[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a support device for assisting patient movement, including an auxiliary support body 1, a backrest bar 2 mounted on the surface of the auxiliary support body 1, and an adjustment device 3 on the arc surface of the auxiliary support body 1. By setting the adjustment device 3, the height of the backrest bar 2 can be adjusted, avoiding the situation where the height of the backrest bar 2 is difficult to adjust and cannot be adjusted according to individual patient differences, which may lead to uneven back pressure when the patient leans on it, and cause back pain and other discomfort symptoms after prolonged use, thus affecting the patient's user experience and psychological state. This improves the practicality of the device. The arc surface of the auxiliary support body 1 is provided with a storage device 4, which can store a certain amount of items, avoiding the need for medical staff to run around to retrieve items when moving the patient, wasting time and reducing nursing efficiency, thus improving the practicality of the device.
[0030] The specific settings and functions of the adjustment device 3 and the storage device 4 will be described in detail below.
[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the adjustment device 3 includes two adjustment rods 31, both of which are fixedly connected to the surface of the auxiliary support body 1. Several circular grooves 39 are formed on the surface of each adjustment rod 31. Two fixed rods 32 are fixedly connected to the arc surface of the chair arm 2. A single-hole plate 38 is slidably connected to the arc surface of the fixed rod 32. A plug rod 33 is fixedly connected to one side of the single-hole plate 38. The arc surface of the plug rod 33 is slidably connected to the circular grooves 39. A spring 34 is fitted onto the arc surface of the fixed rod 32. The two ends of the spring 34 are fixedly connected to the chair arm 2 and the single-hole plate 38, respectively. When the operator needs to adjust the height of the chair arm 2, the operator first pulls the single-hole plate 38, causing the plug rod 33 to slide on the arc surface of the fixed rod 32. Spring 34 is stretched until the arc surface of the insertion rod 33 separates from the circular groove 39. Then, the operator pulls the fixing rod 32 to move the chair back 2 along the arc surface of the auxiliary support body 1 until the chair back 2 moves to the appropriate position. The operator can then release the single-hole plate 38. At this point, the rebound force of spring 34 causes the single-hole plate 38 to slide along the arc surface of the fixing rod 32. The single-hole plate 38 moves the insertion rod 33 until it is inserted into the circular groove 39. This improves the stability of the insertion rod 33, preventing it from loosening due to vibration or external forces. It significantly improves the stability of the fit between the insertion rod 33 and the circular groove 39, ensuring the structural reliability of the chair back 2 after height adjustment. This allows the device to assist patient movement while maintaining stability due to the chair back 33. 2. The position is stable, safer, and more effective. One end of the fixing rod 32 is fixedly connected to a circular plate 37. The size of the insert rod 33 matches the size of the circular groove 39. When the operator needs to adjust the height of the chair back 2, the operator first pulls the single-hole plate 38 and slides it on the arc surface of the fixing rod 32 until the surface of the single-hole plate 38 is in contact with the circular plate 37. At this time, the arc surface of the insert rod 33 separates from the surface of the circular groove 39. This achieves the effect of preventing damage to the spring 34 and avoids the operator pulling the single-hole plate 38 with too much force, causing the single-hole plate 38 to slide too far on the arc surface of the fixing rod 32, thus exceeding the stress range of the spring 34, causing the spring 34 to lose its elasticity and become difficult to use normally. In this situation, a square plate 35 is fixedly connected to the surface of the single-hole plate 38, and a blocking plate 36 is slidably inserted inside the square plate 35. When the staff needs to adjust the position of the chair arm 2, the staff first pulls the single-hole plate 38 to make the square plate 35 slide on the arc surface of the fixed rod 32 until the surface of the single-hole plate 38 is in contact with the round plate 37. Then the staff can push the blocking plate 36 to slide inside the square plate 35 until the surface of the blocking plate 36 is in contact with the round plate 37. At this time, the position of the insert rod 33 is restricted, so as to prevent the insert rod 33 from moving due to the influence of external force when the staff pulls the chair arm 2, which may cause the insert rod 33 to collide with the adjusting rod 31 and cause damage to the insert rod 33.
[0032] Reference Figure 4 , Figure 5 and Figure 6 As shown, specifically, the storage device 4 includes a fixed compartment 41, which is fixedly connected to the arc surface of the auxiliary support body 1. A storage compartment 42 is slidably connected inside the fixed compartment 41. Two L-shaped plates 46 are fixedly connected to the surface of the storage compartment 42, and bolts 47 are threaded into the L-shaped plates 46. Two single-sided plates 44 are fixedly connected to the surface of the storage compartment 42, and a round rod 43 is fixedly connected to the surface of the single-sided plates 44. A limit plate 45 is rotatably connected to the arc surface of the round rod 43. A torsion spring 49 is sleeved on the arc surface of the round rod 43, and the two ends of the torsion spring 49 are fixedly connected to the limit plate 45 and the round rod 43, respectively. When the operator needs to open the storage compartment 42, the operator first rotates the bolt 47 within the L-shaped plate 46 until the arc surface of the bolt 47 separates from the limit plate 45. At this time, the torque of the torsion spring 49 drives the limit plate 45 to rotate on the arc surface of the round rod 43 until the limit plate 45 no longer affects the storage compartment 42. The movement of bolt 47 automatically opens the limiting plate 45, keeping it in the open position for easy operation and reducing the number of steps required, thus improving work efficiency. The arc surface of bolt 47 is fixedly connected to an anti-detachment plate 48, whose surface is in contact with the L-shaped plate 46. When the operator needs to open the storage compartment 42, they first rotate bolt 47 to move the anti-detachment plate 48 until its surface is in contact with the L-shaped plate 46. At this point, the arc surface of bolt 47 is completely separated from the limiting plate 45, preventing bolt 47 from falling off. This avoids situations where excessive rotation of bolt 47 could cause it to separate from the L-shaped plate 46, requiring reinstallation and increasing the operator's workload.
[0033] Working principle: When the operator needs to adjust the height of the chair backrest 2, firstly, the operator pulls the single-hole plate 38, causing the insertion rod 33 to slide on the arc surface of the fixed rod 32. The spring 34 is stretched until the surface of the single-hole plate 38 is in contact with the circular plate 37. At this time, the arc surface of the insertion rod 33 separates from the surface of the circular groove 39. Then, the operator can push the blocking plate 36 to slide within the square plate 35 until the surface of the blocking plate 36 is in contact with the circular plate 37. Then, the operator pulls the fixed rod 32, causing the chair backrest 2 to slide on the arc surface of the auxiliary support body 1 until the chair backrest 2 moves to the desired height. Once the device is in the correct position, the staff can release the single-hole plate 38. At this time, the rebound force of the spring 34 causes the single-hole plate 38 to slide on the arc surface of the fixed rod 32. The single-hole plate 38 drives the insertion rod 33 to move until the insertion rod 33 is inserted into the circular groove 39, thus achieving the effect of adjusting the height of the chair back 2. This avoids the situation where the height of the chair back 2 is difficult to adjust and cannot be adjusted according to individual patient differences, which may lead to uneven pressure on the patient's back when leaning against it. Prolonged use may cause discomfort symptoms such as back pain, which may affect the patient's user experience and psychological state. This improves the practicality of the device.
[0034] When staff need to open storage compartment 42, they rotate bolt 47 to move anti-detachment plate 48 until the surface of anti-detachment plate 48 is in contact with L-shaped plate 46. At this time, the arc surface of bolt 47 is completely separated from limit plate 45. Then, the torque of torsion spring 49 drives limit plate 45 to rotate on the arc surface of round rod 43 until limit plate 45 no longer affects the movement of storage compartment 42. This achieves the effect of storing a certain amount of items, avoiding the situation where medical staff have to run around to retrieve items when moving patients, which wastes time and reduces nursing efficiency, thus improving the practicality of the device.
