[0002] Closure of skin openings resulting from surgical incisions and accidental lacerations or wounds is critical to minimizing the risk of infection and promoting optimal healing of the wound or incision. To achieve this, wound closure must be performed quickly and the skin edges must be carefully approximated, so a device is needed to draw the two sides of the skin opening together to promote healing and reduce scar tissue formation.
[0003] The non-invasive closure devices currently used on the market mainly fix the skin on both sides of the wound through plastic buckles or medical tapes. The closure device can only simply fix the wound and cannot deal with the subsequent wound exudate, which will slow down the healing of the wound and even cause inflammation and infection of the wound. The closure device has no protection measures above the buckle, and it may be hooked by clothes and fall off during use, causing secondary damage to the wound. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] An embodiment of a non-invasive skin suturing device of the utility model:
[0024] A non-invasive skin suturing device, the specific structure of which is as follows Figure 1 As shown, it includes a first dressing body 1, a second dressing body 2 and a protective layer 6. A drawstring lock strip 3 is fixed to the first dressing body 1 through a lock strip fixing device 5, and a drawstring lock strip 4 is fixed to the second dressing body 2. A plurality of groups of latch teeth 7 are arranged at intervals along the length direction of the drawstring lock strip 3, and the protective layer 6 is arranged on the outside of the first dressing body 1 and the second dressing body 2.
[0025] The cross-section of the latch 7 is in the shape of a right triangle, with its longer right-angled side overlapping with the buckle lock strip 3, its hypotenuse facing the buckle lock buckle 4, and its shorter right-angled side facing away from the buckle lock buckle 4. The height of the cavity in the middle of the buckle lock buckle 4 is consistent with the tooth height of the latch 7, so when the buckle lock strip 3 is pushed into the buckle lock buckle 4, the hypotenuse of the latch 7 will undergo a small elastic deformation and can pass over the buckle lock buckle 4, but when subjected to a reverse pulling force, the right-angled side of the latch 7 will prevent the latch 7 from coming out of the buckle lock buckle 4.
[0026] The first dressing body 1 and the second dressing body 2 have the same structure and are both hydrocolloids. Hydrocolloids have extremely strong water absorption properties, can protect wounds, and provide a moist environment for wounds. In addition, hydrocolloids themselves have good self-adhesiveness and do not need to be fixed with tape.
[0027] The drawstring lock strip 3 is provided with easy-to-break holes 8 in a row along the width direction thereof, and the easy-to-break holes 8 are arranged on the far side of the farthest end latching teeth 7. Before use, the longer drawstring lock strip 3 is convenient for the user to insert it into the drawstring lock buckle 4. After the drawstring lock strip 3 and the drawstring lock buckle 4 are fixed in place, the overlong part of the drawstring lock strip 3 can be easily broken off through the easy-to-break holes 8, so as to avoid the overlong drawstring lock strip 3 affecting the patient's life.
[0028] Of course, in other embodiments, other styles of easy-to-break lines can be processed on the drawstring lock strip 3 to facilitate breaking the excessively long portion of the drawstring lock strip 3, such as opening a continuous shallow groove on the drawstring lock strip 3 as an easy-to-break line or opening an intermittent shallow groove on the drawstring lock strip 3 as an easy-to-break line.
[0029] The protective layer 6 is a medical tape, and its function is to completely cover the drawstring lock strip 3, the drawstring lock buckle 4 and the lock strip fixing device 5 from the outside after the drawstring lock strip 3 is broken, so as to prevent other objects from directly contacting the plastic drawstring and causing secondary damage to the wound. Of course, since the hydrocolloid itself is sticky, in other embodiments, the protective layer 6 can also be replaced by a non-sticky PVC film.
[0030] The end of the protective layer 6 is fixed on the first dressing body 1, and the other part is pasted with a tearable layer. After the tearable layer is torn off, the protective layer 6 can be completely covered with the drawstring lock strip 3, the drawstring lock buckle 4 and the lock strip fixing device 5 and then fixed on the second dressing body 2. Of course, the protective layer 6 can also be a part equipped separately, but when in use, the tearable layer needs to be torn off to cover the drawstring lock strip 3, the drawstring lock buckle 4 and the lock strip fixing device 5.
[0031] The usage process of the utility model is as follows: when in use, one of the first dressing body 1 and the second dressing body 2 is glued to the wound, and the other is glued near the wound, the drawstring lock strip 3 is inserted into the drawstring lock buckle 4 and the drawstring lock strip 3 is pulled to generate sufficient pulling force at the wound, and then the excessively long part of the drawstring lock strip 3 is broken off, and the protective layer 6 is used to completely cover the drawstring lock strip 3, the drawstring lock buckle 4 and the lock strip fixing device 5 from the outside.
[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
