AI Technical Summary
Most existing acupuncture needles are made of non-degradable metal and need to be manually removed after use, which can easily cause discomfort to patients. Furthermore, traditional acupuncture only provides physical stimulation and does not combine with drug treatment. Drug treatment also needs to be absorbed through the gastrointestinal tract, which affects the targeting and systemic distribution.
A soluble sustained-release acupuncture needle was designed, consisting of a fish glue layer, a mesh drug storage layer, and an agarose layer. By combining physical stimulation with drug release, the drug release rate is regulated through the cavity structure within the agarose layer, thus achieving sustained drug release.
It improves the accuracy and duration of acupuncture treatment. The drug provides a stable concentration through the sustained-release mechanism of each layer of material, enhancing the therapeutic effect and reducing patient discomfort.

Abstract
Description
Technical fields:
[0001] This utility model relates to the field of medical devices, specifically a soluble sustained-release acupuncture needle. Background technology:
[0002] In the process of treating diseases, acupuncture and drug therapy are inevitably needed.
[0003] Current technological limitations include: most existing acupuncture needles are made of non-degradable metal, requiring manual removal after use, which can easily cause patient discomfort. Furthermore, traditional acupuncture needles only provide physical stimulation and fail to integrate with drug therapy, making them unsuitable for modern medical needs. Traditional drug therapy is mostly administered orally, requiring absorption through the gastrointestinal tract before entering the bloodstream. This process is affected by various factors, and once in the bloodstream, traditional drugs are distributed to various tissues and organs throughout the body. This can lead to adverse effects on non-target areas, thus leaving significant room for improvement. Therefore, we propose a "needle-drug combined" soluble sustained-release acupuncture needle. Utility Model Content:
[0004] The purpose of this invention is to provide a soluble sustained-release acupuncture needle to solve the problems mentioned in the background art.
[0005] This utility model is implemented by the following technical solution:
[0006] A soluble sustained-release acupuncture needle includes a handle and a body. The bottom of the handle is provided with a clamping mechanism, and the root of the needle body is inserted into the bottom of the handle and fixed by the clamping mechanism. The needle body includes a fish glue layer, a mesh drug storage layer and an agarose layer, which are arranged sequentially from the outside to the inside. The agarose layer has a cavity inside, and the cavity structure is "centipede-shaped".
[0007] Preferably, the clamping mechanism includes a movable groove, a cross groove, and a rubber band; the bottom circumferential surface of the needle handle is provided with a movable groove, the bottom end face of the needle handle is provided with a cross groove, the bottom end face of the needle handle is provided with a needle insertion hole, the cross groove and the needle insertion hole are connected, the rubber band is sleeved in the movable groove at the bottom of the needle handle, and the root of the needle body is inserted into the needle insertion hole.
[0008] Preferably, the depth of the pin hole is greater than the depth of the cross groove.
[0009] Preferably, the needle body is composed of a gelatin layer and an agarose layer, the needle body is infiltrated with a drug, and the gelatin layer covers the outer surface of the agarose layer.
[0010] The advantages of this invention are: through the combined effect of an innovatively designed needle-drug junction, controlled-release substances, and physical stimulation, and by combining physical stimulation with the chemical release of drugs from each layer of the needle, the therapeutic effect of acupuncture is significantly improved. The drug is continuously released during treatment through the sustained-release mechanism of the materials in each layer of the needle, providing a stable drug concentration, thereby improving the accuracy and duration of treatment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-6 This utility model provides a soluble sustained-release acupuncture needle technical solution:
[0020] Example 1
[0021] Please see Figure 1-4 and Figure 6A soluble sustained-release acupuncture needle includes a needle handle 1 and a needle body 2. The bottom of the needle handle 1 is provided with a clamping mechanism, which includes a movable groove 1.1, a cross groove 1.2 and a rubber band 3. The movable groove 1.1 is formed on the bottom circumferential surface of the needle handle 1, the cross groove 1.2 is formed on the bottom end face of the needle handle 1, and the needle insertion hole 1.3 is formed on the bottom end face of the needle handle 1. The cross groove 1.2 and the needle insertion hole 1.3 are connected, and the depth of the needle insertion hole 1.3 is greater than the depth of the cross groove 1.2. The root of the needle body 2 is inserted into the needle insertion hole 1.3. The rubber band 3 is fitted into the movable groove 1.1 at the bottom of the needle handle 1. The rubber band 3 has a ring-shaped structure and a circular cross-section, which facilitates the rolling of the rubber band 3 in the movable groove 1.1. By rolling the rubber band 3, the position of its location in the movable groove 1.1 is adjusted, causing the gap of the cross groove 1.2 at the bottom of the needle handle 1 to shrink, thereby clamping the root of the needle body 2 to achieve a fixed function. The structure is simple and easy to disassemble or replace the needle body 2.
[0022] To achieve the solubility of the acupuncture needle, the needle body 2 includes a fish glue layer 2.1, a mesh drug storage layer 2.2, and an agarose layer 2.3, which are arranged sequentially from the outside to the inside. The agarose layer 2.3 serves as the needle core of the needle body 2 to improve the overall hardness of the needle body 2.
[0023] It should be noted that the fish glue layer 2.1 is made of fish glue material, which can be gradually degraded in the human body.
[0024] The mesh-like drug storage layer 2.2 is also made of fish glue material, and the structure of the mesh-like drug storage layer 2.2 is mesh-like. It not only stores the therapeutic drug, but also connects the fish glue layer 2.1 and the agarose layer 2.3, so that the acupuncture needle remains stable during use, prevents drug leakage, and ensures the continuity and stability of drug release.
[0025] Agarose layer 2.3 is made from agarose, and the hardness of agarose layer 2.3 after solidification is greater than 800 g / cm. 2 This provides support for the fish glue layer 2.1, making it easier for the needle body 2 to pierce the skin.
[0026] A cavity 2.31 is formed inside the agarose layer 2.3, containing a therapeutic drug. The cavity 2.31 has a centipede-like structure, which helps to regulate the drug release rate by altering the dissolution rate of the structure, ensuring stable drug release and sustained therapeutic effect. After the needle 2, used to store the therapeutic drug, is inserted into the skin, the drug achieves a sustained-release effect as the agarose layer 2.3 gradually degrades within the skin.
[0027] Both fish glue and agarose are biocompatible natural materials that can be gradually degraded in the human body after entering the skin, without causing any irritation or damage to human tissues during the degradation process, meeting the requirements of modern medical treatment for material safety and effectiveness.
[0028] Example 2
[0029] Please see Figure 5 Compared with Example 1, Example 2 has the same overall structure. The difference is that the needle body 2 is composed of a fish glue layer 2.1 and an agarose layer 2.3. The fish glue layer 2.1 covers the outer surface of the agarose layer 2.3, so that the agarose layer 2.3 serves as the needle core of the needle body 2 to improve the overall hardness of the needle body 2. The length of the agarose layer 2.3 is at least 1 / 3 of the length of the needle body 2.
[0030] It should be noted that the fish glue layer 2.1 is prepared by mixing and solidifying fish glue material and therapeutic drugs, and the agarose layer 2.3 is prepared by mixing and solidifying agarose material and therapeutic drugs. The hardness of the solidified agarose layer 2.3 is greater than 800 g / cm. 2 The agarose layer 2.3 supports the gelatin layer 2.1, making it easier for the needle 2 to pierce the skin.
[0031] The two methods described above achieve the stepwise release of the drug, which works in conjunction with the physical stimulation of the needle body 2. During the treatment process, the dual therapeutic effects of "needle and drug combination" are achieved, which greatly improves the treatment effect and patient experience. Based on the reusable design of the needle handle 1, the economy and practicality of acupuncture needles are further optimized. The methods effectively solve the problems of uneven drug release and insufficient duration of drug effect in traditional acupuncture treatment, providing patients with more precise and continuous treatment effects.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
