Description
Technical field
The utility model is specifically related to a kind of infusion pump syringe.
Background technique
Syringe is to divide three-member type and two-piece type, three-piece construction is core using made of macromolecule polypropylene material
Bar, rubber plug, three, housing and injection needle, outer packing composition, two-part construction are core bar, housing and injection needle, outer packing composition.
In general infusion pump can directly adopt syringe and directly use, and not have individual spare part, but in our use processes
It can find existing syringe, it is inaccurate to use injection volume, if size matching problem, will lead to and push away after injection
Bar continues to promote, so as to cause other problems such as equipment losses.
Summary of the invention
In view of the above-mentioned problems of the prior art, the utility model provides a kind of infusion pump syringe.
To achieve the goals above, the technical solution adopted in the utility model is: a kind of infusion pump syringe, including cylinder
And core bar, cylinder front are equipped with injection port；Core bar is threadedly coupled with cylinder inner surface；Core bar is divided into head and the body of rod, outside head
Surface vertical orientation is equipped with screw rod, is fixedly connected in the middle part of the body of rod by threaded post, and threaded post is equipped with torsion slight crack, on the body of rod
Surface is threaded with end cap, and end cap upper surface central area vertical orientation is equipped with hexagonal prismatic grooves.
Preferably, the central axes of injection port and the central axes of cylinder are on same straight line.
Preferably, the central axes of screw rod and the central axes of cylinder, on same straight line, screw rod and injection port are inserted
Formula connection is pulled out, screw rod main surface is uniformly provided with through-hole.
Preferably, the tapered structure of cylinder inside bottom surface.
Preferably, end cap lower surface vertical orientation is equipped with first annular protrusion, the lower surface of first annular protrusion and cylinder
Body upper surface is in the same plane.
Preferably, barrel outer surface lower end is equipped with first through hole, rubber stopper is equipped in first through hole；The body of rod tail portion
Outer surface is equipped with circular protrusion.
Compared with the prior art, the advantages of the utility model are:
1. core bar is threadedly coupled with cylinder inner surface, the tapered structure of cylinder inside bottom surface, by the way of screw thread propulsion,
Control supply amount that can be more accurate；
2. core bar is divided into head and the body of rod, head exterior surface vertical orientation is equipped with screw rod, passes through threaded post in the middle part of the body of rod
It is fixedly connected, threaded post, which is equipped with torsion slight crack, since torsion is excessive, can realize threaded post when being advanced to bottommost
Fracture, avoids equipment from being damaged under reaction force；
3. body of rod upper surface is threaded with end cap, it is recessed that end cap upper surface central area vertical orientation is equipped with hexagonal prismatic
Slot, split type structure, disassembly is simple, effectively save cost；
4. whole design is novel, practicability is high, and supply amount is stablized, and security performance is high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model infusion pump syringe.
Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
Such as Fig. 1, a kind of infusion pump syringe, including cylinder 1 and core bar 3,1 front of cylinder are equipped with injection port 2；Core bar 3 with
1 inner surface of cylinder is threadedly coupled；Core bar 3 divides for head and the body of rod, and head exterior surface vertical orientation is equipped with screw rod 32, in the body of rod
Portion is fixedly connected by threaded post 31, and threaded post 31 is equipped with torsion slight crack, when being advanced to bottommost, due to torsion mistake
Greatly, it can realize that threaded post 31 is broken, equipment is avoided to be damaged under reaction force, body of rod upper surface is threaded with end cap 4,
4 upper surface central area vertical orientation of end cap is equipped with hexagonal prismatic grooves, and split type structure, disassembly is simple, effectively save cost.
The central axes of injection port 2 and the central axes of cylinder 1 are on same straight line.The central axes of screw rod 32 and the central axes of cylinder 1
On same straight line, screw rod 32 is connect with 2 plug-in of injection port, and 32 main surface of screw rod is uniformly provided with through-hole.In cylinder 1
The tapered structure in side bottom surface, by the way of screw thread propulsion, control supply amount that can be more accurate.4 lower surface of end cap is vertical
Orientation is equipped with first annular protrusion 41, and the lower surface and 1 upper surface of cylinder of first annular protrusion 41 are in the same plane.Cylinder
1 outer surface lower end is equipped with first through hole, is equipped with rubber stopper in first through hole；Body of rod trailing exterior surface is equipped with circular protrusion.
As shown in Figure 1,1 outer surface of cylinder is also provided with sucker, be conducive to using when fix.In one embodiment,
Such as Fig. 1, core bar 3 divides for head and the body of rod, and head exterior surface vertical orientation is equipped with screw rod 32, passes through threaded post 31 in the middle part of the body of rod
It is fixedly connected, threaded post 31 is equipped with torsion slight crack, when being advanced to bottommost, due to continuing to rotate, so torsion mistake
Greatly, it can realize that threaded post 31 is broken, carry out idle running, equipment is avoided to be damaged under reaction force.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.The utility model will not be limited to the embodiments shown herein, but to accord with principles disclosed herein and
The consistent widest scope of features of novelty.
