NEW URETHRAL SYRINGE.

The syringe gap: an assessment of sterile syringe need and acquisition among syringe exchange program participants in New York City

BACKGROUND Programmatic data from New York City syringe exchange programs suggest that many clients visit the programs infrequently and take few syringes per transaction, while separate survey data from individuals using these programs indicate that frequent injecting - at least daily - is common. Together, these data suggest a possible "syringe gap" between the number of injections performed b...

New disposable plastic syringe for collecting and centrifuging blood.

Collecting blood for haematological and biochemical analysis is not as simple a task as it may seem to be. It must be carefully conducted, and the handling of blood after collection must be reduced to a minimum to avoid changes in its composition. Glass syringes used for this purpose are now largely replaced by disposable plastic syringes. Since the plunger provides a good seal it excels the gl...

ANTERIOR URETHRAL VALVE ASSOCIATED WITH POSTERIOR URETHRAL VALVE

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.

New Device for Obtaining Subcutaneous Tissue Specimens: the Aspirating Syringe.

Downward 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...
