Description

Technical Field

[0001] The utility model belongs to the field of medical instruments and relates to an umbilical cord cutting device which has strong practicability and improves work efficiency. Background Art

[0002] The umbilical cord is 50-60cm long, 14.42±1.5mm in diameter, and weighs about 40g. The outer surface is covered with a single layer of amniotic membrane. Two arteries and one vein are located in the proteoglycan-rich Wharton's jelly (WJ). The structure of the umbilical cord includes the following components: amniotic epithelial cell layer, subamniotic layer, WJ and perivascular tissue. According to research reports, the phenotypes of MSC cells from different components are not consistent, and most studies do not mention which specific component of the umbilical cord is used to isolate and culture MSCs, which makes the research results incomparable. Currently, which components of umbilical cord tissue are most suitable for clinical application are still being explored.

[0003] Currently, the process of dividing the umbilical cord takes a lot of time. The longer the umbilical cord is treated in vitro, the weaker the cell activity and the cell multiplication rate are relatively weakened. The existing umbilical cord dividing device can easily cause the umbilical cord to slip off. When cutting, the blood in the umbilical cord splashes and easily contaminates the device.

[0031] One side of the box cover 2 is connected to one side of the box body 1 via a detachable slot shaft 6, so that the box cover 2 can be opened or closed, thereby achieving the segmentation of the umbilical cord.

[0032] The upper fixing parts 4 of the single umbilical cord are adjacently arranged upper fixing strips 4-2, and a gap (in this embodiment, the gap is 0.1 cm) is provided in the middle of the upper fixing strips 4-3 for accommodating the blade 5.
