Description
Technical field
The utility model is related to one kind to adopt in medical diagnosis or blood sampling tool used in daily life, especially one kind
Blood pen, belongs to medical equipment technical field.
Background technology
With the continuous change of quality of life and living environment, the patient with diabetes is increasing, it is well known that
Diabetes patient needs the blood glucose level in often monitoring body fluid to manage the glucose amount taken in diet and need to inject
Insulin dosage, therefore, blood glucose meter and its matching used blood collecting pen, blood sugar test paper become necessity, and blood collecting pen is main
For taking a blood sample diabetic to complete the detection of blood glucose, clinical blood sampling is additionally operable to carry out routine inspection, commercially available blood sampling
Pen majority is the ejection mechanism using spring, applies ejection force to blood taking needle, and blood sampling, the wherein size of power are completed to puncture
Or the depth punctured is usually that adjusting blood collecting pen pen cover controls blood taking needle-pen sharp knife needle outlet with blood collecting pen nib distance
Distance, the connection of the two generally use helical structure, the size in the gap generated according to spiral adjust depth of needling, but for
Some are engaged in for the patient of manual labor throughout the year, and silkworm cocoon is will appear at finger causes superficial skin thicker, this spiral knot
The distance that structure is adjusted is limited, and puncture dynamics is inadequate, can not obtain compatible blood, results in the need for the pain that multi-pass operation increases patient
Sense.
Utility model content
The utility model technical issues that need to address are to provide the blood collecting pen knot that a kind of adjustable blood taking needle goes out needle length
Structure, it is rational to adjust the distance between blood taking needle and blood collecting pen pen cap, reach suitable puncture dynamics, avoids repeatedly puncturing increase
The feeling of pain of patient.
In order to solve the above technical problems, technical solution used by the utility model is：
A kind of blood collecting pen, including blood collecting pen shell, blood collecting pen shell one end are connect by a connector sleeve with blood collecting pen pen cap,
The syringe for installing blood taking needle is provided in blood collecting pen shell, the syringe is connected by scalable drive rod and blood collecting pen rear cover
Connect, be additionally provided on blood collecting pen shell connect with scalable drive rod by press button, it is characterised in that：The syringe includes interior needle
Cylinder and outer syringe, interior syringe are flush-mounted in outer syringe, and interior syringe can be moved axially relative to outer syringe, be also set up in interior syringe
It is useful for the support construction of support blood taking needle, support construction is and the integrally formed supporting block of inner cylinder；It is provided on interior syringe
External screw thread, outer syringe be equipped with the mutually matched internal thread of external screw thread, be provided with external screw thread on interior syringe, be arranged on interior syringe
Slip-resistant texture.
Technical solutions of the utility model further improvement lies in that：Connector sleeve is that dismountable buckle connects with blood collecting pen shell
It connects, the other end and the blood collecting pen pen cap of connector sleeve are to be threadedly coupled.
Technical solutions of the utility model further improvement lies in that：Several grooves are set on blood collecting pen pen cap.
Technical solutions of the utility model further improvement lies in that：Supporting block at least two.
By adopting the above-described technical solution, the technological progress that the utility model obtains is：
The utility model improves the syringe for installing blood taking needle, is interior syringe and outer syringe, interior needle by barrel design
Cylinder can be moved axially relative to outer syringe, to adjust the distance between blood taking needle and needle outlet on blood collecting pen pen cap, be convenient for labor
The high diabetes patient of fatigue resistance uses, and it is inadequate to avoid the occurrence of puncture dynamics, the defects of can not getting suitable blood.
Further, slip-resistant texture is set on interior syringe, syringe in diabetes patient's turn can be facilitated, nationality is to adjust out conjunction
Suitable goes out needle length.
