Description of the new model: [Technical field to which the new model belongs] This creation is about a syringe barrel and needle holder with a w 4 pin, which is stored in a syringe barrel, and is used after the use. The needle holder can retract the safety syringe. Application No. 09321 6670 β The design of this creative case is the same as the second creative design of the applicant. [Previous technology], a safe injection device not only helps patients, medical staff, and exams; the safety of the public has positive help. It not only involves injection tools and Z, but also reduces money. Non-safe injection behaviors such as county setting, use of needles or needle tubes, or incorrect technical operation = Some health institutions collect medical waste generated more, especially placing medical waste in anti-leak and anti-sharp Special bag for device penetration: Inside closed container. At the beginning of clothing: ¾ a safe injection device can enable medical services to perform nursing operations: the needle after use can be buried in a safe place to prevent stabbing medical staff when the oblique head is re-attached to the needle cover after use, Reduces the chance for medical staff to directly touch the needle after use. The shortcomings of the case finally succeeded. Therefore, in view of the above-mentioned safety injection device, the creator of this case was eager to improve and innovate. After painstaking research, he developed a syringe with a retractable needle base.

The shape of the lower plane 35 of the base 31 is round, and the base 31 is downward. A concave portion 36 is provided at the top of the concave portion, and one or more positioning portions 37 are formed at the convex portion. The needle base 3 is provided with a circular hole 38 penetrating the needle base 3, and the circular hole 38 is Can be fixed-needle 39, the needle 39 is connected with the circular hole 38 in the base 31, as shown in Figure 2 (D); a needle cover 4, is formed into a hollow cone shape for covering the For the benefit of the needle, the outer edge ring of the phase cover 4 is provided with a number of convex ribs 41, as shown in FIG. 7, and the needle can be in the form of the top and bottom ends communicating with each other or have only one opening. In the embodiment, the form in which the top end and the bottom end 14 communicate with each other is used as an example for illustration. Please refer to FIG. 5 and FIG. 5 (0, the needle base 3 is emptied by the base 31 through the round tube of the continuous syringe 1 Π, and the long wheel 341 2 8 M274961 on the flat surface 34 of the base 31 abuts against the lower edge of the annular convex portion 13 to form a catching state and is arranged in the accommodation portion of the injection loose ...

Therefore, when the user pulls out the push rod 2 (as shown in FIG. 7), the needle holder 3 can be detached from the receiving portion. It is stored in the circular tube space 11 of Note 1. See Figure 2 (A) for an enlarged illustration of the creation, and the needle holder 3 of this creation is also available. Other implementations are also provided, as shown in Figures 2 to 2 As shown in the figure, the positioning portion is placed on the top of the connecting portion 36, and one or a plurality of positioning portions 37 can be provided as required to enhance the binding force of the needle base 3 when it is separated from the receiving portion 15 of the syringe 1. , # In the syringe 1 of this creation, the accommodating portion 15 and the perforation 16 are connected to each other, and the aperture of the holly valley placing portion 15 is larger than the aperture of the perforation 16 ', thus forming a class with Shape, so when the base 31 is set in the injection cylinder i, it can completely correspond to the accommodating portion 15 and the perforation 16 and can be completely accommodated in the accommodating portion U, so that the needle base 3 cannot be removed from the perforation. The situation where the 16 drops out of the injections produces' the valley part 1 $ blood ip., 15 and 5 Hai perforated the class shape of the close-fit design of 16 can also avoid the leakage of the drug during injection. In addition, the The injection cylinder 1 is located at the abutting portion 12 provided at the abutment portion ，. The top of the disk injection Jing 1 is bundled to form a class. Therefore, when the retractable needle holder is used, note: when the device is used, the user When the pusher 2 is moved to the abutment portion 12,
