摘要:
A blood collection assembly includes a housing and a cannula extending distally from the housing including a patient end, and a cannula shield removably engaged with a portion of the housing. The cannula shield is capable of shielding at least the patient end of the cannula, and includes a safety shield engagement. The assembly includes a pivoting safety shield engaged with a portion of the housing, which is transitionable from a retracted position in which the patient end of the cannula is exposed, to an extended position in which the patient end of the cannula is shielded by at least a portion of the safety shield. The safety shield includes at least one locking tab releasably engageable with the safety shield engagement, wherein the locking tab is fixedly engageable with a portion of the housing in the extended position.

An automatically locking safety device, e.g., for use in a blood collection procedure, can include a housing, first and second needle covers that are at least partly received in the housing, and a needle that is at least partly received in at least one of the first and second needle covers. The needle can include a proximal tip configured for placement into a patient and a distal tip configured for placement into a blood collection vial. In some embodiments, the first and second needle covers are biased by a biasing member. In some cases, one or both of the first and second needle covers can be locked to prevent axial movement thereof after the blood collection procedure. In certain embodiments, a distal end of the device is configured to connect with a medical connector, such as a needleless IV access device.

A needle assembly includes a housing having proximal and distal ends, an IV cannula projecting distally from the housing, and an IV shield having an engagement. The housing has a shield seat and the IV cannula has a distal tip. The IV shield has a pre-use position where the IV shield covers the distal tip of the IV cannula and the engagement is disengaged from the shield seat, and a use position where the engagement is engaged with the shield seat and the IV shield is adapted to move between a non-shielded position, in which the distal tip is exposed, and a shielded position, in which the distal tip is shielded by the IV shield.

A safety syringe assembly and a replaceable base unit are disclosed. The replaceable base unit of the present invention includes a base portion, a needle cover and a disengagement actuator. The base portion is configured to detachably connect with a syringe holder and has a through-hole structure, which is used to connect with an external needle. The needle cover's proximal end is connected with the base portion to allow the needle cover to move with respect to the base portion, enabling it to contain and cover the syringe needle. The disengagement actuator is configured on the base portion and disengages the base portion from the syringe holder in pressing mode.

A needle assembly is disclosed. The needle assembly includes a housing having a flash chamber, and having a distal end and a proximal end engageable with a specimen collection container. The assembly includes a cannula having a patient end, a non-patient end, and a sidewall extending therebetween defining a cannula interior. The patient end of the cannula projects at least partially from the distal end of the housing, and the cannula interior is in fluid communication with the flash chamber. The assembly further includes a shield restrainably engaged with a portion of the housing and axially transitionable over the patient cannula from a retracted position in which the patient end is exposed, to an extended position in which the patient end is shielded by at least a portion of the shield, wherein at least a portion of the flash chamber is visible in the retracted position.

A housing has upper, lower, and central sections having a common axis and forming an interior chamber. An opening in the intermediate section has upper, lower, and sides edges. A flap has one edge coupled with the opening and covers the opening. A support is slidable between extended and retracted orientations. The support has central, upper, and lower extents. A cylindrical bore extends through the support. The support has legs, including a short leg, extending downwardly and outwardly and adapted to be radially contracted with the short leg within the opening restrained from downward movement. The flap is adapted to be depressed to move the short leg from contact with the opening and spring the legs outwardly to move the support from the extended orientation to the retracted orientation. Upper and lower needles extend from the upper and lower extents of the support for movement therewith.

A one piece molded vacuum tube holder is fitted with a one piece molded needle hub assembly. One portion of a locking mechanism is provided at the neck of the one piece vacuum tube holder and a second portion of the locking mechanism is provided at the needle hub of the needle hub assembly. The needle hub assembly is press fit to the vacuum tube holder. The one piece vacuum tube holder is configured to have an elongate needle cover integrally extending from its neck. A tamper evident notched joint is provided at the junction where the needle cover is connected to the neck. The opening of the vacuum tube holder through which a conventional vacuum tube is inserted may be sealed for sterilization and transport of the device. A wingnut finger grasp mechanism may be coupled to the needle cover.

Fluid collection/injection device comprises a body having a front end, a back end, and a main hollow section arranged between the front and back ends and a needle hub securing section arranged on the front end and being structured and arranged to receive therein a needle member. The fluid collection/injection device is structured and arranged to utilize at least an operational mode, an operational mode, and a post-use mode. In the installation mode, the needle member is coupled to the body via the needle hub securing section. In the operational mode, fluid passes through the needle member and into or out of a receptacle inserted into the main hollow section.
