Problems solved by technology

However, the volume of living tissue is very small, and it is impossible to separate the living body from the tissue centrifugation in the original way. Even if centrifugation can be performed, the biological tissue is exposed to air pollution, or body fluid or fat of the body tissue during centrifugation. Difficult to clear

Embodiment Construction

[0040] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Components in each drawing are assigned reference signs, and the same component exists in the same form as much as possible even if it is shown in other drawings. In addition, in the description of the embodiment, if the specific description of the related structure or technology affects the understanding of the embodiment, the detailed description may be omitted.

[0041] In addition, terms such as first, second, A, B, a, b, etc. may be used when describing the constituent elements of the embodiment.

[0042] These terms are only used to distinguish its constituent elements from other constituent elements, and do not limit the essence, order or sequence, etc. of the corresponding constituent elements based on the terms. When a constituent element is marked "connected", "connected" or "connected", its constituent elements may be directly connected or connected to other...

Abstract

A piston for centrifugation according to one embodiment may comprise: a body; a valve which can move inside the body to the front side and the rear side of the body according to an applied external force; and a valve support having a fluid channel through which a fluid flows from the front side of the body to the rear side of the body and which guides movement of the valve.

Description

technical field [0001] Embodiments of the present disclosure relate to a piston for centrifugal separation. Background technique [0002] Biological tissue obtained by absorption or incision contains a large amount of fat, blood, body fluid, etc., and is generally used by centrifugation. However, the volume of living tissue is very small, and it is impossible to separate the living body from the tissue centrifugation in the original way. Even if centrifugation can be performed, the biological tissue is exposed to air pollution, or body fluid or fat of the body tissue during centrifugation. It is difficult to clean up etc. Therefore, a structure in which living tissue (such as adipose tissue) is centrifuged to remove impurities from the adipose tissue to obtain pure adipose tissue is being developed. For example, Korean Patent Publication No. 10-2014-0040050 discloses a double liposuction device. Contents of the invention [0003] technical issues [0004] According to ...
