Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a medical bed for auxiliary treatment. Background Art

[0002] Focused ultrasound therapy is a new type of tumor treatment method. When using this method to treat tumors, ultrasound positioning can be used to kill tumor cells in the target area with high-intensity ultrasound without damaging surrounding normal tissues, thus achieving non-invasive treatment of tumor tissues.

[0003] During focused ultrasound therapy, a medical bed that can be raised and lowered and can move horizontally is required for auxiliary treatment. The medical bed uses its lifting function to facilitate patients getting on and off the bed, and uses its horizontal reciprocating motion to achieve the purpose of auxiliary positioning.

[0004] At present, the lifting and driving mechanism of the existing medical bed for focused ultrasound therapy is a forklift structure, and the movable plate and fixed plate used to support the bed are complex stainless steel welded structures. Since the lifting and driving force point is far away from the center of gravity of the medical bed, the driving mechanism and guide mechanism of the medical bed are very heavy, and the overall structure of the medical bed is also very large, resulting in high costs, and the manufacture, assembly, transportation and on-site installation of the medical bed are inconvenient.

[0005] In addition, although the existing medical equipment technology also provides some medical beds for auxiliary examination, for example, the patent application document with publication number CN108618898A discloses a medical bed for auxiliary examination, and its lifting device includes a telescopic rod with one end mounted on a base and the other end mounted on a load-bearing platform, and a second power mechanism for providing power to the telescopic rod. The lifting device also includes two cross-placed lifting rods, the top ends of the lifting rods are fixed on the load-bearing platform, and the bottom ends of the lifting rods are slidably mounted on the base. Therefore, during the lifting process of the load-bearing platform, the two cross-placed lifting rods can provide good support for the load-bearing platform, ensuring the smooth operation of the lifting process of the load-bearing platform. However, this cross-sliding lifting method, on the one hand, increases the complexity of assembly, and on the other hand, in order to ensure the smooth operation of sliding and cross-lifting, the maintenance cost of the equipment in the later stage increases. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a medical bed for auxiliary treatment to solve the problems of the existing medical bed for focused ultrasound treatment, such as the large overall size, heavy weight, inconvenience in assembly, transportation, on-site installation and high cost.

[0007] To achieve the above-mentioned and related purposes, the utility model provides a medical bed for auxiliary treatment, comprising a base, a bed board assembly and a lifting mechanism, wherein the lifting mechanism is used to connect the base and the bed board assembly and drive the bed board assembly to be lifted and lowered;

[0008] The lifting mechanism includes at least three lifting members, which are axially symmetrically distributed around the center of gravity of the medical bed;

[0009] The bed board assembly includes a bed board support frame, which includes a plurality of corner aluminums and forms a frame structure through the plurality of corner aluminums. Among them, at least one corner aluminum is used to provide a horizontal sliding track.

[0010] Furthermore, the lifting member is a lift.

[0011] Furthermore, the lifting members are a lift and a lifting guide post.

[0012] Furthermore, the plurality of corner aluminums include a first corner aluminum and a second corner aluminum. The second corner aluminum is arranged in the first corner aluminum. The first corner aluminum is used to provide a horizontal sliding track, and the second corner aluminum is used to provide a mounting position.

[0013] Furthermore, the bed board assembly further includes a mounting plate, and the mounting plate is mounted in the bed board support frame through the second corner aluminum.

[0014] Furthermore, the lifting mechanism further includes a plurality of supports, and the lifting members are mounted on the mounting plate through the supports.

[0015] Furthermore, the bed board assembly further includes a plurality of sliders, and the sliders are slidably mounted in the second corner aluminum.

[0016] Furthermore, the bed board assembly further includes a translation drive mechanism, and the translation drive mechanism is mounted on the corner aluminum.

[0017] Furthermore, the lifting mechanism further includes a guide sleeve, and the lifting guide post is mounted in the guide sleeve.

[0018] Furthermore, the lifting mechanism further includes a mounting cylinder, and the mounting cylinder is mounted on the base, and the mounting cylinder is used to mount the guide sleeve.

[0019] The beneficial technical effects of the present utility model are as follows:

[0020] The lifting mechanism of the medical bed in this application is arranged around the center of gravity of the medical bed. On the premise of ensuring the load capacity of the medical bed, the guiding load is reduced and the eccentric load weight is reduced. In this way, the size specifications of the lifting members can be reduced, and the weight and manufacturing cost can be significantly reduced.

[0021] This application improves the fixed plate and the moving plate of the bed body translation mechanism of the existing medical bed from a stainless steel welded steel frame structure to a corner aluminum assembly structure, reducing the complexity of the structure, reducing the cost, and at the same time reducing the weight.

[0032] As Figure 1 shown, the present utility model provides a medical bed for adjuvant therapy, which includes a base 13, a bed board assembly, and a lifting mechanism. The lifting mechanism is used to connect the base 13 and the bed board assembly and drive the bed board assembly to lift and lower.

[0033] The lifting mechanism includes at least three lifting members, which are axially symmetrically distributed with the center of gravity of the medical bed as the center.

[0034] The bed board assembly includes a bed board support frame 9. The bed board support frame 9 includes a plurality of angle aluminums and forms a frame structure through the plurality of angle aluminums. Among them, at least one angle aluminum is used to provide a horizontal sliding track.

[0035] In some embodiments, compared with the existing treatment bed whose lifting drive device is composed of three offset guiding structures, the lifting mechanism of the present application is arranged around the center of gravity of the medical bed. On the premise of ensuring the load capacity of the medical bed, the guiding load is reduced and the offset load weight is reduced. In this way, the size specifications of the lifting members can be reduced, and the weight and manufacturing cost can be significantly reduced.

[0036] In some embodiments, the lifting member of the present application is a lift 10, or the lifting member is a lift 10 and a lifting guide post 3. Further, the lift 10 of the present application is a screw lift. The combination forms of the lifting members of the present application include but are not limited to one lift 10 paired with three lifting guide posts 3. The three lifting guide posts 3 are triangularly distributed with the center of gravity of the medical bed as the center, and the lift 10 is installed between two lifting guide posts 3 on the same side; one lift 10 paired with four lifting guide posts 3; three lifts 10 are triangularly distributed with the center of gravity of the medical bed as the center; four lifts 10 are synchronously lifted. Among them, the combination of one lift 10 paired with three lifting guide posts 3 in the present application is applicable to the mechanism with offset jacking when the center of gravity range is occupied by necessary mechanisms, such as a focused ultrasound treatment system.

[0037] In some embodiments, the present application changes the fixed plate and the moving plate of the existing translation mechanism of the treatment bed from a stainless-steel welded steel frame structure to an angle-aluminum assembly structure. The frame structure of the bed board support frame 9 composed of angle aluminum in the present application provides rigid support for the bed board. The shape accuracy and its own rigidity of the angle aluminum itself meet the use requirements, thus effectively reducing the overall weight and process cost of the medical bed, reducing the difficulties of transportation, installation and maintenance, and improving the acceptance of users.

[0038] In some embodiments, such as Figure 1 and Figure 2 shown, multiple angle aluminums in the present application include a first angle aluminum 7 and a second angle aluminum 8. The second angle aluminum 8 is arranged in the first angle aluminum 7. The first angle aluminum 7 is used to provide a horizontal sliding track, and the second angle aluminum 8 is used to provide a mounting position. Further, two guide rails 5 for horizontal movement are installed in the first angle aluminum 7.

[0039] In some embodiments, the bed board assembly further includes a mounting plate 12, and the mounting plate 12 is installed in the bed board support frame 9 through the second angle aluminum 8. The present application does not limit the specific structure of the mounting plate 12, and it can be designed according to actual needs.

[0040] In some embodiments, the lifting mechanism further includes multiple supports 4, and the lifting member is installed on the mounting plate 12 through the supports 4. Further, the support 4 in the present application is preferably used to install the lifting guide post 3, and the connection manner between the support 4 and the mounting plate 12 includes but is not limited to fixed connection manners such as screw connection. The connection manner between the support 4 and the lifting member is also a fixed connection, so that the lifting member, the support 4 and the mounting plate 12 can realize synchronous lifting movement.

[0041] In some embodiments, such as Figure 2 shown, the bed board assembly further includes multiple sliders 6, and the sliders 6 are slidably installed in the second angle aluminum 8. The present application uses the sliders 6 to realize the horizontal movement of the bed board and the bed board support frame 9. Further, three sliders 6 are preferably installed on each second angle aluminum 8.

[0042] In some embodiments, the bed board assembly further includes a translation drive mechanism 11, and the translation drive mechanism 11 is installed on the angle aluminum. The translation drive mechanism 11 in the present application can be a speed reduction motor, a gear and a rack structure. At this time, the gear and the rack are respectively installed on the second angle aluminum 8 and the first angle aluminum 7. Or, the gear and rack structure in the present application can be replaced by a synchronous belt structure or an electric cylinder.

[0043] In some embodiments, the lifting mechanism of the present application further includes a guide sleeve 2, and the lifting guide post 3 is installed in the guide sleeve 2. The lifting mechanism further includes a mounting cylinder 1, and the mounting cylinder 1 is installed on the base 13, and the mounting cylinder 1 is used to install the guide sleeve 2.

[0044] In some embodiments, taking the lifting mechanism composed of a screw jack and three lifting guide columns 3 as an example, when the medical bed of the present application is in use, the base 13 plays a supporting role. Driven by the screw jack for lifting drive, the three lifting guide columns 3, together with the support 4 and the mounting plate 12, move up and down synchronously, thereby driving the bed board on the bed board support frame 9 and the user to move up and down synchronously, which is convenient for the user to get on and off the bed. When it is necessary to position the treatment part of the user, driven by the reduction motor, it slides and translates along the guide rail 5 to realize the left and right reciprocating movement of the bed board support frame 9 and the bed board.

[0045] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
