Abstract

The invention discloses an insulin-used syringe needle with an adjustable injecting depth. The insulin-used syringe needle comprises a needle seat, a steel needle is connected in the needle seat through a bonding agent, internal threads for connecting the external threads on the front end of an insulin pen are arranged in the needle seat, a limit ring is sleeved on the needle seat, the external threads are arranged on the outer surface of the needle seat, the internal threads are arranged in the limit ring, and the needle seat and the limit ring is connected via engagement of the outer threads. The insulin-used syringe needle has the main beneficial effects that the risk of injecting into a muscle layer by mistake due to over-deep needle insertion is effectively prevented, a patient can adjust the injecting depth according to the self situation of fatness and thinness, so as to select the injecting depth suitable for self, and the practicability is strong.

Description

Injection depth scalable insulin syringe needle

Technical field

The present invention relates to a kind of injection depth scalable insulin syringe needle.

Background technology

Along with being on the increase of diabetics, daily injection of insulin is very frequent.Novopen is present insulinize injection tool commonly used, cooperates novopen to use with syringe needle, finishes subcutaneous injection.

The patient mainly chooses abdominal part when injection, arm, thigh, and buttocks, wherein the hypodermic layer of arm and thigh is thinner, injects after need to having pinched skin, and be easy to cause the insulin mistake to inject Musclar layer because the method for having pinched is improper, cause absorption of insulin too fast, glycemic control is unstable in the body, also can greatly increase patient's pain;

As shown in Figure 1, existing syringe needle is comprised of a plastics needle stand 1 and a draw point, and syringe needle is connected with the external screw thread of novopen front end by the female thread 11 of needle stand 1, and wherein draw point is undertaken bonding by glue and needle stand 1.Draw point front end 31 is for entering patient's hypodermic layer part, and insert in the rubber stopper of insulin injection pen draw point rear end 32, forms path with the insulin medicinal liquid; Because such syringe needle is so that draw point length is fixing can't regulate, when therefore injecting, depth of needle is held voluntarily by the patient; Simultaneously, because patient's fat or thin difference, its hypodermic layer thickness is also different, and the patient exists inserting needle excessively deeply to cause thrusting the risk of Musclar layer when injecting.

Summary of the invention

Purpose of the present invention solves the problems of the technologies described above, a kind of degree of depth that draw point enters human body that limits is proposed, effectively prevent because inserting needle causes the insulin mistake to inject the risk of Musclar layer excessively deeply, and the patient can regulate voluntarily according to the fat or thin situation of self, to choose the insulin syringe needle of the injection depth that is fit to oneself.

The present invention is achieved through the following technical solutions.

Injection depth scalable insulin syringe needle, comprise needle stand, be connected with a draw point by binding agent in the described needle stand, be processed with the female thread that connects for the external screw thread that connects the novopen front end in the described needle stand, be arranged with a spacing ring on the described needle stand, described hub outer surface is provided with external screw thread, is provided with female thread in the described spacing ring, and described needle stand and spacing ring are connected by internal and external threads.

Preferably, the front end of described needle stand offers external screw thread.

Beneficial effect of the present invention is mainly reflected in: 1) can according to patient's fat or thin adjusting injection depth, avoid because inserting needle causes insulin to inject the risk of Musclar layer excessively deeply;

2) can help the patient to gather hypodermic layer, avoid that to pinch under the bark fetching layer method improper because of the patient, cause insulin to inject the risk of Musclar layer;

3) make things convenient for the patient to operate alone, avoided the patient because the thinner need of hypodermic layer are pinched with hands and got, and the inconvenience that can't inject voluntarily.

The specific embodiment

The invention will be further described below in conjunction with drawings and Examples:

The present invention has disclosed injection depth scalable insulin syringe needle, such as Fig. 2-shown in Figure 3, consistent with prior art, comprise needle stand 1, be connected with a draw point 3 by binding agent in the described needle stand 1, the front end 31 of draw point 3 is used for inserting needle and contacts with patient's hypodermic layer, and the rear end 32 of draw point 3 communicates with the insulin medicinal liquid.Be processed with the female thread 11 that connects for the external screw thread that connects the novopen front end in the described needle stand 1.

Difference of the present invention is, also is arranged with a spacing ring 2 on the described needle stand 1, and the external screw thread 12 by described hub outer surface specifically is connected with the female thread 21 of spacing ring 2 interior settings.The front end of needle stand 1 is provided with external screw thread 12.Just can be so that spacing ring 2 seesaw with respect to needle stand 1 by rotation, and can regulate restriction to the length of draw point 3, use with the patient for different obese degrees.

Simultaneously, because the compressing power of 2 pairs of skins of spacing ring can impel hypodermic layer to gather, increase the thickness of fat deposit, be convenient to the patient and inject, avoided draw point 3 to thrust muscle and cause insulin to inject the risk of muscle.

The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within protection scope of the present invention.

Claims
