Description

Technical Field

[0001] This utility model relates to the field of protective screen technology, and in particular to a convenient protective screen. Background Technology

[0002] D-SPECT (Digital SPECT, or Cadmium Zinc Telluride SPECT for the Heart) is an advanced nuclear medicine imaging device that uses a cadmium zinc telluride semiconductor detector to capture gamma rays emitted by a radioactive tracer. Compared to traditional detectors based on scintillation crystals (such as NaI(Tl)), the CZT detector offers higher spatial resolution, better energy resolution, and faster data acquisition speed, making D-SPECT outstanding for cardiac imaging.

[0003] When performing nuclear medicine examinations using a D-SPECT cardiac-specific machine, a protective screen is required between the patient and the nuclear medicine technician to reduce radiation damage to the technician. However, existing protective screens are usually equipped with casters for movement, resulting in a large gap between the screen and the ground. In addition, existing protective screens are usually a single rectangular panel with a fixed observation window, which makes it difficult for nuclear medicine technicians to position the patient in a suitable position, thus hindering the nuclear medicine examination. Utility Model Content

[0004] The present invention aims to provide a convenient protective screen to solve the problem that the protective screen of the existing D-SPECT cardiac machine has a protective gap and is not convenient for nuclear medicine technicians to adjust the patient's position.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The basic technical solution provided by this utility model is as follows: a convenient protective screen, including a base, a protective screen one fixedly connected to the upper end of the base, the protective screen one having an operation window, a protective screen two rotatably connected to the upper end of the protective screen one via a hinge, the protective screen two having an observation port with a transparent window, the protective screen two rotatably connected to an adjusting rod, the protective screen one rotatably connected to an adjusting sleeve slidably connected to the adjusting rod, the adjusting sleeve connected to a positioning seat, the positioning seat slidably connected to a positioning rod, a pressure spring provided between the positioning rod and the positioning seat, the adjusting rod having multiple sets of positioning holes, the positioning rod slidably connected to the positioning holes; multiple sets of universal wheels connected to the lower end of the base, a protective screen three slidably connected to the base, the protective screen three having a threaded sleeve, and a threaded rod rotatably connected to the base via a threaded connection to the threaded sleeve.

[0007] The principle of the basic technical solution: The casters are used to move the device and are equipped with brakes for easy fixing. Rotating the threaded rod, through the threaded engagement between the threaded rod and the threaded sleeve, controls the downward movement of the protective screen three until it fits against the base plate. The protective screen one separates the patient from the nuclear medicine technicians. The patient's field of vision is obtained through the observation port, and the relevant operations for nuclear medicine examinations are performed through the operation window. When it is necessary to adjust the angle of the protective screen two, pulling the positioning rod disengages it from the positioning hole, allowing the protective screen three to rotate. After rotating a certain angle, the positioning rod is pushed into the positioning hole by the elastic force of the pressure spring, thus keeping the combined length of the adjusting rod and the adjusting sleeve fixed. Based on the stability of a triangle, the protective screen three also remains fixed at this time.

[0008] The beneficial effects of the basic technical solution are as follows: the vertical movement of the protective screen three can be controlled by rotating the threaded rod, which can achieve the effect of blocking radiation without affecting the movement of the device. It has good protection effect and high convenience, which is conducive to use. Through the cooperation of the positioning rod and the positioning hole, the combined length of the adjusting rod and the adjusting sleeve can be changed. The protective screen two can be adjusted to a suitable angle according to the height of nuclear medicine technicians and the field of vision of different patients. It has high adaptability and solves the problem that the protective screen of the existing D-SPECT cardiac special machine has a protective gap and is not convenient for nuclear medicine technicians to adjust the patient's position.

[0009] Preferably, a baffle is fixedly connected to the upper end of the protective screen.

[0010] With the above setup, there is a small gap at the connection between protective screen one and protective screen two, so a baffle is installed to improve its protective capability.

[0011] Preferably, the transparent window is made of lead glass.

[0012] With the above-mentioned design, lead glass has a strong absorption capacity for harmful radiation such as X-rays and gamma rays, which helps to improve its protective capabilities.

[0013] Preferably, the operating window is connected to a protective curtain, and the protective curtain is made of lead rubber.

[0014] Through the above-mentioned setup, the protective curtain effectively reduces the radiation exposure to nuclear medicine technicians during the inspection process, while having minimal impact on their operations and ensuring high reliability.

[0015] Preferably, handles are fixedly connected to both sides of the protective screen.

[0016] With the above-mentioned design, the device can be moved by a handle, and the handle located at the patient end can be grasped by the patient to provide assistance, thus improving the convenience and reliability of the device.

[0017] Preferably, both sides of the protective screen are fixedly connected to reinforcing plates, and the reinforcing plates are fixedly connected to the base.

[0018] The above-mentioned reinforcement plate helps to improve the structural strength of the device and extend its service life. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0025] like Figures 1 to 4As shown, a convenient protective screen includes a base 1, with reinforcing plates 19 fixedly connected to both sides of the protective screen 2. The reinforcing plates are fixedly connected to the base 1. The protective screen 2 is fixedly connected to the upper end of the base 1. Handles 15 are fixedly connected to both sides of the protective screen 2. The protective screen 2 has an operation window 16, and a protective curtain 17 is connected to the operation window 16. The protective curtain 17 is made of lead rubber. The upper end of the protective screen 2 is rotatably connected to a second protective screen 3 via a hinge. A baffle 18 is fixedly connected to the upper end of the protective screen 2. The second protective screen 3 has an observation port 4, which is equipped with a transparent window. The window is made of lead glass. Protective screen 2 3 is rotatably connected to an adjusting rod 5. Protective screen 1 2 is rotatably connected to an adjusting sleeve 7 that is slidably connected to the adjusting rod 5. The adjusting sleeve 7 is connected to a positioning seat 8. The positioning seat 8 is slidably connected to a positioning rod 9. A pressure spring 10 is provided between the positioning rod 9 and the positioning seat 8. The adjusting rod 5 has multiple sets of positioning holes 6. The positioning rod 9 is slidably connected to the positioning holes 6. The lower end of the base 1 is connected to multiple sets of universal wheels 14. The base 1 is slidably connected to a protective screen 3 11. The protective screen 3 11 has a threaded sleeve 12. The base 1 is rotatably connected to a threaded rod 13 that is threadedly connected to the threaded sleeve 12.

[0026] The specific implementation process is as follows:

[0027] When using this new device, firstly, move it to a suitable position next to the cardiac machine using the universal wheels 14 and fix it with the brakes. Then, rotate the threaded rod 13 so that it drives the protective screen 11 downwards through the threaded sleeve 12 until it is in contact with the ground. Next, pull the positioning rod 9 to disengage it from the positioning hole 6 and continue to apply force to keep it in the disengaged state. Then, rotate the protective screen 3 to change its angle. During this process, the adjusting rod 5 and the adjusting sleeve 7 slide relative to each other. The nuclear medicine technician, based on their height and field of vision, rotates it to a suitable angle and then releases the positioning rod 9. The positioning rod 9 receives the elastic force of the pressure spring 10 and slides into the positioning hole 6, so that the adjusting rod 5 and the adjusting sleeve 7 remain fixed. The combination of the adjusting rod 5 and the adjusting sleeve 7, the protective screen 1 and the protective screen 2 form a triangle, thus keeping the protective screen 2 fixed. The nuclear medicine technician can then clearly obtain the patient's field of vision through the observation port 4. The nuclear medicine technician can then reach to the patient's end through the operation window 16 to perform the corresponding operations.
