Description

Technical Field

[0001] The utility model relates to the technical field of sample separation and extraction, in particular to a pathogenic microorganism sample separation and extraction device for testing. Background Art

[0002] Microorganisms are a group of tiny organisms that exist in nature. They are tiny in size, simple in structure, invisible to the naked eye, and can only be observed by magnifying them hundreds, thousands, or even tens of thousands of times with the aid of an optical or electron microscope. Pathogenic microorganisms refer to microorganisms that exist in water and can invade the human body, causing infection or even infectious diseases. They are also called pathogens. When extracting and testing some pathogenic microorganism samples, a centrifuge is often required to separate and extract the samples.

[0003] Prior art includes a utility model with publication number CN219314926U, which discloses a device for separating and extracting pathogenic microorganisms in water. The patent adopts a separation tank and an extraction tank, which are connected by a pipeline, a water inlet pipe is arranged at the top of the separation tank, and a separation mechanism is installed in the separation tank, a water outlet pipe is connected to one side of the extraction tank, and an extraction mechanism is arranged on the extraction tank; the extraction mechanism includes a vacuum pump and an aspirator, and the vacuum pump and the aspirator are both connected to the extraction tank by pipelines; the utility model solves the problem that, since the separation tank separates particulate matter from microorganisms by rotating centrifugation of a separation cylinder, and although larger particulate matter is filtered out in advance before separation, a large amount of particulate matter will continue to accumulate in the separation cylinder under continuous separation and extraction, which can easily lead to clogging or even damage of the filter screen on the separation cylinder, and the separation cylinder is inconvenient to disassemble and maintain, which greatly affects the separation efficiency of the device.

[0004] The inventors have found in their daily work that, in the process of stopping after separating the sample inside the test tube, the test tube is easy to fly out of the storage bin due to inertia, causing the test tube to break. Utility Model Content

[0005] The utility model aims to solve the defect that the test tube and the inner wall of the equipment are damaged by collision in the prior art, and proposes a pathogenic microorganism sample separation and extraction device for testing.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a device for separating and extracting pathogenic microorganism samples for inspection, comprising a centrifuge and a pressing device, a control panel is fixedly connected to the side of the centrifuge, a flap is rotatably connected to the surface of the centrifuge, a rotating placement plate is arranged on the inner wall of the centrifuge, a placement bin is arranged inside the rotating placement plate, the pressing device is arranged on the surface of the placement bin, the pressing device comprises a connecting plate and a rotating plate, the connecting plate is fixedly connected to the surface of the placement bin, the rotating plate is rotatably connected to the inner wall of the connecting plate, a stop block is fixedly connected to the lower surface of the rotating plate, a sliding hole is provided at one end of the rotating plate, and a limiting groove is provided on the side of the connecting plate.

[0007] Preferably, a sliding rod is fixedly connected to the inner wall of the sliding hole, and a resist rod is slidably connected to the surface of the sliding rod. The position of the resist rod can be restricted by the sliding rod inside the sliding hole, thereby reducing the situation in which the resist rod slides left and right when the device is in use, making it difficult to tightly connect the rotating plate and the connecting plate.

[0008] Preferably, the push rod is snap-fitted with the inner wall of the limiting groove, and the limiting groove is provided to facilitate limiting the push rod.

[0009] Preferably, a first spring is fixedly connected to the surface of the push rod, and one end of the first spring away from the push rod is fixedly connected to the inner wall of the sliding hole. The first spring is provided to facilitate applying a restoring elastic force to the push rod.

[0010] Preferably, the inner wall of the placement bin is provided with a lifting device, the lifting device includes a supporting block and a test tube, the test tube is provided on the inner wall of the placement bin, the supporting block is slidably connected to the inner wall of the placement bin, a sponge pad is fixedly connected to the upper surface of the supporting block, the water pipe is combined with the surface of the sponge pad, and by providing the supporting block inside the placement bin, the test tube can be lifted, thereby reducing the situation where the test tube falls into the placement bin when the equipment is in use and cannot be taken out quickly.

[0011] Preferably, a limiting groove is provided inside the placement bin to facilitate limiting the second spring.

[0012] Preferably, a second spring is fixedly connected to the lower surface of the support block, and one end of the second spring away from the support block is fixedly connected to the inner wall of the limiting groove.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when using the device, the experimenter places the sample to be separated inside the test tube, then places the test tube and the inside of the placement bin, then covers the flap and the surface of the centrifuge, then starts the device, rotates the placement plate to drive the placement bin to rotate at high speed, and separates the sample inside the test tube. When using the device, the user slides the push rod, and then the movement of the push rod drives the first spring to displace and deform to generate elastic force, and then the push rod is separated from the inside of the limiting groove, the rotating plate loses its restraint, and the rotating plate is rotated to drive the push block to move away from the top of the test tube. By setting a pressing device, the test tube is effectively restricted, which plays a role in restricting the test tube and reduces the speed of the device when it is in use. When the device drives the test tube to rotate at high speed and is about to end, the speed of the test tube decreases. At the moment of stopping, the test tube is easily flown out of the inside of the placement bin by inertia, and the test tube collides with the inside of the device, causing the test tube to break, thereby improving the stability of the device.

In the utility model, by providing a lifting device, when the user moves the rotating plate away during use of the device, the second spring resets and drives the support block to move, and when the support block moves, it drives the sponge pad to move upward, and when the sponge pad moves upward, it pushes the test tube to move, and then one end of the test tube is exposed to the interior of the placement bin. By providing a lifting device, the test tube is effectively lifted, which plays a role in lifting the test tube, reduces the situation that when the device is in use, the experimenter places the test tube into the interior of the placement bin, and when separating the sample in the test tube, the experimenter needs to take the test tube out of the placement bin, and the test tube is completely immersed in the interior of the placement bin, making it difficult to take out the test tube, thereby improving the practicability of the device.

[0023] The specific arrangement and function of the pressing device 6 and the lifting device 7 will be described in detail below.

[0024] In this embodiment: the pressing device 6 is arranged on the surface of the placement bin 5, and the pressing device 6 includes a connecting plate 61 and a rotating plate 62. The connecting plate 61 is fixedly connected to the surface of the placement bin 5, and the rotating plate 62 is rotatably connected to the inner wall of the connecting plate 61. A stop block 63 is fixedly connected to the lower surface of the rotating plate 62. A sliding hole 65 is opened at one end of the rotating plate 62, and a limiting groove 64 is opened on the side of the connecting plate 61.

[0025] Specifically, a sliding rod 68 is fixedly connected to the inner wall of the sliding hole 65 , and a resisting rod 66 is slidably connected to the surface of the sliding rod 68 .

[0026] In this embodiment: the position of the push rod 66 can be limited by the sliding rod 68 inside the sliding hole 65, thereby reducing the situation where the push rod 66 slides left and right when the device is in use, making it difficult to tightly connect the rotating plate 62 and the connecting plate 61.

[0027] Specifically, the push rod 66 is engaged with the inner wall of the limiting groove 64 , and the limiting groove 64 is installed to facilitate limiting the push rod 66 .

[0028] Specifically, a first spring 67 is fixedly connected to the surface of the push rod 66 , and one end of the first spring 67 away from the push rod 66 is fixedly connected to the inner wall of the sliding hole 65 . The first spring 67 is provided to facilitate applying a restoring elastic force to the push rod 66 .

[0029] In this embodiment: the inner wall of the placement bin 5 is provided with a lifting device 7, the lifting device 7 includes a supporting block 73 and a test tube 71, the test tube 71 is provided on the inner wall of the placement bin 5, the supporting block 73 is slidably connected to the inner wall of the placement bin 5, a sponge pad 74 is fixedly connected to the upper surface of the supporting block 73, and a water pipe is combined with the surface of the sponge pad 74. By arranging the supporting block 73 inside the placement bin 5, the test tube 71 can be lifted, thereby reducing the situation where the test tube 71 falls into the placement bin 5 when the equipment is in use and the test tube 71 cannot be taken out quickly.

[0030] In this embodiment, by providing a support block 73 inside the storage bin 5, the test tube 71 can be lifted, thereby reducing the possibility that the test tube 71 falls into the storage bin 5 when the device is in use and cannot be quickly taken out.

[0031] Specifically, a limiting groove 72 is provided inside the placement bin 5 , and the limiting groove 72 is provided to facilitate limiting the second spring 75 .

[0032] Specifically, a second spring 75 is fixedly connected to the lower surface of the support block 73 , and one end of the second spring 75 away from the support block 73 is fixedly connected to the inner wall of the limiting groove 72 . The second spring 75 is provided to facilitate applying a restoring elastic force to the support block 73 .

[0033] Working principle: When using the equipment, the experimenter places the sample to be separated inside the test tube 71, then places the test tube 71 and the inside of the placement bin 5, then covers the flap 2 and the surface of the centrifuge 1, then starts the equipment, rotates the placement plate 4 to drive the placement bin 5 to rotate at high speed, and separates the sample inside the test tube 71. When using the equipment, the user slides the push rod 66, and then the push rod 66 moves to drive the first spring 67 to displace and deform to generate elastic force, and then the push rod 66 is separated from the inside of the limiting groove 64, the rotating plate 62 loses its restraint, and the rotating plate 62 is rotated to drive the push block 63 to move away from the top of the test tube 71. By setting the pressing device 6, the test tube 71 is effectively restricted, which plays a role in restricting the test tube 71 and reduces the speed of the equipment when it is in use. When the equipment drives the test tube 71 to rotate at high speed and is about to end, the speed of the test tube 71 decreases. At the moment of stopping, the test tube 71 easily flies out of the inside of the placement bin 5 by inertia, and the test tube 71 collides with the inside of the equipment, causing the test tube 71 to break, thereby improving the stability of the equipment.

[0034] When the device is in use, when the user moves the rotating plate 62 away, the second spring 75 is reset and drives the support block 73 to move. When the support block 73 moves, it drives the sponge pad 74 to move upward. When the sponge pad 74 moves upward, it pushes the test tube 71 to move, and then one end of the test tube 71 is exposed to the interior of the placement bin 5. By setting the lifting device 7, the test tube 71 is effectively lifted, which plays a role in lifting the test tube 71, reducing the situation when the device is in use. When the experimenter places the test tube 71 into the interior of the placement bin 5 and separates the sample in the test tube 71, the experimenter needs to take the test tube 71 out of the placement bin 5. The test tube 71 is completely immersed in the interior of the placement bin 5, which makes it difficult to take out the test tube 71, thereby improving the practicability of the device.
