Abstract
The invention discloses a disposable medical needle point which comprises a needle point body. Two oblique planes are respectively formed on two sides of a first oblique plane of the front end of the needle point body by means of cutting, the needle point body is further provided with at least one cutting surface which is arranged on a needle point back surface of the first oblique plane, and the cutting surfaces are oblique planes. The disposable medical needle point has the advantages that suffering can be greatly relieved for clinical users when the disposable medical needle point is used for clinical medical application in the aspects of intravenous infusion, injection, puncture indwelling, blood drawing and the like for the clinical users; the disposable medical needle point which is a novel product is simple in structure, convenient to use and low in production cost and is safe and reliable.
Description
Technical field
The present invention relates to a kind of medical needle point of medical apparatus, particularly single use being mainly used in the aspects such as venous transfusion, injection, puncture indwelling and blood drawing.
Background technology
At present, because the medical needle point of common single use back of the body cut type uses healthy and convenient being widely applied.But, the medical needle point of existing this kind of common back of the body cut type structurally still also exists some defects, cause health care worker when carrying out clinical treatment application in venous transfusion, injection, puncture indwelling and blood drawing etc. to Clinical practice person, also can inevitably cause larger pain to Clinical practice person.Put into practice by a large amount of clinical treatment, find that the main structural deficiencies of the medical needle point of this kind of common back of the body cut type is: the medical needle point of such common back of the body cut type cuts out two inclined-planes respectively in the both sides on the first inclined-plane usually, but continue the part conical surface that maintain the first back side, inclined-plane projection.Like this, when the medical needle point of common back of the body cut type of structure like this is on the health of the person that is applied to Clinical practice, the needle point angle due to it is comparatively large and corresponding penetration Resistance is also comparatively large, the pain degree of the person that thus can increase Clinical practice.
Summary of the invention
The object of the invention is to provide a kind of medical needle point of single use through comparatively effectively improvement, with overcome the medical needle point of existing common back of the body cut type also exist the corresponding penetration Resistance because needle point angle is comparatively large also comparatively large and carry out the aspect clinical treatment application such as venous transfusion, injection, puncture indwelling and blood drawing to Clinical practice person time, thus the drawback of increase Clinical practice person pain.
The object of the present invention is achieved like this: the medical needle point of single use of the present invention, comprise needle point body, described needle point body cuts out two inclined-planes respectively in the first both sides, inclined-plane of its front end, it is characterized in that: described needle point body also at least offers a cutting face at its back side, the first inclined-plane.
Wherein, described cutting face is inclined-plane.
The present invention when carrying out in venous transfusion, injection, puncture indwelling and blood drawing etc. clinical treatment application to Clinical practice person, the pain degree of the person that greatly can alleviate Clinical practice.This new product structure is simple, easy to use, safe and reliable, and production cost is low.
Accompanying drawing explanation
Fig. 1, be the plan structure schematic diagram that the present invention improves the medical needle point of front common back of the body cut type;
Fig. 2, be the side structure schematic diagram that the present invention improves the medical needle point of front common back of the body cut type;
Fig. 3, be according to the present invention propose side structure schematic diagram;
Fig. 4, be according to the present invention propose plan structure schematic diagram.
Detailed description of the invention
Below in conjunction with drawings and Examples, structure of the present invention is further described:
Reference numeral: 1, needle point body; α, needle point angle; β, needle point angle; A, cutting face; K, the first inclined-plane.
In fig. 1 and 2, be the medical needle point of common back of the body cut type before the present invention's improvement.The medical needle point of this common back of the body cut type only cuts out two inclined-planes respectively in the both sides on the first inclined-plane, but continues the part conical surface that maintain the first back side, inclined-plane projection.
In figs. 3 and 4, the medical needle point of single use of the present invention, comprises needle point body 1, and described needle point body 1 cuts out two inclined-planes respectively in the first both sides, inclined-plane of its front end, described needle point body 1 also at least offers a cutting face A at its back side, the first inclined-plane, and described cutting face A is inclined-plane.
Obviously, through the medical needle point of single use of the present invention of improvement, its needle point angle and needle point angle β are far smaller than the needle point angle α of the medical needle point of common back of the body cut type.At least offer a cutting face A because the part conical surface of common back of the body cut type medical needle point back side projection is reamed a part by the present invention, and described cutting face A is inclined-plane.Like this, it is when carrying out clinical treatment application in venous transfusion, injection, puncture indwelling and blood drawing etc. to Clinical practice person, penetration Resistance of the present invention is correspondingly greatly reduced, so the pain degree of the person that greatly can alleviate Clinical practice because described needle point angle β reduces greatly.
Above-described is only preferred embodiments of the present invention.It should be pointed out that to those skilled in the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, this is also considered as belonging to protection scope of the present invention.
Claims (2)
1. the medical needle point of single use, comprise needle point body (1), described needle point body (1) cuts out two inclined-planes respectively in the first inclined-plane (K) both sides of its front end, it is characterized in that: described needle point body (1) also at least offers a cutting face (A) at its first inclined-plane (K) back side.
