Apheresis is an essential step in clinical diagnostic. Searching for a safe and fast way was necessary to avoid wasting time and obtain the desired results efficiently. This research includes two stages: First, a microfluidic biochip with the properties of fast processing response, automation capability, and low-cost was designed having a tiny mesh-type channel that filters pure plasma from the blood components and a straight channel to deliver the pure plasma to a tank. Second, an automated system was designed to detect blood calcium levels using a microcontroller and a colors-detection sensor TCS3200-DB. The device is designed to take a 0.15 to 2.15 mg/dL, 10-160 μm blood sample, which is considered small compared to the samples taken for the blood apheresis process used in laboratories where a substantial quantity of pure plasma is obtained naturally. Pure plasma is mixed with calcium detectors R1 and R2 to get a violet-colored solution with a wavelength between 390 nm to 440 nm. The results of the proposed device were compared with the traditional methods used spectroscopy method using concentrations of 10 different blood samples, and the results proved that there is a slight error between the two processes.
Electromagnetic field smart splint for bone fixing and rehabitation using niti shape memory alloy

Patients who suffer from broken bone co uld be prescribed splints to support their treatment procedures. The normal fabrication style of tailored splints is talent dependent long and also the splints themselves create varied issues with regards to the patient's response. Between many different special characteristics of Shape Memory Alloys (SMAs) that they have the power to come to an original form once heated. However, the general modification of associate degree existing part will powerfully be affected by the thermal and thermo-s mechanical properties. Therefore, shape memory alloys have been discovered numerous materials, which may typically be classified into Nobel-metal based mostly, Cu based, Fe based, NiTi alloy based system and metalloid shape memory alloys. Electrical stimulation has been applied to a number of different ways to influence tissue and bone healing. Most of the early works were carried out by orthopedic surgeons looking for new ways of enhancing fracture healing, especially those fractures that had developed into nonunion. Electrical energy can be supplied to a fracture by direct application of electrodes or inducing current by use of pulsed electromagnetic field or capacitive coupling. Many of these techniques have not been standardized.
