Description
Technical field
The invention belongs to medical surgery equipment technology fields, and in particular to a kind of syringe accessory device.
Background technique
Syringe is a kind of common medical instruments.Early in the 15th century, Italian's Ka Di Nellie just proposes syringe
Principle.Gas or liquid are mainly extracted or injected with syringe needle.
Syringe mainly includes needle tubing, syringe needle and piston rod.When in use, by mobile piston rod to make to produce in needle tubing
Raw pressure change realizes the extraction or injection of medical fluid.However syringe is since specification difference causes outer dimension also different,
Therefore leading to the syringe of some specifications, there are bad usage experiences.In order to solve this problem, people have invented filling gun,
It is similar to " pistol ", thus has preferable usage experience, and this kind of syringe equally realizes note in such a way that piston rod is mobile
It penetrates and drawing liquid.But the operation power of current filling gun, from internal electro-mechanical device, this results in this kind of syringe
Structure it is complex and need to charge, and cost is higher, is only applicable to the treatment of some special diseases.And for one
For a little reusable filling guns, also it is unfavorable for sterilizing and safeguarding since structure is complicated.
In conclusion filling gun is not able to satisfy all injection work still.
Summary of the invention
It is an object of the invention to overcome deficiency in the prior art, the present invention proposes a kind of syringe accessory device, energy

Loaded on horizontal axis, horizontal axis is removably installed in accommodating chamber, and rack gear is slidably mounted in sliding slot and is meshed with gear；Rack gear
Top be provided with push plate, the front top of horizontal supporting part is provided with the fixed structure for being capable of fixing syringe；Push plate can
The piston rod of syringe is pushed with rack gear movement；Reset spring is connected between cursor and handle portion.
Preferably, fixed structure includes the fixed part that can be inserted into for syringe and is threaded into fixed part
Inner hole in fix the clamping screw of syringe.
It preferably, further include adjusting bolt, fixed frame and connecting tube；Fixed frame is slidably mounted by guide rod
In the front end of horizontal supporting part, adjusts bolt and be threadedly coupled across fixed frame with the formation of horizontal supporting part；Have on fixed frame and uses
It is connected by connecting tube with syringe needle in the needle tubing of the collet of the syringe needle of fixed syringe, syringe.
Preferably, horizontal supporting part has pilot hole and threaded hole, and guide rod is slidably matched with pilot hole formation, adjusts
Section bolt is threadedly coupled with threaded hole formation.
Preferably, the trailing flank of handle portion is the curved surface with striated structure.
The invention has the benefit that changing the operating method of transmission syringe by unchangable traditions syringe, making
It has usage experience identical with filling gun, and clever structure may be reused, and is easy to sterilized maintenance.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of syringe accessory device, including device noumenon, further include cursor 3, unilateral bearing,
Gear 6, rack gear 7 and reset spring 4；
There is device noumenon a horizontal supporting part 1 and one to be connected to the handle portion 2 of horizontal 1 lower section of supporting part；Horizontal support
The accommodating chamber 19 that there is a horizontal sliding slot 11 to be connected to sliding slot 11 with one in portion 1；The top of cursor 3 has a horizontal axis 5, gear 6
It is installed on horizontal axis 5 by unilateral bearing, horizontal axis 5 is removably installed in accommodating chamber 19, and rack gear 7 is slidably mounted on sliding slot 11
In and be meshed with gear 6；The top of rack gear 7 is provided with push plate 12, and the front top of horizontal supporting part 1, which is provided with, to be capable of fixing
The fixed structure of syringe；Push plate 12 can push the piston rod 21 of syringe with the movement of rack gear 7；Cursor 3 and handle portion 2
Between connect reset spring 4.
Fixed structure include can for syringe be inserted into fixed part 8 and be threaded into the inner hole of fixed part 8 with
The clamping screw 9 of fixed syringe.
Horizontal supporting part 1 has pilot hole 17 and threaded hole 18, and guide rod 15 is slidably matched with the formation of pilot hole 17, adjusts spiral shell
Bolt 14 is threadedly coupled with the formation of threaded hole 18.The axis of pilot hole 17 and the axis of threaded hole 18 are parallel to each other, and with sliding slot 11
In parallel.
Preferably, the trailing flank of handle portion 2 is the curved surface with striated structure.
When the present embodiment is in use, syringe assembling is first finished and has been extracted medical fluid, be then subsequently secured to horizontal support
In portion 1.Then adjusting push plate 12 again makes it withstand piston rod 21.Then the horizontal axis 5 of 3 upper end of cursor is installed to accommodating chamber 19
Interior, palm resists handle portion 2 at this time and pressing with finger cursor 3 moves forward rack gear 7.Since gear 6 can only unidirectionally turn
It is dynamic, therefore as being constantly pressed for cursor 3 moves forward push plate 12 persistently and push piston rod 21 is mobile to complete injection
Operation.
Embodiment 2
As shown in figure 3, compared with Example 1, the present embodiment further includes adjusting bolt 14, fixed frame 13 and connecting tube 16；
Fixed frame 13 is slidably mounted on the front end of horizontal supporting part 1 by guide rod 15, adjusts bolt 14 and passes through fixed frame 13 and water
Flat supporting part 1, which is formed, to be threadedly coupled；There is the collet for fixing the syringe needle 20 of syringe, the needle tubing of syringe on fixed frame 13
10 are connected by connecting tube 16 with syringe needle 20.
The present embodiment can satisfy the operation requirement of the syringe of other specifications, and if syringe size is smaller, syringe needle 20 is not
It can be completely out of the front end of horizontal supporting part 1, need to extract fixed frame 13 at this time, then be adjusted to close by adjusting bolt 14
Right position is set, and is then individually fixed on syringe needle 20 on collet, is then connect by connecting tube 16 with needle tubing 10.Subsequent operation and reality
It is identical to apply example 1, therefore does not repeat.
The present invention changes traditional injection operation mode by combining with syringe, and without electric power and only with
It can be completed manually, cost is lower, the syringe easy to use for being applicable to different size.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
