Orthodontic device for activating the growth of the lower jaw for use in combination with fixed orthodontic appliances, comprising two plastic bodies, each provided with at least one counter-surface corresponding to the chewing surface of molars in the upper jaw, and at least one counter-surface corresponding to the chewing surface of molars in the lower jaw, and further attaching means for attaching to the upper jaw, wherein each plastic body comprises at least two parts which can be displaced and fixed relative to each other substantially parallel to the longitudinal direction of the respective counter-surfaces, wherein each part is provided with at least one of said counter-surfaces.

The invention relates to a flow injection microscope raman spectrum device for water pollutant detection and a detection method and belongs to the technical field of monitoring for the water environmental pollution. The device comprises a sample feeding module, a power supply module, an optical collecting module, a detecting analysis module, a result display output module and a positioning and wireless communication module, wherein the power supply module is used for supplying electric energy to the whole detection device and performing power supply management; the sample feeding module is used for conveying a to-be-detected water sample into a micro-fluidic chip through a micro-pump and a filtering device; the accurate positioning and focusing between the micro-fluidic chip and a microscope raman module are realized by adjusting the position of a displacement adjusting platform; a raman scattered signal of the to-be-detected water sample is collected by the optical collecting module, is subjected to photovoltaic conversion and then is sent to the detecting analysis module for testing the ingredients and contents of the pollutants in the to-be-detected water sample; a detection result is output and displayed on a display terminal; the position of a to-be-detected water sample point and the condition of the water pollution are transmitted to a superior monitoring center through the positioning and wireless communication module, so that the remote real-time monitoring is realized. The flow injection microscope raman spectrum device provided by the invention is compact in structure, is convenient in operation and accurate in detection, and can be used for realizing quick online detection on the water quality of river, lack, urban sewage, and the like.

The invention discloses a scalpel placement rack and belongs to the technical field of medical supplies. The scalpel placement rack comprises a fixed rack, a placement layer and multiple partition parts, wherein the placement layer is obliquely and fixedly mounted in the fixed rack, the multiple partition parts are arranged below the placement layer and arranged at equal intervals, multiple slits are formed in the placement layer, and partitions of the partition parts are arranged in the slits. Each partition part comprises a partition, a support frame and a movable frame, the partition is mounted below the slit of the placement layer and on one side of the movable frame, the support frame is mounted below the movable frame, and the partition and the movable frame are movably connected through buckles. The scalpel placement rack is provided with the oblique placement layer, scalpels are placed at a placement end and slide automatically to an arrangement end, the partitions are sprung up to separate the scalpels, the problems of wear and damage between the scalpels are solved, and the scalpel placement rack has the advantage of effectively separating the scalpels, and reduces manual labor.
