Abstract: A fetal Doppler (10) and a detection method, which relate to the technical field of medical devices. The fetal Doppler (10) comprises a housing (1, a fetal detection unit (20) and a maternal parameter detection unit (30), wherein the fetal detection unit (20) and the maternal parameter detection unit (30) are respectively used for collecting fetal physiological data and maternal physiological data; a controller (7) is arranged in an internal cavity of the housing (1); and the controller (7) is used for analyzing the collected fetal physiological data and maternal physiological data, so as to obtain a fetal heart rate and a maternal parameter. The same fetal Doppler (10) is used, such that the instrument cost is reduced; and maternal and fetal parameters can be acquired at the same time by directly using the same fetal Doppler (10), such that an instrument structure is simplified, and the detection efficiency of the maternal and fetal parameters is improved.

Abstract: The disclosure provides a probe holding table and a medical equipment. The probe holding table comprises a faceplate and a fixing plate for supporting the faceplate. The faceplate is rotatably connected to the fixing plate. A plurality of probe placement units for installing probes are disposed on the faceplate, and each of the probe placement units is in electrical communication with an external power. The user may turn the faceplate to take the probes on the corresponding position, in particular, when more probes need to be used, the structure of the probe holding table is simpler than the normal fixed table, and easier to take the probes. Therefore, the medical equipment adopted the above probe holding table provides with the above advantages.

Abstract: A catalyst that includes cerium oxide having a fluorite lattice structure is provided. The cerium oxide includes cerium atoms in mixed valence states of Ce3+/Ce4+, in which the ratio of Ce3+/(Ce3++Ce4+) in the lattice ranges from 40% to 90% at 20° C. The valence states Ce3+ and Ce4+ are reversible in reduction and oxidation reactions, and the cerium oxide maintains catalytic ability at temperatures at least up to 450° C.

Abstract: A multi-function clamp for veterinarian, mainly includes upper clip and lower clip; the clamp body is composed by upper clip, lower clip, bolt and torsional spring, wherein the foresaid clamp body installed with connection assembly that has connecting lead wires, and the connection assembly has several installation sections coordinates with the lead wire plug. By adopting the compatibility design, the multi-function clamp for veterinarian could apply to wider areas, a pet clinic equipped with the multi-function clamp for veterinarian is applicable even using the probe-type lead wires, the banana plug lead wires, the snap-type lead wires and the clip-type lead wires simultaneously, which greatly decreases the procurement cost for equipment and accessories, and easier to be operated. Furthermore, by adopting the anti-slip design, the multi-function clamp for veterinarian will improve remarkably for the matter the clamp drops off from the operators or the animal skins, which saves time in operation.
