Instances of disease outbreaks as a result of syringe
reuse have cropped up over the past several years in various states, including Connecticut (in 1997), New York (2001 and 2007), Nebraska (2002), Oklahoma (2002), Indiana (2007), and Nevada (2008).
For everyday blood gas analysis a plastic syringe
kept at room temperature and analyzed within 30 minutes is recommended.
are designed to be easily filled at the distal end of the syringe
and can be used with viscous materials.
"It is also notable that a local drug user organization opened a syringe
exchange program at the time of the policy change, and eventually peer involvement in the delivery of the syringe
exchange program became the standard locally," researchers wrote.
Jack Dillard, COO and inventor of the Protectus/SquareOne Medical Safety Syringe
and its family of safety needle devices, said, "The key elements of this patent provide coverage for the spring responsible for the automatic deployment of the Protectus safety technology that keeps users, patients and other healthcare workers safe during and after use without having to perform any conscience action."
First, and perhaps most importantly, their report highlighted a batch fault, as other syringes
from the same batch were checked and all flanges were found to be loose and easily detached from the main glass syringe
Backflow into the syringe
contaminates the syringe
From a pharmaceutical point of view, the syringe
needs to be closed as soon as possible after filling, thereby minimizing the risk of contamination.
Although the syringe
has a plunger, electrospinning isn't an extrusion method.
In December 2002, staff from Beth Israel Medical Center (BIMC) in New York City and the North American Syringe
Exchange Network (NASEN) mailed surveys about syringes
exchanged and returned, services provided, and budgets and funding to the directors of all 148 SEPs known to NASEN (compared with 154 known SEPs for the 2000 survey, 131 for 1998, 113 for 1997, 101 for 1996, and 68 for 1994-95) (2-5; BIMC, unpublished data, 2000).
Consisting of two separate experiments, in the first volumes of syringe
water (0, 0.05, 0.1, 0.7, 1.4, 2.7, 4.1, or 5.5 mm) were applied at 1100 or 1300 h.
Unlike diaphragm pumps, which propel their contents by means of a mechanically controlled barrier, and the strong-selling peristaltic pumps, which squeeze measured amounts of fluid through flexible tubes with roller-tipped spokes, syringe
pumps use common laboratory objects.
