    Abstract: A preparation method of a miniature intelligent calcium alginate hydrogel end operator based on different microelectrodes is introduced. The method includes an electrodeposition step of depositing a deposition solution under the action of a non-uniform magnetic field to form an anode surface; a processing step of transferring obtained hydrogel microstructures to a calcium chloride solution, making the hydrogel microstructure self-wind sufficiently; and a pickup step of collecting a self-winding single-layer film alginate microstructure in a culture dish, and placing it in specific environment for preservation. The preparation method can provide a degradable and convenient micro-operator, which could be locally prepared into different function components.

  • Patent number: 10879501
    Abstract: An ink drying process includes exhausting gas from atmosphere surrounding a substrate and drying ink through placing the substrate in a predefined pressure or less to form organic functional layers. Exhausting of gas includes: reducing, during a first period, pressure of the atmosphere from standard atmospheric pressure to a first pressure higher than vapor pressure of solvent having the highest vapor pressure among solvents of the ink; and subsequently reducing, during a second period, the pressure of the atmosphere to a second pressure lower than vapor pressure of solvent having the lowest vapor pressure among the solvents. Where pressure of the atmosphere is 10x Pa (X indicating a real number), a change amount average of X per unit time has a greater absolute value during the second period than during the first period.

  • Patent number: 10398442
    Abstract: Providing a stent which can easily be indwelled in a blood vessel in a state such that a catheter can be projected toward an inside of aneurysm. The stent is a stent for use in medical treatment of an aneurysm (1) and includes a cylindrical stent body (10) provided on a peripheral wall and having a plurality of insertion portions (11) through each of which a catheter (7) is insertable and a plurality of valving elements (20) provided in the insertion portions (11) respectively. Each valving element (20) is opened when the catheter (7) is inserted through one of the insertion portions (11). Each valving element (20) is closed when the catheter (7) is pulled out of the insertion portion (11). This suppresses an outflow into a blood vessel of a coil (9) placed in the aneurysm (1).
