Abstract: To clarify the advantages of using soft robots in all aspects of life, the effective behaviour of the pneumatic muscle actuator (PMA) must be known. In this work, the performances of the PMA are explained and modelled with three formulas. The first formula describes the pulling force of the actuator based on the structure parameters; furthermore, the formula presented is the generalis...

Tourniquet application and its subsequent release cause serious injuries to the skeletal muscle, nerve, and neuromuscular junction (NMJ) due to mechanical compression and ischemia-reperfusion (IR). Monitoring structural and functional repair of the NMJ, nerve, and skeletal muscle after tourniquet-induced injuries is beneficial in exploring potential cellular and molecular mechanisms responsible...

This paper presents the novel design of an ambidextrous robot arm that offers double range motion as compared to dexterous arms. The is unique in terms (ambidextrous feature), actuation (use two different actuators simultaneously: Pneumatic Artificial Muscle (PAM) and Electric Motors)) control (combined use Proportional Integral Derivative (PID) with Neural Network (NN) Multiple Adaptive Neuro-...

On the battlefield, a properly applied tourniquet can be an extremely effective means of controlling severe extremity wound hemorrhage. However, a great deal of confusion exists among soldiers, medics, and military medical officers on a number of tourniquet-related issues. What is an appropriate combat tourniquet? When is it appropriate to use a tourniquet? When and by whom should a tourniquet ...

BACKGROUND Fibroids remain the commonest pelvic tumour seen in women with myomectomy being the major form of treatment in our environment. Techniques to minimize blood loss will reduce patient morbidity and the need for blood transfusions. One such technique is the use of a tourniquet during myomectomy operation. This study examines the effectiveness and safety this tourniquet technique. METH...

UNLABELLED The mechanism of tourniquet-induced arterial pressure increase is not known. We investigated the effect of preoperative ketamine on tourniquet-induced arterial pressure and heart rate changes in 85 patients undergoing knee surgery with a tourniquet under general anesthesia. Patients were randomly assigned into three groups; Large Ketamine (n = 28; ketamine 1.0 mg/kg), Small Ketamine ...

BACKGROUND The aim of this study is to evaluate the effects of tourniquet release before wound closure for hemostasis or after wound closure in cemented total knee arthroplasty (TKA). METHODS We conducted a meta-analysis and review work on relevant clinical outcomes to evaluate the effects of the timing of tourniquet release in cemented TKA. Electronic databases were searched for relevant ran...
