Abstract
The utility model discloses a special blunt needle tube for dispensing, which comprises a needlepoint dip angle Alfa ranging from 40 to 50 degrees. The blunt needle tube is specially designed for dispensing rather than injection, however, the processing method thereof is the same with that of the traditional needle tube, so that no extra cost is generated. The blunt needle tube has the characteristics of simple and practical structure.
Description
Technical field
This utility model relates to a kind of needle tubing, particularly a kind of special-purpose blunt nosed needle tubing that makes up a prescription.
Background technology
The industry standard YY 0029-90 of the People's Republic of China (PRC) is for the regulation of disposable use venoclysis needle, the needle point inclination alpha of needle tubing ' value be 17 °, limit deviation is ± 2 °, its structure as shown in Figure 1.It is so little why this inclination angle is designed, be to be same needle tubing because existing make up a prescription needle tubing and injection needle adopt, the design of this inclination angle is exactly the puncture degree in order to guarantee to inject, reduce patient's pain, but in the process of making up a prescription, because the needle point inclination angle is less than normal, needle point is quite sharp-pointed, the contact area of needle point when piercing through the injection plug is little, makes that the stress ratio of unit are is bigger, and it is very fast that needle point passes the speed of injection plug, in this process, relatively be easy to generate debris of rubber stopper, and debris of rubber stopper can enter with needle tubing and sneaks into medicament, and medicament is polluted, and this can bring harm to the patient to a certain extent.
The utility model content
At the problems referred to above, this utility model has designed a kind of special-purpose blunt nosed needle tubing that makes up a prescription, and it reduces the speed of passing the injection plug by the inclination angle that increases needle point, has greatly reduced the generation of debris of rubber stopper, has simple and practical characteristics.
For achieving the above object, this utility model is by the following technical solutions:
A kind of special-purpose blunt nosed needle tubing that makes up a prescription comprises a needle point inclination alpha, it is characterized in that: the angular range of described α is 40 °～50 °.
Further, the best angle of above-mentioned α is 45 °.
Needle point of the present utility model inclination angle is compared the industry standard regulation and has been increased more than one times, the contact area of needle point when piercing through the injection plug heightened, and then make and under same function power, significantly reduced the stress on the unit are, slowed down puncture speed, can effectively avoid the generation of injection debris of rubber stopper, significantly reduced the generation of debris contamination medicament phenomenon, avoided the patient is produced harm.
Description of drawings
The planar structure sketch map at the needle tubing syringe needle inclination angle of Fig. 1, industry standard regulation;
The planar structure sketch map at Fig. 2, needle tubing syringe needle of the present utility model inclination angle.
The specific embodiment
As shown in Figure 2, a kind of special-purpose blunt nosed needle tubing that makes up a prescription comprises a needle point inclination alpha, and the angular range of described α is 40 °～50 °, and its best angle is 45 °.
Needle point of the present utility model inclination angle is compared 17 ° ± 2 ° of industry standard regulation and has been increased more than one times, the contact area of needle point when piercing through the injection plug heightened accordingly, and then make and under same function power, significantly reduced the stress on the unit are, slowed down the puncture speed of needle point, can effectively avoid the generation of injection debris of rubber stopper, significantly reduced the generation of debris contamination medicament phenomenon, avoided the patient is produced harm.
This utility model designs for making up a prescription specially, be not suitable for injection and use, but its processing method is the same with conventional syringe, can additionally not produce surcharge, has simple and practical characteristics.
Claims (2)
1. the special-purpose blunt nosed needle tubing that makes up a prescription comprises a needle point inclination alpha, it is characterized in that: the angular range of described α is 40 °～50 °.
2. the special-purpose blunt nosed needle tubing that makes up a prescription as claimed in claim 1, it is characterized in that: the best angle of described α is 45 °.
