What does suit hypodermic injection drug have

Vaccine is subcutaneous injection more commonly, stimulant big, action fast drug muscle injection; Both belong to internal injection, the drug will not be lost through the first effect, so the difference between drug absorption and side effects is very small, but the absorption rate is different, the intramuscular injection will soon take effect.

Subcutaneous injection (H) Subcutaneous injection is the injection of a small amount of liquid medicine into the subcutaneous tissue, mostly used for therapeutic administration and vaccination.

1. Location: Use the depression of the deltoid muscle of the upper arm.

2. Operation method: Absorb the liquid and disinfect the injection site with iodophor first. Tighten the injection site with the left hand, hold the syringe (2ml syringe) with the right hand, make the incline of the needle upward, make an Angle of 30° ~ 40° with the skin, quickly Pierce the needle to about 2/3 of the needle, relax the skin, fix the needle, and inject all the liquid when there is no blood return from reverse pumping. After the injection, gently press the needle with a cotton ball and pull out the needle quickly.

Intramuscular injection (IM) intramuscular injection is the injection of liquid medicine into the muscle. It is often used in those cases where the effect of liquid medicine is rapid, or where the stimulant is not suitable for subcutaneous injection, or where the effect is more rapid than subcutaneous injection.

1. Site: generally, the site with thicker muscles and far away from the great nerves and great vessels is selected. The gluteus maximus is the most commonly used, followed by the deltoid and lateral femoris muscle.

Use cross law to determine gluteus maximus muscle to inject place commonly, introduce a horizontal line from gluteus crack vertex namely, make a perpendicular line with the midpoint of iliac crest and spinal line again, go up outside 1/4 place is inject place namely.

2. Methods of operation: Patients are generally placed in lateral decubitus position, with the upper leg straight and the lower leg slightly bent. Seats are also available. Expose the injection site and disinfect the skin with iodophor. After absorbing the liquid medicine, tighten the skin with the left thumb and finger, hold the syringe (2ml or 5ml syringe) with the right hand, and quickly Pierce the needle vertically into 2/3 of the needle, fix the needle, and no blood can be drawn back, then the liquid medicine can be injected. After the injection, pull out the needle and gently press the eye of the needle with a cotton swab until no liquid oozes out.
