A cartridge (100) for containing and dispensing a medicament, the cartridge (100) including a cartridge body (104) having an interior cavity (10B) therein, a stopper (112) movably disposed within the interior cavity (108), and a septum (116, 148) disposed at an opposite end of the interior cavity (108) from the stopper (112), for containing the medicament within the Interior cavity (108). The cartridge (100) also Includes a connection thread (120) integrally formed as a unitary construction of the cartridge body (104), the thread (120) being disposed at a first end of the cartridge body (104) for connecting a pen needle directly to the cartridge body (104) to pierce the septum (116, 148) and provide communication between the medicament and a patient end of the pen needle.
摘要:
A delivery device for delivery of a medicament to a user including a container defining a reservoir storing the medicament, a body in which the container is received, a spray nozzle arranged on one of the body and the container for receiving medicament expelled from the container, and a pusher actuatable for pushing the medicament from the container reservoir through the nozzle, said pusher being movable from a rest position to a fully activated position relative to said body in response to an actuating force. The assembly is particularly applicable to nasal syringes where it is desirable to deliver the medicament in the form of a spray.

Provided is an extended use self-contained, wearable medical device. The device is preferably configured with an infusion deployment mechanism for variably inserting and retracting an infusion needle to different depths, or completely retracting the infusion needle from the infusion site and then re-inserting the infusion needle after a predetermined period of time, throughout an infusion cycle for extending the viability of the infusion site. Another embodiment comprises dual needle deployment mechanisms which may also variably insert and retract the infusion needles. A flow sensor is preferably provided for detecting the stoppage of flow through the infusion cannula and signaling the needle deployment mechanism to attempt infusion at a different depth or to deploy a second infusion needle. A re-fillable reservoir assembly is preferably provided for supplying a drug over the extended use of the device. Another embodiment comprises a partially reusable and partially disposable medical device implementing the above features.

A medical injector is provided herein which includes first and second body portions rotatably coupled together; a displaceable plunger disposed in at least one of the first and second body portions; a spring disposed to advance the plunger; and, a releasable retainer for retaining the plunger in a first portion against force of the spring. The releasable retainer releases the plunger upon a predetermined extent of relative rotation between the first and second body portions, thus allowing the spring to advance the plunger. Advantageously, the subject invention provides a medical injector having an automated plunger drive which is triggered upon rotation of injector body portions, thereby minimizing premature or failed activations.

摘要:
A spray or injection device that includes a casing or a pusher that includes at least one tab radially moveable between a first radial position, in which the tab does not impede the movement of the pusher with respect to the casing, and a second radial position in which the tab opposes movement of the pusher. The pusher or the casing, respectively, includes at least one ramp-shaped projection configured to bring the tab into the second radial position and then allow it to return to the first radial position. The pusher or the casing further includes at least one stop between the pusher and casing to delineate the end of a first stroke corresponding to a first dose of medicament, and the beginning of a second stroke corresponding to a second dose of medicament.

The present invention relates to a device (1) for injection of a product, comprising: a body (2) receiving a hollow injection needle (4) and a container (10) containing the product to be injected; means (5 to 7; 28, 29) for holding the needle in position, means (39, 41, 45) for holding the container (10) in position,; and a piston (11) engaged in the container (10), characterized in that it additionally comprises: first actuating means (42) of means (5 à 7; 28, 29) for holding the needle (4) in position, second actuating means (32) of means (39, 41, 45) for holding the container (10) in position, said first and second actuating means (42, 32) making it possible, at the end of the injection, to respectively release the means (5 à 7; 28, 29) for holding the needle (4) in position before, or simultameously to, the release of the means (39, 41, 45) for holding the container (10) in position, a container support (9) which is mounted slidably on the body (2) and is displaceable relative to the latter in order to perform the injection, means (3, 47, 48) for holding the container support (9) in position, means (49) actuating the release of the means (3, 20, 47, 48) for holding the container support (9) permitting injection in position.
摘要:
A syringe assembly including a needle cannula having a five-beveled point and a needle shield formed of a styrene block poly(ethylene/butylene) thermoplastic elastomer which significantly reduces needle penetration force and may reduce the cycle time for gas sterilization. The multi-beveled needle cannula point includes a primary bevel, a pair of tip bevels and a pair of middle bevels each intermediate the primary bevel and a respective tip bevel, wherein the angles of rotation of the primary bevel and the intermediate bevels are substantially equal resulting in reduced heights of intercepts between the bevels, therby reducing needle penetration force. The needle shield maintains the sharpness of the needle cannula during application, sterilization and removal of the shield and it is believed that the needle shield will also reduce the cycle time of gas sterilization as compared to rubber needle shields and vulcanizate thermoplastic elastomers.
摘要:
A drug delivery device, including a body having a reservoir disposed therein for containing a medicament, the reservoir including a flexible wall; a plunger movable within the body for causing the medicament to be expelled from the reservoir, the plunger having a contact surface that is not affixed to said flexible reservoir wall; a spring biasing the plunger toward the reservoir; and means for selectively maintaining the plunger in a pre-activated position with respect to the reservoir and, upon releasing the plunger from the pre-activated position, for guiding the plunger to move under the force of the spring such that the contact surface of the plunger contacts the flexible reservoir wall to pressurize the reservoir for delivery of the medicament to a patient.
