Blood flow stimulator for enhancing limb circulation
The granted patent US12011416B2 describes a blood flow stimulator designed to enhance blood circulation in a patient's limb. The device features a housing that can be sealed around the limb, creating a controlled environment within a designated volume. This housing includes two seals: the first segregates the internal volume from the external environment, while the second divides the internal volume into two sections. The device is equipped with multiple conduits, including a first conduit that connects to an external blood filtration circuit, and additional conduits that communicate with the two internal sections. A force generator is integrated into the system, which creates a pressure differential to apply force on the skin, thereby promoting blood flow.
Further enhancements to the blood flow stimulator include a controller with processing circuitry that regulates the force generator based on various physical or physiological parameters, such as the patient's respiratory cycle. The force generator may consist of a pump, adhesive, or suction cup to achieve the desired pressure differential. The housing is designed to transition between open and closed configurations, facilitated by a hinge mechanism, and includes a locking mechanism to secure it in place. The patent also encompasses the inclusion of a blood filtration circuit, emphasizing the device's comprehensive approach to managing blood flow and filtration in a clinical setting.
