Abstract

An intelligent infusion pump includes a housing; a control circuit board; an input and display device; and a support base mounted on the housing to support a dropping bottle. The housing has an air cleaning device that communicates with an air inlet of an air pump of a motor pump assembly. 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.

Claims

1. A method to transfuse utilizing an intelligent infusion pump, wherein the intelligent infusion pump comprises:

a housing;

a control circuit board mounted in a lower part of an interior of the housing;

an input and display device 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;

wherein, a back of the housing is provided with an air cleaning device, 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;

an air outlet of the air pump of the motor pump assembly is connected with a seal joint mounted on the front surface of the housing via a first air pipe with an air check valve, and an air pressure sensor is mounted on a second 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 and a power supply device, and an infrared detection head is mounted on the front surface of the housing and placed under the support base; and

the control circuit board is electrically connected with the input and display device, the motor pump assembly, the air pressure sensor, the infusion flow control mechanism, the infrared detection head, and the power supply device;

wherein, a transparent window is mounted on a back of the support base, a scanner is mounted in the housing and electrically connected to the control circuit board, and a scanning head of the scanner is aligned with the transparent window; and

wherein, the support base is configured to support the dropping bottle in such a way that the dropping bottle supported by the support base is used for infusion and a bar code on the dropping bottle supported by the support base is simultaneously aligned with the scanning head through the transparent window to be scanned through the transparent window by the scanning head;

wherein, the infusion flow control mechanism includes a micro motor electrically connected with the control circuit board, a reciprocating movement mechanism and a limit switch connected with the micro motor, and a back plate placed in a movement direction of the reciprocating movement mechanism;

the micro motor drives the reciprocating movement mechanism to press an infusion tube onto the back plate or release the infusion tube;

an ultraviolet diode configured for sterilization is mounted inside the seal joint;

wherein the method comprises;

utilizing the power supply device to provide power to the intelligent infusion pump;

placing the dropping bottle on the support base;

fixing a infusion observation bottle on the support structure with the infrared detection head;

connecting the infusion tube to a liquid outlet of the infusion observation bottle and fixing the infusion tube between the back plate and the reciprocating movement mechanism of the infusion flow control mechanism;

connecting a third air pipe to the dropping bottle, and connecting a joint of the third air pipe to the seal joint;

using the input and display device to determine infusion rate and infusion quantity; and

infusion process which comprises;

sucking air via the air cleaning device;

filtering and sterilizing the air, and then inputting the air to the air pump via a fourth air pipe;

compressing the air and outputting the compressed air to the seal joint via the third air pipe; and

injecting the compressed air into the dropping bottle via the third air pipe;

when passing through the seal joint, re-sterilizing the compressed air by ultraviolet sent from the ultraviolet diode mounted in the seal joint;

wherein, under the action of the compressed air, liquid medicine in the dropping bottle enters the infusion observation bottle via the infusion tube, and is infused to a patient via the infusion tube;

the infrared detection head is used to detect liquid drops in the infusion observation bottle and send a detection signal to the control circuit board;

the control circuit board sends instruction to the micro motor of the infusion flow control mechanism, and thus the micro motor drives the reciprocating movement mechanism to press the infusion tube onto the back plate or release the infusion tube.
