4results about How to "Avoid reinfection" patented technology

Described herein are compositions and methods for reducing the risk of infecting a subject with a respiratory disease or reducing the risk of spreading a respiratory disease from a first subject to a second subject. In some cases, the compositions or methods described herein may comprise modulators (e.g., pattern recognition receptors, such as STING agonists, such as cGAMP), in some cases, the compositions or methods described herein may comprise liposomes that may be used to encapsulate one or more STING agonists. In some cases, the liposomes of the compositions or methods described herein may comprise one or more antigens attached to, integrated into, or associated with a liposomal membrane of the liposomes.

The utility model relates to the technical field of sterilization devices, and discloses a high-temperature sterilization device for pet ration processing, which comprises a sterilization box, a driving groove is arranged in the middle of the inner wall of the upper end of the sterilization box, an adjusting screw rod is rotatably connected between the inner walls of the front end and the rear end of the driving groove, and a sliding seat is sleeved on the outer wall of the adjusting screw rod in a threaded manner. The lower end face of the sliding seat is fixedly connected with a mounting seat, and a plurality of ultraviolet germicidal lamps are fixedly arranged on the lower end face of the mounting seat. According to the utility model, through the arrangement of the movable sterilization structure, multi-surface sterilization can be carried out on the grain ration, so that the problem that other grain ration is infected due to poor sterilization quality at dead corners is avoided, the practicability is better, and meanwhile, through the arrangement of the arrangement of a placing tray retractable structure, the purpose of automatically retracting and storing can be achieved; therefore, the problem of re-infection caused by long-time contact between unutilized grain ration and the outside is effectively avoided, and better protectiveness and low cost are achieved.

A device for root canal treatment, comprising a tube with a first taper configuration and a plurality of through holes on the tube wall. A brush is assembled in the tube, comprising bristles and a brush rod, and the bristles are attached to the brush rod at one end. A control member is used to control the shape of the brush, and the bristles attached to the brush rod are unfolded outside the tube wall, so that the brush has a second taper and is in contact with the inner wall of the root canal cavity established by the root canal file. The water generated by ultrasonic oscillation flows in the tube, and flows out from the through holes along the bristles and into the root canal prepared by the root canal file for filling. It has been verified that the device is easy to put into the root canal prepared by the root canal file, the tube wall tissue debris is used for flushing, the residual in the root canal is effectively avoided, the filling of the root canal is facilitated, the postoperative repeated infection is prevented, the recovery of the tooth function is accelerated, and the healthy oral environment is maintained.

The invention discloses externally-applied parasite-expelling traditional Chinese medicine extract dry powder for animals, which belongs to the technical field of parasite expelling and comprises a traditional Chinese medicine extract and a dispersion carrier. The traditional Chinese medicine extract is prepared by mixing one or more of croton seed extract, rhizoma smilacis glabrae extract, cortex meliae extract, flos genkwa extract, radix sophorae flavescentis extract, fructus cnidii extract, chaulmoogratree seed extract, cortex dictamni extract, radix stemonae extract, radix euphorbiae lantu extract, gelsmium elegans extract, desmodium triquetrum extract, pepper extract, pepper extract, spina gleditsiae extract and veratrum nigrum extract in any proportion. The composition is used for preventing and killing ectoparasites such as scabies, lice, fleas and ticks of pets such as pigs, cattle, sheep, poultry, dogs and cats, can also be used for feeding places to prevent repeated infection of parasites, and in addition, the parasite expelling components are pure traditional Chinese medicine extracts, so that the problem of drug residues and the problem of drug resistance of chemical drugs are avoided, and the composition is safe and reliable. The medicine is directly spread on animal body surfaces and in a feeding environment, so that the medicine is labor-saving, safe, environment-friendly and beneficial to human health.
