[0021] Furthermore, to increase the friction between the fixed rod 3 and the hands of medical staff and improve the stability of the medical staff holding the fixed rod 3, the surface of each fixed rod 3 is covered with wear-resistant rubber material.

[0022] It also includes a locking block 201; a locking block 201 is fixedly connected to each fixed rod 3.

[0023] It also includes a slider 202, a sliding rod 203 and a supporting plate 204; two pairs of left-right symmetric L-shaped grooves 1002 are provided on both the front and rear sides of the bed frame 1; a transverse groove 1003 is provided at the left side of the top of each L-shaped groove 1002, and the L-shaped groove 1002 is communicated with the adjacent transverse groove 1003; a slider 202 is slidably connected to each L-shaped groove 1002; each slider 202 is slidably connected to the adjacent transverse groove 1003; a sliding rod 203 is connected to the two sliders 202 on the left side together; a sliding rod 203 is also connected to the two sliders 202 on the right side together; three supporting plates 204 are slidably connected to each sliding rod 203.

[0025] Furthermore, to expose the patient's head outside the tension-resistant fabric 5 and facilitate the patient's breathing, the rear side of the tension-resistant fabric 5 is set to be an inclined side 5002.

[0026] Furthermore, to prevent the patient from catching a cold due to getting chilled in the external environment, which may exacerbate the patient's condition, a sponge thermal insulation layer is covered on the lower surface of the tension-resistant fabric 5.

[0027] The following is a detailed description of the process of transporting the patient during the examination: Before using the bed frame 1, the tension-resistant fabric 5 is laid flat on the upper surface of the bed frame 1. At the same time, the excess fabric of the tension-resistant fabric 5 is respectively wound around the clamping plate groups 4 on the left and right sides, thus forming a storage roll 5001. Subsequently, the patient is horizontally placed on the upper side of the tension-resistant fabric 5 for the patient to lie flat and rest, and the patient's head is oriented towards the rear side of the bed frame 1. When the patient needs to undergo examinations such as CT and magnetic resonance, the ground wheels on the roller support 2 roll on the ground, enabling the bed frame 1 to move on the ground. Conveniently, two medical staff push the bed frame 1 to drive the patient to move beside the examination equipment. Then, the two medical staff stand on the front side and the rear side of the bed frame 1 respectively, and respectively hold two adjacent fixed rods 3 and lift them upward, simultaneously pulling the clamping plate group 4, the wound storage roll 5001 and the tension-resistant fabric 5 to move upward until the fixed rods 3 are disengaged from the grooves 1001 of the bed frame 1. At this time, the patient is on the upper side of the tension-resistant fabric 5, and the lower side of the patient is supported by the tension-resistant fabric 5, so that the patient moves upward until separated from the bed frame 1. Subsequently, the two medical staff hold the fixed rods 3 to translate the patient, enabling the patient to move smoothly onto the examination equipment. After the examination is completed, the medical staff hold the fixed rods 3 to move the tension-resistant fabric 5 together with the patient back onto the bed frame 1. During this process, there is no need for the medical staff to move the patient's body, thus avoiding secondary injuries caused by the change in the patient's body position, enabling the patient to move smoothly and quickly between the hospital bed and the examination equipment, improving the examination efficiency of the patient, and at the same time reducing the pain suffered by the patient during the examination.

[0028] When the bed frame 1 is not needed, with the view from left to right as the reference, by rotating the roller support 2 clockwise by 90 degrees, the roller support 2 is folded on the lower surface of the bed frame 1, so as to reduce the space occupied by the bed frame 1, thereby storing the bed frame 1 and improving the convenience of using the bed frame 1.

[0029] When the patient lies on the bed frame 1, the width of the tension-resistant fabric 5 when unfolded is usually the width of the bed, so the patient has enough room for movement. However, when the patient is being carried off the bed frame 1, too much room for movement can easily cause the patient's body position to shake or move, thus reducing the stability and safety when carrying the patient. For this reason, when the medical staff holds the fixed rod 3 and the fixed rod 3 disengages from the groove 1001, at this time the patient lies in the middle of the tension-resistant fabric 5 and has not yet disengaged from the bed frame 1. By the medical staff retracting their arms towards the middle of the bed frame 1, the distance between the two splint groups 4 is reduced. At the same time, the fixed rod 3 and the splint group 4 are adaptively rotated, so that the excess tension-resistant fabric 5 on both sides of the patient is incorporated into the storage roll 5001, making the width of the tension-resistant fabric 5 between the two splint groups 4 consistent with the space required for the patient to lie still flat, thus minimizing the room for movement of the patient during transportation, thereby reducing the amplitude of shaking and the amplitude of body position movement of the patient, and thus improving the stability and safety when carrying the patient. On this basis, when the medical staff lifts the patient, the tension-resistant fabric 5 bears the patient's gravity, making the tension-resistant fabric 5 in a taut state, so that the tension-resistant fabric 5 wound in the storage roll 5001 is easily unfolded. In this way, the fixed rod 3 is prone to rotation when held by the medical staff, so there is a situation where the fixed rod 3 disengages from the hand of the medical staff, resulting in the patient falling and causing serious secondary injuries. For this reason, when the width adjustment of the tension-resistant fabric 5 is completed, at this time the medical staff pushes the fixed rod 3, so that the two fixed rods 3 on the same splint group 4 move towards each other, so that the locking blocks 201 connected to them move towards each other, making the locking blocks 201 stuck at the connection between the storage roll 5001 and the tension-resistant fabric 5, and by squeezing the locking blocks 201 towards the inside of the storage roll 5001, the connection between the storage roll 5001 and the locking blocks 201 is recessed inward. By applying pressure to the storage roll 5001 by the locking blocks 201, the friction between the tension-resistant fabrics 5 is increased, so as to press the tension-resistant fabrics 5 tightly, thereby preventing the tension-resistant fabric 5 in the storage roll 5001 from continuing to unfold under force, thus ensuring that the fixed rod 3 will not rotate when held, and improving the safety of carrying the patient. Here it is noted that the friction between the fixed rod 3 and the hand of the medical staff is increased by the wear-resistant rubber material covering the surface of the fixed rod 3, so as to improve the stability of the medical staff holding the fixed rod 3. And when the patient does not need to be carried, at this time the two storage rolls 5001 are respectively located on the left and right sides of the bed frame 1. At this time, by winding the storage roll 5001, the tension-resistant fabric 5 on the bed frame 1 is in a straight state, and then the locking blocks 201 are stuck at the connection between the storage roll 5001 and the tension-resistant fabric 5, so as to prevent the tension-resistant fabric 5 on the storage roll 5001 from unfolding outward. In this way, the tension-resistant fabric 5 can always be kept in a straight state on the bed frame 1, avoiding wrinkles in the tension-resistant fabric 5 caused by the movement of the patient or the medical staff changing dressings, thus improving the comfort of the patient when lying flat.

[0030] On this basis, when the patient lies on the bed frame 1 to rest, Figure 5 As shown, the support plate 204 is in a horizontal state and is located on the upper surface of the tension-resistant fabric 5, and the support plate 204 is located above the adjacent storage roll 5001, so that some patients can put their hands or feet on the support plates 204 on both sides of the bed frame 1, thereby increasing the range of movement of the patient's body and improving the comfort of the patient lying on the bed frame 1. It is explained here that the state of the slide bar 203 is limited by inserting the latch 205 between the slide bar 203 and the slider 202, thereby ensuring that the support plate 204 is always in a horizontal state, and when the patient lies on the bed frame 1, The medical staff pulls the handle 20301 to drive the sliders 202 to move toward each other on the L-shaped groove 1002, and removes the latch 205, so that the slide bar 203 can rotate on the adjacent slide bar 202, and then drives the slide bar 203 and the support plate 204 to rotate by hand-cranking the handle 20301, so that the support plate 204 rotates to an upward vertical state, and reinserts the latch 205 to lock the support plate 204 in the vertical upward state, forming a fence on both sides of the bed frame 1, thereby protecting the patient lying flat on the bed frame 1 and preventing the patient from accidentally falling from the bed frame 1 and causing injury.

[0031] Due to hygienic requirements, there is a need to regularly replace the strain cloth 5. When using conventional methods to replace the strain cloth 5, it is usually necessary to move the patient away from the bed frame 1. Inevitably, the patient needs to move, which may cause the injured part to be pulled, exacerbating the patient's pain. Therefore, when it is necessary to replace the strain cloth 5, the patient needs to lie flat in the middle of the strain cloth 5. Then, with the assistance of medical staff, the patient is slowly turned, that is, the left half of the body is lifted to separate the left half of the patient's body from the strain cloth 5. At the same time, the left slider 202 is pushed towards the middle of the bed frame 1 until the left slider 202 moves to the rightmost end of the corresponding L-shaped groove 1002, so as to push the horizontally placed support plate 204 under the left half of the patient's body. Subsequently, assist the patient to lie flat. Then, in the same operation method as above, the right support plate 204 is pushed under the right half of the patient's body. Then, two medical staff stand on the front and rear sides of the bed frame 1 respectively, and hold the two handles 20301 respectively. Then, the handles 20301 are lifted upward to move the slider 202, the slide rod 203, and the support plate 204 upward, lifting the patient carried by the support plate 204 upward to separate the patient from the strain cloth 5. Then, all the handles 20301 are pulled synchronously to the left to make all the sliders 202 snap into the transverse groove 1003. The transverse groove 1003 blocks the sliders 202 from sliding downward, so as to lift and suspend the patient above the strain cloth 5. Then, the fixing rod 3 is taken out from the groove 1001, and the two fixing rods 3 on the same splint group 4 are moved away from each other. In this way, the locking block 201 is separated from the storage roll 5001. Then, all the strain cloth 5 in the storage roll 5001 is unfolded. At this time, the end of the strain cloth 5 is clamped by the two pressing plates of the splint group 4. At this time, continue to move the two fixing rods 3 away from each other until the pressing surface 4001 is separated from the corresponding pressing groove 3001. In this way, the two pressing plates lose the extrusion of the pressing groove 3001, and thus lose the extrusion of the strain cloth 5 between the two pressing plates, facilitating the extraction of the strain cloth 5 from between the two pressing plates. In this way, the strain cloth 5 can be removed from the splint group 4. Then, the dirty strain cloth 5 is pulled out from under the patient, and the clean strain cloth 5 is re-laid in the middle of the bed frame 1. Then, the edges of the strain cloth 5 are sequentially reinserted into the two pressing plates, and the two fixing rods 3 are controlled to move towards each other to make the pressing surface 4001 re-enter the pressing groove 3001, so that the two pressing plates re-press the edges of the strain cloth 5. Subsequently, the splint group 4 is rotated to wind the strain cloth 5 into a storage roll 5001. After the locking block 201 is stuck on the storage roll 5001, the fixing rod 3 is re-inserted into the groove 1001. In this way, the new strain cloth 5 is re-laid flat on the bed frame 1. Then, the medical staff hold the handle 20301 and drive the handle 20301 to move uniformly to the right to make the slider 202 disengage from the transverse groove 1003. Then, the handle 20301 is slowly lowered to make the patient slowly fall on the surface of the new strain cloth 5. Then, the support plates 204 are sequentially removed from under the patient.Move the slider 202, the sliding rod 203, and the supporting plate 204 to their initial positions. Compared with the conventional method of replacing the strain cloth 5, by temporarily supporting the patient with the supporting plate 204, the patient is suspended above the strain cloth 5, so as to replace the dirty strain cloth 5 without moving the patient, eliminating the secondary injury caused by additional movement. At the same time, by adjusting the distance between the extrusion groove 3001 of the fixing rod 3 and the extrusion surface 4001 of the splint group 4, the quick fixing and disassembly of the splint group 4 on the strain cloth 5 can be realized, thus improving the efficiency of replacing the strain cloth 5.,

[0032] On this basis, since there is a situation where the patient needs to be transferred over a long distance, for example, when the patient needs to be transported to another hospital by ambulance, when the ambulance passes through turning and bumpy sections, the patient is prone to move due to inertia, which is likely to cause discomfort to the patient. Therefore, when a long-distance transfer is required, first remove the pin 205 between the slider 202 and the sliding rod 203, so that the sliding rod 203 can rotate freely within the slider 202, as Figure 1 shown. By the medical staff turning the handle 20301, the supporting plate 204 is in a vertically downward state, and the supporting plate 204 is located outside the adjacent storage roll 5001. At this time, the medical staff hold the fixing rods 3 on both sides and drive the splint group 4 to move upward, and unfold the storage rolls 5001 on both sides. At this time, the patient lies in the middle of the strain cloth 5. Then place the left fixing rod 3 and the splint group 4 in the right groove 1001, so that the strain cloth 5 unfolded from the left storage roll 5001 covers the patient. Then place the right fixing rod 3 and the splint group 4 in the left groove 1001, so that the strain cloth 5 unfolded from the right storage roll 5001 covers the patient. Subsequently, the strain cloth 5 is wound up by rotating the splint groups 4 on both sides until the strain cloth 5 on the patient's body is in a straightened state. In this way, the patient is fixed to the bed frame 1 by the strain cloth 5, preventing the patient's body position from moving when passing through turning or bumpy sections, thus causing discomfort to the patient. On this basis, when the strain cloth 5 wraps the patient, at this time the patient's head faces the rear side of the bed frame 1. By setting the rear side of the strain cloth 5 as an inclined side 5002, the patient's head is exposed outside the strain cloth 5, facilitating the patient's breathing. And because the lower surface of the strain cloth 5 is covered with a sponge thermal insulation layer, wrapping the patient with the strain cloth 5 can keep the patient's body temperature, preventing the patient from catching a cold due to getting cold in the external environment and thus aggravating the patient's condition. Here it is noted that before the bed frame 1 is moved into the ambulance, the roller bracket 2 can be folded, so as to reduce the space occupied by the bed frame 1 and facilitate the bed frame 1 to enter the ambulance.

[0033] For the regular replacement of the strain insulator fabric 5, generally, it is necessary to rely on nurses to record the replacement time nodes, determine the replacement cycle, and avoid the phenomenon of overusing the strain insulator fabric 5. Then, it is entered into the hospital system, which is relatively inconvenient. By installing an intelligent information module on the bed frame 1, the replacement time nodes can be directly input on-site through the intelligent information module installed at the head of the bed frame 1 and uploaded and saved into the hospital system. Moreover, time information such as dressing change time nodes and drug injections can be recorded through the intelligent information module and directly synchronized to the hospital system, improving the medical convenience.

[0034] Embodiment 2 Based on Embodiment 1, as Figure 6 and Figure 8 shown, each supporting plate 204 is set to be composed of three bottom plates, and each sliding rod 203 is provided with a limiting block 20302; the three bottom plates of the same supporting plate 204 are all set to be slidable on the adjacent limiting blocks 20302.

[0035] Since the injured parts of patients are different, during the process of supporting patients by the supporting plate 204, there may be a situation where the supporting plate 204 fits the injured part of the patient, which will increase the pain of the patient. Therefore, by setting each supporting plate 204 to be composed of three bottom plates, the distance between the bottom plates can be adjusted by medical staff, so that the gap between the bottom plates is aligned with the injured part of the patient, thus avoiding the situation where the supporting plate 204 fits the injured part of the patient, thereby improving the comfort of the patient. Moreover, since the heights of each patient are different, by adjusting the distance between the three bottom plates, it is convenient for the three bottom plates to respectively support the head, back and feet of the patient adaptively, so that the distance between the bottom plates can be adjusted adaptively according to the body types of different patients, improving the applicability of the bottom plates.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes may be made therein without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
