Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

It should be noted that, if the present invention relates to directional indication, such as terms of direction and orientation of up, down, left, right, front and back, it is to facilitate description of relative position relationship between members, and an absolute position that is not a relative position relationship between related members and members is specifically referred to, and is only used for explaining the relative position relationship between each member and motion situation under a certain specific posture, and if the specific posture is changed, the directional indication is changed accordingly.

As shown in fig. 1 to 14, the wound dressing support frame assembly of the present invention comprises a support frame assembly 100, a wound dressing assembly 200 is disposed at the bottom of the support frame assembly 100, the support frame assembly 100 comprises an upper adhesive patch 101 and a lower adhesive patch 102, the upper adhesive patch 101 and the lower adhesive patch 102 are connected by connecting areas 103 spaced along the long axis direction of the upper adhesive patch and the lower adhesive patch, a brace passing area 104 is formed between the adjacent connecting areas 103, and the wound dressing assembly 200 is fixedly disposed on the lower surface of the lower adhesive patch 102; the connection region 103 is an adhesive structure or a fusion connection structure. The upper adhesive patch 101 and the lower adhesive patch 102 are both of a sheet structure and have certain elastic deformation capability, and the thickness of the pull strip 301 in the wound closing unit 300 is generally not large, so that after the wound closing device is applied to the wound closing device, the wound closing unit 300 can freely pass through the pull strip passing area 104 between the upper adhesive patch 101 and the lower adhesive patch 102, and the closing effect is not influenced. The upper sticker 101 and the lower sticker 102 are both conventional sheet structures, so that the processing and manufacturing are convenient, the conventional bonding structure and the fusion connection structure can be implemented in a matching manner, and the complicated guide rail structure and the complicated sliding groove structure do not need to be processed. In addition, the upper adhesive sheet 101 and the lower adhesive sheet 102 have certain structural strength and certain width in the wound closing direction, so that the wound closing device can be limited in tensioning amount, namely, the skin sticking units 400 on two sides are limited in the minimum closing distance, the situation that the wound is excessively squeezed in the wound closing process can be prevented, and the aligning effect after the wound is closed can be improved. Of course, without loss of generality, the support frame assembly 100 of the present invention needs to have a certain structural strength to limit the pulling distance of the skin sticking units 400 on both sides, so that the corresponding upper adhesive patch 101 and lower adhesive patch 102 can be made of a material with relatively high strength, such as a plastic material.

It is understood that the connection regions 103 may be disposed at equal intervals, or may be disposed at any intervals according to the passage of the pull string, and the connection regions 103 are preferably disposed at uniform intervals in order to facilitate the penetration of the wound closure unit 300.

In a specific implementation, the adhesive structure may be an adhesive 105 or an adhesive layer disposed between the lower surface of the upper adhesive sheet 101 and the upper surface of the lower adhesive sheet 102; the upper adhesive sheet 101 and the lower adhesive sheet 102 are connected and fixed by the adhesive agent 105 or the adhesive layer which is distributed at intervals in the longitudinal direction. The advantages of this construction are the simplicity of manufacture and one of the disadvantages is that the adhesive 105 will spill out to spread or shift the adhesive layer and deform, which will change the predetermined position or shape of the connection area 103, resulting in a change in the predetermined position or shape of the strap passing area 104, which will directly affect the passing performance of the strap passing area 104. Another disadvantage is that when the wound dressing assembly 200 is replaced, the upper adhesive patch 101 and the lower adhesive patch 102 need to be disconnected from each other and the lower adhesive patch 102 and the wound dressing assembly 200 are removed from between the pull strip 301 and the wound 500, and the adhesive 105 or adhesive layer remaining on the upper surface of the lower adhesive patch 102 will adhere to or contaminate the lower surface of the pull strip 301 and actually affect the passage of the pull strip 301 in the pull strip passage area 104.

Referring to fig. 7 and 8, in order to overcome the above disadvantages, the present invention provides a preferred implementation manner of the bonding structure, in which the adhesive 105 is continuously coated on the lower surface of the upper patch 101 or the solid adhesive layer is disposed, and the surface of the upper patch is covered by the film 106, the film 106 is provided with holes along the long axis direction at intervals, the adhesive 105 or the solid adhesive layer in the hole area is used as the connection area 103, only the hole area of the film 106 is remained with the viscosity, and the upper patch 101 and the lower patch 102 are connected and fixed along the long axis direction at intervals. One of the advantages of the structure is as follows: the position and shape of the upper adhesive sheet 101 and the lower adhesive sheet 102 are defined by the position and shape of the opening of the connection area of the film 106, and the preset position or shape of the connection area 103 is not changed due to the excessive diffusion of the adhesive agent 105 or the displacement and deformation of the adhesive layer, thereby ensuring the stability of the preset position or shape of the brace passing area 104 and the passing performance of the brace passing area 104. Another advantage is that when the upper adhesive patch 101 is disconnected from the upper surface of the lower adhesive patch 102 during the replacement of the wound dressing assembly 200, the upper adhesive patch 101 and the adhesive 105 or adhesive layer and the covering film 106 are removed from the upper side of the pull strip 301 as a whole, and the adhesive 105 or adhesive layer does not remain on the upper surface of the lower adhesive patch 102, and the pull strip 301 is not contaminated by adhesion, thereby ensuring that the passage performance of the pull strip 301 in the pull strip passing area 104 is not affected.

In particular implementations, the fused attachment structure may be a heat fused attachment structure or an ultrasonic welded structure. The structure has the advantages of simple production and manufacture and the disadvantages that the connection and fixation of the upper adhesive patch 101 and the lower adhesive patch 102 are realized by matching with a sliding connector when the wound dressing assembly 200 is replaced.

Referring to fig. 9-11, to facilitate installation and replacement of the wound dressing assembly 200 in a sliding manner, the present invention provides a preferred sliding assembly implementation, wherein the wound dressing assembly 200 is secured to the lower surface of the lower adhesive patch 102 by a sliding connector 230; the sliding connection member 230 is composed of a main body 231 with an I-shaped cross section and a matching sliding member 232, and the main body 231 and the matching sliding member can freely slide along the length direction; the upper surface of the body member 231 is connected to the lower surface of the support frame assembly 100, and the lower surface of the mating slider member 232 is connected to the upper surface of the wound dressing assembly 200; the width of the edge of the upper structural layer 235 of the main body 231 is greater than the width of the outer edge of the upper surface of the mating slider 232; the lower structural layer 236 of the main body 231 is confined in the inner embracing groove 233 of the mating slider 232 and forms a clearance fit, i.e. the width and thickness of the edge of the lower structural layer 236 of the main body 231 is slightly smaller than the width and height of the inner embracing groove 233 of the mating slider 232; the edge of the lower structural layer 236 of the main body 231 is rounded or chamfered at the end to the side edge, and the mating slider 232 extends downward from the upper surface of the upper structural layer of the slider at the end in a wedge shape to the end edge of the lower surface of the lower structural layer of the slider. This construction has the advantage that it is very easy to remove the mating slider 232 and the wound dressing assembly 200 by sliding from the lower structural layer 236 of the i-shaped body member 231 when replacing the wound dressing assembly 200. This is because the edge width of the upper structural layer 235 of the main body 231 is greater than the width of the outer edge of the upper surface of the engaging sliding member 232, so that the upper structural layer 235 of the main body 231 is ensured to be inevitably located on the upper surface of the engaging sliding member 232 and not mistakenly enter the inner catching groove 233 of the engaging sliding member 232 when the engaging sliding member 232 is inserted. Meanwhile, a slope (i.e., a wedge-shaped surface 237 shown in the figure) is arranged at the end of the mating sliding member 232, that is, the slope extends downwards from the upper surface of the mating sliding member 232 to the end surface of the lower surface in a wedge shape, an arc-shaped smooth transition edge is arranged at the end of the lower structural layer 236 of the main body member 231, and the width and the thickness of the lower structural layer 236 are slightly smaller than the width and the height of the inner holding groove 233 and can freely slide; the actual using effect is as follows: because of the above-mentioned preset structure matching relationship, even if fine alignment is not required, the lower structural layer 236 can easily slide into the inner embracing groove 233, and when the wound dressing assembly 200 fixed with the matching sliding member 232 is replaced, the lower structural layer can be easily inserted into the inner embracing groove 233, so that the replacement of the wound dressing assembly 200 can be completed correctly. It will be appreciated that the above described sliding fit of the wound dressing assembly 200 is applicable to all types of support frame assemblies 100. The wound dressing assembly 200 can be directly attached to the lower surface of the lower adhesive patch 102 in addition to the indirect attachment via the sliding attachment 230 described above; this directly forms a wound dressing assembly 200 with the support frame assembly 100, and the wound dressing assembly 200 is typically adhesively secured directly to the lower adhesive patch 102.

The wound dressing assembly 200 of the present invention is an assembly that can be applied to a wound 500 to promote healing and recovery of the wound 500; for example, may consist of a hemostatic dressing or an antimicrobial dressing, or may consist of other bioactive dressings. In particular implementations, the wound dressing assembly 200 is comprised of a hemostatic dressing or an antimicrobial dressing and a porous film covering the dressing; the sealing mode of the edge of the porous capsule is heating fusion or ultrasonic welding, the manufacturing process is simple, and the use is convenient.

The upper sticker 101, the lower sticker 102 and the connecting area 103 of the present invention are made of transparent materials. This facilitates observation of the use or post-contamination condition of the dressing.

In order to improve the involution effect of the wound 500 and the smoothness of the wound 500 after healing, the base platform 201 with relative hardness higher than that of skin tissue is further arranged at the bottom of the wound dressing assembly 200, and the base platform 201 is just opposite to the base plane 202 of the bottom surface of the wound 500, which is a geometric standard plane; so that the reference plane 202 is closely attached to the skin surface of the wound 500 and the wound free skin edge at a zero distance, the original amorphous wound free skin edge is closely attached to the reference plane 202 in the vertical direction, and the wound free skin edge is forced to be aligned and leveled by relying on the reference plane 202, thereby improving the drawing alignment effect of the wound 500 and the smoothness after healing.

In addition, the utility model also provides a wound closing device, which comprises the wound dressing support frame component, a wound closing unit 300 and a skin sticking unit 400; the skin sticking unit 400 is used to stick and fix the skin surface on both sides of the wound 500; the wound closing unit 300 is connected with the skin sticking units 400 at both sides; the support frame assembly 100 is arranged between the two skin sticking units 400, and the middle part of the wound closing unit 300 is connected with the brace passing area 104 of the support frame assembly 100 in a matching way. In particular, after the wound closure device is installed, the support frame assembly 100 is positioned over the wound 500.

Generally, the skin sticking unit 400 may be composed of a flexible adhesive layer 401 for sticking on both sides of the wound 500 and a strip-shaped base tape 406 positioned on the adhesive tape 401 toward the wound 500 side; the support frame assembly 100 is arranged between the two flexible adhesive layers 401; the wound closure unit 300 connects the strip-shaped base strips 406 of the two skin adhesive units 400, and the middle portion of the wound closure unit 300 freely passes through the tape passing area 104 between the upper adhesive patch 101 and the lower adhesive patch 102. The strip 406 mainly functions to disperse stress so that it functions sufficiently, and the strip 406 is preferably a rectangular strip having a certain thickness, and the longitudinal axis direction of the strip 406 is arranged parallel to the longitudinal axis of the wound 500.

Referring to fig. 14, the skin attachment unit 400 may further adopt another preferred embodiment including a flexible adhesive layer 401 for directly attaching to the skin surface and a non-flexible adhesive layer 402 disposed on the upper surface of the flexible adhesive layer 401, the flexible adhesive layer 401 having an area larger than that of the non-flexible adhesive layer 402 and forming a soft edge region 403 which is not covered by the non-flexible adhesive layer 402 at the outer circumferential portion edge or the entire circumference edge of the flexible adhesive layer 401; in specific implementation, the wound closing unit 300 is connected with the non-flexible adhesive layer 2. Wherein, the layer 401 is pasted to flexibility is the one deck relatively more soft piece of pasting, if adopt flexible film adhesive tape or flexible glue to paste the area, it is for being used for pasting unit 400 to the skin surface of wound 500 periphery with skin, adopts the relatively soft material of flexibility simultaneously to be in order to improve the effective laminating degree between layer 401 and the skin is pasted to the flexibility, and the flexible deformation through the layer 401 is pasted to the flexibility guarantees the effective laminating with the skin. The non-flexible adhesive layer 402 is not completely non-flexible, which means that a layer of material which is more flexible and harder than the flexible adhesive layer 401 and is not easy to be pulled and deformed is formed, for example, a layer of dense polymer sheet material is arranged to play a role of conducting and dispersing wound pulling and closing force through the non-flexible adhesive layer 402, so that the pulling and closing force is more uniformly dispersed on the flexible adhesive layer 401, and the situation that skin tension is excessively concentrated due to excessive deformation of the single-layer flexible adhesive layer 401 is avoided; meanwhile, the pulling force can be uniformly dispersed to the edge part close to the periphery of the flexible pasting layer 401 through the non-flexible pasting layer 402, and then the strong suturing pulling force 'step reduction' is uniformly dispersed and applied to the skin surface in a large range through the transition effect of the soft edge region 403, so that the pulling-in force to the skin can be more uniformly dispersed, and the skin injuries such as skin strain, tension skin blister and the like caused by excessively concentrated skin stretching force are avoided. In order to improve the stress dispersion effect, it is also conceivable to add a strip-shaped base tape 406 on the upper surface of the non-flexible adhesive layer 402 near the wound side and connect the wound closing unit 300 with the strip-shaped base tape 406. The strip-shaped base tape 406 is mainly arranged to enable the edge of the non-flexible adhesive layer 402 close to the wound side to form a harder strip-shaped structure parallel to the wound with higher stress strength, so that the whole and uniform translational pulling on the wound edge can be further enhanced through the strip-shaped base tape 406 in the process of pulling the wound together, and the wound-closing alignment effect is improved. Without loss of generality, the strip-shaped base tape 406 should be made of a material with a hardness that is "harder" than the non-flexible adhesive layer 402, such as a high-density polymer plastic sheet or other hard material; meanwhile, when the strip-shaped base band 406 is arranged, the wound pulling and closing device can be further directly connected with the strip-shaped base band 406 and is connected with the non-flexible adhesive layer 402 through the strip-shaped base band 406 to transfer force.
