High Quality Portable Rate Adjustable Syringe Infusion Pump Electric Iv Infusion Pump

Evaluation of clinical application value of special infusion pump pipeline

With the continuous improvement of the level of rescuing critically ill patients, higher requirements have been put forward for not only the type and total amount of intravenous infusion, but also the uniformity and accuracy of infusion speed.
Infusion pump is a device that can accurately control the infusion speed and ensure that drugs can be uniformly and safely injected into the patient’s body. Infusion pump uses peristalsis, rotary extrusion and double piston extrusion to drive the accurate injection of drugs into the vein, it can preset the infusion speed, set the infusion total amount and infusion time. It can improve the work efficiency and nursing level of nurses, and reduce the work intensity.
In order to ensure the accuracy and safety of infusion, most infusion pump manufacturers recommend the use of the original manufacturer’s special infusion set. At present, the conventional disposable infusion set in clinical use (that is, non-special infusion set) is clearly marked on its packaging that it is limited to the use of gravity Af cost, consumables and charging process, etc., and the hospital still generally uses ordinary disposable infusion set for accurate infusion. In such a realistic situation, how high is the clinical application value of the special infusion set? Does the non-dedicated infusion set affect the accuracy of the infusion pump to an acceptable level?
Through the processing of experimental data, we found that infusion sets of different manufacturers have significant influence on infusion accuracy without considering the error or certain error of infusion and testing equipment. The original infusion set has obvious advantages in both the overall error range and the error distribution range. The difference of the error must be related to the material, thickness, diameter and production process of the infusion set.
If the infusion error caused by the ordinary infusion set is within the allowable range, the hospital can continue to use it from the aspects of cost control and convenience. However, through the experiment, we found that the speed error distribution of non-original disposable infusion set is very large, and individual samples even have 70% error, which cannot but attract the attention of clinical use departments. Such as sodium nitroprusside commonly used in clinical practice, as a fast-acting and short-acting vasodilator, the common dose is 3ug/kg per minute, if the infusion speed is too fast it is easy to cause hypotension and even shock. For example, pediatrics has a very strict limit on the amount of fluid supplementation for newborns, and the amount of fluid supplementation should not exceed 20 ml/kg every 30 minutes, otherwise it is easy to cause pulmonary edema and heart failure. For the use of these special patients, we recommend that from the perspective of clinical safety, a special infusion set should be used.
We found in the experiment that the relationship between the use error of the infusion pump and the use temperature is very large, and the lower the temperature, the greater the error. In order to ensure the accuracy of the experiment, we strictly controlled the ambient temperature of the laboratory at 25°C, and placed all the experimental equipment in the laboratory for more than 1 h before the experiment. In order to ensure the accuracy of clinical use, we recommend that the working temperature of the infusion pump and infusion set and the temperature of the infusion drug should be controlled above 20°C during the clinical infusion of patients
