An add-on logging device (100, 300) mounted to a drug delivery device is turned on when the cap is removed. After a given amount of time in inactivity the sensor means of the add-on device is turned off automatically to save energy. If the user takes a dose of drug this is not detected as the add-on device is only turned on when the cap is removed. According to the present invention a warning message is provided when the cap is re-mounted after the sensor means has been turned off automatically, the warning message indicating to a user that an expelled dose may not have been detected.

A drug delivery device that includes a housing. The housing contains a syringe, and the syringe includes a container containing a liquid medicament. The container includes an aperture at a distal end and through which the liquid medicament can be dispensed. The syringe includes a stopper within the container. The stopper is moveable between a first longitudinal position and a second longitudinal position relative to the container, to cause dispensing of the liquid medicament through the aperture. The syringe includes at least one identifying means identifying the liquid medicament.

A holder with a safety shield for a drug delivery device; the shield obstructing access to a needle of the drug delivery device following use thereof. The safety shield may be actively deployed, in which case the health care worker must perform an action beyond complete depression of the pusher into the body of the drug delivery device to deploy the shield. Alternatively, the safety shield may be deployed passively or automatically, in which case deployment of the shield occurs upon complete depression of the pusher into the body, with no additional action required of the health care worker. The safety shield is springloaded and released to its extended position by a mechanical coupling of a series of position members, including levers, formed on the holder and the drug delivery device.

An injection needle assembly (50) for an injection device, comprising: a) a needle cannula (3) attached to a needle hub (4) and defining a pointed tip at a free end (3a, 3b), and b) a needle cover (10, 10a, 10b) forming an axially extending elongated flexible enclosure accommodating the needle cannula (3). The needle cover (10, 10a, 10b) is configured to axially collapse and become penetrated by the needle cannula (3) when a penetration force is applied to the needle cover. The needle cover (10, 10a, 10b) defines a shaft section (11a) and a bulb section (11b). The shaft section (11a) encircles the needle cannula (3) and extends axially from the needle hub (4) to the bulb section (11b). The shaft section (11a) comprises a collapsible wall area (15) having wall thickness t.sub.1 less than a predefined wall thickness t.sub.1,lim to provide radial deformability for abutting contact with the needle cannula (3). The bulb section (11b) comprises a wall area (17a, 17b) having a wall thickness t.sub.2 being greater than said predefined wall thickness t.sub.1,lim, and further defines a central end wall area (20) having a wall thickness t.sub.3 smaller than the wall thickness t.sub.2. In an initial non-penet-rated state, the needle cover (10, 10a, 10b) assumes a first configuration wherein the wall areas of the bulb section (11b) and the wall areas of the shaft section (11a) are spaced apart from the needle cannula (3).

The present invention suppresses the formation of a pocket in a wall of a puncture route when a dull needle is moved forward along the puncture route. In order to achieve such aim, the invention provides a needle to be inserted into a puncture route extending from skin to a blood vessel under the skin to puncture the blood vessel, wherein: the needle is formed in a tubular shape and has an inclined end face at a tip of the needle, the inclined end face being inclined relative to an axis of the needle, a tip end of the inclined end face defining an unsharp edge; the needle has a flexibility of needle elastic modulus nE=1-900 Nmm as defined by an equation to be set forth below; a material of the needle is a resin; and the needle is manufactured by injection molding using a ring-shaped gate.

An apparatus and method for performing painless bone marrow biopsy that requires only a single procedural pass to the biopsy bone site is disclosed. The biopsy device combines dermatotomy, anesthesia and marrow specimen extraction functionality and inherently aligns the bone drilling site with the site of anesthetic delivery by incorporating a transport channel that may be used for anesthetic delivery, into the biopsy needle used for bone access and bone marrow sample retrieval. The biopsy device also discloses a right angle drill interface and multiple side-access ports for aspiration and anesthetic syringe attachments. A novel syringe/plunger system comprising vacuum tube fitted plungers for quick transfer of marrow specimen sample without requiring a second non-sterile assistant is also disclosed.

Injection device comprising a tubular elongated main body, a needle shield slidably arranged in said main body, a needle shield link slidably connected to said needle shield, a cartridge containing medicament arranged in said main body, a needle connected to said cartridge, a plunger operatively arranged to said cartridge for ejecting said medicament through said needle and arranged on its upper part with a number of outwardly extending stop members, spring means arranged to said plunger for operating said plunger, a dose activating means, a needle shield spring surrounding the needle shield link. The injection device is capable of setting and delivering a certain preset dose.

The present invention relates to an injection needle assembly having opposite distal and proximal ends, and wherein the assembly comprises an injection needle having proximal and distal pointed ends, wherein the distal pointed end is arranged to penetrate a membrane arranged at the proximal end of a medicament container; a tubular needle holder comprising distal engagement means and proximal engagement means; a tubular cap comprising proximal outer engagement means and proximal inner engagement means; a tubular needle cover comprising first engagement means arranged to cooperate with the proximal engagement means, and second engagement means arranged to cooperate with the proximal outer engagement means of the cap; characterized in that said needle cover is arranged to be displaced from a first position wherein the second engagement means and the proximal outer engagement means prevents the needle cover and the needle holder to be axially displaced by a linear displacement, to a second position wherein the needle cover and the needle holder are distally displaced, and wherein the proximal inner engagement means of the cap and the distal engagement means of the needle holder prevents the needle holder to be proximally displaced but allows the needle cover to be distally displaced.

The present invention relates to methods for treating a microbial infection comprising administering a composition comprising one or more antibiotic compounds to the site of the infection by instilling the composition into the tympanostomy tube. A delivery cannula can be used to instill the composition into the tympanostomy tube.
