Background

Intravenous bolus medication is the most common technique of care procedures in emergency, ICU, anesthesia, pediatric, etc. care patients. The medicine is injected into the vein instantly and accurately, so that the critical conditions of arrhythmia, epileptic persistence, asthma attack and the like of the patient can be corrected early, and finally the patient is put in danger. Therefore, the first-aid medicine is injected into the vein in time, accurately, uniformly, slowly and in small dose (1-10 ml), which is the key of first aid and also is a treatment mode for enabling a patient to obtain effective medicine at the first time.

However, in the treatment process, the speed of a lot of drugs injected by intravenous injection is not suitable to be too fast, the speed of the drugs needs to be controlled within a certain range, and if the speed is too fast, adverse reactions such as allergy and the like can be caused, and serious patients can die. For example, diazepam is 10mg (2ml), and intravenous injection is not suitable for too fast speed, 2-5 mg per minute; aminophylline, lidocaine, sedative hypnotics and the like, when intravenous injection is carried out, the speed is not suitable to be too fast, the medicine is controlled within a certain range, and if the speed is too fast, the death of a patient can be caused. Therefore, when small-dose medicines need to be injected into veins immediately, nurses need to strictly follow medical advice to inject the medicines slowly, and control the speed and the slow degree of the small-dose medicines by themselves, the requirements of being more than or equal to 5min should be met, but the clinical operation is difficult, if 2.5ml of the medicines need to be injected into the veins for more than 5min, the nurses need to select a 5ml syringe to extract the liquid medicines, the times for hanging the watch are required to be watched at any time during injection, and the speed for injecting the 2.5ml of the liquid medicines is controlled at the same time, so that the constant speed and the time for more than 5min are required to be completed.
