Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a simple negative pressure fat-water separation device. Background Art

[0002] Fat is a very good natural filler. It can also promote metabolism and cell renewal in the filled area, solving the problem of skin rejuvenation to a certain extent. Therefore, fat is also known as "soft gold". After the body's excess fat is sucked out of the body, it is processed in a special way and finally the purified fat is filled back into the relatively missing areas to achieve the patient's pursuit of improved appearance. Before autologous fat is used for backfilling, the fat needs to be separated and purified before it can be used for autologous fat breast augmentation, autologous fat buttocks augmentation, etc.

[0003] However, the fat separation methods currently available on the market use static filtration through filters, which has a low separation efficiency and causes the fat to be exposed to the air for too long, which makes it easy for it to be contaminated. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a simple negative pressure fat-water separation device, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a simple negative pressure suction fat-water separation device, comprising a separation tank and a separation mechanism, characterized in that the separation mechanism comprises: a filter cartridge, a cotton pad, and gauze, a filter cartridge convex edge is installed on the upper end of the filter cartridge, a binding groove is opened on the outer side of the filter cartridge convex edge, a rubber gasket is arranged above the gauze, and an upper cover plate is arranged above the separation tank.

[0006] As a further solution of the utility model: a sleeve is installed on the upper cover plate, a crank is arranged inside the sleeve, a stirring rod is installed on the outer side of the lower end of the crank, and a bearing is installed on the outer side of the crank inside the sleeve.

[0007] As a further solution of the utility model: a negative pressure pipe is arranged on the outer side of the lower end of the separation tank, and an engaging thread is opened on the outer side of the upper end of the separation tank.

[0008] As a further solution of the utility model: the outer side array of the filter cartridge is provided with filter through holes.

[0009] As a further solution of the utility model: the upper cover plate and the separation tank are engaged and fixed by the engaging threads, and the negative pressure pipe is arranged through the separation tank.

[0010] As a further solution of the utility model: the crank is movably arranged through the bearing and the sleeve.

[0011] As a further solution of the utility model: a clamping gasket ring for support is installed on the inner side wall of the separation tank below the filter cartridge.

[0012] As a further solution of the utility model: the rubber gasket is snap-connected with the binding groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The upper cover plate is integrally covered on the top of the separation tank to reduce the contact time between fat and air. The stirring rod at the lower end of the crank is controlled to stir the fat inside as a whole. The fat, saline, anesthetic drugs, etc. in the fat particles are fully absorbed by the cotton pad by repeatedly turning and stirring, thereby ensuring the separation efficiency and increasing the separation speed with the effect of negative pressure.

[0015] The negative pressure can absorb the oil and fat inside the cotton pad into the separation tank as a whole, thus avoiding the cotton pad from being saturated. The negative pressure can also accelerate the rapid separation of the liquid inside the fat. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, the present embodiment provides a simple negative pressure suction fat-water separation device, comprising a separation tank 1, characterized in that a separation mechanism 7 is arranged inside the separation tank 1, and the separation mechanism 7 comprises: a filter cartridge 701, a cotton pad 704, and a gauze 705. The cotton pad 704 and the gauze 705 are all made of disposable sterilized materials. A filter through hole is arranged in an array on the outer side of the filter cartridge 701, a filter cartridge flange 702 is installed on the upper end of the filter cartridge 701, a clamping gasket ring 101 for support is installed on the inner side wall of the separation tank 1 below the filter cartridge 701, a binding groove 703 is arranged on the outer side of the filter cartridge flange 702, a rubber gasket 706 is arranged above the gauze 705, and the rubber gasket 706 is limited by binding the gauze 705 as a whole to the inside of the binding groove 703, and an upper cover plate 2 is arranged above the separation tank 1.

[0024] like Figure 2-5 As shown, in this embodiment, a sleeve 4 is installed on the upper cover plate 2, a crank 3 is arranged inside the sleeve 4, and the crank 3 is movably arranged with the sleeve 4 through a bearing 301, a stirring rod 302 is installed on the outer side of the lower end of the crank 3, and a bearing 301 is installed inside the sleeve 4 on the outer side of the crank 3, a negative pressure pipe 6 is arranged on the outer side of the lower end of the separation tank 1, and the negative pressure pipe 6 is arranged through the separation tank 1, and an engaging thread 5 is opened on the outer side of the upper end of the separation tank 1, and the upper cover plate 2 is engaged and fixed with the separation tank 1 through the engaging thread 5.

[0025] The working principle of the utility model is as follows: before the liposuction operation is performed, the cotton pad 704 is rolled up as a whole into a circular ring with the same inner diameter as the filter cartridge 701 and then placed on the inner wall of the filter cartridge 701, and then the gauze 705 is flatly laid and fitted on the inner side of the cotton pad 704, and the excess part of the gauze 705 is covered on the outer side of the filter cartridge convex edge 702 at the upper end of the filter cartridge 701, and the rubber gasket 706 is bound as a whole to the inside of the binding groove 703 to achieve the limiting fixation of the gauze 705, and the filter cartridge 701 is placed as a whole inside the separation tank 1 and limited with 101, and the extracted fat is poured as a whole into the inside of the gauze 705, and the upper cover plate 2 is used to cover the filter cartridge as a whole. The top of the separation tank 1 is engaged and fixed with the engaging thread 5, and the torque is applied to the crank 3 to control the stirring rod 302 at the lower end of the crank 3 to stir the fat inside. The fat particles are repeatedly turned over and stirred so that the oil, saline, anesthetic drugs, etc. in the fat particles are fully absorbed by the cotton pad 704. The negative pressure tube 6 is connected to a negative pressure source externally, and the negative pressure is absorbed by the oil and other substances inside the cotton pad 704 toward the inside of the separation tank 1 to avoid saturation of the cotton pad 704. After the absorption is completed, the upper cover plate 2 is disassembled as a whole, and the fibrous tissue in the fat particles is picked out with tweezers (to prevent obstruction during backfilling). Finally, the purified fat is collected and transferred for standby use.
