Intramuscular Injection Model

This model with realistic skin is perfect for teaching proper injection techniques and how to avoid nerves and veins. The see-through right side of the model shows internal structure including bones, muscles, nerves, and veins. The gluteus medius, nerves, veins, ilium crista, and greater trochanter can be palpated to confirm the correct injection points. Fluid injected in the proper place is discharged through a drain tube into drain bag. A green light indicates correct injection technique and positioning – a buzzer and flashing red light warn students if they have gone too deep or if needle position is incorrect.

Intramuscular Injection Model

Intramuscular injection, often abbreviated IM, is the injection of a substance into a muscle. In medicine, it is one of several methods for parenteral administration of medications. Intramuscular injection may be preferred because muscles have larger and more numerous blood vessels than subcutaneous tissue, leading to faster absorption than subcutaneous or intradermal injections.[1]:751 Medication administered via intramuscular injection is not subject to the first-pass metabolism effect which affects oral medications.

Uses

Intramuscular injection is commonly used for medication administration. Medication administered in the muscle is generally quickly absorbed in the bloodstream, and avoids the first pass metabolism which occurs with oral administration. The medication may not be considered 100% bioavailable as it must still be absorbed from the muscle, which occurs over time. An intramuscular injection is less invasive than an intravenous injection and also generally takes less time, as the site of injection (a muscle versus a vein) is much larger. Medications administered in the muscle may also be administered as depot injections, which provide slow, continuous release of medicine over a longer period of time. Certain substances, including ketamine, may be injected intramuscularly for recreational purposes. Disadvantages of intramuscular administration include skill and technique required, pain from injection, anxiety or fear (especially in children), and difficulty in self-administration which limits its use in outpatient medicine.
