Preferably, the surface of the injection cylinder is marked with a scale.

Preferably, the needle seat is in threaded connection with the first injection needle, the first injection needle is of a replaceable and detachable structure, and the first injection needle can be replaced by the second injection needle.

Preferably, the diameter of the rotary connector is smaller than the inner diameter of the first spiral protrusion.

Preferably, the second spiral protrusion is matched with the inner wall of the injection cylinder in size, and the second spiral protrusion is matched with the first spiral protrusion.

Preferably, the annular groove and the annular protrusion are the same in size and are matched with each other.

Compared with the prior art, the beneficial effects of the utility model are that: this syringe that anesthesia was used, the inside at present anesthetic syringe injection tube has add spiral protrusion one, the lower extreme of piston rod is provided with can pivoted swivelling joint spare and with spiral protrusion one assorted spiral protrusion two, make medical personnel when pulling the pull head, under piston rod and pull head can guarantee the circumstances of not rotating, swivelling joint spare and spiral protrusion two can rotate around the piston rod, and upwards or the downstream along spiral protrusion one, at this moment when drawing the anesthetic or injecting the anesthetic, can measure with a small amount of accuracy volume.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides an injector that anesthesia was used, including injection tube 1, fixedly connected with spiral protrusion 2 on 1's of injection tube the inner wall, 1's of injection tube upper end fixedly connected with backup pad 3, 1's of injection tube lower extreme fixedly connected with

needle file

4, 4's of needle file lower extreme swing joint has syringe needle one 5 or syringe needle two 501, 1's of injection tube inside swing joint has swivel connected coupler 6, fixedly connected with spiral protrusion two 7 on swivel connected coupler 6's the outer wall, annular groove 8 has been seted up on swivel connected coupler 6's the inner wall, swing joint has piston rod 9 on swivel connected coupler 6's the inner wall, fixedly connected with annular protrusion 10 on piston rod 9's the outer wall, the upper end fixedly connected with.

Furthermore, the surface of the injection tube 1 is marked with a dial gauge, which is beneficial for medical staff to accurately know the dosage of the injection anesthetic.

Furthermore, the needle seat 4 is in threaded connection with the first injection needle 5, the first injection needle 5 is of a replaceable dismounting structure, and the first injection needle 5 is replaceable with the second injection needle 501, so that the first injection needle 5 can be replaced with the second injection needle 501 for anesthesia injection when the first straight injection needle 5 is inconvenient to use for anesthesia injection.

Furthermore, the diameter of the rotary connecting piece 6 is smaller than the inner diameter of the first spiral protrusion 2, so that the rotary connecting piece 6 can move up and down in the injection cylinder 1 without being influenced by the first spiral protrusion 2.

Further, the size of the inner wall of the second spiral protrusion 7 and the inner wall of the injection tube 1 are matched, and the second spiral protrusion 7 and the first spiral protrusion 2 are matched, so that the second spiral protrusion 7 can rotate on the first spiral protrusion 2, and the second spiral protrusion 7 can move up and down.

Further, the annular groove 8 and the annular protrusion 10 are of the same size and are adapted to facilitate the rotation of the rotary joint member 6 around the piston rod 9.

The working principle is as follows: firstly, a certain amount of anesthetic is sucked in the anesthetic bottle by the injection needle I5, the anesthetic bottle abuts against the supporting plate 3, the push head 11 is pulled, the spiral protrusion II 7 on the rotary connecting piece 6 moves upwards around the spiral protrusion I2, the rotary connecting piece 6 rotates around the annular protrusion 10, when a certain amount of anesthetic is sucked, the push head 11 is pushed downwards, at the moment, the spiral protrusion II 7 rotates downwards along the track of the spiral protrusion I2, the rotary connecting piece 6 rotates around the annular protrusion 10 and slowly descends, and a certain amount of anesthetic is injected according to the scale on the injection tube 1.
