Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The purpose of the present invention is to provide a disposable high-strength non-invasive skin closure device to solve the above-mentioned technical problems in the prior art.

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

The present invention provides a disposable high-strength non-invasive skin closure device, comprising a scar removal sticker, a base plate 1, a base plate, a lock seat 3, a lock bar 4 and an unlocking structure. The substrate 1 is a plastic layer with limited deformation ability and good tensile strength. Here, a polyurethane material is selected, and rubber, latex, silicone or similar materials can also be selected. The base plate, the locking strip 3 and the locking base 4 are made of hard plastic, here nylon material is selected, and polypropylene, polyethylene, polycarbonate or similar materials can also be selected to provide sufficient strength. The lock base 3 and the lock bar 4 are both integrated on the substrate, which avoids the cumbersome installation process of the lock base 3 and the lock bar 4 and saves installation time. When the substrate is a corrugated substrate 2, the force can be more uniformly distributed on the substrate 1, and other types of substrates such as a linear substrate can also be used here as required.

As shown in FIG. 4 , the scar removal sticker is adhered to the lower surface of the substrate 1, and includes a pressure-sensitive adhesive layer 5, an upper water-absorbing layer 6, a magnet layer 7, a lower water-absorbing layer 8 and an artificial skin layer 9 that are sequentially arranged from top to bottom. . The magnet layer 7 helps to eliminate edema, reduce tissue organization, inhibit scarring and speed up the healing process. The chemical and biological properties of the artificial skin layer 9 are similar to those of human tissue, and do not produce rejection and toxic side effects, and effectively prevent scarring. The upper water-absorbing layer 6 and the lower water-absorbing layer 8 can well absorb the exudate from the human body and prevent blood and secretions from contaminating the clothes. Here, the upper water-absorbing layer 6 and the lower water-absorbing layer 8 are selected from water-absorbing resin, and also can be selected from hydrocolloid, hydrogel, acrylic polymer or similar materials. The upper water-absorbing layer 6 and the lower water-absorbing layer 8 are flexible and more elastic than the substrate 1 and the substrate, and maintain adhesion during the movement of the skin and tissue, preventing wrinkling and blistering. The base sheet is provided with ventilation holes to facilitate the ventilation of the tissue and prevent it from rotting and smelling. Since the scar removal sticker, the base plate 1 to the base sheet, the deformation ability is weakened from bottom to top, which not only provides a certain space for the subcutaneous tissue to move, but also prevents the excessive deformation from affecting the wound recovery.

The substrate is arranged on the upper surface of the substrate 1, and the lock seat 3 is arranged on the substrate. As shown in FIG. 3 , the lock base 3 is provided with a lock hole, and an elastic lock catch 31 is arranged in the lock hole for the lock bar 4 to pass through in one direction. The substrate, the lock bar 4 and the lock seat 3 are integrally formed, and the lock bar 4 and the lock seat 3 form an L-shaped structure. The lock bar 4 includes a fixed part 10 and a telescopic part, and the fixed part 10 is fixed on the lock base 3 . The telescopic portion is used to pass through the lock base 3 , and includes a locking tooth segment 11 and a non-locking tooth segment 12 . The locking tooth segment 11 is provided with locking teeth 111 , and the two ends of the non-locking tooth segment 12 are respectively connected to the locking tooth segment 11 and the fixing portion 10 . There are two substrates 1 , which are arranged opposite to each other, and a plurality of lock bases 3 and lock bars 4 are evenly distributed on each substrate 1 . Due to the existence of the non-locking tooth segments 12, the lock bases 3 on the two base plates 1 cannot be closely attached, and there is always a gap between them, which can be used for dressing changes and observing the healing of wounds, avoiding frequent disassembly and replacement. The lock seat 3 and the lock bar 4 can also be connected by a magic buckle, that is, the lock hole is divided into two parts in the cross-sectional direction, one part is provided with an elastic lock 31, the other part is not provided with the elastic lock 31, and there is no elastic lock. The partial width of 31 is greater than or equal to the width of the locking bar 4 . When it needs to be locked, keep the lock bar 4 in the locked state with the elastic lock 31. When it is not necessary to lock, move the lock bar 4 laterally to the part where the elastic lock 31 is not provided, and then the lock bar can be pulled out. No unlocking structure is required.

As shown in FIG. 5 , there are two unlocking structures. The unlocking structure includes a ridge portion 13 and a lateral extension portion 14 perpendicular to the ridge portion 13 . The lateral extension portion 14 is arranged corresponding to the lock seat 3 . Between the lock bar 4 extending into the lock hole and the elastic lock catch 31, the lock bar 4 can be taken out smoothly.

There are many ways to set the substrate, and the effects of each way are different, which will be described below with specific embodiments.

Embodiment 1,

As shown in FIGS. 1-5 , this embodiment provides a disposable high-strength non-invasive skin closure device, which includes all the above technical features. Further, as shown in FIG. 2 , the substrate is a corrugated substrate 2 , including a corrugated sheet and a corrugated substrate supporting portion 21 extending to another corrugated substrate 2 . The lock seat 3 and the fixing portion 10 are arranged on the corrugated substrate. on the sheet support portion 21 . Optionally, the corrugated substrate 2 may not include the corrugated substrate supporting portion 21, but only include corrugated sheets. In this case, the lock seat 3 and the fixing portion 10 are disposed on the upper surface of the corrugated sheet. The substrate 1 of the present embodiment is provided with a corrugated groove matching the shape of the corrugated substrate 2, and the corrugated substrate 2 is pasted in the corrugated groove.

The advantage of this setting method is that the corrugated substrate 2 is easy to install; the disadvantage is that when the corrugated substrate 2 is damaged, it is necessary to replace the disposable high-strength non-invasive skin closure as a whole, which not only increases the workload of medical staff, but also brings great harm to patients. Painful, and the waveform substrate 2 cannot be reused.

Embodiment 2,

As shown in FIGS. 6-7 , this embodiment provides a disposable high-strength non-invasive skin closure device, which is different from Embodiment 1 in that the lower surface of the corrugated substrate 2 is provided with protrusions 15 , and the upper surface of the substrate 1 is provided with protrusions 15 . The chute 16 that matches the protrusion 15. The cross section of the protrusion 15 is small and the bottom is large, and the upper surface of the substrate 1 is provided with a stepped limiting structure 17 for positioning the corrugated substrate 2 . Since the corrugated substrate 2 includes a special-shaped corrugated substrate supporting portion 21 , the stepped limiting structure 17 exists only on the curved edge portion of the corrugated substrate 2 , and the stepped limiting structure 17 is not provided near the corrugated substrate supporting portion 21 . .

When in use, first stick the two scar removal stickers on the lower surfaces of the two substrates 1 respectively, and stick the two scar removal stickers on both sides of the wound. Then, slide the protrusions 15 on the corrugated substrate 2 along the chute 16, and at the same time, the lock bar 4 will be gradually inserted into the lock seat 3 until the edge of the corrugated substrate 2 abuts against the stepped limiting structure 17. At this time, the relative movement of the two corrugated substrates 2 is restricted by the stepped limiting structure 17, the opposite movement is restricted by the lock bar 4 and the lock base 3, and the overturning rotation is restricted by the protrusion 15 and the chute 16, so that the corrugated substrate Sheet 2 can firmly lock the wound. When the corrugated substrate 2 needs to be removed, the lateral extension 14 of the unlocking structure is inserted between the lock bar 4 and the elastic lock 31 in the lock hole, and then the corrugated substrate 2 is pulled outwards so that the protrusions 15 along the The chute 16 can be slid out.

It should be noted that, if the corrugated substrate 2 adopts the setting method in Embodiment 1, when the two substrates 1 are close to each other, the lock bars 4 need to be inserted into the lock base 3 one by one, which is extremely cumbersome; At a distance, it is difficult to effectively protect the wound. In this embodiment, during the sliding installation process of the corrugated substrate 2, the lock bar 4 is inserted into the lock base 3 synchronously, and the operation process is simple and convenient.

Embodiment 3,

As shown in FIG. 8 , this embodiment provides a disposable high-strength non-invasive skin closure device, which is different from Embodiment 1 in that the limiting structure is a cylindrical structure 18 , and the cylindrical structure 18 is located on the two corrugated substrates 2 between. Compared with the stepped limiting mechanism in Embodiment 2, the process requirements of the cylindrical limiting structure are lower, the processing materials are saved, and the processing cost is reduced.

Embodiment 4,

As shown in FIG. 9 , this embodiment provides a disposable high-strength non-invasive skin closure device, which is basically the same in structure as that of Embodiment 1, and the difference is only in the number and arrangement of substrates. In this embodiment, a connecting piece 20 is also included, and both ends of the connecting piece 20 are respectively used to connect a substrate. The material of the connecting sheet 20 is the same as that of the base sheet. Here, nylon material is selected, and polypropylene, polyethylene, polycarbonate or similar materials can also be selected to provide sufficient strength. The substrate is a block substrate 19. Each substrate 1 is provided with a plurality of block substrates 19. Two adjacent block substrates 19 and a connecting piece 20 form a locking member. There are multiple locking pieces. The bulk substrate 19 may be adhered to the substrate 1 in an embedded manner, or may be directly adhered to the substrate 1 . The block substrate 19 can be in the shape of a regular square, a circle, etc. as required, and other regular or irregular shapes can also be selected. Here, a square block substrate 19 is selected.

Correspondingly, the block substrate 19 includes a square sheet and a block substrate support portion 191 extending toward another block substrate 19 . The lock seat 3 and the fixing portion 10 are disposed on the block substrate support portion 191 . Optionally, the block substrate 19 may not include the block substrate support portion 191 but only a square sheet. In this case, the lock base 3 and the fixing portion 10 are disposed on the upper surface of the square sheet.

The web 20 is only flexible enough to allow vertical flexing, and has a high tensile strength so as to minimize axial and lateral stretching and avoid the wound being affected by the pulling of the skin on both sides. The connecting piece 20 and the two block base pieces 19 together form a C-shape which in some embodiments can be opened axially to a certain extent in order to facilitate the base plate 1 on the two adjacent block bases of the adjacent locking members. Axial stretching between the sheets 19 is simultaneously limited to the axial stretching between the two block substrates 19 of a single locking member. In FIGS. 9-10 , the C-shaped structure faces outward, and the position of the connecting piece 20 can also be changed to make the C-shaped structure face inward.

The locking members on the two base plates 1 can be arranged in the opposite direction, as shown in FIG. 9 , or they can be arranged staggered, as shown in FIG. 10 . When the locking members on the two substrates 1 are disposed opposite to each other, the number of block substrates 19 on each substrate 1 is an even number. When the locking members on the two substrates 1 are staggered, the number of block substrates 19 on each substrate 1 is an odd number, and one block substrate not connected to the connecting plate 20 remains at the end of each substrate 1 19.

In this specification, specific examples are used to illustrate the principles and implementations of the present invention, and the descriptions of the above embodiments are only used to help understand the method and the core idea of the present invention; There will be changes in the specific implementation manner and application scope of the idea of the invention. In conclusion, the contents of this specification should not be construed as limiting the present invention.
