[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-2 In one embodiment of this utility model: the bottom of the adapter head 2 is fixedly connected to the outer shell 1, the bottom of the outer shell 1 is fixedly connected to the telescopic tube 3, the bottom of the telescopic tube 3 is fixedly connected to the reinforcing tube 4, the inner wall of the adapter head 2 is fixedly connected to the first interface 9, the second interface 10, the third interface 11 and the fourth interface 12, the inner wall of the adapter head 2 is fixedly connected to the cable placement channel 14, the bottom of the adapter head 2 is fixedly connected to the connection channel 15, and the inner wall of the outer shell 1 is provided with a cable gathering area 16.

[0025] The adapter 2 achieves multi-channel connection through the first interface 9, the second interface 10, the third interface 11, and the fourth interface 12 on its inner wall. The cable management channel 14 on the inner wall of the adapter 2 performs initial cable organization, and the connection channel 15 at the bottom of the adapter 2 guides the organized cables into the housing 1. The cable management area 16 on the inner wall of the housing 1 centrally stores and organizes the cables, preventing them from becoming messy and tangled. The telescopic tube 3 fixed at the bottom of the housing 1 allows for flexible adjustment of the device length to adapt to different usage scenarios. The reinforcing tube 4 at the bottom of the telescopic tube 3 enhances the overall structural stability of the device, reduces the impact of external forces on the internal cables and interfaces, and ensures stable transmission through the coordinated operation of all components.

[0026] Reference Figures 1-2 The bottom of the reinforcing tube 4 is fixedly connected to a protective sleeve 5, the bottom of the protective sleeve 5 is fixedly connected to a connecting shell 21, and the top of the connecting shell 21 is fixedly connected to an anti-slip ring 6.

[0027] The protective sleeve 5, fixed to the bottom of the reinforcing tube 4, further encloses the internal connection structure, forming an additional protective barrier to reduce the intrusion of external dust and contaminants. It also buffers against physical impacts such as collisions and friction, preventing damage to internal components. The connecting shell 21 at the bottom of the protective sleeve 5 provides a support base for subsequent connecting components, ensuring the structural integrity of the connection area. The anti-slip ring 6 on the top of the connecting shell 21 increases friction with the mounting surface or when gripped, improving the stability of the device after installation, preventing displacement due to vibration during use, and making it easier for medical personnel to grip and control during operation, facilitating precise docking operations and ensuring the overall stability of the connection and transmission.

[0028] Reference Figure 5 A fixed tube 19 is slidably connected to the inner wall of the connecting shell 21. There are two protruding buttons 7 on both sides of the inner wall of the fixed tube 19. A connecting block 18 is slidably connected to one side of the protruding button 7. A spring 17 is fixedly connected to one end of the connecting block 18.

[0029] The inner wall of the connecting shell 21 and the fixing tube 19 form a sliding fit, allowing the position of the fixing tube 19 to be adjusted according to docking requirements and adapt to different connection scenarios. Two protruding buttons 7 on the inner walls of both sides of the fixing tube 19 cooperate with the connecting block 18. A spring 17 fixed to one end of the connecting block 18 provides elastic force. When an external connector is inserted, the spring 17 is compressed, causing the connecting block 18 and the protruding buttons 7 to move together, clamping and limiting the inserted connector. The elastic return characteristic of the spring 17 ensures that the protruding buttons 7 always maintain a stable clamping position on the interface, preventing loosening or detachment during connection. Simultaneously, the sliding structure adapts to the insertion depth of connectors of different specifications, ensuring the tightness and stability of the connection and facilitating smooth transmission.

[0030] Reference Figure 5 The bottom of the fixed tube 19 is rotatably connected to the connector 8.

[0031] The bottom of the fixed tube 19 is connected to the connector 8 by a rotating method, which can flexibly adjust the orientation angle of the connector 8 to adapt to different installation positions and docking requirements, avoid the line being pulled due to angle limitation, ensure the stability of the connection part, and help the transmission function to be realized smoothly.

[0032] Reference Figure 5 The inner wall of connector 8 is fixedly connected to output port 20.

[0033] The output port 20, fixed on the inner wall of connector 8, serves as the core transmission interface, receiving signals or fluids transmitted through the fixed tube 19. Through precise fitting with external adapter components, stable docking is achieved, ensuring the smoothness and reliability of multi-path transmission.

[0034] Reference Figure 4 The adapter head 2 has an internal fixed connection with an air hole 13.

[0035] The internal air holes 13 of the adapter head 2 form a ventilation channel, accelerate the internal air circulation, dissipate heat and remove moisture in time, avoid damage to components due to moisture or overheating, and ensure stable operation of the device.

[0036] Reference Figure 5 The other side of the spring 17 is fixedly connected to the inner wall of the fixed tube 19.

[0037] The other side of the spring 17 is fixed to the inner wall of the fixed tube 19, forming a stable support point, providing a continuous elastic force to the connecting block 18, ensuring that the convex button 7 always clamps the joint, avoiding loosening of the connection, and ensuring docking stability.

[0038] Working Principle: This medical connector protective device achieves stable protection and transmission functions through the coordinated operation of various structures. The first interface 9, second interface 10, third interface 11, and fourth interface 12 on the inner wall of the adapter head 2 accommodate multi-path connection needs. The cable guide 14 initially organizes the cables, and the connection channel 15 guides the cables to the cable management area 16 on the inner wall of the outer shell 1 for centralized storage, preventing cable tangling. The telescopic tube 3 at the bottom of the outer shell 1 allows for flexible adjustment of the device length. The reinforcing tube 4 at the bottom of the telescopic tube 3 enhances the overall structural stability, and the protective sleeve 5 at the bottom of the reinforcing tube 4 forms a protective barrier, reducing contaminant intrusion and physical impact. The connecting outer shell 21 at the bottom of the protective sleeve 5 provides a sliding mounting base for the fixing tube 19, and the anti-slip ring 6 at the top of the connecting outer shell 21 increases friction and improves installation stability. The protruding buttons 7 on both sides of the inner wall of the fixing tube 19 cooperate with the connecting block 18. The spring 17 at one end of the connecting block 18 is fixed to the inner wall of the fixing tube 19, providing elastic force to achieve connector clamping and limiting. The connector 8, which is rotatably connected to the bottom of the fixed tube 19, can be adjusted in orientation, and its inner wall output port 20 enables precise docking and transmission with external components. The air vents 13 inside the adapter head 2 accelerate air circulation, dissipate heat and expel moisture, ensuring the long-term stable operation of all components of the device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
