Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing veterinary medical systems for small animals, particularly newborn puppies and kittens, are inadequate in clearing clogged breathing passages and stimulating respiratory efforts, often resulting in life-threatening situations due to their inefficiency and risk of causing harm.
Innovation Solution
A portable, hand-powered aspirator and resuscitator system comprising a piston-based suction pump and air supply pump, respectively, connected to masks that can be safely used to clear airways and stimulate breathing in newborn small animals, with features like flexible diaphragms for gentle suction and air supply, designed for non-invasive and controlled procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing veterinary medical systems are used for aspirating and resuscitating newborn small animals, then the procedures can be performed, but the systems are inefficient and pose significant risk of causing harm to the newborn
Solution Approach 1:
The patent applies parameter changes by providing controlled vacuum suction levels and air supply parameters through the piston-based pumps. The system allows adjustment of suction strength and air delivery to match the specific needs of newborn animals, preventing both insufficient clearance and excessive force that could cause harm. This controlled parameter delivery resolves the contradiction by ensuring safe operation while maintaining effectiveness.
Solution Approach 2:
The system incorporates feedback mechanisms where the veterinarian can observe the newborn animal's response to aspiration and resuscitation attempts. The hand-powered pumps allow real-time adjustment based on the animal's condition, enabling the operator to modulate suction and air supply according to actual physiological needs, thereby improving both safety and efficiency through adaptive control.
2Productivity
If strong vacuum suction is applied to clear clogged breathing passages, then aspiration effectiveness is improved, but the risk of causing harm to the newborn increases
Solution Approach 1:
The patent employs dynamics by using hand-powered piston pumps that allow variable suction strength rather than fixed high-power suction. The operator can dynamically adjust the suction intensity based on the specific case requirements, applying strong suction only when necessary and using gentler suction when the airways are less blocked, thus maintaining effectiveness while minimizing harm risk.
Solution Approach 2:
The system enables parameter changes in vacuum suction strength through the hand-operated pump mechanism. The veterinarian can modulate the suction parameter from weak to strong based on real-time assessment of the newborn's airway obstruction level, ensuring that sufficient suction is applied to clear blockages while avoiding excessive force that could cause tissue damage or distress.
3Power
If mechanical pumps are used for resuscitation, then air supply capability is improved, but the device complexity and risk of harm increase
Solution Approach 1:
The patent replaces complex electric or motorized pumps with simple hand-powered piston pumps for resuscitation. This mechanical substitution eliminates the need for power sources, control electronics, and complex mechanical drive systems, while still providing adequate air supply capability through manual operation. The simplicity of the hand pump reduces device complexity and associated risks while maintaining sufficient power for newborn resuscitation.
