A method for using a dose divider comprising first and second arms, each having a front portion that jointly forms a channel for receiving a syringe plunger rod. An elastic hinge pivotably connects the first and second arms so that the dose divider is reversibly movable between a first configuration and a second configuration. In the second configuration, the dose divider is configured to receive a plunger rod in a channel formed between the front portions of the first and second arms. The channel is configured to receive a particular outer shape of the plunger rod. The front portions of the first and second arms are closer when the dose divider is in the first configuration than when it is in the second configuration. The method includes moving the dose divider from the first configuration to the second configuration by applying force to the first and second arms so that the first arm pivots in a first direction relative to the second arm using the elastic hinge.

A dose divider, releasably attached to the plunger rod of a syringe, includes first and second arms. The front portions of the first and second arms form a channel between them for receiving the plunger rod. An elastic hinge pivotably connects the first and second arms so that the dose divider is reversibly movable between the first and second configurations. When the dose divider is in the second configuration, it is configured to receive the plunger rod in the channel through an opening formed between the front portions of the first and second arms. The channel has a shape configured to receive a particular outer shape of the plunger rod. The front portions of the first and second arms are closer together when the dose divider is in the first configuration than when it is in the second configuration.

A method of using a dose dispenser that includes a first arm and a second arm that each have a front portion that together form a channel for receiving a syringe plunger rod. A resilient hinge pivotably couples the first arm and the second arm such that the dose dispenser is reversibly movable between a first configuration and a second configuration. In the second configuration, the dose dispenser is configured to receive the plunger rod in a channel formed between the anterior portion of the first arm and the anterior portion of the second arm. The channel is configured to receive a particular outer shape of the plunger rod. The anterior portion of the first arm and the anterior portion of the second arm are closer when the dose dispenser is in the first configuration than when in the second configuration. The method includes moving the dose dispenser from the first configuration to the second configuration by applying a force to the first arm and the second arm such that the first arm pivots in a first direction relative to the second arm using the resilient hinge.

A medicament delivery system includes a syringe and a plunger rod. The plunger rod includes a first region having a first outer configuration and a second region having a second outer configuration different from the first outer configuration. A blocking element is configured to be disposed at the proximal end of the syringe and disposed around the plunger rod, and the blocking element allows the plunger rod to move relative to the syringe over a first range of motion to expel a first dose of medicament, and blocks the plunger rod from moving relative to the syringe over a subsequent range of motion to expel further medicament. The blocking element is configured to be removable from the plunger rod. Once the blocking element is removed from the plunger rod, the plunger rod is free to move over a subsequent range of motion relative to the syringe to expel further medicament.

A topical dosing dispenser including a child resistant closure system and / or a child resistant rotatable base system.

The invention provides a rotation stroke compensation mechanism and a dosing distributor, and the rotation stroke compensation mechanism comprises a driving rotating part which is used for being connected with a driving assembly and rotating under the action of the driving assembly; the driven rotating part is rotationally connected with the driving rotating part and is used for winding an object to be wound; the damping assembly is arranged between the driving rotating piece and the driven rotating piece and used for generating torque between the driving rotating piece and the driven rotating piece, so that the driving rotating piece applies driving torque to the driven rotating piece through the damping assembly; wherein the driving torque is not greater than a preset threshold value; the preset threshold value is the driving torque generated when the driving rotating piece and the driven rotating piece generate relative rotation. The rotation stroke compensation mechanism can play a role in stroke compensation, and no fool-proof design is needed.

A package configured to store and dispense a fluid. The package includes a container and a dose dispenser for closing an opening to the container. The dose dispenser includes a body portion having a discharge aperture. The discharge hole may be closed and opened using a flap of the dose dispenser.

The application provides a rotary stroke compensation mechanism and a drug dispenser. The rotary stroke compensation mechanism comprises a driving rotary part, which is connected to a driving assembly and rotates under the action of the driving assembly; a driven rotary part, which is rotationally connected to the driving rotary part and is used to wind a to-be-wound object; and a damping assembly, which is arranged between the driving rotary part and the driven rotary part and is used to generate a torque between the driving rotary part and the driven rotary part, so that the driving rotary part applies a driving torque to the driven rotary part through the damping assembly. The driving torque is not greater than a preset threshold. The preset threshold is the driving torque when the driving rotary part and the driven rotary part generate relative rotation. The rotary stroke compensation mechanism can play a stroke compensation role and does not need to be designed to prevent mistakes.
