This protocol describes a rod-based approach, combining 3D-printing and soft lithography techniques for fabricating the soft gripper devices. This approach eliminates the need for an external air source by incorporating a chamber component and reduces the chance of occlusion during the sealing process, particularly for miniaturized pneumatic channels.

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA There are two distinct stages in a construction project involving concrete. The first stage involves batching, transporting, and casting fresh concrete. At this stage, the material is viscous, and the workability and finishability are the key performance criteria. The second stage occurs when the hydration process begins shortly after the concrete is placed in the form, and the concrete will...

This protocol presents the configuration of a compression test device capable of precisely measuring the mechanical properties of microstructures in the small-strain region, along with a systematic method for compression testing using this device. The proposed device can be used to analyze various microstructures and the mechanical behavior of polymer-based materials.
FAQs
The sleeves inflate in an ordered sequence, beginning around more distal limb regions and progressing toward proximal areas. This patterned pressure encourages blood to move back through the veins rather than remaining pooled in dependent parts of the limb. The sequential design is therefore central to reducing venous stasis, particularly when limited mobility reduces the normal circulatory benefit of movement.
Periodic inflation and release create repeated pressure changes instead of continuous compression. These rhythmic cycles support recurring movement of venous fluid and help limit prolonged stagnation or fluid accumulation in surrounding tissues. Automated cycling also provides a consistent treatment pattern, while adjustable pressure allows the therapy to be adapted to the clinical situation rather than delivered as one fixed level.
Intermittent Pneumatic Compression addresses venous stasis through externally applied, sequential pressure, whereas mobility and anticoagulation contribute through different clinical approaches. The method can therefore serve as a practical complement when patients have limited movement or when care includes other measures. Its role is supportive within a broader plan rather than a replacement for mobility, anticoagulation, or other appropriate treatments.
An inflatable sleeve is placed around the affected limb, and its chambers periodically inflate and deflate according to automated cycles. Pressure is applied sequentially along the limb, commonly progressing from distal toward proximal regions. Adjustable settings determine how the pressure is delivered, allowing the device to provide repeated mechanical support for venous return and control of tissue swelling.
Clinicians may use this approach to help prevent deep vein thrombosis in patients whose mobility is limited. Reduced movement can contribute to venous stasis, while the device supplies repeated external pressure to encourage venous return. In clinical care, it may be incorporated alongside mobility, anticoagulation, and other treatments when those measures are appropriate for the patient.
For lymphedema or other circulatory conditions associated with swelling, repeated chamber inflation can help limit fluid accumulation in surrounding tissues. The adjustable pressure and automated sequence provide a controlled way to apply this support to the limb. This makes the approach relevant not only to thrombosis prevention, but also to clinical management of tissue swelling linked to impaired circulation.
