Abstract: To specify, collect, and manage data that matches a usage purpose of a user with high efficiency among enormous medical data. In a case where prescribed medical data is data worthy of evaluation for a user who manipulates a user terminal, a communication unit receives an evaluation result. A database generation unit selectively reads the medical data the evaluation result of which has been received by the communication unit among the medical data accumulated in a medical information storage, and stores the medical data in the storage unit. This processing is repeated every time when an evaluation result is received to generate a database.

Abstract: An apparatus for treating tinnitus through stimulating multiple acupoints with a multi-electrode electric pulse. A control terminal controls a first MCU micro-control module and the second MCU micro-control module to allow the second MCU micro-control module to output a variety of different pulse signals, and the different pulse signals are respectively output to an electric-pulse output circuit and an electric-pulse conversion circuit. The pulse signal output to the electric-pulse output circuit is a carrier signal. The pulse signal output to the electric-pulse conversion circuit is converted to a modulating wave by the electric-pulse conversion circuit. The modulating wave and the carrier signal are both output to the electrical-pulse output circuit. After a modulation, a transcutaneous electric-pulse stimulation signal is output by an output port, and is transmitted to an electrode sheet attached to the corresponding acupoint on human body through an electrode wire to stimulate the acupoint.

Abstract: Provided is a main unit of a nursing machine, including a sewage bucket accommodating sewage, a water blocking device, a first water tank, a second water tank, a water pump, a first waterway, a second waterway, and a third waterway. The water blocking device includes a labyrinth-type channel communicating with a water storage cavity and a float accommodation cavity, and multiple division boards extending up and down to perform separation to form the labyrinth-type channel. The labyrinth-type channel is located between the water storage cavity and the float accommodation cavity, and communicates between the water storage cavity and the float accommodation cavity. The second water tank is provided with a first water inlet and a first water outlet. The water pump joins the third waterway.

Abstract: The invention discloses an anti-phenacetin monoclonal antibody hybridoma cell strain AD, a preparation method and application thereof, and relates to the technical field of food safety immunodetection. The monoclonal antibody hybridoma cell strain is named monoclonal cell strain AD and the number CGMCC19681. The Phe-BA obtained by the hydrolysis of the reaction product of the phenacetin metabolite acetaminophen and ethyl 4-bromobutyrate is used as the hapten, and the hapten is coupled with the carrier protein to prepare the immunogen Phe-BA-BSA. After the mice were immunized with the immunogen Phe-BA-BSA, they were fused with myeloma cells by PEG method, screened by indirect competitive enzyme-linked immunosorbent assay and subcloned five times to obtain hybridoma cell lines. The monoclonal antibody secreted by the cell line can be made into a phenacetin detection kit, which has good affinity and detection sensitivity for phenacetin, and can be used for immunodetection of phenacetin residues in food.
