Description
Technical field
Enter the present invention relates to a kind of liquid medium injector technical field, especially a kind of achievable equivalent, quantitative and even
The liquid medium injector of note.
Background technology
Traditional syringe is mostly that operating personnel are directly manually operated, and user is laborious and fltting speed is uneven, and
Due to operating personnel's vision and the influence of the aspect error such as manually, the liquid medium flow rate of per injection fail with exact equal amount,
Quantitative method is controlled, just like the uncontrollability that such destabilizing factor presence will certainly improve result, for science
The fields such as research, industrial production, therapeutic treatment will cause immeasurable serious consequence.
Therefore, it is badly in need of a kind of order masses for reducing even elimination operating personnel's many errors in practical operation to expect
A kind of achievable equivalent, quantitative and even enter the liquid medium injector of note.
The content of the invention
The present invention provides the liquid medium injector that a kind of achievable equivalent, quantitative and even enter note, to solve above-mentioned background
The problem proposed in technology, simple structure is practical, is conducive to popularization and application.
Technical problem solved by the invention is realized using following technical scheme:It is a kind of achievable equivalent of the present invention, fixed
Amount uniformly enters the liquid medium injector of note, including injector shell, and boosting wheel is provided with described injector shell, described
The hollow position of boosting wheel be provided with through hole, screw rod is provided with described through hole, described through hole and screw rod is connected through a screw thread, institute
The screw rod end stated is fixed on connecting pin, and described connecting pin is connected on the convex edge of injector shell rear inside wall, described
Connecting pin rearward end connection rotary handle, described injector case nose is provided with locking cap, described connecting pin outer surface
Packing ring is provided with injector outer casing back.
Described injector shell uses movable connection method with locking cap.
Described injector shell is clamping or threaded connection with the connected mode of locking cap.
Described injector case surface is provided with graduation mark show bar.
Described injector shell uses micro- dumbbell shape structure.
Beneficial effects of the present invention are:
1st, it is convenient and strength-saving using rotational structure propulsion mode, manipulation strength is reduced, improve operating efficiency;
2. the push mode of rotation ensure that to inject speed uniform, flow exact equal amount, quantitative, easy to operate, greatly reduce
Operating error, increased the accuracy of result.
3. the injector shell of micro- dumbbell shape meets principle of human engineering, increases the comfort of operator.
4. the graduation mark positioned at injector case surface indicates to be conducive to operator to total effective control for pushing rate-of flow
System.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
The present invention is described further below in conjunction with accompanying drawing:The liquid that a kind of achievable equivalent, quantitative and even enter note is situated between
Matter injector, including injector shell 3, boosting wheel 2, the described hollow position of boosting wheel 2 are provided with described injector shell 3
Through hole 7 is installed, screw rod 6 has been provided with described through hole 7, described through hole 7 and screw rod 6 has been connected through a screw thread, described screw rod 6
End is fixed on connecting pin 5, and described connecting pin 5 is connected on the convex edge of the rear inside wall of injector shell 3, described connection
The rearward end of pin 5 connects rotary handle 1, and the described front end of injector shell 3 is provided with locking cap 4.The described outer surface of connecting pin 5 and
The rear end of injector shell 3 is provided with packing ring 8.Described injector shell 3 uses movable connection method with locking cap 4.Described pushes away
Note device shell 3 is clamping or threaded connection with the connected mode of locking cap 4.The described surface of injector shell 3 is provided with graduation mark
Show bar.Described injector shell 3 uses micro- dumbbell shape structure.
When injecting liquid, the screw rod 6 for being installed on connecting pin 5 is driven to rotate by the rotary handle 1 for rotating rear portion, Ran Houan
Pushed ahead therewith loaded on the boosting wheel 2 inside injector shell 3, complete the propulsion work to liquid medium syringe.Wherein,
Packing ring 8 can reduce the frictional resistance between part in bolus infusion processes, the rotational structure of rotary handle 1 not only ensure that liquid etc.
Amount, quantitative and even enter note, greatly reduce operating error, and doctor need not see injector when in use, but by rotation
The amount of liquid that judgement is injected, facilitates operation technique.Rotation push mode of the invention reduces manipulation strength.
The present invention uses rotational structure propulsion mode, convenient and strength-saving, reduces manipulation strength, improves operating efficiency;Rotation
The push mode for turning ensure that to inject speed uniform, flow exact equal amount, quantitative, easy to operate, greatly reduce operating error,
Increased the accuracy of result;The injector shell 3 of micro- dumbbell shape meets principle of human engineering, increases the comfort of operator;
Graduation mark positioned at the surface of injector shell 3 indicates to be conducive to operator to total effective control for pushing rate-of flow.
Finally illustrate, choose above-described embodiment and it has been described in detail and description is to preferably say
The technical scheme of bright patent of the present invention, is not intended to be confined to shown details.Those skilled in the art is to of the invention
