Abstract
The utility model relates to an external cell collector that food medicine detection used is by syringe 1, constitutes with collection needle 3 with 1 hose that links to each other 2 of syringe, its characterized in that: syringe 1 comprises urceolus 4 and piston rod 5 and the piston 6 of fixing tip in the piston rod, and swing handle 7 has been installed in outer end department to piston rod 5, and at syringe head department intercommunication hose, hose end in addition feeds through the collection needle. Round pin excellent 8 is inserted in the pinhole at syringe afterbody edge, when the round pin stick inserts deeply, and the external screw thread interlock of round pin stick and piston rod for the piston rod can not spur, but through rotatory swing handle, can be so that around the piston rod slow the removal, at the top of syringe setting valve. The beneficial effects of the utility model are that: through the control of selling the stick for large area's cell can enough need be absorb in the control of being convenient for of the negative pressure of syringe, cell that again can accurate absorption small region, tens cells even.
Description
Technical field
The utility model relates to a kind of Cell collection device, particularly a kind of cell in vitro collector of food and medicine analysis.
Background technology
Need to cultivate zooblast or human body cell in vitro in food and medicine analysis field at present, 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 accurately drawing the aspects such as cell in food and medicine analysis process.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cell in vitro collector of food and medicine analysis, its negative pressure is convenient to control, the cell drawing large regions can either be needed, accurately can draw again the cell of zonule, even tens cells, so that food and medicine analysis is used.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of cell in vitro collector of food and medicine analysis, by syringe 1, the flexible pipe 2 be connected with syringe 1 and collect pin 3 and form, it is characterized in that: 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 flexible pipe at syringe nozzle place, flexible pipe another end is communicated with collects pin.Pin rod 8 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.Valve 9 is set at the top of syringe 1, when drawing cell and being complete, valve 9 is closed, prevents enchylema from outflowing.
The beneficial effects of the utility model are: by the control of pin rod, make 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.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described pin rod is 2-4 root.
Further, the externally threaded length of described piston rod is 3-8cm.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
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 utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of cell in vitro collector of food and medicine analysis, by syringe 1, the flexible pipe 2 be connected with syringe 1 and collect pin 3 and form, it is characterized in that: 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, is communicated with flexible pipe at syringe nozzle place, and flexible pipe another end is communicated with collects pin.Pin rod 8 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.Valve 9 is set at the top of syringe 1, when drawing cell and being complete, valve 9 is closed, prevents enchylema from outflowing.
Further, described pin rod is 2-4 root.
Further, the externally threaded length of described piston rod is 3-8cm.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
