  • Publication number: 20070211212
    Abstract: A method for sensing the state of an eye of a subject comprises measuring light reflected from an ocular surface and comparing the measured light to a reference. A method for treating an eye of a subject comprises sensing the state of the eye as described above, and controlling whether a substance is delivered to the eye whereby the substance is so delivered only when the eye is sensed to be open. A device for sensing the state of an eye comprises a light source that directs light to an ocular surface of a subject, and a sensor for measuring light reflected from the ocular surface. An apparatus for treating an eye of a subject comprises a device for sensing the state of an eye as described above, an applicator for delivering a substance to the eye, and a control system that permits delivery of the substance when the sensing device detects that the eye is open but prevents delivery of the substance when the sensing device detects that the eye is closed.

  • Publication number: 20040181195
    Abstract: Pressurisable container for storing and ejecting liquid, the container comprising a) a front wall having or surrounding a cavity corresponding to the form of an open vessel, b) an opening in the front wall adapted for ejection of the liquid from the container, said opening defining a container axis, c) optionally a sealing over the opening adapted for temporary use, and d) a rear wall closing and sealing the open part of the front wall vessel to confine a space for the liquid in the container, the rear wall running at least partially perpendicular to the container axis and being displaceable or deformable for movement towards the opening to pressurize the container liquid. The front wall is substantially rigid in relation to the rear wall, the rear wall before pressurizing the container is substantially flat or substantially single-curved and the rear wall is deformable under stretching to substantially fill out the container cavity.

  • Patent number: 5709659
    Abstract: The present invention is directed to a drug containing non-reusable syringe having a hollow plunger rod provided with a rupture line for permanently detaching its rear part which can be engaged with the needle holder to perform a radial motion that breaks the needle which thereafter is received by a cavity in the rear part of the detached plunger rod. The rear part of the plunger rod can also be attached to the needle holder to protect the user from accidental needle sticks.

  • Patent number: 4411358
    Abstract: The invention relates to a package protecting its contents from the influence of light, microbial contamination and gas transport in either direction but which makes possible a visual control of the contents before the package is used.According to the invention, the package is made of a light-proof outer bag (1) and a light permeable inner bag (3) arranged inside the outer bag. The outer bag (1) and the inner bag (3) are each sealed at one of their ends (2,4) and are bonded around their periphery (6) close to their other end, and the two bags extend over this bond and are then commonly joined and sealed. By opening one of the end seals in the outer bag (1), the inner bag (3) can be turned out of the outer bag, and the contents (5) of the package can be observed visually through the inner bag.The package of the invention is especially suitable for storage of preparations for parenteral administration and especially infusion solutions intended to be given intravenously.
