Description

Safety needle cover structure

The present invention relates to a needle cover structure, and more particularly to a safety needle cover structure assembled on a syringe needle.

Press, because the injection of the syringe is an invasive treatment, the needle needs to be inserted into the human skin, so that after the needle is used, the body fluid often remains on the needle or inside the needle; therefore, there are many The medical care or medical waste disposal personnel, due to the improper handling of the needle after the injection of the syringe, caused accidentally being stabbed by the needle of the syringe, and then infected with diseases such as AIDS, tuberculosis and other bloody infections.

In general, the needle barrel is provided with a needle cover at the needle, which not only protects the needle from damage or contamination before use, but also can be used to cover the needle after the syringe is used. Injury medical or medical waste disposal personnel to avoid infection of medical or medical waste disposal personnel.

However, when the medical staff needs to cover the used needle with the needle cover, the opening of the needle cover is small, so that the needle is not easily inserted into the needle cover, and the insertion angle is inaccurate or negligent. The deviation was not inserted into the correct position, causing accidental needle stick injuries, which led to potential exposure to infectious diseases.

In view of this, the creator has been engaged in the manufacturing development and design of related products for many years. Experience, after the detailed design and careful evaluation of the above objectives, will ultimately be a practical creation.

The technical problem to be solved by the present invention is to provide a safety needle cover structure in view of the above-mentioned shortcomings existing in the prior art.

A safety needle cover structure comprising: a needle cover body having a nest and a cover in an L shape, and a movable bending portion and a cover body are integrally connected to the rear end of the nesting seat The nesting system has a C-shaped opening, the inner side wall of the C-shaped opening is symmetrically provided with a horizontal recessed groove, and a blocking portion is protruded adjacent to the horizontal recessed groove at the C-shaped open end, the cover system The recess is provided with a receiving groove, and an opening is arranged in the bottom end corresponding to the nesting seat to communicate with the receiving groove. With the above structure, the weir is configured to form a safety needle cover structure.

Compared with the efficacy of the prior art: the main purpose of the creation is that after the needle injection is used, the needle can be directly bent through the needle cover body to provide the cover body to the needle direction to bend the needle to cover the needle conveniently and quickly. It can not only avoid the needle stick injury during the cover back cover process, but also ensure the safety of the medical or medical waste disposal personnel, and the utility model is more effective in its overall application.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please refer to the following [Simplified Description of the Drawings] for details: First, please refer to Figures 1 and 2 below. A safety needle cover structure comprising: a needle cover body 10 having a nesting seat 11 and a cover body 12 in an L shape, and a movable bending portion at the rear end of the nesting seat 11 13 is integrally connected with the cover body 12, wherein the nesting seat 11 is open and has a C-shaped opening 111. The inner side wall of the C-shaped opening 111 is symmetrically provided with a horizontal fitting groove 112, and is adjacent to the end of the C-shaped opening 111. The horizontal recessed portion 112 is provided with a blocking portion 113. The cover body 12 is recessed with a receiving groove 121, and an opening 122 is formed in the bottom end portion of the cover body 12 to communicate with the receiving groove 121. The accommodating groove 121 has an enlarged groove portion 123 extending inwardly from the opening 122, and a plurality of reinforcing ribs 124 are disposed on the inner wall of the accommodating groove 121, and at least one blocking piece 125 is extended. The movable bending portion 13 has a ridge. The hollow portion 131 is coupled to a V-shaped elastic plate body 132, and the above structure is used to complete a safety. Cap structure.

The state of the structure is actually used. Referring to the figures 2, 3, 4, and 5, the needle cover body 10 is matched with the needle 21 of the syringe 20, wherein the needle 21 has a circular shaft portion 211. The sleeve body 22 is provided with a sleeve positioning position, and the bottom end of the round shaft portion 211 has a limit stop 212. Thereby, when the needle cover body 10 is used in combination with the needle 21 of the syringe 20, the cover body is used. 12 is directed toward the syringe 20, and is disposed on the circular shaft portion 211 of the needle 21 through the C-shaped opening 111 of the nesting seat 11, and is pressed down to embed the C-shaped opening 111 into the limiting stopper 212, and is horizontally embedded. 112 card nested into the limit The dam 212 is positioned and restrained by the stopper 113 at the end of the C-shaped opening 111, thereby completing the mounting of the needle cover body 10.

In summary, when the injection operation of the injection is to be performed, as shown in Figs. 6 and 7, the shaft cover 22 is pulled out from the needle 21 and injected through the end of the needle 21, and after the injection is completed, The cover body 12 of the needle cover body 10 can be swung in the direction of the needle 21 through the movable bending portion 13 , and the cover body 12 can be rotated by the auxiliary thrust by the elastic plate body 132 to accommodate the groove 121 . The frame is wrapped around the needle 21, and at the same time, the stopper 125 is formed by the needle 21 to form a limit, and the opening 122 end of the cover 12 is folded against the nest 11, thereby the needle 21 is surely embedded in the receiving groove 121. Therefore, the shaft cover 22 does not need to be covered back to the needle 21, and the needle 21 is prevented from being stabbed by the needle 21 during the process of covering the shaft cover 22, and the safety needle cover is covered and covered to prevent medical care. Or the medical waste related personnel are stabbed by the needle 21 to improve the safety of the structure.

According to the structure of the above specific embodiment, the following benefits can be obtained: the main purpose of the present invention is that after the needle 21 is used for injection, the cymbal can directly provide the cover body 12 to the needle 21 through the movable bending portion 13 through the needle cover body 10. The pendulum bends to shield the needle conveniently and quickly, which not only avoids the stab wound of the needle 21 during the cover-back process of the shaft-type cover 22, but also ensures the safety of medical personnel or medical waste disposal personnel. And in the overall implementation of the use of more practical effects.

In summary, this creation has indeed achieved a breakthrough structural design, with improved creative content, while at the same time achieving industrial use and progress, and this creation has not been seen in any publication, but also novel, when In accordance with the provisions of the relevant laws and regulations of the Patent Law, the application for the creation of a patent shall be filed according to law, and the examination of the member of the Bureau shall be granted a legal patent right.

Only the above-mentioned ones are only preferred embodiments of the present invention, and the scope of the creation of the present invention cannot be limited thereto; that is, the equal changes and modifications made by the general applicants according to the scope of the patent application for the creation, All should remain within the scope of this creation patent.
