12 results about "Oral fluid" patented technology

Oral fluid is the liquid present in the oral cavity. Oral fluid is a mixture of saliva and "oral mucosal transudate". Saliva is produced by the salivary glands. Oral mucosal transudate enters the mouth by crossing the buccal mucosa from the capillaries. Oral fluids contain both pathogens and antibodies. In humans,...

Porcine epidemic diarrhea virus attenuated strain and vaccine and application thereof

PendingCN121227643ADigestive systemMicroorganism based processesPassive ImmunizationsImmunogenicity
The invention relates to the field of veterinary biological products, in particular to a porcine epidemic diarrhea virus attenuated strain and a vaccine and application thereof. The porcine epidemic diarrhea virus attenuated strain provided by the invention is obtained through in-vitro separation culture and continuous five rounds of plaque purification and screening technology, and has stable culture characteristics. Meanwhile, the virulence of the strain on newborn piglets and weaned piglets is remarkably reduced, and the virulence does not have the phenomenon of reversion after continuous passage for five times in a pig body. The strain has good immunogenicity, and mucosal immunity and systemic immune response of an organism can be activated at the same time by adopting an oral immunization mode. A neutralizing antibody of 1: 8-1: 16 can be detected in oral fluid and serum after the piglets are immunized for 14 days, and a large amount of sIgA is generated in milk after the pregnant sows are immunized, so that the piglets obtain effective passive immune protection.

Oral tooth pulp disease treatment auxiliary device

The invention relates to the technical field of medical instruments, in particular to an oral cavity tooth pulp disease treatment auxiliary device which comprises a handle, a sleeve is fixedly connected to the handle, and a lighting mechanism used for providing lighting and a saliva suction mechanism used for sucking saliva in the oral cavity are arranged at the end, away from the handle, of the sleeve. The saliva suction mechanism is communicated with a suction mechanism for assisting in sucking liquid; a linkage mechanism is also arranged in the handle and is used for driving the illumination mechanism to change the illumination angle and driving the saliva suction mechanism to change the aperture of the saliva suction port; the linkage mechanism is further used for driving the suction mechanism to operate synchronously so as to assist in saliva suction. When a doctor rotates the handle linkage mechanism, the light angle can automatically adapt to the current treatment area, the saliva suction opening is synchronously adjusted to the corresponding size, the suction mechanism is started accordingly to assist in cleaning oral liquid, the doctor can always concentrate on instrument operation, through cooperative linkage of the illumination function and the saliva suction function, the treatment view blind area can be reduced, and the treatment effect is improved. And the operation precision is improved.
