An intelligent infusion pump for constant rate intravenous drug infusion to patients comprises: housing; a control circuit board (1) mounted in a lower part of the interior of the housing; an input and display device (2) mounted at a side of the housing; and a support base mounted on an upper portion of a front surface of the housing and configured to support a dropping bottle (3); wherein, a back of the housing is provided with an air cleaning device (4), an air inlet of the air cleaning device is arranged outwardly, and an air outlet of the air cleaning device is arranged inwardly and communicates with an air inlet of an air pump of a motor pump assembly (5); an air outlet of the air pump of the motor pump assembly is connected with a seal joint (8) mounted on the front surface of the housing via an air pipe with an air check valve (7), and an air pressure sensor (6) is mounted on an air pipe connected between the air check valve and the seal joint of the housing; the interior of the housing is further provided with an infusion flow control mechanism (9) and a power supply device, and an infrared detection head (10) is mounted on the front surface of the housing and placed under the support base; and the control circuit board (1) is electrically connected with the input and display device (2), the motor pump assembly (5), the air pressure sensor (6), the infusion flow control mechanism (9), the infrared detection head (10), and the power supply device. The air pump is used to provide pressure, so that common infusion tubes can meet the requirements and the cost can be reduced. By using the air cleaning device, the clean air does not cause contamination of the liquid medicine. The present invention is convenient to use, safe, and inexpensive. |
