Description

Technical Field

[0001] This utility model relates to the field of MRI scan-aid technology, specifically an MRI scan positioning patch containing cod liver oil. Background Technology

[0002] Magnetic resonance imaging (MRI) is a commonly used non-invasive imaging technique in clinical medicine, offering advantages such as high soft tissue resolution, no ionizing radiation, and flexible imaging planes. It is widely used in the diagnosis of diseases of the nervous system, resectable anatomical systems, cardiovascular systems, and tumors. MRI primarily works by applying an external magnetic field to induce nuclear signals in hydrogen-rich tissues within the body. These signals are then acquired and processed to create high-resolution anatomical and functional images.

[0003] In current clinical MRI scans, especially for lesions in soft tissue areas such as the limbs, small joints, or abdominal wall, the location of lesions is often difficult to determine by sight or touch. Because their imaging characteristics are similar to surrounding tissues, precise localization of the lesion is a frequent challenge during MRI procedures. Particularly when the patient's lesion location cannot be accurately described, clinicians often resort to a "blind scan" approach, relying on extensive scanning to locate the lesion. This not only reduces scanning efficiency but also increases scan time, causing inconvenience, unnecessary waiting, and anxiety for the patient. Furthermore, the significantly increased reliance on localization methods can lead to misinterpretation or missed diagnoses, affecting the final diagnostic outcome.

[0004] However, one current clinical approach to address this issue is using cod liver oil as a surface marker in MRI scans. The physical properties of cod liver oil produce a strong signal in MRI images, aiding in the marking of lesions. The commonly used method involves securing cod liver oil capsules with tape, which is not only cumbersome and prone to fluid loss or marker displacement, but also inconvenient for patients as the tape is directly adhered to the skin. Especially during prolonged or repeated scans, tape fixation can cause skin discomfort and allergic reactions, impacting the patient experience. Therefore, there is an urgent need for a high-precision, accurate, and comfortable MRI surface marking method to improve the clinical efficiency and accuracy of MRI scans.

[0005] To address this, drawing on years of clinical experience, we have designed a product for marking lesions on the body surface for MRI. The product is primarily a patch that serves as a carrier for cod liver oil, allowing for easy application to the patient for MRI scanning. It aims to simplify the marking process for lesions on the body surface and addresses the stability and comfort issues inherent in traditional methods through structural design. This innovative patch uses soft, damage-resistant materials to evenly distribute the cod liver oil solution within the cavity, ensuring stable positioning of the marker during scanning while avoiding interference with image quality, thus improving the overall efficiency of MRI examinations. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0019] Please see Figure 1-3 This embodiment provides an MRI scan positioning dressing containing cod liver oil, comprising an upper transparent film 1 and a lower transparent film 2, with a cod liver oil layer 3 disposed between the upper transparent film 1 and the lower transparent film 2. The sides of the upper transparent film 1 and the lower transparent film 2 are sealed together by a heat-sealing layer 4. As a conventional arrangement familiar to those skilled in the art, the heat-sealing layer 4 can be formed by heat-sealing the two films using a heat-sealing machine. Furthermore, as a conventional choice, the upper transparent film 1 and the lower transparent film 2 can preferably be made of medical transparent PU film, but other conventional films can also be used as needed; this application will not elaborate on the limitations.

[0020] In addition, to ensure the stability of the patch after it is applied to the patient's skin, an adhesive layer 5 is provided on the underside of the heat-sealed layer 4. The material of the adhesive layer 5 should be common knowledge familiar to those skilled in the art, and medical pressure-sensitive adhesive is preferred. As a standard design, an anti-adhesive tape 6 should also be provided on the surface of the adhesive layer 5, which can be removed during use. Example 2

[0021] Based on Example 1, in addition to the case where cod liver oil is applied between the two transparent films during manufacturing, this positioning dressing also incorporates an injection hole 7 on the upper transparent film 1 to allow cod liver oil to be injected into the dressing, considering the shelf life of cod liver oil and environmental protection to reduce waste. When the positioning dressing is needed, the injection hole 7 is opened, and a measured amount of cod liver oil is manually injected between the upper transparent film 1 and the lower transparent film 2 using a syringe. This avoids the problem of the entire positioning dressing being discarded due to expired cod liver oil, thus preventing waste. The injection hole 7 is openable and closable, a conventional structure, and will not be further described or limited.

[0022] This positioning patch does not involve any metal materials, so it will not cause magnetic field interference during MRI scans. Furthermore, the medical PU film itself adheres to the skin, making it convenient and quick to use. It will not easily fall off the skin and is highly practical.

[0023] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0024] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
