When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
[0028] like Figures 1 to 4 As shown, in this embodiment, the utility model includes an infusion pump 1, a tube groove 2 and two displacement detection components 3, an infusion tube 5 is arranged in the tube groove 2, the infusion pump 1 abuts against the outer side of the infusion tube 5 through an extrusion component 6, and the two displacement detection components 3 are respectively located on both sides of the infusion pump 1, and both abut against the outer side of the infusion tube 5.
[0029] For the sake of convenience of explanation, the infusion tube 5 is divided into a first pipeline 51, an intermediate pipeline 52 and a second pipeline 53 which are connected in sequence, the extrusion component 6 abuts against the intermediate pipeline 52 of the infusion tube 5, and the two displacement detection components 3 abut against the first pipeline 51 and the second pipeline 53 of the infusion tube 5 respectively; specifically, by setting up two displacement detection components 3 respectively located on both sides of the infusion pump 1, the parameters of the first pipeline 51 and the second pipeline 53 of the infusion tube 5 when moving can be respectively detected.
[0030] When the infusion tube 5 moves forward as a whole, the first pipeline 51 and the second pipeline 53 of the infusion tube 5 both move forward by the same stroke, so that the two displacement detection components 3 both detect the same parameters; in this case, the infusion tube 5 will not cause abnormal infusion accuracy, and no processing is required;
[0031] When the infusion tube 5 moves backward as a whole, the first pipeline 51 and the second pipeline 53 of the infusion tube 5 both move backward by the same stroke, so that the two displacement detection components 3 both detect the same parameters; in this case, the infusion tube 5 will not cause abnormal infusion accuracy, and no processing is required;
[0032] When the front section (second pipeline) of the infusion tube 5 retracts, the first pipeline 51 of the infusion tube 5 does not move, and the second pipeline 53 moves backwards by a certain stroke, which will cause the squeezed part of the middle pipeline 52 of the infusion tube 5 to be twisted, so that the squeezing component 6 cannot fully squeeze the middle pipeline 52 of the infusion tube 5, which will cause the infusion speed to be significantly reduced under the same peristaltic speed, and the infusion accuracy to be abnormal; wherein, there is a difference between the parameter detected by the displacement detection component 3 for detecting the second pipeline 53 and the parameter detected by the displacement detection component 3 for detecting the first pipeline 51, and when the difference is greater than the preset value, there is an abnormal infusion accuracy, and intervention is required for this situation;
[0033] When the front section (second pipeline) of the infusion tube 5 moves forward, the first pipeline 51 of the infusion tube 5 does not move, and the second pipeline 53 moves forward a certain distance, which will cause the squeezed part of the middle pipeline 52 of the infusion tube 5 to be elongated, resulting in a decrease in the amount of liquid inflow, which will cause the infusion speed to be significantly reduced under the same peristaltic speed, and the infusion accuracy to be abnormal; wherein, there is a difference between the parameter detected by the displacement detection component 3 for detecting the second pipeline 53 and the parameter detected by the displacement detection component 3 for detecting the first pipeline 51, and when the difference is greater than the preset value, there is an abnormal infusion accuracy, and intervention is required for this situation;
[0034] When the rear section (first pipeline) of the infusion tube 5 moves forward, the first pipeline 51 of the infusion tube 5 moves forward a certain distance, and the second pipeline 53 does not move, which will cause the squeezed part of the middle pipeline 52 of the infusion tube 5 to be twisted, causing the squeezing component 6 to be unable to fully squeeze the middle pipeline 52 of the infusion tube 5, resulting in a significant decrease in the infusion speed and abnormal infusion accuracy under the same peristaltic speed; wherein, there is a difference between the parameter detected by the displacement detection component 3 for detecting the second pipeline 53 and the parameter detected by the displacement detection component 3 for detecting the first pipeline 51, and when the difference is greater than the preset value, there is an abnormal infusion accuracy, and intervention is required in this situation;
[0035] When the rear section (first pipeline) of the infusion tube 5 retracts, the first pipeline 51 of the infusion tube 5 moves backward for a certain distance, and the second pipeline 53 does not move, which will cause the squeezed part of the middle pipeline 52 of the infusion tube 5 to be elongated, resulting in a decrease in the amount of liquid inflow, which will cause the infusion speed to be significantly reduced under the same peristaltic speed, and the infusion accuracy to be abnormal; wherein, there is a difference between the parameter detected by the displacement detection component 3 for detecting the second pipeline 53 and the parameter detected by the displacement detection component 3 for detecting the first pipeline 51, and when the difference is greater than the preset value, there is an abnormal infusion accuracy, and intervention is required in this situation;
[0036] With respect to the deficiencies of the prior art, in the present invention, two displacement detection components 3 are used to respectively detect the movement parameters of the tube body at the two sections before and after the squeezed part of the infusion tube 5 to determine whether there is an abnormality in the infusion accuracy, so as to identify the abnormal position of the pipeline occurring during the infusion process, thereby improving the reliability of the infusion pump used clinically, so that the present invention has the advantage of being able to detect abnormal position of the pipeline.
[0037] like Figures 4 to 5 As shown, in some embodiments, the displacement detection component 3 includes an angle sensor 7 and a gear 8, the angle sensor 7 is connected to the gear 8, and the gear 8 abuts against the outer side of the infusion tube 5. Specifically, the gear 8 is fitted to the outer side of the infusion tube 5, so that the gear 8 can be driven to rotate when the infusion tube 5 moves, and the rotation angle of the gear 8 is detected by the angle sensor 7, so that the infusion tube 5 can be detected when it moves forward or backward, so as to realize real-time detection of abnormal position of the infusion tube;
[0038] It should be noted that when the moving strokes of the first pipeline 51 and the second pipeline 53 of the infusion tube 5 are the same, the rotation angles detected by the two angle sensors 7 are the same, and the infusion is normal at this time; when the moving strokes of the first pipeline 51 and the second pipeline 53 of the infusion tube 5 are different, the difference in the rotation angles detected by the two angle sensors 7 is greater than a preset value (such as 30 degrees); at this time, the infusion tube 5 has an abnormal displacement problem, resulting in abnormal infusion, and intervention is required for corresponding processing.

[0041] like Figure 4 As shown, in some embodiments, the extrusion assembly 6 includes a plurality of paddles 16 , and the plurality of paddles 16 are arranged in sequence along the length direction of the tube groove 2 .
[0042] like Figure 7 As shown, in some embodiments, the infusion pump pipeline displacement detection device further includes an MCU module 17, and the two displacement detection components 3 are electrically connected to the MCU module 17, and the MCU module 17 is electrically connected to an alarm 18. Specifically, the MCU module 17 electrically connected to the two displacement detection components 3 continuously collects real-time data of the sensor, and when the difference detected by the two displacement detection components 3 is greater than a preset value and there is an abnormal infusion accuracy, the infusion is stopped at this time, and then an alarm is issued to the operator through the alarm 18, so as to perform corresponding processing on the abnormal state and ensure the safety of the infusion process.
