Detailed Description
The following detailed description of the embodiments of the present invention will be provided in conjunction with the accompanying drawings to facilitate further understanding of the present invention by those skilled in the art, and should not be construed as limiting the scope of the present invention.
Example 1: referring to fig. 1, the anti-acupuncture safe dispensing needle comprises a needle base 10 and a needle body 2 fixed on the needle base 10, and further comprises a fixed sleeve 8 and a protective sleeve 1; the bottom of the fixed sleeve 8 is fixed on the needle seat 10, and the top of the fixed sleeve 8 and the protective sleeve 1 are respectively provided with a connecting mechanism for connecting the protective sleeve 1 with the fixed sleeve 8; the needle body 2 extends out of the top end of the fixing sleeve 8 through the inner cavity of the fixing sleeve 8 and extends into the protective sleeve 1, a needle body channel 11 for the needle body 2 to pass through is arranged in the protective sleeve 1, and a limiting disc 5 is fixedly arranged at the lower part of the protective sleeve 1; the needle body 2 in the inner cavity of the fixed sleeve 8 is sleeved with an elastic part 7, and two ends of the elastic part 7 are respectively limited by a limiting disc 5 and a needle seat 10. Under the state that the protective sleeve 1 is connected with the fixed sleeve 8 through the connecting mechanism, the part of the needle body 2 extending out of the top end of the fixed sleeve 8 is positioned in the protective sleeve 1; under the state that the protective sleeve 1 is disconnected with the fixed sleeve 8, the protective sleeve 1 slides towards the lower part of the fixed sleeve 8 under the action of external force, and the front end of the needle body 2 extends out of the protective sleeve 1 through the needle body channel 11.
The process of dispensing using this example was: before using, confirm that protective sheath 1 is connected through coupling mechanism with fixed cover 8, make the needle body 2 front end in protective sheath 1 to ensure that the nursing staff can't touch needle body 2. When in use, the needle base 10 is firstly connected with the injector, and then the protective sleeve 1 is disconnected with the fixed sleeve 8 so as to be capable of sliding. The needle body 2 is still not exposed due to the thrust of the elastic member 7. Then the dispensing needle is aligned with the bottle stopper to be punctured and the syringe shell is pushed. Under the action of the protective sleeve, the protective sleeve 1 gradually slides towards the lower part of the fixed sleeve 8, so that the front end of the needle body 2 extends out of the protective sleeve 1 through the needle body channel 11 to puncture the bottle stopper. After the extraction or injection action is finished, the needle body 2 is extracted from the bottle stopper. The protective sleeve 1 slides towards the upper part of the fixed sleeve 8 gradually under the thrust of the elastic part 7 until the needle body 2 is completely separated from the bottle stopper. After the use, the protective sleeve 1 and the fixed sleeve 8 are connected through the connecting mechanism again.
Example 2: referring to fig. 1, in the anti-needle-stick safety dispensing needle according to embodiment 1, the connecting mechanism is an internal thread and an external thread respectively arranged on the fixed sleeve 8 and the protective sleeve 1. Through the connection mode of internal and external screw threads, the quick connection and the release of the protective sleeve 1 and the fixed sleeve 8 can be realized, and the safety protection of the needle body 2 and the needle head thereof can be realized.
Example 3: referring to fig. 1, in the safety dispensing needle for preventing needle stick in embodiment 2, the internal thread 3 is arranged on the inner top of the fixing sleeve 8, and the external thread 4 is arranged on the outer wall of the protecting sleeve 1. Protective sheath 1 is connected through external screw thread 4 and internal thread 3 phase-matchs with fixed cover 8, establishes external screw thread 4 and is favorable to guaranteeing protective sheath 1's intensity on protective sheath 1's outer wall.
Example 4: in the anti-needle-stick safety dispensing needle according to embodiment 1, the connecting mechanisms are respectively a clamping groove and a clamping block arranged on the fixed sleeve 8 and the protective sleeve 1. This is another convenient way of connecting the protective sleeve 1 to the pouch 8. Through the mode, the quick connection and the release of the protective sleeve 1 and the fixed sleeve 8 can be realized, and the safety protection of the needle body 2 and the needle head thereof is realized.
Example 5: in the anti-needle-stick safety dispensing needle according to embodiment 4, the clamping groove is formed in the inner top of the fixing sleeve 8, and the clamping block is formed on the outer wall of the protective sleeve 1. Protective sheath 1 is connected through fixture block and draw-in groove phase-match with fixed cover 8, establishes the fixture block and is favorable to guaranteeing protective sheath 1's intensity on protective sheath 1's outer wall equally.
Example 6: referring to fig. 2, in the anti-acupuncture safety dispensing needle of embodiment 1, the bottom of the limiting disc 5 is provided with a protective sleeve limiting table 6, the top of the needle base 10 is provided with a needle base limiting table 9, and the protective sleeve 1 is matched with the needle base limiting table 9 through the protective sleeve limiting table 6 to realize the descending stroke limitation of the protective sleeve 1. In the process that the protective sleeve 1 slides towards the lower part of the fixed sleeve 8, when the protective rod limiting table 6 is contacted with the needle seat limiting table 9, the protective sleeve 1 reaches a descending limit position.
Example 7: referring to fig. 1, in the anti-acupuncture safety dispensing needle according to embodiment 6, the limiting disc 5, the protective sheath limiting table 6 and the needle seat limiting table 9 are circumferentially arranged.
Example 8: referring to fig. 1, in the safety dispensing needle for preventing needle stick according to embodiment 1, the elastic member 7 is a spring.
Example 9: referring to fig. 1, in the safety dispensing needle for preventing needle stick in embodiment 1, a 6% luer taper joint is adopted at the bottom of the needle base 10. The needle stand 10 is connected with the syringe through a 6% Ruhr conical joint.
