Saliva Sampling Device With Filtration Casing And Absorbent Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for obtaining saliva samples from animals, such as pigs, often result in inadequate quantity and quality due to contamination during sampling, which complicates subsequent veterinary examinations.
Innovation Solution
A receiving device with a core and casing, designed to absorb saliva through oral contact, allows for direct filtration and easy separation of contaminants, enabling a simple, fast, and hygienic method to obtain a filtered saliva sample suitable for immediate analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a receiving device without filtration is used to obtain saliva sample, then the sampling process is simple, but the sample quality deteriorates due to contamination
Solution Approach 1:
The receiving device is divided into two functional segments: a casing that filters contaminants and a core that absorbs saliva. This segmentation allows the device to simultaneously achieve simple operation and high sample quality by separating the filtration function from the absorption function.
Solution Approach 2:
The core is nested inside the casing, with the core being removable from the casing after sampling. This nested structure enables the core to be protected during sampling while allowing easy extraction of the contaminated core and retention of the filtered saliva sample.
2Manufacturing precision
If complex handling procedures are used to reduce contamination, then sample quality improves, but the sampling process becomes complex
Solution Approach 1:
The receiving device performs self-filtration during the sampling process itself. The casing automatically filters contaminants as saliva is absorbed by the core, eliminating the need for separate filtration steps or complex handling procedures in the laboratory.
Solution Approach 2:
Filtration is performed preliminarily during the sampling process itself, before the sample reaches the laboratory. The casing filters contaminants in advance, so that when the core is removed and the sample is extracted, it is already ready for analysis without requiring further processing.
3Manufacturing precision
If further processing of saliva sample is required in laboratory, then sample quality can be improved, but time and resources are lost
Solution Approach 1:
The device performs preliminary filtration and sample preparation at the sampling site, so that the sample is ready for direct analysis in the laboratory without requiring additional processing steps. This eliminates time loss and reduces laboratory workload.
Solution Approach 2:
The core containing the saliva sample is extracted from the casing after sampling. This extraction allows the sample to be directly transferred to laboratory analysis without requiring further processing, as the filtration has already been completed during sampling.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures a high-quality saliva sample with reduced contamination, facilitating direct analysis without further processing, thereby improving the efficiency and accuracy of veterinary examinations.
Implementation Method 1
The core (8) is configured to absorb more saliva (2) or sample material (11) than the casing (9)
Implementation Method 2
the sample material taken is separated from the receiving device, for example, by wringing out the receiving device
