The effective filtered components of the device are as follows: 0.9% physiological saline, epinephrine (1 ml:1 mg), lidocaine hydrochloride (5 ml:0.1 g).
Further, the manual negative pressure has the following six characteristics: 1. the negative pressure can be automatically, timely and accurately adjusted; 2. the controllability is good, and a 50ml syringe 7 can be seen every 2ml (each cell) of suction; 3. almost no damage to fat particles; 4. the fat swelling liquid is filtered and separated quickly, so that the operation time is shortened greatly; 5. the in vitro time of fat is reduced, so that the survival rate of the fat is obviously improved; 6. the epinephrine and the lidocaine contained in the swelling liquid have adverse effects on the activity of fat, and the lidocaine and 1/500000 epinephrine can obviously inhibit the activity of fat particles, so that the survival rate of fat tissues can be improved by removing the two substances.
In the embodiment of the present application, after the separation of the filtrate and the adipocytes, the filtrate (swollen liquid) in the suction bottle 4 is discharged by unscrewing the screw head 3 and the screw hole 44, which is also applicable to more solution filtration, so that the filtration can be continuously performed, as shown in fig. 1 to 3. The second threaded connection port 42 can also be connected with the syringe 7, so that the negative pressure is increased, and the accommodating cavity 12 formed in the filter funnel 1 is used for pouring swelling liquid.
Further, the cover 6, the filter funnel 1 and the suction bottle 4 are all in a cylindrical structure, and the diameter of the filter funnel 1 is equal to that of the suction bottle 4; the capacity of the filter funnel 1 and the suction filter flask 4 is 100ml; the outer wall of the filter funnel 1 and the outer wall of the suction filter bottle 4 are provided with graduated scales 5; and the interval of each section of the graduated scale 5 is 10ml.

In this embodiment, a handle 61 is fixed to one side of the lid 6, and the lid 6 is removed from the filter funnel 1 by lifting the handle 61, so that the filter layer 11 is removed, and the adipocytes remaining on the surface of the filter layer are collected.
The utility model is used when in use: the screw thread head 3 is screwed into the screw hole 44, the screw hole 44 is sealed by the first seal ring 31, the metal plug 43 is in threaded connection with the second screw thread connection port 42, the two first screw thread connection ports 41 on the upper part of the outer wall of the suction filtration bottle 4 are in threaded connection with the 50ml syringe 7 with threads, the swollen liquid containing fat is poured into the accommodating cavity 12, then the cover 6 is covered on the accommodating cavity 12, the outlet of the swollen liquid is sealed, and the 50ml syringe 7 on one side starts to suck air, so that the air pressure in the suction filtration bottle 4 is reduced, the pressure difference is formed due to the action of atmospheric pressure and gravity, the swollen liquid on the funnel support 2 can rapidly flow into the suction filtration bottle 4 below through the microporous filtration layer 11, and the fat is remained on the microporous filtration layer 11 through the filtration holes 111, so that the purpose of filtration is achieved. If the syringe 7 cannot be drawn, it means that the filtering hole 111 is blocked by fat particles, the swelling liquid in the filtering funnel 1 is only required to be stirred by opening the cover 6, and the swelling liquid can be continuously separated by closing the cover 6 and then passing through the syringe 7. If the pressure needs to be increased again, the syringe 7 with the negative pressure can be fixed by a negative pressure pressurization booster, then the syringe 7 with the other 50ml is used for pumping, and the magnitude of the negative pressure can be controlled according to the amounts respectively observed in the swelling liquid in the filter funnel 1 and the suction filter flask 4. When the process is finished, the negative pressure is stopped and removed, so that the normal pressure in the suction filtration bottle 4 is recovered, and the suck-back is prevented.
