A valved needle assembly includes a connector having an inner hole, a pipe body fixed to a tip end of the connector, a valve body, and an assembly part in which an insertion part provided to one of the connector and the pipe body is inserted into another such that the connector is disposed within or about the pipe body. A locking protrusion and a locking part are provided to superposed faces of the connector and the pipe body in the assembly part for preventing the insertion part from dislodgment by mutual lock, and an inclined guide surface for guiding the locking protrusion is formed on a tip end in a direction of assembly of the connector or the pipe body to which the locking part is provided. The valve body is incorporated by being mated with the connector and the pipe body.

Valved needle assembly and indwelling needle assembly

A novel hemostasis valve-equipped indwelling needle that is capable of discharging air in an internal flow path includes a cannula to be inserted percutaneously into a blood vessel on a distal end side thereof, a link connector on a proximal end side thereof, an internal flow path extending from the cannula to the link connector, and a hemostatic valve disposed inside the link connector. An air vent passage that allows the internal flow path to communicate with an external space is formed in the link connector further on the cannula side than the hemostatic valve, and a filter that allows gas to pass through but does not allow liquid to pass through is mounted in a compressed state on the air vent passage.

Hemostasis valve-equipped indwelling needle and indwelling needle assembly

An objective of the present invention is to provide an indwelling needle assembly that has a novel structure and improves operability for the practitioner. An indwelling needle assemblyin which an inner needle unitcomprises a storage housingfor storing a protector, and which is provided with a connecting memberthat connects the storage housingto an outer needle hub. The protectorprevents movement of the connecting memberand holds the storage housingand the outer needle hubin a connected state. Deformation or displacement of the protectordue to retraction of an inner needlepermits the movement of the connecting memberand makes it possible to release the connected state between the storage housingand the outer needle hub

Indwelling needle assembly

A hub assembly with a hub body connected to a tube from an external appliance, a hub outer casing which is coupled to the hub body and forms a liquid passage, a slitted separating wall disposed in the liquid passage in the hub outer casing, a filter disposed on the living body-side of the separating wall to allow the passage of gas and regulate the passage of liquid, and a ventilation passage which communicates between the liquid passage and the outside of the hub outer casing by way of the filter, wherein an end portion of the ventilation passage on the separating wall side of an opening portion facing the liquid passage is in a location at most 10 mm toward the distal end side relative to the distal end of the separating wall.

Hub assembly

A valved needle assembly including a needle hub provided to a proximal end side of a hollow needle, and a valve member incorporated therein for blocking communication with the hollow needle. A protrusion protrudes from a distal end side toward a proximal end side inside the needle hub and the valve member blocks the proximal end side of the protrusion inside the needle hub. A central valve part of the valve member having a slit moves toward the protrusion such that the slit is opened and placed in communication by the protrusion. The central valve part includes a distal end tubular part and a proximal end tubular part extending from its outer circumferential portion toward the distal end side and the proximal end side respectively.

Valved needle assembly

This needle assembly is provided with a needle having a needle tip, a needle hub, and a protector. The protector is displaceable between a non-protection position at which the needle is exposed and a protection position at which the needle tip is covered; has an opening formed elongated to match the needle, and includes a main body and a claw-like portion. The needle enters the main body from the opening to cover the needle tip when the protector is displaced to the protection position. The claw-like portion is bent by the needle when the protector is displaced to the protection position, allows the needle to advance into the main body, and is elastically restored to lock the needle when the needle enters the main body. The claw-like portion projects obliquely from the main body, extends across the opening in the width direction, and extends in the longitudinal direction.

Needle assembly and needle device having same

A medical valve which is able to more reliably support an outer peripheral part of an elastic valve body with respect to a housing, and prevent a problem of the elastic valve body becoming dislodged inward. A medical valve includes an elastic valve body with annular grooves formed thereon and a tubular support part formed at an outer peripheral side of an annular joining part positioned between the annular grooves. Inside and outside holding parts engage the annular grooves provided to the valve inside and outside surfaces of the annular joining part. The outside holding part and inside holding part are provided to an opening member, and with the tubular support part, a part projecting inward in an axial direction is sandwiched and supported between the inside holding part and outside holding part.

Medical valve

In an indwelling needle assembly, a safety mechanism part is provided with an outer-needle-hub engaging part to be engaged with an outer needle hub, and an engaging-part opposing wall. Relative rotation of the outer-needle-hub engaging part and the engaging-part opposing wall is restricted, and at least one of the outer-needle-hub engaging part and the engaging-part opposing wall displaces integrally with urging parts. When an inner needle is pulled out of the outer needle hub, a block part engaged with the inner needle through an inner-needle engaging part is moved relative to the urging parts and forced to a non-contact state, and the urging parts displace in a direction approaching the inner needle, thereby preventing a needle tip of the inner needle from protruding from the safety mechanism part and releasing engagement of the outer needle hub with the safety mechanism part.

A package has a rectangular parallelepiped container including vertical front and rear panel sections connected by a pair of vertical side panel sections, a top wall connected to the upper edge of the rear panel section and a bottom wall connected to the at least one of the lower edges of the vertical panels and a top cushion panel disposed beneath the top wall and rotatably connected to at least one upper edge of the side panel sections. A holder is disposed, in the container, for holding a plurality of glass syringes each of which is sealingly contained in a plastic bag.
