ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a lancet having a blood-collecting needle with a safety feature. In particular, the present invention relates to a lancet having a blood-collecting needle with a safety feature, which can prevent blood-mediated infections of AIDS, hepatitis, or other pathogenic bacteria due to careless impalement of a person collecting blood or handling waste disposition thereafter. This is accomplished by means of disposing a cap with a blood-collecting needle by repositioning the point end of the needle inside the cap via a return spring after collecting blood therein.
BACKGROUND OF THE INVENTION
A conventional lancet has a needle
9
, as illustrated in
FIG. 1
, inserted into the center of a body
6
, the frontal part
9
of which is connected to a detachment cap
7
which temporarily protects the terminal part of the needle
9
. In using a blood-collecting needle
5
, the detachment cap
7
is separated therefrom to expose the needle
9
. While collecting blood, the needle
9
is set up inside the cap
3
of a cylinder
1
which is used as a gun (as shown in FIG.
2
). However, in separating the blood-collecting needle
5
from the gun after collecting blood, the needle
9
becomes exposed, which may pose a risk to a person collecting blood, who can be infected with AIDS, hepatitis or other pathogenic bacteria by means of an accidental prick of the needle
9
. Moreover, the blood-collecting needle
5
is not only small in size, but also the exposure thereof after use cannot be easily identified by the naked eye. Consequently, a person handling waste disposition after blood collection is also at risk of becoming infected with AIDS, hepatitis or other pathogenic bacteria by an accidental prick of the needle
9
. In the Figures, those parts not explained in detail, or the parts
2
,
4
and
8
as illustrated are a button, a clip, and a detachment part, respectively.
SUMMARY OF THE INVENTION
The present invention was designed to solve the aforementioned problems, with the objective of providing a lancet having a blood-collecting needle with a safety feature. In particular, the present invention relates to a lancet having a blood-collecting needle with a safety feature, which can prevent blood-mediated infections of AIDS, hepatitis, or other pathogenic bacteria due to careless impalement of persons collecting blood or handling waste disposition thereafter, by means of disposing a cap with the blood-collecting needle by repositioning the point end of the needle inside the cap via a return spring.
In order to achieve the aforementioned objectives, the present invention provides a lancet having a safety feature on a blood-collecting needle, which comprises as follows: a cap of a barrel body, having its lower part narrower than the upper part, assembled as such with two sections; a screw thread corresponding to said cap connecting screw on the inner circumference of the upper part of the cap; a stop projection protruding from the lower part thereof; a stroke stop projection at the inner surface of the lower part of the cap, from a certain distance from said stop projection; a needle stop projection at the slot; a plate-like elastic return spring at the inside base of the cap; a stop ring at the upper part of the body in which a needle is installed; a connecting rod at the upper part of the blood-collecting needle, attaching or detaching from the connecting encasement; a square fixed ring at the lower part thereof; a body fixed screw, at the lower part thereof, corresponding to said needle stop projection; and a detachment knob at the lower part of the blood-collecting needle.
