[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, a disposable medical flushing connection tube includes a tube body; a pressure-controlling tube sleeve 2 is installed on the outside of the tube body 1, and the top end of the pressure-controlling tube sleeve 2 is connected to the screw sleeve 7 through the tube sleeve joint 5, and the screw sleeve 7 is screwed with the stud 4, and the stud 4 is installed in the notch of the middle section of the hand-held sleeve 3, and the stud 4 is hollow. The tube body 1 extends along the stud 4 and the hand-held sleeve 3; the pressure-controlling tube sleeve 2 is an inverted conical structure as a whole; the inner wall of the extrusion layer 6 is a slope structure, and the slope angle of the extrusion layer 6 is consistent with the inclination angle of the outer wall of the pressure-controlling tube sleeve 2. Among them, the pressure-controlling tube sleeve 2 installed on the outside of the tube body 1 belongs to a conical sleeve structure, and the tube body 1 is inserted into the hand-held sleeve 3, the pressure-controlling tube sleeve 2 and the stud 4. The overall structure is installed as a whole, and the stud 4 is fixedly installed inside the groove of the hand-held sleeve 3, and the screw sleeve 7 is used to drive the integrally connected pressure-controlling tube sleeve 2 to complete the regulation process of feeding into the groove. Moreover, the pressure control sleeve 2 is an inverted conical structure and cooperates with the extrusion layer 6 to complete the process of gradually increasing the water pressure. On the contrary, after loosening the screw sleeve 7 outward, the water pressure can be gradually reduced. The real-time positioning structure of the screw sleeve 7 can stabilize the water pressure. Compared with the process of adjusting the water pressure by hand, the pressure control is more accurate.

[0021] The inner wall of the groove of the hand-held sleeve 3 is provided with an extrusion layer 6, which is in extrusion contact with the pressure control sleeve 2, and the inner wall of the pressure control sleeve 2 is in extrusion contact with the tube body 1. The inclined surface structure of the extrusion layer 6 can also further adjust the water pressure inside the tube body 1.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the inner wall of the pressure control sleeve 2 is evenly distributed with inner rings 9, the outer wall of the inner ring 9 is in compression contact with the pipe body 1, and a deformation cavity 10 is retained inside the inner ring 9. Among them, a plurality of groups of inner rings 9 are evenly distributed on the inner wall of the pressure control sleeve 2, and the evenly distributed arrangement of the inner rings 9 evenly distributes the pressure to the outer wall of the pipe body 1.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the groove of the hand-held cover 3 is provided with a packaging layer 8 along the root of the stud 4. The packaging layer 8 enhances the overall structural strength.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the outer wall of the hand-held sleeve 3 extending along the groove is inclined at a certain angle, and the thickness of the extended outer wall gradually decreases. The structure of gradually decreasing outer wall thickness can prevent the tube body 1 from being unable to be removed due to overall structural contraction or unexpected conditions.

[0025] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
