A non-invasive method of characterizing burn injuries using near infrared spectroscopy is described. In the method, a beam of light is emitted into the burnt tissue portion at two or more different tissue depths. The spectra are then compared using multivariate analysis to determine diagnostic regions of the spectra. This information is used to categorize the burn. In some cases, the diagnostic regions correspond to wavelengths related to the hemodynamics of the tissue portion. The spectra can also be repeated over time, thereby allowing trends and changes in the spectra to be measured. This data is in turn used to categorize the burn as either a superficial burn, partial thickness burn, deep partial burn or a full thickness burn. Once the burn has been categorized, the clinician can intervene as needed to treat the burn.

The present specification discloses an endoscope having a tip section equipped with multiple viewing elements. Each of the viewing elements' field of view is illuminated by a discrete illuminator, such as a LED, being operated in a flash mode. The flash mode of operation of the LEDs enable doctors to obtain a position of the endoscope tip within a patient's body from outside by viewing the light emitted by the LEDs. Since the light is emitted for short pre-defined periods of time, the heat generated by the LEDs during their periods of operation is within a safe threshold value, and does not cause any burn injury inside the patient's body.

The present invention relates to a Hookah otherwise known as a water pipe or Nargile. The hookah is used to smoke tobacco or other herbs that are heated using a hot charcoal. With multiple tobacco bowls, this hookah allows the user to consume a mixture of smoke from different flavored tobaccos. The various bowls are independent from each other and spaced apart so that the heat from one does not affect the others. The spacing of the bowls also protects the user from burn injuries while replacing the tobacco or charcoal in each bowl. The smoke from each bowl is directed into a stem tube where it is mixed before being filtered and cooled by water in preparation for consumption. Each tobacco bowl can be connected to a flow control device that allows the user to fine tune the amount of smoke from each bowl and achieve the preferred flavor.

A lid for a beverage container is described. The lid has a basin that is designed to enhance the user's olfactory experience when drinking a beverage from the container and lid. As the user tilts the container and lid to take a drink, the beverage pours through an opening on the basin valley and flows across a sipping surface area to the user's mouth, thus allowing the beverage to aerate, evaporate, and cool. The basin is sized and dimensioned to channel and concentrate the vapor rising from the beverage towards the user's nose as the user sips the beverage. The basin and the opening are sized and dimensioned to provide a comfortable and secure feeling when drinking hot beverages. In this manner, the lid enhances the drinker's olfactory experience and provides better controllability of the flow of a hot beverage to prevent burn injuries.

The invention discloses a preparation method of a self-adhesive hydrogel having anti-freezing/heat-resistant performance. The method adopts a hydrogel solvent system consisting of glycerin and a watermixed system, and powerful hydrogen-bond interaction between glycerin and water enables water to be stably immobilized in a polymer network, can destroy the formation of ice crystal lattices at a lowtemperature and prevent moisture volatilization at a high temperature, and endows the hydrogel with long-term stability, anti-freezing performance and heat resistance. Besides, synergy between polydopamine, glycerin and polymer network enhances the mechanical property of hydrogel, so that the hydrogel has high strength, high toughness and good restorability. Furthermore, the addition of the polydopamine component makes hydrogel have good adhesion, and hydrogel can be adhered to surfaces of substrates with different chemical properties. The self-adhesive hydrogel with the anti-freezing/heat-resistant performance prepared with the method can be used as a wearable dressing to protect skin from cold injury or burn injury in an extremely cold or hot environment.

The invention discloses a resin CBN (cubic boron nitride) grinding wheel for machining a saw blade base body. The resin CBN grinding wheel comprises a base body and an abrasive material layer. The abrasive material layer comprises the following raw materials in percent by volume: 15%-30% of CBN abrasive materials, 30%-45% of phenolic resin powder, 3%-6% of villiaumite grinding-aiding materials, 5%-15% of heat conduction materials, 5%-25% of metallic oxide, 2%-5% of solid lubricating materials and 4%-8% of pore forming materials. Compared with a common white corundum grinding wheel, the resin CBN grinding wheel is high in grinding amount, high in machining efficiency, long in finishing interval and low in speed of loss; and the grinding wheel changing frequency is reduced. Because the grinding wheel has high self-sharpening performance, burn injury and slow grinding of the CBN grinding wheel can be eliminated in a grinding process. On a grinding machine with low revolving speed of 1450 revolutions per minute, the CBN grinding wheel is used for replacing the common white corundum grinding wheel, and the saw blade base body can be quickly ground into a saw blade base body with the given size.

A system for prevention of fires in operating rooms as frequently arises from electrocautery and laser systems comprising an electrocautery instrument having a shielding gas that is expelled from the distal-most end thereof to thus prevent the cautery tip spark from coming into contact with an oxygen-enriched environment that may otherwise propagate the spark into a full-fledged fire. The systems can further be coupled with oxygen sensors, alarms and mechanisms for limiting the delivery of oxygen. Additional refinements include incorporating heat sensory strips to the distal ends of oxygen delivery systems, which are in turn coupled with a thermocouple device set to turn off oxygen delivery or electrosurgical system at given levels of heat to thereby limit the extent of burn injury. Further refinements also include the use of nonflammable inserts to the tips of the oxygen delivery systems such that in the event of a fire the plastic does not catch on fire and in effect turn into a blowtorch.

The present invention describes the incorporation of liposomal gene constructs directly into a wound to further improve wound repair, or into wound coverage and/or closure materials to enhance the functionality of the material. The present invention further describes the use of human fetal membranes (e.g., amnion) enhanced with the liposomal gene therapy as a wound coverage material in full-thickness wound repair. The enhanced fetal membranes or enhanced cadaver skin have advantages over currently used materials lacking the liposomal gene construct and are an efficient and safe approach to improve clinical outcome in patients with burn injuries.

An ultrasonic wave hair set apparatus is configured by a main frame, an ultrasonic vibration block provided on the main frame, a pinching lever rotatably provided on the main frame, a presser plate provided on the pinching lever and having a pressing face. The ultrasonic vibration block is further comprised of an ultrasonic oscillator and an ultrasonic horn having a vibration face, and a comb shaped protection member is provided to enclose the vibration face. Even if a user penetrates a finger between the pinching lever and the main frame, the finger touches the protection member, so that it rarely touches the vibration face directly. Consequently, the ultrasonic vibrations are not transmitted to the finger, and burn injury can be prevented.
