Description

Technical Field

[0001] The present invention belongs to the technical field of nursing auxiliary appliances, and particularly relates to a multifunctional body position support and assisted massage turning pad. Background Art

[0002] Long-term bedridden patients are a large and special group, including the elderly who are unable to move due to various diseases and are paralyzed in bed, as well as patients who need to stay in bed for a long time for severe trauma, postoperative rehabilitation, etc. Due to the severe limitation of their physical activity ability, these patients are difficult to change their sleeping positions independently, resulting in local parts of the body being under continuous pressure for a long time. Some bony prominence parts of the human body, such as the buttocks, shoulders, heels, etc., lack sufficient muscle and fat tissue buffering. Under long-term pressure, blood circulation will be severely hindered, and insufficient blood supply will lead to local tissue hypoxia and malnutrition, and then tissue necrosis and pressure sores will occur. In order to prevent the occurrence of pressure sores, the existing turning pads have emerged. The turning pads mainly play a role in supporting the patient's body. By changing the contact part between the patient and the bed surface, the local compression time is reduced, and the risk of pressure sores is reduced to a certain extent.

[0003] However, the main function of the existing turning pads on the market is to provide basic support for patients, with relatively single functions, only meeting the basic support needs and helping them maintain a relatively stable body position when lying in bed. Although it can relieve the local pressure of the body to a certain extent, due to the lack of functions such as massage, proper massage can promote blood circulation, relieve muscle tension, and improve the body's comfort. However, the existing turning pads cannot provide massage functions, making it difficult to effectively promote blood circulation and relieve physical fatigue. Lying on the turning pad for a long time, patients are prone to feel body stiffness and soreness, with low comfort, and can only maintain a relatively static state for a long time, and the physical discomfort is difficult to be effectively relieved. Moreover, for some patients with severe illness and physical weakness, it is very difficult to complete the turning action independently only relying on the support of the turning pad, and still requires the great assistance of nursing staff. The nursing staff need to spend a lot of physical strength and energy. Although the existing turning pads can help patients change their body positions to a certain extent, for some patients with a large body weight or extremely poor physical activity ability, the nursing staff still need to spend a lot of effort to complete the turning operation. Moreover, due to the single function of the turning pad and its inability to actively assist patients in turning over, the difficulty and intensity of nursing work are increased. Summary of the Invention

[0004] The purpose of the present invention is to provide a multifunctional body position support and assisted massage turning pad to solve the problems of the existing turning pads with single functions and their inability to improve the comfort of patients and nursing efficiency.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A multi-functional body position support and assisted massage and turning-over cushion, comprising:

[0007] A main cushion, the inclined surface of the main cushion is made of elastic sponge material, the inclined surface of the main cushion is provided with anti-slip rubber strips, and a controller is arranged on one side of the main cushion;

[0008] Auxiliary cushions, the auxiliary cushions are arranged on both sides of the main cushion, a push plate is movably installed inside the auxiliary cushions, a flexible cushion layer is fixedly installed at the top of the push plate, anti-slip rubber strips are also arranged on the side of the flexible cushion layer away from the push plate, a scissor lift is fixedly installed inside the auxiliary cushions, and the movable end of the scissor lift is fixedly connected to the push plate;

[0009] A massage mechanism, the massage mechanism is arranged inside the main cushion, the massage mechanism includes a U-shaped frame fixedly installed inside the main cushion, several cams are movably installed inside the U-shaped frame, a worm gear is movably installed on one side of the U-shaped frame, the worm gear is in transmission connection with the cam, a worm is movably installed on one side of the worm gear, the worm is meshed with the worm gear, a micro servo motor is arranged inside the main cushion, and the micro servo motor is in transmission connection with the worm.

[0010] Preferably, a plurality of U-shaped frames are fixedly installed inside the main cushion, a rotating shaft is movably installed inside the U-shaped frame through bearings, several cams are fixedly installed on the outer side of the rotating shaft, and the cams are in contact with the inclined surface of the main cushion.

[0011] Preferably, worm gears are movably installed on the outer side of the U-shaped frame near the rotating shaft, the worm gears are in shaft transmission connection with the rotating shaft, worms are movably installed inside the main cushion near the worm gears, and the worms are meshed with the worm gears.

[0012] Preferably, a connecting rod is connected between the worms, a fixing plate is fixedly installed inside the main cushion near the connecting rod, a micro servo motor is installed on the fixing plate near the connecting rod through a fixing seat, and the output end of the micro servo motor is in shaft transmission connection with the connecting rod through a coupling.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The present invention provides a massage mechanism inside the main cushion. Through the coordinated operation of a rotating shaft, a cam, and a micro servo motor, regular massage of the patient's back can be achieved. When the micro servo motor drives the worm and worm gear structure to operate, the rotating shaft and the cam rotate accordingly. The cam repeatedly pushes the inclined surface area of the main cushion, continuously stimulating the back muscles and acupoints of the patient, which can promote the dilation of blood vessels in the back, increase blood flow, and improve blood circulation. More blood carries oxygen and nutrients to be transported to the back tissues and cells, helping to maintain the normal physiological functions of the body, improving local nutrient supply, and accelerating the metabolic process. For patients who are bedridden for a long time, it can effectively reduce discomfort symptoms such as muscle soreness and stiffness caused by poor blood circulation, and promote the recovery of the patient's body. By massaging the back muscles of the patient with appropriate strength and frequency, the tense muscle fibers can be relaxed and muscle spasms can be relieved.

[0015] (2) The present invention provides auxiliary cushions on both sides of the main cushion. The push plate is driven by a shear-type lifting frame to move up and down, and the patient is turned over by using the push plate and the flexible cushion layer. By simply operating the control of the lifting frame, the patient's body position can be easily changed, reducing the physical consumption of nursing staff, greatly reducing the labor intensity of nursing staff, and reducing the risk of occupational diseases such as muscle strains and lumbar disc herniation caused by frequent turning over. The combined use of the push plate and the flexible cushion layer enables the patient to feel a gentle pushing force during the turning process, avoiding physical damage caused by sudden force. The flexible cushion layer can also increase the contact area with the patient's body, disperse pressure, and improve the comfort of the patient, avoiding hard extrusion and friction on the patient's body caused by direct pushing. The movement control of the shear-type lifting frame is precise, and the nursing staff can adjust the height and strength of the push plate according to the actual situation of the patient to ensure the smoothness and accuracy of the turning operation. This structure can help them perform independent turning exercises to a certain extent. Through the guidance and support of the auxiliary mechanism, the patient can gradually adapt to the change of body position and enhance the body's coordination and balance ability.

[0031] The main pad 1, the inclined surface of the main pad 1 is made of elastic sponge material, the inclined surface of the main pad 1 is provided with an anti-slip rubber strip 11, and one side of the main pad 1 is provided with a controller 12;

[0032] The auxiliary pad 2, the auxiliary pad 2 is arranged on both sides of the main pad 1, a push plate 21 is movably installed inside the auxiliary pad 2, a flexible cushion layer 22 is fixedly installed at the top of the push plate 21, the anti-slip rubber strip 11 is also arranged on the side of the flexible cushion layer 22 away from the push plate 21, a scissor lift 23 is fixedly installed inside the auxiliary pad 2, and the movable end of the scissor lift 23 is fixedly connected to the push plate 21;

[0033] The massage mechanism 3 is arranged inside the main cushion 1. The massage mechanism 3 includes a U-shaped frame 31 fixedly installed inside the main cushion 1. A number of cams 33 are movably installed inside the U-shaped frame 31. A worm gear 34 is movably installed on one side of the U-shaped frame 31. The worm gear 34 is in transmission connection with the cam 33. A worm 35 is movably installed on one side of the worm gear 34. The worm 35 meshes with the worm gear 34. A micro servo motor 38 is arranged inside the main cushion 1. The micro servo motor 38 is in transmission connection with the worm 35.

[0034] Specifically, a number of U-shaped frames 31 are fixedly installed inside the main cushion 1. A rotating shaft 32 is movably installed inside the U-shaped frame 31 through bearings. A number of cams 33 are fixedly installed on the outer side of the rotating shaft 32. The cams 33 are in contact with the inclined surface of the main cushion 1. Worm gears 34 are movably installed on the outer side of the U-shaped frame 31 near one side of the rotating shaft 32. The worm gears 34 are in shaft transmission connection with the rotating shaft 32. Worms 35 are movably installed on the inner side of the main cushion 1 near the worm gears 34. The worms 35 mesh with the worm gears 34. A connecting rod 36 is connected between the worms 35. A fixing plate 37 is fixedly installed on the inner side of the main cushion 1 near the connecting rod 36. A micro servo motor 38 is installed on the fixing plate 37 near the connecting rod 36 through a fixing seat. The output end of the micro servo motor 38 is in transmission connection with the shaft of the connecting rod 36 through a coupling.

[0035] As can be seen from the above, when using the main cushion 1 to support the patient, the patient's back will lean against the inclined surface of the main cushion 1. The sponge material can improve the comfort level. The side parts of the main cushion 1 are all made of hard materials. At the same time, anti-slip rubber strips 11 are arranged on the inclined surface, which can effectively prevent the patient from sliding down and provide a large frictional force. The controller 12 is used to control the operation of the internal components of the device. The scissor lift 23 can push the push plate 21 to move up and down, thereby pushing the patient to turn over, enabling the patient to change the body position more easily and reducing the labor intensity of the nursing staff. The U-shaped frame 31 is used to install the rotating shaft 32. The rotating shaft 32 can drive the cam 33 to rotate. By using the cam 33 to repeatedly push against the inclined surface of the main cushion 1, the massage effect on the patient's back area can be achieved. The worm gear 34 plays a driving role. By rotating the worm gear 34, the rotating shaft 32 can be synchronously driven to rotate. The worm 35 meshes with the worm gear 34. When the worm 35 rotates, it can drive the worm gear 34 to rotate.
