Background

Intravenous infusion is the most common treatment means in clinical medical work, and is a method for infusing a large amount of sterile liquid, electrolyte and medicaments into a patient from the vein by utilizing the principles of atmospheric pressure and hydrostatic pressure so as to achieve the aim of relieving or treating the disease of the patient. According to the research at home and abroad, more than 90 percent of hospitalized patients need to receive the intravenous infusion treatment at present. One of the more common conditions in infusion is: when the liquid is not replaced in time, the air is easily entered into the lower end of the Murphy's dropper, and when a patient or an accompanying person notices that the liquid medicine in the infusion hose descends rapidly, panic is easily caused. When the nursing staff is busy, the nursing staff cannot timely arrive at the bedside of the patient to carry out the next operation. However, because the venous pressure is significantly greater than the static pressure of the fluid in the infusion tube below the regulator or because there is convection at the interface between the two fluids, a fluid pressure differential is created which can cause the blood in the blood vessel to flow back into the infusion tube. At this time, blood return is easily caused for the venous indwelling needle, a patient or an accompanying person is easily stressed and frightened, dissatisfied emotion is easily generated for nursing work, the hospitalizing experience of the patient is influenced, and the integral satisfaction degree of a hospital is reduced; for deep vein catheterization, the infusion dripping speed stops, blood flows backwards, so that thrombus is easily caused, the body health of a patient is affected, the working strength of medical staff is increased, and doctor-patient disputes are easily caused.
