Background

At present, to the infusion management in hospital ward, the management and control is carried out through the mode of bed calling set and nurse station intercommunication to the majority, mainly relies on nurse or care giver's control. The manual management and control mode of a nurse is a main mode used by a current hospital in the process of carrying out infusion on a patient, and the infusion speed is manually adjusted by the nurse; if the transfusion is finished abnormally in the titration process, the nurse cannot find and take measures in time, and the conditions of blood coagulation, air flushing of blood vessels and the like can be caused. The medical opportunity is delayed if the risk is small, and medical accidents are caused if the risk is large. The infusion apparatus used clinically at present is single, and the structure is also comparatively simple, does not talk about intellectuality. The monitor of the existing medical infusion control system can only know the information of the infusion speed (drop/minute) of an infusion patient through a monitor in a doctor office or a handheld monitor in a hand of a nurse, and cannot realize the real-time control of the infusion speed (drop/minute) of the infusion patient, in this case, when the infusion speed (drop/minute) of the patient is too fast or too slow, the doctor and the nurse can only go to the patient to adjust the infusion speed (drop/minute) so as to achieve the speed (drop/minute) required by treatment, and therefore, the working intensity of medical staff is increased.

In the prior art, CN 101837154A adopts an infusion monitoring system based on ZigBee technology, which includes an infusion hanging bottle, other liquid volume sensors, a sensing signal preprocessing circuit, a management end located in a nurse station, and a client end located in a ward, but the system actually performs detection only on a single client end, and does not perform fusion improvement from the perspective of the system. How to improve the accuracy of infusion management and the like becomes a problem to be solved without changing the existing system, how to fully utilize the development of the existing network technology, intelligentize and highly-efficiently monitor the existing infusion management, and matching the system with the existing infusion becomes a focus of attention of medical information technology medical companies actually without changing the existing management mode and application habit.

The gravity sensor mainly obtains a gravity sensing AD value through the microgravity sensor, continuously samples 90 points in 1 second, filters out the maximum and minimum 10 numerical values of the AD value of the 90 points, then keeps 80 AD values, and obtains a final accurate gravity sensing value through a DFT algorithm, wherein the accuracy is 0.1 g. The liquid crystal display unit can display the weight of the current infusion bag, including net weight, gross weight, residual liquid amount, real-time dripping speed per minute (the dripping speed is obtained by wireless pairing of an infrared part), and various state displays (infusion, infusion completion and non-infusion).

The detection of the empty state and the full state of the infusion tube mainly judges the corresponding state through the medium change of the infusion tube. The infrared dropping speed detection unit mainly sends and receives the liquid drops through the infrared geminate transistors, when the liquid drops drop, because the liquid drops are spherical, when the liquid drops pass through the infrared geminate transistors, infrared rays contact spherical liquid to be refracted, the real-time dropping speed is obtained through the refraction principle and filtering calculation, and then the real dropping number in one minute is obtained through a time lapse algorithm.

The residual liquid amount monitoring principle is that a weighing sensor is used for acquiring the real-time weight of the infusion bag, and the amount of liquid which is infused is calculated according to the difference value of the initial weight and the real-time weight.

The dripping speed measurement principle is that the MCU controls the infrared transmitting tube to be continuously conducted and transmit infrared rays, and the infrared receiving tube can receive signals of the infrared transmitting tube under normal conditions. When liquid medicine drips, the water drops can block infrared receiving, the liquid drops are judged to fall at the moment, and the MCU can calculate the dripping speed of the dripping according to the shielding time between the two drops.

The detection that the infusion was accomplished, the infusion is accomplished and is detected and adopt the electric capacity induction principle, places the response electric capacity piece in the upper end of transfer line, is a capacitance value when being the air traffic control, and the capacitance value will change when having liquid medicine, judges through the difference of capacitance value whether the infusion is accomplished.

Before the infusion monitoring terminal is not used, the whole infusion monitoring terminal is in a standby mode, the infusion monitoring terminal can be started only by pressing a starting button, and the infusion monitoring terminal can be automatically shut down when not used. When the start button is pressed, the display screen is lightened, and the working lamp normally flickers. After the infusion monitoring terminal (namely the infusion monitor) works normally, the infusion bag is firstly hung on the hook of the weighing part. Then the infusion dropping funnel is clamped into an infusion tank at the infrared part of the infusion monitor, an infusion line above the dropping funnel is clamped into a liquid medicine capacitance induction hole, the infusion line can be suspended in the air after the infusion line is clamped, and at the moment, the infusion monitor can automatically detect the dropping speed.
