Description

[0001] The claimed technical solution relates to the field of medical instrument making, namely to the structural elements (supporting systems) of devices, in particular those including a movable scanning unit, for example, bone densitometers, full-height X-ray tables and gamma cameras, and can combine the functions of a supporting frame for placing diagnostic equipment and a table for placing a patient.

[0002] A prior art solution is known that describes a mechanism for fastening a bed of digital radiography equipment, including a bed base and a bed frame mounted on the bed base, a roller unit is installed between the base and the frame, and the bed base and the frame are connected by rolling through the roller unit (China Patent No. CN 219289486 U, IPC A61B 6 / 00, A61B 6 / 04, published 04.07.2023).

[0003] The prior art also includes a solution, selected as the closest prior art, describing an X-ray apparatus comprising a power supply, a cabinet, a stand with a rotating arm, an emitter, a filter, a collimation device, and a diagnostic table. The apparatus includes an additional filter, movably mounted on the emitter or collimation device and formed as a single plate or a set of plates, a removable cradle for placing the child and having a device on the bottom for securing the X-ray cassette with the ability to secure it anywhere on the cradle's bottom, a device for restricting the child's movement, and a recess for the child's head.The device for moving and securing the cradle is designed with the possibility of securing it to a diagnostic table and consists of a base, a movable carriage, guides and a handle for fixing the cradle in a given position, wherein the carriage is provided with guide grooves for transverse movement of the cradle together with the carriage and grooves for guides for longitudinal movement of the cradle (Patent of the Russian Federation No. RU 2150888 C1, IPC A61B 6 / 04, published 20.06.2000).

[0004] The claimed technical solution differs from existing solutions in that the frame design allows for connection to medical device components, rather than simply supporting the patient, allowing for a significant reduction in the device's overall dimensions. Furthermore, the special design of the upper and lower frames allows for easy installation and repair of the medical device components, as well as the ability for the movable scanning unit to move relative to the frame, rather than vice versa, in cases where the scanning unit is stationary and the patient is moving relative to it.

[0005] The objective of the declared technical solution is to create a reliable frame for a medical device with a movable scanning unit, ensuring ease of installation, maintenance, and use as part of a medical device.

[0006] The technical result of the claimed solution is high technological efficiency and reliability of the solution.

[0007] Increased technological efficiency is achieved, in particular, by the ease of installation and maintenance of the frame and elements of the medical device, as well as high mobility and ease of use.

[0008] Increased reliability is achieved, in particular, by high rigidity, strength and durability of the structure, as well as high load-bearing capacity of the frame.

[0009] The claimed technical result is achieved due to the fact that the frame of the medical device with a movable scanning unit consists of a rectangular upper frame and a rectangular lower frame connected to each other to form side walls of the frame, wherein the upper frame is made of connected beams and includes elements for connection with elements of the medical device and corner posts connected to the beams and containing elements for connection with the lower frame, the lower frame is made of profiled sheet parts including shelves mated at an angle to each other, includes corner posts for connection with the corner posts of the upper frame and is connected to wheel supports with wheels fixed to them for moving the medical device, wherein one of the side walls of the frame includes an opening for the possibility of moving the movable scanning unit of the medical device, formed by a panel attached to the corner posts of the lower frame, and a panel,made in one piece with the corner posts of the upper frame of this side wall in the form of a profiled panel, and the upper frame includes a guide for moving the movable scanning unit of the medical device along it.

[0010] The claimed technical solution is a frame for a medical device with a movable scanning unit, such as a bone densitometer, a full-height X-ray table, or a gamma camera. The frame can serve as a supporting structure for the medical device components, and a table base can be mounted on the frame to accommodate the patient's body.

[0011] The frame consists of a rectangular upper frame and a rectangular lower frame connected to form the frame's side walls. This design allows for simple and quick mounting of medical device components on different parts of the frame, specifically the upper and lower frames, and then the connection of the two frames to form a single unit, making the proposed solution highly technological. Furthermore, this design also allows the upper frame to be detached from the lower frame, if necessary, for panoramic access to the internal equipment for servicing, thereby further enhancing the solution's technological effectiveness. Furthermore, the rectangular frames and their connection to form the frame's side walls create a single, rigid structure with high load-bearing capacity for supporting medical device components and the patient's body, ensuring the solution's high reliability.In a preferred embodiment, the upper and lower frames are connected by bolts, which is a simple, detachable connection that further simplifies the assembly and disassembly process. In other specific embodiments, the upper and lower frames can be connected using various locking joints known in the art, or tongue and groove joints.

[0012] The upper frame is constructed of interconnected beams and includes elements for connection to medical equipment components and corner posts connected to the beams and containing elements for connection to the lower frame. The upper frame's construction from interconnected beams ensures the structural integrity and load-bearing capacity necessary to support the medical equipment components and absorb and transfer the patient's body load to the lower frame. The inclusion of elements for connection to medical equipment components in the upper frame lends reliability and manufacturability to the frame, as it allows for simple installation of these components without the need for separate structures and fastening systems that increase the frame load and create vulnerable connection points. The medical equipment components can be secured using any known method, such as threaded connections, hanging, etc.The presence of corner posts connected to the beams allows the upper and lower frames to be spaced apart, increasing the frame's internal space to accommodate more medical equipment components. The corner posts also transfer the load from the upper frame to the lower frame's most rigid and durable component, specifically the corner of the rectangular frame formed by the connected profiled sheet metal parts, further enhancing the structural reliability. In the context of the proposed solution, the term "corner posts" refers to posts located at the corners of the rectangular frame.The corner posts also contain elements for connecting to the lower frame. Unlike, for example, a welded connection, this allows for a detachable connection between the upper and lower frames, allowing for quick and easy installation of medical device components. This also allows for simple maintenance of these components without the use of cutting tools, thereby significantly increasing the manufacturability and durability of the solution. The upper frame beams are preferably made of profiled rectangular tubing, which further increases the upper frame's rigidity due to its profiling and the presence of stiffening ribs while maintaining a low weight. Unlike, for example, cast rod-shaped structures, this also allows for the patient's body weight to be supported, further reducing the weight of the structure itself, further enhancing the reliability of the solution, and simplifying the transportation of the medical device.However, in other preferred embodiments, the frame beams may be constructed from cast rod-shaped elements, profiled sheet metal parts, and other elements that can be joined together to form a frame. In specific embodiments of the claimed solution, the elements for connecting to the medical device components are profiled panels connected to the beams. This further increases the rigidity of the upper frame and its area, thereby further distributing pressure from the patient's body to the frame, as well as from the medical device components connected by the upper frame. Such profiled panels may also include various openings and fasteners for connecting to the medical device components. They may also be lightweight, in particular by incorporating openings, which further increases their rigidity while reducing weight, thereby further enhancing the manufacturability and reliability of the solution.In other particular embodiments, the elements for connecting to the elements of the medical apparatus may be various fastening elements, openings and other auxiliary parts connected and / or made in the beams of the upper frame and / or corner posts.

[0013] The lower frame is constructed from profiled sheet metal parts, including shelves connected at an angle to each other, providing high rigidity and strength and, consequently, significantly increasing the load-bearing capacity of the frame. In the context of this solution, the term "profile sheet metal parts" refers to curved parts made from a sheet of material (e.g., metal or composite material), in particular with shelves connected at an angle to each other. Furthermore, the use of profiled sheet metal parts allows for the lower frame to retain its rigidity while reducing its weight, which also simplifies transportation of the medical device and improves its manufacturability. In various embodiments of the claimed solution, the profiled sheet metal parts of the lower frame can be connected with fasteners or by welding, which is preferable due to the strength and rigidity of the connection.The shelves of the profiled sheet metal parts are preferably joined at right angles to each other, which further increases the load-bearing capacity of the lower frame and allows for the formation of the side walls and bottom of the frame, further simplifying the installation of medical device components within the frame, using these shelves as supports and by overlapping the components. In certain embodiments, the shelves of the profiled corner parts may include openings for accommodating a power connector and other medical device components, as well as for replacement and servicing of these components. In certain embodiments, the lower frame may also include elements for connecting to medical device components, further simplifying its installation.

[0014] The lower frame includes corner posts for connection to the corner posts of the upper frame, which allows the load-bearing force from the upper frame to be transferred to the most rigid and durable section of the lower frame, namely the corner of the rectangular frame, thereby imparting high durability to the frame. In specific embodiments of the claimed solution, the corner posts of the upper frame are angles, which imparts additional rigidity and, consequently, the load-bearing capacity of the entire frame. In a specific embodiment, the corner posts of the lower frame can also be angles, which further increases their rigidity. They can also be integrally formed with the opposite profiled sheet parts of the lower frame, i.e., two corner posts are integrally formed with one profiled sheet part of the lower frame, and the other two corner posts are integrally formed with another profiled sheet part located on the opposite side of the rectangular lower frame.This particular embodiment further simplifies installation, as the posts are already connected to the frame components. This particular post configuration further improves the predictability and uniformity of load distribution across the lower frame, further reducing the load on the connection points with the remaining two profiled sheet metal parts of the lower frame. In this preferred embodiment of the claimed solution (with the design and configuration of the corner posts described above), the elements connecting to the lower frame can be angles containing inclined elements for connecting the upper and lower frames to each other and including openings and fixing elements for the connecting elements connecting the upper and lower frames, which further enhances the reliability and manufacturability of the claimed solution.In a specific embodiment, implementing these elements as corners further simplifies joining two frames with corner posts, which in a specific embodiment are also designed as corner posts, while also increasing the rigidity of these elements. The presence of inclined elements further simplifies the installation and mating of the corner posts of two frames with precise dimensional tolerances due to the ability of the lower frame corner to slide along the inclined planes of the element until it contacts the upper frame corner and fully connects, i.e., the upper frame "inserts" into the lower frame with the corner posts inside each other. These elements for connecting to the lower frame also include openings and locking elements for connecting the upper and lower frames, further simplifying frame assembly without the need for separate locking elements.In other specific embodiments of the claimed solution, the elements connecting the upper frame to the lower frame may be any known locking joints, including, for example, tongue-and-groove joints. In one preferred embodiment, the locking element is a nut, allowing for a simple bolted connection between the frames. The nut can be welded to the connecting element.

[0015] The lower frame is connected to casters with wheels attached to them for moving the medical device. This increases the mobility of the medical device and allows for its easy movement even with a patient on it due to its high load-bearing capacity, thereby imparting a high-tech solution. The casters with wheels attached to them are preferably connected to the lower frame in a swivel manner, i.e., they are self-rotating, further simplifying the movement of the medical device in various directions without the need to rotate the entire device, thereby further enhancing its technological effectiveness. The casters with wheels attached to them preferably include a locking system to secure the position of the medical device, further simplifying the operation of the medical device by allowing the wheels to be locked and preventing possible movement during operation.

[0016] One of the side walls of the frame includes an opening for the movement of the movable scanning unit of the medical device. This opening is formed by a panel attached to the corner posts of the lower frame and a panel integral with the corner posts of the upper frame of this side wall in the form of a profiled panel. This opening allows the movable scanning unit to move relative to the frame of the medical device and the patient's body positioned thereon. This ensures high reliability and ease of use of the solution, since, unlike prior art solutions, movement of the patient's body relative to the scanning unit is more difficult due to the high mass and load on the movable parts.A panel attached to the corner posts of the lower frame and forming an opening provides additional protection for the medical device components, located primarily within the frame, from mechanical damage, while also allowing access for servicing, if necessary, providing a solution that combines high reliability and high manufacturability. Furthermore, the panel, which is integral with the corner posts of the upper frame of this side wall and forms a profiled panel and also forms an opening for the movement of the medical device's movable scanning unit, increases the rigidity of the upper frame and further protects the medical device components from mechanical damage.The upper frame, as noted above, features a side wall with an opening for the sliding scanning unit. It also includes a guide for the medical device's sliding scanning unit. This allows the medical device to fulfill its intended purpose without the need for additional structures or supports for the sliding scanning unit, keeping everything within the single structure of the medical device. This also reduces its dimensions, simplifies movement and use, and ultimately lends the solution a high level of technological advancement. The guide is preferably made of a profiled rectangular tube, which further enhances its rigidity with the addition of stiffening ribs. The tube's cavity allows for the placement of components for the sliding scanning unit's movement.In other specific embodiments of the claimed solution, the guide can be made of a U-shaped profile, which also allows the movable scanning unit to move along it. The guide preferably includes elements for stabilizing the movement of the movable scanning unit, in particular, locking pins. A prior art embodiment of the movable scanning unit can include a drive belt, which ensures the unit's linear movement, and a tensioning mechanism. This mechanism, in particular, interacts with these guide elements to create an expanding force that displaces the tension block, thereby eliminating play and compensating for operational belt stretch. This further enhances the durability and reliability of the entire medical device, as well as its manufacturability, since it does not require additional mechanisms to compensate for drive belt stretch.In various versions of the claimed solution, the guide may be a separate part connected to the beams of the upper frame, or it may be one of the beams and participate in the formation of the upper frame of the frame.

[0041] Next, one of the preferred embodiments of the claimed technical solution is described with reference to the figures.

[0042] The frame of a medical apparatus with a movable scanning unit consists of a rectangular upper frame (1) and a rectangular lower frame (2) connected to each other, preferably by a bolted connection, to form the side walls of the frame.

[0043] The upper frame (1) is made of connected beams (3) and includes elements (4) for connection with elements of the medical apparatus and corner posts (5) connected to the beams (3) and containing elements (6) for connection with the lower frame (2). The elements (4) for connection with elements of the medical apparatus are preferably profiled panels connected to the beams (3).

[0044] The upper frame (1) includes a guide (7) for moving a movable scanning unit of the medical apparatus along it, preferably made from a profiled rectangular pipe and including elements (8) for stabilizing the movement of the movable scanning unit.

[0045] The lower frame (2) is made of profiled sheet parts (9), including shelves (10) connected at an angle to each other, preferably right angles, includes corner posts (11) for connection with the corner posts (5) of the upper frame (1) and is connected to wheel supports (12) with wheels (13) fixed to them, preferably self-rotating, for moving the medical apparatus.

[0046] One of the side walls of the frame (see Fig. 3) includes an opening (14) for the possibility of moving the movable scanning unit of the medical apparatus, formed by a panel (15) attached to the corner posts (11) of the lower frame (2), and a panel (16) made in one piece with the corner posts (5) of the upper frame (1) of this side wall in the form of a profiled panel.

[0047] The beams (3) of the upper frame (1) are preferably made of a profiled rectangular tube, and the corner posts (5) of the upper frame (1) are preferably angles. The corner posts (11) of the lower frame (2) are also preferably angles and are made integral with the opposite profiled sheet parts (9) of the lower frame (2) (see Fig. 6).

[0048] The elements (6) for connection with the lower frame (2) are corners containing inclined elements (17) for connecting the upper (1) and lower (2) frames with each other and including openings (18) and fixing elements (19), preferably nuts, for connecting elements of the connection of the upper (1) and lower (2) frames (see Fig. 7, 8).

[0049] The claimed frame for a medical apparatus with a movable scanning unit can be used as follows.

[0050] The upper frame (1) and lower frame (2) are connected directly at the factory after the internal components—elements of the medical device—are installed, access to which will be restricted after joining. These elements are installed using any known method, using elements (4) for connecting to the medical device elements.

[0051] The upper (1) and lower frames (2) are joined by means of elements (6), which, due to their inclined elements (17), allow one frame to be inserted into the other, connecting them with corner posts (5 and 11). A connecting element of the bolted connection is inserted into the holes (18) of the elements (6) and secured with a nut (19) (the corner posts (11) of the lower frame, obviously, contain corresponding holes for the connection).

[0052] On one of the side walls (see Fig. 3), a panel (15) is mounted by attaching it to the corner posts (11) and, together with the panel (16), an opening (14) is formed, which, together with the guide (7), is used for mounting the movable scanning unit of the medical apparatus.

[0053] When using the medical device incorporating the claimed frame, the patient lies supine on a platform mounted on top of the upper frame (1), which functions as a loaded truss. Through the connection between the upper (1) and lower (2) frames, the load is transferred to the lower frame (2), which redistributes the point loads from the corner posts (5) of the upper frame over a wide area of ​​the wheelbase.

[0054] During scanning, the scanning unit moves linearly along the longitudinal axis of the device. The frame ensures geometric stability of the trajectory relative to the patient. The frame's rigid design compensates for vibrations caused by the shift in the center of mass. The beams (3) of the upper frame (1) ensure minimal deflection under the weight of the moving scanning unit and the patient's body, maintaining the linearity of the scanning trajectory.

[0055] The frame boasts high strength-to-weight ratios. Assembly is further simplified by the special shape of the upper frame (1) elements (6), which allows for automatic positioning of the frames relative to each other, further reducing installation labor.

[0056] The ability to separate the frame into two units (upper (1) and lower (2) frames) provides panoramic access to the internal equipment (power supplies, drives) for servicing. Connecting the upper (1) and lower (2) frames allows (if major repairs or replacement of a large component are required) the device to be separated into two units without the use of cutting tools. The proposed technical solution can be used as a frame for a medical device with a movable scanning unit and is characterized by high reliability and manufacturability.

[0057] The presented figures, description of the design, and use of the frame of the medical device with a movable scanning unit do not exhaust the possible design options or in any way limit the scope of the claimed technical solution. Other design options are possible within the scope of the claimed formula.
