Abstract
The present invention provides a kind of enhanced medical fine puncture needle, including puncture tip, puncture tube and puncture needle pedestal, relative to traditional beveled tip type puncture needle, the enhanced medical fine puncture needle tip portion innovative design is the three rib type position of bone, when piercing through the buffer sealing parts such as medical silica-gel plug, puncture tip stress equalization, point of a knife is difficult flexural deformation, penetration power is strong, is particularly suited for occasion of the puncture needle outer tube diameter requirement less than 2mm；Injection moulding is used puncture needle more, puncture needle size is fine and during using traditional beveled tip type injection moulding, puncture tip part mould mould cavity manufacture difficulty and not easy mold release, the structure of the enhanced medical fine puncture needle of invention design can simplify production technology, mould is simple, it is easy to manufacture, puncture needle production cost can be effectively reduced, improve puncture needle manufacture yields.
Description
Technical field
The present invention relates to the brand-new design of medical fine puncture needle, the structure of traditional puncture needle is broken through, meet and puncture
The special occasions requirement that pin is minimized and puncture strength is high.
Background technology
Puncture needle is widely used in the puncture and liquid transmission of liquid bottle stopper and other liquids sealing silica gel part, when wearing
Pricker size is limited by hermetic unit silica gel size, when diametric requirements are smaller, using traditional beveled tip type puncture needle (ginseng
See accompanying drawing 2) requirement can not be met, when traditional beveled tip type puncture needle requires that tip is sharp, its gradient is larger,
Tip plastic rubber material is relatively thin and tip both sides unbalance stress, and tip is flexible when puncturing the parts such as silica gel, so that can not
Realize puncturing function, when applicable situation limited space requirement puncture needle size reduces, the problem is more protruded；Pass
System beveled tip type puncture needle tip mold cavity is irregular, and processing difficulties cause die cost high, and tip glue position
Relatively thin, the demoulding is difficult, and production fraction defective is very high, and quality is extremely unstable.
The content of the invention
The present invention provides a kind of enhanced medical fine puncture needle for above-mentioned technical barrier, and its structure includes puncturing
Tip, puncture tube and puncture needle pedestal, wherein puncture tip break through traditional beveled tip type structure, and innovative design is three
Trapezoid bit architecture, using the prismatic position of bone puncture needle when the seal members such as silica gel are pierced through, three position of bone are total to
With undertaking force of piercing, tip stress equalization can bear stronger force of piercing and tip will not the flexural deformation when piercing through,
The seals such as the bottle stopper with certain thickness and intensity can be smoothly punctured, when puncture needle external diameter is less than 2mm,
It becomes apparent relative to the tip configuration and strength advantage of traditional puncture needle；The enhanced medical fine puncture
Gap between three position of bone of needle tip can be after the seals such as silica gel be pierced through for the conveying of liquid；The enhancing
The medical fine puncture needle tip of type is prismatic position of bone structure, relative to traditional beveled tip type needle tip end structure more
It is rule, the corresponding needle tip shaping position processing of injection mold is simple and the demoulding is more easy to realize, reduces mould
Tool manufacturing cost, it is ensured that the product quality and yields of injection puncture needle.
Having the beneficial effect that relative to traditional puncture needle of the invention：The Rhizoma Sparganii of the enhanced medical fine puncture needle
Shape position of bone structure enhances the puncture ability of fine needle tip end position, fine needle tip end bit architecture rule
Then, the structure of the corresponding injection mold of simplification, it is easy to the demoulding, reduces die manufacturing cost, can effectively improve micro-
The yields of thin puncture needle manufacture.
Brief description of the drawings
Fig. 1 is enhanced medical fine puncture needle structure schematic diagram.
Fig. 2 is traditional beveled tip type puncture needle structure schematic diagram.
Wherein：1st, puncture tip；2nd, puncture tube；3rd, puncture needle pedestal；α, puncture tip taper angle.
Specific embodiment
Technical scheme is further described below in conjunction with accompanying drawing 1 and accompanying drawing 2.
As shown in Figure 1, enhanced medical fine puncture needle includes puncture tip 1, puncture tube 2 and puncture needle
Base 3, compared to traditional beveled tip type puncture needle as shown in Figure 2, the enhanced medical fine puncture needle
Puncture tip 1 uses prismatic position of bone structure, when the seal members such as silica gel are punctured, three position of bone stress equalizations
Flexural deformation is difficult, it punctures the more traditional beveled tip type needle tip end position of ability by force, and can bear bigger wearing
Thorn resistance；As shown in Figure 2, traditional beveled tip type lancet puncture tip 1 is received the left and right sides when puncturing
Sophisticated position is relatively thin when power is unbalanced and puncture needle is fine small size, puncture tip when piercing through the seal members such as silica gel
Yielding bending is held, sealing silica gel thickness and intensity are reached when to a certain degree, the tip deformation failure of puncture tip 1,
Effectively puncture can not be realized.As shown in Figure 1, enhanced medical fine 1 three, the lancet puncture tip
Position of bone gap portion be used to puncture after liquid conveying, liquid through puncture tube 2 and puncture needle pedestal 3 it is hollow in
Pipe is input into liquid-transport pipe-line；1 three position of bone tactical rules in the enhanced medical fine lancet puncture tip, can
The corresponding mould structure of simplification, reduces manufacturing cost, and mould is easy to the demoulding and can effectively ensure that the injection of puncture needle
Shaping yields.
Description above content is presently preferred embodiments of the present invention, it is intended to illustrate design philosophy of the invention and content,
This specification content should not be construed as limiting the invention.
