Abstract
The utility model discloses a needle head for an injection pen, which comprises a needle seat, a needle tube and a protective cap, wherein the needle tube is arranged in the needle seat, the protective cap is fastened on the needle seat through a needle tip, the needle seat is sleeved with an outer protective sleeve on the outer portion of the protective cap, an opening end of the needle seat and the outer protective sleeve is thermally sealed with a bacteria retaining gluing dialyzing paper, the two ends of the needle tube are exposed with an injection needle tip and a puncture needle tip, and the needle tip of the puncture needle tip is not bigger than 45 degrees. The needle head for the injection pen uses a double-layer protective structure, the bacteria retaining gluing dialyzing paper which is thermally sealed on the opening end of the needle seat and the outer protective sleeve belongs to a single-use sterile product, the design protects the needle tip with an extremely fine diameter not to be damaged and to be sealed without bacteria, is safe and reliable, has low pollution rate, and has lower cost.
Description
Technical field
This utility model relates to medical apparatus and instruments safety injection field, particularly relates to a kind of safe and reliable injection pen syringe needle.
Background technology
Development along with the human health and the cause of guarantee, various medical apparatus and instruments have all had and upgrade largely and improve, the various injection needles that for example in clinical, are widely used, the most bore of traditional injection needle is bigger, in the process of injection, tend to produce pain in various degree, and much all be that intensive pain is arranged, therefore, people have developed the very thin syringe needle of diameter, reduce the pain in injection process, but this syringe needle on the market exists all very easily and can't be used by bending, and very easily contaminated shortcoming.
The utility model content
The purpose of this utility model is to provide a kind of injection pen syringe needle, and described injection pen is not only safe and reliable with syringe needle, and it is low to pollute probability, and cost is lower.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of injection pen syringe needle, it comprises needle stand, needle tubing and helmet, described needle tubing is arranged within the needle stand; described helmet is fastened on the needle stand; wherein, described needle stand also is arranged with oversheath outside helmet, and the opening of described needle stand and oversheath sealing heat seal matcoveredn.
Described needle tubing exposes at the two ends of needle stand injection needle point and needle tip, and the needle point of described needle tip is not more than 45.
Described protective layer is medical resistance bacterium gluing dialyzing paper.
The beneficial effects of the utility model are; the described injection pen employing double shielding structure of syringe needle; and opening sealing heat seal resistance bacterium gluing dialyzing paper in needle stand and oversheath; protecting the very thin injury-free and sealed, sterile of needle point of diameter to greatest extent; not only safe and reliable; the pollution probability is low, and cost is lower.
Description of drawings
With embodiment this utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the profile of this utility model embodiment injection pen with syringe needle.
The specific embodiment
Please refer to shown in Figure 1, this utility model provides a kind of injection pen syringe needle, this injection pen syringe needle and the supporting use of injection pen, can realize adjusting in advance injection volume, calibrated shot, accurate measurement, in present embodiment, described injection pen comprises needle stand 1 with syringe needle, needle tubing 2 and helmet 3, described needle tubing 2 is arranged within the needle stand 1, and described needle tubing 2 exposes at the two ends of needle stand 1 injection needle point 22 and needle tip 21, the needle point of described needle tip 21 is not more than 45, described helmet 3 is fastened on the needle stand 1 by needle tip 21, and described needle stand 1 also is arranged with oversheath 4 outside helmet 3, the opening sealing heat seal resistance bacterium gluing dialyzing paper 5 of described needle stand 1 and oversheath 4.
Described injection pen adopts helmet 3 and oversheath 4 double shielding structures with syringe needle; and opening sealing heat seal resistance bacterium gluing dialyzing paper 5 in needle stand 1 and oversheath 4; protecting the very thin injury-free and sealed, sterile of needle point of diameter to greatest extent; avoided syringe needle by the hidden danger of bending; not only safe and reliable; the pollution probability is low, and cost is lower.
