Abstract
Description
Technical Field
[0001] This utility model relates to the field of imaging examination auxiliary equipment technology, specifically to an auxiliary component for MRI examination of kyphotic patients. Background Technology
[0002] Magnetic resonance imaging (MRI) is an imaging diagnostic method that uses magnetic field resonance to generate signals. This technology is one of the most important imaging tools in clinical medical diagnosis and basic life science research, characterized by its non-invasive nature, high soft tissue contrast, numerous imaging parameters and contrast ratios, and rich image information. It has a wide range of clinical indications and is the preferred examination method for lesions in the brain, spinal cord, abdominal and pelvic regions, and bones and joints.
[0003] During MRI scans of the head and neck, patients often need to lie flat with their heads placed inside the head-neck syndesmotic coil for the scan to take place. However, when performing cranial or cervical spine MRI scans on patients with kyphosis (hunchback), the hunchback patient's head is partially suspended in the air and cannot be placed inside the head-neck syndesmotic coil, making scanning impossible. Lying on their side increases the difficulty of the scan and the inaccuracy of the scan images, causing difficulties in diagnosis.
[0004] While many technologies have emerged to address this problem, the most widely used product currently is an auxiliary assembly that combines a wedge-shaped pad with pad legs for placement on the wedge-shaped pad.
[0005] However, the aforementioned technologies are mainly designed for patients with mild to moderate kyphosis. When used for examinations of patients with severe kyphosis, not only is the patient's hip and waist not sufficiently lifted, but also, because the wedge-shaped pad is too close to the patient's back, there is either no place to place the leg support column on the wedge-shaped pad, or it causes the patient's center of gravity to shift backward, increasing the pressure on the legs from the leg support column. In addition, the MRI examination takes a long time, and patients are prone to leg numbness and other discomfort. After the examination, patients with leg numbness have difficulty standing up quickly and independently, which also affects the efficiency of the examination. It is difficult to use MRI examinations for patients with severe kyphosis. If the wedge-shaped pad of this technology is thickened, the angle is increased, and the length is lengthened, although it can meet the needs of patients with severe kyphosis, the user experience is poor when used for most patients with mild to moderate kyphosis. Preparing an extra set not only increases the cost, but also takes up more storage space and cleaning and maintenance work. Utility Model Content
[0006] The purpose of this invention is to provide an auxiliary component for MRI examination of kyphotic patients that is easy to adjust and can be used for examinations of more types of kyphotic patients.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] This utility model provides an auxiliary component for MRI examination of kyphotic patients, including a wedge-shaped pad and a leg support column for placement on the wedge-shaped pad. The wedge-shaped pad includes a wedge block and a support plate. One side of the support plate is rotatably connected to the flat end of the wedge block, and the lower side of the support plate is close to or in contact with the upper side of the wedge block.
[0009] Preferably, the support plate includes a liner and a soft layer covering the outside of the liner, and the support plate is connected to the wedge block through the soft layer.
[0010] Preferably, the angle of the flat end (front end) of the wedge block is between 8° and 20°.
[0011] Preferably, both the soft layer and the wedge are made of foamed plastic.
[0012] Preferably, the soft layer is polyurethane foam.
[0013] Preferably, the liner is a rigid plastic sheet.
[0014] Preferably, the liner has a plurality of holes, which are used to reduce weight and enhance the tightness of the connection between the liner and the soft layer.
[0015] Preferably, the pad column includes a hollow cylinder and a small-diameter cylinder, at least one end of the hollow cylinder is provided with a socket, and the small-diameter cylinder is inserted into the socket.
[0016] Preferably, at least one end of the small-diameter cylinder is provided with a groove for easy gripping.
[0017] Preferably, the outer diameter of the hollow cylinder is between 20cm and 35cm.
[0018] Preferably, the outer diameter of the small-diameter cylinder is between 6 cm and 12 cm.
[0019] Preferably, the support column is made of polyurethane foam.
[0020] Preferably, the outer surface of the small-diameter cylinder is connected with a Velcro fastener, and the lower surface of the support plate is connected with a Velcro fastener that can cooperate with the Velcro fastener on the outer surface of the small-diameter cylinder.
[0021] Due to the adoption of the above technical solutions, the advantages of this utility model are as follows:
[0022] 1. This utility model allows for adjustment of the front angle of the wedge pad by removing the small-diameter cylinder from the insertion hole of the hollow cylinder and placing it between the top of the wedge block and the bottom of the support plate. This is suitable for patients with severe kyphosis to undergo MRI examinations. After the examination, the small-diameter cylinder can be reinserted into the insertion hole for storage. This not only makes storage, adjustment, and use convenient, but also allows the device to be used for examinations of patients with mild to moderate kyphosis, just like existing auxiliary components, after the small-diameter cylinder is stored.
[0023] 2. The size and usage of this utility model are basically the same as the existing technology. Furthermore, when assisting patients with severe kyphosis in MRI examinations, there is no need to prepare a set of wedge-shaped pads that have been lengthened and thickened, which reduces procurement costs, space occupied by examination auxiliary components, and management costs such as disinfection.
[0024] 3. This utility model has a simple structure and low cost. Attached Figure Description
