Abstract: A device combining positioning and injection systems for injection within a body cavity, comprises: a tubular housing surrounding an accommodating space and having an opening hole fluidly connected to the accommodating space; a curved channel fluidly connected to the accommodating space and the opening hole; an injection needle disposed inside the accommodating space and the curved channel; the injection needle having a piercing portion penetrating through the opening hole and configured to extend outward from or retract inward into the opening hole; a plurality of ultrasonic transducers installed at the tubular housing and at two opposite sides of the opening hole; wherein at least one of the ultrasonic transducers being used to transmit a detection signal, and at least one of the ultrasonic transducers being used to receive the detection signal; a monitoring unit connected to the ultrasonic transducers via a transmission unit for information transmission therebetween.

Abstract: Disclosed are a method and an appliance for extending the production of nitric oxide by microencapsulated spinach extract powder and acidic gel. The appliance includes a microencapsulated spinach extract acting as a nitric oxide donor, and an acidic gel having a sufficient acidity to transform the spinach extract into nitric oxide. The method and appliance for extending the production of nitric oxide by spinach extract microencapsulated powder and acidic gel can release NO for a long time and provide a long-term effect to the affected position.

Abstract: Methods and compositions are provided for generating and applying long-lasting therapeutic nitric oxide (NO) gas from the reaction of a least one microencapsulated nitrite salt and an activating volume of an aqueous acidified gel that has sufficient acidity to convert the nitrite salt to a nitric oxide (NO) and further provides a reducing property that retains the NO in bioactive form

Abstract: Methods and compositions are provided for generating and applying long-lasting therapeutic nitric oxide (NO) gas from the reaction of water-soluble chemical reactants microencapsulated in polymer matrices. In some applications the microencapsulated reactants are introduced in an aqueous gel, and in other applications they are introduced to the area of therapy either directly or in a medical device such as a therapeutic pad or dressing. In some applications, the microencapsulated chemical precursors are maintained in close physical proximity to one another in a limited volume, and using a limited amount of solvent residing within that same volume to extract and process the chemical precursors to form NO.
