Description

Technical Field

[0001] The utility model relates to the technical field of magnetic resonance, in particular to a magnetic resonance patient restraint noise reduction and vibration reduction device. Background Art

[0002] Magnetic resonance imaging is a technology that uses the principle of nuclear magnetic resonance to reconstruct images. It has no ionizing radiation and can reflect the abnormalities and early lesions of human organs from within the human molecules. It is a widely used clinical imaging method.

[0003] However, magnetic resonance imaging is also limited by its imaging principle. During scanning, the switching of the gradient field will produce obvious vibration and loud noise, which is particularly noticeable to patients in a narrow cavity. The commonly used noise reduction method is usually to equip patients with special earplugs, but under the rigid frame of magnetic resonance imaging, the vibration is basically not improved, and some noise is still conducted to the patient through solid bones, which will cause patients to feel a certain degree of discomfort. Magnetic resonance imaging examinations take a long time, ranging from a few minutes to dozens of minutes. Under the influence of the narrow cavity and noise vibration, it is difficult for patients to maintain a posture. Especially the head, most patients will shake, resulting in artifacts, unclear imaging, etc. Magnetic resonance coils are relatively sophisticated electronic devices. If they are not properly protected during transportation, their performance may also be reduced.

[0004] Therefore, how to provide a vibration reduction device that can restrain patients and reduce the discomfort caused by vibration to patients, as well as better facilitate transportation, is a technical problem that technical personnel in this field currently need to solve.

[0038] That is to say, when the patient undergoes an MRI examination, the patient lies on the scanning bed 1, the head coil is put on the patient's head, and the patient's head is completely fixed in the coil through the head cushioning component, and the body area to be examined is restrained on the scanning bed 1 through the body restraining component, and finally the patient is sent to the MRI center for examination; with such an arrangement, during MRI, the patient's head is fixed in the head coil 2 by the first inflatable airbag 3, and the body is also fixed on the scanning bed 1 by the second inflatable airbag 4, so that the vibration of the patient's head and body can be reduced, thereby reducing the noise generated by the vibration of the patient, therefore, this can reduce the patient's discomfort and effectively prevent the patient from shaking and causing poor imaging effect; in addition, when transporting the head coil 2, the head cushioning component can also be wrapped around the outside of the head coil 2 to play a protective role.

[0039] Preferably, the first inflatable airbag 3 and the second inflatable airbag 4 both have a double-layer sandwich structure, and a sound-absorbing sponge 5 is provided in the sandwich layer between the first inflatable airbag 3 and the second inflatable airbag 4 .

[0040] Specifically, Figure 5 As shown, the first inflatable airbag 3 and the second inflatable airbag 4 are both double-layer structures with interlayers, and the interlayer between the outer layer and the inner layer of the first inflatable airbag 3 and the second inflatable airbag 4 is filled with sound-absorbing sponge 5, which can simultaneously reduce noise, reduce vibration and improve comfort.

[0041] Preferably, the first inflatable airbag 3 and the second inflatable airbag 4 are connected by Velcro 6 provided on both sides.

[0042] It can be understood that in the present embodiment, the head cushion component and the body restraint component are respectively composed of a plurality of first inflatable airbags 3 and a plurality of second inflatable airbags 4 connected together, and each first inflatable airbag 3 and each second inflatable airbag 4 are independent individuals and can be freely disassembled and installed.

[0043] Preferably, the first inflatable airbag 3 and the second inflatable airbag 4 are connected by buckles provided on both sides.

[0044] In addition, the first inflatable airbag 3 and the second inflatable airbag 4 can also be connected by buckles arranged on both sides, so that the connection can be more stable.

[0045] Of course, in addition to the two connection methods described above, other connection methods can be selected for the first inflatable airbag 3 and the second inflatable airbag 4 according to actual conditions, as long as the purpose can be achieved.

[0046] Preferably, the sides of the first inflatable airbag 3 and the second inflatable airbag 4 are both provided with air nozzles 7 for inflation and deflation.

[0047] It can be understood that the first inflatable airbag 3 and the second inflatable airbag 4 are both airbags that can be inflated and deflated. An air nozzle 7 is provided on the empty side edges of the first inflatable airbag 3 and the second inflatable airbag 4. The air nozzle 7 can be used for inflation and also for deflation. This arrangement allows the first inflatable airbag 3 and the second inflatable airbag 4 to be reused, thereby reducing the cost of use.

[0048] When the embodiment of the utility model is in use, the first inflatable airbag 3 is firstly adhered to the inner wall of the head coil 2 by the Velcro 6, the patient lies on the scanning bed 1, the head coil sleeve 2 is placed on the patient's head, and then the first inflatable airbag 3 is inflated by the air nozzle 7, so that the patient's head is fixed in the head coil sleeve 2, and the patient's body is restrained in the same way. The second inflatable airbag 4 is adhered to the scanning bed 1, and the body can be fixed after inflation. After the examination is completed, the first inflatable airbag 3 and the second inflatable airbag 4 can be deflated through the air nozzle 7.

[0049] Preferably, a disconnecting stop valve is provided in the gas nozzle 7.

[0050] It can be understood that in order to prevent the gas from being unable to remain inside the first inflatable airbag 3 and the second inflatable airbag 4 after being filled with gas, a disconnect valve is provided at the air nozzle 7. The disconnect valve can prevent the gas from flowing out of the first inflatable airbag 3 and the second inflatable airbag 4 under the action of external force, so that the first inflatable airbag 3 and the second inflatable airbag 4 can function stably.

The sound-absorbing sponge 5 is a soft material, which can effectively reduce the vibration of the patient on the scanning bed 1. The sound-absorbing sponge 5 also has sound absorption and can absorb the noise generated by the vibration very well. In addition, the sound-absorbing sponge 5 can improve the comfort of the patient due to its soft material.
