Technical field
The present invention relates to a kind of medical apparatus and instruments, specifically a kind of safety type blood collecting protecting sleeve.
Background technology
We know, blood collection, utilization are important curative activities, blood taking needle, the blood taking tube important apparatus that is absolutely necessary.Past generally uses is traditional syringe blood drawing, transfers to blood taking tube again and operation such as inspects by ready samples; In recent years, the vacuum tube single step is directly taken a blood sample becomes advanced blood sampling means.The vacuum tube single step is directly taken a blood sample and is adopted double end blood taking needle, vacuum test tube, blood collecting protecting sleeve hemostixes such as (needle holders).Existing blood collecting protecting sleeve (needle holder) mainly comprises the blood taking tube sleeve of blood taking needle Connection Block and hollow, and the blood taking needle Connection Block is positioned at barrel forward end, and with the sleeve integrative-structure, sleeve rear end has an opening for the usefulness of accepting blood taking tube.After the double end blood taking needle installed and fixed, an end was positioned at the front end of needle holder, was used for puncture, and the other end is arranged in the sleeve of needle holder, was used for being connected cooperation with vacuum test tube and took a blood sample.After blood sampling finished, must both hands operating simultaneously could be with the separating of needle holder and double end blood taking needle, and blood taking needle is disposed, troublesome poeration, complexity, and also there is very big unsafe factor in exposed syringe needle.And if do not separate needle holder and blood taking needle, two external members are handled simultaneously, and needle holder is also the same with blood taking needle can only disposablely to be used, and have so just improved the blood sampling cost greatly.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of structure reasonable, and the blood taking needle loading and unloading are easy to use, and it is simple to operate to take a blood sample, and avoids being caused cross infection, the safety type blood collecting protecting sleeve that safety is good by accidental needle sticks.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of safety type blood collecting protecting sleeve, it comprises overcoat, the blood taking needle Connection Block, spring, inner sleeve, the overcoat rear end opening, it is characterized in that: the overcoat front end is provided with a central through hole, overcoat front end inboard is provided with several elastic card claws, blood taking needle Connection Block rear portion is provided with annular boss, the front portion is with spring, it is fixed in the overcoat central through hole by elastic card claw in overcoat, the inner sleeve tight fit is installed in the overcoat, its front end is uncovered, back-end closure, and the uncovered end face of inner sleeve is provided with the inclined-plane that cooperates with elastic card claw.
The said elastic card claw of the present invention rear portion is provided with the fixedly claw hook of blood taking needle Connection Block, and the claw hook rear end face is the inclined-plane that tilts laterally, also is provided with the step that cooperates with claw hook on the blood taking needle Connection Block annular boss.
The said central through hole inwall of the present invention is axially arranged with some strip bulges, is axially arranged with some strip grooves on the anterior outer wall of blood taking needle Connection Block, and slip is packed in the overcoat central through hole.
Be axially arranged with the raised line of installing with the overcoat tight fit on the outer wall of the said inner sleeve of the present invention rear end.
The said internal diameter that is enclosed within the diameter of the spring on the blood taking needle Connection Block greater than the overcoat central through hole of the present invention.
The present invention's blood taking needle Connection Block in overcoat is movably arranged in the overcoat front end central through hole by elastic card claw, the double end blood taking needle is installed on the blood taking needle Connection Block by the external screw thread on it, one of blood taking needle is positioned at the overcoat front end, be used for puncture, the other end blood taking needle is arranged in overcoat, be used for during use being connected, take a blood sample with vacuum test tube.After blood sampling finishes, take vacuum test tube away, inner sleeve is pushed in the overcoat, inner sleeve and overcoat are tightly fixed.The inclined-plane of the uncovered end face of inner sleeve front end cooperates with the inclined-plane that elastic card claw tilts laterally, struts elastic card claw, makes the qualification of its releasing to the blood taking needle Connection Block, and the blood taking needle Connection Block springs in the inner sleeve together with the double end blood taking needle under the effect of spring.Against existing technologies, the present invention constructs rationally, the assembling of blood taking needle and vacuum test tube, easy to use, it is simple to operate to take a blood sample, and after having taken a blood sample, inner sleeve is pushed in the overcoat, can automatically blood taking needle Connection Block and blood taking needle be recovered in inner sleeve and the overcoat, avoid syringe needle to expose, accidental puncture causes cross infection, and safety is good.
