Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to rehabilitation beds and their working methods. Background Technology

[0002] For patients with lower limb fractures and stroke, postoperative lower limb rehabilitation training is essential. A suitable rehabilitation training plan can improve the patient's lower limb muscle strength and help the patient recover normal function as soon as possible. However, in the early postoperative period, patients with lower limb fractures and stroke often have insufficient leg strength. The process of transferring them from the hospital bed to rehabilitation equipment can pull on the wound or joints, easily causing secondary injury.

[0003] CN202821893U discloses a rehabilitation standing training bed, including a bed base frame, a bed frame set on the bed base frame, a mattress board set inside the bed frame, and a foot pedal on the bed frame corresponding to the position of the human feet. A pivot is provided between the bed base frame and the bed frame, and a first telescopic rod is provided between the bed frame and the bed base frame for pushing the bed frame to rotate around the pivot. The first telescopic rod pushes the bed frame to rotate around the pivot so that the person can stand on the foot pedal.

[0004] These types of rehabilitation beds require instructor guidance. Patients need to explain their condition to the instructor, who will then provide training instructions after gaining a thorough understanding of the patient's condition. During training, the patient's facial expressions and verbal descriptions help the instructor determine if the current training is appropriate for the patient's injury. However, both the patient's descriptions and the instructor's understanding are subjective, which can lead to misjudgments of the patient's injury. If the training intensity provided by the instructor is too low, it will prolong the patient's rehabilitation period; if the training intensity exceeds the patient's current tolerance, it will lead to overtraining and secondary injury.

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0020] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0022] refer to Figures 1 to 4 A preferred embodiment of the rehabilitation bed according to this application will be described in detail below. The rehabilitation bed includes a bed body 100, a support base 200, and a drive mechanism 300.

[0023] Specifically, the bed body 100 includes a bed body 110 and a foot rail 120, wherein the foot rail 120 is installed at one end of the bed body 110 and corresponds to the position of the patient's feet. The support base 200 forms a support surface 2001, the bed body 110 is rotatably connected to the support base 200, the drive mechanism 300 is installed on the support base 200, and the bed body 110 is connected to the drive mechanism 300, which drives the bed body 100 to rotate relative to the support base 200.

[0024] Preferably, when the support base 200 is supported on the ground, the support surface 2001 is horizontal.

[0025] When the angle between the bed body 110 and the support surface 2001 is zero, the patient can lie on the bed body 110. The drive mechanism 300 drives the end of the bed body 100 corresponding to the patient's head to rise and the end corresponding to the patient's feet to fall. At this time, the angle between the bed body 110 and the support surface 2001 is greater than zero. The patient can lean against the bed body 110 and stand on the foot railing 120 to perform rehabilitation exercises such as standing on both feet, standing on one foot, and stepping in place. In this way, the patient can be transferred and moved, thereby preventing the patient from suffering secondary injury.

[0026] Preferably, the included angle between the bed body 110 and the support surface 2001 formed by the support base 200 is between zero and ninety degrees.

[0027] As an example, the drive mechanism 300 is implemented to include a cylinder.

[0028] Preferably, multiple straps 130 are provided on both the left and right sides of the bed body 110. Medical staff use the straps 130 to bind the patient to the bed body 110 so that the patient's back is kept in contact with the bed body 110, so as to prevent the patient from falling due to insufficient lower limb strength during training.

[0029] Furthermore, the rehabilitation bed also includes the posture detection component 400 and the controller 500.

[0030] The posture detection component 400 includes two pressure sensors 410, both of which are mounted on the foot rail 120. Both pressure sensors 410 are used to detect the pressure exerted by the patient's lower limbs on the foot rail 120 when the patient is positioned on the bed body 100 and their feet are supported by the foot rail 120, in order to determine the degree of injury to the patient's lower limbs.

[0031] Specifically, because the patient has an injury to his lower limbs, when the patient's feet are on the foot railing 120, the pressure exerted by the injured lower limbs on the foot railing 120 by the patient using the bed body 110 or the healthy lower limbs is less than the pressure exerted on the foot railing 120 in a healthy state, and the greater the difference, the more serious the patient's injury.

[0032] The drive mechanism 300 is controllably connected to the controller 500, and the pressure sensor 410 is communicatively connected to the controller 500. The controller 500 determines the training angle range between the support surface 2001 formed by the bed body 110 and the support seat 200 according to the degree of injury to the patient's lower limbs.

[0033] Understandably, the more severe the patient's injury, the weaker their lower limb strength. Therefore, the initial and final angles within the training angle range determined by the controller 500 are both relatively small, so that the bed body 110 can provide greater support to the patient, avoiding injury caused by insufficient lower limb strength. Conversely, the less severe the patient's injury, the stronger their lower limb strength. Therefore, the initial and final angles within the training angle range formed by the bed body 100 and the support surface 2001 of the support seat 200, determined by the controller 500, are both relatively large, to help the patient recover to normal strength as soon as possible.

[0034] In one embodiment, during the training process, the controller 500 controls the drive mechanism 300 to start intermittently to gradually increase the angle between the support surface 2001 formed by the bed body 110 and the support seat 200. Thus, a single rehabilitation training session is divided into multiple stages, and the support force of the bed body 110 on the patient is gradually reduced during the training of multiple stages, so as to gradually increase the training intensity of the patient, so that the patient's lower limb strength is gradually improved, and the patient recovers as soon as possible.

[0035] To facilitate understanding of the above embodiments by those skilled in the art, an example is given below: the controller 500 determines the training angle range for a patient to be between 45° and 85° based on the severity of the injury to the patient's lower limb. In the first stage of training, the angle between the bed body 100 and the support surface 2001 is 45°, and the patient trains at this angle. After the first stage of rehabilitation training is completed, the drive mechanism 300 continues to drive the bed body 100 to rotate to an angle of 65° with the support surface 2001, and the patient continues training at the current angle. After the second stage of rehabilitation training is completed, the drive mechanism 300 continues to drive the bed body 100 to rotate to an angle of 85° with the support surface 2001, and the patient trains at the current angle until the training is completed.

[0036] Preferably, during training, the controller 500 controls the drive mechanism 300 to swing the bed body 100 relative to the support surface 2001 formed by the support seat 200 within a preset range according to the pressure exerted by the patient's lower limbs on the foot rail 120.

[0037] Specifically, during patient training, the patient's feet rest on the foot railing 120. At this time, the two pressure sensors 410 monitor the pressure exerted by the patient's lower limbs on the foot railing 120 in real time. As training progresses, the patient's lower limb strength gradually weakens. The patient will then consciously shift their center of gravity and actively use their stronger lower limbs for support, while curling up their weaker lower limbs. This causes significant fluctuations in the data measured by the two pressure sensors 410. Based on the monitoring results from the two pressure sensors 410, the controller 500 activates the drive mechanism 300, causing the drive mechanism 300 to rotate the bed body 100 towards the support surface 2001 to increase support for the patient, allowing them to rest. This allows for real-time monitoring of the patient's training behavior during training, preventing overtraining and avoiding secondary injuries. After a predetermined rest period, the controller 500 activates the drive mechanism 300, causing the drive mechanism 300 to rotate the bed body 100 away from the support surface 2001 to continue rehabilitation training.

[0038] Furthermore, the rehabilitation bed also includes a weight sensor 600, which is installed on the bed body 110 or the support base 200 to measure the patient's weight. The weight sensor 600 is communicatively connected to the controller 500. The controller 500 determines the pressure exerted by the patient's two lower limbs on the foot railing 120 in a healthy state based on the patient's weight. The controller then uses this pressure, combined with the pressure exerted by the patient's feet on the foot railing 120 when the patient's feet are positioned on it, to determine the patient's injury. Notably, since the patient's weight changes during recovery, and the weight sensor 600 can measure the patient's weight in real time, the controller 500 can determine the pressure exerted by the patient's two lower limbs on the foot railing 120 in a healthy state based on the patient's real-time weight, thus accurately determining the patient's injury.

[0039] Furthermore, the rehabilitation bed also includes a guide, which is configured to emit instruction signals and is controllably connected to the controller 500. Two pressure sensors 410 detect the pressure exerted by the patient's lower limbs on the foot railing 120 to determine the injured area and recovery level. The controller 500 is configured to control the guide to emit instruction signals based on the injured area and recovery level.

[0040] Specifically, there is a difference in strength between the injured lower limb and the healthy lower limb. The injured lower limb exerts less pressure on the foot railing 120, while the healthy lower limb exerts more pressure, thus allowing the location of the patient's injury to be determined. The smaller the pressure difference between the two pressure sensors 410, the higher the degree of recovery; conversely, the smaller the pressure difference between the two pressure sensors 410, the lower the degree of recovery. The controller 500 controls the guidance device to issue instruction signals based on the injured location and degree of recovery to guide the patient in performing single-leg standing training for the injured lower limb, thereby strengthening the injured lower limb and improving the patient's balance. As an example, the guidance device is implemented as a voice broadcaster, and the guidance signal is a voice broadcast.

[0041] The present invention also provides a method for operating the rehabilitation bed, comprising the following steps: (S1) The patient stands on the foot railing 120 of the rehabilitation bed so that the pressure sensor 410 detects the pressure exerted by the patient’s two lower limbs on the foot railing 120 respectively.

[0042] Specifically, the drive mechanism 300 drives the bed body 100 to rotate to any angle in a direction away from the support surface 2001, so that the patient's two lower limbs stand on the foot railing 120. The two pressure sensors 410 respectively detect the pressure exerted by the patient's two lower limbs on the foot railing 120, thereby understanding the degree of injury of the patient.

[0043] (S2) Determine the range of training angles between the support surface 2001 formed by the bed body 110 and the support seat 200 during training, based on the severity of the patient's injury.

[0044] (S3) According to the training angle range, the controller 500 controls the drive mechanism 300 to start at intervals during the training process, so as to gradually increase the angle between the bed body 110 and the support surface 2001 formed by the support seat 200.

[0045] In step (S4) prior to step (S1), the weight sensor 600 measures the patient's weight so that the controller 500 can determine the degree of injury based on the patient's weight.

[0046] In step (S3), the controller 500 controls the drive mechanism 300 to drive the bed body 100 to swing within a preset range relative to the support surface 2001 formed by the support seat 200, based on the pressure sensor 410 monitoring the pressure applied by the two lower limbs to the foot rail 120 in real time.

[0047] Specifically, (S3.1) during the training process, when the data measured by the two pressure sensors 410 fluctuate significantly, the controller 500 controls the drive mechanism 300 to drive the bed body 100 to rotate toward the support surface 2001.

[0048] (S3.2) After a preset rest period, the controller 500 controls the drive mechanism 300 to rotate the bed body 100 away from the support surface 2001 to resume training.
