Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a head shield for CT examination. Background Technology

[0002] CT (Computed Tomography) scan is a common medical imaging technique that uses X-rays and computer technology to create detailed images of the body's interior. CT scans can help doctors diagnose and assess various diseases, especially those that are difficult to detect with conventional X-rays or other examination methods, such as brain diseases, lung diseases, vascular diseases, heart diseases, and tumor screening. CT scans provide high-resolution, detailed images, helping doctors clearly see internal structures, and are particularly effective in assessing soft tissues, blood vessels, and bones. Furthermore, CT scans are fast, making them suitable for emergency situations and enabling rapid diagnosis.

[0003] However, CT scans require the use of X-rays, which involve radiation and can harm human cells. Currently, when hospitals perform radiological examinations on patients, patients wear lead caps to protect their heads. These caps cover the top of the head, eyes, and ears, but lack radiation protection for the face and neck. During the examination, the radiation can cause damage to the patient's face and neck. Therefore, a head shield for CT scans is proposed to solve the above problems. Utility Model Content

[0004] To address the aforementioned technical problems, a head shield for CT examinations is provided. This technical solution solves the problem of the lack of effective head protection for patients during CT examinations.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A head shield for CT scans includes a base, a face shield, and a neck shield. The face shield is positioned above the base, and the neck shield is positioned to the left of the face shield. The upper end of the neck shield is arc-shaped. The upper end of the base has a slot that engages with the bottom of the face shield. A connecting block is fixedly connected to one side of the base. The middle of the connecting block is rotatably connected to a rotating block. The end of the rotating block away from the connecting block is fixedly connected to the face shield. The face shield rotates along the connecting block via the rotating block. Two fixing blocks are fixedly connected to the end of the base away from the connecting block, and each fixing block has a slot at its upper end.

[0007] Preferably, a handle is fixedly connected to the upper end of the mask.

[0008] Preferably, the top of the mask has a notch, and a protective glass mounting frame is installed at the notch.

[0009] Preferably, a snap-fit ​​block is fixedly connected to the lower end of the neck shield, the snap-fit ​​block is correspondingly provided with a snap-fit ​​groove, and the neck shield is snapped into the snap-fit ​​groove through the snap-fit ​​block.

[0010] Preferably, a limiting block is fixedly connected to the side of the connecting block away from the neck shield, and the neck shield is used to limit the movement of the face shield when it is rotated to a certain angle.

[0011] Compared with the prior art, the advantages of this utility model are as follows: This protective cover is equipped with a face shield and a neck shield. The face shield is connected to the base through a rotating block. The patient can place their head in the fixed seat and then lower the face shield to protect their head. The structure is simple and convenient for medical staff to operate. The neck shield is detachable. When the patient's neck does not need to be examined, the neck shield can be quickly installed on the fixed seat through a snap-fit ​​block. The neck shield and the fixed seat work together to protect the patient's head and neck. In addition, when the patient's head is being examined, the neck shield can also be used alone to protect the neck, avoiding the harm to the patient caused by the lack of neck protection during CT examinations.

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] like Figure 1-2As shown, a head shield for CT examination includes a base 1, a face shield 2, and a neck shield 3. The face shield 2 is positioned above the base 1 and placed above the patient's head to protect the head and face. The neck shield 3 is positioned to the left of the face shield 2, with an arc-shaped upper end for easy placement around the patient's neck. A slot 11 is provided at the upper end of the base 1, which engages with the bottom of the face shield 2. This slot reduces the gap between the face shield 2 and the scanning bed when lowered, lowering the risk of radiation entering the face shield 2. A connecting block 12 is fixedly connected to one side of the base 1. The middle of the connecting block 12 is rotatably connected to a rotating block 23. The end of the rotating block 23 away from the connecting block 12 is fixedly connected to the face shield 2. The face shield 2 can be raised by rotating along the connecting block 12 via the rotating block 23, allowing the patient's head to be placed in the base 1 when lying down. The face shield 2 can be lowered before the examination for easy wearing. The upper end of the face shield 2 is fixedly connected... A handle 21 is provided to facilitate medical staff to lift or lower the mask 2. A limiting block 13 is fixedly connected to the side of the connecting block 12 away from the neck shield 3. The neck shield 3 is used to limit the rotation of the mask 2 to a certain angle to prevent the mask 2 from rotating too much and colliding with the scanning bed. Two fixing blocks 14 are fixedly connected to the end of the fixing base 1 away from the connecting block 12. Each fixing block 14 has a snap-fit ​​groove 15 at its upper end. A snap-fit ​​block 31 is fixedly connected to the lower end of the neck shield 3. The snap-fit ​​block 31 is set to correspond with the snap-fit ​​groove 15. The neck shield 3 is snapped into place by the snap-fit ​​block 31 and the snap-fit ​​groove 15. In this embodiment, the neck shield 3 is detachable. When there is no need to examine the patient's neck, the neck shield 3 can be quickly installed on the fixing base 1 through the snap-fit ​​block 31. The neck shield 3 and the fixing base 1 work together to protect the patient's head and neck. When the patient's head is being examined, the neck shield 3 can also be used alone to protect the neck.

[0020] In this embodiment, the top of the mask 2 has a notch, and a protective glass mounting frame 22 is installed at the notch. The protective glass mounting frame 22 is used to install radiation-proof glass. Medical staff can observe the patient's eyes through the glass to judge their condition or conduct necessary communication. The inside of the glass is filled with radiation-proof solution.

[0021] The principle of this utility model is as follows: The head shield is placed on the CT scanning bed. The face shield 2 is lifted by the handle 21. The patient lies on the scanning bed and places his head in the fixed seat 1. The medical staff lowers the face shield 2 and connects the neck shield 3 to the fixed seat 1 through the cooperation of the snap block 31 and the snap groove 15. This protects the patient's head and neck during CI examination. The neck shield 3 is detachable and can be used together with the face shield 2 or used alone. It has a wide range of applications, a simple structure, and can effectively protect the patient's head and neck from radiation.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
