A syringe for medical use having a barrel with a longitudinally extending tubular fluid chamber and at least one longitudinally extending, outwardly facing, substantially flat indicia display surface disposed proximally to the fluid chamber, a plunger slidably inserted into the fluid chamber, a needle projecting forwardly from the barrel in fluid communication with the fluid chamber; and a fixed length needle safety device having an activation handle slidably engaging the barrel and a forwardly projecting needle tip shield encircling the needle that moves forwardly to cover a tip end of the needle when the activation handle is moved forwardly following use of the syringe.

Rectangular syringe

An auto-injection syringe shaped similar to a credit card and having a biased injection mechanism operable to drive a needle into a user's body by a fixed distance to dispense a dose of fluid at a subcutaneous location. A safety may be provided to avoid undesired actuation of the injection mechanism. After the safety is bypassed, a trigger may be actuated by the user to allow operation of the injection mechanism. A reciprocating needle-cover resists casual view of the needle by the user during and after use of the syringe. A locking mechanism automatically holds the needle-cover at an extended position to isolate the needle from further contact and to resist re-use of the syringe.

Autoinjector

Described is an autoinjector comprising a case, a door hingedly coupled to the case and having an open position and a closed position, a plunger slidably disposed in the case, and at least one drive spring applying a biasing force on the plunger relative to the case, wherein the door is operably coupled to the plunger, and wherein rotation of the door from the closed position to the open position moves the plunger from a distal position in the case to a proximal position in the case and compresses the at least one drive spring.

Compact mechanical pump
10376636 · 2019-08-13 · ·

A compact mechanical pump is provided. The pump is adjustable between a compact form and an expanded form, where the pump can be reduced to a compact form for ease of portability and storage and to the expanded form for use as a pump.

Syringe

A syringe (200, 400) for use in a medication delivery device (100) comprises a vial. The vial (201, 411) comprises a chamber (206). The chamber is configured to receive a piston or plunger (205, 416). The syringe further comprises a needle attachment point (202), for the attachment of a hypodermic needle (204). The chamber is offset from the needle attachment point.

Hand-held drug injection device and dose setting limiter mechanism therefor

The present invention relates to a drive mechanism of a drug delivery device for dispensing of a dose of a medicament, the mechanism comprising: a housing (20), a piston rod (120) extending in an axial direction (1, 2) to operably engage with a piston (14) of a cartridge (12), a drive sleeve (90) rotatably supported in the housing (20), at least partially enclosing the piston rod (120), the drive sleeve (90) is operably releasable from the piston rod (120) for setting of a dose and the drive sleeve (90) is operably engageable with the piston rod (120) for dispensing of the dose, a dose limiting member (130) threadedly engaged with the drive sleeve (90), rotatably locked to the housing (20) and being displaceable in axial direction (1, 2) in response to a rotation of the drive sleeve (90) relative to the piston rod (120), at least one stop member (124) provided on the piston rod (120) to engage with the dose limiting member (130) for impeding a further displacement of the drive sleeve (90) relative to the piston rod (120), when a maximum dose configuration has been reached.

Universal Dosage Verification System and Method for Medical Syringe
20250229030 · 2025-07-17 ·

Systems and methods of a dosage verification system are disclosed that can be used by a healthcare worker or an individual self-administering an injection to create a digital record verifying the dosage of a medicinal fluid drawn into a syringe prior to an injection. The dosage verification system includes a medical syringe and an imaging device configured to view and selectively capture, process, store, and transmit a digital image of the syringe from which the volumetric dose of medicinal fluid drawn into the fluid chamber of the barrel can be determined and/or verified prior to an injection.

MEDICAL INJECTOR WITH COMPLIANCE TRACKING AND MONITORING

A system includes a medicament delivery device and a container configured to receive at least a portion of the medicament delivery device. The medicament delivery device includes an actuator and a first electronic circuit system. The actuator is configured to initiate delivery of a medicament into a body when the actuator is moved from a first position to a second position. The first electronic circuit system is configured to output a first electronic signal when the actuator is moved from the first position to the second position. The container includes a second electronic circuit system configured to receive the first electronic signal. The second electronic circuit system is configured to output a second electronic signal associated with the first electronic signal.

Drive mechanism for a drug delivery device

The present invention relates to a drive mechanism of a drug delivery device for setting and dispensing of a dose of a medicament, the drive mechanism comprising: a housing, a piston rod to operably engage with a piston of a cartridge to displace the piston in a distal direction, a rotatable member arranged on an axially extending axis of rotation in the housing, said rotatable member being rotatable in a dose incrementing direction against an action of a spring element and being operably engageable with the piston rod during the dispensing of the dose, and a clutch element comprising at least one radially displaceable clutch element to engage with a rim of the rotatable member with a variably adjustable strength.
