Description

Technical Field

[0001] This utility model relates to the field of protective screen technology, specifically a foldable protective screen for a CT examination room. Background Technology

[0002] In the field of medical imaging examinations, especially during CT scans, high-energy X-ray radiation is generated, posing a potential hazard to medical staff and the surrounding environment. To reduce radiation exposure, protective barriers are usually required in examination rooms. Traditional protective screens mostly use fixed lead plate structures. Although the protective effect is reliable, fixed screens occupy the floor space of the examination room permanently and cannot be moved or stored during non-examination periods, which further reduces the utilization rate of the already limited medical space and affects equipment layout and personnel movement.

[0003] To address the aforementioned issues, existing technologies have proposed screens with folding effects. However, gaps exist at the hinge points of the panels, posing a risk of radiation leakage. Furthermore, there is often a gap between the bottom of the screen and the ground, allowing scattered radiation to escape from this area. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a protective screen that achieves efficient space utilization and provides comprehensive protection.

[0005] The technical solution adopted by this utility model to achieve the above objectives is: a foldable protective screen for a CT examination room, including a counterweight frame, a shielding plate and a hinge, wherein the shielding plate is provided in multiple sets, and each set of the shielding plate has a fitting part on both ends, and the front part of the fitting part is a fitting opening;

[0006] Multiple sets of shielding plates are connected sequentially by the hinge. When the multiple sets of shielding plates are unfolded, the fitting part at one end of one set of shielding plates fits into the fitting opening at one end of the adjacent set of shielding plates.

[0007] The counterweight frame is provided with a mounting part that matches the fitting opening. The mounting part is connected to the shielding plate at the head end through the hinge. When the shielding plate at the head end is unfolded, the mounting part fits into the fitting opening.

[0008] In the above technical solution, each set of shielding plates is fixedly connected to a caster wheel at the bottom, and a lead curtain is fixedly connected to the bottom of each set of shielding plates on one side of the caster wheel.

[0009] In the above technical solution, a limit assembly is fixedly connected to the shielding plate at the tail end;

[0010] The limiting component includes a mounting bracket, a screw, a friction disc, and a turntable. The mounting bracket is fixedly connected to the shielding plate near its bottom. The screw is threaded onto the mounting bracket. The friction disc is fixedly connected to the bottom end of the screw, and the turntable is fixedly connected to the top end of the screw.

[0011] In the above technical solution, a pusher is fixedly connected to the shielding plate at the tail end.

[0012] In the above technical solution, the shielding plate includes a stainless steel outer layer and a lead layer located inside the stainless steel outer layer.

[0013] In the above technical solution, at least one set of shielding plates between the head end shielding plate and the tail end shielding plate is provided with an observation port, and lead glass is fixedly connected inside the observation port.

[0014] In the above technical solution, the counterweight frame includes a counterweight base and a connecting frame fixedly connected to the counterweight base, and the connecting frame is provided with the mounting part.

[0015] In the above technical solution, the height of the shielding plate is not less than 2.5m.

[0016] The beneficial effects of this utility model are:

[0017] 1. Multiple shielding panels can be quickly unfolded and folded through hinges, forming a continuous protective barrier during examination and saving space when not in use, making it especially suitable for CT rooms with limited space;

[0018] 2. The tight fit between the fitting part and the fitting opening during unfolding ensures no gaps between the shielding plates, preventing radiation leakage and improving structural stability;

[0019] 3. The casters allow the screen to be moved easily, and the lead curtain at the bottom fills the gap between the casters and the ground, preventing scattered radiation from escaping from the bottom, thus balancing mobility and protective integrity.

[0020] 4. The turntable drives the screw to rotate, and the screw drives the friction plate to descend and come into contact with the ground. This utilizes the friction between the friction plate and the ground to ensure that the screen is firmly in place after it is unfolded, preventing accidental displacement during operation.

[0021] 5. The stainless steel outer layer is wrapped with a lead layer, which effectively absorbs X-rays, meets medical radiation protection standards, and is corrosion-resistant and easy to clean. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 A foldable protective screen for a CT examination room includes a counterweight frame, a shielding plate 100, and a hinge 200. The shielding plate 100 is provided in multiple sets, and the height of each set of shielding plates 100 is not less than 2.5m, so that it can completely cover the standing area of ​​the operator and reduce the radiation of scattered rays to medical staff. Each set of shielding plates 100 has a fitting part 101 on both ends, and the front of the fitting part 101 is a fitting opening 102.

[0031] The aforementioned multiple sets of shielding plates 100 are connected in sequence by hinges 200. When the multiple sets of shielding plates 100 are unfolded, the fitting part 101 at one end of one set of shielding plates 100 fits into the fitting opening 102 at one end of the adjacent set of shielding plates 100, so that there are no gaps at the hinge position, thereby preventing radiation leakage.

[0032] Furthermore, each of the aforementioned shielding plates 100 includes a stainless steel outer layer 103 and a lead layer 104 located inside the stainless steel outer layer 103. This structure can not only effectively absorb X-rays and meet medical radiation protection standards, but also has a more robust overall structure, is corrosion-resistant, and is easy to clean.

[0033] In addition, the counterweight frame is provided with a mounting part 301 for fitting the fitting port 102. The mounting part 301 is connected to the shielding plate 100 at the head end by a hinge 200. When the shielding plate 100 at the head end is unfolded, the mounting part 301 fits into the fitting port 102. This also avoids gaps between the counterweight frame and the shielding plate 100, which would cause radiation leakage.

[0034] Furthermore, the aforementioned counterweight frame includes a counterweight base 302 and a connecting frame 303 fixedly connected to the counterweight base 302. The connecting frame 303 is provided with an installation part 301. The weight of the counterweight base 302 provides downward pressure to the entire screen to prevent it from tipping over. When the screen is unfolded, its counterweight end will not be pulled, thus facilitating the unfolding of the screen.

[0035] Furthermore, each set of shielding plates 100 is also fixedly connected to a caster wheel 105 at its bottom, and a lead curtain 106 is fixedly connected to one side of the caster wheel 105 at the bottom of each set of shielding plates 100. This makes it easier to unfold the screen through the caster wheel 105, while the lead curtain 106 can fill the gap between the caster wheel 105 and the ground to prevent scattered radiation from escaping from the bottom, thus balancing mobility and protective integrity. Of course, for ease of operation, a push handle is also fixedly connected to the shielding plate 100 at the rear end.

[0036] Ideally, a limiting component 400 is fixedly connected to the shielding plate 100 at the tail end. Specifically, the limiting component 400 includes a mounting bracket 401, a screw 402, a friction disc 403, and a turntable 404. The mounting bracket 401 is fixedly connected to the shielding plate 100 near its bottom. The screw 402 is threadedly connected to the mounting bracket 401. The friction disc 403 is fixedly connected to the bottom end of the screw 402, and the turntable 404 is fixedly connected to the top end of the screw 402. By rotating the turntable 404, the screw 402 can drive the friction disc 403 to descend. When the friction disc 403 comes into contact with the ground, the friction between the friction disc 403 and the ground is used to stabilize the screen after it is unfolded or folded.

[0037] In an even better configuration, at least one set of shielding plates 100 between the head shielding plate 100 and the tail shielding plate 100 is provided with an observation port, and a lead glass 500 is fixedly connected inside the observation port. This ensures protection while allowing medical staff to observe the patient's condition in real time, thus improving the safety of the examination.
