Nursing bed and control method thereof

Abstract

This application relates to a nursing bed and its control method. The nursing bed includes a fixed bed frame, a movable bed frame, and a linkage structure. The movable bed frame can move in and out of the accommodating space and can be connected to or separated from the fixed bed frame independently. The movable bed frame has a lying position and a working position. The movable bed frame can be connected to the fixed bed frame in a lying position and in a working position. When the movable bed frame and the fixed bed frame are connected, and the movable bed frame switches from the lying position to the working position, the movable bed frame can drive the fixed bed frame to move through the linkage structure so that the fixed bed frame maintains the same posture as the movable bed frame. This eliminates the need to pre-reset the movable bed frame from the working position to the lying position before connecting it, simplifying the operation steps, saving time and effort, and realizing the overall synchronous back and leg lifting movements of the nursing bed. This eliminates the limitations of the bed frame's usage area and meets more usage needs.

Description

Technical Field

[0001] This application relates to the field of nursing tool technology, and in particular to a nursing bed and a method for controlling the same. Background Technology

[0002] A nursing bed combines a movable bed frame with a fixed bed frame. Typically, space is reserved next to the fixed bed frame to accommodate the movable frame, allowing the two frames to be joined to form a larger bed. The movable frame can also be switched to a working position, serving as a means of transportation for the patient. Nursing beds usually also need to have functions such as leg raising, leg lowering, back support, and turning over to meet the different needs of patients.

[0003] In existing nursing beds, movable beds can usually switch between a supine position and a working position to enable actions such as back lifting and leg lifting. However, after the movable bed is separated from the fixed bed, it can only be connected to the fixed bed in a supine position. If the movable bed is moved to the side of the fixed bed in a working position, it is necessary to switch the movable bed in the working position to a supine position before connecting it to the fixed bed, which is time-consuming and laborious.

[0004] In addition, after the movable and fixed bed frames are joined together, usually only the movable bed frame can perform actions such as lifting the back and legs. When the patient is lying on the nursing bed and has the need to lift their back or legs, the area where the nursing bed can be used is very limited. Summary of the Invention

[0005] Therefore, it is necessary to provide a nursing bed that can be connected to a fixed bed when the movable bed is in a lying or working position, making operation simpler and more convenient. Furthermore, after the movable and fixed beds are connected, both the movable and fixed beds can be used for back lifting, leg lifting, and other movements.

[0006] This application provides a nursing bed, including a fixed bed frame, a movable bed frame, and a linkage structure. The fixed bed frame has a accommodating space on its side, and the movable bed frame can enter and exit the accommodating space, and can be connected to or separated from the fixed bed frame independently. The movable bed frame has a lying position and a working position. The movable bed frame can be connected to the fixed bed frame in the lying position, and the movable bed frame can be connected to the fixed bed frame in the working position. When the movable bed frame and the fixed bed frame are connected, and the movable bed frame switches from the lying position to the working position, the movable bed frame can drive the fixed bed frame to move through the linkage structure, so that the fixed bed frame maintains the same posture as the movable bed frame.

[0007] In one embodiment, the linkage structure has a separated state and a connected state. When the movable bed and the fixed bed are in a spliced ​​state, and the movable bed is in a lying position and the linkage structure is in a connected state, the movable bed can drive the fixed bed to move through the linkage structure. When the linkage structure is in a separated state, the linkage between the movable bed and the fixed bed is released. And / or, the linkage structure is provided on one or both of the movable bed and the fixed bed.

[0008] In one embodiment, the linkage structure includes an abutment and an elastic member disposed on the fixed bed body. The abutment is slidably disposed on the fixed bed body and can slide relative to the fixed bed body to a first position corresponding to the separated state and a second position corresponding to the connected state. The elastic member acts on the abutment and causes the abutment to have a tendency to slide towards the second position. The upper end of the abutment has a guide surface. The movable bed body and the fixed bed body are spliced ​​together, and during the process of the movable bed body switching from the working state to the lying posture, the movable bed body abuts against the guide surface and pushes the abutment to slide from the second position to the first position. When the movable bed body and the fixed bed body are connected through the linkage structure, a portion of the movable bed body is located below the abutment.

[0009] In one embodiment, the movable bed is provided with a control module, which is used to control the movable bed to switch between a lying position and a working position. The control module has a first interface, and the fixed bed is provided with a second interface. The second interface is electrically connected to an external power source. When the movable bed and the fixed bed are spliced ​​together, the first interface and the second interface are electrically connected, and the external power source supplies power to charge the control module.

[0010] In one embodiment, the fixed bed and / or the movable bed are equipped with a limiting structure; the limiting structure has a first state that locks the fixed bed and the movable bed together and a second state that releases the locking between the fixed bed and the movable bed; when the limiting structure is in the second state, the movable bed can be separated from the fixed bed and operate independently; the control module is electrically connected to the limiting structure and is used to control the limiting structure to switch between the first state and the second state.

[0011] In one embodiment, the fixed bed is provided with a turning mechanism for driving the fixed bed and the movable bed to turn over. After the first interface and the second interface are electrically connected, the control module is used to control the turning mechanism to drive the fixed bed and the movable bed to perform the turning action.

[0012] In one embodiment, the fixed bed body is equipped with guide rollers, and / or the movable bed body is equipped with guide rollers; the guide rollers guide the fixed bed body and the movable bed body when they are brought close together and when they are separated from each other.

[0013] This application also provides a control method for a nursing bed, used to control the posture switching of the nursing bed as described above, the control method comprising the following steps:

[0014] S100: Obtaining user needs;

[0015] S101: Obtain the splicing status information of the fixed bed frame and the movable bed frame;

[0016] S102: Determine whether the splicing status of the fixed bed frame and the movable bed frame meets the user's needs;

[0017] If satisfied, proceed to step S103;

[0018] Otherwise, adjust the splicing posture of the fixed bed and the movable bed to meet the user's needs before proceeding to step S103;

[0019] S103: Obtain the attitude information of the fixed bed and the movable bed;

[0020] S104: Determine whether the postures of the fixed bed and the movable bed meet the user's needs;

[0021] If satisfied, proceed to step S106;

[0022] Otherwise, proceed to step S105:

[0023] S105: The control module controls the switching postures of the movable bed and the fixed bed to meet user needs;

[0024] S106: Repeat step S100.

[0025] In one embodiment, the movable bed is equipped with a control module for controlling the movable bed to switch between a lying position and a working position; the fixed bed is equipped with a turning mechanism for driving the fixed bed and the movable bed to turn over; the control module has a first interface, the fixed bed has a second interface, and when the movable bed and the fixed bed are spliced ​​together, the first interface and the second interface are electrically connected; the control module is used to control the turning mechanism to drive the fixed bed and the movable bed to perform turning actions.

[0026] Before the control module controls the movable bed to switch postures, it determines whether the movable bed and the fixed bed are in a lying position.

[0027] If so, the control module controls the movable bed to perform leg raising, leg lowering, back raising, or back lowering actions; otherwise, the control module controls the turning mechanism to switch both the movable and fixed bed to a supine position before controlling the movable bed to perform leg raising, leg lowering, back raising, or back lowering actions.

[0028] Before the control module controls the turning mechanism to drive the movable bed and the fixed bed to perform the turning action, it determines whether the movable bed is in a flat position.

[0029] If so, the control module controls the turning mechanism to drive the movable bed and the fixed bed to perform the turning action; otherwise, the control module controls the movable bed to switch to a supine position, and then controls the turning mechanism to drive the movable bed and the fixed bed to perform the turning action.

[0030] In one embodiment, when the nursing bed includes a limiting structure and the control module is electrically connected to the limiting structure for controlling the limiting structure to switch between a first state and a second state;

[0031] Before separating the movable bed from the fixed bed, determine whether both the fixed bed and the movable bed are in a supine position.

[0032] If so, the control module controls the limit structure to switch to the second state;

[0033] Otherwise, the control module controls the movable bed and the fixed bed to switch to the lying position, and then controls the limit structure to switch to the second state.

[0034] Compared with existing technologies, the nursing bed provided in this application has at least the following advantages: The movable bed frame can be connected to the fixed bed frame in a supine position, and also in a working position (such as a working position). This eliminates the need to pre-position the movable bed frame in the working position back to the supine position before connection, simplifying the operation and saving time and effort. Furthermore, after the movable bed frame and fixed bed frame are connected, during the transition from a supine to a working position, the movable bed frame is synchronized with the fixed bed frame via a linkage structure. This allows the fixed bed frame to maintain the same posture as the movable bed frame, enabling synchronized back and leg lifts and other movements of the entire nursing bed. This eliminates the limitations of the bed's usability area and meets a wider range of usage needs. Attached Figure Description

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0064] In traditional nursing beds, when the movable bed 200 and the fixed bed 100 are joined, the movable bed 200 can only be joined to the fixed bed 100 in a supine position. After the movable bed 200 is moved to the side of the fixed bed 100 in a working position (such as a working posture), it must first be switched to a supine position before being joined to the fixed bed 100, which is time-consuming and laborious. Furthermore, the fact that the movable bed 200 needs to be switched to a supine position before being moved to the side of the fixed bed 100 means the patient is transported in a supine position, which can cause the patient feelings of shame and negatively impact their mental health.

[0065] In addition, after the movable bed 200 and the fixed bed 100 are joined together, the patient can only perform actions such as lifting their back and legs in the area of ​​the movable bed 200, which greatly limits the usability of the entire nursing bed.

[0066] For this, please see Figures 1 to 12 This application provides a nursing bed to solve the above-mentioned technical problems.

[0067] Specifically, please combine Figure 1 and Figure 2 This application provides a nursing bed, which includes a fixed bed body 100, a movable bed body 200, and a linkage structure 500. The fixed bed body 100 has a accommodating space 101 on its side. The movable bed body 200 can enter and exit the accommodating space 101 and can be connected to or separated from the fixed bed body 100. The movable bed body 200 has a lying position and a working position. The movable bed body 200 can be connected to the fixed bed body 100 in a lying position, and it can also be connected to the fixed bed body 100 in a working position. When the movable bed body 200 and the fixed bed body 100 are connected, and during the process of switching the movable bed body 200 from the lying position to the working position, the movable bed body 200 can drive the fixed bed body 100 to move through the linkage structure 500, so that the fixed bed body 100 maintains the same posture as the movable bed body.

[0068] The working posture of the movable bed 200 refers to the posture in which the movable bed 200 is in a raised back, raised legs, or lowered legs position, or in a wheelchair position.

[0069] In this way, the movable bed 200 in the nursing bed can be connected to the fixed bed 100 in a supine position or in a working position. There is no need to reset the movable bed 200 in the working position to the supine position before connecting it, which simplifies the operation steps, saves time and effort, and can also take care of the patient's mental health.

[0070] After the movable bed 200 and the fixed bed 100 are joined together, during the process of the movable bed 200 switching from a lying position to a working position, the fixed bed 100 can be moved synchronously through the linkage structure 500, so that the fixed bed 100 maintains the same posture as the movable bed 200. For example, when the movable bed 200 and the fixed bed 100 are joined together, when the movable bed 200 switches from a lying position to a backrest-raised position, the movable bed 200 drives the fixed bed 100 to raise its back synchronously through the linkage structure 500; when the movable bed 200 switches from a lying position to a leg-raised position, the movable bed 200 drives the fixed bed 100 to raise its legs synchronously through the linkage structure 500.

[0071] For example, please see Figure 1 and Figure 2 The nursing bed extends horizontally along its length, and the fixed bed body 100 and the movable bed body 200, when joined together, are distributed along the width of the nursing bed. In this embodiment, a receiving space 101 is formed on the side of the fixed bed body 100, that is, on its right side. This receiving space 101 is adapted to the outer contour of the movable bed body 200, allowing the movable bed body 200 to enter the receiving space 101 from the outside along the width of the fixed bed body 100 and join with the fixed bed body 100 to form a complete bed surface. It is understood that when the movable bed body 200 is removed from the receiving space 101 of the fixed bed body 100, the movable bed body 200 and the fixed bed body 100 separate into two independent main bodies.

[0072] Furthermore, the movable bed 200 can switch between a working posture and a lying posture. Specifically, the movable bed 200 includes a first bed frame 202, which is composed of multiple relatively movable skeletal segments. Specifically, the first bed frame 202 is typically composed of multiple relatively movable skeletal segments, including a back segment, hip segment, thigh segment, and calf segment (the thigh and calf segments can also be collectively referred to as leg segments). The skeletal segments are rotatably connected by hinges or pivots. The movement drive method for each skeletal segment in the first bed frame 202 can adopt a conventional drive form, which will not be elaborated further in this application. A mattress 600 can be installed on the first bed frame 202 to improve user comfort.

[0073] The fixed bed frame 100 also includes a second bed frame 104, which can also accommodate a mattress 600 to improve comfort. The second bed frame 104 is also composed of multiple relatively movable frame segments, including a back segment, a hip segment, and a leg segment, all rotatably connected by hinges or pivots. When the first bed frame 202 and the second bed frame 104 are joined, the leg-raising, leg-lowering, back-raising, and back-lowering movements of the first bed frame 202 can simultaneously cause the second bed frame 104 to perform the same movements.

[0074] It is important to note that since the movable bed 200 is designed for a wheelchair-like working posture, the corresponding leg sections on the first bed frame 202 need to be able to lower their legs. Furthermore, when the movable bed 200 is joined with the fixed bed 100 to form a nursing bed, the entire nursing bed also needs to accommodate leg-raising movements. Specifically, a suitable movable bed 200 should be selected, with leg sections capable of raising, lowering, and lying flat.

[0075] In addition, the movement of the back section and the leg section of the movable bed 200 is independent. That is to say, the first bed frame 202 needs to be able to control the lifting of the back section independently, or control the lifting or direction of the leg section independently, or control the movement of the back section and the leg section simultaneously. You can choose from the corresponding models of the movable bed 200.

[0076] In some embodiments of this application, the linkage structure 500 has a separated state and a connected state. When the movable bed 200 and the fixed bed 100 are in a spliced ​​state, and the movable bed 200 is in a lying position and the linkage structure 500 is in a connected state, the movable bed 200 can drive the fixed bed 100 to move through the linkage structure 500. When the linkage structure 500 is in a separated state, the linkage between the movable bed 200 and the fixed bed 100 is released.

[0077] Specifically, the linkage structure 500 has both a separated state and a connected state. When the movable bed 200 and the fixed bed 100 are in a spliced ​​state, the movable bed 200 is in a lying position, and the linkage structure 500 is in a connected state, the movable bed 200 and the fixed bed 100 can move synchronously, allowing the entire bed surface of the nursing bed to perform back lifting, leg lifting, and other movements, eliminating the limitation of the nursing bed's usage area and improving patient comfort.

[0078] When the linkage structure 500 is in a separated state, the movable bed 200 and the fixed bed 100 will not be linked, regardless of their respective positions.

[0079] The state switching of the linkage structure 500 can be achieved through electric control, manual control, or mechanical structure.

[0080] In some embodiments of this application, a linkage structure 500 is provided on one or both of the movable bed 200 and the fixed bed 100. Specifically, the linkage structure 500 may be provided only on the movable bed 200, or only on the fixed bed 100, or both the movable bed 200 and the fixed bed 100 may be provided with linkage structures 500, so that when the movable bed 200 and the fixed bed 100 are in a spliced ​​state, the movable bed 200 can drive the fixed bed 100 to move synchronously through the linkage structure 500 and maintain the same posture as the movable bed 200.

[0081] For some embodiments of this application, please refer to Figure 3 , Figures 6 to 9 The linkage structure 500 includes an abutment 501 and an elastic member 502 disposed on the fixed bed body 100. The abutment 501 is slidably disposed on the fixed bed body 100 and can slide relative to the fixed bed body 100 to a first position corresponding to the separated state and a second position corresponding to the connected state. The elastic member 502 acts on the abutment 501 and causes the abutment 501 to tend to slide towards the second position. The upper end of the abutment 501 has a guide surface 503. When the movable bed body 200 and the fixed bed body 100 are joined together, and during the process of the movable bed body 200 switching from the working state to the lying position, the movable bed body 200 abuts against the guide surface 503 and pushes the abutment 501 to slide from the second position to the first position. When the movable bed body 200 and the fixed bed body 100 are connected by the linkage structure 500, a portion of the movable bed body 200 is located below the abutment 501.

[0082] More specifically, please see [link to relevant documentation]. Figure 6 , Figure 7 , Figure 8 and Figure 9 The movable bed 200 has a first bed frame 202, and the fixed bed 100 has a second bed frame 104. An abutment 501 and an elastic member 502 are disposed on the second bed frame 104. The abutment 501 is slidably disposed on the second bed frame 104 and can slide relative to the second bed frame 104 to a first position and a second position. The first bed frame 202 can switch between a lying position and a working position.

[0083] For example, when the first bed frame 202 is in a working position and connected to the second bed frame 104, if the first bed frame 202 needs to lift the back of the second bed frame 104, the back section of the first bed frame 202 is above the second bed frame 104. At this time, the back section of the first bed frame 202 cannot lift the back section of the second bed frame 104. Simultaneously, after the first bed frame 202 is connected to the second bed frame 104, the first bed frame 202 needs to be switched to a flat position to form a larger bed surface.

[0084] In the embodiments of this application, combined with Figure 8 and Figure 9 When the back section of the first bed frame 202 rotates from top to bottom, it will first contact the guide surface 503 and push the abutment 501 to slide, so that the first bed frame 202 can rotate to below the abutment 501. At this time, the abutment 501 slides to the second position under the action of the elastic member 502. When the back section of the first bed frame 202 performs a back-lifting action, it can push the abutment 501 to move upward, and at the same time drive the back section of the second bed frame 104 to perform a back-lifting action.

[0085] Of course, the leg section of the second bed frame 104 can also be equipped with abutment 501 and elastic member 502, so that when the leg section of the first bed frame 202 is in the raised state, it can also rotate to the underside of the leg section of the second bed frame 104, and when the leg section of the first bed frame 202 is raised, it will drive the leg section of the second bed frame 104 to lift upward.

[0086] In some other embodiments of this application, the linkage structure 500 is disposed on the movable bed body 200. Similarly, the linkage structure 500 includes an abutment member 501 and an elastic member 502.

[0087] The difference between the linkage structure 500 mounted on the fixed bed 100 and the linkage structure 500 mounted on the movable bed 200 is that the abutment member 501 is slidably disposed on the movable bed 200, and the lower end of the abutment member 501 has a guide surface 503. The abutment member 501 can slide relative to the movable bed 200 to a first position corresponding to the separated state and a second position corresponding to the connected state. The elastic member 502 acts on the abutment member 501, causing the abutment member 501 to tend to slide towards the second position.

[0088] Although not illustrated, it is understood that the movable bed 200 and the fixed bed 100 are joined together, and during the transition of the movable bed 200 from the working state to the lying position, the fixed bed 100 abuts against the guide surface 503, pushing the abutment member 501 to slide from the second position to the first position. When the movable bed 200 and the fixed bed 100 are connected by the linkage structure 500, a portion of the fixed bed 100 is positioned above the abutment member 501.

[0089] In existing nursing beds, the first bed frame 202 must be moved to the side of the fixed bed body 100 in a supine position before it can be spliced ​​with the second bed frame 104 to form a larger bed surface. If the first bed frame 202 is moved to the side of the second bed frame 104 in a working position, it cannot switch from a working position to a supine position due to the interference and restriction of the structure of the second bed frame 104, and thus cannot form a larger bed surface.

[0090] Such restrictions require the mobile bed 200 to be switched to a supine position before it can be transferred to the side of the fixed bed 100. Consequently, the patient is transferred in a supine position before being transferred to the side of the fixed bed 100, which may cause the patient to feel ashamed and affect their mental health.

[0091] In this application, by setting the linkage structure 500, after the first bed frame 202 moves to the side of the second bed frame 104 in a working posture, the first bed frame 202 will not interfere with or collide with the second bed frame 104 when it switches to a lying posture. Furthermore, the linkage structure 500 can also connect the first bed frame 202 and the second bed frame 104, so that when the first bed frame 202 switches from a lying posture to a working posture, it drives the second bed frame 104 to move synchronously, so that the second bed frame 104 and the first bed frame 202 maintain the same posture.

[0092] In some embodiments of this application, the movable bed 200 is provided with a control module (not shown in the figure), which is used to control the movable bed 200 to switch between a lying position and a working position. The control module has a first interface 201, and the fixed bed 100 has a second interface 103. The second interface 103 is electrically connected to an external power source. When the movable bed 200 and the fixed bed 100 are joined together, the first interface 201 and the second interface 103 are electrically connected, and the external power source supplies power to charge the control module.

[0093] Please continue reading Figure 4 and Figure 5 The first interface 201 of the control module is located on the side of the movable bed 200 facing the fixed bed 100, and is used to make electrical connection with the corresponding interface on the fixed bed 100, namely the second interface 103, when the movable bed 200 and the fixed bed 100 are spliced ​​together.

[0094] Understandably, the second bed frame 104 is usually fixed to the ground or mounted on the wall of the ward.

[0095] It is also understood that the control module can be located inside or at the bottom of the movable bed 200, and may include a controller, memory, drive circuit, and multiple actuators such as electric push rods or hydraulic cylinders. The control module drives the relative movement of each frame segment of the first bed frame 202 by controlling the extension or rotation of each actuator, thereby realizing the switching of the movable bed 200 between the working posture and the lying posture, as well as specific actions such as raising and lowering legs, raising and lowering the backrest.

[0096] In this embodiment, the second interface 103 of the fixed bed 100 serves not only as a signal transmission interface but also as a power transmission interface. The electrical connection lines in the first interface 201 and the second interface 103 include signal transmission lines and power transmission lines. The second interface 103 can be electrically connected to an external power source, such as an AC power socket in the ward or other power supply system, via a power cable embedded inside the fixed bed 100. The electrical energy provided by the external power source is transmitted to the second interface 103 via the power cable, and then, through the electrical connection between the second interface 103 and the first interface 201, the control module is powered and charged.

[0097] It is understandable that when the movable bed 200 is separated from the fixed bed 100, the first interface 201 and the second interface 103 are electrically disconnected. At this time, the control module of the movable bed 200 can be powered by the energy stored in its internal rechargeable battery to maintain the posture switching function of the movable bed 200 after separation from the fixed bed 100. When the movable bed 200 is moved back to the accommodating space 101 of the fixed bed 100 and spliced ​​together, the first interface 201 and the second interface 103 are electrically reconnected, and the external power supply charges the control module to replenish the energy consumed by the movable bed 200 during its separation. In this embodiment, by using the second interface 103 as a power transmission interface, the charging function of the movable bed 200 in the spliced ​​state is realized, eliminating the need for a separate charger or charging dock for the movable bed 200. This is convenient to use and ensures the continuous power supply capability of the movable bed 200 in the separated state.

[0098] In a further embodiment of this application, the fixed bed 100 is provided with a turning mechanism 102 for driving the fixed bed 100 and the movable bed 200 to turn over. After the first interface 201 and the second interface 103 are electrically connected, the control module is used to control the turning mechanism 102 to drive the fixed bed 100 and the movable bed 200 to turn over.

[0099] Specifically, the turning mechanism 102 can be installed inside or at the bottom of the second bed frame 104, and its power output end is connected to the second bed frame 104 to drive the second bed frame 104 to perform a turning action. After the first bed frame 202 and the second bed frame 104 are joined together, the turning mechanism 102 can drive the first bed frame 202 and the second bed frame 104 to perform a bidirectional turning action.

[0100] It should be noted that the specific implementation methods of the first bed frame 202 to perform actions such as lifting legs and back, and the turning mechanism 102 to drive the first bed frame 202 and the second bed frame 104 to perform turning actions, can all adopt the traditional methods of lifting legs, back, and turning over, and this application does not limit them.

[0101] Furthermore, the power input terminal of the turning mechanism 102 is electrically connected to the second interface 103, that is, the turning mechanism 102 receives control signals and / or power supply through the second interface 103. The second interface 103 is located on the side of the fixed bed 100 facing the movable bed 200, and its position corresponds to the position of the first interface 201.

[0102] In traditional nursing beds, once the movable bed body 200 is separated from the fixed bed body 100, the movable bed body 200 is disconnected from the original wiring of the nursing bed. Consequently, when the movable bed body 200 needs to be switched in position, it requires manual external force, which is time-consuming and laborious, and may even be difficult to switch positions when the patient is using it alone. At the same time, the position switching of the fixed bed body 100 usually requires independently configured control circuits and drive units, resulting in a complex electrical control system and high manufacturing costs for the nursing bed.

[0103] In this embodiment, when the movable bed 200 enters the accommodating space 101 of the fixed bed 100 and is assembled with the fixed bed 100, the first interface 201 and the second interface 103 are electrically connected to each other. At this time, the control module on the movable bed 200 is electrically connected to the turning mechanism 102 on the fixed bed 100 through the electrical connection established by the first interface 201 and the second interface 103. The control signal output by the control module can be transmitted to the power input end of the turning mechanism 102 via the first interface 201 and the second interface 103, thereby controlling the operation of the turning mechanism 102 and driving the second bed frame 104 to switch postures.

[0104] In other words, in the assembled state, the patient can control the posture switching of the movable bed 200 itself by operating the control module on the movable bed 200, such as by operating the control panel, remote control or voice commands, and can also control the posture switching of the fixed bed 100, realizing centralized control of the two beds by one control module.

[0105] In summary, the nursing bed provided in this application, by setting the control module on the movable bed body 200, allows the movable bed body 200 to independently switch postures even after being separated from the fixed bed body 100, primarily switching between working and lying postures without manual intervention. Simultaneously, in the assembled state, the control module can directly drive the turning mechanism 102 through the electrical connection of the first interface 201 and the second interface 103 to achieve posture switching of the fixed bed body 100, realizing one-to-two control, simplifying the electrical control circuitry of the nursing bed, and reducing manufacturing costs.

[0106] Please continue reading Figure 2 and Figure 3 In some embodiments of this application, the fixed bed 100 is equipped with guide rollers 300, and / or the movable bed 200 is equipped with guide rollers 300. That is, guide rollers 300 are provided on one or both of the fixed bed 100 and the movable bed 200. The guide rollers 300 guide the fixed bed 100 and the movable bed 200 when they approach each other and when they move away from each other, improving the stability of the movable bed 200 relative to the fixed bed 100 during movement, and at the same time improving the docking accuracy of the first interface 201 and the second interface 103. The number and position of the guide rollers 300 can be designed according to actual installation requirements, and this application does not limit them.

[0107] Please combine Figure 4 and Figure 5 As shown, in some embodiments of this application, the nursing bed further includes a limiting structure 400. The fixed bed body 100 and / or the movable bed body 200 are equipped with the limiting structure 400, that is, the limiting structure 400 is disposed on one or both of the fixed bed body 100 and the movable bed body 200. The limiting structure 400 has a first state and a second state. When the limiting structure 400 is in the first state, the fixed bed body 100 and the movable bed body 200 are locked together. When the limiting structure 400 is in the second state, the locking between the fixed bed body 100 and the movable bed body 200 is released. At this time, the movable bed body 200 can be separated from the fixed bed body 100 and become independent of each other.

[0108] Specifically, in this embodiment, the limiting structure 400 is used to lock the movable bed 200 and the fixed bed 100 together after they are spliced ​​together, to prevent the movable bed 200 from accidentally detaching from the fixed bed 100; or, after the movable bed 200 and the fixed bed 100 are separated, to prevent the movable bed 200 from accidentally sliding into the accommodating space 101.

[0109] For example, the limiting structure 400 uses a locking tongue provided on the movable bed body 200. When the movable bed body 200 and the fixed bed body 100 are in the spliced ​​state, the locking tongue extends, thereby preventing the movable bed body 200 from sliding out of the accommodating space 101. Of course, in other embodiments, the limiting structure 400 may also use a pin-type locking structure or an electromagnetic locking structure, which is not limited in this application.

[0110] Furthermore, the control module is electrically connected to the limiting structure 400 and is used to control the limiting structure 400 to switch between a first state and a second state. Specifically, the control module can send commands to the limiting structure 400. When it is necessary to separate the movable bed 200 and the fixed bed 100, the control module controls the limiting structure 400 to switch to the second state, so that the movable bed 200 can move and separate relative to the fixed bed 100. The control module can control the limiting structure 400 in various ways, such as buttons on the control panel, buttons on the remote control, or through relevant voice commands, etc., which are not limited in this application.

[0111] In this embodiment, by electrically connecting the limiting structure 400 to the control module, and more specifically, by using the driving component of the limiting structure 400, such as a motor that drives the locking tongue or an electromagnet that drives electromagnetic movement, the limiting structure 400 is electrically controlled. The user can lock and unlock the movable bed 200 and the fixed bed 100 without manually operating the limiting structure 400, making the operation convenient and quick.

[0112] This application also provides a control method for a nursing bed, used to control the posture switching of the nursing bed as described in any of the above embodiments. The control method specifically includes the following steps:

[0113] S100: Obtaining user needs;

[0114] S101: Obtain the splicing status information of the fixed bed 100 and the movable bed 200;

[0115] S102: Determine whether the splicing status of the fixed bed 100 and the movable bed 200 meets the user's needs;

[0116] If satisfied, proceed to step S103;

[0117] Otherwise, adjust the splicing posture of the fixed bed 100 and the movable bed 200 to meet the user's needs before proceeding to step S103.

[0118] S103: Obtain the attitude information of the fixed bed 100 and the movable bed 200;

[0119] S104: Determine whether the postures of the fixed bed 100 and the movable bed 200 meet the user's requirements;

[0120] If satisfied, proceed to step S106;

[0121] Otherwise, proceed to step S105:

[0122] S105: The movable bed 200 and the fixed bed 100 can switch postures to meet user needs;

[0123] S106: Repeat step S100.

[0124] For example, please see Figure 13 In this embodiment, the user's back-lifting request is obtained, and it is determined whether a back-lifting signal has been received, that is, whether the patient has entered the back-lifting operation on the control panel, or pressed the back-lifting button, or entered a voice command to control the back-lifting.

[0125] Furthermore, the movable bed 200 is equipped with a control module, which is used to control the movable bed 200 to switch between a lying position and a working position; the fixed bed 100 is equipped with a turning mechanism 102 for driving the fixed bed 100 and the movable bed 200 to turn over. The control module has a first interface 201, and the fixed bed 100 has a second interface 103. When the movable bed 200 and the fixed bed 100 are spliced ​​together, the first interface 201 and the second interface 103 are electrically connected, and the control module is used to control the turning mechanism 102 to drive the fixed bed 100 and the movable bed 200 to perform turning actions.

[0126] Before the control module controls the movable bed 200 to switch positions, it determines whether the movable bed 200 and the fixed bed 100 are in a supine position. If so, the control module controls the movable bed 200 to perform leg raising, leg lowering, back raising, or back lowering actions; otherwise, the control module controls the turning mechanism 102 to switch both the movable bed 200 and the fixed bed 100 to a supine position before controlling the movable bed 200 to perform the same actions. Before the control module controls the turning mechanism 102 to drive the movable bed 200 and the fixed bed 100 to perform a turning action, it determines whether the movable bed 200 is in a supine position; if so, the control module controls the turning mechanism 102 to drive the movable bed 200 and the fixed bed 100 to perform the turning action; otherwise, the control module controls the movable bed 200 to switch to a supine position before controlling the turning mechanism 102 to drive the movable bed 200 and the fixed bed 100 to perform the turning action.

[0127] For example, if a back-lifting signal is received, the system first determines whether the fixed bed frame 100 and the movable bed frame 200 are in a separated state. If the fixed bed frame 100 and the movable bed frame 200 are in a separated state, the control module can drive the movable bed frame 200 to perform a back-lifting action without considering the fixed bed frame 100, and therefore without considering whether it is in a rolling position. That is, when the fixed bed frame 100 and the movable bed frame 200 are in a separated state, the control module directly drives the movable bed frame 200 to perform a back-lifting action.

[0128] Specifically, if the fixed bed frame 100 and the movable bed frame 200 are in the splicing state, it is necessary to first determine whether the bed is in the turning-over state. If it is in the turning-over state, it is necessary to switch the turning-over state to the flat lying state before performing the back lifting action.

[0129] It is understandable that the difference between the back descent action and the back lift action is that the user demand received is a back descent demand, and the signal received is a back descent signal.

[0130] Similarly, please see Figure 14 In this embodiment, the leg-raising motion is essentially the same as the back-raising motion. It should be noted that, please combine... Figure 15 Since the leg section of the movable bed 200 will also have a leg-raising action, that is, when the leg section is in the lying position, it is necessary to determine whether the leg is in a horizontal position during the leg-raising process. If the leg is in a horizontal position, it is necessary to receive a leg-raising signal again to perform the leg-raising action again.

[0131] It is also understandable that the difference between leg lowering and leg raising is that the user demand received is a leg lowering demand, and the signal received is a leg lowering signal.

[0132] Please see Figure 16 In this embodiment, the movable bed 200 also needs to switch directly from a lying position to a wheelchair position. Specifically, it receives an instruction, namely a chair-forming signal (also known as a one-click chair-forming signal), to simultaneously or sequentially perform back-raising and leg-lowering movements.

[0133] Similarly, please see Figure 17 The movable bed 200 also has the requirement to switch directly from the working posture of a wheelchair to a lying posture. Specifically, it receives an instruction, namely the bed-forming signal (also known as the one-click bed-forming signal), to simultaneously or sequentially execute the back lowering action (or back flattening action) and the leg lowering action (or leg flattening action).

[0134] Please see Figure 18In some embodiments of this application, users may also have the need to turn over, and the turning mechanism (i.e., the turning mechanism 102) needs to be controlled and driven by the control module. When the movable bed 200 and the fixed bed 100 are in a spliced ​​state, the control module will control the movement of the turning mechanism through the first interface 201 and the second interface 103.

[0135] Before the control module controls the turning mechanism 102 to drive the first bed frame 202 and the second bed frame 104 to perform a turning action, it determines whether the movable bed 200 is in a supine position. If so, the control module controls the turning mechanism 102 to drive the first bed frame 202 and the second bed frame 104 to perform a turning action; otherwise, the control module controls the movable bed 200 to switch to a supine position (that is, with the back and legs flat) before controlling the turning mechanism 102 to drive the first bed frame 202 and the second bed frame 104 to perform a turning action.

[0136] Please see Figure 19 In a further embodiment of this application, the user may also have an automatic turning-over requirement. Specifically, the user may turn to the left and to the right alternately and at intervals. The interval can be set according to the actual turning-over requirement, and this application does not limit it.

[0137] In this embodiment, please refer to Figure 20 The conditions for exiting automatic rolling over include, but are not limited to, receiving other action signals, receiving an emergency stop signal, or the automatic rolling over action reaching a preset number of times. The preset number of times can be set according to the actual rolling over needs, and this application does not limit it.

[0138] Understandably, only one of these conditions needs to be met to exit the automatic rolling action.

[0139] Please see Figure 21 In some embodiments of this application, there is also a need for bed separation. Specifically, when the nursing bed includes a limiting structure 400, and the control module is electrically connected to the limiting structure 400 to control the limiting structure 400 to switch between a first state and a second state; before the movable bed 200 separates from the fixed bed 100, it is determined whether the fixed bed 100 and the movable bed 200 are in a supine position. If so, the control module controls the limiting structure 400 to switch to the second state; otherwise, the control module controls the movable bed 200 and the fixed bed 100 to switch to a supine state, and then controls the limiting structure 400 to switch to the second state.

[0140] Additionally, it is understandable that after the control module switches the limit structure 400 to the second state, the movable bed 200 may not be separated from the fixed bed 100 for an extended period of time. For example, if the operator still fails to detach the movable bed 200 from the fixed bed 100 after 10 seconds following the control module switching the limit structure 400 to the second state, the control module will switch the limit structure 400 back to the first state. At this point, the movable bed 200 will be reconnected to the fixed bed 100, and the first interface 201 and the second interface 103 will be electrically reconnected.

[0141] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0142] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
