Specific embodiment
In fig. 1-3, the utility model relates to medical instruments fields, more specifically to a kind of novel integrated anti-needle
Stabbed syringe, comprising: syringe 1, syringe needle 2, adjustable diameter and screw adjusting cap 3, piston 4 and push rod 5 can effectively solve clinical use syringe
The caducous problem of syringe needle easily facilitates injection and use of making up a prescription；The inconsistent phenomenon during syringe needle time set is avoided, hair is reduced
A possibility that raw occupational exposure；Unitary design is more convenient for recycling, and effectively preventing may during syringe needle is recovered into sharp disposable container
The occupational exposure of generation；Keep operation more succinct convenient using spiral design, it is ensured that the high efficiency of clinical manipulation；It chooses normal
The polypropylene material of rule, and device does not influence syringe volume calculations, save the cost, use easy to produce.
In order to solve the above technical problems, piston 4 is fixedly connected with push rod 5；Piston 4 is slidably connected in syringe 1；Syringe needle 2
Lower end be slidably connected at the upper end of syringe 1；Adjustable diameter and screw adjusting cap 3 is threadedly coupled with syringe 1；The middle part of syringe needle 2 is threaded in
The inside of adjustable diameter and screw adjusting cap 3；
Piston 4 is slidably matched with the formation of syringe 1, medicament can be pushed into 2 part of syringe needle when piston 4 pushes；Cross connection
Head 2-1 is matched with cross limiting slot 1-1, so that syringe needle 2 is slidably connected on syringe 1；
Since external screw thread I is right-handed thread, external screw thread II is left hand thread, so adjustable diameter and screw adjusting cap 3 is inverse relative to syringe 1
When being revolved on hour hands, it will drive syringe needle 2 and moved up in the vertical direction relative to adjustable diameter and screw adjusting cap 3, so that dispensing end 2-4 stretches out
To the outside of adjustable diameter and screw adjusting cap 3；Similarly, when adjustable diameter and screw adjusting cap 3 is relative to 1 hour hands backspin clockwise of syringe, it will drive syringe needle 2 and exist
It is moved down vertical direction relative to adjustable diameter and screw adjusting cap 3, so that dispensing end 2-4 is retracted to the inside of adjustable diameter and screw adjusting cap 3；
During screwing out and screwing in dispensing end 2-4, when syringe needle 2 rises to top, dispensing end 2-4 is fully extended
To adjustable diameter and screw adjusting cap 3, baffle 3-1 can play position-limiting action, prevent syringe needle 2 from rising without limitation and being detached from syringe 1；Work as syringe needle
2 when dropping to lowermost end, and dispensing end 2-4 is fully retracted to adjustable diameter and screw adjusting cap 3, avoids medical staff by dispensing end with this
2-4 is stabbed, while limited block 2-3 can play position-limiting action, is prevented syringe needle 2 from declining without limitation, is called in syringe 1；Baffle 3-1's
Center is provided with through-hole, and the internal screw thread of the through-hole is matched with external screw thread II2-5, so that syringe needle 2 and 3 screw thread of adjustable diameter and screw adjusting cap connect
It connects；It is equipped with internal screw thread with the junction of syringe 1 on adjustable diameter and screw adjusting cap 3, which matches with external screw thread I1-2, so that spiral
Adjustment cap 3 is threadedly coupled with syringe 1；
The thread turns of the external screw thread I1-2 is greater than the thread turns of external screw thread II2-5, so that rising to most in syringe needle 2
When top, adjustable diameter and screw adjusting cap 3 is unlikely to fall off from syringe 1；
Cross opening silica gel thin film is equipped at the limit hole 3-2, as the channel of dispensing end 2-4 disengaging, while really
It protects before dispensing end 2-4 back-out and is not exposed in air, it is soft using silica gel matter, be unlikely to deform and feature that colorless and odorless is nontoxic,
Cross opening silica gel thin film is covered in the surface limit hole 3-2, avoids damage to syringe needle while reducing pollution；
The length of the cross connector 2-1 in the vertical direction is greater than the length of cross limiting slot 1-1, syringe 1
It is fixedly installed cross rubber gasket at inner upper end and syringe needle 2, so that movement of the cross connector 2-1 in syringe needle 2
It is interference fitted always with cross rubber gasket in the process, the utility model leakproofness can be reinforced, prevent the medicine in syringe 1
Liquid exudation；
The syringe 1, cross connector 2-1, engagement sleeves 2-2, limited block 2-3, adjustable diameter and screw adjusting cap 3 and push rod 5 are adopted
It is made of conventional polypropylene material, does not influence syringe volume calculations and obtain simultaneously, save the cost, use easy to produce.
The utility model is when in use:
Medical worker can be held by syringe 1 with one, and another hand rotates adjustable diameter and screw adjusting cap 3 counterclockwise, adjustable diameter and screw adjusting cap 3
While rotating counterclockwise the drive rising of syringe needle 2, syringe needle 2 is moved up relative to adjustable diameter and screw adjusting cap 3, until syringe needle 2 rises to
Top, until dispensing end 2-4 being screwed out completely outside adjustable diameter and screw adjusting cap 3；Then syringe sucking medical fluid is held；It is complete in medical worker
After the injection of pairs of patient, adjustable diameter and screw adjusting cap 3 can be rotated clockwise, rotating clockwise for adjustable diameter and screw adjusting cap 3 drives under syringe needle 2
While drop, syringe needle 2 is moved down relative to adjustable diameter and screw adjusting cap 3, until syringe needle 2 drops to lowermost end, dispensing end 2-4 is complete
Until screwing in adjustable diameter and screw adjusting cap 3；Used syringe can be directly placed into sharp disposable container by last medical worker.
Certain above description is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The variations, modifications, additions or substitutions that the those of ordinary skill in art field is made in the essential scope of the utility model, also belong to
In the protection scope of the utility model.
