Abstract
The invention discloses a kind of many blade surfaces backcut type needle tubing, including needle tubing body, described needle tubing body is needle point in its front end, the front of described needle point at least two blade surfaces, being backed with two blade surfaces, the rear end of described needle tubing body is the cylindrical tube and one-body molded with needle point that horizontal plane is arranged, and the front of described needle point increases one or more blade surfaces, the needle point blade surface in needle tubing body front is increased with the horizontal plane intersection angle of cylindrical tube, and the transition of its two sides is the most smooth and easy.It to Clinical practice person carry out venous transfusion, inject, puncture the aspect clinical treatment such as indwelling and blood drawing application time, the pain of the person that significantly can alleviate Clinical practice.This new product simple in construction, easy to use, safe and reliable, and production cost is low.
Description
Technical field
The present invention relates to a kind of be mainly used in venous transfusion, inject, puncture the medical apparatus of the aspect such as indwelling and blood drawing, particularly many blade surfaces backcut type needle tubing.
Background technology
At present, healthy and convenient being widely applied is used due to the common single use medical needle tubing of backcut type.But, the existing this kind of common medical needle tubing of backcut type structurally remains some defects, cause health care worker to Clinical practice person carry out venous transfusion, inject, puncture the aspect clinical treatment such as indwelling and blood drawing application time, also Clinical practice person can be inevitably resulted in bigger pain.Put into practice by a large amount of clinical treatments, the main structural deficiencies finding this kind of common medical needle tubing of backcut type is: such common backcut type medical needle tubing front only one of which blade surface, carry out venous transfusion to Clinical practice person, inject, puncture penetration Resistance produced by the aspect such as indwelling and blood drawing and generally have two peak values, wherein, a penetration Resistance peak value occurs on the needle point of needle tubing；Another penetration Resistance peak value then occurs in the blade surface in needle tubing front and the intersection of cylindrical tube horizontal plane, and the angle of this intersection is little, and the face of both sides is not nature transition and linkage and defines flex point, causes and the penetration Resistance peak value of this intersection is maximum.When penetration Resistance is the biggest, carrying out paracentesis to Clinical practice person the most not smooth, the misery suffered by Clinical practice person is the biggest.
Summary of the invention
The invention aims to provide a kind of many blade surfaces backcut type needle tubing through more effectively improvement, with overcome the existing common medical needle tubing of backcut type to also exist to be formed because the blade surface in needle tubing front intersects with cylindrical tube horizontal plane flex point to be produced bigger penetration Resistance and to Clinical practice person carry out venous transfusion, inject, puncture the aspect clinical treatment such as indwelling and blood drawing application time, increase the drawback of Clinical practice person's pain.
The object of the present invention is achieved like this: the present invention many blade surfaces backcut type needle tubing, including needle tubing body, described needle tubing body is needle point in its front end, the front of described needle point at least two blade surfaces, it is backed with two blade surfaces, the rear end of described needle tubing body is the cylindrical tube and one-body molded with needle point that horizontal plane is arranged, it is characterized in that: the front of described needle point increases one or more blade surfaces, the needle point blade surface in needle tubing body front is increased with the horizontal plane intersection angle of cylindrical tube, and the transition of its two sides is the most smooth and easy.
The present invention to Clinical practice person carry out venous transfusion, inject, puncture the aspect clinical treatment such as indwelling and blood drawing application time, the pain degree of the person that significantly can alleviate Clinical practice.This new product simple in construction, easy to use, safe and reliable, and production cost is low.
Accompanying drawing explanation
Fig. 1, be based on the present invention propose structural representation；
Fig. 2, it is the present invention structural representation of improveing the front original design common medical needle tubing of backcut type.
Detailed description of the invention
With embodiment, the structure of the present invention is further described below in conjunction with the accompanying drawings:
Reference: 1, needle tubing body；A, needle point angle；β, angle；L, chamfer length.
In the drawings, the present invention many blade surfaces backcut type needle tubing, including needle tubing body 1, described needle tubing body 1 is needle point in its front end, the front of described needle point at least two blade surfaces, is backed with two blade surfaces, the rear end of described needle tubing body 1 is the cylindrical tube and one-body molded with needle point that horizontal plane is arranged, the front of described needle point increases one or more blade surfaces so that the needle point blade surface in needle tubing body 1 front increases with the horizontal plane intersection angle β of cylindrical tube, and the transition of its two sides is the most smooth and easy.
The present invention is not on the basis of changing the chamfer length L and needle point angle A of original design needle point, the frontal slope of original design needle point increases one or more blade surface, cross the angle β that place formed, so that the transition between described needle point and cylindrical tube is the most smooth and easy increasing the needle point blade surface in needle tubing body 1 front of the present invention and the horizontal plane of cylindrical tube.
So, the present invention to Clinical practice person carry out venous transfusion, inject, puncture the aspect clinical treatment such as indwelling and blood drawing application time, the penetration Resistance of the present invention is correspondingly reduced due to the increase of angle β of the present invention, so the pain degree of the person that significantly can alleviate Clinical practice.
Above-described is only the 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, it is also possible to make some modification and improvement, this is also considered as belonging to protection scope of the present invention.
