[0032] like Figures 1-5 As shown, a PICC pipe cleaning device with a timed self-cleaning function includes a three-way valve 101, a control panel 102, a timer, and an electric actuator 119. The control panel 102 is located on one side wall of the three-way valve 101, and the electric actuator 119 is located on the other side wall of the three-way valve 101. The timer is connected to the electric actuator 119. The control panel 102 is equipped with a display 1021 and multiple buttons 1022. The timer's calculation duration, interval time, and the extension amount of the electric actuator 119 can be controlled by the buttons 1022. The relevant information is displayed on the display 1021. The piston rod of the electric actuator 119 is equipped with a locking block 104, and the locking block 104 is equipped with an arc-shaped groove.
[0033] The three-way connector 101 includes a first connector 1011, a second connector 1012 and a third connector 1013. The first connector 1011 is provided with a first partition 106 and a second partition 107. A gap is left between the first partition 106 and the second partition 107. The first partition 106 is provided with a first mounting hole, and the second partition 107 is provided with a first through groove 1071.
[0034] A connecting sleeve 110 is provided in the first mounting hole, and the connecting sleeve 110 is threaded into the first mounting hole; multiple rubber pads 113 are provided on the inner wall of the connecting sleeve 110, the rubber pads 113 are spindle-shaped and hollow; an end plate 1101 is provided at one end of the connecting sleeve 110, which limits the maximum position of the connecting sleeve 110 in the first mounting hole; a cavity is provided on the end plate 1101, and an air passage 1102 communicating with the connecting sleeve 110 is provided on the side wall of the cavity; a movable ring 114 is provided in the cavity, and a first return spring 1141 is provided on the movable ring 114, with one end of the first return spring 1141 abutting against the inner wall of the cavity.
[0035] The connecting sleeve 110 is fitted onto the syringe nipple. The rubber pad 113 increases the friction between the connecting sleeve 110 and the side wall of the syringe nipple. Then, the connecting sleeve 110 is connected to the mounting hole by a threaded connection, thereby connecting the syringe to the three-way connector 101 and ensuring the connection effect between the syringe and the three-way connector 101. When the connecting sleeve 110 is connected to the first mounting hole, the end plate 1101 abuts against the first partition 106, and the movable ring 114 moves into the cavity to squeeze the airflow into the rubber pad 113, causing the rubber pad 113 to expand, increasing the connection effect between the rubber pad 113 and the syringe nipple, and ensuring the stability of the syringe connection.
[0036] The second connector 1012 is provided with a third partition 108 and a fourth partition 109. The third partition 108 is provided with a second mounting hole, and the fourth partition 109 is provided with a second through groove 1091. The second mounting hole is also provided with a connecting sleeve 110. The first through groove 1071 and the second through groove 1091 are staggered.
[0037] The second partition 107 is provided with a first baffle 115, and the fourth partition 109 is provided with a second baffle 116. The first baffle 115 and the second baffle 116 are connected by a first connecting rod 117. The three-way connector 101 is provided with a mounting rod 111, which is provided with a guide groove. The first connecting rod 117 is provided with a guide rod 112, which is inserted into the guide groove. One end of the guide rod 112 is provided with a second return spring 120, and an electromagnet 121 is provided in the guide groove. One end of the guide rod 112 is provided with a magnetic block.
[0038] When the electromagnet 121 is not energized, the guide rod 112 extends out of the guide groove, the first baffle 115 is located on one side of the first through groove 1071 and closes the first through groove 1071, and the second baffle 116 is offset from the second through groove 1091 so that the second through groove 1091 is open; when the electromagnet 121 is energized, it generates a magnetic force that attracts the magnetic block, and the electromagnet 121 attracts the guide rod 112 to move into the guide groove. The guide rod 112 drives the first baffle 115 and the second baffle 116 to move. The first baffle 115 is offset from the first through groove 1071 so that the first through groove 1071 is open, and the second baffle 116 is located on one side of the second through groove 1091 and closes the second through groove 1091.
[0039] The three-way valve 101 has a mounting block 103 on its side wall. An electric actuator 119 is mounted on the mounting block 103. A connecting block 105 is mounted on the piston rod of the electric actuator 119. A second connecting rod 118 is mounted on the locking block 104. The second connecting rod 118 is connected to the connecting block 105. The connecting block 105 has a threaded groove. The second connecting rod 118 is inserted into the threaded groove. The side wall of the second connecting rod 118 has an external thread. The locking block 104 is rotatably connected to the second connecting rod 118. By engaging the external thread on the second connecting rod 118 with the threaded groove on the connecting block 105, the position of the locking block 104 can be adjusted, allowing the locking block 104 to adapt to syringes of various lengths.
[0040] When connecting the syringe, first put the connecting sleeve 110 onto the nipple of the syringe, and connect the connecting sleeve 110 to the three-way connector 101 through the thread. Adjust the position of the locking block 104 according to the length of the syringe so that the arc-shaped groove is locked on the piston of the aspiration syringe. Use the control panel 102 to set the working interval of the electric push rod 119. The electromagnet 121 works in conjunction with the electric push rod 119 to automatically complete the thrombolysis operation at a timed interval.
[0041] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
