Abstract
The present invention relates to a kind of cell harvesting pin, by syringe 1, the flexible pipe 2 be connected with syringe 1 with collect pin 3 and form, syringe 1 is made up of urceolus 4 and piston rod 5 and the piston 6 that is fixed on piston rod inner end, piston rod 5 outside end is equiped with swing handle 7, be communicated with one end of flexible pipe 2 at the head place of syringe 1, the other end of flexible pipe 2 is communicated with collects pin 3.Pin rod 8 is inserted in the pin-and-hole of syringe 1 tail edge, and when pin rod 8 inserts deeply, pin rod 8 is engaged with the outside screw of piston rod 5, and piston rod 5 can not be pulled, but passes through the swing handle of rotating dog rod 8, can make slowly movement before and after piston rod 5.The present invention, by the control of pin rod, makes the negative pressure of syringe be convenient to control, can either need the cell drawing large regions, accurately can draw again the cell of zonule, even tens cells.
Description
Technical field
The present invention relates to a kind of Cell collection device, particularly a kind of cell harvesting pin.
Background technology
At present in cell engineering field, normal employing culturing bottle culturing cell, sometimes needs the cell of a certain large regions of culturing bottle to draw out, and sometimes needs zonule, even tens cells.Gather cell conventional apparatus and be mainly hydrocone type collector, traditional gathering device, owing to being difficult in vacuum magnitude control, accurately cannot draw the cell in a certain region.Before using conventional apparatus operation in addition, the training time is longer, and be difficult to grasp, very easily produce fatigue in operating process, therefore conventional apparatus cannot meet the demand of the aspects such as embryo engineering field research and teaching.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cell harvesting pin, and its negative pressure is convenient to control, and can either need the cell drawing large regions, accurately can draw again the cell of zonule, even tens cells.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A kind of cell harvesting pin, by syringe, the flexible pipe be connected with syringe with collect pin and form, syringe is made up of urceolus and piston rod and the piston that is fixed on piston rod inner end, piston rod outside end is equiped with swing handle, be communicated with one end of flexible pipe at syringe nozzle place, the other end of flexible pipe is communicated with collects pin.Pin rod is inserted in the pin-and-hole of syringe tail edge, and when pin rod inserts deeply, pin rod is engaged with the outside screw of piston rod, and piston rod can not be pulled, but by rotating swing handle, can make slowly movement before and after piston rod.
The invention has the beneficial effects as follows: by the control of pin rod, make the negative pressure of syringe be convenient to control, the cell drawing large regions can either be needed, accurately can draw again the cell of zonule, even tens cells.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the quantity of described pin rod is 2-4 root.
Further, the externally threaded length of described piston rod is 3-8cm.
Take the beneficial effect of technique scheme: the negative pressure in syringe can be controlled more flexibly, accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In accompanying drawing, the list of parts representated by each label is as follows:
1, syringe, 2, flexible pipe, 3, collect pin, 4, urceolus, 5, piston rod, 6, piston, 7, swing handle, 8, pin rod.
Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of cell harvesting pin, by syringe 1, the flexible pipe 2 be connected with syringe 1 with collect pin 3 and form, syringe 1 is made up of urceolus 4 and piston rod 5 and the piston 6 that is fixed on piston rod 5 inner end, piston rod 5 outside end is equiped with swing handle 7, be communicated with one end of flexible pipe 2 at the head place of syringe 1, the other end of flexible pipe 2 is communicated with collects pin 3.Pin rod 8 is inserted in the pin-and-hole of syringe 1 tail edge, and when pin rod 8 inserts deeply, pin rod 8 is engaged with the outside screw of piston rod, and piston rod can not be pulled, but by rotating swing handle 7, can make slowly movement before and after piston rod 5.
Preferably, the quantity of described pin rod 8 is 2-4 root.
The externally threaded length of described piston rod 5 is 3-8cm.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
