Description
Technical Field
[0001] This utility model relates to a foldable X-ray shielding protection mechanism for mobile CT, belonging to the field of X-ray shielding technology for mobile CT. Background Technology
[0002] Traditional CT scanners are limited by X-ray shielding requirements and must operate within a dedicated lead-lined enclosure. This enclosure, constructed with high-density shielding materials, is a completely sealed space that effectively prevents radiation leakage. However, this also confines it to a fixed environment, requiring patients to move to a designated area for scanning. Mobile CT scanners, on the other hand, are designed to overcome these limitations, adapting to diverse medical scenarios such as emergency care, ICU bedside care, and general wards. They eliminate the need to transfer critically ill or post-operative patients with limited mobility, significantly reducing response time – this is the most crucial difference between mobile and traditional CT scanners.
[0003] To meet its mobile requirements, mobile CT scanners have integrated X-ray shielding systems into the gantry, effectively reducing radiation leakage from the main structure. However, the scanning aperture, as a necessary passage for patients, needs to maintain dynamic open space to accommodate the movement of the scanning bed; therefore, basic protection is achieved only through lead curtains. While lead curtains can fit snugly against the edges of the scanning aperture, individual patient differences (such as limb positioning angles, torso contours, and clothing thickness) make it difficult to achieve a complete seal, inevitably creating tiny gaps. In the absence of lead-lined shielding in general wards, these leaking, scattered rays can directly diffuse into the surrounding space, posing a radiation exposure risk not only to medical staff operating at close range but also potentially affecting the health of other patients and caregivers in the same ward, creating a radiation contamination hazard that urgently needs to be addressed. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a foldable X-ray shielding mechanism for mobile CT scanners, which shields the radiation leaking from the CT scanning port and prevents the mobile CT scanner from causing radiation pollution to the surrounding environment.
[0005] The technical solution of this utility model is: a foldable X-ray shielding protection mechanism for mobile CT, including a retractable shielding structure disposed on both sides of the front and rear of the scanning port of the self-shielding mobile CT machine; The retractable shielding structure includes a retractable front shielding compartment located in front of the scanning port. The retractable front shielding compartment is equipped with a foldable side door. The retractable front shielding compartment and the CT machine housing in front of the scanning port form a closed structure. The retractable shielding structure also includes a retractable rear shielding compartment located behind the scanning aperture. The retractable rear shielding compartment can be stretched and expanded during scanning to form a closed structure with the rear side of the scanning aperture.
[0006] The connection between the foldable side door and the retractable front shielding compartment is made of zipper or Velcro to enable quick opening and closing of the foldable side door. The bottom of both the foldable side door and the retractable front shielding compartment is equipped with several rollers a for assisting telescopic movement.
[0007] The retractable rear shielding compartment includes a flexible tungsten silicone shielding material and supporting rings. The flexible tungsten silicone shielding material forms a retractable cylindrical structure under the support of several parallel supporting rings. The bottom of several supporting rings is connected to a telescopic support rod. The end of the telescopic support rod is provided with a pin. The CT machine housing is provided with a slot. The telescopic support rod and the CT machine housing are connected by the pin and the slot to achieve a quick and detachable connection.
[0008] The retractable rear shielding chamber is provided with several pins on its circumferential side, and the CT machine housing is provided with several slots. The retractable rear shielding chamber and the CT machine housing are connected by the pins and slots to achieve quick and detachable connection. The slots all face upwards.
[0009] The retractable front shielding compartment includes a flexible tungsten silicone shielding material and a metal bracket. The flexible tungsten silicone shielding material forms a retractable cuboid structure under the support of several parallel metal brackets. The bottom of the metal brackets is provided with several rollers b for convenient retractable movement.
[0010] The foldable side door includes a flexible tungsten silicone shielding material and metal rods. The flexible tungsten silicone shielding material forms a retractable rectangular structure under the support of several parallel metal rods, and the rollers a are installed at the bottom of the metal rods.
[0011] This shielding and protection structure also includes auxiliary functional systems, which include an internal lighting system and a monitoring system.
[0012] The internal lighting system is a ring-shaped light strip installed in the retractable front shielding chamber. The monitoring system includes cameras installed in the retractable front shielding chamber and the retractable rear shielding chamber, respectively, for real-time observation of the patient's status during the scanning process.
[0013] The ring-shaped light strip is located on the CT scanner housing on the front side of the scanning port.
[0014] The beneficial effects of this utility model include: 1. Enhanced Safety Protection: This retractable shielding structure uses flexible tungsten silicone shielding material, which can effectively block radiation leakage during mobile CT scans, preventing radiation from polluting the surrounding environment. At the same time, it creates a comprehensive protective barrier for medical staff assisting in close-range operations, significantly reducing the risk of long-term occupational exposure and making the treatment environment more compliant with radiation safety standards.
[0015] 2. Improved operational efficiency: The retractable shielded compartment is designed as an independent mobile unit, equipped with silent casters at the bottom, allowing medical staff to move it by a single person; and it adopts a quick-release snap-fit connection with the CT machine, improving disassembly and assembly efficiency, significantly reducing manpower consumption, saving equipment preparation time, and enhancing the convenience of clinical operation.
[0016] 3. Optimization of clinical treatment: With the help of this retractable structure, medical staff no longer need to transfer critically ill or post-operative patients who are difficult to move to a dedicated CT room. They can quickly carry out scanning examinations in ordinary wards. This not only reduces the risk of fluctuations in the patient's condition during the transfer process, but also shortens the waiting time for examinations, thus securing a valuable window of opportunity for emergency and critically ill patients and effectively improving the overall treatment efficiency.
