This creation is related to syringes, and in particular to a syringe with an engraved code.

According to the general market, the syringe is manufactured by using a mold to manufacture and manufacture, so as to achieve a large amount of manufacturing and cost saving. Since the syringe is used for applying the injection liquid to the human body, the specification of the finished product at the time of manufacture is required. It is very important to avoid problems such as liquid leakage or liquid discharge when the product is applied. When the mold is defective or damaged, it must be repaired immediately. Otherwise, it will lead to the production of a bunch of bad syringes, which will waste resources.

However, when such a conventional syringe is found to have defects during use, it is not known which mold is manufactured by the syringe, and only all the molds can be re-examined, which is extremely time consuming and affects production. Progress, there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and progressive syringe to solve the above problems.

The main purpose of the present invention is to provide a syringe which can quickly track which mold is manufactured by the syringe according to the code of the syringe when the syringe is defective or defective, to repair the mold. Or eliminated.

To achieve the above object, the present invention provides a syringe comprising a syringe, a needle set and a push rod. The syringe includes a converging section at one end of the syringe, the syringe enclosing a chamber. The needle set includes a adapter, a needle base and a needle. The adapter is detachably disposed in the converging section and is internally provided with a snap groove, and the needle base is connected to the adapter. The needle is disposed at the other end of the needle base away from the adapter. The outer wall of the adapter is provided with a code which is formed by the concave-convex structure in which the mold for forming the adapter is formed.

3 to 5 are schematic views showing the operation of a preferred embodiment of the present invention.

The structural features of the present invention and the intended effects thereof will be described below by way of a preferred embodiment, but are not intended to limit the scope of the present invention.

Referring to Figures 1 to 5, there is shown a preferred embodiment of the present invention. The syringe 1 of the present invention has a syringe 2, a needle set 3 and a push rod 4.

The syringe 2 includes a converging section 21 at one end of the syringe 2, the syringe 2 enclosing a chamber 22.

The needle set 3 includes a joint 31, a needle base 32 and a needle 33. The adapter 31 is detachably disposed in the converging section 21 and is internally provided with a snap groove 311. The needle base 32 is provided. The assembly is connected to the adapter 31. The needle 33 is disposed at the other end of the needle base 32 away from the adapter 31. The outer wall of the adapter 31 is provided with a code 34. The code 34 is formed by manufacturing. In the embodiment, the code 34 is a concave-grained structure, and in other embodiments, it may be a relief. In the embodiment, the needle base 32 is inserted into the adapter 31. The needle base 32 is provided with an externally threaded section 321 , and the adapter 31 is provided with an internal thread screwed to the externally threaded section 321 . In other embodiments, the needle base and the adapter may be in other combinations (such as a snap or a pressing manner).

The push rod 4 includes an elastic piston 41 and an ejector member 42. The elastic piston 41 is slidably disposed inside the syringe 2. The one end of the ejector member 42 is disposed on the elastic piston 41 and extends. The buckle portion 43.

In actual operation, when the push rod 4 slides toward the converging section 21 and the buckle portion 43 is inserted into the buckle groove 311, the buckle portion 43 is engaged with the buckle groove 311 to be injected. After the liquid is discharged for injection, the needle set 3 can be pulled into the syringe 2 through the ejector member 42. A protrusion 36 is disposed at one end of the push rod 31. When the buckle portion 43 is engaged with the buckle groove 311, the protrusion 36 of the adapter 31 can be pressed against the push. The elastic piston 41 of the rod 4 is coupled to bias the adapter 31 with the needle 33, so that the adapter 31 and the needle stay inside the syringe, so as to avoid accidentally pressing the push rod 4 toward the rod 4 When the converging section 21 slips, the needle 33 again passes out of the outside of the syringe 2 to cause a person to be stabbed. Therefore, the syringe 1 has a safety and sanitation effect, and the possibility of repeated use is eliminated.

Specifically, in the embodiment, the adapter 31 can further include a connected tubular section 312 and a tapered tapered section 313 which is gradually enlarged toward the push rod 4, and the straight section 312 is coupled to the needle base. The 32 phase is assembled, and the code 34 is disposed on the inclined cone section 313 to avoid affecting the straight section 312. The tightness with the converging section 21 causes the injection to leak.

Preferably, the outer wall of the adapter 31 is further provided with a first concave ring 314. The first concave ring 314 is located between the straight cylinder segment 312 and the oblique cone segment 313. The first concave ring 314 is sleeved. There is a sealing ring member 35. When the adapter 31 is located in the converging section 21, the sealing ring member 35 is sealed between the adapter 31 and the converging section 21 to prevent the injection solution from rotating. The gap between the joint 31 and the converging section 21 leaks. The inner wall of the converging section 21 can be further provided with a second recess 211. When the adapter 31 is located in the converging section 21, the sealing ring member 35 is engaged with the second recess 211. In order to prevent the adapter 31 from sliding freely within the converging section 21.

In detail, the code 34 is one of a numerical number, an English and a symbol, wherein each of the molds has a respective code. In the embodiment, the code 34 is a digital number, since the code 34 is provided in the adapter. 31, the user can conveniently see the code 34 through the outside of the syringe 2, and when the syringe 1 is finished, a part of the push rod 4 is usually broken and discarded, leaving only the elastic piston 41, the push top The piece 42 and the adapter 31 are in the syringe 2, such as when the syringe 1 is defective (such as liquid leakage or clogging), since each mold has its own code, the adapter can be used according to the adapter The code 34 of 31 quickly tracks which mold is manufactured by the mold 31 to repair or eliminate the mold, thereby avoiding repeated manufacture of defective products.

In addition, it is inevitable that a portion of the injection solution will remain in the syringe after the injection. In the present embodiment, the outer circumference of the elastic piston 41 extends in the direction of the adapter 31, and a protrusion 411 is additionally provided. When the push rod 4 slides toward the converging section 21 and the buckle portion 43 is inserted into the snap groove 311, the tenon 411 abuts against the inner surface of the elastic chamber 41 facing the chamber 22 And bending inwardly, wherein a center of the elastic piston 41 is disposed in a direction of the adapter 31, and a protrusion 412 is formed. The protrusion 411 has an extension length not less than a top of the protrusion 412, and the protrusion 411 faces toward the top of the protrusion 412. The inner bending can squeeze out part of the injection liquid remaining in the syringe 2.

In summary, in the syringe of the present invention, when the adapter is a defective product (such as liquid leakage or clogging), since each mold has its own code, it can be quickly learned according to the code of the adapter. Which adapter is manufactured by which the mold is repaired or eliminated to avoid repeated manufacture of defective products.

And, when the push rod slides toward the converging section and the snap portion is inserted into the snap groove, the tenon is bent inward against the inner surface of the elastic piston against the chamber surface, The tenon is bent inward to squeeze out part of the injection liquid remaining in the syringe.
