Safety syringe system

A safety system for preventing accidental needle stick or infection for use with an instrument having a needle, comprising:

• an instrument having a cylindrical body comprising first and second ends, inner and outer walls, and a longitudinal axis, a needle having a base and tip, with the base of the needle being in communication with the second end of the body of the instrument;
• a protective cover having inner and outer walls, and first and second ends having needle entrance and egress apertures, respectively, said protective cover being configured to longitudinally envelope the base of the needle in a storage position, and engage and cap the needle tip in an protected configuration after the instrument has been utilized;
• activation means configured to urge said protective cover from said storage position to said un-reusable configuration upon the pressing of activation piece, said activation means being exterior to and longitudinally aligned with the body of the instrument, said activation means including
• a housing having first and second ends;
• inner and outer walls forming a cavity therethrough;

• bias means associated with said protective cover for urging said protective cover from said storage position to said unreusable configuration, urging said protective cover about the needle, toward the needle tip until said protective cover envelopes the needle tip;
• said bias means further comprising
• a shaft having first and second ends, said shaft longitudinally aligned with said instrument
• bias means for urging said shaft along a longitudinal path aligned with said instrument, generally toward said instrument tip, said bias means having first and second ends, said first end generally affixed to the cylindrical body of said instrument, said second end generally affixed to said shaft,
• lateral communication means for connecting said shaft to said protective cover,
• activation means for selectively initiating said bias means;
• and
• a cap locking hatch having first and second ends, said first end being configured to pliantly communicate with said protective cover in proximity to said second end of said protective cover, said cap locking hatch being configured to form a barrier juxtaposed to the needle tip and said egress aperture of said protective cover upon said needle tip being withdrawn into said protective cover.

A method of preventing accidental infection, comprising the following steps:

• (a) providing a safety system in conjunction with an instrument having a needle, comprising
• an instrument having a cylindrical body comprising first and second ends, inner and outer walls, and a longitudinal axis, a needle having a base and tip, with the base of the needle being in communication with the second end of the body of the instrument;
• a protective cover in longitudinal communication with said needle, said protective cover having inner and outer walls, and first and second ends having needle entrance and egress apertures, respectively, said protective cover being configured to longitudinally envelope the base of the needle in a storage position, and engage and cap the needle tip in a protected configuration after the instrument has been utilized;
• bias means associated with said protective cover for urging said protective cover from said storage position to said unreusable configuration, urging said protective cover about the needle, toward the needle tip until said protective cover envelopes the needle tip;
• said bias means further comprising
• a shaft having first and second ends, said shaft longitudinally aligned with said instrument;
• means for urging said shaft along a longitudinal path aligned with said instrument, generally toward said instrument tip, said bias means having first and second ends, said first end generally affixed to the cylindrical body of said instrument, said second end generally affixed to said shaft,
• lateral communication means for connecting said shaft to said protective cover,
• activation means for selectively initiating said bias means;
• and
• a cap locking hatch having first and second ends, said first end being configured to pliantly communicate with said protective cover in proximity to said second end, said cap locking hatch being configured to form a barrier juxtaposed to the needle tip and said egress aperture of said protective cover upon said needle tip being withdrawn into said protective cover,
• b. inserting said needle into a membrane, skin, or body of a patient;
• and
• c. protecting said needle, and lessening the possibility of infection by needle prick from said instrument after use, including the following steps
• i. applying force to said activation means,
• ii. selectively initiating said bias means, urging said shaft in a direction longitudinally aligned with said needle,
• iii. transmitting said bias means from said shaft to said protective cover via said communication means,
• iv. slidingly motivating said protective cover from said storage position about the base of said needle towards said needle tip until said protective cover envelopes said needle tip, withdrawing said needle tip from said needle aperture,
• v. blocking said needle aperture via said cap locking hatch.

A method of preventing accidental infection, comprising the following steps:

• (a) providing a safety system in conjunction with an instrument having a needle, comprising
• an instrument having a cylindrical body comprising first and second ends, inner and outer walls, and a longitudinal axis, a needle having a base and tip, and a length situated fully along the longitudinal axis of the body of said instrument, with the base of the needle being in communication with the second end of the body of the instrument;
• a protective cover in longitudinal communication with said needle, said protective cover having inner and outer walls, and first and second ends having needle entrance and egress apertures, respectively, said protective cover being configured to longitudinally envelope the base of the needle in a storage position, and engage and cap the needle tip in a protected configuration after the instrument has been utilized;
• bias means associated with said protective cover for urging said protective cover from said storage position to said unreusable configuration, urging said protective cover about the needle, toward the needle tip until said protective cover envelopes the needle tip;
• said bias means further comprising
• a shaft having first and second ends, said shaft longitudinally aligned with said instrument;
• means for urging said shaft along a longitudinal shaft path aligned with said instrument, generally toward said instrument tip, said bias means having first and second ends, said first end generally affixed to the cylindrical body of said instrument, said second end generally affixed to said shaft,

• activation means for selectively initiating said bias means;
• and
• a cap locking hatch having first and second ends, said first end being configured to pliantly communicate with said protective cover in proximity to said second end, said cap locking hatch being configured to form a barrier juxtaposed to the needle tip and said egress aperture of said protective cover upon said needle tip being withdrawn into said protective cover.
• b. introducing said needle of said instrument into a membrane, skin, or patient's body;
• c. prior to removing said needle from the membrane, skin, or patient's body, in order to protect said needle once it has been removed from the membrane, skin, or patient's body, and lessening the possibility of infection by needle prick from said instrument after use, the present method further includes the following steps
• i. applying force on said activation means,
• ii. selectively initiating said bias means, urging said shaft in a direction longitudinally aligned with said needle,
• iii. transmitting said bias means from said shaft to said protective cover via said communication means,
• iv. slidingly motivating said protective cover from said storage position about the base of said needle towards said needle tip until said protective cover communicates with the outer skin of the membrane, skin, or patient;
• v. removing said needle from the membrane, skin, or patient's body, while simultaneously allowing said bias means to further slidingly motivate said protective cover about said needle towards said needle tip as said needle is being removed from the membrane, skin, or patient, until the needle is completely removed and said protective cover simultaneously envelopes said needle tip upon removal, withdrawing said needle tip from said needle aperture, containing said needle and thereby preventing infection via needle prick with said needle.
