The InviroSNAP!® Safety Syringe Flu Trays are designed specifically for institutions and companies that administer flu shots in bulk. The trays contain 25 3-ml, one-inch safety syringes and are available in case quantities with 40 trays in a case. The flu trays include the patented InviroSNAP! Safety Syringes. These syringes function like traditional syringes, but the device is engineered with a safety feature integral to the design. After using standard technique to administer a medication dose from the safety syringe, the clinician pulls the plunger back, causing the needle to retract inside the barrel. The plunger is then snapped off, permanently disabling the device. These easy-to-use syringes help hospitals and healthcare professionals reduce the incidence of needlestick injuries on the job, and can be especially critical in settings where flu shots and other vaccinations are being administered in bulk.
