Description
Technical field
The utility model belongs to experiment equipment correlative technology field, and in particular to a kind of injection for being used to draw plaque
Device.
Background technology
Bacteriophage is a kind of virus that can infect bacterium, is largely existed in soil and water body, by infect soil and
Bacterium in water body declines its quantity, and the method for isolating and purifying bacteriophage in the lab is typically using double-layer plate culture
Method, the method need to choose bacteriophage.
At present, conventional method is chosen plaque using scalpel or toothpick, is easily entrained during experimental implementation
Host strain, moreover, imperfect with the plaque of scalpel or toothpick picking, the situation for being susceptible to plaque fragmentation leads to not
Picking, and operate time-consuming and laborious, it is also easy to bring miscellaneous bacteria into, it is many unfavorable to generate the progress of experiment.
There is the improvement much on syringe in patent document, such as：Chinese patent literature CN205982304U is disclosed
A kind of sterile injector of automatic loading suitable for chromatogram purification system and a small amount of repeatedly loading.Chinese patent literature
CN205569441U disclose it is a kind of can inserting needle control depth of needle and the quantitative automatic injector into medicine automatically.And on
The experiment equipment for drawing plaque also has patent document, such as：Chinese patent literature CN205182758U discloses a kind of new
For drawing the liquid transfer gun head of plaque.But on a kind of current for drawing the syringe of plaque of the utility model
It has not been reported..
Utility model content
The purpose of this utility model is to provide a kind of for drawing the syringe of plaque, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical solution：A kind of syringe for being used to draw plaque,
Including syringe cylinder, the circle centre position of described syringe cylinder one end is provided with hole head, and the syringe cylinder other end is provided circumferentially about has
Symmetrical injection handle, the syringe cylinder are internally provided with piston, and the circle centre position of the piston sets oriented injection
The piston rod of one end extension of handle, the other end of the piston rod are provided with injection pushing hands.
Preferably, the length of the syringe cylinder is 40mm, and the total length of the piston rod is 60mm.
Preferably, length of the piston rod outside syringe cylinder is 20mm.
Preferably, the length of the hole head is 10mm, and the internal diameter of hole head lowermost end has tetra- kinds of 1mm, 2mm, 3mm and 4mm
Specification.
Preferably, the hole head and syringe cylinder integrated injection molding, and hole head is conical structure.
Preferably, the provided circumferentially about of the syringe cylinder has graduation mark.
Compared with prior art, the beneficial effects of the utility model are：
1st, the syringe of the utility model, it is simple in structure, it is easy to use, pollution is reduced, picking that can quickly, safe is bitten
Bacterial plaque.
2nd, the syringe of the utility model is used to draw the liquid transfer gun head enhanced convenience of plaque in contrast to utility model
Fast, liquid transfer gun head needs to control dynamics during plaque is drawn, if dynamics is too small, plaque may adhesion
On tablet, it is not easy to draw；If dynamics is excessive, then plaque may be inhaled into liquid-transfering gun, so that liquid-transfering gun is subject to
Pollution, causes damages；The syringe of the utility model does not have to deliberately control dynamics, more quick and safe completely can draw and bites
Bacterial plaque.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides following technical scheme：A kind of syringe for being used to draw plaque, bag
Syringe cylinder 4 is included, the circle centre position of 4 one end of syringe cylinder is provided with hole first 3, and 4 other end of syringe cylinder is provided circumferentially about phase
Mutually symmetrical injection handle 6, syringe cylinder 4 are internally provided with piston 2, and the circle centre position of piston 2 sets oriented injection handle 6
The piston rod 5 of one end extension, the other end of piston rod 5 are provided with injection pushing hands 7.
Embodiment one：
A kind of syringe for drawing plaque, with reference to shown in Fig. 1, including the note having in syringe cylinder 4, syringe cylinder 4
Emitter piston rod 5 and piston 2, the connection relation between three is identical with the structure of known syringe, and therefore not to repeat here.
