Abstract
The utility model relates to a once-used sterile blood sampler, belonging to medical articles, and is suitable for blood sampling examinations in medical sanitary units. The utility model is provided with a cylindrical shell, a push rod is arranged in the shell, the head of the push rod is connected with a rubber plug, the middle part of the push rod is provided with a position step which is cooperated with the position hole which is arranged in the shell body, and the neck part of the push rod is provided with an easily folded concave groove which is connected with the end cover at the front end of the shell. The utility model can be used for replacing blood sampling by an injector and blood test with a glass test tube, has the advantages of simple operation, sanitation and cleanness, cross infection prevention, and low cost.
Description
This utility model relates to medical apparatus, is disposable use hemostix, is suitable for health service unit and uses in blood test.
People are when doing blood test, and the medical worker is general, and the syringes that use extract blood more, then blood are injected in the teat glass, test again.Above method needs syringe and teat glass, operates cumbersomely again, and causes that easily the cleaning of cross infection, particularly teat glass is very dirty, and infectious disease is easy to get.
The purpose of this utility model is a kind of disposable use sterile blood sampling device that not only can take a blood sample but also can make test tube of design.
Disposable use sterile blood sampling device of the present utility model, its solution is: have round stack shell, in an end cylinder of stack shell, ring-like spacing hole is arranged, the other end of stack shell is installed end cap, the stack shell outer wall is connected with the end cap outer shroud by screw thread, the inwall of stack shell seals mutually with the end cap internal ring, and the anterior outer wall of end cap is pyramid type, and injection needle can be installed.Push rod is installed in the stack shell, and one of push rod has push button, and there is limited step at the push rod middle part, and the limited step external diameter is greater than the ring-like spacing hole in the stack shell, to the position-limiting action that advanced of push rod.The other end head of push rod is circular cone, and the circular cone cervical region of ining succession has groove easy to break on the cervical region, and circular cone inserts in the plug, and the aperture of door on the plug matches with the push rod cervical region.Plug is that medical grade rubber is made, and is sealed and matched with stack shell, and is non-leakage when centrifugal in blood sampling and test tube.
Disposable use sterile blood sampling device of the present utility model, its stack shell, end cap and push rod are made by plastic material.

Below in conjunction with accompanying drawing 1-2 embodiment of the present utility model is elaborated.
This utility model is disposable use sterile blood sampling device, has round stack shell (5), in an end cylinder of stack shell (5), ring-like spacing hole (4) is arranged, screw thread (9) is arranged on the other end outer wall of stack shell (5), threaded outer wall is connected with end cap outer shroud (10), the stack shell inwall is sealed and matched mutually with end cap internal ring (11), the anterior injection needle of installing of end cap (12).Push rod (2) is installed in the stack shell, one end of push rod (2) has push button (1), there is limited step (3) at push rod (2) middle part, the other end head of push rod is circular cone (7), circular cone (7) inserts in the plug (8), push rod cervical region (13) matches with the plug aperture of door, has easily to analyse groove (6) on push rod cervical region (13).
Disposable use sterile blood sampling device of the present utility model, behind push rod (2) insertion stack shell (5), peace is gone into plug (8), and push rod circular cone (7) is inserted in the plug (8), screws on end cap (12) then, can use.When employing finishes, after push rod is moved plug (8) ring-like spacing hole (4) to and collided,, make the groove (6) of easily analysing on the push rod cervical region (13) produce and fracture with push rod (2) one foldings, remove end cap (12) simultaneously, become test tube, be used for blood test.This technology generation has been replaced blood collection needle and teat glass blood count, and is simple to operate, and sterile blood sampling abandons after the check, and sanitation and hygiene prevent cross infection.
Claims (2)
1, disposable use sterile blood sampling device, has round stack shell (5), push rod (2) is installed in the stack shell (5), the head that is circular cone (7) on push rod (2) connects plug (8), it is characterized in that ring-like spacing hole (4) is arranged in the stack shell (5), an end of stack shell (5) connects end cap (12), and there is limited step (3) at push rod (2) middle part, groove easy to break (6) is arranged on the push rod cervical region (13), and stack shell (5), push rod (2) and end cap (12) are made by plastic material.
2, disposable use sterile blood sampling device as claimed in claim 1 is characterized in that stack shell (5) and being connected of end cap (12) are that the screw thread (9) of stack shell outer wall links to each other with end cap outer shroud (10), and stack shell inwall and end cap internal ring (11) are sealed and matched.
