[0018] Now the utility model will be further detailed in conjunction with the drawings.These drawings are all simplified schematic diagram, just with the schematic way the basic structure of the utility model is shown, so it just shows the constitution related with the utility model.

[0019] The utility model discloses a tension-reducing and antibacterial dressing for post-microtrauma scar.

[0020] Referring to Figure 1 And Figure 2The utility model relates to a kind of scar after minimally invasive surgery with tension-reducing antibacterial dressing, including elastic breathable bandage, microneedle base 1 and injection microneedle 2, microneedle base 1 is made of two injection shell seat 11, two injection shell seat 11 are arranged side by side, and mutually close one side edge flexible connection, can be moved around connecting place.

[0021] Refer to Figures 1 to 3 Injection microneedle 2 is densely distributed in the bottom surface of injection shell seat 11, and the inside of injection microneedle 2 is hollow to form an injection channel 22; the injection channel 22 is in communication with the drug cavity 111, and the injection microneedle 2 is used to pierce the human skin; the elastic breathable bandage is wrapped outside the microneedle base 1, and the microneedle base 1 is fixed to the human skin through the elastic breathable bandage.

[0022] The microneedle is mainly made of hyaluronic acid material, which is relatively hard after photocuring and can be gradually absorbed by the human body after piercing the human skin.

[0023] Refer to Figures 1 to 3 The outer wall of the injection shell seat 11 is arc-shaped in cross-section, and the two injection shell seats 11 are flexibly connected, so that the surrounding skin can be pulled while the required drug is injected by pressing on the patient, thereby reducing the tension in the scar area and facilitating the treatment of the scar.

[0024] Refer to Figure 2 And Figure 3 The length of the injection microneedle 2 arranged on the microneedle base 1 decreases from outside to inside, and the length of the injection microneedle 2 ranges from 3 to 5 mm; and the injection microneedle 2 on the microneedle base 1 is curved towards the middle part of the microneedle base 1, which is beneficial to the injection microneedle 2 piercing the patient's skin. The outer surface of the outermost injection microneedle 2 on the microneedle base 1 also forms a barb 21, which is made of the same material as the injection microneedle 2. The barb 21 is arranged to improve the adhesion of the injection microneedle 2 to the skin after piercing the skin.

[0025] The working principle of the utility model is as follows: according to the treatment requirements, anti-inflammatory analgesic or botulinum toxin is added to the microneedle base 1, and then the microneedle base 1 is pressed on the wound, and the two injection shell seats 11 are located on both sides of the wound; finally, the elastic breathable bandage is used to fix the injection base to the human skin and continuously press. When the injection microneedle 2 pierces the human skin, the surrounding skin can be pulled to reduce the tension in the scar area; in addition, the drug enters the human skin through the injection channel 22 of the injection microneedle 2 to treat the scar.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
