In the specific implementation process, in the process of infusion of a patient, the weight of the infusion bottle and the liquid medicine is continuously reduced, the current elastic force of the stretched elastic rope 5 caused by elastic deformation is larger than the current gravity of the infusion bottle, the liquid medicine and the placing frame 4, and the infusion bottle and the placing frame 4 are pulled upwards by the elastic rope 5. For the hydraulic resistance of the hydraulic rod 8, the weight loss of the whole infusion bottle and the placing frame 4 per second is calculated according to the median value of the range value of the standard infusion speed of the liquid medicine, the lifting height of the whole infusion bottle and the placing frame 4 per second is calculated according to the weight loss per second, the lifting speed of the whole infusion bottle and the placing frame 4 is calculated, the lifting speed of the transverse shaft 9 and the arched sheet 10 under the condition of the flow speed is equivalent, the momentum is calculated according to the lifting speed, the impulse of the hydraulic rod 8 to the lifting of the transverse shaft 9 and the arched sheet 10 is obtained, and the hydraulic resistance value which should be set in the hydraulic rod 8 is obtained. When the current infusion speed is normal, the momentum of the rack 4 which is pulled to rise is consistent with the momentum of the hydraulic pressure resistance of the hydraulic rod 8, and the distance between the arched piece 10 and the transverse plate 7 is at a fixed value, so that the infusion speed can keep a fixed value when an infusion tube which passes through the connecting shaft 6, the transverse plate 7 and the arched piece 10 is in a normal state; when the current infusion speed is higher than the middle value of the standard infusion speed, the loss speed of the liquid medicine in the infusion bottle is accelerated, so that the integral gravity loss of the infusion bottle and the placing frame 4 is accelerated, the integral lifting speed of the infusion bottle and the placing frame 4 is accelerated by the elastic rope, namely the lifting speed of the transverse plate 7 is accelerated, the lifting momentum is increased, the momentum of the hydraulic pressure of the hydraulic rod 8 is temporarily kept at a fixed value due to the inertia, so that the lifting momentum of the transverse plate 7 is larger than the momentum of the arched plate 10, and the infusion tube passing through the space formed by the connecting shaft 6, the transverse plate 7 and the arched plate 10 is extruded and deformed by the transverse plate 7 and the arched plate 10 due to the fact that the transverse plate 7 is positioned below the arched plate 10, so that the infusion speed is temporarily slowed down, and the integral gravity loss of the infusion bottle and the placing frame 4 is slowed down, the infusion bottle and the whole rack 4 are pulled by the elastic rope to rise slowly, the momentum is reduced, the transverse plate 7 rises to reduce the momentum, the impulse of the hydraulic pressure resistance of the hydraulic rod 8 is kept unchanged due to inertia, the distance between the transverse plate 7 and the arched sheet 10 is increased, the deformation of the infusion tube is gradually recovered, and the infusion speed is gradually increased until the infusion speed is consistent with the standard infusion speed; it should be noted that the infusion tube adopted by the invention is an elastic infusion tube, for the infusion tube passing through the connecting shaft 6, the transverse plate 7 and the arched piece 10, the part of the infusion tube is fixed on the transverse plate 7 and the arched piece 10, and the part of the infusion tube in the state of the standard infusion speed is in a slightly compressed state, therefore, when the current infusion speed is less than the middle value of the standard infusion speed, the loss speed of the liquid medicine in the infusion bottle is reduced, the overall gravity loss of the infusion bottle and the placing frame 4 is reduced, the overall lifting speed of the infusion bottle and the placing frame 4 is reduced by the traction of the elastic rope, namely, the lifting speed of the transverse plate 7 is reduced, the momentum of the hydraulic pressure in the hydraulic rod 8 is kept constant, the momentum of the lifting of the transverse plate 7 is less than the momentum of the hydraulic rod 8, because the transverse plate 7, thereby make the transfer line that passes in the space that comprises connecting axle 6, diaphragm 7, arch piece 10 receive the drawing of diaphragm 7 and arch piece 10 and take place deformation, and then lead to the infusion speed to increase temporarily, thereby make the loss speed of liquid medicine in the infusion bottle accelerate, the whole loss of gravity of infusion bottle and rack 4 accelerates, the speed that the whole of infusion bottle and rack 4 received the stretch cord traction to rise accelerates, diaphragm 7 rises to the speed and accelerates, because the momentum of liquid pressure resistance in hydraulic stem 8 keeps unchangeable, and then make the distance between diaphragm 7 and the arch piece 10 diminish, the deformation that the transfer line took place recovers gradually, and then lead to the infusion speed to slow down gradually, reach the unanimity until infusion speed and standard infusion speed.
Aiming at patients with different ages and different illness states, medical staff give targeted standard infusion speed ranges and input the infusion speed ranges into the terminal device 11, and the processing device 13 obtains the standard infusion speed ranges in the terminal device 11 and controls the hydraulic pressure regulating and controlling device 12 to regulate the hydraulic resistance in the hydraulic rod 8 according to the method.
When the processing device judges that the current infusion speed is greater than the maximum value of the standard infusion speed range or less than the minimum value of the standard infusion speed range, the processing device judges that the infusion condition at the moment is in an emergency, the processing device sends a control instruction to the warning device, the warning device sends a voice warning, and meanwhile, the processing device sends a signal of a user request to the medical care system to call medical care personnel for processing.
