Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model as shown in the figure,
Prepare for micro-cast-off cells the Combined centrifuge tube that cytology wax stone is used, comprise special embedding box for dehydrating 6, it is characterized in that, also comprise push pipe 4, cell lump collection excipient pipe 2, the bottom tube 5 of transparent material;
Described push pipe 4 is siphunculus, and wherein push pipe one end internal-and external diameter closes up simultaneously, and external diameter is provided with screw thread;
The excipient pipe 4 that described cell lump collection excipient pipe 2 is fixed head and fixed head internal diameter same diameter forms, and the internal-and external diameter of fixed head is identical with push pipe closing in end internal-and external diameter, and fixed head is also provided with symmetrical clamp through hole 3;
Described bottom tube 5 is semicircle chondritic, its disc is provided with inner tube 9, described inner tube is top and the bottom, top is divided into large-diameter pipe, bottom is divided into small diameter tube, large-diameter pipe internal diameter is identical with cell lump collection excipient pipe 2 external diameters, and small diameter tube is identical with cell lump collection excipient pipe 2 internal diameters, and in large footpath, tube portion is provided with the screw thread matching with push pipe 1 closing in end screw thread;
Described special embedding box for dehydrating middle part is provided with excipient pipe embedding casting hole 7, is respectively equipped with a pair of arc piece deck 8 identical with cell lump collection excipient pipe 2 outside dimensions in special embedding box for dehydrating 6 inner sides, bottom surface with the putting hole periphery in outside.
Prepare for micro-cast-off cells the Combined centrifuge tube that cytology wax stone is used according to described, it is characterized in that, described excipient pipe 4 is for to make with plastic sheeting or the biomaterial built up membrane of micropore.
As Fig. 1 push pipe and bottom tube are threaded (or draw-in groove), after spinning, make that push pipe, cell lump are collected excipient pipe, bottom tube forms a Unified Global.
Cell lump collection excipient pipe 2 forms contact with push pipe 1 and is connected, cell lump is collected the hole that the fixed head of excipient pipe 2 is corresponding with push pipe bottom except center, separately offer more than 2 perforate, convenient operation person uses tweezers clamping mobile, excipient pipe 4 forms and (requires and together embedded section of cell lump by biomaterial or with aperture plastic sheeting material, do not affect chipping qualities), excipient pipe 4 can not separation with firm connection of fixed head.Bottom tube 5 base seals, internal volume and figuration pipe 4 match, and top is with the screw thread (or draw-in groove) matching with push pipe bottom thread (or draw-in groove); Push pipe is collected between excipient pipe fixed head and bottom tube push pipe bottom, cell lump after relying on screw thread (or draw-in groove) to be connected with bottom tube and is produced certain pressure, and makes whole tube wall have certain antiseepage leakproofness.When push pipe separates with bottom tube, use tweezers clamping to collect excipient pipe top tie plate, after taking-up, enter preparation flow.
