The syringe needle includes needle tubing and needle stand, and the thin two-stage stepped hole of the thick other end in one end, institute are offered on the needle stand
State and form step surface between the thick section of two-stage stepped hole and thin segment, the thick section extend internally far from one end inner wall of thin segment have with
The thick section of the protrusion that sliding slot matches, the two-stage stepped hole is set in connecting tube, before the protrusion is against annular slot
On the wall of end side, the step surface be equipped with rubber pad, the rubber pad swelling between step surface and the front end surface of connecting tube,
The needle tubing is fixed on the front end of needle stand and is connected to the thin segment of two-stage stepped hole.
When being set in the thick section of two-stage stepped hole on needle stand in connecting tube in this programme, first by the protrusion of needle stand along even
The sliding slot of adapter tube is moved to annular slot, then rotates needle stand, so that protrusion is located in annular slot, rubber pad generates elasticity and becomes
Shape is pressed between the step surface of needle stand and the front end surface of connecting tube, plays the role of density, bullet of the needle stand in rubber pad
Protrusion under power effect thereon is firmly against on the front end side of annular slot, plays the work being fixed on needle stand in connecting tube
With；Wherein annular slot opens up not only to fixed needle stand, also makes connecting tube become thin at the position where annular slot
Weak position is easy to fracture, and after the syringe uses once, connecting tube can fracture, effectively avoid the repetition of syringe
It uses, avoids syringe and picked by other people and sell caused cell contamination again.
For the ease of after syringe uses once, convenient for fractureing, further, the axial length of the annular slot is big
In length of the protrusion on needle stand axis direction.
Preferably, the needle tubing and needle stand are integrally formed.
Further, the outer peripheral surface of the needle stand has radially extended handle, when fractureing connecting tube, can a hand hold
Syringe, another hand move handle, avoid hand and contact syringe needle and the caused risk for breaking private seal.
The beneficial effects of the utility model are: its syringe needle of the disposable Cell Micro-injection Device of the utility model can be firm fixation
In the connecting tube of syringe, good seal performance is not easily to fall off, and connecting tube is easy to fracture, after using once convenient for syringe
Self-destruction.

It can be only used for helping the description to the feature in attached drawing with referring to (for example, upper and lower, left and right, etc.).Therefore, it is not limiting
Following specific embodiments are used in property meaning processed, and are only requested by appended claims and its equivalent form to limit
The range of the theme of protection.
Embodiment 1
As shown in Figure 1-3, a kind of disposable Cell Micro-injection Device, including syringe 1, syringe needle, push rod 3 and piston 4, piston 4 are sliding
Dynamic to be arranged in syringe 1, push rod 3 is fixedly connected with piston 4, and 1 front end of syringe is outward extended with and its internal connecting tube being connected to
The forward end of 1-1, connecting tube 1-1 offer sliding slot 1-11 along its axis direction, and the outer peripheral surface of connecting tube 1-1 offers annular
Card slot 1-12, sliding slot 1-11 are connected to annular slot 1-12；
Syringe needle includes needle tubing 5 and needle stand 2, and the thin two-stage stepped hole of the thick other end in one end, two-stage ladder are offered on needle stand 2
Step surface 2-3 is formed between the thick section 2-1 and thin segment 2-2 in hole, thick section 2-1 extends internally far from one end inner wall of thin segment 2-2 to be had
The thick section 2-1 of the raised 2-11 to match with sliding slot 1-11, two-stage stepped hole are set on connecting tube 1-1, and raised 2-11 is against
In the front end side wall of annular slot 1-12, step surface 2-3 be equipped with rubber pad 6,6 swelling of rubber pad step surface 2-3 with connect
Between the front end surface of pipe 1-1, needle tubing 5 is fixed on the front end of needle stand 2 and is connected to the thin segment 2-2 of two-stage stepped hole.
