The present invention relates to a drug delivery device comprising a dose setting member (70) for setting user variable doses of a medicament and a display for indicating the dose set by the dose setting member (70). The display comprises a number wheel (100), which is rotationally coupled to the dose setting member (70) and is provided with a series of markings on its outer circumference, and at least one prism (90) deviating the image of the markings of the number wheel (100), e.g. by 90°.

The present disclosure is generally directed to a drive mechanism for use in a drug delivery device having a cylindrical cartridge, i.e. a handheld injection device for selecting and dispensing a number of user variable doses of a medicament. The drive mechanism includes a base element, a toothed piston rod, which is guided within and movable relative to the base portion, and a drive gear having a pinion, which is rotatably held in the base element and in meshed engagement with the toothed piston rod. The toothed piston rod includes multiple rigid rod pieces which are connected by hinges. The rigid rod pieces comprise a flat plate provided with a straight toothed rack.

The present disclosure is directed to a window element and a drug delivery device, like a pen-type injector, that provides for administration by injection of medicinal products from a multidose cartridge. The drug delivery device may comprise a housing, a dose setting member, a dial, a drive member, a clutch and/or a clicker. The window element comprises a first member with a window and being made from a rigid material, a second member and a third member, each made from an elastically deformable material and being attached to the first member.

Disclosed herein is an immersive distraction apparatus including an attachment portion including an engagement element and a front plate having two cut outs fitting lenses therein and a base portion coupled with the attachment portion having a display aperture sized to receive a device. The immersive distraction apparatus mountable on a surgical head frame using one or more connectors such that an immersive distraction therapy can be provided to a patient undergoing surgery via a virtual reality environment.

The disclosure is directed to a drive mechanism for use in a drug delivery device having a cartridge, the mechanism comprising a base element, a toothed piston rod movable from a first retracted position corresponding to a full cartridge to a second extended position corresponding to an empty cartridge, wherein the piston rod is guided within and movable relative to the base portion, and a drive gear having a pinion, which is rotatably held in the base element and in meshed engagement with the toothed piston rod, wherein the toothed piston rod comprises multiple rigid rod pieces which are connected by hinges, and a drive spring, which is fixed to the base element with one end and fixed to the drive gear with another end and which exerts a force or torque to the drive gear for rotating the drive gear relative to the base element, which rotation results in a movement of the toothed piston rod. The drive spring is charged during manufacture or assembly, wherein the energy stored in the drive spring is sufficient to move the piston rod (from the first to the second position. The disclosure is also directed to a drug delivery device.

A device for delivering a fluid includes a housing defining an interior space and having a bottom surface configured for contacting a patient. The bottom surface defines a needle opening. The device also includes a reservoir disposed within the interior space of the housing for containing a fluid therein, a needle carrier disposed within the housing, and an injection needle supported by the needle carrier and defining a lumen. The lumen of the injection needle is configured to be placed in fluid communication with the reservoir. The injection needle is transitionable from an initial position in which the injection needle is disposed within the housing, to a use position in which the injection needle extends through the needle opening, and a substantially shielded position in which the injection needle is disposed within the housing and the lumen of the needle is blocked by a portion of the housing.

There is provided a dose counter assembly for use with a medicament dispenser, the dose counter assembly comprising: a) a units dose display means comprising a first count indicia and one or more driver teeth; b) a tens dose display means comprising a second count indicia; and c) a driver, wherein the first count indicia and second count indicia align at a common viewing area to collectively display a count sequence.

Airway adapters, suction catheter systems, and methods of using the same are described herein. An exemplary airway adapter assembly may comprise a connector body portion having a first end and a second end, an elongate cavity having an axial center can be defined between the first and the second end, and a valve can be coupled to the second end of the connector body. The exemplary airway adapter assembly may also comprise a ventilation base member comprising a tubular portion coupled to the second end of the connector body portion and ventilator port. The ventilator port may comprises a conduit having a first conduit end and a second conduit end, and the first conduit end may be coupled to the tubular portion through an articulable connection. An exemplary closed suction catheter system may comprise a suction control valve assembly and a closed suction catheter sheath.

A check valve includes an upper housing defining an inlet of the check valve, and a lower housing having a seating portion and defining an outlet of the check valve. The check valve further includes a chamber interposed between and defined by the upper and lower housings for fluidly connecting the inlet and the outlet, and a flexible diaphragm mounted in the chamber. The flexible diaphragm selectively permits fluid flow in a first direction, and prevents fluid backflow in a second direction opposite to the first direction. The flexible diaphragm includes a color changing material, and when the flexible diaphragm is seated on the seating portion and bent due to force of the fluid flowing in the first direction, the flexible diaphragm exhibits a color change.
