Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an anti-pressure sore mattress. Background Art

[0002] Pressure sores, or pressure injuries, are a type of skin ulcer formed when human skin tissue, especially bony protrusions, is compressed, sheared, or rubbed. They are most common in the elderly and patients of any age who are unable to adjust their position in bed.

[0003] Existing mattresses are composed of multiple detachable cushion materials, which are prone to slippage and wear between parts due to force during use. Adding components to reduce offset and shaking not only makes the processing process cumbersome, but also increases the cost. In addition, although air fibers have good air permeability, they cannot absorb and discharge moisture if bedridden patients sweat, have urinary incontinence, etc. At this time, the patient should be cared for in time to avoid moisture from penetrating the skin. Existing mattresses use sensors for real-time monitoring, which is costly and energy-intensive, and imposes a heavy economic burden on patients. Utility Model Content

[0004] The utility model provides an anti-pressure sore mattress, which solves the technical problems of slippage and wear of the mattress due to external force, complicated mattress manufacturing process, high cost and high energy consumption of real-time monitoring of the mattress status.

[0028] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an anti-pressure sore mattress, comprising:

[0030] Bed core 1;

[0031] A bed cover 2 covering the outside of the bed core 1;

[0032] The bed core 1 comprises a solid fiber layer 11 and a hollow fiber layer 12 connected to the solid fiber layer 11;

[0033] The solid fiber layer 11 and the hollow fiber layer 12 are both three-dimensional winding structures;

[0034] The bedspread 2 comprises a cover body and a color-changing fabric layer arranged on the outer surface of the cover body.

[0035] In the above embodiment, the bed cover 2 has the same shape as the bed core 1 and is tightly wrapped around the outside of the bed core 1. By arranging a solid fiber layer 11 in the bed core 1, it can conform to the human body's sleeping curve, effectively support and disperse the pressure of the human body, especially the bony protrusions, and play a role in relieving pressure. By arranging a hollow fiber layer 12 in the bed core 1, it can provide a buffering support effect. The thickness of the solid fiber layer 11 is greater than that of the hollow fiber layer 12, and the hardness of the solid fiber layer 11 is less than that of the hollow fiber layer 12, so that the mattress of the utility model has the advantages of both the solid fiber layer 11 and the hollow fiber layer 12, that is, it can provide sufficient support while relieving the pressure of various parts of the human body and providing a buffering effect.

[0036] The solid fiber layer 11 and the hollow fiber layer 12 are formed by heating and melting the raw materials and extruding them through a die head to form fiber filaments. When the fiber filaments fall to the water surface, they are entangled and bonded to each other under the action of buoyancy and water surface ripples, and finally are water-cooled to form a three-dimensional winding structure. By adopting the solid fiber layer 11 and the hollow fiber layer 12 of the three-dimensional winding structure, the bed core 1 has high elasticity and high air permeability.

[0037] The color-changing fabric layer is located on the outer surface of the cover body, and the size of the color-changing fabric layer is smaller than the cover body and is arranged at a position where the cover body is easily in contact with liquid when in use. When the bedridden user sweats, has urinary incontinence, etc., the color-changing fabric layer can change color, thereby reminding the nursing staff to turn the user over, clean the user, and other care. Furthermore, the cover body is made of one of the commonly used fabrics such as cotton and linen fabrics, silk fabrics, bamboo charcoal fibers, etc., with a thickness ranging from 0.8mm to 1.5mm, which is not only wear-resistant but also easy to clean.

[0038] In an optional embodiment of the present invention, the solid fiber layer 11 and the hollow fiber layer 12 are integrally formed.

[0039] In the above embodiment, the solid fiber layer 11 and the hollow fiber layer 12 are integrally formed, which not only has a simple processing technology and is environmentally friendly, but also can prevent the bed core 1 from being worn due to relative slip during transportation and use.

[0040] In an optional embodiment of the present invention, the solid fiber layer 11 and the hollow fiber layer 12 are both made of polyolefin elastomer or thermoplastic polyester elastomer.

[0041] In the above embodiment, by using one of polyolefin elastomer (POE) and thermoplastic polyester elastomer (TPEE) as the fiber filaments constituting the solid fiber layer 11 and the hollow fiber layer 12, not only can the bed core 1 be directly washed with water without deformation or damage, but the process is simple and environmentally friendly, and it is easy to wash and dry quickly.

[0042] In an optional embodiment of the present invention, the solid fiber layer 11 is thicker than the hollow fiber layer 12 .

[0043] In the above embodiment, the overall thickness range of the anti-pressure sore mattress of the utility model is 8cm-12cm, and the thickness of the solid fiber layer 11 is greater than half of the overall thickness of the anti-pressure sore mattress, which can not only fully relieve pressure, but also reduce costs because the raw materials used in the solid fiber layer 11 are less than those of the hollow fiber layer 12.

[0044] In an optional embodiment of the present invention, the hardness of the solid fiber layer 11 is less than that of the hollow fiber layer 12 .

[0045] In the above embodiment, by setting the degree of winding of the fiber filaments and the diameter of the fiber filaments during processing, the hardness of the solid fiber layer 11 is made smaller than the hardness of the hollow fiber layer 12. By setting the processing time, the thickness of the hollow fiber layer 12 is made smaller than the thickness of the solid fiber layer 11. In actual use, the user can select the side of the hollow fiber layer 12 with greater hardness as the contact surface for use, or select the part of the solid fiber layer 11 with less hardness as the contact surface for use according to his own preferences or needs.

[0046] In an optional embodiment of the present invention, the hardness range of the bed core 1 is 40D-75D.

[0047] In an optional embodiment of the present invention, the hardness of the solid wire layer 11 ranges from 40D to 50D;

[0048] The hardness of the hollow fiber layer 12 is in the range of 50D-70D.

[0049] In the above two embodiments, the hardness of the solid fiber layer 11 is less than that of the hollow fiber layer 12, so that the hardness of the anti-pressure sore mattress is reduced, the use feeling is softer, and it can better conform to the human body's sleeping curve. It can also prevent the body tissue from causing pressure sores due to hypoxia, ischemia and insufficient supply of nutrients caused by continuous pressure.

[0050] The unit D is the Shore hardness unit.

[0051] In an optional embodiment of the present invention, the color-changing fabric layer is made of a moisture-sensitive color-changing dye.

[0052] In the above embodiment, the moisture-sensitive color-changing dye is a reversible color-changing cobalt complex salt, which causes lattice transformation and ligand geometric configuration changes through the gain and loss of crystal water, so that the energy required for electron dd transition is different, thereby reversibly changing the absorption spectrum of visible light, thereby showing different colors. The change is reversible. When in use, the color-changing fabric layer appears blue when dry. If sweating, urinary incontinence, etc. occur during use, the color-changing fabric layer sequentially shows a visible color change from blue-blue-purple-purple-purple, thereby reminding the user to turn over, clean, and other care.

[0053] In an optional embodiment of the present utility model, a zipper 3 is provided on the side of the bedspread;

[0054] The color-changing fabric layer is tightly bonded to the cover body.

[0055] In the above embodiment, a zipper 3 is provided on the side of the bed cover, which facilitates the removal of the bed cover 2 for washing.

[0056] The color-changing fabric layer can be made into various patterns according to needs. The first step is to design the pattern, the second step is to make a printing plate of the pattern, the third step is to add the moisture-sensitive color-changing dye to a compatible adhesive and a thickener to make a printing paste, and fix the printing plate on the cover body, the fourth step is to apply the printing paste from the hollow part of the printing plate to the cover body by scraping, and the fifth step is to firmly adhere the moisture-sensitive color-changing dye to the outer surface of the cover body through the adhesive in the printing paste after drying.

[0057] The use method of the anti-pressure sore mattress of the utility model is as follows:

[0058] After unpacking, it can be placed on a flat bed frame for direct use. When using, you can choose a side with greater or lesser hardness as the contact surface according to your own preferences or needs. During use, if the bedridden patient sweats, has urinary incontinence, etc., the color-changing fabric layer will change from blue to purple or purple-red, and the nursing staff can roughly judge the degree of care required according to the color indicated by the fabric, so as to turn the patient over, clean the patient, etc., reducing the difficulty of care and monitoring. If necessary, the bed cover 2 can be removed through the zipper 3 for hand washing or machine washing, and the bed core 1 can be directly rinsed with clean water and dried at room temperature.

[0059] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
