Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIGS. 1-5, the present utility model provides a technical solution: a needle tube for easy extraction, comprising a needle tube body 1, a control bayonet 2, a needle tube connector 3, a branch connector tube 4, a branch connector 5, and a sealing cap 6. Piston push rod 7, control ring 8, connection baffle 9, fixed connector 10 and piston 11, the upper end of the needle tube body 1 is fixedly provided with a control bayonet 2, and the lower end of the needle tube body 1 is fixedly provided with a needle tube connector 3 , and the outer side of the needle tube connector 3 is fixedly provided with a branch connection tube 4, the outer end of the branch connection tube 4 is fixedly provided with a branch connector 5, and the outer side of the branch connector 5 is installed and connected with a sealing cap 6, and the inside of the needle tube body 1 A piston push rod 7 is provided, and the upper end of the piston push rod 7 is fixedly provided with a control ring 8, the lower end of the piston push rod 7 is fixedly provided with a connecting block 9, and the lower side of the connecting block 9 is fixedly provided with a fixed connector 10. A piston 11 is connected and installed on the outer side of the fixed connector 10, and the piston 11 is located inside the needle tube body 1.

The needle tube body 1, the control bayonet 2, the needle tube connection head 3, the branch connection tube 4 and the branch connection head 5 are an integrated structure, which ensures the overall stable and safe use process of the needle tube and improves the use performance of the needle tube.

The control bayonet 2 is symmetrically arranged at the upper end of the needle tube body 1, and the inner side of the control bayonet 2 is a "U"-shaped opening, and the length of the upper side of the control bayonet 2 is greater than the length of the lower side of the control bayonet 2. It is convenient to operate the needle tube with one hand, and it can also facilitate the connection between the user's finger and the manipulation bayonet 2, thereby improving the use efficiency of the needle tube.

The branch connecting tube 4 is inclined on the needle tube connecting head 3, and the length of the branch connecting tube 4 is greater than the outer diameter of the needle tube main body 1, which can facilitate the connection between another syringe and the branch connecting tube 4, and also reduce the The connection of the other syringe to the branch connecting pipe 4 has a bad influence on the normal use of the needle pipe, which improves the use performance of the branch connecting pipe 4 .

The branch connector 5 and the sealing cap 6 are connected by a threaded seal, and the inner space of the branch connector 5 is a circular truncated hole, which can facilitate the connection of the branch connector 5 with syringes of different sizes, and improve the applicability of the branch connector 5. At the same time, it can also avoid the adverse effect of the opening of the branch connector 5 on the use of the needle tube, and ensure the normal use of the needle tube.

The piston push rod 7, the control ring 8, the connection baffle 9 and the fixed connection head 10 are all integrated structures, and the peripheral width of the piston push rod 7 is equal to the inner diameter of the needle tube body 1, ensuring that the piston push rod 7 is inside the needle tube body 1. The stable push-pull use state can ensure the normal use of the needle tube.

Working principle: When using the easy-to-extract needle, first, according to Figure 1-2, the liquid (such as hyaluronic acid) required for cosmetic injection needs to be extracted into the needle body 1. The operator can hold the needle body 1 and the needle with both hands. The control ring 8 on the piston push rod 7 can quickly complete the extraction of hyaluronic acid;

After the hyaluronic acid is extracted into the needle tube body 1, the cosmetic injection can be performed. First, the injection needle is installed on the needle tube connector 3 on the end of the needle tube body 1, and the injection needle on the needle tube connector 3 is inserted into the face of the cosmetic surgeon. In the skin, then, the needle needs to be withdrawn after it is inserted under the skin to ensure that it is not mistakenly entered into a blood vessel;

However, the hyaluronic acid existing inside the needle tube body 1 is similar to a semi-solid, so the push-pull movement of the piston push rod 7 on the needle tube body 1 is very inconvenient. The other syringe is connected to the branch connector 5 (as shown in Figure 3-4), and by pushing and pulling a syringe, it can be detected whether the injection needle on the needle tube connector 3 is inserted into the blood vessel by mistake after being subcutaneously inserted;

After the inspection work, according to Figure 1, Figure 2 and Figure 5, remove the syringe connected to the branch connector 5, and re-install the sealing cap 6 on the branch connector 5 to seal it to avoid affecting the subsequent hyaluronic acid. In the injection work, the operator finally holds the control bayonet 2 on the needle tube body 1 and the control ring 8 on the piston push rod 7, so that the piston 11 pushes the hyaluronic acid inside the needle tube body 1, and injects it into the subcutaneous through the injection needle;

The above completes the use process of the needle tube, and the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Within the spirit and principle of the present utility model, any modifications, equivalent replacements, improvements, etc. made shall be included within the protection scope of the present utility model.
