[0053] Example

[0054] This embodiment aims to address the shortcomings of existing restraint devices, which are mostly fixed hospital beds that only support supine restraint and cannot accommodate patients requiring sitting, semi-reclining, or other special positions. Referring to the figures, this embodiment provides an emergency critical care position restraint transport device. It utilizes a multi-segment support platform 4 to adapt to various position restraint requirements, including supine and sitting postures; a rotating platform and wheels 11 for flexible transport; and adjustable restraint components 45 for segmented patient immobilization, effectively restraining the patient's limbs and preventing accidental injury or interference with treatment.

[0055] An emergency critical care positioning and transport device includes a base 1, a rotating platform 2, a rotation drive mechanism 3, a multi-segment support platform 4, a power supply 5, and a control panel 6.

[0056] The base 1 has multiple wheels 11 at its bottom, which are used for the overall movement of the device. The base 1 can be a hollow shell to house the various components. Four wheels 11 can be used, with the two at the front configured as omnidirectional wheels to facilitate directional adjustment when the user moves the entire device. In some embodiments, the omnidirectional wheels can be configured as existing casters with locking functions.

[0057] The rotating platform 2 is rotatably mounted on the top surface of the base 1. The rotating platform 2 can be a circular plate.

[0058] The rotary drive mechanism 3 located in the base 1 includes a rotating shaft 31 extending out of the base 1, one end of which is connected to the axis of the rotating platform 2; the rotary drive mechanism 3 can drive the rotating platform 2 to rotate through the rotating shaft 31.

[0059] A multi-segment support platform 4 is located on top of the rotating platform 2. It includes a main support component 41 fixed to the multi-segment support platform 4, and a left support component 43 and a right support component 44 connected to the two sides of the main support component 41 via a hinge mechanism 42. The main support component 41, the left support component 43, and the right support component 44 are each provided with an adjustable restraint component 45, which is used to fix the patient's position. A drive unit 46 is provided on both sides of the bottom of the main support component 41, and the drive unit 46 is rotatably connected to the left support component 43 and the right support component 44.

[0060] The rotary drive mechanism 3 can drive the multi-segment support platform 4 to rotate as a whole to adjust the transfer direction. The drive unit 46 can drive the left support component 43 and the right support component 44 to rotate around the hinge mechanism 42 so that the multi-segment support platform 4 can switch between the horizontal bed form and the tilted chair form.

[0061] The power supply 5, the rotary drive mechanism 3, and the drive unit 46, which are located in the base 1, are electrically connected to the power supply 5.

[0062] Control panel 6 is electrically connected to power supply 5, rotary drive mechanism 3, and drive unit 46. Control panel 6 is located at the end of the left support component 43 and includes a main control chip and a touchscreen, with touch-sensitive buttons for rotation control.

[0063] The main support component 41 includes: a connecting plate 411, a support frame 412, and a main support plate 413. The connecting plate 411 is detachably connected to the rotating platform 2; specifically, the connecting plate 411 and the rotating platform 2 are fixed together by multiple bolts.

[0064] A support frame 412 is positioned on top of the connecting plate 411; a main support plate 413 is positioned on top of the support frame 412 and is used to support the patient's buttocks; handles 431 are respectively provided on both sides of the end of the left support member 43, and foot pedals 441 are respectively provided on both sides of the end of the right support member 44. The left support member 43 corresponds to the patient's upper body, and the right support member 44 corresponds to the patient's legs.

[0065] The emergency critical care positioning and transport device also includes a lifting drive assembly 7 disposed within the base 1 for adjusting the support height of the multi-segment support platform 4. This assembly includes at least two electric drive units 71. The output ends of the electric drive units 71 extend beyond the top surface of the base 1. The bottom of the rotating platform 2 is symmetrically equipped with the output ends of at least two electric drive units 71, which are capable of driving the rotating platform 2 to rise and fall relative to the base 1. The control panel 6 has touch-sensitive buttons for lifting control. The electric drive units 71 can be electric cylinders.

[0066] The rotary drive mechanism 3 also includes a drive motor 32 and a rotating bushing 33. The drive motor 32 can be an existing servo motor.

[0067] The drive motor 32 is detachably installed inside the base 1, and its output shaft is equipped with a drive gear 321. The rotating bushing 33 is rotatably connected to the base 1 through a bearing seat; the inner wall of the rotating bushing 33 is provided with a guide groove along the axial direction; the outer side of the rotating bushing 33 is equipped with a driven gear 331 that meshes with the drive gear 321.

[0068] The outer circumference of the rotating shaft 31 is provided with a protrusion 311 that matches the guide rail groove. When the rotating shaft 31 is inserted into the rotating bushing 33, the protrusion 311 is engaged with the guide rail groove. The protrusion 311 can slide along the guide rail groove, and the rotating shaft 31 and the rotating bushing 33 rotate coaxially. It should be noted that the protrusion 311 can slide up and down along the guide rail groove, allowing the rotating shaft 31 to move vertically within the bushing. Its stroke is consistent with the stroke of the lifting drive assembly 7. The rotating shaft 31 and the bushing achieve coaxial rotation through the cooperation of the protrusion 311 and the groove, ensuring that the rotating shaft 31 rotates synchronously with the bushing.

[0069] During the platform rising phase: the lifting drive assembly 7 pushes the lifting plate 72 and the rotating platform 2 to move upward. The rotating shaft 31 is subjected to the lifting force of the platform, and its protrusion 311 slides upward along the guide groove of the bushing. Only axial relative movement occurs between the rotating shaft 31 and the bushing, and the two remain coaxial to avoid skew and jamming. Rotation is prohibited during the rising phase.

[0070] During the platform descent phase: the electric cylinder of the lifting drive assembly 7 retracts, the lifting plate 72 drives the rotating platform 2 to descend, and the protrusion 311 of the rotating shaft 31 slides down along the guide rail groove until it returns to its initial position.

[0071] The drive motor 32 meshes with the driven gear 331 on the outside of the bushing via the drive gear 321, driving the bushing to rotate. Since the rotating shaft 31 and the bushing rotate synchronously with rigidity through the guide groove, torque is transmitted through the protrusion 311, driving the rotating platform 2 to rotate.

[0072] The rotating platform 2 includes a rotating plate 21 and at least three load-bearing wheels 22.

[0073] The rotating plate 21 is fixedly connected to the rotating shaft 31 at the bottom center; at least three bearing wheels 22 are evenly distributed on the top surface of the base 1, and the bottom of the rotating plate 21 can be slidably connected to the at least three bearing wheels 22.

[0074] The hinge mechanism 42 is a damping pivot component, including a left movable shaft 421 and a right movable shaft 422. The left support component 43 and the right support component 44 form an adjustable angle of 90° to 180° with the main support component 41 in the tilt chair configuration.

[0075] The adjustable restraint assembly 45 includes an elastic restraint strap 451, which includes a first strap 45a disposed on one side of the multi-segment support platform 4 and a second strap 45b disposed on the other side of the multi-segment support platform 4; the first strap 45a and the second strap 45b are connected by Velcro to form a restraint state.

[0076] The drive unit 46 is an electric push rod, which is rotatably connected to the main support component 41; the output end of the electric push rod is rotatably connected to the left support component 43 or the right support component 44.

[0077] The right support component 44 includes: a support plate 445, a first rod 442, and a second rod 443. The first rod 442 and the second rod 443 are respectively connected to both sides of the support plate 445; the ends of the first rod 442 and the second rod 443 extend out of the support plate 445, and the ends of the first rod 442 and the second rod 443 are provided with bent portions 444; foot pedals 441 are respectively provided on the inner side of the bent portions 444.

[0078] The lifting drive assembly 7 also includes a lifting plate 72. The lifting plate 72 is mounted on the output ends of at least two electric drive units 71, and the lifting plate 72 is parallel to the lifting platform.

[0079] It should be added that the multi-segment support platform 4 can be rotated and adjusted: when it is necessary to adjust the patient's orientation (such as when entering or exiting an elevator or a small space), the control panel 6 sends a command to the rotation drive mechanism 3. The servo motor drives the driven gear 331 through the active gear 321, which drives the rotating shaft 31 and the rotating platform 2 to rotate, so that the multi-segment support platform 4 is rotated as a whole to the target direction, reducing the number of times the device is moved repeatedly.

[0080] It should be added that the form switching of the multi-segment support platform 4 is as follows:

[0081] Flat bed morphology:

[0082] The left and right support components 44 are folded together by the hinge mechanism 42 to be horizontally aligned with the main support component 41, forming a flat transfer bed surface, which is suitable for comatose or critically ill patients who need to lie flat.

[0083] Inclined chair form:

[0084] Drive unit 46 action: Control panel 6 triggers electric push rod, push rod retracts and drives left / right support component 44 to rise around hinge mechanism 42, forming a specified angle with main support component 41, switching to semi-sitting or sitting position to adapt to the needs of patients with breathing difficulties or who are awake.

[0085] Lifting and coordinated control: Height adjustment, the electric drive component 71 drives the lifting plate component 72 to lift vertically, adjust the platform height to adapt to different transport tools (such as ambulance stretchers, operating tables).

[0086] The electronic devices provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
