Description

Technical Field

[0001] This utility model belongs to the field of fat filtration technology, and in particular relates to a fat tissue separation filter. Background Technology

[0002] Adipose tissue is typically obtained through aspiration, and it contains various other components such as blood and bulking agents. Therefore, the extracted fat needs to be washed multiple times with saline or PBS in a syringe, a time-consuming and labor-intensive process. Furthermore, repeated washing can lead to fat loss and the loss of adipose-derived stem cells. Existing experimental filters are too small, filtering too little fat, and are also time-consuming and labor-intensive. Therefore, to address these problems, this technical solution proposes an adipose tissue separation filter. Utility Model Content

[0003] This invention provides a fat tissue separation filter, which includes a filter cartridge and a filter screen. The filter screen has multiple filtration holes to remove bulking agents, blood, and other substances from the fat tissue. The filter is simple, practical, and easy to operate, accelerating the experimental process and improving the convenience of human fat tissue separation experiments. It can accelerate the filtration of blood and bulking agents from the fat tissue, thus improving the convenience of fat tissue separation experiments. In summary, it solves the problems in the background technology.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model discloses a fat tissue separation filter, which includes a conical filter cylinder with open ends that are larger at the top and smaller at the bottom, and a filter screen fixedly installed on the inner wall of the conical filter cylinder.

[0006] Furthermore, the filter screen adopts a downwardly curved arc shape.

[0007] Furthermore, the conical filter cartridge is made of stainless steel with a wall thickness of 1mm. The inner wall diameter of the upper fat tissue inlet is 80mm, and the inner wall diameter of the lower filtrate outlet is 20mm.

[0008] Furthermore, the outer circumferential diameter of the upper surface of the filter screen is 30mm, and filter holes are uniformly opened on the surface of the filter screen, with a side length of 100mm for each filter hole.

[0009] The present invention has the following advantages over the prior art:

[0010] The filter has a conical design, making it easier to organize and administer.

[0011] The filter includes a filter cartridge and a filter screen. The filter screen has multiple filtration holes to remove bulking agents, blood, and other substances from adipose tissue. It has a simple, practical, and easy-to-operate structure, which speeds up the experimental process and improves the convenience of human adipose tissue separation experiments.

[0012] The stainless steel material design facilitates cleaning and reuse, greatly reducing experimental costs;

[0013] The filter screen has a larger pore diameter than ordinary cell sieves, which improves the efficiency of tissue separation and reduces cell loss. The filter is simple, practical and easy to operate, which speeds up the experimental process and improves the convenience of adipose tissue separation experiments. It can accelerate the filtration of blood and bulking agents from adipose tissue, further improving the convenience of adipose tissue separation experiments.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "bent", "arc", "upper end", "inner wall", "peripheral side", "surface", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Please see Figure 1-4 As shown, the present invention provides a fat tissue separation filter, comprising a conical filter cylinder 1 with both ends open, which is larger at the top and smaller at the bottom, and a filter screen 2 fixedly installed on the inner wall of the conical filter cylinder 1.

[0025] The filter screen 2 has a downward-curved arc shape. In this specific embodiment, the filter screen 2 is woven from stainless steel wire and welded to the inner wall of the conical filter cylinder 1 for fixation, thus ensuring a seal and preventing liquid from flowing out from the edge of the filter screen. The arc shape of the filter screen 2 facilitates the separation of adipose tissue from other liquid components by gravity, making it easy to collect the filtrate. The structure is simple, practical, and easy to operate. The filter cylinder uses a conical design with openings at both ends, allowing adipose tissue to be added from the top and the filtrate to be collected and filtered out from the bottom. In the adipose tissue separation filter, the filter holes are evenly distributed on the filter screen, which can easily separate adipose tissue and filtrate.

[0026] The conical filter cartridge 1 is made of stainless steel with a wall thickness of 1mm. The inner diameter of the upper adipose tissue inlet is 80mm, and the inner diameter of the lower filtrate outlet is 20mm. The lower filtrate outlet allows tissue fluid and blood to pass through, but adipose tissue cannot. The lower outlet 4 has a diameter of 20mm.

[0027] The outer circumference diameter of the upper surface of the filter screen 2 is 30mm, and the filter screen 2 is uniformly provided with filter holes 21, the side length of which is 100mm.

[0028] When adipose tissue is placed in the filter, impurities such as blood and swelling agents are removed through the filter screen. The filter pores allow liquid to flow down quickly while preventing adipose tissue from passing through, thus rapidly obtaining purified fat that can be used for subsequent transplantation or primary culture of adipose-derived stem cells. Using this adipose tissue filter accelerates the process, improves the convenience of separating adipose-derived stem cells from adipose tissue, and reduces liquid loss.

[0029] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
