Wherein, upper cover is the first hemispherical dome structure, and the second holding part and the second joint portion are positioned at respectively top and the lower limb of the first hemispherical dome structure.
Wherein, the top of upper cover is provided with sample tap, and sample tap is convenient to pipettor and is entered harvester inside to draw saliva sample, and harvester also comprises for sealing the gland bonnet of sample tap.
Wherein, the top of upper cover is provided with for defining the 3rd joint portion of sample tap, and the 3rd joint portion coordinates with gland bonnet.
Wherein, the height of upper cover is 1.5cm.
Wherein, the first holding part is the second hemispherical dome structure, and the first joint portion is the hollow circuit cylinder body structure being connected with the opening of the second hemispherical dome structure.
Wherein, the inside surface of the second joint portion is provided with internal thread, and the outside surface of the first joint portion is provided with external thread, external thread and screw-internal thread fit.
Wherein, cutting part comprises and is arranged at the coboundary of the first joint portion and with respect to two wedge angles of the axle center symmetry of the first joint portion.
Wherein, the height of the first holding part is 1.5cm.
Wherein, the height of the first joint portion is 1cm.
The beneficial effects of the utility model are: the situation that is different from prior art, the cutting part of the utility model harvester scratches sealing film the saliva preservation liquid in the second accommodation space is mixed with the saliva sample in the first accommodation space when upper cover coordinates with collection portion, in harvester, can hold more saliva sample, not only can meet experimental applications, and be convenient to depositing and moving of saliva sample.
Accompanying drawing explanation
Fig. 1 is the structural representation of the harvester preferred embodiment of the utility model saliva sample.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Refer to Fig. 1, Fig. 1 is the structural representation of the harvester preferred embodiment of the utility model saliva sample.In the present embodiment, harvester comprises collection portion 10, upper cover 20 and gland bonnet 30.
The top of upper cover 20 is further provided with sample tap 205, and sample tap 205 is convenient to pipettor and is entered harvester inside to draw saliva sample.Gland bonnet 30 is for sealing sample tap 205.Particularly, the top of upper cover 20 is provided with for defining 206, the three joint portions 206, the 3rd joint portion of sample tap 205 and coordinates with gland bonnet 30.Preferably, gland bonnet 30 and the 3rd joint portion 206 interference fit, so that gland bonnet 30 seals sample tap 205 completely, in other embodiments, gland bonnet 30 also can coordinate by other means with the 3rd joint portion 206.The diameter of sample tap 205 is 1～1.5cm.
Preferably, in the present embodiment, harvester is made by transparent plastic material.
It should be noted that in other embodiments, the size of each parts of harvester also can be set to other values as required.
The normal use flow process of the harvester of the present embodiment is: during collecting sample, gathered person's mouth parts a little, allows the saliva of nature secretion naturally flow into collection portion 10 through lower lip, keeps posture 5min, collects all salivas in 5min.Then the collection portion 10 that fills saliva sample is tightened by threaded engagement with upper cover 20, two wedge angles 1041,1042 scratch the sealing film 203 of upper cover 20 and saliva preservation liquid and saliva sample are mixed in the process along with tightening.Then harvester is turned upside down ten times, fully allow saliva sample and saliva preserve liquid and mix.When taking the saliva sample of collection, the gland bonnet 30 of turning on upper cover 20 tops is that available pipettor is drawn.
The first holding part 101 is hemispherical dome structure, and upper dimension is compared with large and bottom size is less, make the larger for holding on the first accommodation space 103 of saliva sample part cross-sectional area of its definition, and lower part cross-sectional area is less.Because part cross-sectional area on it is larger, facilitated the collection of saliva sample.When the saliva sample holding is less, because its bottom transverse sectional area is little, therefore still can keep the degree of depth of saliva sample, facilitate pipettor to sample the saliva sample in the first accommodation space 103.
Be different from the situation of prior art, the cutting part of the utility model harvester scratches sealing film the saliva preservation liquid in the second accommodation space is mixed with the saliva sample in the first accommodation space when upper cover coordinates with collection portion, in harvester, can hold more saliva sample, not only can meet experimental applications, and be convenient to depositing and moving of saliva sample.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model instructions and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
