The Human Respiratory System Model (Blister/Relief Design) by IBEX SCIENCES is a 3D anatomical teaching tool designed for biology classrooms, medical simulation labs, and clinical patient settings.
Using a graphic blister/relief section format mounted to a durable baseboard, this model provides a front-facing, comprehensive view of the entire airway system. It simplifies learning by allowing students and patients to trace the movement of air from the upper nasal passages down into the deepest structures of the lungs. [1]
Key Visual and Structural Structures
The relief format cuts open specific sections of the airway to reveal internal structures, tissue linings, and vascular systems:
-
- The Upper Respiratory Tract: Features an open-coronal view of the nasal cavity, oral cavity, pharynx, and larynx (voice box), detailing structural features like the epiglottis and vocal cords. [1]
- The Trachea & Bronchial Tree: Highlights the rigid, C-shaped cartilaginous rings of the windpipe (trachea). It splits clearly at the carina into the left and right primary bronchi. [1, 2]
- The Lungs (Internal & External Views): Typically, one lung is depicted with its smooth outer lobes intact, while the opposing lung is cut open to showcase the intricate, tree-like branching of the bronchioles and pulmonary blood vessels. [1]
- Microscopic Inset (Alveoli): Many IBEX relief models include an enlarged, microscopic inset diagram directly on the board to illustrate the structure of an alveolus (air sac) and capillary network where gas exchange takes place.
- The Muscular Diaphragm: Clearly displays the dome-shaped muscle at the base of the chest cavity, emphasizing its critical mechanical role in inhalation and exhalation.
Manufacturing and Quality Features
-
- Resilient PVC Plastic: Constructed from high-grade, non-toxic polyvinyl chloride (PVC). It resists warping or cracking over years of active classroom hand-outs. [1, 2]
- High-Contrast Hand Painting: Painted with vivid, durable pigments. Oxygen-rich pulmonary veins (red) and oxygen-depleted pulmonary arteries (blue) are clearly color-coded to prevent conceptual confusion. [1, 2]
- Numbered Key Indexing: Key anatomical structures are physically numbered on the relief plate. This coordinates with an accompanying reference guide, making it a turnkey tool for practical lab exams and self-study.
Primary Educational & Clinical Uses
-
- Anatomy & Physiology Labs: Ideal for secondary and university science courses covering gas exchange mechanisms, cellular respiration, and the mechanics of breathing.
- Clinical & Pulmonology Consultation: Allows physicians and respiratory therapists to visually explain pathologies such as asthma, COPD, bronchitis, and pneumonia to patients.
