Abstract

The invention relates to the technical field of medical instruments, in particular to an automatic trigger type needle protection device and insulin pen needle. The automatic trigger type needle protection device at least comprises a needle base, a protecting bush, a protecting cover, a spring and a supporting piece, wherein the supporting piece at least comprises an initial state and a supportingstate and is configured to be capable of being switched from the initial state to the supporting state, and in the initial state, a supporting base body of the supporting piece is in contact with theupper end of the needle base and a circumference limiting mechanism is arranged between the supporting base body and a needle body mounting part, and in a supporting state, the supporting piece is disengaged from the sliding chute and the lower end of a supporting arm is located above a supporting surface. In the structure, the protecting cover is automatically triggered, secondary operation is avoided in the protection process, and the operation is simple and convenient; and the supporting piece is located at the inner side and supported in a space between the protecting cover and the needlebase in an axial direction, the security and the reliability of the supporting are better, and the needle protection state cannot be easily damaged from the external, and the secondary use of the insulin pen needle is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic trigger needle protection device and an insulin pen needle. Background technique [0002] In the prior art, there are many structure types of needle protection devices for insulin pen needles, mainly including manual protection type and automatic protection type. Among them, the insulin pen needle of the manual protection type needs to be manually pushed to the protective position after the injection is completed, which is inconvenient to operate. [0003] In the existing auto-protection type insulin pen needle, the needle shield will be triggered during the injection, so that after the injection is completed, the needle shield will automatically cover the injection needle. At present, the trigger mechanism of this type of automatic protection is usually realized through the cooperation of the track groove and the protrusion between the needle shield and the...
