The invention discloses an unfreezing device for placental cells capable of indicating a recovering end point and a recovering method thereof. The device comprises a water bath kettle and a
cell-recovering device arranged in the water bath kettle, wherein the
cell-recovering device is equipped with a recovering box, a water purifying box and a control panel; the control panel is equipped with a power switch, a filtering
control switch, a temperature indicator, a
temperature control device and an alarming device; the filtering
control switch is used for controlling a water pump to work; a recovering fixed plate is arranged at the top of the recovering box; a fixing hole is formed on the surface of the recovering fixed plate; the hole shape and the hole
diameter of the fixing hole are respectively corresponding to the shape and size of a cryopreserving
pipe and a cryopreserving bag; and an elastic clamping sheet is arranged on the position, corresponding to the fixing hole, on the lower surface of the recovering fixed plate. According to the device and the method, a user does not need to hold the cryopreserving
pipe or the cryopreserving bag in the recovering process and the
automation is realized; the defect of manual
visual inspection required for checking if completing the recovering is overcome; the
pollution problem easily caused by water in water bath can be solved; and the recovering temperature consistency is promoted and the
cell activity is promoted.
