When the device is used, the sampling device is used for collecting and sampling saliva in the oral cavity of a patient and scraping and sampling oral mucosa. After the patient gargles, sample bag 2 can be deposited in storage box 18, the independent packaging, directly put into the patient mouth after tearing, then the patient can close the mouth, for example patient can wear the gauze mask this moment, especially when having respiratory disease infectious risk, the patient can do the action of chewing to sample bag 2, be favorable to promoting the secretion of saliva, simultaneously when utilizing tooth to extrude sample bag 2 repeatedly, sample bag 2 is the repeated action of compression release, sample bag 2 self has the elasticity resilience ability, in the release process, self inside production negative pressure, the saliva in the oral cavity is absorb to accessible thief hole 6, the setting up of adsorbing cotton 5 is convenient for save saliva, it can be the line ball form to adsorb cotton 5, thief hole 6 diameter can be less, for example two millimeters in diameter. When needs scrape the oral mucosa and get, can be with the help of permanent magnet 4, 4 upper ends of permanent magnet cup joint isolation gum cover 8, barrier paper 3 is put on patient face one side, barrier paper 3 is disposable, then paste isolation gum cover 8 on barrier paper 3, the patient pushes sample bag 2 to 3 one sides of barrier paper, permanent magnet 4 is adsorbable to sample bag 2 this moment, patient face is pressed from the centre, can be at first push sample bag 2 to the tooth outside by the patient, adsorb down at magnetic force, sample bag 2 hugs closely on the oral mucosa, then isolation gum cover 8 keeps the laminating with the face, remove permanent magnet 4, then can drive sample bag 2 and scrape the oral mucosa, latticed sample strip 7 can improve the scraping ability, be adapted to any direction of scraping, latticed shape is convenient for persist the sample of scraping simultaneously. After the sample was accomplished, the patient can tell sample bag 2, can tell to keep apart gum cover 8 on, is adsorbed the location by permanent magnet 4, avoids dropping, then medical personnel can put into detection device with sample bag 2 and detect. The sampling capsule 2 can be placed in the reagent tube 9 and then the sampling capsule 2 is scraped off the isolating rubber sleeve 8 by a lateral movement and falls into the reagent tube 9.
The detection device is inverted, the detection box 10 is arranged on the upper portion, diluent in the reagent tube 9 is prevented from flowing out, the reagent tube 9 is detached from the connecting tube 15 and is placed into the sampling capsule 2, then the reagent tube 9 is hermetically connected with the connecting tube 15, and the sealing column 16 is hermetically matched with the inner lower portion of the reagent tube 9, so that sample preservation or culture can be realized. After the connection of the reagent vessel 9 is completed, the cassette 10 is again brought down and the reagent vessel 9 is brought up. The connecting portion of reagent pipe 9 and connecting pipe 15 is the stereoplasm material, and the rest is soft material, for example soft silica gel etc. can extrude sample bag 2 through extrusion reagent pipe 9, makes the sample fully mix with the diluent. Usable test paper 11 detects at last, there is the compression space between support ring 17 and the connecting pipe 15 upper end, namely the soft part of reagent pipe 9, medical personnel can pinch support ring 17 from the outside and extrude downwards, utilize support ring 17 compression sealing post 16, the pjncture needle can slowly pierce sealing post 16 upper portion this moment, the pjncture needle pierces through sealing post 16 after, continue to push down sealing post 16, can spill through-hole 14 of dropping liquid needle tubing 12, dropping liquid needle tubing 12 and the inside intercommunication of reagent pipe 9 this moment, can press in the application of sample department of test paper 11 through dropping liquid tubing 12 with a small amount of sample diluent through pressing, waiting time detects can, see through the transparent part in detection box 10 upper end, can observe test paper 11 detection zone. Because the dropping needle tube 12 is thin, and the detection box 10 is arranged in a closed manner and occupies the internal volume, excessive sample adding can not be caused. After the sample is added on the test paper 11, the reagent tube 9 is not extruded, the support ring 17 is released and is not pressed down, the sealing column 16 recovers under the self elastic recovery performance, the puncture needle and the dropping liquid needle tube 12 enter the sealing column 16 again, the puncture needle is thin, the destructiveness to the sealing column 16 is small, the puncture needle withdraws from the rear shell to recover, meanwhile, after the puncture needle returns to the sealing column 16, the sealing performance of the sealing column 16 is further ensured, and sample diluent in the reagent tube 9 can be stored. There is no need to immediately dispose of medical waste.
The isolation paper 3 is a disposable article, and the isolation rubber sleeve 8 is a single-use article, and can be reused after being sterilized or treated according to medical waste according to medical regulations.
The diluent stored in the reagent tube 9 may be other reagents necessary for sample processing.
Can connect on the sample bag 2 and set up protection rope 19, protection rope 19 is short but expose outside patient's oral cavity, but does not influence the patient and close the mouth, cup joints on the protection rope 19 and sets up protection film 20, can supply handheld the holding to hold and hold, can also directly hold between the fingers protection film 20 at last and place the sample bag 2 in the reagent pipe 9, can cut protection rope 19, also can put into the kit with protection rope 19 simultaneously, but protection film 20 breaks away from protection rope 19, and protection film 20 is according to medical waste treatment.
The end face of the isolation rubber sleeve 8 is contacted with the sampling capsule 2, and the end face can be set to be concave, so that the sampling capsule 2 can be conveniently received, and the outflow of sample saliva can be reduced.
When the invention is used, samples can be stored in the whole detection process and after detection, the reagent tube 9 can be stored for a long time, the label 21 can be arranged on the reagent tube 9 for identification, detection objects are not easy to mix, and the detection box 10 can be not marked.
The test paper 11 is arranged in the detection box 10 in a sealed mode, so that the storage effect is better, and the failure is not easy to occur. If the sample is invalid, the reagent tube 9 is only required to be matched with a new detection box 10 again, and the sample diluted liquid is dropped into the test paper 11 for detection according to the steps.
If a dark light environment is needed in the detection process, the positioning seat 22 can be arranged in a closed manner for the box body, after the detection box 10 is inserted, the interior of the detection box can be in a dark light or non-light environment, and the observation result is taken out after the detection time elapses.
