Description
Technical field
This utility model belongs to hypodynia trace blood technical field, relates to a kind of blood sampling instrument that uses in medical diagnosis and individual blood testing, is specifically related to a kind of resetting means of blood collecting pen.
Background technology
Blood collecting pen is used to cooperate disposable blood taking needle to gather tip blood, comprises blood collecting pen or hemostix as blood sugar test device assemblies such as system for detecting blood sugar, blood glucose monitoring system, blood-sugar detecting instruments.This blood sampling apparatus is in order to reduce patient's misery, avoids many people of syringe needle to intersect using contacting of infection and medical personnel and syringe needle.When blood collecting pen uses, make its written first conflict human body skin, control assembly such as button by blood collecting pen touches then, order about inner blood taking needle generation rapid movement and go out the blood sampling nib, blood taking needle elasticity bounces back after reaching the limit again, on human body skin, form minimum acupuncture wound thus, so that the usefulness of blood sampling detection.
Some blood collecting pens have been developed in the prior art, blood collecting pen commonly used comprises the blood sampling nib, puts needle stand, pull handle, put blood taking needle is set in the needle stand, put the fixedly connected guide post in needle stand rear end, the spacing pedestal of the spacing guide post of the terminal arranged outside of described guide post, described spacing pedestal and pull handle adhere to by viscose glue.When blood collecting pen uses, putting needle stand internal fixation blood taking needle earlier, remove the over cap of blood taking needle upper end, install the blood sampling nib then and prepare to take a blood sample.
During blood sampling, first cleaning-sterilizing blood sampling site; The pull handle of blood collecting pen is pulled back, move after driving the spacing pedestal that clings with pull handle, owing to move after moving the pulling guide post behind the spacing pedestal, with guide post fixed put to move behind the needle stand make the elastic clip of putting the needle stand outside and the portion of controlling outside putting needle stand control button to cooperate spacingly, finish resetting of blood taking needle.Blood sampling site skin presses the blood sampling nib of blood collecting pen, and the button of controlling of pressing the portion of controlling discharges the compression spring that is positioned at the elastic clip rear end, blood taking needle is launched out take a blood sample.Back-moving spring is set controlling between portion rear end and spacing pedestal, can makes the blood taking needle resilience.
Yet owing to adopting viscose glue to adhere between spacing pedestal in the prior art and pull handle, viscose glue comes off easily and makes blood collecting pen can not carry out reset operation after use a period of time, has significantly reduced the service life of blood collecting pen like this.And the fixing of spacing pedestal and pull handle adheres to by viscose glue, and what, the position and the adherent time that apply that apply viscose glue during the manufacturing all can exert an influence to finished product, cause the quality of producing the back cost stable inadequately.The present invention comes therefrom.
