卡塔尔采购需求：教学设备，医学模型，解剖模型，医疗器械，骨骼模型，心肺复苏模型

I am interested in obtaining quotes for a variety of anatomical models and scientific representations. Specifically, I am looking for information on a skeletal system model, various human body models, and models of specific organs, including the brain, heart, and respiratory system. Additionally, I'd like to see quotes for representations of different animals and systems, such as fish and rabbit skeletons, as well as models showcasing the solar system and auditory mechanisms. Please provide pricing details for each available product in your range that corresponds to these categories. It would be great if you could also include any relevant information concerning bulk purchasing options and lead times for availability. Thank you for your assistance!
