Description

Technical Field

[0001] The present invention relates to the technical field of nursing equipment, and in particular to an intelligent nursing bed. Background Art

[0002] Nursing beds are medical devices designed specifically for patients with limited mobility or long-term bedridden patients. They integrate multiple functions to meet the basic living needs of patients and aim to provide comfortable and convenient nursing services to improve the quality of life of patients. Nursing beds usually have functions such as automatic lifting, back lifting, leg lifting, left and right turning, and bedpans, which can meet the personalized needs of different patients, such as convenient getting in and out of bed, adjusting posture, promoting blood circulation, reducing discomfort and complications caused by long-term bed rest, etc., thereby improving the quality of life of patients.

[0003] For patients who have partially lost their muscle strength or cannot take care of themselves completely, the quilt will shift due to some of their hand or leg movements, so that the quilt cannot cover the patient's chest or back. However, these patients do not have the ability to cover themselves with the quilt. This requires nursing staff to frequently check the patient's condition and cover the patient with the quilt to avoid the risk of causing the patient to catch a cold and cause related complications. However, this increases the labor intensity of nursing staff, and nursing staff are not always able to promptly detect the displacement of the quilt and re-seal the quilt on the patient in a timely manner.

[0052] Such as Figures 1 to 3As shown in the figure, this embodiment provides an intelligent nursing bed, which includes a bed body 1 and a quilt covering mechanism 2 arranged on the bed body 1. The quilt covering mechanism 2 is used to pull out the quilt 21 and cover it on the patient, as well as to store the quilt 21.

[0053] The quilt covering mechanism 2 includes a quilt 21, a driving mechanism 22, two traction devices 23 arranged on both sides of the bed body 1, and a storage box 24 arranged at the tail of the bed body 1; both of the two traction devices 23 are connected to the storage box 24, and a traction mechanism that can move back and forth along its length is provided on the traction device 23; a rotatable support rotating shaft 241 is arranged in the storage box 24, and the driving mechanism 22 is used to drive the support rotating shaft 241 to rotate to control the movement of the traction mechanism on the traction device 23. Bearings are arranged at both ends of the support rotating shaft 241, and installation sleeves corresponding to the connection of the support rotating shaft 241 are arranged in the storage box 24. Both ends of the support rotating shaft 241 are rotationally connected to the corresponding installation sleeves in the storage box 24 through bearings.

[0054] Both ends of the tail of the quilt 21 are connected to the support rotating shaft 241 through cloth belts 242, and both ends of the head of the quilt 21 are respectively connected to the traction mechanisms on the corresponding traction devices 23 through pull ropes 211. The traction mechanism is used to pull the quilt 21 coiled on the support rotating shaft 241 towards the head of the bed body 1 and cover it on the bed body 1.

[0055] In this technical solution, by arranging the traction devices 23 on both sides of the bed body 1, the traction mechanisms of the traction devices 23 are controlled to pull the quilt 21 coiled on the support rotating shaft 241 towards the head of the bed body 1 and cover it on the patient on the bed body 1. Since the four corners of the quilt 21 are respectively connected to the traction mechanism and to the support rotating shaft 241 through the cloth belt 242, even if the patient makes partial limb movements with their hands or legs, the quilt 21 will not shift, thus ensuring that the quilt 21 can effectively cover the patient's chest or back, and at the same time reducing the labor intensity of the nursing staff.

[0056] As Figures 4 to 7 As shown in the figure, the traction mechanism includes a slide rail 231 arranged in the traction device 23, a sliding sleeve 232 slidably matched with the slide rail 231, an auxiliary lifting plate 233 connected to the sliding sleeve 232, a traction assembly 234, and an actuator 235. A guiding groove 2311 is arranged along the length direction of the slide rail 231. A longitudinal plate 236 extending downward is arranged on the side of the slide rail 231 close to the head of the bed body 1. A vertical hole 2361 arranged vertically is arranged in the longitudinal plate 236. The end of the guiding groove 2311 close to the head of the bed body 1 is communicated with the upper end of the vertical hole 2361. The auxiliary lifting plate 233 is arranged in parallel with the longitudinal plate 236, and the auxiliary lifting plate 233 is provided with an obliquely arranged kidney-shaped hole 2331, and the upper end of the kidney-shaped hole 2331 is inclined towards the head of the bed body 1.

[0057] As Figure 8As shown, the traction assembly 234 includes a guiding rectangular block 2341, a guiding column 2342 coaxially and centrally connected to the guiding rectangular block 2341, and a traction portion 2343 connected to the guiding column 2342. The traction portion 2343 is connected to the head of the quilt 21 through a drawstring 211. The guiding rectangular block 2341 is slidably fitted in the guiding groove 2311, and the guiding column 2342 is slidably fitted in the kidney-shaped hole 2331. The actuator 235 controls the sliding sleeve 232 to move back and forth along the length direction of the slide rail 231 on the slide rail 231 through the driving mechanism 22 and the support rotating shaft 241. In an embodiment, the mating end of the sliding sleeve 232 and the slide rail 231 is provided with a through dovetail groove, and the upper end of the slide rail 231 is dovetail-shaped along its length direction. The sliding sleeve 232 is slidably fitted on the slide rail 231, which can effectively avoid the phenomenon that the sliding sleeve 232 disengages from the slide rail 231.

[0058] When the actuator 235 drives the sliding sleeve 232 to move from the tail of the bed body 1 to the head of the bed body 1, the guiding rectangular block 2341 is slidably fitted in the guiding groove 2311, and the guiding column 2342 is slidably fitted at the upper end of the kidney-shaped hole 2331; when the actuator 235 drives the sliding sleeve 232 to move to one end of the guiding groove 2311 close to the head of the bed body 1, as the sliding sleeve 232 drives the auxiliary lifting plate 233 to continue moving in this direction, the inclined kidney-shaped hole 2331 on the auxiliary lifting plate 233 presses down the guiding column 2342, so that the guiding rectangular block 2341 moves downward along the vertical hole 2361 until it moves to the lower end of the kidney-shaped hole 2331; so as to realize that the traction portion 2343 pulls the quilt 21 coiled on the support rotating shaft 241 to the head of the bed body 1 and covers the patient on the bed body 1. When the actuator 235 drives the sliding sleeve 232 to move from the head of the bed body 1 to the tail of the bed body 1, the inclined kidney-shaped hole 2331 on the auxiliary lifting plate 233 lifts the guiding column 2342, so that the guiding rectangular block 2341 moves upward along the vertical hole 2361 until it moves to the upper end of the kidney-shaped hole 2331, and the guiding rectangular block 2341 is located in the guiding groove 2311. Then the traction assembly 234 follows the auxiliary lifting plate 233 and the sliding sleeve 232 to move to the tail of the bed body 1, and the support rotating shaft 241 rotates reversely to re-coil the quilt 21 on the support rotating shaft 241, realizing the storage of the quilt 21.

[0059] Specifically, the slide rail 231 is arranged obliquely within the traction device 23, that is, the horizontal height of the end of the slide rail 231 close to the head of the bed body is higher than the horizontal height of the end of the slide rail 231 close to the tail of the bed body. This enables the traction assembly 234 to gradually lift the quilt 21 when pulling the quilt 21; then, under the action of the auxiliary lifting plate 233, the longitudinal plate 236, and the traction assembly 234, the quilt 21 is pulled downward to cover the patient on the bed body 1. Another advantage is that the storage box 24 can set the quilt outlet 244 on the side close to the mattress on the bed body 1, which facilitates the tail of the quilt 21 to cover the patient's feet and avoids the situation of the patient's feet getting cold.

[0060] To facilitate controlling the reciprocating movement of the traction mechanism on the traction device 23 by rotating the support rotating shaft 241, the actuator 235 includes a first pulley 2351, a second pulley 2352, and a traction belt 2353. The first pulley 2351 is rotatably connected to the end of the traction device 23 close to the head of the bed body 1. The second pulley 2352 is sleeved on one end of the support rotating shaft 241. The traction belt 2353 is sleeved on the first pulley 2351 and the second pulley 2352; and a connecting member 2354 fixedly connected to the sliding sleeve 232 is provided on the traction belt 2353. A support shaft is provided at the installation position of the first pulley 2351 on the traction device 23, and the first pulley 2351 is rotatably connected to the support shaft through a bearing. When the support rotating shaft 241 rotates, it drives the second pulley 2352 to rotate. The second pulley 2352 drives the first pulley 2351 to rotate through the traction belt 2353. At this time, the connecting member 2354 on the traction belt 2353 moves along with the traction belt 2353. By driving the forward or reverse rotation of the support rotating shaft 241, the reciprocating movement of the connecting member 2354 within the traction device 23 can be controlled. It should be noted that the movement trajectory of the connecting member 2354 is parallel to the movement trajectory of the sliding sleeve 232, so as to facilitate the connecting member 2354 to drive the sliding sleeve 232 to move on the slide rail 231.

[0061] In one embodiment, the guide groove 2311 penetrates through the wall thickness of the slide rail 231. A first limit disk 2345 is provided at one end of the guide rectangular block 2341 away from the guide post 2342. A second limit disk 2346 is provided between the guide post 2342 and the traction portion 2343. A path matching hole 237 is provided along the movement trajectory of the traction assembly 234 on the side of the traction device 23 close to the bed body 1, and the path matching hole 237 is movably matched with the second limit disk 2346. The designs of the first limit disk 2345 and the second limit disk 2346 restrict the movement of the guide rectangular block 2341 within the guide groove 2311 or the vertical hole 2361, and restrict the movement of the guide post 2342 within the kidney-shaped hole 2331 of the auxiliary lifting plate 233, effectively avoiding the phenomenon of the guide rectangular block 2341 or the guide post 2342 derailing.

[0062] In order to facilitate the traction part 2343 to cover the quilt 21 on the patient on the bed 1, the traction part 2343 includes a fixing part 2347 connected to the second limiting plate 2346 and a traction rod 2348 connected to the fixing part 2347, and the lower end of the traction rod 2348 is connected to the corresponding part of the head of the quilt 21 through the pull rope 211. Secondly, the lower end of the traction rod 2348 is provided with an annular groove 2349, and the pull rope 211 is sleeved in the annular groove 2349 to prevent the pull rope 211 from falling off. In addition, the fixing part 2347 is provided with a longitudinally through threaded hole, and the upper part of the traction rod 2348 is threadedly connected to the threaded hole of the fixing part 2347, so as to facilitate the adjustment of the relative position of the traction rod 2348 and the fixing part 2347, so as to ensure that the quilt 21 pulled out by the traction rod 2348 is effectively covered on the patient.

[0063] In order to store the traction part 2343, a concave shell 243 is provided on the side of the storage box 24 close to the bed body 1, and a quilt outlet 244 is provided in the concave shell 243. The end of the slide rail 231 away from the head of the bed body 1 is located in the storage box 24, and the traction assembly 234 passes through the corresponding side wall of the concave shell 243 along the path of movement of the slide rail 231; when the sliding sleeve 232 moves to the end of the slide rail 231 away from the head of the bed body 1, the traction part 2343 is located in the concave shell 243. At the same time, in order to facilitate the quilt 21 to be pulled out from the quilt outlet 244, a guide rod 246 arranged parallel to the length direction of the quilt outlet 244 is provided in the traction device 23.

[0064] In one embodiment, a partition 245 is provided in the storage box 24, and the partition 245 divides the interior of the storage box 24 into an upper chamber and a lower chamber, and the support shaft 241 is arranged in the upper chamber; the driving mechanism 22 includes a driving motor 221, a driving wheel 222, a driven wheel and a front transmission belt 223, the driving motor 221 is installed at one end of the lower chamber, the shaft of the driving motor 221 is connected to the driving wheel 222, the driven wheel is sleeved on the support shaft 241, and the front transmission belt 223 is sleeved on the driving wheel 222 and the driven wheel. A clearance hole is provided on the partition 245 corresponding to the front transmission belt 223, so that the front transmission belt 223 can pass through the partition 245. The driving motor 221 drives the support shaft 241 to rotate through the driving wheel 222, the driven wheel and the front transmission belt 223.

[0065] In addition, in order to facilitate the replacement of the quilt 21, the quilt 21 and the cloth belt 242 can be connected by Velcro; that is, Velcro is set at the corresponding connection between the quilt 21 and the cloth belt 242, and corresponding Velcro is also set on the cloth belt 242, so that disassembly can be convenient.

[0066] In one embodiment, the intelligent nursing bed further includes a tail electric push rod disposed at the tail of the bed body 1 and two side electric push rods respectively disposed on both sides of the bed body 1; the telescopic end of the tail electric push rod is hinged to the bottom of the storage box body 24, and the telescopic ends of the two side electric push rods are respectively hinged to the bottoms of the corresponding traction devices 23. The tail electric push rod and the two side electric push rods are not shown in the figure and belong to the prior art, so they will not be elaborated here. By the action of the tail electric push rod and the two side electric push rods, the storage box body 24 and the traction device 23 can be driven to rise or fall. The stroke of the tail electric push rod can be the same as or different from the stroke of the side electric push rod; the strokes of the two side electric push rods are kept the same; in this way, the quilt covering mechanism 2 can be made parallel or inclined relative to the bed body 1 to adapt to various use environments.
