DETAILED DESCRIPTION

[0026] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The preferred embodiments of the present application will be described in detail with reference to the drawings.

[0027] The present application discloses an intestinal flora sample pushing and sorting device, as shown in Figure 1 and Figure 2 , comprising:

[0028] The collecting unit comprises an extrusion cylinder 1 and a filtering assembly 2 arranged in the extrusion cylinder 1.

[0029] The sorting unit comprises a linear push rod 3 arranged outside the extrusion cylinder 1 and a pushing assembly 4 arranged in the extrusion cylinder 1. The output end of the linear push rod 3 is connected with the pushing assembly 4, and the linear push rod 3 drives the pushing assembly 4 to extrude the intestinal flora sample arranged in the filtering assembly 2.

[0030] Through the implementation of the intestinal flora sample pushing and sorting device, the filtering assembly 2 in the extrusion cylinder 1 is used to accommodate the intestinal flora sample and perform multi-stage filtering, and the linear push rod 3 drives the pushing assembly 4 to extrude the intestinal flora sample in the filtering assembly 2 in a linear stroke, so as to quickly extrude the intestinal flora sample in the filtering assembly 2, thereby fully extruding and dispersing the large impurities such as undigested food residues in the intestinal flora sample, and through the use of multi-stage filtering, the intestinal flora liquid can be efficiently extracted, and impurities are avoided from being mixed into the filtered intestinal flora liquid, thereby effectively ensuring the quality of the extracted intestinal flora liquid. Preferably, the linear push rod 3 is a driving source for linear stroke of a push rod linear motor, an electric push rod or the like.

[0031] Further, the filtering assembly 2 comprises a filtering container 21 and a filter screen 22. One end surface of the filtering container 21 is provided with an opening, and the pushing assembly 4 extrudes the intestinal flora sample arranged along the opening of the filtering container 21. The filter screen 22 is arranged in the filtering container 21, and the filter screen 22 is provided with multiple layers, and each layer of the filter screen 22 has different mesh sizes.

[0032] Through the implementation of the intestinal flora sample pushing and sorting device, the opening on one end surface of the filtering container 21 is used to cooperate with the pushing assembly 4, so that the pushing assembly 4 can reciprocatingly linearly move along the opening of the filtering container 21, thereby realizing the quick extrusion of the intestinal flora sample arranged in the filtering container 21. At the same time, the filter screen 22 with multiple layers and different mesh sizes can more finely filter the intestinal flora sample to remove particles and impurities of different sizes, so that the filtered intestinal flora liquid is more pure.

[0033] Further, the pushing assembly 4 comprises a pushing disc 41 and a pushing rod 42. The pushing disc 41 is slidingly arranged in the filtering container 21 along the opening of the filtering container 21, and the space between the pushing disc 41 and the filter screen 22 constitutes a sample accommodating chamber. One end of the pushing rod 42 is connected with the pushing disc 41, and the other end of the pushing rod 42 penetrates out of the extrusion cylinder 1 and is connected with the output end of the linear push rod 3.

[0034] The intestinal flora sample push sorting device is implemented as follows: the push disc 41 is arranged to slide in the filter container 21, and the intestinal flora sample is extruded by the intestinal flora sample driven by the linear push rod 3, so that the sorting process of the intestinal flora sample is realized. The push disc 41 is matched with the opening of the filter container 21, so that the push disc 41 slides in the filter container 21 while sealing the opening of the filter container 21. Therefore, the intestinal flora sample is placed in the sample containing cavity between the push disc 41 and the filter screen 22, so that the sample and impurities are limited in the sample containing cavity during the sorting process, and the leakage and pollution of the intestinal flora sample are effectively reduced. Meanwhile, the push disc 41 has a larger contact area with the intestinal flora sample, so that more uniform extrusion is realized, and the filtering efficiency and effect are improved. The stroke of the linear push rod 3 is controlled, so that the extrusion degree is accurately controlled, and the filtering requirements of different samples are met. For example, the first extrusion is stopped at 80% of the stroke for 1 minute, the second extrusion is stopped at 85% of the total stroke for 1 minute, the third extrusion is stopped at 80% of the total stroke for 30 seconds, and the last extrusion is stopped at the bottom for 3 minutes.

[0035] Further, the extrusion cylinder 1 is provided with an assembly hole corresponding to the push rod 42, and the assembly hole is provided with a leak-proof rubber ring 5 matched with the push rod 42.

[0036] Through the implementation of the intestinal flora sample push sorting device, the push rod 42 is driven by the linear push rod 3 to perform reciprocating linear motion on the extrusion cylinder 1. The leak-proof rubber ring 5 is arranged to increase the sealing performance between the push rod 42 and the assembly hole, effectively prevent the intestinal flora sample or other fluids from leaking between the push rod 42 and the assembly hole, and improve the sealing performance and reliability of the system. Meanwhile, the leak-proof rubber ring 5 can reduce the direct contact between the push rod 42 and the assembly hole, reduce wear and friction, and prolong the service life of the push rod 42 and the extrusion cylinder 1.

[0037] Further, one end surface of the extrusion cylinder 1 is provided with an opening, and a cylinder cover 11 is detachably connected to the opening of the extrusion cylinder 1. The assembly hole is arranged on the cylinder cover 11.

[0038] Through the implementation of the intestinal flora sample push sorting device, the cylinder cover 11 is detachably connected, so that the extrusion cylinder 1 can be easily opened for maintenance and replacement of internal components such as the push rod 42, the leak-proof rubber ring 5 or the filter screen 22, thereby reducing the difficulty and cost of equipment maintenance. The detachable cylinder cover 11 can be easily cleaned and inspected, ensuring the safety of operation and reducing the risk of accidents.

[0039] Further, the extrusion cylinder 1 is provided with a shunt sieve barrel 6. The filter assembly 2 is arranged in the shunt barrel, and a plurality of shunt holes are arranged on the outer wall of the shunt barrel in the circumferential direction.

[0040] Through the implementation of the above intestinal flora sample pushing and sorting device, by arranging the shunt sieve barrel 6, the intestinal flora liquid filtered by the intestinal flora sample through the multiple layers of filter screens 22 is first collected in the shunt sieve barrel 6, and then flows into the extrusion cylinder 1 after being shunted through the shunt holes on the shunt sieve barrel 6, so that the intestinal flora liquid flowing into the extrusion cylinder 1 is more evenly distributed, and small impurities in the intestinal flora liquid can be further filtered out, effectively reducing the risk of accumulation of particulate matter in the intestinal flora liquid in the extrusion cylinder 1, reducing the risk of blockage, thereby prolonging the service life of the intestinal flora sample pushing and sorting device.

[0041] Further, the intestinal flora sample pushing and sorting device further comprises an operation box 7, and the collecting unit and the sorting unit are arranged in the operation box 7. The extrusion cylinder 1 is arranged obliquely, and the outer wall of the extrusion cylinder 1 downwardly is provided with a discharge port 12 communicating with the inside of the extrusion cylinder 1. A plurality of collecting pipes 8 are arranged below the discharge port 12 in the operation box 7, and the plurality of collecting pipes 8 are in butt joint with the discharge port 12.

[0042] Through the implementation of the above intestinal flora sample pushing and sorting device, the collecting unit and the sorting unit are arranged in the operation box 7 to realize the integration of the intestinal flora sample pushing and sorting device, facilitate operation and use, and isolate the intestinal flora sample pushing and sorting device from the external environment to ensure that the intestinal flora sample pushing and sorting device operates under suitable environmental conditions. At the same time, the extrusion cylinder 1 is arranged obliquely, and the discharge port 12 is in butt joint with the collecting pipe 8, so that the filtered intestinal flora liquid can be smoothly collected at the discharge port 12 and discharged from the extrusion cylinder 1 to realize rapid collection of the intestinal flora liquid and ensure the stability of the device. In addition, the plurality of collecting pipes 8 can simultaneously collect the intestinal flora liquid discharged from the discharge port 12 to realize uniform collection.

[0043] Further, the outer wall of the extrusion cylinder 1 is provided with an air inlet 13 communicating with the inside of the extrusion cylinder 1, and the air inlet 13 and the discharge port 12 form an air exchange channel.

[0044] Through the implementation of the above intestinal flora sample pushing and sorting device, by using the air exchange channel formed by the air inlet 13 and the discharge port 12, inert gas can be introduced through the air inlet 13 to replace the oxygen in the extrusion cylinder 1 before the intestinal flora sample is sorted, so that the replaced oxygen is discharged from the discharge port 12 to ensure that the extrusion cylinder 1 is in an anaerobic environment, thereby inhibiting the growth and metabolism of some aerobic microorganisms by providing an anaerobic condition, reducing their interference with the flora liquid, and realizing more efficient extraction of the intestinal flora liquid.

[0045] Further, the support seat 71 is arranged in the operation box 7. The top surface of the support seat 71 is inclined, and the straight push rod 3 is arranged on the support seat 71. The support side plate 72 is arranged on the support seat 71, and the clamping hole 73 corresponding to the extrusion cylinder 1 is arranged on the support side plate 72. A plurality of support rods 74 parallel to the top surface of the support seat 71 are arranged on the support side plate 72, and the two ends of the support rod 74 are connected to the operation box 7.

[0046] Through the implementation of the above-mentioned intestinal flora sample pushing and sorting device, the top surface of the support seat 71 is inclined, and the extrusion cylinder 1 is assembled through the clamping hole 73 on the support side plate 72, so that the assembled extrusion cylinder 1 is in an inclined posture, so that the filtered intestinal flora liquid can be collected at the discharge port 12 along the inclined extrusion cylinder 1. At the same time, the support effect of the support side plate 72 is improved by the arrangement of the support rod 74, so as to improve the stability of the intestinal flora sample pushing and sorting device during operation.

[0047] Further, one side of the operation box 7 is provided with an opening, and the opening of the operation box 7 is provided with a detachably connected box door 75. The control panel 76 and the visual window 77 corresponding to the position of the extrusion cylinder 1 are arranged on the outer wall of the box door 75, and the control panel 76 and the straight push rod 3 are electrically connected.

[0048] Through the implementation of the above-mentioned intestinal flora sample pushing and sorting device, the detachably connected box door 75 at the opening of the operation box 7 enables the operator to conveniently open the operation box 7 for maintenance and replacement of internal components, such as the pushing rod 42, the leak-proof rubber ring 5 or the filter screen 22. And using the control panel 76 on the outer wall of the box door 75, the operator can conveniently set the parameters of the straight push rod 3, operate the control and monitor the running state of the equipment, so as to realize automatic control. The visual window 77 is a transparent window, and the arrangement of the visual window 77 enables the operator to directly observe the sorting and filtering of the intestinal flora sample without opening the operation box 7, which is convenient for real-time monitoring and adjustment.

[0049] The intestinal flora sample pushing and sorting device provided by the embodiment of the utility model realizes rapid extrusion of the intestinal flora sample by arranging the sample containing cavity between the pushing disc 41 and the filter screen 22 in the filter container 21 and driving the pushing disc 41 to slide in the filter container 21 by the straight push rod 3 until the intestinal flora sample in the filter container 21 is extruded, which helps to fully extrude and scatter the undigested food residues and other large impurities in the intestinal flora sample, and realizes multi-stage filtration of the intestinal flora sample by arranging the multi-layer filter screen 22 in the filter container 21, and realizes efficient extraction of the intestinal flora liquid by arranging the shunt sieve barrel 6 in the filter container 21 in the extrusion cylinder 1, and ensures the quality of the extracted intestinal flora liquid.
