STAB-PREVENTING INJECTION NEEDLE AND STAB-PREVENTING INJECTOR WITH ELASTIC PROTECTIVE CAP
20220203044 · 2022-06-30 ·

A stab-resistant syringe needle with an elastic protective cap and a stab-resistant syringe are provided, which include the elastic protective cap. After the syringe is used to complete injection, the protective cap can be automatically ejected through simple operations to shield a steel needle, so as to achieve a purpose of preventing stab wounds.

Autoinjector

An autoinjector includes a case adapted to hold a medicament container, a needle shroud telescopically coupled to the case, and a plunger slidably disposed in the case. The needle shroud is movable between a first extended position, a retracted position, and a second extended position relative to the case. The plunger is movable between a proximal position, an intermediate position, and a distal position relative to the case. When the plunger is in the intermediate position and the needle shroud is in the retracted position, the plunger abuts the case to prevent the needle shroud from returning to the extended position. When the plunger is in the distal position and the needle shroud is in the second extended position, the plunger abuts the case to prevent the needle shroud from returning to the retracted position.

Auto-Injector

Auto-injector for administering a dose of a liquid medicament includes a housing to contain a syringe with a hollow needle and a stopper for sealing the syringe and displacing the medicament, the housing having a distal end and a proximal end with an orifice to apply against an injection site. A spring means, upon activation, can push the needle from inside the housing through the orifice and past the proximal end, operate the syringe to supply the dose of medicament, and retract the syringe with the needle after delivering the medicament. An activating means can lock the spring means in a pressurized state prior to manual operation and capable of, upon manual operation, releasing the spring means for injection.

Drug delivery system and method of use

A drug delivery system is disclosed that includes a drug delivery device having a reservoir and a delivery cannula having a proximal end in fluid communication with the reservoir and a distal end to be received within a patient. The drug delivery system may further include one or more sensors coupled to the drug delivery device, a wireless transmitter, and a controller coupled to the one or more sensors and the wireless transmitter. The controller may be configured to use the one or more sensors to determine a condition or an operational state of the drug delivery device, and control the wireless transmitter to wirelessly transmit one or more reports representative of the condition or the operational state of the drug delivery device. A method for use with a drug delivery device is also disclosed.

Active self-locking type syringe

An active self-locking type syringe includes a barrel, needle hub, plunger assembly, plunger protection cover, needle cap, needle tube, needle point protection sleeve, spring, guiding limit assemblies, initial clamping assemblies and a trigger ring plug. In an initial state, the trigger ring plug is located in a trigger cavity and is not in contact with the trigger parts or is in contact with the trigger parts but not enough to separate the initial clamping assemblies, the inner wall of the trigger ring plug and the needle hub are sealed, and the outer wall of the trigger ring plug and the inner wall of the barrel are sealed. In the above structure, the trigger ring plug arranged in the trigger cavity is triggered from the interior of the barrel close to a patient end, and the needle point protection sleeve is released.

MEDICAMENT DELIVERY DEVICE
20220152307 · 2022-05-19 ·

A medicament delivery device is disclosed having a housing, an actuation mechanism capable of delivering doses of medicament from a medicament container and arranged with a delivery member, a shield, a guard movable within the housing, wherein the guard is operably connected to the actuation mechanism. A protective cap is releasably arranged on the housing and having a shield remover. A blocking element on the guard is movable between a blocking position and a release position and has an engagement surface to engage a proximal area of the housing. The blocking element engages with a surface of the shield remover to retain the blocking element in the blocking position. The engagement surface causes a blocking of the guard from movement and removal of the protective cap enables a movement of the blocking element to a release position when the engagement surface engages the proximal area allowing the member guard to move.

Cap for an injector

Provided is a cap for an injector comprising a syringe with a needle cover. The cap comprises a cap body defining an inner and outer cap body; provided to the inner cap body, a grip for gripping the needle cover of said syringe; provided to the outer cap body, an opposing pair of recessed portions, wherein each recessed portion defines a recess base, and wherein each recessed portion is bounded by a peripheral lip; and provided to the recess base of each recessed portion, an over-coating. The cap body comprises a generally rigid material and each over-coating comprises a more flexible material. Each peripheral lip defines banks that extend beyond the over-coating of the recess base.

Syringe with locking mechanism

A syringe including an injection syringe body and a syringe handle, configured to cooperate with one another in order to ensure a locking function between the injection syringe body and the syringe handle. The injection syringe body includes a longitudinal hub including at least one female or male retaining element, and a protective sheath moveable along said longitudinal hub and able to cover in a retracted position the at least one retaining element of the longitudinal hub. The syringe handle includes at least one male or female retaining element intended to cooperate with the at least one female or male retaining element of the longitudinal hub, ensuring a retaining function, the cooperation being named locking position. The syringe further includes at least one blocker, the at least one blocker ensuring a radial holding function when the retracted and the locking positions are both engaged.

Safety pen needles

A safety pen needle includes: a main body, a cannula fixed to the main body and at least partially projecting out of the main body, a lock element placed inside the main body, a thrust element placed inside the main body, and a shield movable relative to the main body while remaining at least partially inserted within the main body. The pen needle is configured to move from a first configuration, in which the shield entirely covers an upper end of the cannula, to a second configuration, in which the upper end of the cannula is exposed, due to the action of external thrust. The pen needle is configured to move from the second configuration to an irreversible third configuration, in which the shield entirely covers the upper end of the cannula, due to the action of thrust exerted by the thrust element.
