Description

Technical Field

[0001] This utility model relates to the field of health care technology, and in particular to an anti-bedsore massage mat for use in nursing beds. Background Technology

[0002] Currently, patients suffer from injuries (such as sequelae of cerebral hemorrhage and stroke, hemiplegia or total paralysis, limb sprains or even fractures) that affect normal limb movement and require long-term bed rest. They have to eat, drink and relieve themselves in bed. For patients, the inconvenience of movement leads to the pollution of their body and environment by urine and feces. Over time, this can easily lead to bedsores and other secondary illnesses, causing great caregiving pain for their families.

[0003] Vertical pressure and localized moisture are the main causes of bedsores in patients or the elderly who are bedridden for extended periods. Anti-bedsore air mattresses are currently available on the market. These typically consist of multiple air chambers made of soft, durable materials. When a patient lies on the mattress, the air chambers are compressed by the body's pressure, providing even support. This even pressure distribution effectively reduces pressure on the patient's body and lowers the risk of bedsores. However, the complex structure of these anti-bedsore air mattresses can lead to less than ideal anti-bedsore performance in practical applications. Utility Model Content

[0031] Please see Figures 1 to 4 As shown, this embodiment provides an anti-decubitus massage pad for a nursing bed, which includes a base pad body 10 and multiple rows of massage columns 20. The base pad body 10 is configured to be laid flat on the nursing bed. An airflow channel 11 is provided inside the base pad body 10, and an air inlet 12 is provided on the base pad body 10. The top surface of the base pad body 10 is arranged along a first horizontal direction ( Figure 1 Several rows of first vent holes 13 are arranged at intervals in the middle x direction. The first end of the airflow channel 11 is connected to the air inlet 12, and the second end of the airflow channel 11 is connected to all the first vent holes 13. Each row of first vent holes 13 includes a second horizontal direction ( Figure 2 Multiple first vent holes 13 are spaced apart in the middle (y direction), and air inlets 12 are connected to an external air supply component, which is configured to supply gas to the airflow channel 11; multiple rows of massage columns 20 are spaced apart in the first horizontal direction, and each row of massage columns 20 includes multiple massage columns 20 spaced apart in the second horizontal direction, and the massage columns 20 are detachably installed on the top surface of the base pad body 10.

[0032] It is evident that the physical contact of the multiple massage columns 20 disperses the local pressure on the patient, avoiding blood circulation disorders caused by long-term pressure; the airflow channel 11 sprays gas through the first vent 13, which keeps the skin dry on the one hand, and the airflow impact can assist massage and promote local blood circulation on the other hand, thus enhancing the effect of preventing bedsores.

[0033] In one embodiment, the base body 10 includes a base 14 and a cover plate 15. The cover plate 15 is detachably and sealed on the base 14 by a connecting assembly, and an airflow channel 11 is formed between the cover plate 15 and the base 14.

[0034] Specifically, the top perimeter of the cover plate 15 is chamfered.

[0035] As can be seen, the cover plate 15 and the base 14 are detachable, which facilitates the cleaning and maintenance of the airflow channel 11, avoids the accumulation of dirt and the growth of bacteria, ensures smooth airflow, and guarantees the stability of the anti-bedsore function.

[0036] In one implementation, the connecting components are connected by thread and snap-fit, and a sealing ring is provided between the cover plate 15 and the base 14.

[0037] Specifically, the base 14 has multiple mounting holes, and the cover plate 15 has threaded holes corresponding to the mounting holes. The fixing bolts pass through the mounting holes and are threaded into the threaded holes to fix the cover plate 15 onto the base 14.

[0038] Specifically, the mounting hole is provided with a limit groove, and the threaded hole is provided with a limit block corresponding to the limit groove.

[0039] As can be seen, the combination of threaded connection and snap-fit ​​not only ensures the firm fixation of cover plate 15 and base 14, but also facilitates quick assembly and disassembly; the sealing ring further enhances the sealing performance, reduces gas leakage, ensures stable airflow pressure, and improves ventilation effect.

[0040] In one embodiment, the massage column 20 includes a head 21, a shoulder 22, and a connecting part 23. Both the head 21 and the shoulder 22 are cylindrical structures. The two ends of the shoulder 22 are connected to the head 21 and the connecting part 23, respectively. The outer diameter of the shoulder 22 is smaller than the outer diameter of the head 21. The connecting part 23 is umbrella-shaped. The outer diameter of the connecting part 23 is larger than the outer diameter of the shoulder 22 and smaller than the outer diameter of the head 21.

[0041] As can be seen, the head 21 has a larger outer diameter, providing sufficient support area to distribute pressure; the shoulder 22 has a smaller outer diameter, which can produce a certain elastic deformation when under pressure, buffering pressure impact and improving comfort; the umbrella-shaped connecting part 23 ensures a stable connection between the massage column 20 and the base pad, preventing it from falling off during use. At the same time, the outer diameter of the connecting part 23 is between the shoulder 22 and the head 21, which can limit the massage column 20 from being inserted too deeply into the base pad.

[0042] In one embodiment, the base pad body 10 and the multiple massage columns 20 are separate structures. The top surface of the base pad body 10 is provided with multiple assembly holes 16. The assembly holes 16 are provided with receiving holes 17. The outer diameter of the connecting part 23 is larger than the diameter of the assembly hole 16 and smaller than or equal to the diameter of the receiving hole 17. The connecting part 23 is inserted into and engaged in the receiving hole 17 along the opening direction of the assembly hole 16. One connecting part 23 corresponds to one assembly hole 16.

[0043] As can be seen, the split structure allows the massage column 20 to be replaced individually, reducing maintenance costs; the assembly hole 16 and the receiving hole 17, together with the umbrella-shaped connecting part 23, form a reliable snap-fit ​​structure, making installation and disassembly convenient.

[0044] In one embodiment, the head 21 is generally polygonal, elliptical or circular, and the supporting surface of the head 21 is an arc surface or a plane.

[0045] As can be seen, the head 21 can be designed with a variety of shapes and support surfaces. The rounded surface can reduce local pressure, while the flat surface provides more stable support, improving comfort in different scenarios.

[0046] In one implementation, the supporting surface of the head 21 is polygonal, arc-shaped, or circular.

[0047] In one embodiment, a toilet is provided in the middle of the nursing bed, and an avoidance hole 18 is provided in the middle of the base body 10. The shape of the avoidance hole 18 is consistent with the shape of the opening of the toilet.

[0048] As can be seen, the 18-hole design allows the commode to be adapted to the nursing bed, eliminating the need for patients to remove the entire massage pad when using the commode, reducing nursing procedures and avoiding discomfort or risks caused by frequent patient movement. It is especially suitable for long-term bedridden patients with limited mobility.

[0049] In one embodiment, a plurality of second vent holes 19 are provided at intervals around the avoidance hole 18 on the base pad body 10, and the second vent holes 19 are connected to the airflow channel 11.

[0050] Specifically, the edge of the clearance hole 18 is provided with an arc surface, and the second vent hole 19 is opened on the arc surface.

[0051] As can be seen, the second vent 19 around the avoidance hole 18 can spray air onto the skin around the toilet, keeping the area dry and preventing local bedsores or infections.

[0052] As one implementation method, the gas is any one of heating, cooling, room temperature gas, or functional gas with disinfection and sterilization effects.

[0053] Specifically, functional gases with disinfection and sterilization effects can be obtained by connecting to a solvent with disinfection and sterilization effects through an external gas supply component, or by using a pre-made functional gas with disinfection and sterilization effects.

[0054] As can be seen, the gas types are diverse. Heating gas can keep warm in low-temperature environments, while cooling gas can cool down in high-temperature environments, improving the patient's comfort. Disinfecting and sterilizing gas can reduce the growth of bacteria on the surface of the mat and in contact with the skin, reducing the risk of infection and making it widely applicable.

[0055] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0056] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
