An intra-oral cavity device for preventing contact between upper and lower teeth of an anesthetized patient. The device includes an elongate pillow that when gripped between the teeth of a patient, prevents contact between the teeth and/or gums and thereby prevents damage to the teeth and/or gums. The pillow may be made of a fibrous, porous and/or absorbent material. The device is adapted for single use and thus disposal after use by a patient. A method of the use of performing surgery using such a device is also provided.

The multi-section deployable and articulating endoscope is designed with tubing and flat cables that are small enough that the endoscope becomes a thin stick that is minimally invasive and usable with other devices in a common port. The endoscope includes very thin flat cables that are used for electrical connectivity and threaded above and below an articulation and deployment hinge for opening the endoscope passively using an adjustable tension spring, or by pulling on a first cable and closing the endoscope by pulling on a second cable, When in a tubular configuration the endoscope may be inserted into the port and an insufflation membrane inside the port forms an air seal with the endoscope, which aids in insufflation and desufflation.

The endoscope includes one or more tubes for creating an air jet stream above the camera to act as a shield for keeping the camera clean.

A microencapsulated botanical insect-resist agent comprises 50-70 parts of microcapsule core materials, 5-10 parts of microcapsule adhesives and 20-30 parts of microcapsule wall materials by weight, wherein the core material is one or more of fennel essential oil, folium artemisiae argyi essential oil, cinnamon essential oil and clove essential oil; the adhesive is one or more of gelatine, peach gum, glycerol and ethyl acrylate; and the wall material is one or more of porous starch, cyclodextrin and diatomite. When used for grain storage, the insect-resist agent can achieve the sustained release and efficient insect-resist effects on sitophilus zeamais and tribolium confusum. The insect-resist agent achieves sustained release through one-time use and can lengthen the storage time, reduce the insect-resist working capacity and lower the grain storage cost.

A zip tie is disclosed that has a substantial longitudinal rigidity enabling pushing through fabrics. Associated with this tie is a catch with integral, tapered and rigid barbs. The tie strip has teeth that are tapered and essentially rigid, unlike other tie strips with mere bumps or rounded strips acting as teeth to engage flexing engaging catches. This zip anchor is intended for one time use. Though the catch may be forced off the tie for removal the catch barbs are deformed and unable to be used to anchor thereafter. This zip tie combination is most useful in attaching, anchoring members to fabric of web gear or clothing.

The invention relates to a surgical smoke filter, and belongs to the field of medical equipment. The surgical smoke filter comprises a closed shell with an inlet and an outlet, wherein the inlet and the outlet are formed in two parallel opposite faces of the closed shell, the closed shell comprises a harmful gas filtering cavity and a carbon dioxide absorbing cavity in sequence from the inlet to the outlet, the outlet of the closed shell is covered with a first multi-hole plate, and the inlet and the outlet of the closed shell extend outward from the shell to form an air inlet tube and an air outlet tube respectively. The surgical smoke filter is compact in structure, convenient to use, easy to operate, economical, efficient and capable of effectively clearing away harmful particles and carbon dioxide in smoke generated in laparoscopic surgery at the same time, the harmful particles and the carbon dioxide in smoke are easy to recycle and destroy, and the surgical smoke filter meets the administrative regulation for disposable sterile medical apparatuses.

The invention relates to a passive audible and visual alarm temperature indicating device used for monitoring the temperature of electrical connectors among power supply unit parts in a power system.The temperature indicating device is composed of an induction power supply, a voltage stabilizing part, a temperature detection part, an audible alarm system and a luminescent display part, and has the advantages of high temperature measurement accuracy, good safety, obvious effect with common action of audible prompt and visual prompt no matter in the day or night, an audible and visual alarm given in the case of overheat occurred on a connecting point of electrical equipment, and no need of independently adding an external power supply, thus guaranteeing long-term use of the device without need of maintenance; and the device further has the advantages of repeated use, long service life and extremely low energy consumption relative to a disposable temperature indicating wax piece. Only anew temperature measuring element is required for replacement even though the accidental temperature of a contact point is suddenly risen to burn down the temperature measuring element; and temperature detection can be realized only by pasting the temperature measuring element to a heating part to be detected, thus the device is convenient in use.

The invention relates to the field of chemistry, in particular to a preparation method of a narrow-distribution polyether. The preparation method comprises the following steps: A, adding small-molecule alcohol and a composite catalyst to a reaction vessel, raising the temperature to 80 to 130 DEG C, and vacuumizing and carrying out dehydration, wherein the composite catalyst is formed by compounding phosphazene and double-metal cyanides; B, controlling the reaction temperature and pressure, adding epoxide into the reaction vessel, and enabling reaction till the pressure is no longer lowered to obtain the narrow-distribution polyether. According to the invention, the composite catalyst of the phosphazene and the double-metal cyanides is used for preparing the narrow-distribution polyether, so that the problems of large use amount and high cost for the single use of the phosphazene and incapability of directly catalyzing the small-molecule alcohol to prepare the polyether by the single use of the double-metal cyanides are solved. The preparation method disclosed by the invention is simple, the cost is low and the preparation method of the narrow-distribution polyether is of great significance on promoting the application and development of the polyether.

The invention relates to an extraction method, and belongs to the technical field of hydrometallurgy. Salt generated by a saponifying agent in a solvent extraction and separation process is prepared into a regenerated saponifying agent and/or regenerated acid to be reused. The extraction method has the advantages that the regenerated saponifying agent is good in activity, no impurities are introduced into an extraction system any more, impurities carried by a disposable saponifying agent into the extraction system are avoided, the impurities of iron, silicon, heavy metal and the like in a product are reduced, the quality of the product is improved, resources are saved, and the cost is reduced. The defect that a large amount of salt-containing sewage is discharged while large amounts of acid and alkali are consumed during solvent extraction is overcome. The extraction method is simple, easy to control, convenient to use, safe and reliable and facilitates industrial production.

An odor masking tablet composition includes a solid single-use tablet comprising at least one base oil, a reactive agent, a base material, and an emulsifier. The tablet is packaged for individual use and transportation, or multiple tablets are packaged together. The tablets function to rapidly dissolve when deposited into toilet water and produce an active surface barrier for trapping unpleasant odors within the water. The tablets also include a scented material, and a coloring agent for changing the color of the water to which the tablet is placed.

The invention provides a disposable toilet warm-keeping seat cushion comprising a flannelette cover and a foam core placed in the flannelette cover. The bottom of the flannelette cover is provided with an adhesive layer. The toilet warm-keeping seat cushion integrally matches an outer ring of a toilet in shape.
