Abstract
The invention discloses a novel blood taking needle. The novel blood taking needle comprises a needle rod and a needle head arranged on the top of the needle rod. The point end of the needle head is an oval plane, and heparin coatings are arranged on the outer wall of the needle rod and the outer wall of the needle head. The top of the needle head is of a transverse oval structure which is identical with the transverse vein structure of fingerprints, and therefore pain of the human body in the blood taking process can be reduced. The needle head is widened in the transverse direction, and therefore the amount of bleeding is large in the blood taking process, and the healing speed of wounds is not influenced. The heparin coatings are arranged on the outer wall of the blood taking needle, and therefore the influence on the blood glucose result from the blood clotting response is reduced, and the measuring result is accurate.
Description
Technical field
The present invention relates to a kind of armarium accessory, particularly relate to a kind of blood taking needle.
Background technology
At present, in medical and health industry, the needle tip of the blood taking needle used during blood sampling is all circular, easily cause user's pain in blood collection procedure, and be subject to the restriction in syringe needle cross section, amount of bleeding has not enough phenomenon, continue the blood sampling meeting user is caused to sense of discomfort, and general blood taking needle mostly is simple stainless steel structure, easily cause the blood coagulation reaction, cause measurement result deviation to occur.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Novel blood taking needle, can when blood sampling, reduce the human body pain sense, and increase amount of bleeding, and can reduce the impact of blood coagulation reaction on blood glucose test result.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of Novel blood taking needle is provided, comprises: shank and the syringe needle that is positioned at the shank top, the tip of described syringe needle is elliptic plane, and the outer wall of described shank and described syringe needle is provided with heparin coating.
In a preferred embodiment of the present invention, the top of described syringe needle is oval, and transverse diameter is 0.5 ~ 1.5mm, and vertical footpath is 0.3 ~ 1mm.
In a preferred embodiment of the present invention, the cross section of described shank is circular or oval.
In a preferred embodiment of the present invention, the described shank of described Novel blood taking needle and described syringe needle are that stainless steel material is made.
The invention has the beneficial effects as follows: Novel blood taking needle of the present invention, comprise shank and the syringe needle that is positioned at the shank top, the top of described syringe needle is oval, and the outer wall of described shank and described syringe needle is provided with heparin coating, horizontal ellipsoidal structure design is taked at the top of syringe needle, consistent with the horizontal vein structure of fingerprint, can in blood collection procedure, reduce the human body pain sense, and the syringe needle of blood taking needle laterally broadens, amount of bleeding while making to take a blood sample is more, and do not affect the healing rate of wound, the outer wall of described shank and described syringe needle is provided with heparin coating, can reduce the impact of blood coagulation reaction on blood sugar effects, make measurement result more accurate.
The accompanying drawing explanation
Fig. 1 is the structural representation of Novel blood taking needle one preferred embodiment of the present invention;
Fig. 2 is the schematic cross-section of the needle tip of Novel blood taking needle shown in Fig. 1;
Fig. 3 is that in another preferred embodiment of Novel blood taking needle of the present invention, the shank cross section is circular right view;
Fig. 4 be Novel blood taking needle of the present invention again in a preferred embodiment shank cross section be oval-shaped right view;
In accompanying drawing, the labelling of each parts is as follows: 1, syringe needle, 2, shank, 3, heparin coating.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to accompanying drawing, the embodiment of the present invention comprises:
A kind of Novel blood taking needle, comprise shank 2 and the syringe needle 1 that is positioned at shank 2 tops, and the top of syringe needle 1 is oval, and transverse diameter is 0.5 ~ 1.5mm, and vertical footpath is 0.3 ~ 1mm.And shank 2 is provided with heparin coating 3 with the outer wall of syringe needle 1.The top of syringe needle 1 is oval, and the cross section of shank 2 can be circular or oval.This Novel blood taking needle is that stainless steel material is made.
When Fig. 3 means that shank 2 is circular cross-section, needle tip is oval-shaped schematic diagram; When Fig. 4 means that shank 2 is elliptic cross-section, needle tip is oval-shaped schematic diagram, and the oval transverse diameter of shank 2 and needle tip, vertical footpath direction are consistent.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
Claims (4)
1. a Novel blood taking needle, is characterized in that, comprising: shank and the syringe needle that is positioned at the shank top, the tip of described syringe needle is elliptic plane, and the outer wall of described shank and described syringe needle is provided with heparin coating.
