Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a universal testing scanning bed. Background Technology

[0002] Image quality from CT systems is crucial for medical diagnosis, thus requiring regular image testing and calibration. Traditional testing processes typically require actual medical scanning beds, which are not only time-consuming and labor-intensive but may also interfere with the proper functioning of the medical equipment. The primary function of the scanning bed during image testing is to mount different scanning dies and adjust their positions according to system commands. Traditional medical scanning beds have the following drawbacks in this process:

[0003] 1. Poor flexibility: Different models and configurations of CT systems use different scanning beds, involving dozens of types of scanning beds;

[0004] 2. High cost: Medical scanning beds are designed based on real medical scenarios, and their functions and performance indicators far exceed the requirements of the image scanning process, resulting in a waste of testing costs;

[0005] 3. Inconvenient to operate: Medical scanning beds are very large and heavy, making them difficult to operate and maintain in testing scenarios that require frequent movement, and they are also very prone to being bumped and damaged.

[0006] In summary, existing traditional medical scanning beds suffer from drawbacks such as poor flexibility, high cost, and inconvenient operation. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Reference Figures 1 to 3 This utility model provides a universal testing scanning bed that can solve the shortcomings of traditional medical scanning beds in the prior art, such as poor flexibility, high cost and inconvenient operation.

[0029] The present invention provides a general-purpose test scanning bed 100, comprising: a base 10, a vertical lifting mechanism 20, a bed board base 30, a first horizontal moving guide rail 40, a second horizontal moving guide rail 50, and a control system 60.

[0030] A vertical lifting mechanism 20 is disposed on the upper surface of the base 10; the bed base 30 is disposed parallel to the base 10, and the bed base 30 is disposed at the lifting end of the vertical lifting mechanism 20, so that the vertical lifting mechanism 20 drives the bed base 30 to rise or fall; a first horizontal moving guide rail 40 is disposed parallel to the upper surface of the bed base 30, and the moving end of the first horizontal moving guide rail 40 moves along the length direction of the bed base 30 and extends to the outside of the bed base 30; a second horizontal moving guide rail 50 is disposed horizontally at the moving end of the first horizontal moving guide rail 40, and the moving end of the second horizontal moving guide rail 50 moves along the length direction of the first horizontal moving guide rail 40 and extends to the outside of the first horizontal moving guide rail 40, and the moving end of the second horizontal moving guide rail 50 is provided with a scanning mold; a control system 60 is disposed on the base 10, and the vertical lifting mechanism 20, the first horizontal moving guide rail 40 and the second horizontal moving guide rail 50 are all connected to the control system 60.

[0031] In this application, the universal test scanning bed uses an electric adjustment mechanism to realize the movement of the scanning platform. In addition, this application is equipped with sensors and a feedback system to realize real-time monitoring and control of the scanning process. At the same time, it is connected to the CT system 200 through a dataset interface to realize signal transmission.

[0032] In addition, compared with traditional medical scanning beds, this application eliminates the original bed panel and redesigns a simplified motion system (vertical lifting mechanism 20, first horizontal moving guide rail 40 and second horizontal moving guide rail 50) and control system, and adds ergonomic mechanical components. Since the test scanning bed will not be used to carry real patients, but only to carry scanning molds, the components in this application can be made of suitable lightweight materials (such as plastics) without having to consider structural requirements such as human comfort. The size and shape of the scanning platform (mechanical structure) can be adapted to different types of test models. In addition, this application can also be configured with various accessories as needed, such as multi-functional mold frames, image calibration modules, etc., to meet diverse testing scenarios.

[0033] The first horizontal moving guide rail 40 and the second horizontal moving guide rail 50 in this application are existing products. The moving end of the first horizontal moving guide rail 40 and the second horizontal moving guide rail 50 is a lead screw and slide rail. Its transmission end consists of a lead screw motor and a lead screw. The lead screw nut is fixed at the moving end. The movement of the lead screw motor drives the lead screw to rotate, thereby driving the lead screw nut to move, and then driving the moving end fixed on the lead screw nut to move. When the first horizontal moving guide rail 40 extends to its maximum length position, the second horizontal moving guide rail 50 continues to extend to the maximum length position of the entire scanning platform. At this time, the scanning mold is mounted on the surface of the moving end of the second horizontal moving guide rail 50 to complete the system-level test. When the first horizontal moving guide rail 40 and the second horizontal moving guide rail 50 both extend to their maximum length positions, the bed plate base 30, the first horizontal moving guide rail 40 and the second horizontal moving guide rail 50 are in a stepped shape.

[0034] The vertical lifting mechanism 20 is also an existing product. The vertical lifting mechanism 20 and the bed base 30 are connected by bearings. The vertical lifting mechanism 30 is fixedly connected to the hydraulic rod inside. The hydraulic pump controls the up and down movement of the hydraulic rod, thereby controlling the lifting of the bed base 30.

[0035] The control system 60 is also an existing product. The core control board in the control system 60 is equipped with custom firmware. This firmware can shield some signals and characteristic settings that are not needed for test scans, simplifying the control logic, while retaining precise parameter and position control.

[0036] Furthermore, the newly designed and simplified motion system of this application (vertical lifting mechanism 20, first horizontal moving guide rail 40 and second horizontal moving guide rail 50), in conjunction with the control system 60, can simulate the motion of a real scanning bed while retaining precise control feedback of motion parameters and position. It retains the original medical scanning bed's core control board and signal connection board. On this basis, according to the new scanning platform, the corresponding size and specifications of the horizontal transmission mechanical components (first horizontal moving guide rail 40 and second horizontal moving guide rail 50) are configured, reducing the overall design specifications of the vertical lifting mechanism 20 (the load-bearing capacity is reduced from about 300kg to 20kg).

[0037] This utility model provides a universal test scanning bed 100, which is mounted on the upper surface of a base 10 via a vertical lifting mechanism 20. A bed base 30 is parallel to the base 10 and is positioned at the lifting end of the vertical lifting mechanism 20, allowing the mechanism to raise or lower the bed base 30. A first horizontal moving guide rail 40 is parallel to the upper surface of the bed base 30, and its moving end extends along the length of the bed base 30 to the outside of the bed base 30. A second horizontal moving guide rail 50 is horizontally positioned at the moving end of the first horizontal moving guide rail 40, and its moving end extends along the length of the first horizontal moving guide rail 40. The moving end of the second horizontal moving guide rail 50 is equipped with a scanning mold, extending to the outside of the first horizontal moving guide rail 40. The control system 60 is mounted on the base 10, and the vertical lifting mechanism 20, the first horizontal moving guide rail 40, and the second horizontal moving guide rail 50 are all connected to the control system 60. Therefore, the universal test scanning bed of this application can simulate the role of a real scanning bed in CT system image testing, and has high substitutability and reliability. Through the control system and optional accessories, it can meet different testing needs and is suitable for image testing of various CT systems 200. In addition, compared with using a real medical scanning bed, the universal test scanning bed of this application has lower cost and is easier to operate, saving time and labor costs. Therefore, this utility model solves the defects of traditional medical scanning beds in the prior art, such as poor flexibility, high cost, and inconvenient operation.

[0038] Reference Figure 3 Optionally, the general-purpose test scanning bed is equipped with a data interface that is connected to the CT system 200.

[0039] The data interface is connected to the CT system 200, which can receive and process control commands and real-time signals from the CT system 200. The data interface of this universal test bed is completely consistent with that of traditional medical scanning beds, ensuring seamless switching and replacement.

[0040] Reference Figure 1 Optionally, the general-purpose test scanning bed also includes a movable base 70, on which the base 10, vertical lifting mechanism 20, bed board base 30, first horizontal moving guide rail 40, second horizontal moving guide rail 50 and control system 60 are all mounted.

[0041] The movable base 70 is equipped with casters at the bottom. The base 10, vertical lifting mechanism 20, bed base 30, first horizontal moving guide rail 40, and second horizontal moving guide rail 50 of this application are made of lightweight materials, and their external dimensions, volume, and weight have been significantly changed. Therefore, the base 10, vertical lifting mechanism 20, bed base 30, first horizontal moving guide rail 40, and second horizontal moving guide rail 50 can be fixed on the movable base 70, which improves the ease of operation.

[0042] Optionally, the universal test scanning bed also includes a handle, which is provided on the movable base 70.

[0043] The above settings allow testers to easily control the direction and stop direction during movement.

[0044] Optionally, the universal test scanning bed also includes an operating lever, which is mounted on a movable base 70.

[0045] The above settings allow testers to easily control the direction and stop direction during movement.
