UNLABELLED Minimal inflation pressures are recommended for limb surgery to eliminate complications attributable to high inflation pressures with the pneumatic tourniquets. We applied controlled hypotension and a minimal inflation pressure (CHAMIP) technique to provide a bloodless surgical field. Thirty-six patients scheduled for upper extremity surgery were randomized equally to receive either ...

A straightforward and efficient anesthetic approach for hand forearm surgery is intravenous regional anesthesia (IVRA), often known as the Bier Block. Dr. August developed this method in 1908, it offers total well a bloodless operating room. Historically, local has been contained surgical field created by using an upper arm tourniquet. Major issues following IVRA with tourniquet are uncommon, a...

This project aims to Design and fabricate pneumatic arm for pick and place of cylindrical objects. The handling of materials and mechanisms to pick and place of objects from lower plane to higher plane and are widely found in factories and industrial manufacturing. There are number of pneumatic arms are available which consists of so many mechanisms hence becomes expensive. The designed pneumat...

In this paper, an intelligent Active Force Control (AFC) of a single-link Pneumatic Artificial Muscle (PAM) actuated robot arm employing Fuzzy Logic (FL) element has been applied and tested through an experimental study. The robot arm is desired to move along a one radian circular trajectory as a joint angle tracking control in the wake of the introduced disturbances. To demonstrate the practic...

Local compression is known to damage peripheral nerves. Severe compression may actually crush the fibres and lead to Wallerian degeneration; the excitability of the nerve distal to the lesion is lost and recovery may take many months (Seddon, 1943; Denny-Brown & Brenner, 1944 a). Mild compression produces a physiological block which is reversed as soon as the pressure is released. On the basis ...

BACKGROUND In upper limb surgery, the pneumatic tourniquet is an essential tool to provide a clean, bloodless surgical field, improving visualization of anatomical structures and preventing iatrogenic failure. Optimal inflation pressure to accomplish these objects without injuring normal tissue and inducing complications is not yet established. Use of the minimum tourniquet pressure necessary t...

BACKGROUND Up to 9% of casualties killed in action during the Vietnam War died from exsanguination from extremity injuries. Retrospective reviews of prehospital tourniquet use in World War II and by the Israeli Defense Forces revealed improvements in extremity hemorrhage control and very few adverse limb outcomes when tourniquet times are less than 6 hours. HYPOTHESIS We hypothesized that pre...

Presently artificial pneumatic muscles are used in various applications due to their simple construction, lightweight and high force to weight ratio. However, controls of various mechanical systems actuated by pneumatic muscles are facing various problems. The parameters of the muscles are nonlinear and time-varying due to temperature change and the deterioration of the pneumatic muscle materia...
