Abstract
The present invention generally relates to an automatic lancing device for withdrawing a blood sample, comprising a pushing member positioned at a back end of a body and a rotatable cap combined with a front end of the body for regulating the combination length of the body and the ejection length of a lancet, thereby obtaining a blood sample exactly at a desired position without misoperation and adjusting the penetration length of lancet according to depth of the skin.
Claims4
An automatic lancing device for withdrawing a blood sample, comprising:
- a hollow cylindrical body;
- an operation mechanism having a lancet exchangeably fitted at the front of a lancet holder positioned inside the body, and an impact-receiving member combined with the other side of the lancet holder and receiving impact to eject the lancet from the body;
- an impact-generating mechanism having an impact-transmitting member positioned at a back end of the operation mechanism and transmitting impact to the impact-receiving member;
- and
- a length-regulating mechanism comprising a length-regulating member rotationably combined with the outer circumference of a front case enclosing the lancet at the front end of the body and regulating a ejection length of the lancet from the front case.
