Description

Technical Field

[0001] The present invention relates to a device for turning over, and particularly to a mobile turning-over device. Background Art

[0002] Patients or those in need of care require assistance from medical staff, relatives, etc. to turn over when lying in bed for a long time or suffering from diseases (such as chronic obstructive pulmonary disease, etc.).

[0003] Typically, for example, chronic obstructive pulmonary disease (COPD), the full name is chronic obstructive pulmonary disease, and its main pathological feature is the obstruction of airway ventilation, which hinders the discharge of airway secretions, causing inflammatory reactions in the lungs, and has the characteristics of incomplete reversibility and progressive development. COPD has the highest incidence rate in people over 45 years old. Chronic dyspnea, cough with sputum, chest tightness and shortness of breath, and easy anxiety and fatigue are the main clinical symptoms of COPD, seriously affecting the quality of life of patients. Some severe COPD patients often experience a decrease in blood oxygen saturation and dyspnea in the supine position. At this time, turning over from the supine position to the prone position in a timely manner can effectively relieve the oxygen saturation and implement effective rescue for severe patients, which is of great significance to the treatment quality of patients.

[0004] Currently, in most hospitals, families and other scenarios, for the operation from the supine position to the prone position, basically the traditional method of manual turning over is still used, which has low efficiency, consumes a lot of manpower, and the effect is not ideal. Especially in hospitals, when encountering patients with extremely heavy physiques, often 5 - 6 people are needed, seriously wasting precious human resources; and some beds that can assist in turning over have complex structures, not only with high costs, but also troublesome to use, and cannot be used for mobile use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0037] Embodiment

[0038] As Figures 1-5 shown, this embodiment provides a mobile turning device, including a wrapping structure 200, a first adjustment mechanism 300 and a second adjustment mechanism 400. Among them, the first adjustment mechanism 300 and the second adjustment mechanism 400 are arranged opposite to each other to realize the adjustment of the wrapping mechanism 200. In this embodiment, the wrapping structure 200 includes canvas.

[0039] Specifically, the wrapping structure 200 is disposed under the sheet 202. Among them, the wrapping structure 200 is respectively connected to the first adjustment mechanism 300 and the second adjustment mechanism 400. After being rolled up, the wrapping structure 200 forms a receiving portion 201, and the receiving portion 201 forms an activity space for the sheet 202. Since the first adjustment mechanism 300 and the second adjustment mechanism 400 can adjust the position of the wrapping mechanism 200, the angle of the human body 203 in the sheet 202 is also adjusted, realizing flipping;

[0040] More specifically, the bottom surface of the wrapping structure 200 has at least one set of first connecting members 204 and at least one set of second connecting members 205. Among them, the first connecting members 204 are connected to the first adjustment mechanism 300, and the second connecting members 205 are connected to the second adjustment mechanism 400.

[0041] As a preferred example 1, the first adjustment mechanism 300 and the second adjustment mechanism 400 are preferably composed of lifting devices. Specifically:

[0042] The first adjustment mechanism 300 includes two relatively arranged lifting devices. Among them, the lifting device includes a base 501 and a lifting mechanism 502 installed on the base 501;

[0043] The top end of the lifting mechanism 502 is a mounting seat 503. A rotating mechanism 504 is installed between the mounting seats 503, and the transmission mechanism 505 on the rotating mechanism 504 is connected to the first connecting member 204.

[0044] The second adjustment mechanism 400 includes two relatively arranged lifting devices. Among them, the lifting device includes a base 501 and a lifting mechanism 502 installed on the base 501; the top end of the lifting mechanism 502 is a mounting seat 503. A rotating mechanism 504 is installed between the mounting seats 503, and the transmission mechanism 505 on the rotating mechanism 504 is connected to the second connecting member 205;

[0045] The spacing between the lifting devices of the second adjustment mechanism 400 is smaller than the spacing between the lifting devices of the first adjustment mechanism 300. The core design of the smaller spacing between the lifting devices of the second adjustment mechanism 400 compared to that of the first adjustment mechanism 300 lies in adapting to the mechanical requirements and movement trajectories of different parts of the human body during the turning-over process. Specifically, the wider spacing between the two lifting devices of the first adjustment mechanism 300 corresponds to the support range of the upper back area of the human body, enhancing the stability control of the bedsheet and the wrapping structure 200 during the initial turning stage through a larger span; while the second adjustment mechanism 400 adopts a more compact spacing between the lifting devices, which adapts to the movement characteristics of the human waist and hip areas - when the wrapping structure 200 is curled to a vertical state, the narrow spacing of the second adjustment mechanism 400 can reduce the occupation of the patient's lower limb space, and at the same time, through the dense transmission force distribution (such as the traction path of the transmission belt 505), precise angle adjustment of the lower body can be achieved. Under the synergistic action of the transmission mechanism (belt / conveyor belt) and the rotating mechanism (tubular motor), this differential design can not only avoid the offset problem caused by uneven force during the turning-over action of the upper and lower bodies, but also optimize the overall structural layout of the device to adapt to the portability requirements during the movement of multiple beds.

[0046] As a preferred example 2, the second adjustment mechanism 400 is foldably installed on the bed board 100, improving the space adaptability of the device and the device transfer efficiency. Specifically, the lifting devices (base 501 + lifting mechanism 502 + rotating mechanism 504) of the second adjustment mechanism 400 form a dynamic connection with the side edge or bottom surface of the bed board 100 through a hinge or rotating shaft structure - in the non-working state, the lifting mechanism 502 can be folded along the axis to a storage position parallel to the plane of the bed board 100 (such as fitting along the outer edge of the bed board or being stored below), thereby reducing the overall occupied space of the device; when a turning operation needs to be performed, the second adjustment mechanism 400 can be unfolded to the working position. At this time, this example does not require a mounting pin because it is already rigidly connected to the bed board and has stability. This folding mechanism and the moving wheels 508 form a collaborative design: after the device is moved to a new bed, the second adjustment mechanism 400 quickly completes the deployment through the unfolding action, avoiding the cumbersome process of repeated disassembly and assembly of traditional fixed mechanisms; when folding and storing, the lifting mechanism 502 minimizes the space occupation of the tail or side of the bed board 100, not only maintaining the normal area for nursing operations around the hospital bed, but also ensuring that the moving wheels 508 of the carrier plate 507 are not obstructed during the pushing and pulling process. Further, the folding structure of the second adjustment mechanism 400 adapts to its precise adjustment requirements for the human waist and hip areas: its narrower spacing between the lifting devices is easier to align with the geometric boundary of the bed board 100 during folding, and still provides sufficient torque to ensure the force reliability of the wrapping structure 200 and the transmission belt 505 during the turning of the lower body after unfolding. During implementation, the operator can complete the switching between the folded / unfolded states manually or electrically, taking into account both the action efficiency of the device and the immediacy requirements of the medical scenario (see Figure 1and the process description for multi-bed use in the embodiments); the bed board 100 is used to place the wrapping structure 200.

[0047] In Preferred Examples 1 and 2, preferably, the rotating mechanism 504 includes a tubular motor, and the transmission mechanism 505 includes a belt or a conveyor belt. This enables efficient and low-noise power transmission and flexible traction control. Specifically, the tubular motor is directly nested between the mounting seats 503 of the two lifting devices in a hollow cylinder structure (see the schematic layout of the rotating mechanism in Figure 1 and 4 ). Its integrated design eliminates the need for additional brackets for fixation, reducing the overall volume of the device and enabling the synchronous drive of the transmission mechanisms 505 at both ends through the rotation of the motor cylinder. The transmission mechanism 505 is preferably made of a belt or a conveyor belt material (such as rubber, nylon-reinforced belt, etc.) and is connected to the output shaft of the tubular motor through a pressure wheel or a gear to form a continuous annular traction path - the characteristics of this flexible wire enable the first connecting member 204 and the second connecting member 205 of the wrapping structure 200 to be linearly dragged along a preset track during the turning operation, reducing the risk of motion interference caused by a rigid robotic arm and buffering the force on the human body 203 through the extensibility of the soft material. In this solution, the high torque output capacity of the tubular motor meets the driving requirements for the wrapping structure 200 and the human body load during the turning process, such as the instantaneous large torque to overcome static friction during the start-up phase or the precise response ability for angle fine-tuning during the mid-turn. The replaceability and low maintenance cost characteristics of the belt / conveyor belt (compared with chain or gear transmission), combined with the design of the moving wheels 508 of the bearing plate 507, further meet the clinical scenario requirements of the device for high-frequency movement across beds. During implementation, the coordinated operation of the forward / reverse control of the tubular motor and the lifting mechanism 502 can accurately control the curling speed, amplitude, and tension distribution of the wrapping structure 200, ensuring the safety and smoothness of the patient's body position adjustment.

[0048] The base 501 is provided with mounting pins 506 for connecting corresponding mounting holes 102 on the bed board 100, which facilitates the fixation of the first adjustment mechanism 300 and the second adjustment mechanism 400 to the bed body and can withstand greater forces during operation. Specifically, the mounting pins 506 are embedded in the mounting holes 102 pre-set on the bed board 100 in a cylindrical or conical structure to form an interference fit, or a snap-lock, or a magnetic locking form, effectively preventing the sliding displacement between the base 501 and the bed board 100 during the operation of the lifting mechanism 502. When the rotating mechanism 504 drives the wrapping structure 200 to turn the human body through the transmission mechanism 505, the lateral pulling force and torque generated by the turning-over action can be directly transmitted to the rigid support system of the bed board 100, such as the support 101, through the mounting pins 506, avoiding the risk of mechanism slipping or overturning caused by relying only on the friction force between the base 501 and the contact surface of the bed board. This rigid physical connection method further optimizes the power transmission path of the device: it not only improves the traction efficiency of the first adjustment mechanism 300 for controlling the upper part of the wrapping structure 200, but also ensures that the precise angle adjustment of the lower body by the second adjustment mechanism 400 can be synchronously and stably executed to realize the function description of the synchronism of the lifting device. At the same time, the detachable design of the mounting pins 506 and the mounting holes 102 still retains the mobility of the device - during operation, only the pin-hole connection needs to be released, and then it can be quickly transferred to other beds through the moving wheels 508 for mobile use.

[0049] At least one set of opposite side edges of the wrapping structure 200 is provided with connection buckles. The core design of setting connection buckles on at least one set of opposite side edges of the wrapping structure 200 lies in building the dynamic fixation ability for the patient's body. Specifically, the connection buckles are distributed on the longitudinal edges of both sides of the wrapping structure 200 (such as the left side edge and the right side edge), and adjustable connectors such as hook-and-loop fasteners, snap fasteners or straps are used to achieve symmetric closure. After the bed sheet 202 wraps the human body 203, the operator closes the connection buckles to make the wrapping structure 200 form a cylindrical enclosure structure - this design has two functions: First, when the driving mechanism 505 drives the wrapping structure 200 to curl, the closed state of the connection buckles can prevent the patient from slipping or shifting due to the loosening of the structure; Second, the symmetrically distributed connection buckles can evenly disperse the lateral traction force applied to the wrapping structure 200 during the flipping process to the patient's body surface (see the description of the flipping action in the embodiment), avoiding discomfort caused by excessive local force. At the same time, the first connector 204 and the second connector 205 distributed at the bottom of the wrapping structure 200 are used to connect the transmission belts 505 of the first adjustment mechanism 300 and the second adjustment mechanism 400. The independent design of the side connection buckles allows the wrapping structure 200 to remain mechanically linked with the adjustment mechanism while still being able to open and close quickly to adapt to patients of different body types or to replace the bed sheet during the nursing process. During implementation, medical staff need to fully unfold the wrapping structure 200 and lay it under the bed sheet 202 before turning over. After closing the connection buckles to establish the initial wrapping environment, then start the adjustment mechanism to complete the flipping. This structural feature further ensures the adaptability and stability between the wrapping structure 200 and the patient's body position in the multi-bed switching scenario driven by the moving wheels 508.

[0050] Preferably, the bottom of the base 501 is a bearing plate 507. Among them, the bearing plate 507 is installed with moving wheels 508 for convenient movement; the bottom of the bed board 100 is a support 101 for supporting the ground 000.

[0051] Specifically, in preferred examples 1 and 2, the transmission mechanism 505 is driven to rotate by the rotating mechanism 504. The transmission mechanism 505 of the first adjustment mechanism 300 is located above the wrapping mechanism 200, and the transmission mechanism 505 of the second adjustment mechanism 400 is located below the wrapping mechanism 200, that is, it is usually pressed under the wrapping mechanism 200. When it is necessary to flip the human body 203, first wrap the bed sheet 203 around the human body 203, and then wrap the wrapping mechanism 200 around the bed sheet 203, and use the connection buckles on the wrapping mechanism 200 to fix the wrapping mechanism 200.

[0052] At this time, the first adjustment mechanism 300 is connected to the first connecting member 204, and the second adjustment mechanism 400 is connected to the second connecting member 205. The rotation mechanism 504 of the first adjustment mechanism 300 is controlled to rotate, and the wrapping mechanism 200 and the bed sheet, human body, etc. inside it are driven to turn to the left (from the perspective of looking at the human head) through the transmission mechanism 505. At the same time, the rotation mechanism 504 of the second adjustment mechanism 400 is controlled to rotate, and the wrapping mechanism 200 is driven to shift towards the second adjustment mechanism 400 through the transmission mechanism 505. When the wrapping mechanism 200 is perpendicular to the bed board 100, the two rotation mechanisms 504 continue to operate. At this time, the first adjustment mechanism 300 stops operating, and the rotation mechanism 504 of the second adjustment mechanism 400 continues to operate, driving the wrapping mechanism 200 (the side not connected by the connecting buckle) to continue moving to the right. Then the first adjustment mechanism 300 rotates in the reverse direction to lower the wrapping mechanism 200 to achieve the turning of the human body. When it is necessary to turn back, the above operation is repeated; this process can be manually controlled or automatically controlled by a controller;

[0053] Through the settings of the wrapping mechanism, the first adjustment mechanism and the second adjustment mechanism, the present invention can realize the deflection of the wrapping mechanism driven by the rotation of the rotation mechanism (such as a tubular motor), and complete the turning of the wrapping mechanism and the human body, which is very convenient, saves manpower, and can effectively meet the turning needs of diseases such as chronic obstructive pulmonary disease; it can be used mobilely, and only one set of equipment is required for multiple hospital beds to be rotated for use, reducing the use cost.

[0054] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
