Description
Technical Field
The invention discloses a device for purifying and collecting autologous fat mixture and a purification method.
Background
The conventional fat transplantation operation includes three parts of fat acquisition, fat treatment and fat transplantation. The fat mixture obtained from the supply area contains fat droplets, moisture, red blood cells, platelets, white blood cells, various cell fragments, pharmaceutical ingredients and other various ineffective or even harmful ingredients besides fat cells and fat active ingredients.
The fat treatment is intended to improve the survival rate of fat transplantation by removing impurities to obtain high-purity fat cells and fat active ingredients. Conventional fat processing techniques include a standing method, a centrifugation method, and an adsorption method. Using the static method, it is possible to stratify the different components of the fat mixture according to their respective densities by means of gravity, which yields adipose tissue with high activity but insufficient lipid droplet and moisture removal capacity. The centrifugation method is used for layering components in the fat mixture by means of high-speed centrifugation, which can rapidly remove fat droplets and water in the fat mixture, but can cause damage to fat cells during centrifugation, so that the survival rate of fat transplantation is reduced. The adsorption method is to filter the fat mixture by using gauze, cotton pad and other materials, wherein the water and oil drops in the fat mixture are adsorbed by the gauze or cotton pad, and the fat tissue is retained on the surface of the gauze or cotton pad. The method can remove impurity components mixed in fat cells as far as possible under the condition of ensuring the activity of the fat cells, but has the disadvantages of low purification efficiency and high loss of fat active components. In addition, all of the above three methods have problems in that the fat mixture is exposed to the air during the treatment, the risk of infection during the fat transplantation may increase, and the survival rate of the fat transplantation may decrease.
There are several approaches in the prior art that attempt to solve the above-mentioned problems. For example, CN 209092303U discloses a fat extraction and filling purification device, which mainly separates the fat tissue and active ingredients in the fat mixture from impurities by a filter screen. The fat mixture passes through the sieve under the action of gravity to remove water, blood cells, cell debris and medicinal components from the fat mixture, but the fat mixture has insufficient ability to remove lipid droplets. In addition, the fat mixture treated by the purification device still needs to be collected in an open environment. Thirdly, because the area of the filter screen in the purification device is limited, the purification device is easy to be blocked by adipose tissues in the using process, and the efficiency of fat treatment can be reduced or even failed.
For another example, patent application publication No. CN 104918641A discloses a fat treatment device, which mainly comprises a syringe-like structure combined with a filter and a super-absorbent material, wherein the filter separates adipose tissues and active ingredients in the fat mixture from impurities, and the absorbent material absorbs moisture in the fat mixture. The device realizes that the fat mixture is processed under the fully closed condition, but the device is combined with the structure of the syringe, the space of the device is limited, and the absorbent material mainly aims at the moisture in the fat mixture, and the fat drop components in the fat mixture cannot be effectively removed. In addition, the device needs to manually complete the suction, purification and collection of fat during the use process, so the fat extraction efficiency is low.

The invention relates to a purification method of a device for purifying and collecting autologous fat mixture, which comprises the following steps:

The invention has the beneficial effects that: the fat processor absorbs fat drops in the fat mixture, and the water in the fat mixture is processed by the water filter and the waste liquid bottle.
In the process that the fat mixture flows through the fat processor and enters the oil filter, because the aperture of the first filter screen is smaller than that of fat cells and fat active ingredients and larger than that of water and fat drops, the fat cells and the fat active ingredients are blocked in the inner cavity pipe of the oil suction pipe by the first filter screen, the fat drops, the water and cell fragments are distributed on two sides of the first filter screen in a balanced manner, but as the fat drops are attached by the oil suction material, the content of the fat drops in the mixed liquid is gradually reduced; part of water flows to the water filter along with the fat mixture, and the other part of water passes through the oil absorption layer and the supporting layer and enters the waste liquid bottle through the liquid discharge pipe. After the fat mixture without fat drops enters the inner cylinder of the water filter, the fat cells and the fat active ingredients are blocked by the second filter screen again due to the problem of pore size, and the water can freely pass through the second filter screen and is adsorbed by the water absorption layer on the outer side of the second filter screen, so that the inner cylinder of the water filter is filled with the purified fat cells and the fat active ingredients. The fat collector can be fully filled with purified fat cells and fat active ingredients through a fat collecting pipeline connected with the fat collector.

s1, respectively connecting a three-way joint with a liposuction channel and a transfusion channel; connecting the fat collection conduit to a fat collector; respectively connecting a first negative pressure interface on the top cover of the water filter and a second negative pressure interface on the waste liquid bottle with a negative pressure source, and opening regulating valves on the first negative pressure interface and the second negative pressure interface;
s2, the grease processor sucks the fat mixture under the action of negative pressure, and the fat mixture enters an inner cavity pipe of the grease processor; fat drops in the fat mixture pass through the pipe wall of the inner cavity pipe and the first filter screen and are absorbed by the oil absorption layer, and meanwhile, moisture in the fat mixture is freely distributed in the fat processor, so that the fat mixture without the fat drops is obtained;
s3, when the fat mixture after being subjected to fat drop removal enters the tail end of the fat processor, under the action of a negative pressure source of a second negative pressure interface from the waste liquid bottle, part of moisture in the fat mixture after being subjected to fat drop removal enters the waste liquid bottle through a liquid discharge pipe, and the other part of moisture in the fat mixture after being subjected to fat drop removal enters an inner cylinder of the water filter along with the fat mixture after being subjected to fat drop removal;
s4, after entering the inner cylinder, water passes through the inner cylinder and the second filter screen and is absorbed by the water absorption layer; obtaining purified fat and fat stem cells;
and S5, extracting purified fat and adipose-derived stem cells by the adipose collector through the adipose collecting pipeline.
10. The method for purifying and collecting autologous fat mixture according to claim 9, wherein the apparatus comprises: after the step S4, the purified fat and the fat stem cells are gathered to the pipe orifice of the fat collecting pipeline through a push plate and a telescopic pushing mechanism in the inner cylinder, and then the step S5 is carried out.
