape on the side of the connecting tube body 132 that is closer to the grip portion 12, and the reverse buckling member 134 is provided in a loop shape on the end of the connecting tube body 132 that is farther from the grip portion 12, the infusion tube 21 is detachably connected to the puncture latch connector 10, a puncture hole 222 is provided in the latch member 22, and the puncture hole 222 is secured to the connecting tube 21 by the latch member 22. 13, the puncture hole 222 is used for the infusion tube 21 to pass through, and the latch member 22 is used for fixing the infusion tube 21 onto the puncture latch connector 10, which greatly improves the airtightness and connection quality between the puncture latch connector 10 and the infusion tube 21, avoids the loosening problem caused by traditional adhesive connections, abandons the process of using and curing an adhesive, eliminates the safety risks caused by the evaporation of volatile organic substances, ensures patient safety, and does not require air-drying curing time, thereby reducing the manufacturing time and cost of the adhesive-free and chemical solvent-free infusion assembly and improving the production capacity of the adhesive-free and chemical solvent-free infusion assembly.

[0030] Referring to Figure 7, in some embodiments, the latch member 22 is formed as a swivel connector 221, and a number of swivel protrusions 2211 are provided on the inner wall of the swivel connector 221 facing the connecting tube 13, and a number of latch protrusions 1331 are provided on the buckling plate 133, each corresponding to a number of the swivel protrusions 2211, and swivel openings 1332 are opened in the number of the latch protrusions 1331, the size of the swivel openings 1332 is matched to the swivel protrusions 2211. The strong connection between the swivel protrusions 2211 and the swivel openings 1332 on the buckling plate 133 can avoid the phenomenon of leakage or disconnection caused by loose connection of the infusion tube 21 during the infusion process, and ensure the continuity and stability of the infusion. An anti-loosening protrusion 1333 is provided at the entrance of the swivel opening 1332, and the anti-loosening protrusion 1333 is used to prevent the swivel protrusion 2211 abutting against the swivel opening 1332 from loosening. Here, the infusion tube 21 passes through the puncture hole 222, the infusion tube 21 is socket-fitted into the connecting tube body 132, and the swivel protrusion 2211 abuts on the buckling plate 133, causing the swivel connector 221 to rotate, and a number of the swivel protrusions 2211 are screwed into the swivel opening 1332. This prevents the swivel protrusions 2211 from loosening due to twisting or pulling of the infusion tube 21 during the long-term infusion process, and improves overall safety in use.

[0031] Referring to Figure 8, in some embodiments, the latch member 22 is formed as a reverse buckling connector 23, and the reverse buckling connector 23 includes a number of clinch fasteners 2321, and a number of the clinch fasteners 2321 are provided on one end of the reverse buckling connector 23 away from the puncture hole 222, and the clinch fasteners 2321 include a deformation portion 2322 and a snap portion 2323, so that the reverse buckling connector 23 can be assembled quickly during the assembly process and at the same time the robustness and reliability of the connection can be greatly improved.

[0032] Referring to FIG. 8 , in some embodiments, a segment 2324, a side support segment 2326, and a snap-stop segment 2327 are integrally molded with the snap portion 2323, wherein the infusion tube 21 passes through the puncture hole 222, the infusion tube is socket-fitted into the connection tube body 132, the reverse buckling connector 23 is displaced toward the puncture latch connector 10, the abutment segment 2324 abuts against the buckling plate 133, and the deformation portion 2322 is biased outward. This drives the deformation portion 2322 to bend, and the side support segment 2326 abuts against the side wall of the buckling plate 133, snapping the snap-fastening segment 2327 onto the buckling plate 133. The cooperative action of the abutment segment 2324, the side support segment 2326 and the snap-fastening segment 2327 ensures a firm connection between the infusion tube 21 and the puncture latch connector 10 without loosening, further avoiding the risk of liquid leakage or device detachment during the infusion process.

[0033] Referring to Figure 9, in some embodiments, the infusion tube 21 can be directly inserted into the reverse buckling member 134, and then the infusion tube 21 can be socketed into the connecting tube body 132, thereby achieving an interference fit between the infusion tube 21 and the connecting tube body 132, thereby firmly connecting the infusion tube 21 and the puncture latch connector 10 without loosening, and further avoiding the risk of liquid leakage or device detachment during the infusion process.

[0034] In summary, the present application provides a puncture latch connector, an infusion assembly that does not use adhesives or chemical solvents, and the puncture latch connector is composed of a conical puncture head, a limit plate, a gripping portion, and a connecting tube, which are formed sequentially from top to bottom, the conical puncture head having an oblique puncture hole, the limit plate having a puncture end and a gripping end opposite to each other, the conical puncture head being vertically mounted on the puncture end, the limit plate being used to limit the displacement of the conical puncture head, the gripping portion having a rectangular body, one end of the rectangular body being connected to the limit plate.
