In above-described embodiment, the dilution of reservoir 11 can be placed quantitatively, and amount and the aseptic collection cotton 25 of dilution are adopted
The saliva amount of collection matches.Aseptic collection cotton 25 can be used the sterile sponge of medical grade and be made, and dilution can be phosphate buffer,
After material, the size of aseptic collection cotton 25 are fixed, the saliva of oral cavity secretion, the saliva that aseptic collection cotton 25 is adsorbed are come into full contact with
Liquid measure substantially constant, therefore the saliva collecting device of the embodiment can realize quantitative collection saliva and dilution saliva.
In actual application, tapered portion 13, the soft column 14 of sealing and stud 15 can be integrally formed to form sealing element, liquid storage
The reservoir 11 of device 1 is inverted, and a certain amount of dilution is added in reservoir 11, then by the tapered portion 13 and liquid storage of sealing element
The hand-held part 12 of device 1 is close to fix, while sealing element is integrally by reservoir exit seal.
Steps are as follows for the use of saliva collecting device in the present embodiment:
Step 1: the tail portion of acquisition rod 2 is plugged in the grafting chamber 16 of liquid storage device 1, holds hand-held part 12, by acquisition rod
The aseptic collection cotton 25 on 2 heads is put into the cavity sidewalls or sublingual in oral cavity, is sufficiently soaked with saliva；
Step 2: in the collection tube 31 that the head insertion mixer 3 of the acquisition rod 2 after saliva will be acquired, and by liquid storage device 1
Stud 15 be screwed into collection tube tail portion so that the inner ring of the bicyclic strainer 32 in the head flange 23 of acquisition rod 2 and collection tube 31
Protrusion 323 abuts against, so that the aseptic collection cotton 25 being located in the groove 24 of acquisition rod 2 is limited in groove 24 and bicyclic strainer
Between 32 bottom, the saliva in aseptic collection cotton 25 is extruded the bottom that collection tube 31 is flowed into from inner ring filter opening 321；
Step 3: gently breaking the soft column 14 of sealing in liquid storage device 1, the position for being located at reservoir exit until sealing soft column 14
It is broken, the dilution in reservoir 11 is flowed down along the barred body 21 of acquisition rod 2, and is flowed from the outer ring filter opening 322 of bicyclic strainer 32
The bottom for entering collection tube 31, jiggling collection tube 31 makes dilution and saliva be uniformly mixed to form saliva test sample；
Step 4: the rotation of nut 4 being covered at hollow stud 311 is removed, the reservoir of liquid storage device 1 is gently squeezed
11, suitable saliva test sample is squeezed out for detecting from the outlet of collection tube 31.
Embodiment two
Saliva collecting device provided by the embodiment is improvement on the basis of embodiment one, with one structure phase of embodiment
Which is not described herein again for same content.The embodiment and one structure of embodiment are the difference is that remove the soft column of sealing of sealing element
14, soft column 14 will be sealed and replaced with plastic film, and add outside reservoir 11 a hard upper cover (such as rigid plastics
Lid), upper cover can be connected on hand-held part 12, the advantage of doing so is that it is more convenient to use, it can be operated with one hand, without double
Hand cooperation, it is time saving and energy saving, while avoiding and sealing the plastic residues that soft 14 breaking part of column may be fallen down, pollute dilution and to be measured
Saliva；When not in use, upper cover is covered, preventing from accidentally touching or squeeze reservoir 11 makes film breaks.
The use step of the embodiment and embodiment one the difference is that, in step 3, without breaking disconnected hose when use,
Reservoir 11 is gently squeezed after upper cover need to only be removed, i.e., film is crushed using internal pressure, flows out dilution, remaining step and implementation
Example one is essentially identical.
Obviously, the saliva collecting device of above-described embodiment, however it is not limited to the acquisition of saliva, it can also be used to urine, sweat, nose
The acquisition of the body fluid such as tears, sputum, but above-described embodiment is more suitable for the accurate acquisition of thick saliva.
The utility model saliva collecting device collection process is easy, reduces manual operations amount, and safety and sanitation reduce detection sample
The contaminated probability of product；Since dilution is sealed in reservoir 11, by fracture from outside seal soft column 14 or squeeze make it is thin
Film fracture, dilution enters time collection tube 31 along the barred body 21 of acquisition rod 2 by the outer ring filter opening 322 of bicyclic strainer 32, and inhales
It invests the saliva on aseptic collection cotton 25 and is squeezed from the inner ring filter opening 321 of bicyclic strainer 32 and enter collection tube 31, the two difference
31 bottom of collection tube is flowed by non-interfering channel, prevents saliva wall built-up from remaining, influences quantitative collection, while avoiding people
Body directly contacts dilution and saliva.
Test case
It is matching criterion according to dilution and the ratio 9:1 of prepare liquid saliva, is made properly using the sterile sponge of medical grade
The aseptic collection cotton 25 of size, saliva uptake allow to have appropriate error, are 100 microlitres of positive and negative 10 microlitres of quantitative collections；Liquid storage
900 microlitres of phosphate buffers are stored in capsule 11.Aseptic collection cotton 25 is put into moisten in tester mouthful and draws saliva, will then be adopted
In the collection tube 31 of the head insertion mixer 3 of acquisition rod 2 after collecting saliva, and the stud of liquid storage device 1 15 is screwed into collection tube
Tail portion, after then removing liquid storage device 1, acquisition rod 2 and nut 4, by saliva collected in collection tube 31 be transferred to centrifuge tube or
In other clean containers, then is drawn and measured with pipettor.
Different sexes, age, totally 20 person-times of tester of physical qualification are tested, collected saliva is weighed, is obtained
Numerical value is as follows:
Average value is 98.8 μ l after 20 bit test persons acquire saliva.It can be seen that the accuracy ratio of present apparatus quantitative collection
It is higher.
It will be appreciated by those skilled in the art that these embodiments are merely to illustrate the utility model, without limitation, this is practical new
The range of type, the various equivalent variations and modification made to the utility model belong to the utility model disclosure.
