Description
The present invention relates to a spring for a lancet device, and more particularly to a spring for a lancet device which is coupled to a slider through which the lancet needle is inserted and which provides an elastic force to the slider.
In general, lancet devices are used in medical facilities to stab the patient's skin and obtain blood samples from the patient. The lancet device is used when only a small amount of blood is needed. When you get a blood sample, it usually stings your finger or other appropriate area of your body with a needle. Given the blood-borne disease, it is important that after the use of the lancet, no one else comes into contact with the lancet. Thus, one side of the lancet device should be designed so that the lancet needle does not accidentally scratch the other person after stabbing the patient's skin.
Reflecting the above, Patent Publication No. 10-2012-0038457 (lancet device in which the lance retracts) comprises a hollow housing forming a cavity and having a proximal end and a distal end; A slider at least partially slidable from an outer position to a pushed position along a longitudinal axis within a cavity of the hollow housing; A needle holder that holds the needle and is translationally movable along its longitudinal axis when rotated from its initial position to its advanced position about the longitudinal axis; A first biasing member disposed within the hollow housing at the distal end and having a biasing force applied to the needle holder toward the proximal end as the slider moves to the pushed position; Wherein the slider is in an outward position when the needle holder is in the initial position and the needle holder is in the forward position when the needle holder is in its initial position, The needle holder extends beyond the proximal end of the hollow housing to the outside of the cavity and when the slider slides from the outer position to the pushed position the needle holder is moved to the advanced position.
In addition, Japanese Laid-Open Patent Application No. 10-2011-0017063 (lancet block and lancet actuator) has a lancet having a needle formed at the bottom of a bar-shaped body and a cam protrusion of a predetermined length formed at a side of the body; The lower part of the upper part and the lower part of the lancet corresponding to the cam protrusion are made of a material which ruptures when the lancet is moved in a relatively downward direction, And a lancet case formed of a thin film of material elastically expanding and contracting, the lower portion being formed of a thin film which is easily ruptured by the needle.
According to the above-mentioned patents, the internal configuration of the lancet device is complicated by using a spring of a general coil type in order to prevent the lancet needle from being exposed to the outside after the lancet needle is fired forward and pierced the skin of the patient, And the assembling is not simple. Therefore, it is difficult to use as a disposable lancet device.
The lancet needle is fired through the shape change of the spring without additional configuration in the lancet device, and the lancet needle is pushed into the lancet device and then exposed back to the outside of the lancet device. And to provide a spring for a lancet device.
In order to accomplish the above object, the present invention provides a spring for a lancet device which is provided inside a main body of a lancet device and moves a lancet needle tip by an elastic action, And an elastic part wound in a coil spring shape; And a needle holder which is extended from the other end of the elastic part and arranged in the longitudinal direction of the elastic part on the side of the elastic part and is slidably coupled inward from the front of the main body, When the latch is released, the needle holder is fired forward due to the elastic action of the elastic part, and the lancet needle is pushed on the patient's skin and then hooked on the slider slidably coupled to the inside so as to come into the inside of the body again so that the elastic part moves forward So as to fix it.
The fixing part may be disposed parallel to the elastic part on the side of the elastic part, and may be formed to a size corresponding to ½ of the length of the elastic part.
The fixing portion may include a first extending portion extending in a tangential direction at the other end of the elastic portion;
A second extension portion bent at the first extension portion and extending a certain length in the direction of one end of the elastic portion; And a third extension portion which is bent in the elastic portion direction or the opposite direction in the second extension portion and hooked on the slider slidingly coupled inward.
The angle formed by the first extending portion and the second extending portion and the angle between the second extending portion and the third extending portion may be 90 占 3 3 占.
According to the present invention having the above-described configuration, the following effects can be achieved.
First, the present invention can prevent the spring from moving back and forth by fixing the position of the spring using the slider after the lancet needle is fired and piercing the patient's skin, and it is possible to retract the lancet needle back to the inside of the main body, It is possible to prevent accidents.
Further, when the spring according to the present invention is used, the configuration inside the lancet device is simplified, the assembly is simple, and the manufacturing cost is low.
