Safety syringe with self-sealing needle retraction and retracted member lock

A safety syringe with self-sealing needle retraction and retracted member lock comprising:

• a syringe cylinder having a plunger end, a needle end, an outer surface and an inner surface, also having an integral cylinder portion extending from the plunger end to a cover point and an integral tapered portion extending from the cover point to the needle end, the needle end of the syringe cylinder defining a syringe needle slot for aligning a partially inserted needle along a longitudinal axis within the syringe cylinder;
• a securing ring affixed to the needle end of the syringe cylinder, the securing ring defining a ring needle slot sized and aligned commensurate with the syringe needle slot for releasingly securing and aligning a partially inserted needle along a longitudinal axis within the syringe cylinder;
• a tubular needle means for transferring fluids between a patient and the syringe cylinder comprising an integral shank abutting an integral enlarged needle head, the needle means being partially inserted into the syringe cylinder such that the needle head extends within the cylinder portion of the syringe cylinder and the shank extends outwardly from the securing ring, to which the needle means is releasingly affixed, during such transfer of fluid;
• a plunger reciproactively held in the syringe cylinder for boosting a fluid medicine in the syringe cylinder to be injected into and drawing fluid from a patient through the needle means, the plunger having a front surface, the front surface defining a needle clamp securingly engageable with the needle head such that full depression of the plunger causes such engagement and subsequent retraction of the plunger further causes dislodging and retraction of the needle means;
• a locking clamp affixed proximate to the plunger end of the inner surface of the cylinder portion of the syringe cylinder for engaging and restraining a sufficiently retracted plunger from subsequent depression;
• and
• a sealing means comprising a cover shaped to essentially conform with the front surface of the plunger and secured about its circumference to the inner surface of the syringe cylinder proximate to the cover point, the cover and the inner surface of the tapered portion of the syringe cylinder defining a sealant cavity containing a conventional liquid repelling sealing compound, the cover further defining a cover needle slot sized and aligned commensurate with the syringe needle slot, such that the sealing compound is drawn into a needle cavity defined by a retracting needle while mixture of the sealing compound with fluid within the syringe cylinder is prevented.
