Technical Field

[0001] The utility model relates to the technical field of medical air cushion beds, in particular to an anti-pressure sore adjustable medical air cushion bed. Background Art

[0002] In the field of medical care, patients who are bedridden for a long time face a significant risk of pressure sores (bedsores). Pressure sores are caused by the local tissue being under pressure for a long time, blood circulation disorders, and continuous ischemia, hypoxia, and malnutrition of the local tissue, resulting in soft tissue ulceration and necrosis. In order to effectively prevent and reduce the occurrence of pressure sores, medical air mattresses are widely used in clinical practice as an important auxiliary device.

[0003] Although traditional medical air mattresses can disperse body pressure to a certain extent, their adjustment methods are often relatively simple and cannot perform fine pressure adjustment according to the physical conditions and individual needs of different patients. In addition, for patients who need special care, such as the elderly with poor blood circulation or patients who need to recover after surgery, traditional air mattresses have limited effect in promoting blood circulation and are difficult to meet clinical needs.

[0004] With the continuous advancement of medical technology and the increasing diversification of patient needs, the market is in urgent need of a new type of medical air mattress that can be flexibly adjusted according to the patient's physical characteristics and can effectively promote blood circulation.

[0032] Embodiment 1

[0033] The air cushion bed is divided into multiple independent areas by the barrier strips between the air cushion bags. The patient can easily turn the adjustment plate 4 according to his own needs to realize the linkage mechanism of the worm 41, the worm wheel 42 and the threaded rod 43.

In addition, the built-in heating strip of the bed board 1 is evenly heated, which increases the temperature of the air inside the air cushion bag and the pressure bag, and provides a warm and comfortable rehabilitation environment for the patient.

[0034] Embodiment 2

[0035] The evenly distributed heat dissipation holes on the bed board 1 effectively solve the overheating problem that may occur during the heating process, ensuring the safety and comfort of the air mattress. In actual operation, the patient or caregiver can easily achieve personalized adjustment of the air cushion bag pressure by rotating the adjustment dial 4, which not only improves the patient's overall comfort, but also greatly reduces the risk of pressure sores caused by excessive local pressure. The ingenious combination of the heating strip and the heat dissipation holes significantly promotes the patient's blood circulation, accelerates the metabolic process, and has a positive effect on the patient's rehabilitation, demonstrating the excellent effectiveness of the utility model in humanized care and promoting patient rehabilitation.

[0036] Specifically, the air cushion bags are separated into multiple independent areas by barrier strips. Patients can realize the linkage of the worm 41, the worm wheel 42 and the threaded rod 43 by simply turning the adjustment plate 4 according to their personal needs, and then drive the threaded cylinder 44 to drive the extrusion frame to move up and down, so as to accurately squeeze the pressure bag. This process can flexibly adjust the pressure distribution of the air cushion bag to better adapt it to different parts of the patient's body, effectively avoiding the risk of pressure sores caused by excessive local pressure, and at the same time improving the overall comfort of the patient;

[0037] Furthermore, the innovative design of heating strips and heat dissipation holes has greatly promoted the patient's blood circulation. The heating strips are arranged along the length of the bed board 1, and can evenly heat the inside of the bed board 1, thereby increasing the temperature of the air inside the air cushion bag and the pressure bag. When the patient lies on such an air cushion bed, the warm environment helps to accelerate blood circulation, promote metabolism, and has a positive effect on restoring health. The heat dissipation holes on the upper surface of the bed board 1 are cleverly designed, which can promptly remove the heat inside the bed board 1 and avoid overheating, thereby ensuring the safety and comfort of the air cushion bed. This design not only embodies humanistic care, but also demonstrates the excellent effectiveness of the utility model in promoting patient rehabilitation.

[0038] Working principle:

[0039] First, the patient turns the adjustment disk 4 according to personal needs, and the worm 41, worm wheel 42 and threaded rod 43 are linked to drive the threaded cylinder 44 to drive the extrusion frame to move up and down, and accurately extrude the pressure bag to achieve pressure distribution adjustment of the air cushion bag, so that it can better adapt to different parts of the patient's body. At the same time, the heating strip embedded in the bed board 1 is evenly heated along the length direction of the bed board 1, which increases the temperature of the air inside the air cushion bag and the pressure bag, and helps to accelerate blood circulation. The heat dissipation holes on the upper surface of the bed board 1 are cleverly designed to remove the heat inside the bed board 1 in time to avoid overheating. Finally, the patient lies on such an air cushion bed and enjoys a comfortable and safe nursing experience. At this point, the entire workflow is completed.
