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.
