Hospital employees, nurses, physicians, and laboratory personnel have long recognized the difficulties of obtaining blood samples from patients, particularly in pediatric and frail elderly patients. Time is spent looking for veins large enough or sturdy enough to withdraw blood specimens. With pediatrics, additional personnel are recruited to subdue uncooperative small patients for blood collection and then repeated for IV catheters or intramuscular injections. Many times, this causes stress on parents, as well as nurses and phlebotomists, aware that there is greater likelihood of needlestick injury with an uncooperative patient. Entirely eliminating the anxiety cannot be avoided, but One Stick™ will alleviate many of the problems associated with blood collection in pediatric and geriatric patients, and as a result, is safer for any patient in which it is used.
The One Stick™ allows blood to be removed (not drawn) from very small or fragile veins. Blood flows into this device utilizing only the patient's own intrinsic venous pressure. This prevents the premature collapse of veins due to the use of vacuum tubes and also avoids shearing of blood cells causing lysis, which may require the repeat of blood draws to obtain dependable lab values. Once an IV catheter is inserted, laboratory tests can be passively collected or medication and fluids can be administered intravenously rather than intramuscularly through the same tubing and catheter. This eliminates the needles used for subsequent intramuscular injections and laboratory blood collections. Even blood cultures can be obtained from 24 gauge catheters in scalp veins or foot veins of pediatric patients. All this, and only one needle is required!
