It is pointed out here that the following descriptions of the concepts are only for the purpose of making the content of the present application easier to understand, and do not represent the limitation of the protection scope of the present application.
[0037] Embodiment one:
[0038] A non-invasive skin anastomat lock device 4 for realizing bidirectional adjustment, as shown in Figures 1 to 4 , comprises an adhesive tape 1 arranged on both sides of a skin wound and a first fixing block 2 located on one of the adhesive tapes 1, the first fixing block 2 is connected with a zipper rack 3, further comprising a lock device 4 arranged on the other adhesive tape 1, the lock device 4 comprises at least one opening and closing fastener 401 which is realized by pressing and engaged with or released from the zipper rack 3, in the embodiment, the opening and closing fastener 401 is one, and a single finger pressing the opening and closing fastener 401 can realize the engagement and separation of the opening and closing fastener 401 and the buckle tooth 404, a second fixing block 402 located below the opening and closing fastener 401 and a rotating shaft body 403 located between the opening and closing fastener 401 and the second fixing block 402, the second fixing block 402 is provided with an opening in the middle for adjusting the distance of the zipper rack 3, or the second fixing block 402 is a hollow fixing block below.
[0039] It is worth mentioning that the second fixing block 402 can be a sticking block, which is essentially also used to fix the lock device 4 with the adhesive tape 1.
[0040] The opening and closing fastener 401 is provided with a buckle tooth 404 at the top end for engaging or releasing the zipper rack 3, and in the embodiment, the opening and closing fastener 401 is provided with a pressing area 405 at the top end for the user to press, and the zipper rack 3 is provided with a stop tooth 7 on the outer surface, which is arranged at the top end of the zipper rack 3.
[0041] The upper end of the zipper rack 3 is provided with a blocking tooth 7. When the pressing area 405 is pressed, the top buckle tooth 404 of the opening and closing buckle 401 is separated from the zipper rack 3, and the distance between the first fixed block 2 and the lock buckle device 4 is adjusted. When the pressing area 405 is not pressed, the opening and closing buckle 401 is clamped with the zipper rack 3 by the gravity of the opening and closing buckle 401, and the opening and closing buckle 401 and the rotating shaft body 403 form an integral lever to realize the up and down movement of the buckle tooth 404.
[0042] The pressing direction of the pressing area 405 is opposite to the running direction of the buckle tooth 404. When the pressing area 405 is pressed downward, the opening and closing buckle 401 is lifted upward and separated from the zipper rack 3, and the distance between the first fixed block 2 and the lock buckle device 4 is adjusted.
[0043] The combination of the rotating shaft body 403 and the clamping buckle has the following three forms:
[0044] The preferred mode is that the rotating shaft body 403 and the opening and closing buckle 401 are integrally molded. The rotating shaft body 403 can be a sheet. When the opening and closing buckle 401 is lifted upward by the pressing force of the pressing area 405, the sheet generates a downward pulling force on the opening and closing buckle 401. After the distance adjustment is completed, the pressing force is eliminated, and the opening and closing buckle 401 is pulled downward by the pulling force of the sheet and the gravity to be buckled with the buckle tooth 404 again.
[0045] The preferred mode is that, as shown in Figure 3 , the rotating shaft body 403 is an elastic body 5, and the opening and closing buckle 401 moves up and down with the elastic body 5 as the rotating shaft. In this embodiment, the elastic body 5 can be a spring or other elastic component. When the opening and closing buckle 401 is lifted upward by the pressing force of the pressing area 405, the elastic body 5 generates a downward springback force on the opening and closing buckle 401. After the distance adjustment is completed, the pressing force is eliminated, and the opening and closing buckle 401 is buckled with the buckle tooth 404 again by the springback force of the sheet and the gravity.
[0046] The preferred mode is that, as shown in Figure 4 , the rotating shaft body 403 is a columnar shaft body 6, and the opening and closing buckle 401 moves up and down with the columnar shaft body 6 as the rotating shaft. The columnar shaft body 6 can be connected in the second fixed block 402. When the opening and closing buckle 401 is lifted upward by the pressing force of the pressing area 405, the columnar shaft body 6 is lifted upward as the rotating shaft. After the distance adjustment is completed, the pressing force is eliminated, and the opening and closing buckle 401 is buckled with the buckle tooth 404 again by the gravity. When the pressing area 405 is not pressed, the gravity of the end of the buckle tooth 404 is greater than the part of the pressing area 405.
[0047] It is worth mentioning that the length distance between the pressing area 405 and the rotating shaft body 403 is greater than the length distance between the buckle tooth 404 and the rotating shaft body 403, and the lever principle is used to facilitate the user to lift the buckle tooth 404 with smaller force, realize labor saving, and improve the user's use comfort.
[0048] As shown in Figures 5 to 6 The stop tooth 7 includes a vertical surface 701 and an inclined surface 702, the vertical surface 701 facilitates the buckling of the buckle tooth 404, and prevents the buckle tooth 404 from slipping, the inclined surface 702 forms an acute angle of 30-40 degrees with the vertical surface 701, the stop tooth is shallow, which facilitates the distance adjustment of the zipper rack 3, and the distance between the stop teeth 7 is small, the gear selection is more abundant, and it is easier to adjust to the appropriate position.
[0049] The adhesive tape 1 on both sides is specifically medical PU on the top, medical adhesive in the middle, and release material on the bottom, which facilitates the protection of the adhesive before use.
[0050] A method for using a non-invasive skin anastomat lock device 4 for bidirectional adjustment, applicable to the above-mentioned needle-free skin surface anastomat lock device 4, the method comprises:
[0051] S1: Paste the adhesive tape 1 on both sides of the wound;
[0052] S2: The zipper rack 3 is inserted into the outlet through the first fixing block 2, so that the first fixing block 2 and the second fixing block 402 are fixed on the adhesive tape 1 respectively;
[0053] S3: One hand tightens the zipper rack 3, the user presses the first fixing block 2 with one finger such as the index finger, and presses the pressing area 405 with the other finger, the zipper rack 3 is pushed backward under stress, the buckle tooth 404 is lifted and slides to the next stop tooth 7 through the stop tooth;
[0054] Alternatively, both hands tighten the zipper rack 3, one hand presses the opening and closing buckle 401, and the other hand pushes the zipper rack 3 backward, the buckle tooth 404 is lifted and slides to the next stop tooth 7 through the stop tooth;
[0055] S4: One hand loosens the zipper rack 3, when the zipper rack 3 is in the buckling state, one finger is pressed towards the pressing area 405, the opening and closing buckle 401 is lifted, and the distance between the first fixing block 2 and the opening and closing buckle 401 is increased.
[0056] Example two:
[0057] The difference between the second embodiment and the first embodiment is that the pressing area 405 is pressed in the same direction as the running direction of the buckle tooth 404, and the connecting device is arranged between the opening and closing buckle 401 and the second fixing block 402, so that when the pressing area 405 is pressed upward, the opening and closing buckle 401 moves upward and separates from the stop tooth 7, and when the pressing area 405 is pressed downward, the opening and closing buckle 401 moves downward under the pressing force and its own weight and is clamped with the stop tooth 7.
[0058] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Those skilled in the art should understand that the present application includes but is not limited to the contents described in the drawings and the above specific embodiment. Any modification without deviating from the function and structural principle of the present application will be included in the scope of the claims.
