Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of infusion auxiliary medical equipment, and in particular to an infusion dripping rate intelligent adjustment detection alarm system and device. Background Art
[0002] As a common and important treatment method in clinical medicine, intravenous infusion therapy is widely used in the treatment of inpatients and outpatients. This method directly injects drugs into the patient's venous system to achieve rapid and effective drug administration, which plays a vital role in the treatment of diseases and the recovery of patients. However, in actual operation, intravenous infusion therapy faces many challenges, especially in the regulation and control of the infusion drip rate.
[0003] In actual operation, due to the influence of various factors, it is often difficult for the infusion rate adjusted by the nurse to remain constant.
[0004] 1. The height of the distance from the infusion bottle to the puncture point is an important factor affecting the infusion speed. In an ideal infusion environment, patients usually sit on an infusion chair at a relatively constant height to ensure the stability of the infusion speed. However, for patients such as children who find it difficult to sit still, they often like to move around, resulting in frequent changes in the height of the infusion bottle, which in turn affects the stability of the infusion speed.
[0005] 2. The patient's body position or the placement of the limb at the puncture site also has a significant impact on the infusion rate. Especially for patients using indwelling needles, the indwelling needle hose is placed in the patient's blood vessels. Certain postures may cause the hose to be partially folded inside or outside the body, thereby hindering the smooth infusion of the drug and affecting the infusion rate.
[0006] 3. Some patients or children may adjust the infusion switch by themselves, further aggravating the instability of the infusion speed.
[0007] 4. Although the micro-injection pump of the existing technology can accurately control the infusion speed, it is not suitable for patients who need to receive ordinary drug infusion. On the one hand, the micro-injection pump is large in size, inconvenient to use, and expensive, which increases the economic burden on hospitals and patients. On the other hand, the amount of liquid in outpatient infusion patients is usually large. If a micro-injection pump is used for infusion, it will greatly increase the workload of nurses and also increase the investment cost of the hospital.
[0008] In summary, intravenous infusion therapy faces many challenges in regulating and controlling the infusion drip rate. How to improve the stability of the infusion rate, reduce the workload of medical staff, and reduce the economic burden of hospitals and patients while ensuring the safety and effectiveness of infusion therapy is an important issue that needs to be solved in the current field of intravenous infusion therapy.
