In the following, each embodiment of the creation will be described in detail, and the drawings will be used as examples. In the description of the specification, in order to make the reader have a more complete understanding of this creation, many specific details are provided; however, this creation may still be implemented on the premise that some or all of the specific details are omitted. The same or similar elements in the drawings will be represented by the same or similar symbols. It is important to note that the drawings are for illustrative purposes only, and do not represent the actual size or number of components. Some details may not be fully drawn for simplicity.

Please refer to FIG. 1, a fat collection system according to an embodiment of the present invention includes a barrel 1 and a screen basket 2, wherein the screen basket 2 is set in the barrel 1. In some embodiments, the barrel 1 and the screen basket 2 Can be integrated. The barrel 1 includes a feeding port 10, an exhaust port 11, a bottom drainage port 12 and an accommodating space 13, wherein the accommodating space 13 is surrounded by a top 14, a side wall 15 and a bottom 16 to accommodate the space 13 communicates with the feeding port 10, the exhaust port 11 and the bottom drain port 12, and the two side ends of the side wall 15 are connected to the top 14 and the bottom 16 respectively.

In this embodiment, the inlet 10 faces the screen basket 2 and is arranged on the top 14 of the cylinder 1. For example, the inlet 10 is opened in the center of the top 14, but not limited to this. The cylinder 1 receives the mixture A through the feed port 10 and flows into the screen basket 2. The screened mixture A will flow into and be stored in the containing space 13, for example, the screen basket 2 is arranged in the containing space 13 and covers Below the inlet 10, and the sieve basket 2 sieves the mixture A to discharge the sieved mixture A to the accommodating space 13, wherein the mixture A includes water A1 and a small volume of fat A2. In some embodiments, the side and bottom of the screen basket 2 are provided with a plurality of screen holes 20. In at least one embodiment, the size of the plurality of mesh holes 20 ranges from 1 mm to 4 mm, but not limited thereto.

Since the sifted water A1 and fat A2 have different hydrophilicity and density values, when the sifted mixture A is stored in the storage space 13, it will be automatically separated into two layers of fluid by gravity under the action of gravity Intersect at an interface A12. As a result, the sifted water A1 and fat A2 form a layered structure separated from each other and are stored in the storage space 13.

In order to guide the mixture A to smoothly flow into the cylinder 1, an exhaust port 11 is opened at the top 14 of the cylinder 1 for exhausting gas such as air in the accommodating space 13, for example, the exhaust port 11 is opened at The peripheral portion of the top 14 deviates from the center, that is, the orthographic projection of the exhaust port 11 on the top 14 does not overlap the orthographic projection of the screen basket 2 on the top, so that the exhaust port 11 and the screen basket 2 are misaligned with each other It is configured to prevent fat or water in the screen basket 2 from being discharged out of the cylinder 1 through the exhaust port 11, and ensure that only the gas in the accommodating space 13 will be discharged out of the cylinder 1 through the exhaust port 10. Thereby, after the at least part of the gas is discharged from the accommodating space 13 of the cylinder 1, a negative pressure state is formed, so that the mixture A can smoothly flow into the cylinder 1. In some embodiments, in order to speed up the flow rate of the mixture A in the barrel 1, the fat collection system can be optionally equipped with a vacuum pump, which is connected to the exhaust port 11 of the barrel 1 through a negative pressure pipe to draw the discharge volume Gas in the space 13, but not limited to this.

In addition, the bottom drain 12 is provided at the bottom 16, for example, the bottom drain 12 is opened at the central portion of the bottom 16, but it is not limited thereto. Since the fat A2 in the accommodating space 13 is suspended in the upper layer and away from the bottom 16, the barrel 1 can drain the water A1 adjacent to the bottom 16 out of the barrel 1 through the bottom drain 12. In this way, the sieved fat A2 will remain in the accommodating space 13 of the barrel 1 for subsequent transplantation.

One of the factors for the success of fat transplantation is the quality and survival rate of the collected fat cells. For example: after the transplantation of an excessively large fat mass, the fat cells in the center of the mass cannot easily absorb nutrients and the survival rate is low; or The autologous tissue removed by liposuction is often accompanied by components other than fat cells, such as fibrous tissue, not the fat cells required for the transplantation destination. Therefore, according to the above structure, the present disclosure discloses that the gravity separation mechanism and the screening mechanism through the barrel 1 and the screen basket 2 can effectively improve the quality and survival rate of the fat A2 collected, and is suitable for separating and collecting high survival from living tissue The rate of fat cells needed for fat transplantation surgery has many functions and advantages as mentioned above.

The fat collection system according to another embodiment of this creation is described below. Please refer to FIG. 2. In this embodiment, in order to prevent the fat A2 to be collected from being discharged out of the barrel 1 and thereby improve the quality and quantity of fat A2, the fat collection system is further equipped with a filter screen 5. The filter screen 5 is arranged on the bottom 16 of the cylinder 1 and covers the bottom drain 12. The filter 5 filters out the water A1 to be discharged to the bottom drain 12, so that the fat A2 remains in the accommodating space 13. In at least one embodiment, the size of the plurality of filter holes of the filter screen 5 is between 100 um and 400 um, which can smoothly discharge the water A1, while ensuring that the fat A2 larger than the filter hole size is retained in the accommodating space 13, Thereby effectively increasing the amount of fat A2 collected. In some embodiments, the geometric shape of the filter screen 5 may be a plate shape, a cone shape or a circular arc shape, but it is not limited thereto.

The difference between the fat collection system of this embodiment and that illustrated in FIG. 1 is the improvement and optimization of the drainage path. Specifically, the water A1 in FIG. 1 flows into the accommodating space 13 of the cylinder 1 through the inlet 10 and is discharged out of the cylinder 1 through the bottom drain 12, that is, the cylinder 1 has the inlet 10 , A single drainage path composed of the accommodating space 13 and the bottom drainage port 12. However, the fat collection system illustrated in FIG. 2 is provided with a side drain path composed of the feed inlet 10, the accommodating space 13 and the side drain 17 and a feed outlet 10, the accommodating space 13 and the bottom drain 12 The bottom drainage path formed is described in detail below.
