This paper investigates axial compression process of multi-layered tubes with circular cross-section under the axial loading in the quasi-static condition using experimental method. Some specimens are prepared in seven different groups, namely; empty carbon/epoxy composite tubes, solid carbon/epoxy composite rods, empty copper tubes, composite tubes with silicon sealant filler, concentrically s...

In a patient in whom it was initially difficult to pass the duodenojejunal junction, a long decompression tube was easily inserted using double balloon endoscopy. The patient was a 16-year-old male with bowel obstruction who had undergone proctocolectomy for ulcerative colitis. A double balloon endoscope was inserted into the jejunum about 50 cm from the ligament of Treitz. A stiff hydrophilic-...

Tracheobronchial disruption is an uncommon but severe complication of double lumen endotracheal tube placement. The physical properties of a double lumen tube (large external diameter and length) make tracheobronchial injury more common than that associated with smaller single lumen endotracheal tubes. Here we present the case of an iatrogenic left main bronchus injury caused by placement of a ...

A double curved nasal endotracheal tube has been incorporated into a standard head drape [or improved access and visibility when providing dental treatment [or the young patient under general anesthesia. The technique [or stabilization o[ the airway to provide sa[ety and protection o[ the patient is described in detail. This method has been used successfully [or over 100 dental patients. All pa...

By using a microphone to provide the input, the standard Cossor-Robertson cardiograph can be used to record heart sounds instead of the electrocardiogram, but such a record is of little value unless it is recorded synchronously with an electrocardiogram. For this purpose two separate recording channels are necessary. The double-beam cathode ray tube with two amplifying channels has been develop...
