Abstract
Description
Technical Field
[0001] This application relates to the field of pressure ulcer prevention pads for drainage tubes, and more particularly to a pressure ulcer prevention pad for drainage tubes. Background Technology
[0002] In the field of healthcare, patients with long-term drainage tubes are often at high risk of developing pressure ulcers, especially in bony prominences such as the back, sacrum, and lumbar region. Pressure ulcers are caused by prolonged, continuous pressure, leading to ischemia and hypoxia in the skin and underlying tissues. This not only causes significant pain for patients but can also lead to infection, prolong wound healing time, and increase medical costs. The presence of drainage tubes, particularly in patients requiring drainage in the back, further increases local pressure on the skin and tissues, making these areas more prone to pressure ulcers.
[0003] Currently, healthcare professionals employ various measures to prevent pressure ulcers, including regularly changing patient positions and using pressure-relieving pads and dressings. However, for drainage tubes used in the lumbar and back areas, which are typically long and require shaping for adjustment, existing pressure-relieving pads and dressings are difficult to adjust in size and cannot perfectly fit the shape and position of the drainage tube. This results in inadequate protection or patient discomfort, impacting the effectiveness of pressure ulcer prevention. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide an anti-pressure ulcer pad for drainage tubes, which aims to solve the problem that existing drainage tubes are prone to causing pressure ulcers.
[0005] The technical solution adopted by this application to solve the technical problem is as follows: a pressure relief pad for a drainage tube, comprising: a plurality of pressure relief pad bodies, wherein the plurality of pressure relief pad bodies are arranged along the length direction and are connected to each other through toothed portions, wherein the toothed portions are spaced apart along the width direction;
[0006] The pressure ulcer pad body includes: a dressing layer, the dressing layer being used to adhere to the patient's skin;
[0007] A pressure-equalizing layer is disposed on the dressing layer;
[0008] A limiting groove is provided on the surface of the pressure equalization layer away from the dressing layer, and the limiting groove is provided along the length direction. The limiting groove is used to place a drainage tube.
[0009] A binding strap is provided on the uniform pressure layer. The binding strap is used to form an annular structure with the limiting through groove and is sleeved on the drainage pipe to fix the drainage pipe.
[0010] Furthermore, the length of the limiting groove in the longitudinal direction is not greater than the length of the limiting groove in the width direction.
[0011] Furthermore, the limiting groove is an arc groove.
[0012] Furthermore, the depth of the limiting groove is greater than the outer diameter of the drainage pipe.
[0013] Furthermore, the hardness of the uniform pressing layer is not less than the hardness of the drainage tube.
[0014] Furthermore, the restraint strap is disposed within the limiting through groove, and the restraint strap does not protrude from the limiting through groove.
[0015] Furthermore, the restraint strap includes two connecting straps, one end of each connecting strap being disposed on the opposite sidewalls of the limiting through groove;
[0016] The adhesive portion is respectively disposed at one end of the two connecting strips away from the limiting groove, and the two connecting strips are detachably connected through the adhesive portion.
[0017] Furthermore, the pressure ulcer prevention pad also includes a release layer, wherein the surface of the dressing layer facing away from the limiting groove is an adhesive surface, and the release layer is disposed on the adhesive surface.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0031] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.
[0032] This utility model provides, for example Figures 1 to 4 The illustration shows an anti-pressure sore pad for a drainage tube, designed to address the shortcomings of existing drainage tubes that easily cause pressure sores.
[0033] The pressure-resistant pad for this drainage tube mainly includes: several pressure-resistant pad bodies 100, which are arranged along the length direction a and connected by perforated portions 200, which are spaced apart along the width direction b. Each pressure-resistant pad body 100 includes: a dressing layer 110, a pressure-equalizing layer 120, and a restraint strap 140. The dressing layer 110 is attached to the patient's skin, the pressure-equalizing layer 120 is disposed on the dressing layer 110, the restraint strap 140 is disposed on the pressure-equalizing layer 120, and a limiting groove 130 is provided on the pressure-equalizing layer 120.
[0034] Specifically, by setting perforated portions 200 (such as holes punched between stamps in a sheet of stamps for easy tearing), several pressure ulcer pad bodies 100 can be easily separated completely or partially. When two adjacent pressure ulcer pad bodies 100 are completely separated, they can be attached to different parts of the patient's skin and can be set arbitrarily with the drainage tube. When two adjacent pressure ulcer pad bodies 100 are partially separated, the limiting grooves 130 on the two pressure ulcer pad bodies 100 can be oriented in different directions, which can well cope with curved drainage tubes.
[0035] A limiting groove 130 is disposed on the surface of the uniform pressure layer 120 facing away from the dressing layer 110, and the limiting groove 130 is disposed along the length direction a. The limiting groove 130 is used to place the drainage tube. A binding strap 140 is used to form a ring structure with the limiting groove 130 and is sleeved on the drainage tube to fix the drainage tube.
[0036] In practical use, the drainage tube can first be inserted into several limiting slots 130, and then fixed in place by the restraint straps 140. During this process, several pressure ulcer pad bodies 100 can be separated as needed through the perforated portions 200, or adjacent pressure ulcer pad bodies 100 can be bent through the perforated portions 200 to adjust their positions, thus placing them in optimal adhesion positions. Finally, the pressure ulcer pad bodies 100 are adhered to the patient's skin. It should be noted that the perforated portions 200 allow the pressure ulcer pads to be arranged in an S-shape or U-shape, achieving a perfect fit with the shape and position of the drainage tube. Figure 4 As shown, the pressure ulcer pad is arranged in a U-shape. The dressing layer 110 is torn open at the perforated portion 200 at one end in the centrifugal direction, and the perforated portions 200 at the centripetal direction of the dressing layer 110 are connected to form a folded portion 111. The folded portion 111 allows the orientation of the limiting grooves 130 of two adjacent pressure ulcer pad bodies 100 to be changed, thereby allowing it to be shaped as needed to fit a drainage tube. When the pressure ulcer pad is arranged in an S-shape or a U-shape, the dressing layer 110 is flush with the surface facing the skin and protrudes away from the surface of the skin to form the folded portion 111.
[0037] Currently, healthcare professionals employ various measures to prevent pressure ulcers, including regularly changing patient positions and using pressure-relieving pads and dressings. However, for drainage tubes used in the lumbar and back areas, which are typically long and require shaping for adjustment, existing pressure-relieving pads and dressings are difficult to adjust in size and cannot perfectly fit the shape and position of the drainage tube. This results in inadequate protection or patient discomfort, impacting the effectiveness of pressure ulcer prevention.
[0038] This invention uses several pressure ulcer prevention pad bodies 100 to allow the drainage tube to be placed in the limiting groove 130 for fixation and then adhered to the skin through the dressing layer 110, thereby increasing the contact area between the drainage tube and the skin and reducing the probability of pressure ulcers. At the same time, since several pressure ulcer prevention pad bodies 100 are connected through the toothed part 200, medical staff can partially or completely separate adjacent pressure ulcer prevention pad bodies 100 during use to shape the pressure ulcer prevention pad and achieve a perfect fit with the shape and position of the drainage tube.
[0039] In some embodiments, such as Figure 1 As shown, the length of the limiting through groove 130 in the length direction a is not greater than the length of the limiting through groove 130 in the width direction b.
[0040] Specifically, this structure allows for a greater curvature of the two adjacent pressure ulcer pad bodies 100, making them more adaptable to various situations.
[0041] In some embodiments, such as Figure 1 , Figure 2 As shown, the limiting groove 130 is an arc groove.
[0042] Specifically, by setting the limiting groove 130 as an arc groove, the contact area between the limiting groove 130 and the drainage tube can be increased, thus avoiding damage to the drainage tube; at the same time, the pressure on the drainage tube can be more evenly distributed to the limiting groove 130, thereby improving the effect of preventing pressure sores.
[0043] In some embodiments, the depth of the limiting groove 130 is greater than the outer diameter of the drain pipe.
[0044] Specifically, the above settings ensure that the drainage tube does not protrude from the limiting groove 130. The patient can contact the bed through the pressure equalization layer 120 without pressing on the drainage tube, which will not easily affect the drainage effect. At the same time, it can also increase the contact area between the patient and the bed, better disperse the pressure, and improve the effect of preventing pressure ulcers.
[0045] In some embodiments, the hardness of the uniform pressing layer 120 is not less than the hardness of the drainage tube.
[0046] Specifically, if the hardness of the equalizing layer 120 is less than that of the drainage tube, the equalizing layer 120 will deform under pressure, which may cause the drainage tube to bulge out of the limiting groove 130, resulting in the drainage tube being compressed and thus affecting the drainage effect.
[0047] In some embodiments, such as Figure 1 , Figure 2 As shown, the restraint strap 140 is disposed within the limiting through groove 130, and the restraint strap 140 does not protrude from the limiting through groove 130.
[0048] With the above configuration, the restraint strap 140 does not protrude from the limiting groove 130, preventing the patient from contacting the bed through the restraint strap 140. This increases the contact area between the patient and the bed, better dispersing pressure and improving the prevention of pressure ulcers. It should be noted that "the restraint strap 140 does not protrude from the limiting groove 130" means that when the restraint strap 140 and the limiting groove 130 form a ring structure and are fitted onto the drainage tube, the restraint strap 140 does not protrude from the limiting groove 130.
[0049] In some embodiments, such as Figure 1 , Figure 2 As shown, the restraint strap 140 includes two connecting straps 141, one end of each connecting strap 141 being disposed on opposite sidewalls of the limiting through groove 130.
[0050] An adhesive portion 142 is provided at one end of each of the two connecting strips 141 away from the limiting groove 130, and the two connecting strips 141 are detachably connected by the adhesive portion 142. The adhesive portion 142 is preferably a Velcro strap.
[0051] In some embodiments, such as Figures 1 to 3 As shown, the pressure ulcer pad also includes: a release layer 150, the surface of the dressing layer 110 facing away from the limiting groove 130 is an adhesive surface, and the release layer 150 is disposed on the adhesive surface.
[0052] In actual use, after medical staff have adjusted several pressure ulcer pads 100 to the best pasting position, they can peel off the release layer 150 on each pressure ulcer pad 100 and stick it to the patient's skin, which makes it easier to adjust the pasting position of the pressure ulcer pad 100.
[0053] In some embodiments, such as Figures 1 to 3 As shown, the release layer 150 includes a release portion 151, which covers the adhesive surface of the dressing layer 110;
[0054] Separation section 152 is connected to release section 151.
[0055] In actual use, medical staff can pinch the separation part 152 and pull it to facilitate the separation of the release part 151 from the adhesive surface.
[0056] In some embodiments, such as Figures 1 to 3 As shown, the separation portion 152 is provided at one end of the release portion 151 in the width direction b.
[0057] Specifically, through the above-mentioned arrangement, even after several pressure ulcer pad bodies 100 are separated through the toothed portion 200, each pressure ulcer pad body 100 still has a portion of the separation portion 152, thus not affecting the function of the release portion 151.
[0058] In summary, this invention provides an anti-pressure ulcer pad for drainage tubes, comprising several anti-pressure ulcer pad bodies connected by perforated portions. Each anti-pressure ulcer pad body includes a dressing layer, a pressure-equalizing layer, and a binding strap. The pressure-equalizing layer is disposed on the dressing layer, and a limiting groove is disposed on the pressure-equalizing layer. The binding strap forms a ring structure with the limiting groove and is fitted onto the drainage tube to fix it in place. This invention, by using several anti-pressure ulcer pad bodies, allows the drainage tube to be placed within the limiting groove for fixation before being adhered to the skin through the dressing layer, increasing the contact area between the drainage tube and the skin to reduce the probability of pressure ulcers. Furthermore, because the several anti-pressure ulcer pad bodies are connected by perforated portions, medical personnel can partially or completely separate adjacent anti-pressure ulcer pad bodies during use to shape the pads and achieve a perfect fit to the shape and position of the drainage tube.
[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
