Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical care equipment technology, and more specifically, to a pressure injury prevention mattress. Background Technology
[0002] Pressure injuries are localized damage to the skin and / or underlying tissues at bony prominences caused by external pressure. Patients who are bedridden or have limited mobility are prone to pressure injuries due to prolonged periods in the same position, leading to impaired local blood circulation. Currently, clinical practice routinely requires patients to be turned regularly to prevent pressure injuries; however, this method not only increases the workload of nursing staff but may also be ineffective due to improper operation or patient non-compliance.
[0003] Existing pressure injury prevention mattresses, especially air mattresses, while able to alleviate pressure to some extent, still have many shortcomings. For example, some air mattresses have large individual air units in their air layers, resulting in a larger contact area with the patient's body. This limits the pressure-relief effect and fails to effectively distribute body pressure. Furthermore, the large contact area leads to poor ventilation and breathability, easily causing discomfort such as dampness and stuffiness, which may exacerbate the risk of pressure injuries.
[0004] In view of this, the present invention proposes a pressure injury prevention and care mattress to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a pressure injury prevention and care mattress. By optimizing the structure of the air-filled unit, it achieves precise support and pressure relief for various parts of the patient's body, effectively dispersing body pressure, effectively preventing and treating pressure injuries, and improving the pressure relief effect. At the same time, it can enhance the ventilation and breathability of the mattress, keep the patient's skin surface dry and fresh, and improve the patient's comfort.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A pressure injury prevention and care mattress includes a pressure-reducing pad, a mattress border, and a bottom pad. The bottom pad is provided with a pressure-reducing pad composed of multiple sets of airbag pressure-reducing units evenly arranged. The pressure-reducing pad is surrounded by a mattress border, and the bottom of the mattress border is sewn to the bottom pad. The bottom pad is also provided with a ventilation component.
[0008] The airbag decompression unit includes a sponge pad, a cylindrical decompression airbag, and silicone particle filler. The upper end of the cylindrical decompression airbag is fixedly connected to the sponge pad, and the sponge pad is filled with silicone particle filler.
[0009] Furthermore, the upper surface of the base pad is provided with multiple sets of fabric strips arranged longitudinally and evenly, and the bottom of the columnar decompression airbag is sewn with Velcro, and the bottom of the columnar decompression airbag is detachably attached to the fabric strips via Velcro.
[0010] Furthermore, each set of columnar decompression airbags has an airbag strap on its outer surface, and the airbag straps are stitched together to form a mesh structure. The mesh structure of the airbag straps is fixedly sewn to the mattress edge.
[0011] Furthermore, the ventilation component includes an air cushion layer, silicone ventilation tubes, air pipes, an air pump, and air holes. The air cushion layer is disposed inside the base pad. Multiple sets of silicone ventilation tubes are uniformly fixed on the upper surface of the air cushion layer, and the bottom of the silicone ventilation tubes is connected to the interior of the air cushion layer. The silicone ventilation tubes are located in the gaps between four adjacent sets of columnar decompression airbags. Multiple sets of air holes for air outlet are uniformly opened on the upper end face of the silicone ventilation tubes. One end of the air cushion layer is connected to an air pipe, and the outer end of the air pipe is sealed and connected to the output end of the air pump.
[0012] Furthermore, a semi-circular groove adapted to the silicone ventilation tube is provided at the edge of the fabric layer, and the silicone ventilation tube extends through the bottom pad and passes through the groove.
[0013] Furthermore, the length of the silicone ventilation tube is one-third of the length of the cylindrical decompression airbag.
[0014] Furthermore, the base pad is made of latex.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. This utility model optimizes the structure of the air-filled unit and adopts a refined zoning design to divide the mattress surface into multiple small areas, thereby achieving precise support and pressure relief for various parts of the patient's body, effectively dispersing body pressure, effectively preventing and treating pressure injuries, improving the pressure relief effect, and at the same time enhancing the ventilation and breathability of the mattress, keeping the patient's skin surface dry and fresh, and improving the patient's comfort.
[0017] 2. In this utility model, the pressure-reducing pad layer of the mattress is composed of multiple sets of airbag pressure-reducing units evenly arranged. The columnar pressure-reducing airbags are smaller in volume, reducing the contact area with the patient's body, which can more effectively disperse body pressure and provide a better pressure-reducing effect. The inside of the sponge pad is filled with silicone particle filler. The sponge pad and silicone particle filler provide a soft contact surface, increasing the patient's comfort and effectively relieving pressure on the contact surface.
[0018] 3. In this invention, the bottom of the cylindrical pressure-relieving airbag is detachably connected to the fabric strap via Velcro, allowing for easy disassembly and replacement. When the cylindrical pressure-relieving airbag is damaged or needs cleaning, it can be easily removed from the base for replacement or cleaning without disassembling or replacing the entire mattress.
[0019] 4. The ventilation component in this utility model is used to blow air from inside the mattress to the patient's body contact surface, thereby achieving ventilation and allowing the air inside the mattress to circulate smoothly. This improves ventilation efficiency, helps reduce discomfort such as dampness and stuffiness caused by prolonged lying down, reduces the risk of pressure injury, and enhances the patient's lying experience.

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0032] Example:
[0033] like Figures 1 to 10 As shown, a pressure injury prevention and care mattress includes a pressure-reducing pad 1, a mattress border 2, and a bottom pad 3. The bottom pad 3 is provided with a pressure-reducing pad 1 composed of multiple sets of airbag pressure-reducing units evenly arranged. The pressure-reducing pad 1 of the mattress is composed of multiple sets of airbag pressure-reducing units evenly arranged, which can effectively disperse the pressure of various parts of the patient's body and avoid pressure injury caused by excessive pressure at a single point. At the same time, the pressure-reducing pad 1 composed of multiple sets of airbag pressure-reducing units evenly arranged has more breathable space inside, providing better ventilation and breathability. The pressure-reducing pad 1 is surrounded by a mattress border 2, and the bottom of the mattress border 2 is sewn to the bottom pad 3. The bottom pad 3 is also provided with a ventilation component 4, which is used to blow air from inside the mattress to the patient's body contact surface to achieve ventilation and breathability.
[0034] The airbag decompression unit includes a sponge pad 11, a cylindrical decompression airbag 12, and silicone particle filler 14. The sponge pad 11 is fixedly connected to the upper end of the cylindrical decompression airbag 12. The smaller volume of the cylindrical decompression airbag 12 reduces the contact area with the patient's body, allowing for more effective distribution of body pressure and providing better decompression. The sponge pad 11 is filled with silicone particle filler 14, providing a soft contact surface that increases patient comfort and effectively relieves pressure. This design solves the problem that inflatable mattresses often have large single-unit air inflatable layers, resulting in a large contact area with the patient's body, which limits the decompression effect and fails to effectively distribute body pressure. Furthermore, the large contact area can lead to poor ventilation and breathability on the patient's body, causing discomfort such as dampness and stuffiness, potentially increasing the risk of pressure injuries.
[0035] In this embodiment, multiple sets of fabric tape layers 6 are evenly arranged longitudinally on the upper surface of the base pad 3. The bottom of the columnar pressure-reducing airbag 12 is sewn with Velcro 13, allowing for detachable adhesion between the bottom of the airbag and the fabric tape. The fabric tape layers 6 provide stable support and fixing points for the columnar pressure-reducing airbag 12. This design allows the airbag to be easily attached to the fabric tape layers 6 of the base pad 3. The detachable connection between the bottom of the airbag and the fabric tape allows for easy removal and replacement of the airbag. When the airbag is damaged or needs cleaning, it can be easily removed from the base pad 3 for replacement or cleaning without disassembling or replacing the entire mattress.
[0036] In this embodiment, each set of columnar pressure-reducing airbags 12 has an airbag strap 5 fitted on its outer surface. The airbag straps 5 are stitched together to form a mesh structure, and the mesh structure of the airbag straps 5 is fixedly sewn to the mattress edge 2 around its perimeter. The mesh structure of the airbag straps 5 creates a stable support network between the airbag pressure-reducing units, which positions and restrains the airbag pressure-reducing units, preventing the columnar pressure-reducing airbags 12 from shifting during use. At the same time, the mesh structure of the airbag straps 5 can connect and support the mattress edge 2 from the inside.
[0037] In this embodiment, the ventilation component 4 includes an air cushion layer 41, silicone ventilation tubes 42, air pipes 43, an air pump 44, and air holes 45. The air cushion layer 41 is disposed inside the base pad 3. Multiple sets of silicone ventilation tubes 42 are uniformly fixed on the upper surface of the air cushion layer 41, and the bottom of the silicone ventilation tubes 42 is connected to the inside of the air cushion layer 41. The silicone ventilation tubes 42 are located in the gaps between four adjacent sets of columnar decompression airbags 12. Multiple sets of air holes 45 for air outlet are uniformly opened on the upper end face of the silicone ventilation tubes 42. One end of the air cushion layer 41 is connected to the air pipe 43, and the outer end of the air pipe 43 is sealed and connected to the output end of the air pump 44. The ventilation component 4 is used to blow air from inside the mattress to the patient's body contact surface to achieve ventilation and breathability, so that the air inside the mattress can circulate smoothly, improve ventilation efficiency, help reduce the discomfort such as dampness and stuffiness caused by prolonged lying down, reduce the risk of pressure injury, and improve the patient's lying experience. When ventilation is required, the air pump 44 is started. The air pump 44 inflates the air cushion layer 41 through the air tube 43. The air in the air cushion layer 41 flows into the silicone ventilation tube 42 and is finally blown out through the air hole 45 on the silicone ventilation tube 42. After the air is blown out, it flows along the gap inside the pressure-reducing pad layer 1 and is blown towards the patient's body surface to achieve ventilation.
[0038] In this embodiment, a semi-circular groove 61 adapted to the silicone ventilation tube 42 is provided at the edge of the fabric layer 6. The silicone ventilation tube 42 extends through the bottom pad 3 and passes through the groove 61. The design of the groove 61 ensures that the silicone ventilation tube 42 can pass smoothly through the fabric layer 6 without being obstructed or damaged.
[0039] In this embodiment, the length of the silicone ventilation tube 42 is one-third of the length of the columnar decompression airbag 12. This design allows the silicone ventilation tube 42 to meet the ventilation needs, while preventing the columnar decompression airbag 12 from coming into contact with the patient's body when it is deformed by pressure, thus avoiding patient discomfort and blockage of the air vent 45.
[0040] In this embodiment, the base pad 3 is made of latex. Latex has excellent elasticity and support, and can deform evenly under pressure, thereby evenly distributing body pressure, reducing localized pressure, and thus reducing the risk of pressure injuries. Latex material has natural air pores 45, allowing air to circulate freely and effectively expel moisture from inside the mattress, keeping it dry. This breathability helps reduce bacterial growth and maintain the mattress's hygiene and cleanliness.
[0041] The working principle of this pressure injury prevention and care mattress:
[0042] The pressure-relief layer 1 of the mattress is composed of multiple sets of evenly arranged airbag pressure-relief units. Each airbag pressure-relief unit includes a cylindrical pressure-relief airbag 12, the upper end of which is fixedly connected to a sponge pad 11, the sponge pad 11 being filled with silicone particle filler 14. The cylindrical pressure-relief airbag 12 is small in size, reducing the contact area with the patient's body, thereby more effectively dispersing body pressure and providing a better pressure-relief effect. The sponge pad 11 and silicone particle filler 14 provide a soft contact surface, increasing patient comfort and effectively relieving pressure on the contact surface. The bottom pad 3 is equipped with a ventilation component 4, including an air cushion layer 41, a silicone ventilation tube 42, an air tube 43, an air pump 44, and air holes 45. When the air pump 44 is working, airflow enters the silicone ventilation tube 42 through the air cushion layer 41 and is blown out from the air holes 45, blowing air onto the patient's body contact surface to achieve ventilation. This helps reduce discomfort such as dampness and stuffiness caused by prolonged lying down, and reduces the risk of pressure injury. The bottom of the columnar pressure-reducing airbag 12 is sewn with Velcro 13, which is detachably attached to the fabric layer 6. When the columnar pressure-reducing airbag 12 is damaged or needs cleaning, it can be easily removed from the base pad 3 for replacement or cleaning without disassembling or replacing the entire mattress.
[0043] In summary, this pressure injury prevention mattress provides a comfortable lying environment for patients through the pressure-dispersing function of the airbag decompression unit and the ventilation component 4, effectively preventing the occurrence of pressure injuries.
[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
