Abstract
Description
[Technical Field]
[0001] The present invention relates to the technical field of medical auxiliary devices, and in particular to a multi-function adjustable examination chair for chest DR imaging in radiology. [Background technology]
[0002] When performing chest DR examinations in radiology departments, patients must accurately adjust their body posture according to the instructions of medical staff to ensure high-quality imaging. However, many patients are unable to adjust their position quickly and accurately due to factors such as advanced age, difficulty walking, and lack of understanding, which reduces imaging efficiency and results in unstable image quality. Currently, there is a lack of dedicated equipment to actively assist patients in positioning themselves and guide them to the appropriate imaging position. Therefore, there is a strong demand for an adjustable chair that can quickly guide patients into a standard imaging position. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-functional adjustable chair with a reasonable structure, high degree of adjustment freedom, and easy operation, which can effectively assist the patient in adjusting their imaging posture and improve the efficiency and image quality of DR examinations.
[0004] Technical Means: The multi-function adjustable examination chair for radiology chest DR mainly includes a bottom support mechanism, a lifting and rotating assembly, a seat and an armrest mechanism. The lifting and rotating assembly includes an electric telescopic rod, a guide mechanism, a support plate, an electric motor, and a mounting plate. The electric telescopic rod is vertically disposed on a bottom support mechanism, and its upper end is fixedly connected to the support plate. A guide mechanism is provided between the support plate and the bottom support mechanism to ensure stability during lifting and lowering. The electric motor is mounted on the support plate, and its output shaft faces upward and is fixedly connected to the mounting plate to drive the mounting plate to rotate horizontally. The seat portion is joined to a mounting seat on a mounting plate via a mounting support at its bottom, and is fixed with bolts to form a detachable structure. The armrest mechanism includes armrest support rods symmetrically arranged on both sides of the mounting plate, with sleeves fixed to the outer ends of the armrest support rods. An armrest adjustment rod is fixedly connected to the bottom of the armrest and inserted into the sleeve. The adjustment rod has multiple positioning holes, which cooperate with the positioning pins and sleeves to allow for multi-stage adjustment of the armrest height. The bottom support mechanism includes a bottom plate, a front horizontal frame, and a rear horizontal frame connected to the front and rear of the bottom plate. Fixed legs are provided at the bottom of both ends of the front horizontal frame, and casters are provided at both ends of the rear horizontal frame. By pushing down on the rear side and lifting the front side off the ground, a structure is formed that can be easily moved by the casters. The controller is installed at the bottom of the mounting plate and is electrically connected to the electric telescopic rod and the electric motor. The chair comes with a wireless remote control, allowing doctors to remotely control the chair's lifting and rotation.
[0005] The advantages of this invention are as follows: 1. Remote electric adjustment: The chair height and horizontal rotation can be controlled by a wireless remote control, helping doctors precisely position the patient without entering the examination room, thereby improving efficiency and reducing medical radiation exposure. 2. Achieving both stability and flexibility: The guide mechanism ensures stability when lifting and lowering, and the base equipped with casters and fixed legs makes it easy to move and highly stable when installed. 3. Designed with usability in mind: The seat is removable for easy disinfection and replacement, and the armrest height is adjustable to accommodate differences in patient physiques. [Brief explanation of the drawings]
[0006] [Figure 1] Figure 1 is a three-dimensional view (1) of the present invention. [Figure 2] Figure 2 is a three-dimensional view (2) of the present invention. [Figure 3] Figure 3 is a three-dimensional view of the present invention (part 3). DETAILED DESCRIPTION OF THE INVENTION
[0007] As shown in Figures 1 to 3, the multifunctional adjustable chair of the present invention is centered around a lifting and rotating assembly. The electric telescopic rod 2 is the main lifting member, with its lower end fixed to the base support mechanism 1 and its upper end fixedly connected to the receiving plate 4. To prevent rocking during lifting and lowering, a guide mechanism 3 is symmetrically arranged between the receiving plate 4 and the base support mechanism 1. The guide mechanism 3 is composed of a fixed outer tube 301 and an inner rod 302 that slides up and down within it, and the upper end of the inner rod 302 is fixedly connected to the receiving plate 4. This ensures that the trajectory of the lifting and lowering movement is kept straight and stable. The rotation function is realized by an electric motor 5. The electric motor 5 is mounted on the receiving plate 4, and its output shaft is fixedly connected upward to the mounting plate 6. When the electric motor 5 is operated, the mounting plate 6 and the components mounted thereon rotate circumferentially in the horizontal direction. The seat 8 is joined to the mounting seat on the mounting plate 6 via the mounting support 7 at its bottom, and is fixed with bolts 15. This detachable structure makes it easy to clean and replace the seat 8. The armrest section 14 employs a mechanical positioning structure. Armrest support rods 9 are fixedly connected to both sides of the mounting plate 6, and sleeves 10 are fixed to the outer ends of the armrest support rods 9. An armrest adjustment rod 12 is fixedly connected to the bottom of the armrest section 14, and is inserted into the sleeve 10. By inserting a positioning pin 11 into one of a number of positioning holes 13 formed in the armrest adjustment rod 12, the height of the armrest section can be fixed at a desired height, and can be adjusted according to the patient's physique. A front horizontal frame 102 and a rear horizontal frame 103 are connected to the bottom plate 101 of the bottom support mechanism 1. Fixed legs 105 are provided at the bottom of both ends of the front horizontal frame 102 to support the main load. Casters 104 are provided at both ends of the rear horizontal frame 103, and when moving the chair, the rear side is pushed down to lift the front fixed legs 105, allowing the chair to be easily moved by the casters 104. When in use, the fixed legs 105 come into contact with the ground, ensuring stability. A controller 16 is installed at the bottom of the mounting plate 6 and is electrically connected to the electric telescopic rod 2 and the electric motor 5. The doctor sends commands using a wireless remote control, and the controller 16 receives the commands and controls the lifting and lowering operation of the electric telescopic rod 2 and the activation, stopping, and rotation direction of the electric motor 5, thereby enabling the chair posture to be adjusted remotely and continuously.
[0008] Operating principle: With the patient seated on the seat 8, the doctor uses a remote control from the control room to control the chair's elevation or horizontal rotation, guiding the patient to a predetermined standard projection position. The guide mechanism 3 ensures stable elevation and the armrests can be adjusted to a comfortable height as needed. To move the device, simply push down on the rear to release the front, then push it forward on the casters for easy movement. [Explanation of symbols]
