Needle module for a drive-controlled apparatus for repeatedly piercing human or animal skin, and handheld unit
A needle module for a drive-controlled handheld unit for repeatedly piercing human or animal skin, comprising a housing; a needle holder, which can be moved back and forth in the housing in a longitudinal direction of the housing; a piercing device on the needle holder, which can be moved, on account of the movement of the needle holder, between a proximal and a distal position, in which a piercing tip of the piercing device is arranged outside the housing; a coupling component, which is coupled to the needle holder in such a way that a driving movement provided with a repetition frequency by a drive device that can be coupled to the coupling component can be introduced onto the needle holder; and a damping component, which is arranged between the needle holder and the coupling component and is configured to damp a transfer of force therebetween.
System and method for safety syringe
A system for injecting includes a syringe body defining a proximal opening and a distal needle interface. The system also includes a plunger member defining a plunger interior and configured to be manually manipulated to insert a stopper member relative to the syringe body. The plunger member includes a needle retention feature disposed in the plunger interior, an energy-storage member disposed in the plunger interior, and an energy-storage member latching member disposed in the plunger interior. The system further includes a needle hub assembly coupled to the distal needle interface of the syringe body. The needle assembly includes a needle having a needle proximal end feature, a hub, and a needle latching member configured to couple the needle to the hub. The needle is retractable into plunger interior upon manipulation of the plunger member to actuate the energy-storage member latching member.
Auto-injectors for administration of a medicament within a prefilled syringe
An apparatus includes a housing, a carrier, and an expandable assembly. The housing defines an opening configured to selectively place a gas chamber of the housing in fluid communication with an exterior volume. The carrier is movably disposed within the housing and is coupled to a medicament container. A proximal surface of the carrier defines a portion of a boundary of the gas chamber. The expandable assembly has a first member and a second member. The first member is coupled to an elastomeric member disposed within the medicament container, and the second member includes a valve portion. The expandable assembly transitions from a collapsed configuration to an expanded configuration when the elastomeric member moves within the medicament container. The valve portion moves relative to the opening when the expandable assembly transitions from the first to the second configuration, placing the gas chamber in fluid communication with the exterior volume.
Injection Systems and Methods of Their Use
An injection system comprising a syringe barrel; a first sealing element and a second sealing element moveably disposed in the syringe barrel; an injection chamber between them; a puncture element extending from the first sealing element to deliver an injection agent from the injection chamber into a biological space, wherein one or more of the syringe barrel, the first or the second sealing element are configured to prevent proximal movement of the first sealing element past a pre-selected location, while allowing the second sealing element to come in contact with the first sealing element, the system is configured such that, when a force is applied on the second sealing element in a distal direction, in response to a first opposing force, the puncture element advances and in response to a second opposing force, the puncture element remains stationary and the injection agent is conveyed through the puncture element.
Safety syringe having a retracting needle and being pre-fillable with two active ingredients
The single-use safety syringe having a manual and/or automatic retracting needle preventing re-use thereof comprises a needle, a piston with a tightening seal and a cylindrical body having, at an end thereof, a connector provided with a calibrated attaching hole for the needle and open, at another end thereof, for inserting the piston, comprising, internally of the cylindrical body, a separating seal of a first chamber comprised between the separating seal and the connector in which a first active ingredient is positioned and a second chamber comprised between the separating seal and the tightening seal in which a second active ingredient is positioned, the separating seal having a connecting channel between the first and second chamber, closed by a pressure limiting valve, first engaging means further being provided, activatable for engaging the separating seal to the needle and second engaging means activatable for engaging the separating seal to the piston.
Safety syringe
An apparatus for use with a syringe for providing a safety syringe, the safety syringe including a plunger configured during an inward stroke to expel a substance from a hypodermic needle attached at an open end of a barrel of the syringe, the apparatus including: a biasing member configured to bias a sheath towards a closed position at least partially covering the hypodermic needle, wherein the biasing member is configured to be released at a point on the inward stroke of the plunger to urge the sheath towards the closed position.
Huber safety needle
Disclosed is a Huber needle assembly that may include an upper body connected to a lower body, the assembly being structured to retain a needle for insertion/extraction of the needle into/from an insertion site. The upper body can statically retain the needle while the lower body may slidably receive the needle. The lower body can further include a catch that engages a tip of the needle and/or misaligns the tip of the needle with a needle aperture of the lower body to place the assembly in a safety-lock position, preventing rebound, needle-stick injury, and/or any type of exposure of the needle tip to an environment outside of the lower body. The assembly can further bias the needle in a direction so as to prevent re-emergence of the needle tip after being withdrawn into the lower body.
Protection device for a needle
The invention relates to a protection device (1) for a needle (203) of a tip (201) of a drug delivery device (202), comprising: —fixing means (2) for fixing the protection device to said tip, —protective legs (4) capable of transitioning from a first configuration ration in which they cover the needle, to a second configuration in which the needle is exposed, and to a third configuration in which they cover the needle, via pivot links, —removable maintaining means for maintaining the protective legs in their first configuration, —retaining means (9, 10) for retaining the protective legs in their third configuration, said pivot links comprising elastic return means (5) for automatically transitioning the protective legs from their first configuration to their second configuration. The invention also relates to an assembly comprising a drug delivery device and said protection device, and to a method for manufacturing said protection device.
AUTO-INJECTORS FOR ADMINISTRATION OF A MEDICAMENT WITHIN A PREFILLED SYRINGE
An apparatus includes a housing, a carrier, and an expandable assembly. The housing defines an opening configured to selectively place a gas chamber of the housing in fluid communication with an exterior volume. The carrier is movably disposed within the housing and is coupled to a medicament container. A proximal surface of the carrier defines a portion of a boundary of the gas chamber. The expandable assembly has a first member and a second member. The first member is coupled to an elastomeric member disposed within the medicament container, and the second member includes a valve portion. The expandable assembly transitions from a collapsed configuration to an expanded configuration when the elastomeric member moves within the medicament container. The valve portion moves relative to the opening when the expandable assembly transitions from the first to the second configuration, placing the gas chamber in fluid communication with the exterior volume.
Safety device with collapsible housing and trigger activation
Drug delivery safety devices having trigger activation systems activated by pressure against the skin of a patient and which automatically shield the needle after withdrawing the needle from the skin of the patient.
