3results 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.

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.
