Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical supplies, in particular to a tracheostomy incision dressing. BACKGROUND

[0002] Tracheostomy is a medical procedure to create an artificial airway in the neck of a patient. When the patient's condition improves and no longer needs a tracheal tube, the tracheal tube needs to be removed. After extubation, a tracheostomy incision is left in the patient's neck.

[0003] Currently, there are limited ways to handle such incisions. One way is to cover it with ordinary dressings and rely on its self-healing, but this will result in a longer healing time, and the exposure of the incision increases the risk of infection, and the scar formed after healing is larger. Another way is to perform surgical suturing, but this will bring additional trauma and pain to the patient, and the operation is relatively complex.

[0004] Existing skin closure devices, such as some zipper or strap closure devices, are mainly used to close linear surgical incisions. For this round or irregular hole-shaped incision left by tracheostomy, there is a lack of specialized, non-invasive, and effective closure tools that can gather the surrounding skin towards the center.

[0005] Therefore, there is a need in the art to provide a device that can safely, comfortably and effectively close the tracheostomy incision after extubation. SUMMARY

[0006] The purpose of the present application is to provide a tracheostomy incision dressing after extubation, which can gather the skin around the incision towards the center in stages, firmly and comfortably, to close the incision and promote healing.

[0007] The above technical purpose of the present application is achieved by the following technical solution: a tracheostomy incision dressing after extubation, comprising: a dressing sheet covering and adhering to the incision; a plurality of buckles arranged around the dressing sheet for preliminary gathering of the skin around the incision; a plurality of zipper assemblies arranged around the dressing sheet and arranged at the periphery of the plurality of buckles for strong closure of the incision.

[0008] Further, a strap is provided, one end of which is connected to the dressing sheet, and a loop is provided on the strap, and the other end of the strap is provided with a first adhesive part and a second adhesive part; The other end of the strap can pass around the patient's neck, with the first adhesive part passing through the loop and then being folded back, so that the first adhesive part and the second adhesive part are adhered and fixed.

[0009] Further, each of the buckles comprises: a first fixing seat fixed to the application patch; an arch bridge arranged on the first fixing seat; a second fixing seat fixed to the application patch and arranged spaced apart from the first fixing seat; a flexible hook arranged on the second fixing seat, the flexible hook being capable of hooking with the arch bridge.

[0010] Further, the flexible hook is of flexible material, which, after deformation, passes through the arch bridge and recovers shape to be hooked on the arch bridge.

[0011] Further, the plurality of zipper assemblies are arranged in pairs with a cut as a center of symmetry.

[0012] Further, each of the zipper assemblies comprises a strap head and a tooth belt fixed to the application patch; a sawtooth is arranged on the inner wall of the channel of the strap head, and a sawtooth is arranged on the surface of the tooth belt and cooperates with the sawtooth; In the two zipper assemblies arranged in pairs, the tooth belt of one zipper assembly passes through the strap head of the other zipper assembly, and one-way locking is realized through cooperation of the sawtooth.

[0013] Further, the plurality of zipper assemblies cover and compress the plurality of buckles after being pulled tight.

[0014] Compared with the prior art, the present application has the following beneficial effects: 1. The present application realizes phased closing through the double-closing system of buckles and zipper assemblies. The skin is preliminarily gathered through the buckles, and then is strongly closed through the zipper assemblies, so that the operation process is more gentle, and the closing effect is more firm.

[0015] 2. Through the structural design of the flexible hook in the buckle, the flexible hook can deform first and then pass through the arch bridge when hooking, so that the skin is not violently pulled at the moment of closing, and the discomfort of the patient is greatly reduced.

[0016] 3. Through the arrangement of the zipper assemblies in pairs and symmetrically, and the one-way locking structure of the strap head and the tooth belt, the skin around the cut is uniformly pulled from multiple directions to the center, and a persistent and firm closed state is maintained.

[0017] 4. Through the arrangement of the zipper assemblies on the periphery of the buckles, the zipper assemblies can cover and compress the buckles in the inner ring after being pulled tight, realizing the effect of cooperative fixation, and effectively preventing the buckles of flexible material from being unhooked.

[0018] 5、Through setting the bandage, the whole patch is stably fixed on the neck of the patient, and the surrounding pressure of the bandage also helps the close combination of the patch and the skin. BRIEF DESCRIPTION OF DRAWINGS

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] Please refer to Figures 1 to 11 The present application provides a tracheostomy incision dressing after extubation. As shown in Figure 1 The dressing includes a dressing sheet 1 and a bandage 2 connected thereto. The dressing sheet 1 is the base of the entire device, which covers and adheres to the incision on the neck of the patient during use. The dressing sheet 1 itself has an adhesive bottom layer for adhesion and fixation. Specifically, the adhesive bottom layer is provided on the periphery of the dressing sheet 1 for adhesion to the skin around the incision, while the central area of the dressing sheet 1 corresponding to the incision is not provided with an adhesive layer to avoid sticking to the wound.

[0026] The bandage 2 is used to fix the entire dressing on the neck of the patient. In one embodiment, as Figure 1As shown, one end of the bandage 2 is connected to one side of the patch 1. Near the end of the bandage 2 connected to the patch 1, a loop 201 is provided. The other free end of the bandage 2 is provided with a first adhesive portion 202 and a second adhesive portion 203. The first adhesive portion 202 is located at the end of the bandage 2, and the second adhesive portion 203 is located next to the first adhesive portion 202. The loop 201, the first adhesive portion 202, and the second adhesive portion 203 are all provided on the side of the bandage 2 that does not contact the skin. In use, the bandage 2 is wrapped around the neck of the patient, with the free end of the bandage 2 passing through the loop 201, and only the first adhesive portion 202 passing through the loop 201. After passing through the loop 201, the first adhesive portion 202 is pulled in the opposite direction and folded over, so that it is fixed to the second adhesive portion 203. This structure not only fixes the patch, but also exerts pressure on the patch 1 through the wrapped bandage 2, so that the patch 1 is more tightly attached.

[0027] As shown in Figure 2 and Figure 3 , a plurality of clamps 101 are provided on the patch 1 around the center of the incision. These clamps 101 are preferably arranged in a circular array at equal intervals. The clamps 101 are used to preliminarily and gently gather the skin around the incision. Please refer to Figure 4 and Figure 5 , which show the structure of the clamps 101 in an open state. Each clamp 101 includes a first fixed seat 1011, an arch bridge portion 1012, a second fixed seat 1013, and a flexible hook 1014. The first fixed seat 1011 and the second fixed seat 1013 are both fixed to the surface of the patch 1 by adhesion or the like, and are parallel to and spaced apart from each other, serving as mounting platforms. The arch bridge portion 1012 is provided on the first fixed seat 1011 and protrudes outward in an arch shape. The flexible hook 1014 is provided on the second fixed seat 1013.

[0028] The structure of the flexible hook 1014 is the key to achieving gentle gathering. The flexible hook 1014 is made of a flexible material. Before assembly, as shown in Figure 5 , there is a gap between the flexible hook 1014 and the arch bridge portion 1012, and the underlying skin is in a flat state. When assembling, the operator can first change the curved shape of the flexible hook 1014, for example, straighten it, so that it can easily pass through the arch bridge portion 1012. After the flexible hook 1014 passes through the arch bridge portion 1012, it is pulled again and reshaped into a hook shape, so as to be hooked on the arch bridge portion 1012. Figure 6 、 7 , 8 shows the state of the clamps 101 after hooking and closing. In this way, during the hooking assembly process, the skin is gradually gathered, rather than instantaneously deformed, which reduces the pain and discomfort of the patient. When all the clamps 101 are hooked, the skin around the incision is effectively gathered.

[0029] As Figure 2 shown, on the periphery of the plurality of buckles 101, the patch 1 is also provided with a plurality of zipper assemblies 102. These zipper assemblies 102 are also preferably arranged in a ring array, for the final, strong closure of the incision. These zipper assemblies 102 are arranged in pairs, symmetrically centered on the incision. Please refer to Figure 11 , showing the perspective structure of a pair of zipper assemblies 102. Each zipper assembly 102 includes a strap head 1021 and a toothed belt 1022. The inside of the strap head 1021 is provided with a channel, and the inner wall of the channel is sawtoothed. One side of the toothed belt 1022 is provided with sawteeth along its length direction, which are matched with the sawteeth of the strap head 1021. The strap head 1021 and the toothed belt 1022 are both fixed on the patch 1.

[0030] In use, for a pair of two zipper assemblies (for example, A and B), the toothed belt 1022 of the A assembly penetrates the strap head 1021 of the B assembly, and the toothed belt 1022 of the B assembly correspondingly penetrates the strap head 1021 of the A assembly. As Figure 9 shown, the initial state of the plurality of zipper assemblies 102 before use is shown. When the toothed belts 1022 of the pairs are both penetrated (this is the state of being penetrated but not tightened), the operator only needs to synchronously pull the penetration ends of the two toothed belts 1022 in opposite directions, so as to strongly gather the skin between the two zipper assemblies 102 through the one-way locking action of the sawteeth. As Figure 10 shown, this is the state after tightening. After the same operation is performed on all pairs of zipper assemblies 102 in turn, the skin around the incision can be gathered towards the center of the incision until the incision is completely closed. Due to the cooperation of the sawtooth surfaces on the strap head 1021 and the toothed belt 1022, the tightening will not reset. After that, the excess toothed belt 1022 from the strap head 1021 can be cut off.

[0031] The technical solution of the present application also includes the cooperation between the buckle 101 and the zipper assembly 102. As Figure 2 shown, the zipper assembly 102 is arranged on the periphery of the buckle 101. It should be noted that, Figure 2The buckle 101 is drawn with dotted lines in the figure, which means that the buckle 101 will be covered by the zipper assembly 102 when the zipper assembly 102 is set and pulled tight, and the buckle 101 will be hidden at this time. The buckle 101 and the zipper assembly 102 are drawn with dotted lines in the figure to clearly show the inner and outer position relationship between the buckle 101 and the zipper assembly 102. When the zipper assembly 102 is pulled tight, the base or the tooth belt of the zipper assembly 102 will cover and press on the inner ring of the buckle 101. This pressing force provides an additional fixation for the flexible hook 1014, so that the flexible hook 1014 is less likely to be unhooked due to external extrusion after being hooked with the arch bridge part 1012. At the same time, the outermost strap 2 will also exert pressure on the entire patch 1 after being wrapped and fixed. This multiple action makes the fixation of the buckle 101 very stable. In summary, the present application realizes the preliminary gathering of the skin around the incision through the plurality of buckles 101, and realizes the complete closure of the incision through the plurality of pairs of zipper assemblies 102. The cooperation of each assembly makes the incision be stably gathered and not exposed again, which is beneficial to the healing and recovery of the incision.

[0032] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited to this. Any changes or replacements that can be easily thought of by those skilled in the art within the technical scope disclosed by the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
