T-SHAPED SLOT LOCKING SAFETY SYRINGE
20210113771 · 2021-04-22 ·

To prevent accidental needle stick injuries, a syringe has a plunger configured to pull the syringe into the syringe barrel after clinical use. The syringe has an additional safety feature that restricts subsequent movement of the plunger. After the needle has been retracted in its entirety within the barrel of the syringe, movement of the plunger is restricted by a two-part locking mechanism, a notch on the plunger and a T-shaped slot on the barrel with a one-way catch section to prevent the needle tip from being pushed accidentally through the barrel wall.

INJECTION SYRINGE
20210038826 · 2021-02-11 ·

A syringe provided with a body, a piston capable of sliding in the body, and an injection device comprising a needle oriented along a longitudinal axis and a casing removably secured to the body and carrying said needle. The casing comprising a plurality of flexible tabs, each provided with a stop. The piston comprising a docking system having a housing comprising a flange configured to hold the stops of the flexible tabs in the housing in an insertion position in which the tabs are inserted into the housing, the plurality of tabs in opposing areas around the longitudinal axis. The flange comprising bearing areas configured to be in contact with corresponding tabs in the insertion position. The tabs are configured to exert an elastic pressure on corresponding bearing areas in the insertion position, and the bearing areas are dissymmetrical relative to the longitudinal axis.

Safe syringe

A safe syringe includes a barrel, a needle seat and a plunger, wherein the needle seat has a hook rod, a linkage deformation portion and a barrel clamping portion; and the plunger has a rod body, and a hook insertion hole which can be sleeved with the hook rod of the needle seat and compress the linkage deformation portion for elastic deformation such that the barrel clamping portion of the needle seat is not clamped into the seat clamping slot of the barrel, and the hook insertion hole can hook the hook rod of the needle seat to move the needle seat. The safe syringe can allow stable positioning and quick pullback of the needle seat and effectively reduce liquid medicine residue.

Medical device with resiliently retracting safety needle

A medical device for percutaneous or venous access for the purposes of administering a fluid to a patient or sampling from one is disclosed. The device includes a cannula holder that has a part or portion of cross-section which is reduced or different from its distal end and proximal end. The part or portion of reduced or different cross-section allows the cannula holder to deform within the body of the device when activating means are activated to separate the cannula holder from an immobilising member allowing the cannula holder to move in the body of the device and re-enter and disappear within such body of the cannula.

Fluid delivery device and method

A fluid delivery injector comprises a syringe defining a barrel; a plunger and a hollow needle provided within the barrel adapted for linear movement parallel to a longitudinal axis with a distal tip of the needle contained within the syringe. A fluid retention reservoir is defined at least in the barrel and is in fluid communication with the needle when pressure is applied to the fluid in the reservoir and to the plunger for moving the needle out of the barrel. A spring may be provided for retracting the needle when pressure is released from the plunger.

SAFETY SYRINGE

One embodiment is directed to a safety syringe system, comprising: an off-the-shelf syringe assembly comprising a syringe body and a plunger tip; a needle assembly removably coupleable to the distal end of the syringe body such that medicinal fluid may be transferred through a retractable needle coupled to a needle housing comprising the needle assembly upon insertion of the plunger tip relative to the syringe body; and a plunger control assembly coupled to the plunger tip and configured to facilitate manual insertion of the plunger tip relative to the syringe body; wherein upon insertion of the plunger tip to a final insertion state and release of an associated manual insertion load, the plunger tip may be proximally withdrawn, pulling the retractable needle proximally relative to the needle housing to a safe locked and retracted state wherein it is no longer exposed for injection.

Syringe
10434256 · 2019-10-08 · ·

A syringe includes a hollow body, a piston and a seal. The hollow body has a surrounding hollow body surface and forms a passage therein. An axis is formed in an axial longitudinal direction of the hollow body and the passage has a rear body opening and a front body opening arranged opposite to one another in the longitudinal direction. A first needle seat is formed at the front body opening, in which a needle cannula is arranged and relative to which the needle cannula is movable along the axis. The piston is arranged in the hollow body and is movable in the passage along the axis. The seal is able to be cancelled such that a receiving chamber and a supply space of the syringe are in flow communication in a release position.

NEEDLE SAFETY ASSEMBLY
