5results about How to "Improve isolation efficiency" patented technology

The invention discloses an isolation chip and an isolation system. The isolation chip includes a primary side frame, a secondary side frame, a first die, and a second die. The first tube core is connected with the primary side frame, the second tube core is connected with the secondary side frame, and the primary side frame and the secondary side frame form a three-tap transformer. According to the three-tap transformer, the frame body of the isolation chip serves as the three-tap transformer, the frame body has a larger sectional area, the coil direct-current impedance can be directly reduced, heat loss in the current transmission process is reduced, electromagnetic interference can be restrained through differential transmission of the three-tap isolation coil, and the isolation efficiency is improved.

The utility model discloses a telescopic rod piece and modularization quick assembly apron for shock insulation ditch, set in the top of shock insulation ditch, include: support beam, parallelly arranged two, and both ends are used for hinged connection with the structure connection, support beam is telescopic structure, support rod piece, install on support beam and along the length direction of support beam and set side by side multiple groups, support rod piece with support beam swing joint, make the support rod piece interval can be relatively staggered. The application is through the pin shaft hinged joint node and the flexible apron component cooperation design, ingenious use parallelogram unstable characteristics, through linkage between the rod piece and the rod piece, realize the telescopic between the rod piece, realize the apron in horizontal and vertical two -way self -adaptation displacement, have when the earthquake and not easy to take place the upwarp, threaten personnel safety and the strong carrying capacity, can satisfy the demand of passing through the person, passing the car.

The present invention belongs to the technical field of membrane structure buildings, and particularly relates to an internal circulation energy-saving system for membrane structure buildings, comprising a platform component with an automatic inflation function, a membrane structure component with an airtight protection function, a foundation beam component with a detection function, and a solar energy component with an airflow internal circulation function; the platform component is a rectangular structure, and the foundation beam component is fixedly connected to the top of the platform component, and the foundation beam component is a grid-shaped hollow structure. The solar energy component is around the membrane structure component, absorbs solar energy at different angles throughout the day and converts it into electrical energy, provides power for electrical equipment in the membrane structure building, and can also transport the airflow to different positions in the membrane structure component, and cooperate with the foundation beam component to form an internal circulation of the airflow, thereby improving the energy-saving effect of the internal circulation of the airflow in the membrane structure building.

The utility model relates to a two-way belt outlet warning device with an acousto-optic warning function, which belongs to the technical field of the two-way belt outlet warning device with the acousto-optic warning function and comprises a box body, two warning mechanisms are arranged on the box body in a left-right mode, and a magnetic base is arranged on the rear side of the box body. The warning mechanism comprises an opening, a warning tape, a winding roller and a limiting fastener, the opening is formed in one side of the box body, the warning tape penetrates through the opening, the winding roller is arranged in the box body and rotationally connected with the box body, the limiting fastener is located outside the box body, one end of the warning tape is fixedly wound on the winding roller, and the other end of the warning tape is fixedly wound on the limiting fastener. The other end of the warning tape is sleeved on the limiting fastener; the two warning tapes are drawn out at the same time, the isolation efficiency is improved, the magnetic base, the hook-and-loop fastener and the support connecting base are arranged on the box body, the device can be suitable for different occasions, and the application range is widened.

This invention belongs to the field of medical device technology. It discloses an adjustable video bronchial isolation catheter, comprising a ventilation catheter for inserting into a patient's bronchus to block and isolate the ipsilateral lung, and which, when necessary, is also used for ventilation, aspiration, and flexible bronchoscopy; and a video device mounted on the ventilation catheter. The distal portion of the ventilation catheter has a central axis deviation forming a bend, constituting a bend section of the tube. The camera of the video device is located at the junction of the proximal end of the bend section and the adjacent tube at that end, providing a wide field of view for guiding the insertion of the ventilation catheter and for positioning and dynamic monitoring of the catheter. This invention has the advantages of guiding and positioning the insertion of the bronchial isolation catheter to reduce airway damage to the patient, and dynamically monitoring the use of the bronchial isolation catheter.
