A drug delivery device capable of working in at least two different modes which includes a dose injection mode and a set-up mode. The drug delivery device automatically changes from the dose injection mode to the set-up mode and vice versa in accordance with the detection of the cover by a cover detection switch. In the dose injection mode doses can be set and injected; in the set-up mode various parameters assisting the use of the drug delivery device can be set. This setting is preferably done by selecting the parameters from a menu, also in this mode historical data stored in the device can be viewed.

Injection device with cap

A limiting mechanism which prevents the setting of a dose, which exceeds the amount of liquid left in a cartridge of an injection device, is disclosed. The injection device is the type where a dose is set by rotating a dose setting member relative to a driver and away from a fixed stop in the injection device. The dose setting member interfaces the driver such that the dose setting member can be rotated in one direction without rotating the driver. The dose is injected by rotating back the dose setting member which during the backward rotation carries the driver with it. Rotating the driver causes the piston rod to move forward inside the cartridge and expel some of the liquid contained in the cartridge. The driver is provided with a track having a length which is related to the total amount of liquid in the cartridge and which track is engaged by a track follower coupled to the dose setting member to follow rotation of this dose setting member. Each time a dose is set and injected, the track follower moves further into the track. When the track follower reaches the end of the track the dose setting member can not be rotated further, and a dose larger than the remaining liquid in the cartridge cannot be set.

Dose setting limiter

Described is a dose setting limiter for medical injectors of the type having a housing accommodating an ampoule-containing medicine sufficient for a number of dosed injections, a rotary dose setting knob, which is rotational relative to the housing and by which doses may be set by rotating the dose setting knob and an injection button which, when activated, administers the set dose. The dose setting limiter includes a stationary first part connected to the housing, and a second part fitted over the rotary dose setting knob, the second part being able to rotate together with the dose setting knob when setting up a dose and the second part being rotational relative to the first part. A third part is placed between the first part and the second part, the third part having means cooperating with means on the second part for limiting the dose setting.

A flexible piston rod for use in cylinder ampoules comprises a tape shaped body (,) which is along its length provided with supporters (,) projecting from at least one side of the tape. The tape (,) has a width and the supporters a length so that sides of the tape and the free ends of the supporters abuts the inner wall of the ampoule (,) in at least three positions along the inner perimeter of the ampoule (,) and not all the abutment points lies on the same half of the circular cross section but are typically displaced about 120&deg; from each other. The piston rod is moved by a gear engaging a rack (,) on the tape either on the side not carrying supporters or at the edge of the tape on the side carrying supporters.

Syringe having a flexible piston rod

Kit for storage and mixing of agents of which at least one is liquid

The present invention relates to injection syringes comprising a housing accommodating an ampoule containing medicine sufficient for a number of dosed injections. The syringe has a dose setting mechanism by which doses may be set by rotating a dose setting element relative to the housing and the dose set is indicated on a scale. The scale is formed as a clock dial having a first part secured to the housing and a second part which is rotatable relative to the first part and which is coupled to the dose setting element, one of parts carries the scale and the other carries an indicating member indicating a point on the scale. The angular distance between the divisions of the scale corresponds to the minute divisions on an ordinary clock. Holes are provided along the scale which holes can receive a pin forming a stop which cannot be passed by the indicating member.

Dose display for an injection syringe

A blood sampler comprises a small chamber having a stiletto mounted air-tightly through a flexible top wall with a pointed end of the stiletto positioned inside the chamber opposite an opening in the bottom part of the chamber. The sampler is designed to be mounted in a tool which compresses the chamber by pressing the flexible top wall against the bottom of the chamber. Further, the tool has means for imparting an impact on a blunt outer end of the stiletto to drive the stiletto further through the top wall to make its sharp end protrude through the opening in the bottom part into the skin to which the sampler may be attached by an adhesive. When the sampler is ejected from the tool, it regains its original shape, providing in the chamber a vacuum for sucking blood from the perforated skin into this chamber.
