Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a radiation protection screen. Background Art

[0002] Malignant tumors have become the main killers endangering people's health. PET / CT is mainly used for the early detection and diagnosis of malignant tumors and can provide detailed molecular information such as the function and metabolism of lesions. However, PET / CT itself has radioactive metabolites. Although most of the radioactive substances have decayed during the examination, when the patient returns to the ward, the radioactive dose still exists, and the personnel within several meters around the patient will be exposed to a certain amount of radiation. Many patients undergo this examination during hospitalization, but the ward lacks effective equipment to protect the safety of the people around the examined patients.

[0003] Currently, the main method adopted is to let the examined patients drink more water after the examination, try to avoid moving around casually, and not go to crowded places. However, due to the reasons of the patients themselves or cognitive problems, many patients cannot drink water or stay outdoors for a long time. Summary of the Utility Model

[0041] A number of connected lead fan blades 2 provided within the bracket 1;

[0042] A rotating assembly for opening or closing the fan blades 2. The rotating assembly includes a rotating shaft 5 provided on the fan blades 2, and a first connecting rod 6 that rotatably connects one end of all the rotating shafts 5 within each bracket 1 and can move up and down. A cavity 7 is further provided within the first connecting rod 6, and the other end of the rotating shaft 5 is rotatably connected to the bracket 1;

[0043] A knob assembly provided on the bracket 1 and used to control the rotating assembly. The knob assembly includes a second connecting rod 8 inserted into the cavity 7, a knob 9 provided at one end of the second connecting rod 8 and located on the bracket 1, and a stopper 10 provided at the other end of the second connecting rod 8 and placed within the cavity 7. The stopper 10 is elliptical in shape. When the knob 9 is rotated, the stopper 10 rotates within the cavity 7, causing the first connecting rod 6 to rise or fall. When the long diameter of the cross-section of the stopper 10 is vertical, since the long diameter of the cross-section of the stopper 10 is equal to the height of the cavity 7, the stopper 10 can be supported and fixed within the cavity 7. The first connecting rod 6 rises until the fan blades 2 are in an open state and can be fixed; when the stopper 10 continues to rotate, the first connecting rod 6 descends and the fan blades 2 are in a closed state.

[0044] Rollers 3 provided at the bottom of the bracket 1 and used for sliding. A connecting member 11 for connecting the rollers 3 is provided at the bottom of the bracket 1. The connecting member 11 is in an inverted T shape, including a longitudinal portion connected to the bottom of the bracket 1 and a transverse portion integrated with the longitudinal portion. Rollers 3 are provided at both ends of the transverse portion. Brake pads are provided on the rollers 3. When the radiation protection screen is moved to a specified position, the brake pads can be stepped on to fix the rollers 3, thereby fixing the radiation protection screen.

[0045] In order to prevent the rollers 3 at the bottom of each bracket 1 from colliding with each other when the radiation protection screen is folded, the inverted T-shaped connecting member 11 is provided at different positions at the bottom of each bracket 1 within the radiation protection screen. When the radiation protection screen is composed of 5 groups of brackets, the inverted T-shaped connecting members are respectively provided at the 1 / 5, 2 / 5, 3 / 5, 4 / 5, 5 / 5 positions or 1 / 5, 2 / 5, 4 / 5, 3 / 5, 5 / 5 positions or 1 / 5, 3 / 5, 2 / 5, 4 / 5, 5 / 5 positions or 1 / 5, 3 / 5, 4 / 5, 2 / 5, 5 / 5 positions or 1 / 5, 4 / 5, 2 / 5, 3 / 5, 5 / 5 positions or 1 / 5, 4 / 5, 3 / 5, 2 / 5, 5 / 5 positions of the brackets. Exemplarily, as Figure 3 shown, when the radiation protection screen is composed of 5 groups of brackets 1, the inverted T-shaped connecting members 1 are respectively provided at the 1 / 5, 4 / 5, 2 / 5, 3 / 5, 5 / 5 positions of the brackets 1.

[0046] The above description of the embodiments is provided to enable those of ordinary skill in the art to understand and use the utility model. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative efforts. Therefore, the utility model is not limited to the above embodiments, and the improvements and modifications made by those skilled in the art without departing from the scope of the utility model according to the disclosure of the utility model should be within the protection scope of the utility model.
