[0034] Please refer to Figure 1-Figure 4 Some embodiments of the present application provide an insulin needle for injecting insulin, the insulin needle comprising: a needle seat 1, an injection needle 2, an elastic member 3, a needle protection sleeve 4 and a needle protection hose 5;
[0035] The needle seat 1 has a needle body cavity 13, and the injection needle 2 is fixed in the middle of the needle body cavity 13, and its bottom end extends out of the needle seat 1;
[0036] The needle guard 4 is slidably mounted in the needle seat 1 and surrounds the injection needle 2;
[0037] The elastic member 3 is disposed in the needle body cavity 13, and the two ends thereof respectively press the needle seat 1 and the needle guard sleeve 4 so that the needle guard sleeve 4 is pressed downward and extends out of the needle seat 1;
[0038] The needle protection hose 5 is sleeved on the injection needle 2 , and its bottom end covers the bottom end of the injection needle 2 .
[0039] Specifically, the insulin needle of the embodiment of the present application is used for injecting insulin, and it needs to be used in conjunction with an insulin pen. The usage process is: install the insulin needle of the embodiment of the present application on the insulin pen, so that the top end of the injection needle 2 punctures and inserts into the pen core (a carrier for storing insulin liquid) in the insulin pen, and the bottom end of the injection needle 2 based on the insulin needle punctures and inserts into the patient's body, and then pushes the insulin pen so that the insulin liquid in the pen core is injected into the patient's body through the insulin needle.
[0040] More specifically, when not in use, the outer side of the insulin needle of the embodiment of the present application is covered with a needle protection hose 5 that completely wraps the needle tip at the bottom end of the injection needle 2, and the needle protection hard sleeve 4 naturally extends out of the needle body cavity 13 and surrounds the bottom end of the injection needle 2 under the compression of the elastic member 3, which can effectively protect the injection needle 2 and prevent the injection needle 2 from touching foreign objects and being deformed or contaminated.
[0041] The working principle of the insulin needle in the embodiment of the present application: during the process of the bottom end of the injection needle 2 of the insulin needle piercing and inserting into the patient's body, the needle protection sleeve 4 retracts into the needle body cavity 13 and compresses the elastic part 3 under the blocking effect of the human skin, and at the same time, the needle protection hose 5 is also compressed under the blocking effect of the human skin, so neither the needle protection sleeve 4 nor the needle protection hose 5 affects the injection of insulin; after the insulin injection is completed, the medical staff pulls out the insulin needle, and the needle protection hose 5 recovers under its own elastic resetting effect, so that the bottom end of the needle protection hose 5 covers the bottom end of the injection needle 2 again, ensuring that the needle hole of the injection needle 2 is not exposed after the insulin needle is separated from the human body, effectively preventing the medical staff from being injured and infected due to touching the needle end of the injection needle 2 due to careless operation.
[0042] The insulin needle in the embodiment of the present application is provided with a needle protection sleeve 4 and a needle protection hose 5 to provide double protection for the injection needle 2, which can effectively prevent the injection needle 2 from being damaged and deformed before use; after use, the needle protection hose 5 can automatically restore to cover the bottom end of the injection needle 2, preventing the needle hole of the injection needle 2 from being exposed and injuring medical staff, thereby effectively improving the safety of the use of the insulin needle.
[0043] In some preferred embodiments, the needle seat 1 has a fixing column 111 located in the needle body cavity 13, the injection needle 2 is fixed on the fixing column 111, and the top end of the needle protection hose 5 is sleeved and fixed on the bottom of the fixing column 111 to be sleeved on the injection needle 2.
[0044] Specifically, the needle protection hose 5 is sleeved and fixed on the fixing column 111, which can ensure that the needle protection hose 5 is restored based on the connection position between it and the fixing column 111 to ensure that its bottom end can cover the bottom end of the injection needle 2 again.
[0045] More specifically, the fixing column 111 , the injection needle 2 , the needle protection hose 5 , and the needle body cavity 13 are all coaxially arranged, so that medical personnel can accurately grasp the puncture insertion position of the injection needle 2 .
[0046] In some preferred embodiments, the bottom of the fixing column 111 has a slot 112 for cooperating with the top end of the needle guard hose 5, and the portion of the fixing column 111 below the slot 112 shrinks downward.

[0056] Specifically, the upper shell 11 is preferably interference fit with the lower shell 12 .
[0057] More specifically, dividing the needle seat 1 into an upper shell 11 and a lower shell 12 can facilitate the assembly of the insulin needle of the embodiment of the present application. The specific assembly process is: fix the injection needle 2 in the upper shell 11, and put the needle protection hose 5 on the injection needle 2, and then place the needle protection sleeve 4 and the elastic member 3 on the lower shell 12, and finally snap-fit and fix the lower shell 12 to the upper shell 11 to complete the assembly of the insulin needle of the embodiment of the present application.
[0058] In some preferred embodiments, the inner side of the bottom of the lower shell 12 has a buckle edge 121 for preventing the needle guard 4 from slipping off.
[0059] In some preferred embodiments, the elastic member 3 is a spring, and both the needle seat 1 and the needle guard sleeve 4 are provided with a limiting groove 31 for limiting the installation position of the spring end, which can effectively prevent the spring installation position from shifting and causing the needle guard sleeve 4 to shake.
