Specific implementation mode
In the following, in conjunction with attached drawing, the syringe of the present invention is described in detail.
The syringe for sticky liquid of the present invention comprising:Cylinder 10, piston component 20, draw point 30.
Cylinder 10 is formed with air admission hole (not shown) and circular hole 13 in its second end, is formed on the internal perisporium of circular hole 13
There is internal thread;Cylinder can form around circular hole 13 and reinforce platform 12, to reinforce the robustness of circular hole 13.
Cylinder 10 its first end sidewall profile at thering is draw point pedestal 15, the first end of draw point pedestal 15 to be formed with silica gel
Pipe needle 17;Draw point combined hole 19 is formed in draw point pedestal;Draw point combined hole 19 is connected to silicone tube needle 17;It is close to cylinder 10
Connection through-hole 16 is formed on the inside of one end, 10 inside of cylinder is connected to by the connection through-hole 16 with draw point combined hole 19.
Piston component 20 includes piston head 21 and piston rod 24;Piston head 21 is that axis is rotationally incorporated in piston rod 24
The second end of the first end of piston rod 24, piston rod 24 is fixedly formed with colyliform handle 25;It is formed on the body of rod of piston rod 24
There is external screw thread;Piston head is contained in cylinder 10, and piston rod 24 extends to outside, and piston rod from the circular hole 13 of cylinder second end
The internal thread of 24 external screw thread and circular hole 13 meshes together;Piston rod 24 can form discoid boss 23 in its first end,
Piston head 21 can form round table-like combined hole 22 in its second side, and discoid boss 23 is rotationally incorporated in round table-like combination
In hole 22.
Draw point 30 is inserted in draw point combined hole 19 and silicone tube needle 17;The first end of draw point 30 forms tip 31, extends
To the outside of silicone tube needle 17;The second end of draw point 30 extends to the outside of 19 second end of draw point combined hole.
Silicone tube needle 17 is formed with multiple side openings 18 in its first end, to increase the number of delivery outlet.
Cylinder 10 is formed further with ultrasonic vibration generator 14 in its first end, to load ultrasound to the liquid in cylinder
Vibration, ultrasonic wave are propagated in liquid, are conducive to the increase of mobility of the liquid in the flow channel of relative narrowness, facilitate medicine
Liquid is rapidly introduced into patient body.
It is formed with internal thread on the inner wall of draw point combined hole 19;Draw point 30 does not extend the part outside silicone tube needle 17
External screw thread is formed on periphery;The external screw thread of draw point and the internal thread of the draw point combined hole mesh together to form sealing.
Draw point 30 is formed with lug boss 33 in its second end, to be conveniently operated.
In second embodiment, convex block is formed in the middle part of draw point;The first end of draw point combined hole forms front limit stop block, second end
Form rear positive stop.
The diameter of colyliform handle 25 is more than the overall diameter of cylinder 10.User's operation in this way is more effortless.
When being punctured, draw point is retained in silicone tube needle, is pierced into patient body together with silicone tube needle and draw point;So
After retract draw point so that connection through-hole is connected to silicone tube needle, and at this time by rotation colyliform handle, piston rod 24 is in circular hole 13
Precession pushes piston head to advance, and sticky liquid is squeezed out from connection through-hole, enters patient's body via silicone tube needle.In order to
The mobility for increasing thick liquid, can also use ultrasonic vibration generator.
The syringe for sticky liquid of the present invention is laborsaving when injecting sticky liquid, safe, and the earth facilitates shield
Scholar's injection operation.
