[0018] Place the prepared infusion bag between the frame plate 1 and the inflatable bag 3, connect the infusion tube 17, insert the infusion tube into the infusion tube fixing slot 12, place the infusion dropper 19 into the groove of the optical monitoring probe 6, and insert the lower end of the infusion tube into the slot of the flow regulator 16. Then fix the fixing belt 7 or the hook 9 on the body of the infusion subject or on a stretcher or bedside where the infusion device can be hung. The device and the fixing belt are connected by a universal shaft 10. Under the action of gravity, the device will remain perpendicular to the ground. Next, the operator starts the device and adjusts it to the initial mode. At this time, the control panel 2 in the device sends a signal command to the inflation pump 4, causing it to slowly inflate and squeeze the infusion bag 15. The liquid in the infusion bag is slowly injected into the infusion tube 17 to expel the air therein. When the needle 18 continuously drips liquid and there is no air in the infusion tube 17, the operator presses the pause button on the control panel 2. When the pause button is pressed, the control panel 2 sends a signal command to the air pump 4 and the flow regulator 16. At this time, the air pump 4 stops inflating the air bag 3 to stop it from expanding. At the same time, the flow regulator 16 is closed to the maximum state. The liquid in the infusion tube 17 is no longer circulating, and the needle 18 stops dripping liquid. The operator inserts the needle 18 into the vein of the infusion subject. After the blood backflow phenomenon is found, the needle 18 is fixed with medical tape. Next, the operator sets the drip rate of the intravenous infusion through the control panel 2. After the drip rate is set, it will be displayed on the display screen 8 in Arabic numerals. Next, the control panel 2 sends a signal command to control the flow regulator 1 6 is opened, at this time the liquid in the infusion set begins to drip into the body of the infusion subject, the optical monitoring probe 6 in the device will monitor the dripping speed of the liquid in the infusion set dropper 19 and feed it back to the control panel 2, the control circuit 2 in the control panel will calculate and adjust the inflation amount of the inflatable bag 3 by the air pump 4 according to the set dripping speed, control its expansion degree, adjust the pressure on the infusion bag 15, and at the same time adjust the opening and closing degree of the flow regulator 16 to adjust the flow rate. When the actual dripping rate monitored by the optical monitoring probe 6 is consistent with the set dripping rate, the air pump 4 and the flow regulator 16 will temporarily remain in this coordinated state for a period of time. As the liquid in the infusion bag 15 continues to flow out of the infusion bag, the volume of the infusion bag becomes smaller, the pressure of the air bag 3 on the infusion bag 15 is insufficient, and the liquid in the infusion set dropper 19 is insufficient. When the dripping rate of the liquid is lower than the dripping rate set by the device, the control circuit in the control panel 2 will recalculate and issue a command to the air pump 4 to add pressure to the air bag 3. When the actual dripping rate matches the set dripping rate for the second time, the previous process will be repeated until all the liquid in the infusion bag 15 is dripped out. When the optical monitoring probe 6 detects that there is no more liquid dripping in the infusion dropper 19, it means that the infusion bag 15 is already in an empty dripping state. The optical monitoring probe 6 will feed this signal back to the control panel 2. After receiving the signal, the control panel 2 will issue a signal command to stop the air pump 4 from inflating the air bag 3. At the same time, the flow regulator 16 is turned off to reach the maximum closed state. At this time, the infusion device stops infusing the infusion object, but the existing pressure is maintained in the infusion tube of the infusion device to prevent blood backflow.At this time, the voice speaker 13 will sound a prompt to indicate that the infusion is over, and the operator will remove the needle to complete the entire infusion process. This device is designed with a heating function. If there is a special need to heat the infusion, the heater 11 can be controlled through the control panel 2 to heat the infusion bag. This device changes the original principle of gravity infusion relying on the height difference to drip in, solving the problem of insufficient height to be able to infuse normally. At the same time, it solves the problem of gravity infusion being inconvenient to implement when rescuing and transporting the wounded, and improves the problem of the restricted movement of the infused object in normal environments and requiring the cooperation of nursing staff to move. This device is suitable for the use of most ordinary and universal infusion bags, and there is no need to consider model matching issues. This device has no contact with the infusion liquid, eliminating the problem of contamination of the infusion liquid. The device is small in size and light in weight, easy to carry and can be used repeatedly. The above is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, expansions, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
