Referring to the first, second and third figures, the present invention is a disposable objective lens comprising: a main body portion 10 having a first end surface 11, a second end surface 12, a housing 13 and a housing The first end surface 11 has a central reference point 11A (as shown in the fourth figure) for coating a sample 91 (see the twelfth figure); the receiving portion 14 is located at the first end surface 11 An optical lens assembly 20 is disposed in the accommodating portion 14 for generating an optical magnification. The magnification is about 800 to 1300 times depending on actual needs. A light-emitting cover 30 is a hemispherical shell shape; and a plurality of light-emitting tube portions 31 and a light-lighting control portion 32 are provided; each of the light-emitting tube portions 31 is fixed to the light-emitting cover 30, The light-receiving control unit 32 is configured to control the plurality of light-emitting tube portions 31 for light-receiving; and an image capturing portion 40 is adjacent to the second end surface 12 for A target image 911 of the sample 91 is captured through the optical lens assembly 20 (see FIGS. 15A and 15B).

In practice, the first end surface 11 has a central convex portion 111 having a convex height H, and the central reference point 11A is located at a central position of the central convex portion 111; the central convex portion 111 facilitates the main body The portion 10 is coated with the specimen 91 (as shown in the eleventh and twelfth figures); at least one engaging portion 112 (as shown in the fifth figure).

Referring to the sixth and seventh aspects, the lighting cover 30 has a corresponding engaging portion 33 corresponding to the engaging portion 112, and the engaging corresponding portion 33 is configured to be engaged by the engaging portion during the engaging process. 112 is pushed (refer to FIG. 7B) and then reset (refer to FIG. 7C), and the engaging portion 112 is engaged with each other.

The second end surface 12 is a light transmissive convex structure, and the target image 911 can be captured.

The plurality of light-emitting tube portions 31 are fixed to the light-emitting cover body 30 in a substantially radial distribution, and are respectively lighted toward the central reference point 11A at a specific working angle thereof.

Each of the light-emitting tube portions 31 is provided with at least one light guiding element 311 which is connected and controlled by the light-lighting control unit 32. For example, a plurality of (4) of the light-emitting tube portions 31 can be disposed. The light guiding element 311 (as shown in the eighth figure) respectively emits red (R) light, blue (B) light, and green (G) light (as shown in the ninth figure, which indicates that both red and blue light are emitted simultaneously Green light) and ultraviolet light (UV) (as shown in the tenth figure).

Thereby, the light control unit 32 can selectively emit one or all of the red (R) light, the blue (B) light, and the green (G) light (or selectively emit ultraviolet light) according to actual needs.

Of course, in the case of a cell or a compound that partially emits ultraviolet light, it may be further changed to emit only ultraviolet light, so that the fluorescent substance A, B, and C can be seen from the sample 91. (See Figure 16) for the convenience of testing.

The manner of use of this case is illustrated here. Suppose the sample of the case 91 If it is blood, the main body portion 10 can be picked up, and the central convex portion 111 of the first end surface 11 contacts the specimen 91. Since the central reference point 11A is located on the arc convex surface of the central convex portion 111, the center can be made The central reference point 11A is easily adhered to the specimen 91.

Then, the light-emitting cover 30 is covered on the first end surface 11 of the main body portion 10. This portion can guide the engaging corresponding portion 33 and the engaging portion 112 to each other, and quickly snap-fit and fix. Of course, a bump may be added to the first end surface 11 of the main body portion 10, and a corresponding recess portion is added to the light-emitting cover body 30, and the two phases are engaged (the male-female engagement is a well-known technology, and It can be achieved), and it also has the effect of fixing and aligning.

Finally, the image capturing portion 40 is moved to the second end surface 12 of the main body portion 10.

Then, the lighting control unit 32 selects the position, angle, color type, and light intensity of the light to be polished.

For example, the two light-emitting tube portions 31 located at the first working angle θ 1 and the second working angle θ 2 (as shown in FIG. 13 ) are controlled to be illuminated toward the specimen 91 (red light, green light, Blue light or ultraviolet light can be controlled according to actual needs). However, if the angle of illumination (as shown in Figure 14A) is such that the captured target image 911 (as shown in Figure 15A) is unable to confirm whether the object D is two due to a dead angle. Or one time, you can change (add) other working angles to light (as shown in Figure 14B), you can match the light of different angles to judge that the object D is actually two (such as the fifteenth Figure B shows).

Of course, the aforementioned sample 91 may also be human or animal saliva, body fluid, sample liquid to be tested, or other liquid sample to be detected.

Taking saliva as an example, using a specific reagent in combination with the corresponding spectral light, it is possible to Accurate tests such as AIDS, pregnancy and multiple drugs.

The advantages and effects of the present invention can be summarized as follows:

[1] There are many types of lighting and can be replaced at will, and the light intensity can be finely adjusted. In the present invention, a plurality of light guiding elements can be disposed in each of the light-emitting tube portions, and at least four kinds of commonly used light sources such as red light, green light, blue light and ultraviolet light can be simultaneously set, or a customized special spectrum can be selected according to requirements. light source. You can choose a single light color to illuminate, or mix a variety of colors to illuminate at the same time, or you can choose a single UV light to illuminate, and further choose the light intensity. Different lighting methods can produce different image capturing effects, all according to actual needs. Transform. Therefore, there are many types of lighting and the effect is good.

[2] The lighting angle can be freely controlled to improve image recognition. Each of the light-punching tube portions of the present invention is designed to be evenly distributed on the light-emitting cover body at different working angles, and the light-emitting tube portions of different angles can be activated to light the sample body according to requirements, and can be plurally different. Angles capture clear target images, and then analyze the software and reconstruct high-resolution real images. Therefore, the lighting angle can be freely controlled to improve image recognition.

[3] The detection operation is quite simple. As long as the main body portion of the corresponding detection application is taken out, the central convex portion (that is, the position where the central reference point is located) is taken, and then the main body portion, the light-emitting cover body and the image capturing portion are connected, and the subsequent follow-up can be automatically performed. The detection operation, that is, the three steps of collecting the sample, combining, and starting the detection. Therefore, the detection operation is quite simple.

[4] Abandonable to reduce the chance of being infected. The main body of the present invention is disposable, and the purpose of collecting a sample detection is to reduce the probability of infection due to contact with the virus by the cleaning device. Of course, if the cost permits, it can be mass-produced and all disposable devices. Therefore, it can be discarded to reduce the chance of being infected.

[5] A large number of sampling tests can be performed. If you have a need, you can have questions about most of them. A large number of sampling, it is also possible to carry out a large range of qualitative or quantitative inspection standard sampling operations at the same time, in order to improve the correctness of the test results.
