As shown in Figures 1-9, this embodiment provides a rehabilitation nursing bed, including a bed body 20, left and right bed tops 10, and a rehabilitation combined support 30. The bed body is composed of four bed body segments, starting from the bedside To the direction of the foot of the bed, there are the first bed body section 210, the second bed body section 220, the third bed body section 230, and the fourth bed body section 240; The hinged form is connected to each other. The hinged form of the device adopts the connection form of the shaft and the pin hole hanging lug, so that the adjacent two sections can be adjusted according to the required angle according to the axis and the pin hole as the center of the circle. The second bed section A central shaft 223 that can withstand higher strength and an upper and lower sliding platform 115 connected to both ends of the central shaft are placed horizontally near the third bed section. The guide rails 111 are vertically arranged on the mainboards of the left and right sides of the bed. ; At the same time, the bottom of the main board 110 of the two beds is connected by the pulling support assembly 119, and the bed is installed on the bed head and the foot of the bed respectively with a head guard 211 and a bed foot guard 241 that are perpendicular to the bed;

In this device, the connecting shaft 213 of the pin hole hanging lugs between the first bed body section and the second bed body section is rigidly connected with the first bed body section, and the pin hole hanging lugs between the second bed body section and the third bed body section are connected The shaft 233 is rigidly connected with the third bed section, and the connecting shaft 243 of the pin hole hanging lug between the third bed section and the fourth bed section is rigidly connected with the fourth bed section,

The central axis is rigidly connected with the second bed section. Since the central axis is at the central position of the overall bed, the entire bed can be moved by moving the central axis. In addition to bearing the weight of the overall bed, the central axis also bears the weight of the human body. In addition, the main task of the central axis is to be responsible for the overall bed rotation according to the required angle and the required high and low positions to slide up and down in a straight line;

The length of each bed body is different. According to the human physiological structure and the posture of life activities, the length of each segment is determined: the first bed body segment corresponds to the human body from the top to the shoulder, the second bed body segment corresponds to the human body from the shoulder to the coccyx, and the third bed body segment corresponds to the human body from the shoulder to the coccyx. Corresponding to the human body from the coccyx to the knee, and the fourth bed section corresponds to the human body from the knee to the sole of the foot. The length of each section is directly derived from the height of the user's body. According to different heights, a reference table of height and length of each section of the bed is provided. See below.

Note: The first bed body and the fourth bed body in the table have added 10cm for the activity space on the top of the head and the bottom of the feet.

In this embodiment, a set of vertically arranged linear sliding guide rails 111 are installed on the outer surfaces of the left and right side bed mainboards that are symmetrical to each other, and a rack is installed at a parallel distance from the linear sliding guide rails. 116-2, an elongated through hole with the same length as the linear sliding guide rail and the rack is opened between the linear sliding guide rail and the rack, and the elongated through hole is used for the central axis to pass through the left and right bed tops , and make the two ends of the central shaft be supported on the upper and lower sliding platforms 115 of the linear sliding guides on both sides respectively, and the long through hole for the same purpose also needs to pass through an indispensable, so that the left and right beds can always be kept horizontal. The double-ended gear shaft 117 with mechanical synchronization and self-locking function, in addition to the gear 116-1 with the same module and the same number of teeth, both ends of the double-ended gear shaft 117 also need to be connected with a seated bearing 118 of the same specification. , the bearing with seat is respectively fixed under the bottom plate of the upper and lower sliding platforms 115 of the linear sliding guides on both sides, and the gears 116-1 at both ends thereof are respectively meshed with the racks 116-2 synchronously. After the above-mentioned device is completed, it can be realized: first, once the gears and racks at both ends of the double-ended gear shaft are positioned and meshed, the linear up and down sliding platform on the active side and the linear up and down sliding platform on the passive side have been linked together, and the master-slave two The sides are integrated and on the same horizontal plane. The positioning and meshing means that when the gear rack is engaged and fixed, it must be noted that the horizontal planes of the left and right sides of the straight up and down sliding platform are consistent before positioning and fixing. Second, once the left and right sides of the straight up and down sliding platform are positioned and engaged, the self-locking of the driven side will also obtain the same self-locking with the self-locking of the active side.

In this embodiment, the four bed sections are independently driven by five motors, specifically: the motor numbered No. 1 and the worm gear reducer 112 are installed on one of the left and right linear sliding guides. At the bottom end, the linear lifting sliding guide with the motor numbered No. 1 and the worm gear reducer installed is the active side, and the other side is the driven side. The linear sliding guide on the active side is the existing screw nut lifting mechanism, the screw nut lifting The mechanism adopts the mechanism of screw 113-1 and nut 113-2. The motor numbered as No. 1 and the worm gear reducer are used to drive the screw to drive the nut and then drive the upper and lower sliding platforms to slide up and down, and then driven by the synchronous operation of the double-headed gear shaft. The overall bed slides up and down as a whole, and the linear sliding guide on the driven side is only the ordinary cylindrical slide 114. The upper and lower sliding platforms are directly driven by the double-headed gear shaft. The motor No. 2 and the worm gear reducer 222 are installed. On the up and down sliding platform on either side of the linear lifting sliding guide, it is used to drive either end of the central axis to rotate, and then drive the second bed section to radiate the whole bed through the central axis to adjust the angle rotation. The motor numbered No. 3 and the worm gear decelerate The machine 212 is installed on the frame of the second bed section, and its output end is aligned with the axis line of the rotating connecting shaft 213 in the first bed section and connected with it, and is used to drive the first bed section to rotate relative to the second bed section. Angle adjustment, the motor numbered No. 4 and the worm gear reducer 232 are installed on the frame of the second bed section, and its output end is aligned with the axis line of the rotating connecting shaft 233 in the third bed section and connected with it, for Drive the third bed section to adjust the angle relative to the second bed section. The motor numbered as No. 5 and the worm gear reducer 242 are installed on the frame of the third bed section, and its output end is aligned with the rotating connecting shaft 243 in the fourth bed section. It is used to drive the fourth bed section to adjust the angle relative to the third bed section. The adjustment method is the same as the angle adjustment method between the first bed section and the second bed section. Each section of the bed can have a free angle of independent electric adjustment, and the combination can complete the relative angle required by each section of the bed to achieve the purpose of use.

The specific movement method of the central axis in this embodiment is as follows: the motor numbered No. 1 and the worm gear reducer drive the screw on the active side to rotate, and then drive the nut to slide up and down, and then drive the up and down sliding platform to slide up and down, while the central axis The two ends extend through the long through holes and extend out of the left and right bed help, one end of which is connected with the No. 2 motor and the worm gear reducer, and is supported and fixed on the upper and lower sliding platforms of the linear sliding guide rails at either end, and the other end of the central shaft is installed with a seat bearing. It is fixed on the upper and lower sliding platforms of the linear sliding guides at the other end. Of course, anyone with a mechanical foundation knows that the installation requirements must be that the centerline at both ends of the central axis is at the same height from the surface of the lifting platform at both ends, and the lifting platforms at both ends are at the same height. After the racks and pinions at both ends are meshed and kept horizontal, the central axis must be horizontal. The above device not only realizes the up and down sliding of the central axis, but also realizes the angular rotation of the central axis, and also realizes the permanent level of the central axis, ensuring the bed. Always keep the left and right horizontal state, which is reliable and safe. It is required that both ends of the double-ended gear shaft must be installed with one bearing with the same specification, and one gear with the same module and the same number of teeth. It is installed at the outer end of the shaft, and the housed bearing is installed at the inner position of the gear.

In this embodiment, the horizontal self-locking comes from three aspects: 1. The worm gear reducer of the linear sliding guide on the active side is selected to have self-locking ability; 2. The screw and nut of the linear sliding guide on the active side have self-locking ability; 3. Because The active side has the self-locking ability of the above double insurance, so the device further adopts the rack-and-pinion linkage method of the double-ended gear shaft, which essentially transfers the self-locking of the passive side to the active side through the meshing of the rack and pinion. The self-locking of the side makes the passive side self-locking.

In this embodiment, the combination support for rehabilitation. Figures 2 and 9 are installed on the combined support above the double-arm position at the head of the bed. Two left and right arm tensioners 320 with adjustable tension are installed, which are used for lying down rehabilitation. When nursing the bed, the arm is used for active tension exercise. The adjustable tension is a common tension device that adjusts the number of tension springs in the tension device tube or adjusts the tension of each tension spring to achieve the required tension; the rehabilitation combination bracket is located on the bed.

The upright posture is shown in Figure 1 for details. The upright posture is designed to solve two major problems:

First, in order to solve the problem of getting into and out of bed for patients, especially for patients who cannot take care of themselves, it is very difficult to get in and out of bed. It is common for two or three people to help the patient to go to bed or get out of bed, so the upright type is designed. The body position is much more convenient. For example, when going to bed, set the bed to an upright position. The patient takes a step back with his back to the bed, his feet are on the foot guards of the bed, and his back is close to the bed. Next, first set it in the armpit. The lower armpit safety bars located on the left and right sides of the chest are pulled close to both sides of the chest (the device can be pulled horizontally), and the arms are clamped and the hands are grasped on the safety bars. Depending on the patient's self-awareness, if necessary For extra safety, the body and the safety bar can also be tied together with a rope strap. You can touch the flat-lying position on the touch screen, the bed starts to change from the upright position, and the bed is turned back 90 degrees to become the flat-lying position. It is also convenient to go to bed. Do the reverse operation of the same sequence to complete the so-called step forward, then step on the ground and get out of bed.

Second, in order to achieve (pulling, spreading) with the bed, that is, to achieve toilet sitting with the bed, the upright posture is a necessary posture for the preparations before and after the toilet. The preparations that need to be completed in the upright posture before the toilet are : 1. Loosen clothes and trousers, 2. Take off the mattress above the toilet to expose the toilet seat of the toilet, 3. Tie the flexible toilet bag, three tasks have completed the preparatory work, namely The sitting posture can be touched by touching the touch screen, see Figure 3 for details, the bed will start to change position, the human body only needs to be close to the bed with the back, and it will automatically become a sitting posture, sitting on the toilet as the bed changes. The toilet seat can be used to sit with the bed; after the toilet, the bed needs to return to the upright position to complete the three tasks after the toilet: 1. Putting on the clothes, 2. Restoring the removed mattress, 3. Removing the flexible Set the toilet bag to complete the whole process of sitting on the bed.

Further, the standard sitting posture, as shown in Figure 4, is to achieve eating, drinking, working, writing, and watching multimedia videos with the bed. This posture must also be equipped with a desktop board, which can be fixed on the edge of the bed. It can be turned up to form a desktop with a hinge structure, and a desktop board can also be attached when needed, and removed when not in use. Since it is a common matter, it is not shown in Figure 4.

Further, the easy chair posture, see attached drawing 5 for details, is the most popular leisure sitting posture, it reduces the bearing capacity of the waist, distributes the center of gravity of the human body to the back burden, and is most suitable for reading, reading newspapers, drinking straw beverages, And watching multimedia videos, you can feel relaxed and comfortable.

Further, the comfortable curved lying posture, see Figure 6 for details, an informal sleeping posture that people like, a kind of nap, a posture for relaxing browsing, swiping mobile phones and watching multimedia videos, in addition to It can have a custom body position, which can be adjusted at will.

According to the human physiological structure and human life and activity posture, this device designs the transformation of various body positions, and in the transformation process, it is consistent with the human body deformation action, so it will not hurt the patient in bed, and in a real sense, it can follow The purpose of changing the position of the bed.

The device has changed the particularly tiring and tedious hard work of lying on the bed for a long time in the process of treating boils or in the recovery process of patients with difficulty in moving. The quality of speech during illness and recovery is very important. In addition, the present invention is accompanied by rehabilitation equipment, which is of great significance to the quality of the patient's rehabilitation care.
