Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a mobile base catheter bed and medical equipment. Background Technology
[0002] Digital subtraction angiography (DSA) is a novel X-ray imaging system that combines conventional angiography with computer image processing technology. DSA aims to remove interfering images that overlap with blood vessels to obtain clear vascular images, which is beneficial for disease diagnosis and interventional procedures. The basic principle of subtraction angiography is to subtract two images of the same part of the body to obtain the difference. The image without contrast agent is called a mask image, and the image obtained after injecting contrast agent is called an angiographic image or filling image. In existing technologies, fixed-base catheter beds are used to suspend DSA equipment. However, with the need for larger-area irradiation, fixed-base catheter beds are increasingly unable to meet practical requirements. Utility Model Content

[0025] Please refer to the following: Figure 1 This embodiment provides a movable base catheterization bed 10 and a medical device using the movable base catheterization bed 10, the medical device being a DSA device. The movable base catheterization bed 10 and the medical device can improve the technical problem in the prior art where fixed base catheterization beds cannot meet the needs of large-area irradiation.
[0026] Please refer to the following: Figures 1 to 7The mobile base catheterization bed 10 includes a bed body 100, a lifting seat 200, a track assembly 300, a drag chain assembly 400, and a moving component 500. The bed body 100 is used to support the patient, facilitating the patient's placement within the device's working range. The lifting seat 200 is connected to the bottom of the bed body 100; the lifting seat 200 enables the bed body 100 to move up and down. The configuration of the lifting seat 200 is existing technology and will not be described further. The lifting seat 200 is slidably connected to the track assembly 300, and the lifting seat 200 can slide horizontally relative to the track assembly 300. Generally, the lifting seat 200 and the bed body 100 can slide relative to the track assembly 300 as a whole, the sliding trajectory is generally a straight line, and the lifting seat 200 and the bed body 100 can reciprocate along this trajectory under external force. The cable chain assembly 400 has a cable chain 410 and a movable pulley 420. One end of the cable chain 410 is fixedly connected to the lifting base 200, and the movable pulley 420 is movably connected to the lifting base 200. The movable member 500 is slidably connected to the track assembly 300, and the cable chain 410 passes around the movable pulley 420 and is connected to the movable member 500 at the other end.
[0027] It is worth noting that during the movement of the bed 100 and the lifting seat 200 relative to the track assembly 300, since one end of the drag chain 410 is fixed to the lifting seat 200, it can move with the lifting seat 200; while the other end is connected to the moving part 500, causing the drag chain 410 to move synchronously. This is manifested by the sliding of the movable pulley 420 up and down, and the drag chain 410 sliding around the movable pulley 420. Some cables or catheters of the medical equipment are located inside the drag chain 410, which can provide protection for them.
[0028] As described above, in this mobile base catheter bed 10, the bed body 100 and the lifting seat 200 can move horizontally relative to the track assembly 300 as a whole to increase the irradiation range of the DSA equipment using this mobile base catheter bed 10. Simultaneously, as the bed body 100 and the lifting seat 200 move, the drag chain 410 slides around the movable pulley 420. When the movable pulley 420 reaches its limit position, the movement distance of the drag chain 410 can be further extended by the movement of the moving component 500 relative to the track assembly 300, thereby further increasing the movement distance of the bed body 100 and the lifting seat 200. This achieves the purpose of further increasing the travel distance of the bed body 100 and the lifting seat 200, thus increasing the irradiation range of the DSA equipment using the mobile base catheter bed 10. Therefore, this mobile base catheter bed 10 can effectively improve the technical problem that fixed base catheter beds in the prior art cannot meet the needs of large-area irradiation.
[0029] It should be noted that when the drag chain 410 is installed, and the movable pulley 420 moves from one extreme position to another during its travel, the travel distance of the bed 100 and the lifting seat 200 is twice the travel distance of the movable pulley 420. However, when the moving component 500 is installed, the travel distance of the bed 100 and the lifting seat 200 is further extended. The travel distance of the bed 100 and the lifting seat 200 relative to the track assembly 300 is calculated as twice the travel distance of the movable pulley 420 plus the travel distance of the moving component 500. Based on this, the travel distance of the bed 100 and the lifting seat 200 can be increased, thereby improving the technical problem that fixed-base type catheter beds in the prior art cannot meet the needs of large-area irradiation.
[0030] Furthermore, in this embodiment, the movable base guide bed 10 also includes a first elastic element 510; one end of the first elastic element 510 is fixed to the track assembly 300, and the other end is connected to the movable element 500. When the first elastic element 510 is provided, when the bed body 100 and the lifting seat 200 are moved, the drag chain 410 and the movable pulley 420 will move immediately. Due to the elastic effect of the first elastic element 510, when the force of the drag chain 410 and the movable pulley 420 does not overcome the elastic force of the first elastic element 510, the movable element 500 will remain stationary. When the movable pulley 420 moves to the limit position within its travel stroke, the force applied to the bed body 100 and the lifting seat 200 is transmitted to the movable element 500. When the force overcomes the elastic force of the first elastic element 510, the movable element 500 is moved, thereby realizing further movement of the bed body 100 and the lifting seat 200.
[0031] During the return process of the bed 100 and the lifting seat 200, the elastic force of the first elastic element 510 first drags the moving part 500 back to its original position, and then completes the return of the drag chain 410 and the movable pulley 420.
[0032] To facilitate the return of the movable pulley 420 and the cable chain 410, in this embodiment, the cable chain assembly 400 further includes a second elastic element 430; one end of the second elastic element 430 is fixedly connected to the lifting seat 200, and the other end is connected to the movable pulley 420. During the movement of the bed 100 and the lifting seat 200, the movable pulley 420 causes the second elastic element 430 to undergo elastic deformation; when the bed 100 and the lifting seat 200 return to their original positions, the elastic force of the second elastic element 430 drives the movable pulley 420 to return to its original position, simultaneously realizing the return of the cable chain 410.
[0033] It is worth noting that in this embodiment, the elastic coefficient of the second elastic element 430 is less than that of the first elastic element 510. Therefore, during the movement of the bed 100 and the lifting seat 200 from their initial positions, the drag chain 410 and the movable pulley 420 move first. When the movable pulley 420 reaches its limit position within its travel stroke, the movement of the moving element 500 is achieved by external force overcoming the elasticity of the first elastic element 510.
[0034] Of course, in other embodiments, if the elastic coefficient of the first elastic element 510 is less than that of the second elastic element 430, during the movement of the bed 100 and the lifting seat 200 from their initial positions, the moving element 500 will move first. When the moving element 500 reaches its limit position within its travel stroke, the moving pulley 420 and the cable chain 410 will move based on external force overcoming the elasticity of the second elastic element 430. Alternatively, when the elastic coefficients of the first elastic element 510 and the second elastic element 430 are the same, various situations may occur; for example, the moving element 500 moves first, followed by the moving pulley 420 and the cable chain 410; for another example, the moving pulley 420 and the cable chain 410 move first, followed by the moving element 500; and for yet another example, the moving pulley 420 and the cable chain 410 move synchronously with the moving element 500.
[0035] In this embodiment, both the first elastic element 510 and the second elastic element 430 are torsion springs. It should be understood that in other embodiments, at least one of the first elastic element 510 and the second elastic element 430 may also be configured as other types of elastic elements, such as helical springs or pneumatic elastic devices.
[0036] In this embodiment, the cable chain assembly 400 further includes a pull rod 440 and an isolation sleeve 450; two second elastic members 430 are provided, with the ends of the two second elastic members 430 away from the lifting seat 200 respectively connected to the two ends of the pull rod 440; the isolation sleeve 450 is fitted onto the pull rod 440; and a movable pulley 420 is connected to the isolation sleeve 450. The isolation sleeve 450 facilitates the rotation of the movable pulley 420 relative to the pull rod 440, thereby facilitating the movement of the cable chain 410 relative to the movable pulley 420. By providing two second elastic members 430, the position of the cable chain 410 on the pull rod 440 can be adjusted according to actual conditions, so that the cable chain 410 can meet the positioning requirements of cables or conduits. At the same time, by providing two second elastic members 430 at both ends of the pull rod 440, the stability of the pull rod 440 when pulled by the passive pulley 420 can be ensured.
[0037] Of course, the number of second elastic elements 430 and the arrangement of pull rods 440 and isolation sleeves 450 can be adjusted based on actual conditions. For example, in some cases, the pull rods 440 and isolation sleeves 450 can be omitted, so that the end of the second elastic element 430 is directly connected to the movable pulley 420.
[0038] In this embodiment, the track assembly 300 is provided with a first limiting member 520, and the movable member 500 is provided with a sliding groove 501; the first limiting member 520 is disposed in the sliding groove 501. When the movable member 500 moves relative to the track assembly 300, the first limiting member 520 slides in the sliding groove 501, and the movement stroke of the movable member 500 is determined based on the length of the sliding groove 501. That is, when the first limiting member 520 abuts against the two ends of the sliding groove 501, the movement of the movable member 500 is restricted.
[0039] The movable component 500 has sliding grooves 501 on both opposite sides. Correspondingly, the track assembly 300 has first limiting members 520 corresponding to the two sliding grooves 501, with the two first limiting members 520 extending into the two sliding grooves 501 respectively. On the one hand, the cooperation between the two first limiting members 520 and the two sliding grooves 501 can provide stable stroke limitation; on the other hand, the cooperation between the two first limiting members 520 and the two sliding grooves 501 can also guide the movement of the movable component 500, ensuring that the movable component 500 moves along a specified trajectory.
[0040] It should be understood that in other embodiments, the travel limit of the moving member 500 may also be implemented in other ways. For example, a groove for the moving member 500 to slide is provided on the track assembly 300, and the length of the groove determines the travel of the moving member 500. That is, when the moving member 500 abuts against the two ends of the groove, the travel of the moving member 500 is limited, thus determining the travel of the moving member 500.
[0041] In addition, in this embodiment, the cable chain assembly 400 further includes a second limiting member 460, which is fixed to the track assembly 300 and disposed on at least one side of the cable chain 410 to limit the swing of the cable chain 410. In some cases, the second limiting member 460 may have a hole through which the cable chain 410 passes, which can provide a guiding function for the cable chain 410 and limit the swing of the cable chain 410. In other cases, the second limiting member 460 may only be disposed on both sides of the cable chain 410, thereby limiting the swing of the cable chain 410 by blocking it.
[0042] In this embodiment, the cable chain assembly 400 also includes a guide wheel 470, which is fixedly connected to the lifting seat 200. The cable chain 410 passes around the guide wheel 470 and is connected to the moving part 500. During the movement of the bed 100 and the lifting seat 200, as the movable pulley 420 moves, the cable chain 410 changes from a vertical state to a horizontal state. At the bending position of the cable chain 410, the cable chain 410 is prone to large swing amplitude. Based on this, the guide wheel 470 not only facilitates the switching of the cable chain 410 between the vertical and horizontal states, but also achieves the purpose of tightening the cable chain 410, preventing excessive swing amplitude of the cable chain 410 from damaging the cables or conduits.
[0043] In addition, in this embodiment, the movable base guide bed 10 also includes a protective cover 530, which is fixedly connected to the track assembly 300 and covers the movable member 500. It is worth noting that the protective cover 530 also covers the first elastic member 510, thereby providing protection for both the movable member 500 and the first elastic member 510 through the protective cover 530.
[0044] In summary, in the mobile base catheterization bed 10 and medical device provided in this embodiment, the bed body 100 and the lifting seat 200 can move horizontally relative to the track assembly 300 as a whole, thereby increasing the irradiation range of the DSA device using the mobile base catheterization bed 10. Simultaneously, as the bed body 100 and the lifting seat 200 move, the drag chain 410 slides around the movable pulley 420. When the movable pulley 420 reaches its limit position, the movement distance of the drag chain 410 can be further extended by the movement of the moving component 500 relative to the track assembly 300, thereby further increasing the movement distance of the bed body 100 and the lifting seat 200. This achieves the goal of further increasing the movement stroke of the bed body 100 and the lifting seat 200, thus increasing the irradiation range of the DSA device using the mobile base catheterization bed 10. Therefore, the mobile base catheterization bed 10 can effectively improve the technical problem that fixed base catheterization beds in the prior art cannot meet the needs of large-area irradiation. Furthermore, based on the configuration of the first elastic element 510 and the second elastic element 430, it is easier for the movable pulley 420, the cable chain 410 and the movable pulley 420 to return to their original positions, thereby ensuring a smoother overall movement process and preventing the cable chain 410 or cables from overlapping.
[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
