[0002] Intravenous infusion is the most commonly used treatment measure in clinical practice. Liquids such as drugs, nutrients or electrolytes are directly infused into the patient's body through intravenous drip to achieve the effect of treating diseases. The dosage is more than 100ml at a time. Infusion sets are usually used for intravenous drips. Drugs are continuously and stably infused into the body to quickly and effectively treat diseases or supplement nutrition. It is a common treatment and nursing method in modern medicine and is widely used in hospitals, clinics and emergency situations.
[0003] However, the infusion process often takes several hours or even longer. Clinically, it usually relies on the care of family members to monitor the speed and amount of infusion, or nurses rely on clinical experience to estimate the time to replace the infusion bottle. Medical staff often respond slowly to emergency calls, resulting in safety hazards such as delayed replacement of infusion bottles, venous blood return, and venous access blockage. In addition, most family members lack knowledge of the pharmacology of drugs and do not know how to correctly supervise the drip speed of fluid replacement, resulting in the drip speed of fluid replacement being too fast or too slow, so that the drug cannot achieve an effective therapeutic effect, and in severe cases, even endangering the patient's life; in addition, when the patient's family members directly call to replace the infusion bottle, the nursing station has insufficient nursing human resources, and the patient's long waiting time is likely to cause dissatisfaction; patients without family members need to monitor the drip speed and amount of fluid replacement by themselves, which increases the burden on the patients and greatly affects the rest quality of the patients and accompanying personnel at night, affecting the patient's recovery; the nurse of this device can timely and effectively monitor the drip speed and amount of fluid replacement of the patient according to the comprehensive conditions such as the pharmacological properties of the drug, the patient's cardiopulmonary function, and the condition of the disease, and provide the patient with a fluid replacement speed and total amount suitable for the condition and drug properties, and can remind nursing staff to arrange work reasonably, replace the infusion bottle for the patient in a timely and effective manner, ensure the safety of the patient's infusion treatment, improve the work efficiency of nurses, and improve the job satisfaction of nurses.
