Description

Gum detection device

The present invention relates to a detection device, in particular to a detection device that detects whether the gums are inflamed through an optical method.

Gingivitis is an early symptom of periodontal disease. It is caused by teeth that are not cleaned, so that the gingival margin and adjacent surfaces of the teeth will accumulate plaque for a long time. The bacteria in the plaque will secrete toxins to stimulate the gums and cause inflammation of the gums. If it persists, it may further deteriorate into severe periodontitis.

There is a ring-shaped sulcus at the junction of teeth and gums called gingival sulcus. When periodontal disease causes damage, the gingival sulcus will deepen, which is called periodontal pocket at this time. At present, gingivitis is mainly detected by contact with periodontal probes. The most widely used periodontal probe is the Michigan O probe, which is marked with 1 to 1 along the axial direction at the tip. With a scale of 10, the dentist will insert the tip of the probe into the patient’s gingival sulcus and measure the depth of the gingival sulcus through the scale. The depth of a healthy gingival sulcus is generally 1 to 3 mm. When the depth is greater than 3 mm, it means a tooth has been formed. Peripheral capsular bag, the deeper the depth, the more serious the periodontal damage. However, when this kind of probe is operated, it is necessary to go deep into the gingival sulcus and read the scale. Not only is the operation time-consuming and often makes the patient uncomfortable, there may also be errors in the way of reading the visual scale, and the accuracy needs to be improved.

Therefore, the purpose of the present invention is to provide a fast, comfortable and accurate gum detection device.

Therefore, the new type of gum detection device includes a main body unit, a detection unit arranged on the main unit and suitable for abutting the gums, and a processing unit arranged in the main unit and signal-connected with the detection unit. The detection unit can emit a light source with a wavelength range of 400 to 800 nanometers to the gums, and receive it after the light source is diffusely reflected on the gums to obtain the spectral information after the diffuse reflection. The processing unit is used to analyze the spectral information received by the detection unit, and obtain the change in the oxygen content of the gum blood based on the spectral information, and finally obtain the health status of the gums according to the change in the oxygen content of the gum blood.

The effect of the present invention is that because there are many capillaries distributed in the gums, when the gums are inflamed or damaged, the oxygen content in the blood vessels and blood will change. The present invention obtains the spectral information of the diffuse reflection of the light source on the gums through the detection unit. The processing unit can compare the relationship between the spectral information and the oxygen content of the gums according to the data stored in advance, thereby obtaining the oxygen content of the blood of the patient's gums, and then obtaining the inflammation or damage of the gums. The new type detection is fast and can greatly reduce the interference of human factors, effectively improve the convenience and accuracy, and the at least one optical fiber probe does not need to go deep into the gingival sulcus, which can avoid patient discomfort.

Referring to Figure 1, Figure 2, and Figure 3, an embodiment of the new type of gum detection device includes a main body unit 1, a detection unit 2 provided in the main unit 1, and a processing set in the detection unit 2 Unit 3. The main body unit 1 includes a main casing 11 and a handle 12 extending downward from the main casing 11 and held by a user.

The detection unit 2 includes a plurality of optical fiber probes 21 detachably inserted on the main housing 11 and extending forward, and a plurality of light sources 22 located in the main housing 11 and corresponding to the optical fiber probes 21, respectively, And a spectrometer 23 arranged in the main housing 11 and corresponding to the optical fiber probes 21. Each optical fiber probe 21 can be expanded and contracted relative to the main housing 11, and this function can be achieved by arranging a spring or other mechanism. The optical fiber probe 21 extends outward when it is not pressed against the gums, and when the optical fiber probe 21 is pressed against the gums, the optical fiber probe 21 is affected by the reaction force and retracts inward into the main housing 11. The design enables the optical fiber probes 21 arranged in a row to simultaneously adapt to different concave and convex irregular dentitions, ensuring that the optical fiber probes 21 can be pressed against the gums of multiple teeth respectively as shown in FIG. 2. Each optical fiber probe 21 surrounds and defines two adjacent transmitting channels 211 and a receiving channel 212 facing the spectrometer 23. Each light source 22 has two light-emitting modules 221 respectively aligned with the sending channels 211 of a corresponding optical fiber probe 21. The light-emitting modules 221 can be halogen lamps or light-emitting diodes, and can generate light sources with wavelengths ranging from 400 nm to 800 nm. It should be noted that the spectrometer 23 corresponds to the receiving channels 212 of the optical fiber probes 21 at the same time.

The processing unit 3 includes an analysis module 31 arranged in the main housing 11 and connected to the spectrometer 23 in signal, a signal connected to the analysis module 31 and exposed behind the main housing 11 (in contrast to the optical fiber probes 21. The display 32 at the insertion location) and a control interface 33 arranged on the main housing 11 and used to control the light sources 22 and the display 32. The control interface 33 can be a plurality of physical buttons, but can also be a touch screen combined with the display 32.

The method of use of this embodiment is as follows: first extend the optical fiber probes 21 into the patient's oral cavity, and make the optical fiber probes 21 respectively touch the gums of the plural teeth as shown in FIG. 2. Then operate the control interface 33 to start the light sources 22, so that the light sources 22 output light sources with a wavelength range of 400 nm to 800 nm (preferably 500 nm) through the transmission channels 211. The aforementioned light sources will be Diffuse reflection is performed on the gingiva A of the teeth, and the light source after diffuse reflection is returned to the spectrometer 23 from the receiving channels 212. The spectrometer 23 can analyze the diffuse reflection spectrum information of each optical fiber probe 21 to obtain each gingiva Spectral information corresponding to A (different gingiva corresponds to different spectral information). The spectral information obtained by the spectrometer 23 is sent to the analysis module 31 for comparison. The database of the analysis module 31 stores the correspondence between the spectral information and the oxygen content changes in the blood (and blood vessel B) in the gum A. , And the corresponding relationship between the changes in the blood oxygen content of the gums and the health of the gums. Finally, the analysis module 31 obtains the oxygen content change of the blood in the patient's gums based on the spectral information transmitted by the spectrometer 23, and then judges the health of the gums based on this, and displays the result on the display 32 The above is for review results. Refer to Figures 4 and 5. Figure 4 shows the information spectrum of healthy gums, and Figure 5 shows the information spectrum of unhealthy gums.

The new model can quickly detect the gums in a non-invasive optical way without piercing the gingival sulcus without the presence of professionals such as dentists, and monitor the changes in blood oxygen content in the capillaries of the gums by analyzing the spectral information, thereby confirming whether the gums are Inflammation or damage, quickly understand whether the patient has gingivitis or periodontal disease, through the design of the spectrometer 23 to monitor without visual scale, not only can reduce the interference of human factors, the patient can even self-test without the assistance of others.

It should be further explained that when this embodiment is in operation, the light emitting modules 221 project light sources to the transmitting channels 211 in sequence, and enter the receiving channel 212 after diffuse reflection. This detection method can be Compare the two spectral information to improve the accuracy and achieve the effect of reconfirmation. Of course, each optical fiber probe 21 can also have one transmitting channel 211 and two receiving channels 212, so that each light source 22 has only one light emitting module 221, and the light emitting module 221 is projected by the transmitting channel 211. Later, the diffusely reflected light sources will sequentially enter the receiving channels 212, so that the effects of comparison and repeated confirmation can also be achieved.

Referring to Figure 1, Figure 2, and Figure 6, what needs to be added is that the optical fiber probes 21 can also be replaced with the shape corresponding to the posterior tooth region C (only one or two can be replaced) as required. This optical fiber probe 21 As shown in FIG. 6, there is a straight pipe section 213 retractable into the main housing 11, and an elbow section 214 bent and extended outward from the straight pipe section 213, through which the elbow section 214 can extend into the posterior teeth. The position of area C (such as posterior molars, etc.) is against the gingiva of the posterior area C so that different positions of the dentition can be detected. The straight pipe section 213 can be retracted into the main housing 11 to maintain the optical fiber probe The telescopic function of 21 enhances the versatility and convenience of the new model.

In summary, by analyzing the relationship between the spectral information and the oxygen content of the gums, the present invention can know whether the gums are inflamed and damaged. The detection process does not require other human intervention, avoids the interference of human factors, and does not require professional expertise. The presence of people to assist or operate, lower the barriers to use and allow patients to self-test, so it can indeed achieve the purpose of cost and new style.
