Description

Technical Field

[0001] The invention relates to the technical field of microbial testing, in particular to a microbial separation device for clinical microbial testing. Background Art

[0002] Microorganisms are a general term for a class of organisms, including bacteria, viruses, fungi, etc., covering many types of beneficial and harmful species. They are widely involved in many fields such as food, medicine, industry and agriculture, environmental protection, sports, etc., and are closely related to humans. In the process of testing microorganisms, it is usually necessary to separate the microorganisms to facilitate subsequent testing.

[0003] The patent document with publication number CN115433666A discloses a microorganism separation device for microorganism inspection, including a main body, an upper outer surface of the main body is fixedly connected to a motor, a lower outer surface of the motor is rotatably connected to a rotating shaft, an upper outer surface of the main body is fixedly connected to a feeding port near the left side, a lower end of the feeding port is fixedly connected to a through pipe, a lower inner surface of the main body is fixedly connected to a base, an upper outer surface of the base is rotatably connected to a separation box, an outer surface of the separation box is fixedly connected to a bearing near the upper end, and an upper outer surface of the bearing is fixedly connected to a feed hopper.

[0004] In the above application documents, the microbial sample and a certain amount of sterile water are poured into the feeding port, and then the motor is started to drive the rotating shaft to rotate. The rotating shaft drives the stirring plate to rotate to stir the microbial sample and sterile water inside the placement tank. When the rotating shaft continues to rotate, the fixed plate will move downward so that the telescopic rod will begin to shorten in the feed hopper. When the telescopic rod moves to the slot, the fixed plate is stuck because there is no thread under the outer surface of the rotating shaft. As the rotating shaft continues to rotate, the fixed plate and the telescopic rod will drive the separation box to start rotating at the feed hopper bearing and the base to perform centrifugal separation. In this process, it is difficult to control the time for stirring and mixing the microbial sample and the sterile water. The centrifugal separation may begin before the microbial sample and the sterile water are completely mixed, which is not conducive to the subsequent microbial separation effect. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a microorganism separation device for clinical microbiological testing, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a microorganism separation device for clinical microbiological testing, comprising a bin body, a closed door is provided at the front end of the bin body, a top cover is fixedly installed on the top of the bin body by bolts, a feed pipe is passed through and fixedly connected to the top of the top cover, a lower hopper is fixedly connected to the interior of the bin body, and a stirrable separation mechanism is provided at the bottom of the interior of the bin body; the stirrable separation mechanism comprises a rotating column and a motor, the bottom of the rotating column is rotatably connected to the inner bottom of the bin body, the top of the rotating column is fixedly connected to a centrifugal bin, and the surface of the centrifugal bin is passed through and fixedly connected to a connecting Tube, a filter is provided inside the connecting tube, an end of the connecting tube away from the centrifugal bin passes through and is fixedly connected to the separation bin, a card slot is provided on the inner wall of the centrifugal bin, the motor is fixedly installed on the top of the top cover, the motor is fixedly connected to the rotating shaft through its output shaft, the bottom of the rotating shaft is fixedly connected to a stirring head, a long rod is fixedly connected to the surface of the rotating shaft, a groove is provided at one end of the long rod away from the rotating shaft, a telescopic spring is provided inside the groove, an arc-shaped card block is slidably connected to the inside of the groove through the telescopic spring, a collection mechanism that is easy to disassemble is provided at the bottom of the separation bin, and a deceleration mechanism is provided on the side of the separation bin.

[0007] According to the above technical solution, the end of the long rod away from the rotating shaft is close to the inner wall of the separation bin, and half of the arc-shaped block is located in the slot in the initial state. When the arc-shaped block rotates clockwise, its straight surface cooperates with the slot to drive the separation bin to rotate.

[0008] According to the above technical solution, the depth of the groove is twice the length of the arc-shaped block, and the arc surface of the arc-shaped block faces counterclockwise. When the arc-shaped block rotates counterclockwise, its arc surface will be squeezed and completely retracted into the groove without driving the separation bin to rotate.

[0009] According to the above technical scheme, the conveniently disassembled collection mechanism includes a collection tank, an air pressure chamber and a partition, the bottom of the collection tank is penetrated by and fixedly connected with a tank mouth, the bottom of the tank mouth is provided with a sealing cover, the top of the tank mouth is penetrated by and fixedly connected with an insertion part, the side of the insertion part is provided with a square groove, the interior of the square groove is provided with a compression spring, the interior of the square groove is slidably connected with an arc block through the compression spring, the air pressure chamber is penetrated by and fixedly connected to the side of the separation chamber, one end of the air pressure chamber is provided with an air bag, the other end of the air pressure chamber is slidably connected with a piston rod, the end of the piston rod away from the air pressure chamber is fixedly connected with a pressure plate, the partition is fixedly connected to the interior of the separation chamber, and the interior of the insertion part is provided with an automatic sealing component.

[0010] According to the above technical solution, one-half of the arc block is located outside the square groove in the initial state, and the bottom of the arc block is in conflict with the inner bottom of the separation bin in the initial state. The conflict between the bottom of the arc block and the inner bottom of the separation bin makes it impossible for the insertion part to be separated from the separation bin.

[0011] According to the above technical solution, the airbag is in an expanded state in the initial state, and the width of the pressure plate is larger than the opening size of the square groove. When the airbag is squeezed, the air pressure inside it will enter the air pressure chamber to push the piston rod to move outside the air pressure chamber. When the pressure plate moves toward the square groove, it will squeeze the arc block to shrink it into the square groove, and the pressure plate will not enter the square groove.

[0012] According to the above technical solution, the automatic sealing component includes an opening block and a pressure rod, a groove body is opened at the bottom of the opening block, a sliding rod is fixedly connected to the inside of the groove body, a sealing plate is slidably connected to the surface of the sliding rod, an elastic spring is fixedly connected to the top of the sealing plate, one end of the elastic spring away from the sealing plate is fixedly connected to the top of the groove body, and the pressure rod is fixedly connected to the top of the partition.

[0013] According to the above technical solution, the end of the pressure rod away from the partition initially contacts the top of the sealing plate, and the elastic spring is in a stretched state in the initial state. When the pressure rod leaves the top of the sealing plate, the elastic spring rebounds and drives the sealing plate to move upward.

[0014] According to the above technical solution, the deceleration mechanism includes a connecting frame, which is fixedly connected to the side of the separation bin, and a reduction wheel is rotatably connected to the inner side of the connecting frame. An open groove is provided on the surface of the reduction wheel, and a tension spring is arranged inside the open groove. A resistance block is slidably connected to the inside of the open groove through the tension spring.

[0015] According to the above technical solution, the end of the reduction wheel away from the connecting frame is in close contact with the collecting tank in the initial state, and the material of the resistance block is rubber. When the collecting tank moves downward, it will rub against the reduction wheel to drive the reduction wheel to rotate. When the rubber resistance block contacts the collecting tank, it will generate greater resistance.

[0016] The present invention provides a microorganism separation device for clinical microbiological testing, which has the following beneficial effects:

[0017] (1) The present invention sets a stirrable separation mechanism so that the microbial sample and sterile water are put into the lower hopper through the feed pipe, and then enter the centrifugal bin through the lower hopper. When the motor is turned on to drive the rotating shaft to rotate counterclockwise, the rotating shaft drives the stirring head to stir the microbial sample and sterile water in the centrifugal bin to make them fully mixed. The centrifugal bin remains in place. When the motor is turned on to drive the rotating shaft to rotate clockwise, the centrifugal bin is driven to rotate synchronously. The centrifugal bin is separated into the separation bin by the centrifugal force generated by the rapid rotation of the centrifugal bin in cooperation with the connecting pipe and the filter screen therein, thereby completing the separation work. The stirring time is controllable, and the overall use is more convenient.

[0018] (2) The present invention facilitates the disassembly of the collection mechanism, so that the collection tank can be connected to the separation chamber through the cooperation of the insertion part, the arc block, the compression spring and other components. At this time, the microorganisms separated by centrifugation can flow into the collection tank through the separation chamber for collection. When the collected finished products need to be taken out, the air bags on both sides of the separation chamber are pressed. At this time, the pressure plate will squeeze the arc block back into the square groove, the insertion part is separated from the separation chamber, and the collection tank falls due to gravity, so that the collection tank can be removed. At the same time, the insertion part will be sealed with the cooperation of the automatic sealing component to prevent leakage of microorganisms.

[0019] (3) The present invention separates the insertion part from the separation bin by setting a deceleration mechanism. When the collection tank falls due to gravity, the speed of the collection tank falling due to gravity is slowed down by the cooperation of components such as the connecting frame, the deceleration wheel, the tension spring, and the resistance block, thereby preventing the collection tank from falling too fast and slipping from the operator's hands and falling directly to the bottom of the bin body and being damaged.

One end of the long rod 67 away from the rotating shaft 612 is close to the inner wall of the separation bin 65. In the initial state, one-half of the arc-shaped clamping block 610 is located in the clamping groove 66. When the arc-shaped clamping block 610 rotates clockwise, its straight surface cooperates with the clamping groove 66 to drive the separation bin 65 to rotate. The depth of the groove 68 is twice the length of the arc-shaped clamping block 610. The arc surface of the arc-shaped clamping block 610 faces counterclockwise. When the arc-shaped clamping block 610 rotates counterclockwise, its arc surface is squeezed and completely retracted into the groove 68, which will not drive the separation bin 65 to rotate. A convenient disassembly collection mechanism 7 is arranged at the bottom of the separation bin 65, and a deceleration mechanism 8 is arranged on the side of the separation bin 65.

[0032] During use, the microbial sample and sterile water are put into the bin body 1 through the feed pipe 4. At this time, the microbial sample and sterile water will enter the centrifugal bin 62 through the lower hopper 5.

[0033] See also Figure 1-9On the basis of the above embodiment, in another embodiment of the present invention, the convenient disassembly collection mechanism 7 includes a collection tank 71, an air pressure chamber 77 and a partition 711. The bottom of the collection tank 71 is penetrated and fixedly connected with a tank mouth 72. The bottom of the tank mouth 72 is provided with a sealing cover 712. The top of the tank mouth 72 is penetrated and fixedly connected with an insertion portion 73. A square groove 74 is opened on the side of the insertion portion 73. A compression spring 75 is provided inside the square groove 74. An arc block 76 is slidably connected to the inside of the square groove 74 through the compression spring 75. In the initial state, one-half of the arc block 76 is located outside the square groove 74, and the bottom of the arc block 76 is in conflict with the inner bottom of the separation chamber 65 in the initial state. The bottom of the part 72 is in conflict with the insertion part 73 so that the insertion part 73 cannot be separated from the separation chamber 65. The air pressure chamber 77 passes through and is fixedly connected to the side of the separation chamber 65. One end of the air pressure chamber 77 is provided with an air bag 78. The other end of the air pressure chamber 77 is slidably connected to a piston rod 79 inside the piston. The end of the piston rod 79 away from the air pressure chamber 77 is fixedly connected to a pressure plate 710. The air bag 78 is in an expanded state in the initial state. The width of the pressure plate 710 is larger than the opening size of the square groove 74. When the air bag 78 is squeezed, the air pressure inside the air bag 78 will enter the air pressure chamber 77 to push the piston rod 79 to move out of the air pressure chamber 77. When the pressure plate 710 moves in the direction of the square groove 74, it will squeeze the arc block 76 to shrink it into the square groove 74, and the pressure plate 710 will not enter the square groove 74. The partition 711 The automatic sealing component 9 is fixedly connected to the interior of the separation bin 65, and the interior of the insertion part 73 is provided with an automatic sealing component 9, which includes an opening block 91 and a pressure rod 96. A groove body 92 is provided at the bottom of the opening block 91, and a sliding rod 93 is fixedly connected to the interior of the groove body 92. A sealing plate 95 is slidably connected to the surface of the sliding rod 93. An elastic spring 94 is fixedly connected to the top of the sealing plate 95. One end of the elastic spring 94 away from the sealing plate 95 is fixedly connected to the top of the groove body 92. The pressure rod 96 is fixedly connected to the top of the partition 711. The end of the pressure rod 96 away from the partition 711 is in conflict with the top of the sealing plate 95 in the initial state, and the elastic spring 94 is in a stretched state in the initial state. When the pressure rod 96 leaves the top of the sealing plate 95, The elastic spring 94 will rebound and drive the sealing plate 95 to move upward. The deceleration mechanism 8 includes a connecting frame 81, which is fixedly connected to the side of the separation chamber 65. The inner side of the connecting frame 81 is rotatably connected to the reduction wheel 82. The surface of the reduction wheel 82 is provided with an open groove 83, and a tension spring 84 is arranged inside the opening groove 83. The inside of the opening groove 83 is slidably connected with a resistance block 85 through the tension spring 84. The end of the reduction wheel 82 away from the connecting frame 81 is in close contact with the collecting tank 71 in the initial state. The material of the resistance block 85 is rubber. When the collecting tank 71 moves downward, it will rub against the reduction wheel 82, thereby driving the reduction wheel 82 to rotate. The rubber resistance block 85 will generate greater resistance when in contact with the collecting tank 71.

[0034] When the locking cam 75 is in the unlocked position, the locking cam 73 is in the unlocked position, and the locking cam 73 is in the unlocked position, so that the locking cam 73 can be unlocked easily. The microbial solution passes through the filter screen 64 and enters the separation chamber 65. After separation, it will flow into the collection tank 71 through the insertion portion 73 for collection. The partition 711 can ensure that the microbial solution is all located above the insertion portion 73. When the collection tank 71 needs to be removed, the air bags 78 on both sides of the separation chamber 65 are pressed. The air pressure in the air bags 78 is squeezed and enters the air pressure chamber 77 to push the piston rod 79 to move out of the air pressure chamber 77. The movement of the piston rod 79 out of the air pressure chamber 77 will drive the pressure plate 710 to move in the direction of the square groove 74. When the pressure plate 710 moves in the direction of the square groove 74, The arc block 76 is squeezed to retract into the square groove 74, and the pressure plate 710 does not enter the square groove 74. When the arc block 76 is retracted into the square groove 74, the insertion portion 73 will be separated from the separation chamber 65, and the collection tank 71 will fall due to gravity, so that the collection tank 71 is removed, and when the insertion portion 73 is separated from the separation chamber 65, the pressure rod 96 will leave the top of the sealing plate 95. At this time, the elastic spring 94 will rebound and drive the sealing plate 95 to move upward and embed into the groove body 92, so that the insertion portion 73 is sealed to prevent leakage of the microbial solution. The installation and disassembly are simple and the efficiency is high. When 71 falls due to gravity, the collection tank 71 will rub against the reduction wheel 82 when moving downward, thereby driving the reduction wheel 82 to rotate. The faster the collection tank 71 falls, the faster the reduction wheel 82 rotates. The centrifugal force generated by the rapid rotation of the reduction wheel 82 will throw the resistance block 85 out of the opening groove 83. At this time, the rubber resistance block 85 will generate greater resistance when in contact with the collection tank 71, thereby slowing down the speed of the collection tank 71 falling due to gravity, preventing the collection tank 71 from falling too fast and slipping from the operator's hands and directly falling to the bottom of the warehouse body 1 and being damaged.
