Description

Technical Field

[0001] The present invention belongs to the technical field of microorganism detection, and in particular relates to a pathogenic microorganism detection device. Background Art

[0002] Detection of pathogenic microorganisms is an important means of clinical diagnosis, epidemiological investigation and public health management, aiming to quickly and accurately identify the source of infection. The principle of fluorescence detection of microorganisms is mainly based on the characteristics of fluorescence signals. The sample is illuminated by a specific excitation light. When the light beam hits the sample, the microorganisms in the sample will absorb part of the light energy, causing specific molecules in the microorganisms to be in an excited state. When the excited state molecules return to the ground state, they will release the absorbed energy in the form of fluorescence. At this time, the photodetector will collect and detect the fluorescence signal emitted from the sample. The photodetector will convert the fluorescence signal into an electrical signal, which is then amplified and processed and finally converted into a digital signal, thereby realizing qualitative and quantitative analysis of the microorganisms.

[0003] Currently, when using a fluorescence detector to detect pathogenic microorganisms, a test tube containing a sample reagent and a fluorescent dye is generally inserted directly into the fluorescence detector, and then the fluorescence detector is started to detect the pathogenic microorganisms in the sample in the test tube. Although direct detection can also detect and analyze the pathogenic microorganisms in the sample, the fluorescent dye and the sample reagent are not evenly mixed, and the existing detector can only perform a single test, and the detection position cannot be changed, which may lead to a decrease in the accuracy of the detection of pathogenic microorganisms in the sample reagent. Based on this, a pathogenic microorganism detection device is proposed. Summary of the Invention

[0015] The beneficial effects of the present invention are: 1. The present invention uses a lifting mechanism and a clamping mechanism in combination.

[0018] 4. The present invention uses a rotating mechanism and a knocking mechanism in conjunction. When the rotating mechanism rotates the test tube, the test tube will drive the turntable to rotate, and then the turntable will rotate. The rotation of the turntable will cause the push rod to intermittently push the push block to slide outward, and then the knocking ball will intermittently knock the test tube, causing the test tube to shake. The shaking of the test tube will cause the reagent in the test tube to shake, so that the sample reagent and the fluorescent dye are further mixed, changing the state of the reagent in the test tube, thereby further improving the quality and accuracy of fluorescence detection of pathogenic microorganisms.

The photodetector 702 records the fluorescent signal emitted by the sample to be tested, thereby detecting pathogenic microorganisms in the sample reagent. The data obtained from the test is displayed through the control panel 2, and the relevant data can be printed out through the printer 3. After the test is completed, the cover 5 is opened and the test tube can be taken out.

[0024] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the pathogenic microorganism detection device also includes: a partition mechanism 6 fixedly connected to the detection groove 9, the partition mechanism 6 includes a fixed plate 601 fixedly connected to the detection groove 9 by bolts, a partition 602 is fixedly connected to the bottom of the fixed plate 601, a through hole 603 is opened on the top of the fixed plate 601, and a plurality of partitions 602 are provided to divide the detection groove 9 into multiple detection chambers.

[0025] When in use, the partition 602 separates the multiple detection cavities to avoid mutual interference between the lights in each detection cavity, thereby ensuring the accuracy of detection.

[0026] like Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the pathogenic microorganism detection device also includes: a lifting mechanism 8 fixedly connected to the detection tank 9, and the multiple detection cavities in the detection tank 9 are fixedly connected with the lifting mechanism 8, the lifting mechanism 8 also includes a servo motor 801 installed at the bottom of the detection tank 9, the output end of the servo motor 801 is fixedly connected to a lifting screw 802, the top of the lifting screw 802 is rotatably connected to the bottom of the fixed plate 601, the lifting screw 802 passes through the lifting ring 803 and is connected to the lifting ring 803 by a thread, and the lifting screw 802 can drive the lifting ring 803 to rise and fall in the detection tank 9, and a limited slide bar 804 is fixedly connected in the detection tank 9, and the top of the limited slide bar 804 is connected to the fixed plate 60 1 is fixedly connected to the bottom of the lifting ring 803, the limiting slide bar 804 passes through the lifting ring 803 and is slidably connected to the lifting ring 803; a clamping mechanism 10 for clamping the test tube is provided in the lifting ring 803, and the clamping mechanism 10 includes a rotating ring 1005 rotatably connected to the inner surface of the lifting ring 803, the inner surface of the rotating ring 1005 is fixedly connected to the sliding bin 1001, the inner surface of the sliding bin 1001 is slidably connected to the slide 1002, a clamping spring 1003 is installed in the sliding bin 1001, and the two ends of the clamping spring 1003 are respectively fixedly connected to the slide 1002 and the rotating ring 1005, the end of the slide 1002 is fixedly connected to the clamping ring 1004, and the top of the clamping ring 1004 is inclined to facilitate the insertion of the test tube.

[0027] When in use, a test tube containing sample reagents and fluorescent dye is inserted between the clamping rings 1004. At this time, the clamping ring 1004 will clamp the test tube through the slide 1002, the slide 1001 and the clamping spring 1003. After the light emitter 701 is started, the servo motor 801 can be started, so that the servo motor 801 drives the lifting screw 802 to rotate, and then the lifting ring 803 moves up and down slowly under the limiting action of the limiting slide 804 and the rotation of the lifting screw 802. The slow up and down movement will drive the test tube to move up and down slowly through the rotating ring 1005, the sliding bin 1001, the sliding plate 1002, the clamping spring 1003 and the clamping ring 1004. When the test tube moves downward so that the middle and upper layers of the reagent in the test tube are between the light emitter 701 and the photodetector 702, the servo motor 801 stops rotating, the test tube is allowed to stand for a few minutes, and then the light emitter 701 and the photodetector 702 are started. The light emitted by the light emitter 701 can illuminate and detect the middle and upper layers of the reagent in the test tube. The light of a specific wavelength emitted by the light emitter 701 is irradiated onto the sample to be tested. The sample to be tested emits a fluorescent signal that falls on the photodetector 702. The photodetector 702 records the fluorescent signal emitted by the sample to be tested, thereby performing a first detection on the pathogenic microorganisms in the sample reagent. When the test tube moves upward and the middle and lower layers of the reagent in the test tube are between the light emitter 701 and the photodetector 702, the servo motor 801 stops rotating, and the test tube is allowed to stand for a few minutes. The light emitter 701 and the photodetector 702 are then started through the control panel 2. The light emitted by the light emitter 701 can illuminate and detect the middle and upper layers of the reagent in the test tube. The light of a specific wavelength emitted by the light emitter 701 is irradiated onto the sample to be tested. The sample to be tested emits a fluorescent signal that falls on the photodetector 702. The photodetector 702 records the fluorescent signal emitted by the sample to be tested, thereby performing a second detection on the pathogenic microorganisms in the sample reagent. The light emitted by the light emitter 701 can illuminate all the reagents in the test tube, achieving two detections and improving the detection accuracy.

[0028] like Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the pathogenic microorganism detection device also includes: a rotating mechanism 11 rotatably connected to the lifting mechanism 8, the rotating mechanism 11 includes a gear ring 1104 fixedly connected to the outer surface of the rotating ring 1005, the outer surface of the gear ring 1104 is meshed with a gear 1101, both ends of the gear 1101 are rotatably connected to the inner surface of the lifting ring 803, the inner surface of the gear 1101 is fixedly connected to a limiting slide 1102, the outer surface of the lifting screw 802 is provided with a limiting slide 1103, the limiting slide 1102 is slidably connected to the limiting slide 1103, and the lifting screw 802 passes through the gear 1101 and is slidably connected to the gear 1101.

[0029] During use, when the lifting screw 802 rotates, it will drive the gear 1101 to rotate through the limiting slide groove 1103 and the limiting slide 1102, and then drive the gear ring 1104 to rotate. The rotation of the gear ring 1104 will drive the test tube to rotate slowly through the rotating ring 1005, the sliding bin 1001, the slide plate 1002, the clamping spring 1003 and the clamping ring 1004, so that the test tube can rotate slowly during the slow up and down movement, so that the sample reagent in the test tube can be evenly mixed with the fluorescent dye, and the light can irradiate the reagent in the test tube twice at different angles and heights, obtaining two different detection data for the upper and lower layers of the reagent in the test tube, thereby further improving the accuracy of the detection and making the data obtained by the detection more convincing.

[0030] like Figure 3 、 Figure 6 and Figure 7 As shown, the pathogenic microorganism detection device also includes: a knocking mechanism 12 fixedly connected to the bottom of the lifting mechanism 8, the knocking mechanism 12 includes a fixed frame 1201 fixedly connected to the bottom of the lifting ring 803, a rotating seat 1202 is rotatably connected to the top middle position of the fixed frame 1201, a clamping rubber 1203 is fixedly connected to the rotating seat 1202, a push rod 1204 is fixedly connected to the outer surface of the rotating seat 1202, a plurality of push rods 1204 are provided, and are arranged in an equidistant annular array along the outer surface of the rotating seat 1202, a through slot 1210 is opened on the fixed frame 1201, and a knocking slide rod is slidably connected in the through slot 1210 1207, one side of the knocking slide 1207 is fixedly connected with a knocking ball 1208, the knocking ball 1208 is made of rubber material, which can avoid breaking the test tube, one side of the knocking slide 1207 is fixedly connected with a push block 1209, the push rod 1204 and the push block 1209 are arranged in the same plane, and the ends of the push rod 1204 and the push block 1209 are both arranged in an arc shape, the other side of the knocking slide 1207 is fixedly connected with a telescopic rod 1205, the outer surface of the telescopic rod 1205 is provided with a knocking spring 1206, and the two ends of the knocking spring 1206 are respectively fixedly connected to the knocking slide 1207 and the fixed frame 1201.

[0031] When inserting the test tube, the bottom of the test tube is inserted into the rotating seat 1202, and is in close contact with the clamping rubber 1203 in the rotating seat 1202. The clamping rubber 1203 squeezes and clamps the bottom of the test tube. At this time, the test tube is in close contact with the knocking ball 1208, and when the test tube rotates, the test tube will drive the rotating seat 1202 to rotate. The rotation of the rotating seat 1202 will cause the push rod 1204 to intermittently push the push block 1209 to slide outward. When the push rod 1204 pushes the push block 1209 to slide outward, the knocking slide bar 1207 will be pushed inward along the through slot 1210 under the action of the push block 1209. The push rod 1204 is separated from the push block 1209, and the knocking slide bar 1207 will slide inward under the action of the compressed knocking spring 1206, thereby causing the knocking ball 1208 to knock on the test tube, causing the test tube to shake. The shaking of the test tube will cause the reagent in the test tube to shake, causing the sample reagent to further mix with the fluorescent dye, changing the state of the reagent in the test tube, thereby further improving the quality and accuracy of fluorescence detection of pathogenic microorganisms.

[0032] The specific working principle of the present invention is as follows: During use, the cover 5 is opened and the test tube containing the sample reagent and the fluorescent dye is placed in the detection tank 9. The test tube containing the sample reagent and the fluorescent dye is inserted between the clamping rings 1004. At this time, the clamping rings 1004 will clamp the test tube through the slide 1002, the slide 1001 and the clamping spring 1003. At the same time, the bottom of the test tube is inserted into the rotating seat 1202 and tightly fits against the clamping rubber 1203 in the rotating seat 1202. The clamping rubber 1203 squeezes and clamps the bottom of the test tube. At this time, the test tube is tightly fit against the knocking ball 1208. Then, the cover 5 is closed and the servo motor 801 is started through the control panel 2, so that the servo motor 801 drives the lifting screw 802 to rotate, thereby causing the lifting ring 803 to slowly move downward under the limiting action of the limiting slide 804 and the rotation of the lifting screw 802. The slow downward movement of the lifting ring 803 will drive the test tube to slowly move downward through the rotating ring 1005, the sliding bin 1001, the slide plate 1002, the clamping spring 1003 and the clamping ring 1004. At the same time, when the lifting screw 802 rotates, it will drive the gear 1101 to rotate through the limiting slide groove 1103 and the limiting slide 1102, thereby driving the gear ring 1104 to rotate. The rotation of the gear ring 1104 will drive the test tube to slowly rotate through the rotating ring 1005, the sliding bin 1001, the slide plate 1002, the clamping spring 1003 and the clamping ring 1004, thereby causing the test tube to slowly rotate during the slow downward movement, so that the sample reagent in the test tube can be evenly mixed with the fluorescent dye; During this process, during the rotation of the test tube, since the clamping rubber 1203 is tightly attached to the bottom of the clamped test tube, the rotation of the test tube will simultaneously drive the rotation of the swivel seat 1202, and the rotation of the swivel seat 1202 will cause the push rod 1204 to intermittently push the push block 1209 to slide outward. When the push rod 1204 pushes the push block 1209 to slide outward, the knocking slide bar 1207 will slide outward along the through slot 1210 under the action of the push block 1209, compressing the telescopic rod 1205 and the knocking spring 1206, and causing the knocking ball 1208 to separate from the test tube. When 204 is separated from the push block 1209, the knocking slide bar 1207 will slide inward under the action of the compressed knocking spring 1206, thereby causing the knocking ball 1208 to knock the test tube, causing the test tube to shake. The shaking of the test tube will cause the reagent in the test tube to shake, causing the sample reagent and the fluorescent dye to further mix, changing the state of the reagent in the test tube, thereby further improving the quality and accuracy of fluorescence detection of pathogenic microorganisms. In this process, when the test tube moves downward to the upper middle layer of the reagent in the test tube between the light emitter 701 and the photodetector 702, The servo motor 801 stops rotating, and the test tube is allowed to stand for a few minutes. Then the light emitter 701 and the photodetector 702 are started. The light emitted by the light emitter 701 can illuminate and detect the middle and upper layers of the reagent in the test tube. The light of a specific wavelength emitted by the light emitter 701 is irradiated on the sample to be tested. The photodetector 702 records the fluorescent signal emitted by the sample to be tested, thereby performing the first detection of pathogenic microorganisms in the sample reagent. The data obtained by the detection is displayed on the control panel 2. Then the servo motor 801 is started in the opposite direction to rotate the lifting screw 802, thereby causing the lifting screw 802 to rotate. The ring 803 moves upward slowly, and the knocking mechanism 12 works synchronously during the test tube's ascent until the lower middle layer of the reagent in the test tube is between the light emitter 701 and the photodetector 702. The servo motor 801 stops rotating, and the test tube is allowed to stand for a few minutes. The light emitter 701 and the photodetector 702 are then started. The light of a specific wavelength emitted by the light emitter 701 is irradiated onto the sample to be tested, and the photodetector 702 records the fluorescent signal emitted by the sample to be tested, thereby performing a second test for pathogenic microorganisms in the sample reagent. The test data is displayed on the control panel 2. The two data obtained from the test are displayed on the control panel 2, and the control panel 2 calculates the average value of the two data to determine the situation of the pathogenic microorganisms in the reagent, and can print out the relevant data through the printer 3. After the test is completed, the light emitter 701 and the photodetector 702 are turned off, and the servo motor 801 is started in reverse to rotate the lifting screw 802, thereby causing the lifting ring 803 to slowly move upward until the lifting ring 803 rises to the highest initial position, and the cover 5 is opened to take out the test tube.

[0033] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
