Specific implementation mode
Below in conjunction with attached drawing, the technical characteristic and advantage above-mentioned and other to the present invention are clearly and completely described,
Obviously, described embodiment is only the section Example of the present invention, rather than whole embodiments.
In one embodiment, as shown in Figure 1.Present embodiments provide disposable syringe for veterinary use comprising syringe 1,
Push rod 2 and injection needle 3.Also, push rod 2 is set in syringe 1；Injection needle 3 is sleeved on syringe 1；The inner wall of syringe 1 is equipped with ring
Shape slot 11, opening 12 of the annular groove 11 close to syringe 1；The length of push rod 2 is less than the length of syringe 1, and the end 21 of push rod 2 is in circle
The end 21 of sheet, push rod 2 is flexible piece, and 21 radius of end of push rod 2 is more than the inner radial of syringe 1 and is less than annular groove
11 inner radial；Wherein, when push rod 2 is completely into in syringe 1, the end 21 of push rod 2 is embedded in annular groove 11, makes to push away
Bar 2 is kept completely into the state in syringe 1.
In the present embodiment, disposable syringe for veterinary use is during primary complete use, need by push rod 2 completely into
Enter into syringe 1, to squeeze out the liquid medicine in syringe 1.But since the end of push rod 2 21 in disc-shaped and is
Flexible piece.So when push rod 2 is completely into in syringe 1, the end 21 of push rod 2 is embedded in annular groove 11, and makes push rod
2 keep completely into the state in syringe 1.At this time the end 21 of push rod 2 relative to the opening 12 of syringe 1 be in indent,
So can not extract.
In one embodiment, as shown in Figure 1.Disposable syringe for veterinary use is present embodiments provided, further includes needle body
External member 4；Needle body external member 4 is cylindrical in shape, and one end of needle body external member 4 provides injection needle 3 and is fixedly connected, and the other end of needle body external member 4 carries
It is detachably connected for syringe 1.
In the present embodiment, injection needle 3 can be removed from syringe 1.It is realized particular by needle body external member 4.It is real
On border, needle body external member 4 is also common in current injector for medical purpose.
In one embodiment, needle body external member 4 is moulding.
In one embodiment, the end outer peripheral edge of syringe 1 is equipped with a circle external screw thread, and the inner peripheral of needle body external member 4 is equipped with
One circle internal thread, the other end of needle body external member 4 provide syringe 1 and are threadedly coupled.
In the present embodiment, needle body external member 4 can be mounted on syringe 1 by only one circle of rotation, very convenient.
In one embodiment, as shown in Figure 2.Disposable syringe for veterinary use is present embodiments provided, further includes rubber
First 5.Rubber end 5 is sheathed on the other end of push rod 2；Rubber end 5 include set gradually first annular raised 51, it is first annular
Groove 52, the second annular protrusion 53, second annular groove 54 and third annular protrusion 55.
In the present embodiment, coordinate push rod 2 by the way that Rubber end 5 is arranged.Specifically, the Rubber end 5 in the present embodiment is special
Fixed, because it includes first annular raised 51 set gradually, first annular groove 52, the second annular protrusion 53, the second ring
Connected in star 54 and third annular protrusion 55.So there are very big deformation spaces on the length direction along push rod 2.
Especially spaced first annular groove 52 and second annular groove 54 provide 5 very big deformation space of Rubber end.
So after the liquid medicine in syringe 1 is squeezed out completely, push rod 2 is not completely into in syringe 1.And continue to exert a force, it can make
Push rod 2 is completely into in syringe 1, and the end 21 of push rod 2 is embedded in annular groove 11.So by the way that the present embodiment is arranged
In Rubber end 5, on the one hand the liquid medicine in syringe 1 can be squeezed out completely, on the other hand can be in the liquid in syringe 1
Drug makes the end 21 of push rod 2 be embedded in annular groove 11 after squeezing out completely.
In one embodiment, as shown in Figure 2.Rubber end 5 further includes buffer cavity（It is not shown in figure）；Buffer cavity is set
In the first annular raised 51, inside of the second annular protrusion 53 and third annular protrusion 55, buffer cavity provides first annular
Raised 51, second annular protrusion 53 and third annular protrusion 55 buffer radially, and buffer cavity also provides first annular recessed
Slot 52 and second annular groove 54 buffer in the axial direction.
In the present embodiment, by the way that buffer cavity is arranged in the inside of Rubber end 5, injection effect can further be improved
And fixed effect, i.e., on the one hand the liquid medicine in syringe 1 can be squeezed out completely, it on the other hand can be in the liquid in syringe 1
Body drug makes the end 21 of push rod 2 be embedded in annular groove 11 after squeezing out completely.
In addition, in one embodiment, Rubber end 5 further includes buffer cavity（It is not shown in figure）, also, 5 face of Rubber end
It is less than sidewall thickness of the Rubber end 5 backwards to the end of push rod 2, the other end packet of push rod 2 to the sidewall thickness of the end of push rod 2
Include exhaust hole（It is not shown in figure）, the opening direction of exhaust hole and is perpendicularly oriented to rubber along the length direction of push rod 2
The side wall of first 5 ends towards push rod 2；Wherein, when Rubber end 5 is squeezed and broken, exhaust hole provides the gas in buffer cavity
From the channel being discharged backwards to the side of injection needle 3.In the present embodiment, disposable syringe for veterinary use was once completely using
Cheng Zhong is needed push rod 2 completely into in syringe 1, to squeeze out the liquid medicine in syringe 1.And in the above process
It is middle to rack Rubber end 5, to make the syringe for veterinary use can not be used again.Because the inside of Rubber end 5 has buffer cavity,
And it needs to apply certain power during squeezing push rod 2.So can be non-in the case where 5 sidewall thickness of Rubber end differs
It is often easy to rack the smaller side wall of thickness.And the air in buffer cavity is discharged from backwards to the side of injection needle 3, avoids
The animal cured is had an impact.
Particular embodiments described above has carried out further the purpose of the present invention, technical solution and advantageous effect
It is described in detail, it should be understood that the above is only a specific embodiment of the present invention, the protection being not intended to limit the present invention
Range.It particularly points out, to those skilled in the art, all within the spirits and principles of the present invention, that is done any repaiies
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
