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tip to a final insertion state and release of an associated manual insertion load, the plunger tip may be proximally withdrawn, pulling the retractable needle proximally relative to the needle housing to a safe locked and retracted state wherein it is no longer exposed for injection.

FLUIDIC SUBSYSTEM FOR MULTI-USE DRUG-DELIVERY DEVICE
20220088308 · 2022-03-24 ·

The present disclosure relates to drug-delivery apparatuses, and in particular, to a drug-delivery apparatus with a fluidic subsystem that can be used to deliver multiple injections to a patient from a drug container storing a drug fluid. The fluidic subsystem may include multiple injection-needle compartments and re-sealable septa to allow multiple accesses to the drug container, while also preserving the sterility of the drug fluid and of the fluid pathway through which the fluid is delivered to a patient. In some embodiments, the fluidic subsystem may be used to deliver drug fluids that do not contain any preservatives (e.g., non-preserved drugs).

DEVICE FOR PREVENTING NEEDLE REUSE AND INJURY, SYRINGE, AND METHOD
20220111155 · 2022-04-14 ·

Device for preventing needle reuse and injury has a needle cap or enclosure, a body, and a needle. The needle cap and/or body is movable relative to the other from (i) a first position wherein the needle is received within and enclosed by the needle cap to prevent needle injury; (ii) to a second position wherein the needle is passed through the needle cap to penetrate tissue; and (iii) to a third position wherein the needle is within and enclosed by the needle cap, and the needle cap and body are locked to prevent needle reuse and injury. The needle cap conceals the needle from view before, during and after the patient injection. An intra-needle one-way valve allows liquid flow therethrough in a direction from an inlet toward an outlet of the needle, and prevents liquid flow in an opposite direction to prevent cross-contamination between the needle and a syringe.

Protector housing plastic spike with flash intended for DVO last drop extraction

A device for transferring fluids in a closed system transfer device using flash for last drop extraction and to reduce coring. The device including a piercing member having a distal end and a proximal end and defining a longitudinal fluid channel. A first opening positioned at the distal end of the piercing member wherein the first opening is in fluid communication with the longitudinal fluid channel. A cover or flash positioned over the first opening. The cover including a pre-cut pattern wherein the cover opens along the pre-cut pattern upon application of a distally directed force from the longitudinal fluid channel. The distal end including the first opening having a steep taper to facilitate last drop extraction.

Auto-injector

The auto-injector consists of a front unit connected to a rear unit, wherein the front unit contains a syringe holder with a syringe coaxially sliding between injecting and secure positions within an activating element preloaded via an ejection spring to secure a trigger button through a stopper located in the rear unit. The rear unit contains a syringe pusher with a plunger managed via a controller coaxially moved by an injection spring to the front unit upon activating the trigger for injecting medication. After the injection, the activating elements revert to allow the controller to release the syringe which moves into to secure position with the syringe holder and the plunger by the ejection spring. When the syringe enters a safe position, the controller moves by the injection spring between the activating element and the syringe holder to prevent the syringe from sliding toward the injection side.

SYRINGE ASSEMBLY
