The infusion tube connector 100 provided by one embodiment of the utility model includes a first connector 10, a second connector 20 and a connector 30. The first connector 10 is connected to the infusion bottle of the infusion set; the second connector 20 is connected to the infusion pipeline of the infusion set; the connector 30 includes a first connecting end 31 and a second connecting end 32, the first connector 10 is connected to the connector 30 through the first connecting end 31, and the second connector 20 is connected to the connector 30 through the second connecting end 32; wherein, when the first connector 10 and the second connector 20 are in the connector 30, the first connector 10 and the second connector 20 are connected.

[0031] In this embodiment, the infusion tube connector 100100 can be used to transmit liquid medicine.

[0032] Among them, the first connector 10 is mainly used to connect the interface between the infusion bottle or infusion bag and the infusion pipeline. It serves as the outlet of the infusion bottle or infusion bag, and the liquid is transported to the infusion pipeline through the first connector 10. The first connector 10 usually has a hollow pipeline, which can be connected to the cannula of the second connector 20 to form an unobstructed liquid channel. The first connector 10 can be disassembled so that the infusion bottle or infusion bag can be easily replaced and connected to different infusion sets or infusion pipelines. The second connector 20 is mainly used to connect the interface between the infusion pipeline or infusion set and the first connector 10. It serves as the outlet of the infusion pipeline or infusion set, and the liquid is transported to the patient's body through the second connector 20. The second connector 20 usually has a cannula that can be inserted into the pipeline of the first connector 10 and connected thereto. The second connector 20 has the characteristic of being detachable, so that the infusion set or infusion pipeline can be easily replaced and connected to different infusion bottles or infusion bags. Through the second connector 20, the liquid can smoothly flow into the patient's body for infusion therapy.

[0033] In this embodiment, the first joint 10 is connected to one end of the connector 30, so that the first joint 10 can be fixed in the connector 30. And the second joint 20 is inserted into the connector 30 through the other end of the connector 30 and connected to the first joint 10. Through such a setting, the second joint 20 and the first joint 10 can be connected relatively easily, and the connector 30 fixes the first joint 10 and the second joint 20, which can prevent the first joint 10 and the second joint 20 from shaking, thereby preventing the first joint 10 and the second joint 20 from leaking due to the gap formed after shaking.

[0034] In some embodiments, the interior of the connector 30 is hollow to form a housing chamber 33, and the first connector 10 and the second connector 20 are accommodated in the housing chamber 33. By placing the first connector 10 and the second connector 20 in the housing chamber 33 of the connector 30, the interference of the external environment on the connection can be reduced, and pollutants can be prevented from entering the first connector 10 and the second connector 20 and affecting the sealing. In addition, the housing chamber 33 can also provide additional protection to prevent damage or loosening of the first connector 10 and the second connector 20. In addition, the connector 30 can also keep the relative position of the first connector 10 and the second connector 20 stable, prevent the first connector 10 and the second connector 20 from moving or rotating during the connection process, and ensure the firmness of the connection. At the same time, the space in the housing chamber 33 can accommodate a certain amount of liquid or gas, which helps to provide pressure balance and further increase the sealing of the connection.

[0035] In some embodiments, the first connector 10 includes a first connecting pipe 11, and the second connector 20 includes a second connecting pipe 21. When the first connector 10 and the second connector 20 are both located in the accommodating cavity 33, the first connecting pipe 11 is inserted into the second connecting pipe 21. When the first connector 10 and the second connector 20 are both located in the accommodating cavity 33 of the connector 30, the first connecting pipe 11 can be inserted into the second connecting pipe 21 to form a complete liquid channel. The firmness and sealing of the connection can be ensured to prevent liquid leakage or contamination. At the same time, by inserting the connecting pipe, the loosening or movement of the connector can be effectively prevented, and the stability of the connection can be maintained. Through such a setting, the drug solution can flow from the first connecting pipe 11 into the second connecting pipe 21 to achieve the purpose of infusion.

[0036] In some embodiments, the outer circumference of the second connecting pipe 21 is provided with an external thread 211, and the end of the accommodating chamber 33 close to the second connecting pipe 21 is provided with an internal thread 331, and the second connecting pipe 21 is threadedly connected to the accommodating chamber 33. The outer circumference of the second connecting pipe 21 is provided with an external thread 211, and the end of the accommodating chamber 33 close to the second connecting pipe 21 is provided with an internal thread 331, and the second connecting pipe 21 is threadedly connected to the accommodating chamber 33. The firmness and sealing of the connection can be increased by using a threaded connection. The cooperation of the external thread 211 and the internal thread 331 can fix the second connecting pipe 21 in the accommodating chamber 33 to prevent it from loosening or falling off. The threaded connection can also provide additional sealing and reduce the risk of liquid leakage.

[0037] Specifically, during the connection process, by rotating the second connecting pipe 21, the external thread 211 and the internal thread 331 can be locked with each other, and tightened while applying a moderate force. Compared with the case where no connecting member 30 is provided, a greater force is required to connect the first connector 10 and the second connector 20. In this embodiment, only a moderate force needs to be applied to connect the second connector 20 with the connecting member 30, and then the first connector 10 is inserted into the connecting member 30 to achieve the connection between the first connector 10 and the second connector 20, which saves time and effort.

[0038] In some embodiments, the external thread 211 includes a clamping groove 212, and the internal thread 331 includes a clamping protrusion 332. When the second connecting pipe 21 is threadedly connected to the accommodating chamber 33, the clamping protrusion 332 is tightly connected to the clamping groove 212. The bite action between the clamping protrusion 332 and the clamping groove 212 can increase the firmness and sealing of the connection. The design shape of the clamping protrusion 332 and the clamping groove 212 can make them bite each other when connected to form a tighter connection. This can prevent the connection from loosening or falling off and provide better sealing.

[0039] Specifically, when the threaded connection is performed, the clamping protrusion 332 is correctly inserted into the clamping groove 212, and they are engaged with each other by rotating or twisting. Through appropriate strength, the clamping protrusion 332 and the clamping groove 212 form a firm connection to ensure the stability and sealing of the connection.

[0040] In some embodiments, a first abutting protrusion 111 is provided on the outer peripheral side of the first connecting pipe 11, and a second abutting protrusion 333 is provided on the side of the accommodating cavity 33 close to the first connecting pipe 11. The first abutting protrusion 111 and the second abutting protrusion 333 abut against each other. The tightness and sealing of the connection can be ensured by the abutment between the first abutting protrusion 111 and the second abutting protrusion 333. When the first connecting pipe 11 is inserted into the accommodating cavity 33, the first abutting protrusion 111 abuts against the second abutting protrusion 333, forming a locking effect to prevent the connection between the first joint 10 and the connecting member 30 from loosening or falling off.

[0041] In some embodiments, the second abutting protrusion 333 includes a guide surface 3331 and a second abutting surface 3332 , and the guide surface 3331 is inclined toward the second abutting surface 3332 to guide the first abutting protrusion 111 to move toward the second abutting surface 3332 .

[0042] By the inclined setting of the guide surface 3331, the first abutting protrusion 111 can be guided to move toward the second abutting surface 3332 during the insertion process. The inclined shape of the guide surface 3331 can provide a guiding force so that the first abutting protrusion 111 is correctly oriented toward the second abutting surface 3332 when inserted into the accommodating cavity 33. Through such a setting, it can be ensured that the first abutting protrusion 111 is correctly aligned and abuts against the second abutting surface 3332 during the insertion process. In this way, the accuracy and stability of the connection between the first joint 10 and the connector 30 can be increased, and the sealing and reliability of the connection can be ensured.

[0043] In some embodiments, the first abutting protrusion 111 includes a first abutting surface 1111, and the first abutting surface 1111 and the second abutting surface 3332 are arranged in parallel with each other. When the first abutting protrusion 111 and the second abutting protrusion 333 abut each other, the first abutting surface 1111 and the second abutting surface 3332 abut each other. By making the first abutting surface 1111 and the second abutting surface 3332 arranged in parallel, it can be ensured that they can match each other and form a close contact during the abutting process. In the process of the abutting protrusions abutting each other, the first abutting surface 1111 and the second abutting surface 3332 will contact and abut each other. The first abutting surface 1111 and the second abutting surface 3332 can provide a more secure connection, prevent the connection from loosening or falling off, and ensure the sealing of the connection.
