Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, specifically relating to a CT auxiliary device. Background Technology

[0002] In modern medical diagnosis, CT scans, with their high resolution and rapid imaging capabilities, have become a crucial tool for disease diagnosis. To obtain accurate imaging results, patients must maintain a specific posture during the examination, which places stringent demands on the performance of support devices. Currently, most widely used support devices are neck braces to support the patient's neck, thereby maintaining head and neck stability and ensuring image quality. However, the skin on the patient's neck easily secretes oil, which adheres to the surface of the neck brace after prolonged use, leading to contamination. Traditional neck braces are difficult to clean, and repeated use can easily breed bacteria, posing a risk of cross-infection. Therefore, to address these issues, we propose a CT-assisted device.

[0003] The methods described in this section are not necessarily methods that had been previously conceived or adopted. Unless otherwise specified, no method described in this section should be assumed to be prior art simply because it is included in this section. Similarly, unless otherwise specified, the issues mentioned in this section should not be considered to be accepted in any prior art. Utility Model Content

[0004] The purpose of this invention is to provide a CT auxiliary device that solves the problem of difficult cleaning and easy bacterial growth leading to cross-infection on the surface of the neck brace by setting a detachable cover; at the same time, the reasonable design of the upper limb support and neck brace structure improves the patient's comfort during the CT examination and ensures the smooth progress of the examination.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A CT-assisted device includes an upper limb support, a neck support, a covering film, and a fixation component. The upper limb support is two in number, and the neck support is connected between the two upper limb supports. The covering film surrounds the neck support circumferentially, and the two free ends of the covering film are detachably fixed to the lower end of the neck support by the fixation component.

[0007] Furthermore, the lower end of the neck brace has an abutment groove extending along the axial direction of the neck brace. The fixing assembly includes an abutment member adapted to the shape of the abutment groove. The abutment member is tightly engaged within the abutment groove by frictional force to clamp the two free ends of the film within the abutment groove. This design allows the film to be securely installed on the neck brace, providing a protective layer for the neck brace, facilitating subsequent replacement of the film, and maintaining the hygiene of the device.

[0008] Furthermore, the abutment groove has a front groove wall and a rear groove wall facing each other, and the abutment member has a front abutment surface and a rear abutment surface facing each other. The free end on the front side is clamped between the front groove wall and the front abutment surface, and the free end on the rear side is clamped between the rear groove wall and the rear abutment surface. The double-sided clamping method enhances the stability of the film fixation, prevents the film from shifting during use, and ensures that it effectively blocks contaminants from contacting the neck brace.

[0009] Furthermore, both the front and rear abutting surfaces have several abutting protrusions. These abutting protrusions increase the friction with the free end of the coating, improving the fixing effect and making the coating less prone to loosening under various conditions.

[0010] Furthermore, several of the aforementioned abutment protrusions are spaced apart along the axial direction of the abutment member. This spaced-out design maximizes the contact area within a limited space while ensuring the structural strength of the abutment member, further enhancing the fixation of the coating.

[0011] Furthermore, the abutment protrusion is strip-shaped, with its length direction perpendicular to the axial direction of the abutment member. This strip-shaped design, perpendicular to the axial direction, increases friction while ensuring uniform force distribution on the abutment protrusion, thus improving the reliability of the fixation.

[0012] Furthermore, the edge of the abutment protrusion furthest from the abutment member is rounded, and the connection between the abutment protrusion and the abutment member is also rounded. This rounding prevents the abutment protrusion from scratching or tearing the film during installation and removal, thus extending the film's lifespan.

[0013] Furthermore, the lower end of the abutment has a receiving groove extending along the length of the abutment, and a push-pull crossbar extending forward and backward is fixedly connected in the receiving groove. There are multiple push-pull crossbars, which are spaced apart along the length of the abutment. This design facilitates the installation and removal of the abutment by medical staff, improving work efficiency, especially when there is a high patient flow.

[0014] Furthermore, the upper limb support and neck brace are integrally molded. This integral molding enhances the overall stability and strength of the device, improving its durability.

[0015] Furthermore, both the upper limb support and the neck brace are made of flexible materials. These flexible materials conform to the patient's body contours, providing comfortable support, relieving upper limb fatigue, avoiding neck pressure, and improving examination comfort.

[0016] The CT auxiliary device of this invention has many significant beneficial effects.

[0017] To enhance patient comfort, the upper limb and neck supports are integrally molded and made of flexible materials such as medical-grade silicone and polyurethane foam, which closely conform to the contours of the human body. The soft and elastic medical-grade silicone conforms to the limbs, distributing weight and relieving upper limb fatigue; the polyurethane foam evenly distributes pressure, avoiding neck compression, allowing patients to remain comfortable and stable throughout the examination.

[0018] In terms of hygiene and safety, the removable, film-covered neck brace can be easily replaced after each use. This effectively prevents neck oil from contaminating the neck brace, eliminates bacterial growth, significantly reduces the risk of cross-infection, and provides patients with safe and hygienic examination conditions.

[0019] In terms of ease of operation, the fixing component is cleverly designed. The abutment piece is tightly fixed to the film through abutment protrusions, which are spaced out along the axial direction in a strip shape to increase friction and achieve excellent fixing effect. The receiving groove at the lower end of the abutment piece is equipped with multiple spaced push-pull crossbars, which allow medical staff to easily and quickly install and remove the abutment piece, realize efficient film replacement, and improve work efficiency.

[0020] In terms of imaging quality optimization, the stable support structure helps patients maintain the correct position, reduces imaging deviation caused by limb movement, ensures clear and accurate imaging, and provides a strong basis for doctors to make accurate diagnoses.

[0021] In terms of device durability, the one-piece molded structure reduces wear on component connections, and the selected materials have excellent weather resistance and anti-aging properties, maintaining performance even after long-term use, effectively extending service life, reducing maintenance costs, and possessing extremely high practical value and promotional significance.

[0030] Upper limb support 1, neck support 2, abutment groove 21, film covering 3, free end 31, fixing component 4, abutment piece 41, abutment protrusion 413, receiving groove 414, push-pull crossbar 4141. Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] Reference Figures 1-6 As shown, the CT assist device in this embodiment includes an upper limb support 1, a neck brace 2, a covering 3, and a fixing component 4. Two upper limb supports 1 are positioned on either side of the neck brace 2, with the neck brace 2 connected between the two upper limb supports 1. The upper limb supports 1 support the patient's upper limbs, effectively relieving upper limb fatigue and helping the patient maintain a stable position during the examination. The covering 3 surrounds the neck brace 2, and its two free ends 31 are detachably fixed to the lower end of the neck brace 2 via the fixing component 4, facilitating replacement after each use and ensuring hygiene.

[0033] In this embodiment, the neck brace 2 has an axially extending abutment groove 21 at its lower end. The fixing assembly 4 includes an abutment member 41 adapted to the abutment groove 21. The abutment member 41 is tightly engaged in the abutment groove 21 by friction, thereby clamping the free end 31 of the film 3. This structure is simple and practical, facilitating quick replacement of the film 3. The abutment groove 21 has a front groove wall and a rear groove wall with opposite front and rear sides, and the abutment member 41 has a front abutment surface and a rear abutment surface accordingly. The front free end 31 is clamped between the front groove wall and the front abutment surface, and the rear free end 31 is clamped between the rear groove wall and the rear abutment surface, further stabilizing the fixing of the film 3.

[0034] In this embodiment, both the front and rear abutting surfaces are provided with a plurality of abutting protrusions 413. These protrusions are spaced apart along the axial direction of the abutting member 41 and are strip-shaped, with their length direction perpendicular to the axial direction of the abutting member 41. This increases the friction with the free end 31 of the coating 3, resulting in a better fixing effect. The edge of the abutting protrusion 413 away from the abutting member 41 and the connection point with the abutting member 41 are rounded to prevent damage to the coating 3 during installation or disassembly.

[0035] In this embodiment, the lower end of the abutment 41 has a receiving groove 414 extending along the length direction. Multiple push-pull crossbars 4141 extending along the front-back direction and spaced apart are fixed in the receiving groove 414, which facilitates the installation and disassembly of the abutment 41 by medical staff.

[0036] In this embodiment, the upper limb support 1 and neck support 2 are integrally molded, enhancing the overall stability and strength of the device. Furthermore, both the upper limb support 1 and neck support 2 are made of flexible materials. Common material choices include medical-grade silicone, which is soft and elastic, non-irritating to human skin, conforms well to the contours of the patient's upper limbs and neck, providing comfortable support, and can be used long-term in medical environments. Polyurethane foam can also be used, which has excellent cushioning properties, evenly distributing body pressure, reducing localized pressure on the patient, and is lightweight, without placing an extra burden on the patient. This material also possesses certain antibacterial properties, helping to maintain the cleanliness and hygiene of the device. The flexible upper limb support 1 conforms to the shape of the patient's upper limb, providing comfortable support and reducing patient discomfort; the flexible neck support 2 conforms to the curve of the neck, avoiding pressure on the neck, greatly improving patient comfort during the examination process.

[0037] Installation process: First, wrap the film 3 around the neck brace 2, positioning the two free ends 31 at the abutment groove 21 at the lower end of the neck brace 2. Next, align the abutment member 41 with the abutment groove 21 and push the push-pull crossbar 4141 on the abutment member 41 to engage the abutment member 41 with the abutment groove 21. During this process, the abutment protrusions 413 on the front and rear abutment surfaces of the abutment member 41 will make close contact with the two free ends 31 of the film 3, thereby firmly fixing the film 3 to the neck brace 2.

[0038] Usage: During a CT scan, the patient places their neck on the neck brace 2 and their upper limbs on the upper limb brace 1. Both the upper limb brace 1 and neck brace 2 are made of flexible material, conforming well to the body and providing comfortable support. The neck brace 2 stably supports the neck, ensuring correct patient positioning and improving image quality. Simultaneously, the covering 3 around the neck brace 2 prevents neck oil from contaminating it.

[0039] Disassembly and Replacement Process: After the inspection, medical staff pull the push-pull crossbar 4141 in the receiving groove 414 at the lower end of the abutment 41 to remove the abutment 41, thus easily removing the used cover 3. A new cover 3 is then installed, and the device is reinstalled following the above installation steps for the next patient. This effectively avoids cross-infection problems caused by the difficulty in cleaning the neck brace 2, ensuring the hygiene and safety of the CT auxiliary device.

[0040] In summary, the CT auxiliary device provided by this utility model is ingeniously designed in terms of structure. It consists of an upper limb support, a neck brace, a diaphragm, and a fixation component. The upper limb support and neck brace are integrally molded using a flexible material such as medical-grade silicone or polyurethane foam, which can closely conform to the contours of the human body, relieve upper limb fatigue, avoid neck pressure, and significantly improve comfort during examination. The fixation component engages with a contact piece via an abutment groove at the lower end of the neck brace. The abutment protrusions on the contact piece increase friction, firmly fixing the free end of the diaphragm and facilitating diaphragm replacement.

[0041] In terms of usage, the installation and disassembly process is simple, and medical staff can easily complete the operation by using the push-pull crossbar. When in use, the device not only ensures that the patient maintains a stable position and improves imaging quality, but also effectively solves the problems of traditional neck braces being difficult to clean and prone to bacterial growth and cross-infection through the removable cover, ensuring hygiene and safety, and has high practical value and promotion significance.
