Abstract
The invention relates to a disposable novel bottle inserting needle, solving the problems of the existing bottle inserting needle that blockage can be easily caused by rubber particles and the needle tip during puncturing of a sealing cover of a transfusion bottle, the flow rate is low and instable, the transfusion efficiency can be affected, and the safety is poor. The needle tip part is provided with an inclined notch communicated with a pipeline, the rear end of the inclined notch is arranged on the wall of a straight pipe part, the front end of the inclined notch penetrates through the axial line of the straight pipe part and is arranged on a tapered body, and the intersection point of the inclined notch and the axial line is arranged behind the tip. Since the needle tip of the bottle inserting needle adopts a tapered shape and the intersection part of the straight pipe part and the needle tip part is provided with the inclined notch, the angle is reduced when the needle is inserted into a sealed bottle, the inserted needle can be prevented from being blocked, and the advantages of large flow rate and good anti-blockage effects can be achieved. Moreover, residues which are produced in the pipe after the inclined notch is processed can be easily cleaned and can be prevented from entering a human body along with liquid during transfusion to affect the physical health of the human body, and thus the safety can be improved.
Description
Technical field
The present invention relates to a kind of medical devices, be specifically related to a kind of novel disposable needle for inserting bottle.
Background technology
In clinical medicine is used; Transfusion has become and suppresses the state of an illness and continue development, guarantee health effectively, medicinal approaches easily, insert in the infusion bottle through the needle for inserting bottle on the transfusion device during use; Continue and stably get into vein, to replenish body fluid, electrolyte or nutrient substance is provided.
At present; The needle for inserting bottle of the common employing of medical domain can be divided into two forms basically, and is a kind of the most common for, needle point and inlet that the front end of its needle tubing forms for the inclination section; The axial of needle tubing is clear opening; So when insertion has in the infusion bottle of serum cap, cause rubber skin on the serum cap to get lodged in easily and cause the transfusion difficulty in the inlet, affect to transfusion.
Another kind adopts the front end inside of needle tubing to be hollow bullet for solving above-mentioned susceptible to plugging problem, and is arranged on inlet on the sidewall of needle tubing, stops up inlet so in needle for inserting bottle inserts infusion bottle, can prevent the rubber skin; But because inlet is arranged on the sidewall, the flow velocity of transfusion receives bigger influence, thus the efficient of influence transfusion; And during the inlet on the processing sidewall; Ccontainingly get lodged in some residues in the needle tubing, be difficult for cleaning, influence the health of human body when infusing causing after.
Summary of the invention
In order to overcome deficiency and the defective in the background technology; The present invention provides a kind of novel disposable needle for inserting bottle; Solved and form rubber particle easily when there is the seal cover of puncture infusion bottle in existing needle for inserting bottle and stop up, the little and de-stabilising effect of flow infuse efficient and the low problem of safety with needle point.
Technical scheme of the present invention is: a kind of novel disposable needle for inserting bottle; Comprise straight-tube portion and the tip portion that is positioned at the straight-tube portion front end; Said straight-tube portion inside is provided with pipeline; Described tip portion comprises cusp and is connected cusp and is provided with the angular cut that communicates with said pipeline with the said needle tip of the bullet of straight-tube portion office; The front end of said angular cut is positioned on the tip portion, and the rear end of said angular cut is positioned on the tube wall of straight-tube portion, and the intersection point of the axis of the plane at said angular cut place and straight-tube portion is positioned at the rear of said cusp.
The front end of said angular cut is positioned on the cusp.
Compared with prior art; The present invention has following beneficial effect: because the needle point of this needle for inserting bottle adopts cone-shaped, and the intersection that is employed in straight-tube portion and tip portion is provided with the angular cut of an inclination, makes to prevent that inlet is blocked in the syringe needle insertion infusion bottle; Thereby possesses big, the antifouling effective advantage of flow; And the residue that behind this angular cut of processing, produces in the pipe, can be cleaned easily totally, avoid when transfusion, getting in the body with liquid; Influence health, thereby improved safety.

Among the figure, straight-tube portion 1, tip portion 2, cusp 21, bullet 22, angular cut 3, axis 4, inlet 5.
The specific embodiment
To accompanying drawing embodiments of the invention are described further below:
Shown in figure; This novel disposable needle for inserting bottle comprises straight-tube portion 1 and the tip portion 2 that is positioned at straight-tube portion 1 front end, and said straight-tube portion 1 inside is provided with pipeline 11; Described tip portion 2 comprises cusp 21 and is connected the bullet 22 of cusp 21 with straight-tube portion 1; Said tip portion 2 places are provided with the angular cut 3 that communicates with said pipeline 11, form inlet 5 through angular cut 3, and the front end of said angular cut 3 is positioned on the tip portion 22; The rear end of said angular cut 3 is positioned on the tube wall of straight-tube portion 1, and the intersection point of the axis 4 of the plane at said angular cut 3 places and straight-tube portion 1 is positioned at the rear of said cusp 21.According to such scheme, because the needle point of this needle for inserting bottle adopts cone-shaped, and the intersection that is employed in straight-tube portion and tip portion is provided with the angular cut 3 of an inclination; Make syringe needle insert in the infusion bottle and prevent that inlet 5 is blocked, thereby possess big, the antifouling effective advantage of flow, and the residue that in these angular cut 3 back pipes of processing, produces; Can be cleaned clean easily; Avoid when transfusion, getting in the body, influence health, thereby improved safety with liquid.This needle for inserting bottle both can be connected with transfusion device, was used to be inserted into infusion bottle and realized the transfusion effect, and the molten medicine pin that can be used as again on the medicine dissolving device uses.
Shown in figure, the front end of said angular cut 3 is positioned on the cusp 21.The rear end that angular cut 3 is set is positioned on the tube wall of straight-tube portion 1, and the front end that angular cut 3 is set is positioned on the cusp 21, can effectively guarantee the antifouling effect that tip portion 2 is had, and can farthest realize the highest flow again.Angular cut 3 is stopped up by the rubber skin of Infusion bottle lid when preventing that syringe needle is inserted in the infusion bottle, thereby effectively guarantees transfusion efficient.The front end that angular cut 3 is set is positioned near cusp 21 bullets 22 and also can reaches ideal effect, but had better be positioned on the cusp 21.
Shown in figure, described tip portion 2 can preferably adopt ganoid conically shaped body certainly for slick conically shaped body or with stupefied bullet, helps needle point and is inserted in the infusion bottle easily.
Embodiment should not be regarded as the restriction to invention, but any improvement of doing based on spirit of the present invention, all should be within protection scope of the present invention.
