Embodiment 1
[0107] Example 1: An insulin injection needle with front-end needle tip protection and rear-end needle tip protection
[0108] like Figure 1-10 As shown, the injection needle consists of a needle body 6, a needle seat 2, a main casing 3, an outer sheath 8, a tail cover 1, a front sleeve 4, a trigger tube 5 and a spring 7 (see figure 2 ).
[0109] The structure of each component of the insulin injection needle of this embodiment is described in sequence below:
[0110] 1. Needle 6
[0111] The needle body 6 is a tube needle for injecting insulin, and the needle body 6 has an injection section extending toward the front end, a connecting section extending toward the rear end, and a fixing section between the injection section and the connecting section. .
[0112] 2. Needle seat 2
[0113] The needle seat 2 is used to fix the needle body 6 (see Figure 4 ), the fixed section of the needle body 6 is fixed on the needle base 2 , the injection section of the needle body 6...
Embodiment 2
[0182] Example 2: An insulin injection needle with front-end needle tip protection
[0183] like Figure 36 As shown, the injection needle consists of a needle body 6 , a needle seat 2 , a main housing 3 , an outer sheath 8 , a front sleeve 4 , a trigger tube 5 and a spring 7 .
[0184] After fully understanding the insulin injection needle of Example 1, Example 2 only has a front-end needle tip protection structure compared with Example 1, and does not have a rear-end needle tip protection structure. Specifically, there are the following differences in structural design:
[0185] First, Embodiment 2 cancels the tail cover 1 in Embodiment 1;
[0186] Second, in Example 2, the two front legs 16 in the tail cap 1 of Example 1 were transplanted to the needle seat 2 of Example 1, see Figure 37 shown. Embodiment 2 retains the stopper 13 and the toe hook 11 provided on the front leg 16 . Embodiment 2 cancels the sharp-angled tenon 14 provided on the front leg 16 .

Abstract
The invention relates to an insulin syringe needle with a needle tip protection function. The insulin syringe needle comprises a needle body, a needle seat, a main shell and an outer jacket, and is characterized in that a trigger pipe, a front casing pipe and a spring are arranged in the main shell, the trigger pipe is used for protecting an injection section of the needle body before the application, and the front casing pipe is used for protecting the injection section of the needle body after the application. Before the application, the trigger pipe stretches out of the main shell and stays at a needle body protection stage, and the front casing pipe is arranged in the main shell; after the application, the trigger pipe is arranged in the main shell, the front casing pipe stretches out of the main shell and stays at a needle body protection state. The unlocking of the trigger pipe and the front casing pipe is correlated to the state whether the syringe needle is prepared for injection or not, and the unlocking of the trigger pipe and the front casing pipe is triggered by utilizing a tail cover and the needle seat when in installation, and safety and convenience in use can be improved.
Description
technical field [0001] The invention relates to a medical insulin injection tool, in particular to a disposable and safe insulin injection needle with needle tip protection. The injection needle can be used for self-administration or other people's administration when used together with an insulin pen, wherein the insulin pen is reusable, and the injection needle is a single-use needle. Background technique [0002] Diabetes is a metabolic disease characterized by hyperglycemia. There is no cure for it, but injecting insulin to patients can effectively control the disease. [0003] There are various insulin injection tools, wherein the insulin injection needle of the present invention is an injection tool used together with an insulin pen, wherein the insulin pen carries a prescribed amount of insulin liquid medicine and can be reused, and the injection needle is a kind of injection tool. Disposable needle with safety guard. [0004] Chinese patent CN101563124A discloses a...
