Infant CPR Training Apparatus with Rotatable Head and Airway Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CPR training methods for infants are limited by their two-dimensional nature and lack of simulation, failing to effectively teach the specific posture requirements for infant CPR, which differ from adult CPR, particularly in head tilting to open or close the airway.
Innovation Solution
A CPR training apparatus for infants featuring a rotatable head portion with a tunnel and airway system that opens the airway only when tilted slightly and closes it in neutral or excessively tilted positions, mimicking the correct posture for infant CPR, including a chin frame for proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If two-dimensional education methods (display education or booklets) are used for CPR training, then the training can be easily delivered, but the learning effect is limited and cannot effectively teach trainees the specific posture requirements for infant CPR
Solution Approach 1:
The patent creates a physical copy/model of an infant's head and airway structure that trainees can interact with. The training apparatus includes a head portion with a tunnel representing the airway, allowing trainees to practice proper head tilting and airway management techniques on a realistic model rather than viewing static images
Solution Approach 2:
The patent transitions from two-dimensional display education to three-dimensional physical modeling. The head portion, tunnel portion, and airway tube create a 3D representation that allows trainees to understand spatial relationships and perform manual manipulation skills required for infant CPR
2Ease of operation
If the head portion is kept in a neutral state during training, then the structure is simple and easy to operate, but the airway remains closed and cannot simulate the correct CPR technique for opening the airway
Solution Approach 1:
The patent makes the head portion rotatable relative to the body portion, allowing dynamic adjustment of the head angle. The neutral closure portion and hyperextension closure portion respond dynamically to head positioning, opening or closing the airway tube based on the degree of head tilt, thus simulating the actual physiological response during CPR
Solution Approach 2:
The patent changes the angular parameter of head tilting to control airway status. By rotating the head portion to specific angles (slight tilt vs. hyperextension), the airway tube transitions between open and closed states, teaching trainees the precise angular control needed for effective infant CPR
3Productivity
If the airway tube remains always open, then air flow is always possible, but it cannot teach trainees the critical skill of understanding when and how the airway opens or closes based on head position
Solution Approach 1:
The patent incorporates a feedback mechanism where the head position directly controls airway tube status. When trainees tilt the head incorrectly (hyperextension), the hyperextension closure portion blocks the airway tube, providing immediate tactile and visual feedback that the technique is wrong. When the head is tilted correctly, the airway opens, confirming proper technique

AI summary
A cardiopulmonary resuscitation (CPR) training apparatus for infants is disclosed. The CPR training apparatus for infants includes a body portion, a head portion including a head frame rotatably connected to the body portion, a tunnel portion including a tunnel frame installed on a neck of the body portion, and a lower catching protrusion extending from a lower side of the tunnel frame to an upper side of the tunnel frame, an airway portion including an airway tube installed to be in communication with a mouth of the head portion, and a neutral closure portion connected to an outside of the airway tube so as to be positioned above the lower catching protrusion, and a tube portion configured to connect the airway tube and an artificial lung to each other by passing through the tunnel portion between the lower catching protrusion and the neutral closure portion. The neutral closure portion may be in contact with the lower catching protrusion to close the tube portion when the head portion is in a neutral state with respect to the body portion, and the neutral closure portion may be spaced apart from the lower catching protrusion to open the tube portion when the head portion is tilted at a predetermined angle or more with respect to the body portion.
