Abstract
The utility model discloses a multiple -cutting -edge face back of body cut needle tubing, including the needle tubing body, the needle tubing body is the needle point at its front end, the front of needle point has two flanks at least, and there are two flanks at the back, the rear end of needle tubing body be water graphic settings the cylinder pipe and with needle point integrated into one piece, the front of needle point increases the one or more flank for the positive needle point flank of needle tubing body increases with the horizontal plane intersection contained angle of cylinder pipe, and the transition of its both sides face is smooth and easy more naturally. It carry out venous transfusion, injection for clinical use person, the puncture is kept somewhere and draw blood etc. In the aspect of clinical treatment when using, can alleviate clinical use person's pain greatly. This kind of new product simple structure, convenient to use, safe and reliable, and low in production cost.
Description
Technical field
This utility model relates to a kind of medical apparatus being mainly used in the aspects such as venous transfusion, injection, puncture indwelling and blood drawing, particularly multiple-cutting-edge face back of the body cut type needle tubing.
Background technology
At present, because the medical needle tubing of common single use back of the body cut type uses healthy and convenient being widely applied.But, the medical needle tubing 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 tubing of this kind of common back of the body cut type is: such medical needle tubing front of common back of the body cut type only has a sword face, carry out the penetration Resistance that the aspects such as venous transfusion, injection, puncture indwelling and blood drawing produce to Clinical practice person and usually have two peak values, wherein, a penetration Resistance peak value appears on the needle point of needle tubing; Another penetration Resistance peak value then appears at the sword face 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 larger, carry out paracentesis to Clinical practice person more not smooth, the misery suffered by Clinical practice person is also larger.
Utility model content
The purpose of this utility model to provide a kind of multiple-cutting-edge face through comparatively effectively improvement back of the body cut type needle tubing, with overcome the medical needle tubing of existing common back of the body cut type also exist sword face because of needle tubing front crossing with cylindrical tube horizontal plane and formed flex point produce larger penetration Resistance and when carrying out to Clinical practice person that in venous transfusion, injection, puncture indwelling and blood drawing etc., clinical treatment apply, the drawback of increase Clinical practice person pain.
The purpose of this utility model is achieved in that this utility model multiple-cutting-edge face back of the body cut type needle tubing, comprise needle tubing body, described needle tubing body is needle point in its front end, the front of described needle point has two sword faces at least, there are two sword faces at the back side, the rear end of described needle tubing body is the cylindrical tube that arranges of horizontal plane and one-body molded with needle point, it is characterized in that: the front of described needle point increases one or more sword face, the horizontal plane intersection angle of the needle point sword face in needle tubing body front and cylindrical tube is increased, and the transition of its two sides is more naturally smooth and easy.
This utility model 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 according to the structural representation that the utility model proposes;
Fig. 2, be the structural representation of the medical needle tubing of original design common back of the body cut type before this utility model improvement.
Detailed description of the invention
Below in conjunction with drawings and Examples, structure of the present utility model is further described:
Reference numeral: 1, needle tubing body; A, needle point angle; β, angle; L, chamfer length.
In the drawings, this utility model multiple-cutting-edge face back of the body cut type needle tubing, comprise needle tubing body 1, described needle tubing body 1 is needle point in its front end, and the front of described needle point has two sword faces at least, and there are two sword faces at the back side, the rear end of described needle tubing body 1 is the cylindrical tube that arranges of horizontal plane and one-body molded with needle point, the front of described needle point increases one or more sword face, and the horizontal plane intersection angle β of the needle point sword face in needle tubing body 1 front and cylindrical tube is increased, and the transition of its two sides is more naturally smooth and easy.
This utility model is on the basis of the chamfer length L and needle point angle A that do not change original design needle point, the frontal slope of original design needle point increases one or more sword face, to cross the angle β that place formed with the horizontal plane in the needle point sword face and cylindrical tube that increase this utility model needle tubing body 1 front, thus make the transition between described needle point and cylindrical tube more naturally smooth and easy.
Like this, this utility model 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 utility model is correspondingly reduced, so the pain degree of the person that greatly can alleviate Clinical practice due to the increase of angle β described in the utility model.
Above-described is only preferred embodiments of the present utility model.It should be pointed out that to those skilled in the art, under the prerequisite not departing from this utility model principle, can also make some modification and improvement, this is also considered as belonging to protection domain of the present utility model.
