Abstract: A reagent reaction determination method and device applied to a test tube, a computer-readable storage medium and a test tube, wherein, the reagent reaction determination method comprises: outputting a brightness control signal to the light-incident component to control the light-incident component to emit the RGB light, and to adjust the brightness control signal according to a preset step length, so as to adjust the brightness of the RGB light; detecting brightness variations of the light derived by the light-emergent component to generate an electrical signal detection value; perform an interpolation calculation on the present brightness control signal to obtain an estimated value of the brightness control signal when the electrical signal detection value is less than a preset threshold, and determining a reaction result in the reagent reaction chamber according to the estimated value of the brightness control signal. The reagent reaction determination device can greatly improve the user experience.

Abstract: A holder serves as a removable accessory to a stimulator unit chassis or cabinet, or other device. It can function as an integral part of the device that closely fits over the top of the device, to provide a support for a hand-held tool associated with the device, e.g., a bipolar probe with widely spaced electrodes. The holder, which may be constructed to be of one piece, is configured to be easily removed from the device to facilitate cleaning of the holder and/or to facilitate packing of the stimulator unit (or other device) for shipping purposes, e.g., in case of device repairs, etc. In other embodiments, the holder may associate a tray or box for storing a variety of items with a host device on which the holder is mounted.
