OBJECTIVE To determine to what extent FPs teach and use pneumatic otoscopy and to identify the chief influences on this behaviour. DESIGN Mixed-methods descriptive study conducted between March and May 2011. SETTING The family medicine residency program at Laval University in Quebec city, Que. PARTICIPANTS Directors of the family medicine teaching units (FMTUs), teachers, and residents. ...

There has been increased interest in use of pneumatic actuators in many fields, such as medical care and welfare. In particular, proposed pneumatic soft actuator with soft material has many advantages such as low mass, flexibility, safety and user-friendliness. We therefore focus on the pneumatic actuators as a drive source of a rehabilitation device. This paper describes the concept, design, p...

conclusions: administration of α-1a-specific blocker reduced analgesic dosage and colic episodes and rate of adverse effects after ureteroscopic lithotripsy of lower ureteral stones and decreased gravel expulsion time after ursl. results: the results showed that tamsulosin treatment group had low expulsion time (p = 0.011), low urinary tract symptoms, least analgesic needs and low adverse effec...

In this contribution, three nonlinear control strategies are presented for a two-degree-offreedom parallel robot that is actuated by two pairs of pneumatic muscle actuators as depicted in Fig. 1. Pneumatic muscles are innovative tensile actuators consisting of a fibrereinforced vulcanised rubber hose with appropriate connectors at both ends. The working principle is based on a rhombical fibre s...

An experimental study concerning particle behaviors in a horizontal dilute swirling flow pneumatic conveying was performed. Measurements of particle velocities and concentration profiles have been carried out using the photographic image technique. From the experimental results, it is found that mean particle velocity of swirling flow pneumatic conveying is lower than that of conventional pneum...

One strategy for actuating soft machines (e.g., tentacles, grippers, and simple walkers) uses pneumatic inflation of networks of small channels in an elastomeric material. Although the management of a few pneumatic inputs and valves to control pressurized gas is straightforward, the fabrication and operation of manifolds containing many (>50) independent valves is an unsolved problem. Complex p...

The objective of this paper is to present the methods of development and study of control law of rodless pneumatic actuator with fuzzy regulator in order to improve the accuracy of the pneumatic drive carriage positioning. The basis for improving the accuracy of positioning of the pneumatic actuator is the Intelligent Control System.

This paper reports on existing and novel transducers for improved quantitative investigations of the levels of applied pressures and pressure gradients produced on human limbs by non-pneumatic tourniquet straps, and by non-pneumatic elastic bandages and elastic rolls when used as tourniquets, for comparison to benchmark data for pneumatic tourniquet cuffs commonly used in surgery at present.

The structure and morphological change of the excretory gland in the mucous membrane of the maxillary sinus was studied and discussed on the structural principles of these pneumatic csvity found by Goto and his co-workers. 1. The excretory gland of the maxillary sinus is a tubulo-cellular gland consisted of the tubar and cavitary part, and the latter is further divided into the tubular and cell...
