Calculate how many milliliters are input per hour. Algorithm: the total number of drops per hour divided by the drop coefficient. (For infusion sets with a drip coefficient of 10/ml, 10 drop is 1ml, and for infusion sets with a drip coefficient of 15/ml, 15 drop is 1ml). ? For example, at the speed of 20 drops per minute, how many milliliters are dripped an hour with an infusion set with a drip coefficient of 10. ? Answer: 20x60/10 =1200/10 =120ml.
product usage
This product is used together with disposable intravenous infusion needle, mainly used for clinical gravity infusion.
principle of operation
Under the action of atmospheric pressure, the liquid in the bottle flows into the drip bucket along the thinner infusion hose. When the water column pressure of the drip bucket is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose.
operational approach
Before use, medical personnel should check the disinfection validity period of disposable infusion set and whether there is any abnormal situation such as air leakage in the package, take out the infusion set, and partially insert the bottle insertion needle into the infusion bottle (for infusion bag, unless it is an infusion set with an integrated air inlet pipe and bottle insertion needle, it is not necessary to open the air inlet device, that is, insert the air inlet needle or open the air inlet hole).
Hang the infusion bottle on the infusion pole, exhaust until the liquid medicine flows to the lower end of the infusion tube, close the regulator, then insert the intravenous needle into the sterilized vein, fix it, untie the tourniquet and adjust the flow rate.
Matters needing attention
1. belongs to one-time use and should meet the corresponding national hygiene quality standards.
2. Cross-use is prohibited
