Abstract
Disposable side opening intravenous needle.Mainly solved existing pin hole and only had one and establish the syringe needle of needle point, this syringe needle is mostly hollow pipe, and injection speed is slower, and penetration power is poor, easily causes blood outflow, and wound healing is slow, and pain is strong; And before using, need to recognize to, inconvenient problem with use.It is characterized in that: needle tubing is extended with syringe needle, syringe needle is filled circles cone structure, and needle tubing outer wall is provided with some pin holes, and needle tubing outer wall is extended with first and second smooth arc sliding face to pin hole is centroclinal, and both seamlessly transit.This utility model provides a kind of disposable side opening intravenous needle, and needle tubing bottom is solid needle point, and outer wall is provided with some pin holes, and injection speed is very fast, first and second smooth arc sliding face of pin hole oriented its extension around.During use, solid needle point penetration power is strong, and pain is light, and first and second arc sliding, in the face of angiolysis is little, goes out insufficiency of blood, and wound healing is fast.And needle point is conical, before use, do not need to recognize to, convenient and practical.
Description
Technical field
This utility model belongs to armarium, particularly disposable side opening intravenous needle.
Background technology
At present, what in hospital, mostly use is a kind of syringe needle that only has a pin hole and be located at needle point, and this syringe needle is mostly hollow pipe, and penetration power is poor, easily causes blood outflow, and wound healing is slow, and pain is strong; And before using, need to recognize to, use inconvenient.
Utility model content
In order to overcome the deficiency of background technology, this utility model provides a kind of disposable side opening intravenous needle, mainly solve existing pin hole and only had one and establish the syringe needle of needle point, this syringe needle is mostly hollow pipe, injection speed is slower, and penetration power is poor, easily causes blood outflow, wound healing is slow, and pain is strong; And before using, need to recognize to, inconvenient problem with use.
The technical scheme that this utility model adopts is:
A kind of disposable side opening intravenous needle, the needle tubing that comprises hollow, described needle tubing is extended with syringe needle, described syringe needle is filled circles cone structure, described needle tubing outer wall is provided with some pin holes, described needle tubing outer wall, to centroclinal the first smooth arc sliding face and the second arc sliding face of being extended with of pin hole, seamlessly transits between described first and second arc sliding face.
The tangent plane of described the first arc sliding face is 15 ~ 25 ° with the angle of the angle a that place, pin hole center plane becomes.
The tangent plane of described the second arc sliding face is 10 ~ 20 ° with the angle of the angle b that place, pin hole center plane becomes.
Described pin hole is elliptical shape.
Described pin hole is 3, and is centered close to same straight line.
Described needle tubing length is 35 ~ 40mm.
Described needle tubing diameter is 0.3 ~ 0.5mm.
The length of described syringe needle is 1.3 ~ 1.6mm.
The beneficial effects of the utility model are: this utility model provides a kind of disposable side opening intravenous needle, needle tubing bottom is solid needle point, needle tubing outer wall is provided with some pin holes, and injection speed is very fast, first and second smooth arc sliding face of pin hole oriented its extension around.During use, solid needle point penetration power is strong, and pain is light, and first and second arc sliding, in the face of angiolysis is little, goes out insufficiency of blood, and wound healing is fast.And needle point is conical, before use, do not need to recognize to, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the axonometric chart of an embodiment of this utility model.
Fig. 2 is the cutaway view of an embodiment of this utility model.
Fig. 3 is the A place enlarged drawing of Fig. 1 of an embodiment of this utility model.
Fig. 4 is the B place enlarged drawing of Fig. 2 of an embodiment of this utility model.
In figure, needle tubing 1, syringe needle 2, pin hole 3, the first arc sliding face 11, the second arc sliding faces 12.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: if Fig. 1 is in conjunction with as shown in Fig. 2 to Fig. 4, a kind of disposable side opening intravenous needle, the needle tubing 1 that comprises hollow, described needle tubing 1 is extended with syringe needle 2, described syringe needle 2 is filled circles cone structure, described needle tubing 1 outer wall is provided with some pin holes 3, and described needle tubing 1 outer wall, to centroclinal the first smooth arc sliding face 11 and the second arc sliding face 12 of being extended with of pin hole 3, seamlessly transits between described first and second arc sliding face.This utility model provides a kind of disposable side opening intravenous needle, and needle tubing bottom is solid needle point, and needle tubing outer wall is provided with some pin holes, first and second smooth arc sliding face of pin hole oriented its extension around.During use, solid needle point penetration power is strong, and pain is light, and first and second arc sliding, in the face of angiolysis is little, goes out insufficiency of blood, and wound healing is fast.And needle point is conical, before use, do not need to recognize to, convenient and practical, and its sharpness of more existing syringe needle has been heightened three one-tenth.
In this utility model, as shown in the figure, the tangent plane of described the first arc sliding face 11 is 15 ~ 25 ° with the angle of the angle a that pin hole 3 place, center planes become.When angle is positioned at this 15 ~ 25 ° of scopes, when syringe needle thrusts skin, stressed less, be more prone to thrust, keenly feel less.
In this utility model, as shown in the figure, the tangent plane of described the second arc sliding face 11 is 10 ~ 20 ° with the angle of the angle b that pin hole 3 place, center planes become.When angle is positioned at this 10 ~ 20 ° of scopes, when syringe needle thrusts skin, stressed less, be more prone to thrust, keenly feel less.
In this utility model, as shown in the figure, described pin hole 3 is elliptical shape.Oval-shaped pin hole is less to angiolysis, keenly feels little.
In this utility model, as shown in the figure, described pin hole is 3, and is centered close to same straight line.Such design can conveniently be injected, simple in structure, convenient and practical.
In this utility model, as shown in the figure, described needle tubing 1 length is 35 ~ 40mm.Size is convenient in the needle tubing use of this scope, and performance is more reliable.
In this utility model, as shown in the figure, described needle tubing 1 diameter is 0.3 ~ 0.5mm.Size is convenient in the needle tubing use of this scope, and performance is more reliable.
In this utility model, as shown in the figure, the length of described syringe needle 2 is 1.3 ~ 1.6mm.Size is convenient in the syringe needle use of this scope, and performance is more reliable.
Embodiment should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection domain of the present utility model.
