Bone marrow puncture training model

The bone marrow puncture training model is a specialized teaching aid often used in medical education and clinical training, mainly for simulating the entire process of bone marrow puncture operation. This model is usually designed based on the structure of human bones and soft tissues. Common puncture sites such as the posterior superior iliac spine, anterior superior iliac spine or sternum position are clearly marked, and it is equipped with replaceable "bone marrow cavity" materials, which can realistically reproduce the puncture feel.

In teaching applications, teachers can use models to demonstrate the correct posture, positioning methods and operation steps for puncture. During the training process, students can learn the aseptic operation procedures, the control of the insertion Angle and depth of the puncture needle, and determine whether it has entered the bone marrow cavity through tactile feedback. This simulation experience can effectively reduce the tension in clinical practice and lay a foundation for independent operation on patients in the future.

During the training, trainees need to repeatedly practice the processes of puncture, aspiration and specimen collection to become familiar with the entire operation procedure. Some high-end models are also equipped with replaceable bone marrow fluid simulation devices, enabling trainees to complete sampling training in an environment close to reality.

After the operation is completed, the consumables should be replaced in time and the model cleaned to avoid damaging the structure. Through standardized use, the bone marrow puncture training model not only enhances the practical skills of medical students but also provides a reliable platform for clinical teaching and assessment.
