  • Publication number: 20220288324
    Abstract: A drug delivery device including a housing, a drug storage container, and a removable cap is provided. The housing includes a housing camming feature and a longitudinal axis and includes an opening. The drug storage container includes a delivery member having an insertion end configured to extend at least partially through the opening during a delivery state. The removable cap defines a cap camming feature and is configured to be removably coupled with the housing such that the removable cap has a storage position where the removable cap is coupled with the housing and at least partially covering the opening and a removed position where the removable cap is not coupled with the housing. The cap camming feature and the housing camming feature are configured to translate rotational motion into axial motion such that, upon rotational movement of the removable cap, the cap camming feature and/or the housing camming feature urge the removable cap along the longitudinal axis.

  • Publication number: 20210228818
    Abstract: The present invention relates to a pre-filled disposable injection device and a needle cannula in combination. The prefilled disposable injection device (1) is made from a housing (2) containing a non-exchangeable cartridge (10) for storing a liquid drug sufficient for a number of injections. The proximal end of the pre-filled injection device (1) carries the dose setting button (3) and the distal end carries the needle cannula (20) having a lumen (21) through which the settable dose is expelled. The distal end (23) of the needle cannula (20) is covered by a telescopic needle covering shield (30) which shield (30) can operate between a first position covering the tip (24) of the needle cannula (20) and a second retracted position allowing an injection to be performed.

  • Patent number: 11052185
    Abstract: The present invention concerns a medical injection device for apportioning set doses of a preservative containing liquid drug. The injection device comprises a housing supporting a cartridge containing the preservative containing liquid drug and a needle cannula for transferring the liquid drug from the cartridge and through the skin of a user. Further, a needle shield which is axially movable in relation to the housing is also present. The axially movable shield carries a cleaning reservoir for cleaning at least the tip of the needle cannula between subsequent injections and the cleaning reservoir is preferably filled with preservative containing liquid drug directly from the cartridge upon initiation of the injection device. In order to eliminate any overpressure being built up inside the cleaning reservoir during the filling process, the cleaning reservoir is provided with an outlet configured to be permanently sealed by a user activated operation.

  • Publication number: 20210121633
    Abstract: A drug delivery device may include a housing having an opening and a drug storage container having a body portion with a proximal end and a distal end and a delivery member extending from the distal end of the body portion. The device may also include a plunger moveable toward the distal end of the drug storage container to expel a drug from the drug storage container through the delivery member and a plunger biasing member configured to urge the plunger toward the distal end of the drug storage container. The device may further include a container holder configured to support the drug storage container with respect to the housing such that a resultant force acting on the drug storage container from the plunger biasing member is at least substantially completely borne by the distal end of the body portion of the drug storage container.

  • Publication number: 20210093797
    Abstract: A drug delivery device may include a housing having an opening and a drug storage container including a delivery member with an insertion end configured to extend at least partially through the opening. A biasing member may initially be retained in an energized state, and may be released to drive a plunger to expel a drug from the drug storage container. The plunger may be configured to selectively rotate from an initial rotational position to a second rotational position under a biasing force exerted by the biasing member, and translate linearly in a distal direction to drive the stopper through the drug storage container after rotating from the initial rotational position to the second rotational position. A releaser member may have an initial position wherein the releaser member retains the biasing member in the energized state, and a second position wherein the releaser member generates an audible end-of-dose signal.

  • Publication number: 20210093792
    Abstract: A drug delivery device and method of using the same may include a housing having an opening and a drug storage container including a delivery member with an insertion end configured to extend at least partially through the opening. The drug storage container may be coupled with the housing such as to substantially prevent relative movement therebetween. A guard may be positioned adjacent to the opening and operably coupled with the plunger biasing member such that a relative movement between the guard and the housing permits release of a plunger biasing member to urge a plunger in to expel a drug from the drug storage container. A lock component may be configured to resist the relative movement between the guard and the housing until the lock component is released by a user force, whereafter the user force drives the housing and the drug storage container toward an injection site.

  • Publication number: 20210093796
    Abstract: A drug delivery device may include a housing having an opening and a drug storage container including a delivery member having an insertion end configured to extend at least partially through the opening during a delivery state. The device may also include a guard moveably positioned adjacent to the opening and a plunger having a generally cylindrical body portion extending along a longitudinal axis of the container and at least one flange extending radially outwardly from the body portion, wherein the plunger is moveable toward the distal end of the container to expel a drug through the delivery member. The device may further include a plunger biasing member configured to urge the plunger toward the distal end of the container and a releaser member defining a guide configured to receive the at least one flange and an indicator configured to generate an audible signal indicating an end of drug delivery.

  • Publication number: 20200297918
    Abstract: The invention relates to a medical injection device for injection of a liquid drug. The injection device comprises a housing structure with a cartridge and needle cannula. Further an axially movable cleaning reservoir is provided which is movable in relation to the housing structure, and which cleaning reservoir contains a liquid cleaning agent. The distal tip of the needle cannula is positioned and thus cleaned inside the cleaning reservoir between subsequent injections. According to the invention, the cleaning reservoir connects to an overflow reservoir through a one-way pressure valve such that the cleaning agent and/or air is flowable from the cleaning reservoir and into the overflow reservoir.
