Abstract: A safety protective needle cover for butterfly needle assembly is disclosed. After the covering member is pivoted toward the base, the base may be covered by an accommodating space defined by the backs of the two pivoting walls and the concave cover such that the covering member and the base are parallel with each other. The needle will not be shifted due to the shake of the patient or being hooked by dress. After the covering member is pivoted toward the vertical portion of the L-shaped needle, the vertical portion of the L-shaped needle may be covered by the concave cover to prevent nursing staff or users from being stuck.

Abstract: By disabling at least one data transmission port of a media access device when the media access device is connected to a storage medium under an encrypted state and when the media access device is capable of performing decryption corresponding to an encryption mechanism applied on the storage medium, data security of the storage medium can be secured.

Abstract: A syringe includes a needle, a barrel and a push rod inserted in the barrel. The needle includes a needle seat, a stop ring fitted on an outer wall of the needle seat, and a check groove formed on the inner wall of the needle seat. The check groove is adapted to engage with a check rib on a core post of the push rod. A resilient plug is provided in the barrel. The resilient plug has a central through hole for insertion of the core post of a push head of the push rod. The push rod has a frangible point at a front end thereof. When the push rod is pulled backward, the needle is received in the barrel completely and the rear section of the push rod can be broken.

Abstract: An improved structure safety syringe comprised of a barrel having two trapezoidal-shaped tabs, a sleeve with a guide slot and, furthermore, limit slots extending from the circumferential surface at the two ends of the guide slot and an insertion section is formed at the inside end of the limit slot, wherein utilizing the engagement of the tabs and the insertion section enables the positioning of the barrel and the sleeve, and a plunger having a protective cap at the force application end that can be broken off at an appropriate time. When the protective cap is broken off and, furthermore, inserted into the other end of the sleeve, the objective of positioning is achieved and, furthermore, ensures that the hypodermic needle is not exposed.
