The sputum suction nursing plate comprises a lower box body and an upper box body, the upper box body is connected with the lower box body through a hinge, and the sputum suction nursing plate further comprises an inflatable pillow fixed in the lower box body; the groove is formed in the inflatable pillow; the collecting boxes are symmetrically arranged in the lower box body, and the two collecting boxes are symmetrically arranged on the two sides of the inflatable pillow; according to the utility model, sputum is effectively prevented from falling onto a medical bed, and a patient is effectively prevented from vomiting caused by seeing the sputum for a long time.

The invention relates to the technical field of film-coated proppants, in particular to a film coating method and device of a film-coated proppant, and the film coating method of the film-coated proppant comprises the following steps: S1, material pretreatment: washing aggregate, soaking the aggregate in an aqueous solution of a silane coupling agent, filtering and then drying to obtain clean aggregate; s2, primary film covering is conducted, specifically, the clean aggregate is heated and then transferred into a powerful sand mixer, phenolic resin, oleophylic modified fumed silica, a phenolic resin curing agent and a lubricating agent are sequentially added in the stirring state, and first covered aggregate is obtained; s3, secondary coating: sequentially adding polyether polyol, a cross-linking agent, a polyether polyol curing agent and a metal catalyst into the first coated aggregate, finally adding oleophylic modified fumed silica, and fully stirring and mixing to obtain second coated aggregate; and S4, packaging to obtain the film-coated proppant. Wherein the phenolic resin and the oleophylic modified fumed silica are mixed and dispersed in advance.

The invention discloses an oral cavity auxiliary supporting device and method for gastroscopy and belongs to the technical field of oral cavity supporting.The oral cavity auxiliary supporting device comprises an oral cavity auxiliary supporting mechanism, and a saliva drainage mechanism is assembled on the oral cavity auxiliary supporting mechanism; the oral cavity of a patient is opened through the guide cavity, then the gastroscope penetrates through the guide cavity, the gastroscope guide wheel can guide and limit the gastroscope, the gastroscope is prevented from shaking, the gastroscope can be stably inserted into the stomach of the patient, and the gastroscope guide wheel can be driven to rotate in the gastroscope insertion process; the gastroscope guide wheel can drive the transmission screw to rotate through transmission of the transmission wheel and the transmission belt, the transmission screw drives the first piston to move through the transmission nut, the first piston pushes liquid into the other side of the fixed bottom shell through the conveying pipe, the liquid flow of the conveying pipe is adjusted through the first valve, and therefore the rotating speed of the gastroscope guide wheel can be adjusted. The speed of the gastroscope is further limited, so that constant-speed insertion of the gastroscope can be assisted, and the problems of discomfort and pain to a patient caused by unstable manual operation are avoided.

This utility model discloses a teething toy, relating to the field of maternal and infant product technology. The teething toy includes a baffle, a mouthpiece, a protective cover, a stopper, and a handle. The baffle is petal-shaped, which can catch food juices and saliva flowing from the mouthpiece, preventing liquid from flowing onto the hands to ensure hand hygiene and reduce the cleaning burden on parents. It also forms a natural limit against the outside of the mouth to prevent the mouthpiece from inserting too deeply. The mouthpiece is integrally formed at the narrow end of the baffle and communicates with its interior. The protective cover is detachably connected between the baffle and the mouthpiece and can cover the mouthpiece. The stopper is integrally formed with the handle and can pass through the inside of the baffle and be detachably connected to the mouthpiece.
