Abstract: An optical system (31) for analysing biological processes comprising: a biological process vessel (33) comprising a chamber and an optical interface element (34) for optically coupling the chamber to an optical emitter, a wavelength discrimination component, and an optical detector when a biological process fluid in the chamber is being analysed, the optical interface element being configured to couple light in the mid-infrared range; an optical emitter (351) configured to emit light in the mid-infrared range; an optical detector (353) configured to detect light in the mid-infrared range; a wavelength discrimination component (352); an alignment component (42) for aligning the optical emitter, optical detector, and wavelength discrimination component with the optical interface element; and a processor (354) configured to: receive outputs from the optical detector; and process the received outputs from the optical detector to provide an indication of the constituents of a biological process fluid in the chambe

Abstract: The present disclosure provides an apparatus including a lens housing coupled to a lens assembly, a first lens disposed in a first end of the lens housing, a lens holder disposed in a second end of the lens housing, a lens aligner coupled to the lens assembly, and an optical element. The optical element is insertable laterally into the lens assembly to adjust a transverse position of the first lens and the second lens based on a thickness of the optical element to align a first axis of the first lens and the second lens to a second axis of a third lens positioned in the lens assembly for imaging an eye.

Abstract: The present disclosure provides an eye-imaging training apparatus including an actuator to articulate one or more movable eyeball members. The eye-imaging training apparatus provides a caregiver a training tool for practicing various eye-imaging techniques that simulate or mimic natural and animal-like eye movement. For example, the eye-imaging training apparatus may include an eyeball member that can move in multiple directions to simulate human-like eye movement. The eye-imaging training apparatus can train a caregiver to practice, for example, aligning an eye-imaging camera, calibrating the eye-imaging camera (e.g., determining the desired optical parameters), and retracting eyelids for eye-imaging. The present disclosure is also related to systems and methods for eye imaging using an eye-imaging training apparatus.

Abstract: A foam-layered dressing, a method for making the same, a method for applying the same, a foam composition, and a foam layer composition produced by a process are provided. The dressing may have two or more foam layers. To this end, a slurry may be added to a first foam layer. The slurry and the first foam layer may be cured and dried. As a result, the slurry may undergo a chemical change and may form a second foam layer. The first foam layer and the second foam layer may be separated by an interface. The foam layers and the interface layer may have a moisture/vapor transmission rate which may assist in healing a specific type of wound.
