A tool for use on safety showers may include a funnel, a drain system, a base, and a height adjustment mechanism. The funnel has an interior with a width wider than a showerhead of the safety shower, so that a showerhead may fit within or seal against the interior of the funnel. The drain system connected to conduct a flow from the funnel. The base supports the drain system and the funnel and may be placed on a floor beneath the showerhead, and the height adjustment mechanism may be coupled to control a height of the funnel and control sealing pressure that the funnel applies to a showerhead.

Systems and methods of treating meibomian and sebaceous gland dysfunction. The methods include reducing oxygen concentration in the environment of one or more dysfunctional meibomian and sebaceous glands, thereby restoring a hypoxic status of one or more dysfunctional meibomian and sebaceous glands. The reducing of the oxygen concentration is accomplished by restricting blood flow to the one or more dysfunctional meibomian and sebaceous glands and the environment of one or more dysfunctional meibomian sebaceous glands. The restricting of the blood flow is accomplished by contracting or closing one or more blood vessels around the one or more dysfunctional meibomian or sebaceous glands. The methods also include giving local or systemic drugs that lead to the generation of hypoxia-inducible factors in one or more dysfunctional meibomian and sebaceous glands.

Disclosed herein is an improved eyelid care appliance and method of using such appliance for preventing and treating blepharitis and mammalian meibomian gland dysfunction caused by gland obstruction. The method and apparatus of the invention enable restoration and maintenance of eyelid hygiene and the natural flow of secretions from the meibomian glands. A preferred embodiment of the apparatus comprises an oscillating spongehead affixed to the distal end of the eyelid care appliance that is equipped with a video camera, near field communications link, and a display, thereby enabling a user to fly the spongehead onto an eyelid margin for self-administered cleaning of the user's eyelid margins. The spongehead can be impregnated with topical pharmacologic or cleansing agents to better facilitate cleaning and therapeutic efficacy.

For allowing an access to an eye during a rinsing process it is suggested to configure an eye opening device in such a way that the eye opening device comprises two wing-like spreading elements for pulling the upper eyelid and the lower eyelid of the eye apart so as to support the opening of the eye during a rinsing process, wherein two access gaps are formed laterally between the two wing-like spreading elements of the eye opening device.

The shower head nozzle as disclosed herein includes a quick-connect coupling for selectively attaching the nozzle to a downwardly extending conduit or tube for directing tested water through a test unit and into a bucket or drain, wherein the test unit may include a flow meter for measuring real-time water flow rate and a temperature sensor for measuring real-time water temperature dispensed from the shower head, thereby reducing the testing time, more accurately determining flow-rate and water temperature, and decreasing the amount of waste water.
