Description
Technical field
The utility model relates to medical instruments fields, more particularly to disposable through conduit venous blood collection component.
Background technique
Disposable vein blood taking needle is for the Deep vein blood sampling by interposing catheter, one in clinical use
Side is interposing catheter connector, and the other side is pipe close puncture needle, is inserted into vacuum blood collection tube after venipuncture success, is made by negative pressure
With acquisition Deep vein blood preparation is used for clinical examination.Some diseases need to reach human body phase by interposing catheter in clinic
Answering the vein of histoorgan part, blood was collected, and acquisition Deep vein blood specimen carries out clinical examination come disease of clarifying a diagnosis, such as
Divide side Adrenal venous sampling, inferior petrosal sinus venous blood collection and renal vein segmentation blood sampling etc., is respectively used to primary hyperaldosteronism
The diagnosis of the classification diagnosis, cushing's syndrome of disease and the diagnosis of reninoma.
But currently without the venous blood collection component that can connect interposing catheter, after usually interposing catheter is inserted into position, blood is allowed
It is oozed from interposing catheter end, connects blood specimen with test tube, because human body Deep vein is very tiny, speed of bleeding is very slow, so that blood sampling
Time is long, and is easy to appear blood clotting obstruction conduit, and the staff for being responsible for connecing blood sample needs for a long time that holding test tube connects mark
This.In addition, test tube be not it is sterile, be easy to cause operating area or interposing catheter germ contamination, serious person to will lead to bacteremia
Or septicemia, cause serious consequence.Some operators are directly drawn blood with syringe, but vein pressure is low, the speed that blood extracts
It is very slow, cause blood that can not adopt if the negative pressure of blood drawing be easy to cause greatly very much sample dilutions or vascular wall to be adsorbed onto conduit mouth
Collection.
The disclosure of background above technology contents is only used for the design and technical solution that auxiliary understands the utility model, not
The prior art for necessarily belonging to present patent application shows above content in the applying date of present patent application in no tangible proof
In the case where having disclosed, above-mentioned background technique should not be taken to the novelty and creativeness of evaluation the application.
Utility model content
The utility model aim is to propose disposable through conduit venous blood collection component, avoids bacterium in blood collection procedure
Pollution, leakage vacuum or leakage blood, the generation of plugging phenomenon and medical staff will take test tube connect blood preparation for a long time.
For this purpose, the utility model proposes disposable through conduit venous blood collection component, specific technical solution is as follows.
It is disposable through conduit venous blood collection component, including blood resistance unit, pipe close puncture needle, pipe close puncture needle protective case,
Pipe close puncture needle needle stand, tube body, connection end and connector；Connection end is arranged in the tube body head end, is arranged on connection end
The tail end of connector, tube body is connected with pipe close puncture needle needle stand, and pipe close puncture needle needle stand is connected with pipe close puncture needle protective case, pipe
Plug puncture needle is connected with pipe close puncture needle protective case, and the outside of pipe close puncture needle is arranged in blood resistance unit；Wherein, the blood sampling group
Part head end is connect with interposing catheter, and blood collection assembly tail end is connect with vacuum blood collection tube.
Described is disposable through conduit venous blood collection component, and protrusion is arranged in the end of the interposing catheter, with connection
The screw thread matching of mouth setting is connected.
Described is disposable through conduit venous blood collection component, and the tube body is transparent pipe.
Described is disposable through conduit venous blood collection component, and the inner wall of the tube body uses at imitative technology of biological membrane
Reason.
The beneficial effect that the utility model is compared with the prior art includes:
(1) the utility model uses spiral duct connector, can be engaged with the protrusion of interposing catheter tight with blood collection assembly
It is close to be connected, it avoids leaking vacuum or leakage blood in blood collection procedure.
(2) tube body of the utility model is transparent pipe, can blood circumstance, inner pipe passway use in managing with clear view
Imitative technology of biological membrane processing, effectively avoids albumen and platelet adhesion reaction, avoids the generation of plugging phenomenon.
(3) blood collection assembly of the utility model is used for the intravenous blood collection in deep, and blood preparation is made to be in sterile vacuum
State, reduces the bacterium infection of conduit, also can reduce the operating pressure of medical worker, takes test tube to go to connect conduit without long-time hand
The blood preparation of end outflow.
