[0001] The present invention relates to the technical field of medical devices, and specifically to a dental caries early warning detection device and method. Background Art

[0002] In the prior art, dental caries detection mainly relies on professional examinations by dentists, including using tools such as oral mirrors and probes for examination, as well as using imaging means such as X-rays. However, these detection methods often require professional medical equipment and personnel for operation, the detection process is relatively complex, and there is a certain radiation risk, which is not convenient for frequent use in daily life. In addition, for children, these detection means may cause fear and discomfort to them, affecting the smooth progress of the detection.

[0003] Although the existing simple detection devices have a fast detection procedure, they are complex to operate, time-consuming and consumptive of materials. At the same time, the post-treatment process of the collected saliva is cumbersome and inconvenient to operate. Therefore, it is of great practical significance to develop an early childhood dental caries detection kit that is simple to operate, has fast and accurate result judgment, and can be used by non-professionals. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems that in the existing daily life, the prevention of dental caries is not in place, children are afraid of seeing a doctor, it is inconvenient to see a doctor, the time and effort are wasted in dental caries diagnosis, the cost is high and the time is long, and the collected saliva cannot be stored, and to provide a dental caries early warning detection device and method to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: a dental caries early warning detection device, including a detection device body, a chamber bacteria observation mechanism is provided in the middle of the detection device body, and the chamber bacteria observation mechanism is composed of a bacteria observation chamber and a biological filter membrane arranged in the bacteria observation chamber; one side of the chamber bacteria observation mechanism is connected to a sample collection mechanism through a long groove, and the sample collection mechanism is composed of a telescopic device arranged in a square hole in the collection area and a sampling strip connected to one end of the telescopic device; a detection mechanism is arranged on the other side of the chamber bacteria observation mechanism, and the detection mechanism is composed of a plurality of detection holes and detection test papers arranged at the bottom of the detection holes.

[0006] Further, the sampling strip passes through the square hole in the collection area and is connected to the telescopic device.

[0007] Further, a plurality of holes are provided on the biological filter membrane, and the diameter of the holes is 0.43 um.

[0008] Further, a plurality of liquid introduction holes communicating with the detection mechanism are opened at the bottom of the bacteria observation chamber on the side close to the detection holes, and the liquid introduction holes are communicated with the detection holes through a liquid introduction channel.

[0009] Further, a liquid return groove is formed at the bottom on one side of the bacterial observation chamber close to the sample collection mechanism, and one end of the liquid return groove communicates with the deep groove at the bottom of the groove-shaped hole in the sample collection area.

[0010] Further, one end of the long groove communicates with the central groove on the sample collection mechanism, and a squeezable transparent plastic film is arranged at the top of the central groove for squeezing out the saliva sample in the sampling strip.

Step 2: The user holds the sampling strip in the mouth for 30s - 60s to make the sampling strip completely wet. Step 3: Pull the telescopic device to make the sampling strip return to the position of the central groove. Step 4: By squeezing the transparent plastic film at the top of the central groove, the saliva is discharged from the sampling strip to the maximum extent. The extruded saliva enters the bacterial observation chamber through the long groove, and is processed by the biological filter membrane in the bacterial observation chamber, so that the biological metabolites enter the liquid introduction channel through the liquid introduction hole, and then enter the detection hole through the liquid introduction channel and soak the test paper. Step 5: After the saliva enters the biological filter membrane, most of the cocci and bacilli will be blocked by the filter membrane and form a precipitate. By using a magnifying glass or a microscope to observe whether the micropores of the biological filter membrane inside the bacterial observation chamber become dark, the number of bacteria in the oral cavity can be roughly judged according to the number of dark holes. Step 6: By observing the color change of the test paper in the detection hole, it can be judged whether the oral cavity environment is healthy.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following elaborates on the preferred embodiments of the present invention in conjunction with the drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0020] Embodiment, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown in the figure, the present invention provides a dental caries early warning detection device, which includes a detection device body 9. A chamber bacteria observation mechanism is provided in the middle of the detection device body 9. The chamber bacteria observation mechanism consists of a bacteria observation chamber 12 and a biological filter membrane 3 arranged in the bacteria observation chamber 12; one side of the chamber bacteria observation mechanism is connected to a sample collection mechanism through a long groove 11. The sample collection mechanism consists of a telescopic device 2 arranged in a square hole 13 in the collection area and a sampling strip 1 connected to one end of the telescopic device 2. A detection mechanism is arranged on the other side of the chamber bacteria observation mechanism. The detection mechanism consists of a number of detection holes 5 and a test strip 10 arranged at the bottom of the detection holes 5.

[0021] The sampling strip 1 passes through the square hole 13 in the collection area and is connected to the telescopic device 2.

[0022] A number of holes are provided on the biological filter membrane 3, and the diameter of the holes is 0.43um. While the liquid is passing through, it allows biological metabolites to enter the detection area. At the same time, it is used to prevent cocci and bacilli from entering the subsequent device. The biological filter membrane 3 is located in front of the liquid inlet hole 4. Its function is to filter out most of the cocci and bacilli (because the subsequent detection index is the metabolite of microorganisms, and microorganisms are not needed). At the same time, once the cocci and bacilli bind to the holes on the filter membrane, when observed under the instrument, there will be a change in brightness and darkness.

[0023] A number of liquid inlet holes 4 communicating with the detection mechanism are provided at the bottom on one side of the bacteria observation chamber 12 close to the detection holes 5. The liquid inlet holes 4 are connected to the detection holes 5 through a liquid inlet channel 8.

[0024] A liquid return groove 6 is provided at the bottom on one side of the bacteria observation chamber 12 close to the sample collection mechanism. One end of the liquid return groove 6 is connected to a deep groove 7 at the bottom of the trough-shaped hole in the sample collection area.

[0025] One end of the long groove 11 is connected to a central groove 14 on the sample collection mechanism. A squeezable transparent plastic film is provided at the top of the central groove 14 for squeezing out the saliva sample in the sampling strip 1.

[0026] A dental caries early warning detection method is implemented using the above dental caries early warning detection device. The specific steps are as follows: Step 1: Press the telescopic device 2 (the telescopic device is a stretching rod, and the sampling strip is connected to the stretching rod. By moving the pushing rod, the purpose of extending and retracting can be achieved), and extrude the sampling strip 1, as Figure 2 shown; Step 2: The user holds the sampling strip 1 in the mouth for 30s - 60s to make the sampling strip 1 completely wet; Step 3: Pull the telescopic device 2 to make the sampling strip 1 return to the position of the central groove 14, as Figure 3 shown; Step 4: By squeezing the transparent plastic film at the top of the central groove 14, the saliva is discharged from the sampling strip 1 to the greatest extent. The squeezed saliva enters the bacterial observation chamber 12 through the long groove 11, and is processed by the biological filter membrane 3 in the bacterial observation chamber 12, so that the biological metabolites enter the liquid introduction channel 8 through the liquid introduction hole 4, and then enter the detection hole 5 through the liquid introduction channel 8 and soak the test strip 10; the excess biological metabolites separated after the saliva enters the biological filter membrane 3 will flow back to the deep groove 7 through the liquid return groove 6; Step 5: After the saliva enters the biological filter membrane 3, most of the cocci and bacilli will be blocked by the filter membrane and form a precipitate. The user uses a magnifying glass or a microscope to observe whether the micropores of the biological filter membrane 3 inside the bacterial observation chamber 12 become dark, and roughly judge the number of bacteria in the oral cavity according to the number of dark holes. Step 6: By observing the color change of the test strip 10 in the detection hole 5, the concentration of some metabolites in the oral cavity can be judged. According to the metabolite concentration-color change table, as Figure 8 shown, non-professionals can judge whether the oral environment is healthy.

[0027] The above embodiments only express the implementation modes of the present invention, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
