The release button is arranged on the shell 11, and the directional sliding groove is arranged on the mounting bracket 12.
When the puncture assembly 2 is in the ready state relative to the firing assembly 1, i.e. the state shown in fig. 4, the slider 14 is integrally connected with the puncture assembly 2 and compresses the elastic element 13 to be in the energy storage state, and at this time, the slider 14 is locked relative to the housing, and the corresponding puncture assembly 2 can also be stably in the ready state. The housing is further provided with a release unit 111 for unlocking, and when the puncture assembly 2 is unlocked, the elastic member 13 can release and push the puncture assembly 2 to move from the preparation position to the puncture position, namely the state shown in fig. 5. The launching component pushes the puncture component 2 to move from a preset position to a puncture position at a certain speed through the ejection mechanism, so that the pain of a user can be reduced, and the use experience is better.
The slider 14 and the housing may be locked in a snap-fit manner, and the corresponding release unit 111 is a release button disposed on the housing, and when the release button is pressed, the slider 14 and the locking mechanism are released and move to the puncturing position.
After the puncturing is completed, the puncturing unit is first moved together with the shooting assembly and separated from the application unit as shown in fig. 8, and then further separated from the shooting assembly as shown in fig. 9.
As shown in fig. 1, 4 and 5, the puncture needle assembly further comprises a protective cover 25, the protective cover 25 is detachably connected with the puncture assembly 2, and a cavity for inserting the hypodermic soft needle 221 is formed in the protective cover 25. The protective cap 25 provides an integral protection for the adhesive assembly 24, the piercing element 211 and the hypodermic needle 221. The protective cap 25 is preferably threadedly attached to the spike assembly 2.

As shown in fig. 10 and 11, the base 222 includes an adhesive surface, the hypodermic soft needle 221 is disposed on the base, and the adhesive surface is provided with the adhesive assembly 24. After the puncture assembly 2 is punctured into the skin, the puncture unit is adhered to the skin through the adhesion assembly 24, so that the subcutaneous soft needle 221 is ensured to be placed under the skin for a long time, meanwhile, the puncture area can be sealed, and bacterial infection, body fluid or blood backflow are avoided.

The score line 243 extends continuously from the outer edge of the barrier layer 242 to the initiation portion 244.
The isolation layer 242 can protect the adhesive layer 241, and ensure the bonding effect of the adhesive layer 241. Before the piercing, the release layer 242 needs to be removed from the adhesive layer 241. The common removal of the isolation layer 242 is performed gradually from the edge, but for the sealing of the adhesive, the adhesive assembly 24 needs to be disposed around the hypodermic soft needle 221, and if the adhesive is removed gradually from the edge, the hypodermic soft needle 221 will interfere with the removal of the isolation layer 242. Meanwhile, due to the thin subcutaneous soft needle 221 and the piercing element 211, the removal process of the isolation layer 242 may cause the piercing element 211 to deform, which may affect the subsequent use.
By providing the score line 243 on the separation layer 242 and providing the initiation portion 244 at the middle portion, when the separation layer 242 is removed, the initiation portion 244 is pulled, and the separation layer 242 is torn along the score line 243 while gradually separating from the adhesive layer 241, so as to avoid contact with the piercing element 211 and the hypodermic needle 221, and reduce mutual interference. The initiator 244 may be in the form of a ring-shaped structure disposed around the hypodermic needle 221.
As shown in fig. 10 and 11, the number of the score lines 243 is at least two, and two score lines 243 do not intersect with each other, and preferably at least two score lines 243 are distributed in a symmetrical manner with the hypodermic needle 221 as the center; in the process of removing the isolation layer 242, the isolation layer 242 is torn from multiple directions and separated from the adhesive layer 241, so that the stress is more uniform and the removal process is smoother.

When the protective sleeve 23 is axially separated from the hypodermic soft needle 221, the initiator 244 of the spacer 242 moves with the protective sleeve 23.
The protective sleeve 23 protects the penetrating element 211 and the hypodermic needle 221 and the protective sleeve 23 needs to be removed before penetration. The starting portion 244 corresponds to the protection sleeve 23, so that the isolation layer 242 can be removed simultaneously when the protection sleeve 23 is removed, and the operation convenience is excellent.
The protective sleeve 23 may be disposed outside the insulation layer 242 and connected to the insulation layer 242. It is also possible to provide a circumferential rim on the protective sleeve 23 while the protective sleeve 23 passes over the initiation 244, the circumferential rim being located inside the initiation 244, the circumferential rim initiating the initiation 244 in a synchronized movement when the protective sleeve 23 is removed, enabling removal of the barrier layer 242.
As shown in fig. 11, the starting portion 244 is further provided with guide holes 245 corresponding to the score lines 243 one by one, and one ends of the score lines 243 extend to the guide holes 245. When the initiator 244 is pulled, the separator 242 will tear accurately from the score line 243 due to stress concentration under the guidance of the guide hole 245. The guide hole 245 is preferably an arc-shaped hole around the center of the hypodermic soft needle 221.
A puncture method adopts the split type subcutaneous soft needle for application, which at least comprises the following steps:
firstly, connecting the puncture component 2 with the launching component 1, and adjusting the puncture component 2 to a preparation position relative to the launching component 1, wherein the puncture component 2 is locked relative to the shell;
step two, the protective cap 25, the protective sleeve 23 and the insulating layer 242 are removed from the puncture assembly 2;
thirdly, the subcutaneous soft needle 221 faces the skin of the part to be punctured, and the relative position between the puncturing component 2 and the skin is adjusted; the releasing unit 111 releases, the puncture unit 21 and the slider 14 are unlocked, the launching assembly 1 pushes the puncture assembly 2 to move from the preparation position to the puncture position until the subcutaneous soft needle 221 and the puncture piece 211 enter the skin, and the adhesive layer 241 is adhered to the skin;
step four, the puncturing unit is separated from the application unit 22, the piercing element 211 is synchronously withdrawn from the hypodermic soft needle 221, and the application unit 22 is further removed from the firing assembly 1, completing the puncturing.
