  • Patent number: 11541324
    Abstract: A smoke generator includes an oil tank receiving an oil to be pumped by an oil pump to a vaporization tube where the oil vaporized into smoke after heating by a heater. A pre-pressurization oil supply device is disposed between the vaporization tube and the oil pump. When the pre-pressurization oil supply device is in a non-supply state not intercommunicating with the vaporization tube, the pre-pressurization oil supply device maintains its internal pressure, and the oil in the pre-pressurization oil supply device is not delivered to the vaporization tube. When the pre-pressurization oil supply device is in an oil supply state, the pre-pressurization oil supply device intercommunicates with the vaporization tube, and the oil in the pre-pressurization oil supply device is rapidly delivered to the vaporization tube.

  • Patent number: 11191718
    Abstract: The present invention provides an ophthalmic gel and a preparation method thereof. The ophthalmic gel comprises: an antibiotic; a nanocarrier, wherein the nanocarrier is used to load the antibiotic; and a biodegradable matrix, wherein the biodegradable matrix is compatible with the nanocarrier to carry the nanocarrier. When the ophthalmic gel of the present invention is applied to the surface of the cornea and conjunctiva of the eyes, the biodegradable matrix is automatically degraded and the nanocarrier carried by the biodegradable matrix will slowly release the antibiotic, loaded in the nanocarrier, at an appropriate rate to overcome the high-frequency use of general ophthalmic drugs and easily caused blurred vision; the present invention further comprises an ophthalmic gel preparation method.
