2results about How to "No aging" patented technology

The invention discloses a treadmill with a force measuring function, and belongs to the technical field of sports and fitness equipment. The problems that in the prior art, measurement experiment data are tedious, and calibration needs overall inspection are solved. According to the technical scheme, a frame is installed on a bottom plate, a handrail is installed at the front end of the frame, a treadmill body is arranged in the frame and does not make contact with the frame, and four balance structures are arranged between the treadmill body and the frame and distributed in a rectangular shape; the measuring end of the balance structure is connected with the treadmill body through a spherical hinge mechanism, and the mounting end of the balance structure is fixed to the frame. In the force measurement process, the force sensor has excellent linearity and sensitivity, keeps long-term stability in an extremely wide measurement range, can precisely measure each quick action, has high resolution and reliability, has relatively high sensitivity, is high in overload resistance, long in service life and free of aging, and meanwhile, reduces the equipment detection cost and reduces the maintenance difficulty.

This invention discloses a vibration-type respiratory sputum clearance device, relating to the field of medical device technology. It includes a vest body. Multiple independent liquid-coupled vibration units are arranged on the inner side of the vest, corresponding to the upper and lower lobes of both lungs and the projected lung region on the back. Each liquid-coupled vibration unit includes a sealed liquid-sealed bag, and a vibration unit is disposed on the outer side of each sealed liquid-sealed bag. The sealed liquid-sealed bag is integrally embedded and fixed in a flexible interlayer on the inner side of the vest. The interior of the sealed liquid-sealed bag is filled with a vibration-transmitting liquid. The vibration-transmitting liquid filled in the sealed liquid-sealed bag of this invention, relying on its incompressible and highly fluid physical properties, can efficiently transmit and convert the high-frequency micro-vibrations generated by the double-layer piezoelectric sheet, forming a dual mechanical action of shallow loosening and deep oscillation, perfectly adapting to the sputum clearance needs of the soft tissues of the chest and back and the deep airways of the thoracic cavity.
