[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , an oral fluid collection device for oral examination, including a hollow tube 1. An inlet 6 is provided in the upper part of the tube wall of the hollow tube 1. A plurality of first fixing strips 3 are fixedly connected to the inner wall of the hollow tube 1, and a collection tube 4 is fixedly connected among the plurality of first fixing strips 3. A flow guide ring 5 is fixedly connected to the upper inner side of the hollow tube 1, and the flow guide ring 5 is in contact with the collection tube 4. Through the flow guide ring 5, it is convenient for the saliva sample to enter the collection tube 4. A snap ring 12 is fixedly connected to the inner wall of the collection tube 4, and the snap ring 12 and the collection tube 4 are of an integral structure. Through the setting of the snap ring 12 and the cooperation with the annular groove on the rubber stopper 10, the rubber stopper 10 can be limited after entering the collection tube 4.

[0021] Please refer to Figure 3 , Figure 4 , a push rod 7 is slidably connected to the upper end inside the hollow tube 1. A second fixing strip 9 is fixedly connected to the bottom of the push rod 7, and a rubber stopper 10 is fixedly connected to the bottom of the second fixing strip 9. An annular groove is provided on the outer side of the rubber stopper 10. A button 8 is fixedly connected to the top of the push rod 7, and a corrugated sleeve 11 is fixedly connected to the bottom edge of the button 8. The corrugated sleeve 11 is fixedly connected to the hollow tube 1. Through the setting of the button 8, it is convenient to push the push rod 7.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3, a protective mechanism 2 is provided on the outer side of the hollow tube 1. Through the setting of the protective mechanism 2, it has a protective effect on the saliva collection process and avoids contamination of the saliva sample. The protective mechanism 2 includes a funnel 21 slidably sleeved on the outer side of the hollow tube 1. A guide frame 22 is fixedly connected to the lower part of the outer side of the funnel 21. A guide block 23 is fixedly connected to the middle part of the outer side of the hollow tube 1. The guide frame 22 is slidably connected to the guide block 23. A spring 24 is provided inside the guide block 23. One end of the spring 24 is fixedly connected to the guide frame 22, and the other end of the spring 24 is fixedly connected to the inner surface of the guide block 23. Through the setting of the spring 24, the reaction force can act on the funnel 21 through the guide frame 22.

[0023] The specific implementation process of the present utility model is as follows: When in use, first cover the funnel 21 outside the patient's mouth, and then push the whole body. The funnel 21 is driven by the reaction force of the mouth to drive the guide frame 22 into the guide block 23. At this time, the funnel 21 exposes the liquid inlet 6 on the hollow tube 1. Then guide the patient to spit out saliva. The saliva enters the hollow tube 1 through the liquid inlet 6 after being guided by the funnel 21, and then enters the collection tube 4 under the guidance of the diversion ring 5. Subsequently, remove the thrust on the whole body. The funnel 21 resets under the action of the spring 24 and blocks the liquid inlet 6. Then push the push rod 7 through the button 8. The push rod 7 drives the rubber plug 10 to move downward through the second fixing strip 9, so that the rubber plug 10 slides into the collection tube 4. When the annular groove on the rubber plug 10 is level with the snap ring 12 on the collection tube 4, the rubber plug 10 is restricted by the snap ring 12. Then pull up the button 8 to break the second fixing strip 9, and the rubber plug 10 stays in the collection tube 4. Then screw the collection tube 4 from the bottom to break each first fixing strip 3, and then the collection tube 4 can be taken out. In this way, during the whole process of saliva collection, the saliva is not contaminated, thus ensuring the cleanliness of the sample.

[0024] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
