Abstract
The utility model discloses a combined blood taking needle. The combined blood taking needle comprises a needle tip, an injector and a blood guide tube. The needle tip is connected with the injector and the blood guide tube respectively, the tail end of the blood guide tube is connected with a puncture head, and a sealed cover is sleeved on the outside of the puncture head. According to the combined blood taking needle, the needle tip is connected with both the injector and the blood guide tube, so that blood for blood gas analysis is drawn through the injector, blood required by other test items can be drawn continuously through the blood guide tube, drawing of blood for different test items is not affected mutually, blood required by all test items can be all drawn out through a puncture, puncturing hurts to patients can be reduced, and the work efficiency of workers can be improved.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of blood taking needle.
Background technology
At present, clinically to patient's blood drawing, because inspection item is more, as blood gas analysis, routine blood test, liver function, kidney merits etc., often can take out a lot of pipes while therefore drawing blood; Need to adopt blood gas analysis needle to extract for the required blood of blood gas analysis, for required blood of detection such as routine blood test, liver function, kidney merits, generally adopt vacuum blood taking needle to draw blood.
Because blood gas analysis needle and the anticoagulant in each vacuum test tube of the different test item desired bloods of storage are different, therefore after extracting the blood gas analysis desired blood, for avoiding blood contamination, generally need to again puncture, to extract other test item desired blood, once add patient's misery and again puncture, also once added the workload of clinical nurse.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of combination type blood taking needle, and it just can extract the required blood of test item such as comprising blood gas analysis out by one-time puncture, and the blood drawing puncture time is few, can reduce patient's misery.
This utility model combination type blood taking needle, comprise syringe needle, syringe and emissary vein, and described syringe needle is connected with emissary vein with syringe respectively, and described emissary vein end is connected with puncturing head, and described puncturing head overcoat has sealing shroud.
Further, between described syringe needle and syringe, employing is hose connection.
Further, be provided with tongs on described flexible pipe.
Further, be provided with needle handle on described syringe needle.
The beneficial effects of the utility model: this utility model combination type blood taking needle, because its syringe needle has connected syringe and emissary vein simultaneously, therefore extract the blood of blood gas analysis by syringe, can continue to extract the required blood of other test item by emissary vein, and the blood that extracts different test items is independent of each other, one-time puncture can all be extracted out by the blood that all test items are required, can reduce patient's puncture injury, can improve staff's work efficiency simultaneously.
Description of drawings
The structural representation of Fig. 1 this utility model combination type blood taking needle.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is further described.
As shown in the figure, the present embodiment combination type blood taking needle, comprise syringe needle 1, syringe 2 and emissary vein 3, and described syringe needle 1 is connected and is connected with emissary vein with syringe 2 respectively, and described emissary vein 3 ends are connected with puncturing head 4, and described puncturing head 4 overcoats have sealing shroud 5.
During use, need to fill the required anticoagulant of blood gas analysis blood in syringe 2, after by syringe 2, extracting the required blood of blood gas analysis, pull out sealing shroud 5, puncturing head 4 is connected with vacuum test tube, utilize the negative pressure of vacuum test tube, can the required blood of other test item will be extracted, like this to patient carry out one-time puncture can will comprise the blood of blood gas analysis and other test item all extract out, puncture time is few, patient's misery can be reduced, blood sampling staff work efficiency can be improved simultaneously.When taking out the blood of blood gas analysis, because sealing shroud 5 seals up puncturing head 4, therefore only having a small amount of blood enters into emissary vein 3; And when taking out other and detect required blood, due to blood in human body in, press greater than blood pressure in syringe 2, the blood in syringe 2 can water conservancy diversion yet.
As the improvement to this enforcement, adopt flexible pipe 6 to connect between described syringe needle 1 and syringe 2, can make like this manufacturing of blood taking needle simpler, certainly in different embodiments, described syringe needle 1 also can directly be connected with syringe 2.
As the improvement to this enforcement, be provided with tongs 7 on described flexible pipe 6, after syringe 2 is completed blood draw, by tongs 7, clamp flexible pipe 6, can prevent blood water conservancy diversion in syringe 2, the blood drawing safety is better.
As the improvement to this enforcement, be provided with needle handle 8 on described syringe needle 1, can make puncture procedure more convenient by needle handle 8.
Explanation is finally, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, this utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
