Description

Technical Field

[0001] The present application relates to the field of medical devices and more particularly to a tracheotomy tube fixing dressing. Background Art

[0002] With the continuous development of medical technology, tracheotomy has been widely used in clinical practice, playing an important role in the rescue and rehabilitation of critically ill patients. After the tracheotomy, the patient's tracheotomy is usually covered with a tracheotomy dressing, which not only absorbs blood and fluid from the incision and protects the incision from infection, but also can be used to fix the fixing seat of the tracheal tube, making it convenient to install it in the patient's throat (front neck area), alleviating the patient's pain.

[0003] In the prior art with patent number 202121660655.3, entitled a self-adhesive bidirectional fixing device suitable for tracheal tubes, the back of the device has a fixing mechanism that can fix the fixing seat of the tracheal tube on the patch. However, the skin near the human neck, especially the anterior neck area, is very soft and has less stiffness than the skin of other parts of the human body. The patch attached to the throat can easily move with the skin, resulting in unstable installation of the fixing seat of the tracheal tube, affecting the installation of the tracheal tube, or even falling off; and when the patch is installed under the fixing seat of the tracheal tube, in order to fix the fixing seat of the tracheal tube, tension will inevitably be generated between the patch and the fixing seat, coupled with the gravity of the fixing seat itself, which will inevitably produce a pulling force on the patch. This pulling force is applied to the softer throat skin, further resulting in the instability of the installation of the fixing seat of the tracheal tube, resulting in the need for medical staff to frequently adjust or replace the dressing, which brings inconvenience to medical staff and increases the distress of patients.

[0004] Therefore, the dressing structure for tracheal tubes in the prior art is relatively simple and cannot meet the current clinical needs. There is a need for a dressing that can be stably applied to the skin. Summary of the invention

[0005] In order to solve or at least partially solve the above technical problems, the present application provides a tracheotomy tube fixing dressing, comprising:

[0006] A dressing body having a first surface for applying to the skin, a second surface opposite to the first surface, and a through hole for passing a tracheal tube;

[0007] A fixing mechanism, arranged in pairs on both sides of the through hole, for applying a pulling force to the fixing seat of the tracheal cannula to fix the fixing seat to the second surface;

[0008] The reinforcing rib is arranged on the dressing body and at least partially extends in a direction forming an angle with the pulling direction. The reinforcing rib and the projection of the fixing mechanism on the surface of the dressing body intersect.

[0009] Optionally, the tracheostomy tube fixation dressing may also include:

[0010] An anchor is arranged at the intersection of the reinforcing rib and the fixing mechanism, and penetrates the dressing body to fix the reinforcing rib and the fixing mechanism.

[0011] Optionally, the fixing mechanism includes a fixing portion and a movable portion;

[0012] The fixing portion is connected to the second surface;

[0013] The movable portion extends from the fixed portion to the outside of the second surface so as to be connected to the fixed seat;

[0014] The anchor is disposed at a position of the fixed portion close to the movable portion.

[0015] Optionally, the anchoring member comprises:

[0016] A first buckle body abuts against the surface of the fixing portion;

[0017] A second buckle body abutting against the first surface;

[0018] A connecting rod, passing through the dressing body and connecting the first buckle body and the second buckle body;

[0019] The first buckle body and the second buckle body clamp the dressing body and the fixing part.

[0020] Optionally, the movable portion can pass through the fixing seat and then be folded and detachably connected to the fixing portion;

[0021] A clamping space is formed between the first buckle body and the folded movable portion, and the first buckle body has a preset thickness for narrowing the clamping space to clamp the fixing seat;

[0022] The first buckle body at least partially extends to the surface of the movable portion so as to abut against the movable portion after the movable portion is folded.

[0023] Optionally, the fixing portion extends in a direction away from the through hole, and an angle between the reinforcing rib and the fixing portion is 30-90 degrees.

[0024] Optionally, the length of the movable portion is greater than the length of the fixed portion, so that after the movable portion is folded and connected to the fixed portion, an end of the movable portion can extend beyond the fixed portion.

[0025] Optionally, the fixing portion extends in a direction away from the through hole, and is provided with cut marks arranged in sequence and at intervals along the extension direction, the opening direction of the cut marks forms an angle with the extension direction of the fixing portion, and the opening directions of adjacent cut marks are opposite.

[0026] Optionally, the dressing body comprises an adhesion area for adhering to the skin and an adsorption area for applying to the tracheotomy, and the adhesion area surrounds the periphery of the adsorption area;

[0027] The projections of the reinforcing rib and the fixing mechanism on the second surface intersect at the adsorption area, and the reinforcing rib extends from the adsorption area to the adhesion area.

[0028] Optionally, the adhesion area includes a plurality of adhesion sub-areas arranged in a circumferential direction of the adsorption area and extending to the outside of the adsorption area, and each of the adhesion sub-areas has at least one reinforcement rib.

[0029] The tracheostomy tube fixing dressing provided in the present application is provided with reinforcing ribs on the dressing body, and the reinforcing ribs extend along the surface of the dressing body to increase the strength of the tracheostomy tube fixing dressing. Importantly, the reinforcing ribs intersect with the projections of the fixing mechanism on the surface of the dressing body, and at least part of the reinforcing ribs extend in a direction forming an angle with the direction of the pulling force from the fixing seat received by the fixing mechanism, so that the pulling force borne by the fixing mechanism is dispersed to the reinforcing ribs, and then dispersed to different areas of the tracheostomy tube fixing dressing through the reinforcing ribs, thereby playing a buffering role, alleviating the local stress concentration of the tracheostomy tube fixing dressing when the tracheostomy tube fixing seat is fixed, thereby reducing the degree of deformation of the tracheostomy tube fixing dressing when it is attached to the patient's throat skin, ensuring the stability of the installation of the fixing seat, providing protection for the installation of the artificial airway, reducing the workload of medical personnel for frequent adjustments and replacements, and alleviating the pain of patients caused by unstable installation of the tracheostomy tube.

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0055] The technical solutions in the embodiments of the present application will be described in detail below in conjunction with the drawings in the embodiments of the present application.

[0056] Example 1

[0057] This embodiment provides a tracheotomy tube fixing dressing, which is applied to the incision after tracheotomy surgery. The tracheotomy tube fixing dressing is not only used as a dressing at the incision to prevent infection, but can also be used to fix the tracheal tube 50 to ensure stable installation of the tracheal tube 50.

[0058] like Figure 1-Figure 3 As shown, the tracheostomy tube fixing dressing of this embodiment includes a dressing body 10, one side of the dressing body 10 is a first surface, which is used to be applied to the skin, wherein the first surface includes an adhesive area 11 and an adsorption area 12, the adhesive area 11 adheres to the periphery of the tracheal surgical incision, and is used to fix the dressing body 10 near the patient's throat, the adsorption area 12 corresponds to the tracheal surgical incision, and is used to cover the tracheal surgical incision to prevent the surgical incision from being exposed to the outside and infected, and can absorb exudate and ensure the hygiene and cleanliness of the surgical incision.

[0059] The other side of the dressing body 10 is the second surface, that is, the back side of the dressing body 10. Preferably, Figure 5 As shown, the dressing body 10 has a back film layer 13, which is arranged on one side of the adhesion area 11 and the adsorption area 12 to connect the adhesion area 11 and the adsorption area 12 as a whole, so that the dressing body 10 has certain strength and toughness. The second surface is the surface of the back film layer 13 facing outward.

[0060] The dressing body 10 is also provided with a through hole 101, which penetrates the dressing body 10 so that the first surface and the second surface can be connected, and the through hole 101 is used to allow the tracheal tube 50 connected to the patient's trachea to pass through. The through hole 101 is provided in the adsorption area 12, and the adsorption area 12 needs to surround the through hole 101.

[0061] like Figure 2 and Figure 3 As shown, the dressing body 10 has a cut 102 extending from the edge of the dressing body 10 to the through hole 101 , and the cut 102 can form an opening of the through hole 101 , so as to facilitate the tracheal tube 50 to be placed into the through hole 101 along the cut 102 .

[0062] In clinical care, the dressing body 10 is put on the tracheal tube 50 along the incision 102 until the tracheal tube 50 falls into the through hole 101, and then the dressing body 10 is applied near the throat. The adsorption area 12 corresponds to and covers the tracheal surgical incision, protects the surgical incision, and surrounds the tracheal tube 50.

[0063] like Figure 1 and Figure 3 As shown, this embodiment further has a fixing mechanism 20, two fixing mechanisms 20 are respectively provided, and the two fixing mechanisms 20 are arranged in pairs on the second surfaces on both sides of the through hole 101. The fixing mechanism 20 is used to fix the fixing seat 60 of the tracheal tube 50.

[0064] like Figure 6As shown, the tracheal tube 50 needs to be fixed by a fixing seat 60 when it is installed in place. The fixing seat 60 has connecting holes on opposite sides, which correspond to two fixing mechanisms 20 respectively. Each fixing mechanism 20 passes through the corresponding connecting hole and is connected to the fixing seat 60. After the connection is completed, the two fixing mechanisms 20 arranged opposite to each other pull the fixing seat 60 from both sides respectively, so as to fix the fixing seat 60 on the second surface. The fixing seat 60 ensures that the tracheal tube 50 is not easy to loosen.

[0065] In this embodiment, the fixing seat 60 is placed on the surface of the dressing body 10 and is not directly connected to the dressing body 10. The two fixing mechanisms 20 fix the fixing seat 60 to the second surface by applying pulling forces to both sides of the fixing seat 60.

[0066] It can be imagined that, as mentioned above, the fixing mechanism 20 bears the force to fix the fixing seat 60, and the fixing mechanism 20 is arranged on the surface of the dressing body 10, and the dressing body 10 is fixed by adhering to the skin of the front part of the patient's neck. Since the skin of the neck is relatively soft and has many wrinkles, the dressing body 10 attached to the skin of the neck is easy to loosen. When the fixing mechanism 20 applies the pulling force of the supporting fixing seat 60 to the dressing body 10, the force of the dressing body 10 is concentrated near the fixing mechanism 20, and the dressing body 10 is more likely to loosen. Even under the pulling force of the fixing mechanism 20 acting on both sides, the dressing body 10 causes the skin of the patient's neck to be obviously deformed, resulting in the following phenomenon: Figure 7 As shown, the dressing body 10 is wrinkled toward the middle, which pulls the patient's throat and causes great discomfort to the patient. In addition, the dressing body 10 is loose and bulges outward, causing the fixing seat 60 to shift, which is not conducive to the stability of the fixing seat 60 and is easy to fall off. However, simply strengthening the hardness of the dressing body 10 will cause other problems, such as patient discomfort, poor adhesion, poor air permeability, etc., so this is not a problem that can be solved by strengthening the hardness of the dressing body 10.

[0067] Therefore, if Figure 1-Figure 3 As shown, in this embodiment, reinforcing ribs 30 are further provided on the dressing body 10, and each fixing mechanism 20 corresponds to at least one reinforcing rib 30, wherein each reinforcing rib 30 at least partially extends in a direction forming an angle with the above-mentioned pulling direction, and the projections of the reinforcing ribs 30 and the fixing mechanism 20 on the surface of the dressing body 10 intersect.

[0068] That is to say, the extension direction of the reinforcing rib 30 is different from the pulling direction of the fixing mechanism 20, or at least the extension direction of a part of the reinforcing rib 30 is different from the pulling direction of the fixing mechanism 20, and the extension path of the reinforcing rib 30 passes through the fixing mechanism 20. It can be understood that when the reinforcing rib 30 is arranged on the second surface of the dressing body 10, the reinforcing rib 30 and the fixing mechanism 20 intersect or stagger, and the two are directly connected; when the reinforcing rib 30 is arranged inside the dressing body 10, or on the first surface, the reinforcing rib 30 and the fixing mechanism 20 are not in direct contact, but on the projection surface of the dressing body 10, the two intersect or stagger, or the two are very close, so as to ensure that when the fixing mechanism 20 is subjected to tension, the tension will act on the reinforcing rib 30.

[0069] You can refer to Figure 8 Such a design enables the reinforcing rib 30 to be coupled with the fixing mechanism 20 on the dressing body 10, and the tensile force borne by the fixing mechanism 20 is dispersed to the reinforcing rib 30, and then dispersed to different areas of the dressing body 10 through the reinforcing rib 30, thereby playing a buffering role and alleviating the local stress concentration of the dressing body 10 when fixing the fixing seat 60 of the tracheal tube 50, thereby reducing the deformation degree of the dressing body 10 when it is attached to the patient's throat skin, and ensuring the stability of the installation of the fixing seat 60.

[0070] Fig.13 As for the clinical application of the tracheostomy tube fixing dressing of the present application, it can be seen that when the tracheostomy tube fixing dressing is applied to the patient's throat, it does not affect the patient's application feeling, is not easy to deform or wrinkle, has a certain anti-disturbance, and is conducive to the installation and fixation of the fixing seat 60.

[0071] The tracheostomy tube fixing dressing provided in this embodiment can provide a guarantee for the installation of an artificial airway, reduce the workload of medical personnel in frequently adjusting and replacing the tracheostomy tube, and alleviate the pain of patients caused by the unstable installation of the tracheal tube 50.

[0072] In some embodiments, the back film layer 13 is made of polyurethane, the adhesive area 11 is a soft silicone adhesive layer attached to the surface of the back film layer 13 , and the adsorption area 12 can be a polyurethane foam layer attached to the surface of the back film layer 13 .

[0073] Since the polyurethane foam will swell and scatter when it comes into contact with water, the adsorption area 12 is in contact with the exudate of the patient's incision over a large area, and it is easy to swell and deform, affecting the coverage of the incision and the adsorption effect. In one embodiment, the reinforcing rib 30 is in direct contact with the adsorption area 12, so that the reinforcing rib 30 can play a pulling role, to a certain extent limit the expansion and deformation of the polyurethane foam when it comes into contact with water, and prevent the foam in the adsorption area 12 from scattering.

[0074] Preferably, the reinforcing ribs 30 can be arranged on the outer surface of the adsorption area 12, that is, the reinforcing ribs 30 are closer to the skin than the adsorption area 12, the soft silicone adhesive layer is arranged on the reinforcing ribs 30, and the reinforcing ribs 30 are located at the two side edges of the adsorption area 12, so as not to affect the adsorption effect of the adsorption area 12 on the incision. In this way, the edge of the adsorption area 12 has a certain degree of adhesion, ensuring that the adsorption area 12 is attached to the skin and improving stability, and the reinforcing ribs 30 can further pull the adsorption area 12 to limit the expansion and deformation of the adsorption area 12 when it encounters water.

[0075] Example 2

[0076] This embodiment provides a tracheotomy tube fixing dressing. This embodiment is based on Embodiment 1 and further improves the connection relationship between the reinforcing rib 30 and the fixing mechanism 20.

[0077] In this embodiment, see Figure 1 and Figure 4 As shown, an anchor 40 is provided at the intersection of the reinforcing rib 30 and the fixing mechanism 20 , and the anchor 40 penetrates the dressing body 10 to fix the reinforcing rib 30 and the fixing mechanism 20 together.

[0078] The anchor 40 directly connects the reinforcing rib 30 with the fixing mechanism 20, thereby enhancing the coupling strength between the reinforcing rib 30 and the fixing mechanism 20. The tension exerted on the fixing mechanism 20 acts on the reinforcing rib 30 through the anchor 40, thereby reducing the direct force or transmission force on the dressing body 10. In this way, the tracheotomy tube fixing dressing can withstand greater tension and will not be easily deformed by the tension. The dressing body 10 is also not easily damaged due to excessive local force.

[0079] In this embodiment, the reinforcing rib 30 and the fixing mechanism 20 are formed into a whole through the anchor 40, which can simultaneously withstand external tension and the movement of the tracheostomy tube fixing dressing caused by the patient's laryngeal movement, so that the overall stiffness of the tracheostomy tube fixing dressing is increased, but it will not be too hard to cause discomfort to the patient and can adapt well to the throat skin.

[0080] In one embodiment, Figure 4 As shown, the fixing mechanism 20 includes a fixing portion 21 and a movable portion 22. The fixing portion 21 is connected to the second surface, and the movable portion 22 extends from the fixing portion 21 to the outside of the second surface for connecting to the fixing seat 60. The anchor 40 is arranged at a position of the fixing portion 21 close to the movable portion 22.

[0081] One end of the movable part 22 is connected to the fixed part 21, and the other end is freely movable and used to connect with the fixing seat 60. The anchor 40 can firmly fix the fixed part 21 on the second surface. When the movable part 22 is subjected to tension on the fixed part 21, the anchor 40 can stabilize the fixed part 21 and disperse the tension to the reinforcing rib 30 through the anchor 40, thereby playing a buffering role and achieving the advantages mentioned above.

[0082] In one embodiment, Figure 5 As shown, the anchor 40 includes a first buckle body 41, a second buckle body 42 and a connecting rod 43. The first buckle body 41 abuts against the surface of the fixing portion 21, the second buckle body 42 abuts against the first surface, and the connecting rod 43 penetrates the dressing body 10 and connects the first buckle body 41 and the second buckle body 42. This structural design allows the first buckle body 41 and the second buckle body 42 to clamp the dressing body 10 and the fixing portion 21.

[0083] In this way, the movable part 22 is subjected to tensile force and transmitted to the anchor 40, and the first buckle body 41 and the second buckle body 42 are subjected to force at the same time, and the tensile force is dispersed to the back film layer 13, the reinforcing ribs 30 and the adsorption area 12, and is also dispersed to the bottom of the dressing body 10. The second buckle body 42 supports the dressing body 10 from the bottom, thereby enhancing the local force-bearing capacity of the dressing body 10.

[0084] The first buckle body 41 and the second buckle body 42 of this embodiment have a certain area so as to disperse the pulling force over a larger range and avoid local stress concentration on the dressing body 10; and the first buckle body 41 and the second buckle body 42 can better clamp the dressing body 10 and enhance the strength of the dressing body 10.

[0085] like Figure 5 As shown, in one embodiment, the movable part 22 can pass through the fixed seat 60 and then be folded to be detachably connected to the fixed part 21. Specifically, a first connecting buckle 211 is provided on the surface of the fixed part 21, and a second connecting buckle 221 is provided on the surface of the movable part 22. After the movable part 22 is folded, it corresponds to the fixed part 21, and the two are detachably connected through the first connecting buckle 211 and the second connecting buckle 221.

[0086] Preferably, the first connecting buckle 211 and the second connecting buckle 221 may be structures such as felt or nylon hook and loop, and this embodiment is not intended to be the sole limitation.

[0087] In this embodiment, a clamping space 201 is formed between the first buckle body 41 and the folded movable portion 22 , and the connecting arm of the fixing seat 60 is locked in the clamping space 201 to prevent the fixing seat 60 from falling off.

[0088] It is worth mentioning that the first buckle body 41 and the second buckle body 42 of the present embodiment not only play the role of clamping the dressing body 10, but the first buckle body 41 also has a preset thickness. The thickness of the first buckle body 41 is used to limit the clamping space 201, so that the first buckle body 41 and the movable part 22 can clamp the fixing seat 60 to prevent the fixing seat 60 from shaking after installation, thereby improving the stability of the fixing seat 60.

[0089] In order to further improve the stability of the fixed seat 60, a first anti-slip structure 222 is provided on the surface of the movable part 22, and a second anti-slip structure 411 is provided on the surface of the first buckle body 41. The first anti-slip structure 222 and the second anti-slip structure 411 respectively contact the upper and lower surfaces of the connecting arm of the fixed seat 60 to prevent the fixed seat 60 from shaking in the clamping space 201.

[0090] Of course, in order to simplify the structure, the first anti-slip structure 222 can also be the first connecting buckle 211, such as felt, which contacts the fixing seat 60 to play an anti-slip role, and the second anti-slip structure 411 can be a protrusion on the surface of the first buckle body 41, ensuring that the surface of the first buckle body 41 is not smooth.

[0091] As a further improvement, in one embodiment, the first buckle body 41 at least partially extends to the surface of the movable portion 22, so as to abut against the movable portion 22 after the movable portion 22 is folded. Specifically, the movable portion 22 is connected to the fixed portion 21 via a connecting portion 23, and the connecting portion 23 enables the movable portion 22 to be flipped relative to the fixed portion 21. Preferably, the connecting portion 23 can be a fold. In this embodiment, at least part of the first buckle body 41 is beyond the connecting portion 23, that is, Figure 5 As shown, the connecting portion 23 is located directly below the first buckle body 41 and does not extend beyond the first buckle body 41. In this way, when the movable portion 22 is bent upward, the first buckle body 41 at least presses a portion of the movable portion 22, and a portion of the tension applied to the movable portion 22 is transferred to the first buckle body 41, thereby avoiding excessive tension directly acting on the fixed portion 21, thereby giving full play to the advantages of the anchor 40 as described above.

[0092] In one embodiment, the movable portion 22 is softer in material than the fixed portion 21 to facilitate passing through the connection hole of the fixing seat 60 and folding of the movable portion 22. However, it should not be too soft, which makes it difficult to pass through the connection hole of the fixing seat 60, inconvenient for medical staff to operate, and unable to provide a good stable restriction on the fixing seat 60.

[0093] In one embodiment, the length of the movable portion 22 is greater than that of the fixed portion 21, so that after the movable portion 22 is folded and connected to the fixed portion 21, the end of the movable portion 22 can extend beyond the fixed portion 21, so that medical personnel can untie the movable portion 22 and replace the tracheotomy tube fixing dressing.

[0094] See also Figure 3 In this embodiment, the fixing portion 21 extends in a direction away from the through hole 101 , and the angle between the reinforcing rib 30 and the fixing portion 21 is 30-90 degrees, which facilitates the transmission of the tension of the fixing mechanism 20 to most areas of the dressing body 10 .

[0095] Preferably, the included angle between the reinforcing rib 30 and the fixing portion 21 is 90 degrees, the fixing portion 21 extends along the length direction of the dressing body 10 , and the reinforcing rib 30 extends along the width direction of the dressing body 10 .

[0096] like Figure 7 As shown, when the reinforcing ribs 30 are not provided, the pulling force F1 on the dressing body 10 is concentrated on the fixing portion 21. Since the fixing portion 21 is arranged in the middle of the dressing body 10, the edge of the dressing body 10 shrinks toward the middle, the deformation is more obvious, and wrinkles appear, which pulls the patient's throat skin, causing pain to the patient and also causing instability of the fixing seat 60.

[0097] When a reinforcing rib 30 perpendicular to the fixing portion 21 is provided, such as Figure 8 As shown, the tension F2 exists not only near the fixing portion 21, but also near the reinforcing rib 30. In this way, the tension near the fixing portion 21 is obviously dispersed, F2 must be smaller than F1, and the local tension of the anchor 40 is also dispersed by the reinforcing rib 30. The lateral tension of the dressing body 10 is effectively alleviated, which reduces the patient's pain and ensures the stable installation of the fixing seat 60.

[0098] In one embodiment, the reinforcing rib 30 has a certain width, which is greater than the width covered by the anchor 40 to ensure that the force of the anchor 40 is well dispersed to the reinforcing rib 30 .

[0099] Of course, the angle between the reinforcing rib 30 and the fixing portion 21 is not limited to 30-90 degrees, and even the reinforcing rib 30 is not limited to a straight line. The reinforcing rib 30 can also be an arc, a curved line, or a circle acting on the dressing body 10, so the structure of the reinforcing rib 30 is not limited to a single limit.

[0100] Since the fixed part 21 needs to bear a certain pulling force and needs to ensure the connection strength with the movable part 22, the fixed part 21 needs to have a certain hardness. However, it is also necessary to ensure that the fixed part 21 can follow the dressing body 10 to ensure the patient's usage experience. Therefore, the flexibility of the fixed part 21 also has certain requirements.

[0101] like Fig. 9 As shown, in one embodiment, the fixing portion 21 extends in a direction away from the through hole 101, and the fixing portion 21 is provided with cut marks 212 arranged in sequence and spaced apart along the extension direction, the opening direction of the cut marks 212 forms an angle with the extension direction of the fixing portion 21, and the opening directions of adjacent cut marks 212 are opposite.

[0102] In this way, while ensuring that the fixing portion 21 is continuous in its extension direction, the fixing portion 21 has a certain flexibility and can bend with the dressing body 10 to adapt to the patient's throat skin; this design also has another advantage. The cut mark 212 makes the fixing portion 21 have a certain extensibility in its extension direction, which plays a buffering role against the pulling force.

[0103] Example 3

[0104] This embodiment provides another form of tracheotomy tube fixing dressing based on Embodiment 2.

[0105] like Fig.10 As shown, the adhesion area 11 of the dressing body 10 is surrounded by the periphery of the adsorption area 12, the projections of the reinforcing ribs 30 and the fixing mechanism 20 on the second surface intersect at the adsorption area 12, and the reinforcing ribs 30 extend from the adsorption area 12 to the adhesion area 11 to improve the strength of the entire tracheotomy tube fixing dressing.

[0106] Several notches are respectively arranged at the edge of the adhesion area 11 of the dressing body 10. Preferably, the notches are respectively arranged at the upper and lower sides and the left and right sides of the dressing body 10, corresponding to the upper and lower and left and right areas of the patient's throat, respectively, so that the dressing body 10 is similar to a butterfly shape.

[0107] See also Fig.12 , the figure shows a butterfly-shaped tracheostomy tube fixing dressing in one embodiment of the present application, which is in an unopened package. It can be seen that the movable portion 22 is in the same plane as the fixed portion 21 when not folded, which is convenient for packaging, and the anchor 40 is on the edge of the fixed portion 21 close to the movable portion 22.

[0108] Fig.14 The butterfly-shaped tracheostomy tube fixing dressing is used clinically. It can be seen that the butterfly-shaped tracheostomy tube fixing dressing can contact the patient's throat with the smallest possible area while ensuring the stable installation of the fixing seat 60, thereby reducing the discomfort caused by the application to the patient.

[0109] The notch divides the adhesion area 11 into a plurality of adhesion sub-areas 111. The plurality of adhesion sub-areas 111 are arranged in the circumferential direction of the adsorption area 12 and extend to the outside of the adsorption area 12. The notch can leave a certain space for the throat area to avoid the dressing body 10 being too large to affect the patient's feeling, and can also reduce the deformation and wrinkling of the middle area of ​​the dressing body 10.

[0110] In this embodiment, each adhesion sub-region 111 has at least one reinforcing rib 30, which extends from the adsorption area 12 to the edge of the adhesion sub-region 111 to disperse the tension to each adhesion sub-region 111, ensuring that the dressing body 10 is not deformed when applied to the skin.

[0111] In one embodiment, Fig.11 As shown, the reinforcing rib 30 forms an angle of about 45 degrees with the fixing portion 21, and the reinforcing rib 30 extends to the edge of the adhesion sub-area 111 with the maximum straight length, so that each adhesion sub-area 111 can evenly withstand the tensile force transmitted by the reinforcing rib 30, ensuring that the dressing body 10 is better adhered to the skin.

[0112] The shape of the dressing body 10 of this embodiment is not limited to the square or butterfly shape shown in the drawings, and can also be adaptively designed according to different groups of people, different body parts, and different patient body parameters. The shape of the dressing body 10 of this embodiment is not limited to the sole shape.

[0113] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
