Storage device and refrigerator
ActiveCN105526769ASimple structurePromote exchangeLighting and heating apparatusCooling fluid circulationEngineeringRefrigerated temperature
The invention relates to a storage device and a refrigerator. The storage device comprises a drawer, a sealing device, a moisturizing module and a moisture adjustment device, wherein the moisturizing module is arranged at the sealing device and is used for improving or retaining moisture in a storage space; the moisture adjustment device controllably or operably changes the size of a gap between a moisturizing cover and the drawer so as to be matched with the moisturizing module to adjust the moisture in the storage space. Thus, according to the storage device, as the size of the gap between the moisturizing cover and the drawer is changed, the moisture adjustment range is large, and the structure of the storage device is simplified. When no gap exists between the moisturizing cover and the drawer, the inner part of the storage device retains the moisture corresponding to the fixed moisture permeable threshold value of the moisturizing module, and excessively high moisture is avoided. The invention further relates to the refrigerator which comprises the storage device and a box body, wherein at least one storage room is limited in the box body. The storage device can be taken out to be put in any storage room so as to provide the moisture-adjustable storage space for the refrigerator.

The invention discloses a nursing teaching intravenous injection-based liquid flow rate display device, which comprises a mounting bracket and an infusion apparatus, the infusion apparatus comprises a drip bottle, the bottom of the drip bottle is communicated with a hose, the upper part of the hose is provided with a drip chamber, and the top of the mounting bracket is provided with a hook for hanging the drip bottle. The upper portion of the installation support is provided with an amplification display assembly used for measuring the flow velocity of liquid, a display belt is connected between the two rotating wheels, the surface of the display belt is provided with a plurality of projection areas, and the projection areas can be used for receiving refraction light spots of a laser transmitter. By means of the arranged amplification display assembly, when the liquid level of the drip chamber changes, refracted light rays generated by the laser transmitter can form light spots on a projection area and move up and down, and within a certain time, the flow speed of intravenous injection at the moment can be visually obtained through the change of the up-down distance of the light spots.
