An air outlet of the air pump of the motor pump assembly is connected with a seal joint via an air pipe with an air check valve. An air pressure sensor is mounted between the air check valve and the seal joint. The housing is further provided with an infusion flow control mechanism and a power supply device. An infrared detection head is placed under the support base.
