Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If textbooks and flash cards are used for patient care education, then the training can be conducted without risk to patients, but the hands-on practice benefits that students can attain are lost
Solution Approach 1:
The patent creates a simulated patient (manikin) that copies the physical and physiological characteristics of a real patient. The simulated patient includes realistic anatomical features, skin texture, and physiological responses that allow students to practice medical procedures on a copy rather than on real patients, thus eliminating patient risk while preserving hands-on practice benefits.
Solution Approach 2:
The simulated patient's physiological parameters (heart rate, blood pressure, respiratory rate, oxygen saturation) can be dynamically adjusted to simulate various clinical conditions. This allows students to practice on a controlled environment where parameters can be changed without affecting real patients, providing both safety and realistic practice opportunities.
2Ease of operation
If simulators are used for patient care training, then hands-on practice is enabled, but the realism and additional simulated features are insufficient
Solution Approach 1:
The simulated patient incorporates different materials and characteristics in different anatomical regions to enhance realism. For example, the skin has varying textures and colors to match different body parts, the chest wall has specific compliance characteristics, and the lung simulator has adjustable compliance to mimic real lung mechanics. This localized quality enhancement makes the simulation more realistic while maintaining hands-on practice capability.
Solution Approach 2:
The simulated patient uses composite materials to achieve realistic tactile and visual properties. The skin is made from materials that combine flexibility, texture, and color matching to resemble human skin. The chest wall uses composite structures that provide appropriate rigidity and compliance. These composite materials enhance the realism of the simulation while allowing for durable, reusable training equipment.
3Adaptability or versatility
If the available volume for the simulated lung to expand into is increased, then the lung compliance increases, but the realism of normal lung function is reduced
Solution Approach 1:
The lung compliance simulator uses a dynamic compression bag that can be inflated and deflated during the simulation. The bag's volume is not fixed but can be adjusted in real-time to change the available expansion space for the simulated lung. This dynamic adjustment allows the system to transition between different compliance states (normal, restrictive, obstructive) while maintaining accurate representation of real lung mechanics in each state.
Solution Approach 2:
The system changes the physical parameters of the simulation environment by adjusting the compression bag's inflation level. By varying the bag's volume, the system alters the available expansion space for the simulated lung, thereby changing the effective compliance parameter. This allows dynamic adjustment of lung compliance to match different clinical scenarios while maintaining physiological accuracy.

Function Achieved in This Case
The system provides a more realistic and comprehensive training experience, reducing the risk to patients and improving the effectiveness of patient care training by simulating various medical procedures accurately, thereby enhancing the skills of medical personnel.
Implementation Method 1
a second bag positioned within the lung compartment adjacent to the simulated lung, the second bag being inflatable and deflatable to occupy varying amounts of the maximum volume in order to control a simulated lung compliance of the simulated lung
Implementation Method 2
The simulated lung is inflatable and deflatable. The lung compartment defines an available volume for the simulated lung to expand into and the available volume is adjustable to control a compliance of the simulated lung

AI summary
A patient simulator system for teaching patient care is provided. The system includes a patient simulator. The patient simulator includes a patient body comprising one or more simulated body portions. The one or more simulated body portions include a lung compliance simulation system in some instances. In that regard, the lung compliance system is configured to be used with an external ventilator, including positive end-expiratory pressure (PEEP) and assisted-control ventilation. In some instances, the lung compliance system includes a lung compartment, a simulated lung positioned within the lung compartment, where the lung compartment defines an available volume for the simulated lung to expand into and where the available volume for the simulated lung to expand into is adjustable to control a compliance of the simulated lung.
