Description

The adjustable blood collecting pen of a kind of depth of needling

Technical field

This utility model relates to the blood sampling medical apparatus and instruments of blood count in a kind of medical diagnosis, the adjustable blood collecting pen of especially a kind of depth of needling.

Background technology

Blood collecting pen is widely used in medical diagnosis and individual blood sugar test.Operational approach is aperture of thorn on tester's finger tripe, makes blood ooze a little, detects with the blood sugar test paper draw blood then.Common blood collecting pen structure is at present: the front end of pen container has the cap for brush, in pen container, be movably installed with piston ejector ram, ejector piston, be provided with the contact pin cover of disposable pricker at the piston ejector ram, ejector piston front end, be provided with elastic lock in the piston ejector ram, ejector piston side, in the piston ejector ram, ejector piston rear end emission spring is installed, be provided with latch hook with snap fit at the pen container inwall, the firing button of stirring elastic lock is installed on the pen container sidewall.When piston ejector ram, ejector piston was pushed rearward, elastic lock was blocked (launch spring and be compressed this moment) by latch hook, push firing button, and piston ejector ram, ejector piston is pushing away pricker and stretching out a bit of distance fast, thrusts skin, in the pen container of withdrawing then, finishes acupuncture manipulation.This blood collecting pen is suitable for for adult's finger skin, but to child's finger skin, just seems that acupuncture is dark excessively because skin is thin, and pain is arranged, and for the skin of physical labourer, owing to there is callus just to seem that acupuncture is shallow excessively, can't adopt blood.

Summary of the invention

This utility model provides a kind of adjustable blood collecting pen of depth of needling of suitable different skin thickness for solving the technical problem that exists in the known technology.

The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:

The adjustable blood collecting pen of a kind of depth of needling, comprise the pen container and the cap for brush, be movably arranged on the piston ejector ram, ejector piston in the pen container, be arranged on the contact pin cover of piston ejector ram, ejector piston front end, be arranged on the lateral elastic lock of piston ejector ram, ejector piston, be installed in the emission spring of piston ejector ram, ejector piston rear end, be arranged on the latch hook that cooperates with elastic lock of pen container inwall, and be installed in the firing button of stirring elastic lock on the pen container sidewall, the described cap for brush is tubular, the uniform internal tooth that is shaped on of cap for brush front inner wall, the movable adjustable cap that has pin hole of installing of cap for brush front end, the inner port of adjustable cap is the Horse hoof angle, be shaped on the elastic lock that is connected with the cap for brush on the sidewall of adjustable cap, be shaped on the protruding sphere in the location that cooperates with cap for brush internal tooth on the elastic lock, be shaped on the bumping post of regulating by the Horse hoof angle on the piston ejector ram, ejector piston.

This utility model can also adopt following technical scheme:

Described pen container rear end is equipped with button pull bar and spring, and the pull bar front end is shaped on L shaped notch, and the rear end of piston ejector ram, ejector piston is provided with the pin with L shaped notch coupling.

The elasticity withdraw of the needle button that has push rod is installed in described pen container side, and contact pin cover side correspondence is shaped on the gap of coupling.

Described cap for brush outer round surface circumferentially is shaped on scale mark, and correspondence is shaped on the arrow labelling on the adjustable cap.

Advantage and the good effect that the utlity model has are:

Because in the movable installation of cap for brush front end inner port is Horse hoof angle adjustable cap, be shaped on the bumping post of regulating by the Horse hoof angle on the piston ejector ram, ejector piston, by rotating the corner of adjustable cap, reach and adjust the length that pricker stretches out, solved the needle stick problems of different skin thickness, in the pen container rear end button pull bar is installed in addition, it is more convenient to make piston ejector ram, ejector piston fall back on transmitting site, and this utility model also has advantage simple in structure, that be easy to make in addition.
