Description

Technical Field

[0001] The present invention relates to the technical field of imaging detection lying flat equipment, in particular to a lying flat equipment for imaging equipment detection. Background Art

[0002] Imaging equipment testing is the process of evaluating the performance, verifying functionality, and conducting safety tests on devices that generate images or visualize information, such as medical imaging equipment and industrial testing equipment. Its core purpose is to ensure that the equipment meets relevant standards and requirements in terms of imaging quality, accuracy, stability, and operational safety.

[0003] Traditional examination beds are usually fixed structures. Patients with limited mobility or critical conditions need to be manually transported to the examination bed multiple times. During this process, patients may suffer secondary injuries due to bumps, improper posture, or operational errors. The risk is particularly increased for patients with trauma such as fractures. When the examination equipment is equipped with its own bed, the patient needs to be transferred from a stretcher or walking to the examination bed. The operation process is cumbersome and time-consuming, which not only reduces medical efficiency but also increases the risk of cross-infection due to multiple contacts with different beds. The bed board of the examination bed is mostly a rigid fixed structure that cannot provide dynamic support according to the patient's body shape and body contours. When patients are examined for a long time, the body pressure is concentrated in a local area, which can easily cause discomfort. For special patients such as fractures, the fixed bed board cannot disperse the pressure, and the vibration during transportation may also aggravate the injury. Summary of the Invention

[0004] The purpose of the present invention is to provide a lying device for imaging equipment detection, which solves the problems in the existing technology that the detection bed does not have transportation safety, equipment adaptability, support comfort and operation convenience.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A lying device for imaging equipment inspection comprises a base frame, the top of which is connected to a bracket; a lifting mechanism connected between the base frame and the bracket, for driving the bracket to adjust its height in the vertical direction; a moving assembly is arranged on the top of the bracket, and a stretcher assembly is detachably mounted on the top surface of the bracket; The stretcher assembly includes three bed boards arranged in sequence along the length direction. The adjacent bed boards are hinged at the end through a rotating connecting piece to form a foldable three-section structure; the surface of the bed board is evenly provided with airbag units for supporting the patient's body, and the inside of the bed board is provided with an inflation assembly for supplying air to the airbag unit.

[0006] Preferably, two groups of adjustment components are symmetrically arranged on the surface of the bracket, and each group of adjustment components is respectively connected to the bed board at the corresponding end for driving the bed boards at both ends to rotate relative to the middle bed board, thereby adjusting the inclination angle between the bed boards.

[0007] Preferably, the bed board includes a breathable plate, a connecting frame and a rubber pad, the breathable plate is fixedly mounted on the bottom end of the connecting frame, and the rubber pad is fixedly mounted on the top of the connecting frame and protrudes from the connecting frame.

[0008] Preferably, the airbag units are evenly distributed on the surface of the rubber pad, and both the top and the bottom pass through the rubber pad, and a pressure sensor is provided on the top of the airbag unit.

[0009] Preferably, the inflation assembly includes an air pump and a pipeline, the pipeline includes a main pipeline and a branch pipeline with a solenoid valve, the branch pipelines are evenly connected to the surface of the main pipeline, and each branch pipeline is connected to a different airbag unit respectively, the air outlet end of the air pump is connected to the main pipeline, and the air pump and the pipeline are fixedly installed on the surface of the breathable plate.

[0010] Preferably, the stretcher assembly further comprises an H-shaped connecting frame, a middle bed board among the three bed boards is fixedly connected to the H-shaped connecting frame, and handles are provided at both ends of the H-shaped connecting frame.

[0011] Preferably, the lifting mechanism includes a bidirectional hydraulic cylinder and two rotating frames. The bidirectional hydraulic cylinder is fixedly mounted on the surface of the base frame. Sliders are fixedly mounted on both output ends of the bidirectional hydraulic cylinder. The slides are slidably connected to the base frame. The two rotating frames are respectively rotatably connected to the two sliders. The top ends of the two rotating frames are rotatably connected to the bracket.

[0012] Preferably, the surface of the bracket is provided with two sliding grooves adapted to the moving component and two through holes adapted to the adjusting component.

[0013] Preferably, the adjustment component includes a fixed plate, which is fixedly mounted on the surface of the bracket, and two telescopic sleeves are fixedly mounted on the surface of the fixed plate, and the telescopic ends of the two telescopic sleeves are fixedly mounted with the same cross bar, and the surface of the cross bar is rotatably connected to two rollers, and a hydraulic rod is fixedly mounted on the surface of the fixed plate, and the output port of the hydraulic rod is fixedly connected to the cross bar, and the bottom of the three bed boards near the two ends are welded with tracks corresponding to the rollers.

They can provide adaptive support according to the patient's body contour, evenly disperse body pressure, and effectively support the patient's body, especially for accidental fractures. Since different parts of the body are supported, secondary injuries caused during the transfer process can be effectively reduced. In addition, the flexible cushioning characteristics of the airbag can absorb vibrations and reduce the impact of external impact on the patient's body.

[0016] The detachable stretcher design allows patients to lie directly on the stretcher assembly in an emergency. The precise sliding of the moving assembly allows for seamless docking between the stretcher and the examination equipment bed. This is particularly useful for patients with limited mobility, as the stretcher and patient can be transferred to the examination equipment without a secondary transfer. This avoids the risk of patients needing to move or being repeatedly moved during traditional transport, minimizing any secondary injuries to the patient caused by bumps or improper handling during transport.

[0017] The detachable connection between the mobile assembly and the stretcher assembly not only allows for the flexibility of independent stretcher use, but also, through sliding cooperation with the bracket, enables efficient transfer of patients between examination devices. For examination facilities equipped with their own beds, the stretcher assembly and patient can be directly moved horizontally to the target bed, eliminating the cumbersome process of patient transfer, significantly improving medical operation efficiency, and reducing the risk of cross-infection caused by multiple transfers. It is particularly suitable for critically ill or immobile patients. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In summary, the matrix airbag unit 412 on the surface of the bed board 41 dynamically supplies air through the inflation component, combined with real-time monitoring and adjustment by the pressure sensor 7, to evenly disperse the patient's body pressure, thereby reducing secondary damage to the patient during the patient's transfer. The independent control of the airbag can fit patients of different body shapes and provide personalized support.

[0039] The entire lying-down device can be separated into a stretcher component 4, so that the patient can lie on the stretcher component 4 and be carried by medical staff. Patients with limited mobility can be easily transferred without having to move themselves, or the patient can be directly helped to lie on the bed for examination.

[0040] The entire stretcher assembly 4 is arranged on the mobile assembly 6. When a patient needs to be examined, if the examination equipment itself has an examination bed, but it is inconvenient for the patient to be transferred, the entire bracket 3 can be raised and lowered, and then the H-shaped connecting frame 43 in the mobile assembly 6 drives the entire stretcher assembly 4 to be moved directly to the examination bed, so that the patient can be examined without being transferred.
