[0013] In the figure: 1. joint; 2. pipe; 3. fixing groove; 4. interface; 5. fixing pin; 6. auxiliary installation strip; 7. groove; 8. anti-slip layer. DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1 The utility model provides a technical solution for an extracorporeal circulation pipeline connector: an extracorporeal circulation pipeline connector, comprising a connector 1 and a pipeline 2, a top end of the connector 1 is provided with an interface 4, two pairs of fixing grooves 3 are provided on the outer wall surface of the connector 1, a pair of fixing pins 5 are fixedly installed on the inner wall surface of the end of the pipeline 2, a pair of auxiliary strips 6 are relatively installed on the outer wall surface of the end of the fixing pin 5, a groove 7 is opened on the outer wall surface of the pair of auxiliary strips 6, and an anti-slip layer 8 is fixedly installed in the groove 7.

[0016] Furthermore, the installation aid strip 6 adopts a strip structure, and the anti-slip layer 8 is provided with a plurality of anti-slip stripes.

[0017] Furthermore, the fixing groove 3 and the fixing pin 5 are both annular structures.

[0018] Furthermore, the cross-sections of the fixing groove 3 and the fixing pin 5 are both triangular structures, and the fixing groove 3 and the fixing pin 5 cooperate with each other.

[0019] Furthermore, the interface 4 is configured as a sloped structure, and the pointed portion of the interface 4 is provided with an arc chamfer.

[0020] Furthermore, the auxiliary installation strip 6 is made of a hard plastic structure.

[0021] Embodiment: When the device is in use, the installation strip 6 on the pipe 2 is held by the hand, and the fingertips fit the anti-slip layer 8 in the groove 7 to increase the friction between the finger and the pipe 2, which prevents slipping and facilitates the insertion of the pipe 2 into the connector 1.

[0022] When the end of the pipe 2 is inserted into the joint 1, the interface 4 adopts a bevel structure and is provided with a curved chamfer at the tip. The tip of the interface 4 first enters the pipe 2 and gradually widens and deforms the pipe 2 along the bevel to facilitate installation.

[0023] When the end of the pipe 2 is pushed onto the joint 1, the fixing pin 5 is in close contact with the outer wall of the joint 1 and deforms. When the fixing pin 5 moves to the fixing groove 3, the fixing pin 5 is reset and enters the fixing groove 3, forming a certain limiting effect.

[0024] Since the installation aid strip 6 is made of a hard plastic structure, when the end of the pipe 2 is pushed into the connector 1, the end of the pipe 2 can be kept parallel to the connector 1 to prevent the pipe 2 from curling and affecting the installation.

[0025] After the installation, the pipe 2 is fixed under the limiting effect of the fixing groove 3 and the fixing pin 5. When it needs to be disassembled, the pipe 2 can be pulled out from the connector 1 by holding the auxiliary assembly strip 6.

[0026] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any such actual relationship or order between these entities or operations.
