PUNCTURING DEVICE AND METHOD OF BLOOD SAMPLING Russian patent published in 2014 - IPC A61B5/151 A61B5/15 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to puncturing device or scarifier for blood sampling for medical analysis of blood drops, for instance, for measuring content of blood sugar. Puncturing device of scarifier for blood sampling with mobile holder for puncturing device, with rectilinear guide for guiding mobile holder, with mobile holder drive and with trigger device for triggering puncturing movement of puncturing device, in which after manual start of trigger device mobile holder can perform translational motion under impact of drive. Drive contains curved guide unit, which has infinite curved path, into direct gear with which mobile holder is brought. Holder is turned around its rotation axis, which is located outside curved path in such a way that infinite curved path performed rotation around rotation axis. Mobile holder is made with possibility of translational travel. Method of blood sampling in accordance with which puncturing device is moved forward and then immediately moved back. Puncturing device is made with possibility of instant introduction into patient's body with at least its tip and performs translational movement in mobile holder, brought into motion by spring drive. Mobile holder is directed directly on infinite curved path of curved guide unit and inside said path and turned around rotation axis, which is located outside infinite curved path in such a way, that infinite curved path performs rotation around rotation axis. Mobile holder is made with possibility of translational travel.

EFFECT: invention has more reliable and fast-acting construction of blood sampling device in part of movement on guide inside curved infinite path.
