The infusion management system that application figure 5 shows carries out data transmission through infusion controller's communication module and host computer for the infusion situation of patient end can real-time concentrated demonstration to the host computer, so that medical personnel in time know different infusion situations of different patients fast, make corresponding processing, consequently, has reduced medical personnel's work load, has improved medical personnel's managerial efficiency to patient's infusion.
Furthermore, an embodiment of the present invention further provides an infusion management control method, which may include:
the main control module receives a speed adjusting signal generated by the fact that the infusion setting rod touches the collision detection block, generates control signals of the two motors and sends the control signals to the two motors, so that the two motors drive the infusion extrusion block to move up and down, extrude or loosen the infusion tube, adjust the liquid dropping speed, calculate the current liquid dropping speed and the remaining infusion duration, and send the current liquid dropping speed and the remaining infusion duration to the upper computer through the communication module to display.
Use this embodiment, drive transfer line extrusion piece to the transfer line extrusion through host system control motor, reach the purpose of adjusting dropping liquid speed to it is long when calculating current dropping liquid speed and infusion surplus, send the host computer demonstration to make medical personnel can in time know the current infusion state of patient, because the current patient infusion state of demonstration that the host computer is concentrated, also reduced medical personnel's work load, improved medical personnel's the managerial efficiency of patient's infusion.
In one case, the speed adjustment signal generated when the infusion setting lever touches the collision detection block may be an adjustment signal for increasing the speed or an adjustment signal for decreasing the speed. Every time the infusion setting rod touches the collision detection block, the collision detection block generates a speed regulation signal and transmits the speed regulation signal to the main control module, the main control module receives the speed regulation signal, the control signal generated by the two motors controls the two motors to rotate for a preset revolution number, the infusion extrusion block is driven to move downwards or upwards for a corresponding distance, the infusion tube is extruded or loosened, the cross section area of the infusion tube is correspondingly changed, namely the inner diameter of the infusion tube is correspondingly changed, and therefore the dropping speed is reduced or increased by 1 gtt/min.
For example, the infusion line may be of three types, 10gtt/ml, 15gtt/ml and 20gtt/ml, if the preset infusion line has a dropping coefficient of 20 (20 drops per ml), an inner diameter of 3mm, and a rated input volume per hour (i.e., a volume flow per unit time) of 250ml/h, i.e., 250 × 1000mm3The total amount of the liquid medicine to be infused is 500ml, and when 2h of infusion is expected to be finished, the infusion tube is not extruded, the number of drops per minute is as follows:
Figure BDA0001865178850000101
at this time, the rated flow rate of the infusion tube is:
Figure BDA0001865178850000102
drive the extrusion piece extrusion transfer line of infusion when the motor for the current internal diameter of transfer line becomes 2.8mm, and the flow of transfer line diminishes, and the rated flow rate does not change, so, this transfer line input volume per hour at present is:
Figure BDA0001865178850000111
or, at present, every smallTime input quantity is rated flow speed (mm/h) multiplied by current cross section area (mm) of infusion tube2)
＝8846mm/h×3.14×2.82mm2≈217.77ml/h；
At this time, the number of drops per minute of the infusion tube is:
Figure BDA0001865178850000112
as an implementation manner, another infusion management control method is further provided in the embodiments of the present invention, and in this implementation manner, the infusion management controller may further include a sheet metal function button and a display screen.
