[0032] In order to more clearly illustrate the technical solutions in the embodiments of the present application or in the related art, the following will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0033] Interventional diagnosis and treatment technology has been widely applied in clinical practice. As an important component in interventional diagnosis and treatment technology, the catheter bed is of great importance in clinical application of the technology. Therefore, how to improve the performance of the catheter bed directly affects the application and development of the interventional diagnosis and treatment technology. In addition, the catheter bed is used more in clinical practice, mainly for supporting patients lying on the bed surface plate. Therefore, the connection strength between the bed surface plate and the support part of the bed body needs to be ensured. In the related art, the bed surface plate and the support part of the catheter bed are usually connected by screws. After the patient lies on the bed surface plate, the stress position of the bed surface plate and the support part is only near the connecting screw, and the stress area is very small, which will cause large local deformation of the bed surface plate and the support part and poor structural strength.

[0034] In view of the above, in a first aspect, referring to Figures 1-2 The application provides a catheter bed 1, comprising a base 10, a bed plate 20 and a support rail 30, the base 10 provides a mounting base and a setting space for the bed plate 20 and the support rail 30, and the catheter bed 1 can be placed on the bottom surface or the bearing platform through the base 10.

[0035] As shown in Figures 3-4 The bed plate 20 is located above the base 10, the bottom surface of the bed plate 20 comprises a main plate surface 211 and an arc-shaped transition surface 221 connected to the edge of the main plate surface 211, and the arc-shaped transition surface 221 extends in a curved manner towards the base 10; the lower side of the bed plate 20 is provided with the support rail 30, the support rail 30 is in sliding connection with the base 10, and the upper side of the support rail 30 is fixedly connected with the main plate surface 211 and the arc-shaped transition surface 221.

[0036] Specifically, the bed plate 20 can slide relative to the base 10, so that the bed plate 20 can be flexibly adjusted in position according to the diagnosis and treatment requirements, improving the convenience of operation, at the same time, the setting of the support rail 30 not only enhances the carrying capacity of the bed plate 20, but also ensures the stability of the bed plate 20 during movement, and the upper side of the support rail 30 is fixedly connected with the main plate surface 211 and the arc-shaped transition surface 221, thereby increasing the contact area between the bed plate 20 and the support rail 30, reducing the local deformation, thereby facilitating to improve the connection strength between the bed plate 20 and the support rail 30, and also making it possible to improve the stability of the bed plate 20. Through the cooperative action of the bed plate 20 and the support rail 30, the catheter bed 1 not only can effectively bear the weight of the patient, but also can keep stable during movement. The bed plate 20 can be made of carbon fiber material, so that the mass of the bed plate 20 is lighter and the strength is larger, and the support rail 30 can be made of high-strength alloy material, so as to improve its durability and carrying capacity.

[0037] It should be noted that the upper side of the support rail 30 is closely connected with the main plate surface 211 and the arc-shaped transition surface 221, and is fixedly connected, so as to increase the contact area between the bed plate 20 and the support rail 30, disperse the stress between the bed plate 20 and the support rail 30, reduce the stress concentration point, thereby helping to reduce the possibility of local deformation, ensuring that the connection between the bed plate 20 and the support rail 30 is more firm and reliable, and effectively improving the connection strength and stability between the bed plate 20 and the support rail 30.

[0038] The upper surface of the bed plate 20 is used for the patient to lie flat, and thus the upper surface of the bed plate 20 can be flat, and only the edge of the main plate surface 211 on the lower side of the bed plate 20 is provided with an arc-shaped transition surface 221. Alternatively, in some embodiments, the bed plate 20 comprises a main plate 21 and a transition portion 22, the transition portion 22 extends in an arc shape as a whole, one end of the transition portion 22 is connected with the edge of the main plate 21, and the other end of the transition portion 22 extends in a curved manner towards the direction of the base 10, and thus the bottom surface of the main plate 21 is the main plate surface 211, and the inner surface of the transition portion 22 is the arc-shaped transition surface 221. It can be understood that, compared with the bed plate with a straight edge, the design of the transition portion 22 in the present embodiment can increase the contact range of the edge of the bed plate 20, effectively disperses the contact pressure, reduces the friction, and thus can reduce the discomfort of the patient when contacting the edge of the bed plate 20, reduces the knocking of the edge of the bed plate 20 on the patient, and improves the use comfort of the patient. The main plate 21 and the transition portion 22 can be integrally formed.

[0039] In some embodiments, the bottom of the base 10 can also be provided with walking wheels, so that the catheter bed 1 can be more flexible in moving and positioning during use. In order to ensure that the catheter bed 1 can be stably fixed at a specific position when needed, the walking wheels can also be provided with a locking device. When it is necessary to fix the catheter bed, the walking wheels can be locked by the locking device to prevent unnecessary movement of the catheter bed 1 during use, thereby ensuring the safety and accuracy of the operation.

[0040] In some embodiments of the present application, as shown in Figure 1 The catheter bed 1 further comprises a movable assembly 50, which is arranged between the bed plate 20 and the base 10 and connected with the bed plate 20 and the base 10, and can be used to drive the bed plate 20 to move relative to the base 10.

[0041] For example, the movable assembly 50 can realize the functions of lifting and adjusting the left and right angles of the bed plate 20. The movable assembly 50 comprises a driving mechanism and a transmission mechanism. The fixed structure in the transmission mechanism is connected with the base 10, and the movable structure in the transmission mechanism is connected with the bed plate 20. The driving mechanism drives the transmission mechanism, so that the movable structure in the transmission mechanism drives the bed plate 20 to move, thereby improving the use convenience and comfort of the bed plate 20.

[0042] In some embodiments of the present application, the orthographic projection of the bed plate 20 on the horizontal plane covers the orthographic projection of the support rail 30 on the horizontal plane, so that the support rail 30 is completely located below the bed plate 20, avoiding the partial structure of the support rail 30 protruding from the edge of the bed plate 20, thereby preventing the edge of the support rail 30 from knocking the patient or medical staff during use, and improving the safety of use.

[0043] In some embodiments of the present application, as shown in Figures 2-3 The edge of the peripheral side of the main plate surface 211 is provided with an arc-shaped transition surface 221, that is, the transition portion 22 is arranged on the peripheral side of the main plate 21, so that the edge of the peripheral side of the main plate 21 is smoother, further reducing the discomfort of the patient when directly contacting the edge of the bed plate 20, and also reducing the wear of the edge of the bed plate 20.

[0044] Alternatively, in some embodiments, as shown in Figure 3 The main plate 21 of the bed plate 20 includes a first portion 212 and a second portion 213, the first portion 212 of the main plate 21 is used to bear the head and upper body of the patient, and the second portion 213 of the main plate 21 is used to bear the hips and lower limbs of the patient. When the patient is on the conduit bed 1, the patient generally sits on the second portion 213 of the main plate 21 through the hips first, so the transition portion 22 can be arranged on the edge of the peripheral side of the second portion 213 according to the actual situation, so that the transition portion 22 does not need to be arranged on the entire peripheral side of the main plate 21, and the edge of the bed plate 20 can also reduce the impact on the patient, thereby reducing the production cost of the bed plate 20

[0045] In some embodiments of the present application, the support rail 30 and the bed plate 20 have an adhesive layer (not shown in the figure), and the upper side of the support rail 30 is fixedly connected to the main plate surface 211 and the arc-shaped transition surface 221 through the adhesive layer, so that the support rail 30 and the bed plate 20 are integrally connected, thereby enhancing the stability of the overall structure.

[0046] It should be noted that the adhesive layer is made of high-strength adhesive to ensure firm connection, and has a certain elasticity to buffer the vibration during movement. The elastic properties of the adhesive layer can effectively absorb the slight impact during movement, further reduce noise, and further improve the stability of the bed plate 20 and the comfort of the patient. The high-strength adhesive of the adhesive layer can be made of environmentally friendly materials, which meets the safety standards of medical equipment, ensures the health of the patient, and improves the environmental performance of the equipment.

[0047] Further, the thickness of the adhesive layer is L1, and L1 satisfies 0.6mm≤L1≤1.2mm. Specifically, by controlling the thickness of the adhesive layer, the adhesive layer can provide sufficient adhesive strength for the support rail 30 and the bed plate 20, and also maintain a certain elasticity, so that the bed plate 20 is stable and quiet during movement, and further improves the overall performance of the equipment.

[0048] Please refer to Figures 4-5 In some embodiments of the present application, the conduit bed 1 further includes a reinforcing portion 40, the reinforcing portion 40 is arranged below the main plate surface 211 and is located on the inner side of the support rail 30, and the reinforcing portion 40 is connected with the main plate surface 211 and the support rail 30.

[0049] Specifically, in order to further improve the stability of the bed plate 20, the conduit bed 1 of the present application is provided with a reinforcing part 40 between the support rail 30 and the bed plate 20, so that the reinforcing part 40 can disperse the pressure borne by the bed plate 20 and prevent the bed plate 20 from deforming due to long-term use or overloading. At the same time, the reinforcing part 40 is arranged at the bottom of the bed plate 20, which ensures that it enhances the stability without affecting the flexibility of the bed plate 20 and the overall appearance of the conduit bed 1.

[0050] The reinforcing part 40 and the bed plate 20 can be manufactured by one-piece molding, or they can be fixed by other connection methods such as bonding, screwing, etc. In addition, the reinforcing part 40 can be made of high-strength composite material, which effectively enhances the overall structural rigidity of the bed plate 20, prevents the bed plate 20 from deforming, and further improves the load-bearing capacity of the bed plate 20.

[0051] Further, please refer to Figures 4-5 In some embodiments of the present application, the upper side of the support rail 30 includes a first side 31, a second side 32 and a third side 33 connected in sequence, the first side 31 is closely fitted and fixed with the arc-shaped transition surface 221, the second side 32 is closely fitted and fixed with the main plate surface 211, and the third side 33 is closely fitted and fixed with the reinforcing part 40. That is, each part of the upper side of the support rail 30 is bonded with the bed plate 20 and the reinforcing part 40, which increases the contact area between the support rail 30 and the bed plate 20 and the reinforcing part 40, thereby dispersing the stress between the bed plate 20 and the support rail 30 and reducing the stress concentration point, which helps to reduce the possibility of local deformation, ensures more firm bonding, and effectively improves the connection strength between the bed plate 20 and the support rail 30.

[0052] The first side 31 and the third side 33 are both arranged as arc surfaces, which ensures that the connection between each part of the upper side of the support rail 30 and the bed plate 20 and the reinforcing part 40 is smooth and seamless, further improving the connection strength and stability between the bed plate 20 and the support rail 30.

[0053] It can be understood that, as Figure 5As shown, the reinforcing part 40 has a first end face 41 which is connected with the third side face 33. Since the third side face 33 is arc-shaped, the first end face 41 of the reinforcing part 40 is also arc-shaped, so as to ensure the close connection between the first end face 41 and the third side face 33. That is, the arc-shaped transition surface 221, the partial main plate surface 211 and the first end face 41 can jointly form a groove-like structure, and the upper side of the support rail 30 is located in the groove-like structure and is completely connected with the groove wall of the groove-like structure. In addition, the thickness of the reinforcing part 40 is not more than the thickness of the support rail 30, so as to prevent the reinforcing part 40 from interfering with the sliding process of the bed plate 20.

[0054] Further, referring to Figure 5 In some embodiments of the present application, the opposite two ends of the lower side of the bed plate 20 are provided with the support rails 30, and the reinforcing part 40 is located between the two support rails 30, and the two sides of the reinforcing part 40 are respectively connected with the third side face 33 of the two support rails 30.

[0055] It can be understood that the support rails 30 are symmetrically arranged on the lower side of the bed plate 20, so that the pressure of the bed plate 20 can be evenly distributed when the bed plate 20 is subjected to external force, thereby avoiding local stress concentration and improving the stability of the bed plate 20. At the same time, the close combination of the support rail 30 and the reinforcing part 40 can ensure that the bed plate 20 always remains stable during the movement.

[0056] In some embodiments of the present application, the base 10 includes a seat body and a first track (not shown in the figure), and the first track is arranged on the upper side of the seat body. The support rail 30 is in sliding connection with the first track, and the first track can guide and limit the sliding of the support rail 30, so as to prevent the bed plate 20 from being dislocated during the sliding. At the same time, the first track provides a sliding basis for the support rail 30, so as to ensure that the bed plate 20 moves smoothly and stably. The seat body can be made of high-strength material, so as to provide stable support for various structures on the upper side of the seat body, and further improve the stability and durability of the overall structure.

[0057] For example, the support rail 30 is provided with a guide groove 34, and when the bed plate 20 is installed on the base 10, at least part of the first track on the base 10 is located in the guide groove 34. When the support rail 30 slides relative to the first track, the guide groove 34 can limit the support rail to slide in a predetermined direction.

[0058] In a second aspect, the embodiments of the present application also provide an angiography X-ray machine (not shown in the figure), which includes a scanning device, a display device and the catheter bed 1 as described in any of the above embodiments. The scanning device has a containing space, and the catheter bed 1 is located in the containing space. The display device is electrically connected with the scanning device, so as to receive the scanning result of the scanning device.

[0059] Specifically, the scanning device scans the human body through a high-precision instrument, and transmits the scanning data to the display device, and the display device displays the collected image data in real time, which facilitates the doctor to accurately diagnose and treat the patient, and the design of the catheter bed 1 ensures the stability and comfort of the patient during the scanning process.
