Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical accessories, and in particular relates to a nuclear magnetic resonance head supporting device. Background Art
[0002] First of all, when undergoing a head MRI examination, patients need to keep their heads as still as possible or minimize head movement. This is mainly because the strong magnetic field generated by the MRI equipment will affect the patient's head, and any slight head movement may cause the image to be blurred, affecting the diagnosis effect. Therefore, patients need to exert more self-control during the examination and cooperate with the guidance of medical staff.
[0003] Secondly, because patients need to keep their heads still, medical staff can only communicate through microphone broadcasts. This method is feasible for adult patients, but it is difficult for young children and the elderly. Young children are active by nature and it is difficult for them to keep their heads still for a long time; and the elderly may not be able to accurately hear the instructions of medical staff due to hearing loss. This leads to the need for medical staff to frequently intervene when these patients undergo MRI examinations to ensure the smooth progress of the examination. Utility Model Content
[0004] In order to solve the problems raised in the above-mentioned background technology, the utility model provides a head support device for nuclear magnetic resonance, including a head support body and a neck support body. The head support body includes a first support body, a second support body, gauze, and a plug block. The first support body and the second support body are connected by a buckle block. The first support body and the second support body are both provided with a groove. The two side walls of the groove are both provided with a fitting groove matched with the gauze. The end of the gauze passes through the fitting groove, and the end of the gauze is connected to the side wall of the first support body or the second support body through a plug block.
[0005] Furthermore, a void avoidance groove is provided in the groove.
[0006] Furthermore, a grip rod is provided in the air avoidance groove.
[0007] Furthermore, the side walls of the first supporting body and the second supporting body are both provided with gap grooves adapted to the plugging block.
[0008] Furthermore, buckling grooves adapted to the buckle blocks are provided at the top end of the first support body and the bottom end of the second support body.
[0009] The beneficial effects of the utility model are as follows: the patient's head can be limited by two pieces of gauze, and the patient's head can be stably fixed to avoid the influence of head movement on the examination process; the head of patients with different head circumferences can be effectively fixed by adjusting the tightness of the two pieces of gauze, and the applicability is better; the air avoidance groove is provided for lightweighting on the one hand, which can reduce the weight of the first support body and the second support body, and on the other hand, it avoids blocking the patient's line of sight and prevents the patient from panicking because of the blocked line of sight and unable to see anything. The doctor can also observe the patient's pupil state in time according to the air avoidance groove, and make the patient feel comfortable during the examination through a more humane design.

DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-5The utility model provides the following technical solutions: a nuclear magnetic resonance head support device, including a head support body and a neck support body 5, the head support body includes a first support body 1, a second support body 2, a gauze 3, and a plug 4, the first support body 1 and the second support body 2 are connected by a buckle block 6, the first support body 1 and the second support body 2 are both provided with a groove 7, and the two side walls of the groove 7 are both provided with a fitting groove 8 adapted to the gauze 3, the end of the gauze 3 passes through the fitting groove 8, and the end of the gauze 3 is connected to the side wall of the first support body 1 or the second support body 2 through the plug 4.
[0018] In this embodiment, a clearance groove 9 is provided in the groove 7 .
[0019] The above structure can reduce the weight of the first support body 1 and the second support body 2 on the one hand, and avoid blocking the patient's line of sight and preventing the patient from panicking because he cannot see anything due to blocked line of sight. The doctor can also observe the patient's pupil state in time according to the air avoidance groove 9.
[0020] In this embodiment, a grip rod 10 is disposed in the air-avoiding groove 9 .
[0021] By adopting the above structure, a holding position is provided, and the first support body 1 or the second support body 2 is conveniently held by the gripping rod 10 .
[0022] In this embodiment, the side walls of the first supporting body and the second supporting body are both provided with a clearance groove 11 adapted to the plug 4 .
[0023] With the above structure, when the gauze 3 is located in the gap groove 11 , the plug 4 is interference fit with the gap groove 11 , thereby effectively limiting the end of the gauze 3 .
[0024] In this embodiment, a buckling groove 12 adapted to the buckle block 6 is formed at the top end of the first support body and the bottom end of the second support body.
[0025] By adopting the above structure, the relative position of the first support body and the second support body can be effectively limited, thereby preventing the patient's head from moving during magnetic resonance imaging, which would result in poor imaging.
[0026] Method of use: The medical staff respectively pass the two ends of the first gauze 3 through the fitting groove 8 on the first support body, and fix the end of the first gauze 3 in the gap groove 11 of the first support body 1 through the plug block 4. At this time, the first gauze 3 is in a straight state (still has toughness); the medical staff respectively pass the two ends of the second gauze 3 through the fitting groove 8 on the second support body and keep them for use. The medical staff lets the patient lie on the moving platform 13, with the patient's neck leaning on the neck support body 5 and the back of the patient's head leaning on the first gauze 3, puts the second support body on the first support body, and connects the first support body and the second support body through the buckle block 6. The medical staff asks the patient to look directly at the grip 10 to make sure that the patient's head is upright. The medical staff tightens the second gauze 3 and fixes the second gauze 3 in the gap groove 11 of the second support body through the plug 4. The first gauze 3 fits the patient's forehead, and the first gauze 3 and the second gauze 3 are both taut. At this time, the patient's head cannot move. After completing the above steps, an MRI can be performed. After completing the MRI, the medical staff removes the plug 4 on the second support body, and then removes the second support body from the first support body. The patient leaves the moving platform 13, and the medical staff replaces two gauzes 3 to effectively avoid cross infection.
