Abstract

The utility model discloses the medical needle point of a kind of disposable use, comprise needle point body, described needle point body is cut out respectively two inclined-planes in the first both sides, inclined-plane of its front end, and described needle point body is also at least offered a cutting face at its first beveled point back side, and described cutting face is inclined-plane.It can greatly alleviate the pain of clinical user when carrying out the clinical treatment application of the aspect such as venous transfusion, injection, puncture indwelling and blood drawing to clinical user.This new product is simple in structure, easy to use, safe and reliable, and production cost is low.

Description

The medical needle point of disposable use

Technical field

This utility model relates to a kind of medical apparatus, the particularly medical needle point of disposable use that is 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 disposable use back of the body cut type is used healthy and convenient being widely applied.Yet, the medical needle point of the common back of the body cut type of existing this class structurally still exists some defects, cause health care worker when carrying out the clinical treatment application of the aspect such as venous transfusion, injection, puncture indwelling and blood drawing to clinical user, also can inevitably cause larger pain to clinical user.By a large amount of clinical treatments, put into practice, the primary structure defect of finding the medical needle point of the common back of the body cut type of this class is: the medical needle point of such common back of the body cut type is cut out respectively two inclined-planes in the both sides on the first inclined-plane conventionally, but continues retaining the part conical surface of the first back side, inclined-plane projection.Like this, when so the medical needle point of common back of the body cut type of structure is on being applied to the health of clinical user, because its needle point angle is compared with large and corresponding penetration Resistance is also larger, thereby can increase the pain degree of clinical user.

Utility model content

The purpose of this utility model is that a kind of medical needle point of disposable use through comparatively effectively improveing will be provided, with overcome the medical needle point of existing common back of the body cut type exist because of needle point angle compared with large corresponding penetration Resistance also when carrying out greatly the aspect clinical treatments such as venous transfusion, injection, puncture indwelling and blood drawing to clinical user and apply, thereby increase the drawback of clinical user pain.

The purpose of this utility model is achieved in that the medical needle point of the disposable use of this utility model, comprise needle point body, described needle point body is cut out respectively two inclined-planes in the first both sides, inclined-plane of its front end, it is characterized in that: described needle point body is also at least offered a cutting face at its back side, the first inclined-plane.

Wherein, described cutting face is inclined-plane.

This utility model, when carrying out the clinical treatment application of the aspect such as venous transfusion, injection, puncture indwelling and blood drawing to clinical user, can alleviate the pain degree of clinical user greatly.This new product is simple in structure, easy to use, safe and reliable, and production cost is low.

Accompanying drawing explanation

Fig. 1, be the plan structure schematic diagram of the medical needle point of common back of the body cut type before this utility model improvement;

Fig. 2, be the side structure schematic diagram of the medical needle point of common back of the body cut type before this utility model improvement;

Fig. 3, be according to the side structure schematic diagram that the utility model proposes;

Fig. 4, be according to the plan structure schematic diagram that the utility model proposes.

The specific embodiment

Below in conjunction with drawings and Examples, structure of the present utility model is further described:

Reference numeral: 1, needle point body; A, needle point angle; B, needle point angle; A, cutting face; K, the first inclined-plane.

In Fig. 1 and Fig. 2, it is the medical needle point of common back of the body cut type before this utility model improvement.The medical needle point of this common back of the body cut type is only cut out respectively two inclined-planes in the both sides on the first inclined-plane, but continues retaining the part conical surface of the first back side, inclined-plane projection.

In Fig. 3 and Fig. 4, the medical needle point of the disposable use of this utility model, comprises needle point body 1, and described needle point body 1 is cut out respectively two inclined-planes in the first both sides, inclined-plane of its front end, described needle point body 1 is also at least offered 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 the disposable use of this utility model of improvement, its needle point angle is the needle point angle a that needle point angle b is far smaller than the medical needle point of common back of the body cut type.Because this utility model reams the part conical surface of the medical needle point of the common back of the body cut type back side projection part and at least offers a cutting face A, and described cutting face A is inclined-plane, thereby makes described needle point angle b less than the needle point angle a of the medical needle point of common back of the body cut type.Like this, it is when carrying out the clinical treatment application of the aspect such as venous transfusion, injection, puncture indwelling and blood drawing to clinical user, because described needle point angle b greatly reduces and correspondingly greatly reduces penetration Resistance of the present utility model, so can greatly alleviate the pain degree of clinical user.

Above-described is only preferential embodiment of the present utility model.It should be pointed out that to those skilled in the art, not departing under the prerequisite of 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.
