CLP Mannequin Simulator for Safe Medical Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current training methods for medical professionals and caregivers in managing cleft lip and palate (CLP) patients are hindered by the risks associated with practicing on real newborns, including airway obstruction and the need for repeated procedures, which lengthens the learning curve and limits opportunities for consistent training due to the rarity of cases and unique challenges of each patient.
Innovation Solution
A highly realistic mannequin simulator, the Advanced Training System Mannequin Simulators with cleft lip and palate (AMACS), replicates the anatomical features of a newborn with CLP, allowing for repeated practice of procedures such as intraoral and nasal impression taking, device placement, and removal, thereby reducing the learning curve and eliminating risks associated with working on real patients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real newborn patients are used for training procedures, then authentic clinical experience is gained, but safety risks increase due to airway obstruction and other complications
Solution Approach 1:
The patent creates a hyper-realistic mannequin simulator that replicates the anatomical features, tissue consistency, and physiological responses of a newborn infant with cleft lip and palate. This copy allows trainees to practice impression taking, device placement, and other procedures on a model that feels and behaves like a real patient, eliminating safety risks while maintaining training authenticity
Solution Approach 2:
The mannequin simulator serves as an intermediary between theoretical knowledge and real patient care. It provides a safe intermediate step where trainees can develop skills before working with actual patients, reducing the harmful effects of inadequate training while preserving the benefits of hands-on experience
2Productivity
If repeated procedures are performed on real patients for training purposes, then skill development is accelerated, but patient exposure to multiple procedures increases risks and ethical concerns
Solution Approach 1:
The simulator can be used repeatedly without risk to patients. Trainees can perform multiple impression taking procedures, device placements, and removals on the same mannequin as many times as needed, accelerating skill development without exposing real patients to repeated interventions
Solution Approach 2:
The mannequin is pre-configured with anatomical features and can be reset between procedures, allowing trainees to practice the complete sequence of steps multiple times in advance before encountering real patients, thereby improving competence without additional patient risk
3Object-affected harmful factors
If training programs wait for availability of real CLP patients, then training remains ethically safe, but training consistency decreases due to rarity and uniqueness of each case
Solution Approach 1:
The mannequin provides a consistent, repeatable training model that is always available. Unlike real patients whose cases vary uniquely, the simulator can be reset to the same anatomical configuration, allowing all trainees to practice identical procedures under identical conditions, ensuring consistent training quality
Solution Approach 2:
The simulator serves multiple training functions simultaneously - it can be used for impression taking practice, device placement training, removal procedures, and even teaching anatomical variations. This universal applicability ensures consistent training availability regardless of patient case availability
4Reliability
If the learning curve is extended due to limited training opportunities, then more careful patient selection is possible, but training duration increases and delays competent practice
Solution Approach 1:
The realistic mannequin allows extensive practice without time loss. Trainees can rehearse procedures repeatedly until mastery is achieved, compressing the learning curve from months or years of waiting for patient opportunities into weeks or days of intensive simulator training, thereby reducing delay without compromising patient care quality

AI summary
The present innovation relates to an Advanced Training System Mannequin Simulators of a complete newborn baby with facial and intraoral features of the CLP malformation, AMACS. It is intended for use in medical training of dental professionals, doctors, emergency medical support personnel and parents or caregivers. Furthermore, it can be adopted in several common therapies and in maneuvers such as intraoral impressions. It can also be used by any other person who requires a model simulator to learn the anatomy, practice procedures or surgery of the lip, nose and palate. The invention avoids unsettling a real newborn patient for training proposes. This mannequin simulator, as an innovative training resource, significantly shortens the learning curve of the trainees, since the procedures can be repeated over and over again. The AMACS comprises: (a) trunk and limbs, having as reference the weight and height of a real newborn, (b) a complete head (skull, face and neck), having as reference the facial and intraoral features of the CLP malformation, (c) the anatomy of the lips, nose, oral and nasal cavities with the actual dimensions and proportions of a newborn with CLP deformity. The most remarkable feature is a very accurate representation of the entire body but, in particular, the oral and facial anatomical features of a newborn with CLP deformity, thus allowing for a high-level and realistic training experience. In the facial and intraoral region of the mannequin the lips, tongue, cheeks, maxillary segments, palatal rugae, labial and lateral frenulum, nasal cavity, palate, hemi uvulae, tongue and lingual frenulum, columella, nostrils, alar cartilage, dome and nasal tip are faithfully reproduced. On the outer surface of the mannequin the skin, the route of the veins, the relief of the ribs and clavicles are also scrupulously represented. The mannequin may include the alteration of one or more anatomical parts to simulate the different types of congenital anomalies that affect the facial and intraoral region. One or more parts of the mannequin simulator may be disposable or replaceable. The careful design of the AMACS follows the process of: (a) computed tomography, scan, or photogrammetry images of the full skull and face of a human newborn with CLP; (b) generating the cleft lip and palate based on a three-dimensional reconstruction of the buccal area. The manufacture process involves methods independent and indispensable but not in sequence: (a) parts made by injection of polymer-based material; b) parts made by 3D printing, and (c) assembly. Both body and head are perfectioned using realistic painting techniques.
