Abstract
The utility model discloses an injection-depth-adjustable insulin needle head which comprises a needle stand, wherein a steel needle is connected in the needle stand through a binding agent; internal threads used for connecting external threads at the front end of an insulin pen are formed in the needle stand; the needle stand is sleeved with a spacing ring; external threads are formed in the outer surface of the needle stand; internal threads are formed in the spacing ring; and the needle stand and the spacing ring are occluded through the internal threads and the external threads. The insulin needle head mainly has the benefits that the risk that insulin is mistakenly injected into a muscle layer due to excessively deep needle insertion is effectively avoided; a patient can make adjustment according to the own fitness condition so as to choose a suitable injection depth; and the practicability is high.
Description
Technical field
This utility model 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, coordinates novopen to use with syringe needle, completes 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, in body, glycemic control is unstable, 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 pens draw point rear end 32, forms path with the insulin medicinal liquid; Draw point length is fixing can't regulate because such syringe needle makes, and when therefore injecting, depth of needle is held voluntarily by the patient; Simultaneously, due to 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.
The utility model content
The purpose of this utility model 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 from injecting the risk of Musclar layer because inserting needle causes the insulin mistake 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.
This utility model is achieved through the following technical solutions.
A kind of injection depth scalable insulin syringe needle, comprise needle stand, be connected with a draw point by binding agent in described needle stand, be processed with the female thread that connects for the external screw thread that connects the novopen front end in described needle stand, be arranged with a spacing ring on described needle stand, described hub outer surface is provided with external screw thread, is provided with female thread in 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.
The beneficial effects of the utility model are mainly reflected in: 1) can according to patient's fat or thin adjusting injection depth, avoid injecting the risk of Musclar layer because inserting needle causes insulin excessively deeply;
2) can help the patient to gather hypodermic layer, avoid that to pinch under bark fetching layer method improper because of the patient, cause insulin to inject the risk of Musclar layer;
3) facilitate 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.

Fig. 3: cross-sectional view of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is further described:
This utility model has disclosed a kind of injection depth scalable insulin syringe needle, 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 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 described needle stand 1.
Difference of the present utility model is, also is arranged with a spacing ring 2 on 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, due to 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, avoid draw point 3 to thrust muscle and cause insulin to inject the risk of muscle.
This utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming are within all dropping on protection domain of the present utility model.
Claims (2)
1. injection depth scalable insulin syringe needle, comprise needle stand, be connected with a draw point by binding agent in described needle stand, be processed with the female thread that connects for the external screw thread that connects the novopen front end in described needle stand, it is characterized in that: be arranged with a spacing ring on described needle stand, described hub outer surface is provided with external screw thread, is provided with female thread in described spacing ring, and described needle stand and spacing ring are connected by internal and external threads.
