  • Publication number: 20230140353
    Abstract: A medical device includes a base having a needle channel and a first surface configured to be secured to a patient's skin. An insertable member is configured to be secured to the base with a length portion of the insertable member extending out of the needle channel at the first surface, for insertion through the patient's skin at an insertion site. A septum extends across the needle channel. The septum has a body through which an insertion needle may be selectively extended to facilitate the subcutaneous insertion of the length portion of the insertable member. The septum provides a liquid seal across the needle channel. The needle channel and the septum provide a sealed volume in which a limited amount of blood or other fluid from the insertion site may be held.

  • Patent number: 11517663
    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.

  • Patent number: 11458247
    Abstract: A drug delivery device includes a blunt cannula and a reservoir. The blunt cannula has a cylindrical wall that defines an axial passage between a first end and a second end of the blunt cannula. The wall has at least a first tapered region at the first end to define an opening in fluid communication with the axial passage and adapted at the first end to resist interruption of fluid flow through the axial passage and out of the first end of the blunt cannula. The reservoir is connected to the second end of the blunt cannula.

  • Publication number: 20210369981
    Abstract: A wearable drug delivery device that can deliver a liquid drug stored in a container to a patient or user is provided. A soft needle or cannula can be placed in fluid communication with the liquid drug and can be coupled to a needle insertion component that provides access to the patient. A drive system of the drug delivery device can expel the liquid drug from the container to the patient through the soft needle or cannula. The wearable drug delivery device can include components for preventing backflow and eliminating air within the liquid drug. As a result, the comfort of the patient can be enhanced and correct drug dosages can be provided when using the drug delivery device.

  • Publication number: 20190358411
    Abstract: Injection devices for drug delivery and related methods of use and manufacture are disclosed. The injection device may include an outer casing, a container disposed in the outer casing, an injection drive mechanism, and an instructional marker disposed on an exterior surface of the outer casing. The container may include an interior chamber for storing a drug, a subcutaneous delivery member, and a stopper movably disposed in the interior chamber. The injection drive mechanism may be configured to move the stopper to expel the drug through an opening in a distal end of the subcutaneous delivery member upon activation. The instructional marker may indicate a tiling direction for tilting the injection device when the subcutaneous delivery member is inserted into a patient so as to inhibit tissue from occluding the opening in the distal end of the subcutaneous delivery member.

  • Publication number: 20190275241
    Abstract: A drug delivery device includes a housing defining a shell and an inner volume, a container, a drive mechanism, a needle assembly, a fluid flow connection, and a backflow prevention mechanism. The container has an inner volume to contain a medicament to be administered to a user. The drive mechanism is at least partially disposed within the housing and exerts a force to urge the medicament out the container. The fluid flow connection is coupled to the container and the needle assembly and allows the medicament to flow from the container to the needle assembly to be administered. The backflow prevention mechanism is associated with at least one of the container, the fluid flow connection, or the needle assembly and includes at least one flow restrictor to restrict a fluid from flowing from the needle assembly to the container.
