The infusion pump is usually a mechanical or electronic control device that acts on the infusion catheter to control the rate of infusion. Commonly used in the need for strict control of the volume of infusion and drug dosage, such as in the application of antihypertensive drugs, anti-arrhythmic drugs, infants and children intravenous infusion or intravenous anesthesia.
The infusion pump can realize the following features:
1. It can accurately measure and control the speed of infusion, determine and control the volume of infusion, and report the abnormal situation of air bubbles, empty liquid, leakage and obstruction of infusion tube, and automatically cut off the infusion pathway.
2. Color OLED display for intelligent control of infusion. The product functions cover the basic functions of many popular products in the market, and have certain potential market value.
Technology application scope: Throughout the lack of movement nowadays, people are prone to get sick easily, hospitals can often be seen in a sea of people to play the IV, and now there are so many patients because of special diseases need to slowly according to a certain speed of the IV, if you rely on the nurses to keep an eye on the nurse, in this way, the nurse's workload is very large, and prone to produce human error.
So there is a need for an electrically powered medical device that can run and control the speed and time of the drip according to the nurse's wishes. Biopharmaceutical development and chemical industry, for example, some liquid drug ingredients to be configured in strict proportions, now the most common is the test tube dropper configuration, this way through the human eye to configure the drawbacks of a lot of, so there is a need for a precise measurement of the output of the liquid instrument.
Expanded Information:
Extending the life of an infusion pump. p>To prolong the service life of the infusion pump and to maintain the stability of its infusion, please follow the following precautions:
1. Prevent any solid particles from entering into the infusion pump body, because dust or any other impurities will wear out the plunger, sealing ring, cylinder, and check valves, so any solid particles in the mobile phase should be removed beforehand. The mobile phase should preferably be distilled in a glass vessel, while the usual method is filtration, which can be done with filters such as Millipore filter membranes. Sand filter rods should be attached to all pump inlets, and filters for infusion pumps should be changed frequently.
2, the mobile phase should not contain any corrosive substances, the mobile phase containing buffer should not be retained in the pump, especially if the pump is stopped overnight or longer. If the mobile phase containing buffer is left in the pump, due to evaporation or leakage, or even just due to the stillness of the solution, tiny crystals of salt may precipitate, and these crystals will damage the sealing ring and plunger, etc. as well as the solid particles mentioned above.
