Technical Field

[0001] This utility model relates to the field of medical and nursing device technology, and in particular to a multifunctional pressure ulcer prevention pad. Background Technology

[0002] Pressure ulcers, also known as bedsores or pressure sores, are caused by prolonged pressure on local tissues, leading to persistent ischemia, hypoxia, malnutrition, and ultimately tissue necrosis and ulceration. Pressure ulcers commonly occur in patients who are bedridden for extended periods, not only increasing their suffering but also potentially causing complications such as infection, severely impacting their recovery.

[0003] Currently, there are many types of pressure ulcer pads on the market, such as inflatable pressure ulcer pads, foam pressure ulcer pads, and water pads. However, most existing pressure ulcer products only provide physical pressure relief and cannot assist in the treatment of existing mild pressure ulcers, nor can they effectively prevent the occurrence of pressure ulcers. Traditional Chinese medicine has a long history and rich experience in treating sores and ulcers. Combining Chinese herbal ingredients with pressure ulcer pads to achieve both prevention and adjunctive treatment functions is a technical problem that urgently needs to be solved. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional pressure ulcer prevention pad.

[0022] Example 1 A multifunctional pressure ulcer prevention pad, such as Figure 1 As shown, it includes a seat cushion 1 and a functional unit used in conjunction with the seat cushion 1.

[0023] like Figure 2As shown, the seat cushion 1 measures 45×45×8cm (fitting a standard wheelchair seat width of 40-45cm). A groove 101 is provided in the center of the seat cushion 1. The seat cushion 1 includes two symmetrically arranged protective half-cushions 103, which are detachably connected. In this embodiment, a zipper 104 connects the two protective half-cushions 103. The groove 101 can be elliptical, rectangular, or square in shape, and its position corresponds to the patient's buttocks. The groove 101's alignment with the patient's buttocks allows the buttocks to be suspended, providing ventilation and effectively preventing pressure sores.

[0024] If the ventilation effect of the ventilation area formed by the groove 101 alone is not good during use, the two protective half pads 103 can be disassembled and placed under the patient's buttocks at a certain distance to increase the ventilation volume and reduce the accumulation of moisture and heat.

[0025] A first through hole 102 is provided through the center of the groove 101. Half of the first through hole 102 is provided on each of the two protective half-pads 103, and the two are combined to form a complete channel structure. Four second through holes 1031 are provided through the cushion 1, and two second through holes 1031 are provided on each of the protective half-pads 103. The diameter of both the first through hole 102 and the second through hole 1031 is 5 cm.

[0026] Four second through holes 1031 and one first through hole 102 are arranged in a cross shape, with the first through hole 102 located at the exact center of the cross. In use, a herbal medicine pack is placed in each of the first through holes 102 and 1031. The herbal ingredients in the pack help prevent pressure sores and also provide adjunctive treatment for mild pressure sores on the patient's buttocks. The first and second through holes 102 and 1031 not only hold the herbal medicine pack but also provide ventilation to maintain breathability.

[0027] The first through hole 102 and the second through hole 1031 set in this embodiment, along with the Chinese medicine pack placed therein, are collectively referred to as the five-hole herbal filling system.

[0028] The herbal pack can contain different herbs depending on the specific needs, such as one or more of the following: Lithospermum root powder, dried lavender flowers, Apocynum venetum leaves, Camel thorn flowers, and licorice powder. Lithospermum root powder is a traditional medicinal plant from Hotan region, known for its significant effect in reducing the incidence of pressure sores; dried lavender flowers are a specialty of Ili, a cultural symbol, and have calming, sleep-inducing, and Staphylococcus aureus-inhibiting effects; Apocynum venetum leaves are a wild plant from the Tarim River basin, known for improving local blood circulation (the *Uyghur Materia Medica* records its muscle-relaxing and blood-activating effects); Camel thorn flowers are unique to the southern Xinjiang desert, known for their anti-inflammatory and swelling-reducing effects; and licorice powder is a major medicinal material in Xinjiang, known for its skin barrier function (the *Compendium of Materia Medica* states that it "promotes muscle growth and heals wounds"). This utility model's five-acupoint herbal filling system emphasizes the concept of "Xinjiang native medicinal plants," enhancing cultural belonging.

[0029] The ingredients inside the herbal medicine packet can be formulated according to specific needs. The herbal medicine packet needs to be replaced regularly, ideally every two weeks. The herbal medicine packet is made of non-woven fabric, which is breathable and prevents powder leakage.

[0030] The two functional pads 2 are detachably connected via zippers or Velcro, with Velcro being the preferred method. Through simple disassembly and reassembly, the two functional pads 2 can be used as a lumbar support, armrest, or leg rest: When experiencing lower back pain from prolonged sitting, the combined functional pad 2 can be placed directly behind the lower back to support the lumbar muscles and relieve pressure; for prolonged arm support (such as wheelchair armrests), the individual functional pad 2 can be used as an armrest to reduce arm pressure; for leg discomfort, the two separate functional pads 2 can be placed under the thighs or calves to distribute pressure and prevent pressure sores or aches. Whether the patient is sitting in a wheelchair for extended periods, resting in bed, or engaging in daily activities, the use of the two functional pads 2 can be adjusted according to the actual physical discomfort.

[0031] Both the protective half-cushion 103 and the functional cushion 2 use bamboo charcoal memory foam as their core material. Bamboo charcoal memory foam has antibacterial and far-infrared circulation-promoting properties (experiments have shown it reduces skin moisture by 27%), which is superior to ordinary sponge. The core material can be divided into density zones. The edges of the seat cushion 1 use higher-density bamboo charcoal memory foam, which is firmer and provides solid support. The central area of ​​the seat cushion 1, corresponding to the main pressure points such as the buttocks and ischial tuberosities, uses lower-density bamboo charcoal memory foam.

[0032] The inner core material is covered by an outer cover made of Atlas silk fabric. Atlas silk is a Xinjiang intangible cultural heritage craft, with colors derived from mineral / plant dyes (such as tamarisk root and walnut shell), making it natural and safe. A cotton-Atlas silk blend fabric can also be used, with a 100% cotton inner layer that is moisture-wicking and breathable, and an outer layer featuring an Atlas silk pattern, balancing cultural aesthetics with comfort.

[0033] The Atlas silk features classic patterns in red (representing youthful vitality) and yellow (representing wealth and elegance), with a symmetrical layout that echoes the pores in the herbal medicine. The Kunlun Mountains pattern symbolizes support, while the curves of the Yulongkash River represent blood flow (implicitly suggesting a function to prevent pressure sores). The bottom of the seat cushion 1 is embedded with an anti-slip silicone strip. The two sides of the seat cushion 1 are respectively equipped with straps 3 for fixing the seat cushion 1 to the wheelchair or hospital bed.

[0034] The two straps 3 are respectively connected to the two protective half pads 103, as follows: Figure 3 As shown, the protective half-cushion 103 has a fixing strip 4 on its side wall. The left and right ends of the fixing strip 4 are sewn together with the protective half-cushion 103, and the upper and lower ends of the fixing strip 4 are connected. One end of the strap 3 has a through hole 301. After the end of the strap 3 with the through hole 301 passes through the fixing strip 4, the end of the strap 3 away from the through hole 301 passes through the through hole 301. In use, the end of the strap 3 away from the through hole 301 can be tied to the wheelchair frame or hospital bed. In this embodiment, the strap 3 and the cushion 1 are detachably connected. When the strap 3 is not needed for fixation, it can be directly removed.

[0035] Existing pressure ulcer prevention pads have the following problems: 1. Limited function: Most products on the market are only designed for a single body position (such as supine), lacking adaptability to multiple body parts (arms / legs / waist); 2. Non-breathable material: Traditional memory foam or gel pads tend to accumulate heat and moisture with long-term use, exacerbating the risk of pressure ulcers; 3. Lack of adjunctive treatment: Very few are combined with natural therapies such as herbal medicine to enhance the preventive effect; 4. Lack of cultural elements: Medical device design ignores the expression of regional culture.

[0036] The multifunctional pressure ulcer prevention pad provided by this utility model combines pressure prevention, ventilation, and traditional Chinese medicine auxiliary functions through the design of the seat cushion, groove, through holes, and functional pad. It adopts Xinjiang regional medicinal materials and Adelaide silk fabric, which are deeply integrated with culture. It not only solves the pain points of clinical pressure ulcer prevention, but also promotes the innovative application of intangible cultural heritage. In the future, it can be used in conjunction with the Xinjiang Adelaide Silk R&D Center for material trial production and conduct interdisciplinary clinical verification.

[0037] Example 2 A multifunctional pressure ulcer prevention pad. The technical solution in this embodiment is basically the same as that in the previous embodiment, except that: (1) the connection method between the functional pad 2 and the seat cushion 1 has been optimized in this embodiment; (2) a removable isolation liner 9 is provided in the first through hole 102 and the second through hole 1031 in this embodiment.

[0038] Two protective half-pads 103 have extension strips 5 on the side closest to the back of the person. Both extension strips 5 are connected to one of the functional pads 2 along their length via a first connector 6, which preferably uses a zipper. When the patient is sitting in a wheelchair and needs to use the functional pad 2 as a lumbar support, it can be connected to the seat cushion 1 via the first connector 6 to prevent the functional pad 2 from moving.

[0039] The two protective half-pads 103 are connected to the two functional pads 2 in the width direction via a second connector 7 on the side closest to the human leg. The second connector 7 preferably uses Velcro. Figure 4 and Figure 5 As shown, the protective half-cushion 103 has a Velcro surface on the side closest to the legs, and the functional cushion 2 has a Velcro hook surface on its sidewall in the width direction. When the patient needs support for their thighs while sitting on the bed, the two functional cushions 2 can be detached and connected to the protective half-cushion 103 via the second connector 7. When supporting the lower legs, the cushions can be placed directly under the lower legs without needing to be connected to the seat cushion 1.

[0040] In this embodiment, the seat cushion 1 and the functional cushion 2 are connected by the first connector 6. When the functional cushion 2 is used as a lumbar support cushion, it can be firmly fixed to the seat cushion 1, preventing the functional cushion 2 from shifting and losing its support when the patient moves in the wheelchair, thus ensuring the effectiveness of lumbar protection. This is especially suitable for long-term use by patients with limited mobility. The functional cushion 2 is connected to the protective half-cushion 103 by the second connector 7. When the patient is lying down and needs support for the thighs, the functional cushion 2 can be quickly fixed to the seat cushion 1 with Velcro, ensuring accurate support position. When supporting the lower legs, no connection is required; it can be placed directly, reducing unnecessary operations, adapting to the support needs of different body parts, and improving the flexibility of use.

[0041] In this embodiment, removable insulating liners 9 are placed in the first through hole 102 and the second through hole 1031 respectively to prevent the herbal powder from leaking out and contaminating the seat cushion. The shape of the insulating liners 9 matches the inner wall shape of the first through hole 102 or the second through hole 1031, and the insulating liners 9 have a top-opening and bottom-closed structure. Figure 6 As shown, five insulating liners 9 are fixed to connecting strips 8, which are cross-shaped and have five through holes. An insulating liner 9 is sewn below each through hole. The connecting strips 8 are made of soft fabric and have creases at positions corresponding to the edge of the groove 101. When the insulating liners 9 are placed into the first through hole 102, the connecting strips 8 fit against the bottom and side walls of the groove 101.

[0042] The four ends of the connecting strip 8 are fixed to the bottom of the seat cushion 1 with Velcro. When it is necessary to place the herbal medicine pack on the seat cushion 1, simply place the connecting strip 8 on the seat cushion 1, insert the five insulating liners 9 into the first through hole 102 and the second through hole 1031 respectively, fix the four ends of the connecting strip 8 to the bottom of the seat cushion 1, and finally place the herbal medicine pack.

[0043] During the design and manufacturing process, the connecting strip 8 and the insulating lining 9 can be made of double-layered fabric. An electric heating component is placed between the two layers of fabric in the insulating lining 9, and a connecting line is placed between the two layers of fabric in the connecting strip 8 to connect to an external power source. The heating component heats the herbal pack, and the heat effect accelerates the release of the active ingredients in the herbs, thereby improving the adjuvant therapeutic effect.

[0044] This embodiment integrates five insulating linings 9 with a cross-shaped connecting strip 8, with the four ends of the connecting strip 8 fixed to the seat cushion 1 via Velcro. This has the following advantages: Easy installation: Simply place the connecting strip 8 on the cushion 1, insert the isolation liner 9 into the corresponding through hole and fix the end of the connecting strip 8 to quickly complete the preparation for placing the Chinese medicine pack. The operation is simple and efficient. Easier to clean and dry: When disassembling, simply unfasten the connecting strip 8 from the seat cushion 1 to remove all five isolation linings 9 at once, without having to disassemble them one by one, reducing the number of cleaning steps; at the same time, the modular structure facilitates centralized drying, improving cleaning efficiency and reducing the workload of maintenance.

[0045] The fastening method (zipper / Velcro) between the connecting strip 8 and the seat cushion 1 is adapted to different usage scenarios and can be completely removed when not needed; the isolation lining 9 is reusable, reducing the cost of consumables, and can be kept hygienic after washing.

[0046] The multifunctional pressure ulcer prevention pad provided by this utility model integrates the design of pressure ulcer protection equipment, the cultural characteristics of Adelaide silk, and the application of local Xinjiang herbs. It solves the problems of poor ventilation and lack of auxiliary treatment effect of existing pressure ulcer prevention pad products, and incorporates Xinjiang cultural elements, realizing multiple values ​​of functional upgrade, experience optimization and cultural empowerment.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
