SELF-RETAINING INTRAVENOUS NEEDLE PLATE

Numerical Analysis Stability of Retaining Wall with Relieving Plate

Based on shear strength reduction finite element method, stability of retaining wall with relieving plate has been analyzed. Due to the structure character of retaining wall with relieving plate, it can be found that fracture surface could hardly cross the triangle area of between lower wall and soleplate, between upper wall and relieving plate, so the second fractured surface occurred at there...

Needle embolism in intravenous drug abuse

Although intravenous drug users report the breaking of a needle as a relatively common occurrence, central embolism of needle fragments occurs infrequently in the literature. Central needle embolism also poses a conundrum for the radiologist, as the needle may be easily overlooked when the clinical history is nonspecific. We present two cases of needle embolism to the lung, one complicated by i...

Self-Retaining Contact Lens Simplifies Intravitreal Injection Course in Rats

BACKGROUND The aim of this study was to design a self-retaining rat contact lens to simplify intravitreous injection in rats. MATERIAL/METHODS A self-retaining, plane-concave prism contact lens customized for rats was designed. Forty diabetic rats were randomly divided into 2 groups and received the intravitreous injection of 10 μl of a cell suspension containing bone marrow-derived stroma ce...

Self-retaining lip retractor for use with the Macintosh laryngoscope.

Dear Sir, In the April 1950 edition of your Journal, Dr. Esplen illustrated a metal anaesthetic screen for use in thoracotomies in the lateral position. I agree that such a screen is essential to maintain a good view of the patient's airway, and more particularly to facilitate bronchoscopy without disturbing the operative field should it become necessary during operation. Such a screen can well...
