Abstract
Description
Technical Field
[0001] This application relates to the field of medical care technology, and in particular to an adjustable support pad for preventing pressure sores. Background Technology
[0002] Pressure ulcers are a condition caused by prolonged pressure on local tissues, leading to persistent ischemia, hypoxia, and malnutrition, resulting in local tissue ulceration and ischemic necrosis. They are also known as bedsores or pressure sores and usually occur in the sacrum, bony prominences, or areas that come into contact with medical devices or other instruments. For patients who are bedridden for long periods or paralyzed and sit for extended periods, using pressure ulcer support pads is one of the important measures to prevent sacral pressure ulcers.
[0003] Most existing pressure ulcer support pads are designed by hollowing out areas prone to pressure ulcers to make room for the skin and prevent compression. While this can prevent pressure ulcers to some extent, it still has some shortcomings. Because different patients have different body shapes, weights, and pressure distribution on different parts of their bodies, and the support area of existing support pads is fixed, it is difficult to flexibly adjust them according to the specific needs of patients. This results in poor support for some patients, failing to effectively distribute pressure and actually increasing the risk of pressure ulcers.
[0004] Therefore, existing pressure-resistant pads with fixed support areas cannot meet the needs of dynamic adjustment. To address this issue, we propose an adjustable pressure-resistant pad with adjustable support area to prevent pressure sores. Utility Model Content
[0005] In view of the problems existing in the prior art, the purpose of this application is to solve the problem that the support area of the existing pressure ulcer support pad is fixed and cannot meet the individual differences and dynamic nursing needs of different patients. Compared with the prior art, this application provides a pressure ulcer support pad with an adjustable support area.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.
[0007] An adjustable support area pressure ulcer support pad includes a base pad for providing basic support; The middle area of the base pad is equipped with several annular airbags arranged in a concentric nested pattern. Several long airbags are provided on both sides of the annular airbags along the length direction of the base pad, and several short airbags are provided on both sides of the annular airbags along the width direction of the base pad. The annular airbag, long airbag, and short airbag are covered with a top pad for direct contact with the human body. The top pad and the bottom pad form a receiving space for enclosing the annular airbag, long airbag, and short airbag.
[0008] Furthermore, each of the aforementioned annular airbag, long airbag, and short airbag is independently equipped with an inflation port with a valve.
[0009] Furthermore, the bottom pad is made of a soft and elastic material, and the top pad is made of a soft and breathable fabric.
[0010] Furthermore, multiple straps are provided around the four edges of both the bottom pad and the top pad; The ends of the straps are equipped with matching buckles or Velcro, and the straps on the bottom pad correspond one-to-one with the straps on the top pad.
[0011] Furthermore, the upper surface of the base pad is provided with a plurality of annular grooves, long grooves and short grooves respectively adapted to the shapes of the annular airbag, long airbag and short airbag; The bottom of the annular airbag, long airbag, and short airbag are all fixedly connected with sub-hook and loop fasteners, and the bottom of the annular groove, long groove, and short groove are fixedly connected with female hook and loop fasteners corresponding to the positions of the sub-hook and loop fasteners.
[0012] Compared to existing technologies, the advantages of this application are: By installing several concentrically arranged ring-shaped airbags in the middle area of the base pad, the installation position of the ring-shaped airbags corresponds to the sacral position of the human body. People of different weights and body types can choose the number of ring-shaped airbags to adjust the support area according to their needs. Long airbags and short airbags are set around the ring-shaped airbags. Based on the patient's feedback and the actual support effect, the inflation volume of each airbag is gradually fine-tuned to achieve the best support and decompression effect.

[0015] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0016] This utility model provides an adjustable support area for preventing pressure sores. Please refer to [link / reference]. Figure 1-4 The pressure ulcer support pad is designed with multiple airbags combined for support, so that the support area can be adjusted according to the different needs of people with different body types and weights.
[0017] Specifically, this includes the base pad 1 used to provide basic support.
[0018] The middle area of the base pad 1 is equipped with several annular airbags 2 arranged in a nested pattern. Several long airbags 3 are installed on the base pad 1 on both sides of the annular airbags 2 along the length direction of the base pad 1. Several short airbags 4 are installed on the base pad 1 on both sides of the annular airbags 2 along the width direction of the base pad 1.
[0019] The annular airbag 2, the long airbag 3, and the short airbag 4 are covered with a top pad 5 for direct contact with the human body. The top pad 5 and the bottom pad 1 form a space for containing the annular airbag 2, the long airbag 3, and the short airbag 4.
[0020] The ring-shaped airbag 2 is installed at the sacral region of the human body.
[0021] Using this method, people of different weights and body types can adjust the support area by choosing the number of ring-shaped airbags 2 used according to their needs. The fatter or taller a person is, the larger the area of pressure sores on the sacrum will be. Therefore, it is necessary to reduce the number of ring-shaped airbags 2 used to reduce the support area. Conversely, the thinner a person is, the smaller the area of pressure sores on the sacrum will be. Therefore, it is necessary to increase the number of ring-shaped airbags 2 used to increase the support area, making the patient more comfortable when lying down.
[0022] The base pad 1 is made of a soft and elastic material, such as sponge, and the bottom of the base pad 1 is designed to be non-slip. The top pad 5 is made of a soft and breathable fabric. The top pad 5 is in direct contact with the human body. The use of a soft and breathable fabric can ensure good breathability of the patient's skin. In addition, ventilation holes can be set on the top pad 5 to improve breathability.
[0023] For ease of storage and use, each airbag needs to be able to inflate and deflate independently.
[0024] Specifically, each of the annular airbag 2, long airbag 3, and short airbag 4 is independently equipped with an inflation port 6 with a valve.
[0025] The nursing staff inflates the ring-shaped airbag 2, the long airbag 3, and the short airbag 4 by connecting to an external air source.
[0026] In this way, when it is necessary to reduce the support area of a certain area, the control valve of the corresponding airbag is opened to release air, the airbag contracts, and the contact area is reduced. During the adjustment process, the inflation volume of each airbag can be gradually fine-tuned according to the patient's feedback and the actual support effect to achieve the best support and decompression effect.
[0027] In addition, when the patient needs to change posture, such as from lying down to sitting, the air in one or more long air bladders 3 can be released to make them press down, which allows the support pad to be folded at a certain angle, so that it can also prevent pressure sores when the patient is sitting or leaning.
[0028] To facilitate the fixing of the top pad 5 and prevent the top pad 5 from shifting or deviating during use, the following preferred embodiments are provided: Multiple straps 7 are provided around the four edges of both the bottom pad 1 and the top pad 5; The ends of the straps 7 are equipped with matching buckles or Velcro, and the straps 7 on the bottom pad 1 correspond one-to-one with the straps 7 on the top pad 5.
[0029] The top pad 5 can be fixed to the bottom pad 1 by means of the strap 7. On the one hand, it can fix the top pad 5 to prevent it from shifting during use. On the other hand, it can also protect the annular airbag 2, the long airbag 3 and the short airbag 4 from being punctured by sharp objects.
[0030] Airbags may rupture during use due to external force or pressure from sharp objects. To maintain the support pad's good support function, the following preferred embodiments are provided: The upper surface of the base pad 1 is provided with several annular grooves 8, long grooves 9 and short grooves 10 that are respectively adapted to the shapes of the annular airbag 2, long airbag 3 and short airbag 4; The bottoms of the annular airbag 2, the long airbag 3, and the short airbag 4 are all fixedly connected with sub-hook and loop fasteners 11, and the bottoms of the annular groove 8, the long groove 9, and the short groove 10 are fixedly connected with female hook and loop fasteners 12 corresponding to the positions of the sub-hook and loop fasteners 11.
[0031] Among them, the annular groove 8, the long groove 9 and the short groove 10 respectively install and separate the annular airbag 2, the long airbag 3 and the short airbag 4 to avoid mutual compression between the annular airbag 2, the long airbag 3 and the short airbag 4.
[0032] Furthermore, the ring airbag 2, long airbag 3, and short airbag 4 are detachably connected by the sub-hook and hook and loop fastener 11 and the mother hook and loop fastener 12, which facilitates replacement when the ring airbag 2, long airbag 3, or short airbag 4 is damaged.
[0033] By using this method, when the patient needs to change posture, such as from lying down to sitting, the support pad can be folded at a certain angle by removing one or more of the long air bladders 3 or deflating them, so that the patient can prevent pressure sores while sitting or leaning.
[0034] In addition, when adjusting the support area of the patient's sacrum, the number of ring-shaped airbags 2 used can be changed by assembling and disassembling them, thereby achieving the purpose of adjusting the support area.
[0035] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
