CN201008687Y - a needle for injection - Google Patents

Abstract

The utility model relates to a pinhead used for injection, and comprises a needle peduncle and a needlepoint. An injection channel is arranged in the needle peduncle. The key is that the outer surface of the needle peduncle is provided with a groove. The groove is arranged at the outer surface of the needle peduncle, thereby the touching area between the needle and the skin can be effectively reduced. The stimulation to the nerve ache can be reduced, and the ache of the person who is injected is further relieved. The effect is significant.

Description

a needle for injection

technical field

The utility model relates to a needle for injection.

Background technique

The injection needles in the prior art usually include a needle barrel and a needle point, and an injection liquid channel is arranged in the needle barrel. When in use, the drug is injected intramuscularly or intravenously by puncturing the skin of the subject to be injected. Because in clinical work, intramuscular injection or intravenous injection etc. all cause patient's pain, influence injection effect.

Utility model content

The utility model provides an injection needle aiming at the problems existing in the above-mentioned prior art, and the injection needle is used for intramuscular injection or intravenous injection and can relieve pain of patients.

The technical solution provided by the utility model is: a needle for injection, including a needle stem and a needle point, the needle stem is provided with an injection liquid channel, and the key point is that the outer surface of the needle stem is provided with a groove.

Above-mentioned groove is oval groove.

Above-mentioned groove is circular groove.

Above-mentioned groove is rectangular groove.

Due to the adoption of the above structure, the utility model can effectively reduce the contact area between the needle and the skin, reduce the stimulation to nerve pain, and further reduce the pain of the injected object by providing grooves on the outer surface of the needle shaft.

Detailed ways

Referring to Fig. 1-Fig. 6, the utility model includes a needle barrel 2 and a needle point 1, an injection channel 4 is arranged inside the needle barrel 2, and a groove 3 is arranged on the outer surface of the needle barrel 2. The groove 3 of the utility model can be a rectangular groove as shown in Figure 1 and Figure 2, can be an oval groove as shown in Figure 3 and Figure 4, and can also be a circular groove as shown in Figure 5 and Figure 6 Grooves or grooves of other shapes, etc.

The utility model can be used in intramuscular injection, intravenous injection or other injection fields. When the utility model is in use, it is installed on devices such as syringes the same as conventional injection needles, and is operated in a conventional manner. Because the utility model has grooves on the outer surface of the needle barrel, it can effectively reduce the contact area between the needle and the skin, reduce the stimulation of nerve pain, and further reduce the pain of the injected object, and the effect is remarkable.
