HYBRID BLUNT CANNULA WITH PUNCTURE NEEDLE ASSEMBLY
20220105279 · 2022-04-07 ·

A hybrid blunt cannula with puncture needle assembly provides an outer cannula member comprising a needle channel, an eye, a stopper member disposed at the second end of the cannula member, and an inner needle disposed inside the needle channel and coupled to buttons. The buttons follow a translation path between a static position and an insertion position. The static position enables the free end of inner needle to be proximal to the second end of the outer cannula member, and within the needle channel. The insertion position enables the free end of the inner needle to be proximal to second end of the outer cannula member and partially outside of the outer needle's channel. The free end of inner needle is operable to penetrate the stopper member while in insertion position for discharge of a liquid through the eye.

Medical Syringe with Retractable Needle and Modified Plunger Handle with Concave Pressure Application Surface
20220062558 · 2022-03-03 ·

A medical syringe having a forwardly projecting needle that is selectively retractable following use and also having a specially configured plunger handle and thumb cap that cooperate to form a concave pressure application surface (“CPAS”). The concave pressure application surface at the rear of the plunger handle enables the subject medical syringe to achieve functional advantages, each with an associated therapeutic benefit, that are not achieved with use of the prior art devices.

COMBINED NEEDLE AND CANNULA

A device for performing injections in a patient includes a syringe holder with a needle guard, a cannula extending from the syringe holder, a needle slidably disposed over the cannula, and a slider on the syringe holder. The cannula has a blunt tip and a cannula length, and the needle has a sharp tip and a needle length that is shorter than the cannula length. The slider is coupled with the needle and is configured to slide the needle along the cannula from an extended position, in which the sharp tip of the needle is located at or immediately adjacent the blunt tip of the cannula, to a retracted position, in which the sharp tip is housed within the needle guard of the syringe holder.

The present invention relates to a syringe, and more particularly, to an apparatus obtained by improving an conventional syringe formed with an injection flow passage including an injection needle, so as to share a portion of the injection flow passage except the injection needle or to form a suction flow passage completely independent of the injection flow passage, thereby further smoothing suction of a liquid medicine. The syringe is configured such that the separate suction flow passage bypassing the injection needle is formed in an conventional syringe to more smoothly perform the suction of the liquid medicine, thereby maximizing user's convenience and marketability of the product.

MULTI-LUMEN SYRINGES FOR INTRAOCULAR INJECTIONS
20210298949 · 2021-09-30 ·

There is provided herein a multi-lumen syringe for intraocular injection, including a first lumen, a second lumen, one or more needles fluidly connected to the lumens, and a needle sheath disposed about the one or more needles; wherein the needle sheath includes a plurality of n proximity/contact/pressure actuators on a distal rim of the needle sheath; wherein the syringe is switchable between at least two configurations: a first configuration in which at least one of the actuators is not actuated and each tip of the one or more needles is proximally positioned, and secured, relative to the distal rim; and a second configuration in which the n actuators are actuated, and the one or more needles are allowed to distally extend beyond the distal rim.

Cap for a drug delivery device

A cap (120) for a drug delivery device (1) having a distal end (121) and a proximal end (122); the cap (120) having an opening at the proximal end and further comprising an outer cap element (130) and an inner cap element (131) being located inside the outer cap element (130), the inner cap element (131) comprising a deformable region (151) and a cap snap means (149); wherein the deformable region (151) of the inner cap element (131) is deformable into a gap (143) between the inner cap element (131) and the outer cap element (130).

APPARATUS AND METHOD FOR INJECTING MATERIAL INTO ORGANIC TISSUE
20210038808 · 2021-02-11 ·

A problem with injecting cells such as fat cells into organic tissue to act as a filler material is that the cells must be distributed evenly and reasonably thinly to ensure that all of the injected cells are situated near to a blood supply and do not die. Injecting devices have been produced that use electronic controls and electro-mechanical mechanisms to improve distribution. The present approach however solves the problem of even distribution by coupling a skin surface sensing means to a plunger in a reservoir of the filler cells. In this way, the flow of cells out of a cannula relates directly to the rate at which the tip of the cannula penetrates the organic tissue into which the cells are being injected.

NEEDLE ADAPTER AND DEVICE FOR SOFT MATERIAL EXTRUSION OF CORE-SHELL STRUCTURES
20210060328 · 2021-03-04 ·

A two piece adapter for extrusion of cylindrical core-shell structures using conventional biomedical needles includes first and second adapter pieces. The first adapter piece includes first and second (core and shell) inlet ports. The core inlet port leads directly to a male Luer fitting attachable to a core needle and surrounded by a threaded chamber. The shell inlet port is led, via a side chamber, into the side of the threaded chamber. The second adapter piece attaches to the bottom of the threaded chamber and is configured to attach to a shell needle, so that the shaft of the core needle sits inside the shaft of the shell needle.
