Abstract: 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 assembly 10 in which an inner needle unit 16 comprises a storage housing 14 for storing a protector 52, and which is provided with a connecting member 94 that connects the storage housing 14 to an outer needle hub 20. The protector 52 prevents movement of the connecting member 94 and holds the storage housing 14 and the outer needle hub 20 in a connected state. Deformation or displacement of the protector 52 due to retraction of an inner needle 12 permits the movement of the connecting member 94 and makes it possible to release the connected state between the storage housing 14 and the outer needle hub 20.

Abstract: A drug solution injection controller 10 includes a sub-reservoir 24 connected via a sub-line 26 to a main line 14 for performing continuous administration of a drug solution such that rapid administration of the drug solution from the sub-reservoir 24 by self-operation is enabled, and comprises: a priming flow path 46 configured to perform priming on at least one of the main line 14 and the sub-line 26; a closing mechanism 48 configured to close the priming flow path 46; and a connector holding part 84 holding a terminal connector 18 connected to the main line 14. Holding of the terminal connector 18 by the connector holding part 84 is allowed to be released due to operation of an operation switch 50 configured to activate the closing mechanism 48.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
