[0002] With the continuous development of society and the continuous improvement of technology level, for bedridden patients, turning over regularly is crucial. Especially for long-term bedridden patients, if a patient maintains a fixed posture for a long time, it is easy to cause compression of body parts, leading to the occurrence of pressure sores. Turning over the patient can relieve the body pressure, promote blood circulation, and prevent and reduce the occurrence of pressure sores.
[0003] At present, in the process of using the existing labor-saving turning assistor, due to the different thicknesses of patients' legs, the size of the leg fixing space of the existing equipment is usually fixed, and the fixation of the patient's legs may not be very stable. During turning over, the legs are likely to slip out of the equipment, resulting in poor stability during use. Moreover, after turning over is completed for some existing equipment, the supporting surface with the bed surface is small. When the patient lies on the side, the equipment may be driven by gravity and turn back to the flat position, making it inconvenient to maintain the patient's side-lying state and may require turning over the patient again, which may be rather laborious during operation. Therefore, there is an urgent need for a labor-saving turning assistor to solve the above problems. Summary of the Utility Model

[0024] Embodiment 1
[0025] As Figures 1 to 4 shown, the present utility model provides a labor-saving turning assist device, including: a main structure (one), the main structure (one) includes a base (11) and a fixed seat (12), and a groove is provided inside one end of the lower surface of the fixed seat (12). The main structure (one) is used for supporting the patient's legs. The lower end surface of the fixed seat (12) is fixedly connected to the upper surface of the base (11), and both sides of the upper surface of the fixed seat (12) are fixedly connected with connecting plates (13). T-shaped card slots are provided inside the opposite sides of the two connecting plates (13). The shape of the base (11) is a semi-cylinder, and the lower surface of the base (11) has a certain curvature. When the lower surface of the base (11) contacts the bed surface, the device can be rolled by pushing it, and this design makes the device labor-saving to use.
[0026] At both ends of the upper surface of the fixed seat 12, engaging grooves are formed inside, and the size of the engaging grooves is relatively similar to the leg size of the patient, so that the fixed seat 12 can better fix the legs of the patient and, to a certain extent, avoid the movement of the legs.
[0027] Adjusting structure 2, the adjusting structure 2 includes a threaded rod 21, and the lower end of the threaded rod 21 is connected to the inside of the middle position of the upper surface of the fixed seat 12 by a bearing. The adjusting structure 2 is used for fixing the legs of the patient. The adjusting structure 2 further includes a turntable 22, and the lower surface of the turntable 22 is fixedly connected to the upper surface of the upper end of the threaded rod 21. And a moving plate 23 is threadedly connected to the outer surface of the threaded rod 21. The lower end of the threaded rod 21 is connected to the inside of the middle position of the upper surface of the fixed seat 12 by a bearing, so that the threaded rod 21 can rotate around itself without moving. By setting the turntable 22, the threaded rod 21 can be rotated more labor-saving. When the threaded rod 21 rotates, it can drive the moving plate 23 to move up and down along the outer surface of the threaded rod 21.
[0028] T-shaped blocks are arranged at both ends of the moving plate 23, and pressing leg plates 24 are fixedly connected to both ends of the lower surface of the moving plate 23. And buffer pads are arranged on the lower surfaces of the two groups of pressing leg plates 24. The sizes of the T-shaped blocks and the T-shaped grooves are adapted to each other. This design enables the moving plate 23 to only move in the T-shaped grooves on the opposite sides of the two groups of connecting plates 13, avoiding the rotation of the moving plate 23 along with the rotation of the threaded rod 21, and at the same time preventing the moving plate 23 from detaching from the inside of the two groups of connecting plates 13.
[0029] The buffer pads arranged on the lower surfaces of the two groups of pressing leg plates 24 are made of flexible sponge. The flexible sponge is usually made of polyurethane, rubber or other elastic materials. The flexible sponge has good softness and elasticity, can effectively absorb and relieve external impact force, reduce the pressure on the human body, provide comfortable support, and the flexible sponge material usually has good air permeability, can effectively discharge the moisture and heat on the body surface, and keep dry and comfortable.
[0030] Embodiment 2
[0031] Such as Figure 5 And Figure 6As shown in the figure, this embodiment also proposes a support structure 3. The support structure 3 includes a worm 31, and the worm 31 is connected to the inside of one side surface of the base 11 by bearings. The support structure 3 is used to increase the stability of the device. The support structure 3 also includes a worm gear 32, and the lower end of the worm gear 32 is connected to the inside of the base 11 by bearings. And the outer surface of the worm gear 32 is meshed with the outer surface of one end of the worm 31. The upper end of the worm gear 32 is fixedly connected with a gear 33, and the outer surface of the gear 33 is meshed with a first rack 34. And one end of the first rack 34 is fixedly connected with a first support plate 35. The first rack 34 is inserted into the groove inside the fixed seat 12. The worm 31 is connected to the inside of one side surface of the base 11 by bearings, so that the worm 31 can only rotate and cannot move, improving the stability during use. When the worm 31 rotates, it can drive the worm gear 32 to rotate. The lower end of the worm gear 32 is connected to the inside of the base 11 by bearings, making the rotation of the worm gear 32 more stable. When the worm gear 32 rotates, it can drive the gear 33 to rotate synchronously. When the gear 33 rotates, it can drive the gear 33 to move outwards inside the groove of the fixed seat 12, and at the same time drive the first support plate 35 to move outwards, so that the distance between the first support plate 35 and a set of connecting plates 13 is enlarged, increasing the support surface with the bed surface.
[0032] The outer surface of the gear 33 is meshed with a second rack 36, and one end of the second rack 36 is fixedly connected with a second support plate 37. And the second rack 36 is inserted into the groove inside the fixed seat 12. When the gear 33 rotates, it can also drive the second rack 36 to move outwards inside the groove of the fixed seat 12, and at the same time drive the second support plate 37 to move synchronously, expanding the distance between the second support plate 37 and a set of connecting plates 13, further increasing the support surface with the bed surface. This design makes the support area between the device and the bed surface larger, thereby improving the stability of the device.
[0033] Working principle: When the device is in use, the device is placed on the bed surface through the base 11, and the legs of the patient are respectively placed inside the engaging grooves opened in the fixed seat 12. According to the thickness of the patient's legs, rotate the turntable 22 to drive the threaded rod 21 to rotate around its own center, driving the moving plate 23 to move downwards along the outer surface of the threaded rod 21, so that the lower surfaces of the two leg pressing plates 24 are in contact with the patient's legs. At this time, the device is fixed to the patient's legs;
[0034] The rotating worm 31 drives the worm wheel 32 to rotate. When the worm wheel 32 rotates, it drives the gear 33 to rotate synchronously. When the gear 33 rotates, it drives the first rack 34 and the second rack 36 to move inwards respectively inside the groove of the fixed seat 12, and synchronously drives the first support plate 35 and the second support plate 37 to move synchronously, so that the distance between the first support plate 35 and the second support plate 37 and a group of connecting plates 13 is enlarged, and the supporting surface between the device and the bed surface is increased. Push the patient's body and the device with both hands at the same time to stand the patient and the device at a right angle on the bed surface. At this time, the patient lies on the side and the back does not contact the bed surface. Then, the patient can be cleaned or cared for. The above is the entire working principle of this utility model.
