Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. It should be pointed out that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size, and any size is only exemplary and not restrictive.

[0039] Embodiment 1:

[0040] See also Figure 1 - Figure 7 As shown, a patient transport frame for critical care and a manufacturing method thereof include a transport frame body 1, the transport frame body 1 includes a bed frame 11, a bottom frame 14, a bed head 12 fixedly connected to the bed frame 11, a support rod 13 fixedly connected to the bottom of the bed frame 11, a universal wheel 15 rotatably connected to the bottom frame 14, a bottom plate 16 fixedly connected to the bottom frame 14, and a guardrail 17 is arranged on one side of the bed frame 11. The bed frame 11 and the bottom frame 14 are the main structures of the transport frame body 1, which are made of high-strength and lightweight materials to ensure stability and durability. The bed head 12 is composed of stainless steel and latex pads to provide support for the patient's head, and the latex pads increase the patient's comfort. The support rod 13 is a retractable arrangement to provide support for the bed frame 11, the universal wheel 15 allows the whole to rotate flexibly in multiple directions, so as to facilitate the movement of patients in a small or crowded space. The bottom plate 16 is used to receive the support rod 13, and the guardrail 17 is used to prevent the patient from accidentally falling from the transport frame when sleeping or moving, so as to protect the patient's safety.

[0041] The sliding assembly 2 includes a bed board 21 arranged on the bed frame 11, and a limit rod 26 is rotatably connected to the bed head 12. The sliding assembly 2 is used to smoothly and slowly transfer the patient.

It is used to bear the weight of the patient. The limit rod 26 is used to limit the bed board 21.

[0042] The adjusting assembly 3 includes a lever 33 rotatably connected to the inner side of the bottom frame 14, and a triangular plate 36 is fixedly connected to the bottom of the bed frame 11. The adjusting assembly 3 is used to adjust the overall height so that the transfer frame can easily adapt to the height of different medical equipment. The lever 33 is used to provide support for the triangular plate 36, and the triangular plate 36 is used to establish a connection between the bed frame 11 and the lever 33;

[0043] The locking assembly 4 includes a rotating plate 44 arranged in the universal wheel 15, and an arc rod 45 is rotatably connected to the rotating plate 44. The locking assembly 4 is used to prevent the transfer frame from continuing to move when it is about to slide accidentally. The rotating plate 44 is used to receive the arc rod 45. The arc rod 45 fits tightly against the inner wall of the universal wheel 15 to increase the friction force, thereby achieving the locking of the wheel 152.

[0044] Specifically, the universal wheel 15 includes an axle frame 151 and a wheel 152 rotatably connected to the axle frame 151. The axle frame 151 is used to receive the wheel 152, and the wheel 152 drives the whole to move.

[0045] Furthermore, there are two bedside heads 12 and guardrails 17, which are symmetrically arranged to protect patients and prevent them from falling out due to emergency braking of the transfer frame. The bottom of the support rod 13 is slidably connected to the base plate 16. As the height of the bed frame 11 is adjusted, the support rod 13 will slide on the base plate 16. There are multiple axle frames 151 and wheels 152, which are symmetrically arranged and are respectively arranged at the four corners of the bottom frame 14, so that the transfer frame maintains stability during transportation.

[0046] Furthermore, a cone block 211 is fixedly connected to the bottom of the bed board 21, a tooth groove 212 is provided at the end of the bed board 21, a rocker 22 is rotatably connected to the bed frame 11, a gear 23 is fixedly connected to the end of the rocker 22, a conical groove 24 is provided on the bed frame 11, a notch 25 is provided on the bed frame 11, the conical groove 24 is used to receive the cone block 211, the tooth groove 212 is used to receive the gear 23, the rocker 22 is used to provide driving force for the gear 23, the gear 23 is used to drive the bed board 21 to move, and the cone block 211 can be disengaged from the conical groove 24 through the notch 25.

[0047] Furthermore, the cone block 211 is slidably connected in the cone groove 24, the size of the cone block 211 is adapted to the size of the opening of the cone groove 24, the cone block 211 is guided by the cone groove 24, drives the bed plate 21 to move, the gear 23 engages in the tooth groove 212, there are two cone grooves 24 and they are symmetrically arranged, there are multiple cone blocks 211 and notches 25 and they are symmetrically arranged, and the number of cone blocks 211 corresponds to the number of notches 25.

[0048] As can be seen from the above, when the patient needs to be transferred, the rocker 22 is shaken, the rocker 22 rotates on the bed frame 11, and the rocker 22 drives the gear 23 fixedly connected at its end to rotate. Because the gear 23 is engaged in the tooth groove 212 opened on the bed board 21, the bed board 21 drives the cone block 211 to move rightward in the cone groove 24, and is limited by the cone groove 24 to prevent deviation until the bed board 21 is close to the patient. At this time, the patient is transferred to the bed board 21. Conversely to the above, the rocker 22 is reversed, the bed board 21 drags the patient to reset, and is limited by the limit rod 26, so that the patient is transferred to the transfer frame. The bed board 21 is moved smoothly and slowly. The risk of patient movement is reduced, the safety of patients during transportation is ensured, and medical staff can easily transfer patients from beds, wheelchairs or other medical equipment to the transport frame without the need to lift or drag patients laboriously, thereby improving the efficiency of transportation. When the transport frame is not transporting patients and is idle, the limit rod 26 is rotated to cancel the limit on the bed board 21 by the limit rod 26, and the rocker 22 is reversed to move the bed board 21 to the left. When it moves to the end, the multiple cone blocks 211 fixedly connected to the bed board 21 are aligned with the multiple slots 25 opened on the bed frame 11. At this time, the bed board 21 can be disassembled, which is easy for medical staff to clean and maintain it.

[0049] Embodiment 2:

[0050] See also Figure 5 As shown, this embodiment is basically the same as the previous embodiment, with the difference that a fixing plate 31 is fixedly connected to the side of the bottom frame 14, a motor 32 is fixedly connected to the fixing plate 31, a fixing rod 34 is fixedly connected to the lever 33, a conveyor belt 35 is sleeved on the end of the fixing rod 34, the fixing plate 31 is used to receive the motor 32, the motor 32 is used to provide driving force for the fixing rod 34, the fixing rod 34 is used to connect the two levers 33, and both ends of the conveyor belt 35 are sleeved on the ends of the two fixing rods 34 to transmit rotational force.

[0051] Specifically, the lever 33 is rotatably connected to the triangle plate 36, and the lever 33 moves the triangle plate 36. There are multiple levers 33 and triangle plate 36, and they are symmetrically arranged. Two levers 33 pass through both ends of the fixed rod 34. There are two fixed rods 34, and they are symmetrically arranged. The lever 33 rotates on the inner side of the bottom frame 14 under the drive of the rotation of the fixed rod 34, and the output end of the motor 32 is fixedly connected to the end of the fixed rod 34 on one side.

[0052] As can be seen from the above, when the height of the transfer frame needs to be adjusted, the motor 32 is started, and the motor 32 drives the fixed rod 34 to rotate. Since both ends of the conveyor belt 35 are mounted on the ends of the two fixed rods 34, the two fixed rods 34 rotate. Since the fixed rods 34 and the shift rods 33 are fixedly connected, the multiple shift rods 33 rotate on the inner side of the bottom frame 14 driven by the rotation of the fixed rods 34, thereby driving the movement of the bed frame 11 through the multiple triangular plates 36. The support rod 13 plays a supporting role and slides on the bottom plate 16 as the bed frame 11 moves. The height-adjustable design enables the transfer frame to easily adapt to the height of different medical equipment and achieve seamless docking, thereby facilitating medical staff to perform transfer operations.

[0053] Embodiment three:

[0054] See also Figure 6 - Figure 7 As shown, this embodiment is basically the same as the previous embodiment, with the difference that a motor 41 is fixedly connected to the inner side of the shaft frame 151, a paddle 42 is fixedly connected to the output end of the motor 41, both ends of the paddle 42 are rotatably connected to connecting rods 43, the motor 41 is used to provide driving force for the paddle 42, the paddle rod 33 is used to drive the two connecting rods 43 to paddle, and the connecting rod 43 is used to connect the arc rod 45.

[0055] Specifically, the motor 41 is rotatably connected to the wheel 152. When the wheel 152 rotates, the motor 41 will not rotate. Two arc rods 45 are provided and are evenly distributed on the circumference. The ends of the two connecting rods 43 are rotatably connected to the arc rods 45. When the wheel 152 rotates, the rotating plate 44 will not rotate. The motor 41, the paddle 42, the connecting rod 43, the rotating plate 44 and the arc rod 45 are all arranged inside the wheel 152.

[0056] As can be seen from the above, when the transfer frame is about to slide unexpectedly, the medical staff can start the motor 41 through the button switch. Since the output end of the motor 41 is fixedly connected to the paddle 42, the motor 41 drives the paddle rod 33 to rotate. The rotation of the paddle rod 33 drives the two connecting rods 43 rotatably connected thereon to paddle the arc rod 45 rotatably connected to the rotating plate 44, so that the arc rod 45 is tightly fitted with the inner wall of the wheel 152, increasing the friction force, performing a clamping and braking movement, locking the wheel 152, and preventing the transfer frame from continuing to move, thereby ensuring the safety of the patient.
