Abstract
The utility model relates to a venous puncturing needle which is suitable for subcutaneous venous transfusion or blood pumping. The puncturing needle is in the shape of S, and is mainly composed of a cambered needle, the front section of a needle pipe, the bending section of the needle pipe and the back section of the needle pipe. The utility model has the advantages of convenient needle holding and paracentesis, high puncturing successful rate and relative safety of transfusion.
Description
This utility model relates to a kind of medical apparatus and instruments.Particularly a kind of a kind of S shape venipuncture needle that is used for venae subcutaneae transfusion or blood sampling.
Before the utility model proposes, venipuncture needle of the prior art is straight shape pin, and its needle point is on the extended line of needle tubing wall.In the use, puncture needle must become a tangible angle with vein, very easily wears out during undue force or penetrates the vein rear wall, leads to the failure.And experience person is arranged, and keep pin and vein opposing parallel during puncture as far as possible, to improve puncture success rate, it is little and inconvenient in fact to produce effects.In addition, even pin penetrates vein, because the elastic reaction of vein itself keeps vein reluctantly and the opposing parallel of pin, but needle point then is close on the lateral vein wall, so that the patient dare not continue inserting needle easily with stable puncture effect, deviate from vein or needle point bursting wall of vein so cause puncture needle in the infusion process easily, cause local hemorrhage or swelling.
It is convenient that the purpose of this utility model provides a kind of puncture, is difficult for wearing out the vein rear wall and infuses comparatively safe disposable a kind of S shape venipuncture needle.
Realize the purpose of this utility model be by following by way of: because puncture needle becomes S shape, can keep leading portion needle tubing and the certain parallel relation of venous under the needle-like attitude holding easily, add the needle point camber, penetrate vein after, be difficult for puncturing the vein rear wall.Transfusion or when getting the blood state, because leading portion needle tubing and back segment needle tubing are not at grade, so can keep the relative naturalness of leading portion needle tubing in duct of Arantius, arcual needle point also can be avoided wall of vein relatively, has improved safety.
The utlity model has and hold pin and puncture conveniently puncture success rate height, the advantage that infusion process is comparatively safe.
Below in conjunction with accompanying drawing this utility model is described in detail.
Fig. 1 is a sketch map of the present utility model.
Fig. 2 is the front view that this utility model needle point amplifies.
With reference to accompanying drawing.The radian of arc needle point 1 of the present utility model is to guarantee that the vertical height of needle point is no more than the needle tubing central point and is advisable.Needle tubing leading portion 2 is straight shape pipe with needle tubing back segment 4, and both length ratios generally are advisable with approximate 1:1.The flexibility of needle tubing bending section 3 does not get final product in the suitable degree in same plane to cause needle tubing leading portion 2 and needle tubing back segment 4.Backshank 5 is to be applicable to that transfusion has the shape of handle the time spent, also can make other shape according to purposes certainly, as does needle stand usefulness when being applicable to the blood drawing of socket syringe.The length of puncture needle and diameter can be with reference to the specifications of general entry needle and are decided.
During use, arc needle point 1 thrusts subcutaneous, penetrates vein again, and needle tubing leading portion 2 enters intravenous, and needle tubing back segment 4 stays in skin surface, so that fixing.
