The unit of measurement for a 1 ml syringe is milliliters, and the clinical model is usually used in the middle model with a diameter of 0.45 mm and 0.55 mm (brown, orange).
Insulin injections are divided into 40 units/ml and 100 units/ml. U-40 syringes can only extract 40 units of insulin per ml. U-100 syringes can only extract 100 units of insulin per ml. Both syringes are 1ml in capacity, but the unit scale is different. The U-40 syringe has 40 small cells, each small cell is equivalent to 40 units/ml of insulin type, and the unit scale is as small as 0.025ml; U- The 100 syringe has 50 cells, each of which is equivalent to two units of insulin in a 100 unit/ml dosage form, with a unit scale as small as 0.02 ml. It can be seen that the insulin of different dosage forms should be respectively applied to the corresponding syringe, otherwise the injection dose will be wrong. U-40 and U-100 syringes should not be used indiscriminately and can only be used with their own pharmaceutical dosage forms.
Strictly speaking, it is not recommended for aspirating and aspirating injections of insulin. Because the use of a 1 ml syringe to pump insulin in any dosage form requires a conversion meter, such as 40 units/ml of insulin 0.1 ml equivalent to 4 units, 100 units/ml dosage form of insulin 0.1 ml equivalent to 10 units. Insulin belongs to Class A high-risk drugs (the highest level of high-risk drugs) in high-risk drugs published by the American Medical Safety Association in 2009. Once the medication is wrong, it will cause death to the patient. Therefore, it is not recommended to use a normal 1 ml syringe to pump insulin by conversion method, which will bring many safety hazards to the clinic.
Advantages and disadvantages of 1 ml syringe and U-40, U-100 syringe in insulin use
The model of the 1 ml syringe of the equipment and equipment department is only 0.45*16mm. The needle is connected to the syringe through the thicker syringe nipple, which results in a larger dead space of the syringe and a larger error when pumping a small amount of liquid medicine. U-40, U-100 syringe is a fixed needle specially designed for pumping insulin, needle and syringe barrel, and the syringe nipple is thin, so the dead space is small or no dead space, safe to use, avoid waste .
The needles of the U-40 and U-100 syringes are thinner and shorter in diameter and length, so the damage to the injected skin is small and the pain is lighter. U-40, U-100 syringes are not required to be converted, and the readings are accurate.
