Description
Technical Field
The utility model discloses a device for purifying and collecting autologous fat mixture.
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 aims 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 prior art approaches that attempt to solve the above problems. For example, the utility model publication No. CN 209092303U discloses a fat pumping 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 purifying device is limited, the purifying device is easy to be blocked by adipose tissues in the using process, so that the efficiency of the adipose treatment can be reduced and even the purifying device fails.
For another example, patent application publication No. CN 104918641 a discloses a fat treatment device, which is mainly combined in a syringe-like structure by a strainer and a super absorbent material, wherein the strainer separates the fat tissue 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.
