Description

Technical Field

[0001] The utility model relates to the field of soluble microneedle patches, in particular to a soluble microneedle patch with a puncture piece. Background Art

[0002] Soluble microneedle patches are made by making the active ingredients of drugs into micron-sized microneedles, and achieve the effect of efficient transdermal absorption by dissolving the drug needles in the skin. Soluble microneedles use patented microneedle technology to make active ingredients into micron-sized patches, which are directly applied to the skin for treatment. It can just pass through the stratum corneum without touching the pain nerves, and while promoting penetration, it does not cause pain or skin damage. It is safe, non-invasive, and painless to inject. It has a wide range of clinical uses and is suitable for the administration of biological drugs such as insulin, interferon, antibodies, and vaccines.

[0014] Furthermore, the thickness of the second waterproof layer is 0.2-0.3 cm.

[0015] The present invention provides a soluble microneedle patch with a puncture piece through improvement, which has the following improvements and advantages compared with the prior art:

[0016] First, the soluble microneedle patch with a puncture piece of the utility model is convenient for the microneedle puncture head body to puncture the patient's skin through the design of the adhesive patch, and convenient for the adhesive patch to be bonded to the patient's skin through the design of the adhesive patch, thereby avoiding the manual pressing method, which is easy to cause the pressing to loosen, thereby affecting the use effect of the soluble microneedle patch. At the same time, through the design of the drawstring, when the microneedle patch body needs to be disassembled, the microneedle patch body can be uncovered by pulling the drawstring;

[0017] Second: The soluble microneedle patch with a puncture element of the utility model has a tensile layer, an antibacterial layer, a first waterproof layer and a heat-resistant layer. A reinforcing plate is installed in a transverse arrangement inside the tensile layer, and a first reinforcing rib and a second reinforcing rib are installed in a transverse and staggered arrangement inside the tensile layer. Therefore, the tensile effect of the microneedle patch body is better through the reinforcing plate, the first reinforcing rib and the second reinforcing rib, thereby extending the service life of the microneedle patch body.
