摘要:
A fluid dispensing device is provided for dispensing a measured amount of fluid into a living organism. The device has a needle having a first end and a second end. The needle is adapted for interfacing, on the first end, with a septum of a flexible hollow membrane, and at a second end thereof, for subcutaneously inserting into a living organism. The needle is guided by a guide to permit an injection into the living organism at a substantially non-orthogonal angle with respect to a surface of the living organism. The first and second ends of the needle pierce their respective piercing surface while translating together in a common direction. In other embodiments, the dispensing device includes a main housing, a flexible fluid reservoir, an injection assembly and a trigger mechanism. The main housing houses the operative components of the device.

An apparatus is disclosed for storing and changing needles for connection with a medicament delivery device, comprising an inner housing, a reservoir disposed within the inner housing, and a needle holder disposed within the inner housing, for fluidly connecting a medicament container of the medicament delivery device with the reservoir. The apparatus also includes a plurality of patient needles displaceably disposed on the needle holder, and an outer housing displaceably disposed about the inner housing and providing a user interface to individually select one of the plurality of patient needles, connect the selected needle with the reservoir, expose the selected needle outside of the apparatus for injection, and store the selected needle.
摘要:
An infusion set has a retraction dial that can be removably assembled with the infusion set and access a threaded needle hub contained therein such that the dial can be used to advance or retract a needle hub and an inserted needle to a more precisely controlled insertion depth to deliver insulin or other medicament intradermally (i.e. to the upper 3 mm of skin surface). Position of the inserted needle can be maintained by providing a separated and isolated needle hub, main base and main hub of the infusion set that can isolate the inserted needle from external forces such that the needle can be maintained at a depth to deliver content to the upper 3 mm of skin surface during normal use.

An infusion set (201) includes a base (221) and a flexible catheter (242) movable from a first catheter position disposed substantially entirely within the base (221) to a second catheter position in which a free end of the catheter (242) is disposed externally of the base (221). An introducer needle (234) is located within the catheter (242) and is movable between a first introducer needle position disposed substantially entirely within the base (221) and a second introducer needle position in which a free end of the introducer needle (234) is disposed externally of the base (221). A torsion spring (281) is activated to move the catheter (242) from the first to the second catheter position and the introducer needle (234) from the first to the second introducer needle position to facilitate insertion of the catheter (242). The introducer needle (234) is thereafter moved by the torsion spring (281) back to the first introducer needle position to store the introducer needle (234) within the base (221) with the free end of the catheter (242) remaining disposed externally of the base (221).

A dual-chambered drug delivery device (201) includes a first chamber (205) in which a medicament is stored. A dose setting member (213) is rotated to set a medicament dose. The dose setting member (213) being rotatable to set the medicament dose. The dose setting member (213) is not axially moveable. A second chamber (221) is in fluid communication with the first chamber (205). The medicament dose is transferred to the second chamber (221) from the first chamber (205) prior to injecting the medicament dose. A needle (203) communicates with the second chamber (221) to inject the medicament dose into an injection site.

A drug delivery device includes a cartridge (211) for storing a medicament and a needle (203) communicating with the cartridge (211) for injecting a medicament dose. A rack (241) is movably disposed in the cartridge (211) and is engageable with a stopper (213) for expelling the medicament dose from the cartridge (211). A lever assembly (231) has a lever arm (233) connected to a lever gear (230). The lever gear (232) is engaged with the rack (241) such that rotation of the lever arm (233) rotates the lever gear (232) during injection of the medicament dose, thereby moving the rack (241) and stopper (213) through the cartridge (211) to deliver the medicament dose.

摘要:
A robotic end effector for collecting frozen aliquots from an array of frozen samples in a plurality of containers has a coring bit for taking frozen sample cores from the frozen samples and a frozen sample core extraction system adapted to extract frozen sample cores from the frozen samples. A fill level detection system is adapted to detect the positions of the surfaces of the frozen samples. A processor is adapted to receive signals from the fill level detection system and use the signals and information concerning operation of the frozen sample core extraction system to determine at least one of the following: (a) the amount of material contained in a frozen sample core obtained by the coring bit; and (b) the number of frozen sample cores needed from a particular frozen sample to obtain a predetermined amount of material from that frozen sample.
摘要:
An apparatus is disclosed for storing and changing needles for a medicament delivery device having a medicament container, including a fixed mount for connecting the apparatus with the medicament delivery device, a needle holder displaceable along a circuitous path and connecting a plurality of needles displaceably disposed thereon, and a guide member for guiding displacement of the needle holder, the guide member being disposed about the fixed mount. The apparatus also includes a user interface rotatably disposed about the fixed mount and having at least one internal engaging structure for displacing the needle holder along the circuitous path.
摘要:
An apparatus is disclosed for storing and dispensing pen needles for an injection device, including a case having dispensing and storage ends for dispensing and storing a plurality of pen needles and a plurality of needle cover units, each pen needle having a patient end and a hub for connection to the injection device, and each needle cover unit having a needle-covering portion for covering a patient end and a hub-covering portion for covering a hub. A needle-covering portion covering the needle of one pen needle is coupled with a hub-covering portion covering a hub of another pen needle. Prior to use, a hub-covering portion covering the hub of a pen needle is exposed to an outside at the dispensing end of the case, and subsequent to use, the pen needle is stored in the storage end of the case.
