摘要:
The present invention relates to an injection needle assembly having opposite distal and proximal ends, and wherein the assembly comprises an injection needle (46) having proximal (48) and distal (50) 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 (40) comprising distal engagement means (44; 70) and proximal engagement means (54); a tubular cap (26) comprising proximal outer engagement means (60; 80) and proximal inner engagement means (36, 38; 72); a tubular needle cover (12) comprising first engagement means (52) arranged to cooperate with the proximal engagement means (54), and second engagement means (58; 78) arranged to cooperate with the proximal outer engagement means (60; 80) of the cap; characterized in that said needle cover is arranged to be displaced from a first position wherein the second engagement means (58; 78) and the proximal outer engagement means (60; 80) 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 (36, 38; 72) of the cap and the distal engagement means (44; 70) of the needle holder prevents the needle holder to be proximally displaced but allows the needle cover to be distally displaced.

A medication delivery pen is provided including a leadscrew having a plurality of threads; a driver coaxially disposed about at least a portion of the leadscrew; a dosing ring non-rotatably disposed on the driver, the dosing ring also being slidable along the driver; and, a dose knob coaxially disposed about the dosing ring. At least one tooth is formed on one of the dose knob and the dosing ring, and at least one groove is formed on the other of the dose knob and the dosing ring, with the groove being formed to receive the tooth. The dosing ring is selectively movable relative to the dose knob from a first position where the tooth and the groove are spaced apart to a second position where the tooth is received within the groove, the dosing ring being rotatable with the dose knob with the dosing ring being in the second position. Incorrect dosage settings of the inventive pen may be easily corrected by a user via a novel dial-back feature that enables the user to reset the dose amount without expelling medication and without having to dial the dose knob to an extended, reset position.

A one-time use device to deliver preservative-free follicle stimulating hormone (FSH) solution is disclosed. The device includes a needle covered by a sliding needle shield, which covers the needle in all modes of the device. The device can be placed into a ready-to-use position in four or fewer user steps. The device has a knob for setting a desired dose of FSH. The knob includes longitudinally spaced elements respectively corresponding to the lock position and the seven or fewer discrete dosing positions. The device locks after one use and cannot be reused thereafter.

摘要:
An injection needle assembly is presented having a tubular needle holder with distal and proximal engagement means, a tubular cap having proximal inner and outer engagement means, a tubular needle cover having a 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. The 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. 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.
