Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and in particular relates to a device for assisting body positioning during cardiac ultrasound examination. Background Art

[0002] Cardiac ultrasound, also known as echocardiography, is a medical examination that uses ultrasound technology to noninvasively assess the structure and function of the heart. This technology uses an ultrasound probe to transmit sound waves and receive reflected sound waves, forming an image of the heart. This provides real-time visualization of the heart's pulsation, blood flow, and the structure and function of the heart and major blood vessels.

[0003] Cardiac ultrasound is safe, painless, and radiation-free, making it widely used clinically and one of the preferred methods for diagnosing heart disease. It can assess the size, shape, and movement of the heart, test the function of heart valves, observe myocardial hypertrophy or ischemia, assess the presence of pericardial effusion, and analyze cardiac hemodynamics. Furthermore, cardiac ultrasound can be used to diagnose a variety of heart conditions, including congenital heart disease, cardiomyopathy, and coronary artery disease.

[0004] During a cardiac ultrasound examination, the patient typically lies supine or in the left lateral position. After applying coupling gel to the patient's chest, the doctor scans the heart with a probe. During the examination, the patient is advised to breathe calmly and avoid moving or talking to ensure image quality. After the examination, the doctor will analyze the image results, diagnose the condition, and prescribe a treatment plan.

[0005] In short, cardiac ultrasound is an important means of examining heart disease. It can provide doctors with accurate information on heart structure and function, and contribute to the early detection and treatment of heart disease.

[0006] In existing cardiac ultrasound examinations, awake patients are usually examined by the patient maintaining a supine or left lateral position under the guidance of the examining physician. Comatose patients require multiple medical staff to manually assist the patient in maintaining a left lateral position. The above operations usually have the following technical problems: 1. Patients without relevant medical knowledge usually have insufficient compliance and find it difficult to adjust to the position required by the examining physician in a timely manner; 2. When the patient maintains a left lateral position, physical energy is consumed and the position is not standardized; 3. For comatose patients, medical staff manually assist the patient in maintaining a left lateral position, which consumes manpower and material resources; 3. The patient's body parts cannot be fixed well, and the fixation of the head when the body is lying on the side is usually ignored;

[0007] Therefore, it is necessary to provide a device for assisting in positioning the patient during cardiac ultrasound examination, which can be used to stabilize the patient's body and assist the patient in maintaining a standard left lateral decubitus position during cardiac ultrasound examination.

After fixation, the rotation of the base plate 201 drives the patient's body to lie on its side, meeting the body position required for cardiac ultrasound examination;

[0044] The various components within the body fixation mechanism 2 of the present invention are configured with different structures according to the characteristics of the constrained parts. Specifically, due to the musculoskeletal structure of the shoulder's anatomy, a bent plate-like structure is selected; the front surface of the waist and abdomen has no bone support and is more sensitive to hard materials. Therefore, the present invention uses a flexible restraint belt for the fixation of the waist and abdomen, which not only maintains a tight fit but also provides comfort; because the legs are long, the leg restraint mechanism 204 of the present application is a flip-and-cover structure, which is flipped and covered after the legs are placed, forming a wrapping limit for the legs, so that the legs will not fall when the patient's body turns to lie on their side. In particular, the leg restraint mechanism 204 is constrained and limited from the patient's knee joint position, rather than from the thigh root or only from the calf or ankle joint, so the restraint is more stable;

[0045] In this embodiment, the support and fixing mechanism 3 includes a lifting component 301 and a U-shaped splint 302, and the lifting component 301 and the U-shaped splint 302 are respectively rotatably mounted at the ends of both sides of the base plate 201; the equal length extension and contraction of the lifting component 301 drives the base plate 201 to rotate relative to the U-shaped splint 302; the support and fixing mechanism 3 of the present invention has the overall function of adapting to the examination bed for use, and the lifting component 310 is responsible for lifting the patient's body from the right side so that the patient's body assumes the left lateral position required for cardiac ultrasound examination; the U-shaped splint 302 is a structure for fixing the device to one side of the bed;
