Syringe needle description
BACKGROUND OF THE INVENTION
[0001] (a) Field of the Invention
[0002] The present invention relates to a safety device of a syringe
needle, and more particularly to a syringe in enhancing safety of
the medical treatment pragmatically by preventing the syringe needle
from being re-used and also avoiding a dangerous situation of being
stabbed.
[0003] (b) Description of the Prior Art
[0004] Referring to FIG. 6. A conventional syringe includes a hypodermic
needle 8 a needle seat 81 a syringe 9 and a lid 82 wherein, the
hypodermic needle 8 is formed in the front of the needle seat 81
connecting to the syringe 9 and the lid 82 is formed to enclose
the hypodermic needle 8 and the needle seat 81. To use the syringe,
hold the lid 82 to put the needle seat 81 in a nozzle 91 of the
syringe 9 and then detach the lid 82 to perform an injection, after
drawing medicament. After the injection, the lid 82 is to be re-capped,
a delicate action that a stab often happened to the nurse, causing
a burden psychologically for being infected with bacteria after
the stab. Furthermore, the re-capped needle may be detached from
the lid, due to a non-secured structure, which may hurt people who
dispose medical refuse. On the other hand, the used syringe may
still be undamaged and often be re-used in developing and under-developed
countries, which causes the spreading of contagious diseases.
SUMMARY OF THE INVENTION
[0005] The present invention relates to a safety device of a syringe
needle having a needle, a needle seat, and a needle lid. On the
needle seat, a circular groove formed in the front and a breakable
circular groove formed in the rear. At a rear end of the needle
lid, a semicircle ring is attached. To use a syringe, move the needle
lid backward to expose the needle. After injection, push the needle
lid forward to enclose the needle and insert the semicircular ring
into the circular groove to secure the needle lid and then snap
the needle seat from the breakable circular groove, thereby preventing
the needle from being re-used and enhancing the medical treatment
safety.
[0006] To enable a further understanding of the said objectives
and the technological methods of the invention herein, the brief
description of the drawings below is followed by the detailed description
of the preferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] Referring to FIGS. 1 and 2. The present invention relates
to a safety device of a syringe needle comprising a needle 2 a
needle seat 1 and a needle lid 3.
[0014] The needle seat 1 is a cylinder 10 wherein a cone 14 a
smaller ring 12 and a circular groove 13 formed in a row from the
front end. The needle 2 projecting forwards, is inserted into a
socket 11 formed in the rear of the cylinder 10 wherein, a connection
is formed by a breakable circular groove 103.
[0015] The needle lid 3 for the cylinder 10 is also a cylinder,
wherein, a projection ring 30 to be engaged with a the ring 12
formed on the inner perimeter and a semicircle ring 32 on a link
31 formed at the rear end, to be inserted into the circular groove
13.
[0016] Referring to FIGS. 3 and 4. Before using, the needle lid
3 is positioned in the front of the needle seat 1 to enclose the
needle 2 wherein the projection ring 30 of the needle lid 3 being
on the ring 12 is blocked by a base of the cone 14 thereby preventing
the needle lid 3 from moving away the needle seat 1. To use the
syringe, move the needle lid 3 backward to expose the needle 2.
After injection, push the needle lid 3 forward to the end to enclose
the needle 2 and also expose the circular groove 13 then, by bending
the link 31 backward down, to insert the semicircle ring 32 into
the circular groove 13 thereby firmly secured the projection ring
30 of the needle lid 3 between a base of the cone 14 and the semicircle
ring 32 preventing the needle lid 3 from moving backward. As such,
risk of being stabbed when re-capping the needle lid from the front,
as in the conventional syringe, is excluded.
[0017] Furthermore, the needle seat 1 can be broken, after using,
by snapping the breakable circular groove 103 thereby preventing
the needle 2 from being re-used.
[0018] In summary, the present invention is both advancement and
practicality in enhancing safety of the medical treatment by preventing
the needle from being re-used and also preventing a dangerous situation
of being stabbed.
[0019] It is of course to be understood that the embodiment described
herein is merely illustrative of the principles of the invention
and that a wide variety of modifications thereto may be effected
by persons skilled in the art without departing from the spirit
and scope of the invention as set forth in the following claims. |
