An Improved Syringe for Injecting Precise Amounts
The method described by Rosenau 1 for injecting precise amounts of fluids into animals is excellent. In the practical application of this method certain difficulties have however been encountered, which, it is believed, can be overcome by improvements in the syringe herein described. The time reqtfired for removing the bulb of and measuring the salt solution into the syringe to wash i t out, af...
متن کاملAn Improved Urethral Catheterization in Female Pigs: A Pilot Study
With the popularity of urine flow dynamic monitoring and indwelling catheter technologies in animal experiments, the urethral catheterization has become a common technique in scientific research. The miniature pig is considered as one of the major animal species used in scientific research and is increasingly being used as an alternative to a dog or monkey as the nonrodent species of choice in ...

A rare case of anterior urethral valve in association with posterior urethral valuve is reported. Clinical findings are discussed, and the available literature will be briefly reviewed.
متن کاملDownward movement of syringe pumps reduces syringe output.
We studied how lowering a syringe pump and changing the outflow pressure could affect syringe pump output. We experimentally reduced the height of three different syringe pump systems by 80 cm (adult setting) or 130 cm (neonatal setting), as can happen clinically, using five flow rates. We measured the time of backward flow, no flow and the total time without flow. An exponential negative corre...
متن کاملSyringe-injectable electronics.
Seamless and minimally invasive three-dimensional interpenetration of electronics within artificial or natural structures could allow for continuous monitoring and manipulation of their properties. Flexible electronics provide a means for conforming electronics to non-planar surfaces, yet targeted delivery of flexible electronics to internal regions remains difficult. Here, we overcome this cha...
