Safety syringe abstract
A simply and easily used safety syringe cap comprises a first cap,
a second cap overlapped on the first cap. The first cap serves for
sealing a syringe before being used so as to protect the syringe
needle. At an opening of the second cap is formed with a trench
along a longitudinal direction of the cap. Two sides of the trench
are folded outwards to form the sliding pieces. Thereby, after the
syringe needle is used, it may be guided into the second cap along
the lateral directions of the sliding pieces. The trench is gradually
reduced along the opening of the second cap. Thereby, the syringe
needle can be guided into the cap by its lateral side to avoid hurting
the user.

Safety syringe description
FIELD OF THE INVENTION
[0001] The present invention relates to articles and instruments
for medical use, and particularly to a syringe cap which including
a first cap and a second cap, in that a syringe needle can be guided
into the cap along sliding pieces.
BACKGROUND OF THE INVENTION
[0002] It is possible that a used syringe needle prinks the medical
personnel due to a careless operation. However, this is dangerous,
since it is possible that the syringe needle is infected by germs
or virus, especially, AIDS, hepatitis, etc. If the syringe needle
with these germs or viruses is prinked into a human body, it will
induce that the body is infected.
[0003] Therefore, some safety syringe needles are developed for
improving this defect. However, most of these designs are expensive
and has a complicate structure. The complexity of the structure
will induce the parts of the syringe needle are tightly engaged
and thus cannot work normally. Furthermore, the syringe needle will
be destroyed after being used once and thus cannot be used repeatedly.
Therefore, this prior art design does not be used widely.
SUMMARY OF THE INVENTION
[0004] Accordingly, the primary object of the present invention
is to provide a simply and easily used safety syringe cap comprises
a first cap, and a second cap overlapped on the first cap. The first
cap serves for sealing a syringe before being used so as to protect
the syringe needle. At an opening of the second cap is formed with
a trench along a longitudinal direction of the cap. Two sides of
the trench are folded outwards to form the sliding pieces. Thereby,
after the syringe needle is used, it may be guided into the second
cap along the lateral directions of the sliding pieces. The trench
is gradually reduced along the opening of the second cap. Thereby,
the syringe needle can be guided into the cap by its lateral side
so as to avoid hurting the user.
[0005] Another object of the present invention is to provide a
simply and easily used safety syringe cap, wherein two outer folded
sliding pieces from two sides of the trench of the second cap are
extended horizontally as two wings.
[0006] A further object of the present invention is to provide
a simply and easily used safety syringe cap, wherein two inner lateral
sides of the trench of the second cap are extended with elastic
shielding pieces so that after the syringe needle is guided into
the trench, the shielding pieces have functions of opening and closing
as a door.
[0007] The various objects and advantages of the present invention
will be more readily understood from the following detailed description
when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] Referring to appended figures, the safety syringe cap of
the present invention is illustrated. The safety syringe cap includes
a first cap 10 a second cap 11 overlapping the first cap 10. The
first cap 10 is like a prior art syringe cap for sealing a syringe
before being used so as to protect the syringe needle 21. At the
opening 111 of the second cap 11 is formed with a gradual reduced
trench 112 along the longitudinal direction of the cap, two sides
of the trench 112 are folded outwards to form the sliding pieces
113 114. Thereby, after the syringe needle 21 is used, it may be
guided into the second cap 11 along the lateral directions of the
sliding pieces 113 114.
[0015] Referring to FIGS. 2 to 4 a pivotal portion is formed between
the syringe needle 21 and a cylinder 22. By the guiding of the sliding
pieces 113 114 the syringe needle 21 can slide into the trench
112 of the second cap 11 so as to be shielded therein. Then, it
is transferred for being further processed so as to control the
cost.
[0016] Referring to FIG. 5 in the present invention, two outer
folded sliding pieces 113 114 from two sides of the trench 112
of the second cap 11 can be extended horizontally as two wings 115
and 116 which have the functions of shielding and hindering, as
the embodiment illustrated in the drawing. Thereby, as the syringe
needle 21 is guided into the trench 112 it will not hurt the fingers
of the user.
[0017] Referring to FIG. 6 the two inner lateral sides of the
trench 112 of the second cap 11 are extended with elastic shielding
pieces 117 118 so that after the syringe needle 21 is guided into
the trench 112 the shielding pieces 117 118 have functions of
opening and closing like a door for preventing the syringe needle
21 from releasing along an opposite direction after the syringe
needle 21 is engaged with the cap 11.
[0018] Although the present invention has been described with reference
to the preferred embodiments, it will be understood that the invention
is not limited to the details described thereof. Various substitutions
and modifications have been suggested in the foregoing description,
and others will occur to those of ordinary skill in the art. Therefore,
all such substitutions and modifications are intended to be embraced
within the scope of the invention as defined in the appended claims. |
