This high-quality I.M. simulator represents a left upper arm with all important anatomical palpable landmarks such as acromion and humerus. The realistic anatomy allows for placing correct intramuscular injections in an exceptionally graphic way. The built-in fine electronics produce audio-visual feedback from the result. For example, correct or incorrect injection, bone contact, or wrong location. Additional trainings and control modes optionally provide an immediate or subsequent performance check under training conditions. The included lifelike silicone skin is extremely durable and can be quickly and easily exchanged when necessary. The intramuscular simulator is supplied with: 2 AA batteries, a detailed instruction manual, replacement skin, a 5-ml injection syringe and 21G/0.8 injection needle.
