Description

Technical Field

[0001] The present invention belongs to the technical field of nursing beds, and particularly relates to a multifunctional nursing bed and its use method. Background Art

[0002] In the field of medical care, the use of nursing beds is extremely common. Its main function is to provide a comfortable resting environment for patients and facilitate the nursing work of nursing staff. For ordinary patients, although it is a bit uncomfortable to move their bodies when changing bed sheets, they can still cooperate to complete it. However, for special patient groups with limited mobility such as stroke patients, paralyzed patients, patients after surgery, and the elderly, the situation is quite different. Such patients often cannot move independently. When changing bed sheets, it is difficult for a single nursing staff to complete the operations of moving the patient and changing the bed sheets. Usually, two or more nursing staff are required to cooperate. This not only increases the workload of the nursing staff, but also easily brings additional pain to the patient due to the coordination problems during multi-person operations. During the moving process, the patient may suffer physical strain due to improper postures, especially for elderly patients and paralyzed patients with relatively fragile bodies, this risk is even higher.

[0003] In terms of nursing efficiency, the existing method of changing bed sheets is time-consuming and laborious. Nursing staff need to spend a lot of time and energy on moving patients, which means that the number of patients that can be nursed within the same time is reduced, affecting the overall efficiency of nursing work. In an environment with tight medical resources such as a hospital, the reduction in nursing efficiency will further exacerbate the tension of resources. Moreover, frequently moving patients may also affect the rehabilitation process of patients. For patients with unstable conditions, it may even lead to the aggravation of the condition. From the psychological perspective of patients, the frequent and uncomfortable moving process will cause psychological pressure and uneasiness for patients. Patients may have a fear of the operation of changing bed sheets, which is not conducive to the mental health and disease recovery of patients. For long-term bedridden patients, this psychological burden may further affect their quality of life and confidence in rehabilitation. Therefore, developing a nursing bed that can facilitate changing bed sheets without moving patients has important practical significance. It can reduce the workload of nursing staff, improve nursing efficiency, and at the same time enhance the medical experience of patients and promote the rehabilitation process of patients.

[0051] The beneficial effects of the present invention:

[0052] 1. When changing the bed sheet of a traditional nursing bed, for patients with limited mobility, multiple nursing staff are often required to cooperate to move the patient, which is cumbersome and laborious. Through the coordinated operation of the bed body, winding component, moving component, pressing component, tensioning component, etc., the present invention realizes the function of changing the bed sheet without moving the patient.

[0055] 4. The tensioning component of the present invention controls the tension degree of the tensioning cloth through a second servo motor, which can not only ensure the integrity of the strip pad during daily use to provide stable support for the patient, but also enable the strip pad to move flexibly during bed sheet replacement for convenient operation.

[0056] 5. The hidden plate design on the headboard of the present invention not only protects the winding component, but also improves the aesthetic appearance of the nursing bed and the comfort of the patient lying.

[0057] 6. The entire device in this solution has the dual functions of bed sheet collection and laying. Through the coordinated operation of the winding component, moving component, pressing component, etc., the used old bed sheet can be quickly and efficiently wound up, and at the same time, the new bed sheet can be accurately and smoothly laid. This design greatly expands the functional use of the device for bed sheets, not only significantly simplifies the operation process of changing bed sheets, but also improves the replacement efficiency and quality, brings great convenience to the nursing work, and effectively guarantees the patient's use experience.

[0076] In order to enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be further described below with reference to the drawings and embodiments.

[0077] As Figure 1 shown, the first aspect of the present application provides a multi-functional nursing bed, including:

[0078] The bed body 1 includes a bed board 11 and two bed edge beams 12 , and a pressing groove 13 is formed on the bed edge beams 12 .

[0079] like Figure 1 As shown, the bed body 1 is the basic structure of the nursing bed, which plays a key role in supporting the entire nursing bed and carrying the patient. It includes a bed board 11, two bedside beams 12, and a footboard and other components, which are the various components of the existing nursing bed. Other components have not been modified or applied in the embodiment, so other components are not described. The bed board 11 provides a flat surface for the patient to lie flat and directly bears the patient's weight. The bedside beam 12 strengthens the structural stability of the bed body, and the pressing groove 13 opened thereon provides a specific position for the subsequent installation of the pressing component 5, so that the pressing component can act accurately on the corresponding position. It is an indispensable part of the entire nursing bed structure.

[0080] A plurality of strip mats 21 are sequentially arranged along the length direction of the bed board 11 on a side of the bed board 11 away from the bed body 1 , and an elastic member 22 is respectively provided between each strip mat 21 and the bed board 11 .

[0081] like Figure 2 As shown, multiple strip pads 21 are arranged in sequence along the length of the bed board 11, on the side of the bed board 11 away from the bed body 1. Together, they form a functional layer similar to a mattress, serving as a carrier for laying sheets and providing comfortable support for the patient. The elastic members 22, located between each strip pad 21 and the bed board 11, are typically made of a highly elastic material. Their primary function is to provide the strip pads 21 with elasticity. When pressure is applied, the elastic members 22 compress, causing the strip pads 21 to sag. When the pressure is removed, the elastic members 22 return to their original shape, driving the strip pads 21 back into place, thus ensuring that the patient always receives stable and comfortable support.

[0082] like Figure 5 As shown, in an optional embodiment, the elastic member 22 is a spring. Its main function is to provide elasticity to the strip pad 21. When pressure is applied, the elastic member 22 compresses, causing the strip pad 21 to sag. When the pressure is relieved, the elastic member 22 returns to its original shape, driving the strip pad 21 to return to its original position, thereby ensuring that the patient always has a stable and comfortable support experience.

[0083] In an optional embodiment, the elastic member 22 is an air spring or a disc spring, which can drive the strip pad 21 to move straight up and down to avoid misalignment and jamming. It can better meet the functional requirements of the nursing bed, solve problems that may arise with ordinary springs, and optimize the elastic support effect of the strip pad 21.

[0084] Winding component 3, moving component 4 and pressing component 5;

[0085] The rewinding assembly 3 is arranged on the moving assembly 4, and the horizontal height of the rewinding assembly 3 is less than the horizontal height of the strip pad 21, and is used for rewinding or laying the bed sheet.

[0086] As Figure 1 shown, the rewinding assembly 3 is mainly responsible for the rewinding and laying of the bed sheet. It is installed on the moving assembly 4 and is lower in height than the strip pad 21. During the bed sheet replacement process, the rewinding assembly 3 can move along the bed body 1 driven by the moving assembly 4. When the bed sheet needs to be replaced, it can roll up the used old bed sheet; when laying a new bed sheet, it can release and unfold the pre-rolled new bed sheet through its own rotation. This function of the rewinding assembly 3 makes the bed sheet replacement operation more convenient and avoids the cumbersome process of manually pulling the bed sheet in the traditional way.

[0087] As Figure 1 shown, in an alternative embodiment, the width dimension of the strip pad 21 is 70 mm - 100 mm. In this width, the individually downwardly recessed strip pad 21 will not cause discomfort to the patient following the depression due to being too wide. And at this width, it can also better accommodate the bed sheet in the rewound state.

[0088] The moving assembly 4 is arranged on the bed body 1 and is used for driving the rewinding assembly to move.

[0089] The moving assembly 4 is a device for pushing the rewinding assembly 3 to move on the bed body 1. It is installed on the bed body 1 and can drive the rewinding assembly 3 to move smoothly in the length direction of the bed through a specific mechanical structure. In actual use, the moving assembly 4 can accurately control the moving position of the rewinding assembly 3. Whether from the head of the bed to the foot of the bed or from the foot of the bed to the head of the bed, it can ensure that the rewinding assembly 3 accurately reaches the designated position, providing support for the position movement of rewinding and laying the bed sheet.

[0090] The pressing assembly 5 is arranged between the moving assembly 4 and the strip pad 21 and is used for pressing the strip pad 21 when the rewinding assembly 3 moves, providing a moving space for the rewinding assembly 3, including:

[0091] A plurality of first support plates 51, located inside the two pressing grooves 13 and respectively connected to each strip pad 21;

[0092] A plurality of first arc-shaped plates 52 are respectively arranged on each first support plate 51;

[0093] Two second support plates 53 are respectively located inside the two pressing grooves 13 and are connected to the moving assembly 4;

[0094] Two second arc-shaped plates 54 are respectively arranged on the two second support plates 53, and the second arc-shaped plate 54 and the first arc-shaped plate 52 are located on the same horizontal plane so that the second arc-shaped plate 54 can squeeze the first arc-shaped plate 52.

[0095] AsFigure 3 , 4 As shown in FIGS. 5, the pressing assembly 5 is located between the moving assembly 4 and the strip pad 21. Its core function is to press the strip pad 21 when the winding assembly 3 moves. It includes a plurality of first support plates 51, a plurality of first arc plates 52, two second support plates 53 and two second arc plates 54. Among them, the plurality of first support plates 51 are located in the pressing groove 13 and are connected to each strip pad 21, responsible for transmitting the pressing force to the strip pad 21. The first arc plate 52 is installed on the first support plate 51 and works in cooperation with the second arc plate 54. The two second support plates 53 are also in the pressing groove 13 and are connected to the moving assembly 4, and the second arc plate 54 is arranged on the second support plate 53. When the moving assembly 4 drives the pressing assembly 5 to move, the second arc plate 54 squeezes the first arc plate 52, and then the corresponding first support plate 51 moves downward through the first support plate 51, driving the corresponding first support plate 51 and the strip pad 21 to sink, providing a moving space for the winding assembly 3, and ensuring that the winding assembly 3 can move smoothly without affecting the patient.

[0096] Through the coordinated work of the bed body 1, the strip pad 21 and the elastic member 22, the winding assembly 3, the moving assembly 4 and the pressing assembly 5, the function of replacing the bed sheet without moving the patient is realized. When replacing the bed sheet, the moving assembly 4 drives the winding assembly 3 and the pressing assembly 5 to move. The pressing assembly 5 first presses the strip pad 21 in front of the winding assembly 3 to sink, opening up a moving channel for the winding assembly 3. The winding assembly 3 winds up the old bed sheet or lays a new bed sheet during the moving process. This design not only greatly reduces the work burden of the nursing staff, avoids the possible injuries caused by moving the patient, but also improves the efficiency of replacing the bed sheet, and at the same time ensures the comfort of the patient during the replacement process, improving the quality of nursing services.

[0097] Furthermore, the winding assembly 3 includes:

[0098] Two support plates 31, respectively located on the left and right sides of the bed body 1 and connected to the moving assembly 4;

[0099] A winding rod 32, rotatably assembled between the two support plates 31, and the horizontal height of the winding rod 32 is less than the horizontal height of the strip pad 21;

[0100] A first servo motor 33, fixedly assembled on the support plate 31, and the output end of the first servo motor 33 is connected to the winding rod 32.

[0101] Two support plates 31 are respectively located on the left and right sides of the bed body 1, playing a key supporting and connecting role. They are connected to the moving component 4, enabling the winding component 3 to move on the bed body by means of the power of the moving component 4, providing the ability to adjust the position for winding and laying the bedsheet. At the same time, the support plate 31 provides a stable installation foundation for the winding rod 32, ensuring the stability of the winding rod 32 during rotation, preventing it from shaking or shifting, and ensuring that the operations of winding and laying the bedsheet can be carried out accurately.

[0102] As Figure 2 and 3 shown, the winding rod 32 is rotationally assembled between the two support plates 31. It is the core component for winding and laying the bedsheet and can wind or release the bedsheet through its own rotation during operation. Its horizontal height is less than the horizontal height of the strip pad 21. During the operation of the nursing bed, the winding rod 32 can move below the upper surface of the strip pad 21 when it is not pressed, that is, only the strip pad 21 at the position of the winding rod 32 will be pressed. Compared with the overall mattress composed of each strip pad 21, the winding rod 32 is recessed into the mattress, effectively avoiding unnecessary interference to the patient when changing the bedsheet. When it is necessary to wind the used bedsheet, the winding rod 32 winds the bedsheet around its own surface by rotating; while when laying a new bedsheet, it rotates in the reverse direction to gradually release and unfold the pre-rolled new bedsheet. The smooth rotation of the winding rod 32 is the key link to achieve efficient bedsheet replacement.

[0103] As Figure 2 shown, the first servo motor 33 is fixedly assembled on the support plate 31, providing power for the rotation of the winding rod 32. The servo motor has the characteristics of high control precision and fast response speed, and can accurately control the rotation speed and angle of the winding rod 32. When winding the bedsheet, the rotation speed of the motor can be accurately controlled according to the length and material of the bedsheet to make the winding process smooth and efficient; when laying the bedsheet, it can release the bedsheet at a uniform speed to ensure that the bedsheet is laid flat and neatly. At the same time, the stable operation of the first servo motor 33 also ensures the reliability of the overall operation of the winding component 3, reducing the problem of unsmooth winding or laying of the bedsheet caused by unstable power.

[0104] Furthermore, a clamping cavity 34 is arranged inside the winding rod 32, and a placement notch 35 communicating with the clamping cavity 34 is opened on the winding rod 32 to enable the clamping cavity 34 to communicate with the outside;

[0105] The winding component 3 further includes:

[0106] A rotating rod 35, arranged inside the clamping cavity 34, and the rotating rod 35 is rotationally connected to the winding rod 32. One end of the rotating rod 35 away from the first servo motor 33 rotates through the winding rod 32 and the support plate 31;

[0107] A first clamping block 36, arranged on the rotating rod 35;

[0108] The second clamping block 37 is located inside the clamping cavity 34 and is fixedly connected to the winding rod 32;

[0109] The handle 38 is arranged at one end of the rotating rod 35 passing through the support plate 31.

[0110] Such as Figure 5 and 6 As shown, the clamping cavity 34 inside the winding rod 32 and the placement notch 35 communicating therewith are the basis of the entire clamping structure. The placement notch 35 connects the clamping cavity 34 with the outside world, facilitating the insertion of one end of the sheet into the clamping cavity 34. This design provides the space and path for the subsequent clamping operation of the sheet and is the key starting point for fixing the sheet on the winding rod 32.

[0111] The rotating rod 36 is arranged inside the clamping cavity 34 and is rotatably connected to the winding rod 32. One end of the rotating rod 36 rotatably passes through the winding rod 32 and the support plate 31. The rotating rod 36 plays an important role in transmitting force and adjusting the clamping state. By rotating the rotating rod 36, the first clamping block 37 arranged thereon can be driven to move, thereby adjusting the relative position and clamping force between the first clamping block 37 and the second clamping block 38. Moreover, the rotating rod 36 passes through the support plate 31, enabling external operations such as rotating the handle 39 to directly act on the rotating rod 36, realizing convenient control of the clamping structure.

[0112] The first clamping block 37 is arranged on the rotating rod 36, and the second clamping block 38 is fixed inside the clamping cavity 34 of the winding rod 32. When it is necessary to clamp the sheet, rotate the rotating rod 36, and the first clamping block 37 will move along with the rotating rod 36, approaching or moving away from the second clamping block 38. In this way, the two clamping blocks can tightly clamp one end of the sheet placed in the clamping cavity 34. The two clamping blocks cooperate with each other to ensure that the sheet will not loosen or slip during the winding and laying processes, ensuring the smooth progress of the sheet replacement operation.

[0113] Such as Figure 6 As shown, further, the holding cavity 34 is cylindrical, and a clamping cavity and a relaxation cavity are respectively formed inside the clamping cavity 34 from both sides of the second clamping block 37 to the placement notch 35, and the inner diameter of the relaxation cavity is larger than that of the clamping cavity. The first clamping block 36 is a fan-shaped setting matching the clamping cavity, so as to form a clamping gap between the first clamping block 36 and the region with a smaller inner diameter of the clamping cavity 34.

[0114] The clamping cavity 34 is cylindrical, providing a neat spatial arrangement for the internal components. This facilitates the installation and movement of components such as the rotating rod 36, the first clamping block 37, and the second clamping block 38, ensuring their smooth operation within the reeling rod 32. Furthermore, the cylindrical structure evenly distributes the clamping force, ensuring a more balanced force on the sheet when clamped, and preventing damage to the sheet due to excessive localized force.

[0115] Inside the clamping cavity 34, a clamping cavity and a relaxing cavity are formed from both sides of the second clamping block 38 to the placement slot 35, and the inner diameter of the relaxing cavity is larger than the inner diameter of the clamping cavity. The larger inner diameter of the relaxing cavity provides enough space for placing one end of the bed sheet, which is convenient for operation. The nursing staff can easily put the bed sheet into the relaxing cavity from the placement slot 35, and then adjust it to the clamping cavity position for clamping. The relatively small inner diameter of the clamping cavity, combined with the design of the first clamping block 37, can achieve tight clamping of the bed sheet. During the process of rolling or laying the bed sheet, the clamping cavity with a smaller inner diameter can prevent the bed sheet from sliding at the clamping point, ensuring that the bed sheet is stably fixed on the winding rod 32.

[0116] like Figure 6 As shown, the first clamping block 37 is designed to be fan-shaped to match the clamping cavity, and this shape can better adapt to the structure of the clamping cavity. When the first clamping block 37 moves under the drive of the rotating rod 36, a clamping gap is formed between its fan-shaped structure and the area with a smaller inner diameter of the clamping cavity. When the sheet is not clamped, the first clamping block 37 is located inside the relaxation cavity, and when the sheet is placed into the clamping cavity 34 from the placement slot 35, it is located between the first clamping block 37 and the second clamping block 38. When clamping, the position of the first clamping block 37 is adjusted by rotating the rotating rod 36, so that the first clamping block 37 and the second clamping block 38 move closer to each other, so that the first clamping block 37 and the second clamping block 38 fit each other and clamp the sheet therebetween. At the same time, since the inner diameter of the clamping cavity is small, the size of the clamping gap is set by setting the size of the first clamping block 37, so that the sheet can be further restricted in friction with the sheet in this clamping gap, so as to prevent too little placement of some areas when the sheet is placed into the clamping cavity 34 and not being clamped, resulting in wrinkles in subsequent rolling or laying.

[0117] Furthermore, magnets are disposed inside the first clamping block 36 and the second clamping block 37 .

[0118] During the process of rolling up or laying the bed sheet, the bed sheet may become loose due to various external forces, affecting the smooth progress of the replacement operation. The magnets inside the first clamping block 37 and the second clamping block 38 will attract each other, generating an additional clamping force. Similarly, during daily use, even when the nursing bed moves or the patient turns over, this magnetic attraction can ensure that the two clamping blocks firmly clamp the bed sheet, preventing the bed sheet from slipping. For example, when the nursing bed vibrates during movement, the ordinary clamping method may cause the bed sheet to gradually become loose, but the presence of the magnet can effectively avoid this situation and ensure that the work of rolling up and laying the bed sheet is not disturbed.

[0119] Further, the moving assembly 4 includes:

[0120] Two lead screws 41, which are respectively rotatably arranged on the left and right sides of the bed body 1;

[0121] Two stepper motors 42, which are fixedly assembled on the bed body 1, and the output ends of the two stepper motors 42 are respectively connected to the two lead screws 41;

[0122] Two moving blocks 43, which are respectively sleeved on the two lead screws 41 in a threaded manner, and the moving blocks 43 are respectively connected to the winding assembly 3 and the pressing assembly 5.

[0123] The lead screws 41 are respectively rotatably arranged on the left and right sides of the bed body 1. Specifically, they can be rotatably connected to the headboard 14 and the footboard, which is the key component for the moving assembly 4 to achieve linear motion. The lead screw has a unique thread structure. When the lead screw rotates, the cooperating moving block 43 will move along the axial direction of the lead screw. The two lead screws work synchronously, which can ensure that the winding assembly 3 and the pressing assembly 5 connected thereto remain balanced during movement, avoiding tilting or offsetting, and ensuring that the operations of rolling up and laying the bed sheet can be carried out accurately. Moreover, the high-precision machining of the lead screw can achieve precise displacement control, meeting the precise requirements for the positions of the components in different operation scenarios of the nursing bed.

[0124] As Figure 2 shown, the stepper motor 42 is fixedly assembled on the bed body 1. Similarly, it can be specifically connected to the headboard 14 or the footboard. Its output end is respectively connected to the two lead screws 41, providing power for the rotation of the lead screws. The stepper motor has precise control characteristics and can precisely control the rotation angle and number of steps. During the process of replacing the bed sheet of the nursing bed, by controlling the rotation of the stepper motor 42, the rotation angle of the lead screw 41 can be precisely adjusted, and then the moving distance and speed of the winding assembly 3 and the pressing assembly 5 can be precisely controlled. For example, when rolling up the bed sheet, according to the length and rolling speed requirements of the bed sheet, the operation of the stepper motor 42 can be precisely controlled to make the winding assembly 3 move uniformly and complete the rolling-up action; when laying the bed sheet, the components can also be made to lay the new bed sheet in place smoothly by controlling the stepper motor 42, improving the accuracy and stability of the operation.

[0125] As shown Figure 2 , 3 and as shown in Fig. 7, the moving blocks 43 are respectively sleeved on two lead screws 41 by threads. They are important components connecting the winding assembly 3, the pressing assembly 5 and the lead screw 41. Specifically, in this embodiment, the moving blocks 43 are respectively connected to the support plate 31 and the second support plate 53. When the lead screw 41 rotates driven by the stepper motor 42, the moving blocks 43 will move linearly along the axial direction of the lead screw according to the rotation direction and the number of turns of the lead screw. Since the moving blocks 43 are respectively connected to the winding assembly 3 and the pressing assembly 5, their movement can drive the winding assembly 3 and the pressing assembly 5 to move synchronously on the bed body 1. The connection manner between the moving blocks 43 and the winding assembly 3 and the pressing assembly 5 is firm and reliable, ensuring that there will be no loosening or disconnection during the movement, and guaranteeing the normal operation of the function of replacing the bed sheet of the nursing bed.

[0126] Furthermore, it further includes a tensioning assembly 6, and the tensioning assembly 6 includes:

[0127] A rotating shaft 61, rotatably arranged on the bed body 1, and the length direction of the rotating shaft 61 is the same as the length direction of the strip cushion 21;

[0128] A tensioning cloth 62, sequentially sliding through each strip cushion 21 along the length direction of the bed body 1, and one end of the tensioning cloth 62 is fixedly connected to the strip cushion 21 that is farthest from the rotating shaft 61, and the other end of the tensioning cloth 62 is fixedly connected to the rotating shaft 61;

[0129] A second servo motor 63, fixedly arranged on the bed body 1, and the output end of the second servo motor 63 is connected to the rotating shaft 61.

[0130] The rotating shaft 61 is rotatably arranged on the bed body 1, and its length direction is the same as the length direction of the strip cushion 21. It provides a fixed and rotating support point for the tensioning cloth 62. When the second servo motor 63 drives the rotating shaft 61 to rotate, the tensioning cloth 62 will be wound and released along with the rotation of the rotating shaft 61. The stability and smooth rotation of the rotating shaft 61 are the basis for ensuring the normal operation of the tensioning cloth 62. Its installation position and structural design ensure that during the use of the entire nursing bed, the tensioning cloth 62 can uniformly apply force to each strip cushion 21, maintaining the integrity of the strip cushion 21 or enabling it to move flexibly as needed.

[0131] The tension cloth 62 is sequentially and slidably passed through each strip cushion 21 along the length direction of the bed body 1. When the tension cloth 62 is in a tensioned state, that is, when the second servo motor 63 drives the rotating shaft 61 to wind up the tension cloth 62, the tension cloth 62 will generate a pulling force on each strip cushion 21, causing the strip cushions 21 to be closely connected to form a whole. In this way, during daily use, when a person presses a certain strip cushion 21 alone, due to the pulling effect of the tension cloth 62, other strip cushions 21 will also be affected, avoiding the situation where a certain strip cushion 21 sinks alone, and providing a stable and flat support surface for the patient. When it is necessary to change the bedsheet, the second servo motor 63 controls the rotating shaft 61 to relax the tension cloth 62. At this time, the connection between the strip cushions 21 becomes loose, and each strip cushion 21 can be pressed alone to cooperate with the winding assembly 3 and the pressing assembly 5 to complete the operation of changing the bedsheet.

[0132] As Figure 8 and 9 shown, the second servo motor 63 is fixedly arranged on the bed body 1, and its output end is connected to the rotating shaft 61. It is the power source and control core of the tensioning assembly 6. The second servo motor 63 has the characteristics of high control accuracy and self-locking function. During the use of the daily care bed, the second servo motor 63 uses the self-locking function to keep the rotating shaft 61 fixed, ensuring that the tension cloth 62 is always in a tensioned state and maintaining the integrity of the strip cushions 21. When it is necessary to change the bedsheet, by controlling the second servo motor 63, it drives the rotating shaft 61 to rotate in the reverse direction to relax the tension cloth 62, so that the strip cushions 21 can move flexibly. Moreover, the second servo motor 63 can accurately control the rotation angle and speed of the rotating shaft 61, thereby precisely adjusting the tension degree of the tension cloth 62 to meet different usage requirements.

[0133] In an alternative embodiment, the multifunctional care bed can also be provided with a processor and a corresponding controller, such as a programmable logic controller PLC, which is electrically connected to the first servo motor 33, the stepping motor 42, and the second servo motor 63, so as to comprehensively control the first servo motor 33, the stepping motor 42, and the second servo motor 63. Thus, more intelligent operation requirements can be achieved. At the same time, a position sensor, such as a limit switch, can also be arranged at the corresponding position of the bed body 1, so as to more accurately control the movement of the moving block 43. This is the prior art and is widely used in the movement control of precision components, and will not be described in detail here.

[0134] Furthermore, the bed body 1 further includes a headboard 14, and a hidden board 15 with the same horizontal height as the strip cushion 21 is provided on the headboard 14.

[0135] The headboard 14, as a part of the bed body 1, provides support for the patient to lean on, increasing the comfort of the patient when using the nursing bed. When the patient sits up, the headboard can prevent the patient's back from directly touching the cold wall and avoid the patient hitting the wall due to body shaking, playing a certain protective role. At the same time, it also enhances the overall structural stability of the bed body, making the nursing bed more durable.

[0136] As Figure 4 shown, the hidden board 15 is arranged on the headboard 14 and has the same horizontal height as the strip cushion 21. This design plays a key role in the process of changing the bedsheet. After the winding component 3 completes the laying of the new bedsheet, the winding component 3 can be hidden under the hidden board 15. In this way, the winding component 3 is not exposed, avoiding damage to it due to collision and preventing the patient from accidentally touching the winding component and getting injured. At the same time, the existence of the hidden board 15 makes the appearance of the nursing bed more tidy and beautiful, improving the overall visual effect and making the nursing bed more coordinated in the ward environment.

[0137] The hidden board 15 has the same horizontal height as the strip cushion 21, ensuring the flatness of the surface of the patient's lying area. When the patient lies down, they will not feel uncomfortable due to the height difference at the head part of the bed. Moreover, after the winding component 3 is hidden under the hidden board 15, from the patient's perspective, the overall surface of the bed still remains flat without a protruding feeling, further improving the patient's use experience.

[0138] Furthermore, the strip cushion 21 includes: a connecting plate 211 and a soft cushion 212;

[0139] The connecting plate 211 is connected to the elastic member 22;

[0140] The soft cushion 212 is arranged on the side of the connecting plate 211 away from the elastic member 22.

[0141] The connecting plate 211 plays a role in connecting and transmitting force. It is connected to the elastic member 22 and can stably transmit the supporting force of the elastic member 22 to the entire strip cushion 21. When the elastic member 22 is compressed or rebounds due to force, the connecting plate 211 can ensure that this force is evenly distributed, avoiding uneven local force on the strip cushion 21. Moreover, the connecting plate 211 provides an installation base for the soft cushion 212, ensuring the fixed position of the soft cushion 212 so that it will not easily shift during use, ensuring that the patient can always obtain stable support.

[0142] As Figure 5 and 10As shown, the cushion 212 is arranged on the side of the connecting plate 211 away from the elastic member 22, and contacts the patient through the bed sheet, which is the key to improving patient comfort. The cushion 212 is generally made of soft, skin-friendly materials, such as sponge, latex, etc., which can effectively relieve the pressure between the patient's body and the bed surface, and reduce the patient's fatigue from lying for a long time. For patients with limited mobility, the cushion 212 can also reduce the risk of pressure sores caused by prolonged pressure on local parts of the body. In addition, the soft nature of the cushion 212 can also absorb the vibrations generated when the patient turns over or moves to a certain extent, creating a quieter and more comfortable resting environment for the patient.

[0143] A second aspect of the present application provides a method for using a multi-purpose nursing bed, which is applicable to any multi-purpose nursing bed in the first aspect, and the method comprises:

[0144] S1. Daily use

[0145] The patient lies on the nursing bed, the soft pad 212 of the strip pad 21 provides comfortable support, and the elastic member 22 ensures stable support; the second servo motor 63 of the tightening component 6 is started to drive the rotating shaft 61 to roll up the tightening cloth 62, so that the strip pad 21 forms a whole and avoids the sinking of a single strip.

[0146] At this time, the reeling rod 32 is located below the hidden plate 15 and is in a hidden state.

[0147] S2. Change bed sheets

[0148] S21: Place the multi-purpose nursing bed in a stable position and check whether the connections of the bed body 1, winding assembly 3, moving assembly 4, pressing assembly 5, tightening assembly 6 and other components are stable to ensure that there is no damage or looseness;

[0149] If the power supply involves electric components, ensure the normal operation of the equipment;

[0150] S22, start preparation, operate the controller of the nursing bed such as PLC, control the second servo motor 63 to reverse, loosen the tight cloth 62, so that the strip pad 21 can be pressed separately.

[0151] S23, roll up the old bed sheet, start the controller, control the stepper motor 42 to rotate forward, drive the screw 41 to rotate, and make the moving block 43 move along the axial direction of the screw, driving the winding assembly 3 and the pressing assembly 5 to move from the head of the bed to the foot of the bed; during the movement, the second curved plate 54 of the pressing assembly 5 squeezes the first curved plate 52, so that the first support plate 51 drives the strip pad 21 to sink, providing moving space for the winding rod 32; at the same time, the first servo motor 33 drives the winding rod 32 to rotate, and rolls up the old bed sheet.

[0152] S24. Replace the old bedsheet with a new one. After the winding component 3 moves to the end of the bed, stop the stepper motor 42 and the first servo motor 33. Remove the old bedsheet and prepare a clean one. Turn the handle 38 to drive the rotating rod 35 to move the first clamping block 36 to the slack cavity, increasing the distance between the first clamping block 36 and the second clamping block 37. Place one end of the bedsheet into the clamping cavity 34 through the placement slot 35 and position it between the first clamping block 36 and the second clamping block 37. Reverse the rotation of the handle 38 to make the first clamping block 36 approach the second clamping block 37 and clamp the bedsheet. Utilize the magnets inside the first clamping block 36 and the second clamping block 37 to enhance the clamping stability.

[0153] S25. Lay the new bedsheet. Operate the controller again to control the stepper motor 42 to reverse, driving the winding component 3 and the pressing component 5 to move from the end of the bed to the head of the bed. At the same time, the first servo motor 33 drives the winding rod 32 to rotate in the reverse direction to release the new bedsheet. After the winding component 3 moves to the head of the bed, make it hide under the hidden plate 15.

[0154] S26. Restore the usage state. Control the second servo motor 63 to rotate forward through the controller to wind up the tension cloth 62, making the strip pads 21 form a whole again. Turn off the controller to complete the operation of changing the bedsheet.

[0155] In this way, in an environment with tight medical resources such as hospitals, nursing efficiency is crucial. The operation of changing the bedsheet of the nursing bed of the present invention is convenient and efficient, avoiding the process of spending a lot of time moving patients in the traditional method. Nursing staff can care for more patients within the same time, improving the overall nursing work efficiency and alleviating the situation of tight medical resources.

[0156] For patients with limited mobility such as those with stroke, paralysis, after surgery, and the elderly, the traditional way of changing bedsheets will not only cause physical discomfort to them, but may also cause physical strains due to improper postures, affecting the rehabilitation process. The present invention does not require moving the patient when changing the bedsheet, reducing the pain of the patient and avoiding the risk of physical injury caused by changing the bedsheet. At the same time, it also reduces the patient's fear of changing the bedsheet, which is beneficial to the patient's mental health and condition recovery, and improves the patient's medical experience and quality of life.

[0157] The above embodiments are only used to exemplarily illustrate the principles and effects of the present invention, rather than to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
