Embodiment 1

[0023] Such as figure 1 As shown, a device for preventing the neck from being irradiated is installed on the bed of a CT machine. The device for preventing the neck from being irradiated includes a base 1 and a pair of lead-made arc shields 2 with opposite concave surfaces. The arc-shaped shields 2 are symmetrically arranged on the base 1 and are slidably connected with the base 1. The diameter of one arc-shaped shield 2 is slightly larger than that of the other, so as to ensure that the tops of the two arc-shaped shields 2 overlap rather than offset when they are closed. The base 1 is provided with a shield closing mechanism, which includes a pair of shield seats 3 and two pairs of thrust springs 4, the shield seats 3 are symmetrically fixed on the base 1, and the shield seats 3 are provided with a shield Cavity 14, arc shield 2 is positioned at shield chamber 14, and thrust spring 4 is connected between arc shield 2 and shield seat 3, and each arc shield 2 corresponds to two...

Embodiment 2

[0026] Such as figure 2 , image 3 As shown, the shield closing mechanism includes a shield driving motor 7 and a shield driving screw 8, the base 1 is an overhead structure with supporting feet, the shield driving motor 7 is fixedly installed on the bottom of the base 1, and the shield driving screw 8 rotates Connected in the guide groove 5 and threadedly connected with the slider 6, the shield driving screw 8 is connected with the output end of the shield driving motor 7, and the shield driving screw 8 is provided with a positive thread section and a reverse thread section, two arcs The slide block 6 of shaped shield 2 is on the positive thread segment and the reverse thread segment. The output end of the shield driving motor 7 is keyed to the driving gear, and the end of the shield driving screw 8 is keyed to the driven gear. The bottom of the base 1 has a passage leading to the guide groove 5, and the driven gear meshes with the driving gear through the passage. . The ...

Embodiment 3

[0029] The 7 output ends of the shield driving motor are keyed to connect the driving pulley, and the 8 ends of the shield driving screw rod are keyed to connect the driven pulley, and the driving pulley and the driven pulley are connected by a timing belt. All the other are with embodiment 2.

Abstract

The invention discloses a device for preventing the neck from being irradiated. The device is arranged on a bed surface of a CT machine. The device for preventing the neck from being irradiated comprises a base and a pair of arc protective covers with opposite concave faces, the arc protective covers are symmetrically arranged on the base and slidably connected with the base, and a protective cover folding mechanism is arranged on the base. According to the arc protective cover, the protective cover makes contact with the neck from the side face, regulative control can be performed through theprotective cover folding mechanism, no heavy pressure is likely to be formed on the neck, and therefore use is more comfortable and convenient. By controlling the protective cover folding mechanism,the folding degree of the arc protective cover can be different due to different neck circumferences of patients, and therefore the good generality is achieved. Cross infection can be avoided, and potential safety hazards are eliminated.

Description

technical field [0001] The present invention relates to a medical device and more particularly to a device for protecting the neck from radiation. Background technique [0002] With the development of modern medicine, CT machines are becoming more and more popular. The probability of the human body receiving CT scan is also getting higher and higher and there is a trend of continuing to increase. CT examination plays an important role in the diagnosis and treatment of diseases, and is a medical technology that is easily accepted by people. However, CT scans produce X-rays, and repeated exposure to X-rays can be harmful to the body. For some special populations, such as infants and young children, patients with aplastic anemia, etc., special attention should be paid to the damage of radiation to the human body. As for adults, as mentioned above, with the popularization of CT, the probability of being exposed to CT scans every year for reasons such as physical examination o...
