Description

Technical Field

[0001] The present invention belongs to the field of medical equipment, and in particular relates to a medical bed used for patient transfer and treatment and a method of using the same. Background Art

[0002] Hospitals usually use transfer beds (or transfer carts) when transferring patients from wards to operating rooms or from surgery back to wards, which can ensure the safety and comfort of patients during the transfer process. However, ordinary transfer beds (or transfer carts) are independent units. When transferring patients from transfer beds (or transfer carts) to treatment beds (or operating tables) or from treatment beds (or operating tables) to transfer beds (or transfer carts), medical staff still need to manually carry them. This process is not only time-consuming and labor-intensive, but also very likely to cause secondary injuries to patients. Especially when encountering patients in anesthesia or other conditions that have lost their ability to move independently, the transportation process becomes more difficult and dangerous.

[0003] Although there are many transfer beds (or transfer carts) that can be docked with treatment beds (or operating tables), which can reduce the labor intensity of medical staff and the risk of secondary injuries to patients during the transfer process to a certain extent, most of the existing solutions only move patients between the transfer bed (or transfer cart) and the treatment bed (or operating table) through various mechanisms. They have complex structures, high manufacturing and maintenance costs, and inconvenient operations. In addition, they do not fundamentally eliminate various risks that may occur during the transfer process, such as failure of the motion mechanism, failure of components, and inability to quickly separate the patient from the treatment bed (or operating table) in an emergency.

DETAILED DESCRIPTION

[0046] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0047] It should be noted that the terms such as "upper", "lower", "left", "right", "middle" and "one" etc. used in this specification are only for the convenience of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships, without substantially changing the technical content, should also be regarded as the scope of implementation of the present invention.

[0048] Before describing the embodiments of the present invention in detail, the application environment of the present invention is described first. The technology of the present invention is mainly applied to the transfer and treatment of patients, especially to the clinical application of prone high-intensity focused ultrasound (HIFU) treatment of female breast diseases. The present invention solves the problems of frequent movement of patients during treatment, inconvenient patient positioning, high labor intensity, and low patient comfort.

[0049] like Figures 1 to 6 As shown, the medical bed for patient transfer and treatment of the present invention comprises a treatment bed 2 and a transfer bed 1 that can be docked and separated, a guide mechanism for guiding when the two are connected is provided between the transfer bed 1 and the treatment bed 2, and a transfer bed locking mechanism 5 is provided between the transfer bed 1 and the treatment bed 2, and the transfer bed locking mechanism 5 is used to lock when the transfer bed 1 and the treatment bed 2 are docked and unlock when they are separated. It is convenient to accurately realize the rapid docking of the transfer bed 1 and the treatment bed 2, and the operation is simple and convenient, and the safety performance is high.

[0050] like Figure 1 , Figure 2 and Figure 6 As shown, in some exemplary embodiments, the transfer bed 1 includes a bed body 12 and a bed frame 11. A walking mechanism 13 is provided at the lower end of the bed frame 11. The walking mechanism 13 can be a universal caster with a brake pedal. The universal caster is locked or unlocked by the brake pedal, forming a double protection with the transfer bed locking mechanism to prevent the transfer bed from moving by itself. The transfer bed 1 is laterally translated to dock or separate with the treatment bed 2, and when docked, the bed body 12 is located above the treatment bed 2. The transfer bed 1 is easy to transfer. When the transfer bed 1 is docked with the treatment bed 2, it is convenient to directly treat the patient without the need for frequent movement of the patient.

[0051] like Figure 1 and Figure 2 As shown, in an exemplary embodiment, a reversible pedal is provided on the transfer bed 1 to assist the patient in getting on and off the bed. When in use, the reversible pedal is turned outward and opened, and the patient can use the pedal to get on and off the bed. After use, the reversible pedal is folded inward and put away. The pedal can be put away freely without occupying external space. The transfer bed is provided with a plug-in infusion stand and a urine bag hook to facilitate intravenous drip and urine discharge for patients.

[0052] like Figure 1 , Figure 2 and Figure 6As shown, in some exemplary embodiments, a treatment window 22 is provided on the treatment bed 2, and a treatment hole 14 corresponding to the treatment window 22 is provided on the bed body 12 of the transfer bed 1, so that the patient can be directly treated without changing body position or moving. For example, when treating breast diseases, an ultrasonic treatment head is installed in the treatment window 22, and the breast on the side to be treated can directly enter the treatment window 22 through the treatment hole 14 for treatment, which is fast and convenient in positioning and improves treatment efficiency.

[0053] like Figure 5 As shown, in an exemplary embodiment, the bed frame 11 partially extends under the treatment bed 2 .

[0054] like Figure 5 As shown, in an exemplary embodiment, the guide mechanism includes a docking guide channel 21 provided on the side wall of the treatment bed 2, and the bed frame 11 of the transfer bed 1 may be a C-shaped structure. When docking, the opening of the bed frame 11 faces the treatment bed 2, and the lower end of the bed frame 11 is guided and matched with the docking guide channel 21, and the lower end of the bed frame 11 partially extends into the docking guide channel 21. In this embodiment, the lower end portion of the bed frame 11 may be a portion of the bed frame 11 on which the walking mechanism 13 is installed, and the walking mechanism 13 slides into the docking guide channel 21, so that docking is simple and convenient. With this structural design, the bed frame 11 itself cooperates with the docking guide channel 21 to simplify the structure, reduce the occupied space, and reduce the requirements for the use environment.

[0055] like Figure 1 and Figure 2 As shown, in an exemplary embodiment, when the transfer bed 1 is docked with the treatment bed 2, the bed frame 11 is located outside the treatment bed 2, which reduces interference with the inside of the treatment bed 2, and the docking is simple and has high versatility.

[0056] like Figures 1 to 4 , Figure 6 As shown, in some exemplary embodiments, the guide mechanism includes a guide plate 3 and a first guide wheel group 4 that is slidably matched with the guide plate 3. One of the guide plate 3 and the first guide wheel group 4 is installed on the bed frame 11 of the transfer bed 1, and the other is installed on the treatment bed 2, that is, when the guide plate 3 is installed on the bed frame 11, the first guide wheel group 4 is installed on the treatment bed 2; when the guide plate 3 is installed on the treatment bed 2, the first guide wheel group 4 is installed on the bed frame 11. The structure is simple, the assembly is convenient, the guidance is stable, and the difficulty of operation during the docking process is effectively reduced, and the labor intensity is reduced.

[0057] like Figures 1 to 4 As shown, in an exemplary embodiment, the guide plate 3 is installed on the two inner sides of the bed frame 11, and the first guide wheel group 4 is installed on the lower part of the outer sides of both ends of the treatment bed 2. The installation is convenient, the docking guide is simple and stable, and the influence of the first guide wheel group on the overall layout and appearance of the treatment bed 2 is reduced.

[0058] like Figure 5 As shown, in an exemplary embodiment, the guide plate 3 can be a straight plate structure, and one end of the straight plate structure is provided with an inclined surface 31 for guiding when contacting the first guide wheel group, and an angle θ1 greater than 0° is formed between the inclined surface 31 and the first guide wheel group. This structural design makes it more convenient for the guide plate and the first guide wheel group to dock and guide.

[0059] like Figure 5 As shown, in an exemplary embodiment, the first guide wheel group includes a large guide wheel group and a small guide wheel group, the diameter of the first roller 41 in the large guide wheel group is larger than the diameter of the second roller 42 in the small guide wheel group, and during docking, the wheel surface of the first roller 41 contacts the guide plate 3 before the wheel surface of the second roller 42, that is, during docking, the guide plate 3 first contacts the first roller 41. The large guide wheel group has a stronger ability to withstand impact, and the small guide wheel group and the guide plate are more closely matched. The structural design is adopted so that the front section controls the guidance and the rear section controls the matching accuracy, and the entire docking guidance is smoother, which is conducive to controlling the matching gap, improving the accuracy of docking, and positioning is more accurate, while also extending the service life.

[0060] like Figure 5 As shown, in an exemplary embodiment, the large guide wheel group includes at least one first roller 41, and the wheel surface of the first roller adjacent to the small guide wheel group facing the guide plate 3 is flush with the wheel surface of the second roller 42 facing the guide plate 3, so that the impact of the guide plate is first buffered by the first roller, making the structure more stable and reliable.

[0061] like Figure 2 , Figure 5 and Figure 6 As shown, in an exemplary embodiment, the number of first rollers 41 is two or more, and each first roller 41 is spaced apart along the lateral translation direction of the transfer bed 1, and the wheel surface of each first roller 41 facing the side of the guide plate 3 gradually approaches and contacts the side wall of the guide plate 3 in the order of contact with the guide plate 3, that is, during docking, the distance between the wheel surface of the first roller that first approaches the guide plate and the guide plate is greater than the distance between the wheel surface of the first roller that later approaches the guide plate and the guide plate, so that the guide plate 3 gradually contacts and fits with the large guide wheel group. The center line of each first roller forms an angle θ2 greater than 0° with the guide plate 3. The use of this structural design is conducive to further better docking guidance and improves the smoothness and accuracy of the docking process.

[0062] like Figure 5As shown, in an exemplary embodiment, the guide wheel group includes at least one second roller 42. When the number of the second rollers 42 is two or more, the second rollers are spaced apart along the direction of the lateral translation of the transfer bed, so that the first guide wheel group and the guide plate fit more closely, the guidance is smoother, the accuracy is higher, and the stability and reliability of the docking between the transfer bed and the treatment bed are improved.

[0063] like Figures 1 to 6 As shown, in an exemplary embodiment, each roller of the first guide wheel group can be a polyurethane wheel, a PU rubber-coated wheel or other rollers with a flexible surface, which is helpful in buffering the impact force of the docking process, making the docking process quiet, smooth, comfortable and safe.

[0064] like Figures 1 to 6 As shown, in some exemplary embodiments, the transfer bed locking mechanism 5 can be an electromagnetic lock, which includes a lock core 51 installed on the treatment bed 2 and an adsorption plate 52 installed on the transfer bed 1. A trigger assembly is arranged between the transfer bed 1 and the treatment bed 2. The trigger assembly includes a contact switch 61 installed on the treatment bed 2 and a trigger plate 62 installed on the transfer bed 1. After docking, the trigger plate 62 triggers the contact switch 61, and the electromagnetic lock locks the transfer bed 1 and the treatment bed 2. The lock core 51 and the contact switch 61 are installed on the treatment bed 2, which is convenient for taking power from the treatment bed. The adsorption plate 52 and the trigger plate 62 are installed on the transfer bed 1, which is convenient to carry and does not require an independent power supply. The adsorption plate and the trigger plate are simple to install and maintain, and are not easy to affect the overall layout of the transfer bed, and the appearance is neat. In this embodiment, the trigger assembly is a mechanical contact switch, and a capacitive or other form of contact switch can also be selected.

[0065] like Figures 1 to 4 As shown, in an exemplary embodiment, the lock core 51 of the electromagnetic lock is close to the contact switch 61 of the trigger assembly and is installed in the middle and upper part of the treatment bed 2. The adsorption plate 52 and the trigger plate 62 are installed on the bed frame 11. The center of gravity of the transfer bed 1 is distributed in the middle and upper part of the transfer bed. The electromagnetic lock is distributed near the center of gravity of the transfer bed 1, so that the docking fixation is more stable. The electromagnetic lock and the trigger assembly are installed close to each other, which is conducive to matching and alignment, can reduce the influence of processing errors and assembly errors on the sensitivity of the trigger assembly, and improve the stability of locking and unlocking.

[0066] In an exemplary embodiment, an external control system can provide a signal for the transfer bed and the treatment bed to be docked, fixed, or disconnected; when docked, the transfer bed will trigger a contact switch, which will transmit a signal to the control system. After receiving the signal, the control system will immediately power on the electromagnetic lock, and the electromagnetic lock will work to tightly adsorb the transfer bed and the treatment bed together; if the electromagnetic lock is accidentally powered off during the treatment, the transfer bed will be separated from the treatment bed. When the transfer bed moves beyond the contact switch stroke, the contact switch will send a disconnection signal to the control system again. After receiving and judging the signal, the control system will immediately stop the operation of the relevant equipment and send out an audible and visual alarm to remind medical staff of the system failure, thereby ensuring the safety of the docking process and the treatment process. After the treatment is completed, the doctor uses the computer to operate the control system to stop the electromagnetic lock and prompt that the transfer bed and the treatment bed have been disconnected, which improves the automation and intelligence of the equipment and reduces the risk of human error.

[0067] like Figures 7 to 9 As shown, a bed surface kit is installed on the bed body 12, and the bed surface kit includes a positioning pad 73 and / or an angle adjustment component, that is, only includes the positioning pad 73, or only includes the angle adjustment component, or includes the positioning pad and the angle adjustment component at the same time. Among them, the positioning pad 73 is placed on the bed body 12 and covers the treatment hole 14. The positioning pad 73 is provided with a positioning hole 731 for positioning the breast on the side to be treated. During treatment, the breast on the side to be treated passes through the positioning hole 731 and enters the treatment hole 14. The angle adjustment component is arranged on the bed body 12, and is used to support the trunk on the non-treatment side during treatment, and can adjust the inclination angle of the patient's body by changing the lifting height of the trunk on the non-treatment side, so that the patient's trunk to be treated is close to the bed body 12, which is conducive to the breast to fully enter the treatment hole 14.

[0068] like Figures 7 to 9 As shown, in an exemplary embodiment, the center line of the positioning hole 731 coincides with the center line of the treatment hole 14, and one side of the positioning hole 731 extends outward to form an auxiliary operation hole. The positioning hole and the auxiliary operation hole can form a pear-shaped hole or a gourd hole. The positioning hole 731 can be the large end of the pear-shaped hole, and the auxiliary operation hole can be the small end of the pear-shaped hole. With this structural design, the positioning of the breast to be treated is more accurate, and while effectively preventing other tissues from entering the treatment hole 14, it provides an operating space for the doctor. The doctor can reach in from the auxiliary operation hole with one hand to adjust the breast shape, sense the breast epidermal temperature, confirm the location of the lesion, etc., which helps to reduce the treatment time, improve the treatment efficiency and the safety of the treatment process.

[0069] like Figure 7As shown, in an exemplary embodiment, the outer contour of the positioning pad 73 includes two straight edges, the two straight edges are parallel and aligned, and an outwardly convex arc structure is formed between the ends of the two straight edges. The hole shape of the second opening 721 matches the outer contour of the positioning pad 73. When the other breast needs to be treated, the positioning pad 73 only needs to be rotated 180° along its circumference to adapt to the treatment, which not only improves the versatility, but also prevents the positioning pad 73 from rotating arbitrarily along its circumference, thereby improving the stability during the treatment process.

[0070] like Fig.10 and Fig.11 As shown, in an exemplary embodiment, the angle adjustment component is a lifting mechanism that can be translated on the bed board, and the lifting mechanism drives the lifting of the non-treatment side torso, thereby adjusting the inclination angle of the patient's body. For example, the lifting mechanism includes a cushion body and a lifting drive 754 installed in the cushion body. The lifting drive 754 can be a lifting cylinder or other retractable structure. The cushion body includes a bottom plate 753 and a top plate 752 connected to the bottom plate 753, and the top plate provides flexible support for the non-treatment side torso of the patient. The bottom plate 753 and the top plate 752 can be connected to form a V-shaped structure, and the connection between the top plate 752 and the bottom plate 753 is a flexible connection or a rotation connection, which can make the top plate flexible to flip under force. A first avoidance opening 755 for avoiding the breast is provided on the top plate 752, and the top plate 752 is driven by the lifting drive 754 to flip around the connection between the top plate 752 and the bottom plate 753 to adjust the height of the non-treatment side torso of the patient, thereby adjusting the inclination angle of the patient's body. The base of the lifting drive member 754 can be installed on the bottom plate 753, and the output end of the lifting drive member is hinged to the top plate, or directly supports the top plate to drive the top plate to flip.

[0071] In an exemplary embodiment, the angle adjustment component may also be an air bag, and the height of the non-treatment side torso of the patient may be adjusted by changing the inflation volume of the air bag.

[0072] like Figures 7 to 9 As shown, in an exemplary embodiment, the angle adjustment component 75 is an adjustment pad that can be translated on the bed 12. By changing the position of the torso on the non-treatment side supported by the adjustment pad, the inclination angle of the patient's body can be adjusted. In this embodiment, the adjustment pad can be placed on the soft pad 72 to provide flexible support for the torso on the non-treatment side. The adjustment pad is moved and adjusted along the width direction of the bed 12 (i.e., the X direction in the figure) to change the angle α of the non-treatment side pad, so as to adapt to different treatment needs.

[0073] like Figures 7 to 9As shown, in an exemplary embodiment, the angle adjustment component 75 is an adjustment pad, and the inner side of the adjustment pad is provided with a second avoidance opening 751 for avoiding the breast, so as to avoid compression of the breast on the non-treated side. The top of the adjustment pad is an inclined surface, and the inclined surface gradually decreases from the outside to the inside. Among them, the angle adjustment component 75 may include two symmetrical left breast adjustment pads and right breast adjustment pads, which have a higher matching degree. When using, you can choose the adjustment pad corresponding to the non-treated breast; or the angle adjustment component 75 may include an adjustment pad, which is a symmetrical structure, and the left and right breasts share one adjustment pad, which has high versatility. When in use, it can be rotated 180° to adapt to the other breast. The use of the adjustment pad can also provide certain support for the patient's shoulders and waist, which is conducive to relieving fatigue of the non-treated shoulder.

[0074] like Figure 7 As shown, in an exemplary embodiment, a support plate 71 is provided on the bed body 12, and the support plate 71 is located below the positioning pad 73 to provide support for the upper torso of the patient. The support plate 71 is provided with a first opening 21 corresponding to the treatment hole 14, and the top surface height of the support plate 71 gradually decreases from the outside to the inside. The top surface structure increases the force-bearing area, avoids local pressure on the chest wall and the ribs, and improves the patient's comfort.

[0075] like Figure 7 As shown, in an exemplary embodiment, the bottom of the support plate 71 is folded downward to have a flange structure for connecting to the bed body 12, and the flange structure is supported on the edge of the treatment hole 14. In this embodiment, the support plate 71 can be an annular structure, and the flange structure is arranged at the edge of the outer ring. The support plate 71 is installed on the bed body 12, and is embedded and matched with the treatment hole 14 on the bed body 12 through the flange structure, and is limited by the step surface at the edge of the treatment hole 14. After the support plate 71 and the bed body 12 are assembled, the highest point of the upper surface of the support plate 71 can be flush with the upper surface of the bed body 12, and the assembly is simple and convenient, and the structure is stable. The support plate 71 and the bed body 12 can be connected by a detachable connection method such as embedding, bolt connection, etc., so that the support plate 71 and the bed body 12 can be manufactured separately, which is conducive to manufacturing a support plate of appropriate thickness according to demand. For example, the support plate 71 is thinned, and the thickness of the support plate 71 is less than the thickness of the bed body 12. The use of a thinner support plate can reduce the space occupied by the support plate 71, so that the breast tissue on the side to be treated can fully fall into the focus range of the ultrasonic treatment head under the support plate, thereby improving the treatment effect. In this embodiment, the ultrasonic treatment head is installed below the treatment hole 14, and the breast on the side to be treated enters the focus range of the ultrasonic treatment head after passing through the treatment hole 14.

[0076] like Figures 7 to 9As shown, in an exemplary embodiment, the bed surface kit also includes a cushion 72, which is installed on the bed body 12.

The upper surface of the protrusion 741 is flush with the upper surface of the cushion 72, and the protrusion 741 supports the patient's neck. With this structural design, the head pad 74 is partially sunken to prevent the neck from being stretched laterally, and when providing flexible support for the patient's head, it is helpful to relieve the patient's neck fatigue and prevent neck fatigue injury. In this embodiment, the protrusion 741 can be an arc-shaped structure, which is conducive to fitting with the neck and improving comfort. The head pad 74 is easy to take out from the bed body 12 and the cushion 72, which is conducive to replacing head pads of different thickness specifications according to different patients; or the lifting height of the head pad can be adjusted by installing a lifting mechanism on the bed board.

[0079] like Figures 7 to 9 As shown, in an exemplary embodiment, the bed surface kit further includes a foot pad 76 for supporting the patient's feet. The foot pad 76 is placed on the soft cushion 72. The foot pad helps the patient's legs to maintain a natural posture and prevents fatigue injuries to the legs.

[0080] like Figures 7 to 9As shown, in an exemplary embodiment, the positioning pad 73, the adjustment pad, the soft pad 72, the head pad 74, and the foot pad 76 cooperate with each other to provide flexible support for various parts of the patient's body, so as to reduce the patient's local pressure feeling, improve the patient's comfort and tolerance, and make the breast tissue on the side to be treated more accurately and fully exposed to the ultrasonic treatment head. The positioning pad 73, the adjustment pad, the soft pad 72, the head pad 74, and the foot pad 76 can be made of any one of EVA foam, space memory foam, PVC foam or gel, which is conducive to ensuring the stability of the patient's body posture and improving comfort.

[0081] like Figures 7 to 9 , Fig.12 As shown, in an exemplary embodiment, the bed surface kit also includes a fixing belt assembly 77 for fixing the patient's torso. The two ends of the fixing belt assembly 77 are respectively connected to the two sides of the width direction of the bed body 12, and can be moved along the length direction of the bed body 12 to adjust the position of the fixing belt assembly pressing the patient's torso, so as to adapt to patients of different heights. The fixing belt assembly generally presses the patient's back to fix the patient's torso. The fixing belt assembly 77 cooperates with the soft pad 72, the positioning pad 73, and the angle adjustment component 75 to keep the patient in a good and fixed position, thereby improving the safety of the treatment process. The fixing belt assembly 77 can also be adjusted in length along the length direction of the fixing belt assembly to adapt to different patients. In this embodiment, the fixing belt assembly 77 includes an adjusting belt 772, and the two ends of the adjusting belt 772 are provided with a length adjustment structure, which can be a Velcro, which is easy to stick and fasten, and is conducive to quickly adjusting the tightness; the adjusting belt 772 is provided with a strip soft belt 771, and the strip soft belt 771 can slide and adjust the position along the length direction of the adjusting belt, thereby adjusting the position in contact with the patient's body and improving the comfort of the patient's back; the two ends of the adjusting belt are provided with sliders 773, and the connection position of the slider 773 and the bed body 12 is adjusted to adjust the position of the fixing belt. Among them, the slider 773 can be connected with the slide groove 121 on both sides of the bed body 12, and the slide groove 121 is arranged along the length direction of the bed body 12 (i.e., the Y direction in the figure), and the slider 773 slides along the slide groove 121 to adjust the position of the fixing belt assembly 77; or the two sides of the bed board are provided with multiple card slots along its length direction, and the slider 773 is engaged with the card slots at different positions, thereby adjusting the position of the fixing belt assembly 77.

[0082] like Figure 5 , Figures 13 to 16As shown, in an exemplary embodiment, an X-direction translation mechanism 81 for adjusting the X-direction translation of the bed 12 relative to the bed frame 11 and a Y-direction translation mechanism 82 for adjusting the Y-direction translation are provided between the bed 12 and the bed frame 11, and a bed locking mechanism 84 is provided between the bed 12 and the bed frame 11, and the bed locking mechanism 84 is used to lock or unlock the bed 12 and the bed frame 11. The bed 12 can be horizontally moved relative to the bed frame 11 through a simple structure, and locked through the bed locking mechanism, so that the position of the patient on the bed 12 can be adjusted according to needs, and the movement and adjustment are smooth.

[0083] like Figure 5 , Figures 13 to 15 As shown, in this exemplary embodiment, the width direction of the bed 12 is the X direction, and the length direction of the bed 12 is the Y direction.

[0084] like Figure 5 , Figures 13 to 15 As shown, in an exemplary embodiment, an X-direction translation mechanism 81 and a Y-direction translation mechanism 82 are installed at both ends of the bottom of the bed 12, and the treatment hole 14 is located between the translation mechanisms at both ends of the bed. The X-direction translation mechanism 81 and the Y-direction translation mechanism 82 are arranged at both ends of the bed 12, which is conducive to the translation mechanism at one end being mainly used for guidance, and the translation mechanism at the other end being mainly used for load bearing, thereby ensuring the stability of the structure and the guidance accuracy.

[0085] like Figure 5 , Figures 13 to 15 As shown, in an exemplary embodiment, the bed 12 is connected to the X-direction translation mechanism 81 via the Y-direction translation mechanism 82, and the X-direction translation mechanism 81 is connected to the bed frame 11. The bed 12 translates along the Y-direction on the Y-direction translation mechanism 82, and the bed 12 and the Y-direction translation mechanism 82 translate along the X-direction on the X-direction translation mechanism 81 together, thereby achieving the X-direction and Y-direction translation adjustment of the bed 12, so as to fine-tune the alignment accuracy of the treatment hole and the treatment window.

[0086] like Figure 5 , Figures 13 to 15As shown, in an exemplary embodiment, the X-direction translation mechanism 81 can be a linear guide pair, and the Y-direction translation mechanism 82 can be a linear guide pair or a track roller group. That is, the X-direction translation mechanism and the Y-direction translation mechanism are both linear guide pairs, and the Y-direction translation mechanism can be a linear guide pair or a track roller group. The linear guide pair has good guiding performance, and the track roller group has strong adaptability, which is convenient for adjusting the assembly gap. The cooperation between the linear guide pair and the track roller group reduces the difficulty of manufacturing and assembly, while improving the reliability and safety of the equipment operation, and reducing the assembly and maintenance costs. Among them, the X-direction translation mechanism and the Y-direction translation mechanism at the head and tail ends of the bed 12 can select linear guide pairs or track roller groups according to needs, and the number of translation devices can also be selected according to needs. The distribution directions of each X-direction translation mechanism are parallel, and the distribution direction of each Y-direction translation mechanism is translational. In this embodiment, two groups of X-direction translation mechanisms and two groups of Y-direction translation mechanisms are provided at the tail end of the bed, and both the X-direction translation mechanism and the Y-direction translation mechanism are linear guide pairs; a group of X-direction translation mechanisms and a group of Y-direction translation mechanisms are provided at the head end of the bed, and the X-direction translation mechanism is a linear guide pair, and the Y-direction translation mechanism is a track wheel group. The Y-direction translation mechanism at the tail end of the bed is a linear guide pair, and the Y-direction translation mechanism at the head end of the bed is a track wheel group, which can effectively avoid movement jamming caused by excessive parallelism deviation due to long-span segmented assembly, and reduce assembly difficulty and cost.

[0087] like Figure 5 , Figures 13 to 15 As shown, in an exemplary embodiment, the linear guide pair includes a linear guide and a slider slidably mounted on the linear guide; the slider and the linear guide of the X-axis translation mechanism are respectively connected to the Y-axis translation mechanism and the bed frame, and the slider and the linear guide of the Y-axis translation mechanism are respectively connected to the bed body and the X-axis translation mechanism. For example, the slider of the X-direction translation mechanism is the X-direction slider 812, the number of the X-direction slider 812 is greater than one, and can be set according to requirements. In this embodiment, each X-direction translation mechanism is provided with two X-direction sliders, and the linear guide of the X-direction translation mechanism is the X-direction linear guide 811; the slider of the Y-direction translation mechanism is the Y-direction slider 822, the number of the Y-direction slider 22 is greater than one, and can be set according to requirements. In this embodiment, each Y-direction translation mechanism is provided with two Y-direction sliders, and the linear guide of the Y-direction translation mechanism is the Y-direction linear guide 821; during installation, the bed body 12 is connected to the Y-direction slider 822 through the Y-direction slider fixing plate, the Y-direction linear guide 821 is installed on the X-direction translation mechanism through the Y-direction guide mounting plate 823, the Y-direction guide mounting plate 823 is connected to the X-direction slider 812 through the X-direction slider fixing plate, and the X-direction linear guide 811 is connected to the bed frame 11 through the X-direction guide mounting plate 813. The structure is simple, the installation is convenient, the operation is stable, and the sliding has good guiding performance.

[0088] like Figure 5 , Figures 13 to 15As shown, in an exemplary embodiment, the track roller group includes a roller mounting seat 824 connected to the bed 12, and a support wheel group 825 and a second guide wheel group 826 are installed on the roller mounting seat 824. The support wheel group 825 is slidably assembled with a roller support plate 827 connected to the X-axis translation mechanism. The roller support plate 827 can be connected to the X-axis slider fixing plate 814. When the support wheel group 825 slides along the roller support plate 827, the second guide wheel group 826 is used to guide the sliding of the support wheel group 825.

[0089] like Figures 13 to 15 As shown, in an exemplary embodiment, the support wheel group 825 and the second guide wheel group 826 each include at least one roller, the axis of the roller of the support wheel group 825 is horizontally arranged and parallel to the X direction, and the axis of the roller of the second guide wheel group is vertically arranged. In this embodiment, the number of rollers of the support wheel group 825 is 3, which are spaced apart along the Y direction, and the number of rollers of the second guide wheel group 826 is 2, which are spaced apart along the Y direction. With this structural design, the structure layout is compact, the space occupied is small, the assembly gap is easy to adjust, the self-adaptability is strong, the operation is stable, and the assembly difficulty is reduced.

[0090] like Fig.15 As shown, in an exemplary embodiment, each roller of the supporting wheel group 825 and the second guide wheel group 826 can be a polyurethane wheel, a PU rubber-coated wheel or other rollers with flexible surfaces, which is helpful to reduce movement noise and improve the adaptability and comfort of the fit.

[0091] like Figures 13 to 15 As shown, in an exemplary embodiment, the transfer bed 1 also includes an X-direction buffer limit block 831 for buffering the movement of the X-direction translation mechanism and a Y-direction buffer limit block 832 for buffering the movement of the Y-direction translation mechanism, so that the translation of the bed body is within the travel range of the X-direction and the Y-direction, avoiding excessive movement stroke and potential safety hazards. When the X-direction translation mechanism and the Y-direction translation mechanism of the same group of translation devices are both linear guide pairs, the X-direction buffer limit block 831 and the Y-direction buffer limit block 832 can both be installed on the Y-direction guide mounting plate 823; when the X-direction translation mechanism of the same group of translation devices is a linear guide pair and the Y-direction translation mechanism is a track wheel group, the X-direction buffer limit block 831 can be installed on the roller mounting seat, and the Y-direction buffer limit block 832 can be installed on the roller support plate.

[0092] like Figure 5 , Figures 13 to 16As shown, in an exemplary embodiment, the number of bed locking mechanisms 84 is two groups, one group is used to control the unlocking and locking of the bed's X-direction translation, and the other group is used to control the unlocking and locking of the bed's Y-direction translation, and the unlocking and locking can be controlled independently. The bed locking mechanism 84 includes a cable 841, a lock pin fixing seat 842, and a rack 843 installed on the X-direction translation mechanism or the Y-direction translation mechanism. One end of the cable 841 is connected to a lock pin 844 for engaging with the rack 843 to lock or disengaging from the rack 843 to unlock. A limiting portion 8441 is provided on the lock pin 844, and the lock pin 844 is movably installed on the lock pin fixing seat 842 and can move linearly on the lock pin fixing seat 842. The lock pin 844 is provided with a return spring 845, and the two ends of the return spring 845 respectively support the limit portion 8441 and the lock pin fixing seat 842. When the cable 841 pulls the lock pin 844 to disengage the rack 843 and unlock, the return spring 845 is in a compressed state. When the cable 841 is released, the return spring 845 drives the lock pin 844 to reset and engage with the rack 843 and lock. Among them, a pull ring 847 is provided at one end of the cable 841 away from the lock pin, and the cable 841 is covered with a cable outer tube 846. The two ends of the cable outer tube 846 are respectively fixed on the pull ring mounting seat 848 and the cable head fixing frame 849. The pull ring mounting seat 848 is fixedly connected to the lock pin fixing seat 842, and the lock pin fixing seat 842 can be used to connect with the bed body 12 or the X-guide rail mounting plate 813. The cable outer tube 846 is used to wrap the exposed cable 841 to protect the cable 841 . Meanwhile, the matching clearance between the locking pin 844 and the rack 843 and the strength of the return spring 845 can be adjusted by adjusting the length of the cable outer tube 846 . Among them, the two ends of the cable outer tube 846 can be adjusted by the wire bolts to adjust the effective length of the cable outer tube 846 between the pull ring mounting seat 848 and the cable head fixing frame 849, so as to adjust the fitting clearance between the locking pin 844 and the rack 843 and the strength of the reset spring 845. For example, when the effective length of the cable outer tube 846 is longer, the cable 841 is forced to be pulled out. When the cable 841 is pulled out to a certain extent, the reset spring 845 is compressed and the elastic force becomes larger, making it more difficult to pull out the pull ring 847 and the fitting clearance becomes larger. When the cable outer tube 846 is adjusted to the appropriate length, the reset spring 845 is just fully extended, the locking pin 844 is tightly fitted with the rack 843, and the pull ring 847 has no spare travel. At this time, the bed locking mechanism reaches the most ideal state. The pull ring 847 is located outside the pull ring mounting seat 848. The pull ring mounting seat 848 is provided with a locking groove. When the pull ring is pulled out, the rotating pull ring is stuck with the locking groove, and the cable remains stationary, so that the lock pin remains unlocked. The pull ring mounting seat 848 and the digital display screen 851 can be centrally arranged on the edge of the bed body for centralized operation and observation.In this embodiment, the rack of the bed locking mechanism for controlling the unlocking and locking of the X-direction translation of the bed is installed on the X-direction slider fixing plate 814, and the locking pin fixing seat is installed on the X-direction guide rail mounting plate 813; the rack of the bed locking mechanism for controlling the unlocking and locking of the Y-direction translation of the bed is installed on the Y-direction guide rail mounting plate 823, and the locking pin fixing seat is installed on the Y-direction slider fixing plate or directly connected to the bottom of the bed. The unlocking and locking operations are simple and convenient, and can be locked or unlocked at any position within the moving range, with strong versatility.

[0093] like Figure 5 , Figure 13 to Figure 14 As shown, in an exemplary embodiment, the transfer bed also includes a metering device, which includes a grating ruler 852 and a digital display screen 851. The grating ruler 852 is used to measure the translation amount of the bed body 12, and the translation amount of the bed body 12 is displayed through the digital display screen 851. The metering device can be set in two groups, one for measuring and displaying the translation in the X direction and the other for measuring and displaying the translation in the Y direction. The digital display screen 851 can be integrated and assembled to the surface of the bed body, so that the operator can observe the direction and distance of movement at any time, so as to accurately control the bed body and improve the safety of the equipment.

[0094] like Figures 1 to 17 As shown, the method for using the medical bed of the present invention is to complete the preparation for the patient's surgery on the transfer bed, transfer the patient who has completed the preparation for the surgery through the transfer bed, dock and lock the transfer bed with the treatment bed, treat the patient placed on the transfer bed through the treatment bed, and after the treatment is completed, unlock and separate the transfer bed from the treatment bed, and transfer the patient. When the transfer bed and the treatment bed are docked, they are guided by a guide mechanism; the transfer bed and the treatment bed are docked and locked by the transfer bed locking mechanism; after docking in place, the treatment hole set on the transfer bed is located above the treatment window set on the treatment bed, and the translation device on the transfer bed drives the bed body of the transfer bed to translate and fine-tune so that the treatment hole is aligned with the treatment window, and is locked by the bed body locking mechanism on the transfer bed; the patient on the transfer bed is treated on the treatment bed, and after the treatment is completed, the transfer bed locking mechanism is unlocked, the transfer bed is separated from the treatment bed, and the patient is transferred.

[0095] like Figures 1 to 17 As shown, in an exemplary embodiment,

[0096] During surgical preparation, the cushion 72 and the support plate 71 are placed on the bed 12 in sequence, and the positioning cushion 73 is placed on the support plate 71. The position of the auxiliary operation hole on the positioning cushion 73 is adjusted according to the position of the left or right side of the patient's body where the breast to be treated is located, and the auxiliary operation hole is facing the side to be treated (for example, if the patient's left breast is treated, the auxiliary operation hole should be facing the patient's left side). The patient lies flat on the cushion in a prone position, adjusts the body position, and completely places the breast to be treated into the positioning hole, and tries to make the center of the breast coincide with the center of the positioning hole 731. The arm to be treated is placed close to the body and flat toward the foot, and the arm on the non-treated side is naturally bent and flat toward the head; select a head pad 74 of appropriate thickness, and the patient's head is tilted to the side, facing the non-treated side. Place the foot pad 76 under the patient's ankle and adjust it to a suitable position so that the feet can relax naturally. Select an adjustment pad of corresponding specifications and place it under the non-treatment side of the patient's body. Adjust the position of the adjustment pad along the length direction of the bed board so that the breast on the non-treatment side is located in the second avoidance opening; adjust the position of the adjustment pad along the width direction of the bed board so that the patient's body is tilted at a certain angle so that the patient's body on the side to be treated is close to the cushion, and all parts of the body are naturally relaxed without obvious pressure. Install the sliders 773 at both ends of the fixing belt assembly 77 into the slide grooves 12 on the bed body 12 respectively, and slide the sliders to adjust the fixing belt assembly to a suitable position; adjust the tightness of the fixing belt assembly so that the patient's torso is stable and there is no obvious pressure on the back, and the patient is supported and fixed on the transfer bed. During the treatment process, the position of each component can be flexibly adjusted at any time according to the treatment needs to improve safety performance.

[0097] During docking, the transfer bed and the treatment bed are docked under the guidance of the guide mechanism. After docking, the transfer bed and the treatment bed are locked by the transfer bed locking mechanism, so that the transfer bed and the treatment bed remain relatively stable.

[0098] During treatment, if the bed is already in place and does not need to be translated, the bed locking mechanism will always remain locked to prevent the bed from sliding back and forth and causing safety accidents. If the bed needs to be slightly translated, pull the pull ring out of the pull ring mounting seat to set the distance and rotate it 90° counterclockwise to fix it with the locking groove. At this time, the pull ring drives the cable to disengage the locking pin from the rack, and the translation device is unlocked; after the movement is completed, disengage the pull ring from the locking groove and rotate it 90° clockwise to reset. The reset spring will push the locking pin to mesh with the rack again, and the translation device is locked to complete the translation adjustment.

[0099] After the treatment is completed, the locking mechanism of the transfer bed is unlocked, the transfer bed is separated from the treatment bed, and the transfer bed transfers the patient to the designated place.

[0100] The method for using the medical bed of the present invention is simple and convenient to operate, the patient does not need to be separated from the transfer bed during the entire process, and the transfer bed and the treatment bed have high docking positioning accuracy, which improves safety performance and treatment efficiency and reduces costs and labor intensity.

[0101] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
