  • Patent number: 10709843
    Abstract: A device for repetitive needleless injection of a liquid into a surface includes a handheld unit that includes at least a cell that is fillable with the liquid. A propulsion mechanism is configured to apply a sequence of pressure pulses to the liquid. Each pulse ejects a micro jet of the liquid from the cell via an orifice between the cell and the exterior of the handheld unit with a velocity that is sufficient to enable the micro-jet to penetrate into the surface. A reservoir is connected to the cell by a conduit to enable the liquid to flow from the reservoir to the cell to replace the liquid that is ejected in the micro-jet. A controller is configured to operate the propulsion mechanism repeatedly so as to eject the sequence of the micro-jets.

  • Patent number: 10695504
    Abstract: A drug delivery system comprises means to create a log of expelled dose amounts of drug. Stored dose amounts determined within a given time period are combined to a single combined dose amount. The given time period is initiated by a detected expelling event taking place (i) a given amount of time after a previous detected expelling event, or (ii) after a given detected action. By this arrangement it is possible to create a log corresponding to what a user considers to be a single dose, i.e. combining “split doses” to create a single log entry for a per se split dose.

  • Patent number: 10688251
    Abstract: A self-righting tip cap includes a cap body having a generally oblate spheroid external shell geometry defining a first end and a second end. The first end has a base surface, and at least one clip extends from the body towards the second end. A coupling element accessible from the second end provides removable attachment of the tip cap to a cooperating coupling of a syringe or other female ENFit connectors. The geometry of the tip cap causes it to tend toward uprighting itself when dropped onto a flat surface, such that the base surface is in contact with the flat surface and the coupling element is accessible in an upward facing orientation. According to example forms, at least one rib of a female coupling can become interengaged with at least a portion of the clips such that the self-righting tip cap can be pulled and/or rotationally moved relative to the female coupling to be removed therefrom.

  • Patent number: 10646661
    Abstract: A needle assembly for mounting on an injection device which comprises a body configured to be attached to an injection device in use; a double ended needle; and a needle shield coupled to the body. The needle shield is arranged for axial movement with respect to the body. The needle assembly has an injection configuration, in which the shield is positioned such that the forward tip of the needle projects beyond a forward end of the shield. The needle assembly also has a shroud configuration, in which the shield is positioned such that the forward end of the shield extends beyond the forward tip of the needle. The needle assembly further comprises a needle support fixed relative to the body when the needle assembly is in the injection configuration. Movement of the shield from the injection configuration to the shroud configuration axially displaces the needle support relative to the body.

  • Patent number: 10583245
    Abstract: A drug delivery device includes a housing with at least one pressure communication channel or aperture, which distributes a negative fluid pressure across its base to draw tissue against the device. The device can also include a porous, adhesive layer over the channel(s) or aperture(s), for attaching to tissue. The device can also include a pressure sensor for determining whether there is proper attachment. Further, a bladder may be used instead of the adhesive layer for attaching the device. The bladder, in a partially inflated state, can apply constant pressure across a contact surface causing a flexible adhesive layer attached to the bladder to confirm and adhere to the tissue. Subsequent evacuation of the bladder causes it to deflate and collapse or retract, thereby causing the flexible adhesive layer to pull and stretch the tissue toward the base.
