摘要:
An assembly for use with a syringe having a barrel and a needle includes a sealing element surrounding and positioned over at least a portion of the distal end of the syringe. An adapter at least partially surrounds the sealing element and is positioned over the distal end of the syringe. The adapter has a first skin contacting surface positioned at a distal end thereof. At least a portion of the first skin contacting surface extends generally parallel to at least a terminal end of the needle. The adapter also has a second skin contacting surface positioned proximally relative to the terminal end of the needle and at an angle to the first skin contacting surface. A needle shield at least partially surrounds and is removably positioned over at least one of the adapter, the sealing element and the syringe barrel.

摘要:
An intradermal injection adapter includes a body having a longitudinal axis and a central portion located distally relative to the body along the longitudinal axis. The central portion has a cannula channel therethrough extending generally parallel to the longitudinal axis. A cannula within the cannula channel has a sharpened tip for injection into a patient and a sharpened opposite proximal end for injection into a pen injector. A distal protrusion has a first skin contacting surface extending generally parallel to the longitudinal axis. The first skin contacting surface is spaced from the cannula such that a distal portion of the cannula extends generally parallel to the first skin contacting surface.

摘要:
A drug delivery device having a housing containing a gas generator controlled by an electronic controller. The gas generator generates gas into a reciprocable chamber, whereby reciprocation of the chamber causes a lever to reciprocate a pawl, and this action causes a ratchet to undergo incremental advancement. The device may also be provided with manual control for delivering a bolus dose of drug when necessary.
摘要:
The device infuses a compound subcutaneously or intradermally over an extended period of time. The delivery is from a conventional prefilled syringe with a staked cannula with the device adhered to the injection site and the syringe positioned substantially parallel to the injection site. The cannula is formed by a mechanism integral to the device to provide the cannula distal section substantially perpendicular to the syringe axis. The compound delivery is based on springs or other mechanisms. The approach offers a low cost mechanical system for the infusion of high volume, viscous compounds. The activation of the patch infuser required a few simple steps by the user. A single lever is used to trigger all device functions.

摘要:
A syringe comprises a barrel containing an internal cylindrical body containing a liquid and communicating with a delivery needle. The needle is covered before use by a removable sheath, and after the sheath is removed, the needle is concealed by a displaceable sleeve. In use the sleeve is pressed against the skin by applying pressure while holding the barrel. The sleeve is thereby retracted into the barrel allowing the needle to penetrate the skin. The movement of the sleeve also activates a gas generator which expels the liquid from the needle. When delivery is complete and the syringe is taken from the skin, a coil spring moves the sleeve back to the starting position again concealing the needle. The coil spring is torsionally biased before use and causes a rotational movement of the sleeve relative to the barrel when the sleeve moves into and out of the barrel. This rotational movement engages a locking mechanism which prevents further movement of the sleeve and thereby permanently conceals the needle.
摘要:
A spike for facilitating the introduction of liquid under pressure into a container containing a substance is provided which includes an elongate spike shaft having a spike side wall, a longitudinal axis, a distal end and a proximally located end portion, where the distal end has a sharp, pointed tip. An introduction channel is located within the spike shaft for receiving liquid into the container where a portion of the introduction channel is angled to cause liquid to travel out of the introduction channel in a direction non-parallel to the longitudinal axis of the spike shaft. An extraction channel may be included within the spike shaft for removing liquid from the container, where the extraction channel extends through the elongate spike shaft towards the proximally located end portion.
