  • Publication number: 20210369695
    Abstract: Disclosed is a pharmaceutical composition containing dabigatran etexilate and a preparation method thereof. The pharmaceutical composition comprises a pharmaceutically active ingredient, dabigatran etexilate and/or dabigatran etexilate mesylate, and an polymer of polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol graft copolymer. The mass ratio of the two is 1:0.23 to 1:3. The pharmaceutical composition not only increases the bioavailability of the pharmaceutically active ingredient, but also reduces absorption variability, and provides a more stable concentration of dabigatran in plasma, thereby reducing adverse side effects.

    Abstract: A human condition detection device comprises a depth image-taking module for taking a depth image of a target area. A millimeter-wave radar module detects breaths or heartbeats in the target area to provide a signal. A thermal image-taking module takes a thermal image of the target area. A processor module determines whether a person is in the target area based on the depth image. The processor module determines whether there is any breath or heartbeat based on the signal if a person is in the target area. The processor module determines whether there is any abnormal vital sign of the person in the target area based on the signal and the thermal image if there is a breath or heartbeat in the target area. The processor module actuates the warning module to provide a warning if there is an abnormal vital sign of the person in the target area.
