Abstract: The present invention relates to the field of medical devices, and relates to an electrophysiological test method for an auditory brainstem implant (ABI) and a recording electrode used therein. According to the method of the present invention, there is no need to subcutaneously place an additional recording electrode for a patient, which simplifies preoperative preparation. Moreover, the method has advantages of a high signal-to-noise ratio, a fast response speed, a short recording time, and a large anti-interference ability, thus can effectively improve efficiency of intraoperative electrode test. The method is suitable for use in an auditory brainstem implantation surgery. Besides, the present invention enables the auditory brainstem implantation to be located more accurately, thereby expanding a scope of application.

Abstract: The present invention relates to the field of hemodialysis and peritoneal dialysis, in particular to a fat emulsion dialysate, and preparation method and the use thereof. Provided in the present invention is a fat emulsion dialysate, comprising a long-chain fat emulsion oil, a medium-chain triglyceride, an anti-oxidant, sodium oleate, glycerin, phospholipid, and a solvent. Compared with traditional dialysis, the fat emulsion dialysate provided by the present invention has a better advantage for protein-bound toxin removal. In addition, the fat emulsion dialysate not only has a simple preparation method and a low cost, but also has good stability and safety, and remains stable at room temperature for 14 days without obvious precipitation. Thus, the fat emulsion dialysate can become a hemodialysis dialysate or peritoneal dialysate with broad application prospects, and has good industrialization prospects.

Abstract: Disclosed is a force applying device for orthodontic treatment being elastically expandable and configured to generate a restoring force as an orthodontic force for an orthodontic treatment when compressed. The force applying device comprises a first element and a second element capable of moving relative to each other along a first axis. The force applying device for orthodontic treatment is compressed when the first and second elements move towards each other along the first axis. A first arm extends laterally from a first end of the first element away from the second element. A first connecting part of a first connector is fitted over the first arm. A second connecting part of the first connector is to be fitted over a button fixed on a first jaw to connect the first element to the first jaw. Both the first and the second connecting parts are toroidal in shape.
