Combination needle shield/needle guard device positively locked onto detachable needle assemblies for an evacuated blood collection system and a hypodermic syringe

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