Problems solved by technology
[0003] At present, modern technology uses stem cell culture or extracts stem cells from the umbilical cord. When extracting stem cells from the umbilical cord, a stem cell puncture extractor is used to pass through the umbilical cord eye of the human body and draw blood from the umbilical cord. Stem cells are isolated, but in this process, the general stem cell puncture extractor is directly inserted into the human body, and fixed through the human skin with needles and threads to prevent the stem cell puncture extractor from tipping over, causing unnecessary pain to the human body, and at the same time causing the loss of umbilical cord blood , this will cause secondary harm to the recipient, so we have introduced a stem cell puncture extractor that prevents the stem cell from being dumped when collecting umbilical cord blood, so as to solve this problem

The invention relates to the technical field of stem cells, and discloses a stem cell puncture extractor capable of avoiding falling during umbilical cord blood collection. The stem cell puncture extractor capable of avoiding falling during umbilical cord blood collection comprises a drawing head, a fixed component and a placement component, wherein the bottom end of the drawing head is fixedly provided with an insertion tube; the outer wall of the insertion tube is fixedly connected with the inner wall of the fixed component; the outer wall of the fixed component and the inner wall of the placement component are movably connected; after the position of each outer rubber sheet is determined, each outer ring is upwards pulled so as to enable each outer ring to drive each movement box to upwards move to pull each pulling rod; then, each pulling rod pulls each extraction plug, each connecting rod is driven to pull each inner rubber sheet to upwards move so as to draw out gas in each outer rubber sheet, and each outer rubber sheet is tightly fit to the human body so as to fix the position of the insertion tube to prevent the insertion tube from falling; and meanwhile, each extrusion plate is positioned below each supporting block, each extrusion plate is affected by each second spacing rod and can not swing to the bottom end direction of each supporting tube, the supporting blocks can not extrude the extrusion plates to swing, and therefore, the height position of each movement box is fixed.
Description
technical field [0001] The invention relates to the technical field of stem cells, in particular to a stem cell puncture extractor which prevents the stem cell from being dumped when collecting umbilical cord blood. Background technique [0002] Stem cells are a kind of miraculous cells that can differentiate into different tissue cells by themselves, such as bone cells, muscle cells, etc. This means that stem cells can supplement the miraculous cells of the cell source when the human body is damaged. Modern medical scientists have been devoting themselves to the research of stem cells in order to solve some incurable diseases through stem cells. [0003] At present, modern technology adopts stem cell culture or extracts stem cells from the umbilical cord. When extracting stem cells from the umbilical cord, a stem cell puncture extractor is used to pass through the umbilical cord eye of the human body and draw blood from the umbilical cord. Stem cells are isolated, but in t...
