A syringe that suppresses decomposition of hydrogen peroxide is provided. An object of the present invention is to provide a syringe includes a portion contacting a hydrogen peroxide solution, in which the portion is made of cycloolefin polymer (COP) or cycloolefin copolymer (COC).

An insertion assembly and method of manufacturing an insertion assembly. The method includes forming a catheter assembly including a catheter hub and a catheter, inserting a needle into the catheter assembly such that a distal tip of the needle extends distal of a distal end of the catheter, and permanently adhering an interface pad to the catheter hub. The interface pad can include a foam material including a haemostatic agent. The haemostatic agent can include microdispersed oxidized cellulose. The foam material can further include an antimicrobial agent such as chlorhexidine gluconate.

An apparatus for use with a syringe to provide a safety syringe, the apparatus including: a sheath deployable for at least partially covering a needle of the syringe; a sheath actuator for deploying the sheath; and a ratioed mechanism linking the sheath and the sheath actuator and configured such that a magnitude of movement of the sheath is greater than a magnitude of movement of the sheath actuator during deployment of the sheath.

A cannula-catheter bonding method and apparatus can include a needle having a specifically configured connector end to reduce the risk of the connector end disengaging with an adapter (e.g., a catheter, a cannula, or a connector of a Huber needle assembly, etc.). The specifically configured needle connector end can be a formation, such as a barb, a bead, an annular structure, a rib, etc. The formation can be formed on the connector end, and may be elongated with a conical shaped nose leading to a base with a bottom. The formation can be used to prevent movement of the needle relative to the adapter. A method for producing the formation can include forming a mold for the formation in a plate, where the connector end can then be placed within the mold so that curable material can be disposed within the mold. Upon hardening of the curable material, the formation can take the shape of at least a portion of the mold.

A medical delivery device is provided for delivering a medicinal substance into a user's body. A foldable hub has a left wing and a right wing, where the hub is attached at one end to a tube, and at an opposite end to a needle. At least one first rib is disposed on the left wing and at least one second rib is disposed on the right wing. When the wings are folded back away from the needle and pinched together, the first and second ribs prevent twisting and/or sliding of the wings relative to each other during an insertion of the needle into a user's skin, thereby preventing a breakage of the needle due to undesirable movement of the wings.

A needle assembly to prevent fluid/vapor escape so as to reduce or prevent fluid exposure to a clinician during use of the needle assembly. The needle assembly may include a handle portion with a needle extending therefrom, and a base portion releasably coupled to the handle portion. The base portion may include a safety assembly to shield a distal tip of the needle and prevent user contact therewith. The base portion may further include a self-sealing pad covering a bottom external surface thereof. The self-sealing pad may include an upper surface designed to mate with the base portion and a raised portion compressively positioned in the opening of the bottom external surface. The needle assembly may further include a fluid isolation component.

A safety needle device is disclosed having a housing configured to couple to a syringe, the housing having a proximal end, a distal end, and a housing body. A needle hub is disposed on the proximal end of the housing and a needle cannula is attached to the needle hub. The device having a retractable sheath configured to move between an initial position, a retracted position and an extended position with respect to the housing, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula. The safety needle device may include an activation latch, a lockout latch, a tether and a spring element to bias the retractable sheath to an extended state to cover the distal end of the needle cannula upon completion of an injection. The safety needle device may include a slider element disposed above an activation latch. A method of drug delivery is also disclosed.

A needle assembly includes a needle and a needle shield device. The needle shield device includes an inner shield connectable to at least one a base and a fluid connector connectable to the base, and an outer shield fixedly connected to the opposing end the needle and displaceable relative to the inner shield between a first position, in which the sharpened end of the needle is exposed outside the inner shield, and a second position, in which the sharpened end of the needle is shielded by the inner shield. Interaction between portions of the inner and outer shields during or after proximal displacement of the outer shield from the first position to the second position automatically releases or permits release of the inner shield from connection to the at least one of the base and the fluid connector.

A safety needle device is disclosed having a housing configured to couple to a syringe, the housing having a proximal end, a distal end, and a housing body. A first guide path, a second guide path and a third guide path may be disposed on the housing body. A needle hub is disposed on the proximal end of the housing and a needle cannula is attached to the needle hub. The device having a retractable sheath configured to move between an initial position, a retracted position and an extended position with respect to the housing, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula. The retractable sheath also may have a guide element. The first, second and third guide paths are configured to slidingly receive the guide element. The device also having a first locking member, a second locking member, a rotating cam disposed in the housing body, and a spring element to bias the retractable sheath to an extended state to cover the distal end of the needle cannula upon completion of an injection.
