Description

Technical Field

[0001] This utility model relates to the field of nursing equipment technology, and more specifically, to a nursing bed. Background Technology

[0002] Traditional nursing equipment such as bedpans, turning mats, and anti-decubitus air mattresses can assist in basic nursing procedures, but they generally suffer from limited functionality, insufficient comfort, and low automation. For example, disposable bedpans are mostly made of hard plastic, which can easily cause pressure sores on the patient's skin with long-term use; while manually operated turning aids rely on the physical strength of caregivers and are difficult to use for precise position adjustment.

[0003] In recent years, nursing bed technology has continuously developed, gradually evolving from basic mechanical adjustments to intelligent and multifunctional designs. Modern nursing beds typically employ electric drive systems, using control panels or remote controls to adjust functions such as backrest height, leg flexion / extension, and overall height, providing patients with comfortable positional support. While improvements have been made in turning over, pressure ulcer prevention, and rehabilitation, daily bowel and bladder issues often pose a double burden for both patients and caregivers. Patients have limited mobility, requiring caregivers to assist them while simultaneously retrieving the bedpan, and afterwards, handling waste and cleaning the bedpan. Therefore, there is an urgent need for a nursing bed integrating an intelligent commode, reducing the workload of caregivers, and offering a simple, reliable structure that is easy for caregivers to operate. Utility Model Content

[0004] In view of this, the present invention provides a nursing bed that can meet the excretion needs of bedridden patients and is convenient for nursing staff to operate.

[0005] An exemplary embodiment of this utility model provides a nursing bed, including a bed frame and a bed board, the bed board being mounted on the bed frame and having an opening. The nursing bed further includes: a drive unit mounted on the bed frame; a toilet seat disposed below the bed board and configured to move under the drive unit, having a first state in which the toilet seat opening is disengaged from the opening, and a second state in which the toilet seat opening is aligned with the opening for use; a driven unit connected to the drive unit; and a cover plate connected to the driven unit, the driven unit being configured to move the cover plate under the drive unit, such that the cover plate closes the opening in response to the toilet seat being in the first state, and opens the opening in response to the toilet seat moving toward the opening.

[0006] According to an embodiment of the present invention, a sealing cover is also included, disposed below the bed board, which is suitable for sealing the toilet opening when the toilet is in the first state.

[0007] According to an embodiment of the present invention, the driving part includes: a driving member; a guide member configured to guide the toilet to move along an arc trajectory in a vertical plane under the drive of the driving member, so that the toilet can switch between the first state and the second state.

[0008] According to an embodiment of the present invention, the guide member includes: a plurality of parallel guide rods, the first end of each of the guide rods being rotatably connected to the bed frame; a support frame, rotatably connected to the second end of each of the guide rods to be suspended below the bed frame and kept parallel to the bed frame, and the toilet is arranged on the support frame.

[0009] According to an embodiment of the present invention, the two ends of the drive member are rotatably connected to the support frame and the bed frame, respectively, and are configured to extend or shorten to drive the support frame to carry the toilet along the arc trajectory under the guidance of the guide rod.

[0010] According to an embodiment of the present invention, one end of the cover plate is mounted on the bed board via a pivot, and the other end is used as an opening and closing end, which is suitable for rotating around the pivot under the drive of the driven part to avoid the toilet and close or open the opening.

[0011] According to an embodiment of the present invention, the driven part includes: a first rod extending downward from the lower surface of the cover plate; and a second rod, the two ends of which are rotatably connected to the first rod and the support frame, respectively, so that under the drive of the support frame, the first rod moves horizontally, and the first rod moves vertically simultaneously under the restriction of the rotating shaft, so that the opening and closing end rotates around the rotating shaft.

[0012] According to an embodiment of the present invention, the driven part further includes a third rod extending upward from the upper surface of the support frame. The first end of the second rod is rotatably connected to the first rod, and the second end of the second rod is rotatably connected to the third rod, so as to rotate relative to the support frame.

[0013] According to an embodiment of the present invention, the first rod and the third rod overlap at least partially in the vertical direction, so that the second end of the second rod is higher than the first end in the vertical direction.

[0014] According to an embodiment of the present invention, the bed board includes: a horizontal part, which is laid on the bed frame; and a movable part, which is rotatably connected to the horizontal part and has a horizontal state parallel to the horizontal part and an inclined state that maintains a preset angle with the horizontal part.

[0048] Figure 1 This is a three-dimensional structural diagram of the nursing bed provided by an exemplary embodiment of the present invention. Figure 2 This is a plan view of the commode seat of the nursing bed provided in an exemplary embodiment of the present invention in a first state. Figure 3 This is a plan view of the commode seat of the nursing bed provided in an exemplary embodiment of the present invention in a second state.

[0049] An exemplary embodiment of this utility model provides a nursing bed, such as... Figures 1-3 As shown, the bed includes a bed frame 5 and a bed board 6. The bed board 6 is mounted on the bed frame 5 and has an opening 61. The nursing bed also includes a drive unit 1, a toilet 2, a driven unit 3, and a cover 4. The drive unit 1 is mounted on the bed frame 5. The toilet 2 is located below the bed board 6 and is configured to move under the drive unit 1, having a first state where the toilet opening 21 is disengaged from the opening 61, and a second state where the toilet opening 21 is aligned with the opening 61 for use. The driven unit 3 is connected to the drive unit 1, and the cover 4 is connected to the driven unit 3. The driven unit 3 is configured to move the cover 4 under the drive unit 1, so that the cover 4 closes the opening 61 in response to the toilet 2 being in the first state, and opens the opening 61 in response to the toilet 2 moving towards the opening 61.

[0050] In this embodiment, the bed board 6 is installed above the bed frame 5, and the bed frame 5 has a receiving space below it. The commode 2 is located in this receiving space and can be moved by the drive unit 1. When the nursing bed is not in use, the commode 2 is in a first state away from the opening 61, the commode opening 21 is disengaged from the opening 61, and the cover plate 4 covers the opening 61 to improve the flatness of the bed board 6 for the patient to sit or lie down. At this time, the commode opening 21 of the commode 2 is covered by the bed board 6 or other components. When the nursing bed is in use, the commode 2 switches to a second state under the drive unit 1, that is, it moves towards the opening 61 until the commode opening 21 is aligned with the opening 61. At the same time, the cover plate 4 is linked with the commode 2 through the driven part 3 to open the opening 61 for the patient to use. In this way, the linkage between the commode 2 and the cover plate 4 is realized through the drive unit 1 and the driven part 3, which makes it easier for bedridden patients to meet their excretion needs and also reduces the workload of nursing staff.

[0051] It should be noted that in the above embodiments, in the second state of the toilet 2, the lid 4 opens the opening 61, and the toilet seat opening 21 and the opening 61 are roughly aligned for use. The alignment precision of the toilet seat opening 21 and the opening 61 is not specifically limited. Preferably, the toilet seat opening 21 and the opening 61 are approximately equal in size and located on the same axis. In some other embodiments, the toilet seat opening 21 may be slightly larger than the opening 61 to prevent excrement from splashing out and to reduce the decrease in comfort of the bed board 6 caused by the opening 61.

[0052] In one exemplary embodiment, such as Figure 3 As shown, the above-mentioned nursing bed also includes a sealing cover 7, which is located below the bed board 6 and is suitable for sealing the toilet opening 21 when the toilet 2 is in the first state.

[0053] In this implementation, when the toilet 2 is in the first state, the toilet 2 is located below the bed board 6 and away from the opening 61 (this position of the toilet 2 can be called the initial position), and the toilet opening 21 is sealed by the sealing cover 7. Similarly, when the toilet 2 switches from the second state back to the first state, and the toilet 2 moves back to the initial position from below the opening 61, the sealing cover 7 can just seal the toilet opening 21 to prevent odors from escaping.

[0054] For example, the sealing cover 7 and the bed frame 5 are preferably detachable by means of bolts and nuts, or can be fixedly connected by means of welding.

[0055] In one exemplary embodiment, such as Figures 1-3 As shown, the drive unit 1 includes a drive member 11 and a guide member 12. The guide member 12 is configured to guide the toilet 2 to move along an arc trajectory in a vertical plane under the drive of the drive member 11, so that the toilet 2 switches between a first state and a second state.

[0056] In this embodiment, the toilet seat 2 is arranged on the guide member 12 and moves synchronously with the guide member 12. Driven by the drive member 11, the toilet seat 2 moves from the initial position along an arc trajectory, that is, while moving horizontally, it first moves downward and then upward until the toilet seat opening 21 is aligned with the opening 61, and the front end of the toilet seat 2 passes through the opening 61 to the top of the bed board 6, thereby preventing excrement from splashing out. After use, the drive member 11 drives the toilet seat 2 back to the initial position along the arc trajectory and seals with the sealing cover 7. This reduces the complexity of the overall structure and production cost. The removal, return, and locking of the toilet seat 2 (sealing cover 7) can be achieved by the drive member 11 alone, avoiding the problems of cumbersome structure and many working steps caused by relying on multiple drive bodies.

[0057] It should be noted that, taking the structure of a common toilet in the prior art as an example, the end of the toilet 2 with a water tank or flushing control mechanism is the rear end, and the opposite end is the front end. The front end is higher than the rear end. When the toilet 2 is in the second state, the front end passes through the opening 61 from under the bed board 6 to above the bed board 6 to avoid excrement splashing out.

[0058] Figure 4 This is a perspective view of the nursing bed after removing the drive component, provided by an exemplary embodiment of this utility model. Figure 5 This is a perspective view of the nursing bed provided by an exemplary embodiment of the present invention, after removing the toilet seat and drive unit. Figure 6 This is a three-dimensional structural diagram of the guide component of the nursing bed provided in an exemplary embodiment of this utility model.

[0059] According to embodiments of this disclosure, such as Figures 4-6 As shown, the guide member 12 includes a plurality of parallel guide rods 121 and a support frame 122. The first end of each guide rod 121 is rotatably connected to the bed frame 5, and the support frame 122 is rotatably connected to the second end of each guide rod 121 to be suspended below the bed frame 5 and kept parallel to the bed frame 5. The toilet 2 is arranged on the support frame 122.

[0060] In this implementation, multiple guide rods 121 are of equal length and parallel to each other, and the second end of each guide rod 121 can rotate around its first end. The support frame 122 supports the toilet seat 2. Taking two guide rods 121 as an example, the two guide rods 121, the bed frame 5, and the support frame 122 form a parallelogram. Since the bed frame 5 is placed on the ground and remains stationary, when the drive member 11 drives the support frame 122, the support frame 122 can move along an arc trajectory with the bed frame 5 as the center and the guide rods 121 as the radius. Simultaneously, because the multiple guide rods 121 are of equal length, the support frame 122 can always remain parallel to the bed frame 5 and will not tilt during movement.

[0061] For example, the support frame 122 can be a rectangular frame or a rectangular plate for arranging the toilet 2. Based on this, the guide rods 121 are preferably four in number, respectively located at the four vertices of the rectangular frame / rectangular plate to improve structural stability.

[0062] In some other embodiments, a guide rod 121 may be provided at the midpoint of each of the two longer sides of the rectangular frame / rectangular plate.

[0063] Further according to embodiments of this disclosure, such as Figures 1-6As shown, the two ends of the drive member 11 are rotatably connected to the support frame 122 and the bed frame 5 respectively, and are configured to extend or shorten to drive the support frame 122 to carry the toilet 2 to move along an arc trajectory under the guidance of the guide rod 121.

[0064] In this embodiment, the drive member 11 drives the support frame 122 by telescopic movement. Since the support frame 122 is restricted by the guide rod 121 to move along an arc trajectory, the drive member 11 is simultaneously rotatably connected to the bed frame 5 so that it tilts at different angles during the process of driving the support frame 122, that is, it rotates around the connection point with the bed frame 5.

[0065] Furthermore, in the vertical direction, the height of the connection point between the drive member 11 and the support frame 122 is preferably higher than the height of the connection point between the drive member 11 and the bed frame 5.

[0066] For example, the drive component 11 may include, but is not limited to, an electric push rod, as long as it is a drive component with telescopic and locking functions.

[0067] In one exemplary embodiment, such as Figures 1-5 As shown, one end of the cover plate 4 is mounted on the bed board 6 via a pivot, and the other end is used as an opening and closing end. It is suitable for rotating around the pivot under the drive of the driven part 3 to avoid the toilet 2 and close or open the opening 61.

[0068] In this embodiment, the lid 4 opens and closes the opening 61 by rotating around a pivot, and the opening and closing ends of the lid 4 can avoid the toilet bowl 2 during rotation. That is, the toilet bowl 2 and the lid 4 will not interfere with each other during the linkage process. For example, by appropriately adjusting the size of the toilet bowl 2 or the lid 4, it can be ensured that they do not interfere with each other when they are linked.

[0069] In some other embodiments, interference between the toilet 2 and the cover plate 4 can also be avoided by adjusting the stroke of the drive member 11, the initial angle (the angle between the drive member 11 and the bed frame 5 when the toilet 2 is in the initial position), and the specific parameters of the driven part 3.

[0070] In one exemplary embodiment, such as Figures 1-5 As shown, the driven part 3 includes a first rod 31 and a second rod 32. The first rod 31 extends downward from the lower surface of the cover plate 4. The two ends of the second rod 32 are rotatably connected to the first rod 31 and the support frame 122, respectively, so that under the drive of the support frame 122, the first rod 31 is moved horizontally. Under the constraint of the rotating shaft, the first rod 31 also moves vertically, so that the opening and closing ends rotate around the rotating shaft.

[0071] In this embodiment, the rotational connection point between the second rod 32 and the support frame 122 moves along the aforementioned arc trajectory and applies a primarily horizontal thrust to the first rod 31. After receiving this thrust, the first rod 31, being located below the cover plate 4 (i.e., the rotational connection point between the first rod 31 and the second rod 32 is below the cover plate 4), and the cover plate 4 is constrained by the pivot, generates a torque that causes the cover plate 4 to rotate around the pivot. In other words, when the toilet bowl 2 (support frame 122) moves approximately toward the opening 61, the cover plate 4 is thrust and rotates counterclockwise along the pivot; when the toilet bowl 2 (support frame 122) moves approximately toward the sealing cover 7, the cover plate 4 is tensioned and rotates clockwise along the pivot.

[0072] It should be noted that in the embodiments disclosed herein, the length of the first rod 31 must meet the linkage requirements between the toilet bowl 2 and the lid 4. Specifically, when the toilet bowl 2 is in the first state, the lower end of the first rod 31 (the rotatable connection end with the second rod 32) should be approximately flush with the support frame 122. That is, in this state, the angle between the second rod 32 and the support frame 122 is controlled within a reasonable range, for example, ±10° (the specific value can be determined in conjunction with other parameters). If the first rod 31 is designed to be too short, the lid 4 may be blocked upwards and unable to open when the toilet bowl 2 moves toward the opening 61. If the first rod 31 is designed to be too long, the lid 4 may not be able to open completely, affecting the positioning and use of the toilet bowl 2.

[0073] According to embodiments of this disclosure, such as Figures 1-6 As shown, the driven part 3 also includes a third rod 33, which extends upward from the upper surface of the support frame 122. The first end of the second rod 32 is rotatably connected to the first rod 31, and the second end of the second rod 32 is rotatably connected to the third rod 33, so as to rotate relative to the support frame 122.

[0074] In this implementation, since the third rod 33 is relatively fixed to the support frame 122, the third rod 33 and the support frame 122 can be regarded as a whole. The second end of the second rod 32 is rotatably connected to the third rod 33, that is, the second rod 32 is rotatably connected to the support frame 122 as described in the above embodiment. By extending the third rod 33 from the support frame 122, the smoothness of the driven part 3 in the transmission process is improved, and jamming and jamming phenomena are reduced.

[0075] Further according to embodiments of this disclosure, such as Figures 1-6 As shown, the first member 31 and the third member 33 overlap at least partially in the vertical direction, so that the second end of the second member 32 is higher than the first end in the vertical direction.

[0076] In this implementation, as described in the above embodiments, the angle between the second rod 32 and the support frame 122 needs to be controlled within a reasonable range. In this embodiment, by making the first rod 31 and the third rod 33 overlap in the vertical direction, the second end of the second rod 32 is higher than the first end in the first state of the toilet 2. The third rod 33, the second rod 32 and the first rod 31 form a "Z" shaped structure, so that when the toilet 2 moves toward the opening 61, it provides more downward oblique thrust to the first rod 31 and the cover plate 4, making it easier for the cover plate 4 to open.

[0077] In some other embodiments, the first rod 31 and the second rod 32 are rotatably connected while being slidably connected. That is, the rotatable connection point of the first rod 31 and the second rod 32 can move along the extension direction of the second rod 32 or the extension direction of the first rod 31, so as to provide more redundancy for the driven part 3 and further reduce the probability of jamming.

[0078] It should also be noted that the sliding range of the above-mentioned rotating connection points should not be too large, so as not to affect the normal linkage between the toilet bowl 2 and the toilet seat 4.

[0079] In one exemplary embodiment, such as Figure 2 and Figure 4 The bed board 6 shown includes a horizontal part 62 and a movable part 63. The horizontal part 62 is laid on the bed frame 5. The movable part 63 is rotatably connected to the horizontal part 62 and has a horizontal state parallel to the horizontal part 62, and an inclined state that maintains a preset angle with the horizontal part 62.

[0080] In this embodiment, the opening 61 is located on the horizontal part 62, and when the movable part 63 is in a horizontal state, the patient can lie flat on the bed board 61. When the movable part 63 is in an inclined state, the patient can adjust and lock the angle between the movable part 63 and the horizontal part 62 according to actual needs, so as to sit on the horizontal part 62 and lean against the movable part 63.

[0081] According to embodiments of this disclosure, the movable part 63 adjusts the preset angle between itself and the horizontal part 62 via a lifting mechanism. For example, the fixed end of the electric push rod is mounted on the bed frame 5, and the movable end is rotatably connected to the lower surface of the movable part 63. When the movable end moves away from or closer to the fixed end, the preset angle between the movable part 63 and the horizontal part 62 decreases or increases. As another example, in a lead screw and nut mechanism, the lead screw is mounted on the bed frame 5 via a bearing seat and can rotate around its axis. The nut reciprocates vertically under the drive of the lead screw and is rotatably connected to the movable part 63 to raise or release the movable part 63 and adjust the preset angle.

[0082] In some other embodiments, the movable part 63 includes a middle plate 631 and two side plates 632. The middle plate 631 is hinged to the horizontal part 62 via a hinge shaft. The two side plates 632 are respectively disposed on both sides of the middle plate 631 and are hinged to the middle plate 631 via a hinge shaft. By adjusting the included angle between the side plates 632 and the middle plate 631, the patient can be surrounded and protected, the patient can be assisted in turning over, and the patient can be prevented from falling off the nursing bed.
