[0026] As shown in Figure 1 , Figure 3 and Figure 5 , the utility model provides a pass through bed type nonmagnetic stretcher car, including mobile frame 10, the stretcher main body 20 is movably arranged on mobile frame 10, and the folding guide rail 11 for supporting on the sick bed is arranged on one side of mobile frame 10, and the stretcher main body 20 moves to the sick bed along the length direction of folding guide rail 11 to form a transfer structure;
[0027] Among them, the stretcher main body 20 is composed of two groups of stretcher plates 21, and the two groups of stretcher plates 21 move along the width direction of the stretcher main body 20 to adjust the width, and the two groups of stretcher plates 21 are pulled out from the patient's body to separate.
[0028] The utility model adopts the form of movable adjustment to constitute the pass through bed type stretcher car structure, expands the translation range of the stretcher car through the form of movable splicing, builds the translation track between the sick bed, and is convenient for transferring the patient on the stretcher to the sick bed, does not need to lift the patient to reduce the discomfort of the patient, cooperates with the movable telescopic stretcher, can expand the stretcher transverse distance when being transferred to the sick bed, makes the stretcher separate from the patient's body, and completes the gentle transfer of the patient.
[0029] When transferring, the mobile frame 10 is adjusted to the corresponding height of the bed, the folding guide rail 11 is placed on the bed, the lateral movement range of the mobile frame 10 is expanded, the stretcher body 20 is moved to the bed along the folding guide rail 11, and then the stretcher plate 21 is slid to be separated from the patient, thereby realizing seamless connection between beds and achieving the purpose of zero lifting transfer.
[0030] The mobile frame 10 adopts the telescopic support of the existing non-magnetic stretcher vehicle. The existing non-magnetic stretcher vehicle has a manually adjustable lifting support, which usually adopts a screw transmission mechanism including a screw rod, a nut and a connecting rod. When the hand wheel rotates, the screw rod rotates, and the nut slides up and down along the screw rod, converting the rotary motion into linear lifting motion. The support is rotated and adjusted by hand to adjust the height. The top height of the mobile frame 10 can be adjusted to correspond to the height of the bed.
[0031] The whole body is made of high-strength aluminum alloy or non-magnetic titanium alloy material, which is free of magnetism, ensuring safe use in a strong magnetic field environment and not interfering with the normal operation of medical equipment, and is suitable for patient transfer in a strong magnetic field environment such as an MRI room of a hospital.
[0032] As shown in Figure 1 and Figure 2 , the mobile frame 10 is provided with a fixed guide rail 12, one end of the fixed guide rail 12 is rotatably connected with the folding guide rail 11 through a rotating shaft, and the folding guide rail 11 is rotatable about the connection between the folding guide rail 11 and the fixed guide rail 12, and the folding guide rail 11 is in communication with the fixed guide rail 12 after rotation.
[0033] The folding guide rail 11 is rotated to a perpendicular angle with the surface of the mobile frame 10, which is beneficial to folding and storing the folding guide rail 11. When transferring the patient, the folding guide rail 11 is rotated to a parallel position with the surface of the mobile frame 10, and one end of the folding guide rail 11 is butted with one end of the fixed guide rail 12, thereby extending the guiding distance of the fixed guide rail 12.
[0034] When in use, the folding guide rail 11 is placed on the surface of the bed, the stretcher body 20 is slid along the fixed guide rail 12 to the folding guide rail 11 and located on the bed. At this time, there may be a certain distance between the patient and the bed surface, which can be temporarily supported by placing a soft cushion or by hand. After the stretcher plate 21 is slid away from the patient, the temporary support for the patient is cancelled, and the patient is gently placed on the bed, thereby completing the transfer of the patient.
[0035] As shown in Figure 3 and Figure 4As shown, the stretcher body 20 comprises a frame 22, a fixed sleeve 221 is arranged at the inner center position of the frame 22, and an extension rod 222 is slidably connected at both ends of the fixed sleeve 221, and a fixed rod 223 is arranged on the outer wall of the extension rod 222 and penetrates the outer wall of the frame 22.
[0036] By the active translation of the extension rod 222 inside the fixed sleeve 221, the length is adjusted, which further facilitates the adjustment of the width of the stretcher body 20, and facilitates the increase of the width of the stretcher body 20 when placing the patient, until it can be smoothly separated from the outside of the patient. By adjusting the width, instead of setting the split, it is beneficial to reduce the process of repeated splicing and disassembly, reduce the process of splicing and fixing the stretcher body 20, and facilitate the adjustment and use according to the patient's body type.
[0037] A clamping block or other fixing member is arranged on the outer wall of the fixed rod 223, and when the two groups of fixed rods 223 are close after the stretcher body 20 supports the patient, the two groups of fixed rods 223 are fixed by the clamping block or the fixing member, which is convenient for subsequent transfer operation.
[0038] As shown in Figure 3 and Figure 4 The stretcher plate 21 is composed of a rod body 211 and a shovel plate 212, and the two ends of the rod body 211 are provided with a moving rod 213 fixedly connected with the extension rod 222. After the moving rod 213 slides along the length direction of the inner wall of the frame 22, the distance between the two groups of stretcher plates 21 is expanded to allow the patient to pass through.
[0039] Through the structure of the shovel plate 212, when the patient is transferred to the stretcher, first expand the distance between the two groups of stretcher plates 21, so that the two groups of stretcher plates 21 are respectively located on both sides of the patient, then move the stretcher plate 21, and insert the shovel plate 212 between the patient and the bed, and the two groups of stretcher plates 21 are placed under the patient through the shovel plate 212, which is beneficial to support the patient. Then raise the support height of the moving frame 10, slide the stretcher body 20 to transfer the patient from the bed to the moving frame 10, complete the transfer of the patient, and move the stretcher body 20 through the moving frame 10.
[0040] When the patient is transferred from the stretcher to the bed, the opposite operation is performed, and the stretcher plate 21 is slid outward until the shovel plate 212 is completely separated from the patient, so that the width between the two groups of stretcher plates 21 can pass through the patient. After the patient is transferred to the bed, the support height of the moving frame 10 is raised, and the stretcher body 20 is moved away from the patient to complete the transfer operation.
[0041] As shown in Figure 1As shown, the mobile frame 10 is provided with a fixing belt 13 on one side close to the folding guide rail 11, and a fixing ring 14 on the other side of the mobile frame 10, the fixing belt 13 is wrapped around the top of the stretcher body 20 and passes through the inside of the fixing ring 14, and then self-adheres to form a reinforcing structure.
[0042] After the stretcher body 20 is moved onto the mobile frame 10, the fixing belt 13 is wrapped around the top of the stretcher body 20, the patient is fixed on the stretcher body 20, one end of the fixing belt 13 is passed through the fixing ring 14, and then folded back to be fixed, a magic tape is arranged on the fixing belt 13, and the fixing belt 13 can be adjusted and fixed.
[0043] It is beneficial to fix the patient, reduce the shaking of the patient and the stretcher body 20 during the movement, and improve the stability and safety.
