AI Technical Summary
In existing sputum samplers, the sampling head comes into contact with the patient's saliva during the sampling process, causing bacteria from the saliva to contaminate the sampling head and affecting the accuracy of sputum test results.
A sputum sampler was designed, comprising a protective tube and an extraction component. The protective tube prevents saliva from contaminating the sampling head, and the extraction component ensures the sealing and convenience of the sampling process through the cooperation of a sealing plug and a squeezing plate.
It effectively avoids the influence of saliva on sputum testing, improves the accuracy of sputum testing and the convenience of the sampling process, and reduces the risk of external bacteria contaminating sputum.
