Abstract: To provide a gas-liquid separator of a water electrolysis system, comprising: a liquid feeding atomizer and a gas-liquid separation chamber, wherein the liquid feeding atomizer includes a liquid feeding pressurized tube; and an atomizing spray head, in which the atomizing spray head converts a gas-liquid mixed liquor after pressurized by the liquid feeding pressurized tube into a mist droplet gas-liquid mixture. The gas-liquid separation chamber comprises a spiral flowing way, and the spiral flowing way extends the time that the mist droplet gas-liquid mixture spraying into the gas-liquid separation chamber flows downwards to the bottom of the gas-liquid separation chamber; an ultrasonic oscillation mechanism; a stirrer; an internal reservoir; and a filter mechanism, which performs the gas-liquid separation for unbroken bubbles in the mist droplet gas-liquid mixture through the pore difference.

Abstract: Valve clip having locking mechanism includes first clamping arm, second clamping arm, linking member, push-pull device and locking device. The locking device fitted with the linking member and includes locking head and self-locking rod. The linking member hinged to each of the first clamping arm and the second clamping arm which include a long arm whose end is hinged to the push-pull device and a short arm whose end is provided with a locking portion. When the push-pull device operated to enlarge opening angle between the long arms of the first clamping arm and the second clamping arm in an open state, the locking portions of the first clamping arm and the second clamping arm are in a staggered fit state; and when to narrow the opening angle in a closed state, the locking device moved to cause the locking head to be fitted and locked to the locking portions.

Abstract: The present application relates to a transcatheter prosthetic valve replacement system including a delivery catheter, a frame, a prosthetic valve, and one or more clamping devices. The prosthetic valve is fixed in the frame. The clamping device is connected to a periphery of the frame. The frame and the clamping device can be preloaded in the delivery catheter. The clamping device includes a clamping member, a collar, and a control member. One end of the clamping member is a fixation end which is fixedly connected to the frame, and the other end of the clamping member is a deployable resilient segment which can be compressed and released.

From being compressed to being fully released, the clamping member in sequence has two configurations.

Abstract: The present application relates to a stepwise-clamping type valve prosthesis including a frame body and a clamping member. The frame body has a channel allowing blood to flow therethrough. The clamping member includes a first clamping member and a second clamping member. One end of the first clamping member is connected to the frame body, and the other end of the first clamping member is a free end. The second clamping member is connected to the first clamping member. The clamping member has three states in sequence from being restricted to being fully released. In the first state, the first clamping member and the second clamping member are both restricted and restricted. In the second state, the second clamping member is restricted, and the first clamping member extends in a radial direction of the frame body and is capable of reaching a position between a valve leaflet and a heart wall.

Abstract: A focusing and leveling apparatus, including: an illumination light source (201) for emanating a light beam; an illumination lens group (202), a projecting unit, an object (209) being measured, a detecting unit, a refractive unit, a relay lens group and a photoelectric detector (220), disposed sequentially in this order in a transmission path of the light beam. The projecting unit includes projection slits (203) defining a plurality of non-linearly arranged marks, such that after passing sequentially through the illumination lens group (202), the projecting unit, the object (209) being measured and the detecting unit, the light beam emanated by the illumination light source (201) becomes a plurality of non-linearly arranged sub-beams corresponding to the plurality of marks. The refractive unit is so configured that after passing through the refractive unit, the plurality of sub-beams form a plurality of linearly arranged light spots.

Abstract: Surfactin is produced from Bacillus subtilis ssp. containing sfp gene (lipopeptide biosurfactants produced by fermentation). Production of surfactin at present is mainly by liquid fermentation, but the production costs are high due to difficulty in purification resulted from addition of the defoaming agent during the production process. Therefore, present invention conducts physical or chemical mutation on Bacillus subtilis subsp. isolated from Thailand seawater shrimp ponds and screens for the mutant strain of Bacillus subtilis subsp. based on sfp gene expression and then produces surfactin from the mutant strain by semi-solid state fermentation.

Abstract: A method for preparation of a feed additive containing surfactin, which uses a high-yield mutant strain, Bacillus subtilis T, and soybeans as the substrate in semi-solid state fermentation and after drying and grinding of the fermented soybeans into soybean powder to give a feed additive containing surfactin. Each kilogram of the fermented soybean powder contains about 6-7 g of surfactin. Feeding grouper with the feed additive containing surfactin can promote growth rate, increase expression of immune genes (e.g. AMP, Mx and IFN-induced protein), and lower mortality rate of virus-infected fish, indicating the feed containing surfactin has the effects of growth promotion, immunity enhancement and provides resistance to pathogen infection.
