The pressure sensor is disposed at the matching position of the pump body 10 and the medicine box 30, so that the pressure sensor can abut against the output tube 202 when the medicine box 30 is mounted on the pump body 10.
By arranging the pressure sensor, when the liquid in the infusion bag 201 is used up, the pressure of the liquid in the output pipe 202 is reduced, and the abnormality of too low pressure occurs; when the output tube 202 is clogged or the infusion speed is too fast, and the pressure of the liquid in the output tube 202 is too high, an abnormality of too high pressure occurs. The processor 21 obtains the abnormality of the over-high or over-low pressure through the pressure sensor, and transmits the abnormality to the remote terminal 203 through the remote transmission module 23, so that the medical staff can find the abnormality in time, obtain the position where the abnormality occurs through the positioning module 22, perform corresponding processing, adjust the infusion speed or stop the infusion, and ensure a safe infusion process.
Optionally, when the processor 21 finds that the pressure is abnormal, the alarm device may be triggered to let the user and the medical staff know the abnormal condition at the same time, so that the user can adjust the infusion speed or stop the infusion by himself/herself before the medical staff arrives. And the medical staff can find the position of the abnormal infusion device more quickly according to the sent alarm signal.
In order to monitor the infusion state, as shown in fig. 5, an output tube 202 for communicating the infusion bag 201 with an external infusion tube is disposed in the drug box 30, as shown in fig. 3 and 6, the control module 20 further includes a bubble detection module 25, the bubble detection module 25 includes a first sensor electrically connected to the processor 21, the first sensor is disposed at a matching position of the pump body 10 and the drug box 30, and the first sensor is configured to correspond to the output tube 202 to detect bubbles in the liquid in the output tube 202. The first sensor may be an ultrasonic sensor or an infrared sensor or other sensor capable of detecting air bubbles in the output tube 202, as the present disclosure is not limited thereto.
Through setting up first sensor, when the bubble in the output tube 202 was too much when unusual, treater 21 can acquire this bubble too much unusual through first sensor to transmit this unusual to remote terminal 203 through teletransmission module 23, thereby can let medical personnel in time discover this unusual, acquire the position that appears unusually through orientation module 22, and make corresponding processing, adjust infusion speed or stop the infusion, with the infusion process of guaranteeing safety. And the medical staff can find the position of the abnormal infusion device more quickly according to the sent alarm signal.
Optionally, when the processor 21 finds that the bubbles are too much abnormal, the processor may trigger the alarm device to let the user and the medical staff know the abnormal condition at the same time, so that the user may adjust the infusion speed or stop the infusion by himself/herself before the medical staff arrives.
In order to monitor the motion state of the portable infusion device 100, as shown in fig. 4 and 6, the control assembly 20 further comprises a motion state detection module 26, the motion state detection module 26 comprises a second sensor for detecting the motion state of the portable infusion device 100, and the processor 21 is electrically connected with the second sensor to transmit the abnormal information to the remote terminal 203 when the second sensor detects that the motion state is abnormal. The second sensor may be an acceleration sensor or a velocity sensor or the like to monitor the state of motion of the portable infusion device 100.
The abnormal motion state comprises the following steps: the user falls down or is impacted, and the condition of transfusion can be influenced by the fast moving speed of the user.
