Description

Technical Field

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

[0002] In recent years, with the rapid development of surgical techniques, particularly the application of minimally invasive techniques and neoadjuvant therapies, significant progress has been made in the anal preservation treatment of mid- and low-rectal cancer. The Dixon procedure, a classic anal preservation procedure, has gained widespread popularity due to its ability to radically remove the tumor while preserving anal function. However, despite these advances in surgical techniques, several issues regarding postoperative care and rehabilitation remain unresolved.

[0003] After rectal cancer surgery, in order to reduce the incidence of anastomotic fistula, an anal tube is often required for drainage and decompression. The traditional way to fix the anal canal is to fix it directly to the patient's perianal skin with sutures. Although this method is simple, it also has certain disadvantages. Specifically, when the patient lies flat on the bed, due to the hardness and flatness of the mattress, as well as the limitations of the patient's body position, the anal canal is often subjected to varying degrees of compression, which in turn causes discomfort to the patient and may even affect the healing process of the anastomosis. In addition, the skin in the perianal area is delicate and rich in nerve endings, and is extremely sensitive to stimulation. The method of fixing the anal canal with sutures may not only increase the patient's pain, but may also cause adverse reactions such as local redness, swelling, and damage due to factors such as skin pressure and friction, further affecting the patient's postoperative recovery and quality of life. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide an anti-pressure ulcer mattress to solve the technical problems mentioned in the above background technology.

[0023] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0024] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] See also Figures 1 to 4 The anti-pressure sore mattress in the present invention includes a mattress body 10, and a concave cavity 11 is provided on the mattress body 10. The inner wall of the concave cavity 11 is provided with a plurality of annular air bags 20 in sequence toward the center. Each of the annular air bags 20 can be independently inflated or deflated, thereby realizing the adjustment of the opening size of the concave cavity 11.

[0028] By designing a cavity 11 within the mattress body 10, space is directly provided for the anal canal, which is sewn to the patient's anus. This prevents direct pressure on this area while the patient is in bed, significantly reducing the risk of pressure ulcers. Furthermore, multiple independently controllable annular airbags 20 are positioned within the cavity 11, allowing medical staff to flexibly adjust the opening size of the cavity 11 based on the size of the patient's hips, thereby ensuring patient comfort while in bed and helping to alleviate the discomfort associated with prolonged bed rest.

[0029] Specifically, in this embodiment, the outline of the cavity 11 is elliptical, so the outline of the annular airbag 20 arranged on the inner wall of the cavity 11 is also elliptical, which can more closely wrap and support the patient's buttocks and perineum area, effectively disperse the pressure, and alleviate the problem of poor blood circulation caused by long-term pressure.

[0030] In this embodiment, the number of the annular airbags 20 is three, and medical staff can flexibly adjust the size of the opening of the cavity 11 according to the size of the patient's buttocks. Specifically, when the three annular airbags 20 are inflated, the opening size of the cavity 11 is the smallest. When only the two annular airbags 20 close to the inner wall of the cavity 11 are inflated, the opening size of the cavity 11 is moderate. When the three annular airbags 20 are deflated, the opening size of the cavity 11 is the largest.

[0031] See Figure 3 The two adjacent annular airbags 20 are connected by a connecting piece 21. The connecting piece 21 has a plurality of magnetic blocks 22 in a circular array. The inner circumference of the innermost annular airbag 20 is provided with a plurality of magnets 23. It is understandable that when medical personnel deflate the innermost annular airbag 20 to reduce the opening size of the cavity 11, as the gas in the innermost annular airbag 20 is gradually released, the magnets 23 will be attracted to the magnetic blocks 22, thereby allowing the deflated annular airbag 20 to fit tightly against the inner circumference of the adjacent annular airbag 20, preventing the deflated annular airbag 20 from occupying too much space in the middle of the cavity and ensuring that the opening of the cavity 11 is maximized. The same principle applies when the annular airbag 20 in the middle is deflated. When the annular airbag 20 in the middle is deflated, the two magnetic blocks 22 attract each other, allowing the deflated annular airbag 20 in the middle to fit tightly against the inner circumference of the outermost annular airbag 20.

[0032] See Figure 4The side edges of the mattress body 10 are provided with multiple channels 30 extending into the concave cavity 11. An inflation tube 32, provided on each annular airbag 20, extends through the channel 30. The exposed end of the inflation tube 32 is provided with an inflation bag 33 and a one-way valve 34, which acts as a seal. In practice, medical personnel can inflate each annular airbag 20 by repeatedly squeezing the inflation bag 33. To deflate an annular airbag 20, they adjust the one-way valve 34 to allow air to flow out of the annular airbag 20 in the reverse direction. This manual inflation method is simple and quick, requiring no additional power source or equipment, making it ideal for use in hospitals, rehabilitation centers, or home care settings.

[0033] Furthermore, a hard support tube 31 is provided in the passage 30, and the inflation tube 32 passes through the hard support tube 31. The hard support tube 31 is used to provide a stable passage, which can prevent the inflation tube 32 from being deformed due to long-term pressure and improve its service life.

[0034] In addition, in this embodiment, the outer layer of the mattress body 10 is a breathable waterproof cloth filled with any one of coir, coconut shreds, hard cotton or sponge. The mattress as a whole is soft, warm and comfortable, has good moisture absorption and heat insulation, and is natural and environmentally friendly.

[0035] For further information, see Figure 1 、 Figure 2 and Figure 5 The anti-pressure sore mattress further includes a plugging pad 50 for closing the concave cavity 11. When the plugging pad 50 is filled in the concave cavity 11, the concave cavity 11 of the mattress body 10 is partially flattened, restoring the state of a normal mattress.

[0036] Specifically, the pad 50 includes a base pad portion 51 and a raised portion 52 provided on the base pad portion 51. When the pad 50 is filled in the concave cavity 11, the base pad portion 51 is located on the lower side of the annular airbag 20, and the raised portion 52 is located in the space surrounded by the innermost annular airbag 20 and remains flush with the upper surface of the mattress body 10.

[0037] In actual application, when medical staff insert the plug pad 50 into the concave cavity 11, they should deflate all the annular airbags 20 in advance so that the plug pad 50 can be smoothly placed in the concave cavity 11. After the plug pad 50 is placed in the concave cavity 11 and the position is adjusted, all the annular airbags 20 are inflated so that the bottom pad part 51 of the plug pad 50 is restricted under the annular airbag 20, ensuring that the plug pad 50 is not easy to fall out of the concave cavity 11.

[0038] In summary, the anti-pressure sore mattress in the above-mentioned embodiment of the present invention, by designing the cavity 11 on the mattress body 10, can directly provide space for the anal canal sewn at the patient's anus, thereby avoiding direct compression of the area when the patient is in bed, and can significantly reduce the risk of pressure sores.
