The same or similar elements in the drawings will be represented by the same or similar symbols. It should be noted that the drawings are for illustrative purposes only, and do not represent the actual size or quantity of the components. Some details may not be completely drawn in order to keep the drawings concise.

Fig. 1 is a three-dimensional view of the fat screening device according to an embodiment of the creation, Fig. 2 is a three-dimensional exploded view of the fat screening device according to an embodiment of the creation, and Fig. 3 is a perspective view of the filter screen of the fat screening device in Fig. 2, wherein Fig. 2 is View the filter from the top-down perspective, and Figure 3 shows the filter from the bottom-up perspective. Please refer to Figures 1 to 3, the fat screening device of an embodiment of the present invention includes a cylinder 10 and a sieve basket 20, wherein the sieve basket 20 is assembled in the cylinder 10. In some embodiments, the cylinder 10 and the sieve The basket 20 can be integrally formed. The cylinder 10 includes a material inlet 11, an exhaust port 12, a bottom drain 13 and an accommodation space 14. The accommodation space 14 is surrounded by the top 15, side walls 16 and bottom 17 of the cylinder 10. The accommodation space 14 is connected to the inlet 11, the exhaust port 12, and the bottom drain port 13, and the two ends of the side wall 16 are connected to the top 15 and the bottom 17 respectively.

Figure 4 is a cross-sectional view of a fat screening device according to an embodiment of the invention. 1 to 4, in this embodiment, the inlet 11 faces the screen basket 20 and is arranged at the top 15 of the cylinder 10. For example, the inlet 11 is opened at the center of the top 15, but Not limited to this. The cylinder 10 receives the mixture A through the inlet 11 and flows into the sieve basket 20. The sieve-filtered mixture A will flow into and be stored in the accommodating space 14. For example, the sieve basket 20 is disposed in the accommodating space 14 and covers Below the inlet 11, the sieve basket 20 sieves the mixture A to discharge the sieved mixture A to the accommodating space 14. The mixture A includes water A1 and a small volume of fat A2. In some embodiments, the side and bottom of the screen basket 20 are provided with a plurality of screen holes 21. In at least one embodiment, the size range of the plurality of sieve holes 21 is between 1 mm and 4 mm, but it is not limited thereto.

Since the sieved water A1 and the fat A2 are different in hydrophilicity and density values, when the sieved mixture A is stored in the containing space 14, it will be automatically separated into two layers of fluid under the action of gravity. Intersect at an interface A12. Thereby, the filtered water A1 and fat A2 will form a layered structure separated from each other and be stored in the accommodating space 14.

In order to guide the mixture A to flow into the cylinder 10 smoothly, the top 15 of the cylinder 10 is provided with an exhaust port 12 for exhausting the gas in the accommodating space 14, such as air. For example, the exhaust port 12 is opened in The peripheral edge of the top 15 is deviated from the center, that is, the orthographic projection of the exhaust port 12 on the top 15 does not overlap with the orthographic projection of the screen basket 20 on the top 15 so that the exhaust port 12 and the screen basket 20 are mutually The dislocation configuration prevents the fat or water in the screen basket 20 from being discharged out of the cylinder 10 through the exhaust port 12 and ensures that only the gas in the containing space 14 will be discharged out of the cylinder 10 through the exhaust port 12. Thereby, the accommodating space 14 of the cylinder 10 will form a negative pressure state after at least part of the gas is discharged, so that the mixture A can flow into the cylinder 10 smoothly.

Figure 5 is another cross-sectional view of the fat screening device according to an embodiment of the invention. As shown in FIG. 5, in this embodiment, in order to accelerate the flow rate of the mixture A in the cylinder 10, the fat screening device 1 can be optionally equipped with a vacuum pump P1, which is connected to the exhaust port of the cylinder 10 through a negative pressure tube H 12. The gas in the accommodating space 14 is exhausted by suction, but not limited to this.

In addition, the bottom drain 13 is provided at the bottom 17 of the cylinder 10, for example, the bottom drain 13 is opened at the center of the bottom 17, but not limited to this. Since the fat A2 in the accommodating space 14 is suspended in the upper layer and away from the bottom 17, the cylinder 10 can drain the water A1 adjacent to the bottom 17 out of the cylinder 10 through the bottom drain 13. In this way, the filtered fat A2 will be retained in the accommodating space 14 of the cylinder 10 for subsequent transplantation.

Since one of the factors for the success of fat transplantation is the quality and survival rate of the collected fat cells, for example: after transplantation of a fat mass that is too large, the fat cells in the center of the mass will not easily absorb nutrients and thus have a low survival rate; or , The autologous tissue removed by liposuction is often accompanied by other components besides fat cells, such as fibrous tissue, rather than the fat cells required for the transplantation target site. Therefore, according to the above structure, the present disclosure effectively improves the quality and survival rate of the collected fat A2 through the gravity separation mechanism and the sieving mechanism of the cylinder 10 and the sieve basket 20, and is suitable for separating and collecting high-survival fat from living tissues. Fat cells at a higher rate for fat transplantation surgery have many functions and advantages as mentioned above.
