[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. Therefore, the following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the present disclosure for which protection is claimed, but merely represents selected embodiments of the present disclosure.

[0021] In the description of the present disclosure, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0022] Example 1

[0023] Reference Figure 1 and 3 As shown, the embodiment of the present disclosure provides a microorganism sorting device, comprising: a filter bag 2 and a collection bag 1. The filter bag 2 is arranged in the collection bag 1.

[0024] The sorting is to separate the microorganisms from the substances to be separated to obtain purified microorganisms.

[0025] The upper part of the filter bag 2 is installed on the upper part of the collection bag 1. The filter bag 2 can be detachably or non-detachably connected to the collection bag 1 by gluing, sewing, etc.

[0026] Cooperative mechanisms, such as Velcro, may also be provided on both to facilitate the packaging and storage of the products, which can then be connected before use.

[0027] The detachable design of the filter bag 2 can reduce the difficulty of removing the microorganisms. After the filtration is completed, the filter bag 2 is removed to avoid the removal of the microorganisms from the collection bag 1 with the filter bag 2, and to avoid the situation where the filter bag 2 is contaminated with microorganisms due to operational errors.

[0028] The filter bag 2 can be a disposable product.

[0029] The collecting bag 1 comprises an easy-tear opening 11 and a first mounting portion 12 .

[0030] The easy-tear opening 11 is arranged at the lower part of the collecting bag 1 .

[0031] The tearable opening 11 includes a hand-tear portion extending from the bag body of the collection bag 1 and a set of tear lines arranged on the bag body. The tear lines are connected in parallel to the rear end of the hand-tear portion. The hand-tear portion is used to facilitate the user to hold and pull, so that the bag body is damaged along the tear line to form a gap. The gap is sufficient to pour out the liquid filtered by the filter bag 2 in the collection bag 1, and to remove the microorganisms sorted in the bag.

[0032] Further, see Figure 1 The collecting bag 1 is covered with a protective film on the entire tearable opening 11 or the part near the hand-tear portion, and the protective film is used to protect the hand-tear portion from being accidentally touched before use, which may cause the tearing line to rupture.

[0033] The first mounting portion 12 is disposed on the upper portion of the collection bag 1. Figure 1 The first mounting portion 12 is a ring-shaped structure.

[0034] The first mounting portion 12 is used to fix the device to prevent it from tipping over, causing the material in the device to flow out from the upper opening of the device.

[0035] After the device is placed in a container, the first mounting portion 12 is turned down and sleeved on the upper opening of the container, thereby providing support for the container to keep it in a positive placement state.

[0036] Furthermore, an elastic ring matched with the container is used to fix the first mounting portion 12 after being sleeved, so as to prevent the first mounting portion 12 from shifting and causing the device to lose support.

[0037] Alternatively, the first mounting portion 12 is made of an elastic material so as to provide sufficient elastic force to fix the device on the container.

[0038] Reference Figure 3 The filter bag 2 is a filter structure, which is used to filter the substances put therein, so as to sort out the microorganisms in the substances.

[0039] The substance needs to be fluid to achieve filtration, and can be dispersed by adding physiological saline.

[0040] Physiological saline can also be used as a carrier to make the microorganisms flow to the bottom of the collection bag 1 for easy collection. Physiological saline can also be added to the collection bag 1 after filtering to concentrate the microorganisms.

[0041] Furthermore, the substance is feces.

[0042] In some embodiments, the filter bag includes a first filter layer and a second filter layer, the first filter layer is arranged on the outside of the second filter layer, and the pore size of the first filter layer is smaller than the pore size of the second filter layer.

[0043] The second filter layer is used to first filter out larger impurity particles in the substance to be separated and retain them on the inner side of the second filter layer, while smaller impurity particles and microorganisms are filtered and reach the first filter layer.

[0044] The first filter layer is used to filter out smaller impurity particles and retain them on the inner side of the first filter layer, thereby separating the microorganisms and allowing them to enter the collection bag 1.

[0045] The double filtration method can avoid the situation where large particles in the substance to be separated clog the smaller filter holes when the first filter layer is directly used, thereby affecting the filtration efficiency.

[0046] Furthermore, the filter bag 2 can be designed to include more filter mesh layers, so as to achieve the separation of different impurity particles.

[0047] Furthermore, the pore size of the first filter layer is 90 to 120 microns, and the pore size of the second filter layer is 30 to 50 microns.

[0048] The diameter of bacteria is mostly between 0.2 and 1 micron, and the length may be between 0.5 and 5 microns. The above aperture setting can ensure the collection of bacteria.

[0049] The collection bag 1 is made of liquid-tight material and is used to collect and sort the microorganisms and their carriers, such as physiological saline.

[0050] In some embodiments, reference Figure 1 The caliber of the lower part of the collecting bag 1 is larger than the caliber of the upper part.

[0051] The smaller upper opening facilitates the fixing of the collecting bag 1 on the container and the force balance during the fixing.

[0052] The larger lower opening facilitates the removal of the microorganisms in the collection bag 1, and has a positive effect on the sorting effect and the reduction of microorganism loss, especially when a large number of samples need to be processed quickly.

[0053] The device has a wide range of applicability and can be adapted to a variety of containers, including centrifuge tank models used in a variety of centrifuges. Such a design ensures the versatility and flexibility of the device, making it easy to use in different experimental and production environments.

[0054] The method of using the device may be:

[0055] After limiting the position of the device to prevent it from tipping over, the substance to be separated is dispersed in physiological saline (if the substance to be separated has good fluidity, it can be directly put in), and placed in the filter bag 2 of the device, and filtered by standing, or the substance in the filter bag 2 is stirred regularly to prevent larger impurity particles from precipitating and blocking the microorganisms from passing through the filter holes.

[0056] Example 2

[0057] Reference Figure 1 , 4 As shown in Figure 5 , the embodiment of the present disclosure provides a centrifuge tank, comprising: a main body 3 , and the microorganism sorting device described in Example 1 . The lower part of the device is accommodated in the main body 3 .

[0058] In some embodiments, the main body 3 includes: a tank body 31 and a tank cover 32 , and the tank cover 32 is installed on the upper part of the tank body 31 .

[0059] The function of the can cover 32 is to prevent the material in the filter bag 2 of the device from spilling out from the opening of the main body 3 during the centrifugation process.

[0060] The first mounting portion 12 of the device is sleeved on the upper part of the tank body 31. The first mounting portion 12 is made of elastic material to provide a tight elastic force. Then, the tank cover 32 is sleeved on the outside of the first mounting portion 12.

[0061] In some embodiments, further, the upper portion of the tank body 31 has a concave-convex texture design at the installation location of the device, which can increase the strength of the first installation portion 12 being mounted on the tank body 31.

[0062] The centrifuge tank is placed in a suitable centrifuge for centrifugation, thereby achieving the sorting of the microorganisms in the microorganism sorting device.

[0063] In practical applications, the centrifuge tank can efficiently complete the separation and purification of microorganisms in the substance to be separated, for example, the separation and purification of intestinal microorganisms in feces. It has the characteristics of simple operation, cost-effectiveness, and strong practicality. It is particularly suitable for the rapid extraction and purification of microorganisms in laboratories and medical settings.

[0064] Example 3

[0065] Reference Figure 2 As shown, the embodiment of the present disclosure provides a microorganism sorting device, which is different from the device described in Example 1 in that: no first mounting portion 12 is provided. The upper part of the collection bag 1 is provided with one or more sets of relative connection mechanisms. Figure 2 The middle one is hook 13.

[0066] When the lower part of the device is accommodated in a container, the hook 13 can be used to hang on a corresponding mechanism above the container, such as a laboratory rack, so that the device can be kept in a positive placement state.

[0067] Example 4

[0068] The embodiment of the present disclosure provides a centrifugal tank, which is different from the centrifugal tank described in Example 2 in that the centrifugal tank is adapted to the microorganism sorting device described in Example 2. A hanging ring (not shown) that cooperates with the hook 13 is provided at the bottom of the tank cover 32 of the main body 3 to achieve the fixation of the device on the tank cover 32. Then the device is placed in the tank body 31, and the tank cover 32 is installed on the upper part of the tank body 31, for example, by threaded connection.

[0069] The centrifuge tank is placed in a suitable centrifuge for centrifugation, thereby achieving the sorting of the microorganisms in the microorganism sorting device.

[0070] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
