Introduction:
The development of this device is basically to wrap around the forearm of the patient and it will provide accumulated pressure around the forearm. This device is non-pneumatic thus it will not use any air pressure or pump to operate. Current device use in the market of biomedical department is intermittent pneumatic compression (IPC) device, it use air pressure to compresses the limbs. Theoretically, an ideal compression device will compress sequentially (distal to proximal) and will have a pressure gradient (highest pressure distal and lowest pressure proximal). This is where an appropriate solution of using non-pneumatic device will wrap and tighten around the patient forearm due to the rotation of few wheels. Each of the wheels will be holding by its own strap as it will be connected together. Noted here each wheel will have totally difference circumference and will create different pressure.
Problem Statement:
Deep vein thrombosis (DVT) and the possibility of a subsequently occurring pulmonary embolism is a dangerous condition that can occur in legs as a result of long periods of immobility, the hypercoagulability precondition, damaged endothelial cells of the circulatory system. Current compression devices used to prevent DVT involve pneumatic compression of the legs or feet by devices that are often bulky and noisy. Compression of the foot can be painful because of the high pressure required. Persons of a higher body mass index (BMI) can have trouble fitting current devices on their lower extremities.
Function:
The design should compress the forearm from the wrist to the elbow for 10 seconds per minute at 50 mm Hg. The design must also provide minimal patient discomfort (noise, pain, and/or bulkiness and ease of use). The design should be able to connect to a battery pack and be adjustable for
