Embodiment 1

[0064] Example 1: A safe insulin injection needle (with front and rear needle tip protection)

[0065] Such as Figure 1-14 As shown, the insulin injection needle is composed of a needle body 6, a needle base 2, a middle sleeve 3, a middle sleeve seat 31, an outer sleeve 8, a tail cap 1, a front sleeve 4, a trigger tube 5 and a spring 7 (see figure 2 ).

[0066] The structure of each part of the insulin injection needle of this embodiment is described in turn below:

[0067] 1. needle body 6

[0068] The needle body 6 is a tube needle used 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 direction, and a fixing section between the injection section and the connecting section .

[0069] 2. Header 2

[0070] The needle seat 2 is used to fix the needle body 6 (see Figure 4 , Figure 5 and Figure 6 ), the fixed section of the needle body 6 is fixed on the needle bas...

Embodiment 2

[0106] Example 2: Safe Insulin Injection Needle (With Front Tip Protection, Without Back Tip Protection)

[0107] The insulin injection needle consists of a needle body 6 , a needle seat 2 , a middle sleeve 3 , a middle sleeve seat 31 , an outer sleeve 8 , a front sleeve 4 , a trigger tube 5 and a spring 7 .

[0108] The difference between embodiment 2 and embodiment 1 is that the tail cap 1 is eliminated, and only the front needle point protection structure is provided, and the rear needle point protection structure is not provided. Others are basically the same as in Embodiment 1, and will not be described again here.

[0109] Relevant content and change description in the above embodiment are as follows:

[0110] 1. In the above two embodiments, the middle sleeve 3 and the middle sleeve seat 31 are separate structures, and then become a whole through the combination of sets, such design is for the consideration of processing technology. From the perspective of structure ...

Abstract

Provided is a safe insulin syringe needle. The safe insulin syringe needle comprises a needle body, a needle seat, a middle sleeve, a trigger tube, a front sleeve and a spring, and is characterized inthat the trigger tube is provided with an elastic arm, the needle seat is provided with a lug boss, when the needle is in use, the axial direction relative movement relation between the trigger tubeand the needle seat is used, the lug boss touches the elastic arm and forces the elastic arm to be deformed by being bent outwards to take up the position in front of the spring, so that the trigger tube can obtain temporary elastic recoil performance with the help of the spring within the distance of the movement of the trigger tube, and after the lug boss is separate from the elastic arm, the elastic recoil performance of the trigger tube is automatically relieved. The safe insulin syringe needle solves the problem that a single-spring structure adopted in a departed method cannot reserve the tentative elastic recoil performance of the trigger tube.

Description

technical field [0001] The invention relates to a medical insulin injection tool, in particular to a safe insulin injection needle. The injection needle can be used in conjunction with an insulin pen for self-administration or administration by others, wherein the insulin pen is reusable, and the injection needle is a one-time-use needle. Background technique [0002] Diabetes is a metabolic disease characterized by high blood sugar. There is currently no cure, but injecting insulin into patients can effectively control the disease. [0003] Insulin injection tools are various, and the insulin injection needle described in the present invention is an injection tool used in conjunction with an insulin pen, wherein the insulin pen carries a prescribed amount of insulin liquid medicine and is reusable, and the injection needle is a Single-use needles with safety guards. [0004] US2011 / 0257603A1 discloses an invention patent application titled "Safety Pen Needle Assembly with...
