The present application relates to the field of pharmaceutical preparations, in particular to a long-acting eye composite preparation for improving the symptoms of blepharitis. The preparation comprises a combination of two active ingredients in a therapeutically effective amount, and one or more ion-sensitive polymers or their complex systems, which are used to treat the symptoms of blepharitis caused by Demodex through a special double-cavity drug delivery bottle. By using a specific ion gel matrix concentration and regulating the viscosity of the drug solution before it reaches the eye, the limitations of traditional eye preparations are overcome, the retention time of the drug in the eye is prolonged, the bioavailability is improved, the probability of adverse events is reduced, and the medication compliance is increased.

This application discloses an automatic assembly device and method for O-rings in the injector holes of an engine cylinder head, relating to the field of engine cylinder head technology. It includes a cylinder head positioning mechanism for transporting and positioning the cylinder head; a feeding mechanism including a feeding base and a vibrating screen mechanism, a stop mechanism, and a lifting mechanism connected to the feeding base; the vibrating screen mechanism sequentially feeds multiple O-rings to the mounting position of the stop mechanism; the mounting position of the stop mechanism has a support claw connecting the O-rings inside, and a baffle assembly for opening and closing is located at the top of the mounting position; the lifting mechanism has a top plate and a lifting device, which can lift the top plate to eject the O-rings on the support claws; the assembly mechanism includes a conveying mechanism, an assembly base, a drive device, and a gripping mechanism; the assembly base is movably connected to the conveying mechanism; the drive device is connected to the assembly base; the drive device drives the gripping mechanism to move to grip the O-rings on the support claws and press the O-rings into the injector holes of the cylinder head.

The application relates to the technical field of detection, in particular to a lead halide perovskite quantum dot material and a preparation method and application thereof. The method comprises the following steps: mixing a lead source, 1-octadecene, oleylamine, oleic acid and a cesium source, and then carrying out ultrasonic treatment to obtain a mixed solution; placing the mixed solution in a tip ultrasonic instrument, first activating at low power, then improving the power to carry out ultrasonic synthesis reaction, washing the obtained product with a first organic solvent, dispersing the product in a second organic solvent, adding a surfactant, again carrying out ultrasonic treatment and tip ultrasonic activation, and finally preparing the lead halide perovskite quantum dot material. The lead halide perovskite quantum dot CsPbX3 (X is Cl, Br or I) material obtained by the method has excellent quantum dot luminescence performance, good stability in a reverse microemulsion system, can introduce a to-be-detected substance, and realizes quantitative analysis through fluorescence or chroma testing.
