[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0026] like Figures 1 to 4 As shown, a preferred embodiment of the present invention provides a medical transport bed, which has mutually perpendicular X, Y and Z directions, including a base frame 1, a bed frame 6 and a bed board 8;
[0027] The base frame 1 has a moving component 2 at its bottom and a lifting component 3 at its top;
[0028] The support frame 4 is fixedly connected to the top of the lifting assembly 3. The lifting assembly 3 is used to drive the support frame 4 to move relative to the base frame 1 in the Z direction. The support frame 4 is provided with an tilting assembly 5.
[0029] The bed frame 6 is movably connected to the tilting component 5 and the support frame 4. The tilting component 5 is used to drive the bed frame 6 to rotate and tilt relative to the support frame 4 about a rotation axis parallel to the Y direction. The bed frame 6 is provided with a translation component 7.
[0030] The bed board 8 is connected to the translation assembly 7, which is used to drive the bed board 8 to move relative to the bed frame 6 in the X direction; the bed board 8 is provided with a transport assembly 9, which is used to adjust the position of the patient relative to the bed board 8.
[0031] Among them, the Y direction is parallel to the long side of the bed board 8, and the Z direction is perpendicular to the surface of the bed board 8.
[0032] Specifically, in hospitals, some patients with limited mobility often need to be transferred using medical transport beds. Traditional medical transport beds only have simple raising and lowering functions to keep the height of the medical transport bed level with the hospital bed. Afterwards, medical staff still need to work together to move the patient onto the medical transport bed, which is not only inefficient and time-consuming, but also easy to cause secondary injury to the patient due to exhaustion or slipping. In this application, the lifting component 3 is used to raise or lower the overall height of the support frame 4, bed frame 6, and bed board 8, so that the height of the bed board 8 is level with the hospital bed, facilitating subsequent transfer work. When it is necessary to transfer the patient from the bed board 8 to the hospital bed, the tilting component 5 can be activated to raise the side of the bed board 8 away from the hospital bed. With the bed board 8 tilted, the patient can be moved from the transfer bed to the hospital bed more easily and effortlessly under the action of gravity, avoiding the trouble of medical staff working together to move the patient, and improving the efficiency and safety of patient transfer. When it is necessary to transfer the patient from the hospital bed to the medical transport bed, the translation component 7 can be activated to move the bed board 8 to the side of the patient's body on the hospital bed. Then, the transport component 9 can be activated to adjust the position of the patient relative to the bed board 8, so that the patient can move to the middle of the bed board 8. Finally, the translation component 7 moves the bed board 8 and the patient on it to the top of the bed frame 6, and then moves it to other positions through the moving component 2. In this embodiment, the transfer of patients between the medical transport bed and the hospital bed eliminates the trouble and risk of medical staff having to lift and transfer patients together, improving the efficiency and safety of patient transfer, and making the entire transfer process more convenient and labor-saving.
[0033] In some embodiments, the lifting assembly 3 includes a plurality of first push rods 31 symmetrically arranged on both sides of the base frame 1 along the Y direction, and the support frame 4 is provided with a first lifting plate 32 corresponding to the first push rods 31, with the output end of the first push rod 31 abutting against the first lifting plate 32.
[0034] Furthermore, one first push rod 31 is provided at each of the four corners of the top surface of the base frame 1; an auxiliary lead screw 33 is also provided between the two first push rods 31 symmetrically along the X direction, and a second lifting plate 34 is provided on the support frame 4 corresponding to the auxiliary lead screw 33.
[0035] Specifically, when transferring a patient, the height of the bed board 8 needs to be adjusted first so that the top surface of the bed board 8 is not higher than the height of the bed, thus facilitating the transfer of the patient. The first push rod 31 can simultaneously lift the support frame 4 on both sides along the Y direction, thereby smoothly raising the height of the bed frame 6 and the bed board 8 on the support frame 4. The auxiliary screw 33 can simultaneously lift the second lifting plate 34 when the first push rod 31 lifts the first lifting plate 32, further improving the stability of the support frame 4 when the first push rod 31 lifts it, thus ensuring the stability of the bed board 8 during the patient transfer process and improving the stability and safety of the patient transfer.
[0036] In other embodiments, the first lifting plate 32 has a through hole 321 in the middle, and the output end of the first push rod 31 is connected to a limiting rod 311, which is sleeved in the through hole 321. The top surface of the base frame 1 is rotatably connected to a plurality of auxiliary rods 35, and the other end of the auxiliary rods 35 is rotatably connected to the support frame 4. The axes of relative rotation of the two ends of the auxiliary rods 35 are parallel to the X direction. Specifically, during the normal lifting of the support frame 4, the output ends of the first push rods 31 on both sides of the base frame 1 will simultaneously abut against the first lifting plate 32 on the support frame 4 to lift the support frame 4. When it is necessary to control the bed board 8 to be in an inclined state with the head higher than the feet, the first push rods 31 on both sides of the base frame 1 along the Y direction can be controlled to lift the support frame 4 at different speeds, thereby achieving the state of the support frame 4 with the head higher than the feet or the head lower than the feet. The setting of the limiting rod 311 and the through hole 321 can limit the relative position between the first lifting plate 32 and the first push rod 31, preventing the first push rod 31 from deviating too much from the first lifting plate 32 during the tilting process, and also preventing the support frame 4 from completely deviating from the base frame 1 and slipping off the base frame 1. The setting of the auxiliary rod 35 is also to assist the tilting of the support frame 4 and provide stable support and connection for the tilting of the support frame 4 relative to the base plate.
[0037] In some embodiments, the tilting component 5 includes a second push rod 51 fixedly mounted on the support frame 4. The output end of the second push rod 51 is rotatably connected to the bed frame 6. The output end of the second push rod 51 is tilted upward relative to the support frame 4 in the X direction to lift one side of the bed frame 6 so that the bed frame 6 can rotate and tilt.
[0038] Furthermore, two second push rods 51 are symmetrically arranged on the support frame 4 along the Y direction; the side of the bed frame 6 away from the second push rod is rotatably connected to the support frame 4.
[0039] Specifically, there are two states when transferring patients: one is transferring the patient from the hospital bed to the medical transport bed, and the other is transferring the patient from the medical transport bed to the hospital bed. In the latter process, existing technology generally requires medical staff to work together to move the patient, which is very inconvenient and poses safety hazards. In this embodiment, when it is necessary to move the patient from the medical transport bed to the hospital bed, it is only necessary to first adjust the height of the medical transport bed to be level with the hospital bed, then move the medical transport bed close to the hospital bed, and then control the second push rod 51 to start pushing the side of the bed frame 6 away from the hospital bed to raise it, so that the bed rotates around the point where it is connected to the support frame 4, creating a tilted state of the bed frame 6. Then, under the action of gravity, the patient can be moved from the transport bed board 8 to the hospital bed more conveniently and effortlessly. The entire transfer process reduces the involvement of medical staff, which not only makes the transfer more efficient and less strenuous, but also improves safety.
[0040] In some embodiments, a translation component 7 is provided on each side of the bed frame 6 along the Y direction. The translation component 7 includes a slide rail 71 and a third push rod 72. The slide rail 71 extends along the X direction, and the third push rod 72 is used to drive the bed board 8 to slide along the slide rail 71.
[0041] Furthermore, the conveying assembly 9 includes a conveyor belt 91 and a drive unit 92. The conveyor belt 91 is sleeved on the bed plate 8, and the drive unit 92 is fixed on both sides of the bed plate 8 along the Y direction. The drive unit 92 is used to drive the conveyor belt 91 to move and rotate along the X direction.
[0042] Specifically, in this embodiment, when a patient needs to be transferred from a hospital bed to a medical transport bed, the height of the support frame 4, bed frame 6, and bed board 8 is first lowered by the first push rod 31 so that the height of the bed board 8 is level with the hospital bed. Then, the third push rod 72 pushes the bed board 8 to move along the slide rail 71 away from the bed frame 6 until the bed board 8 is below the patient's body on the hospital bed. Subsequently, the drive unit 92 drives the conveyor belt 91 to rotate, and the conveyor belt 91 moves the patient towards the middle of the bed board 8. After the patient moves to the middle of the bed board 8, the third push rod 72 drives the bed board 8 to move along the X direction towards the bed frame 6 until the bed board 8 and the patient on it are directly above the bed frame 6. This completes the entire process of transferring the patient from the hospital bed to the medical transport bed. The patient transfer is more efficient, more convenient and less strenuous, and safer.
[0043] In some embodiments, the base frame 1 is equipped with a controller 11, which controls the operating status of the lifting assembly 3, tilting assembly 5, translation assembly 7, and transport assembly 9. Specifically, the controller 11 controls the working status of the first push rod 31, the second push rod 51, the third push rod 72, and the drive component 92, thereby regulating the overall working status of the medical transport bed and enabling it to meet more usage needs. Correspondingly, the medical transport bed is also equipped with various supporting sensors for monitoring and feedback of its status, so as to facilitate the control by the controller 11. In addition, the controller 11 is also integrated with a wireless receiver, which can receive wireless signals. Medical personnel can send signals to the controller 11 through a portable control terminal, thereby controlling the working status of the medical transport bed.
[0044] In some embodiments, the moving component 2 includes self-locking casters 21 located at the four corners of the base frame 1. The self-locking casters 21 enable easier and more convenient movement of the medical transport bed, thereby facilitating the movement of patients.
[0045] In summary, this utility model embodiment provides a medical transport bed, which adjusts the height of the bed board 8 using a first push rod 31 to adapt to beds of different heights. Then, the second push rod 51 pushes the bed board 8 to tilt, making it easier and less strenuous for patients to transfer from the medical transport bed to the hospital bed. When it is necessary to transfer a patient from the hospital bed to the medical transport bed, the third push rod 72, in conjunction with the conveyor belt 91 and the drive unit 92, can change the patient's position. Since the entire process of transporting and transferring patients is carried out automatically, the process of medical staff working together to move patients is eliminated, making patient transfer not only more time-saving and labor-saving, but also safer.
[0046] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
