Fig. 2 is the structural representation of saliva save set described in the utility model embodiment 1.
Embodiment
To better illustrate the purpose of this utility model, technical scheme and advantage, below in conjunction with specific embodiment to this
Utility model is described further.
Embodiment 1
A kind of embodiment of saliva collection save set described in the utility model, is filled as shown in figure 1, being pre-processed including saliva
Put includes hollow body 3, aperture and is more than the mistake of saliva excretion body diameter with saliva save set, the saliva pretreatment unit
Filter membrane 2 and infusing device, the filter membrane 2 are located at the inside of the hollow body 3, and the infusing device is used for the mistake
The saliva of the liquid feeding side of filter membrane 2 is pushed into the tapping side of the filter membrane 2, the saliva save set and the hollow body 3
Bottom connect to preserve the saliva come out from the tapping side of the filter membrane 2.
