47 results about "Artificial salivas" patented technology

Artificial salivary gland devices and assemblies are provided. The present disclosure provides artificial salivary pump / gland devices and assemblies, and related methods of use. One embodiment utilizes the interstitial / marrow fluid reservoir within the underlying mandibular or maxillary bone as a source for replacement saliva. The salivary pump / assembly, which is implantable in the mandibular or maxillary bone as a dental implant and driven by incidental tooth contact and masticatory forces, harvests interstitial / marrow fluid and treats it via semi-permeable membrane technology and soluble particles as a continuously available saliva replacement. Masticatory forces and tooth contact power the pump to both harvest interstitial / marrow fluid and drive flow through a bed of ion-exchange resins and / or soluble particles to adjust fluid chemistry providing a continuously available saliva-like solution. Exemplary devices and assemblies can also be utilized to introduce beneficial bacteria into the oral cavity and / or be utilized as a delivery system for drugs / therapeutic agents.

The invention relates to artificial saliva, which comprises a plurality of inorganic salt, HPMC, a preservative, a flavoring agent and other components. The artificial saliva has the following advantages that: (1) the artificial saliva can rapidly improve symptoms of a patient suffering from xerostomia, and can maintain the function in a longer period; (2) the artificial saliva has good stability; and (3) the artificial saliva has a good mouthfeel when in use.

The invention relates to a method for detecting a release situation of nicotine in buccal tobacco products, which is characterized by comprising the steps of simulating the release situation of the nicotine in the buccal tobacco products in the human mouth, instantly quantifying the release quantity and the release speed and then detecting the release speed and the release degree of the nicotine in the buccal tobacco products. The release and the collection of the nicotine are realized through a release and collection device in vitro; by means of the device, the release process of the nicotine in the buccal tobacco products in the human mouth can be simulated and nicotine release solutions can be the instantly collected, wherein the release process is a process that the nicotine is continuously extracted from the buccal tobacco products by utilizing artificial saliva at a constant temperature; and the detection of the nicotine content in the release solution is realized through a highperformance liquid chromatography. The method has the advantages: the release speed and the release degree of the nicotine in various buccal tobacco products can be rapidly and accurately detected with good repeatability, high sensitivity and short detection period and is suitable for the rapid analysis of mass samples for different industries and different purposes.

The invention relates to a method for quickly detecting whether cigarette tipping paper sticks to lips, and belongs to the technical field of analysis and detection. According to the national standard, the cigarette tipping paper to be tested is used to roll cigarettes, the artificial mouth skin is flatly fixed on a test board of a certain height, artificial saliva is prepared, and the artificial saliva is applied to the tipping paper of the cigarette to be tested. , and then immediately paste the sample to be tested coated with artificial saliva on the artificial mouth skin in a suspended manner; counting from the time when the sample to be tested is pasted on the artificial mouth skin, record the moment when the sample to be tested falls from the artificial mouth skin; If the average time between sticking and falling of the sample to be tested is ≥3s, the tipping paper of the cigarette to be tested has lip sticking force. The method of the present invention is fast, simple, and has good repeatability, which can avoid the influence of subjective factors and differential characterization brought about by the traditional artificial sensory evaluation, and greatly saves the detection cost. There are advantages in the product.

The invention discloses an oral care composition for treating xerostomia and the application of the oral care composition. The oral care composition consists of the following components in parts by weight: 0.1-1.5 parts of an olive extract, 0.1-1 part of lactoferrin microspheres and 0.1-5 parts of zinc oxide microspheres. The oral care composition can stimulate saliva secretion, relieve xerostomia, treat gingivitis and alleviate halitosis, can also achieve the effect of artificial saliva, realizes the effect of sterilizing the mouth, facilitates oral health of patients with xerostomia, and can be used for preparing oral care products for treating xerostomia and complication thereof.
