How does the pediatric bone puncture model simulate real puncture operation?

The pediatric bone puncture model simulates real pediatric bone marrow puncture operations through highly simulated design and precise mechanisms. Here is a detailed explanation of how the pediatric bone puncture model simulates real puncture operations:

Material and structure: Pediatric bone puncture models usually use PU foam to simulate leg muscles and polymer materials to simulate skin, which makes the model look and feel very similar to real human tissue. The skin and tibial bone marrow puncture parts of the model can be replaced to suit different teaching and training needs.

Selection of puncture point: The suitable puncture location is indicated on the model, such as the medial side before 1cm below the level of the tibial tuberositas, etc. These positions are set according to the real human anatomy. Users can choose the appropriate piercing point according to their needs.

Needle sensation and frustration: When pierced on the model with a dedicated bone marrow puncture needle, the model provides a true needle sensation. Once the needle contacts the "bone", the user will feel a certain resistance, and when the needle enters the "bone marrow cavity", this resistance will suddenly disappear, the so-called "frustration". The experience is very similar to that experienced during a real piercing operation.

Bone marrow fluid simulation: After the puncture is successful, the user can draw simulated bone marrow fluid through the syringe on the model. This simulated bone marrow fluid is similar in appearance and texture to real bone marrow fluid, further enhancing the authenticity of the training.

Complication simulation: While most models focus primarily on normal puncture procedures, some advanced models can also simulate possible complications or unexpected conditions during puncture, such as bleeding, infection, etc. This helps users understand and respond to these potential risks.

Feedback and evaluation: Many pediatric bone puncture models are equipped with feedback and evaluation systems. During training, the model can provide real-time feedback on the position, Angle and depth of the piercing, helping users correct mistakes and improve their skills. After the training, the model can also give the overall score and evaluation report for users' reference and learning.

Overall, the pediatric bone puncture model simulates real-world pediatric bone marrow puncture operations through its unique material, structural, functional characteristics, and feedback and evaluation systems. This kind of simulation training not only improves the authenticity and effectiveness of training, but also reduces the risk in real operation.
