摘要： A medical safety injector includes: a needle hub connected with a needle; a hollow barrel for retaining the needle hub and, upon completion of an injection, guiding the needle hub to retract into the hollow barrel; and a plunger combination disposed within the hollow barrel. The plunger combination includes a retractable plunger and a hollow shank partially muff-coupled with the retractable plunger. The retractable plunger has an exterior sidewall formed with at least one protrusion in a muff-coupled region with the hollow shank, for being correspondingly snap-fitted with at least one recess formed on an interior sidewall of the hollow shank. If a user continues to apply a force to the plunger combination after the medical safety injector accomplishes an injection, the retractable plunger will retract smoothly into the hollow shank to free space in the hollow barrel for receiving the needle hub, thereby improving single-handed operability of the injector.

摘要： A retractable safety syringe includes a retractable needle hub holding a needle and having a first guiding means; and a hollow barrel having a second guiding means set correspondingly to the first guiding means; and a collapsible plunger comprising of a first plunger element having a protrusion releasably coupled with a second plunger element having a longitudinal slot with a pinched zone to curb the movement of said protrusion; and a spring disposed between the needle hub and hollow barrel and acts between the needle hub and the hollow barrel. The uncoupling of the collapsible plunger triggers the retraction mechanism to enable the needle hub to retract into the barrel by the decompression force of a spring. The reliability of retraction is further improved by a longitudinal slot and a protrusion to facilitate the retreating of the collapsible plunger in an orderly way.

摘要： A SAFE MEDICAL-DRUG INJECTOR (1) WITH A COLLAPSABLE PLUNGER COMBINATION (14) THEREOF IS PROPOSED. THE INJECTOR (1) INCLUDES A HUB (11) CONNECTED WITH A NEEDLE (10), A HOLLOW BARREL (12), AND A COLLAPSABLE PLUNGER COMBINATION (14) INCLUDING A HOLLOW CANNULA (16) AND A RETRACTABLE PLUNGER (15) THAT IS TELESCOPED WITH THE HOLLOW CANNULA (16). AT LEAST A STRESS ADJUSTABLE NOTCH (151) IS FORMED AT THE CORE OF THE RETRACTABLE PLUNGER (15) OR IN AN UPPER EDGE OF THE HOLLOW CANNULA (16), AND AT LEAST ONE RAISED PORTION (150) IS FORMED ON AN OUTER LATERAL SIDE OF THE RETRACTABLE PLUNGER (15) NEAR THE STRESS ADJUSTABLE NOTCH (151) TO BE CORRESPONDINGLY EMBEDDED WITH AT LEAST A DEPRESSION (160) FORMED ON AN INNER LATERAL SIDE OF THE HOLLOW CANNULA (16). THE ENGAGEMENT BETWEEN THE RAISED PORTION (150) AND THE DEPRESSION (160) IS RELEASED TO MAKE THE RETRACTABLE PLUNGER (15) DRAWN BACK TO THE HOLLOW CANNULA (16) WHEN A FOLLOWING PRESS IS APPLIED ON THE HOLLOW CANNULA (16) AFTER THE SAFE MEDICAL-DRUG INJECTOR (1) COMPLETES AN INJECTION.

摘要： A retractable safety syringe (1) includes a retractable needle hub (4) holding a needle (40) and having a first guiding means (42), a hollow barrel (2) having a second guiding means (22) set correspondingly to the first guiding means (42), a collapsible plunger (6) comprising a first plunger element (64) having a protrusion (603) releasably coupled with a second plunger element (62) having a longitudinal slot (602) with a pinched zone (6021) to curb the movement of said protrusion (603), and a spring (8) disposed between the needle hub (4) and the hollow barrel (2) and acts between the needle hub (4) and the hollow barrel (2). The uncoupling of the collapsible plunger (6) triggers the retraction mechanism to enable the needle hub (4) to retract into the barrel (2) by a longitudinal slot (602) and a protrusion (603) to facilitate the retreating of the collapsible plunger (6) in an orderly way.
