Description

Technical Field

[0001] This application relates to the field of pressure motion technology, and more particularly to a pressure detector. Background Technology

[0002] Compression training refers to the method of applying pressure to limbs using specialized compression straps to moderately control blood circulation, and then exercising under these conditions. Compression training is widely used in sports training, rehabilitation, medical monitoring, and health management. In sports training, pressure detectors are used to detect and control local muscle pressure to ensure training effectiveness is improved within safe thresholds. In rehabilitation, pressure detection devices can help patients with muscle function recovery training, especially during postoperative rehabilitation or muscle injury repair. By monitoring and adjusting the pressure applied to the muscles, it ensures that patients can train under appropriate loads, avoiding secondary injuries caused by overexertion. However, existing pressure detectors have the following problems:

[0003] 1. Existing pressure detectors typically use a single pipe to provide pressure regulation for multiple locations simultaneously. This design cannot provide differentiated pressure control for different locations and is prone to causing uneven pressure regulation.

[0004] 2. Existing pressure detectors rely on external power supplies, which limits their use in mobile or outdoor scenarios and makes it inconvenient for users to conduct training or rehabilitation in multiple scenarios.

[0005] 3. The existing pressure detector uses an integrated air tube to connect the device and the inflatable airbag. When the pressure training belt is unsuitable or when replacing an old or damaged air tube, the entire air tube must be replaced, which reduces the convenience of using the device. Utility Model Content
