[0026] The working principle and use process of the utility model are as follows: when using the portable PICC nursing flushing device, first control the motor 12 to drive the screw 13 to rotate, so that the connecting rod 143 moves the piston 142 to the bottom of the cylinder 141, and the outlet end of the connecting tube 144 is filled with a bottle of saline solution, and the motor 12 is controlled to drive the screw 13 to rotate, so that the connecting rod 143 moves the piston 142 to the top of the cylinder 141, and the saline solution is sucked into the cylinder 141. If the flushing device body 1 is directly held to flush the tube, the connecting tube 144 can be directly connected to the patient's PICC tube port. If the box body 21 and the box cover 22 are combined into a bracket, the flushing device body 1 is placed on the C-shaped buckle 25 for automatic flushing, and the patient's PICC tube is connected through the extension tube 4. Before connecting the PICC tube, the piston 142 needs to be moved down a short distance to extend the extension tube 4. After the air in the tube 4 is exhausted, when flushing the tube, the operator can manually control the rotation of the motor 12 through the button on the control module 16, thereby controlling the movement of the piston 142 and manually performing the flushing operation. The operator can also place the main body 1 of the flushing device on the bracket composed of the box body 21 and the box cover 22, start the control module 16, and let the control module 16 control the intermittent movement of the piston 142 to automatically perform the flushing operation. During the use of the main body 1 of the flushing device, the charging module 24 can be connected to the charging module 24 by the charging cable 3, and the charging module 24 can charge the charging module 24, thereby improving the battery life of the main body 1 of the flushing device. When carrying the main body 1 of the flushing device, buckle the shell of the main body 1 of the flushing device onto the C-shaped buckle 25 on the box cover 22, and then cover the box cover 22 on the box body 21 with the front side facing up, so that the main body 1 of the flushing device can be stored in the box body 21, which is convenient for overall carrying.
