DETAILED DESCRIPTION

[0028] The utility model is described in detail below with reference to the accompanying drawings.

[0029] As attached Figure 1 and attached Figure 2 As shown, a patient transfer nursing bed of an embodiment of the utility model comprises a bed body 101, a bed board 102 and an adjusting mechanism 200. A through slot running through from top to bottom is provided in the middle of the bed body 101, the bed board 102 is installed in the through slot, and the adjusting mechanism 200 comprises a mounting seat 201, forward and reverse screws 203, a threaded block 204, a connecting rod 205 and a supporting plate 207. A mounting seat 201 is respectively installed on the front and rear sides of the bottom surface of the bed body 101, and the two mounting seats 201 are respectively rotatably connected to one end of the forward and reverse screws 203. A servo motor 202 is installed at either end of the forward and reverse screw rods 203, and the servo motor 202 is used to drive the forward and reverse screw rods 203 to rotate. A thread block 204 is threadedly connected to the forward thread segment and the reverse thread segment of the forward and reverse screw rods 203 respectively, and two connecting rods 205 are hinged on the two thread blocks 204 respectively. The end of the connecting rod 205 on each thread block 204 away from the thread block 204 is hinged to a support plate 207, and the two support plates 207 are detachably connected to the front and rear sides of the bottom surface of the bed board 102 respectively.

[0030] When the device of the utility model is in use, through the detachable connection between the bed body 101 and the bed board 102, the use height of the bed board 102 is adjusted by the adjustment mechanism 200, so that the patient can lie flat on the bed board 102 and the patient and the bed board 102 can be transported as a whole, instead of directly transporting the patient. This can improve the flexibility and safety of patient transportation, and at the same time can reduce the medical staff required for transporting the patient to a certain extent, thereby saving medical resources, and at the same time can improve the comfort of the patient during transportation, avoiding further harm to the patient who cannot move.

[0031] Specifically, when in use, the forward and reverse screws 203 can be driven to rotate by the servo motor 202, and the two threaded blocks 204 on the forward and reverse screws 203 can move back and forth relative to each other or towards each other according to different threads; when the two threaded blocks 204 move towards each other, the bed board 102 can be raised under the action of devices such as the connecting rod 205 and the support plate 207. At this time, the support plate 207 can be separated from the bed board 102 and the bed board 102 can be transported; when the two threaded blocks 204 move relative to each other, the bed board 102 can be lowered under the action of devices such as the connecting rod 205 and the support plate 207, so as to facilitate the next installation with the bed board 102.

[0032] In another embodiment, two rotating grooves are provided inside the two threaded blocks 204, and a connecting rod 205 is rotatably installed in the two rotating grooves of each threaded block 204. The connecting rod 205 is rotatably connected to a rotating seat 206 at one end away from the threaded block 204. The top surfaces of the two rotating seats 206 on the same threaded block 204 are respectively fixedly installed on the left and right sides of a support plate 207, and the top of the support plate 207 is arranged to fit the bottom of the bed board 102. In this way, the stability of the connection between the threaded block 204, the connecting rod 205 and the support plate 207 is ensured.

[0033] In another embodiment, the support plate 207 is detachably connected to the bed plate 102 by bolts 103. Figure 3 As shown, a first threaded hole is formed through the support plate 207, and a second threaded hole is formed correspondingly on the bed board 102, and bolts 103 are threadedly connected in both the first threaded hole and the second threaded hole. In this way, the support plate 207 and the bed board 102 can be easily disassembled and assembled.

[0034] In another embodiment, the mounting seat 201 is symmetrically arranged along the center line in the front-rear direction of the bed body 101. In this way, the use efficiency and stability of the adjustment mechanism 200 are guaranteed.

[0035] As attached Figure 4As shown, in another embodiment, the lower end of the through slot of the bed body 101 is set as a constriction, and the space above the through slot and the constriction is used as a slot for the bed board 102 to be engaged. In this way, the bed board 102 and the bed body 101 are stably connected.

[0036] The depth of the slot is consistent with the thickness of the bed board 102. Thus, the bed board 102 can be placed through the slot, and the height of the bed board 102 and the bed body 101 can be kept consistent, which can avoid discomfort to the patient.

[0037] As attached Figure 5 As shown, in another embodiment, a restraining mechanism 300 is further included, and the restraining mechanism 300 includes a first guide rod 301, a first slider 302, a vertical rod 303 and a restraining member. A horizontally arranged first groove is respectively opened on the left and right sides of the bed body 101, and the first guide rod 301 is respectively fixedly installed in the first groove. A plurality of first sliders 302 are slidably connected to the first guide rod 301, and the first slider 302 can slide back and forth on the first guide rod 301. The first slider 302 is respectively connected to the vertical rod 303, and the vertical rod 303 is respectively connected to the restraining member, and the restraining member is used to bind and restrain the patient. In this embodiment, the first guide rod 301 can facilitate the sliding of the first slider 302, and at the same time, the sliding of the first slider 302 can be guided and limited to prevent the first slider 302 from being slightly deflected during sliding, resulting in sliding obstruction.

[0038] Thus, through the above arrangement, the patient's limbs can be fixed, thereby preventing the patient from shaking under the action of inertia during transportation, preventing the patient's injured part from being more seriously injured, and protecting the patient to a certain extent. At the same time, during use, the first slider 302 can be slidably connected to the first guide rod 301 to meet the needs of adjusting the restraint for patients of different body sizes.

[0039] As attached Figure 6 and attached Figure 7As shown, in the present embodiment, a vertically arranged T-slot is provided on one side of the vertical rod 303 away from the bed body 101, and vertically arranged second grooves are respectively provided in the groove walls on the front and rear sides of the T-slot, and vertically arranged second guide rods 304 are provided in the two second grooves, and second sliders 305 are respectively slidably connected to the two second guide rods 304, and springs 306 are respectively connected between the top surfaces of the second sliders 305 and the top surfaces of the inner sides of the second grooves, and the springs 306 are sleeved on the second guide rods 304, and the two second sliders 305 are fixedly connected by a pressing plate 307, and a T-block 308 is fixedly installed on the bottom of the pressing plate 307, and a plurality of limit grooves for the T-block 308 to be inserted from top to bottom are respectively provided on the left and right sides of the bed body 101, and the springs 306 are used to keep the T-block 308 in a downward movement trend. Therefore, when in use, the T-shaped block 308 can be pressed downward by the spring 306 so that the T-shaped block 308 is firmly fixed in the limiting groove. Thus, when determining the use position of the vertical rod 303 and the restraining member, they are limited and fixed to a certain extent to ensure the stability of use.

[0040] The second guide rod 304 can facilitate the sliding of the second slider 305 and prevent the second slider 305 from being slightly deflected during sliding, which may cause the sliding to be blocked; the second slider 305 can drive the pressure plate 307 to be lifted during the lifting process, and the pressure plate 307 can drive the T-shaped block 308 to be lifted during the lifting process. The second slider 305 can stretch or compress the spring 306 during the lifting process, which can play a buffering role to a certain extent, and can control the T-shaped block 308 to descend into the limiting groove under the action of the spring 306's own elasticity and the T-shaped block 308's own gravity, thereby realizing the positioning of the vertical rod 303.

[0041] Among them, a handle is provided on one side of the T-shaped block 308 away from the bed body 101. In this way, when in use, medical staff can easily push the T-shaped block 308 up or down through the handle, thereby facilitating the release or positioning of the T-shaped block 308 and the positioning groove.

[0042] In this embodiment, the restraining member includes a restraining belt 311 and a restraining ring 310, and the vertical rod 303 and the restraining ring 310 are connected by a telescopic frame 309. Figure 5As shown, there are four vertical rods 303 located on the same side, and one side of two vertical rods 303 is fixedly installed with a telescopic frame 309, and the piston rod end of the telescopic frame 309 is fixedly connected with a restraining ring 310, and one side of two vertical rods 303 is fixedly installed with a restraining belt 311. When in use, medical staff can adjust the restraining ring 310 or the restraining belt 311 as needed. During the movement of the vertical rod 303, the restraining ring 310 and the restraining belt 311 can be driven to move at the same time. When the restraining ring 310 and the restraining belt 311 move to the predetermined position, the patient's limbs can be fixed to prevent the patient from shaking during transportation.

[0043] When the device of the utility model is in use, when the forward and reverse screw rods 203 rotate, the two threaded blocks 204 can be driven to move toward or relative to each other. When the two threaded blocks 204 move toward or relative to each other, the inclination angle of the connecting rod 205 will change. When the two threaded blocks 204 move toward each other, the inclination angle of the connecting rod 205 will increase. When the two threaded blocks 204 move relative to each other, the inclination angle of the connecting rod 205 will decrease. When the threaded block 204 drives the inclination angle of the connecting rod 205 to change, it can drive the end of the connecting rod 205 away from the threaded block 204 to rotate inside the rotating seat 206, so that the height of the support plate 207 can be adjusted. When the inclination angle of the connecting rod 205 increases, the height of the support plate 207 increases. When the inclination angle of the connecting rod 205 decreases, the height of the support plate 207 decreases.

[0044] When the patient needs to be moved, the bolt 103 is removed to control the support plate 207 to separate from the bed board 102, and then the bed board 102 can be moved. After the patient is moved to another bed body 101, it is only necessary to align the second threaded hole at the bottom of the bed board 102 with the first threaded hole on the support plate 207, and then connect the bed board 102 and the support plate 207 through the bolt 103.

[0045] The utility model can realize the patient lying flat on the bed board 102 for transportation by means of the mutual cooperation of the components in the adjustment mechanism 200, instead of directly transporting the patient, which can improve the flexibility of patient transportation and reduce the number of medical staff for transporting the patient to a certain extent, thereby saving medical resources and improving the comfort of the patient during transportation;

[0046] Through the cooperation of the various components in the restraint mechanism 300, the patient's limbs can be fixed, thereby preventing the patient from shaking due to inertia during transportation, preventing the patient's injured parts from being more seriously injured, and protecting the patient to a certain extent.
