Abstract: Present invention relates to pneumatic connector assembly for pneumatically coupling a pressure source and an inflatable mattress or controlling the inflation and/or deflation of said inflatable mattress.

Abstract: An indicator device includes a casing having rearward projecting elements from which coupling hooks extend. The device includes a downwardly facing window as well as two forwardly or upwardly extending windows. The device includes lights or lamps disposed adjacent the windows for generating status and/or warning signals. The device can be hooked onto a support such as a footboard of a hospital bed or placed on a floor with a window exposed. The window is able to direct light from the lighting elements to a surface such as a floor or footboard or other surface. This assists in a caregiver seeing light emanating from the device even when this is covered.

Abstract: A luminometer comprises a body which is formed with a bore for receiving a sample container and a cavity communicating with the lower end of the bore. A control device having a part-circumferential ramp is rotatable within the cavity for displacing the sample container along the bore to and from a test position in which the sample container is exposed to a photo-multiplier device. The control device is rotated by a cap which is coupled to the control device and which covers the upper end of the bore in light-tight manner as the control device lowers the sample container to the test position.

Abstract: An injection system for use with a luminometer, which includes a carrier movable between a liquid loading station and a liquid dispensing station and a dispenser assembly mounted on the carrier and including an injector needle arranged, when at the liquid loading station, to pass through an aperture in a part of the luminometer aligned with a test sample container therein, the container being in a test chamber with which a photomultiplier device communicates. The system also includes a sealing arrangement which prevents light from passing through the aperture in the luminometer, both when the needle extends through the aperture and when the needle has been withdrawn from the aperture.
