7results about How to "Increase contractility" patented technology

The utility model relates to bag technology field discloses a kind of outdoor sports backpack quick tightening mechanism, including backpack main body, elasticity mechanism, cloth belt, shoulder strap and fixed band, the utility model in to the elasticity of backpack main body side face is contracted, so that elasticity drives the fixed band of backpack main body side face to be mutually close, so that backpack main body side face is contracted by the contraction of elasticity and is tightened space, prevent the interior article of backpack main body from being less and producing shaking when moving, make elasticity continuous "S" shape contraction and tighten the stability of article in the backpack main body, prevent the part article in the backpack main body from being not easily fastened by elasticity and shaking when moving, and the force of upper and lower sides of blocking plate and arc strip clamping elasticity is under the action of improving fixed force to resist the contraction force of elasticity, so as to improve the fastening effect of elasticity contraction, prevent the jolt in the process of moving to cause elasticity slowly loosen and tighten backpack main body.

This invention discloses a low-temperature thermoplastic composition and the low-temperature thermoplastic material made therefrom, as well as its applications, relating to the field of medical materials technology. The low-temperature thermoplastic composition mainly comprises the following components: thermoplastic resin, reinforcing filler, and radiation crosslinking agent; the thermoplastic resin includes polyurethane, and each 100 parts of the low-temperature thermoplastic composition contains at least 27 parts of a first polyurethane with a flow start temperature of 50-95°C and an open time of at least 6 minutes. Through the selection of polyurethane and the combination of reinforcing filler, the low-temperature thermoplastic composition enables the low-temperature thermoplastic material to have lower shrinkage and a longer operating time, allowing the low-temperature thermoplastic material prepared from the composition to be used for fixation of parts with higher operating time requirements.

The flying wing type rechargeable underwater cruise underwater glider comprises a flying wing type shell, a main pressure-resistant cabin is installed on the top of the flying wing type shell, and a temperature difference energy power generation system, an underwater cruise system, an ocean current energy power generation system and a buoyancy adjusting system are sequentially and symmetrically installed on the two sides of the main pressure-resistant cabin; the ocean current energy power generation system comprises a power generation system, a supporting system and a retractable mechanism, the top of the supporting system is provided with the power generation system, and the bottom is connected with the retractable mechanism; the power generation system comprises an impeller system, and an impeller of the impeller system can stretch out, draw back and be folded. The system can be freely switched among three working modes of underwater gliding, underwater residing and underwater cruising, and tasks can be executed for a long time. According to the flying wing type underwater glider, the running system and the ocean current energy power generation system can be adjusted by the retracting and releasing system to rotate, the appearance of the flying wing type underwater glider is not changed while the underwater residence, cruising and power generation functions of the glider are achieved, and the excellent fluid performance in the gliding working mode is guaranteed.

The application discloses a kind of pelvic floor muscle training devices, including at least two air bags, air pipe and charge and discharge component, wherein, air bag includes probe part and bending part, probe part and bending part are communicated, probe part and bending part inside are hollow structure, air pipe is connected with the end of probe part away from bending part, charge and discharge component is connected with the end of air pipe away from probe part, charge and discharge component is configured to charge and discharge air bag by air pipe, to make probe part and bending part swell and shrink.The above scheme provided by the application, charge and discharge air bag by charge and discharge component, at this time, probe part and bending part can swell and shrink, so in the process of swelling and shrinking, pelvic floor muscle can be pressed and relaxed uninterruptedly, so as to improve the contraction force and coordination of muscle group at pelvic floor muscle, to enhance the massage effect of pelvic floor muscle.

The invention relates to a repair composition for removing striae gravidarum as well as a preparation method and application thereof, and belongs to the technical field of cosmetics. The composition comprises the following components: Inca inchi seed oil, a Chinese holly extract, a grape seed extract, an areca flower extract, alligator oil, vitamin E and polydeoxyribonucleotide. All the components are coordinated to promote the proliferation of skin fibroblasts, so that the stretch marks can be reduced and faded. According to the preparation method, the polydeoxynucleotide in the composition is prepared into the nano-liposome, so that the transdermal performance of the composition is enhanced, the stability of the composition is effectively improved, the polydeoxynucleotide is promoted to be slowly released and stored in a skin care target part, and the bioavailability of functional components of cosmetics is effectively improved.

The application discloses an asymmetric bag type pneumatic artificial muscle and a manufacturing method thereof. The asymmetric bag type pneumatic artificial muscle comprises an upper film cloth, a lower film cloth, a plurality of air bags, a winding belt and a gas source system. The upper film cloth is overlapped with the lower film cloth. The air bags are sequentially arranged on the upper film cloth and located between the upper film cloth and the lower film cloth. The distance between the two side edges of the air bag and the lower film cloth is less than the length of the air bag along the outer surface. The winding belt sequentially passes through the upper film cloth and the lower film cloth and passes through each air bag. The two ends of the winding belt are fixed on the lower film cloth. The gas source system is communicated with the air bag. The air bag is formed by folding and heat sealing the upper film cloth and the additional film cloth on the upper film cloth. The expansion of the air bag only drives the expansion of the upper film cloth to form one-side expansion. The human body is directly contacted with the lower film cloth, so that the human body is avoided from being squeezed.
