[0033] Example 1

[0034] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a medical local anesthetic patch comprises:

[0035] An anesthesia patch body 1, an anesthesia cloth 3 is arranged at the center of one side of the anesthesia patch body 1 (the side in contact with the arm), the anesthesia patch body 1 is also covered with a sealing patch 4 on the side provided with the anesthesia cloth 3, one end of the sealing patch 4 is fixedly connected to the anesthesia patch body 1, and the other end is connected to the anesthesia patch body 1 through a tear tape 5; a fold 6 is arranged at the fixed connection between the sealing patch 4 and the anesthesia patch body 1, a notch 7 is arranged at one end of the anesthesia patch body 1 near the fold 6, and the notch 7 is adapted to the size of the sealing patch 4, a main adhesive 9 is fixedly arranged on the side of the anesthesia patch body 1 near the sealing patch 4, and a secondary adhesive 10 is arranged on the side of the sealing patch 4 near the anesthesia patch body 1.

[0036] For further information, see Figure 5 As shown, in order to achieve the waterproof function of the anesthesia cloth 3, the anesthesia cloth 3 is arranged to be composed of a waterproof cloth layer 31, an anesthesia film layer 32 and a liquid medicine cotton layer 33, the liquid medicine cotton layer 33 is arranged on the side of the anesthesia cloth 3 close to the sealing patch 4, the waterproof cloth layer 31 is arranged on the side of the anesthesia cloth 3 away from the sealing patch 4, and the anesthesia film layer 32 is arranged between the liquid medicine cotton layer 33 and the waterproof cloth layer 31. When in use, the liquid medicine cotton layer 33 in contact with the arm is sequentially covered with the anesthesia film layer 32 and the waterproof cloth layer 31, which can play a waterproof role for the liquid medicine cotton layer 33. Even when the anesthesia patch body 1 is wet, the liquid medicine cotton layer 33 can be doubly waterproofed by the waterproof cloth layer 31 and the anesthesia film layer 32.

[0037] Furthermore, in order to realize a medical local anesthetic patch in the present embodiment, the anesthetic cloth 3 can be further isolated and protected when it is not activated. A protective cover 11 is fixedly provided at the center position of the sealing patch 4 close to the anesthetic cloth 3. The protective cover 11 covers the liquid medicine cotton layer 33 of the anesthetic cloth 3 and is adapted to the size of the liquid medicine cotton layer 33. The protective cover 11 covers the liquid medicine cotton layer 33 of the anesthetic cloth 3 and is adapted to the size of the liquid medicine cotton layer 33. When it is not activated, the protective cover 11 can completely cover the liquid medicine cotton layer 33 to protect the anesthetic cloth 3, thereby further reducing the reduction in anesthetic effect caused by the contact between the anesthetic cloth 3 and the air.

[0038] Furthermore, in order to facilitate the tearing of the tear strip 5 between the sealing patch 4 and the anesthesia patch body 1, a sealing patch pull ring 8 is fixedly provided on the side of the sealing patch 4 facing away from the anesthesia cloth 3; when in use, the sealing patch pull ring 8 can be pulled away from the anesthesia patch body 1 to tear the tear strip 5 between the anesthesia patch body 1 and the sealing patch 4, thereby making it more convenient to tear the anesthesia patch body 1 and the sealing patch 4 apart, thereby achieving an effect of convenient use.

[0039] Furthermore, in order to achieve a more stable structure of the anesthesia cloth 3 in the anesthesia patch body 1, an anesthesia port 2 is provided at the center of the anesthesia patch body 1, and the anesthesia cloth 3 is fixedly provided in the anesthesia patch body 1 through the anesthesia port 2, thereby making the contact area between the anesthesia cloth 3 and the anesthesia patch body 1 larger, thereby ultimately achieving a more stable connection and preventing the anesthesia cloth 3 from falling off from the anesthesia patch body 1.

[0040] Furthermore, in order to achieve a better adhesive fixing effect between the main adhesive 9 and the auxiliary adhesive 10, the main adhesive 9 is symmetrically arranged on both sides of the anesthesia cloth 3 along the length direction of the anesthesia patch body; the auxiliary adhesive 10 is symmetrically arranged on both sides of the protective cover 11 along the width direction of the sealing patch 4, and the main adhesive 9 and the auxiliary adhesive 10 are perpendicular to each other; when the main adhesive 9 fixes the anesthesia patch body 1 to the human arm, the sealing patch 4 is further wrapped and fixed on the anesthesia patch body 1 by the auxiliary adhesive 10, and the different positions and directions between the main adhesive 9 and the auxiliary adhesive 10 make the adhesive coordination effect between the vertically arranged main adhesive 9 and the auxiliary adhesive 10 better, and the main adhesive 9 and the auxiliary adhesive 10 cooperate with each other to be adhesively fixed from two different directions, so that the local anesthesia patch is adhesively fixed all around, and the fixing effect is better.

[0041] Furthermore, in order to prevent the protective cover 11 from being corroded by the liquid medicine cotton layer 33, the protective cover is made of a PE plastic film, and in order to make the anesthesia patch body 1 and the sealing patch 4 contact the human arm more softly and gently, the sealing patch 4 and the anesthesia patch body 1 are made of a gauze material;

[0042] According to a medical local anesthesia patch of this embodiment, before activation, the protective cover 11 on the sealing patch 4 can protect the anesthesia cloth 3 covered by the protective cover 11, and the anesthesia cloth 3 is divided into three layers, namely, a liquid medicine cotton layer 33, an anesthesia film layer 32 and a waterproof cloth layer 31, wherein the liquid medicine cotton layer 33 is arranged on the first layer on the front side (the side in contact with the human arm), and the second and third layers on the front side are the anesthesia film layer 32 and the waterproof cloth layer 31, respectively. The arrangement of the waterproof cloth layer 31 and the anesthesia film layer 32 can prevent the back side of the anesthesia patch body 1 (the side away from the side in contact with the human arm) from being exposed to water, which may cause a reduction in the anesthetic effect;

[0043] When in use, the sealing tape 5 connected between the anesthesia patch body 1 and the sealing tape is easily torn off by pulling the sealing tape pull ring 8 on the sealing tape 4 away from the anesthesia patch body 1. The tear tape 5 and the sealing tape pull ring 8 can be easily separated from the anesthesia patch body 1 and one end of the sealing tape 4, while the other end is fixedly connected and will not be disconnected. However, the sealing tape 4 and the other end of the anesthesia patch body 1 can be rotated around the fold 6 by the fold 6 at the other end, so that the torn end of the sealing tape 4 is rotated around the fold 6 with the fold 6 as the axis to open. After opening, the anesthesia cloth 3 in the anesthesia patch body 1 is aligned with the anesthesia patch body 1. In the arm area where the anesthesia patch is intoxicated, the anesthesia patch body 1 is first bent and fitted to the arm through the main adhesive 9. After the anesthesia patch body 1 is fixed, the end of the sealing patch 4 close to the notch 7 is inserted into the notch 7, and then the sealing patch 4 is fixed to the back side of the anesthesia patch body (the side away from the human arm) through the auxiliary adhesive 10 arranged perpendicular to the main adhesive 9, so that the sealing patch 4 is further fixed to the anesthesia patch body 1 through the auxiliary adhesive 10, and by clamping one end of the sealing patch 4 in the notch 7 arranged on the anesthesia patch body 1, the sealing patch 4 and the anesthesia patch body 1 are prevented from being misaligned and moved, thereby further increasing the fixing effect of the local anesthesia patch in this embodiment.
