The application relates to the field of medical article storage, and discloses a special storage device for dialysis patients, which comprises a supporting mechanism and a plurality of storage boxes. The plurality of storage boxes are fixed to each other, the supporting mechanism is clamped on the edge of a hospital bed, the plurality of storage boxes are connected with the supporting mechanism, and the supporting mechanism is used for supporting the plurality of storage boxes. The application realizes orderly classified placement and avoids random accumulation of articles.

This invention discloses a high-energy-density hollow piston rod hydraulic accumulator and its working method, belonging to the field of hydraulic energy storage technology. It includes a cylindrical cylinder and a gas cylinder. The bottom of the cylinder has a liquid chamber end cap sealing the bottom end, and the top of the cylinder has a gas chamber end cap sealing the top end. A piston is located in the middle of the cylinder, and a hollow piston rod penetrates the gas chamber end cap. The rodless chamber in the cylinder, separated by the piston, is a liquid chamber filled with hydraulic oil. The rodless chamber in the cylinder, separated by the piston, is a gas chamber. A gas chamber port is located on the cylinder side wall near the gas chamber end cap, and the gas chamber port is connected to the gas cylinder via a high-pressure pipe. The liquid chamber end cap has a liquid chamber oil inlet communicating with the liquid chamber. The hollow piston rod is entirely sealed, with a through hole on the side wall near the piston connecting to the inner cavity of the hollow piston rod. This increases the initial volume of the gas chamber, improves the energy storage density of the accumulator, and simultaneously reduces the weight of the hollow piston rod itself, thus reducing production costs.

This utility model relates to a multi-specification circular paper cutter, comprising a cutter body, which consists of a base, a transparent turntable, and a cutting head assembly. The cutting head assembly is mounted on the transparent turntable, which is mounted on the base. The base presses firmly onto the paper. By rotating the transparent turntable, the cutting head assembly performs the circular cutting operation on the paper. This multi-specification circular paper cutter features a simple and reasonable structure, ease of use, and stable operation.
