ABSTRACT:
This invention relates to a combination needle shield
eedle guard device that is positively locked onto detachable needle assemblies for an evacuated blood collection system and for a hypodermic syringe. More particularly, this invention can: (1) function as a needle shield to enclose and prevent contamination of the sterile needle to be used for a medical procedure; (2) function as a needle guard which can slide on a length extension for either needle assembly, such that the needle can be uncovered or re-covered in a direction from behind the needle point, thereby providing a safety feature for the operator who can avoid direct contact with a used, blood-contaminated needle point. Avoidance of direct contact with used needle points will reduce the likelihood of contracting blood-borne infections such as AIDS, infectious hepatitis, syphilis etc. that might occur following accidental puncture with contaminated needles; (3) provide improved securing for an evacuated blood collection system between the double-ended needle assembly and the container holder, thereby preventing the double-ended needle assembly from unlocking with the container holder during the process of withdrawing blood into an evacuated container and (4) improve blood withdrawing success with the blood evacuated collection system and with a large volume syringe. This occurs by the addition of a length extension which separates the wide girth of the container holder or the wide girth of a large volume syringe barrel from close approximation to the needle used for withdrawing blood, thereby permitting more shallow or acute angle access of needle entry into a blood vessel during blood withdrawing procedures.
