Embodiment 1
[0089] Example 1: Disposable safety insulin injection needle (with front needle tip protection and rear needle tip protection)
[0090] Such as Figure 1-10 As shown, the injection needle consists of a needle body 6, a needle seat 2, a main housing 3, an outer sheath 8, a tail cap 1, a front sleeve 4, a trigger tube 5 and a spring 7 (see figure 2 ).
[0091] The structure of each part of the disposable safe insulin injection needle of this embodiment is described in turn below:
[0092] 1. needle body 6
[0093] 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 .
[0094] 2. Header 2
[0095] 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 injecti...
Embodiment 2
[0164] Example 2: Disposable safety insulin injection needle (with front needle tip protection, without rear needle tip protection)
[0165] Such as 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 .
[0166] After fully understanding the insulin injection needle of Example 1, compared with Example 1, Example 2 only has a front-end needle tip protection structure and does not have a rear-end needle tip protection structure. Specifically, there are the following differences in structural design:
[0167] First, Embodiment 2 cancels the tail cap 1 in Embodiment 1;
[0168] Second, in embodiment 2, the two front legs 16 in the tail cap 1 of embodiment 1 are transplanted to the needle hub 2 of embodiment 1, see Figure 37 shown. Embodiment 2 retains the stopper 13 and the tentacles 11 provided on the front legs 16 . Embodiment 2 cancels the sharp-...

Abstract
The invention provides a disposable safe insulin injection needle head, which comprises a needle body, a needle seat, a main casing, an outer sheath and a triggering tube and is characterized in that the needle seat is formed by fixedly connecting a seat disc and a seat rod, the outer edge of the seat disc and the inner edge of the main casing have the sliding positioning connection relationship, i.e., during the injection needle head installation, the axial thrust of the head part of the insulin pin is used, so that the seat disc moves to a second positioning position from a first positioning position, the back part of the triggering tube is arranged on the seat rod in a sleeving way, the front end of the triggering tube is jacked and leaned on the inner end surface of the front part of the outer sheath, a third positioning structure is arranged between the triggering tube and the seat rod, and when the triggering tube is positioned in a third positioning position relative to the seat rod, the seat disc is positioned in the first positioning relative to the main casing; when the seat disc moves to the second positioning position from the first positioning position in the main casing, the triggering tube and the seat rod relieve the third positioning and form slide connection. The disposable safe insulin injection needle head has the advantages that whether the triggering tube is unlocked or not after being positioned or whether the injection needle head is prepared for the injection state or not are associated, and the use safety and the use convenience are improved.
Description
technical field [0001] The invention relates to a medical insulin injection tool, in particular to a disposable 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] Chinese patent CN101563124A discloses an invention patent application titled "needle pr...
