DETAILED DESCRIPTION

[0028] 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 described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0029] See also Figure 1-5 The utility model provides a technical solution: a flow regulator for an infusion tube with an alarm function, comprising a lower connecting block 1, an upper connecting block 2, a fixing column 3, a fixing ring 4, a fixing block 5, an adjusting mechanism 6, a movable column 7, an upper clamping rod 8, a lower clamping rod 9, a mounting plate 10, a spring 11, a movable block 12, a pull rod 13, a positioning column 14, a fixing hole 15 and an alarm 16.

[0030] When using the flow regulator for infusion tube with alarm function, if Figure 1 , Figure 2 and Figure 3As shown, the upper end of the lower connecting block 1 is rotatably connected to the upper connecting block 2, and an adjusting mechanism 6 is arranged between the lower connecting block 1 and the upper connecting block 2, and the adjusting mechanism 6 comprises a movable column 7 connected through the middle of the upper connecting block 2, an upper clamping rod 8 fixedly connected to the lower end of the movable column 7, and a lower clamping rod 9 fixedly connected to the inner wall of the lower connecting block 1. First, the infusion pipeline is placed in the middle of the lower connecting block 1, and the infusion pipeline is clamped in the lower clamping rod 9. Then, by rotating the fixed column 3, the fixed column 3 and the upper connecting block 2 are rotated, and at the same time, the torsion spring at the connection between the fixed column 3 and the upper connecting block 2 is generated. After elastic deformation, the fixing column 3 drives the fixing ring 4 to move, and then the upper connecting block 2 is turned over, and the upper connecting block 2 is rotated with the lower connecting block 1, so that the upper connecting block 2 is fitted and arranged on the upper end of the lower connecting block 1, and the lower connecting block 1 drives the upper clamping rod 8 to engage with the outside of the infusion tube, and then the fixing column 3 is loosened. At this time, the torsion spring at the connection between the fixing column 3 and the upper connecting block 2 restores the elastic deformation, driving the fixing column 3 and the upper connecting block 2 to rotate, so that the fixing column 3 drives the fixing ring 4 to engage with the fixing block 5, thereby facilitating the limit between the upper connecting block 2 and the lower connecting block 1;

[0031] During the infusion process, when the flow rate needs to be adjusted, Figure 2 , Figure 4 and Figure 5 As shown, by pulling the pull rod 13, the pull rod 13 moves with the mounting plate 10, and the pull rod 13 drives the movable block 12 to slide in the mounting plate 10, and the movable block 12 squeezes the spring 11, so that the spring 11 undergoes elastic deformation, and the movable block 12 drives the positioning column 14 to extend and retract at the upper end of the upper connecting block 2, so that the positioning column 14 is disengaged from the fixing hole 15, thereby releasing the limit between the movable column 7 and the upper connecting block 2, and then by pressing the movable column 7 downward, the movable column 7 slides with the upper connecting block 2, and the movable column 7 drives the upper clamping rod 8 to move, so that the upper clamping rod 8 squeezes the infusion tube, so that the infusion tube undergoes a certain deformation, thereby achieving the effect of controlling the flow rate of the liquid in the infusion tube and preventing the flow rate from being too fast;

[0032] When the adjustment is completed, the pull rod 13 is directly released. At this time, the spring 11 restores its elastic deformation, driving the movable block 12 to slide in the mounting plate 10, so that the movable block 12 drives the positioning column 14 to move, and the fixing holes 15 are arranged at equal intervals on the right end of the movable column 7. At this time, the positioning column 14 is engaged in the fixing holes 15 at the corresponding position, which is convenient for limiting the movable column 7 and the upper connecting block 2 to prevent the upper clamping rod 8 from loosening from the infusion tube, affecting the actual control effect, and an alarm 16 is fixedly installed on the upper left end of the upper connecting block 2. Through the setting of the alarm 16, when an emergency is needed, the button next to it can be directly pressed to sound an alarm through the alarm 16 to remind medical staff to pay attention.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
