Description

Technical Field

[0001] The present invention relates to medical auxiliary supplies, and particularly to an automated bed especially for patient care. Background Art

[0002] Whether in life or in medical care, many patients are paralyzed in bed or sedated and analgesic in bed. If lying in bed for a long time, it will cause pressure sores. However, if turning over, a large amount of manual assistance is required, which is very inconvenient. Especially in the intensive care unit, patients with severe ARDS need prone ventilation, which requires the collaborative cooperation of many medical staff. At least four people are needed to turn over, and there is a dedicated medical staff to protect the head, and there are dedicated medical staff to ensure multiple intravenous accesses on the body, which requires a large amount of manpower and increases the burden on medical staff. Currently, there are various types of medical beds on the market, mainly used in places such as hospitals, nursing homes, and home care. These beds usually have basic lifting functions to facilitate the care of patients by nursing staff. However, most of the existing medical beds can only achieve simple lifting, lack versatility, and cannot meet the personalized needs of different patients. In addition, the existing patents also involve the design of automated beds, but most of them are still limited to single functions and cannot achieve a variety of complex operations.

[0003] The existing medical beds usually adopt electric or manual methods for adjustment, and the main functions include the lifting of the bed surface height and partial tilting. The electric bed is driven by a motor and can achieve height adjustment within a certain range, but it is still insufficient in functions such as side turning and turning over. Some high-end medical beds have the function of segmented elevation and can independently adjust the upper body or lower body of the patient, but these beds are expensive, have complex operations, and are not convenient to use.

[0004] In addition, there are also certain deficiencies in the stability and safety of the existing bed body. Especially when performing large side turning or 180-degree turning over, the stability of the existing bed is insufficient, which may cause the patient to fall or get injured, increasing the nursing risk. Or because although the traditional restraint belt has a good binding effect, due to its own gravity during the turning process of the bed body, it is very easy to cause the patient to be strangled by the restraint belt or have great discomfort.

[0056] Figure 1 The structural schematic diagram of a turning-over bed provided by this embodiment;

[0057] Figure 2 The turning structural schematic diagram of a turning-over bed provided by this embodiment. Detailed Embodiment

[0058] The present invention can implement various changes and can have various embodiments. Therefore, specific embodiments are illustrated in the drawings and described herein. However, this is not to limit the present invention to a specific embodiment, but should be understood to include all changes, equivalents and alternatives falling within the spirit and technical scope of the present invention.

[0059] As Figure 1 shown, this embodiment provides a turning-over bed for realizing the turning-over of a patient, which includes a bed frame 100, a turning-over bed frame body 210, a turning-over bed body 220 and an observation board body 300;

[0060] The bed frame 100 is the support frame of the entire turning-over bed, and its shape can be designed according to the shape of the bed body itself. In this experimental example, a simplest frame structure is provided, which includes four columns 110 with wheels, and a bottom frame 120 connecting the columns 110;

[0061] The turning-over bed frame body 210 is a frame structure, and its four corner ends are provided with sliders 211. The sliders 211 are embedded in the sliding grooves 111 of the columns 110 and are arranged to be relatively slidable. The slider 211 is connected with a mechanism 112 such as a cylinder or a hydraulic cylinder that can realize the lifting function. Under its action, the slider 211 is driven to perform reciprocating motion in the vertical direction along the sliding groove 111. Thereby driving the entire turning-over bed frame body 210 to perform reciprocating motion in the vertical direction.

[0062] As Figure 2As shown, the turning bed body 220 includes a main shaft that constitutes the length direction of the entire turning bed body, that is, a rotating shaft 221. Both ends of the rotating shaft 221 are respectively mounted on the turning bed frame 210 through the toothed through holes 212 at the head end and the through holes 213 at the tail end of the turning bed frame 210. The two ends of the rotating shaft 221 are respectively gear-shaped, with a head end 2211 that meshes with the toothed through hole 212 and a tail end 2212 that can pass through the through hole 213. To avoid the problem of the rotating shaft 221 slipping during the movement or motion of the bed body, the diameters of the parts of the head end and the tail end protruding from the frame are larger than the inner diameters of the toothed through hole 212 and the through hole 213.

[0063] The above-mentioned rotation process can generally be achieved by driving the shaft to rotate with a traditional rotating motor. However, when power is unavailable (such as in some emergency medical environments), the head end 2211 also has a handle 2213. By rotating the handle, the effect of manually controlling the rotation can be achieved.

[0064] In addition, in order to evaluate the level of the bed board in the rotating state, a level can also be installed on the rotating shaft body. The driving motor can judge whether the rotation angle is in place according to the level accuracy transmitted back by the level. In the manual case, the rotation angle can be judged manually according to the liquid level shown by the level.

[0065] In addition, to avoid the problem of the bed board flipping caused by motor failure or accidental touch of the handle by someone.

[0066] The turning bed frame 210 also has a limiting mechanism 214. The limiting mechanism is a rotatable top plate, which can be arranged on one side or both sides of the turning bed frame 210. When the bed board rotates to the in-place position, by rotating the top plate in the direction shown in the figure, the position of the bed board can be limited.

[0067] The turning bed body 220 is also provided with a restraint mechanism for restraining the patient on the turning bed body to avoid falling during the turning process and to achieve the effect of hanging the patient when necessary;

[0068] In this embodiment, two restraint schemes are designed, which can be adjusted according to needs in actual use. Among them,

[0069] Scheme 1 is: the restraint mechanism includes a plurality of straps;

[0070] The number of the straps is set according to actual use needs. Generally, it includes 3 groups, corresponding to the human head, torso, and lower limb parts respectively. Considering comfort, the straps are wide-band-shaped bodies.

[0071] The strap is made of a material and has a structure similar to that of a vehicle seat belt, that is, it is a retractable structure. One end of it is fixed (by traditional fixing methods such as sewing, welding, bonding, screwing, etc.) to the first side edge of the turning-over bed body, and the other end is a plug, that is, in the shape of a plug of a vehicle seat belt; the second side edge of the turning-over bed body has a plurality of sockets (that is, sockets of a vehicle seat belt). During use, after pulling out the safety strap in the winch by pulling, the plug at the head end of the strap is inserted into the socket. Due to the built-in winch, it automatically retracts and tightens, realizing the binding of the patient.

[0072] The second solution is as Figure 1 shown, the restraint mechanism is an inflatable structure, including a face air cushion 231, a torso air cushion 232, and a lower limb air cushion 233;

[0073] Both ends of the face air cushion 231, the torso air cushion 232, and the lower limb air cushion 233 are connected with retractable ropes 2311 with adjustable lengths (such as a retractable strap structure), so that it can be adjusted according to the patient's body size. The end of the retractable rope 2311 is a snap fastener 2312, and the snap fastener matches the socket 201 on the turning-over bed body 220 (similar to the structure of the seat belt socket of various facilities with safety protection requirements such as airplanes).

[0074] In the middle of the face air cushion 231, that is, the patient's face, there is a through-hole 2313 structure.

[0075] Regarding the air cushion structure, it can effectively alleviate the bruise problem caused by excessive local force during the patient's turning-over process (for example, for obese, young children, and people with sensitive skin, if they are restrained by straps, problems such as blood stasis and pain will occur in a very short time). And the air cushion is similar to the bed body, which can make the patient feel better after turning over. If there is a need for lying down for a short time, the air cushion can even be used instead of the quilt, greatly reducing the cleaning cost and labor output.

[0076] The observation board 300 is installed directly below the turning-over bed body 200. One side facing the turning-over bed body can be a mirror, or monitoring devices similar to a monitoring probe 301 can be installed, so that it is convenient for medical staff to directly observe the patient's situation, without specifically assigning medical staff to squat down and probe to observe the patient's situation, reducing the physical pressure on medical staff.

[0077] Considering that the patient needs to lie prone for a long time after turning over, the observation board 300 also has the function of moving up and down to support the patient. Sliders 310 are provided at the four corner ends of the observation board 300. The sliders 310 are embedded in the sliding grooves 111 of the upright columns 110 and are arranged to be slidable relative to each other. The slider 310 is connected to a mechanism 320 such as a cylinder or a hydraulic cylinder that can realize the lifting function. Under its action, the slider 310 is driven to perform a reciprocating motion in the vertical direction along the sliding groove 111, thereby driving the entire observation board 300 to perform a reciprocating motion in the vertical direction.

[0078] Considering that it is still difficult for medical staff to observe the patient's expression and pressure conditions when the patient is supported by the observation board, in this embodiment, one or more cameras can also be installed on the bottom frame 120 to observe the patient in all directions.

[0079] A reserved through hole 302 is provided at the position of the observation board 300 relative to the patient's head. Generally speaking, in order to meet the usage needs of patients with different head positions, the reserved through hole 302 is set relatively large, and a washer is embedded therein. The washer is shaped like a sealing ring and can be directly embedded in the through hole, and can also be easily disassembled, cleaned and replaced. When the patient's head position is relatively small, the through hole diameter can be reduced by simply embedding a washer with a larger thickness. Moreover, the design of the washer can place the patient's face on it to avoid being crushed.

[0080] Considering the problem that the head positioning of the patient after turning over needs to be consistent up and down, the turning bed body 220 also has a positioning ring 202. Before turning over, the patient's head should be placed at the center of the fixed circle of the positioning ring, so that it will just fall on the reserved through hole 302 after turning over.

[0081] Considering the need for the convenience of equipment use, the turning bed in the above embodiment also includes a central control system. The central control system is electrically connected to each component of the bed body and has a front-end display device.

[0082] Specifically, the turning bed can be configured with multiple motor devices. For example, the turning bed body is driven by a first motor to rotate at a specified angle, that is, the motor is docked with the rotating shaft to drive the rotating shaft to rotate. In addition, the current rotation angle of the turning bed can be quickly judged based on the change of the level installed on the turning bed body, so as to judge the end point of the rotation;

[0083] The restraint mechanism, i.e., the winch or the retractable belt, is driven by the second motor to relax or tighten the safety belt. In addition, the restraint intensity on the patient can be judged based on the pressure value of the pressure sensor installed on the restraint mechanism, and the tightness can be adjusted accordingly; a camera is installed on the observation panel to send the image data of the patient to the screen at the front end of the device for display in real time; a massager is installed on the turning bed body, and the massager can be controlled to massage in a specified manner at the front end of the device.

[0084] In addition, the up and down movement of the turning frame body and the observation panel can also be achieved by a motor.

[0085] The above-mentioned devices such as motors are all controlled by the central control system, and the user can control and observe on the interface at the front end of the device.

[0086] In addition, for safety considerations, on the turning bed frame body, the bottom surface corresponding to the horizontal state of the turning bed body has a foldable support frame, which can be folded manually or popped out by a motor.

[0087] Although the above has been described centered on the embodiments, this is only an illustration and does not limit the present invention. Those of ordinary skill in the art will understand that various deformations and applications not illustrated above can be made without departing from the essential characteristics of this embodiment. For example, each component specifically shown in the embodiment can be implemented after being deformed. Moreover, the various differences related to such deformations and applications should be interpreted as being included in the scope of the present invention defined in the appended claims.
