A fixed amount discharge container includes: a syringe barrel 3; and a piston 8 inserted in the syringe barrel 3 so as to be movable in a longitudinal direction, thereby defining a fluid chamber between the syringe barrel 3 and the piston 8. One of the syringe barrel 3 and the piston 8 includes a guide 3c that is extended in a longitudinal direction. The other of the syringe barrel 3 and the piston 8 includes a slider 9 that is movable in the guide 3c along with the other of the syringe barrel 3 and the piston 8. The guide 3c is provided with a target position contact portion 3j which the slider 9 contacts when an amount of the fluid chamber is equal to a target amount.

The present invention provides a system (1) comprising: a pen injection device (10) holding a specific type of medicament and comprising a dose expelling mechanism and pen communication means (15), a mobile communication unit (30) comprising mobile communication means (35) adapted to communicate with the pen communication means (15), and a software application program configured to determine a recommended type of medicament to be delivered to a user based on information indicative of a physiological condition of the user, wherein the pen injection device (10) further comprises indication means which in a first state indicates that the dose expelling mechanism is to remain idle and in a second state indicates that the dose expelling mechanism is available for operation, and wherein the mobile communication unit (30) is configured to, via a communication from the mobile communication means (35) to the pen communication means (15), a) prompt a change of state of the indication means from the second state to the first state in response to the recommended type of medicament to be delivered differing from the specific type of medicament, and/or b) prompt a change of state of the indication means from the first state to the second state in response to the recommended type of medicament to be delivered corresponding to the specific type of medicament.

A needleless injector has a syringe body having an opening at one end, a piston housed within the syringe body for urging a liquid within the syringe body through the opening and a ram for driving the piston. A shock absorbing component is provided for reducing an initial transfer of force from the ram to the piston. The initial rate of pressure increase on the liquid is reduced, thereby controlling the rate of collapse of gas bubbles in the liquid.

A fluid delivery device comprises a fluid reservoir for containing medicament. The fluid reservoir is sealed proximate one end with a sliding seal piston. A delivery path is configured to fluidly couple the fluid reservoir and a patient wearing the fluid delivery device. A basal engine mechanism is configured to directly or indirectly move the sliding seal piston in the fluid reservoir at a controlled basal rate. A bolus mechanism configured to move the basal engine relative to the fluid reservoir and directly or indirectly move the sliding seal piston in the fluid reservoir a discrete bolus amount at a time.

The present invention relates to a finger grip (1) arranged to be connected to a syringe barrel having a plunger and a plunger rod for driving said plunger. The finger grip comprises a body having a lower side with finger supporting surfaces (13) for supporting fingers of a user during handling and an engagement member (5) being moveable between an inactive position where the engagement member is arranged not to engage with the plunger rod of the syringe barrel and an active position where the engagement member is arranged to engage with a grooved surface on the plunger rod of the syringe such that feedback is given to a user as the plunger is moved relative to the finger grip. An activation member (7) for moving the engagement member from said inactive position to said active position is built-in into the finger grip.

Devices for delivery of individual units of a medicament and methods for their use are provided. Such a delivery device comprises an exostructure permanently attached to a syringe comprising a barrel and a plunger with one or more ratchet surfaces, a cam mechanism to advance the plunger a plurality of set distances in a first direction to deliver a single individual unit of the medicament per each set distance, and a locking pawl to prevent the plunger from being retracted in a second direction opposite the first by interfacing with the ratchet surfaces. The locking pawl also produces tactile feedback, audible feedback, or both when the plunger is depressed to advance the plunger the set distance. Each of the individual units comprise a measured volume of the medicament, and the plunger can repeatedly be depressed and repeatedly engage with the locking pawl to deliver repeated measured volumes of the medicament.

Apparatus and methods for filtering syringe fluid contents through a syringe-embedded filter. The filter may be sealed within a housing lodged distal to unfiltered fluid contents, proximal a syringe distal outlet, with a housing exterior sealed fluid-tight against a syringe inner wall. Before filtering, the housing may block access of unfiltered fluid to the filter. The unfiltered fluid may be sealed between a syringe plunger, the inner wall and the housing. Distally directed urging of the unfiltered fluid may unblock the housing to a flow of unfiltered fluid to the filter. Fluid-tight sealing within the housing may limit fluid passage to the distal outlet to a path through the filter. The unfiltered fluid may be urged through the unblocked housing and the filter. Filtered fluid, relatively free of particulate matter sized greater than a filter average pore size, may flow to the distal outlet for delivery to a target site.
