Description

Technical Field

[0001] This utility model relates to the field of radiation protection technology for CT imaging, specifically a radiation protection device for CT angiography. Background Technology

[0002] CT angiography, also known as CT angiography, is a common medical imaging technique. It combines enhanced CT technology with thin-slice, large-area, and rapid scanning, and through appropriate image post-processing, clearly displays the details of blood vessels throughout the body. During CT angiography, the equipment generates a significant amount of radiation. To reduce the harm caused by radiation to unscanned areas of the patient, radiation protection devices for CT angiography are generally required.

[0003] Existing radiation protection devices consist of a flexible radiation shield made up of several arc-shaped strips installed on a CT examination table. However, due to the arc shape of the flexible shield, gaps exist between the shield and the patient's body, allowing radiation to leak through these gaps and still potentially harming unscanned areas of the patient. Therefore, those skilled in the art have provided a radiation protection device for CT angiography to address the problems mentioned in the background section. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a radiation protection device for CT angiography in radiology. This device solves the problem that existing radiation protection devices consist of a flexible radiation shielding cover made up of several arc-shaped strips installed on the CT examination bed. However, because the flexible radiation shielding cover is arc-shaped, there are gaps between the flexible radiation shielding cover and the patient's body, causing radiation to leak from the gaps and still harm the unscanned areas of the patient.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a radiation protection device for CT angiography, comprising a CT examination bed, a first support, and a second support. The first support is disposed on the upper side of the CT examination bed, and the second support is disposed on one side of the first support. First sliding grooves are provided on both sides of the CT examination bed. A second sliding groove is provided on one side of the CT examination bed below one end of the first sliding groove, and a third sliding groove is provided on the other side of the CT examination bed below the other end of the first sliding groove. A connector is provided in the second sliding groove. A plug is inserted into one end of the second support. A limit rod is provided on the second support. A radiation protection elastic airbag is installed on the first support. An air inlet pipe is installed on one side of the first support. An air pump unit is installed inside the CT examination bed, and a telescopic air pipe is connected to the air pump unit.

[0008] Preferably, the second bracket is rotatably connected to the connector, the connector is slidably engaged with the second slide groove, the insert is inserted into the third slide groove, and the insert has damping characteristics when inserted into the third slide groove, so that the moved second bracket can be positioned by the insert.

[0009] Preferably, the limiting rod is slidably inserted into the second bracket, and the limiting rod inside the second bracket comes into contact with the patient's body surface under its own weight, thereby forming a protective net to prevent the radiation-proof elastic airbag from inflating.

[0010] Preferably, the radiation-proof elastic airbag is made of rubber-based radiation-proof material. By adding radiation-proof agents, such as lead powder, barium powder or other high-density substances, its radiation-proof ability is enhanced. These materials maintain the original elasticity of rubber while also having a certain radiation-proof effect.

[0011] Preferably, the number of telescopic air tubes corresponds to the number of first supports. The telescopic air tubes are connected to the radiation-proof elastic airbags through air inlets. The air pump unit inflates the radiation-proof elastic airbags through the telescopic air tubes, causing them to expand and contact the patient's body surface, thereby expanding and filling the gap between the first supports and the patient.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a radiation protection device for CT angiography, which has the following beneficial effects:

[0014] The radiation protection device for CT angiography in this invention consists of a CT examination table, a first support, a radiation-proof elastic airbag, a second support, and limiting rods. After the patient lies on the CT examination table, the first support is slid, with the sliding position determined by the staff. Then, the second support is moved to both sides of the area to be scanned. The limiting rods inside the second support, under their own weight, come into contact with the patient's skin, forming a protective barrier against the expansion of the radiation-proof elastic airbag. Once the second support is fixed, the air pump unit is activated, inflating the radiation-proof elastic airbag through a telescopic air tube. This inflates the airbag and makes it contact the patient's skin, filling the gap between the first support and the patient. This prevents radiation from propagating through the gap during the examination, reducing the risk of damage to unscanned areas. Attached Figure Description

The insert 9 can be used to position the moved second support 6. The limiting rod 7 is slidably inserted into the second support 6, and the limiting rod 7 inside the second support 6 contacts and adheres to the patient's body surface under its own weight, thereby forming a protective net to prevent the radiation-proof elastic airbag 5 from inflating. The radiation-proof elastic airbag 5 is made of rubber. Made of basic radiation-shielding material, its radiation-shielding ability is enhanced by adding radiation-shielding agents such as lead powder, barium powder or other high-density substances. These materials maintain the original elasticity of rubber while also having a certain radiation-shielding effect. The number of telescopic air tubes 3 corresponds to the number of first supports 4. The telescopic air tubes 3 are connected to the radiation-shielding elastic airbag 5 through the air inlet pipe 401. The air pump unit 2 inflates the radiation-shielding elastic airbag 5 through the telescopic air tubes 3, so that it expands and contacts the patient's body surface, thereby expanding and filling the gap between the first support 4 and the patient.

[0023] The radiation protection device for CT angiography in this utility model consists of a CT examination table 1, a first support 4, a radiation protection elastic airbag 5, a second support 6, and a limiting rod 7. First sliding grooves 101 are symmetrically provided on both sides of the CT examination table 1. A second sliding groove 102 is provided on one side of the CT examination table 1 below the first sliding groove 101, and a third sliding groove 103 is provided on the other side of the CT examination table 1 below the first sliding groove 101.

The radiation protection elastic airbag 5 is made of rubber-based radiation protection material. By adding radiation protection agents, such as lead powder, barium powder or other high-density substances, its radiation protection ability is enhanced. These materials maintain the original elasticity of rubber and also have a certain radiation protection effect.

[0025] After the patient lies on the CT examination table 1, the first support 4 is slid, with the sliding positions determined by the staff. Then, the second support 6 is moved, sliding to both sides of the area to be imaged. Figure 2 As shown, the second support 6 is then positioned by the insert block 9 to prevent it from moving. The limiting rod 7 inside the second support 6 contacts and adheres to the patient's body surface under its own weight, thus forming a protective net to prevent the radiation-proof elastic airbag 5 from inflating. After the second support 6 is fixed, the air pump unit 2 is activated, and the air pump unit 2 inflates the radiation-proof elastic airbag 5 through the telescopic air tube 3, causing it to inflate and contact the patient's body surface, thereby expanding and filling the gap between the first support 4 and the patient. This prevents radiation from spreading through the gap during the patient's examination and reduces the risk of damage to the unscanned areas of the patient.
