When inserted into the second insertion hole 147, the needle 220 can be safely guided into the second insertion hole 147.

In forming the first insertion hole 144 and the second insertion hole 147, the first insertion hole 144 should be formed first and then the second insertion hole 147 should be formed. ), when the first insertion hole 144 is formed after first forming by drilling from the front of the inclined extension portion 145 of the second insertion hole 147, the rear end of the second insertion hole 147 and Between the front portion of the first insertion hole 144, a stepped portion 147-1 is generated in the direction in which the needle 220 enters, so that the rear end portion of the needle 220 is caught on the stepped portion 147-1. It is prevented from being inserted toward the insertion hole 144.

That is, in the case where the second insertion hole 147 is formed first, the rear end of the second insertion hole 147 allows the rear portion of the second insertion hole 147 and the front portion of the first insertion hole 144 to communicate with each other. The part should be formed in a deeper position past the front end of the first insertion hole 144, and when the first insertion hole 144 is formed thereafter, the second insertion hole 147 and the first insertion hole ( 144), a step 147-1 is generated in the direction in which the rear needle part 222 enters the contact area, so that the rear end of the rear needle part 222 is tied to the step 147-1, and the first It will not be continuously inserted toward the insertion hole 144.

Therefore, in order to solve this problem, as shown in FIG. After forming first, the rear end of the second insertion hole 147 is located behind the front end of the first insertion hole 144 and formed by drilling to form the second insertion hole 147 so that it communicates with the rear needle portion ( 222) so that the step is not formed in the direction in which the group enters, so that the rear needle portion 222 is smoothly exposed to the rear portion of the body 141.

Since the needle 220 has a diameter of about 0.2 to 0.3 mm and is made of SUS material, so it is relatively free to bend, the rear needle part 222 has an inclination angle between the second insertion hole 147 and the first insertion hole 144. It can be inserted while being bent by degrees.

In addition, since the inner diameters of the second insertion hole 147 and the first insertion hole 144 are formed larger than the diameter of the needle 220, when inserting the rear needle part 222, the first insertion hole 144 and the second insertion hole 144 It is possible to easily insert the two insertion holes 147 while bending along the inclination angle at the site where they meet each other.

The needle assembly 200 is divided into a front needle part 221 and a rear needle part 222 based on the body 210 by inserting the needle 220 through the center of the body 210 made of synthetic resin material. do.

An inner fastening part 211 is formed along the inner circumference of the rear part of the body 210 to be screwed to the front fastening part 146 of the needle assembly fastening part 140, and the rear needle part 222 ) Penetrates the sealing portion 310 of the ampoule 300 by protruding to the inside of the cylinder 110 through the second insertion hole 147 and the first insertion hole 144 of the needle assembly fastening portion 140 You will have the length you can.

Therefore, the locking handle and the plunger are fastened to the rear part of the cylinder 110, and the needle assembly 200 is connected to the needle assembly fastening part in a state where the needle assembly fastening part 140 is fastened to the front part of the cylinder 110. When fastened to the front part of 140, the rear needle part 222 is guided by the expansion part 148 and passes through the second insertion hole 147 and the first insertion hole 144 to the rear of the body 141. protrudes into the area.

Then, when the ampoule 300 is inserted through the ampoule insertion hole 111 and pushed toward the front of the cylinder 111, the sealing portion 310 of the ampoule 300 having elastic force because the rear needle portion 222 is made of rubber. While being inserted into the ampoule 300 through ), the sealing part 310 of the ampoule 300 comes into contact with the rear end of the support protrusion 143 while pressing.

The diameter of the support protrusion 144 is formed slightly smaller than the size of the sealing portion 310, so that when the ampoule 300 is initially slightly pressed by the plunger, the sealing portion ( 310 is in close contact with the rear end of the support protrusion 144, so that the support protrusion 144 presses the sealing part 310 into the ampoule 300.

Therefore, when the front needle part 221 is pierced into the area to be anesthetized and then pressing of the plunger is stopped, the sealing part 310 is restored by the elastic force and negative pressure is formed inside the ampoule 300, and the negative pressure causes the The aspiration operation as already described in is performed automatically.

Therefore, if blood does not flow into the ampoule 300, it is not a state in which the blood vessel is pierced, so the medical person rotates the plunger by the fixing handle and the pressure handle to pressurize the drug inside the ampoule 300 and the needle 220 ) through which the drug is injected.

At this time, since the needle front part 221 maintains the inclination angle, the medical person does not have to twist or break the wrist or arm, reducing fatigue and injecting the drug into the correct position of the body, as well as preventing unsafe posture. Musculoskeletal disorders can also be prevented.

In particular, in the case of block anesthesia of the patient's upper posterior teeth or lower jaw, buccal infiltration anesthesia, etc. during dental treatment, the drug can be injected while maintaining the needle 220 at a constant angle (15 °, 20 °, 30 °, etc.) This makes it much easier to inject the drug.

7 is a diagram showing another form of the needle assembly fastening part 140 of the present invention, in FIG. 3, the rear needle portion 222 is inserted into the first insertion hole 144 through the second insertion hole 147. 7 (a), the inner diameter is expanded from the rear end of the second insertion hole 147 to the front end of the inclined extension part 145, and the rear needle part 222 ) has a structure that penetrates in a straight line from the front end of the second insertion hole 147 to the rear end of the first insertion hole 144.

To this end, the front end of the lower end portion 147-1 of the second insertion hole 147 is located at the same height as the upper end portion of the first insertion hole 144 or is formed to be located below the rear needle portion 222 When ) is inserted into the first insertion hole 144 through the second insertion hole 147, it is inserted and penetrated in a straight line so that the medical personnel can relatively easily mount the rear needle portion 222.
