Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a head fixation sponge pad for CT neck scans. Background Technology

[0002] During CT neck scans, beam hardening artifacts often occur, which can severely affect image quality and interfere with doctors' accurate assessment of the patient's condition.

[0003] Currently, adding a specific medium (such as saline) to the scanning area can effectively reduce the generation of beam hardening artifacts. However, in actual operation, when the saline bag is placed in the gap between the CT table and the head frame, it is easy for the saline bag to fall off due to the lack of an effective fixing and support structure. This prevents it from stably reducing artifacts, resulting in reduced scanning efficiency and difficulty in obtaining ideal scan images. Therefore, a device that can stably fix the saline bag while simultaneously securing the head is needed to solve the above problems. Summary of the Invention

[0004] This utility model mainly provides a head fixation sponge pad for CT neck scans that can stably fix a saline bag and simultaneously fix the head.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a head fixation sponge pad for CT neck scanning, comprising: a sponge pad body, a head recess being provided at the top of the sponge pad body, fixing straps being fixed at equal intervals on both sides of the inner wall of the head recess, and saline bag cavities being provided inside the sponge pad body and on both sides of the head recess.

[0006] Preferably, an anti-slip pad is fixedly connected to the bottom of the main body of the sponge pad. With the above arrangement, the anti-slip pad at the bottom of the main body of the sponge pad can increase the friction between the sponge pad and the CT bed surface, prevent the sponge pad from sliding on the CT bed, and further improve the stability of the device.

[0007] Preferably, a first Velcro strap is fixedly connected to the surface of one side of the fixing strap, and a second Velcro strap is fixedly connected to the surface of the other side of the fixing strap. With the above arrangement, the head can be fixed according to the size of the patient's head, ensuring that the patient's head remains stable during the scanning process.

[0008] Preferably, each saline bag cavity has a square hole at the top, and a zipper is embedded and installed inside each square hole. This design can seal the saline bag inside the saline bag cavity and prevent the saline bag from shifting during scanning.

[0009] Preferably, the headrest includes two symmetrically arranged arc-shaped headrest protrusions. The arc-shaped headrest protrusions in the headrest are made of sponge material. With the above arrangement, it can fit the contour of the patient's head and provide comfortable support for the patient's head.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting a saline bag cavity on the left side of the main body of the sponge pad and fixing it with a sealing zipper, the saline bag can be stably placed in the CT neck scanning area, effectively reducing wire hardening artifacts and improving the quality of the scanned image.

[0011] 2. In this utility model, the design of the head fixation structure includes an arc-shaped headrest protrusion and a head fixation strap, which can provide a comfortable and stable fixation for the patient's head, prevent the patient's head from moving during the scanning process, and ensure the accuracy and effectiveness of the scan.

[0012] 3. In this utility model, the anti-slip layer at the bottom of the main body of the sponge pad increases the friction between it and the CT bed, preventing the sponge pad from sliding, further ensuring the stability of the saline bag and the patient's head, and improving the practicality and reliability of the device.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Please see Figures 1-3 This utility model provides a technical solution: a head fixation sponge pad for CT neck scanning, comprising: a sponge pad body 1, a head groove 3 is provided on the top of the sponge pad body 1, and fixing straps 4 are fixed at equal intervals on the inner walls of both sides of the head groove 3, and saline bag cavities 7 are provided inside the sponge pad body 1 and on both sides of the head groove 3.

[0018] like Figure 1 As shown, an anti-slip pad 2 is fixedly connected to the bottom of the main body 1 of the sponge pad. Through the above-mentioned arrangement, the anti-slip pad 2 at the bottom of the main body 1 of the sponge pad can increase the friction between the sponge pad and the CT bed surface, prevent the sponge pad from sliding on the CT bed, and further improve the stability of the device.

[0019] like Figure 3 As shown, one side of the fixing strap 4 is fixedly connected to the surface of the first Velcro 5, and the other side of the fixing strap 4 is fixedly connected to the surface of the second Velcro 6. With the above settings, the head can be fixed according to the size of the patient's head, ensuring that the patient's head remains stable during the scanning process.

[0020] like Figure 1 As shown, each saline bag cavity 7 has a square hole 8 at the top, and a zipper 9 is embedded and installed inside each square hole 8. Through the above setting, the saline bag can be sealed in the saline bag cavity 7 to prevent the saline bag from shifting during the scanning process.

[0021] like Figure 2 As shown, the head groove 3 includes two symmetrically arranged arc-shaped headrest protrusions. The arc-shaped headrest protrusions in the head groove 3 are made of sponge material. Through the above arrangement, it can fit the contour of the patient's head and provide comfortable support for the patient's head.

[0022] The device's usage and working principle are as follows: During use, place the sponge pad body 1 in the gap between the CT bed and the head frame. Because the shape of the sponge pad body 1 fits the gap, it fills the space tightly, ensuring stable placement. Place the saline bag into the saline bag cavity 7 on the left side of the sponge pad body 1, and pull the sealing zipper 9 to seal and secure the saline bag. The patient lies on the CT bed with their head placed inside the head recess 3. The patient's head can then be secured with the fixation strap 4. At this time, the saline bag is located in the CT neck scanning area, effectively reducing beam hardening artifacts during the scan, while simultaneously stabilizing the patient's head, thus obtaining high-quality CT neck scan images.
